From 61e5744849cb936bf4361181b8f9ebccebf4d9db Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 30 Oct 2008 23:55:44 -0700 Subject: [PATCH] netfilter: nf_conntrack_proto_gre: switch to register_pernet_gen_subsys() register_pernet_gen_device() can't be used is nf_conntrack_pptp module is also used (compiled in or loaded). Right now, proto_gre_net_exit() is called before nf_conntrack_pptp_net_exit(). The former shutdowns and frees GRE piece of netns, however the latter absolutely needs it to flush keymap. Oops is inevitable. Switch to shiny new register_pernet_gen_subsys() to get correct ordering in netns ops list. Signed-off-by: Alexey Dobriyan Signed-off-by: Patrick McHardy Signed-off-by: David S.
