6 init_selinux - Security Enhanced Linux Policy for the init processes
7
9 Security-Enhanced Linux secures the init processes via flexible manda‐
10 tory access control.
11 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 For example:
17 ps -eZ | grep init_t
19
23 The init_t SELinux type can be entered via the shell_exec_t,
24 init_exec_t file types.
25 The default entrypoint paths for the init_t domain are the following:
27 /bin/d?ash, /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
29 /usr/bin/zsh.*, /bin/esh, /bin/bash, /bin/fish, /bin/mksh, /bin/sash,
30 /bin/tcsh, /bin/yash, /bin/bash2, /usr/bin/esh, /sbin/nologin,
31 /usr/bin/bash, /usr/bin/fish, /usr/bin/mksh, /usr/bin/sash,
32 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/bash2, /usr/sbin/sesh,
33 /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh, /usr/sbin/nolo‐
34 gin, /usr/bin/git-shell, /usr/sbin/scponlyc, /usr/libexec/sudo/sesh,
35 /usr/bin/cockpit-bridge, /usr/libexec/cockpit-agent, /usr/libexec/git-
36 core/git-shell, /sbin/init(ng)?, /usr/sbin/init(ng)?, /usr/lib/sys‐
37 temd/[^/]*, /usr/lib/systemd/system-generators/[^/]*, /bin/systemd,
38 /sbin/upstart, /usr/bin/systemd, /usr/sbin/upstart

41 SELinux defines process types (domains) for each process running on the
42 system
43 You can see the context of a process using the -Z option to ps
45 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 The following process types are defined for init:
51 init_t, initrc_t
53 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
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 If you want to allow users to resolve user passwd entries directly from
68 ldap rather then using a sssd server, you must turn on the authlo‐
69 gin_nsswitch_use_ldap boolean. Disabled by default.
70 setsebool -P authlogin_nsswitch_use_ldap 1
72 If you want to allow all domains to execute in fips_mode, you must turn
76 on the fips_mode boolean. Enabled by default.
77 setsebool -P fips_mode 1
79 If you want to allow confined applications to run with kerberos, you
83 must turn on the kerberos_enabled boolean. Enabled by default.
84 setsebool -P kerberos_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. Enabled by default.
98 setsebool -P nscd_use_shm 1
100 If you want to allow create vbox modules during startup new kernel, you
104 must turn on the use_virtualbox boolean. Disabled by default.
105 setsebool -P use_virtualbox 1
107
111 The SELinux process type init_t can manage files labeled with the fol‐
112 lowing file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.

444 SELinux requires files to have an extended attribute to define the file
445 type.
446 You can see the context of a file using the -Z option to ls
448 Policy governs the access confined processes have to these files.
450 SELinux init policy is very flexible allowing users to setup their init
451 processes in as secure a method as possible.
452 EQUIVALENCE DIRECTORIES
454 init policy stores data with multiple different file context types
457 under the /var/run/systemd directory. If you would like to store the
458 data in a different directory you can use the semanage command to cre‐
459 ate an equivalence mapping. If you wanted to store this data under the
460 /srv dirctory you would execute the following command:
461 semanage fcontext -a -e /var/run/systemd /srv/systemd
463 restorecon -R -v /srv/systemd
464 STANDARD FILE CONTEXT
466 SELinux defines the file context types for the init, if you wanted to
468 store files with these types in a diffent paths, you need to execute
469 the semanage command to sepecify alternate labeling and then use
470 restorecon to put the labels on disk.
471 semanage fcontext -a -t initrc_var_run_t '/srv/myinit_content(/.*)?'
473 restorecon -R -v /srv/myinit_content
474 Note: SELinux often uses regular expressions to specify labels that
476 match multiple files.
477 The following file types are defined for init:
479 init_exec_t
483 - Set files with the init_exec_t type, if you want to transition an
485 executable to the init_t domain.
486 Paths:
489 /sbin/init(ng)?, /usr/sbin/init(ng)?, /usr/lib/systemd/[^/]*,
490 /usr/lib/systemd/system-generators/[^/]*, /bin/systemd,
491 /sbin/upstart, /usr/bin/systemd, /usr/sbin/upstart
492 init_tmp_t
495 - Set files with the init_tmp_t type, if you want to store init tempo‐
497 rary files in the /tmp directories.
498 init_var_lib_t
502 - Set files with the init_var_lib_t type, if you want to store the init
504 files under the /var/lib directory.
505 Paths:
508 /var/lib/systemd(/.*)?, /var/lib/private/systemd(/.*)?
509 init_var_run_t
512 - Set files with the init_var_run_t type, if you want to store the init
514 files under the /run or /var/run directory.
515 initctl_t
519 - Set files with the initctl_t type, if you want to treat the files as
521 initctl data.
522 Paths:
525 /dev/initctl, /var/run/initctl, /var/run/systemd/initctl/fifo
526 initrc_devpts_t
529 - Set files with the initrc_devpts_t type, if you want to treat the
531 files as initrc devpts data.
532 initrc_exec_t
536 - Set files with the initrc_exec_t type, if you want to transition an
538 executable to the initrc_t domain.
539 Paths:
542 /etc/init.d/.*, /etc/rc.d/rc.[^/]+, /etc/rc.d/init.d/.*,
543 /opt/nfast/sbin/init.d-ncipher, /usr/libexec/dcc/stop-.*,
544 /usr/libexec/dcc/start-.*, /usr/lib/systemd/fedora[^/]*,
545 /opt/nfast/scripts/init.d/(.*), /etc/rc.d/rc, /etc/X11/prefdm,
546 /usr/sbin/startx, /usr/bin/sepg_ctl, /usr/sbin/apachectl,
547 /usr/sbin/start-dirsrv, /usr/sbin/open_init_pty,
548 /usr/sbin/restart-dirsrv, /etc/sysconfig/network-scripts/ifup-
549 ipsec, /usr/share/system-config-services/system-config-services-
550 mechanism.py
551 initrc_state_t
554 - Set files with the initrc_state_t type, if you want to treat the
556 files as initrc state data.
557 initrc_tmp_t
561 - Set files with the initrc_tmp_t type, if you want to store initrc
563 temporary files in the /tmp directories.
564 initrc_var_log_t
568 - Set files with the initrc_var_log_t type, if you want to treat the
570 data as initrc var log data, usually stored under the /var/log direc‐
571 tory.
572 initrc_var_run_t
576 - Set files with the initrc_var_run_t type, if you want to store the
578 initrc files under the /run or /var/run directory.
579 Paths:
582 /var/run/utmp, /var/run/random-seed, /var/run/runlevel.dir,
583 /var/run/setmixer_flag
584 Note: File context can be temporarily modified with the chcon command.
587 If you want to permanently change the file context you need to use the
588 semanage fcontext command. This will modify the SELinux labeling data‐
589 base. You will need to use restorecon to apply the labels.
590
593 semanage fcontext can also be used to manipulate default file context
594 mappings.
595 semanage permissive can also be used to manipulate whether or not a
597 process type is permissive.
598 semanage module can also be used to enable/disable/install/remove pol‐
600 icy modules.
601 semanage boolean can also be used to manipulate the booleans
603 system-config-selinux is a GUI tool available to customize SELinux pol‐
606 icy settings.
