On Arch Linux, OpenSSH unit files are:
/usr/lib/systemd/system/sshdgenkeys.service
/usr/lib/systemd/system/sshd.service
/usr/lib/systemd/system/sshd@.service
/usr/lib/systemd/system/sshd.socket
On Debian jessie, the unit files are:
/lib/systemd/system/ssh.service
/lib/systemd/system/ssh@.service
/lib/systemd/system/ssh.socket
On Fedora 22, the unit files are:
/usr/lib/systemd/system/sshd-keygen.service
/usr/lib/systemd/system/sshd.service
/usr/lib/systemd/system/sshd@.service
/usr/lib/systemd/system/sshd.socket
Use a pattern which matches every sshd unit and introduce an other type
for ssh-keygen units.
On Arch Linux, OpenSSH installs these binary files in /usr/lib/ssh:
* sftp-server (labeled with ssh_keysign_exec_t type in refpolicy)
* ssh-askpass (symlink to x11-ssh-askpass)
* ssh-keysign
* ssh-pkcs11-helper
* x11-ssh-askpass (from x11-ssh-askpass package)
Label all these files but sftp-server as bin_t.
On Arch Linux, /usr/bin/Xorg is only a shell script which executes
/usr/lib/xorg-server/Xorg.wrap, which is a SUID binary wrapper around
/usr/lib/xorg-server/Xorg.
Even though Xorg.wrap is not a full X server, it reads X11 configuration
files, uses the DRM interface to detect KMS, etc. (cf.
http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/xorg-wrapper.c?id=xorg-server-1.18.0
for more details). Therefore label it as xserver_exec_t.
This makes the following AVC appear:
denied { execute_no_trans } for pid=927 comm="X"
path="/usr/lib/xorg-server/Xorg.wrap" dev="dm-0" ino=3152592
scontext=system_u:system_r:xserver_t
tcontext=system_u:object_r:xserver_exec_t tclass=file
Allow /usr/bin/Xorg to execute Xorg.wrap with a can_exec statement.
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
Only for services that already have a named init script.
Add rules to init_startstop_service(), with conditional arg until
all of refpolicy-contrib callers are updated.
