NAME

6       spamc_selinux - Security Enhanced Linux Policy for the spamc processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The spamc_t SELinux type can be entered via the spamc_exec_t file type.
24
25       The default entrypoint paths for the spamc_t domain are the following:
26
27       /usr/bin/razor.*,  /usr/bin/spamc,  /usr/bin/pyzor,  /usr/bin/sa-learn,
28       /usr/bin/spamassassin
29

PROCESS TYPES

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

BOOLEANS

51       SELinux  policy  is customizable based on least access required.  spamc
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run spamc with the tightest access possible.

MANAGED FILES

189       The SELinux process type spamc_t can manage files labeled with the fol‐
190       lowing  file  types.   The paths listed are the default paths for these
191       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 spamc policy is very flexible allowing  users  to  setup  their
247       spamc processes in as secure a method as possible.
248
249       STANDARD FILE CONTEXT
250
251       SELinux  defines the file context types for the spamc, if you wanted to
252       store files with these types in a diffent paths, you  need  to  execute
253       the  semanage  command  to  sepecify  alternate  labeling  and then use
254       restorecon to put the labels on disk.
255
256       semanage fcontext -a -t spamc_tmp_t '/srv/myspamc_content(/.*)?'
257       restorecon -R -v /srv/myspamc_content
258
259       Note: SELinux often uses regular expressions  to  specify  labels  that
260       match multiple files.
261
262       The following file types are defined for spamc:
263
264
265
266       spamc_exec_t
267
268       -  Set  files  with the spamc_exec_t type, if you want to transition an
269       executable to the spamc_t domain.
270
271
272       Paths:
273            /usr/bin/razor.*,  /usr/bin/spamc,  /usr/bin/pyzor,   /usr/bin/sa-
274            learn, /usr/bin/spamassassin
275
276
277       spamc_home_t
278
279       -  Set  files  with  the  spamc_home_t type, if you want to store spamc
280       files in the users home directory.
281
282
283       Paths:
284            /root/.pyzor(/.*)?,    /root/.razor(/.*)?,     /root/.spamd(/.*)?,
285            /root/.spamassassin(/.*)?,               /home/[^/]+/.pyzor(/.*)?,
286            /home/[^/]+/.razor(/.*)?,                /home/[^/]+/.spamd(/.*)?,
287            /home/[^/]+/.spamassassin(/.*)?
288
289
290       spamc_tmp_t
291
292       -  Set files with the spamc_tmp_t type, if you want to store spamc tem‐
293       porary files in the /tmp directories.
294
295
296
297       Note: File context can be temporarily modified with the chcon  command.
298       If  you want to permanently change the file context you need to use the
299       semanage fcontext command.  This will modify the SELinux labeling data‐
300       base.  You will need to use restorecon to apply the labels.
301
302

COMMANDS

304       semanage  fcontext  can also be used to manipulate default file context
305       mappings.
306
307       semanage permissive can also be used to manipulate  whether  or  not  a
308       process type is permissive.
309
310       semanage  module can also be used to enable/disable/install/remove pol‐
311       icy modules.
312
313       semanage boolean can also be used to manipulate the booleans
314
315
316       system-config-selinux is a GUI tool available to customize SELinux pol‐
317       icy settings.
