From e01dcced45f895797dfba326bdb10d8d85e13eee Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Thu, 29 Nov 2007 23:07:57 +1100 Subject: XFRM: Fix leak of expired xfrm_states [XFRM]: Fix leak of expired xfrm_states [ Upstream commit: 5dba4797115c8fa05c1a4d12927a6ae0b33ffc41 ] The xfrm_timer calls __xfrm_state_delete, which drops the final reference manually without triggering destruction of the state. Change it to use xfrm_state_put to add the state to the gc list when we're dropping the last reference. The timer function may still continue to use the state safely since the final destruction does a del_timer_sync().
