Commit b2f5e7cd (ipv6: Fix conflict resolutions during ipv6 binding) introduced a regression where time-wait sockets were not treated correctly. This resulted in the following: BUG: unable to handle kernel NULL pointer dereference at 0000000000000062 IP: [<ffffffff805d7d61>] ipv4_rcv_saddr_equal+0x61/0x70 ...
