From 7b8f7a402d4cfc3a1361a2766066127f9bccadc4 Mon Sep 17 00:00:00 2001 From: Roopa Prabhu Date: Sun, 19 Mar 2017 22:01:28 -0700 Subject: neighbour: fix nlmsg_pid in notifications neigh notifications today carry pid 0 for nlmsg_pid in all cases. This patch fixes it to carry calling process pid when available. Applications (eg. quagga) rely on nlmsg_pid to ignore notifications generated by their own netlink operations. This patch follows the routing subsystem which already sets this correctly. Reported-by: Vivek Venkatraman Signed-off-by: Roopa Prabhu Signed-off-by: David S.
