The courier-imap and courier-pop3 daemons are started by sourcing their
configuration files, and then invoking the daemons using the proper options. If
this is done through a specialized script, then init only needs to call this
script (where a proper transition occurs) but if the init script itself does
this, it needs to be able to read the configuration files.

If the /var/lib/syslog directory does not exist, then syslog-ng (running in
syslogd_t) will attempt to create the directory.
Allow the syslogd_t domain to create the directory, and use an automatic file
transition towards syslogd_var_lib_t.
Also, the syslog-ng daemon uses a persistence file in
/var/lib/misc/syslog-ng.persist (and .persist- if it suspects a collision). As
/var/lib/misc is still a generic var_lib_t, we have the syslogd_t daemon write
its files as syslogd_var_lib_t therein.

Use the init_daemon_run_dir interface in order to allow initrc_t to create the
run dirs of the udev daemon with the proper file transition.
Signed-off-by: Sven Vermeulen <sven.vermeulen@siphos.be>
Due to the introduction of /run, many init scripts need to create the daemon run
dirs (such as /run/udev for the udev init script). To simplify this, we
introduce the "daemonrundir" attribute to which initrc_t has the necessary
create_dirs_perms granted. Because it often needs to change the attributes or
ownership of the directories as well, we also grant the setattr rights on the
directory.
Then, when needed, the modules can call this interface while adding the name of
the directory. This will trigger a named file transition when initrc_t creates
this directory:
init_daemon_run_dir(udev_var_run_t, "udev")
will trigger
files_pid_filetrans(initrc_t, udev_var_run_t, dir, "udev")

This directory contains the working files for updating network-related files
(like resolv.conf for name servers) before they are copied to the fixed
location. Although already in use previously, this location (/var/run/dhcpc or
/var/run/dhcpcd) was statically defined on the system.
With the introduction of /run and systems having /var/run -> /run, this is now a
dynamically created directory by dhcpc_t. Hence, the policy is enhanced allowing
dhcpc_t to create dhcpc_var_run_t directories, and include a file transition for
directories created in the var_run_t location(s).

With udev now using /run for its data, the init script responsible for preparing

We here allow init scripts to create the /run/udev location (transitioning to

Recent udev implementations now use /run (actually, /run/udev) for storing
database files, rules and more. Hence, we need to extend existing interfaces to
support searching through the udev_var_run_t location (as most of that was
previously only in device_t and/or etc_t or udev_etc_t)
Next to enhancing the interfaces, we provide additional ones that will be used
by the init script (for udev) which needs to create and support the new
/run/udev locations.

By default, any role attribute should be able to type their "own" types
that share the same prefix and used in the run interface. For example,
role newrole_roles types newrole_t;
so that the calling domain of the seutil_run_newrole() interface could
properly tansition into newrole_t. Without above role rule, the caller's
role won't be associated with newrole_t.
Other role attributes such as useradd_roles, groupadd_roles, chfn_roles
and run_init_roles should be fixed in the same way.
The unconfined user is currently not allowed to call portage-related
functions. However, in a targeted system (with unconfined domains
enabled), users (including administrators) should be allowed to
transition to the portage domain.
We position the portage-related calls outside the "ifdef(distro_gentoo)"
as other distributions support Portage as well.

allow semanage_t to work with fifo_files (needed for the command to

When an init script is launched, Gentoo's integrated run_init support
will re-execute /sbin/rc (an all-in-one binary) for various functions.
The run_init_t domain here should not be allowed to transition yet, so
we allow it to execute /sbin/rc without transitioning.

Within Gentoo, the init system (openrc) uses a single binary (/sbin/rc)
for all its functions, be it executing init scripts, managing runlevels,
checking state, etc. This binary is not allowed to be labeled
initrc_exec_t as that would trigger domain transitions where this isn't
necessary (or even allowed).
A suggested solution is to use a separate type declaration for /sbin/rc
(rc_exec_t) which transitions where necessary.
This patch includes support for the /sbin/rc rc_exec_t type and declares
the init_rc_exec() interface which allows domains to execute the binary
without transitioning.

This is intended to label /run/udev, but I am assuming that everyone
will use file_contexts.subs(_dist)? to substitute /var/run for /run,
since there are currently no other fcs for /run in refpolicy.
The label is udev_tbl_t instead of udev_var_run_t, because /run/udev
contains the data which used to be in /dev/.udev.
After a quick discussion with dominique, new attempt due to two issues:
1. No need (or even forbidden) to have "role $1 types foo_exec_t"
2. Suggestion to use the raid_run_mdadm name instead of raid_mdadm_role. The
idea here is to use raid_mdadm_role for prefixed domains (cfr. screen)
whereas raid_run_mdadm is to transition and run into a specific domain
Without wanting to (re?)start any discussion on prefixed versus non-prefixed
domains, such a naming convention could help us to keep the reference policy
cleaner (and naming conventions easy).
Also, refpolicy InterfaceNaming document only talks about run, not role.
So, without much further ado... ;-)
The system administrator (sysadm_r role) needs to use mdadm, but is not
allowed to use the mdadm_t type.
Rather than extend raid_domtrans_mdadm to allow this as well, use a
raid_mdadm_role (a bit more conform other role usages).
The other users of raid_domtrans_mdadm are all domains that run in system_r
role, which does have this type allowed (as per the system/raid.te
definition), so it wouldn't hurt to use raid_domtrans_mdadm for this.

I realized the policy wasn't complete for handling udev_tbl_t dirs, and
updating it wouldn't work because we couldn't make a filetrans on dirs,
since all the dirs in /dev would become udev_tbl_t. i.e. this would have
been required, but would make problems: dev_filetrans(udev_t, udev_tbl_t, dir);
Various changes to the Xen userspace policy, including:
- Add gntdev and gntalloc device node labeling.
- Create separate domains for blktap and qemu-dm rather than leaving them in xend_t.
- No need to allow xen userspace to create its own device nodes anymore;
this is handled automatically by the kernel/udev.
- No need to allow xen userspace access to generic raw storage; even if
using dedicated partitions/LVs for disk images, you can just label them
with xen_image_t.
The blktap and qemu-dm domains are stubs and will likely need to be
further expanded, but they should definitely not be left in xend_t. Not
sure if I should try to use qemu_domain_template() instead for qemu-dm,
but I don't see any current users of that template (qemu_t uses
virt_domain_template instead), and qemu-dm has specific interactions
with Xen.

The LVM subsystem uses system-wide semaphores for various activities.
Although the system boots properly without these (apart from the AVC denials
