[Patch net] act_ife: fix a potential use-after-free

2018-09-03 Thread Cong Wang

Immediately after module_put(), user could delete this module, so e->ops could be already freed before we call e->ops->release(). Fix this by moving module_put() after ops->release(). Fixes: ef6980b6becb ("introduce IFE action") Cc: Jamal Hadi Salim Signed-off-by: Cong Wang --- net/sched/act_i
