✨ setfiles_selinux(8) ✨

Okay bestie, so this is the manual page for setfiles_selinux — it's giving "SELinux policy for the setfiles processes" and honestly? It's iconic. Let me walk you through it 💅

---

🌸 NAME 🌸

setfiles_selinux — Security Enhanced Linux Policy for the setfiles processes

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the setfiles processes via flexible mandatory access control. No cap, it's literally out here protecting your system with vibes and rules.

The setfiles processes execute with the setfiles_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 setfiles_t

Periodt. That's the vibe check right there 💖

---

🎀 ENTRYPOINTS 🎀

The setfiles_t SELinux type can be entered via the setfiles_exec_t file type.

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

/usr/bin/setfiles.*, /usr/bin/restorecon

So like, if you see those paths, that's where the magic happens bestie ✨

---

💅 PROCESS TYPES 💅

SELinux defines process types (domains) for each process running on the system.

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

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

The following process types are defined for setfiles:

setfiles_t, setfiles_mac_t

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

Basically, if you want to vibe with permissive mode, you can, but you still get the receipts (AVC messages). Iykyk 🔥

---

🌈 BOOLEANS 🌈

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

If you want to allow system cron jobs to relabel filesystem for restoring file contexts, you must turn on the cron_can_relabel boolean. Disabled by default.

setsebool -P cron_can_relabel 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 enable polyinstantiated directory support, you must turn on the polyinstantiation_enabled boolean. Disabled by default.

setsebool -P polyinstantiation_enabled 1

Slay. Now you can toggle these booleans like a pro 💅✨

---

🧚 MANAGED FILES 🧚

The SELinux process type setfiles_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.

• security_t
  • /selinux
• user_home_type
  • all user home files

So like, it's lowkey managing your security stuff and your home files. Main character energy, honestly 👑

---

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type.

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the setfiles. If you wanted to store files with these types in a different path, 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 setfiles_exec_t '/srv/setfiles/content(/.*)?'
restorecon -R -v /srv/mysetfiles_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for setfiles:

• setfiles_exec_t — Set files with the setfiles_exec_t type, if you want to transition an executable to the setfiles_t domain.

Paths:

• /usr/bin/setfiles.*, /usr/bin/restorecon

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.

No cap, this is important. Temporary changes are cute but permanent changes need the big guns 💅

---

🫶 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.

So like, you've got options, bestie. CLI or GUI, your choice ✨
