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

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/groupadd,
31       /usr/sbin/groupdel, /usr/sbin/groupmod
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 al‐
56       low you to manipulate the policy and run groupadd with the tightest ac‐
57       cess possible.
58
59
60
61       If you want to allow all domains to execute in fips_mode, you must turn
62       on the fips_mode boolean. Enabled by default.
63
64       setsebool -P fips_mode 1
65
66
67
68       If you want to allow system to run with  NIS,  you  must  turn  on  the
69       nis_enabled boolean. Disabled by default.
70
71       setsebool -P nis_enabled 1
72
73
74
75       If  you want to allow samba to act as the domain controller, add users,
76       groups and change passwords, you must  turn  on  the  samba_domain_con‐
77       troller boolean. Disabled by default.
78
79       setsebool -P samba_domain_controller 1

MANAGED FILES

84       The  SELinux  process type groupadd_t can manage files labeled with the
85       following file types.  The paths listed are the default paths for these
86       file types.  Note the processes UID still need to have DAC permissions.
87
88       faillog_t
89
90            /var/log/btmp.*
91            /var/log/faillog.*

FILE CONTEXTS

129       SELinux requires files to have an extended attribute to define the file
130       type.
131
132       You can see the context of a file using the -Z option to ls
133
134       Policy governs the access  confined  processes  have  to  these  files.
135       SELinux  groupadd policy is very flexible allowing users to setup their
136       groupadd processes in as secure a method as possible.
137
138       STANDARD FILE CONTEXT
139
140       SELinux defines the file context types for the groupadd, if you  wanted
141       to  store files with these types in a different paths, you need to exe‐
142       cute the semanage command to specify alternate labeling  and  then  use
143       restorecon to put the labels on disk.
144
145       semanage fcontext -a -t groupadd_exec_t '/srv/groupadd/content(/.*)?'
146       restorecon -R -v /srv/mygroupadd_content
147
148       Note:  SELinux  often  uses  regular expressions to specify labels that
149       match multiple files.
150
151       The following file types are defined for groupadd:
152
153
154
155       groupadd_exec_t
156
157       - Set files with the groupadd_exec_t type, if you want to transition an
158       executable to the groupadd_t domain.
159
160
161       Paths:
162            /usr/bin/gpasswd,      /usr/sbin/gpasswd,      /usr/sbin/groupadd,
163            /usr/sbin/groupdel, /usr/sbin/groupmod
164
165
166       Note: File context can be temporarily modified with the chcon  command.
167       If  you want to permanently change the file context you need to use the
168       semanage fcontext command.  This will modify the SELinux labeling data‐
169       base.  You will need to use restorecon to apply the labels.

COMMANDS

173       semanage  fcontext  can also be used to manipulate default file context
174       mappings.
175
176       semanage permissive can also be used to manipulate  whether  or  not  a
177       process type is permissive.
178
179       semanage  module can also be used to enable/disable/install/remove pol‐
180       icy modules.
181
182       semanage boolean can also be used to manipulate the booleans
183
184
185       system-config-selinux is a GUI tool available to customize SELinux pol‐
186       icy settings.
