6 gpg_selinux - Security Enhanced Linux Policy for the gpg processes
7
9 Security-Enhanced Linux secures the gpg processes via flexible manda‐
10 tory access control.
11
12 The gpg processes execute with the gpg_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep gpg_t
19
20
21
23 The gpg_t SELinux type can be entered via the gpg_exec_t file type.
24
25 The default entrypoint paths for the gpg_t domain are the following:
26
27 /usr/bin/gpg(2)?, /usr/lib/gnupg/.*, /usr/bin/gpgsm
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 gpg policy is very flexible allowing users to setup their gpg processes
37 in as secure a method as possible.
38
39 The following process types are defined for gpg:
40
41 gpg_t, gpg_agent_t, gpg_helper_t, gpg_pinentry_t, gpg_web_t
42
43 Note: semanage permissive -a gpg_t can be used to make the process type
44 gpg_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
47
49 SELinux policy is customizable based on least access required. gpg
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run gpg with the tightest access possible.
52
53
54
55 If you want to allow users to resolve user passwd entries directly from
56 ldap rather then using a sssd server, you must turn on the authlo‐
57 gin_nsswitch_use_ldap boolean. Disabled by default.
58
59 setsebool -P authlogin_nsswitch_use_ldap 1
60
61
62
63 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65
66 setsebool -P fips_mode 1
67
68
69
70 If you want to allow confined applications to run with kerberos, you
71 must turn on the kerberos_enabled boolean. Disabled by default.
72
73 setsebool -P kerberos_enabled 1
74
75
76
77 If you want to allow system to run with NIS, you must turn on the
78 nis_enabled boolean. Disabled by default.
79
80 setsebool -P nis_enabled 1
81
82
83
84 If you want to allow confined applications to use nscd shared memory,
85 you must turn on the nscd_use_shm boolean. Disabled by default.
86
87 setsebool -P nscd_use_shm 1
88
89
90
92 The SELinux process type gpg_t can manage files labeled with the fol‐
93 lowing file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

168 SELinux requires files to have an extended attribute to define the file
169 type.
170
171 You can see the context of a file using the -Z option to ls
172
173 Policy governs the access confined processes have to these files.
174 SELinux gpg policy is very flexible allowing users to setup their gpg
175 processes in as secure a method as possible.
176
177 STANDARD FILE CONTEXT
178
179 SELinux defines the file context types for the gpg, if you wanted to
180 store files with these types in a diffent paths, you need to execute
181 the semanage command to sepecify alternate labeling and then use
182 restorecon to put the labels on disk.
183
184 semanage fcontext -a -t gpg_tmpfs_t '/srv/mygpg_content(/.*)?'
185 restorecon -R -v /srv/mygpg_content
186
187 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189
190 The following file types are defined for gpg:
191
192
193
194 gpg_agent_exec_t
195
196 - Set files with the gpg_agent_exec_t type, if you want to transition
197 an executable to the gpg_agent_t domain.
198
199
200
201 gpg_agent_tmp_t
202
203 - Set files with the gpg_agent_tmp_t type, if you want to store gpg
204 agent temporary files in the /tmp directories.
205
206
207
208 gpg_agent_tmpfs_t
209
210 - Set files with the gpg_agent_tmpfs_t type, if you want to store gpg
211 agent files on a tmpfs file system.
212
213
214
215 gpg_exec_t
216
217 - Set files with the gpg_exec_t type, if you want to transition an exe‐
218 cutable to the gpg_t domain.
219
220
221 Paths:
222 /usr/bin/gpg(2)?, /usr/lib/gnupg/.*, /usr/bin/gpgsm
223
224
225 gpg_helper_exec_t
226
227 - Set files with the gpg_helper_exec_t type, if you want to transition
228 an executable to the gpg_helper_t domain.
229
230
231
232 gpg_pinentry_tmp_t
233
234 - Set files with the gpg_pinentry_tmp_t type, if you want to store gpg
235 pinentry temporary files in the /tmp directories.
236
237
238
239 gpg_pinentry_tmpfs_t
240
241 - Set files with the gpg_pinentry_tmpfs_t type, if you want to store
242 gpg pinentry files on a tmpfs file system.
243
244
245
246 gpg_secret_t
247
248 - Set files with the gpg_secret_t type, if you want to treat the files
249 as gpg se secret data.
250
251
252 Paths:
253 /root/.gnupg(/.+)?, /etc/mail/spamassassin/sa-update-keys(/.*)?,
254 /home/[^/]+/.gnupg(/.+)?
255
256
257 gpg_tmpfs_t
258
259 - Set files with the gpg_tmpfs_t type, if you want to store gpg files
260 on a tmpfs file system.
261
262
263
264 Note: File context can be temporarily modified with the chcon command.
265 If you want to permanently change the file context you need to use the
266 semanage fcontext command. This will modify the SELinux labeling data‐
267 base. You will need to use restorecon to apply the labels.
268
269
271 semanage fcontext can also be used to manipulate default file context
272 mappings.
273
274 semanage permissive can also be used to manipulate whether or not a
275 process type is permissive.
276
277 semanage module can also be used to enable/disable/install/remove pol‐
278 icy modules.
279
280 semanage boolean can also be used to manipulate the booleans
281
282
283 system-config-selinux is a GUI tool available to customize SELinux pol‐
284 icy settings.
