NAME

6       procmail_selinux - Security Enhanced Linux Policy for the procmail pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  procmail  processes  via  flexible
11       mandatory access control.
12
13       The  procmail  processes  execute with the procmail_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 procmail_t
20
21
22

ENTRYPOINTS

24       The procmail_t SELinux type can be entered via the procmail_exec_t file
25       type.
26
27       The default entrypoint paths for the procmail_t domain are the  follow‐
28       ing:
29
30       /usr/bin/procmail
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       procmail policy is very flexible allowing users to setup their procmail
40       processes in as secure a method as possible.
41
42       The following process types are defined for procmail:
43
44       procmail_t
45
46       Note: semanage permissive -a procmail_t can be used to make the process
47       type  procmail_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  proc‐
54       mail policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run procmail with the tightest access
56       possible.

MANAGED FILES

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

FILE CONTEXTS

240       SELinux requires files to have an extended attribute to define the file
241       type.
242
243       You can see the context of a file using the -Z option to ls
244
245       Policy  governs  the  access  confined  processes  have to these files.
246       SELinux procmail policy is very flexible allowing users to setup  their
247       procmail processes in as secure a method as possible.
248
249       EQUIVALENCE DIRECTORIES
250
251
252       procmail  policy stores data with multiple different file context types
253       under the /var/log/procmail directory.  If you would like to store  the
254       data  in a different directory you can use the semanage command to cre‐
255       ate an equivalence mapping.  If you wanted to store this data under the
256       /srv dirctory you would execute the following command:
257
258       semanage fcontext -a -e /var/log/procmail /srv/procmail
259       restorecon -R -v /srv/procmail
260
261       STANDARD FILE CONTEXT
262
263       SELinux  defines the file context types for the procmail, if you wanted
264       to store files with these types in a diffent paths, you need to execute
265       the  semanage  command  to  sepecify  alternate  labeling  and then use
266       restorecon to put the labels on disk.
267
268       semanage fcontext -a -t procmail_tmp_t '/srv/myprocmail_content(/.*)?'
269       restorecon -R -v /srv/myprocmail_content
270
271       Note: SELinux often uses regular expressions  to  specify  labels  that
272       match multiple files.
273
274       The following file types are defined for procmail:
275
276
277
278       procmail_exec_t
279
280       - Set files with the procmail_exec_t type, if you want to transition an
281       executable to the procmail_t domain.
282
283
284
285       procmail_home_t
286
287       - Set files with the procmail_home_t type, if you want to  store  proc‐
288       mail files in the users home directory.
289
290
291       Paths:
292            /root/.procmailrc, /home/[^/]+/.procmailrc
293
294
295       procmail_log_t
296
297       - Set files with the procmail_log_t type, if you want to treat the data
298       as procmail log data, usually stored under the /var/log directory.
299
300
301       Paths:
302            /var/log/procmail(/.*)?, /var/log/procmail.log.*
303
304
305       procmail_tmp_t
306
307       - Set files with the procmail_tmp_t type, if you want to store procmail
308       temporary files in the /tmp directories.
309
310
311
312       Note:  File context can be temporarily modified with the chcon command.
313       If you want to permanently change the file context you need to use  the
314       semanage fcontext command.  This will modify the SELinux labeling data‐
315       base.  You will need to use restorecon to apply the labels.
316
317

COMMANDS

319       semanage fcontext can also be used to manipulate default  file  context
320       mappings.
321
322       semanage  permissive  can  also  be used to manipulate whether or not a
323       process type is permissive.
324
325       semanage module can also be used to enable/disable/install/remove  pol‐
326       icy modules.
327
328       semanage boolean can also be used to manipulate the booleans
329
330
331       system-config-selinux is a GUI tool available to customize SELinux pol‐
332       icy settings.
