Subject: [NETNS]: Double free in netlink_release.
X-Git-Tag: v2.6.25-rc1~1162^2~274

[NETNS]: Double free in netlink_release.

Netlink protocol table is global for all namespaces. Some netlink
protocols have been virtualized, i.e. they have per/namespace netlink
socket. This difference can easily lead to double free if more than 1
namespace is started. Count the number of kernel netlink sockets to
track that this table is not used any more.
