6 local_login_selinux - Security Enhanced Linux Policy for the
7 local_login 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
40 local_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.
54 local_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. Disabled 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.

178 SELinux requires files to have an extended attribute to define the file
179 type.
180
181 You can see the context of a file using the -Z option to ls
182
183 Policy governs the access confined processes have to these files.
184 SELinux local_login policy is very flexible allowing users to setup
185 their local_login processes in as secure a method as possible.
186
187 STANDARD FILE CONTEXT
188
189 SELinux defines the file context types for the local_login, if you
190 wanted to store files with these types in a diffent paths, you need to
191 execute the semanage command to sepecify alternate labeling and then
192 use restorecon to put the labels on disk.
193
194 semanage fcontext -a -t local_login_lock_t '/srv/mylocal_login_con‐
195 tent(/.*)?'
196 restorecon -R -v /srv/mylocal_login_content
197
198 Note: SELinux often uses regular expressions to specify labels that
199 match multiple files.
200
201 The following file types are defined for local_login:
202
203
204
205 local_login_home_t
206
207 - Set files with the local_login_home_t type, if you want to store
208 local login files in the users home directory.
209
210
211 Paths:
212 /root/.hushlogin, /home/[^/]+/.hushlogin
213
214
215 local_login_lock_t
216
217 - Set files with the local_login_lock_t type, if you want to treat the
218 files as local login lock data, stored under the /var/lock directory
219
220
221
222 Note: File context can be temporarily modified with the chcon command.
223 If you want to permanently change the file context you need to use the
224 semanage fcontext command. This will modify the SELinux labeling data‐
225 base. You will need to use restorecon to apply the labels.
226
227
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231
232 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234
235 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237
238 semanage boolean can also be used to manipulate the booleans
239
240
241 system-config-selinux is a GUI tool available to customize SELinux pol‐
242 icy settings.
