Subject: [PATCH][next] selinux: fix allocation failure check on newpolicy->sidtab
Date: Wed, 19 Aug 2020 11:42:56 +0100	[thread overview]
Message-ID: <20200819104256.51499-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The allocation check of newpolicy->sidtab is null checking if
newpolicy is null and not newpolicy->sidtab. Fix this.

Addresses-Coverity: ("Logically dead code")
Fixes: c7c556f1e81b ("selinux: refactor changing booleans")
