With init_daemon_pid_file supporting class parameters, all calls to
init_daemon_run_dir can now be transformed into init_daemon_pid_file
calls.
Update the init_daemon_run_dir interface so it gives a warning when
used, and use the init_daemon_pid_file interface underlyingly.

For some daemons, it is the init script that is responsible for creating
the PID file of the daemon. As we do not want to update the init SELinux
policy module for each of these situations, we need to introduce an
interface that can be called by the SELinux policy module of the caller
(the daemon domain).
The initial suggestion was to transform the init_daemon_run_dir
interface, which offers a similar approach for directories in /run, into
a class-agnostic interface. Several names have been suggested, such as
init_script_spec_run_content or init_script_generic_run_filetrans_spec,
but in the end init_daemon_pid_file was used.
The interface requires the class(es) on which the file transition should
occur, like so:
init_daemon_pid_file(xdm_var_run_t, dir, "xdm")
init_daemon_pid_file(postgresql_var_run_t, file, "postgresql.pid")

Since commit 2d0c9cec mls_file_read_up and mls_file_write_down
interfaces are deprecated even though they are still present.
Replace mls_file_read_up with mls_file_read_all_levels and
mls_file_write_down with mls_file_write_all_levels.
Callers on init_run_daemon() role and domain transition on all
init_script_file_type to system_r and initrc_t respectively.
The old behavior of role and domain transitioning on init daemon entry
files was causing problems with programs that can be run both by system
and session.

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

Gentoo's OpenRC init framework handles the migration of data from /var/run to
/run, and /var/lock to /run/lock. To deal with this, openrc uses "cp -a -r
/var/run /run" and "cp -a -r /var/lock/* /run/lock".
When done, it will create symlinks in /var towards the new locations.
As a result, initrc_t needs to be able to manage symlinks in /var, as well as
manage all pidfile content (needed for the migration of /var/run/* towards
/run).

In Gentoo, the openrc init framework creates the /dev/shm location (within
devtmpfs) using a "mkdir -m 1777 /dev/shm" command. This results in initrc_t
wanting to set the attributes of the /dev/shm directory (at that point still
labeled device_t as tmpfs isn't mounted on it yet).

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.

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")

With udev now using /run for its data, the init script responsible for preparing
the environment to start up udev needs to be able to setup this location as
well.
We here allow init scripts to create the /run/udev location (transitioning to
udev_var_run_t) and manage this content (creating the /run/udev subdirectories).

At boot up, the /run location is empty, and init scripts are responsible for
creating the necessary structure within to support their services. This means,
adding entries like for the lock folder (/run/lock).

Recent init script packages allow for logging init script progress (service
start/stop state information, sometimes even duration, etc.) so we introduce an

When virsh is used to manage the virtual guests, the parent domain requires stream_connect rights towards the virtd_t

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.

udev_var_run_t is used for managing files in /etc/udev/rules.d as well as other files, including udev pid files. This patch creates a type specifically for rules.d files, and an interface for managing them. It also gives access to this type to initrc_t so that rules can be properly populated during startup. This also fixes a problem on Gentoo where udev rules are NOT properly populated on startup.

The latest revision of the labeled policy patches which enable both labeled
and unlabeled policy support for NetLabel. This revision takes into account
Chris' feedback from the first version and reduces the number of interface
calls in each domain down to two at present: one for unlabeled access, one for
NetLabel access. The older, transport layer specific interfaces, are still
present for use by third-party modules but are not used in the default policy
modules.
trunk: Use netmsg initial SID for MLS-only Netlabel packets, from Paul Moore.
This patch changes the policy to use the netmsg initial SID as the "base"
SID/context for NetLabel packets which only have MLS security attributes.
Currently we use the unlabeled initial SID which makes it very difficult to
distinquish between actual unlabeled packets and those packets which have MLS
security attributes.
- Allow semanage to read from /root on strict non-MLS for
local policy modules.
- Gentoo init script fixes for udev.
- Allow udev to read kernel modules.inputmap.
- Dnsmasq fixes from testing.
- Allow kernel NFS server to getattr filesystems so df can work
on clients.
Allow unconfined processes to see unlabeled processes in ps.
Removed a redundant rule in samba.te
Removed support for the pre-Fedora Red Hat code to create sym-links in /boot.
Removed support for devpts_t files in /tmp (there is no way that would ever
work).
Allowed postgrey to create socket files.
Made the specs for the /lib and /lib64 directories better support stem
compression.
