batman-adv: Fix unexpected free of bcast_own on add_if error
The function batadv_iv_ogm_orig_add_if allocates new buffers for bcast_own
and bcast_own_sum. It is expected that these buffers are unchanged in case
either bcast_own or bcast_own_sum couldn't be resized.
But the error handling of this function frees the already resized buffer
for bcast_own when the allocation of the new bcast_own_sum buffer failed.
This will lead to an invalid memory access when some code will try to
access bcast_own.
Instead the resized new bcast_own buffer has to be kept. This will not lead
to problems because the size of the buffer was only increased and therefore
no user of the buffer will try to access bytes outside of the new buffer.

batman-adv: Avoid duplicate neigh_node additions
Two parallel calls to batadv_neigh_node_new() might race for creating
and adding the same neig_node. Fix this by including the check for any
already existing, identical neigh_node within the spin-lock.
This fixes splats like the following:

The undefined behavior sanatizer detected an signed integer overflow in a

UBSAN: Undefined behaviour in net/batman-adv/bat_iv_ogm.c:1246:25
signed integer overflow:
8713350 * 255 cannot be represented in type 'int'
The problems happens because the calculation of mixed unsigned and signed
integers resulted in an integer multiplication.
batadv_ogm_packet::tq (u8 255)
* tq_own (u8 255)
* tq_asym_penalty (int 134; max 255)
* tq_iface_penalty (int 255; max 255)
The tq_iface_penalty, tq_asym_penalty and inv_asym_penalty can just be
changed to unsigned int because they are not expected to become negative.

batman-adv: Check hard_iface refcnt before calling function
The batadv_hardif_list list is checked in many situations and the items
in this list are given to specialized functions to modify the routing
behavior. At the moment each of these called functions has to check
itself whether the received batadv_hard_iface has a refcount > 0 before
it can increase the reference counter and use it in other objects.
This can easily lead to problems because it is not easily visible where
all callers of a function got the batadv_hard_iface object from and
whether they already hold a valid reference.
Checking the reference counter directly before calling a subfunction
with a pointer from the batadv_hardif_list avoids this problem.

The problem occurs because netem is not prepared to handle GSO packets (as it
uses skb_checksum_help in its enqueue path, which cannot manipulate these
frames).
The solution I think is to simply segment the skb in a simmilar fashion to the
way we do in __dev_queue_xmit (via validate_xmit_skb), with some minor changes.
When we decide to corrupt an skb, if the frame is GSO, we segment it, corrupt
the first segment, and enqueue the remaining ones.
tested successfully by myself on the latest net kernel, to which this applies

as it would prevent the netdev objects references by batman-adv from
being released after shutdown.

gre: do not pull header in ICMP error processing
iptunnel_pull_header expects that IP header was already pulled; with this
expectation, it pulls the tunnel header. This is not true in gre_err.
Furthermore, ipv4_update_pmtu and ipv4_redirect expect that skb->data points
to the IP header.
We cannot pull the tunnel header in this path. It's just a matter of not
calling iptunnel_pull_header - we don't need any of its effects.

net: Implement net_dbg_ratelimited() for CONFIG_DYNAMIC_DEBUG case
Prior to commit d92cff89a0c8 ("net_dbg_ratelimited: turn into no-op
when !DEBUG") the implementation of net_dbg_ratelimited() was buggy
for both the DEBUG and CONFIG_DYNAMIC_DEBUG cases.
The bug was that net_ratelimit() was being called and, despite
returning true, nothing was being printed to the console. This
resulted in messages like the following -
"net_ratelimit: %d callbacks suppressed"
with no other output nearby.
After commit d92cff89a0c8 ("net_dbg_ratelimited: turn into no-op when
!DEBUG") the bug is fixed for the DEBUG case. However, there's no
output at all for CONFIG_DYNAMIC_DEBUG case.
This patch restores debug output (if enabled) for the
CONFIG_DYNAMIC_DEBUG case.
Add a definition of net_dbg_ratelimited() for the CONFIG_DYNAMIC_DEBUG
case. The implementation takes care to check that dynamic debugging is
enabled before calling net_ratelimit().

tipc: only process unicast on intended node
We have observed complete lock up of broadcast-link transmission due to
unacknowledged packets never being removed from the 'transmq' queue. This
is traced to nodes having their ack field set beyond the sequence number
of packets that have actually been transmitted to them.
Consider an example where node 1 has sent 10 packets to node 2 on a
link and node 3 has sent 20 packets to node 2 on another link. We
see examples of an ack from node 2 destined for node 3 being treated as
an ack from node 2 at node 1. This leads to the ack on the node 1 to node
2 link being increased to 20 even though we have only sent 10 packets.
When node 1 does get around to sending further packets, none of the
packets with sequence numbers less than 21 are actually removed from the
transmq.
To resolve this we reinstate some code lost in commit d999297c3dbb ("tipc:
reduce locking scope during packet reception") which ensures that only
messages destined for the receiving node are processed by that node. This
prevents the sequence numbers from getting out of sync and resolves the
packet leakage, thereby resolving the broadcast-link transmission
lock-ups we observed.
While we are aware that this change only patches over a root problem that
we still haven't identified, this is a sanity test that it is always
legitimate to do. It will remain in the code even after we identify and
fix the real problem.

cxgb3: fix out of bounds read
An out of bounds read of 2 bytes was discovered in cxgb3 with KASAN.
t3_config_rss() expects both arrays it gets as parameters to have
terminators. setup_rss(), the caller, forgets to add a terminator to
one of the arrays. Thankfully the iteration in t3_config_rss() stops
anyway, but in the last iteration the check for the terminator
is an out of bounds read.
Add the missing terminator to rspq_map[].

net/smscx5xx: use the device tree for mac address
This takes the MAC address for smsc75xx/smsc95xx USB network devices
from a the device tree. This is required to get a usable persistent
address on the popular beagleboard, whose hardware designers
accidentally forgot that an ethernet device really requires an a
MAC address to be functional.
The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores
the MAC address in ROM accessible via VC4 firmware.
The smsc75xx and smsc95xx drivers are just two copies of the
same code, so better fix both.

net: l2tp: fix reversed udp6 checksum flags
This patch fixes a bug which causes the behavior of whether to ignore
udp6 checksum of udp6 encapsulated l2tp tunnel contrary to what
userspace program requests.
When the flag `L2TP_ATTR_UDP_ZERO_CSUM6_RX` is set by userspace, it is
expected that udp6 checksums of received packets of the l2tp tunnel
to create should be ignored. In `l2tp_netlink.c`:
`l2tp_nl_cmd_tunnel_create()`, `cfg.udp6_zero_rx_checksums` is set
according to the flag, and then passed to `l2tp_core.c`:
`l2tp_tunnel_create()` and then `l2tp_tunnel_sock_create()`. In
`l2tp_tunnel_sock_create()`, `udp_conf.use_udp6_rx_checksums` is set
the same to `cfg.udp6_zero_rx_checksums`. However, if we want the
checksum to be ignored, `udp_conf.use_udp6_rx_checksums` should be set
to `false`, i.e. be set to the contrary. Similarly, the same should be
done to `udp_conf.use_udp6_tx_checksums`.

gpiolib-acpi: Duplicate con_id string when adding it to the crs lookup list
Calling gpiod_get() from a module and then unloading the module leads to an
oops due to acpi_can_fallback_to_crs() storing the pointer to the passed
'con_id' string onto acpi_crs_lookup_list. The next guy to come along will then
try to access the string but the memory may now be gone with the module.
Make a copy of the passed string instead, and store the copy on the list.

"Final set of -rc fixes for 4.6.
I've collected up a number of patches that are all pretty small with
the exception of only a couple. The hfi1 driver has a number of
important patches, and it is what really drives the line count of this
pull request up. These are all small and I've got this kernel built
and running in the test lab (I have most of the hardware, I think nes
is the only thing in this patch set that I can't say I've personally
tested and have up and running).
Summary:
- A number of collected fixes for oopses, memory corruptions,
deadlocks, etc. All of these fixes are small (many only 5-10
lines), obvious, and tested.
- Fix for the security issue related to the use of write for

ip_tunnel: fix preempt warning in ip tunnel creation/updating
After the commit e09acddf873b ("ip_tunnel: replace dst_cache with generic
implementation"), a preemption debug warning is triggered on ip4
tunnels updating; the dst cache helper needs to be invoked in unpreemptible
context.
We don't need to load the cache on tunnel update, so this commit fixes
the warning replacing the load with a dst cache reset, which is
preempt safe.

EDAC: i7core, sb_edac: Don't return NOTIFY_BAD from mce_decoder callback
Both of these drivers can return NOTIFY_BAD, but this terminates
processing other callbacks that were registered later on the chain.
Since the driver did nothing to log the error it seems wrong to prevent
other interested parties from seeing it. E.g. neither of them had even
bothered to check the type of the error to see if it was a memory error
before the return NOTIFY_BAD.

kcov: don't trace the code coverage code
Kcov causes the compiler to add a call to __sanitizer_cov_trace_pc() in
every basic block. Ftrace patches in a call to _mcount() to each
function it has annotated.
Letting these mechanisms annotate each other is a bad thing. Break the
loop by adding 'notrace' to __sanitizer_cov_trace_pc() so that ftrace
won't try to patch this code.
This patch lets arm64 with KCOV and STACK_TRACER boot.

mm: wake kcompactd before kswapd's short sleep
When kswapd goes to sleep it checks if the node is balanced and at first
it sleeps only for HZ/10 time, then rechecks if the node is still
balanced and nobody has woken it during the initial sleep. Only then it
goes fully sleep until an allocation slowpath wakes it up again.
For higher-order allocations, waking up kcompactd is done only before
the full sleep. This turns out to be an issue in case another
high-order allocation fails during the initial sleep. It will wake
kswapd up, however kswapd considers the zone balanced from the order-0
perspective, and will just quickly try to sleep again. So if there's a
longer stream of high-order allocations hitting the slowpath and waking
up kswapd, it might never actually wake up kcompactd, which may be
considered a regression from kswapd-based compaction. In the worst
case, it might be that a single allocation that cannot direct
reclaim/compact itself is waking kswapd in the retry loop and preventing
kcompactd from being woken up and unblocking it.
This patch makes sure kcompactd is woken up in such situations by simply
moving the wakeup before the short initial sleep. More efficient
solution would be to wake kcompactd immediately instead of kswapd if the
node is already order-0 balanced, but in that case we should also move
reset_isolation_suitable() call to kcompactd so it's not adding to the
allocator's latency. Since it's late in the 4.6 cycle, let's go with
the simpler change for now.

Currently, migration code increses num_poisoned_pages on *failed*

numa: fix /proc/<pid>/numa_maps for THP
In gather_pte_stats() a THP pmd is cast into a pte, which is wrong
because the layouts may differ depending on the architecture. On s390
this will lead to inaccurate numa_maps accounting in /proc because of
misguided pte_present() and pte_dirty() checks on the fake pte.
On other architectures pte_present() and pte_dirty() may work by chance,
but there may be an issue with direct-access (dax) mappings w/o
underlying struct pages when HAVE_PTE_SPECIAL is set and THP is
available. In vm_normal_page() the fake pte will be checked with
pte_special() and because there is no "special" bit in a pmd, this will
always return false and the VM_PFNMAP | VM_MIXEDMAP checking will be
skipped. On dax mappings w/o struct pages, an invalid struct page
pointer would then be returned that can crash the kernel.
This patch fixes the numa_maps THP handling by introducing new "_pmd"
variants of the can_gather_numa_stats() and vm_normal_page() functions.

mm/huge_memory: replace VM_NO_THP VM_BUG_ON with actual VMA check
Khugepaged detects own VMAs by checking vm_file and vm_ops but this way
it cannot distinguish private /dev/zero mappings from other special
mappings like /dev/hpet which has no vm_ops and popultes PTEs in mmap.
This fixes false-positive VM_BUG_ON and prevents installing THP where
they are not expected.

thp: keep huge zero page pinned until tlb flush
Andrea has found[1] a race condition on MMU-gather based TLB flush vs
split_huge_page() or shrinker which frees huge zero under us (patch 1/2
and 2/2 respectively).
With new THP refcounting, we don't need patch 1/2: mmu_gather keeps the
page pinned until flush is complete and the pin prevents the page from
being split under us.
We still need patch 2/2. This is simplified version of Andrea's patch.
We don't need fancy encoding.

mm: exclude HugeTLB pages from THP page_mapped() logic
HugeTLB pages cannot be split, so we use the compound_mapcount to track
rmaps.
Currently page_mapped() will check the compound_mapcount, but will also
go through the constituent pages of a THP compound page and query the
individual _mapcount's too.
Unfortunately, page_mapped() does not distinguish between HugeTLB and
THP compound pages and assumes that a compound page always needs to have
HPAGE_PMD_NR pages querying.
For most cases when dealing with HugeTLB this is just inefficient, but
for scenarios where the HugeTLB page size is less than the pmd block
size (e.g. when using contiguous bit on ARM) this can lead to crashes.
This patch adjusts the page_mapped function such that we skip the
unnecessary THP reference checks for HugeTLB pages.

kexec: export OFFSET(page.compound_head) to find out compound tail page
PageAnon() always look at head page to check PAGE_MAPPING_ANON and tail
page's page->mapping has just a poisoned data since commit 1c290f642101
("mm: sanitize page->mapping for tail pages").
If makedumpfile checks page->mapping of a compound tail page to
distinguish anonymous page as usual, it must fail in newer kernel. So
it's necessary to export OFFSET(page.compound_head) to avoid checking
compound tail pages.
The problem is that unnecessary hugepages won't be removed from a dump
file in kernels 4.5.x and later. This means that extra disk space would
be consumed. It's a problem, but not critical.

kexec: update VMCOREINFO for compound_order/dtor
makedumpfile refers page.lru.next to get the order of compound pages for
page filtering.
However, now the order is stored in page.compound_order, hence
VMCOREINFO should be updated to export the offset of
page.compound_order.
The fact is, page.compound_order was introduced already in kernel 4.0,
but the offset of it was the same as page.lru.next until kernel 4.3, so
this was not actual problem.
The above can be said also for page.lru.prev and page.compound_dtor,
it's necessary to detect hugetlbfs pages. Further, the content was
changed from direct address to the ID which means dtor.
The problem is that unnecessary hugepages won't be removed from a dump
file in kernels 4.4.x and later. This means that extra disk space would
be consumed. It's a problem, but not critical.

IB/security: Restrict use of the write() interface
The drivers/infiniband stack uses write() as a replacement for
bi-directional ioctl(). This is not safe. There are ways to
trigger write calls that result in the return structure that
is normally written to user space being shunted off to user
specified kernel memory instead.
For the immediate repair, detect and deny suspicious accesses to
the write API.
For long term, update the user space libraries and the kernel API
to something that doesn't present the same security vulnerabilities
(likely a structured ioctl() interface).
The impacted uAPI interfaces are generally only available if
hardware from drivers/infiniband is installed in the system.

This commit re-arranges the context initialization code in a way that
would allow for context event flags to be used to determine whether
the context has been successfully initialized.
In turn, this can be used to skip the resource de-allocation if they
were never allocated in the first place.

IB/hfi1: Prevent unpinning of wrong pages
The routine used by the SDMA cache to handle already
cached nodes can extend an already existing node.
In its error handling code, the routine will unpin pages
when not all pages of the buffer extension were pinned.
There was a bug in that part of the routine, which would
mistakenly unpin pages from the original set rather than
the newly pinned pages.
This commit fixes that bug by offsetting the page array
to the proper place pointing at the beginning of the newly
pinned pages.

IB/hfi1: Prevent NULL pointer deferences in caching code
There is a potential kernel crash when the MMU notifier calls the
invalidation routines in the hfi1 pinned page caching code for sdma.
The invalidation routine could call the remove callback
for the node, which in turn ends up dereferencing the
current task_struct to get a pointer to the mm_struct.
However, the mm_struct pointer could be NULL resulting in
the following backtrace:

To correct this, the mm_struct passed to us by the MMU notifier is
used (which is what should have been done to begin with). This avoids
the broken derefences and ensures that the correct mm_struct is used.

IB/mlx5: Expose correct max_sge_rd limit
mlx5 devices (Connect-IB, ConnectX-4, ConnectX-4-LX) has a limitation
where rdma read work queue entries cannot exceed 512 bytes.
A rdma_read wqe needs to fit in 512 bytes:
- wqe control segment (16 bytes)
- rdma segment (16 bytes)
- scatter elements (16 bytes each)
So max_sge_rd should be: (512 - 16 - 16) / 16 = 30.

perf/x86/intel: Fix incorrect lbr_sel_mask value
This patch fixes a bug which was introduced by:
b16a5b52eb90 ("perf/x86: Add option to disable reading branch flags/cycles")
In this patch, lbr_sel_mask is used to mask the lbr_select. But LBR_SEL_MASK
doesn't include the bit for LBR_CALL_STACK. So LBR call stack will never be
set in lbr_select.
This patch corrects the LBR_SEL_MASK by including all valid bits in
LBR_SELECT. Also, the LBR_CALL_STACK bit is different as other bit in
LBR_SELECT. It does not operate in suppress mode, so it needs to be
specially handled in intel_pmu_setup_hw_lbr_filter.

perf/x86/intel/pt: Don't die on VMXON
Some versions of Intel PT do not support tracing across VMXON, more
specifically, VMXON will clear TraceEn control bit and any attempt to
set it before VMXOFF will throw a #GP, which in the current state of
things will crash the kernel. Namely:
$ perf record -e intel_pt// kvm -nographic
on such a machine will kill it.
To avoid this, notify the intel_pt driver before VMXON and after
VMXOFF so that it knows when not to enable itself.

would result in installing a counter across the creds boundary.
Fix this by wrapping lots of perf_event_open() in cred_guard_mutex.
This should be fine as perf_event_exit_task() is already called with
cred_guard_mutex held, so all perf locks already nest inside it.

rbd: fix rbd map vs notify races
A while ago, commit 9875201e1049 ("rbd: fix use-after free of
rbd_dev->disk") fixed rbd unmap vs notify race by introducing
an exported wrapper for flushing notifies and sticking it into
do_rbd_remove().
A similar problem exists on the rbd map path, though: the watch is
registered in rbd_dev_image_probe(), while the disk is set up quite
a few steps later, in rbd_dev_device_setup(). Nothing prevents
a notify from coming in and crashing on a NULL rbd_dev->disk:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000050

If an error occurs during rbd map, we have to error out, potentially
tearing down a watch. Just like on rbd unmap, notifies have to be
flushed, otherwise rbd_watch_cb() may end up trying to read in the
image header after rbd_dev_image_release() has run:

To fix this, a) check if RBD_DEV_FLAG_EXISTS is set before calling
revalidate_disk(), b) move ceph_osdc_flush_notifies() call into
rbd_dev_header_unwatch_sync() to cover rbd map error paths and c) turn
header read-in into a critical section. The latter also happens to
take care of rbd map foo@bar vs rbd snap rm foo@bar race.

x86/apic: Handle zero vector gracefully in clear_vector_irq()
If x86_vector_alloc_irq() fails x86_vector_free_irqs() is invoked to cleanup
the already allocated vectors. This subsequently calls clear_vector_irq().
The failed irq has no vector assigned, which triggers the BUG_ON(!vector) in
clear_vector_irq().
We cannot suppress the call to x86_vector_free_irqs() for the failed
interrupt, because the other data related to this irq must be cleaned up as
well. So calling clear_vector_irq() with vector == 0 is legitimate.
Remove the BUG_ON and return if vector is zero,

So firstly scale step value to "millicelsius" and then do division, so
finally we can increase resolution for temperature value. Also refine

sparc64: Fix bootup regressions on some Kconfig combinations.
The system call tracing bug fix mentioned in the Fixes tag
below increased the amount of assembler code in the sequence
of assembler files included by head_64.S
This caused to total set of code to exceed 0x4000 bytes in
size, which overflows the expression in head_64.S that works
to place swapper_tsb at address 0x408000.
When this is violated, the TSB is not properly aligned, and
also the trap table is not aligned properly either. All of
this together results in failed boots.
So, do two things:
1) Simplify some code by using ba,a instead of ba/nop to get
those bytes back.
2) Add a linker script assertion to make sure that if this
happens again the build will fail.

Pull workqueue fix from Tejun Heo:
"So, it turns out we had a silly bug in the most fundamental part of
workqueue for a very long time. AFAICS, this dates back to pre-git
era and has quite likely been there from the time workqueue was first
introduced.
A work item uses its PENDING bit to synchronize multiple queuers.
Anyone who wins the PENDING bit owns the pending state of the work
item. Whether a queuer wins or loses the race, one thing should be
guaranteed - there will soon be at least one execution of the work
item - where "after" means that the execution instance would be able
to see all the changes that the queuer has made prior to the queueing
attempt.
Unfortunately, we were missing a smp_mb() after clearing PENDING for
execution, so nothing guaranteed visibility of the changes that a
queueing loser has made, which manifested as a reproducible blk-mq
stall.
Lots of kudos to Roman for debugging the problem. The patch for
-stable is the minimal one. For v3.7, Peter is working on a patch to
make the code path slightly more efficient and less fragile"

This bug was introduced while converting threadgroup locking to a

path depending on the ability to create new kthreads. cpuset had a
similar issue which was fixed by performing heavy-lifting operations
asynchronous to task migration. The two patches fix the same issue in
memcg in a similar way. The first patch makes the mechanism generic
and the second relocates memcg charge moving outside the migration
path.
Given that we don't want to perform heavy operations while
writelocking threadgroup lock anyway, moving them out of the way is a
desirable solution. One thing to note is that the problem was
difficult to debug because lockdep couldn't figure out the deadlock
condition. Looking into how to improve that"

nios2: memset: use the right constraint modifier for the %4 output operand
Depending on the size of the area to be memset'ed, the nios2 memset implementation
either uses a naive loop (for buffers smaller or equal than 8 bytes) or a more optimized
implementation (for buffers larger than 8 bytes). This implementation does 4-byte stores
rather than 1-byte stores to speed up memset.
However, we discovered that on our nios2 platform, memset() was not properly setting the
buffer to the expected value. A memset of 0xff would not set the entire buffer to 0xff, but to:
0xff 0x00 0xff 0x00 0xff 0x00 0xff 0x00 ...
Which is obviously incorrect. Our investigation has revealed that the problem lies in the
incorrect constraints used in the inline assembly.
The following piece of assembly, from the nios2 memset implementation, is supposed to
create a 4-byte value that repeats 4 times the 1-byte pattern passed as memset argument:
/* fill8 %3, %5 (c & 0xff) */
" slli %4, %5, 8\n"
" or %4, %4, %5\n"
" slli %3, %4, 16\n"
" or %3, %3, %4\n"
However, depending on the compiler and optimization level, this code might be compiled as:
34: 280a923a slli r5,r5,8
38: 294ab03a or r5,r5,r5
3c: 2808943a slli r4,r5,16
40: 2148b03a or r4,r4,r5
This is wrong because r5 gets used both for %5 and %4, which leads to the final pattern
stored in r4 to be 0xff00ff00 rather than the expected 0xffffffff.
%4 is defined with the "=r" constraint, i.e as an output operand. However, as explained in
http://www.ethernut.de/en/documents/arm-inline-asm.html, this does not prevent gcc from
using the same register for an output operand (%4) and input operand (%5). By using the
constraint modifier '&', we indicate that the register should be used for output only. With this
change, we get the following assembly output:
34: 2810923a slli r8,r5,8
38: 4150b03a or r8,r8,r5
3c: 400e943a slli r7,r8,16
40: 3a0eb03a or r7,r7,r8
Which correctly produces the 0xffffffff pattern when 0xff is passed as the memset() pattern.
It is worth mentioning the observed consequence of this bug: we were hitting the kernel
BUG() in mm/bootmem.c:__free() that verifies when marking a page as free that it was
previously marked as occupied (i.e that the bit was set to 1). The entire bootmem bitmap is
set to 0xff bit via a memset() during the bootmem initialization. The bootmem_free() call right
after the initialization was finding some bits to be set to 0, which didn't make sense since the
bitmap has just been memset'ed to 0xff. Except that due to the bug explained above, the
bitmap was in fact initialized to 0xff00ff00.

s390/sclp_ctl: fix potential information leak with /dev/sclp
The sclp_ctl_ioctl_sccb function uses two copy_from_user calls to
retrieve the sclp request from user space. The first copy_from_user
fetches the length of the request which is stored in the first two
bytes of the request. The second copy_from_user gets the complete
sclp request, but this copies the length field a second time.
A malicious user may have changed the length in the meantime.

cxl: Poll for outstanding IRQs when detaching a context
When detaching contexts, we may still have interrupts in the system
which are yet to be delivered to any CPU and be acked in the PSL.
This can result in a subsequent unrelated process getting an spurious
IRQ or an interrupt for a non-existent context.
This polls the PSL to ensure that the PSL is clear of IRQs for the
detached context, before removing the context from the idr.

cxl: Keep IRQ mappings on context teardown
Keep IRQ mappings on context teardown. This won't leak IRQs as if we
allocate the mapping again, the generic code will give the same
mapping used last time.
Doing this works around a race in the generic code. Masking the
interrupt introduces a race which can crash the kernel or result in
IRQ that is never EOIed. The lost of EOI results in all subsequent
mappings to the same HW IRQ never receiving an interrupt.
We've seen this race with cxl test cases which are doing heavy context
startup and teardown at the same time as heavy interrupt load.
A fix to the generic code is being investigated also.

drm/dp/mst: Restore primary hub guid on resume
Some hubs are forgetful, and end up forgetting whatever GUID we set
previously after we do a suspend/resume cycle. This can lead to
hotplugging breaking (along with probably other things) since the hub
will start sending connection notifications with the wrong GUID. As
such, we need to check on resume whether or not the GUID the hub is
giving us is valid.

We can thank KASAN for finding this, otherwise I probably would have spent

Revert "x86/mm/32: Set NX in __supported_pte_mask before enabling paging"
This reverts commit 320d25b6a05f8b73c23fc21025d2906ecdd2d4fc.
This change was problematic for a couple of reasons:
1. It missed a some entry points (Xen things and 64-bit native).
2. The entry it changed can be executed more than once. This isn't
really a problem, but it conflated per-cpu state setup and global
state setup.
3. It broke 64-bit non-NX. 64-bit non-NX worked the other way around from
32-bit -- __supported_pte_mask had NX set initially and was *cleared*
in x86_configure_nx. With the patch applied, it never got cleared.

