Security-Enhanced Linux secures the games_srv processes via flexible mandatory access control.
The games_srv processes execute with the games_srv_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep games_srv_t
The games_srv_t SELinux type can be entered via the games_exec_t file type.
The default entrypoint paths for the games_srv_t domain are the following:
/usr/games/.*, /usr/lib/games(/.*)?, /usr/bin/civclient.*, /usr/bin/civserver.*, /usr/bin/sol, /usr/bin/kolf, /usr/bin/kpat, /usr/bin/micq, /usr/bin/gnect, /usr/bin/gtali, /usr/bin/iagno, /usr/bin/ksame, /usr/bin/ktron, /usr/bin/kwin4, /usr/bin/lskat, /usr/bin/gataxx, /usr/bin/glines, /usr/bin/klines, /usr/bin/kmines, /usr/bin/kpoker, /usr/bin/ksnake, /usr/bin/gnomine, /usr/bin/gnotski, /usr/bin/katomic, /usr/bin/kbounce, /usr/bin/kshisen, /usr/bin/ksirtet, /usr/bin/atlantik, /usr/bin/gnibbles, /usr/bin/gnobots2, /usr/bin/kenolaba, /usr/bin/klickety, /usr/bin/konquest, /usr/bin/kreversi, /usr/bin/ksokoban, /usr/bin/mahjongg, /usr/bin/Maelstrom, /usr/bin/blackjack, /usr/bin/gnotravex, /usr/bin/kblackbox, /usr/bin/kfouleggs, /usr/bin/kmahjongg, /usr/bin/kwin4proc, /usr/bin/lskatproc, /usr/bin/kasteroids, /usr/bin/ksmiletris, /usr/bin/kspaceduel, /usr/bin/ktuberling, /usr/bin/same-gnome, /usr/bin/kbackgammon, /usr/bin/kbattleship, /usr/bin/kgoldrunner, /usr/bin/gnome-stones, /usr/bin/kjumpingcube
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux games_srv policy is very flexible allowing users to setup their games_srv processes in as secure a method as possible.
The following process types are defined for games_srv:
Note: semanage permissive -a games_srv_t can be used to make the process type games_srv_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
The SELinux process type games_srv_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
