okay bestie, this is ktlshd_selinux(8) β€” the SELinux Policy for ktlshd page, and we're gonna get you comfy with it. πŸ’…βœ¨


πŸŽ€ NAME πŸŽ€

ktlshd_selinux β€” Security Enhanced Linux Policy for the ktlshd processes. 🫢

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the ktlshd processes via flexible mandatory access control. No cap, that's the whole vibe.

The ktlshd processes execute with the ktlshd_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 ktlshd_t

πŸ¦‹ ENTRYPOINTS πŸ¦‹

The ktlshd_t SELinux type can be entered via the ktlshd_exec_t file type.

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

/usr/bin/tlshd

πŸ‘‘ PROCESS TYPES πŸ‘‘

SELinux defines process types (domains) for each process running on the system. iconic behavior, honestly.

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

Policy governs the access confined processes have to files. SELinux ktlshd policy is very flexible allowing users to setup their ktlshd processes in as secure a method as possible.

The following process types are defined for ktlshd:

  • ktlshd_t
Note: semanage permissive -a ktlshd_t can be used to make the process type ktlshd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

πŸ“ BOOLEANS πŸ“

SELinux policy is customizable based on least access required. ktlshd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ktlshd with the tightest access possible.

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

🌈 MANAGED FILES 🌈

The SELinux process type ktlshd_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.

  • cluster_conf_t
    • /etc/cluster(/.*)?
  • cluster_var_lib_t
    • /var/lib/pcsd(/.*)?
    • /var/lib/cluster(/.*)?
    • /var/lib/openais(/.*)?
    • /var/lib/pengine(/.*)?
    • /var/lib/corosync(/.*)?
    • /usr/lib/heartbeat(/.*)?
    • /var/lib/heartbeat(/.*)?

    • /
    • /initrd
    • /var/lib/ntp

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. it's giving "labels are everything."

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 ktlshd policy is very flexible allowing users to setup their ktlshd processes in as secure a method as possible.

✨ STANDARD FILE CONTEXT ✨

SELinux defines the file context types for the ktlshd, if you wanted to store files with these types in a 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 ktlshd_exec_t '/srv/ktlshd/content(/.*)?'
restorecon -R -v /srv/myktlshd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for ktlshd:

  • ktlshd_exec_t β€” Set files with the ktlshd_exec_t type, if you want to transition an executable to the ktlshd_t domain.
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.

🌟 COMMANDS 🌟

  • 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.
