6 colord_selinux - Security Enhanced Linux Policy for the colord pro‐
7 cesses
8
10 Security-Enhanced Linux secures the colord processes via flexible
11 mandatory access control.
12
13 The colord processes execute with the colord_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep colord_t
20
21
22
24 The colord_t SELinux type can be entered via the colord_exec_t file
25 type.
26
27 The default entrypoint paths for the colord_t domain are the following:
28
29 /usr/lib/[^/]*/colord/colord, /usr/lib/[^/]*/colord/colord-sane,
30 /usr/libexec/colord, /usr/lib/colord/colord, /usr/libexec/colord-sane,
31 /usr/lib/colord/colord-sane
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 colord policy is very flexible allowing users to setup their colord
41 processes in as secure a method as possible.
42
43 The following process types are defined for colord:
44
45 colord_t
46
47 Note: semanage permissive -a colord_t can be used to make the process
48 type colord_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. colord
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run colord with the tightest access possible.
57
58
59
60 If you want to determine whether Colord can access nfs file systems,
61 you must turn on the colord_use_nfs boolean. Disabled by default.
62
63 setsebool -P colord_use_nfs 1
64
65
66
67 If you want to allow users to resolve user passwd entries directly from
68 ldap rather then using a sssd server, you must turn on the authlo‐
69 gin_nsswitch_use_ldap boolean. Disabled by default.
70
71 setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75 If you want to allow all domains to execute in fips_mode, you must turn
76 on the fips_mode boolean. Enabled by default.
77
78 setsebool -P fips_mode 1
79
80
81
82 If you want to allow confined applications to run with kerberos, you
83 must turn on the kerberos_enabled boolean. Enabled by default.
84
85 setsebool -P kerberos_enabled 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 nis_enabled boolean. Disabled by default.
91
92 setsebool -P nis_enabled 1
93
94
95
96 If you want to allow confined applications to use nscd shared memory,
97 you must turn on the nscd_use_shm boolean. Enabled by default.
98
99 setsebool -P nscd_use_shm 1
100
101
102
104 The SELinux process type colord_t can manage files labeled with the
105 following file types. The paths listed are the default paths for these
106 file types. Note the processes UID still need to have DAC permissions.

180 SELinux requires files to have an extended attribute to define the file
181 type.
182
183 You can see the context of a file using the -Z option to ls
184
185 Policy governs the access confined processes have to these files.
186 SELinux colord policy is very flexible allowing users to setup their
187 colord processes in as secure a method as possible.
188
189 EQUIVALENCE DIRECTORIES
190
191
192 colord policy stores data with multiple different file context types
193 under the /var/lib/color directory. If you would like to store the
194 data in a different directory you can use the semanage command to cre‐
195 ate an equivalence mapping. If you wanted to store this data under the
196 /srv dirctory you would execute the following command:
197
198 semanage fcontext -a -e /var/lib/color /srv/color
199 restorecon -R -v /srv/color
200
201 STANDARD FILE CONTEXT
202
203 SELinux defines the file context types for the colord, if you wanted to
204 store files with these types in a diffent paths, you need to execute
205 the semanage command to sepecify alternate labeling and then use
206 restorecon to put the labels on disk.
207
208 semanage fcontext -a -t colord_unit_file_t '/srv/mycolord_con‐
209 tent(/.*)?'
210 restorecon -R -v /srv/mycolord_content
211
212 Note: SELinux often uses regular expressions to specify labels that
213 match multiple files.
214
215 The following file types are defined for colord:
216
217
218
219 colord_exec_t
220
221 - Set files with the colord_exec_t type, if you want to transition an
222 executable to the colord_t domain.
223
224
225 Paths:
226 /usr/lib/[^/]*/colord/colord, /usr/lib/[^/]*/colord/colord-sane,
227 /usr/libexec/colord, /usr/lib/colord/colord, /usr/libexec/colord-
228 sane, /usr/lib/colord/colord-sane
229
230
231 colord_tmp_t
232
233 - Set files with the colord_tmp_t type, if you want to store colord
234 temporary files in the /tmp directories.
235
236
237
238 colord_tmpfs_t
239
240 - Set files with the colord_tmpfs_t type, if you want to store colord
241 files on a tmpfs file system.
242
243
244
245 colord_unit_file_t
246
247 - Set files with the colord_unit_file_t type, if you want to treat the
248 files as colord unit content.
249
250
251
252 colord_var_lib_t
253
254 - Set files with the colord_var_lib_t type, if you want to store the
255 colord files under the /var/lib directory.
256
257
258 Paths:
259 /var/lib/color(/.*)?, /var/lib/colord(/.*)?
260
261
262 Note: File context can be temporarily modified with the chcon command.
263 If you want to permanently change the file context you need to use the
264 semanage fcontext command. This will modify the SELinux labeling data‐
265 base. You will need to use restorecon to apply the labels.
266
267
269 semanage fcontext can also be used to manipulate default file context
270 mappings.
271
272 semanage permissive can also be used to manipulate whether or not a
273 process type is permissive.
274
275 semanage module can also be used to enable/disable/install/remove pol‐
276 icy modules.
277
278 semanage boolean can also be used to manipulate the booleans
279
280
281 system-config-selinux is a GUI tool available to customize SELinux pol‐
282 icy settings.
