7 cesses
8
10 Security-Enhanced Linux secures the watchdog processes via flexible
11 mandatory access control.
12
13 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
17 For example:
18
19 ps -eZ | grep watchdog_t
20
21
22
24 The watchdog_t SELinux type can be entered via the watchdog_exec_t file
25 type.
26
27 The default entrypoint paths for the watchdog_t domain are the follow‐
28 ing:
29
30 /usr/sbin/watchdog
31
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 watchdog policy is very flexible allowing users to setup their watchdog
40 processes in as secure a method as possible.
41
42 The following process types are defined for watchdog:
43
44 watchdog_t, watchdog_unconfined_t
45
46 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
51
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
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
74 If you want to allow confined applications to use nscd shared memory,
75 you must turn on the nscd_use_shm boolean. Enabled by default.
76
77 setsebool -P nscd_use_shm 1
78

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

165 SELinux requires files to have an extended attribute to define the file
166 type.
167
168 You can see the context of a file using the -Z option to ls
169
170 Policy governs the access confined processes have to these files.
171 SELinux watchdog policy is very flexible allowing users to setup their
172 watchdog processes in as secure a method as possible.
173
174 STANDARD FILE CONTEXT
175
176 SELinux defines the file context types for the watchdog, if you wanted
177 to store files with these types in a diffent paths, you need to execute
178 the semanage command to sepecify alternate labeling and then use
179 restorecon to put the labels on disk.
180
181 semanage fcontext -a -t watchdog_var_run_t '/srv/mywatchdog_con‐
182 tent(/.*)?'
183 restorecon -R -v /srv/mywatchdog_content
184
185 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187
188 The following file types are defined for watchdog:
189
190
191
192 watchdog_cache_t
193
194 - Set files with the watchdog_cache_t type, if you want to store the
195 files under the /var/cache directory.
196
197
198
199 watchdog_exec_t
200
201 - Set files with the watchdog_exec_t type, if you want to transition an
202 executable to the watchdog_t domain.
203
204
205
206 watchdog_initrc_exec_t
207
208 - Set files with the watchdog_initrc_exec_t type, if you want to tran‐
209 sition an executable to the watchdog_initrc_t domain.
210
211
212
213 watchdog_log_t
214
215 - Set files with the watchdog_log_t type, if you want to treat the data
216 as watchdog log data, usually stored under the /var/log directory.
217
218
219
220 watchdog_unconfined_exec_t
221
222 - Set files with the watchdog_unconfined_exec_t type, if you want to
223 transition an executable to the watchdog_unconfined_t domain.
224
225
226 Paths:
227 /etc/watchdog.d(/.*)?, /usr/libexec/watchdog/scripts(/.*)?
228
229
230 watchdog_var_run_t
231
232 - Set files with the watchdog_var_run_t type, if you want to store the
233 watchdog files under the /run or /var/run directory.
234
235
236
237 Note: File context can be temporarily modified with the chcon command.
238 If you want to permanently change the file context you need to use the
239 semanage fcontext command. This will modify the SELinux labeling data‐
240 base. You will need to use restorecon to apply the labels.
241
242
244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246
247 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249
250 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252
253 semanage boolean can also be used to manipulate the booleans
254
255
256 system-config-selinux is a GUI tool available to customize SELinux pol‐
257 icy settings.
