security: Remove rtnl_lock() in selinux_xfrm_notify_policyload()
rt_genid_bump_all() consists of ipv4 and ipv6 part. ipv4 part is incrementing of net::ipv4::rt_genid, and I see many places, where it's read without rtnl_lock(). ipv6 part calls __fib6_clean_all(), and it's also called without rtnl_lock() in other places. So, rtnl_lock() here was used to iterate net_namespace_list only, and we can remove it. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
