[B.A.T.M.A.N.] The state of batman-adv branches in august 2010
by Sven Eckelmann
Hi,
as we started to have different branches and repositories, everything
became a little bit more complex to track. I will try to summarize what
and where is something going on inside the batman-adv universe.
There is currently one main change happening in the branch design. The
branch currently called 'maint' will be renamed to 'next'. This should
reflect that we work there on the features (already part of
master/trunk) which should be submitted to the kernel maintainers. This
branch is stopped quite early in the development phase - even before the
kernel with the corresponding features will be released.
For example the current patches for linux 2.6.36 (which will may be
released in 5 weeks) will be finished with the release of v2010.1.0. The
next branch will get immediately all patches which will be part of linux
2.6.37. This is needed because all patches must be tested in linux-next
a long time before Linus Torvalds opens the merge window vor linux
2.6.37.
Of course, this will create a small gap for bug fixes which will enter
linux 2.6.36 after the release of v2010.1.0. That's why we now use the
maint branch to track those changes. Maint will always be a branch on
top of the last release with all bugfixes which must be added to that
release and are not features for the next branch.
That new maint branch will also help other distributors to easily find
patches which should be applied on top of their shipped versions or for
users which want to build their version of batman-adv manually and still
get a version which fixes (hopefully) all know bugs. And maybe we will
have bug fix releases in the future...
* trunk/batman-adv/ [1], master [2]
In trunk is always summer - so changes always(?) enter here and will
get moved to other branches unless they need some more time to get a
fine flavor - or at least more testing. Even if everything should hit
trunk, it is easier to describe changes in a different places (next,
master-rebase).
This branch can be used together with trunk/batctl/ [3]
* next [4]
This is were commits are gathered to be send later to the linux
kernel folks. Only tested features or features which are dependencies
for the in-kernel batman-adv should enter this branch.
Since the last time [5] many things happened, but not all are
finished yet. So for example the release of v2010.1.0 is still
pending and so no patches for linux-2.6.37 have been send to GregKH.
Meanwhile we had to deal a little bit with some regressions which
were added when we changed to everything from procfs to sysfs. This
is the reason why there were some patches sent to the linux
stable-tree folks lately.
After that release we we will merge some patches which are mostly
needed to push the merge of batman-adv into linux-net a little bit
further. That includes for example the preparation of nearly all data
inside of skbs instead of external buffers and the usage of optimized
kernel functionality for things which we tried to implement our self.
But of course there are again quite interesting features:
* batman-adv: layer2 unicast packet fragmentation
* batman-adv: attach each hard-interface to a soft-interface
* batman-adv: multiple mesh clouds
Also patches were added which tweaked a little bit here and there.
Many of them came directly from the kernel folks and dealt with
smaller coding style problems.
This branch can be used together with batctl-next [6]
* linux-2.6.36
The release of linux 2.6.36 isn't finished yet, but we have submitted
all patches in next. We aren't yet in net/, but hope that this
follows soon. All problems which David S. Miller [7] found were
relative small and already fixed. We will wait until the first
patches for the upcoming merge window were send to the staging tree,
before we try to get really into net/.
You may experienced some weird regressions when using early -RCs of
linux 2.6.36. Those happened due to some smaller patch war between
the guys from linux-net and us. Those changes clashed when GregKH had
to merge them after the release of 2.6.35. Unfortunately he resolved
the merge conflicts a little bit different than I expected. But those
problems should be solved with the upcoming release of linux
2.6.36-rc3.
* linux [8]
The dirty place were all the linux integration happens. It is ugly,
misunderstood and uninteresting for most people.
The last synchronization point was GregKH-20100821 [9]. It is a merge
of linux-2.6.36-rc1 and v2010.0.0-46-ge3a0cc9 [10] + a documentation
of all files we create in sysfs. So this synchronization point (a git
tag) just says that we checked at least linux-2.6.36-rc1 for new
patches not yet integrated in next/trunk of batman-adv and that we
send our changes until that point to GregKH [11].
* rebase [12]
My personal playground. (With a little delay) I will try to get all
changes in trunk rebased on top of next. As result we get only the
essence of changes in trunk which aren't already part of next. This
also means for example that patches will look like they were made
with sysfs in mind when they are originally created files in /proc.
Even when I always ensure that the files in master and rebase are
100% equal, the original author may not be blamed when a single patch
will try to eat your pet (or you could say that patches in that
branch will not be checked by their original authors and I will only
guarantee that when you apply all patches you will get the same files
as in trunk).
Nevertheless it is a great place to get and test feature patches on
top of next without using the complete set of changes in master. Or
to understand what goes on in trunk compared to next.
After the release of v2010.1.0 we will only have the gateway patches
again waiting to get merged into next.
* batman-adv: adapting source version to revised versioning scheme [13]
* batman-adv: adding gateway functionality [14]
* batman-adv: send DHCP requests directly to the chosen gw [15]
* batman-adv: best gw DHCP filter 802.1Q support [16]
This branch will jump around and it is not save to track it using a
local git branch.
It can be used together with trunk/batctl/ [3]
Maybe this is a good place to announce that there is something like
master-rebase also to rebase current patches of batctl [17] on top of
the latest release. It is unknown who will continue the work on that,
but as it is not as complex at the kernel module, I doubt that it is
really much work rebase and reorder those patches.
Last but not least, thanks to everyone who has done the real work
* Andreas Langer
* Joe Perches
* Linus Lüssing
* Marek Lindner
* Randy Dunlap
* Simon Wunderlich
Special thanks goes to
* Kazuki Shimada
* Tim Glaremin
for extensive testing and debugging help. Lets see what the next months
will bring us.
Best regards,
Sven

