NAME

6       abrt_selinux - Security Enhanced Linux Policy for the abrt processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The abrt_t SELinux type can be entered via the abrt_exec_t file type.
24
25       The default entrypoint paths for the abrt_t domain are the following:
26
27       /usr/sbin/abrtd
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       abrt policy is very flexible allowing users to setup  their  abrt  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for abrt:
40
41       abrt_handle_event_t, abrt_helper_t, abrt_retrace_coredump_t, abrt_t, abrt_retrace_worker_t, abrt_dump_oops_t
42
43       Note:  semanage  permissive  -a  abrt_t can be used to make the process
44       type abrt_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

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

MANAGED FILES

158       The  SELinux process type abrt_t can manage files labeled with the fol‐
159       lowing file types.  The paths listed are the default  paths  for  these
160       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

267       SELinux requires files to have an extended attribute to define the file
268       type.
269
270       You can see the context of a file using the -Z option to ls
271
272       Policy governs the access  confined  processes  have  to  these  files.
273       SELinux abrt policy is very flexible allowing users to setup their abrt
274       processes in as secure a method as possible.
275
276       EQUIVALENCE DIRECTORIES
277
278
279       abrt policy stores data with  multiple  different  file  context  types
280       under  the  /var/cache/abrt  directory.  If you would like to store the
281       data in a different directory you can use the semanage command to  cre‐
282       ate an equivalence mapping.  If you wanted to store this data under the
283       /srv dirctory you would execute the following command:
284
285       semanage fcontext -a -e /var/cache/abrt /srv/abrt
286       restorecon -R -v /srv/abrt
287
288       abrt policy stores data with  multiple  different  file  context  types
289       under  the  /var/spool/abrt  directory.  If you would like to store the
290       data in a different directory you can use the semanage command to  cre‐
291       ate an equivalence mapping.  If you wanted to store this data under the
292       /srv dirctory you would execute the following command:
293
294       semanage fcontext -a -e /var/spool/abrt /srv/abrt
295       restorecon -R -v /srv/abrt
296
297       abrt policy stores data with  multiple  different  file  context  types
298       under the /var/run/abrt directory.  If you would like to store the data
299       in a different directory you can use the semanage command to create  an
300       equivalence  mapping.   If you wanted to store this data under the /srv
301       dirctory you would execute the following command:
302
303       semanage fcontext -a -e /var/run/abrt /srv/abrt
304       restorecon -R -v /srv/abrt
305
306       STANDARD FILE CONTEXT
307
308       SELinux defines the file context types for the abrt, if you  wanted  to
309       store  files  with  these types in a diffent paths, you need to execute
310       the semanage command  to  sepecify  alternate  labeling  and  then  use
311       restorecon to put the labels on disk.
312
313       semanage fcontext -a -t abrt_var_run_t '/srv/myabrt_content(/.*)?'
314       restorecon -R -v /srv/myabrt_content
315
316       Note:  SELinux  often  uses  regular expressions to specify labels that
317       match multiple files.
318
319       The following file types are defined for abrt:
320
321
322
323       abrt_dump_oops_exec_t
324
325       - Set files with the abrt_dump_oops_exec_t type, if you want to transi‐

401
402
403       abrt_tmp_t
404
405       -  Set files with the abrt_tmp_t type, if you want to store abrt tempo‐
406       rary files in the /tmp directories.

409
410       abrt_var_cache_t
411

436            /var/run/abrt.pid
437
438
439       Note:  File context can be temporarily modified with the chcon command.
440       If you want to permanently change the file context you need to use  the
441       semanage fcontext command.  This will modify the SELinux labeling data‐
442       base.  You will need to use restorecon to apply the labels.
443
444

SHARING FILES

446       If you want to share files with multiple domains (Apache,  FTP,  rsync,
447       Samba),  you can set a file context of public_content_t and public_con‐
448       tent_rw_t.  These context allow any of the above domains  to  read  the
449       content.   If  you want a particular domain to write to the public_con‐
450       tent_rw_t domain, you must set the appropriate boolean.
451
452       Allow abrt servers to read the /var/abrt directory by adding  the  pub‐
453       lic_content_t  file  type  to  the  directory and by restoring the file
454       type.
455
456       semanage fcontext -a -t public_content_t "/var/abrt(/.*)?"
457       restorecon -F -R -v /var/abrt
458
459       Allow abrt servers to read and write /var/abrt/incoming by  adding  the
460       public_content_rw_t  type  to  the  directory and by restoring the file
461       type.  You also need to turn on the abrt_anon_write boolean.
462
463       semanage fcontext -a -t public_content_rw_t "/var/abrt/incoming(/.*)?"
464       restorecon -F -R -v /var/abrt/incoming
465       setsebool -P abrt_anon_write 1
466
467
468       If you want to allow ABRT to modify public files used for  public  file
469       transfer services., you must turn on the abrt_anon_write boolean.
470
471       setsebool -P abrt_anon_write 1
472
473

COMMANDS

475       semanage  fcontext  can also be used to manipulate default file context
476       mappings.
477
478       semanage permissive can also be used to manipulate  whether  or  not  a
479       process type is permissive.
480
481       semanage  module can also be used to enable/disable/install/remove pol‐
482       icy modules.