RDMA/iw_cxgb4: Fix bar2 virt addr calculation for T4 chips
For T4, kernel mode qps don't use the user doorbell. User mode qps during
flow control db ringing are forced into kernel, where user doorbell is
treated as kernel doorbell and proper bar2 offset in bar2 virtual space is
calculated, which incase of T4 is a bogus address, causing a kernel panic
due to illegal write during doorbell ringing.
In case of T4, kernel mode qp bar2 virtual address should be 0. Added T4
check during bar2 virtual address calculation to return 0. Fixed Bar2
range checks based on bar2 physical address.
The below oops will be fixed

The underlying device is a null_blk, with default parameters:
queue_mode = MQ
submit_queues = 1
Verification that nullb0 has something inflight:
root@pserver8:~# cat /sys/block/nullb0/inflight
0 1
root@pserver8:~# find /sys/block/nullb0/mq/0/cpu* -name rq_list -print -exec cat {} \;
...
/sys/block/nullb0/mq/0/cpu2/rq_list
CTX pending:
ffff8838038e2400
...
During debug it became clear that stalled request is always inserted in
the rq_list from the following path:
save_stack_trace_tsk + 34
blk_mq_insert_requests + 231
blk_mq_flush_plug_list + 281
blk_flush_plug_list + 199
wait_on_page_bit + 192
__filemap_fdatawait_range + 228
filemap_fdatawait_range + 20
filemap_write_and_wait_range + 63
blkdev_fsync + 27
vfs_fsync_range + 73
blkdev_write_iter + 202
__vfs_write + 170
vfs_write + 169
kernel_write + 56
So blk_flush_plug_list() was called with from_schedule == true.
If from_schedule is true, that means that finally blk_mq_insert_requests()
offloads execution of __blk_mq_run_hw_queue() and uses kblockd workqueue,
i.e. it calls kblockd_schedule_delayed_work_on().
That means, that we race with another CPU, which is about to execute
__blk_mq_run_hw_queue() work.
Further debugging shows the following traces from different CPUs:
CPU#0 CPU#1
---------------------------------- -------------------------------
reqeust A inserted
STORE hctx->ctx_map[0] bit marked
kblockd_schedule...() returns 1
<schedule to kblockd workqueue>
request B inserted
STORE hctx->ctx_map[1] bit marked
kblockd_schedule...() returns 0
*** WORK PENDING bit is cleared ***
flush_busy_ctxs() is executed, but
bit 1, set by CPU#1, is not observed
As a result request B pended forever.
This behaviour can be explained by speculative LOAD of hctx->ctx_map on
CPU#0, which is reordered with clear of PENDING bit and executed _before_
actual STORE of bit 1 on CPU#1.
The proper fix is an explicit full barrier <mfence>, which guarantees
that clear of PENDING bit is to be executed before all possible
speculative LOADS or STORES inside actual work function.

ALSA: hda - Update BCLK also at hotplug for i915 HSW/BDW
The recent bug report suggests that BCLK setup for i915 HSW/BDW needs
to be updated at each HDMI hotplug, not only at initialization and
resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at
ELD notification, too. Otherwise the HDMI audio may be out of sync
and played in a wrong pitch.
However, the HDA codec driver has no access to the controller
registers, and currently the code managing these registers is in
hda_intel.c, i.e. local to the controller driver. For allowing the
explicit BCLK update from the codec driver, as in this patch, the
former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and
exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA
controller driver and intel_pin_eld_notify() in HDMI codec driver.
Along with this change, snd_hdac_get_display_clk() gets dropped as
it's no longer used.

When the config TDP level is not nominal (level = 0), the MSR values for

memcg: relocate charge moving from ->attach to ->post_attach
Hello,
So, this ended up a lot simpler than I originally expected. I tested
it lightly and it seems to work fine. Petr, can you please test these
two patches w/o the lru drain drop patch and see whether the problem
is gone?
Thanks.
------ 8< ------
If charge moving is used, memcg performs relabeling of the affected
pages from its ->attach callback which is called under both
cgroup_threadgroup_rwsem and thus can't create new kthreads. This is
fragile as various operations may depend on workqueues making forward
progress which relies on the ability to create new kthreads.
There's no reason to perform charge moving from ->attach which is deep
in the task migration path. Move it to ->post_attach which is called
after the actual migration is finished and cgroup_threadgroup_rwsem is
dropped.
* move_charge_struct->mm is added and ->can_attach is now responsible
for pinning and recording the target mm. mem_cgroup_clear_mc() is
updated accordingly. This also simplifies mem_cgroup_move_task().
* mem_cgroup_move_task() is now called from ->post_attach instead of
->attach.

cgroup, cpuset: replace cpuset_post_attach_flush() with cgroup_subsys->post_attach callback
Since e93ad19d0564 ("cpuset: make mm migration asynchronous"), cpuset
kicks off asynchronous NUMA node migration if necessary during task
migration and flushes it from cpuset_post_attach_flush() which is
called at the end of __cgroup_procs_write(). This is to avoid
performing migration with cgroup_threadgroup_rwsem write-locked which
can lead to deadlock through dependency on kworker creation.
memcg has a similar issue with charge moving, so let's convert it to
an official callback rather than the current one-off cpuset specific
function. This patch adds cgroup_subsys->post_attach callback and
makes cpuset register cpuset_post_attach_flush() as its ->post_attach.
The conversion is mostly one-to-one except that the new callback is
called under cgroup_mutex. This is to guarantee that no other
migration operations are started before ->post_attach callbacks are
finished. cgroup_mutex is one of the outermost mutex in the system
and has never been and shouldn't be a problem. We can add specialized
synchronization around __cgroup_procs_write() but I don't think
there's any noticeable benefit.

What happens is the following:

(2) old "none" ac is destroyed
(3) new "cephx" ac is constructed
...
(4) old OSD session (w/ "none" authorizer) is put
ceph_auth_destroy_authorizer(ac, osd->o_auth.authorizer)
osd->o_auth.authorizer in the "none" case is just a bare pointer into
ac, which contains a single static copy for all services. By the time
we get to (4), "none" ac, freed in (2), is long gone. On top of that,
a new vtable installed in (3) points us at ceph_x_destroy_authorizer(),
so we end up trying to destroy a "none" authorizer with a "cephx"
destructor operating on invalid memory!
To fix this, decouple authorizer destruction from ac and do away with
a single static "none" authorizer by making a copy for each OSD or MDS
session. Authorizers themselves are independent of ac and so there is
no reason for destroy_authorizer() to be an ac op. Make it an op on
the authorizer itself by turning ceph_authorizer into a real struct.

toshiba_acpi: Fix regression caused by hotkey enabling value
Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.
This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.

[media] vb2-memops: Fix over allocation of frame vectors
On page unaligned frames, create_framevec forces get_vaddr_frames to
allocate an extra page at the end of the buffer. Under some
circumstances, this leads to -EINVAL on VIDIOC_QBUF.
E.g:
We have vm_a that vm_area that goes from 0x1000 to 0x3000. And a
frame that goes from 0x1800 to 0x2800, i.e. 2 pages.
frame_vector_create will be called with the following params:
get_vaddr_frames(0x1800, 2, write, 1, vec);
get_vaddr will allocate the first page after checking that the memory
0x1800-0x27ff is valid, but it will not allocate the second page because
the range 0x2800-0x37ff is out of the vm_a range. This results in
create_framevec returning -EFAULT

The reason for this, is that when this code has been refactored, some of
the operations have changed their order, and now fileio emulator is not
started.
The reintroduced check to the core is enabled by a quirk flag, that
avoids this check by other subsystems like DVB.

udf: Fix conversion of 'dstring' fields to UTF8
Commit 9293fcfbc1812a22ad5ce1b542eb90c1bbe01be1
("udf: Remove struct ustr as non-needed intermediate storage"),
while getting rid of 'struct ustr', does not take any special care
of 'dstring' fields and effectively use fixed field length instead
of actual string length, encoded in the last byte of the field.
Also, commit 484a10f49387e4386bf2708532e75bf78ffea2cb
("udf: Merge linux specific translation into CS0 conversion function")
introduced checking of the length of the string being converted,
requiring proper alignment to number of bytes constituing each
character.
The UDF volume identifier is represented as a 32-bytes 'dstring',
and needs to be converted from CS0 to UTF8, while mounting UDF
filesystem. The changes in mentioned commits can in some cases
lead to incorrect handling of volume identifier:
- if the actual string in 'dstring' is of maximal length and
does not have zero bytes separating it from dstring encoded
length in last byte, that last byte may be included in conversion,
thus making incorrect resulting string;
- if the identifier is encoded with 2-bytes characters (compression
code is 16), the length of 31 bytes (32 bytes of field length minus
1 byte of compression code), taken as the string length, is reported
as an incorrect (unaligned) length, and the conversion fails, which
in its turn leads to volume mounting failure.
This patch introduces handling of 'dstring' encoded length field
in udf_CS0toUTF8 function, that is used in all and only cases
when 'dstring' fields are converted. Currently these cases are
processing of Volume Identifier and Volume Set Identifier fields.
The function is also renamed to udf_dstrCS0toUTF8 to distinctly
indicate that it handles 'dstring' input.

lockdep: Fix lock_chain::base size
lock_chain::base is used to store an index into the chain_hlocks[]
array, however that array contains more elements than can be indexed
using the u16.
Change the lock_chain structure to use a bitfield to encode the data
it needs and add BUILD_BUG_ON() assertions to check the fields are
wide enough.
Also, for DEBUG_LOCKDEP, assert that we don't run out of elements of
that array; as that would wreck the collision detectoring.

xen/qspinlock: Don't kick CPU if IRQ is not initialized
The following commit:

... moved the initalization of the kicker interrupt until after
native_cpu_up() is called.
However, when using qspinlocks, a CPU may try to kick another CPU that is
spinning (because it has not yet initialized its kicker interrupt), resulting
in the following crash during boot:

To fix this, only send the kick if the target CPU's interrupt has been
initialized. This check isn't racy, because the target is waiting for
the spinlock, so it won't have initialized the interrupt in the
meantime.

- match_name points to the NUL-terminated string "ab".
This function is supposed to accept "var_name" inputs that are not

i2c: exynos5: Fix possible ABBA deadlock by keeping I2C clock prepared
The exynos5 I2C controller driver always prepares and enables a clock
before using it and then disables unprepares it when the clock is not
used anymore.
But this can cause a possible ABBA deadlock in some scenarios since a
driver that uses regmap to access its I2C registers, will first grab
the regmap lock and then the I2C xfer function will grab the prepare
lock when preparing the I2C clock. But since the clock driver also
uses regmap for I2C accesses, preparing a clock will first grab the
prepare lock and then the regmap lock when using the regmap API.
An example of this happens on the Exynos5422 Odroid XU4 board where a
s2mps11 PMIC is used and both the s2mps11 regulators and clk drivers
share the same I2C regmap.
The possible deadlock is reported by the kernel lockdep:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
*** DEADLOCK ***
Fix it by leaving the code prepared on probe and use {en,dis}able in
the I2C transfer function.
This patch is similar to commit 34e81ad5f0b6 ("i2c: s3c2410: fix ABBA
deadlock by keeping clock prepared") that fixes the same bug in other
driver for an I2C controller found in Samsung SoCs.

ARCv2: Enable LOCKDEP
- The asm helpers for calling into irq tracer were missing
- Add calls to above helpers in low level assembly entry code for ARCv2
- irq_save() uses CLRI to disable interrupts and returns the prev interrupt
state (in STATUS32) in a specific encoding (and not the raw value of
STATUS32). This is usable with SETI in irq_restore(). However
save_flags() reads the raw value of STATUS32 which doesn't pair with
irq_save/restore() and thus needs fixing.

sparc/pci: Refactor dev_archdata initialization into pci_init_dev_archdata
The function pcibios_add_device() added by commit d0c31e020057
("sparc/PCI: Fix for panic while enabling SR-IOV") initializes
the dev_archdata by doing a memcpy from the PF. This has the
problem that it erroneously copies the OF device without
explicitly refcounting it.
As David Miller pointed out: "Generally speaking we don't
really support hot-plug for OF probed devices, but if we did
all of the device tree pointers have to be refcounted properly."
To fix this error, and also avoid code duplication, this patch
creates a new helper function, pci_init_dev_archdata(), that
initializes the fields in dev_archdata, and can be invoked
by callers after they have taken the needed refcounts

by all engines in the core, leading to different views of the memory

wrong and might lead to other subtile problems.
Rather than trying to work around this, just disable the linear memory

s390/mm: fix asce_bits handling with dynamic pagetable levels
There is a race with multi-threaded applications between context switch and
pagetable upgrade. In switch_mm() a new user_asce is built from mm->pgd and
mm->context.asce_bits, w/o holding any locks. A concurrent mmap with a
pagetable upgrade on another thread in crst_table_upgrade() could already
have set new asce_bits, but not yet the new mm->pgd. This would result in a
corrupt user_asce in switch_mm(), and eventually in a kernel panic from a
translation exception.
Fix this by storing the complete asce instead of just the asce_bits, which
can then be read atomically from switch_mm(), so that it either sees the
old value or the new value, but no mixture. Both cases are OK. Having the
old value would result in a page fault on access to the higher level memory,
but the fault handler would see the new mm->pgd, if it was a valid access
after the mmap on the other thread has completed. So as worst-case scenario
we would have a page fault loop for the racing thread until the next time
slice.
Also remove dead code and simplify the upgrade/downgrade path, there are no
upgrades from 2 levels, and only downgrades from 3 levels for compat tasks.
There are also no concurrent upgrades, because the mmap_sem is held with
down_write() in do_mmap, so the flush and table checks during upgrade can
be removed.

s390/pci: fix use after free in dma_init
After a failure during registration of the dma_table (because of the
function being in error state) we free its memory but don't reset the
associated pointer to zero.
When we then receive a notification from firmware (about the function
being in error state) we'll try to walk and free the dma_table again.
Fix this by resetting the dma_table pointer. In addition to that make
sure that we free the iommu_bitmap when appropriate.

[media] usbvision: revert commit 588afcc1
Commit 588afcc1c0e4 ("[media] usbvision fix overflow of interfaces
array")' should be reverted, because:
* "!dev->actconfig->interface[ifnum]" won't catch a case where the value
is not NULL but some garbage. This way the system may crash later with
GPF.
* "(ifnum >= USB_MAXINTERFACES)" does not cover all the error
conditions. "ifnum" should be compared to "dev->actconfig->
desc.bNumInterfaces", i.e. compared to the number of "struct
usb_interface" kzalloc()-ed, not to USB_MAXINTERFACES.
* There is a "struct usb_device" leak in this error path, as there is
usb_get_dev(), but no usb_put_dev() on this path.
* There is a bug of the same type several lines below with number of
endpoints. The code is accessing hard-coded second endpoint
("interface->endpoint[1].desc") which may not exist. It would be great
to handle this in the same patch too.
* All the concerns above are resolved by already-accepted commit fa52bd50
("[media] usbvision: fix crash on detecting device with invalid
configuration")
* Mailing list message:

[media] videobuf2-v4l2: Verify planes array in buffer dequeueing
When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer
which will be dequeued is not known until the buffer has been removed from
the queue. The number of planes is specific to a buffer, not to the queue.
This does lead to the situation where multi-plane buffers may be requested
and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument
struct with fewer planes.
__fill_v4l2_buffer() however uses the number of planes from the dequeued
videobuf2 buffer, overwriting kernel memory (the m.planes array allocated
in video_usercopy() in v4l2-ioctl.c) if the user provided fewer
planes than the dequeued buffer had. Oops!

If the system enters S3 during a playback, codec power needs to

this patch the AFG node is set to D3 and codec power is turned
OFF during controller suspend call.
During resume, the codec power is left in ON state if the
playback was in progress while suspending.
Also setting power state for AFG node is optimized. With this the
loop with timeout is removed and codec_read is used instead.

Same panic happened with Intel ixgbe driver also.
SR-IOV code looks for arch specific data while enabling
VFs. When VF device is added, driver probe function makes set
of calls to initialize the pci device. Because the VF device is
added different way than the normal PF device(which happens via
of_create_pci_dev for sparc), some of the arch specific initialization
does not happen for VF device. That causes panic when archdata is
accessed.
To fix this, I have used already defined weak function
pcibios_setup_device to copy archdata from PF to VF.
Also verified the fix.

Suspend/resume callbacks are moved from the i2c dev_pm_ops to
snd_soc_codec_driver. soc_resume_deferred is a delayed work
which may trigger nau8825_set_bias_level. The bias change races
against dev_pm_ops, causing jack detection issues.
soc_resume_deferred ensures bias change and snd_soc_codec_driver
suspend/resume are sequenced correctly.

ASoC: Intel: Skylake: Fix DSP resource de-allocation
In PRE PMD of widget handler DSP resources are allocated after
the creation of DSP pipe and modules and in POST PMD DSP
resources are destroyed.
If there is any failure in pipe or module creation in PRE PMD,
pcm trigger fails and finally POST PMD gets called and DSP
resources are freed, without getting allocated.
Fixes the DSP resource de-allocation by allocating the resource
before creation of pipe and module in PRE PMD and in POST PMD,
free the resources.

The code is actually correct because it checks the dev->of_node
variable first and we know this is NULL here when CONFIG_OF
is disabled, but Russell King noticed that it's broken when
we probe the device using DT, and the properties are absent.
The code already has some checking for incorrect values, and
I keep that checking unchanged here, but add an additional
check for an error returned by the property accessor functions
that now gets handled the same way as incorrect data in the
properties.

net: relax expensive skb_unclone() in iptunnel_handle_offloads()
Locally generated TCP GSO packets having to go through a GRE/SIT/IPIP
tunnel have to go through an expensive skb_unclone()
Reallocating skb->head is a lot of work.
Test should really check if a 'real clone' of the packet was done.
TCP does not care if the original gso_type is changed while the packet
travels in the stack.
This adds skb_header_unclone() which is a variant of skb_clone()
using skb_header_cloned() check instead of skb_cloned().
This variant can probably be used from other points.

Merge branch 'bridge-per-vlan-stats'
Nikolay Aleksandrov says:
====================
bridge: per-vlan stats
This set adds support for bridge per-vlan statistics.
In order to be able to dump statistics for many vlans we need a way to
continue dumping after reaching maximum size, thus patches 01 and 02 extend
the new stats API with a per-device extended link stats attribute and
callback which can save its local state and continue where it left off
afterwards. I considered using the already existing "fill_xstats" callback
but it gets confusing since we need to separate the linkinfo dump from the
new stats api dump and adding a flag/argument to do that just looks messy.
I don't think the rtnl_link_ops size is an issue, so adding these seemed
like the cleaner approach.
Patches 03 and 04 add the stats support and netlink dump support
respectively. The stats accounting is controlled via a bridge option which
is default off, thus the performance impact is kept minimal.
I've tested this set with both old and modified iproute2, kmemleak on and
some traffic stress tests while adding/removing vlans and ports.
v3:
- drop the RCU pvid patch and remove one pointer fetch as requested
- make stats accounting optional with default to off, the option is in the
same cache line as vlan_proto and vlan_enabled, so it is already fetched
before the fast path check thus the performance impact is minimal, this
also allows us to avoid one vlan lookup and return early when using pvid
- rebased and retested
v2:
- Improve the error checking, rename lidx to prividx and save the current
idx user instead of restricting it to one in patch 01
- squash patch 02 into 01 and remove the restriction
- add callback descriptions, improve the size calculation and change the
xstats message structure to have an embedding level per rtnl link type
so we can avoid one call to get the link type (and thus filter on it)
and also each link type can now have any number of private attributes
inside
- fix a problem where the vlan stats are not dumped if the bridge has 0
vlans on it but has vlans on the ports, add bridge link type private
attributes and also add paddings for future extensions to avoid at least
a few netlink attributes and improve struct alignment
- drop the is_skb_forwardable argument constifying patch as it's not
needed anymore, but it's a nice cleanup which I'll send separately

bridge: vlan: learn to count
Add support for per-VLAN Tx/Rx statistics. Every global vlan context gets
allocated a per-cpu stats which is then set in each per-port vlan context
for quick access. The br_allowed_ingress() common function is used to
account for Rx packets and the br_handle_vlan() common function is used
to account for Tx packets. Stats accounting is performed only if the
bridge-wide vlan_stats_enabled option is set either via sysfs or netlink.
A struct hole between vlan_enabled and vlan_proto is used for the new
option so it is in the same cache line. Currently it is binary (on/off)
but it is intentionally restricted to exactly 0 and 1 since other values
will be used in the future for different purposes (e.g. per-port stats).

net: rtnetlink: add linkxstats callbacks and attribute
Add callbacks to calculate the size and fill link extended statistics
which can be split into multiple messages and are dumped via the new
rtnl stats API (RTM_GETSTATS) with the IFLA_STATS_LINK_XSTATS attribute.
Also add that attribute to the idx mask check since it is expected to
be able to save state and resume dumping (e.g. future bridge per-vlan
stats will be dumped via this attribute and callbacks).
Each link type should nest its private attributes under the per-link type
attribute. This allows to have any number of separated private attributes
and to avoid one call to get the dev link type.

Tom Herbert says:
====================
net: Cleanup IPv6 ip tunnels
The IPv6 tunnel code is very different from IPv4 code. There is a lot
of redundancy with the IPv4 code, particularly in the GRE tunneling.
This patch set cleans up the tunnel code to make the IPv6 code look
more like the IPv4 code and use common functions between the two
stacks where possible.
This work should make it easier to maintain and extend the IPv6 ip
tunnels.
Items in this patch set:
- Cleanup IPv6 tunnel receive path (ip6_tnl_rcv). Includes using
gro_cells and exporting ip6_tnl_rcv so the ip6_gre can call it
- Move GRE functions to common header file (tx functions) or
gre_demux.c (rx functions like gre_parse_header)
- Call common GRE functions from IPv6 GRE
- Create ip6_tnl_xmit (to be like ip_tunnel_xmit)
Tested:
Ran super_netperf tests for TCP_RR and TCP_STREAM for:
- IPv4 over gre, gretap, gre6, gre6tap
- IPv6 over gre, gretap, gre6, gre6tap
- ipip
- ip6ip6

====================
net: make TCP preemptible
Most of TCP stack assumed it was running from BH handler.
This is great for most things, as TCP behavior is very sensitive
to scheduling artifacts.
However, the prequeue and backlog processing are problematic,
as they need to be flushed with BH being blocked.
To cope with modern needs, TCP sockets have big sk_rcvbuf values,
in the order of 16 MB, and soon 32 MB.
This means that backlog can hold thousands of packets, and things
like TCP coalescing or collapsing on this amount of packets can
lead to insane latency spikes, since BH are blocked for too long.
It is time to make UDP/TCP stacks preemptible.
Note that fast path still runs from BH handler.
v2: Added "tcp: make tcp_sendmsg() aware of socket backlog"
to reduce latency problems of large sends.
v3: Fixed a typo in tcp_cdg.c

tcp: make tcp_sendmsg() aware of socket backlog
Large sendmsg()/write() hold socket lock for the duration of the call,
unless sk->sk_sndbuf limit is hit. This is bad because incoming packets
are parked into socket backlog for a long time.
Critical decisions like fast retransmit might be delayed.
Receivers have to maintain a big out of order queue with additional cpu
overhead, and also possible stalls in TX once windows are full.
Bidirectional flows are particularly hurt since the backlog can become
quite big if the copy from user space triggers IO (page faults)
Some applications learnt to use sendmsg() (or sendmmsg()) with small
chunks to avoid this issue.
Kernel should know better, right ?
Add a generic sk_flush_backlog() helper and use it right
before a new skb is allocated. Typically we put 64KB of payload
per skb (unless MSG_EOR is requested) and checking socket backlog
every 64KB gives good results.
As a matter of fact, tests with TSO/GSO disabled give very nice
results, as we manage to keep a small write queue and smaller
perceived rtt.
Note that sk_flush_backlog() maintains socket ownership,
so is not equivalent to a {release_sock(sk); lock_sock(sk);},
to ensure implicit atomicity rules that sendmsg() was
giving to (possibly buggy) applications.
In this simple implementation, I chose to not call tcp_release_cb(),
but we might consider this later.

net: do not block BH while processing socket backlog
Socket backlog processing is a major latency source.
With current TCP socket sk_rcvbuf limits, I have sampled __release_sock()
holding cpu for more than 5 ms, and packets being dropped by the NIC
once ring buffer is filled.
All users are now ready to be called from process context,
we can unblock BH and let interrupts be serviced faster.
cond_resched_softirq() could be removed, as it has no more user.

====================
40GbE Intel Wired LAN Driver Updates 2016-05-01
This series contains updates to i40e and i40evf.
The theme of this series is code reduction, with several code cleanups in
this series. Starting with Neerav's removal of the code that implemented
the HMC AQ APIs and calls, since they are now obsolete and not supported
by firmware.
Anjali changes the default of VFs to make sure they are not trusted or
privileged until its explicitly set for trust through the new NDO op
interface. Also limited the number of MAC and VLAN addresses a VF can
add if it is untrusted/privileged.
Carolyn syncs the VF code for the changes made to the PF for the RSS
hash tuple settings, which ends up cleaning up much of the existing code.
Jesse cleans up compiler warnings which were found with gcc's W=2 option.
Then removed duplicate code, especially since only one copy was actually
being used.
Jacob addresses an issue which was found when testing GCC 6's which
happens to produce new warnings when you left shift a signed value
beyond the storage sizeof the type. The converts i40e & i40evf to use
the BIT() macro more consistently.
Alex actually bucks the trend of code removal by adding support for
both drivers to use GSO_PARTIAL so that segmentation of frames with
checksums enabled in outer headers is supported. Fortunately it does
not take much to add this support!

Dave Miller pointed out that fb586f25300f ("sctp: delay calls to
sk_data_ready() as much as possible") may insert latency specially if
the receiving application is running on another CPU and that it would be
better if we signalled as early as possible.
This patch thus basically inverts the logic on fb586f25300f and signals
it as early as possible, similar to what we had before.

mdio_bus: Fix MDIO bus scanning in __mdiobus_register()
Since commit b74766a0a0fe ("phylib: don't return NULL
from get_phy_device()") in linux-next, phy_get_device() will return
ERR_PTR(-ENODEV) instead of NULL if the PHY device ID is all ones.
This causes problem with stmmac driver and likely some other drivers
which call mdiobus_register(). I triggered this bug on SoCFPGA MCVEVK
board with linux-next 20160427 and 20160428. In case of the stmmac, if
there is no PHY node specified in the DT for the stmmac block, the stmmac
driver ( drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c function
stmmac_mdio_register() ) will call mdiobus_register() , which will
register the MDIO bus and probe for the PHY.
The mdiobus_register() resp. __mdiobus_register() iterates over all of
the addresses on the MDIO bus and calls mdiobus_scan() for each of them,
which invokes get_phy_device(). Before the aforementioned patch, the
mdiobus_scan() would return NULL if no PHY was found on a given address
and mdiobus_register() would continue and try the next PHY address. Now,
mdiobus_scan() returns ERR_PTR(-ENODEV), which is caught by the
'if (IS_ERR(phydev))' condition and the loop exits immediately if the
PHY address does not contain PHY.
Repair this by explicitly checking for the ERR_PTR(-ENODEV) and if this
error comes around, continue with the next PHY address.

i40e/i40evf: Add support for GSO partial with UDP_TUNNEL_CSUM and GRE_CSUM
This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers. As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.
The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.

i40e/i40evf: fix I40E_MASK signed shift overflow warnings
GCC 6 has a new warning which will display when you attempt to left
shift a signed value beyond the storage size of the type. I40E_MASK
generates a mask value for 32bit registers. Properly typecast the mask
value and place the values in parenthesis to prevent macro expansion
issues.

