6 local_login_selinux - Security Enhanced Linux Policy for the local_lo‐
7 gin processes
8
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
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
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
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
92
93
94
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.

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
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.
