NAME

6       rtas_errd_selinux  -  Security  Enhanced Linux Policy for the rtas_errd
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  rtas_errd_t  SELinux  type  can  be  entered  via  the  file_type,
25       rtas_errd_exec_t,     unlabeled_t,     proc_type,      filesystem_type,
26       mtrr_device_t, sysctl_type file types.
27
28       The default entrypoint paths for the rtas_errd_t domain are the follow‐
29       ing:
30
31       all files on the system, /usr/sbin/rtas_errd, /dev/cpu/mtrr
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       rtas_errd policy  is  very  flexible  allowing  users  to  setup  their
41       rtas_errd processes in as secure a method as possible.
42
43       The following process types are defined for rtas_errd:
44
45       rtas_errd_t
46
47       Note:  semanage  permissive  -a  rtas_errd_t  can  be  used to make the
48       process type rtas_errd_t permissive. SELinux does not  deny  access  to
49       permissive  process  types,  but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

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

91       executable.   Doing  this  is  a  really bad idea. Probably indicates a
92       badly coded executable, but could indicate an attack.  This  executable

118       cutable.  This should never, ever be necessary.  Probably  indicates  a
119       badly  coded  executable, but could indicate an attack. This executable
120       should be reported in bugzilla), you must turn on  the  allow_execstack
121       boolean. Enabled by default.

MANAGED FILES

215       The SELinux process type rtas_errd_t can manage files labeled with  the
216       following file types.  The paths listed are the default paths for these
217       file types.  Note the processes UID still need to have DAC permissions.
218
219       file_type
220
221            all files on the system
222
223

FILE CONTEXTS

225       SELinux requires files to have an extended attribute to define the file
226       type.
227
228       You can see the context of a file using the -Z option to ls
229
230       Policy  governs  the  access  confined  processes  have to these files.
231       SELinux rtas_errd policy is very flexible allowing users to setup their
232       rtas_errd processes in as secure a method as possible.
233
234       STANDARD FILE CONTEXT
235
236       SELinux defines the file context types for the rtas_errd, if you wanted
237       to store files with these types in a diffent paths, you need to execute
238       the  semanage  command  to  sepecify  alternate  labeling  and then use
239       restorecon to put the labels on disk.
240
241       semanage  fcontext  -a  -t  rtas_errd_var_run_t  '/srv/myrtas_errd_con‐
242       tent(/.*)?'
243       restorecon -R -v /srv/myrtas_errd_content
244
245       Note:  SELinux  often  uses  regular expressions to specify labels that
246       match multiple files.
247
248       The following file types are defined for rtas_errd:
249
250
251
252       rtas_errd_exec_t
253
254       - Set files with the rtas_errd_exec_t type, if you want  to  transition
255       an executable to the rtas_errd_t domain.
256
257
258
259       rtas_errd_initrc_exec_t
260
261       - Set files with the rtas_errd_initrc_exec_t type, if you want to tran‐
262       sition an executable to the rtas_errd_initrc_t domain.
263
264
265
266       rtas_errd_log_t
267
268       - Set files with the rtas_errd_log_t type, if you  want  to  treat  the
269       data  as  rtas  errd log data, usually stored under the /var/log direc‐
270       tory.
271
272
273       Paths:
274            /var/log/platform.*, /var/log/rtas_errd.*, /var/log/epow_status.*
275
276
277       rtas_errd_tmp_t
278
279       - Set files with the rtas_errd_tmp_t type, if you want  to  store  rtas
280       errd temporary files in the /tmp directories.
281
282
283
284       rtas_errd_tmpfs_t
285
286       -  Set files with the rtas_errd_tmpfs_t type, if you want to store rtas
287       errd files on a tmpfs file system.
288
289
290
291       rtas_errd_var_lock_t
292
293       - Set files with the rtas_errd_var_lock_t type, if you  want  to  treat
294       the files as rtas errd var lock data, stored under the /var/lock direc‐
295       tory
296
297
298       Paths:
299            /var/lock/.*librtas, /var/lock/subsys/rtas_errd
300
301
302       rtas_errd_var_run_t
303
304       - Set files with the rtas_errd_var_run_t type, if you want to store the
305       rtas errd files under the /run or /var/run directory.
306
307
308
309       Note:  File context can be temporarily modified with the chcon command.
310       If you want to permanently change the file context you need to use  the
311       semanage fcontext command.  This will modify the SELinux labeling data‐
312       base.  You will need to use restorecon to apply the labels.
313
314

COMMANDS

316       semanage fcontext can also be used to manipulate default  file  context
317       mappings.
318
319       semanage  permissive  can  also  be used to manipulate whether or not a
320       process type is permissive.
321
322       semanage module can also be used to enable/disable/install/remove  pol‐
323       icy modules.
324
325       semanage boolean can also be used to manipulate the booleans
326
327
328       system-config-selinux is a GUI tool available to customize SELinux pol‐
329       icy settings.
