From:   Russell Coker <russell@coker.com.au>
To:     selinux-refpolicy@vger.kernel.org
Subject: [PATCH] misc kernel patches
Message-ID: <YWFn+K8IjqQs/U4P@xev.coker.com.au>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

Allow systemd_nspawn_t to remount sysfs and stat cgroup.

Allow it to mounton the kernel symbol table and use systemd_nspawn_runtime_t
for named pipes.

Allow systemd_passwd_agent_t the sys_resource capability and access to sysfs.

Allow systemd_user_runtime_dir_t to delete user tmp dirs and named pipes.

Allow udevadm_t to stat cgroups and tmpfs.

Make certbot run in it's own domain from unconfined_t.

Added mounton_dir_perms and mounton_file_perms macros.

Change corenet_tcp_connect_generic_port to allow connecting to
unreserved_port_t as well as port_t.

Signed-off-by: Russell Coker <russell@coker.com.au>
