NAME

6       ninfod_selinux  -  Security  Enhanced  Linux Policy for the ninfod pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  ninfod  processes  via  flexible
11       mandatory access control.
12
13       The  ninfod  processes  execute with the ninfod_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 ninfod_t
20
21
22

ENTRYPOINTS

24       The  ninfod_t  SELinux  type  can be entered via the ninfod_exec_t file
25       type.
26
27       The default entrypoint paths for the ninfod_t domain are the following:
28
29       /usr/sbin/ninfod
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       ninfod policy is very flexible allowing users  to  setup  their  ninfod
39       processes in as secure a method as possible.
40
41       The following process types are defined for ninfod:
42
43       ninfod_t
44
45       Note:  semanage  permissive -a ninfod_t can be used to make the process
46       type ninfod_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

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

MANAGED FILES

169       The SELinux process type ninfod_t can manage  files  labeled  with  the
170       following file types.  The paths listed are the default paths for these
171       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

214       SELinux requires files to have an extended attribute to define the file
215       type.
216
217       You can see the context of a file using the -Z option to ls
218
219       Policy  governs  the  access  confined  processes  have to these files.
220       SELinux ninfod policy is very flexible allowing users  to  setup  their
221       ninfod processes in as secure a method as possible.
222
223       STANDARD FILE CONTEXT
224
225       SELinux defines the file context types for the ninfod, if you wanted to
226       store files with these types in a diffent paths, you  need  to  execute
227       the  semanage  command  to  sepecify  alternate  labeling  and then use
228       restorecon to put the labels on disk.
229
230       semanage  fcontext   -a   -t   ninfod_unit_file_t   '/srv/myninfod_con‐
231       tent(/.*)?'
232       restorecon -R -v /srv/myninfod_content
233
234       Note:  SELinux  often  uses  regular expressions to specify labels that
235       match multiple files.
236
237       The following file types are defined for ninfod:
238
239
240
241       ninfod_exec_t
242
243       - Set files with the ninfod_exec_t type, if you want to  transition  an
244       executable to the ninfod_t domain.
245
246
247
248       ninfod_run_t
249
250       -  Set files with the ninfod_run_t type, if you want to treat the files
251       as ninfod run data.
252
253
254
255       ninfod_unit_file_t
256
257       - Set files with the ninfod_unit_file_t type, if you want to treat  the
258       files as ninfod unit content.
259
260
261
262       Note:  File context can be temporarily modified with the chcon command.
263       If you want to permanently change the file context you need to use  the
264       semanage fcontext command.  This will modify the SELinux labeling data‐
265       base.  You will need to use restorecon to apply the labels.
266
267

COMMANDS

269       semanage fcontext can also be used to manipulate default  file  context
270       mappings.
271
272       semanage  permissive  can  also  be used to manipulate whether or not a
273       process type is permissive.
274
275       semanage module can also be used to enable/disable/install/remove  pol‐
276       icy modules.
277
278       semanage boolean can also be used to manipulate the booleans
279
280
281       system-config-selinux is a GUI tool available to customize SELinux pol‐
282       icy settings.
