From 539fae89bebd16ebeafd57a87169bc56eb530d76 Mon Sep 17 00:00:00 2001 From: Patrick McManus Date: Fri, 21 Mar 2008 16:27:38 -0700 Subject: [PATCH] [TCP]: TCP_DEFER_ACCEPT updates - defer timeout conflicts with max_thresh timeout associated with SO_DEFER_ACCEPT wasn't being honored if it was less than the timeout allowed by the maximum syn-recv queue size algorithm. Fix by using the SO_DEFER_ACCEPT value if the ack has arrived. Signed-off-by: Patrick McManus Acked-by: Eric Dumazet Signed-off-by: David S.
