Subject: [PATCH] apparmor: fix an error code in __aa_create_ns()
Date: Thu, 02 Aug 2018 08:38:23 +0000	[thread overview]
Message-ID: <20180802083823.qrx5ieekfvtz2w4d@kili.mountain> (raw)

We should return error pointers in this function.  Returning NULL
results in a NULL dereference in the caller.

Fixes: 73688d1ed0b8 ("apparmor: refactor prepare_ns() and make usable from different views")
