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.
57 If you want to allow cluster administrative cluster domains memcheck-
61 amd64- to use executable memory, you must turn on the cluster_use_ex‐
62 ecmem boolean. Disabled by default.
63 setsebool -P cluster_use_execmem 1
65 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 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1
79
83 The SELinux process type gfs_controld_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.

154 SELinux requires files to have an extended attribute to define the file
155 type.
156 You can see the context of a file using the -Z option to ls
158 Policy governs the access confined processes have to these files.
160 SELinux gfs_controld policy is very flexible allowing users to setup
161 their gfs_controld processes in as secure a method as possible.
162 STANDARD FILE CONTEXT
164 SELinux defines the file context types for the gfs_controld, if you
166 wanted to store files with these types in a diffent paths, you need to
167 execute the semanage command to specify alternate labeling and then use
168 restorecon to put the labels on disk.
169 semanage fcontext -a -t gfs_controld_var_run_t '/srv/mygfs_con‐
171 trold_content(/.*)?'
172 restorecon -R -v /srv/mygfs_controld_content
173 Note: SELinux often uses regular expressions to specify labels that
175 match multiple files.
176 The following file types are defined for gfs_controld:
178 gfs_controld_exec_t
182 - Set files with the gfs_controld_exec_t type, if you want to transi‐
184 tion an executable to the gfs_controld_t domain.
185 gfs_controld_tmpfs_t
189 - Set files with the gfs_controld_tmpfs_t type, if you want to store
191 gfs controld files on a tmpfs file system.
192 gfs_controld_var_log_t
196 - Set files with the gfs_controld_var_log_t type, if you want to treat
198 the data as gfs controld var log data, usually stored under the
199 /var/log directory.
200 gfs_controld_var_run_t
204 - Set files with the gfs_controld_var_run_t type, if you want to store
206 the gfs controld files under the /run or /var/run directory.
207 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage boolean can also be used to manipulate the booleans
227 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
