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,
36 /usr/bin/ksokoban, /usr/bin/mahjongg, /usr/bin/Maelstrom,
37 /usr/bin/blackjack, /usr/bin/gnotravex, /usr/bin/kblackbox,
38 /usr/bin/kfouleggs, /usr/bin/kmahjongg, /usr/bin/kwin4proc,

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. Enabled 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
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 /root/.cache/fontconfig(/.*)?
131 /home/[^/]+/.fontconfig(/.*)?
132 /home/[^/]+/.fonts/auto(/.*)?
133 /home/[^/]+/.fonts.cache-.*
134 /home/[^/]+/.cache/fontconfig(/.*)?
135
136
138 SELinux requires files to have an extended attribute to define the file
139 type.
140
141 You can see the context of a file using the -Z option to ls
142
143 Policy governs the access confined processes have to these files.
144 SELinux games policy is very flexible allowing users to setup their
145 games processes in as secure a method as possible.
146
147 STANDARD FILE CONTEXT
148
149 SELinux defines the file context types for the games, if you wanted to
150 store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use re‐
152 storecon to put the labels on disk.
153
154 semanage fcontext -a -t games_tmpfs_t '/srv/mygames_content(/.*)?'
155 restorecon -R -v /srv/mygames_content
156
157 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159
160 The following file types are defined for games:
161
162
163
164 games_data_t
165
166 - Set files with the games_data_t type, if you want to treat the files
167 as games content.
168
169
170 Paths:
171 /var/games(/.*)?, /var/lib/games(/.*)?
172
173
174 games_exec_t
175
176 - Set files with the games_exec_t type, if you want to transition an
177 executable to the games_t domain.
178
179
180 Paths:
181 /usr/games/.*, /usr/lib/games(/.*)?, /usr/bin/civclient.*,
182 /usr/bin/civserver.*, /usr/bin/sol, /usr/bin/kolf, /usr/bin/kpat,
183 /usr/bin/micq, /usr/bin/gnect, /usr/bin/gtali, /usr/bin/iagno,

197 /usr/bin/gnome-stones, /usr/bin/kjumpingcube
198
199
200 games_srv_var_run_t
201
202 - Set files with the games_srv_var_run_t type, if you want to store the
203 games srv files under the /run or /var/run directory.
204
205
206
207 games_tmp_t
208
209 - Set files with the games_tmp_t type, if you want to store games tem‐
210 porary files in the /tmp directories.
211
212
213
214 games_tmpfs_t
215
216 - Set files with the games_tmpfs_t type, if you want to store games
217 files on a tmpfs file system.
218
219
220
221 Note: File context can be temporarily modified with the chcon command.
222 If you want to permanently change the file context you need to use the
223 semanage fcontext command. This will modify the SELinux labeling data‐
224 base. You will need to use restorecon to apply the labels.
225
226
228 semanage fcontext can also be used to manipulate default file context
229 mappings.
230
231 semanage permissive can also be used to manipulate whether or not a
232 process type is permissive.
233
234 semanage module can also be used to enable/disable/install/remove pol‐
235 icy modules.
236
237 semanage boolean can also be used to manipulate the booleans
238
239
240 system-config-selinux is a GUI tool available to customize SELinux pol‐
241 icy settings.
