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
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
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
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.
49
50
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.

56
57
58 If you want to allow cluster administrative cluster domains memcheck-
59 amd64- to use executable memory, you must turn on the cluster_use_ex‐
60 ecmem boolean. Disabled by default.
61
62 setsebool -P cluster_use_execmem 1
63
64
65
66 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
69 setsebool -P fips_mode 1
70
71
72
73 If you want to allow system to run with NIS, you must turn on the
74 nis_enabled boolean. Disabled by default.
75
76 setsebool -P nis_enabled 1
77

79
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.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149
150 You can see the context of a file using the -Z option to ls
151
152 Policy governs the access confined processes have to these files.
153 SELinux groupd policy is very flexible allowing users to setup their
154 groupd processes in as secure a method as possible.
155
156 STANDARD FILE CONTEXT
157
158 SELinux defines the file context types for the groupd, if you wanted to
159 store files with these types in a diffent paths, you need to execute
160 the semanage command to specify alternate labeling and then use re‐
161 storecon to put the labels on disk.
162
163 semanage fcontext -a -t groupd_var_run_t '/srv/mygroupd_content(/.*)?'
164 restorecon -R -v /srv/mygroupd_content
165
166 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168
169 The following file types are defined for groupd:
170
171
172
173 groupd_exec_t
174
175 - Set files with the groupd_exec_t type, if you want to transition an
176 executable to the groupd_t domain.
177
178
179
180 groupd_tmpfs_t
181
182 - Set files with the groupd_tmpfs_t type, if you want to store groupd
183 files on a tmpfs file system.
184
185
186
187 groupd_var_log_t
188
189 - Set files with the groupd_var_log_t type, if you want to treat the
190 data as groupd var log data, usually stored under the /var/log direc‐
191 tory.
192
193
194
195 groupd_var_run_t
196
197 - Set files with the groupd_var_run_t type, if you want to store the
198 groupd files under the /run or /var/run directory.
199
200
201
202 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
207
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211
212 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214
215 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217
218 semanage boolean can also be used to manipulate the booleans
219
220
221 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
