NAME

6       ganesha_selinux  -  Security Enhanced Linux Policy for the ganesha pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  ganesha  processes  via  flexible
11       mandatory access control.
12
13       The  ganesha processes execute with the ganesha_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 ganesha_t
20
21
22

ENTRYPOINTS

24       The  ganesha_t  SELinux type can be entered via the ganesha_exec_t file
25       type.
26
27       The default entrypoint paths for the ganesha_t domain are  the  follow‐
28       ing:
29
30       /usr/bin/ganesha.nfsd
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       ganesha  policy  is very flexible allowing users to setup their ganesha
40       processes in as secure a method as possible.
41
42       The following process types are defined for ganesha:
43
44       ganesha_t
45
46       Note: semanage permissive -a ganesha_t can be used to make the  process
47       type  ganesha_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.  ganesha
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run ganesha with the tightest access possi‐
56       ble.

MANAGED FILES

178       The  SELinux  process  type ganesha_t can manage files labeled with the
179       following file types.  The paths listed are the default paths for these
180       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

242       SELinux requires files to have an extended attribute to define the file
243       type.
244
245       You can see the context of a file using the -Z option to ls
246
247       Policy governs the access  confined  processes  have  to  these  files.
248       SELinux  ganesha  policy is very flexible allowing users to setup their
249       ganesha processes in as secure a method as possible.
250
251       STANDARD FILE CONTEXT
252
253       SELinux defines the file context types for the ganesha, if  you  wanted
254       to store files with these types in a diffent paths, you need to execute
255       the semanage command  to  sepecify  alternate  labeling  and  then  use
256       restorecon to put the labels on disk.
257
258       semanage   fcontext   -a   -t   ganesha_var_run_t  '/srv/myganesha_con‐
259       tent(/.*)?'
260       restorecon -R -v /srv/myganesha_content
261
262       Note: SELinux often uses regular expressions  to  specify  labels  that
263       match multiple files.
264
265       The following file types are defined for ganesha:
266
267
268
269       ganesha_exec_t
270
271       -  Set files with the ganesha_exec_t type, if you want to transition an
272       executable to the ganesha_t domain.
273
274
275
276       ganesha_tmp_t
277
278       - Set files with the ganesha_tmp_t type, if you want to  store  ganesha
279       temporary files in the /tmp directories.
280
281
282
283       ganesha_unit_file_t
284
285       - Set files with the ganesha_unit_file_t type, if you want to treat the
286       files as ganesha unit content.
287
288
289       Paths:
290            /usr/lib/systemd/system/nfs-ganesha.*e,      /usr/lib/systemd/sys‐
291            tem/nfs-ganesha-lock.*,   /usr/lib/systemd/system/nfs-ganesha-con‐
292            fig.*
293
294
295       ganesha_var_log_t
296
297       - Set files with the ganesha_var_log_t type, if you want to  treat  the
298       data  as ganesha var log data, usually stored under the /var/log direc‐
299       tory.
300
301
302       Paths:
303            /var/log/ganesha.log.*, /var/log/ganesha-gfapi.log.*
304
305
306       ganesha_var_run_t
307
308       - Set files with the ganesha_var_run_t type, if you want to  store  the
309       ganesha files under the /run or /var/run directory.
310
311
312
313       Note:  File context can be temporarily modified with the chcon command.
314       If you want to permanently change the file context you need to use  the
315       semanage fcontext command.  This will modify the SELinux labeling data‐
316       base.  You will need to use restorecon to apply the labels.
317
318

COMMANDS

320       semanage fcontext can also be used to manipulate default  file  context
321       mappings.
322
323       semanage  permissive  can  also  be used to manipulate whether or not a
324       process type is permissive.
325
326       semanage module can also be used to enable/disable/install/remove  pol‐
327       icy modules.
328
329       semanage boolean can also be used to manipulate the booleans
330
331
332       system-config-selinux is a GUI tool available to customize SELinux pol‐
333       icy settings.
