💅 sanlk_resetd_selinux — the whole vibe

okay so bestie, welcome to sanlk_resetd_selinux(8) — this is the SELinux Policy page for the sanlk_resetd processes, and it's fr fr everything you need to know about locking this daemon down (or, like, understanding how it's already locked down). consider this your group-chat explainer ✨

---

🎀 DESCRIPTION

Security-Enhanced Linux secures the sanlk_resetd processes via flexible mandatory access control. yes, that's the whole point — SELinux is the bouncer at the club and it's checking IDs 🫶

The sanlk_resetd processes execute with the sanlk_resetd_t SELinux type. Wanna check if you've got these processes running rn? just run ps with the -Z qualifier, iykyk.

For example:

ps -eZ | grep sanlk_resetd_t

like literally that's it. copy-paste and go 🌸

---

🚪 ENTRYPOINTS

The sanlk_resetd_t SELinux type can be entered via the sanlk_resetd_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/bin/sanlk-resetd

---

👑 PROCESS TYPES

SELinux defines process types (domains) for each process running on the system. every process gets its own little domain, it's giving main character energy for each one 💜

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

The following process types are defined for sanlk_resetd:

sanlk_resetd_t

Note: semanage permissive -a sanlk_resetd_t can be used to make the process type sanlk_resetd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it'll still snitch in the logs, just won't block you 🙈 ngl that's very "I'm not mad, I'm just disappointed" of it.

---

🍓 BOOLEANS

SELinux policy is customizable based on least access required. the sanlk_resetd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sanlk_resetd with the tightest access possible. slay, precision locking-down 💅

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 sanlk_resetd_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and bestie, heads up: the process's UID still needs to have DAC permissions. SELinux ain't overriding that for you 🔥

🦋 FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type. yeah, every file's got a little label on it, it's iconic 🏷️

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 sanlk_resetd policy is very flexible, allowing users to setup their sanlk_resetd processes in as secure a method as possible. (yes we said that twice, it's that flexible 💀)

⭐ STANDARD FILE CONTEXT

SELinux defines the file context types for sanlk_resetd. 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. so it's a two-step, no skipping 🎀

semanage fcontext -a -t sanlk_resetd_exec_t '/srv/sanlk_resetd/content(/.*)?'
restorecon -R -v /srv/mysanlk_resetd_content

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

The following file types are defined for sanlk_resetd:

• sanlk_resetd_exec_t — Set files with the sanlk_resetd_exec_t type, if you want to transition an executable to the sanlk_resetd_t domain. that's the glow-up pipeline ✨
• sanlk_resetd_unit_file_t — Set files with the sanlk_resetd_unit_file_t type, if you want to treat the files as sanlk resetd unit content. 🧚

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 chcon is the cute lil temporary tattoo and semanage fcontext + restorecon is the real ink 🙈

---

🛠️ 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, a whole GUI, for the people who prefer clicking to typing 💅
