af_packet: de-inline some helper functions

This popped some compiler errors due to mismatched prototypes.

net: Add back alignment for size for __alloc_skb

Commit 87fb4b7b533073eeeaed0b6bf7c2328995f6c075 (net: more accurate skb truesize) changed the alignment of size.

net: add missing bh_unlock_sock() calls

2011-11-03T22:06:18Z

Simon Kirby reported lockdep warnings and following messages : [104661.897577] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? [104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? Problem comes from commit 0e734419 (ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.) If inet_csk_route_child_sock() returns NULL, we should release socket lock before freeing it. Another lock imbalance exists if __inet_inherit_port() returns an error since commit 093d282321da ( tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()) a backport is also needed for >= 2.6.37 kernels.

l2tp: fix race in l2tp_recv_dequeue()

2011-11-03T22:02:13Z

Misha Labjuk reported panics occurring in l2tp_recv_dequeue() If we release reorder_q.lock, we must not keep a dangling pointer (tmp), since another thread could manipulate reorder_q. Instead we must restart the scan at beginning of list. Reported-by: Misha Labjuk Tested-by: Misha Labjuk Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
