When cron_userdomain_transition boolean is set to on, the user cronjobs
are supposed to run in their domains. Without this patch the default
context is not properly computed:
$ /usr/sbin/getdefaultcon user_u system_u:system_r:crond_t:s0
/usr/sbin/getdefaultcon: Invalid argument
$ /usr/sbin/getdefaultcon staff_u system_u:system_r:crond_t:s0
staff_u:sysadm_r:sysadm_t:s0
With this patch applied:
$ /usr/sbin/getdefaultcon user_u system_u:system_r:crond_t:s0
user_u:user_r:user_t:s0
$ /usr/sbin/getdefaultcon staff_ system_u:system_r:crond_t:s0
staff_u:staff_r:staff_t:s0
Introduce the substitutions for the /usr/local/lib* locations (towards /usr/lib)
and /etc/init.d (towards /etc/rc.d/init.d).
Update the file contexts of the translated locations.
Rebased (collided with Guido's patch for commenting within the
file_contexts.subs_dist file) since v3.

Add a comment at the top of the configuration file file_contexts.subs_dist
to clarify that it performs aliasing and not substitutions in the
strict sense of the word.
A name change might be considered too, if it proves to lead to further
confusion.
There might be pieces of documentation that could benefit from similar
considerations.
Also note that a specific manual page is missing.
The libvirt infrastructure requires the availability of the context files.
In this patch, we add the defaults to the three predefined application
contexts (mls/mcs/standard).

When SELinux user system_u starts crond during system booting up, its
cron job process should be in the system_cronjob_t domain, which has
the required entrypoint permission on system crontab files labeled as
system_cron_spool_t. Otherwise we can run into below error messages:
Jan 31 08:40:53 QtCao crond[535]: (system_u) Unauthorized SELinux context (/etc/crontab)
Jan 31 08:40:53 QtCao crond[535]: (system_u) Unauthorized SELinux context (/etc/cron.d/sysstat)
The weird thing is that the getdefaultcon command even can not fetch
"system_r:cronjob_t:s0" but "system_r:logrotate_t:s0" ! After fixing
default_contexts files the getdefaultcon command could properly fetch
"system_r:system_cronjob_t:s0" :
root@QtCao:/root> getdefaultcon system_u system_u:system_r:crond_t:s0
system_u:system_r:logrotate_t:s0
root@QtCao:/root>
root@QtCao:/root> grep crond_t /etc/selinux/refpolicy-mls/contexts/default_contexts
system_r:crond_t:s0 user_r:cronjob_t:s0 staff_r:cronjob_t:s0 sysadm_r:cronjob_t:s0 system_r:system_cronjob_t:s0 unconfined_r:unconfined_cronjob_t:s0
root@QtCao:/root>
root@QtCao:/root> getdefaultcon system_u system_u:system_r:crond_t:s0
system_u:system_r:system_cronjob_t:s0

The attached patch adds sepgsql_contexts file into appconfig-*
directory. This configuration is used to initial labeling on
installation time for each database objects.
We can easily look up an appropriate label using selabel_loopup(3)
APIs. The 'sepgsql_contexts' is default for SE-PostgreSQL.
Thanks,

X Object manager policy revisions to x_contexts.
Many of the specific event, extension, and property types have been
removed for the time being. Polyinstantiation allows selections and
properties to be separated in a different way, and new X server support
for labeling individual extension requests (as opposed to entire extensions)
should make the extension querying problem easier to solve in the future.