[B.A.T.M.A.N.] [PATCH] batman-adv: Don't call unregister_netdev with locked rtnl semaphore
by Sven Eckelmann
We currently try to call unregister_netdev when we can destroy a softif
after all corresponding hard-interfaces announced that they will be
removed.
This will be done when we receive a hard_if_event which already takes
the rtnl semaphore and thus we try to get it again in unregister_netdev.
This results in a deadlock. This call to unregister_netdev cannot easily
replaced by unregister_netdevice, because other parts of the batman-adv
module still call that code indirectly without holding the rtnl
semaphore.
(needs rtln_unlocked)
unregister_netdev
^
|
softif_destroy
^
|
hardif_disable_interface
^ ^
/ |
store_mesh_iface hardif_remove_interface
(rtln_unlocked) ^ ^
| \
hardif_remove_interfaces hard_if_event
^ (rtln_locked)
|
batman_exit
(rtln_unlocked)
A consistent workaround is to change store_mesh_iface and
hardif_remove_interfaces to call rtnl_lock before they call the
mentioned child function, release the semaphore afterwards and change
unregister_netdev in softif_destroy to unregister_netdevice.

The thing is that code using NF_HOOK should be written in functional
paradigm: the recv() should be divided into 2 functions, before the NF_HOOK
and after. All after-nf work should be delegated to second part, not to code in
first part that is run after NF_HOOK return. It solves the problem of asyncronous
processing in hooks. It is perferctly seen in ipv4 ip_rcv() & rp_rcv_finish().

No, there isn't ;) In fact, for the caller of NF_HOOK() three cases may
happed:
1) All hooks return NF_ACCEPT or similar (NF_STOP or through
NF_QUEUE/NF_REPEAT with the same result). In this case ok_fn() is called
and code after return from NF_HOOK() is run.
In case of arp dev_queue_xmit() processes the skb and free it.
In your case ok_fn() does nothing and code after return from NF_HOOK()
finishes the processing of skb.
2) Some hook returns NF_DROP or similar (like (1), with the same
effect for the caller). In this case nf_hook_slow() frees skb and NF_HOOK()
returns -1. ok_fn() is not called at all.
Arp and batman don't leak anything as skb is freed.
3) Some hook returns NF_STOLEN signaling that now it is responsible for
skb delivery and freeing. It can be stolen until some long
calculations end or even some network communication is finished (e.g.
hook wants to know whether skb dest ip is google.com)
a) After some time the hook frees skb and doesn't call ok_fn().
arp and you don't leak anything and work exactly like NF_HOOK() retuned
NF_DROPPED.
b) After some time the hook finishes calcs and passes the skb to
ok_fn(). From this time ok_fn() is responsible for the skb.
In arp case it is dev_queue_xmit() that frees skb.
In batman case it does NOTHING and skb is leaked.
Also see the comment from linux/netfilter.h:
/* Activate hook; either okfn or kfree_skb called, unless a hook
returns NF_STOLEN (in which case, it's up to the hook to deal with
the consequences).
Returns -ERRNO if packet dropped. Zero means queued, stolen or
accepted.
*/
/* RR:

> about async and trust the return value to mean "packet was ok".
AK:
Just document it clearly, then you can expect some sense from kernel
coders :)

[B.A.T.M.A.N.] Staging: batman-adv for 2.6.36 (7: fixes)
by Sven Eckelmann
Hi,
here are patches targeted for 2.6.36. They are smaller bugfixes and add
no new features.
I already send you 5 Patches two weeks ago which fixes problems in 2.6.36 and
one of them also in 2.6.35, but got no reply till now. So here is the reminder
you asked me before.
The patches for 2.6.37 will follow later.
thanks,
Sven

[B.A.T.M.A.N.] Nat Question
by David Beaumont
I have a B.A.T.M.A.N mesh successfully configured on x86 hardware.
I can currently ping the internet from the router that is connected
via the mesh, however i can't download or connect to any webpages.
I see the request for the page going over the bat0 interface and being
received at the other end.
I've a feeling this is a basic nat problem, but have been unable to
find a solution.
I am using OpenWRT software.
Any advice? or hints?
Thanks

[B.A.T.M.A.N.] [PATCH] batman-adv: Don't write in not allocated packet_buff
by Sven Eckelmann
Each net_device in a system will automatically managed as a possible
batman_if and holds different informations like a buffer with a prepared
originator messages. To reduce the memory usage, the packet_buff will
only be allocated when the interface is really added/enabled for
batman-adv.
The function to update the hw address information inside the packet_buff
just assumes that the packet_buff is always initialised and thus the
kernel will just oops when we try to change the hw address of a not
already fully enabled interface.
We must always check if the packet_buff is allocated before we try to
change information inside of it.

the patch seems to work. Just did some basic testing and was able to
build up a network, even with the devices running older versions.
I will continue testing within the next few days, but now I need to
focus on creating a presentation for Wednesday.
I also added the output of dmesg:

Actually these patches are for devel aka the trunk. The patches I send to Tim
were for v2010.0.0. Please check if you really use the latest version of
batman-adv from trunk (see mareks reply to your message).
The trunk (r1776) has nearly all patches I've send around in the last week (at
least it should not have the problems you've experienced). Please try that
revision and please report back.
thanks,