Add a check whether the 'struct device_node' pointer passed to

Rationale for doing this are cases where an Ethernet MAC provides a MDIO
bus controller and node, and an additional Ethernet MAC might be
connecting its PHY/switches to that first MDIO bus controller, while
still embedding one internally which is therefore marked as "disabled".
Instead of sprinkling checks like these in callers of

Merge branch 'mlx5-aRFS'
Saeed Mahameed says:
====================
Mellanox 100G mlx5 ethernet aRFS support
This series adds accelerated RFS support for the mlx5e driver.
I have added one patch non-related to aRFS that fixes the rtnl_lock
warning mlx5 driver been getting since b7aade15485a ('vxlan: break dependency with netdev drivers')
aRFS support in details:
A direct TIR per RQ is now required in order to have the essential building blocks
for aRFS. Today the driver has one direct TIR that forwards traffic to RQ[0] (core 0),
and one indirect TIR for RSS indirection table. For that we've added one direct TIR
per RQ, e.g.: TIR[i] -> RQ[i] (core i).
Publicize Modify flow rule destination and reveal it in flow steering API, to have the
ability to dynamically modify the destination TIR(core) for aRFS rules from the
ethernet driver.
Initializing CPU reverse mapping to notify upper layer on internal receive queue cpu
mappings.
Some design refactoring for mlx5e ethernet driver flow tables and flow steering API.
Now the caller of create_flow_table can choose the level of the flow table, this way
we will create the mlx5e flow tables in a reversed order and connect them as we go,
we create flow table[i+1] before flow table[i] to be able to set flow table[i + 1] as
a destination of flow table[i] once flow table[i] is created.
also we have split the main flow table in the following manner:
- From before: RX packet had to visit two flow tables until it is delivered to its receive queue:
RX packet -> vlan filter flow table -> main flow table.
> vlan filter will check the packet vlan field is allowed.
> main flow will check if the dest mac is allowed and will check the l3/l4 headers to
retrieve the RSS hash for steering the packet into its final receive queue.
- Now main flow table is split into l2 dst mac steering table and ttc (traffic type classifier) table:
RX packet -> vlan filter -> l2 table -> ttc table
> vlan filter - same as before
> L2 filter - filter packets according their destination mac address
> ttc table - classify packet headers for RSS steering
- L3/L4 classification rules to steer the packet according to thier headers hash
- in case of none of the rules applies the packet is steered to RQ[0]
After the above refactoring all left to-do is to create aRFS flow table which will manage
aRFS steering rules to forward traffic to the desired RQ (core) and just connect the ttc
table rules destinations to aRFS flow table.
aRFS flow table in case of a miss will deliver the traffic to the core where the original
ttc hash would have chosen.
TTC table is not initialized and enabled until the user explicitly asks to, i.e. setting the NETIF_F_NTUPLE
to ON. This way there is no need for ttc table to forward traffic to aRFS table unless required.
When setting back to OFF aRFS flow table is disabled and disconnected.

net/mlx5e: Create aRFS flow tables
Create the following four flow tables for aRFS usage:

2. IPv6 TCP - filtering 4-tuple of IPv6 TCP packets.
3. IPv4 UDP - filtering 4-tuple of IPv4 UDP packets.
4. IPv6 UDP - filtering 4-tuple of IPv6 UDP packets.
Each flow table has two flow groups: one for the 4-tuple
filtering (full match) and the other contains * rule for miss rule.
Full match rule means a hit for aRFS and packet will be forwarded
to the dedicated RQ/Core, miss rule packets will be forwarded to
default RSS hashing.

net/mlx5e: Split the main flow steering table
Currently, the main flow table is used for two purposes:
One is to do mac filtering and the other is to classify
the packet l3-l4 header in order to steer the packet to
the right RSS TIR.
This design is very complex, for each configured mac address we
have to add eleven rules (rule for each traffic type), the same if the
device is put to promiscuous/allmulti mode.
This scheme isn't scalable for future features like aRFS.
In order to simplify it, the main flow table is split to two flow
tables:
1. l2 table - filter the packet dmac address, if there is a match
we forward to the ttc flow table.
2. TTC (Traffic Type Classifier) table - classify the traffic
type of the packet and steer the packet to the right TIR.
In this new design, when new mac address is added, the driver adds
only one flow rule instead of eleven.

Merge branch 'ppp-rtnetlink'
Guillaume Nault says:
====================
ppp: add rtnetlink support
PPP devices lack the ability to be customised at creation time. In
particular they can't be created in a given netns or with a particular
name. Moving or renaming the device after creation is possible, but
creates undesirable transient effects on servers where PPP devices are
constantly created and removed, as users connect and disconnect.
Implementing rtnetlink support solves this problem.
The rtnetlink handlers implemented in this series are minimal, and can
only replace the PPPIOCNEWUNIT ioctl. The rest of PPP ioctls remains
necessary for any other operation on channels and units.
It is perfectly possible to mix PPP devices created by rtnl
and by ioctl(PPPIOCNEWUNIT). Devices will behave in the same way.
mutex_trylock() is used to resolve the locking issue wrt. locking
dependency between rtnl_lock() and ppp_mutex (see ppp_nl_newlink() in
patch #2).
A user visible difference brought by this series is that old PPP
interfaces (those created with ioctl(PPPIOCNEWUNIT)), can now be
removed by "ip link del", just like new rtnl based PPP devices.
Changes since v3:
- Rebase on net-next.
- Not an RFC anymore.
Changes since v2:
- Define ->rtnl_link_ops for ioctl based PPP devices, so they can
handle rtnl messages just like rtnl based ones (suggested by
Stephen Hemminger).
- Move back to original lock ordering between ppp_mutex and rtnl_lock
to simplify patch series. Handle lock inversion issue using
mutex_trylock() (suggested by Stephen Hemminger).
- Do file descriptor lookup directly in ppp_nl_newlink(), to simplify
ppp_dev_configure().
Changes since v1:
- Rebase on net-next.
- Invert locking order wrt. ppp_mutex and rtnl_lock and protect
file->private_data with ppp_mutex.

ppp: add rtnetlink device creation support
Define PPP device handler for use with rtnetlink.
The only PPP specific attribute is IFLA_PPP_DEV_FD. It is mandatory and
contains the file descriptor of the associated /dev/ppp instance (the
file descriptor which would have been used for ioctl(PPPIOCNEWUNIT) in
the ioctl-based API). The PPP device is removed when this file
descriptor is released (same behaviour as with ioctl based PPP
devices).
PPP devices created with the rtnetlink API behave like the ones created
with ioctl(PPPIOCNEWUNIT). In particular existing ioctls work the same
way, no matter how the PPP device was created.
The rtnl callbacks are also assigned to ioctl based PPP devices. This
way, rtnl messages have the same effect on any PPP devices.
The immediate effect is that all PPP devices, even ioctl-based
ones, can now be removed with "ip link del".
A minor difference still exists between ioctl and rtnl based PPP
interfaces: in the device name, the number following the "ppp" prefix
corresponds to the PPP unit number for ioctl based devices, while it is
just an unrelated incrementing index for rtnl ones.

ppp: define reusable device creation functions
Move PPP device initialisation and registration out of
ppp_create_interface().
This prepares code for device registration with rtnetlink.
While there, simplify the prototype of ppp_create_interface():
* Since ppp_dev_configure() takes care of setting file->private_data,
there's no need to return a ppp structure to ppp_unattached_ioctl()
anymore.
* The unit parameter is made read/write so that ppp_create_interface()
can tell which unit number has been assigned.

vxlan: fix initialization with custom link parameters
Commit 0c867c9bf84c ("vxlan: move Ethernet initialization to a separate
function") changed initialization order and as an unintended result, when the
user specifies additional link parameters (such as IFLA_ADDRESS) while
creating vxlan interface, those are overwritten by vxlan_ether_setup later.
It's necessary to call ether_setup from withing the ->setup callback. That
way, the correct parameters are set by rtnl_create_link later. This is done
also for VXLAN-GPE, as we don't know the interface type yet at that point,
and changed to the correct interface type later.

samples/bpf: add back functionality to redefine LLC command
It is practical to be-able-to redefine the location of the LLVM
command 'llc', because not all distros have a LLVM version with bpf

default LLVM version.

PATH, rather than a hardcoded value").
Add this features back. Note that it is possible to redefine the LLC
on the make command like:
make samples/bpf/ LLC=~/git/llvm/build/bin/llc

net: dsa: Provide CPU port statistics to master netdev
This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also
include switch-side statistics, which is useful for debugging purposes,
when the switch is not properly connected to the Ethernet MAC (duplex
mismatch, (RG)MII electrical issues etc.).
We accomplish this by retaining the original copy of the master netdev's
ethtool_ops, and just overload the 3 operations we care about:
get_sset_count, get_strings and get_ethtool_stats so as to intercept
these calls and call into the original master_netdev ethtool_ops, plus
our own.
We take this approach as opposed to providing a set of DSA helper
functions that would retrive the CPU port's statistics, because the
entire purpose of DSA is to allow unmodified Ethernet MAC drivers to be
used as CPU conduit interfaces, therefore, statistics overlay in such
drivers would simply not scale.
The new ethtool -S <iface> output would therefore look like this now:
<iface> statistics
p<2 digits cpu port number>_<switch MIB counter names>

tcp: give prequeue mode some care
TCP prequeue goal is to defer processing of incoming packets
to user space thread currently blocked in a recvmsg() system call.
Intent is to spend less time processing these packets on behalf
of softirq handler, as softirq handler is unfair to normal process
scheduler decisions, as it might interrupt threads that do not
even use networking.
Current prequeue implementation has following issues :
1) It only checks size of the prequeue against sk_rcvbuf
It was fine 15 years ago when sk_rcvbuf was in the 64KB vicinity.
But we now have ~8MB values to cope with modern networking needs.
We have to add sk_rmem_alloc in the equation, since out of order
packets can definitely use up to sk_rcvbuf memory themselves.
2) Even with a fixed memory truesize check, prequeue can be filled
by thousands of packets. When prequeue needs to be flushed, either
from sofirq context (in tcp_prequeue() or timer code), or process
context (in tcp_prequeue_process()), this adds a latency spike
which is often not desirable.
I added a fixed limit of 32 packets, as this translated to a max
flush time of 60 us on my test hosts.
Also note that all packets in prequeue are not accounted for tcp_mem,
since they are not charged against sk_forward_alloc at this point.
This is probably not a big deal.
Note that this might increase LINUX_MIB_TCPPREQUEUEDROPPED counts,
which is misnamed, as packets are not dropped at all, but rather pushed
to the stack (where they can be either consumed or dropped)

tuntap: calculate rps hash only when needed
There's no need to calculate rps hash if it was not enabled. So this
patch export rps_needed and check it before trying to get rps
hash. Tests (using pktgen to inject packets to guest) shows this can
improve pps about 13% (when rps is disabled).

Merge branch 'tcp-eor'
Martin KaFai Lau says:
====================
tcp: Make use of MSG_EOR in tcp_sendmsg
v4:
~ Do not set eor bit in do_tcp_sendpages() since there is
no way to pass MSG_EOR from the userland now.
~ Avoid rmw by testing MSG_EOR first in tcp_sendmsg().
~ Move TCP_SKB_CB(skb)->eor test to a new helper
tcp_skb_can_collapse_to() (suggested by Soheil).
~ Add some packetdrill tests.
v3:
~ Separate EOR marking from the SKBTX_ANY_TSTAMP logic.
~ Move the eor bit test back to the loop in tcp_sendmsg and
tcp_sendpage because there could be >1 threads doing
sendmsg.
~ Thanks to Eric Dumazet's suggestions on v2.
~ The TCP timestamp bug fixes are separated into other threads.
v2:
~ Rework based on the recent work
"add TX timestamping via cmsg" by
Soheil Hassas Yeganeh <soheil.kdev(a)gmail.com>
~ This version takes the MSG_EOR bit as a signal of
end-of-response-message and leave the selective
timestamping job to the cmsg
~ Changes based on the v1 feedback (like avoid
unlikely check in a loop and adding tcp_sendpage
support)
~ The first 3 patches are bug fixes. The fixes in this
series depend on the newly introduced txstamp_ack in
net-next. I will make relevant patches against net after
getting some feedback.
~ The test results are based on the recently posted net fix:
"tcp: Fix SOF_TIMESTAMPING_TX_ACK when handling dup acks"
One potential use case is to use MSG_EOR with
SOF_TIMESTAMPING_TX_ACK to get a more accurate
TCP ack timestamping on application protocol with
multiple outgoing response messages (e.g. HTTP2).
One of our use case is at the webserver. The webserver tracks
the HTTP2 response latency by measuring when the webserver sends
the first byte to the socket till the TCP ACK of the last byte
is received. In the cases where we don't have client side
measurement, measuring from the server side is the only option.
In the cases we have the client side measurement, the server side
data can also be used to justify/cross-check-with the client
side data.

tcp: Make use of MSG_EOR in tcp_sendmsg
This patch adds an eor bit to the TCP_SKB_CB. When MSG_EOR
is passed to tcp_sendmsg, the eor bit will be set at the skb
containing the last byte of the userland's msg. The eor bit
will prevent data from appending to that skb in the future.
The change in do_tcp_sendpages is to honor the eor set
during the previous tcp_sendmsg(MSG_EOR) call.
This patch handles the tcp_sendmsg case. The followup patches
will handle other skb coalescing and fragment cases.
One potential use case is to use MSG_EOR with
SOF_TIMESTAMPING_TX_ACK to get a more accurate
TCP ack timestamping on application protocol with
multiple outgoing response messages (e.g. HTTP2).

tcp: remove SKBTX_ACK_TSTAMP since it is redundant
The SKBTX_ACK_TSTAMP flag is set in skb_shinfo->tx_flags when
the timestamp of the TCP acknowledgement should be reported on
error queue. Since accessing skb_shinfo is likely to incur a
cache-line miss at the time of receiving the ack, the
txstamp_ack bit was added in tcp_skb_cb, which is set iff
the SKBTX_ACK_TSTAMP flag is set for an skb. This makes
SKBTX_ACK_TSTAMP flag redundant.
Remove the SKBTX_ACK_TSTAMP and instead use the txstamp_ack bit
everywhere.
Note that this frees one bit in shinfo->tx_flags.

tcp: remove an unnecessary check in tcp_tx_timestamp
Remove the redundant check for sk->sk_tsflags in tcp_tx_timestamp.
tcp_tx_timestamp() receives the tsflags as a parameter. As a
result the "sk->sk_tsflags || tsflags" is redundant, since
tsflags already includes sk->sk_tsflags plus overrides from
control messages.

net: snmp: fix 64bit stats on 32bit arches
I accidentally replaced BH disabling by preemption disabling
in SNMP_ADD_STATS64() and SNMP_UPD_PO_STATS64() on 32bit builds.
For 64bit stats on 32bit arch, we really need to disable BH,
since the "struct u64_stats_sync syncp" might be manipulated
both from process and BH contexts.

net: snmp: kill various STATS_USER() helpers
In the old days (before linux-3.0), SNMP counters were duplicated,
one for user context, and one for BH context.
After commit 8f0ea0fe3a03 ("snmp: reduce percpu needs by 50%")
we have a single copy, and what really matters is preemption being
enabled or disabled, since we use this_cpu_inc() or __this_cpu_inc()
respectively.
We therefore kill SNMP_INC_STATS_USER(), SNMP_ADD_STATS_USER(),
NET_INC_STATS_USER(), NET_ADD_STATS_USER(), SCTP_INC_STATS_USER(),
SNMP_INC_STATS64_USER(), SNMP_ADD_STATS64_USER(), TCP_ADD_STATS_USER(),
UDP_INC_STATS_USER(), UDP6_INC_STATS_USER(), and XFRM_INC_STATS_USER()
Following patches will rename __BH helpers to make clear their
usage is not tied to BH being disabled.

Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2016-04-27
This series contains updates to i40e and i40evf.
Alex Duyck cleans up the feature flags since they are becoming pretty
"massive", the primary change being that we now build our features list
around hw_encap_features. Added support for IPIP and SIT offloads,
which should improvement in throughput for IPIP and SIT tunnels with
the offload enabled.
Mitch adds support for configuring RSS on behalf of the VFs, which removes
the burden of dealing with different hardware interfaces from the VF
drivers and improves future compatibility. Fix to ensure that we do not
panic by checking that the vsi_res pointer is valid before dereferencing
it, after which we can drink beer and eat peanuts.
Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation
for more cloud filter work. Added flexibility to the nvmupdate
facility by adding the ability to specify an AQ event opcode to wait on
after Exec_AQ request.
Michal adds device capability which defines if an update is available and
if a security check is needed during the update process.
Kamil just adds a device id to support X722 QSFP+ device.
Greg fixes an issue where a mirror rule ID may be zero, so do not return
invalid parameter when the user passes in a zero for a rule ID. Adds
support to steer packets to VSIs by VLAN tag alone while being in
promiscuous mode for multicast and unicast MAC addresses.
Jesse fixes the driver from offloading the VLAN tag into the skb any
time there was a VLAN tag and the hardware stripping was enabled, to
making sure it is enabled before put_tag.
v2: Dropped patch 8 ("i40e: Allow user to change input set mask for flow
director") while Kiran reworks a more generalized solution based
on feedback from David Miller.

net-rfs: fix false sharing accessing sd->input_queue_head
sd->input_queue_head is incremented for each processed packet
in process_backlog(), and read from other cpus performing
Out Of Order avoidance in get_rps_cpu()
Moving this field in a separate cache line keeps it mostly
hot for the cpu in process_backlog(), as other cpus will
only read it.
In a stress test, process_backlog() was consuming 6.80 % of cpu cycles,
and the patch reduced the cost to 0.65 %

net: w5100: support W5500
This adds support for W5500 chip.
W5500 has similar register and memory organization with W5100 and W5200.
There are a few important differences listed below but it is still
possible to share common code with W5100 and W5200.
* W5500 register and memory are organized by multiple blocks. Each one
is selected by 16bits offset address and 5bits block select bits.
But the existing register access operations take u16 address. This change
extends the addess by u32 address and put offset address to lower 16bits
and block select bits to upper 16bits.
This change also adds the offset addresses for socket register and TX/RX
memory blocks to the driver private data structure in order to reduce
conditional switches for each chip.
* W5500 has the different register offset for socket interrupt mask
register. Newly added internal functions w5100_enable_intr() and
w5100_disable_intr() take care of the diffrence.
* W5500 has the different register offset for retry time-value register.
But this register is only used to verify that the reset value is correctly
read at initialization. So move the verification to w5100_hw_reset()
which already does different things for different chips.

4c9bcd117918b ("net: Fix nexthop lookups")).

sh_eth: rename ARSTR register bit
The Renesas RZ/A1H manual names the software reset bit in the software reset
register (ARSTR) ARST which makes a bit more sense than the ARSTR_ARSTR name
used now by the driver -- rename the latter to ARSTR_ARST.

sh_eth: use EDMR_SRST_GETHER in sh_eth_check_reset()
sh_eth_check_reset() uses a bare number where EDMR_SRST_GETHER would fit,
i.e. the receive/trasmit software reset bits that comprise EDMR_SRST_GETHER
read as 1 while the corresponding reset is in progress and thus, when both
are 0, the reset is complete.

====================
Mellanox 100G extending mlx5 ethtool support
Changes from V0:
- Dropped: net/mlx5e: Disable link up on INIT HCA command
Due to Ido's and Or's requests we will submit this patch to net and will need it for -stable.
- Rebased to: 11afbff86168 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next")
This series is centralized around extending and improving mlx5 ethernet driver ethtool
support. We've done some code refactoring for ethtool statistics reporting, making it
more scalable and robust, now each reported ethtool counter belongs to a group and has
its own descriptor within that group, the descriptor holds the counter name and offset
in memory in that group memory block.
Added new counters:
- Reporting more error and drop counter in ifconig/ip tool.
- Per priority pause and traffic counter in ethtool.
- link down events counter in ethtool.
Set features handling was also refactored a little bit to be more resilient and generic,
now setting more than one feature will not stop on the first failed one, but instead
it will try to continue setting others. We made it generic to make it simpler for adding
more features support, it is now done easily by only introducing a handler function of
the new supported netdev feature, and let the generic handler do the job.
New netdev features and ethtool support:
- Netdev feature RXALL, set on/off FCS check offload.
- Netdev feature HW_VLAN_CTAG_RX, set on/off rx-vlan stripping offload.
- Ethtool interface identify.
- Ethtool dump module EEPROM.

Now as rx-vlan offload can be disabled, packets can be received
with vlan tag not stripped, which means is_first_ethertype_ip will
return false, for that we need to check if the hardware reported
csum OK so we will report CHECKSUM_UNNECESSARY for those packets.

net/mlx5e: Improve set features ndo resiliency
In current mlx5e ndo_set_features implementation, setting some features
can success while others can fail. Today, we return one error code which
doesn't reflect the current features status of the netdev at the end of
the ndo callback.
Set netdev->features with features which were successfully set in order
to keep the current status in case of failure. For this purpose, define
new Macro to set/unset specific feature in netdev->features.
This patch introduces a mechanism that uses feature handlers for each
feature.
Set features will call a generic handler, which will then call a specific
handler in his turn and update netdev->features according to it's return
value. Each specific handler is responsible to perform driver specific
actions, and updating params if needed.

net/mlx5e: Statistics handling refactoring
Redesign ethtool statistics handling and reporting in the driver:
1. Move counters to a separate file (en_stats.h).
2. Remove unnecessary dependencies between stats and strings.
3. Use counter descriptors which hold a name and offset for each counter,
and will be used to decide which counters will be exposed.
For example when adding a new software counter to ethtool, instead of:
1. Add to stats struct.
2. Add to strings struct in the same order.
3. Change macro defining number of software counters.
The only thing needed is to link the new counter to a counter descriptor.
VPort counters are a set of hardware traffic counters created automatically
for each virtual port opened.
PPort counters are a set of counters describing per physical port
performance statistics.
These counters are gathered from hardware register and divided to groups
according to different protocols.

====================
net: core: remove TX_LOCKED support
Not that many users left, lets kill it.
TX_LOCKED was meant to be used by LLTX drivers when spin_trylock()
failed. Stack then re-queued if collisions happened on different
cpus or free'd the skb to prevent deadlocks.
Most of the driver removal patches fall into one of three categories:
1. remove the driver-private tx lock (and LLTX flag), or...
2. convert spin_trylock to plain spin_lock, or...
3. convert TX_LOCKED to free+TX_OK
Patches are grouped by these categories, last patch is the actual removal.
All driver changes were compile tested only with exception of atl1e.

If macvlan_common_newlink fails in register_netdevice after macvlan_init
then it decrements port->count twice, first in macvlan_uninit (from
register_netdevice or rollback_registered) and then again in
macvlan_common_newlink.
A similar problem may exist in the ipvlan driver.
This patch consolidates modifications to port->count into macvlan_init
and macvlan_uninit (thanks to Eric Biederman for suggesting this approach).
v3: remove macvtap specific bits.

cxgb4: Don't assume FW_PORT_CMD reply is always port info msg
The firmware can send a set of asynchronous replies through FW_PORT_CMD
with DCBX information when that's negotiated with the Link Peer. The old
code always assumed that a FW_PORT_CMD reply was always a Get Port

the Get Port Information messages and throws a warning if we don't

i40evf: Allow PF driver to configure RSS
If the PF driver reports proper support, allow the PF driver to
configure RSS on the behalf of the VF driver. This will allow for RSS
support on future hardware without changes to the VF driver.
Unfortunately, the old RSS code still needs to stay as the driver needs
to be compatible with PF drivers that don't support this interface. But
this change still simplifies the data structures a bunch and makes this
code simpler to read and maintain.

====================
netlink: align attributes when needed (patchset #3)
This is the continuation (series #3) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.
It's the last patchset from what I've seen.
The last user of nla_put_u64() is block/drbd. This module does not use
standard netlink API (see all the stuff in include/linux/genl_magic_struct.h
and include/linux/genl_magic_func.h). I didn't modify it because it's seems
hard to do it whithout testing and fully understanding the context (for
example, why include/linux/drbd_genl.h is not part of uapi?).
Any thoughts?

i40e/i40evf: Clean up feature flags
The feature flags list for i40e and i40evf is beginning to become pretty
massive. I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.
The primary change here is that we now build our features list around
hw_encap_features. After that we assign that to vlan_features,
hw_features, and finally map that onto features. In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC. However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.
For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so
disabling it is just a matter of ignoring the result from the hardware.

iwlwifi: fix fw version reading for DVM devices
In commit 97f95c93c8ed ("iwlwifi: remove support for fw older than
-16.ucode") we accidentally changed the fw version reading code for
DVM devices. The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore. But DVM devices still use the old FW API.
Fix that by bringing the code back in.

mwifiex: fix loop timeout in mwifiex_prog_fw_w_helper()
USB8XXX_FW_MAX_RETRY is 3. We were using a post-op loop
"while (retries--) {" but then the lines after that assume the loop
exits with retries set to zero.
I've fixed this by changing to a pre-op loop. I started with retries
set to 4 instead of 3 so that we still go through the loop the same
number of times.

with 64-bit timekeeping variables.
The patch also fixes the debug printf specifier to avoid the

Tom Herbert says:
====================
ila: Support for checksum neutral translations
This patch set updates ILA to support draft-herbert-nvo3-ila-02. The
primary addition is support checksum neutral ILA translation.
This allows address to be performed and still keep any transport
layer checksums that include the addresses in their pseudo header to
still be correct without the translator needing to parse L4.
Other items are:
- Structures for ILA addresses, identifiers, locators
- Disallow translation on non-ILA addresses (check by
type in identifier).
- Change xlat (nf_input) to translates solely based
on matching locators not identifiers (since identifiers
are not obfuscated by checksum neutral).
- Side effect if above is that multiple ILA domains are
supported. Each local locator can map to a different
SIR address (ILA domain), and each domain defines its
own identifier space.
Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better
than previously since we are not longer parsing L4 for checksum
handling. I amd seeing about 1% performance overhead. Also ran
TCP_STREAM and tested non-ILA address (type=0) are not translated.

ila: add checksum neutral ILA translations
Support checksum neutral ILA as described in the ILA draft. The low
order 16 bits of the identifier are used to contain the checksum
adjustment value.
The csum-mode parameter is added to described checksum processing. There
are three values:
- adjust transport checksum (previous behavior)
- do checksum neutral mapping
- do nothing
On output the csum-mode in the ila_params is checked and acted on. If
mode is checksum neutral mapping then to mapping and set C-bit.
On input, C-bit is checked. If it is set checksum-netural mapping is
done (regardless of csum-mode in ila params) and C-bit will be cleared.
If it is not set then action in csum-mode is taken.

ila: xlat changes
Change model of xlat to be used only for input where lookup is done on
the locator part of an address (comparing to locator_match as key
in rhashtable). This is needed for checksum neutral translation
which obfuscates the low order 16 bits of the identifier. It also
permits hosts to be in muliple ILA domains (each locator can map
to a different SIR address). A check is also added to disallow
translating non-ILA addresses (check of type in identifier).

In ILA lwt don't allow user to set a translation for a non-ILA

net: hns: separate debug dsaf device from service dsaf device
There are two kinds of dsaf device in hns, one is for service ports,
contains crossbar in it, can work under different mode. Another is for
debug port, only can work under "single-port" mode. The current code only
declared a dsaf device for both service ports and debug ports. This patch
separate it to three platform devices.

