Subject: [PATCH] Allow sssd_kcm read and write z90crypt device
MIME-Version: 1.0

Reference: https://gitbub.com/fedora-selinux/selinux-policy/commit/80e7516c09c41c989176947265df41e39e94a31a
Conflict: NA

This permission is required on s390x systems with the Crypto Express
adapter card. The z90crypt device driver acts as the interface to the
PCI cryptography hardware and performs asynchronous encryption
operations (RSA) as used during the SSL handshake.

Addresses the following AVC denial:
