Bug #353

Description

———- Forwarded message ———-
From: David Miller davem@davemloft.net
Date: Fri, Apr 6, 2012 at 10:35 AM
Subject: [GIT] Networking
To: torvalds@linux-foundation.org
Cc: akpm@linux-foundation.org, netdev@vger.kernel.org,
linux-kernel@vger.kernel.org

1) Fix inaccuracies in network driver interface documentation, from
  Ben Hutchings.

2) Fix handling of negative offsets in BPF JITs, from Jan Seiffert.

3) Compile warning, locking, and refcounting fixes in netfilter’s
  xt_CT, from Pablo Neira Ayuso.

4) phonet sendmsg needs to validate user length just like any
  other datagram protocol, fix from Sasha Levin.

5) Ipv6 multicast code uses wrong loop index, from RongQing Li.

6) Link handling and firmware fixes in bnx2x driver from Yaniv
  Rosner and Yuval Mintz.

7) mlx4 erroneously allocates 4 pages at a time, regardless of page
  size, fix from Thadeu Lima de Souza Cascardo.

8) SCTP socket option wasn’t extended in a backwards compatible
  way, fix from Thomas Graf.

9) Add missing address change event emissions to bonding, from
  Shlomo Pongratz.

10) /proc/net/dev regressed because it uses a private offset to
   track where we are in the hash table, but this doesn’t
   track the offset pullback that the seq_file code does
   resulting in some entries being missed in large dumps.

   Fix from Eric Dumazet.

11) do_tcp_sendpage() unloads the send queue way too fast, because
   it invokes tcp_push() when it shouldn’t.  Let the natural sequence
   generated by the splice paths, and the assosciated MSG_MORE
   settings, guide the tcp_push() calls.

   Otherwise what goes out of TCP is spaghetti and doesn’t batch
   effectively into GSO/TSO clusters.

   From Eric Dumazet.

12) Once we put a SKB into either the netlink receiver’s queue
   or a socket error queue, it can be consumed and freed up,
   therefore we cannot touch it after queueing it like that.

   Fixes from Eric Dumazet.

13) PPP has this annoying behavior in that for every transmit
   call it immediately stops the TX queue, then calls down
   into the next layer to transmit the PPP frame.

   But if that next layer can take it immediately, it just
   un-stops the TX queue right before returning from the
   transmit method.

   Besides being useless work, it makes several facilities
   unusable, in particular things like the equalizers.  Well
   behaved devices should only stop the TX queue when they
   really are full, and in PPP’s case when it gets backlogged
   to the downstream device.

   David Woodhouse therefore fixed PPP to not stop the TX
   queue until it’s downstream can’t take data any more.

14) IFF_UNICAST_FLT got accidently lost in some recent stmmac
   driver changes, re-add.  From Marc Kleine-Budde.

15) Fix link flaps in ixgbe, from Eric W. Multanen.

16) Descriptor writeback fixes in e1000e from Matthew Vick.

Please pull, thanks a lot!