Bluetooth: 6lowpan: Fix memory corruption of ipv6 destination address
The memcpy of ipv6 header destination address to the skb control block
(sbk->cb) in header_create() results in currupted memory when bt_xmit()
is issued. The skb->cb is "released" in the return of header_create()
making room for lower layer to minipulate the skb->cb.
The value retrieved in bt_xmit is not persistent across header creation
and sending, and the lower layer will overwrite portions of skb->cb,
making the copied destination address wrong.
The memory corruption will lead to non-working multicast as the first 4
bytes of the copied destination address is replaced by a value that
resolves into a non-multicast prefix.
This fix removes the dependency on the skb control block between header
creation and send, by moving the destination address memcpy to the send
function path (setup_create, which is called from bt_xmit).

====================
pskb_extract() helper function.
This patchset follows up on the discussion in
https://www.mail-archive.com/netdev@vger.kernel.org/msg105090.html
For RDS-TCP, we have to deal with the full gamut of
nonlinear sk_buffs, including all the frag_list variants.
Also, the parent skb has to remain unchanged, while the clone
is queued for Rx on the PF_RDS socket.
Patch 1 of this patchset adds a pskb_extract() function that
does all this without the redundant memcpy's in pskb_expand_head()
and __pskb_pull_tail().

skbuff: Add pskb_extract() helper function
A pattern of skb usage seen in modules such as RDS-TCP is to
extract `to_copy' bytes from the received TCP segment, starting
at some offset `off' into a new skb `clone'. This is done in
the ->data_ready callback, where the clone skb is queued up for rx on
the PF_RDS socket, while the parent TCP segment is returned unchanged
back to the TCP engine.
The existing code uses the sequence
clone = skb_clone(..);
pskb_pull(clone, off, ..);
pskb_trim(clone, to_copy, ..);
with the intention of discarding the first `off' bytes. However,
skb_clone() + pskb_pull() implies pksb_expand_head(), which ends
up doing a redundant memcpy of bytes that will then get discarded
in __pskb_pull_tail().
To avoid this inefficiency, this commit adds pskb_extract() that
creates the clone, and memcpy's only the relevant header/frag/frag_list
to the start of `clone'. pskb_trim() is then invoked to trim clone
down to the requested to_copy bytes.

carrying function definitions to include in given,

codel: split into multiple files
It was impossible to include codel.h for the
purpose of having access to codel_params or
codel_vars structure definitions and using them
for embedding in other more complex structures.
This splits allows codel.h itself to be treated
like any other header file while codel_qdisc.h and
codel_impl.h contain function definitions with
logic that was previously in codel.h.
This copies over copyrights and doesn't involve
code changes other than adding a few additional
include directives to net/sched/sch*codel.c.

route: move lwtunnel state to a single place
Commit 751a587ac9f9 ("route: fix breakage after moving lwtunnel state")
moved lwtstate to the end of dst_entry for 32bit archs. This makes it share
the cacheline with __refcnt which had an unkown effect on performance. For
this reason, the pointer was kept in place for 64bit archs.
However, later performance measurements showed this is of no concern. It
turns out that every performance sensitive path that accesses lwtstate
accesses also struct rtable or struct rt6_info which share the same cache
line.
Thus, to get rid of a few #ifdefs, move the field to the end of the struct
also for 64bit.

user APIs that may change the configuration.
Instead, let the core-module [qed] decide whether an interface can change
the configuration by supporting a new API function. We also revise the
current rule, allowing all interfaces to change their configurations while
laying the infrastructure for future modes where an interface would be
blocked from making such a configuration.

====================
10GbE Intel Wired LAN Driver Updates 2016-04-25
This series contains updates to ixgbe and ixgbevf.
Emil provides several patches, starting with the consolidation of the
logic behind configuring spoof checking. Fixed an issue which was
causing link issues for backplane devices because x550em_a/x devices
did not have a default value for mac->ops.setup_link. Refactored the
ethtool stats to bring the logic closer to how ixgbe handles stats and
sets up per-queue stats for ixgbevf.
Mark adds a new register to wait for previous register writes to complete
before issuing a register read, which is needed when slower links are
in use. Fixed the flow control setup for x550em_a, the incorrect
fc_setup function was being used.
Don added a workaround for empty SFP+ cage crosstalk, since on some
systems the crosstalk could lead to link flap on empty SFP+ cages.
Jake converts ixgbe and ixgbevf to use the BIT() macro.
Alex Duyck adds support for partial GSO segmentation in the case of
tunnels for ixgbe and ixgbevf. Then preps for HyperV by moving the API
negotiation into mac_ops.
Arnd Bergmann provides a fix for the ARM compile warnings in linux-next

Merge branch 'nla_align-set-2'
Nicolas Dichtel says:
====================
netlink: align attributes when needed (patchset #2)
This is the continuation (series #2) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.
In patch #3, I didn't modify the function ila_encap_nlsize(). I was waiting
feedback for this patch: http://patchwork.ozlabs.org/patch/613766/
If it's approved, there will be an update to switch nla_total_size() to
nla_total_size_64bit() after the merge of net in net-next.

wcn36xx: Pad TIM PVM if needed
The wcn36xx FW expects a fixed size TIM PVM in the beacon template. If
supplied with a shorter than expected PVM it will overwrite the IE
following the TIM.
Squashed with fix from Jason Mobarak <jam(a)cozybit.com>:
Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh
beaconing. The field tim_off is always 0 for mesh mode, and thus
pvm_len (referring to the TIM length field) and pad are both incorrectly
calculated. Thus, msg_body.beacon_length is incorrectly calculated for
mesh mode. Fix this.

ca065d0cf80f ("udp: no longer use SLAB_DESTROY_BY_RCU")
3b24d854cb35 ("tcp/dccp: do not touch listener sk_refcnt under synflood")
These changes switched the datastructure used for TCP and UDP sockets
from hlist_nulls to hlist. This patch applies the necessary parts
of the net tree fix to net-next which were not automatic as part of the

ixgbe: use msleep for long delays
The newly added x550em_a support causes a link failure on ARM because of
an overly long time passed into udelay():
ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!
There are multiple variants of the ixgbe_acquire_swfw_sync_*() function,
and the other ones all use msleep(), so we can safely assume that all
callers are allowed to sleep, which makes msleep() a better replacement
than mdelay().

abstracted enough so that we can have a separate function between the two
so we can avoid changes in one breaking something in the other.

mangle the IP IDs on the inner header. This is needed because we will not
be modifying any fields from the start of the start of the outer transport
header to the start of the inner transport header as we are treating them
like they are just a block of IP options.

BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.
Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

ixgbe: Add work around for empty SFP+ cage crosstalk
It is possible on some systems that crosstalk could lead to link flap
on empty SFP+ cages. A new NVM bit was defined to let SW know it
needs to implement the work around which consists of verifying that
there is a module in the cage before acting on the LSC.

ixgbevf: refactor ethtool stats handling
This brings the logic closer to how we handle the stats in ixgbe and it
sets us up for introducing per-queue stats.
Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and
netdev stats respectively. This way we don't have to calculate the
stats based on register values which could lead to the counters not
being initialized properly when the interface is down.
IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues.
Also some defines were renamed to use the IXGBEVF prefix.

ixgbe: make 'action' field in struct ixgbe_fdir_filter a u64 value
This field is used to record the RX queue index for a redirect action
passed via ring_cookie field in struct ethtool_rx_flow_spec which is
a u64 value.
For ex: after adding a filter rule to redirect to a VF using ethtool
# echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
# ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000
querying for the rule shows the Action as 'Direct to queue 0'
# ethtool -n p4p1
4 RX rings available
Total 1 rules
Filter: 2045
Rule Type: Raw IPv4
Src IP addr: 192.168.0.1 mask: 0.0.0.0
Dest IP addr: 0.0.0.0 mask: 255.255.255.255
TOS: 0x0 mask: 0xff
Protocol: 0 mask: 0xff
L4 bytes: 0x0 mask: 0xffffffff
VLAN EtherType: 0x0 mask: 0xffff
VLAN: 0x0 mask: 0xffff
User-defined: 0x0 mask: 0xffffffffffffffff
Action: Direct to queue 0
With this fix, ethtool will report the right queue index even for VFs.
Action: Direct to queue 4294967296
Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more user friendly and matches with the 'action' value that
is passed when adding the rule.

X550EM_a/x did not have a default value for mac->ops.setup_link which
was causing link issues for backplane devices.
This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for
X550EM_a/x which is also default for X550. This will result in
mac->ops.setup_link calling the link setup function for the respective
PHY type in case we do not need a special function to deal with it.

ixgbe: set VLAN spoof checking unconditionally
Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.
This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.
Also default_vf_vlan_id and vlans_enabled were removed from the
vf_data_storage structure since they are not being used in the driver.

tcp-tso: do not split TSO packets at retransmit time
Linux TCP stack painfully segments all TSO/GSO packets before retransmits.
This was fine back in the days when TSO/GSO were emerging, with their
bugs, but we believe the dark age is over.
Keeping big packets in write queues, but also in stack traversal
has a lot of benefits.
- Less memory overhead, because write queues have less skbs
- Less cpu overhead at ACK processing.
- Better SACK processing, as lot of studies mentioned how
awful linux was at this ;)
- Less cpu overhead to send the rtx packets
(IP stack traversal, netfilter traversal, drivers...)
- Better latencies in presence of losses.
- Smaller spikes in fq like packet schedulers, as retransmits
are not constrained by TCP Small Queues.
1 % packet losses are common today, and at 100Gbit speeds, this
translates to ~80,000 losses per second.
Losses are often correlated, and we see many retransmit events
leading to 1-MSS train of packets, at the time hosts are already
under stress.

tcp: Carry txstamp_ack in tcp_fragment_tstamp
When a tcp skb is sliced into two smaller skbs (e.g. in
tcp_fragment() and tso_fragment()), it does not carry
the txstamp_ack bit to the newly created skb if it is needed.
The end result is a timestamping event (SCM_TSTAMP_ACK) will
be missing from the sk->sk_error_queue.
This patch carries this bit to the new skb2
in tcp_fragment_tstamp().

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree, mostly from Florian Westphal to sort out the lack of sufficient
validation in x_tables and connlabel preparation patches to add
nf_tables support. They are:
1) Ensure we don't go over the ruleset blob boundaries in
mark_source_chains().
2) Validate that target jumps land on an existing xt_entry. This extra
sanitization comes with a performance penalty when loading the ruleset.
3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables.
4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables.
5) Make sure the minimal possible target size in x_tables.
6) Similar to #3, add xt_compat_check_entry_offsets() for compat code.
7) Check that standard target size is valid.
8) More sanitization to ensure that the target_offset field is correct.
9) Add xt_check_entry_match() to validate that matches are well-formed.
10-12) Three patch to reduce the number of parameters in
translate_compat_table() for {arp,ip,ip6}tables by using a container
structure.
13) No need to return value from xt_compat_match_from_user(), so make
it void.
14) Consolidate translate_table() so it can be used by compat code too.
15) Remove obsolete check for compat code, so we keep consistent with
what was already removed in the native layout code (back in 2007).
16) Get rid of target jump validation from mark_source_chains(),
obsoleted by #2.
17) Introduce xt_copy_counters_from_user() to consolidate counter
copying, and use it from {arp,ip,ip6}tables.
18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump
functions.
19) Move nf_connlabel_match() to xt_connlabel.
20) Skip event notification if connlabel did not change.
21) Update of nf_connlabels_get() to make the upcoming nft connlabel
support easier.
23) Remove spinlock to read protocol state field in conntrack.

vxlan: break dependency with netdev drivers
Currently all drivers depend and autoload the vxlan module because how
vxlan_get_rx_port is linked into them. Remove this dependency:
By using a new event type in the netdevice notifier call chain we proxy
the request from the drivers to flush and resetup the vxlan ports not
directly via function call but by the already existing netdevice
notifier call chain.
I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so.
We don't need to save those ids, as the event type field is an unsigned
long and using specialized event types for this purpose seemed to be a
more elegant way. This also comes in beneficial if in future we want to
add offloading knobs for vxlan.

====================
Mellanox 100G mlx5 driver receive path optimizations
Changes from V2:
- Rebased to 46e7b8d8d53b ("net: dsa: kill circular reference with slave priv")
- Updated: ("net/mlx5e: Support RX multi-packet WQE (Striding RQ)")
* Per Eric Dumazet comment we changed the driver memory handling scheme to
work with order-0 pages rather than order-5 via split_page().
* This means that now a mlx5e rx skb can hold one or (more in case of HW LRO)
skb frag each pointing to a 4K order-0 page rather than one frag with order-5 page.
- Updated: ("net/mlx5e: Add fragmented memory support for RX multi packet WQE")
* Code refactoring and code reuse due the split_page() mechanism,
now the MPWQE and fragmented MPWQE handling almost look the same,
and share most of the code.
- In some cases we see 2%-3% packet rate degradation in comparison to the order-5 pages approach,
due to split_page() cpu consumption, but still we do see 3%-10% improvement in comparison to the
current linear SKB approach.
- We do believe that now the driver memory scheme is significantly less vulnerable
to the memory DOS attack Eric pointed at.

This series includes Some RX modifications and optimizations for
the mlx5 Ethernet driver.
From Rana, we have one patch that adds the support for Connectx-4
queue counters.
From Tariq, several patches that are centralized around improving
RX path message rate, CPU and Memory utilization, in each patch
commit message you will find the performance improvements numbers
related to that specific patch.
In the 2nd patch we used a queue counter to report "out of buffer"
dropped packet count, "Dropped packets due to lack of software resources"
3rd patch modifies the driver's to RSS default value to be spread along the
close NUMA node cores only for better out of the box experience.
In the 4th and 5th patches we utilized the use of RX multi-packet WQE
(Striding RQ) for better memory utilization especially in case of hardware
LRO is enabled and for better message rate for small packets.
In the 6th and 7th patches we added a fallback mechanism to use fragmented
memory when allocating large WQE strides fails, using UMR
(User Memory Registration) and ICO (Internal Control Operations) SQs.
In the 8th to 11th patches we did some small modification which show some small
extra improvements.

net/mlx5e: Support RX multi-packet WQE (Striding RQ)
Introduce the feature of multi-packet WQE (RX Work Queue Element)
referred to as (MPWQE or Striding RQ), in which WQEs are larger
and serve multiple packets each.
Every WQE consists of many strides of the same size, every received
packet is aligned to a beginning of a stride and is written to
consecutive strides within a WQE.
In the regular approach, each regular WQE is big enough to be capable
of serving one received packet of any size up to MTU or 64K in case of
device LRO is enabled, making it very wasteful when dealing with
small packets or device LRO is enabled.
For its flexibility, MPWQE allows a better memory utilization
(implying improvements in CPU utilization and packet rate) as packets
consume strides according to their size, preserving the rest of
the WQE to be available for other packets.
MPWQE default configuration:
Num of WQEs = 16
Strides Per WQE = 2048
Stride Size = 64 byte
The default WQEs memory footprint went from 1024*mtu (~1.5MB) to
16 * 2048 * 64 = 2MB per ring.
However, HW LRO can now be supported at no additional cost in memory
footprint, and hence we turn it on by default and get an even better
performance.
Performance tested on ConnectX4-Lx 50G.
To isolate the feature under test, the numbers below were measured with
HW LRO turned off. We verified that the performance just improves when
LRO is turned back on.
* Netperf single TCP stream:
- BW raised by 10-15% for representative packet sizes:
default, 64B, 1024B, 1478B, 65536B.
* Netperf multi TCP stream:
- No degradation, line rate reached.
* Pktgen: packet rate raised by 2-10% for traffic of different message
sizes: 64B, 128B, 256B, 1024B, and 1500B.
* Pktgen: packet loss in bursts of small messages (64byte),
single stream:
- | num packets | packets loss before | packets loss after
| 2K | ~ 1K | 0
| 8K | ~ 6K | 0
| 16K | ~13K | 0
| 32K | ~28K | 0
| 64K | ~57K | ~24K
As expected as the driver can receive as many small packets (<=64B) as
the number of total strides in the ring (default = 2048 * 16) vs. 1024
(default ring size regardless of packets size) before this feature.

net/mlx5: Introduce device queue counters
A queue counter can collect several statistics for one or more
hardware queues (QPs, RQs, etc ..) that the counter is attached to.
For Ethernet it will provide an "out of buffer" counter which
collects the number of all packets that are dropped due to lack
of software buffers.
Here we add device commands to alloc/query/dealloc queue counters.

Jeff Kirsher says:
====================
100GbE Intel Wired LAN Driver Updates 2016-04-20
This series contains updates to fm10k only.
Jacob provides majority of the changes in this series, starting with the
addition of helper functions to reduce code duplication and the amount
of code indentation. Fixed the use or should we say abuse of the ethtool
stats API, which could result in corrupt memory or misleading statistic
output. Added the appropriate rtnl_lock() and rtnl_unlock() to avoid
RCU warnings during AER events. Come to find out, the PTP/1588 support
is not working with the current version of switch management software
and possibly never worked, so just remove support for PTP/1588 for now.
Fixed how error responses from the switch manager after a LPORT_MAP
request are handled, originally which were silently being ignored.
Fixed up code documentation to hopefully ease the code and comment
comprehension. Fixed a possible NULL pointer dereference after a
kcalloc(), where when writing a new default redirection table, and we
needed to populate a new RSS table using ethtool_rxfh_indir_default().
We populate this table into a region of memory allocated using kcalloc()
but never check it for NULL.
Alex adds support for bulk transmit cleanup for fm10k, like he did for
all of our other drivers.
Ngai-Mint fixes a number of issues with the unicast and multicast address
syncs. Where an issue would occur when the netdev is pre-configured to
either multicast mode and is enabled for the first time.

above can make it somewhat easy to understand which bit you're looking
at, it makes the break points not line up. Re-draw the numbers using
base 8, and mark the bit values every 8 bits at the top. This should
make it more easy to grasp the table quickly.

fm10k: fix documentation of fm10k_tlv_parse_attr
fm10k_tlv_parse_attr is supposed to return FM10K_NOT_IMPLEMENTED for any
TLV who's attribute id lies outside the range of results. It does not do
this today. In addition, the documentation does not indicate that other
attributes which are not implemented for a given TLV will be silently
ignored. Fix this. Clean up the logic so that we don't rely on the fact
that FM10K_NOT_IMPLEMENTED is greater than zero, as this can easily
cause confusion.
A future extension could look into some way of reporting unknown TLVs
in order to make issues more easily discoverable. We can't just return
FM10K_NOT_IMPLEMENTED here because we don't want to drop the entire
message if it has an unknown TLV.
While here, update the copyright year.

fm10k: do not disable PCI device in fm10k_io_error_detected
fm10k_io_error_detected() does not need to call pci_disable_device(). In
the cases where the reset needs to occur, the stack flow will result in
calling fm10k_remove() which already disables the PCI device. If we
leave the pci_disable_device(), we result in a warning about disabling
an already disabled device.
Many PCI drivers do call pci_disable_device() in their .error_detected()
routines, but it does not appear to be required. In addition, these
drivers have a check "is_pci_enabled()" call in their remove routines,
which is how they chose to handle the duplicate device disable.
This seems incorrect, since the PCI device structure is reference
counted. It is very possible that the reference count for the PCI device
could be greater than 1. In this case, you would remove the PCI device
within the error_detected routine, reducing count to 1, then remove it
again in the remove function, reducing it to zero. This would result in
yet another disable somewhere else failing. Thus, we shouldn't be using
is_pci_enabled() to check for this issue. Instead, just remove the
extraneous pci_device_disable() found within the error_detected routine.

fm10k: correctly handle LPORT_MAP error
Currently, any error responses from the switch manager after an
LPORT_MAP request are silently ignored. At most the mailbox message will
be reported as an error. This can result in unexpected behavior when the
switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.
If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.
The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

fm10k: Fix multicast mode sync issues
Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.
Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

fm10k: prevent RCU issues during AER events

need rtnl_lock() around fm10k_open during fm10k_io_resume. Follow the

rtnetlink: add new RTM_GETSTATS message to dump link stats
This patch adds a new RTM_GETSTATS message to query link stats via netlink
from the kernel. RTM_NEWLINK also dumps stats today, but RTM_NEWLINK
returns a lot more than just stats and is expensive in some cases when
frequent polling for stats from userspace is a common operation.
RTM_GETSTATS is an attempt to provide a light weight netlink message
to explicity query only link stats from the kernel on an interface.
The idea is to also keep it extensible so that new kinds of stats can be
added to it in the future.
This patch adds the following attribute for NETDEV stats:
struct nla_policy ifla_stats_policy[IFLA_STATS_MAX + 1] = {
[IFLA_STATS_LINK_64] = { .len = sizeof(struct rtnl_link_stats64) },
};
Like any other rtnetlink message, RTM_GETSTATS can be used to get stats of
a single interface or all interfaces with NLM_F_DUMP.
Future possible new types of stat attributes:
link af stats:
- IFLA_STATS_LINK_IPV6 (nested. for ipv6 stats)
- IFLA_STATS_LINK_MPLS (nested. for mpls/mdev stats)
extended stats:
- IFLA_STATS_LINK_EXTENDED (nested. extended software netdev stats like bridge,
vlan, vxlan etc)
- IFLA_STATS_LINK_HW_EXTENDED (nested. extended hardware stats which are
available via ethtool today)
This patch also declares a filter mask for all stat attributes.
User has to provide a mask of stats attributes to query. filter mask
can be specified in the new hdr 'struct if_stats_msg' for stats messages.
Other important field in the header is the ifindex.
This api can also include attributes for global stats (eg tcp) in the future.
When global stats are included in a stats msg, the ifindex in the header
must be zero. A single stats message cannot contain both global and
netdev specific stats. To easily distinguish them, netdev specific stat
attributes name are prefixed with IFLA_STATS_LINK_
Without any attributes in the filter_mask, no stats will be returned.
This patch has been tested with mofified iproute2 ifstat.

at86rf230: increase sleep to off timings
I expierenced when setting channel while sleep mode it didn't changed
the channel inside the hardware registers. Then I got another report of
an user which has similar issues.
I increased the sleep to off state change timing, which is according
at86rf233 at maximum 1000 us. After this change I got no similar effects
again.
I tried another option to wait on AWAKE_END irq, which can be used to
wait until the transceiver is awaked. I tested it and the IRQ took 4
seconds after starting state change. I don't believe it takes 4 seconds
to go into the TRX_OFF state from SLEEP state. The alternative is to
increase the timings which seems to work.

bpf: add event output helper for notifications/sampling/logging
This patch adds a new helper for cls/act programs that can push events
to user space applications. For networking, this can be f.e. for sampling,
debugging, logging purposes or pushing of arbitrary wake-up events. The
idea is similar to a43eec304259 ("bpf: introduce bpf_perf_event_output()
helper") and 39111695b1b8 ("samples: bpf: add bpf_perf_event_output example").
The eBPF program utilizes a perf event array map that user space populates
with fds from perf_event_open(), the eBPF program calls into the helper
f.e. as skb_event_output(skb, &my_map, BPF_F_CURRENT_CPU, raw, sizeof(raw))
so that the raw data is pushed into the fd f.e. at the map index of the
current CPU.
User space can poll/mmap/etc on this and has a data channel for receiving
events that can be post-processed. The nice thing is that since the eBPF
program and user space application making use of it are tightly coupled,
they can define their own arbitrary raw data format and what/when they
want to push.
While f.e. packet headers could be one part of the meta data that is being
pushed, this is not a substitute for things like packet sockets as whole
packet is not being pushed and push is only done in a single direction.
Intention is more of a generically usable, efficient event pipe to applications.
Workflow is that tc can pin the map and applications can attach themselves
e.g. after cls/act setup to one or multiple map slots, demuxing is done by
the eBPF program.
Adding this facility is with minimal effort, it reuses the helper
introduced in a43eec304259 ("bpf: introduce bpf_perf_event_output() helper")
and we get its functionality for free by overloading its BPF_FUNC_ identifier
for cls/act programs, ctx is currently unused, but will be made use of in
future. Example will be added to iproute2's BPF example files.

Add a BPF_F_CURRENT_CPU flag to optimize the use-case where user space has
per-CPU ring buffers and the eBPF program pushes the data into the current
CPU's ring buffer which saves us an extra helper function call in eBPF.
Also, make sure to properly reserve the remaining flags which are not used.

arcnet: com90xx: add __init attribute
Add __init attribute on a function that is only called from other __init
functions and that is not inlined, at least with gcc version 4.8.4 on an
x86 machine with allyesconfig. Currently, the function is put in the
.text.unlikely segment. Declaring it as __init will cause it to be put in
the .init.text and to disappear after initialization.
The result of objdump -x on the function before the change is as follows:
0000000000000000 l F .text.unlikely 00000000000000bf check_mirror
And after the change it is as follows:
0000000000000000 l F .init.text 00000000000000ba check_mirror
Done with the help of Coccinelle. The semantic patch checks for local
static non-init functions that are called from an __init function and are
not called from any other function.

Struct ctl_table_header holds pointer to sysctl table which could be used
for freeing it after unregistration. IPv4 sysctls already use that.
Remove redundant NULL assignment: ndev allocated using kzalloc.
This also saves some bytes: sysctl table could be shorter than
DEVCONF_MAX+1 if some options are disable in config.

net: Align IFLA_STATS64 attributes properly on architectures that need it.
Since the nlattr header is 4 bytes in size, it can cause the netlink
attribute payload to not be 8-byte aligned.
This is particularly troublesome for IFLA_STATS64 which contains 64-bit
statistic values.
Solve this by creating a dummy IFLA_PAD attribute which has a payload
which is zero bytes in size. When HAVE_EFFICIENT_UNALIGNED_ACCESS is
false, we insert an IFLA_PAD attribute into the netlink response when
necessary such that the IFLA_STATS64 payload will be properly aligned.
With help and suggestions from Eric Dumazet.

ath9k: interpret requested txpower in EIRP domain
Tx power limitations at upper layers are interpreted in
the EIRP domain. When the user requests a given maximum
txpower, e.g. with: 'iw phy0 set txpower fixed 1500',
he expects the EIRP to be at or below 15dBm.
In ath9k_hw_apply_txpower(), the interpretation is
different: the antenna-gain is capped against the
current txpower limit in the regulatory, but not
against the user set value. It ensures that the
resulting EIRP is below the limit defined by the
active countrycode, but not below the value the
user requested.
In a scenario like e.g.
a) antenna_gain=6
b) countrycode limits to eirp=18
c) user set txpower=15
this will cause a setting for AR_PHY_POWER_TX_RATE
regs resulting in an EIRP > 15.
This patch ensures that antenna-gain is considered
whenever the txpower limit is adjusted and with that
the user set limits are kept.

ath10k: add dynamic tx mode switch config support for qca4019
push-pull mode needs certain amount the host driver involvement for
managing queues in the host memory and packet delivery to firmware.
qca4019 wifi firmware has an option to stay in push mode for less
number of active traffic flow and then switch to push-pull mode when
the active traffic flow goes beyond the certain limit.
The advantage of staying in push mode for less active traffic is, the
host cpu consumption is reduced. qca4019 firmware supports this
flexibility of the mode switch. It takes the host driver interest
(LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID,
LOW_PERF - fw would stay in push mode and switch to push-pull
based on demand.
HIGH_PERF - fw would stay in push-pull mode from the boot.
To make this configuration generic, new WMI services
WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL,
WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode
switch support availability in firmware.
Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is
configured to the firmware.

