From 6c3b8fc618905d7599dcc514c99ce4293d476f39 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Sat, 26 Jul 2008 17:51:06 -0700 Subject: [PATCH] netns: fix ip_rt_frag_needed rt_is_expired Running recent kernels, and using a particular vpn gateway, I've been having to edit my mails down to get them accepted by the smtp server. Git bisect led to commit e84f84f276473dcc673f360e8ff3203148bdf0e2 - netns: place rt_genid into struct net. The conversion from a != test to rt_is_expired() put one negative too many: and now my mail works. Signed-off-by: Hugh Dickins Acked-by: Denis V. Lunev Signed-off-by: David S.
