💅 stalld_selinux — the SELinux glow-up for stalld

okay so bestie, this is the stalld_selinux(8) page (that's the manual, the big sister of stalld fr) and it's literally all about how SELinux — Security Enhanced Linux — keeps the stalld processes in check. Think of it as the group chat rules but for processes. 🎀

---

✨ NAME ✨

stalld_selinux — the Security Enhanced Linux Policy for the stalld processes, no cap.

🌸 DESCRIPTION 🌸

So Security-Enhanced Linux secures the stalld processes via flexible mandatory access control. That's the whole vibe — a bouncer at the door that checks vibes before anything gets to do anything. 💅

The stalld processes execute with the stalld_t SELinux type. You wanna check if you've got these processes running? Just run the ps command with the -Z qualifier, easy.

For example:

ps -eZ | grep stalld_t

🦋 ENTRYPOINTS 🦋

The stalld_t SELinux type can be entered via the stalld_exec_t file type. That's the doorway, the main character entrance, iykyk.

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

/usr/bin/stalld

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. Every process gets a whole personality, literally.

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

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

The following process types are defined for stalld:

stalld_t

Note: semanage permissive -a stalld_t can be used to make the process type stalld_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it stops being strict but it still ✍️ writes down ✍️ everything. 😭

🍓 BOOLEANS 🍓

SELinux policy is customizable based on least access required. The stalld policy is extremely flexible and has several booleans that allow you to manipulate the policy and run stalld with the tightest access possible. Locked down, glowing, iconic. 🔥

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 stalld_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 — SELinux isn't doing ALL the work, bestie. 🙈

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. It's giving... files with receipts. 🧾

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

Policy governs the access confined processes have to these files. The SELinux stalld policy is very flexible, allowing users to setup their stalld processes in as secure a method as possible. We love a flexible icon. ✨

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for the stalld, and 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. Move the file, re-stick the label, slay.

semanage fcontext -a -t stalld_exec_t '/srv/stalld/content(/.*)?'
restorecon -R -v /srv/mystalld_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning. 💅

The following file types are defined for stalld:

• stalld_exec_t — Set files with the stalld_exec_t type, if you want to transition an executable to the stalld_t domain.
• stalld_unit_file_t — Set files with the stalld_unit_file_t type, if you want to treat the files as stalld unit content.
• stalld_var_run_t — Set files with the stalld_var_run_t type, if you want to store the stalld 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. So like — chcon is the temporary tattoo, semanage fcontext is the real one. 😭

⭐ 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. Yes bestie, there's a GUI, you don't have to rawdog the terminal. 🫶
