From 6443bb1fc2050ca2b6585a3fa77f7833b55329ed Mon Sep 17 00:00:00 2001 From: Eric Dumazet <eric.dumazet@gmail.com> Date: Sun, 25 Apr 2010 15:09:42 -0700 Subject: [PATCH] ipv6: Fix inet6_csk_bind_conflict() Commit fda48a0d7a84 (tcp: bind() fix when many ports are bound) introduced a bug on IPV6 part. We should not call ipv6_addr_any(inet6_rcv_saddr(sk2)) but ipv6_addr_any(inet6_rcv_saddr(sk)) because sk2 can be IPV4, while sk is IPV6. Reported-by: Michael S.
