NAME

6       local_login_selinux  - Security Enhanced Linux Policy for the local_lo‐
7       gin processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The local_login_t SELinux type can be entered via the login_exec_t file
25       type.
26
27       The default entrypoint paths for the local_login_t domain are the  fol‐
28       lowing:
29
30       /bin/login, /usr/bin/login, /usr/kerberos/sbin/login.krb5
31

PROCESS TYPES

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

BOOLEANS

53       SELinux  policy  is  customizable  based on least access required.  lo‐
54       cal_login policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run local_login with the tight‐
56       est access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the kerberos_enabled boolean. Enabled by default.
69
70       setsebool -P kerberos_enabled 1
71
72
73
74       If you want to allow logging in and using the system from /dev/console,
75       you must turn on the login_console_enabled boolean. Enabled by default.
76
77       setsebool -P login_console_enabled 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       nis_enabled boolean. Disabled by default.
83
84       setsebool -P nis_enabled 1
85
86
87
88       If you want to enable polyinstantiated directory support, you must turn
89       on the polyinstantiation_enabled boolean. Disabled by default.
90
91       setsebool -P polyinstantiation_enabled 1

MANAGED FILES

96       The  SELinux  process  type local_login_t can manage files labeled with
97       the following file types.  The paths listed are the default  paths  for
98       these  file  types.  Note the processes UID still need to have DAC per‐
99       missions.

FILE CONTEXTS

200       SELinux requires files to have an extended attribute to define the file
201       type.
202
203       You can see the context of a file using the -Z option to ls
204
205       Policy  governs  the  access  confined  processes  have to these files.
206       SELinux local_login policy is very flexible  allowing  users  to  setup
207       their local_login processes in as secure a method as possible.
208
209       STANDARD FILE CONTEXT
210
211       SELinux  defines  the  file  context  types for the local_login, if you
212       wanted to store files with these types in a diffent paths, you need  to
213       execute the semanage command to specify alternate labeling and then use
214       restorecon to put the labels on disk.
215
216       semanage fcontext  -a  -t  local_login_lock_t  '/srv/mylocal_login_con‐
217       tent(/.*)?'
218       restorecon -R -v /srv/mylocal_login_content
219
220       Note:  SELinux  often  uses  regular expressions to specify labels that
221       match multiple files.
222
223       The following file types are defined for local_login:
224
225
226
227       local_login_home_t
228
229       - Set files with the local_login_home_t type, if you want to store  lo‐
230       cal login files in the users home directory.
231
232
233       Paths:
234            /root/.hushlogin, /home/[^/]+/.hushlogin
235
236
237       local_login_lock_t
238
239       -  Set files with the local_login_lock_t type, if you want to treat the
240       files as local login lock data, stored under the /var/lock directory
241
242
243
244       Note: File context can be temporarily modified with the chcon  command.
245       If  you want to permanently change the file context you need to use the
246       semanage fcontext command.  This will modify the SELinux labeling data‐
247       base.  You will need to use restorecon to apply the labels.
248
249

COMMANDS

251       semanage  fcontext  can also be used to manipulate default file context
252       mappings.
253
254       semanage permissive can also be used to manipulate  whether  or  not  a
255       process type is permissive.
256
257       semanage  module can also be used to enable/disable/install/remove pol‐
258       icy modules.
259
260       semanage boolean can also be used to manipulate the booleans
261
262
263       system-config-selinux is a GUI tool available to customize SELinux pol‐
264       icy settings.
