NAME

6       dccm_selinux - Security Enhanced Linux Policy for the dccm processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the dccm processes via flexible manda‐
10       tory access control.
11
12       The dccm processes execute with the dccm_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 dccm_t
19
20
21

ENTRYPOINTS

23       The dccm_t SELinux type can be entered via the dccm_exec_t file type.
24
25       The default entrypoint paths for the dccm_t domain are the following:
26
27       /usr/sbin/dccm, /usr/libexec/dcc/dccm
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       dccm policy is very flexible allowing users to setup  their  dccm  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for dccm:
40
41       dccm_t
42
43       Note:  semanage  permissive  -a  dccm_t can be used to make the process
44       type dccm_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.   dccm
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run dccm with the tightest access possible.
53

PORT TYPES

167       SELinux defines port types to represent TCP and UDP ports.
168
169       You can see the types associated with a port  by  using  the  following
170       command:
171
172       semanage port -l
173
174
175       Policy  governs  the  access  confined  processes  have to these ports.
176       SELinux dccm policy is very flexible allowing users to setup their dccm
177       processes in as secure a method as possible.
178
179       The following port types are defined for dccm:
180
181
182       dccm_port_t
183
184
185
186       Default Defined Ports:
187                 tcp 5679
188                 udp 5679
189

MANAGED FILES

191       The  SELinux process type dccm_t can manage files labeled with the fol‐
192       lowing file types.  The paths listed are the default  paths  for  these
193       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

251       SELinux requires files to have an extended attribute to define the file
252       type.
253
254       You can see the context of a file using the -Z option to ls
255
256       Policy governs the access  confined  processes  have  to  these  files.
257       SELinux dccm policy is very flexible allowing users to setup their dccm
258       processes in as secure a method as possible.
259
260       STANDARD FILE CONTEXT
261
262       SELinux defines the file context types for the dccm, if you  wanted  to
263       store  files  with  these types in a diffent paths, you need to execute
264       the semanage command  to  sepecify  alternate  labeling  and  then  use
265       restorecon to put the labels on disk.
266
267       semanage fcontext -a -t dccm_var_run_t '/srv/mydccm_content(/.*)?'
268       restorecon -R -v /srv/mydccm_content
269
270       Note:  SELinux  often  uses  regular expressions to specify labels that
271       match multiple files.
272
273       The following file types are defined for dccm:
274
275
276
277       dccm_exec_t
278
279       - Set files with the dccm_exec_t type, if you  want  to  transition  an
280       executable to the dccm_t domain.
281
282
283       Paths:
284            /usr/sbin/dccm, /usr/libexec/dcc/dccm
285
286
287       dccm_tmp_t
288
289       -  Set files with the dccm_tmp_t type, if you want to store dccm tempo‐
290       rary files in the /tmp directories.
291
292
293
294       dccm_var_run_t
295
296       - Set files with the dccm_var_run_t type, if you want to store the dccm
297       files under the /run or /var/run directory.
298
299
300
301       Note:  File context can be temporarily modified with the chcon command.
302       If you want to permanently change the file context you need to use  the
303       semanage fcontext command.  This will modify the SELinux labeling data‐
304       base.  You will need to use restorecon to apply the labels.
305
306

COMMANDS

308       semanage fcontext can also be used to manipulate default  file  context
309       mappings.
310
311       semanage  permissive  can  also  be used to manipulate whether or not a
312       process type is permissive.
313
314       semanage module can also be used to enable/disable/install/remove  pol‐
315       icy modules.
316
317       semanage port can also be used to manipulate the port definitions
318
319       semanage boolean can also be used to manipulate the booleans
320
321
322       system-config-selinux is a GUI tool available to customize SELinux pol‐
323       icy settings.
