6 groupd_selinux - Security Enhanced Linux Policy for the groupd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the groupd processes via flexible
11 mandatory access control.
12 The groupd processes execute with the groupd_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 groupd_t
20
24 The groupd_t SELinux type can be entered via the groupd_exec_t file
25 type.
26 The default entrypoint paths for the groupd_t domain are the following:
28 /usr/sbin/groupd
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 groupd policy is very flexible allowing users to setup their groupd
39 processes in as secure a method as possible.
40 The following process types are defined for groupd:
42 groupd_t
44 Note: semanage permissive -a groupd_t can be used to make the process
46 type groupd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. groupd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run groupd with the tightest access possible.

153 you must turn on the nscd_use_shm boolean. Enabled by default.
154 setsebool -P nscd_use_shm 1

160 The SELinux process type groupd_t can manage files labeled with the
161 following file types. The paths listed are the default paths for these
162 file types. Note the processes UID still need to have DAC permissions.

233 SELinux requires files to have an extended attribute to define the file
234 type.
235 You can see the context of a file using the -Z option to ls
237 Policy governs the access confined processes have to these files.
239 SELinux groupd policy is very flexible allowing users to setup their
240 groupd processes in as secure a method as possible.
241 STANDARD FILE CONTEXT
243 SELinux defines the file context types for the groupd, if you wanted to
245 store files with these types in a diffent paths, you need to execute
246 the semanage command to sepecify alternate labeling and then use
247 restorecon to put the labels on disk.
248 semanage fcontext -a -t groupd_var_run_t '/srv/mygroupd_content(/.*)?'
250 restorecon -R -v /srv/mygroupd_content
251 Note: SELinux often uses regular expressions to specify labels that
253 match multiple files.
254 The following file types are defined for groupd:
256 groupd_exec_t
260 - Set files with the groupd_exec_t type, if you want to transition an
262 executable to the groupd_t domain.
263 groupd_tmpfs_t
267 - Set files with the groupd_tmpfs_t type, if you want to store groupd
269 files on a tmpfs file system.
270 groupd_var_log_t
274 - Set files with the groupd_var_log_t type, if you want to treat the
276 data as groupd var log data, usually stored under the /var/log direc‐
277 tory.
278 groupd_var_run_t
282 - Set files with the groupd_var_run_t type, if you want to store the
284 groupd files under the /run or /var/run directory.
285 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303 semanage boolean can also be used to manipulate the booleans
305 system-config-selinux is a GUI tool available to customize SELinux pol‐
308 icy settings.
