NAME

6       setsebool_selinux  -  Security  Enhanced Linux Policy for the setsebool
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  setsebool_t  SELinux  type can be entered via the setsebool_exec_t
25       file type.
26
27       The default entrypoint paths for the setsebool_t domain are the follow‐
28       ing:
29
30       /usr/sbin/setsebool
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       setsebool  policy is very flexible allowing users to setup their setse‐
40       bool processes in as secure a method as possible.
41
42       The following process types are defined for setsebool:
43
44       setsebool_t
45
46       Note: semanage permissive -a  setsebool_t  can  be  used  to  make  the
47       process  type  setsebool_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.  setse‐
54       bool policy is extremely flexible and has several booleans  that  allow
55       you to manipulate the policy and run setsebool with the tightest access
56       possible.
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.

103
104
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

MANAGED FILES

159       The SELinux process type setsebool_t can manage files labeled with  the
160       following file types.  The paths listed are the default paths for these
161       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

237       SELinux requires files to have an extended attribute to define the file
238       type.
239
240       You can see the context of a file using the -Z option to ls
241
242       Policy  governs  the  access  confined  processes  have to these files.
243       SELinux setsebool policy is very flexible allowing users to setup their
244       setsebool processes in as secure a method as possible.
245
246       The following file types are defined for setsebool:
247
248
249
250       setsebool_exec_t
251
252       -  Set  files with the setsebool_exec_t type, if you want to transition
253       an executable to the setsebool_t domain.
254
255
256
257       Note: File context can be temporarily modified with the chcon  command.
258       If  you want to permanently change the file context you need to use the
259       semanage fcontext command.  This will modify the SELinux labeling data‐
260       base.  You will need to use restorecon to apply the labels.
261
262

COMMANDS

264       semanage  fcontext  can also be used to manipulate default file context
265       mappings.
266
267       semanage permissive can also be used to manipulate  whether  or  not  a
268       process type is permissive.
269
270       semanage  module can also be used to enable/disable/install/remove pol‐
271       icy modules.
272
273       semanage boolean can also be used to manipulate the booleans
274
275
276       system-config-selinux is a GUI tool available to customize SELinux pol‐
277       icy settings.
