💖 kafs_selinux(8) — the SELinux tea for kafs 💖

okay so this is the kafs_selinux page from the SELinux Policy kafs manual, section 8, and bestie it's literally all about how SELinux babysits the kafs processes. grab a boba, we're getting into it 🧋✨

---

🌸 NAME 🌸

kafs_selinux — the Security Enhanced Linux Policy for the kafs processes, no cap 🫶

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the kafs processes via flexible mandatory access control. that's the whole vibe — SELinux is the main character keeping kafs in check 💅

The kafs processes execute with the kafs_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier, easy.

For example:

ps -eZ | grep kafs_t

that's it, that's the vibe check 🔍

---

🚪 ENTRYPOINTS 🚪

The kafs_t SELinux type can be entered via the kafs_exec_t file type. so that's the door, iykyk 🚪✨

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

/usr/libexec/kafs-dns

that's the one and only path on the list, periodt 💅

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every single one gets its own little domain, iconic.

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

Policy governs the access confined processes have to files. SELinux kafs policy is very flexible allowing users to setup their kafs processes in as secure a method as possible. flexible and secure, we love a multitalented queen 🌈

The following process types are defined for kafs:

kafs_t

Note: semanage permissive -a kafs_t can be used to make the process type kafs_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like... it stops blocking stuff but it still writes down everything you did in its little diary 📓💀

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. kafs policy is extremely flexible and has several booleans that allow you to manipulate the policy and run kafs with the tightest access possible. tightest access possible = locked down, no crumbs left behind 🍓

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. yes bestie, it's already on 💅

setsebool -P fips_mode 1

---

🦋 FILE CONTEXTS 🦋

SELinux requires files to have an extended attribute to define the file type. every file's gotta have its little name tag, fr fr 🏷️

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 kafs policy is very flexible allowing users to setup their kafs processes in as secure a method as possible. same energy as before, still slaying ✨

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the kafs, 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. relabel era 🎀

semanage fcontext -a -t kafs_exec_t '/srv/kafs/content(/.*)?'
restorecon -R -v /srv/mykafs_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🙈

The following file types are defined for kafs:

kafs_exec_t

• Set files with the kafs_exec_t type, if you want to transition an executable to the kafs_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. so like, chcon is the quick lil temp fix and semanage fcontext + restorecon is the committed relationship 💍

---

🧚 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. a whole GUI, for the visual learners 👑✨
