NAME

6       opensm_selinux  -  Security  Enhanced  Linux Policy for the opensm pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  opensm  processes  via  flexible
11       mandatory access control.
12
13       The  opensm  processes  execute with the opensm_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 opensm_t
20
21
22

ENTRYPOINTS

24       The  opensm_t  SELinux  type  can be entered via the opensm_exec_t file
25       type.
26
27       The default entrypoint paths for the opensm_t domain are the following:
28
29       /usr/libexec/opensm-launch
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       opensm policy is very flexible allowing users  to  setup  their  opensm
39       processes in as secure a method as possible.
40
41       The following process types are defined for opensm:
42
43       opensm_t
44
45       Note:  semanage  permissive -a opensm_t can be used to make the process
46       type opensm_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.   opensm
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run opensm with the tightest access possible.

MANAGED FILES

169       The SELinux process type opensm_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

218       SELinux requires files to have an extended attribute to define the file
219       type.
220
221       You can see the context of a file using the -Z option to ls
222
223       Policy  governs  the  access  confined  processes  have to these files.
224       SELinux opensm policy is very flexible allowing users  to  setup  their
225       opensm processes in as secure a method as possible.
226
227       STANDARD FILE CONTEXT
228
229       SELinux defines the file context types for the opensm, if you wanted to
230       store files with these types in a diffent paths, you  need  to  execute
231       the  semanage  command  to  sepecify  alternate  labeling  and then use
232       restorecon to put the labels on disk.
233
234       semanage  fcontext   -a   -t   opensm_unit_file_t   '/srv/myopensm_con‐
235       tent(/.*)?'
236       restorecon -R -v /srv/myopensm_content
237
238       Note:  SELinux  often  uses  regular expressions to specify labels that
239       match multiple files.
240
241       The following file types are defined for opensm:
242
243
244
245       opensm_cache_t
246
247       - Set files with the opensm_cache_t type, if  you  want  to  store  the
248       files under the /var/cache directory.
249
250
251
252       opensm_exec_t
253
254       -  Set  files with the opensm_exec_t type, if you want to transition an
255       executable to the opensm_t domain.
256
257
258
259       opensm_log_t
260
261       - Set files with the opensm_log_t type, if you want to treat  the  data
262       as opensm log data, usually stored under the /var/log directory.
263
264
265
266       opensm_unit_file_t
267
268       -  Set files with the opensm_unit_file_t type, if you want to treat the
269       files as opensm unit content.
270
271
272
273       Note: File context can be temporarily modified with the chcon  command.
274       If  you want to permanently change the file context you need to use the
275       semanage fcontext command.  This will modify the SELinux labeling data‐
276       base.  You will need to use restorecon to apply the labels.
277
278

COMMANDS

280       semanage  fcontext  can also be used to manipulate default file context
281       mappings.
282
283       semanage permissive can also be used to manipulate  whether  or  not  a
284       process type is permissive.
285
286       semanage  module can also be used to enable/disable/install/remove pol‐
287       icy modules.
288
289       semanage boolean can also be used to manipulate the booleans
290
291
292       system-config-selinux is a GUI tool available to customize SELinux pol‐
293       icy settings.