Upon firmware assert, restart work will be triggered so that mac80211

work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info
for operating channel. During reconfigure, since mac80211 already has
valid channel context for given radio, channel context iteration return
num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning
channel context to rx_channel when driver restart is in progress.

hv_netvsc: Implement support for VF drivers on Hyper-V
Support VF drivers on Hyper-V. On Hyper-V, each VF instance presented to
the guest has an associated synthetic interface that shares the MAC address
with the VF instance. Typically these are bonded together to support
live migration. By default, the host delivers all the incoming packets
on the synthetic interface. Once the VF is up, we need to explicitly switch
the data path on the host to divert traffic onto the VF interface. Even after
switching the data path, broadcast and multicast packets are always delivered
on the synthetic interface and these will have to be injected back onto the
VF interface (if VF is up).
This patch implements the necessary support in netvsc to support Linux
VF drivers.

This patchset factorizes the mv88e6xxx code by sharing a new extendable
info structure to store static data such as switch family, product
number, number of ports, number of databases and the name.
The next step is to add a "flags" bitmap member to the info structure in
order to simplify the shared code with a feature-based logic instead of
checking their family/ID.
This is a step forward having a single mv88e6xxx driver supporting many
similar devices, like any usual Linux driver.

nfp: cleanups and improvements
Main purpose of this set is to get rid of doing potentially long
mdelay()s but it also contains some trivial changes I've accumulated.
First two patches fix harmless copy-paste errors, next two clean up
the documentation and remove unused defines. Patch 5 clarifies the
interpretation of RX descriptor fields. Patch 6, by far the biggest,
adds ability to perform FW reconfig asynchronously thanks to which
we can stop using mdelay().

nfp: add async reconfiguration mechanism
Some callers of nfp_net_reconfig() are in atomic context so
we used to busy wait for commands to complete. In worst case
scenario that means locking up a core for up to 5 seconds
when a command times out. Lets add a timer-based mechanism
of asynchronously checking whether reconfiguration completed
successfully for atomic callers to use. Non-atomic callers
can now just sleep.
The approach taken is quite simple because (1) synchronous
reconfigurations always happen under RTNL (or before device
is registered); (2) we can coalesce pending reconfigs.
There is no need for request queues, timer which eventually
takes a look at reconfiguration result to report errors is
good enough.

Remove this extra call to socfpga_dwmac_setup.
Also we should not be calling socfpga_dwmac_setup() directly without wrapping
it around the proper reset assert/deasserts. That is because the
socfpga_dwmac_setup() is setting up PHY modes in the system manager, and it
is requires the EMAC's to be in reset during the PHY setup.

Add support for offloads with IPv6 GRE tunnels
This patch series enables the use of segmentation and checksum offloads
with IPv6 based GRE tunnels.
In order to enable this series I had to make a change to
iptunnel_handle_offloads so that it would no longer free the skb. This was
necessary as there were multiple paths in the IPv6 GRE code that required
the skb to still be present so it could be freed. As it turned out I
believe this actually fixes a bug that was present in FOU/GUE based tunnels
anyway.

ip_tunnel_core: iptunnel_handle_offloads returns int and doesn't free skb
This patch updates the IP tunnel core function iptunnel_handle_offloads so
that we return an int and do not free the skb inside the function. This
actually allows us to clean up several paths in several tunnels so that we
can free the skb at one point in the path without having to have a
secondary path if we are supporting tunnel offloads.
In addition it should resolve some double-free issues I have found in the
tunnels paths as I believe it is possible for us to end up triggering such
an event in the case of fou or gue.

====================
net: w5100: add support W5100/W5200 for SPI interface
This series add support for Wiznet W5100 and W5200 for SPI interface.
We can easily find the ethernet modules and shield for Arduino with
these chips for purchase. I've tested them with BeagleBone.
Wiznet W5100 for mmio access has already supported by w5100 driver.
In order to share the code between mmio mode and SPI mode, this series
firstly adds ability to support another register access interface to
the existing w5100 driver. This ground work also requires to introduce
workqueue and threaded irq because SPI transfers are callable only from
contexts that can sleep unlike mmio access.
The latter part of this series adds w5100-spi driver which actually
support W5100 and W5200 for SPI interface. Supporting W5100 is
straight forward because it only required to add a register access
interface by the SPI transfer. W5100 and W5200 have similar memory
map which justifies adding W5200 support to w5100 driver.
* Changes from v2 to v3
- Add comment for reg_lock
- Add ability to allocate ops specific data structure
- Allocate w5200 ops specific data structure to put DMA-safe buffer
- Add missing chip_id assignment for w5100_*_ops
* Changes from v1 to v2
- Use a plain single pointer instead of SKB queue, spotted by David S. Miller
- Correct timeout period in w5100_command
- Use spi_write_then_read instead of spi_write which needs DMA-safe buffer

net: w5100: support W5200
This adds support for W5200 chip.
W5100 and W5200 have similar memory map although some of their offsets
are different. The register access sequences between them are different
but w5100 driver has abstraction layer for difference bus interface
modes so it is easy to add W5200 support to w5100 and w5100-spi drivers.

net: w5100: enable to support sleepable register access interface
SPI transfer routines are callable only from contexts that can sleep.
This adds ability to tell the core driver that the interface mode
cannot access w5100 register on atomic contexts. In this case,
workqueue and threaded irq are required.
This also corrects timeout period waiting for command register to be
automatically cleared because the latency of the register access with
SPI transfer can be interfered by other contexts.

net: w5100: add ability to support other bus interface
The w5100 driver currently only supports direct and indirect bus
interface mode which use MMIO space for accessing w5100 registers.
In order to support SPI interface mode which is supported by W5100 chip,
this makes the bus interface abstraction layer more generic so that
separated w5100-spi driver can use w5100 driver as core module.

vxlan: synchronously and race-free destruction of vxlan sockets
Due to the fact that the udp socket is destructed asynchronously in a
work queue, we have some nondeterministic behavior during shutdown of
vxlan tunnels and creating new ones. Fix this by keeping the destruction
process synchronous in regards to the user space process so IFF_UP can
be reliably set.
udp_tunnel_sock_release destroys vs->sock->sk if reference counter
indicates so. We expect to have the same lifetime of vxlan_sock and
vxlan_sock->sock->sk even in fast paths with only rcu locks held. So
only destruct the whole socket after we can be sure it cannot be found
by searching vxlan_net->sock_list.

2.set the autoneg to AUTONEG_DISABLE, it calls the

The BMCR_LOOPBACK bit should be preserved.

For a listening sctp endpoint, we will just dump it's ep info.
For a sctp connection, we will the assoc info and it's ep info.
The ss dump will looks like:

The entries with '- ESTAB' are the assocs, some of them may belong to
the same endpoint. So we will dump the parent endpoint first, like the
entry with 'LISTEN'. then dump the assocs. ep and assocs entries will
be dumped in right order so that ss can show them in tree format easily.
Besides, this patchset also simplifies sctp proc codes, cause it has
some similar codes with sctp diag in sctp transport traversal.
v1->v2:
1. inet_diag_get_handler needs to return it as const.
2. merge 5/7 into 2/7 of v1.
v2->v3:
do some improvements and fixes in patch 1-4, see the details in
each patch's comment.

sctp: fix some rhashtable functions using in sctp proc/diag
When rhashtable_walk_init return err, no release function should be
called, and when rhashtable_walk_start return err, we should only invoke
rhashtable_walk_exit to release the source.
But now when sctp_transport_walk_start return err, we just call
rhashtable_walk_stop/exit, and never care about if rhashtable_walk_init
or start return err, which is so bad.
We will fix it by calling rhashtable_walk_exit if rhashtable_walk_start
return err in sctp_transport_walk_start, and if sctp_transport_walk_start
return err, we do not need to call sctp_transport_walk_stop any more.
For sctp proc, we will use 'iter->start_fail' to decide if we will call
rhashtable_walk_stop/exit.

- change inet_diag_msg_paddrs_fill() name to inet_diag_msg_sctpaddrs_fill.
- add inet_diag_msg_sctpinfo_fill() to make asoc/ep fill code clearer.
- add inet_diag_msg_sctpasoc_fill() to make asoc fill code clearer.
- merge inet_asoc_diag_fill() and inet_ep_diag_fill() to

- call sctp_diag_get_info() directly, instead by handler, cause the caller
is in the same file with it.
- call lock_sock in sctp_tsp_dump_one() to make sure we call get sctp info
safely.
- after lock_sock(sk), we should check sk != assoc->base.sk.
- change mem[SK_MEMINFO_WMEM_ALLOC] to asoc->sndbuf_used for asoc dump when
asoc->ep->sndbuf_policy is set. don't use INET_DIAG_MEMINFO attr any more.

sctp: simplify sk_receive_queue locking
SCTP already serializes access to rcvbuf through its sock lock:
sctp_recvmsg takes it right in the start and release at the end, while
rx path will also take the lock before doing any socket processing. On
sctp_rcv() it will check if there is an user using the socket and, if
there is, it will queue incoming packets to the backlog. The backlog
processing will do the same. Even timers will do such check and
re-schedule if an user is using the socket.
Simplifying this will allow us to remove sctp_skb_list_tail and get ride
of some expensive lockings. The lists that it is used on are also
mangled with functions like __skb_queue_tail and __skb_unlink in the
same context, like on sctp_ulpq_tail_event() and sctp_clear_pd().
sctp_close() will also purge those while using only the sock lock.
Therefore the lockings performed by sctp_skb_list_tail() are not
necessary. This patch removes this function and replaces its calls with
just skb_queue_splice_tail_init() instead.
The biggest gain is at sctp_ulpq_tail_event(), because the events always
contain a list, even if it's queueing a single skb and this was
triggering expensive calls to spin_lock_irqsave/_irqrestore for every
data chunk received.
As SCTP will deliver each data chunk on a corresponding recvmsg, the
more effective the change will be.

tcp: do not mess with listener sk_wmem_alloc
When removing sk_refcnt manipulation on synflood, I missed that
using skb_set_owner_w() was racy, if sk->sk_wmem_alloc had already
transitioned to 0.
We should hold sk_refcnt instead, but this is a big deal under attack.
(Doing so increase performance from 3.2 Mpps to 3.8 Mpps only)
In this patch, I chose to not attach a socket to syncookies skb.
Performance is now 5 Mpps instead of 3.2 Mpps.

tipc: let first message on link be a state message
According to the link FSM, a received traffic packet can take a link
from state ESTABLISHING to ESTABLISHED, but the link can still not be
fully set up in one atomic operation. This means that even if the the
very first packet on the link is a traffic packet with sequence number
1 (one), it has to be dropped and retransmitted.
This can be avoided if we let the mentioned packet be preceded by a
LINK_PROTOCOL/STATE message, which takes up the endpoint before the
arrival of the traffic.
We add this small feature in this commit.
This is a fully compatible change.

tipc: ensure that first packets on link are sent in order
In some link establishment scenarios we see that packet #2 may be sent
out before packet #1, forcing the receiver to demand retransmission of
the missing packet. This is harmless, but may cause confusion among
people tracing the packet flow.
Since this is extremely easy to fix, we do so by adding en extra send
call to the bearer immediately after the link has come up.

tipc: reduce transmission rate of reset messages when link is down
When a link is down, it will continuously try to re-establish contact
with the peer by sending out a RESET or an ACTIVATE message at each
timeout interval. The default value for this interval is currently
375 ms. This is wasteful, and may become a problem in very large
clusters with dozens or hundreds of nodes being down simultaneously.
We now introduce a simple backoff algorithm for these cases. The
first five messages are sent at default rate; thereafter a message
is sent only each 16th timer interval.
This will cover the vast majority of link recycling cases, since the
endpoint starting last will transmit at the higher speed, and the link
should normally be established well be before the rate needs to be
reduced.
The only case where we will see a degradation of link re-establishment
times is when the endpoints remain intact, and a glitch in the
transmission media is causing the link reset. We will then experience
a worst-case re-establishing time of 6 seconds, something we deem
acceptable.

tipc: guarantee peer bearer id exchange after reboot
When a link endpoint is going down locally, e.g., because its interface
is being stopped, it will spontaneously send out a RESET message to
its peer, informing it about this fact. This saves the peer from
detecting the failure via probing, and hence gives both speedier and
less resource consuming failure detection on the peer side.
According to the link FSM, a receiver of a RESET message, ignoring the
reason for it, must now consider the sender ready to come back up, and
starts periodically sending out ACTIVATE messages to the peer in order
to re-establish the link. Also, according to the FSM, the receiver of
an ACTIVATE message can now go directly to state ESTABLISHED and start
sending regular traffic packets. This is a well-proven and robust FSM.
However, in the case of a reboot, there is a small possibilty that link
endpoint on the rebooted node may have been re-created with a new bearer
identity between the moment it sent its (pre-boot) RESET and the moment
it receives the ACTIVATE from the peer. The new bearer identity cannot
be known by the peer according to this scenario, since traffic headers
don't convey such information. This is a problem, because both endpoints
need to know the correct value of the peer's bearer id at any moment in
time in order to be able to produce correct link events for their users.
The only way to guarantee this is to enforce a full setup message
exchange (RESET + ACTIVATE) even after the reboot, since those messages
carry the bearer idientity in their header.
In this commit we do this by introducing and setting a "stopping" bit in
the header of the spontaneously generated RESET messages, informing the
peer that the sender will not be immediately ready to re-establish the
link. A receiver seeing this bit must act as if this were a locally
detected connectivity failure, and hence has to go through a full two-
way setup message exchange before any link can be re-established.
Although never reported, this problem seems to have always been around.
This protocol addition is fully backwards compatible.

mwifiex: factor out mwifiex_cancel_pending_scan_cmd
Releasing the scan_pending lock in mwifiex_check_next_scan_command
introduces a short window where pending scan commands can be removed
or added before removing them all in mwifiex_cancel_pending_scan_cmd.
I think this is safe, since the worst thing to happen is that a
pending scan cmd is removed by the command handler. Adding new scan
commands is not possible while one is pending, see scan_processing flag.
Since all commands are removed from the queue anyway, we don't care if
some commands are removed by a different code path earlier, the final
state remains the same.
I assume, that the critical section needed for the check has been
extended over clearing the pending scan queue out of convenience. The
lock was already held and releasing it and grab it again was just
more work. It doesn't seem to be necessary because of concurrency.

This patch converts all helpers that can use ARG_PTR_TO_RAW_STACK as argument

bpf_skb_get_tunnel_opt(). For tracing, this optimizes bpf_get_current_comm()
and bpf_probe_read(). The check in bpf_skb_load_bytes() for MAX_BPF_STACK can
also be removed since the verifier already makes sure we stay within bounds
on stack buffers.

bpf, verifier: add ARG_PTR_TO_RAW_STACK type
When passing buffers from eBPF stack space into a helper function, we have
ARG_PTR_TO_STACK argument type for helpers available. The verifier makes sure
that such buffers are initialized, within boundaries, etc.
However, the downside with this is that we have a couple of helper functions
such as bpf_skb_load_bytes() that fill out the passed buffer in the expected
success case anyway, so zero initializing them prior to the helper call is
unneeded/wasted instructions in the eBPF program that can be avoided.
Therefore, add a new helper function argument type called ARG_PTR_TO_RAW_STACK.
The idea is to skip the STACK_MISC check in check_stack_boundary() and color
the related stack slots as STACK_MISC after we checked all call arguments.
Helper functions using ARG_PTR_TO_RAW_STACK must make sure that every path of
the helper function will fill the provided buffer area, so that we cannot leak
any uninitialized stack memory. This f.e. means that error paths need to
memset() the buffers, but the expected fast-path doesn't have to do this
anymore.
Since there's no such helper needing more than at most one ARG_PTR_TO_RAW_STACK
argument, we can keep it simple and don't need to check for multiple areas.
Should in future such a use-case really appear, we have check_raw_mode() that
will make sure we implement support for it first.

bpf, verifier: add bpf_call_arg_meta for passing meta data
Currently, when the verifier checks calls in check_call() function, we
call check_func_arg() for all 5 arguments e.g. to make sure expected types
are correct. In some cases, we collect meta data (here: map pointer) to
perform additional checks such as checking stack boundary on key/value
sizes for subsequent arguments. As we're going to extend the meta data,
add a generic struct bpf_call_arg_meta that we can use for passing into
check_func_arg().

sctp: add support for RPS and RFS
This patch adds what's missing to properly support RPS and RFS on SCTP,
as some of it is already implemented in common calls.
Having support for RPS and RFS allows better scaling specially because
not all NICs support hashing SCTP headers.
Save the hash right when we dequeue a skb from inqueue so we do it only

tipc: fix a race condition leading to subscriber refcnt bug
Until now, the requests sent to topology server are queued
to a workqueue by the generic server framework.
These messages are processed by worker threads and trigger the
registered callbacks.
To reduce latency on uniprocessor systems, explicit rescheduling
is performed using cond_resched() after MAX_RECV_MSG_COUNT(25)
messages.
This implementation on SMP systems leads to an subscriber refcnt
error as described below:
When a worker thread yields by calling cond_resched() in a SMP
system, a new worker is created on another CPU to process the
pending workitem. Sometimes the sleeping thread wakes up before
the new thread finishes execution.
This breaks the assumption on ordering and being single threaded.
The fault is more frequent when MAX_RECV_MSG_COUNT is lowered.
If the first thread was processing subscription create and the
second thread processing close(), the close request will free
the subscriber and the create request oops as follows:

- rename tipc_conn_shutdown() to tipc_conn_release().
- move connection release callback execution from tipc_close_conn()
to a new function tipc_sock_release(), which is executed before

Thus we release the subscriber during connection release procedure

Alexander Duyck says:
====================
GRO Fixed IPv4 ID support and GSO partial support
This patch series sets up a few different things.
First it adds support for GRO of frames with a fixed IP ID value. This
will allow us to perform GRO for frames that go through things like an IPv6
to IPv4 header translation.
The second item we add is support for segmenting frames that are generated
this way. Most devices only support an incrementing IP ID value, and in
the case of TCP the IP ID can be ignored in many cases since the DF bit
should be set. So we can technically segment these frames using existing
TSO if we are willing to allow the IP ID to be mangled. As such I have
added a matching feature for the new form of GRO/GSO called TCP IPv4 ID
mangling. With this enabled we can assemble and disassemble a frame with
the sequence number fixed and the only ill effect will be that the IPv4 ID
will be altered which may or may not have any noticeable effect. As such I
have defaulted the feature to disabled.
The third item this patch series adds is support for partial GSO
segmentation. Partial GSO segmentation allows us to split a large frame
into two pieces. The first piece will have an even multiple of MSS worth
of data and the headers before the one pointed to by csum_start will have
been updated so that they are correct for if the data payload had already
been segmented. By doing this we can do things such as precompute the
outer header checksums for a frame to be segmented allowing us to perform
TSO on devices that don't support tunneling, or tunneling with outer header
checksums.
This patch set is based on the net-next tree, but I included "net: remove
netdevice gso_min_segs" in my tree as I assume it is likely to be applied
before this patch set will and I wanted to avoid a merge conflict.
v2: Fixed items reported by Jesse Gross
fixed missing GSO flag in MPLS check
adding DF check for MANGLEID
Moved extra GSO feature checks into gso_features_check
Rebased batches to account for "net: remove netdevice gso_min_segs"
Driver patches from the first patch set should still be compatible. However
I do have a few changes in them so I will submit a v2 of those to Jeff
Kirsher once these patches are accepted into net-next.

GSO: Support partial segmentation offload
This patch adds support for something I am referring to as GSO partial.
The basic idea is that we can support a broader range of devices for
segmentation if we use fixed outer headers and have the hardware only
really deal with segmenting the inner header. The idea behind the naming
is due to the fact that everything before csum_start will be fixed headers,
and everything after will be the region that is handled by hardware.
With the current implementation it allows us to add support for the
following GSO types with an inner TSO_MANGLEID or TSO6 offload:
NETIF_F_GSO_GRE
NETIF_F_GSO_GRE_CSUM
NETIF_F_GSO_IPIP
NETIF_F_GSO_SIT
NETIF_F_UDP_TUNNEL
NETIF_F_UDP_TUNNEL_CSUM
In the case of hardware that already supports tunneling we may be able to
extend this further to support TSO_TCPV4 without TSO_MANGLEID if the
hardware can support updating inner IPv4 headers.

GRO: Add support for TCP with fixed IPv4 ID field, limit tunnel IP ID values
This patch does two things.
First it allows TCP to aggregate TCP frames with a fixed IPv4 ID field. As
a result we should now be able to aggregate flows that were converted from
IPv6 to IPv4. In addition this allows us more flexibility for future
implementations of segmentation as we may be able to use a fixed IP ID when
segmenting the flow.
The second thing this does is that it places limitations on the outer IPv4
ID header in the case of tunneled frames. Specifically it forces the IP ID
to be incrementing by 1 unless the DF bit is set in the outer IPv4 header.
This way we can avoid creating overlapping series of IP IDs that could
possibly be fragmented if the frame goes through GRO and is then
resegmented via GSO.

GSO: Add GSO type for fixed IPv4 ID
This patch adds support for TSO using IPv4 headers with a fixed IP ID
field. This is meant to allow us to do a lossless GRO in the case of TCP
flows that use a fixed IP ID such as those that convert IPv6 header to IPv4
headers.
In addition I am adding a feature that for now I am referring to TSO with
IP ID mangling. Basically when this flag is enabled the device has the
option to either output the flow with incrementing IP IDs or with a fixed
IP ID regardless of what the original IP ID ordering was. This is useful
in cases where the DF bit is set and we do not care if the original IP ID
value is maintained.

====================
devlink + mlxsw: add support for config and control of shared buffers
ASICs implement shared buffer for packet forwarding purposes and enable
flexible partitioning of the shared buffer for different flows and ports,
enabling non-blocking progress of different flows as well as separation
of lossy traffic from loss-less traffic when using Per-Priority Flow
Control (PFC). The shared buffer optimizes the buffer utilization for better
absorption of packet bursts.
This patchset implements API which is based on the model SAI uses. That is
aligned with multiple ASIC vendors so this API should be vendor neutral.

devlink: implement shared buffer occupancy monitoring interface
User needs to monitor shared buffer occupancy. For that, he issues a
snapshot command in order to instruct hardware to catch current and
maximal occupancy values, and clear command in order to clear the
historical maximal values.
Also port-pool and tc-pool-bind command response messages are extended to
carry occupancy values.

shared buffer - attributes are size, number of pools and TCs
pool - chunk of sharedbuffer definition, it has some size and either
static or dynamic threshold
port pool threshold - to set per-port threshold for each pool
port tc threshold bind - to bind port and TC to specified pool
with threshold.

In other thread, mwifiex_remove_card() waits on semaphore until the
firmware download fails. This wait is not necessary and may result in
invalid adapter access.
This patch uses down_trylock to return immediately so that hang issue

sctp: delay calls to sk_data_ready() as much as possible
Currently processing of multiple chunks in a single SCTP packet leads to
multiple calls to sk_data_ready, causing multiple wake up signals which
are costy and doesn't make it wake up any faster.
With this patch it will note that the wake up is pending and will do it
before leaving the state machine interpreter, latest place possible to
do it realiably and cleanly.
Note that sk_data_ready events are not dependent on asocs, unlike waking
up writers.

It wastes space and gets worse as we add new flags, so convert bit-wide

Currently it already saves 4 bytes in sctp_sock, which are left as holes

Xin Long says:
====================
bridge: support sending rntl info when we set attributes through sysfs/ioctl
This patchset is used to support sending rntl info to user in some places,
and ensure that whenever those attributes change internally or from sysfs,
that a netlink notification is sent out to listeners.
It also make some adjustment in bridge sysfs so that we can implement this
easily.
I've done some tests on this patchset, like:
[br_sysfs]
1. change all the attribute values of br or brif:
$ echo $value > /sys/class/net/br0/bridge/{*}
$ echo $value > /sys/class/net/br0/brif/eth1/{*}
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
[br_ioctl]
1. in bridge-utils package, do some changes in br_set, let brctl command
use ioctl to set attribute:
if ((ret = set_sysfs(path, value)) < 0) { -->
if (1) {
$ brctl set*
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
This test covers all the attributes that brctl and sysfs support to set.

ipv6, token: allow for clearing the current device token
The original tokenized iid support implemented via f53adae4eae5 ("net: ipv6:
add tokenized interface identifier support") didn't allow for clearing a
device token as it was intended that this addressing mode was the only one
active for globally scoped IPv6 addresses. Later we relaxed that restriction
via 617fe29d45bd ("net: ipv6: only invalidate previously tokenized addresses"),
and we should also allow for clearing tokens as there's no good reason why
it shouldn't be allowed.
Fixes: 617fe29d45bd ("net: ipv6: only invalidate previously tokenized addresses")

net: ethernet: stmmac: GMAC4.xx: Fix TX descriptor preparation
On GMAC4.xx each descriptor contains 2 buffers of 16KB (each).
Initially, those 2 buffers was filled in dwmac4_rd_prepare_tx_desc but
it is actually not needed. Indeed, stmmac driver supports frame up to
9000 bytes (jumbo). So only one buffer is needed.

udp: do not expect udp headers in recv cmsg IP_CMSG_CHECKSUM
On udp sockets, recv cmsg IP_CMSG_CHECKSUM returns a checksum over
the packet payload. Since commit e6afc8ace6dd pulled the headers,
taking skb->data as the start of transport header is incorrect. Use
the transport header pointer.
Also, when peeking at an offset from the start of the packet, only
return a checksum from the start of the peeked data. Note that the
cmsg does not subtract a tail checkum when reading truncated data.

netfilter: x_tables: do compat validation via translate_table
This looks like refactoring, but its also a bug fix.
Problem is that the compat path (32bit iptables, 64bit kernel) lacks a few
sanity tests that are done in the normal path.
For example, we do not check for underflows and the base chain policies.
While its possible to also add such checks to the compat path, its more
copy&pastry, for instance we cannot reuse check_underflow() helper as
e->target_offset differs in the compat case.
Other problem is that it makes auditing for validation errors harder; two
places need to be checked and kept in sync.
At a high level 32 bit compat works like this:
1- initial pass over blob:
validate match/entry offsets, bounds checking
lookup all matches and targets
do bookkeeping wrt. size delta of 32/64bit structures
assign match/target.u.kernel pointer (points at kernel
implementation, needed to access ->compatsize etc.)
2- allocate memory according to the total bookkeeping size to
contain the translated ruleset
3- second pass over original blob:
for each entry, copy the 32bit representation to the newly allocated
memory. This also does any special match translations (e.g.
adjust 32bit to 64bit longs, etc).
4- check if ruleset is free of loops (chase all jumps)
5-first pass over translated blob:
call the checkentry function of all matches and targets.
The alternative implemented by this patch is to drop steps 3&4 from the
compat process, the translation is changed into an intermediate step
rather than a full 1:1 translate_table replacement.
In the 2nd pass (step #3), change the 64bit ruleset back to a kernel
representation, i.e. put() the kernel pointer and restore ->u.user.name .
This gets us a 64bit ruleset that is in the format generated by a 64bit
iptables userspace -- we can then use translate_table() to get the
'native' sanity checks.
This has two drawbacks:
1. we re-validate all the match and target entry structure sizes even
though compat translation is supposed to never generate bogus offsets.
2. we put and then re-lookup each match and target.
THe upside is that we get all sanity tests and ruleset validations
provided by the normal path and can remove some duplicated compat code.
iptables-restore time of autogenerated ruleset with 300k chains of form
-A CHAIN0001 -m limit --limit 1/s -j CHAIN0002
-A CHAIN0002 -m limit --limit 1/s -j CHAIN0003
shows no noticeable differences in restore times:
old: 0m30.796s
new: 0m31.521s
64bit: 0m25.674s

netfilter: x_tables: check standard target size too
We have targets and standard targets -- the latter carries a verdict.
The ip/ip6tables validation functions will access t->verdict for the
standard targets to fetch the jump offset or verdict for chainloop
detection, but this happens before the targets get checked/validated.
Thus we also need to check for verdict presence here, else t->verdict
can point right after a blob.

netfilter: x_tables: don't move to non-existent next rule
Ben Hawkes says:
In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it
is possible for a user-supplied ipt_entry structure to have a large
next_offset field. This field is not bounds checked prior to writing a
counter value at the supplied offset.
Base chains enforce absolute verdict.
User defined chains are supposed to end with an unconditional return,
xtables userspace adds them automatically.
But if such return is missing we will move to non-existent next rule.

