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 clus‐
62 ter_use_execmem 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.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux gfs_controld policy is very flexible allowing users to setup
146 their gfs_controld processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the gfs_controld, if you
151 wanted to store files with these types in a diffent paths, you need to
152 execute the semanage command to sepecify alternate labeling and then
153 use restorecon to put the labels on disk.
154 semanage fcontext -a -t gfs_controld_var_run_t '/srv/mygfs_con‐
156 trold_content(/.*)?'
157 restorecon -R -v /srv/mygfs_controld_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for gfs_controld:
163 gfs_controld_exec_t
167 - Set files with the gfs_controld_exec_t type, if you want to transi‐
169 tion an executable to the gfs_controld_t domain.
170 gfs_controld_tmpfs_t
174 - Set files with the gfs_controld_tmpfs_t type, if you want to store
176 gfs controld files on a tmpfs file system.
177 gfs_controld_var_log_t
181 - Set files with the gfs_controld_var_log_t type, if you want to treat
183 the data as gfs controld var log data, usually stored under the
184 /var/log directory.
185 gfs_controld_var_run_t
189 - Set files with the gfs_controld_var_run_t type, if you want to store
191 the gfs controld files under the /run or /var/run directory.
192 Note: File context can be temporarily modified with the chcon command.
196 If you want to permanently change the file context you need to use the
197 semanage fcontext command. This will modify the SELinux labeling data‐
198 base. You will need to use restorecon to apply the labels.
199
202 semanage fcontext can also be used to manipulate default file context
203 mappings.
204 semanage permissive can also be used to manipulate whether or not a
206 process type is permissive.
207 semanage module can also be used to enable/disable/install/remove pol‐
209 icy modules.
210 semanage boolean can also be used to manipulate the booleans
212 system-config-selinux is a GUI tool available to customize SELinux pol‐
215 icy settings.
