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,

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.

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

216
217
218 games_srv_var_run_t
219
220 - Set files with the games_srv_var_run_t type, if you want to store the
221 games srv files under the /run or /var/run directory.
222
223
224
225 games_tmp_t
226
227 - Set files with the games_tmp_t type, if you want to store games tem‐
228 porary files in the /tmp directories.
229
230
231
232 games_tmpfs_t
233
234 - Set files with the games_tmpfs_t type, if you want to store games
235 files on a tmpfs file system.
236
237
238
239 Note: File context can be temporarily modified with the chcon command.
240 If you want to permanently change the file context you need to use the
241 semanage fcontext command. This will modify the SELinux labeling data‐
242 base. You will need to use restorecon to apply the labels.
243
244
246 semanage fcontext can also be used to manipulate default file context
247 mappings.
248
249 semanage permissive can also be used to manipulate whether or not a
250 process type is permissive.
251
252 semanage module can also be used to enable/disable/install/remove pol‐
253 icy modules.
254
255 semanage boolean can also be used to manipulate the booleans
256
257
258 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