====================
DSA refactoring: set 1
There has been a long running effort to refractor DSA probing to make
the switches true linux devices. Here are a small collection of
patches moving in this direction. Most have been seen before.
We take a little step forward by passing the dsa device point to the
driver, thus allowing it to perform resource allocations using the
normal mechanisms. This device structure will later be replaced by the
devices own device structure.
Future patches will add a true driver probe function, so we rename the
current probe function, cleaning up the namespace.
phys_port_mask continually confuses me, thinking it is about PHYs. But
it is actually about ports enabled to the outside world. So rename it to
enabled_port_mask.
Lots more patches yet to follow, this is just doing some ground work.

====================
net: mediatek: make the driver pass stress tests
While testing the driver we managed to get the TX path to stall and fail
to recover. When dual MAC support was added to the driver, the whole queue
stop/wake code was not properly adapted. There was also a regression in the
locking of the xmit function. The fact that watchdog_timeo was not set and
that the tx_timeout code failed to properly reset the dma, irq and queue
just made the mess complete.
This series make the driver pass stress testing. With this series applied
the testbed has been running for several days and still has not locked up.
We have a second setup that has a small hack patch applied to randomly stop
irqs and/or one of the queues and successfully manages to recover from these
simulated tx stalls.

net: mediatek: do not set the QID field in the TX DMA descriptors
The QID field gets set to the mac id. This made the DMA linked list queue
the traffic of each MAC on a different internal queue. However during long
term testing we found that this will cause traffic stalls as the multi
queue setup requires a more complete initialisation which is not part of
the upstream driver yet.
This patch removes the code setting the QID field, resulting in all
traffic ending up in queue 0 which works without any special setup.

Merge branch 'rprpc-2nd-rewrite-part-1'
David Howells says:
====================
RxRPC: 2nd rewrite part 1
Okay, I'm in the process of rewriting the RxRPC rewrite. The primary aim of
this second rewrite is to strictly control the number of active connections we
know about and to get rid of connections we don't need much more quickly.
On top of this, there are fixes to the protocol handling which will all occur
in later parts.
Here's the first set of patches from the second go, aimed at net-next. These
are all fixes and cleanups preparatory to the main event.
Notable parts of this set include:
(1) A fix for the AFS filesystem to wait for outstanding calls to complete
before closing the RxRPC socket.
(2) Differentiation of local and remote abort codes. At a future point
userspace will get to see this via control message data on recvmsg().
(3) Absorb the rxkad module into the af_rxrpc module to prevent a dependency
loop.
(4) Create a null security module and unconditionalise calls into the
security module that's in force (there will always be a security module
applied to a connection, even if it's just the null one).

rxrpc: Absorb the rxkad security module
Absorb the rxkad security module into the af_rxrpc module so that there's
only one module file. This avoids a circular dependency whereby rxkad pins
af_rxrpc and cached connections pin rxkad but can't be manually evicted
(they will expire eventually and cease pinning).
With this change, af_rxrpc can just be unloaded, despite having cached
connections.

rxrpc: Differentiate local and remote abort codes in structs
In the rxrpc_connection and rxrpc_call structs, there's one field to hold
the abort code, no matter whether that value was generated locally to be
sent or was received from the peer via an abort packet.
Split the abort code fields in two for cleanliness sake and add an error
field to hold the Linux error number to the rxrpc_call struct too
(sometimes this is generated in a context where we can't return it to
userspace directly).
Furthermore, add a skb mark to indicate a packet that caused a local abort
to be generated so that recvmsg() can pick up the correct abort code. A
future addition will need to be to indicate to userspace the difference
between aborts via a control message.

afs: Wait for outstanding async calls before closing rxrpc socket
The afs filesystem needs to wait for any outstanding asynchronous calls

This may occur if the module is removed too quickly after unmounting all
filesystems. This will produce an error report that looks like:

net: fix udp pull header breakage
Commit e6afc8ace6dd ("udp: remove headers from UDP packets before
queueing") modified udp receive processing to pull headers before
enqueue and to not expect them on dequeue.
The patch missed protocols on top of udp with in-kernel
implementations that have their own skb_recv_datagram calls and
dequeue logic. Modify these datapaths to also no longer expect
a udp header at skb->data.
Sunrpc and rxrpc are the only two protocols that call this
function and contain references to udphr (some others, like tipc,
are based on encap_rcv, which acts before enqueue, before the
the header pull).

net: ipv4: Consider failed nexthops in multipath routes
Multipath route lookups should consider knowledge about next hops and not
select a hop that is known to be failed.
Example:
[h2] [h3] 15.0.0.5
| |
3| 3|
[SP1] [SP2]--+
1 2 1 2
| | /-------------+ |
| \ / |
| X |
| / \ |
| / \---------------\ |
1 2 1 2
12.0.0.2 [TOR1] 3-----------------3 [TOR2] 12.0.0.3
4 4
\ /
\ /
\ /
-------| |-----/
1 2
[TOR3]
3|
|
[h1] 12.0.0.1
host h1 with IP 12.0.0.1 has 2 paths to host h3 at 15.0.0.5:
root@h1:~# ip ro ls
...
12.0.0.0/24 dev swp1 proto kernel scope link src 12.0.0.1
15.0.0.0/16
nexthop via 12.0.0.2 dev swp1 weight 1
nexthop via 12.0.0.3 dev swp1 weight 1
...
If the link between tor3 and tor1 is down and the link between tor1
and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups
in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and
ssh 15.0.0.5 gets the other. Connections that attempt to use the
12.0.0.2 nexthop fail since that neighbor is not reachable:
root@h1:~# ip neigh show
...
12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE
12.0.0.2 dev swp1 FAILED
...
The failed path can be avoided by considering known neighbor information
when selecting next hops. If the neighbor lookup fails we have no
knowledge about the nexthop, so give it a shot. If there is an entry
then only select the nexthop if the state is sane. This is similar to
what fib_detect_death does.
To maintain backward compatibility use of the neighbor information is
based on a new sysctl, fib_multipath_use_neigh.

drivers: net: cpsw: fix port_mask parameters in ale calls
ALE APIs expect to receive port masks as input values for arguments
port_mask, untag, reg_mcast, unreg_mcast. But there are few places in
code where port masks are passed left-shifted by cpsw_priv->host_port,
like below:
cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan,
ALE_ALL_PORTS << priv->host_port,
ALE_ALL_PORTS << priv->host_port, 0, 0);
and cpsw is still working just because priv->host_port == 0
and has never ever been changed.
Hence, fix port_mask parameters in ALE APIs calls and drop
"<< priv->host_port" from all places where it's used to
shift valid port mask.

bpf: simplify verifier register state assignments
verifier is using the following structure to track the state of registers:
struct reg_state {
enum bpf_reg_type type;
union {
int imm;
struct bpf_map *map_ptr;
};
};
and later on in states_equal() does memcmp(&old->regs[i], &cur->regs[i],..)
to find equivalent states.
Throughout the code of verifier there are assignements to 'imm' and 'map_ptr'
fields and it's not obvious that most of the assignments into 'imm' don't
need to clear extra 4 bytes (like mark_reg_unknown_value() does) to make sure
that memcmp doesn't go over junk left from 'map_ptr' assignment.
Simplify the code by converting 'int' into 'long'

ibmvnic: Enable use of multiple tx/rx scrqs
Enables the use of multiple transmit and receive scrqs allowing the ibmvnic
driver to take advantage of multiqueue functionality. To achieve this, the
driver must implement the process of negotiating the maximum number of
queues allowed by the server. Initially, the driver will attempt to login
with the maximum number of tx and rx queues supported by the server. If
the server fails to allocate the requested number of scrqs, it will return
partial success in the login response. In this case, we must reinitiate
the login process from the request capabilities stage and attempt to login
requesting fewer scrqs.

bpf, verifier: further improve search pruning
The verifier needs to go through every path of the program in
order to check that it terminates safely, which can be quite a
lot of instructions that need to be processed f.e. in cases with
more branchy programs. With search pruning from f1bca824dabb ("bpf:
add search pruning optimization to verifier") the search space can
already be reduced significantly when the verifier detects that
a previously walked path with same register and stack contents
terminated already (see verifier's states_equal()), so the search
can skip walking those states.
When working with larger programs of > ~2000 (out of max 4096)
insns, we found that the current limit of 32k instructions is easily
hit. For example, a case we ran into is that the search space cannot
be pruned due to branches at the beginning of the program that make
use of certain stack space slots (STACK_MISC), which are never used
in the remaining program (STACK_INVALID). Therefore, the verifier
needs to walk paths for the slots in STACK_INVALID state, but also
all remaining paths with a stack structure, where the slots are in
STACK_MISC, which can nearly double the search space needed. After
various experiments, we find that a limit of 64k processed insns is
a more reasonable choice when dealing with larger programs in practice.
This still allows to reject extreme crafted cases that can have a
much higher complexity (f.e. > ~300k) within the 4096 insns limit
due to search pruning not being able to take effect.
Furthermore, we found that a lot of states can be pruned after a
call instruction, f.e. we were able to reduce the search state by
~35% in some cases with this heuristic, trade-off is to keep a bit
more states in env->explored_states. Usually, call instructions
have a number of preceding register assignments and/or stack stores,
where search pruning has a better chance to suceed in states_equal()
test. The current code marks the branch targets with STATE_LIST_MARK
in case of conditional jumps, and the next (t + 1) instruction in
case of unconditional jump so that f.e. a backjump will walk it. We
also did experiments with using t + insns[t].off + 1 as a marker in
the unconditionally jump case instead of t + 1 with the rationale
that these two branches of execution that converge after the label
might have more potential of pruning. We found that it was a bit
better, but not necessarily significantly better than the current
state, perhaps also due to clang not generating back jumps often.
Hence, we left that as is for now.

====================
MTU/buffer reconfig changes
I re-discussed MPLS/MTU internally, dropped it from the patch 1,
re-tested everything, found out I forgot about debugfs pointers,
fixed that as well.
v5:
- don't reserve space in RX buffers for MPLS label stack
(patch 1);
- fix debugfs pointers to ring structures (patch 5).
v4:
- cut down on unrelated patches;
- don't "close" the device on error path.
--- v4 cover letter
Previous series included some not entirely related patches,
this one is cut down. Main issue I'm trying to solve here
is that .ndo_change_mtu() in nfpvf driver is doing full
close/open to reallocate buffers - which if open fails
can result in device being basically closed even though
the interface is started. As suggested by you I try to move
towards a paradigm where the resources are allocated first
and the MTU change is only done once I'm certain (almost)
nothing can fail. Almost because I need to communicate
with FW and that can always time out.
Patch 1 fixes small issue. Next 10 patches reorganize things
so that I can easily allocate new rings and sets of buffers
while the device is running. Patches 13 and 15 reshape the
.ndo_change_mtu() and ethtool's ring-resize operation into
desired form.

nfp: convert .ndo_change_mtu() to prepare/commit paradigm
When changing MTU on running device first allocate new rings
and buffers and once it succeeds proceed with changing MTU.
Allocation of new rings is not really necessary for this
operation - it's done to keep the code simple and because
size of the extra ring memory is quite small compared to
the size of buffers.
Operation can still fail midway through if FW communication
times out. In that case we retry with old MTU (rings).

Read side should read them, if there is any. If there is none, skbs
should be dropped by hdev->flush. But this happens only if the device
is HCI_UP, i.e. hdev->power_on work was triggered already. When it was
not, skbs stay allocated in the queue when /dev/vhci is closed. So
purge the queue in ->release.
Program to reproduce:
#include <err.h>
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <sys/uio.h>
int main()
{
char buf[] = { 0xff, 0 };
struct iovec iov = {
.iov_base = buf,
.iov_len = sizeof(buf),
};
int fd;
while (1) {
fd = open("/dev/vhci", O_RDWR);
if (fd < 0)
err(1, "open");
usleep(50);
if (writev(fd, &iov, 1) < 0)
err(1, "writev");
usleep(50);
close(fd);
}
return 0;
}

Bluetooth: vhci: fix open_timeout vs. hdev race
Both vhci_get_user and vhci_release race with open_timeout work. They
both contain cancel_delayed_work_sync, but do not test whether the
work actually created hdev or not. Since the work can be in progress
and _sync will wait for finishing it, we can have data->hdev allocated
when cancel_delayed_work_sync returns. But the call sites do 'if
(data->hdev)' *before* cancel_delayed_work_sync.
As a result:
* vhci_get_user allocates a second hdev and puts it into
data->hdev. The former is leaked.
* vhci_release does not release data->hdev properly as it thinks there
is none.
Fix both cases by moving the actual test *after* the call to
cancel_delayed_work_sync.
This can be hit by this program:
#include <err.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>
int main(int argc, char **argv)
{
int fd;
srand(time(NULL));
while (1) {
const int delta = (rand() % 200 - 100) * 100;
fd = open("/dev/vhci", O_RDWR);
if (fd < 0)
err(1, "open");
usleep(1000000 + delta);
close(fd);
}
return 0;
}

====================
10GbE Intel Wired LAN Driver Updates 2016-04-07
This series contains updates to ixgbe and ixgbevf.
This entire series (except for one patch from Alex) comes from Mark and
is mainly to add support for our new MAC (x550em_a).
So let's get Alex's patch out of the way first before we cover Mark's
many changes. Alex does his enable bulk free in transmit cleanup for
ixgbe and ixgbevf, like his has done for all of our other drivers.
First Mark cleans up registers that were not being used, so do some
house cleaning. Then to avoid casting lan_id and func fields, just
make them u8 since they only hold small values anyways. Found and
fixed an issue where on read operations it could be possible to
modify locations beyond the length passed in, so change the check
to round up in the same way. Cleaned up the interface for issuing
firmware commands to use a void * instead of a u32 * which eliminates
a number of casts. Added support for the new MAC and provided method
pointers and use them to access IOSF-attached devices, since the
new MAC will also need a new access method. Added support for SFPs
with an external retimer and for an SGMII backplane interface.

====================
allow bpf attach to tracepoints
Hi Steven, Peter,
v1->v2: addressed Peter's comments:
- fixed wording in patch 1, added ack
- refactored 2nd patch into 3:
2/10 remove unused __perf_addr macro which frees up
an argument in perf_trace_buf_submit
3/10 split perf_trace_buf_prepare into alloc and update parts, so that bpf
programs don't have to pay performance penalty for update of struct trace_entry
which is not going to be accessed by bpf
4/10 actual addition of bpf filter to perf tracepoint handler is now trivial
and bpf prog can be used as proper filter of tracepoints
v1 cover:
last time we discussed bpf+tracepoints it was a year ago [1] and the reason
we didn't proceed with that approach was that bpf would make arguments
arg1, arg2 to trace_xx(arg1, arg2) call to be exposed to bpf program
and that was considered unnecessary extension of abi. Back then I wanted
to avoid the cost of buffer alloc and field assign part in all
of the tracepoints, but looks like when optimized the cost is acceptable.
So this new apporach doesn't expose any new abi to bpf program.
The program is looking at tracepoint fields after they were copied
by perf_trace_xx() and described in /sys/kernel/debug/tracing/events/xxx/format
We made a tool [2] that takes arguments from /sys/.../format and works as:
$ tplist.py -v random:urandom_read
int got_bits;
int pool_left;
int input_left;
Then these fields can be copy-pasted into bpf program like:
struct urandom_read {
__u64 hidden_pad;
int got_bits;
int pool_left;
int input_left;
};
and the program can use it:
SEC("tracepoint/random/urandom_read")
int bpf_prog(struct urandom_read *ctx)
{
return ctx->pool_left > 0 ? 1 : 0;
}
This way the program can access tracepoint fields faster than
equivalent bpf+kprobe program, which is the main goal of these patches.
Patch 1-4 are simple changes in perf core side, please review.
I'd like to take the whole set via net-next tree, since the rest of
the patches might conflict with other bpf work going on in net-next
and we want to avoid cross-tree merge conflicts.
Alternatively we can put patches 1-4 into both tip and net-next.
Patch 9 is an example of access to tracepoint fields from bpf prog.
Patch 10 is a micro benchmark for bpf+kprobe vs bpf+tracepoint.
Note that for actual tracing tools the user doesn't need to
run tplist.py and copy-paste fields manually. The tools do it
automatically. Like argdist tool [3] can be used as:
$ argdist -H 't:block:block_rq_complete():u32:nr_sector'
where 'nr_sector' is name of tracepoint field taken from
/sys/kernel/debug/tracing/events/block/block_rq_complete/format
and appropriate bpf program is generated on the fly.

perf, bpf: allow bpf programs attach to tracepoints
introduce BPF_PROG_TYPE_TRACEPOINT program type and allow it to be attached
to the perf tracepoint handler, which will copy the arguments into
the per-cpu buffer and pass it to the bpf program as its first argument.
The layout of the fields can be discovered by doing
'cat /sys/kernel/debug/tracing/events/sched/sched_switch/format'
prior to the compilation of the program with exception that first 8 bytes
are reserved and not accessible to the program. This area is used to store
the pointer to 'struct pt_regs' which some of the bpf helpers will use:
+---------+
| 8 bytes | hidden 'struct pt_regs *' (inaccessible to bpf program)
+---------+
| N bytes | static tracepoint fields defined in tracepoint/format (bpf readonly)
+---------+
| dynamic | __dynamic_array bytes of tracepoint (inaccessible to bpf yet)
+---------+
Not that all of the fields are already dumped to user space via perf ring buffer
and broken application access it directly without consulting tracepoint/format.
Same rule applies here: static tracepoint fields should only be accessed
in a format defined in tracepoint/format. The order of fields and
field sizes are not an ABI.

perf: optimize perf_fetch_caller_regs
avoid memset in perf_fetch_caller_regs, since it's the critical path of all tracepoints.
It's called from perf_sw_event_sched, perf_event_task_sched_in and all of perf_trace_##call
with this_cpu_ptr(&__perf_regs[..]) which are zero initialized by perpcu init logic and
subsequent call to perf_arch_fetch_caller_regs initializes the same fields on all archs,
so we can safely drop memset from all of the above cases and move it into
perf_ftrace_function_call that calls it with stack allocated pt_regs.

tipc: stricter filtering of packets in bearer layer
Resetting a bearer/interface, with the consequence of resetting all its
pertaining links, is not an atomic action. This becomes particularly
evident in very large clusters, where a lot of traffic may happen on the
remaining links while we are busy shutting them down. In extreme cases,
we may even see links being re-created and re-established before we are
finished with the job.
To solve this, we now introduce a solution where we temporarily detach
the bearer from the interface when the bearer is reset. This inhibits
all packet reception, while sending still is possible. For the latter,
we use the fact that the device's user pointer now is zero to filter out
which packets can be sent during this situation; i.e., outgoing RESET
messages only. This filtering serves to speed up the neighbors'
detection of the loss event, and saves us from unnecessary probing.

tipc: eliminate buffer leak in bearer layer
When enabling a bearer we create a 'neigbor discoverer' instance by
calling the function tipc_disc_create() before the bearer is actually
registered in the list of enabled bearers. Because of this, the very
first discovery broadcast message, created by the mentioned function,
is lost, since it cannot find any valid bearer to use. Furthermore,
the used send function, tipc_bearer_xmit_skb() does not free the given
buffer when it cannot find a bearer, resulting in the leak of exactly
one send buffer each time a bearer is enabled.
This commit fixes this problem by introducing two changes:
1) Instead of attemting to send the discovery message directly, we let
tipc_disc_create() return the discovery buffer to the calling
function, tipc_enable_bearer(), so that the latter can send it
when the enabling sequence is finished.
2) In tipc_bearer_xmit_skb(), as well as in the two other transmit
functions at the bearer layer, we now free the indicated buffer or
buffer chain when a valid bearer cannot be found.

====================
udp: GRO in UDP sockets
This patch set adds GRO functions (gro_receive and gro_complete) to UDP
sockets and removes udp_offload infrastructure.
Add GRO functions (gro_receive and gro_complete) to UDP sockets. In
udp_gro_receive and udp_gro_complete a socket lookup is done instead of
looking up the port number in udp_offloads. If a socket is found and
there are GRO functions for it then those are called. This feature
allows binding GRO functions to more than just a port number.
Eventually, we will be able to use this technique to allow application
defined GRO for an application protocol by attaching BPF porgrams to UDP
sockets for doing GRO.
In order to implement these functions, we added exported
udp6_lib_lookup_skb and udp4_lib_lookup_skb functions in ipv4/udp.c and
ipv6/udp.c. Also, inet_iif and references to skb_dst() were changed to
check that dst is set in skbuf before derefencing. In the GRO path there
is now a UDP socket lookup performed before dst is set, to the get the
device in that case we simply use skb->dev.
Tested:
Ran various combinations of VXLAN and GUE TCP_STREAM and TCP_RR tests.
Did not see any material regression.

udp: Add GRO functions to UDP socket
This patch adds GRO functions (gro_receive and gro_complete) to UDP
sockets. udp_gro_receive is changed to perform socket lookup on a
packet. If a socket is found the related GRO functions are called.
This features obsoletes using UDP offload infrastructure for GRO
(udp_offload). This has the advantage of not being limited to provide
offload on a per port basis, GRO is now applied to whatever individual
UDP sockets are bound to. This also allows the possbility of
"application defined GRO"-- that is we can attach something like
a BPF program to a UDP socket to perfrom GRO on an application
layer protocol.

net: introduce lockdep_is_held and update various places to use it
The socket is either locked if we hold the slock spin_lock for
lock_sock_fast and unlock_sock_fast or we own the lock (sk_lock.owned
!= 0). Check for this and at the same time improve that the current
thread/cpu is really holding the lock.

sock: fix lockdep annotation in release_sock
During release_sock we use callbacks to finish the processing
of outstanding skbs on the socket. We actually are still locked,
sk_locked.owned == 1, but we already told lockdep that the mutex
is released. This could lead to false positives in lockdep for
lockdep_sock_is_held (we don't hold the slock spinlock during processing
the outstanding skbs).
I took over this patch from Eric Dumazet and tested it.

mwifiex: AMSDU Rx frame handling in AP mode
This patch processes sub AMSDU frame received in AP mode.
If a packet is multicast/broadcast, it is sent to kernel/upper
layer as well as queued back to AP TX queue so that it can be
sent to other associated stations.
If a packet is unicast and RA is present in associated station list,
it is again requeued into AP TX queue.
If a packet is unicast and RA is not in associated station list,
packet is forwarded to kernel to handle routing logic.

iwl4965: Fix more memory leaks in __il4965_up()
In some of the non-success return paths, the memory allocated by
iwl4965_sta_alloc_lq() in iwl4965_alloc_bcast_station() is not freed.
In particular:
- if the card isn't ready after il4965_prepare_card_hw()
- if the card is hardware-rfkilled
In the hardware rfkilled path, the driver enables the rfkill
interrupt. When the card is unrfkilled and this interrupt is raised
we end up calling il4965_bg_restart() which calls __il4965_up() which
calls iwl4965_alloc_bcast_station() again.

iwl4965: Fix a null pointer dereference in il_tx_queue_free and il_cmd_queue_free
If "txq->cmd = kzalloc(...)" in il_tx_queue_init fails,
"kfree(txq->cmd[i])" in il_tx_queue_free and il_cmd_queue_free
in iwl4965_hw_txq_ctx_free will causes a null pointer dereference,
because txq->cmd is NULL at that time.
This patch fixes this problem by adding a if-check before kfree.
To avoid double free in il_tx_queue_free and il_cmd_queue_free
caused by the fixing, txq->meta and txq->cmd in error handling code
of il_tx_queue_init are assigned null values.
Otherwise, a double free will occur.
This patch has been tested in real device, and it actually fixes the bug.

tcp/dccp: fix inet_reuseport_add_sock()
David Ahern reported panics in __inet_hash() caused by my recent commit.
The reason is inet_reuseport_add_sock() was still using
sk_nulls_for_each_rcu() instead of sk_for_each_rcu().
SO_REUSEPORT enabled listeners were causing an instant crash.
While chasing this bug, I found that I forgot to clear SOCK_RCU_FREE
flag, as it is inherited from the parent at clone time.

1GbE Intel Wired LAN Driver Updates 2016-04-06
This series contains updates to e1000, e1000e, igb and Kconfig.
Alex fixes igb where we were casting the MAC address as __beXX and then
passing it into le32_to_cpu, when we could simply cast as __lexx to
maintain consistency since it is already little endian. Then enabled
bulk free in transmit cleanup for igb.
John Holland enables igb to pickup the MAC address from a device tree
blob when CONFIG_OF has been enabled.
Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where
the data byte appeared duplicated.
Stefan fixes up e1000 and e1000e ethtool offline tests which were calling
dev_close() which causes IFF_UP to be cleared which removes teh interface
routes and some addresses, so use ndo_stop() instead.
Jiri Benc cleans up some old links in the Kconfig for Intel drivers where
we referred to a URL which is no longer valid. I am so glad Jiri has the
time in his day to spend clicking on and testing all the URL links in the
the kernel.
Arika Chen reverts the addition of a 'rtnl_unlock()' which had a unmatched
'rtnl_lock()' call before it.

Jesse moves a local variable deeper into the depths of the driver
where the light is low and the context is great. Then cleaned up
the tx_ring argument since it was not making good arguments. Improved
performance by not "checking for FCoE" by re-ordering the FCoE checks.

