NAME

6       useradd_selinux  -  Security Enhanced Linux Policy for the useradd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  useradd  processes  via  flexible
11       mandatory access control.
12
13       The  useradd processes execute with the useradd_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 useradd_t
20
21
22

ENTRYPOINTS

24       The  useradd_t  SELinux  type  can  be  entered via the useradd_exec_t,
25       user_home_t file types.
26
27       The default entrypoint paths for the useradd_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/useradd,         /usr/sbin/userdel,        /usr/sbin/usermod,
31       /usr/sbin/newusers, /home/[^/]+/.+
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       useradd policy is very flexible allowing users to setup  their  useradd
41       processes in as secure a method as possible.
42
43       The following process types are defined for useradd:
44
45       useradd_t
46
47       Note:  semanage permissive -a useradd_t can be used to make the process
48       type useradd_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.  useradd
55       policy is extremely flexible and has several booleans that allow you to
56       manipulate the policy and run useradd with the tightest  access  possi‐
57       ble.
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
80
81
82
83       If  you  want  to  support  NFS  home directories, you must turn on the
84       use_nfs_home_dirs boolean. Disabled by default.
85
86       setsebool -P use_nfs_home_dirs 1
87
88
89
90       If you want to support SAMBA home directories, you  must  turn  on  the
91       use_samba_home_dirs boolean. Disabled by default.
92
93       setsebool -P use_samba_home_dirs 1

MANAGED FILES

98       The  SELinux  process  type useradd_t can manage files labeled with the
99       following file types.  The paths listed are the default paths for these
100       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

218       SELinux requires files to have an extended attribute to define the file
219       type.
220
221       You can see the context of a file using the -Z option to ls
222
223       Policy governs the access  confined  processes  have  to  these  files.
224       SELinux  useradd  policy is very flexible allowing users to setup their
225       useradd processes in as secure a method as possible.
226
227       STANDARD FILE CONTEXT
228
229       SELinux defines the file context types for the useradd, if  you  wanted
230       to store files with these types in a diffent paths, you need to execute
231       the semanage command to sepecify alternate labeling and  then  use  re‐
232       storecon to put the labels on disk.
233
234       semanage   fcontext   -a   -t   useradd_var_run_t  '/srv/myuseradd_con‐
235       tent(/.*)?'
236       restorecon -R -v /srv/myuseradd_content
237
238       Note: SELinux often uses regular expressions  to  specify  labels  that
239       match multiple files.
240
241       The following file types are defined for useradd:
242
243
244
245       useradd_exec_t
246
247       -  Set files with the useradd_exec_t type, if you want to transition an
248       executable to the useradd_t domain.
249
250
251       Paths:
252            /usr/sbin/useradd,      /usr/sbin/userdel,      /usr/sbin/usermod,
253            /usr/sbin/newusers
254
255
256       useradd_var_run_t
257
258       -  Set  files with the useradd_var_run_t type, if you want to store the
259       useradd files under the /run or /var/run directory.
260
261
262
263       Note: File context can be temporarily modified with the chcon  command.
264       If  you want to permanently change the file context you need to use the
265       semanage fcontext command.  This will modify the SELinux labeling data‐
266       base.  You will need to use restorecon to apply the labels.
267
268

COMMANDS

270       semanage  fcontext  can also be used to manipulate default file context
271       mappings.
272
273       semanage permissive can also be used to manipulate  whether  or  not  a
274       process type is permissive.
275
276       semanage  module can also be used to enable/disable/install/remove pol‐
277       icy modules.
278
279       semanage boolean can also be used to manipulate the booleans
280
281
282       system-config-selinux is a GUI tool available to customize SELinux pol‐
283       icy settings.
