NAME

6       dccifd_selinux  -  Security  Enhanced  Linux Policy for the dccifd pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  dccifd_t  SELinux  type  can be entered via the dccifd_exec_t file
25       type.
26
27       The default entrypoint paths for the dccifd_t domain are the following:
28
29       /usr/sbin/dccifd,   /usr/libexec/dcc/dccifd,    /usr/libexec/dcc/start-
30       dccifd
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       dccifd  policy  is  very  flexible allowing users to setup their dccifd
40       processes in as secure a method as possible.
41
42       The following process types are defined for dccifd:
43
44       dccifd_t
45
46       Note: semanage permissive -a dccifd_t can be used to make  the  process
47       type  dccifd_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.  dccifd
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate the policy and run dccifd with the tightest access possible.

FILE CONTEXTS

232       SELinux requires files to have an extended attribute to define the file
233       type.
234
235       You can see the context of a file using the -Z option to ls
236
237       Policy governs the access  confined  processes  have  to  these  files.
238       SELinux  dccifd  policy  is very flexible allowing users to setup their
239       dccifd processes in as secure a method as possible.
240
241       STANDARD FILE CONTEXT
242
243       SELinux defines the file context types for the dccifd, if you wanted to
244       store  files  with  these types in a diffent paths, you need to execute
245       the semanage command  to  sepecify  alternate  labeling  and  then  use
246       restorecon to put the labels on disk.
247
248       semanage fcontext -a -t dccifd_var_run_t '/srv/mydccifd_content(/.*)?'
249       restorecon -R -v /srv/mydccifd_content
250
251       Note:  SELinux  often  uses  regular expressions to specify labels that
252       match multiple files.
253
254       The following file types are defined for dccifd:
255
256
257
258       dccifd_exec_t
259
260       - Set files with the dccifd_exec_t type, if you want to  transition  an
261       executable to the dccifd_t domain.
262
263
264       Paths:
265            /usr/sbin/dccifd, /usr/libexec/dcc/dccifd, /usr/libexec/dcc/start-
266            dccifd
267
268
269       dccifd_tmp_t
270
271       - Set files with the dccifd_tmp_t type, if you  want  to  store  dccifd
272       temporary files in the /tmp directories.
273
274
275
276       dccifd_var_run_t
277
278       -  Set  files  with the dccifd_var_run_t type, if you want to store the
279       dccifd files under the /run or /var/run directory.
280
281
282       Paths:
283            /etc/dcc/dccifd, /var/run/dcc/dccifd
284
285
286       Note: File context can be temporarily modified with the chcon  command.
287       If  you want to permanently change the file context you need to use the
288       semanage fcontext command.  This will modify the SELinux labeling data‐
289       base.  You will need to use restorecon to apply the labels.
290
291

COMMANDS

293       semanage  fcontext  can also be used to manipulate default file context
294       mappings.
295
296       semanage permissive can also be used to manipulate  whether  or  not  a
297       process type is permissive.
298
299       semanage  module can also be used to enable/disable/install/remove pol‐
300       icy modules.
301
302       semanage boolean can also be used to manipulate the booleans
303
304
305       system-config-selinux is a GUI tool available to customize SELinux pol‐
306       icy settings.
