NAME

6       games_selinux - Security Enhanced Linux Policy for the games processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the games processes via flexible manda‐
10       tory access control.
11
12       The games processes execute with the  games_t  SELinux  type.  You  can
13       check  if  you have these processes running by executing the ps command
14       with the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep games_t
19
20
21

ENTRYPOINTS

23       The games_t SELinux type can be entered via the games_exec_t file type.
24
25       The default entrypoint paths for the games_t domain are the following:
26
27       /usr/games/.*,       /usr/lib/games(/.*)?,        /usr/bin/civclient.*,
28       /usr/bin/civserver.*,   /usr/bin/sol,   /usr/bin/kolf,   /usr/bin/kpat,

34       /usr/bin/atlantik, /usr/bin/gnibbles, /usr/bin/gnobots2, /usr/bin/keno‐
35       laba,    /usr/bin/klickety,    /usr/bin/konquest,    /usr/bin/kreversi,
36       /usr/bin/ksokoban,        /usr/bin/mahjongg,        /usr/bin/Maelstrom,

PROCESS TYPES

45       SELinux defines process types (domains) for each process running on the
46       system
47
48       You can see the context of a process using the -Z option to ps
49
50       Policy governs the access confined processes have  to  files.   SELinux
51       games  policy is very flexible allowing users to setup their games pro‐
52       cesses in as secure a method as possible.
53
54       The following process types are defined for games:
55
56       games_t, games_srv_t
57
58       Note: semanage permissive -a games_t can be used to  make  the  process
59       type  games_t  permissive.  SELinux  does not deny access to permissive
60       process types, but the AVC (SELinux denials) messages are still  gener‐
61       ated.
62
63

BOOLEANS

65       SELinux  policy  is customizable based on least access required.  games
66       policy is extremely flexible and has several booleans that allow you to
67       manipulate the policy and run games with the tightest access possible.
68
69
70
71       If you want to deny user domains applications to map a memory region as
72       both executable and writable, this  is  dangerous  and  the  executable
73       should be reported in bugzilla, you must turn on the deny_execmem bool‐
74       ean. Enabled by default.
75
76       setsebool -P deny_execmem 1
77
78
79
80       If you want to allow all domains to execute in fips_mode, you must turn
81       on the fips_mode boolean. Enabled by default.
82
83       setsebool -P fips_mode 1
84
85
86
87       If  you  want to allow confined applications to use nscd shared memory,
88       you must turn on the nscd_use_shm boolean. Disabled by default.
89
90       setsebool -P nscd_use_shm 1
91
92
93
94       If you want to allow regular users direct dri device access,  you  must
95       turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
96
97       setsebool -P selinuxuser_direct_dri_enabled 1
98
99
100
101       If  you  want  to allows clients to write to the X server shared memory
102       segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
103       abled by default.
104
105       setsebool -P xserver_clients_write_xshm 1
106
107
108

MANAGED FILES

110       The SELinux process type games_t can manage files labeled with the fol‐
111       lowing file types.  The paths listed are the default  paths  for  these
112       file types.  Note the processes UID still need to have DAC permissions.
113
114       games_data_t
115
116            /var/games(/.*)?
117            /var/lib/games(/.*)?
118
119       games_tmp_t
120
121
122       games_tmpfs_t
123
124
125       user_fonts_cache_t
126
127            /root/.fontconfig(/.*)?
128            /root/.fonts/auto(/.*)?
129            /root/.fonts.cache-.*
130            /home/[^/]+/.fontconfig(/.*)?

FILE CONTEXTS

153       SELinux requires files to have an extended attribute to define the file
154       type.
155
156       You can see the context of a file using the -Z option to ls
157
158       Policy governs the access  confined  processes  have  to  these  files.
159       SELinux  games  policy  is  very flexible allowing users to setup their
160       games processes in as secure a method as possible.
161
162       STANDARD FILE CONTEXT
163
164       SELinux defines the file context types for the games, if you wanted  to
165       store  files  with  these types in a diffent paths, you need to execute
166       the semanage command  to  sepecify  alternate  labeling  and  then  use
167       restorecon to put the labels on disk.
168
169       semanage fcontext -a -t games_tmpfs_t '/srv/mygames_content(/.*)?'
170       restorecon -R -v /srv/mygames_content
171
172       Note:  SELinux  often  uses  regular expressions to specify labels that
173       match multiple files.
174
175       The following file types are defined for games:
176
177
178
179       games_data_t
180
181       - Set files with the games_data_t type, if you want to treat the  files
182       as games content.
183
184
185       Paths:
186            /var/games(/.*)?, /var/lib/games(/.*)?
187
188
189       games_exec_t
190
191       -  Set  files  with the games_exec_t type, if you want to transition an
192       executable to the games_t domain.
193
194
195       Paths:
196            /usr/games/.*,     /usr/lib/games(/.*)?,     /usr/bin/civclient.*,
197            /usr/bin/civserver.*,  /usr/bin/sol, /usr/bin/kolf, /usr/bin/kpat,

199            /usr/bin/ksame,  /usr/bin/ktron,  /usr/bin/kwin4,  /usr/bin/lskat,
200            /usr/bin/gataxx,         /usr/bin/glines,         /usr/bin/klines,
201            /usr/bin/kmines,         /usr/bin/kpoker,         /usr/bin/ksnake,
202            /usr/bin/gnomine,       /usr/bin/gnotski,        /usr/bin/katomic,
203            /usr/bin/kbounce,        /usr/bin/kshisen,       /usr/bin/ksirtet,
204            /usr/bin/atlantik,      /usr/bin/gnibbles,      /usr/bin/gnobots2,
205            /usr/bin/kenolaba,      /usr/bin/klickety,      /usr/bin/konquest,
206            /usr/bin/kreversi,      /usr/bin/ksokoban,      /usr/bin/mahjongg,
207            /usr/bin/Maelstrom,     /usr/bin/blackjack,    /usr/bin/gnotravex,
208            /usr/bin/kblackbox,    /usr/bin/kfouleggs,     /usr/bin/kmahjongg,
209            /usr/bin/kwin4proc,    /usr/bin/lskatproc,    /usr/bin/kasteroids,

212            /usr/bin/kgoldrunner, /usr/bin/gnome-stones, /usr/bin/kjumpingcube
213
214
215       games_srv_var_run_t
216
217       - Set files with the games_srv_var_run_t type, if you want to store the
218       games srv files under the /run or /var/run directory.
219
220
221
222       games_tmp_t
223
224       -  Set files with the games_tmp_t type, if you want to store games tem‐
225       porary files in the /tmp directories.
226
227
228
229       games_tmpfs_t
230
231       - Set files with the games_tmpfs_t type, if you  want  to  store  games
232       files on a tmpfs file system.
233
234
235
236       Note:  File context can be temporarily modified with the chcon command.
237       If you want to permanently change the file context you need to use  the
238       semanage fcontext command.  This will modify the SELinux labeling data‐
239       base.  You will need to use restorecon to apply the labels.
240
241

COMMANDS

243       semanage fcontext can also be used to manipulate default  file  context
244       mappings.
245
246       semanage  permissive  can  also  be used to manipulate whether or not a
247       process type is permissive.
248
249       semanage module can also be used to enable/disable/install/remove  pol‐
250       icy modules.
251
252       semanage boolean can also be used to manipulate the booleans
253
254
255       system-config-selinux is a GUI tool available to customize SELinux pol‐
256       icy settings.
