These are security parameters of the system found under /proc/sys/kernel. Allow **read** access is fine although our daemons normally shoudln't require this information (`cf-agent` is allowed this access already). Ticket: ENT-9684 Changelog: SELinux no longer blocks CFEngine deamons in reading security parameters from /proc/sys/kernel (cherry picked from commit 1ab8859)
Ticket: ENT-9727
Changelog: cf-hub is now allowed to use the TLS kernel module on
SELinux-enabled systems
(cherry picked from commit 982fb68)
On RHEL 9 there so-called dynamic users handled by systemd. httpd needs to be able access the related directory and socket to query user information. Ticket: ENT-9727 Changelog: None (cherry picked from commit 91bd050)
Allowing systemd to properly start and check our services, PostgreSQL to create and open the `/tmp/.s.PGSQL.5432.lock` file, ifconfig spawned by cf-hub to actually run as ifconfig_t, etc. Ticket: ENT-9727 Changelog: None (cherry picked from commit 3439279)
We need a different SELinux policy on RHEL 9 and RHEL 8 because the latter doesn't support all the types required by the policy for the former. Ticket: ENT-9727 Changelog: None (cherry picked from commit 3bf6540)
The type `systemd_userdbd_runtime_t` is only available on RHEL 9 and so RHEL 8 policy cannot contain it. Ticket: ENT-9727 Changelog: None (cherry picked from commit ba92b7b)
