From f964629e3338d9e5a78c9b354380d5a1e2fa4617 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 29 Sep 2015 07:42:50 -0700 Subject: tcp: constify tcp_v{4|6}_route_req() sock argument These functions do not change the listener socket. Goal is to make sure tcp_conn_request() is not messing with listener in a racy way. Signed-off-by: Eric Dumazet Signed-off-by: David S.
