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 dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
82 If you want to allow confined applications to use nscd shared memory,
83 you must turn on the nscd_use_shm boolean. Enabled by default.
84
85 setsebool -P nscd_use_shm 1

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

144 SELinux requires files to have an extended attribute to define the file
145 type.
146
147 You can see the context of a file using the -Z option to ls
148
149 Policy governs the access confined processes have to these files.
150 SELinux watchdog policy is very flexible allowing users to setup their
151 watchdog processes in as secure a method as possible.
152
153 STANDARD FILE CONTEXT
154
155 SELinux defines the file context types for the watchdog, if you wanted
156 to store files with these types in a different paths, you need to exe‐
157 cute the semanage command to specify alternate labeling and then use
158 restorecon to put the labels on disk.
159
160 semanage fcontext -a -t watchdog_exec_t '/srv/watchdog/content(/.*)?'
161 restorecon -R -v /srv/mywatchdog_content
162
163 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165
166 The following file types are defined for watchdog:
167
168
169
170 watchdog_cache_t
171
172 - Set files with the watchdog_cache_t type, if you want to store the
173 files under the /var/cache directory.
174
175
176
177 watchdog_exec_t
178
179 - Set files with the watchdog_exec_t type, if you want to transition an
180 executable to the watchdog_t domain.
181
182
183
184 watchdog_initrc_exec_t
185
186 - Set files with the watchdog_initrc_exec_t type, if you want to tran‐
187 sition an executable to the watchdog_initrc_t domain.
188
189
190
191 watchdog_log_t
192
193 - Set files with the watchdog_log_t type, if you want to treat the data
194 as watchdog log data, usually stored under the /var/log directory.
195
196
197
198 watchdog_unconfined_exec_t
199
200 - Set files with the watchdog_unconfined_exec_t type, if you want to
201 transition an executable to the watchdog_unconfined_t domain.
202
203
204 Paths:
205 /etc/watchdog.d(/.*)?, /usr/libexec/watchdog/scripts(/.*)?
206
207
208 watchdog_var_run_t
209
210 - Set files with the watchdog_var_run_t type, if you want to store the
211 watchdog files under the /run or /var/run directory.
212
213
214
215 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
220
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224
225 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227
228 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230
231 semanage boolean can also be used to manipulate the booleans
232
233
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
