From f4713a3dfad045d46afcb9c2a7d0bba288920ed4 Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Wed, 26 Nov 2014 14:53:02 -0500 Subject: net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socks TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets. If the socket is of family AF_INET6, call ipv6_recv_error instead of ip_recv_error. This change is more complex than a single branch due to the loadable ipv6 module. It reuses a pre-existing indirect function call from ping. The ping code is safe to call, because it is part of the core ipv6 module and always present when AF_INET6 sockets are active. Fixes: 4ed2d765 (net-timestamp: TCP timestamping) Signed-off-by: Willem de Bruijn ---- It may also be worthwhile to add WARN_ON_ONCE(sk->family == AF_INET6) to ip_recv_error. Signed-off-by: David S.
