NAME

6       rhnsd_selinux - Security Enhanced Linux Policy for the rhnsd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The rhnsd_t SELinux type can be entered via the rhnsd_exec_t file type.
24
25       The default entrypoint paths for the rhnsd_t domain are the following:
26
27       /usr/sbin/rhnsd
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       rhnsd policy is very flexible allowing users to setup their rhnsd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for rhnsd:
40
41       rhnsd_t
42
43       Note:  semanage  permissive  -a rhnsd_t can be used to make the process
44       type rhnsd_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.   rhnsd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run rhnsd with the tightest access possible.
53
54
55
56       If you want to allow all daemons to write corefiles to /, you must turn

MANAGED FILES

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

FILE CONTEXTS

187       SELinux requires files to have an extended attribute to define the file
188       type.
189
190       You can see the context of a file using the -Z option to ls
191
192       Policy governs the access  confined  processes  have  to  these  files.
193       SELinux  rhnsd  policy  is  very flexible allowing users to setup their
194       rhnsd processes in as secure a method as possible.
195
196       STANDARD FILE CONTEXT
197
198       SELinux defines the file context types for the rhnsd, if you wanted  to
199       store  files  with  these types in a diffent paths, you need to execute
200       the semanage command  to  sepecify  alternate  labeling  and  then  use
201       restorecon to put the labels on disk.
202
203       semanage fcontext -a -t rhnsd_var_run_t '/srv/myrhnsd_content(/.*)?'
204       restorecon -R -v /srv/myrhnsd_content
205
206       Note:  SELinux  often  uses  regular expressions to specify labels that
207       match multiple files.
208
209       The following file types are defined for rhnsd:
210
211
212
213       rhnsd_conf_t
214
215       - Set files with the rhnsd_conf_t type, if you want to treat the  files
216       as rhnsd configuration data, usually stored under the /etc directory.
217
218
219
220       rhnsd_exec_t
221
222       -  Set  files  with the rhnsd_exec_t type, if you want to transition an
223       executable to the rhnsd_t domain.
224
225
226
227       rhnsd_initrc_exec_t
228
229       - Set files with the rhnsd_initrc_exec_t type, if you want  to  transi‐
230       tion an executable to the rhnsd_initrc_t domain.
231
232
233
234       rhnsd_unit_file_t
235
236       -  Set  files with the rhnsd_unit_file_t type, if you want to treat the
237       files as rhnsd unit content.
238
239
240
241       rhnsd_var_run_t
242
243       - Set files with the rhnsd_var_run_t type, if you  want  to  store  the
244       rhnsd files under the /run or /var/run directory.
245
246
247
248       Note:  File context can be temporarily modified with the chcon command.
249       If you want to permanently change the file context you need to use  the
250       semanage fcontext command.  This will modify the SELinux labeling data‐
251       base.  You will need to use restorecon to apply the labels.
252
253

COMMANDS

255       semanage fcontext can also be used to manipulate default  file  context
256       mappings.
257
258       semanage  permissive  can  also  be used to manipulate whether or not a
259       process type is permissive.
260
261       semanage module can also be used to enable/disable/install/remove  pol‐
262       icy modules.
263
264       semanage boolean can also be used to manipulate the booleans
265
266
267       system-config-selinux is a GUI tool available to customize SELinux pol‐
268       icy settings.
