From 49a496c97d035f2eab7cef4894dd46202184fc81 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 5 Nov 2015 12:50:19 -0800 Subject: tcp: use correct req pointer in tcp_move_syn() calls I mistakenly took wrong request sock pointer when calling tcp_move_syn() @req_unhash is either a copy of @req, or a NULL value for FastOpen connexions (as we do not expect to unhash the temporary request sock from ehash table) Fixes: 805c4bc05705 ("tcp: fix req->saved_syn race") Signed-off-by: Eric Dumazet Cc: Ying Cai Signed-off-by: David S.
