Debian's PAM configuration uses a patched pam_motd module that runs
files in /etc/update-motd.d/ in order to generate a dynamic Message Of
The Day (MOTD). By default, there is only one script:
$ cat /etc/update-motd.d/10-uname
#!/bin/sh
uname -snrvm
According to https://wiki.debian.org/motd, the script is executed
through run-parts:
if (!system("/usr/bin/env -i
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
run-parts --lsbsysinit /etc/update-motd.d >
/run/motd.dynamic.new"))
rename("/run/motd.dynamic.new", "/run/motd.dynamic");
This requires allowing pam_motd users to execute bin_t commands
(/usr/bin/env) and shells (/bin/sh), and to manage /run/motd.dynamic*
files.
Allow relevant accesses for Debian-based systems.

This patch is based on comments from previous a patch to
remove the many uses of kernel_dgram_send() and incorporate
it into logging_send_syslog_msg().
v2 - enclose in ifdef for redhat

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.

Remove complement (~) and wildcard (*) in allow rules so that there are no
unintentional additions when new permissions are declared.
This patch does not add or remove permissions from any rules.
This patch is slightly more involved than just running sed. It also adds
typealias rules and doesn't change the FC entries.
The /dev/apm_bios device doesn't exist on modern systems. I have left that
policy in for the moment on the principle of making one change per patch. But
I might send another patch to remove that as it won't exist with modern
kernels.
I have used optional sections for dbus and xserver as requested and also
fixed a minor issue of a rule not being in the correct section.
Please merge this.
Use nscd_use instead of nscd_socket_use. This conditionally allows
nscd_shm_use
Remove the nscd_socket_use from ssh_keygen since it was redundant
already allowed by auth_use_nsswitch
Had to make some ssh_keysign_t rules unconditional else
nscd_use(ssh_keysign_t) would not build (nested booleans) but that does
not matter, the only actual domain transition to ssh_keysign_t is
conditional so the other unconditional ssh_keygen_t rules are
conditional in practice
