6 games_selinux - Security Enhanced Linux Policy for the games processes
7
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
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,
29 /usr/bin/micq, /usr/bin/gnect, /usr/bin/gtali, /usr/bin/iagno,
30 /usr/bin/ksame, /usr/bin/ktron, /usr/bin/kwin4, /usr/bin/lskat,
31 /usr/bin/gataxx, /usr/bin/glines, /usr/bin/klines, /usr/bin/kmines,
32 /usr/bin/kpoker, /usr/bin/ksnake, /usr/bin/gnomine, /usr/bin/gnotski,
33 /usr/bin/katomic, /usr/bin/kbounce, /usr/bin/kshisen, /usr/bin/ksirtet,
34 /usr/bin/atlantik, /usr/bin/gnibbles, /usr/bin/gnobots2, /usr/bin/keno‐
35 laba, /usr/bin/klickety, /usr/bin/konquest, /usr/bin/kreversi,

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
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. Disabled by
96 default.
97
98 setsebool -P selinuxuser_direct_dri_enabled 1
99
100
101
102 If you want to allows clients to write to the X server shared memory
103 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
104 abled by default.
105
106 setsebool -P xserver_clients_write_xshm 1
107
108
109
111 The SELinux process type games_t can manage files labeled with the fol‐
112 lowing file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.
114
115 games_data_t
116
117 /var/games(/.*)?
118 /var/lib/games(/.*)?
119
120 user_fonts_cache_t
121
122 /root/.fontconfig(/.*)?
123 /root/.fonts/auto(/.*)?
124 /root/.fonts.cache-.*
125 /root/.cache/fontconfig(/.*)?
126 /home/[^/]+/.fontconfig(/.*)?
127 /home/[^/]+/.fonts/auto(/.*)?
128 /home/[^/]+/.fonts.cache-.*
129 /home/[^/]+/.cache/fontconfig(/.*)?
130
131
133 SELinux requires files to have an extended attribute to define the file
134 type.
135
136 You can see the context of a file using the -Z option to ls
137
138 Policy governs the access confined processes have to these files.
139 SELinux games policy is very flexible allowing users to setup their
140 games processes in as secure a method as possible.
141
142 STANDARD FILE CONTEXT
143
144 SELinux defines the file context types for the games, if you wanted to
145 store files with these types in a diffent paths, you need to execute
146 the semanage command to sepecify alternate labeling and then use
147 restorecon to put the labels on disk.
148
149 semanage fcontext -a -t games_tmpfs_t '/srv/mygames_content(/.*)?'
150 restorecon -R -v /srv/mygames_content
151
152 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154
155 The following file types are defined for games:
156
157
158
159 games_data_t
160
161 - Set files with the games_data_t type, if you want to treat the files
162 as games content.
163
164
165 Paths:
166 /var/games(/.*)?, /var/lib/games(/.*)?
167
168
169 games_exec_t
170
171 - Set files with the games_exec_t type, if you want to transition an
172 executable to the games_t domain.
173
174
175 Paths:
176 /usr/games/.*, /usr/lib/games(/.*)?, /usr/bin/civclient.*,
177 /usr/bin/civserver.*, /usr/bin/sol, /usr/bin/kolf, /usr/bin/kpat,
178 /usr/bin/micq, /usr/bin/gnect, /usr/bin/gtali, /usr/bin/iagno,
179 /usr/bin/ksame, /usr/bin/ktron, /usr/bin/kwin4, /usr/bin/lskat,
180 /usr/bin/gataxx, /usr/bin/glines, /usr/bin/klines,
181 /usr/bin/kmines, /usr/bin/kpoker, /usr/bin/ksnake,
182 /usr/bin/gnomine, /usr/bin/gnotski, /usr/bin/katomic,
183 /usr/bin/kbounce, /usr/bin/kshisen, /usr/bin/ksirtet,
184 /usr/bin/atlantik, /usr/bin/gnibbles, /usr/bin/gnobots2,
185 /usr/bin/kenolaba, /usr/bin/klickety, /usr/bin/konquest,
186 /usr/bin/kreversi, /usr/bin/ksokoban, /usr/bin/mahjongg,
187 /usr/bin/Maelstrom, /usr/bin/blackjack, /usr/bin/gnotravex,
188 /usr/bin/kblackbox, /usr/bin/kfouleggs, /usr/bin/kmahjongg,
189 /usr/bin/kwin4proc, /usr/bin/lskatproc, /usr/bin/kasteroids,
190 /usr/bin/ksmiletris, /usr/bin/kspaceduel, /usr/bin/ktuberling,
191 /usr/bin/same-gnome, /usr/bin/kbackgammon, /usr/bin/kbattleship,
192 /usr/bin/kgoldrunner, /usr/bin/gnome-stones, /usr/bin/kjumpingcube
193
194
195 games_srv_var_run_t
196
197 - Set files with the games_srv_var_run_t type, if you want to store the
198 games srv files under the /run or /var/run directory.
199
200
201
202 games_tmp_t
203
204 - Set files with the games_tmp_t type, if you want to store games tem‐
205 porary files in the /tmp directories.
206
207
208
209 games_tmpfs_t
210
211 - Set files with the games_tmpfs_t type, if you want to store games
212 files on a tmpfs file system.
213
214
215
216 Note: File context can be temporarily modified with the chcon command.
217 If you want to permanently change the file context you need to use the
218 semanage fcontext command. This will modify the SELinux labeling data‐
219 base. You will need to use restorecon to apply the labels.
220
221
223 semanage fcontext can also be used to manipulate default file context
224 mappings.
225
226 semanage permissive can also be used to manipulate whether or not a
227 process type is permissive.
228
229 semanage module can also be used to enable/disable/install/remove pol‐
230 icy modules.
231
232 semanage boolean can also be used to manipulate the booleans
233
234
235 system-config-selinux is a GUI tool available to customize SELinux pol‐
236 icy settings.
