NAME

6       gpg_selinux - Security Enhanced Linux Policy for the gpg processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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‐

MANAGED FILES

166       The  SELinux  process type gpg_t can manage files labeled with the fol‐
167       lowing file types.  The paths listed are the default  paths  for  these
168       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

243       SELinux requires files to have an extended attribute to define the file
244       type.
245
246       You can see the context of a file using the -Z option to ls
247
248       Policy governs the access  confined  processes  have  to  these  files.
249       SELinux  gpg  policy is very flexible allowing users to setup their gpg
250       processes in as secure a method as possible.
251
252       STANDARD FILE CONTEXT
253
254       SELinux defines the file context types for the gpg, if  you  wanted  to
255       store  files  with  these types in a diffent paths, you need to execute
256       the semanage command  to  sepecify  alternate  labeling  and  then  use
257       restorecon to put the labels on disk.
258
259       semanage fcontext -a -t gpg_secret_t '/srv/mygpg_content(/.*)?'
260       restorecon -R -v /srv/mygpg_content
261
262       Note:  SELinux  often  uses  regular expressions to specify labels that
263       match multiple files.
264
265       The following file types are defined for gpg:
266
267
268
269       gpg_agent_exec_t
270
271       - Set files with the gpg_agent_exec_t type, if you want  to  transition
272       an executable to the gpg_agent_t domain.
273
274
275
276       gpg_agent_tmp_t
277
278       -  Set  files  with  the gpg_agent_tmp_t type, if you want to store gpg
279       agent temporary files in the /tmp directories.
280
281
282
283       gpg_exec_t
284
285       - Set files with the gpg_exec_t type, if you want to transition an exe‐
286       cutable to the gpg_t domain.
287
288
289       Paths:
290            /usr/bin/gpg(2)?, /usr/lib/gnupg/.*, /usr/bin/gpgsm
291
292
293       gpg_helper_exec_t
294
295       -  Set files with the gpg_helper_exec_t type, if you want to transition
296       an executable to the gpg_helper_t domain.
297
298
299
300       gpg_pinentry_tmp_t
301
302       - Set files with the gpg_pinentry_tmp_t type, if you want to store  gpg
303       pinentry temporary files in the /tmp directories.
304
305
306
307       gpg_pinentry_tmpfs_t
308
309       -  Set  files  with the gpg_pinentry_tmpfs_t type, if you want to store
310       gpg pinentry files on a tmpfs file system.
311
312
313
314       gpg_secret_t
315
316       - Set files with the gpg_secret_t type, if you want to treat the  files
317       as gpg se secret data.
318
319
320       Paths:
321            /root/.gnupg(/.+)?,   /etc/mail/spamassassin/sa-update-keys(/.*)?,
322            /home/[^/]+/.gnupg(/.+)?
323
324
325       Note: File context can be temporarily modified with the chcon  command.
326       If  you want to permanently change the file context you need to use the
327       semanage fcontext command.  This will modify the SELinux labeling data‐
328       base.  You will need to use restorecon to apply the labels.
329
330

COMMANDS

332       semanage  fcontext  can also be used to manipulate default file context
333       mappings.
334
335       semanage permissive can also be used to manipulate  whether  or  not  a
336       process type is permissive.
337
338       semanage  module can also be used to enable/disable/install/remove pol‐
339       icy modules.
340
341       semanage boolean can also be used to manipulate the booleans
342
343
344       system-config-selinux is a GUI tool available to customize SELinux pol‐
345       icy settings.
