6 gfs_controld_selinux - Security Enhanced Linux Policy for the gfs_con‐
7 trold processes
8
10 Security-Enhanced Linux secures the gfs_controld processes via flexible
11 mandatory access control.
12 The gfs_controld processes execute with the gfs_controld_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep gfs_controld_t
20
24 The gfs_controld_t SELinux type can be entered via the gfs_con‐
25 trold_exec_t file type.
26 The default entrypoint paths for the gfs_controld_t domain are the fol‐
28 lowing:
29 /usr/sbin/gfs_controld
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 gfs_controld policy is very flexible allowing users to setup their
40 gfs_controld processes in as secure a method as possible.
41 The following process types are defined for gfs_controld:
43 gfs_controld_t
45 Note: semanage permissive -a gfs_controld_t can be used to make the
47 process type gfs_controld_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 gfs_controld policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run gfs_controld with the tight‐
56 est access possible.

162 The SELinux process type gfs_controld_t can manage files labeled with
163 the following file types. The paths listed are the default paths for
164 these file types. Note the processes UID still need to have DAC per‐
165 missions.

240 SELinux requires files to have an extended attribute to define the file
241 type.
242 You can see the context of a file using the -Z option to ls
244 Policy governs the access confined processes have to these files.
246 SELinux gfs_controld policy is very flexible allowing users to setup
247 their gfs_controld processes in as secure a method as possible.
248 STANDARD FILE CONTEXT
250 SELinux defines the file context types for the gfs_controld, if you
252 wanted to store files with these types in a diffent paths, you need to
253 execute the semanage command to sepecify alternate labeling and then
254 use restorecon to put the labels on disk.
255 semanage fcontext -a -t gfs_controld_var_run_t '/srv/mygfs_con‐
257 trold_content(/.*)?'
258 restorecon -R -v /srv/mygfs_controld_content
259 Note: SELinux often uses regular expressions to specify labels that
261 match multiple files.
262 The following file types are defined for gfs_controld:
264 gfs_controld_exec_t
268 - Set files with the gfs_controld_exec_t type, if you want to transi‐
270 tion an executable to the gfs_controld_t domain.
271 gfs_controld_tmpfs_t
275 - Set files with the gfs_controld_tmpfs_t type, if you want to store
277 gfs controld files on a tmpfs file system.
278 gfs_controld_var_log_t
282 - Set files with the gfs_controld_var_log_t type, if you want to treat
284 the data as gfs controld var log data, usually stored under the
285 /var/log directory.
286 gfs_controld_var_run_t
290 - Set files with the gfs_controld_var_run_t type, if you want to store
292 the gfs controld files under the /run or /var/run directory.
293 Note: File context can be temporarily modified with the chcon command.
297 If you want to permanently change the file context you need to use the
298 semanage fcontext command. This will modify the SELinux labeling data‐
299 base. You will need to use restorecon to apply the labels.
300
303 semanage fcontext can also be used to manipulate default file context
304 mappings.
305 semanage permissive can also be used to manipulate whether or not a
307 process type is permissive.
308 semanage module can also be used to enable/disable/install/remove pol‐
310 icy modules.
311 semanage boolean can also be used to manipulate the booleans
313 system-config-selinux is a GUI tool available to customize SELinux pol‐
316 icy settings.
