NAME

6       policykit_selinux  -  Security  Enhanced Linux Policy for the policykit
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the policykit  processes  via  flexible
11       mandatory access control.
12
13       The  policykit processes execute with the policykit_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep policykit_t
20
21
22

ENTRYPOINTS

24       The  policykit_t  SELinux  type can be entered via the policykit_exec_t
25       file type.
26
27       The default entrypoint paths for the policykit_t domain are the follow‐
28       ing:
29
30       /usr/libexec/polkitd.*,                /usr/libexec/polkit-1/polkitd.*,
31       /usr/lib/polkit-1/polkitd, /usr/lib/policykit/polkitd
32

PROCESS TYPES

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       policykit policy is very flexible allowing users to setup  their  poli‐
41       cykit processes in as secure a method as possible.
42
43       The following process types are defined for policykit:
44
45       policykit_t, policykit_auth_t, policykit_grant_t, policykit_resolve_t
46
47       Note:  semanage  permissive  -a  policykit_t  can  be  used to make the
48       process type policykit_t permissive. SELinux does not  deny  access  to
49       permissive  process  types,  but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least access  required.   poli‐
55       cykit  policy is extremely flexible and has several booleans that allow
56       you to manipulate the policy and run policykit with the tightest access
57       possible.

MANAGED FILES

172       The  SELinux process type policykit_t can manage files labeled with the
173       following file types.  The paths listed are the default paths for these
174       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

244       SELinux requires files to have an extended attribute to define the file
245       type.
246
247       You can see the context of a file using the -Z option to ls
248
249       Policy governs the access  confined  processes  have  to  these  files.
250       SELinux policykit policy is very flexible allowing users to setup their
251       policykit processes in as secure a method as possible.
252
253       EQUIVALENCE DIRECTORIES
254
255
256       policykit policy stores data with multiple different file context types
257       under the /var/lib/PolicyKit directory.  If you would like to store the
258       data in a different directory you can use the semanage command to  cre‐
259       ate an equivalence mapping.  If you wanted to store this data under the
260       /srv dirctory you would execute the following command:
261
262       semanage fcontext -a -e /var/lib/PolicyKit /srv/PolicyKit
263       restorecon -R -v /srv/PolicyKit
264
265       STANDARD FILE CONTEXT
266
267       SELinux defines the file context types for the policykit, if you wanted
268       to store files with these types in a diffent paths, you need to execute
269       the semanage command  to  sepecify  alternate  labeling  and  then  use
270       restorecon to put the labels on disk.
271
272       semanage  fcontext  -a  -t  policykit_var_run_t  '/srv/mypolicykit_con‐
273       tent(/.*)?'
274       restorecon -R -v /srv/mypolicykit_content
275
276       Note: SELinux often uses regular expressions  to  specify  labels  that
277       match multiple files.
278
279       The following file types are defined for policykit:
280
281
282
283       policykit_auth_exec_t
284
285       - Set files with the policykit_auth_exec_t type, if you want to transi‐
286       tion an executable to the policykit_auth_t domain.
287
288
289       Paths:
290            /usr/bin/pkla-check-authorization,  /usr/libexec/polkit-read-auth-
291            helper,   /usr/lib/polkit-1/polkit-agent-helper-1,  /usr/lib/poli‐
292            cykit/polkit-read-auth-helper, /usr/libexec/polkit-1/polkit-agent-
293            helper-1, /usr/libexec/kde4/polkit-kde-authentication-agent-1
294
295
296       policykit_exec_t
297
298       -  Set  files with the policykit_exec_t type, if you want to transition
299       an executable to the policykit_t domain.
300
301
302       Paths:
303            /usr/libexec/polkitd.*,           /usr/libexec/polkit-1/polkitd.*,
304            /usr/lib/polkit-1/polkitd, /usr/lib/policykit/polkitd
305
306
307       policykit_grant_exec_t
308
309       -  Set files with the policykit_grant_exec_t type, if you want to tran‐
310       sition an executable to the policykit_grant_t domain.
311
312
313       Paths:
314            /usr/libexec/polkit-grant-helper.*,     /usr/lib/policykit/polkit-
315            grant-helper.*
316
317
318       policykit_reload_t
319
320       -  Set files with the policykit_reload_t type, if you want to treat the
321       files as policykit reload data.
322
323
324
325       policykit_resolve_exec_t
326
327       - Set files with the policykit_resolve_exec_t  type,  if  you  want  to
328       transition an executable to the policykit_resolve_t domain.
329
330
331       Paths:
332            /usr/libexec/polkit-resolve-exe-helper.*,           /usr/lib/poli‐
333            cykit/polkit-resolve-exe-helper.*
334
335
336       policykit_tmp_t
337
338       - Set files with the policykit_tmp_t type, if you want to  store  poli‐
339       cykit temporary files in the /tmp directories.
340
341
342
343       policykit_var_lib_t
344
345       - Set files with the policykit_var_lib_t type, if you want to store the
346       policykit files under the /var/lib directory.
347
348
349       Paths:
350            /var/lib/polkit-1(/.*)?, /var/lib/PolicyKit(/.*)?,  /var/lib/Poli‐
351            cyKit-public(/.*)?
352
353
354       policykit_var_run_t
355
356       - Set files with the policykit_var_run_t type, if you want to store the
357       policykit files under the /run or /var/run directory.
358
359
360
361       Note: File context can be temporarily modified with the chcon  command.
362       If  you want to permanently change the file context you need to use the
363       semanage fcontext command.  This will modify the SELinux labeling data‐
364       base.  You will need to use restorecon to apply the labels.
365
366

COMMANDS

368       semanage  fcontext  can also be used to manipulate default file context
369       mappings.
370
371       semanage permissive can also be used to manipulate  whether  or  not  a
372       process type is permissive.
373
374       semanage  module can also be used to enable/disable/install/remove pol‐
375       icy modules.
376
377       semanage boolean can also be used to manipulate the booleans
378
379
380       system-config-selinux is a GUI tool available to customize SELinux pol‐
381       icy settings.
