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 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 For example:
18 ps -eZ | grep local_login_t
20
24 The local_login_t SELinux type can be entered via the login_exec_t file
25 type.
26 The default entrypoint paths for the local_login_t domain are the fol‐
28 lowing:
29 /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 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for local_login:
43 local_login_t
45 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
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 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow logging in and using the system from /dev/console,
83 you must turn on the login_console_enabled boolean. Enabled by default.
84 setsebool -P login_console_enabled 1
86 If you want to allow system to run with NIS, you must turn on the
90 nis_enabled boolean. Disabled by default.
91 setsebool -P nis_enabled 1
93 If you want to allow confined applications to use nscd shared memory,
97 you must turn on the nscd_use_shm boolean. Disabled by default.
98 setsebool -P nscd_use_shm 1
100 If you want to enable polyinstantiated directory support, you must turn
104 on the polyinstantiation_enabled boolean. Disabled by default.
105 setsebool -P polyinstantiation_enabled 1

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

220 SELinux requires files to have an extended attribute to define the file
221 type.
222 You can see the context of a file using the -Z option to ls
224 Policy governs the access confined processes have to these files.
226 SELinux local_login policy is very flexible allowing users to setup
227 their local_login processes in as secure a method as possible.
228 STANDARD FILE CONTEXT
230 SELinux defines the file context types for the local_login, if you
232 wanted to store files with these types in a diffent paths, you need to
233 execute the semanage command to sepecify alternate labeling and then
234 use restorecon to put the labels on disk.
235 semanage fcontext -a -t local_login_lock_t '/srv/mylocal_login_con‐
237 tent(/.*)?'
238 restorecon -R -v /srv/mylocal_login_content
239 Note: SELinux often uses regular expressions to specify labels that
241 match multiple files.
242 The following file types are defined for local_login:
244 local_login_home_t
248 - Set files with the local_login_home_t type, if you want to store
250 local login files in the users home directory.
251 Paths:
254 /root/.hushlogin, /home/[^/]+/.hushlogin
255 local_login_lock_t
258 - Set files with the local_login_lock_t type, if you want to treat the
260 files as local login lock data, stored under the /var/lock directory
261 Note: File context can be temporarily modified with the chcon command.
265 If you want to permanently change the file context you need to use the
266 semanage fcontext command. This will modify the SELinux labeling data‐
267 base. You will need to use restorecon to apply the labels.
268
271 semanage fcontext can also be used to manipulate default file context
272 mappings.
273 semanage permissive can also be used to manipulate whether or not a
275 process type is permissive.
276 semanage module can also be used to enable/disable/install/remove pol‐
278 icy modules.
279 semanage boolean can also be used to manipulate the booleans
281 system-config-selinux is a GUI tool available to customize SELinux pol‐
284 icy settings.
