[PATCH 5.11 073/254] selinux: dont log MAC_POLICY_LOAD record on failed policy load
From: Greg Kroah-Hartman
Date: Mon Mar 29 2021 - 04:50:15 EST
From: Ondrej Mosnacek <omosnace@xxxxxxxxxx>
commit 519dad3bcd809dc1523bf80ab0310ddb3bf00ade upstream.
If sel_make_policy_nodes() fails, we should jump to 'out', not 'out1',
as the latter would incorrectly log an MAC_POLICY_LOAD audit record,
even though the policy hasn't actually been reloaded. The 'out1' jump
label now becomes unused and can be removed.
Fixes: 02a52c5c8c3b ("selinux: move policy commit after updating selinuxfs")
