6 watchdog_selinux - Security Enhanced Linux Policy for the watchdog pro‐
7 cesses
8
10 Security-Enhanced Linux secures the watchdog processes via flexible
11 mandatory access control.
12 The watchdog processes execute with the watchdog_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 For example:
18 ps -eZ | grep watchdog_t
20
24 The watchdog_t SELinux type can be entered via the watchdog_exec_t file
25 type.
26 The default entrypoint paths for the watchdog_t domain are the follow‐
28 ing:
29 /usr/sbin/watchdog
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 watchdog policy is very flexible allowing users to setup their watchdog
40 processes in as secure a method as possible.
41 The following process types are defined for watchdog:
43 watchdog_t, watchdog_unconfined_t
45 Note: semanage permissive -a watchdog_t can be used to make the process
47 type watchdog_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. watch‐
54 dog policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run watchdog with the tightest access
56 possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the daemons_dump_core boolean. Disabled by default.

156 The SELinux process type watchdog_t can manage files labeled with the
157 following file types. The paths listed are the default paths for these
158 file types. Note the processes UID still need to have DAC permissions.

239 SELinux requires files to have an extended attribute to define the file
240 type.
241 You can see the context of a file using the -Z option to ls
243 Policy governs the access confined processes have to these files.
245 SELinux watchdog policy is very flexible allowing users to setup their
246 watchdog processes in as secure a method as possible.
247 STANDARD FILE CONTEXT
249 SELinux defines the file context types for the watchdog, if you wanted
251 to 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 semanage fcontext -a -t watchdog_var_run_t '/srv/mywatchdog_con‐
256 tent(/.*)?'
257 restorecon -R -v /srv/mywatchdog_content
258 Note: SELinux often uses regular expressions to specify labels that
260 match multiple files.
261 The following file types are defined for watchdog:
263 watchdog_cache_t
267 - Set files with the watchdog_cache_t type, if you want to store the
269 files under the /var/cache directory.
270 watchdog_exec_t
274 - Set files with the watchdog_exec_t type, if you want to transition an
276 executable to the watchdog_t domain.
277 watchdog_initrc_exec_t
281 - Set files with the watchdog_initrc_exec_t type, if you want to tran‐
283 sition an executable to the watchdog_initrc_t domain.
284 watchdog_log_t
288 - Set files with the watchdog_log_t type, if you want to treat the data
290 as watchdog log data, usually stored under the /var/log directory.
291 watchdog_unconfined_exec_t
295 - Set files with the watchdog_unconfined_exec_t type, if you want to
297 transition an executable to the watchdog_unconfined_t domain.
298 Paths:
301 /etc/watchdog.d(/.*)?, /usr/libexec/watchdog/scripts(/.*)?
302 watchdog_var_run_t
305 - Set files with the watchdog_var_run_t type, if you want to store the
307 watchdog files under the /run or /var/run directory.
308 Note: File context can be temporarily modified with the chcon command.
312 If you want to permanently change the file context you need to use the
313 semanage fcontext command. This will modify the SELinux labeling data‐
314 base. You will need to use restorecon to apply the labels.
315
318 semanage fcontext can also be used to manipulate default file context
319 mappings.
320 semanage permissive can also be used to manipulate whether or not a
322 process type is permissive.
323 semanage module can also be used to enable/disable/install/remove pol‐
325 icy modules.
326 semanage boolean can also be used to manipulate the booleans
328 system-config-selinux is a GUI tool available to customize SELinux pol‐
331 icy settings.
