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. Disabled 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.

448 SELinux requires files to have an extended attribute to define the file
449 type.
450 You can see the context of a file using the -Z option to ls
452 Policy governs the access confined processes have to these files.
454 SELinux init policy is very flexible allowing users to setup their init
455 processes in as secure a method as possible.
456 EQUIVALENCE DIRECTORIES
458 init policy stores data with multiple different file context types
461 under the /var/run/systemd directory. If you would like to store the
462 data in a different directory you can use the semanage command to cre‐
463 ate an equivalence mapping. If you wanted to store this data under the
464 /srv dirctory you would execute the following command:
465 semanage fcontext -a -e /var/run/systemd /srv/systemd
467 restorecon -R -v /srv/systemd
468 STANDARD FILE CONTEXT
470 SELinux defines the file context types for the init, if you wanted to
472 store files with these types in a diffent paths, you need to execute
473 the semanage command to sepecify alternate labeling and then use
474 restorecon to put the labels on disk.
475 semanage fcontext -a -t initrc_var_run_t '/srv/myinit_content(/.*)?'
477 restorecon -R -v /srv/myinit_content
478 Note: SELinux often uses regular expressions to specify labels that
480 match multiple files.
481 The following file types are defined for init:
483 init_exec_t
487 - Set files with the init_exec_t type, if you want to transition an
489 executable to the init_t domain.
490 Paths:
493 /sbin/init(ng)?, /usr/sbin/init(ng)?, /usr/lib/systemd/[^/]*,
494 /usr/lib/systemd/system-generators/[^/]*, /bin/systemd,
495 /sbin/upstart, /usr/bin/systemd, /usr/sbin/upstart
496 init_tmp_t
499 - Set files with the init_tmp_t type, if you want to store init tempo‐
501 rary files in the /tmp directories.
502 init_var_lib_t
506 - Set files with the init_var_lib_t type, if you want to store the init
508 files under the /var/lib directory.
509 Paths:
512 /var/lib/systemd(/.*)?, /var/lib/private/systemd(/.*)?
513 init_var_run_t
516 - Set files with the init_var_run_t type, if you want to store the init
518 files under the /run or /var/run directory.
519 initctl_t
523 - Set files with the initctl_t type, if you want to treat the files as
525 initctl data.
526 Paths:
529 /dev/initctl, /var/run/initctl, /var/run/systemd/initctl/fifo
530 initrc_devpts_t
533 - Set files with the initrc_devpts_t type, if you want to treat the
535 files as initrc devpts data.
536 initrc_exec_t
540 - Set files with the initrc_exec_t type, if you want to transition an
542 executable to the initrc_t domain.
543 Paths:
546 /etc/init.d/.*, /etc/rc.d/rc.[^/]+, /etc/rc.d/init.d/.*,
547 /opt/nfast/sbin/init.d-ncipher, /usr/libexec/dcc/stop-.*,
548 /usr/libexec/dcc/start-.*, /usr/lib/systemd/fedora[^/]*,
549 /opt/nfast/scripts/init.d/(.*), /etc/rc.d/rc, /etc/X11/prefdm,
550 /usr/sbin/startx, /usr/bin/sepg_ctl, /usr/sbin/apachectl,
551 /usr/sbin/start-dirsrv, /usr/sbin/open_init_pty,
552 /usr/sbin/restart-dirsrv, /etc/sysconfig/network-scripts/ifup-
553 ipsec, /usr/share/system-config-services/system-config-services-
554 mechanism.py
555 initrc_state_t
558 - Set files with the initrc_state_t type, if you want to treat the
560 files as initrc state data.
561 initrc_tmp_t
565 - Set files with the initrc_tmp_t type, if you want to store initrc
567 temporary files in the /tmp directories.
568 initrc_var_log_t
572 - Set files with the initrc_var_log_t type, if you want to treat the
574 data as initrc var log data, usually stored under the /var/log direc‐
575 tory.
576 initrc_var_run_t
580 - Set files with the initrc_var_run_t type, if you want to store the
582 initrc files under the /run or /var/run directory.
583 Paths:
586 /var/run/utmp, /var/run/random-seed, /var/run/runlevel.dir,
587 /var/run/setmixer_flag
588 Note: File context can be temporarily modified with the chcon command.
591 If you want to permanently change the file context you need to use the
592 semanage fcontext command. This will modify the SELinux labeling data‐
593 base. You will need to use restorecon to apply the labels.
594
597 semanage fcontext can also be used to manipulate default file context
598 mappings.
599 semanage permissive can also be used to manipulate whether or not a
601 process type is permissive.
602 semanage module can also be used to enable/disable/install/remove pol‐
604 icy modules.
605 semanage boolean can also be used to manipulate the booleans
607 system-config-selinux is a GUI tool available to customize SELinux pol‐
610 icy settings.
