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.
55 If you want to allow cluster administrative cluster domains memcheck-
59 amd64- to use executable memory, you must turn on the clus‐
60 ter_use_execmem boolean. Disabled by default.
61 setsebool -P cluster_use_execmem 1
63 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68 setsebool -P fips_mode 1
70 If you want to allow system to run with NIS, you must turn on the
74 nis_enabled boolean. Disabled by default.
75 setsebool -P nis_enabled 1

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

132 SELinux requires files to have an extended attribute to define the file
133 type.
134 You can see the context of a file using the -Z option to ls
136 Policy governs the access confined processes have to these files.
138 SELinux groupd policy is very flexible allowing users to setup their
139 groupd processes in as secure a method as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the groupd, if you wanted to
144 store files with these types in a diffent paths, you need to execute
145 the semanage command to sepecify alternate labeling and then use
146 restorecon to put the labels on disk.
147 semanage fcontext -a -t groupd_var_run_t '/srv/mygroupd_content(/.*)?'
149 restorecon -R -v /srv/mygroupd_content
150 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153 The following file types are defined for groupd:
155 groupd_exec_t
159 - Set files with the groupd_exec_t type, if you want to transition an
161 executable to the groupd_t domain.
162 groupd_tmpfs_t
166 - Set files with the groupd_tmpfs_t type, if you want to store groupd
168 files on a tmpfs file system.
169 groupd_var_log_t
173 - Set files with the groupd_var_log_t type, if you want to treat the
175 data as groupd var log data, usually stored under the /var/log direc‐
176 tory.
177 groupd_var_run_t
181 - Set files with the groupd_var_run_t type, if you want to store the
183 groupd files under the /run or /var/run directory.
184 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
