Here is a patch which fixes an issue observed when using TCP over IPv6 and AH from IPsec. When a connection gets closed the 4-way method and the last ACK from the server gets dropped, the subsequent FINs from the client do not get ACKed because tcp_v6_send_response does not set the transport header pointer. This causes ah6_output to try to allocate a lot of memory, which typically fails, so the ACKs never make it out of the stack. I have reproduced the problem on kernel 2.6.7, but after looking at the latest kernel it seems the problem is still there. Signed-off-by:
