πŸ’– NAME πŸ’–

restorecond_selinux(8) β€” the Security Enhanced Linux Policy page for the restorecond processes. Bestie, this is the SELinux glow-up guide for restorecond, no cap. πŸ’…


✨ DESCRIPTION ✨

Security-Enhanced Linux secures the restorecond processes via flexible mandatory access control. It’s giving tight security with main character energy. πŸ‘‘

The restorecond processes execute with the restorecond_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep restorecond_t

πŸšͺ ENTRYPOINTS πŸšͺ

The restorecond_t SELinux type can be entered via the restorecond_exec_t file type. That’s the doorway, bestie. 🫢

The default entrypoint paths for the restorecond_t domain are the following:

  • /usr/bin/restorecond

🧬 PROCESS TYPES 🧬

SELinux defines process types (domains) for each process running on the system. Yes, every process gets a little identity check. πŸ’«

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux restorecond policy is very flexible, allowing users to set up their restorecond processes in as secure a method as possible. Iconic behavior, honestly.

The following process types are defined for restorecond:

  • restorecond_t
Note: semanage permissive -a restorecond_t can be used to make the process type restorecond_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So it’s not a β€œno rules” pass, it’s more like β€œwe see you, but we’re not blocking you.” πŸ‘€

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. restorecond policy is extremely flexible and has several booleans that allow you to manipulate the policy and run restorecond with the tightest access possible. Little switches, big security vibes. πŸŽ€

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

πŸ“‚ MANAGED FILES πŸ“‚

The SELinux process type restorecond_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions. Slay, but permissions still matter. πŸ’…

  • cluster_conf_t β€” default paths:
    • /etc/cluster(/.*)?
  • cluster_var_lib_t β€” default paths:
    • /var/lib/pcsd(/.*)?
    • /var/lib/cluster(/.*)?
    • /var/lib/openais(/.*)?
    • /var/lib/pengine(/.*)?
    • /var/lib/corosync(/.*)?
    • /usr/lib/heartbeat(/.*)?
    • /var/lib/heartbeat(/.*)?
    • /var/lib/pacemaker(/.*)?

    • /run/rsctmp(/.*)?
    • /run/aisexec.*
    • /run/heartbeat(/.*)?

    • /run/cpglockd.pid
    • /run/rgmanager.pid
    • /run/cluster/rgmanager.sk
  • krb5_host_rcache_t β€” default paths:
    • /var/tmp/krb5_0.rcache2
    • /var/cache/krb5rcache(/.*)?
    • /var/tmp/nfs_0
    • /var/tmp/DNS_25

    • /var/tmp/HTTP_48
    • /var/tmp/ldap_55
    • /var/tmp/ldap_487
    • /var/tmp/ldapmap1_0
  • root_t β€” default paths:
    • /sysroot/.aleph-version.json
    • /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
    • /
    • /initrd
    • /var/lib/ntp

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. It’s literally the file’s little label era. ✨

You can see the context of a file using the -Z option to ls.

Policy governs the access confined processes have to these files. SELinux restorecond policy is very flexible, allowing users to set up their restorecond processes in as secure a method as possible. Security but make it customizable. πŸ¦‹

πŸŽ€ STANDARD FILE CONTEXT πŸŽ€

SELinux defines the file context types for restorecond. If you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t restorecond_exec_t
'/srv/restorecond/content(/.*)?'
restorecon -R -v /srv/myrestorecond_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for restorecond:

  • restorecond_exec_t
    • Set files with the restorecond_exec_t type if you want to transition an executable to the restorecond_t domain.
  • restorecond_var_run_t
    • Set files with the restorecond_var_run_t type if you want to store the restorecond files under the /run or /var/run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. Permanent means permanent, bestie. 🫢

πŸ› οΈ COMMANDS πŸ› οΈ

  • semanage fcontext can also be used to manipulate default file context mappings.
  • semanage permissive can also be used to manipulate whether or not a process type is permissive.
  • semanage module can also be used to enable/disable/install/remove policy modules.
  • semanage boolean can also be used to manipulate the booleans.
  • system-config-selinux is a GUI tool available to customize SELinux policy settings.
