NAME

6       groupd_selinux  -  Security  Enhanced  Linux Policy for the groupd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  groupd  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep groupd_t
20
21
22

ENTRYPOINTS

24       The  groupd_t  SELinux  type  can be entered via the groupd_exec_t file
25       type.
26
27       The default entrypoint paths for the groupd_t domain are the following:
28
29       /usr/sbin/groupd
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       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
41       The following process types are defined for groupd:
42
43       groupd_t
44
45       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.

BOOLEANS

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
56
57
58       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
62       setsebool -P authlogin_nsswitch_use_ldap 1
63
64
65
66       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
70       setsebool -P cluster_use_execmem 1
71
72
73
74       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
77       setsebool -P fips_mode 1
78
79
80
81       If  you  want  to allow confined applications to run with kerberos, you
82       must turn on the kerberos_enabled boolean. Enabled by default.
83
84       setsebool -P kerberos_enabled 1
85
86
87
88       If you want to allow system to run with  NIS,  you  must  turn  on  the
89       nis_enabled boolean. Disabled by default.
90
91       setsebool -P nis_enabled 1
92
93
94
95       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
98       setsebool -P nscd_use_shm 1

MANAGED FILES

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.
106
107       cluster_conf_t
108
109            /etc/cluster(/.*)?

FILE CONTEXTS

157       SELinux requires files to have an extended attribute to define the file
158       type.
159
160       You can see the context of a file using the -Z option to ls
161
162       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
166       STANDARD FILE CONTEXT
167
168       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
173       semanage fcontext -a -t groupd_var_run_t '/srv/mygroupd_content(/.*)?'
174       restorecon -R -v /srv/mygroupd_content
175
176       Note: SELinux often uses regular expressions  to  specify  labels  that
177       match multiple files.
178
179       The following file types are defined for groupd:
180
181
182
183       groupd_exec_t
184
185       -  Set  files with the groupd_exec_t type, if you want to transition an
186       executable to the groupd_t domain.
187
188
189
190       groupd_tmpfs_t
191
192       - Set files with the groupd_tmpfs_t type, if you want to  store  groupd
193       files on a tmpfs file system.
194
195
196
197       groupd_var_log_t
198
199       -  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
203
204
205       groupd_var_run_t
206
207       -  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
210
211
212       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
217

COMMANDS

219       semanage  fcontext  can also be used to manipulate default file context
220       mappings.
221
222       semanage permissive can also be used to manipulate  whether  or  not  a
223       process type is permissive.
224
225       semanage  module can also be used to enable/disable/install/remove pol‐
226       icy modules.
227
228       semanage boolean can also be used to manipulate the booleans
229
230
231       system-config-selinux is a GUI tool available to customize SELinux pol‐
232       icy settings.
