2010-05-29IPv6: fix Mobile IPv6 regressionBrian Haley
Commit f4f914b5 (net: ipv6 bind to device issue) caused a regression with Mobile IPv6 when it changed the meaning of fl->oif to become a strict requirement of the route lookup. Instead, only force strict mode when sk->sk_bound_dev_if is set on the calling socket, getting the intended behavior and fixing the regression.

2010-05-28ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is usedVasanthakumar Thiagarajan
This bug was introduced by the following commit Author: Vasanthakumar Thiagarajan <vasanth@atheros.com> Date: Thu Apr 15 17:38:46 2010 -0400 ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(), this may result in a rate scaling with wrong feedback (number of unacked frames in this case). It is the last one in the chain of buffers for an aggregate frame that should be checked. Also it misses the initialization of this field in the buffer, this may lead to a situation where we stop the sw retransmission of failed subframes associated to this buffer.

The wrong size was being calculated for vfinfo.

2010-05-28ipv6: Add GSO support on forwarding pathHerbert Xu
Currently we disallow GSO packets on the IPv6 forward path. This patch fixes this. Note that I discovered that our existing GSO MTU checks (e.g., IPv4 forwarding) are buggy in that they skip the check altogether, when they really should be checking gso_size + header instead. I have also been lazy here in that I haven't bothered to segment the GSO packet by hand before generating an ICMP message. Someone should add that to be 100% correct.

2010-05-27net: fix lock_sock_bh/unlock_sock_bhEric Dumazet
This new sock lock primitive was introduced to speedup some user context socket manipulation. But it is unsafe to protect two threads, one using regular lock_sock/release_sock, one using lock_sock_bh/unlock_sock_bh This patch changes lock_sock_bh to be careful against 'owned' state. If owned is found to be set, we must take the slow path. lock_sock_bh() now returns a boolean to say if the slow path was taken, and this boolean is used at unlock_sock_bh time to call the appropriate unlock function. After this change, BH are either disabled or enabled during the lock_sock_bh/unlock_sock_bh protected section. This might be misleading, so we rename these functions to lock_sock_fast()/unlock_sock_fast().
