[linux-next] LinuxNextTracking branch, master, updated. next-20181119
by batman＠open-mesh.org
The following commit has been merged in the master branch:
commit d7d8bbb40a5b1f682ee6589e212934f4c6b8ad60
Author: Sven Eckelmann <sven(a)narfation.org>
Date: Wed Nov 7 23:09:12 2018 +0100
batman-adv: Expand merged fragment buffer for full packet
The complete size ("total_size") of the fragmented packet is stored in the
fragment header and in the size of the fragment chain. When the fragments
are ready for merge, the skbuff's tail of the first fragment is expanded to
have enough room after the data pointer for at least total_size. This means
that it gets expanded by total_size - first_skb->len.
But this is ignoring the fact that after expanding the buffer, the fragment
header is pulled by from this buffer. Assuming that the tailroom of the
buffer was already 0, the buffer after the data pointer of the skbuff is
now only total_size - len(fragment_header) large. When the merge function
is then processing the remaining fragments, the code to copy the data over
to the merged skbuff will cause an skb_over_panic when it tries to actually
put enough data to fill the total_size bytes of the packet.
The size of the skb_pull must therefore also be taken into account when the
buffer's tailroom is expanded.

+ This will prevent the compiler from optimizing the kernel by

+ With this option, only functions explicitly marked with

batman-adv: Use explicit tvlv padding for ELP packets
The announcement messages of batman-adv COMPAT_VERSION 15 have the
possibility to announce additional information via a dynamic TVLV part.
This part is optional for the ELP packets and currently not parsed by the
Linux implementation. Still out-of-tree versions are using it to transport
things like neighbor hashes to optimize the rebroadcast behavior.
Since the ELP broadcast packets are smaller than the minimal ethernet
packet, it often has to be padded. This is often done (as specified in
RFC894) with octets of zero and thus work perfectly fine with the TVLV
part (making it a zero length and thus empty). But not all ethernet
compatible hardware seems to follow this advice. To avoid ambiguous
situations when parsing the TVLV header, just force the 4 bytes (TVLV
length + padding) after the required ELP header to zero.

batman-adv: enable MCAST by default at compile time
Thanks to rigorous testing in wireless community mesh networks several
issues with multicast entries in the translation table were found and
fixed in the last 1.5 years. Now we see the first larger networks
(a few hundred nodes) with a batman-adv version with multicast
optimizations enabled arising, with no TT / multicast optimization
related issues so far.
Therefore it seems safe to enable multicast optimizations by default.

The commit ced72933a5e8 ("batman-adv: use CRC32C instead of CRC16 in TT

(optional) bridge loop avoidance code is the only user of this function.
batman-adv should only select CRC16 when it is actually using it.

batman-adv: Add inconsistent local TT netlink dump detection
The netlink dump functionality transfers a large number of entries from the
kernel to userspace. It is rather likely that the transfer has to
interrupted and later continued. During that time, it can happen that
either new entries are added or removed. The userspace could than either
receive some entries multiple times or miss entries.
Commit 670dc2833d14 ("netlink: advertise incomplete dumps") introduced a
mechanism to inform userspace about this problem. Userspace can then decide
whether it is necessary or not to retry dumping the information again.
The netlink dump functions have to be switched to exclusive locks to avoid
changes while the current message is prepared. The already existing
generation sequence counter from the hash helper can be used for this
simple hash.
