NAME

6       groupadd_selinux - Security Enhanced Linux Policy for the groupadd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  groupadd  processes  via  flexible
11       mandatory access control.
12
13       The  groupadd  processes  execute with the groupadd_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep groupadd_t
20
21
22

ENTRYPOINTS

24       The groupadd_t SELinux type can be entered via the groupadd_exec_t file
25       type.
26
27       The default entrypoint paths for the groupadd_t domain are the  follow‐
28       ing:
29
30       /usr/bin/gpasswd,         /usr/sbin/gpasswd,        /usr/sbin/groupdel,
31       /usr/sbin/groupmod, /usr/sbin/groupadd
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       groupadd policy is very flexible allowing users to setup their groupadd
41       processes in as secure a method as possible.
42
43       The following process types are defined for groupadd:
44
45       groupadd_t
46
47       Note: semanage permissive -a groupadd_t can be used to make the process
48       type groupadd_t permissive. SELinux does not deny access to  permissive
49       process  types, but the AVC (SELinux denials) messages are still gener‐
50       ated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       groupadd  policy  is  extremely  flexible and has several booleans that
56       allow you to manipulate the policy and run groupadd with  the  tightest
57       access possible.

59
60
61       If  you  want to allow all daemons the ability to read/write terminals,
62       you  must  turn  on  the  allow_daemons_use_tty  boolean.  Disabled  by
63       default.

91       allow_ypbind boolean. Disabled by default.
92
93       setsebool -P allow_ypbind 1
94
95
96
97       If  you  want to allow all domains to have the kernel load modules, you
98       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
99       default.
100
101       setsebool -P domain_kernel_load_modules 1
102
103
104
105       If you want to allow all domains to execute in fips_mode, you must turn

107
108       setsebool -P fips_mode 1
109
110
111
112       If you want to enable reading of urandom for all domains, you must turn
113       on the global_ssp boolean. Disabled by default.

127       groups  and  change  passwords,  you must turn on the samba_domain_con‐
128       troller boolean. Disabled by default.

MANAGED FILES

135       The SELinux process type groupadd_t can manage files labeled  with  the
136       following file types.  The paths listed are the default paths for these
137       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

216       SELinux requires files to have an extended attribute to define the file
217       type.
218
219       You can see the context of a file using the -Z option to ls
220
221       Policy  governs  the  access  confined  processes  have to these files.
222       SELinux groupadd policy is very flexible allowing users to setup  their
223       groupadd processes in as secure a method as possible.
224
225       The following file types are defined for groupadd:
226
227
228
229       groupadd_exec_t
230
231       - Set files with the groupadd_exec_t type, if you want to transition an
232       executable to the groupadd_t domain.
233
234
235       Paths:
236            /usr/bin/gpasswd,      /usr/sbin/gpasswd,      /usr/sbin/groupdel,
237            /usr/sbin/groupmod, /usr/sbin/groupadd
238
239
240       Note:  File context can be temporarily modified with the chcon command.
241       If you want to permanently change the file context you need to use  the
242       semanage fcontext command.  This will modify the SELinux labeling data‐
243       base.  You will need to use restorecon to apply the labels.
244
245

COMMANDS

247       semanage fcontext can also be used to manipulate default  file  context
248       mappings.
249
250       semanage  permissive  can  also  be used to manipulate whether or not a
251       process type is permissive.
252
253       semanage module can also be used to enable/disable/install/remove  pol‐
254       icy modules.
255
256       semanage boolean can also be used to manipulate the booleans
257
258
259       system-config-selinux is a GUI tool available to customize SELinux pol‐
260       icy settings.
