Eric Dumazet 918eb39962 net: add missing bh_unlock_sock() calls ... 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 093d282321 ( tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()) a backport is also needed for >= 2.6.37 kernels.
