Miller Thu, 12 Jan 2006 08:32:13 -0800 [IPV6]: Avoid calling ip6_xmit() with NULL sk The ip6_xmit() function now assumes that its sk argument is non-NULL, which isn't currently true when TCPv6 code is sending RST or ACK packets. This fixes that code to use a socket of its own for sending such packets, as TCPv4 does. (Thanks Andi for the pointer). Signed-off-by: David Woodhouse Signed-off-by: David S. Miller
