Subject: [PATCH 2/2] audit: block PERM fields being used with io_uring filtering
Date: Mon, 31 May 2021 09:44:55 -0400 [thread overview]
Message-ID: <8d1435a4b5db9139cc8eebce633f14872dd3a007.1622467740.git.rgb@redhat.com> (raw)
In-Reply-To: <CAHC9VhTr_hw_RBPf5yGD16j-qV2tbjjPJkimMNNQZBHtrJDbuQ@mail.gmail.com>
The commit ("audit: add filtering for io_uring records") added support for
filtering io_uring operations. The PERM field is invalid for io_uring
filtering, so block it.
