NAME

6       lttng_sessiond_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       lttng_sessiond processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the lttng_sessiond processes via flexi‐
11       ble mandatory access control.
12
13       The  lttng_sessiond processes execute with the lttng_sessiond_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep lttng_sessiond_t
20
21
22

ENTRYPOINTS

24       The  lttng_sessiond_t  SELinux  type  can be entered via the lttng_ses‐
25       siond_exec_t file type.
26
27       The default entrypoint paths for the lttng_sessiond_t  domain  are  the
28       following:
29
30       /usr/bin/lttng-sessiond
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       lttng_sessiond  policy  is  very flexible allowing users to setup their
40       lttng_sessiond processes in as secure a method as possible.
41
42       The following process types are defined for lttng_sessiond:
43
44       lttng_sessiond_t
45
46       Note: semanage permissive -a lttng_sessiond_t can be used to  make  the
47       process  type lttng_sessiond_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.
50
51

BOOLEANS

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

MANAGED FILES

171       The SELinux process type lttng_sessiond_t can manage files labeled with
172       the  following  file types.  The paths listed are the default paths for
173       these file types.  Note the processes UID still need to have  DAC  per‐
174       missions.

FILE CONTEXTS

220       SELinux requires files to have an extended attribute to define the file
221       type.
222
223       You can see the context of a file using the -Z option to ls
224
225       Policy governs the access  confined  processes  have  to  these  files.
226       SELinux  lttng_sessiond policy is very flexible allowing users to setup
227       their lttng_sessiond processes in as secure a method as possible.
228
229       STANDARD FILE CONTEXT
230
231       SELinux defines the file context types for the lttng_sessiond,  if  you
232       wanted  to store files with these types in a diffent paths, you need to
233       execute the semanage command to sepecify alternate  labeling  and  then
234       use restorecon to put the labels on disk.
235
236       semanage  fcontext  -a  -t  lttng_sessiond_var_run_t '/srv/mylttng_ses‐
237       siond_content(/.*)?'
238       restorecon -R -v /srv/mylttng_sessiond_content
239
240       Note: SELinux often uses regular expressions  to  specify  labels  that
241       match multiple files.
242
243       The following file types are defined for lttng_sessiond:
244
245
246
247       lttng_sessiond_exec_t
248
249       - Set files with the lttng_sessiond_exec_t type, if you want to transi‐
250       tion an executable to the lttng_sessiond_t domain.
251
252
253
254       lttng_sessiond_tmpfs_t
255
256       - Set files with the lttng_sessiond_tmpfs_t type, if you want to  store
257       lttng sessiond files on a tmpfs file system.
258
259
260
261       lttng_sessiond_unit_file_t
262
263       -  Set  files  with the lttng_sessiond_unit_file_t type, if you want to
264       treat the files as lttng sessiond unit content.
265
266
267
268       lttng_sessiond_var_run_t
269
270       - Set files with the lttng_sessiond_var_run_t  type,  if  you  want  to
271       store the lttng sessiond files under the /run or /var/run directory.
272
273
274
275       Note:  File context can be temporarily modified with the chcon command.
276       If you want to permanently change the file context you need to use  the
277       semanage fcontext command.  This will modify the SELinux labeling data‐
278       base.  You will need to use restorecon to apply the labels.
279
280

COMMANDS

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