Just keep a generic pointer to http://support.intel.com. Hopefully, this one
will have a longer live. It still works, at least.
Furthermore, remove a link to "the latest Intel PRO/100 network driver for

it offers is from 2006, anyway.

e1000: call ndo_stop() instead of dev_close() when running offline selftest
Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

====================
mlxsw: Introduce support for Data Center Bridging
Ido says:
This patchset introduces support for Quality of Service (QoS) as part of the
IEEE Data Center Bridiging (DCB) standards.
Patches 1-9 do the required device initialization. Specifically, patches 1-6
initialize the ports' headroom buffers, which are used at ingress to store
incoming packets while they go through the switch's pipeline. Patches 7-9
complete them by initializing the egress scheduling.
The pipeline mentioned above determines the packet's egress port(s) and
traffic class. Ideally, once out of the pipeline the packet moves to the
switch's shared buffer (to be introduced in Jiri's patchset, currently
default values are used) and scheduled for transmission according to its
traffic class. The egress scheduling is configured according to the 802.1Qaz
standard, which is part of the DCB infrastructure supported by Linux. This
is introduced in patches 10-12.
Even after going through the pipeline packets are not always eligible to
enter the shared buffer. This is determined by the amount of available space
and the quotas associated with the packet. However, if flow control is
enabled and the packet is associated with the lossless flow, then it will
stay in the headroom and won't be discarded. This is introduced in patches
13-17.
Please check individual commit messages for more info, as I tried to keep
them pretty detailed.

mlxsw: spectrum: Add IEEE 802.1Qbb PFC support
Implement the appropriate DCB ops and allow a user to configure certain
traffic classes as lossless.
The operation configures PFC for both the egress (respecting PFC frames)
and ingress (sending PFC frames) parts of the port.
At egress, when a PFC frame is received for a PFC enabled priority, then
all the priorities mapped to the same TC are stopped.
At ingress, the priority group (PG) buffers to which the enabled PFC
priorities are mapped are configured to be lossless. PFC frames will be
transmitted when the Xoff threshold is crossed.
The user-supplied delay parameter is used to determine the PG's size
according to the following formula:
PG_SIZE = PG_SIZE_LOSSY + delay * CELL_FACTOR + MTU
In the worst case scenario the delay will be made up of packets that
are all of size CELL_SIZE + 1, which means each packet will require
almost twice its true size when buffered in the switch. We therefore
multiply this value by the "cell factor", which is close to 2.
Another MTU is added in case the transmitting host already started

mlxsw: spectrum: Add support for PAUSE frames
When a packet ingress the switch it's placed in its assigned priority
group (PG) buffer in the port's headroom buffer while it goes through
the switch's pipeline. After going through the pipeline - which
determines its egress port(s) and traffic class - it's moved to the
switch's shared buffer awaiting transmission.
However, some packets are not eligible to enter the shared buffer due to
exceeded quotas or insufficient space. Marking their associated PGs as
lossless will cause the packets to accumulate in the PG buffer. Another
reason for packets accumulation are complicated pipelines (e.g.
involving a lot of ACLs).
To prevent packets from being dropped a user can enable PAUSE frames on
the port. This will mark all the active PGs as lossless and set their
size according to the maximum delay, as it's not configured by user.
+----------------+ +

| | |
| | |
| | |
Xon/Xoff threshold +----------------+ +
| | |
| | | 2 * MTU
| | |
+----------------+ +
The delay (612 [Cells]) was calculated according to worst-case scenario
involving maximum MTU and 100m cables.
After marking the PGs as lossless the device is configured to respect
incoming PAUSE frames (Rx PAUSE) and generate PAUSE frames (Tx PAUSE)
according to user's settings.
Whenever the port's headroom configuration changes we take into account
the PAUSE configuration, so that we correctly set the PG's type (lossy /
lossless), size and threshold. This can happen when:
a) The port's MTU changes, as it directly affects the PG's size.
b) A PG is created following user configuration, by binding a priority
to it.
Note that the relevant SUPPORTED flags were already mistakenly set by
the driver before this commit.

mlxsw: spectrum: Initialize egress scheduling
Before introducing support for DCB ops we should first make sure we
initialize the relevant parts in the device correctly. Specifically, the
egress scheduling.
The device supports a superset of the 802.1Qaz standard with 4 hierarchy
levels that can be linked to each other in multiple ways and with
different transmission selection algorithms (TSA) employed between them.
However, since we only intend to support the 802.1Qaz standard we
flatten the hierarchies and let the user configure via DCB ops the TSA
and max rate shaper at the subgroup hierarchy (see figure below) and the
mapping between switch priority to traffic class. By default, all switch
priorities are mapped to traffic class 0, strict priority is employed
and max shaper is disabled.
Default configuration:
switch priority 0 ... switch priority 7

mlxsw: spectrum: Correctly configure headroom size
When packets ingress the switch they are assigned a switch priority and
directed to the corresponding priority group (PG) buffer in the port's
headroom buffer.
Since we now map all switch priorities to priority group 0 (PG0) by
default, there is no need to allocate the other priority groups during
initialization. The only exception is PG9, which is used for control
traffic.
At minimum, the PG should be able to store the currently classified
packet (pipeline latency isn't 0) and also the packets arriving during
the classification time. However, an incoming packet will not be
buffered if there is no available MTU-sized buffer space for storing it.
The buffer needed to accommodate for pipeline latency is variable and
needs to take into account both the current link speed and current
latency of the pipeline, which is time-dependent. Testing showed that
setting the PG's size to twice the current MTU is optimal.
Since PG9 is used strictly for control packets and not subject to flow
control, we are not going to resize it according to user configuration,
so we simply set it according to worst case scenario, which is twice the
maximum MTU.
In any case, later patches in the series will allow a user to direct
lossless flows to other PGs than PG0 and set their size to accommodate
for round-trip propagation delay.
The above change also requires us to resize the PG buffer whenever the
port's MTU is changed.

mlxsw: spectrum: Map all switch priorities to priority group 0
During transmission, the skb's priority is used to map the skb to a
traffic class, where the idea is to group priorities with similar
characteristics (e.g. lossy, lossless) to the same traffic class. By
default, all priorities are mapped to traffic class 0.
In the device, we model the skb's priority as the switch priority, which
is assigned to a packet according to its PCP value and ingress port
(untagged packets are assigned the port's default switch priority - 0).
At ingress, the packet is directed to a priority group (PG) buffer in
the port's headroom buffer according to the packet's switch priority and
switch priority to buffer mapping.
While it's possible to configure the egress mapping between skb's
priority (switch priority) and traffic class, there is no mechanism to
configure the ingress mapping to a PG.
In order to keep things simple and since grouping certain priorities into
a traffic class at egress also implies they should be grouped the same
at ingress, treat a PG as the ingress counterpart of an egress traffic
class.
Having established the above, during initialization map all the switch
priorities to PG0 in accordance with the Linux defaults for traffic
class mapping.

behaviour is inconsistent.

Anjali enables geneve receive offload for XL710/X710 devices.
Mitch cleans up unused variable in i40e_vc_get_vf_resources_msg().
Fixed the driver to actually be able to adjust VLAN tagging features
through ethtool, as expected. Fixed a problem where VF resets would
get lost by the PF preventing the VF driver from initializing. Also
put users mind at ease by lowering some message levels since many of
these conditions can happen any time VFs are enabled or disabled and
are not really indicative a fatal problems, unless they happen
continuously.
Shannon disables the link polling to lessen the admin queue traffic
especially since the link event mask usage has been fixed recently.
Alex Duyck fixes the i40e and i40evf drivers to correctly update
checksums for frames up to 16776960 in length which should be more than
large enough for all possible TSO frames in the near future.

====================
vxlan: implement Generic Protocol Extension (GPE)
v3: just rebased on top of the current net-next, no changes
This patchset implements VXLAN-GPE. It follows the same model as the tun/tap
driver: depending on the chosen mode, the vxlan interface is created either
as ARPHRD_ETHER (non-GPE) or ARPHRD_NONE (GPE).
Note that the internal fdb control plane cannot be used together with
VXLAN-GPE and attempt to configure it will be rejected by the driver. In
fact, COLLECT_METADATA is required to be set for now. This can be relaxed in
the future by adding support for static PtP configuration; it will be
backward compatible and won't affect existing users.
The previous version of the patchset supported two GPE modes, L2 and L3. The
L2 mode (now called "ether mode" in the code) was removed from this version.
It can be easily added later if there's demand. The L3 mode is now called
"raw mode" and supports also encapsulated Ethernet headers (via ETH_P_TEB).
The only limitation of not having "ether mode" for GPE is for ip route based
encapsulation: with such setup, only IP packets can be encapsulated. Meaning
no Ethernet encapsulation. It seems there's not much use for this, though.
If it turns out to be useful, we'll add it.

vxlan: implement GPE
Implement VXLAN-GPE. Only COLLECT_METADATA is supported for now (it is
possible to support static configuration, too, if there is demand for it).
The GPE header parsing has to be moved before iptunnel_pull_header, as we
need to know the protocol.
v2: Removed what was called "L2 mode" in v1 of the patchset. Only "L3 mode"
(now called "raw mode") is added by this patch. This mode does not allow
Ethernet header to be encapsulated in VXLAN-GPE when using ip route to
specify the encapsulation, IP header is encapsulated instead. The patch
does support Ethernet to be encapsulated, though, using ETH_P_TEB in
skb->protocol. This will be utilized by other COLLECT_METADATA users
(openvswitch in particular).
If there is ever demand for Ethernet encapsulation with VXLAN-GPE using
ip route, it's easy to add a new flag switching the interface to
"Ethernet mode" (called "L2 mode" in v1 of this patchset). For now,
leave this out, it seems we don't need it.
Disallowed more flag combinations, especially RCO with GPE.
Added comment explaining that GBP and GPE cannot be set together.

igb: Add support for bulk Tx cleanup & cleanup boolean logic
This patch enables bulk free in Tx cleanup for igb and cleans up the
boolean logic in the polling routines for igb in the hopes of avoiding
any mix-ups similar to what occurred with i40e and i40evf.

igb: Fix sparse warning about passing __beXX into leXX_to_cpup
We were casting the addr as __beXX and then passing it into le32_to_cpu
because the device expects the MAC address to be in network order even
though the register set is little endian. Instead of casting it as __beXX
we can just cast it as __leXX in order to maintain consistency since the
region of memory is already in little endian order as far as we are
concerned.

mwifiex: advertise low priority scan feature
Low priority scan handling code which delays or aborts scan
operation based on Tx traffic is removed recently. The reason
is firmware already takes care of it in our new feature scan
channel gap. Hence we should advertise low priority scan
support to cfg80211.
This patch fixes a problem in which OBSS scan request from
wpa_supplicant was being rejected by cfg80211.

rt2x00usb: Use usb anchor to manage URB
With current driver, it is observed that a URB is not
completed while the USB disconnect is initiated. Due to
that, the URB completion handler is trying to access
the resource which was freed as a part of USB disconnect.
Managing the URBs with anchor will make sure that all
the URBs are handled gracefully before device gets

rtlwifi: rtl8723be: Add antenna select module parameter
A number of new laptops have been delivered with only a single antenna.
In principle, this is OK; however, a problem arises when the on-board
EEPROM is programmed to use the other antenna connection. The option
of opening the computer and moving the connector is not always possible
as it will void the warranty in some cases. In addition, this solution
breaks the Windows driver when the box dual boots Linux and Windows.
A fix involving a new module parameter has been developed. This commit
adds the new parameter and implements the changes needed for the driver.

mac80211: add fast-rx path
The regular RX path has a lot of code, but with a few
assumptions on the hardware it's possible to reduce the
amount of code significantly. Currently the assumptions
on the driver are the following:
* hardware/driver reordering buffer (if supporting aggregation)
* hardware/driver decryption & PN checking (if using encryption)
* hardware/driver did de-duplication
* hardware/driver did A-MSDU deaggregation
* AP_LINK_PS is used (in AP mode)
* no client powersave handling in mac80211 (in client mode)
of which some are actually checked per packet:
* de-duplication
* PN checking
* decryption
and additionally packets must
* not be A-MSDU (have been deaggregated by driver/device)
* be data packets
* not be fragmented
* be unicast
* have RFC 1042 header
Additionally dynamically we assume:
* no encryption or CCMP/GCMP, TKIP/WEP/other not allowed
* station must be authorized
* 4-addr format not enabled
Some data needed for the RX path is cached in a new per-station
"fast_rx" structure, so that we only need to look at this and
the packet, no other memory when processing packets on the fast
RX path.
After doing the above per-packet checks, the data path collapses
down to a pretty simple conversion function taking advantage of
the data cached in the small fast_rx struct.
This should speed up the RX processing, and will make it easier
to reason about parallelizing RX (for which statistics will need
to be per-CPU still.)

mac80211: fix last RX rate data consistency
When storing the last_rate_* values in the RX code, there's nothing
to guarantee consistency, so a concurrent reader could see, e.g.
last_rate_idx on the new value, but last_rate_flag still on the old,
getting completely bogus values in the end.
To fix this, I lifted the sta_stats_encode_rate() function from my
old rate statistics code, which encodes the entire rate data into a
single 16-bit value, avoiding the consistency issue.

mac80211: count MSDUs in A-MSDU properly
For the RX MSDU statistics, we need to count the number of
MSDUs created and accepted from an A-MSDU. Right now, all
frames in any A-MSDUs were completely ignored. Fix this by
moving the RX MSDU statistics accounting into the deliver

i40e/i40evf: Fix TSO checksum pseudo-header adjustment
With IPv4 and IPv6 now using the same format for checksums based on the
length of the frame we need to update the i40e and i40evf drivers so that
they correctly account for lengths greater than or equal to 64K.
With this patch the driver should now correctly update checksums for frames
up to 16776960 in length which should be more than large enough for all
possible TSO frames in the near future.

net/core/dev: Warn on a too-short GRO frame
When signaling that a GRO frame is ready to be processed, the network stack
correctly checks length and aborts processing when a frame is less than 14
bytes. However, such a condition is really indicative of a broken driver,
and should be loudly signaled, rather than silently dropped as the case is
today.
Convert the condition to use net_warn_ratelimited() to ensure the stack
loudly complains about such broken drivers.

Allow the VNIC driver to provide descriptors containing

A new function is included for the hypervisor call,
H_SEND_SUBCRQ_INDIRECT, allowing a DMA-mapped array of SCRQ
descriptor elements to be sent to the VNIC server.
These additions will help fully enable checksum offloading as

net: bcmgenet: cleanup for dmadesc_set()
dmadesc_set() is used for setting the Tx buffer DMA address, length,
and status bits on a Tx ring descriptor when a frame is being Tx'ed.
Always set the Tx buffer DMA address first, before updating the length
and status bits, i.e. giving the Tx descriptor to the hardware.
The reason this is a cleanup rather than a fix is that the hardware
won't transmit anything from a Tx ring until the TDMA producer index
has been incremented. As long as the dmadesc_set() writes complete
before the TDMA producer index write, life is good.

udp: enable MSG_PEEK at non-zero offset
Enable peeking at UDP datagrams at the offset specified with socket
option SOL_SOCKET/SO_PEEK_OFF. Peek at any datagram in the queue, up
to the end of the given datagram.
Implement the SO_PEEK_OFF semantics introduced in commit ef64a54f6e55
("sock: Introduce the SO_PEEK_OFF sock option"). Increase the offset
on peek, decrease it on regular reads.
When peeking, always checksum the packet immediately, to avoid
recomputation on subsequent peeks and final read.
The socket lock is not held for the duration of udp_recvmsg, so
peek and read operations can run concurrently. Only the last store
to sk_peek_off is preserved.

====================
40GbE Intel Wired LAN Driver Updates 2016-04-05
This series contains updates to i40e and i40evf only.
Stefan converts dev_close() to ndo_stop() for ethtool offline self test,
since dev_close() causes IFF_UP to be cleared which will remove the
interface routes and addresses.
Alex bumps up the size of the transmit data buffer to 12K rather than 8K,
which provides a gain in throughput and a reduction in overhead for
putting together the frame. Fixed an issue in the polling routines where
we were using bitwise operators to avoid the side effects of the
logical operators. Then added support for bulk transmit clean for skbs.
Jesse fixed a sparse issue in the type casting in the transmit code and
fixed i40e_aq_set_phy_debug() to use i40e_status as a return code.
Catherine cleans up duplicated code.
Shannon fixed the cleaning up of the interrupt handling to clean up the
IRQs only if we actually got them set up. Also fixed up the error
scenarios where we were trying to remove a non-existent timer or
worktask, which causes the kernel heartburn.
Mitch changes the notification of resets to the reset interrupt handler,
instead of the actual reset initiation code. This allows the VFs to get
properly notified for all resets, including resets initiated by different
PFs on the same physical device. Also moved the clearing of VFLR bit
after reset processing, instead of before which could lead to double
resets on VF init. Fixed code comment to match the actual function name.

bnxt_en: Set async event bits when registering with the firmware.
Currently, the driver only sets bit 0 of the async_event_fwd fields.
To be compatible with the latest spec, we need to set the
appropriate event bits handled by the driver. We should be handling
link change and PF driver unload events, so these 2 bits should be
set.

1. Add bnxt_hwrm_set_eee() function to setup EEE firmware parameters based
on the bp->eee settings.
2. The new function bnxt_eee_config_ok() will check if EEE parameters need
to be modified due to autoneg changes.
3. bnxt_hwrm_set_link() has added a new parameter to update EEE. If the
parameter is set, it will call bnxt_hwrm_set_eee().

Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
100GbE Intel Wired LAN Driver Updates 2016-04-05
This series contains updates to fm10k only.
Bruce provides nearly half of the patches in the series, most of which do
general cleanup of the driver. These include semantic cleanups,
checkpatch.pl fixes, update driver to use BIT() kernel macro, use
BUILD_BUG_ON() where appropriate and use ether_addr_copy() instead of
memcpy().
Jake provides the remaining patches in the series, starting with a fix
for a possible NULL pointer deference. Next delays initialization of the
service timer and service task until late in probe(). If we do not wait,
failures in probe do not properly cleanup the service timer or service
task items which result in a kernel panic. Added better reporting during
error conditions. Fixed another possible kernel panic where we were
clearing the interrupt scheme before we freed the mailbox IRQ. Added
helper functions for setting strings and data for ethtool stats. Fixed
comment mis-spelled words.
v2: Dropped patch 3 from the original submission, until a better solution
can be worked up based on feedback from Joe Perches and David Miller.

fm10k: use ethtool_rxfh_indir_default for default redirection table
The fm10k driver used its own code for generating a default indirection
table on device load, which was not the same as the default generated by
ethtool when indir_size of 0 is passed to SRXFH. Take advantage of
ethtool_rxfh_indir_default() and simplify code to write the redirection
table to reduce some code duplication.

Fix a kernel panic that occurs during surprise removal. Clear the

fm10k: free MBX IRQ before clearing interrupt scheme
During fm10k_io_error_detected we were clearing the interrupt scheme
before we freed the MBX IRQ. This causes a kernel panic because the MBX
IRQ are assigned after MSI-X initialization. Clearing the interrupt
scheme results in removing the MSI-X entry table. Fix this by freeing
the MBX IRQ before we clear the interrupt scheme, as we do elsewhere in
the driver.

fm10k: don't initialize service task until later in probe
Delay initialization of the service timer and service task until late
probe. If we don't wait, failures in probe do not properly cleanup the
service timer or service task items, which results in the kernel panic
below, potentially freezing the whole system. In addition, ensure that
the SERVICE_DISABLE bit is set before we request the MBX IRQ since the
MBX interrupt attempts to schedule the service task otherwise. This
prevents a similar trace from occurring after this change.
We didn't notice this issue before because probe almost always completes
successfully. I discovered it due to a mis-ordered mailbox handler
array, which resulted in the following failure when requesting mailbox
interrupt.

fm10k: prevent null pointer dereference of msix_entries table
According to the C standard dereferencing a variable before it is
checked invokes undefined behavior, and thus compilers are free to
assume the check for NULL isn't necessary. Prevent this by re-ordering
the NULL check of msix_entries in fm10k_free_mbx_irq.

mac80211: mesh: flush paths outside of plink lock
Lockdep warned of a lock dependency between the mesh_plink lock
and the internal lock for the rhashtable. The problem is that
the rhashtable code uses a spin lock with softirqs enabled, while
mesh_plink_timer executes a walk (to flush paths on a state change)
inside a softirq with the plink lock held.
This leads to the following deadlock if the timer fires while rht
lock is held on this CPU, and plink lock is held on another CPU:
CPU0 CPU1
---- ----
lock(&(&ht->lock)->rlock);
local_irq_disable();
lock(&(&sta->mesh->plink_lock)->rlock);
lock(&(&ht->lock)->rlock);
<Interrupt>
lock(&(&sta->mesh->plink_lock)->rlock);
*** DEADLOCK ***
Fix by waiting until we drop the plink lock to flush paths.

mac80211: mesh: fix cleanup for mesh pathtable
The mesh path table needs to be around for the entire time the
interface is in mesh mode, as users can perform an mpath dump
at any time. The existing path table lifetime is instead tied
to the mesh BSS which can cause crashes when different MBSSes
are joined in the context of a single interface, or when the
path table is dumped when no MBSS is joined.
Introduce a new function to perform the final teardown of the
interface and perform path table cleanup there. We already
free the individual path elements when the leaving the mesh
so no additional cleanup is needed there. This fixes the
following crash:

The RMC cache has 256 list heads plus a u32, which puts it at the
unfortunate size of 4104 bytes with padding. kmalloc() will then
round this up to the next power-of-two, so we wind up actually
using two pages here where most of the second is wasted.
Switch to hlist heads here to reduce the structure size down to
fit within a page.

mac80211: mesh: handle failed alloc for rmc cache
In the unlikely case that mesh_rmc_init() fails with -ENOMEM,
the rmc pointer will be left as NULL but the interface is still
operational because ieee80211_mesh_init_sdata() is not allowed
to fail.
If this happens, we would blindly dereference rmc when checking
whether a multicast frame is in the cache. Instead just drop the
frames in the forwarding path.

The mesh_path_reclaim() function, called from an rcu callback, cancels
the mesh_path_timer associated with a mesh path. Unfortunately, this

destroyed.
Such a situation led to the following crash in mesh_path_send_to_gates()

Instead of cancelling in the RCU callback, set a new flag to prevent the

cfg80211: allow userspace to specify client P2P PS support
Legacy clients don't support P2P power save mechanisms, and thus
if a P2P GO has a legacy client connected to it, it has to make
some changes in the PS behavior.
To handle this, add an attribute to specify whether a station supports
P2P PS or not. If the attribute was not specified cfg80211 will assume
that station supports it for P2P GO interface, and does NOT support it
for AP interface, matching the current assumptions in the code.

i40evf: Add additional check for reset
If the driver happens to read a register during the time in which the
device is undergoing reset, it will receive a value of 0xdeadbeef
instead of a valid value. Unfortunately, the driver may misinterpret
this as a valid value, especially if it's just looking for individual
bits.
Add an explicit check for this value when we are looking for admin queue
errors, and trigger reset recovery if we find it.

mlxsw: spectrum: Reduce number of supported 802.1D bridges
Resources allocated for these bridges at init time cannot be later used
for other purposes. While current number is supported by the device,
it's mostly theoretical with regards to any real use case, which leads
to poor utilization of device's resources. Solve that by reducing the
number.
The long term plan is to make this value (along with others) user
configurable via devlink and write it to NVRAM, so that it can be used
during the next init. Until then we must hardcode such values.

mac80211: minstrel_ht: improve sample rate skip logic
There were a few issues that were slowing down the process of finding
the optimal rate, especially on devices with multi-rate retry
limitations:
When max_tp_rate[0] was slower than max_tp_rate[1], the code did not
sample max_tp_rate[1], which would often allow it to switch places with
max_tp_rate[0] (e.g. if only the first sampling attempts were bad, but the
rate is otherwise good).
Also, sample attempts of rates between max_tp_rate[0] and [1] were being
ignored in this case, because the code only checked if the rate was
slower than [1].
Fix this by checking against the fastest / second fastest max_tp_rate
instead of assuming a specific order between the two.
In my tests this patch significantly reduces the time until minstrel_ht
finds the optimal rate right after assoc

i40e/i40evf: Add support for bulk free in Tx cleanup
This patch enables bulk Tx clean for skbs. In order to enable it we need
to pass the napi_budget value as that is used to determine if we are truly
running in NAPI mode or if we are simply calling the routine from netpoll
with a budget of 0. In order to avoid adding too many more variables I
thought it best to pass the VSI directly in a fashion similar to what we do
on igb and ixgbe with the q_vector.

mac80211: synchronize driver rx queues before removing a station
Some devices, like iwlwifi, have RSS queues. This may cause a
situation where a disassociation is handled in control path and
results in station removal while there are prior RX frames
that were still not processed in other queues. When they will
be processed the station will be gone, and the frames will be
dropped.

mac80211: mesh: embed known gates list in struct mesh_path
The mesh path table uses a struct mesh_node in its hlists in
order to support a resizable hash table: the mesh_node provides
an indirection to the actual mesh path so that two different
bucket lists can point to the same path entry.
However, for the known gates list, we don't need this indirection
because there is ever only one list. So we can just embed the
hlist_node in the mesh path itself, which simplifies things a bit
and saves a linear search whenever we need to find an item in
the list.

This allows scans for a specific BSSID to be optimized by the user space
application by requesting the driver to set the Probe Request frame
BSSID field (Address 3) to the specified BSSID instead of the wildcard
BSSID. This prevents other APs from replying which reduces airtime need
and latency in getting the response from the target AP through.
This is an optimization and as such, it is acceptable for some of the
drivers not to support the mechanism. If not supported, the wildcard
BSSID will be used and more responses may be received.

instead replaces the entire thing with just an if statement since it should

i40e/i40evf: Allow up to 12K bytes of data per Tx descriptor instead of 8K
From what I can tell the practical limitation on the size of the Tx data
buffer is the fact that the Tx descriptor is limited to 14 bits. As such
we cannot use 16K as is typically used on the other Intel drivers. However
artificially limiting ourselves to 8K can be expensive as this means that
we will consume up to 10 descriptors (1 context, 1 for header, and 9 for
payload, non-8K aligned) in a single send.
I propose that we can reduce this by increasing the maximum data for a 4K
aligned block to 12K. We can reduce the descriptors used for a 32K aligned
block by 1 by increasing the size like this. In addition we still have the
4K - 1 of space that is still unused. We can use this as a bit of extra
padding when dealing with data that is not aligned to 4K.
By aligning the descriptors after the first to 4K we can improve the
efficiency of PCIe accesses as we can avoid using byte enables and can fetch
full TLP transactions after the first fetch of the buffer. This helps to
improve PCIe efficiency. Below is the results of testing before and after
with this patch:
Recv Send Send Utilization Service Demand
Socket Socket Message Elapsed Send Recv Send Recv
Size Size Size Time Throughput local remote local remote
bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB
Before:
87380 16384 16384 10.00 33682.24 20.27 -1.00 0.592 -1.00
After:
87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -1.00
So the net result of this patch is that we have a small gain in throughput
due to a reduction in overhead for putting together the frame.

