NAME

6       rhgb_selinux - Security Enhanced Linux Policy for the rhgb processes
7

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

136       The  SELinux process type rhgb_t can manage files labeled with the fol‐
137       lowing file types.  The paths listed are the default  paths  for  these
138       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

205       SELinux requires files to have an extended attribute to define the file
206       type.
207
208       You can see the context of a file using the -Z option to ls
209
210       Policy governs the access  confined  processes  have  to  these  files.
211       SELinux rhgb policy is very flexible allowing users to setup their rhgb
212       processes in as secure a method as possible.
213
214       STANDARD FILE CONTEXT
215
216       SELinux defines the file context types for the rhgb, if you  wanted  to
217       store  files  with  these types in a diffent paths, you need to execute
218       the semanage command  to  sepecify  alternate  labeling  and  then  use
219       restorecon to put the labels on disk.
220
221       semanage fcontext -a -t rhgb_tmpfs_t '/srv/myrhgb_content(/.*)?'
222       restorecon -R -v /srv/myrhgb_content
223
224       Note:  SELinux  often  uses  regular expressions to specify labels that
225       match multiple files.
226
227       The following file types are defined for rhgb:
228
229
230
231       rhgb_exec_t
232
233       - Set files with the rhgb_exec_t type, if you  want  to  transition  an
234       executable to the rhgb_t domain.
235
236
237
238       rhgb_tmpfs_t
239
240       - Set files with the rhgb_tmpfs_t type, if you want to store rhgb files
241       on a tmpfs file system.
242
243
244
245       Note: File context can be temporarily modified with the chcon  command.
246       If  you want to permanently change the file context you need to use the
247       semanage fcontext command.  This will modify the SELinux labeling data‐
248       base.  You will need to use restorecon to apply the labels.
249
250

COMMANDS

252       semanage  fcontext  can also be used to manipulate default file context
253       mappings.
254
255       semanage permissive can also be used to manipulate  whether  or  not  a
256       process type is permissive.
257
258       semanage  module can also be used to enable/disable/install/remove pol‐
259       icy modules.
260
261       semanage boolean can also be used to manipulate the booleans
262
263
264       system-config-selinux is a GUI tool available to customize SELinux pol‐
265       icy settings.
