6 sanlock_selinux - Security Enhanced Linux Policy for the sanlock pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sanlock processes via flexible
11 mandatory access control.
12 The sanlock processes execute with the sanlock_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep sanlock_t
20
24 The sanlock_t SELinux type can be entered via the sanlock_exec_t file
25 type.
26 The default entrypoint paths for the sanlock_t domain are the follow‐
28 ing:
29 /usr/sbin/sanlock
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 sanlock policy is very flexible allowing users to setup their sanlock
40 processes in as secure a method as possible.
41 The following process types are defined for sanlock:
43 sanlock_t
45 Note: semanage permissive -a sanlock_t can be used to make the process
47 type sanlock_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. sanlock
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sanlock with the tightest access possi‐
56 ble.

168 you must turn on the nscd_use_shm boolean. Enabled by default.
169 setsebool -P nscd_use_shm 1

175 The SELinux process type sanlock_t can manage files labeled with the
176 following file types. The paths listed are the default paths for these
177 file types. Note the processes UID still need to have DAC permissions.

260 SELinux requires files to have an extended attribute to define the file
261 type.
262 You can see the context of a file using the -Z option to ls
264 Policy governs the access confined processes have to these files.
266 SELinux sanlock policy is very flexible allowing users to setup their
267 sanlock processes in as secure a method as possible.
268 STANDARD FILE CONTEXT
270 SELinux defines the file context types for the sanlock, if you wanted
272 to store files with these types in a diffent paths, you need to execute
273 the semanage command to sepecify alternate labeling and then use
274 restorecon to put the labels on disk.
275 semanage fcontext -a -t sanlock_var_run_t '/srv/mysanlock_con‐
277 tent(/.*)?'
278 restorecon -R -v /srv/mysanlock_content
279 Note: SELinux often uses regular expressions to specify labels that
281 match multiple files.
282 The following file types are defined for sanlock:
284 sanlock_exec_t
288 - Set files with the sanlock_exec_t type, if you want to transition an
290 executable to the sanlock_t domain.
291 sanlock_initrc_exec_t
295 - Set files with the sanlock_initrc_exec_t type, if you want to transi‐
297 tion an executable to the sanlock_initrc_t domain.
298 sanlock_log_t
302 - Set files with the sanlock_log_t type, if you want to treat the data
304 as sanlock log data, usually stored under the /var/log directory.
305 sanlock_var_run_t
309 - Set files with the sanlock_var_run_t type, if you want to store the
311 sanlock files under the /run or /var/run directory.
312 Note: File context can be temporarily modified with the chcon command.
316 If you want to permanently change the file context you need to use the
317 semanage fcontext command. This will modify the SELinux labeling data‐
318 base. You will need to use restorecon to apply the labels.
319
322 semanage fcontext can also be used to manipulate default file context
323 mappings.
324 semanage permissive can also be used to manipulate whether or not a
326 process type is permissive.
327 semanage module can also be used to enable/disable/install/remove pol‐
329 icy modules.
330 semanage boolean can also be used to manipulate the booleans
332 system-config-selinux is a GUI tool available to customize SELinux pol‐
335 icy settings.
