NAME

6       init_selinux - Security Enhanced Linux Policy for the init processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The  init_t  SELinux  type  can  be  entered   via   the   init_exec_t,
24       shell_exec_t file types.
25
26       The default entrypoint paths for the init_t domain are the following:
27
28       /sbin/init(ng)?,      /usr/sbin/init(ng)?,      /usr/lib/systemd/[^/]*,
29       /usr/lib/systemd/system-generators/[^/]*, /bin/systemd,  /sbin/upstart,
30       /usr/bin/systemd,     /usr/sbin/upstart,     /bin/d?ash,    /bin/ksh.*,
31       /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*,  /usr/bin/zsh.*,  /bin/esh,
32       /bin/bash,   /bin/fish,  /bin/mksh,  /bin/sash,  /bin/tcsh,  /bin/yash,
33       /bin/bash2, /usr/bin/esh, /sbin/nologin, /usr/bin/bash,  /usr/bin/fish,
34       /usr/bin/mksh,     /usr/bin/sash,     /usr/bin/tcsh,     /usr/bin/yash,

PROCESS TYPES

41       SELinux defines process types (domains) for each process running on the
42       system
43
44       You can see the context of a process using the -Z option to ps
45
46       Policy governs the access confined processes have  to  files.   SELinux
47       init  policy  is  very flexible allowing users to setup their init pro‐
48       cesses in as secure a method as possible.
49
50       The following process types are defined for init:
51
52       init_t, initrc_t
53
54       Note: semanage permissive -a init_t can be used  to  make  the  process
55       type  init_t  permissive.  SELinux  does  not deny access to permissive
56       process types, but the AVC (SELinux denials) messages are still  gener‐
57       ated.
58
59

BOOLEANS

61       SELinux  policy  is  customizable based on least access required.  init
62       policy is extremely flexible and has several booleans that allow you to
63       manipulate the policy and run init with the tightest access possible.
64
65
66
67       If  you  want  to allow init audit_control capability, you must turn on
68       the init_audit_control boolean. Disabled by default.
69
70       setsebool -P init_audit_control 1
71
72
73
74       If you want to  enable  init  create,  setattr,  mounton  on  non_secu‐
75       rity_file_type,  you must turn on the init_create_dirs boolean. Enabled
76       by default.
77
78       setsebool -P init_create_dirs 1
79
80
81
82       If you want to deny all system processes and Linux users to  use  blue‐
83       tooth wireless technology, you must turn on the deny_bluetooth boolean.
84       Enabled by default.
85
86       setsebool -P deny_bluetooth 1
87
88
89
90       If you want to allow all domains to execute in fips_mode, you must turn
91       on the fips_mode boolean. Enabled by default.
92
93       setsebool -P fips_mode 1
94
95
96
97       If  you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
98       you must turn on the nagios_run_sudo boolean. Disabled by default.
99
100       setsebool -P nagios_run_sudo 1
101
102
103
104       If you want to disable kernel module loading, you must turn on the  se‐
105       cure_mode_insmod boolean. Enabled by default.
106
107       setsebool -P secure_mode_insmod 1
108

MANAGED FILES

112       The  SELinux process type init_t can manage files labeled with the fol‐
113       lowing file types.  The paths listed are the default  paths  for  these
114       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

283       SELinux requires files to have an extended attribute to define the file
284       type.
285
286       You can see the context of a file using the -Z option to ls
287
288       Policy governs the access  confined  processes  have  to  these  files.
289       SELinux init policy is very flexible allowing users to setup their init
290       processes in as secure a method as possible.
291
292       EQUIVALENCE DIRECTORIES
293
294
295       init policy stores data with multiple different file context types  un‐
296       der  the  /var/run/systemd  directory.   If you would like to store the
297       data in a different directory you can use the semanage command to  cre‐
298       ate an equivalence mapping.  If you wanted to store this data under the
299       /srv directory you would execute the following command:
300
301       semanage fcontext -a -e /var/run/systemd /srv/systemd
302       restorecon -R -v /srv/systemd
303
304       STANDARD FILE CONTEXT
305
306       SELinux defines the file context types for the init, if you  wanted  to
307       store  files  with  these types in a diffent paths, you need to execute
308       the semanage command to specify alternate labeling  and  then  use  re‐
309       storecon to put the labels on disk.
310
311       semanage fcontext -a -t initrc_var_run_t '/srv/myinit_content(/.*)?'
312       restorecon -R -v /srv/myinit_content
313
314       Note:  SELinux  often  uses  regular expressions to specify labels that
315       match multiple files.
316
317       The following file types are defined for init:
318
319
320
321       init_exec_t
322
323       - Set files with the init_exec_t type, if you want to transition an ex‐
324       ecutable to the init_t domain.
325
326
327       Paths:
328            /sbin/init(ng)?,    /usr/sbin/init(ng)?,   /usr/lib/systemd/[^/]*,
329            /usr/lib/systemd/system-generators/[^/]*, /bin/systemd,  /sbin/up‐
330            start, /usr/bin/systemd, /usr/sbin/upstart

347            /var/lib/systemd(/.*)?, /var/lib/private/systemd(/.*)?
348
349
350       init_var_run_t
351
352       - Set files with the init_var_run_t type, if you want to store the init
353       files under the /run or /var/run directory.
354
355
356
357       initctl_t
358
359       - Set files with the initctl_t type, if you want to treat the files  as
360       initctl data.

368
369       -  Set  files  with  the initrc_devpts_t type, if you want to treat the
370       files as initrc devpts data.
371
372
373
374       initrc_exec_t
375
376       - Set files with the initrc_exec_t type, if you want to  transition  an
377       executable to the initrc_t domain.
378
379
380       Paths:
381            /etc/init.d/.*,      /etc/rc.d/rc.[^/]+,      /etc/rc.d/init.d/.*,

388            vices/system-config-services-mechanism.py
389
390
391       initrc_state_t
392
393       - Set files with the initrc_state_t type, if  you  want  to  treat  the
394       files as initrc state data.

409       tory.

421            /var/run/setmixer_flag
422
423
424       Note: File context can be temporarily modified with the chcon  command.
425       If  you want to permanently change the file context you need to use the
426       semanage fcontext command.  This will modify the SELinux labeling data‐
427       base.  You will need to use restorecon to apply the labels.
428
429

COMMANDS

431       semanage  fcontext  can also be used to manipulate default file context
432       mappings.
433
434       semanage permissive can also be used to manipulate  whether  or  not  a
435       process type is permissive.
436
437       semanage  module can also be used to enable/disable/install/remove pol‐
438       icy modules.
439
440       semanage boolean can also be used to manipulate the booleans
441
442
443       system-config-selinux is a GUI tool available to customize SELinux pol‐
444       icy settings.