====================
net: various udp/tcp changes
First round of patches for linux-4.7
Add a generic facility for sockets to be freed after an RCU grace
period, if they need to.
Then UDP stack is changed to no longer use SLAB_DESTROY_BY_RCU,
in order to speedup rx processing for traffic encapsulated in UDP.
It gives a 17 % speedup for normal UDP reception in stress conditions.
Then TCP listeners are changed to use SOCK_RCU_FREE as well
to avoid touching sk_refcnt in synflood case :
I got up to 30 % performance increase for a mono listener.
Then three patches add SK_MEMINFO_DROPS to sock_diag
and add per socket rx drops accounting to TCP.
Last patch adds rate limiting on ACK sent on behalf of SYN_RECV
to better resist to SYNFLOOD targeting one or few flows.

tcp: rate limit ACK sent by SYN_RECV request sockets
Attackers like to use SYNFLOOD targeting one 5-tuple, as they
hit a single RX queue (and cpu) on the victim.
If they use random sequence numbers in their SYN, we detect
they do not match the expected window and send back an ACK.
This patch adds a rate limitation, so that the effect of such
attacks is limited to ingress only.
We roughly double our ability to absorb such attacks.

ipv4: tcp: set SOCK_USE_WRITE_QUEUE for ip_send_unicast_reply()
TCP uses per cpu 'sockets' to send some packets :
- RST packets ( tcp_v4_send_reset()) )
- ACK packets for SYN_RECV and TIMEWAIT sockets
By setting SOCK_USE_WRITE_QUEUE flag, we tell sock_wfree()
to not call sk_write_space() since these internal sockets
do not care.
This gives a small performance improvement, merely by allowing
cpu to properly predict the sock_wfree() conditional branch,
and avoiding one atomic operation.

tcp/dccp: do not touch listener sk_refcnt under synflood
When a SYNFLOOD targets a non SO_REUSEPORT listener, multiple
cpus contend on sk->sk_refcnt and sk->sk_wmem_alloc changes.
By letting listeners use SOCK_RCU_FREE infrastructure,
we can relax TCP_LISTEN lookup rules and avoid touching sk_refcnt
Note that we still use SLAB_DESTROY_BY_RCU rules for other sockets,

Peak performance under SYNFLOOD is increased by ~33% :
On my test machine, I could process 3.2 Mpps instead of 2.4 Mpps
Most consuming functions are now skb_set_owner_w() and sock_wfree()

RX packet processing holds rcu_read_lock(), so we can remove
pairs of rcu_read_lock()/rcu_read_unlock() in lookup functions
if inet_diag also holds rcu before calling them.
This is needed anyway as __inet_lookup_listener() and

udp: no longer use SLAB_DESTROY_BY_RCU
Tom Herbert would like not touching UDP socket refcnt for encapsulated
traffic. For this to happen, we need to use normal RCU rules, with a grace
period before freeing a socket. UDP sockets are not short lived in the
high usage case, so the added cost of call_rcu() should not be a concern.
This actually removes a lot of complexity in UDP stack.
Multicast receives no longer need to hold a bucket spinlock.
Note that ip early demux still needs to take a reference on the socket.
Same remark for functions used by xt_socket and xt_PROXY netfilter modules,
but this might be changed later.
Performance for a single UDP socket receiving flood traffic from
many RX queues/cpus.
Simple udp_rx using simple recvfrom() loop :
438 kpps instead of 374 kpps : 17 % increase of the peak rate.
v2: Addressed Willem de Bruijn feedback in multicast handling
- keep early demux break in __udp4_lib_demux_lookup()

net: add SOCK_RCU_FREE socket flag
We want a generic way to insert an RCU grace period before socket
freeing for cases where RCU_SLAB_DESTROY_BY_RCU is adding too
much overhead.
SLAB_DESTROY_BY_RCU strict rules force us to take a reference
on the socket sk_refcnt, and it is a performance problem for UDP
encapsulation, or TCP synflood behavior, as many CPUs might
attempt the atomic operations on a shared sk_refcnt
UDP sockets and TCP listeners can set SOCK_RCU_FREE so that their
lookup can use traditional RCU rules, without refcount changes.
They can set the flag only once hashed and visible by other cpus.

====================
10GbE Intel Wired LAN Driver Updates 2016-04-04
This series contains updates to ixgbe and ixgbevf.
Pavel Tikhomirov fixes a typo where we were incrementing transmit stats
instead of receive stats on the receive side.
Emil updates the ixgbevf driver to use bit operations for setting and
checking the adapter state.
Chas Williams adds the new NDO trust feature check so that the VF guest
has the ability to set the unicast address of the interface, if it is a
trusted VF.
Alex cleans up the driver to that the only time we add a PF entry to the
VLVF is either for VLAN 0 or if the PF has requested a VLAN that a VF
is already using. Also adds support for generic transmit checksums,
giving the added advantage is that we can support inner checksum offloads
for tunnels and MPLS while still being able to transparently insert
VLAN tags. Lastly, changed ixgbe so that we can use the ethtool
rx-vlan-filter flag to toggle receive VLAN filtering on and off.
Mark cleans up the ixgbe driver by making all op structures that do not
change constants. Also fixed flow control for Xeon D KR backplanes, since
we cannot use auto-negotiation to determine the mode, we have to use
whatever the user configured.
Sowmini Varadhan updates ixgbe to use eth_platform_get_mac_address()
instead of the arch specific solution that was added by a previous
commit.
Don fixed an issue where it was possible that a system reset could occur
when we were holding the SWFW semaphore lock, which the next time the
driver loaded would see it incorrectly as locked.
v2: updated patch 8 of the series to include a minor flags issue where
we had lost NETIF_F_HW_TC and we were setting NETIF_F_SCTP_CRC in
two different areas, when we only needed/wanted it in one spot.

====================
net: dsa: mv88e6131: HW bridging support for 6185
All packets passing through a switch of the 6185 family are currently all
directed to the CPU port. This means that port bridging is software driven.
To enable hardware bridging for this switch family, we need to implement the
port mapping operations, the FDB operations, and optionally the VLAN operations
(for 802.1Q and VLAN filtering aware systems).
However this family only has 256 FDBs indexed by 8-bit identifiers, opposed to
4096 FDBs with 12-bit identifiers for other families such as 6352. It also
doesn't have dedicated FID registers for ATU and VTU operations.
This patchset fixes these differences, and enable hardware bridging for 6185.
Changes v1 -> v2:
- Describe the different numbers of databases and prefer a feature-based logic
over the current ID/family-based logic.

ixgbevf: Add support for generic Tx checksums
This patch adds support for generic Tx checksums to the ixgbevf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

ravb: Add dma queue interrupt support
This patch supports the following interrupts.
- One interrupt for multiple (timestamp, error, gPTP)
- One interrupt for emac
- Four interrupts for dma queue (best effort rx/tx, network control rx/tx)
This patch improve efficiency of the interrupt handler by adding the
interrupt handler corresponding to each interrupt source described
above. Additionally, it reduces the number of times of the access to
EthernetAVB IF.
Also this patch prevent this driver depends on the whim of a boot loader.

Merge branch 'cmsg_timestamp'
Soheil Hassas Yeganeh says:
====================
add TX timestamping via cmsg
This patch series aim at enabling TX timestamping via cmsg.
Currently, to occasionally sample TX timestamping on a socket,
applications need to call setsockopt twice: first for enabling
timestamps and then for disabling them. This is an unnecessary
overhead. With cmsg, in contrast, applications can sample TX
timestamps per sendmsg().
This patch series adds the code for processing SO_TIMESTAMPING
for cmsg's of the SOL_SOCKET level, and adds the glue code for
TCP, UDP, and RAW for both IPv4 and IPv6. This implementation
supports overriding timestamp generation flags (i.e.,
SOF_TIMESTAMPING_TX_*) but not timestamp reporting flags.
Applications must still enable timestamp reporting via
setsockopt to receive timestamps.
This series does not change existing timestamping behavior for
applications that are using socket options.
I will follow up with another patch to enable timestamping for
active TFO (client-side TCP Fast Open) and also setting packet
mark via cmsgs.
Thanks!
Changes in v2:
- Replace u32 with __u32 in the documentation.
Changes in v3:
- Fix the broken build for L2TP (due to changes
in IPv6).

sock: enable timestamping using control messages
Currently, SOL_TIMESTAMPING can only be enabled using setsockopt.
This is very costly when users want to sample writes to gather
tx timestamps.
Add support for enabling SO_TIMESTAMPING via control messages by
using tsflags added in `struct sockcm_cookie` (added in the previous
patches in this series) to set the tx_flags of the last skb created in
a sendmsg. With this patch, the timestamp recording bits in tx_flags
of the skbuff is overridden if SO_TIMESTAMPING is passed in a cmsg.
Please note that this is only effective for overriding the recording
timestamps flags. Users should enable timestamp reporting (e.g.,
SOF_TIMESTAMPING_SOFTWARE | SOF_TIMESTAMPING_OPT_ID) using
socket options and then should ask for SOF_TIMESTAMPING_TX_*
using control messages per sendmsg to sample timestamps for each
write.

ipv6: process socket-level control messages in IPv6

__sock_cmsg_send in ip6_datagram_send_ctl for control messages on
the SOL_SOCKET layer.
This makes sure whenever ip6_datagram_send_ctl is called for
udp and raw, we also process socket-level control messages.
This is a bit uglier than IPv4, since IPv6 does not have
something like ipcm_cookie. Perhaps we can later create
a control message cookie for IPv6?
Note that this commit interprets new control messages that
were ignored before. As such, this commit does not change

sock: accept SO_TIMESTAMPING flags in socket cmsg
Accept SO_TIMESTAMPING in control messages of the SOL_SOCKET level
as a basis to accept timestamping requests per write.
This implementation only accepts TX recording flags (i.e.,
SOF_TIMESTAMPING_TX_HARDWARE, SOF_TIMESTAMPING_TX_SOFTWARE,
SOF_TIMESTAMPING_TX_SCHED, and SOF_TIMESTAMPING_TX_ACK) in
control messages. Users need to set reporting flags (e.g.,
SOF_TIMESTAMPING_OPT_ID) per socket via socket options.
This commit adds a tsflags field in sockcm_cookie which is
set in __sock_cmsg_send. It only override the SOF_TIMESTAMPING_TX_*
bits in sockcm_cookie.tsflags allowing the control message
to override the recording behavior per write, yet maintaining
the value of other flags.
This patch implements validating the control message and setting
tsflags in struct sockcm_cookie. Next commits in this series will
actually implement timestamping per write for different protocols.

tcp: use one bit in TCP_SKB_CB to mark ACK timestamps
Currently, to avoid a cache line miss for accessing skb_shinfo,
tcp_ack_tstamp skips socket that do not have
SOF_TIMESTAMPING_TX_ACK bit set in sk_tsflags. This is
implemented based on an implicit assumption that the
SOF_TIMESTAMPING_TX_ACK is set via socket options for the
duration that ACK timestamps are needed.
To implement per-write timestamps, this check should be
removed and replaced with a per-packet alternative that
quickly skips packets missing ACK timestamps marks without
a cache-line miss.
To enable per-packet marking without a cache line miss, use
one bit in TCP_SKB_CB to mark a whether a SKB might need a
ack tx timestamp or not. Further checks in tcp_ack_tstamp are not
modified and work as before.

tcp: accept SOF_TIMESTAMPING_OPT_ID for passive TFO
SOF_TIMESTAMPING_OPT_ID is set to get data-independent IDs
to associate timestamps with send calls. For TCP connections,
tp->snd_una is used as the starting point to calculate
relative IDs.
This socket option will fail if set before the handshake on a
passive TCP fast open connection with data in SYN or SYN/ACK,
since setsockopt requires the connection to be in the
ESTABLISHED state.
To address these, instead of limiting the option to the
ESTABLISHED state, accept the SOF_TIMESTAMPING_OPT_ID option as
long as the connection is not in LISTEN or CLOSE states.

This causes a double walk on the cmsghdr list, one for SOL_SOCKET

ath10k: reuse copy engine 5 (htt rx) descriptors
Whenever htt rx indication i.e target to host messages are received
on rx copy engine (CE5), the message will be freed after processing
the response. Then CE 5 will be refilled with new descriptors at
post rx processing. This memory alloc and free operations can be avoided
by reusing the same descriptors.
During CE pipe allocation, full ring is not initialized i.e n-1 entries
are filled up. So for CE 5 full ring should be filled up to reuse
descriptors. Moreover CE 5 write index will be updated in single shot
instead of incremental access. This could avoid multiple pci_write and
ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019
platform.

refilling it for htt rx copy engine (CE5). To support that all htt rx
indications should be proecssed at same context. Instead of queueing
actual indication message, queue copied message for txrx processing.

Merge branch 'stmmac-GMAC4.x'
Alexandre TORGUE says:
====================
Enhance stmmac driver to support GMAC4.x IP
This is a subset of patch to enhance current stmmac driver to support
new GMAC4.x chips. New set of callbacks is defined to support this new
family: descriptors, dma, core.
One of main changes of GMAC 4.xx IP is descriptors management.
-descriptors are only used in ring mode.
-A descriptor is composed of 4 32bits registers (no more extended
descriptors)
-descriptor mechanism (Tx for example, but it is exactly the same for RX):
-useful registers:
-DMA_CH#_TxDesc_Ring_Len: length of transmit descriptor ring
-DMA_CH#_TxDesc_List_Address: start address of the ring
-DMA_CH#_TxDesc_Tail_Pointer: address of the last descriptor to send + 1.
-DMA_CH#_TxDesc_Current_App_TxDesc: address of the current descriptor
-The descriptor Tail Pointer register contains the pointer to the
descriptor address (N). The base address and the current
descriptor decide the address of the current descriptor that the
DMA can process. The descriptors up to one location less than the
one indicated by the descriptor tail pointer (N-1) are owned by
the DMA. The DMA continues to process the descriptors until the
following condition occurs:
"current descriptor pointer == Descriptor Tail pointer"
Then the DMA goes into suspend mode. The application must perform
a write to descriptor tail pointer register and update the tail
pointer to have the following condition and to start a new transfer:
"current descriptor pointer < Descriptor tail pointer"
The DMA automatically wraps around the base address when the end
of ring is reached.
New features are available on IP:
-TSO (TCP Segmentation Offload) for TX only
-Split header: to have header and payload in 2 different buffers (not yet implemented)
Below some throughput figures obtained on some boxes:
iperf (mbps)
--------------------------------------
tcp udp
tx rx tx rx
-----------------
GMAC4.x 935 930 750 800
Note: There is a change in 4.10a databook on bitfield mapping of DMA_CHANx_INTR_ENA register.
This requires to have é diffrent set of callbacks between IP 4.00a and 4.10a.

tcp: remove cwnd moderation after recovery
For non-SACK connections, cwnd is lowered to inflight plus 3 packets
when the recovery ends. This is an optional feature in the NewReno
RFC 2582 to reduce the potential burst when cwnd is "re-opened"
after recovery and inflight is low.
This feature is questionably effective because of PRR: when
the recovery ends (i.e., snd_una == high_seq) NewReno holds the
CA_Recovery state for another round trip to prevent false fast
retransmits. But if the inflight is low, PRR will overwrite the
moderated cwnd in tcp_cwnd_reduction() later regardlessly. So if a
receiver responds bogus ACKs (i.e., acking future data) to speed up
transfer after recovery, it can only induce a burst up to a window
worth of data packets by acking up to SND.NXT. A restart from (short)
idle or receiving streched ACKs can both cause such bursts as well.
On the other hand, if the recovery ends because the sender
detects the losses were spurious (e.g., reordering). This feature
unconditionally lowers a reverted cwnd even though nothing
was lost.
By principle loss recovery module should not update cwnd. Further
pacing is much more effective to reduce burst. Hence this patch
removes the cwnd moderation feature.
v2 changes: revised commit message on bogus ACKs and burst, and
missing signature

iwlwifi: mvm: support bss dynamic alloc/dealloc of queues
"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.
Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.
There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.
This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.
When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.
When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

iwlwifi: pcie: do not pad QoS AMSDU
We insert padding if the MAC header's size is not a multiple of 4
to ensure that the SNAP header is DWORD aligned. When we do so, we
let the firmware know by setting a bit in Tx command
(TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those
2 bytes before sending the frame.
However, this is not needed for AMSDU as the sub frame header (14B)
complements the MAC header (26B) so that the SNAP header is DWORD
aligned without adding any pad.
Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit
but rather checked the length of the MAC header itself and
assumed the entity that enqueued the frame (driver or internal
firmware code) added the pad.
Since the driver inserted the pad even for AMSDU this logic applied.
Note that the padding is a DMA optimization but it's not strictly
needed, so we could pad even if it was not needed.
However, the CSUM hardware introduced for the 9000 devices requires
to not pad AMSDU as it is not needed, and will fail if such a pad
exists.
Due to older FW not checking the padding bit but checking the mac
header size itself - we cannot do this adjustments for older
generations.
Do not align the size if it is an AMSDU and HW checksum is enabled -
which will only happen on 9000 devices and on.

iwlwifi: pcie: enable interrupts explicitly on resume
When entering suspend the driver calls iwl_disable_interrupts() and
then iwl_pcie_disable_ict().
On resume the driver calls only iwl_pcie_reset_ict() without calling
explicitly to iwl_enable_interrupts().
This mostly works since iwl_pcie_reset_ict is calling to
iwl_enable_interrupts, but it doesn't work when there is no ict_table
in MSIx mode.
The result is that driver tries to resume but fails since it doesn't
get the RX interrupt from FW indicating that d0i3 exit was completed.
Fix it by adding an explicit call to enable interrupts.

iwlwifi: mvm: add LQM vendor command and notification
LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.
The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

any other info). So, using existing same cal file name and DT entry
in qca4019 case would alter the purpose of it. To avoid this, new cal
file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name
'qcom,ath10k-pre-calibration-data are introduced.
Overall qca4019's firmware download sequence would look like,
1) Download cal data (either from a file or device tree entry)
at the address specified by target in the host interest area
member "hi_board_data".
2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID)
as a argument.
At this point, otp will take back up of downloaded cal data
content in another location in the target and return valid
board id and chip id to the host.
3) Download board data at the address specified by target
in host interest area member "hi_board_data".
4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as
a argument.
Now otp will apply cal data content from it's backup on top
of board data download in step 3 and prepare final data base.
5) Download code swap and athwlan binary content.
Above sequences are implemented (step 1 to step 4) in the name of
pre calibration configuration.

ath10k: move cal data len to hw_params
ath10k_download_cal_dt() compares obtained cal data content length
against QCA988X_CAL_DATA_LEN (2116 bytes). It was written by keeping
qca988x in mind. In fact, cal data length is more chip specific.
To make ath10k_download_cal_dt() more generic and reusable for other
chipsets (like qca4019), cal data length is moved to hw_params.

ath10k: pass cal data location as an argument to ath10k_download_cal_{file|dt}
Both ath10k_download_cal_file() and ath10k_download_cal_dt() uses
hard coded file pointer (ar->cal_file) and device tree entry
(qcom,ath10k-calibration-data) respectively to get calibration
data content.
There is a need to use those two functions in qca4019 calibration
download sequence with different file pointer and device tree entry name.
Modify those two functions to take cal data location as an argument.
So that it can serve the purpose for other file pointer and device
tree entry.
This is just preparation before adding actual qca4019 calibration
download sequence. No functional changes.

dt: bindings: add new dt entry for pre calibration in qcom, ath10k.txt
There two things done in this patch,
1) Existing device tree entry 'qcom,ath10k-calibration-data' carries
not only calibration data, it carries board specific data too.
So, make appropriate update in doc.
2) ipq4019 wifi needs new devie tree entry to carry calibration
data alone (called pre cal data, it doesn't include any other info).
Using 'qcom,ath10k-calibration-data' for ipq4019 would alter
the purpose of it. Hence, add new device tree entry called
'qcom,ath10k-pre-calibration-data' to carry only pre calibration data.

iwlwifi: mvm: make sure FW contains the right amount of paging sections
Paging contains 3 sections in the fw. The first for the paging separator,
The second for the CSS block, the third with the paging data.
Currently if the driver finds the paging separator, and there is only
section left (CSS), once reading the CSS section, the driver will
attempt to read the paging data and will go out of the arrays bounds.
Make sure that the FW image contains the right amount of sections for
paging.

iwlwifi: mvm: Decrease size of the paging download buffer
Currently the driver has 2 buffers for paging:
1. paging db - this contains all of the pages that were in the FW
image, that the driver stores for the FW. This is allocated for each
block separately (not contiguous).
2. download buffer - we need to provide this empty buffer for the
iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
memory. This is one big buffer of contiguous memory whose size is the
size of all the blocks that the fw paging section can contain.
This download buffer size is too big, and causes the allocation to fail
sometimes. Since the driver allocates memory for each block separately,
it is not possible for the FW to request all of the pages in one request
(the FW gives an address and size, so blocks need to be contiguous for
this to happen), therefore the FW is limited to request only one block.
Decrease the size of the paging download buffer to be the size of a
paging block.

ath10k: move mgmt descriptor limit handle under mgmt_tx
Frames that are transmitted via MGMT_TX are using reserved descriptor
slots in firmware. This limitation is for the htt_mgmt_tx path itself,
not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots
will be easy exhausted due to frequent probe responses. So for 10.4
based solutions, probe responses are limited by a threshold (24).
management tx path is separate for all except tlv based solutions. Since
tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is
safe to move management descriptor limitation check under mgmt_tx
function. Though CPU improvement is negligible, unlikely conditions or
never hit conditions in hot path can be avoided on data transmission.

This leads to packet drop due to unknown channel and kernel log will be

ath6kl: ignore WMI_TXE_NOTIFY_EVENTID based on fw capability flags
Certain 6004 firmware releases redefine the WMI_TXE_NOTIFY_EVENTID event
number and sends the new event frequently. However it doesn't have the
tx-err-notify feature and thus this firmware capability flag isn't set on
the firmware package. By guarding the processing of this event by the same
method we guard the sending of the WMI_SET_TXE_NOTIFY_CMDID command, we
can ignore the spurious event that we don't know how to process.
Without this change we call cfg80211_cqm_txe_notify() with possibly bad

commit f49c90db4d23 ("ath9k: Add a macro to identify PCOEM chips")
defined AR_SREV_9003_PCOEM macro, its more clear to use the macro
instead of checking one by one. Also removed PCOEM chips checking
in the callback of ar9003_hw_do_pcoem_manual_peak_cal() which only
for PCOEM chips.

wil6210: fix race conditions in p2p listen and search
Fix 2 race conditions found during test runs of P2P discovery:
1. Because wil_p2p_cancel_listen was not protected, user space
could start a new P2P listen/search before wmi_stop_discovery
completed. This caused a crash in the firmware.
2. In P2P listen, when listen timer expires and user space calls
cancel_remain_on_channel at the same time, code could send the
cfg80211_remain_on_channel_expired notification twice.
Added protections with wil->mutex to several places that call
wmi_stop_discovery.

wil6210: P2P_DEVICE virtual interface support
Added support for the P2P_DEVICE virtual interface. This interface
is intended for P2P management operations such as discovery and
GO negotiation. Normally it is implemented by drivers to allow
a separate interface for P2P management with its own MAC address,
but for 11ad drivers it is needed to support P2P search, since it
cannot otherwise be separated from normal scan.
Since we only support a single interface/MAC address, we can't
easily separate between primary and P2P_DEVICE interfaces.
For example when a management packet arrives we can't tell for
which interface it is intended. To work around this, we store
a pointer to the interface where the last "radio operation" was
triggered such as scan or remain on channel, and we forward
management packets and scan results to this interface.

wil6210: basic PBSS/PCP support
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
For example, stations inside a PBSS can communicate directly, and
the PCP role can be transferred between stations.
This change adds PBSS support, and has 2 main parts:
1. When starting an AP, add an option to start as a PCP instead.
This is implemented by a new PBSS flag which is passed as part of
the cfg80211_ap_settings structure.
2. When connecting to a BSS, add an option to connect to a PCP
instead of an AP. This is again implemented by a new PBSS flag,
added to the cfg80211_connect_params structure.

wil6210: add support for discovery mode during scan
Add support for discovery mode during scan. When discovery mode
is active, station transmits special beacons while scanning.
This can optimize the scan mainly when there is only one AP/PCP
around.
Discovery mode is implicitly used by firmware during P2P search.
Since there is currently no use case where user space has a
reason to directly control discovery mode, we expose it only
through a debugfs flag.
Also fix name confusion in the wmi_scan_type enumeration.
The type previously called WMI_LONG_SCAN is actually
WMI_ACTIVE_SCAN.

wil6210: remove BACK RX and TX workers
WMI synchronous handling has changed and WMI calls that provide
a buffer for the reply are completed in the WMI interrupt context.
This allows sending the RX and TX BACK commands from the WMI event
handler without the need for the worker thread.
This is a better approach as it can decrease the handshake time
in the connect flow and prevent race conditions in case of fast
disconnects. An example for such a race is handling of wil_back_rx_handle
during a disconnect event, as wil_back_rx_handle is not protected by
the wil mutex and a disconnect can be handled after sta->status is
verified as connected.

there's no non-peer-flow-ctrl QCA4019 firmware.
However QCA99X0 is planned to run firmware
supporting the feature as well. Therefore this
patch enables QCA99X0 to use 2500 tx descriptors
whenever possible instead of just 1424.

ath10k: fix HTT Tx CE ring size
QCA4019 can queue up to 2500 frames at a time.
This means it requires roughly 5000 entires on the
ring to work properly. Otherwise random tx failure
may occur.

ath10k: implement push-pull tx
The current/old tx path design was that host, at
its own leisure, pushed tx frames to the device.
For HTT there was ~1000-1400 msdu queue depth.
After reaching that limit the driver would request
mac80211 to stop queues. There was little control
over what packets got in there as far as
DA/RA was considered so it was rather easy to
starve per-station traffic flows.
With MU-MIMO this became a significant problem
because the queue depth was insufficient to buffer
frames from multiple clients (which could have
different signal quality and capabilities) in an
efficient fashion.
Hence the new tx path in 10.4 was introduced: a
pull-push mode.
Firmware and host can share tx queue state via
DMA. The state is logically a 2 dimensional array
addressed via peer_id+tid pair. Each entry is a
counter (either number of bytes or packets. Host
keeps it updated and firmware uses it for
scheduling Tx pull requests to host.
This allows MU-MIMO to become a lot more effective
with 10+ clients.

ath10k: implement updating shared htt txq state
Firmware 10.4.3 onwards can support a pull-push Tx
model where it shares a Tx queue state with the
host.
The host updates the DMA region it pointed to
during HTT setup whenever number of software
queued from (on host) changes. Based on this
information firmware issues fetch requests to the
host telling the host how many frames from a list
of given stations/tids should be submitted to the
firmware.
The code won't be called because not all
appropriate HTT events are processed yet.

ath10k: add fast peer_map lookup
The pull-push functionality of 10.4 will be based
on peer_id and tid. These will need to be mapped,
eventually, to ieee80211_txq to be used with
ieee80211_tx_dequeue().
Iterating over existing stations every time
peer_id needs to be mapped to a station would be
inefficient wrt CPU time.
The new firmware, which will be the only user of
the code flow-wise, will guarantee to use low
peer_ids first so despite peer_map's apparent huge
size d-cache thrashing should not be a problem.
Older firmware hot paths will effectively not use
peer_map.

ath10k: maintain peer_id for each sta and vif
The 10.4.3 firmware with congestion control
guarantees that each peer has only a single

The 1:1 mapping isn't the case for older firmwares
(e.g. 10.4.1, 10.2, 10.1) but it should not
matter. This 1:1 mapping is going to be only used
by future code which inherently (flow-wise) is for
10.4.3.

ath10k: refactor tx pending management
Tx pending counter logic assumed that the sk_buff
is already known and hence was performed in HTT
functions themselves.
However, for the sake of future wake_tx_queue()
usage the driver must be able to tell whether it
can submit more frames to firmware before it
dequeues frame from ieee80211_txq (and thus long
before HTT Tx functions are called) because once a
frame is dequeued it cannot be requeud back to
mac80211.
This prepares the driver for future changes.

batman-adv: Avoid duplicate neigh_node additions
Two parallel calls to batadv_neigh_node_new() might race for creating
and adding the same neig_node. Fix this by including the check for any
already existing, identical neigh_node within the spin-lock.
