From 31048d7aedf31bf0f69c54a662944632f29d82f2 Mon Sep 17 00:00:00 2001 From: Stefan Baranoff Date: Sun, 15 Jul 2018 11:36:37 -0400 Subject: tcp: Fix broken repair socket window probe patch Correct previous bad attempt at allowing sockets to come out of TCP repair without sending window probes. To avoid changing size of the repair variable in struct tcp_sock, this lets the decision for sending probes or not to be made when coming out of repair by introducing two ways to turn it off. v2: * Remove erroneous comment; defines now make behavior clear Fixes: 70b7ff130224 ("tcp: allow user to create repair socket without window probes") Signed-off-by: Stefan Baranoff Signed-off-by: Eric Dumazet Acked-by: Andrei Vagin Signed-off-by: David S.
