8e09ba5637 grant permission for rpm to write to audit log 
Messages like this are added to the audit log when an rpm is installed:
type=SOFTWARE_UPDATE msg=audit(1560913896.581:244): pid=1265 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:rpm_t:s0 msg='sw="ntpdate-4.2.6p5-25.el7_3.2.x86_64" sw_type=rpm key_enforce=0 gpg_res=0 root_dir="/" comm="rpm" exe="/usr/bin/rpm" hostname=? addr=?  terminal=? res=success'

These are the denials that I'm seeing:

51aadce3c2 Changes to support plymouth working in enforcing 
plymouth is started very early in the boot process.  Looks
like before the SELinux policy is loaded so plymouthd is
running as kernel_t rather than plymouthd_t.  Due to this
I needed to allow a few permissions on kernel_t to get
the system to boot.

ce570ab34d Label /sys/kernel/ns_last_pid as sysctl_kernel_ns_last_pid_t 
CRIU can influence the PID of the threads it wants to create.
CRIU uses /proc/sys/kernel/ns_last_pidto tell the kernel which
PID it wants for the next clone().
So it has to write to that file. This feels like a problematic as
it opens up the container writing to all sysctl_kernel_t.

Using new label container_t will just write to
sysctl_kernel_ns_last_pid_t instad writing to more generic
sysctl_kernel_t files.

ba31e59cd1 Separate out udevadm into a new domain 
This is the update I have made based on suggestions for the previous
patches to add a udev_run interface.  This adds the new domain udevadm_t
which is entered from /usr/bin/udevadm.

It seems to meet the needs that I have, but there are some things to
note that are probably important.
1) There are a few systemd services that use udevadm during startup.
   I have granted the permisssions that I need based on denials I was
   seeing during startup (the machine would fail to start without the
   permisions).
2) In the udev.fc file there are other binaries that I don't have on a
   RHEL7 box that maybe should also be labeled udevadm_exec_t.
   e.g. /usr/bin/udevinfo and /usr/bin/udevsend
   But as I don't have those binaries to test, I have not updated the
   type of that binary.
3) There are some places that call udev_domtrans that maybe should now
   be using udevadm_domtrans - rpm.te, hal.te, hotplug.te.  Again,
   these are not things that I am using in my current situation and am
   unable to test the interactions to know if the change is correct.

Other than that, I think this was a good suggestion to split udevadm
into a different domain.

Only change for v4 is to use stream_connect_pattern as suggested.

I'm seeing a many denials for cron related to faillog_t, lastlog_t
and wtmp_t.  These are all due to the fact cron is using pam (and my
system is configured with pam_faillog).  I have updated cron to use
auth_use_pam interface to grant needed permissions.

Additional change to allow systemd_logind dbus for cron.

I have included many of the denials I'm seeing, but there are probably
others I didn't capture.

59413b10b8 Allow AIDE to mmap files 
AIDE has a compile time option WITH_MMAP which allows AIDE to
map files during scanning.  RHEL7 has set this option in the
aide rpm they distribute.

Changes made to add a tunable to enable permissions allowing
aide to map files that it needs.  I have set the default to
false as this seems perfered (in my mind).

Remove a broad read-files rule for restorecond 
When the policy for restorecond was introduced, it contained a rule
which allowed restorecond to read every file except shadow_t (cf.
724925579d (diff-301316a33cafb23299e43112dc2bf2deR439)
):

    auth_read_all_files_except_shadow(restorecond_t)

Since 2006, the policy changed quite a bit, but this access remained.
However restorecond does not need to read every available file.

This is related to this comment:

Allow restorecond to read customizable_types

following AVC denial occurs:

    pid=281 comm="restorecond"
    path="/etc/selinux/refpolicy/contexts/customizable_types" dev="vda1"

    ino=928006 scontext=system_u:system_r:restorecond_t
    tcontext=system_u:object_r:default_context_t tclass=file
    permissive=1

As /etc/selinux/${SELINUXTYPE}/contexts/customizable_types is needed by
restorecond, allow this access.

Allow systemd-journald to use kill(pid, 0) on its clients 
Since systemd 241, systemd-journald is using kill(pid, 0) in order to
find dead processes and reduce its cache. The relevant commit is
91714a7f42
("journald: periodically drop cache for all dead PIDs"). This commit
added a call to pid_is_unwaited(c->pid), which is a function implemented in
https://github.com/systemd/systemd/blob/v241/src/basic/process-util.c#L936 :

    bool pid_is_unwaited(pid_t pid) {
        /* Checks whether a PID is still valid at all, including a zombie */
        if (pid < 0)
                return false;
        if (pid <= 1) /* If we or PID 1 would be dead and have been waited for, this code would not be running */
                return true;
        if (pid == getpid_cached())
                return true;
        if (kill(pid, 0) >= 0)
                return true;
        return errno != ESRCH;
    }

This new code triggers the following AVC denials:

    type=AVC msg=audit(1550911933.606:332): avc:  denied  { signull }
    for  pid=224 comm="systemd-journal"

81c10b077a New interface to dontaudit access to cert_t 
I'm seeing a bunch of denials for various processes (some refpolicy
domains, some my own application domains) attempting to access
/etc/pki.  They seem to be working OK even with the denial.  The
tunable authlogin_nsswitch_use_ldap controls access to cert_t
(for domains that are part of nsswitch_domain attribute).  Use this
new interface when that tunable is off to quiet the denials.
