Subject: [IPSEC]: xfrm audit hook misplaced in pfkey_delete and xfrm_del_sa
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16bec31db751030171b31d7767fa3a5bdbe980ea;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[IPSEC]: xfrm audit hook misplaced in pfkey_delete and xfrm_del_sa

Inside pfkey_delete and xfrm_del_sa the audit hooks were not called if
there was any permission/security failures in attempting to do the del
operation (such as permission denied from security_xfrm_state_delete).
This patch moves the audit hook to the exit path such that all failures
(and successes) will actually get audited.
