NAME

6       sulogin_selinux  -  Security Enhanced Linux Policy for the sulogin pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  sulogin  processes  via  flexible
11       mandatory access control.
12
13       The  sulogin processes execute with the sulogin_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 sulogin_t
20
21
22

ENTRYPOINTS

24       The  sulogin_t  SELinux type can be entered via the sulogin_exec_t file
25       type.
26
27       The default entrypoint paths for the sulogin_t domain are  the  follow‐
28       ing:
29
30       /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell
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       sulogin  policy  is very flexible allowing users to setup their sulogin
40       processes in as secure a method as possible.
41
42       The following process types are defined for sulogin:
43
44       sulogin_t
45
46       Note: semanage permissive -a sulogin_t can be used to make the  process
47       type  sulogin_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  sulogin
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run sulogin with the tightest access possi‐
56       ble.
57
58
59
60       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
64       setsebool -P authlogin_nsswitch_use_ldap 1

105
106       If you want to allow all domains to have the kernel load  modules,  you
107       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
108       default.
109
110       setsebool -P domain_kernel_load_modules 1
111
112
113
114       If you want to allow all domains to execute in fips_mode, you must turn
115       on the fips_mode boolean. Enabled by default.

MANAGED FILES

157       The SELinux process type sulogin_t can manage files  labeled  with  the
158       following file types.  The paths listed are the default paths for these
159       file types.  Note the processes UID still need to have DAC permissions.
160
161       security_t
162
163            /selinux
164
165

FILE CONTEXTS

167       SELinux requires files to have an extended attribute to define the file
168       type.
169
170       You can see the context of a file using the -Z option to ls
171
172       Policy  governs  the  access  confined  processes  have to these files.
173       SELinux sulogin policy is very flexible allowing users to  setup  their
174       sulogin processes in as secure a method as possible.
175
176       The following file types are defined for sulogin:
177
178
179
180       sulogin_exec_t
181
182       -  Set files with the sulogin_exec_t type, if you want to transition an
183       executable to the sulogin_t domain.
184
185
186       Paths:
187            /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell
188
189
190       Note: File context can be temporarily modified with the chcon  command.
191       If  you want to permanently change the file context you need to use the
192       semanage fcontext command.  This will modify the SELinux labeling data‐
193       base.  You will need to use restorecon to apply the labels.
194
195

COMMANDS

197       semanage  fcontext  can also be used to manipulate default file context
198       mappings.
199
200       semanage permissive can also be used to manipulate  whether  or  not  a
201       process type is permissive.
202
203       semanage  module can also be used to enable/disable/install/remove pol‐
204       icy modules.
205
206       semanage boolean can also be used to manipulate the booleans
207
208
209       system-config-selinux is a GUI tool available to customize SELinux pol‐
210       icy settings.
