Subject: [PATCH] Allow systemd-io-bridge ioctl rpm_script_t
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reference: https://gitbub.com/fedora-selinux/selinux-policy/commit/3ecf12ffdad26ee5c6361a7c1e82ba507abdc04f
Conflict: NA

The permission to allow systemd-io-bridge ioctl rpm_script_t
with a unix domain stream socket was added to the policy.
It may be required when rpm packages are updated.

Addresses the following AVC denial:
