NAME

6       xfs_selinux - Security Enhanced Linux Policy for the xfs processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the xfs processes via flexible manda‐
10       tory access control.
11
12       The xfs processes execute with the xfs_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep xfs_t
19
20
21

ENTRYPOINTS

23       The xfs_t SELinux type can be entered via the xfs_exec_t file type.
24
25       The default entrypoint paths for the xfs_t domain are the following:
26
27       /usr/bin/xfs, /usr/bin/xfstt,  /usr/X11R6/bin/xfs,  /usr/X11R6/bin/xfs-
28       xtt
29

PROCESS TYPES

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

BOOLEANS

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

PORT TYPES

150       SELinux defines port types to represent TCP and UDP ports.
151
152       You  can  see  the  types associated with a port by using the following
153       command:
154
155       semanage port -l
156
157
158       Policy governs the access  confined  processes  have  to  these  ports.
159       SELinux  xfs  policy is very flexible allowing users to setup their xfs
160       processes in as secure a method as possible.
161
162       The following port types are defined for xfs:
163
164
165       xfs_port_t
166
167
168
169       Default Defined Ports:
170                 tcp 7100
171

MANAGED FILES

173       The SELinux process type xfs_t can manage files labeled with  the  fol‐
174       lowing  file  types.   The paths listed are the default paths for these
175       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

239       SELinux requires files to have an extended attribute to define the file
240       type.
241
242       You can see the context of a file using the -Z option to ls
243
244       Policy  governs  the  access  confined  processes  have to these files.
245       SELinux xfs policy is very flexible allowing users to setup  their  xfs
246       processes in as secure a method as possible.
247
248       STANDARD FILE CONTEXT
249
250       SELinux  defines  the  file context types for the xfs, if you wanted to
251       store files with these types in a diffent paths, you  need  to  execute
252       the  semanage  command  to  sepecify  alternate  labeling  and then use
253       restorecon to put the labels on disk.
254
255       semanage fcontext -a -t xfs_var_run_t '/srv/myxfs_content(/.*)?'
256       restorecon -R -v /srv/myxfs_content
257
258       Note: SELinux often uses regular expressions  to  specify  labels  that
259       match multiple files.
260
261       The following file types are defined for xfs:
262
263
264
265       xfs_exec_t
266
267       - Set files with the xfs_exec_t type, if you want to transition an exe‐
268       cutable to the xfs_t domain.
269
270
271       Paths:
272            /usr/bin/xfs,         /usr/bin/xfstt,          /usr/X11R6/bin/xfs,
273            /usr/X11R6/bin/xfs-xtt
274
275
276       xfs_tmp_t
277
278       - Set files with the xfs_tmp_t type, if you want to store xfs temporary
279       files in the /tmp directories.
280
281
282
283       xfs_var_run_t
284
285       - Set files with the xfs_var_run_t type, if you want to store  the  xfs
286       files under the /run or /var/run directory.
287
288
289
290       Note:  File context can be temporarily modified with the chcon command.
291       If you want to permanently change the file context you need to use  the
292       semanage fcontext command.  This will modify the SELinux labeling data‐
293       base.  You will need to use restorecon to apply the labels.
294
295

COMMANDS

297       semanage fcontext can also be used to manipulate default  file  context
298       mappings.
299
300       semanage  permissive  can  also  be used to manipulate whether or not a
301       process type is permissive.
302
303       semanage module can also be used to enable/disable/install/remove  pol‐
304       icy modules.
305
306       semanage port can also be used to manipulate the port definitions
307
308       semanage boolean can also be used to manipulate the booleans
309
310
311       system-config-selinux is a GUI tool available to customize SELinux pol‐
312       icy settings.
