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 domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71 If you want to allow confined applications to use nscd shared memory,
75 you must turn on the nscd_use_shm boolean. Disabled by default.
76 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.

135 SELinux requires files to have an extended attribute to define the file
136 type.
137 You can see the context of a file using the -Z option to ls
139 Policy governs the access confined processes have to these files.
141 SELinux watchdog policy is very flexible allowing users to setup their
142 watchdog processes in as secure a method as possible.
143 STANDARD FILE CONTEXT
145 SELinux defines the file context types for the watchdog, if you wanted
147 to store files with these types in a diffent paths, you need to execute
148 the semanage command to sepecify alternate labeling and then use
149 restorecon to put the labels on disk.
150 semanage fcontext -a -t watchdog_var_run_t '/srv/mywatchdog_con‐
152 tent(/.*)?'
153 restorecon -R -v /srv/mywatchdog_content
154 Note: SELinux often uses regular expressions to specify labels that
156 match multiple files.
157 The following file types are defined for watchdog:
159 watchdog_cache_t
163 - Set files with the watchdog_cache_t type, if you want to store the
165 files under the /var/cache directory.
166 watchdog_exec_t
170 - Set files with the watchdog_exec_t type, if you want to transition an
172 executable to the watchdog_t domain.
173 watchdog_initrc_exec_t
177 - Set files with the watchdog_initrc_exec_t type, if you want to tran‐
179 sition an executable to the watchdog_initrc_t domain.
180 watchdog_log_t
184 - Set files with the watchdog_log_t type, if you want to treat the data
186 as watchdog log data, usually stored under the /var/log directory.
187 watchdog_unconfined_exec_t
191 - Set files with the watchdog_unconfined_exec_t type, if you want to
193 transition an executable to the watchdog_unconfined_t domain.
194 Paths:
197 /etc/watchdog.d(/.*)?, /usr/libexec/watchdog/scripts(/.*)?
198 watchdog_var_run_t
201 - Set files with the watchdog_var_run_t type, if you want to store the
203 watchdog files under the /run or /var/run directory.
204 Note: File context can be temporarily modified with the chcon command.
208 If you want to permanently change the file context you need to use the
209 semanage fcontext command. This will modify the SELinux labeling data‐
210 base. You will need to use restorecon to apply the labels.
211
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage boolean can also be used to manipulate the booleans
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
227 icy settings.
