Subject: [NETNS]: Memory leak on network namespace stop.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4f84d82f7a623f8641af2574425c329431ff158f;p=linux-beck.git

[NETNS]: Memory leak on network namespace stop.

Network namespace allocates 2 kernel netlink sockets, fibnl &
rtnl. These sockets should be disposed properly, i.e. by
sock_release. Plain sock_put is not enough.
