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 users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61 setsebool -P authlogin_nsswitch_use_ldap 1
63 If you want to allow cluster administrative cluster domains memcheck-
67 amd64- to use executable memory, you must turn on the clus‐
68 ter_use_execmem boolean. Disabled by default.
69 setsebool -P cluster_use_execmem 1
71 If you want to allow all domains to execute in fips_mode, you must turn
75 on the fips_mode boolean. Enabled by default.
76 setsebool -P fips_mode 1
78 If you want to allow confined applications to run with kerberos, you
82 must turn on the kerberos_enabled boolean. Enabled by default.
83 setsebool -P kerberos_enabled 1
85 If you want to allow system to run with NIS, you must turn on the
89 nis_enabled boolean. Disabled by default.
90 setsebool -P nis_enabled 1
92 If you want to allow confined applications to use nscd shared memory,
96 you must turn on the nscd_use_shm boolean. Disabled by default.
97 setsebool -P nscd_use_shm 1

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

157 SELinux requires files to have an extended attribute to define the file
158 type.
159 You can see the context of a file using the -Z option to ls
161 Policy governs the access confined processes have to these files.
163 SELinux groupd policy is very flexible allowing users to setup their
164 groupd processes in as secure a method as possible.
165 STANDARD FILE CONTEXT
167 SELinux defines the file context types for the groupd, if you wanted to
169 store files with these types in a diffent paths, you need to execute
170 the semanage command to sepecify alternate labeling and then use
171 restorecon to put the labels on disk.
172 semanage fcontext -a -t groupd_var_run_t '/srv/mygroupd_content(/.*)?'
174 restorecon -R -v /srv/mygroupd_content
175 Note: SELinux often uses regular expressions to specify labels that
177 match multiple files.
178 The following file types are defined for groupd:
180 groupd_exec_t
184 - Set files with the groupd_exec_t type, if you want to transition an
186 executable to the groupd_t domain.
187 groupd_tmpfs_t
191 - Set files with the groupd_tmpfs_t type, if you want to store groupd
193 files on a tmpfs file system.
194 groupd_var_log_t
198 - Set files with the groupd_var_log_t type, if you want to treat the
200 data as groupd var log data, usually stored under the /var/log direc‐
201 tory.
202 groupd_var_run_t
206 - Set files with the groupd_var_run_t type, if you want to store the
208 groupd files under the /run or /var/run directory.
209 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
