✨ system...selinux(8) — the systemd_fstab_generator SELinux page, but make it make sense ✨

okay bestie, this is the manual page for systemd_fstab_generator_selinux — which is a long name but like, it's the security policy page for the systemd_fstab_generator processes 💅. Sit down, hydrate, and let's go.

🌸 NAME 🌸

systemd_fstab_generator_selinux — the Security Enhanced Linux Policy for the systemd_fstab_generator processes. That's it, that's the whole vibe. 🎀

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the systemd_fstab_generator processes via flexible mandatory access control. Like, it's giving "bouncer at the club but for syscalls" ✨.

The systemd_fstab_generator processes execute with the systemd_fstab_generator_t SELinux type. Want to check if you've got these processes running? Run the ps command with the -Z qualifier. Obsessed with a one-liner, honestly:

ps -eZ | grep systemd_fstab_generator_t

👑 ENTRYPOINTS 👑

The systemd_fstab_generator_t SELinux type can be entered via the systemd_fstab_generator_exec_t file type. That's the door, okay? Walk in through the door. 🚪

The default entrypoint paths for the systemd_fstab_generator_t domain are, and I quote:

/usr/lib/systemd/system-generators/systemd-fstab-generator

💖 PROCESS TYPES 💖

SELinux defines process types (domains) for each process running on the system. Main character energy for every single process, lowkey.

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 systemd_fstab_generator policy is very flexible, allowing users to setup their systemd_fstab_generator processes in as secure a method as possible. Flexible and secure? We love a multitasker. 🫶

The following process types are defined for systemd_fstab_generator:

• systemd_fstab_generator_t

Note: semanage permissive -a systemd_fstab_generator_t can be used to make the process type systemd_fstab_generator_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's chill about the denial but it will still gossip about you in the logs. 💀

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. The systemd_fstab_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_fstab_generator with the tightest access possible. Tightest access possible = the friendship boundary of security settings, fr fr.

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 systemd_fstab_generator_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions. SELinux said "I did my part, the UID is your problem now" 😭.

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. Every file needs its little label, and honestly same, I love a name tag. 🏷️

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the systemd_fstab_generator. If you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. Two steps, no skipping, that's the rule 💅:

semanage fcontext -a -t systemd_fstab_generator_exec_t
'/srv/systemd_fstab_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_fstab_generator_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 systemd_fstab_generator:

• systemd_fstab_generator_exec_t — Set files with the systemd_fstab_generator_exec_t type, if you want to transition an executable to the systemd_fstab_generator_t domain.
• systemd_fstab_generator_unit_file_t — Set files with the systemd_fstab_generator_unit_file_t type, if you want to treat the files as systemd fstab generator 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. Temporary vs permanent — know the difference or cry about it 🫶

💅 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 GUI! For the girlies who like buttons 🎀
