🌸 system...elinux(8) — the systemd_growpart_generator SELinux policy page 🌸

Hiii bestie 💖 okay so this is page 8 of the system...elinux manual, and it's all about the SELinux policy for the systemd_growpart_generator processes. Yes the title is literally system...elinux(8), we don't question the naming choices of the man page gods, we just vibe with it ✨

💅 NAME

systemd_growpart_generator_selinux — Security Enhanced Linux Policy for the systemd_growpart_generator processes. That's it, that's the whole thing, and honestly? iconic.

---

🦋 DESCRIPTION

Security-Enhanced Linux secures the systemd_growpart_generator processes via flexible mandatory access control. No cap, that's the whole flex of SELinux — it's out here doing mandatory access control and it's flexible about it 💁‍♀️

The systemd_growpart_generator processes execute with the systemd_growpart_generator_t SELinux type. Wanna check if you actually have these processes running? Run the ps command with the -Z qualifier, like this:

ps -eZ | grep systemd_growpart_generator_t

That's it. That's the whole vibe check 👑

---

🎀 ENTRYPOINTS

The systemd_growpart_generator_t SELinux type can be entered via the systemd_growpart_generator_exec_t file type. Slay 💅

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

/usr/lib/systemd/system-generators/growpart-generator.sh

---

✨ PROCESS TYPES

SELinux defines process types (domains) for each process running on the system. Lowkey the whole system is just domains in a trench coat.

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

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

The following process types are defined for systemd_growpart_generator:

systemd_growpart_generator_t

Note: semanage permissive -a systemd_growpart_generator_t can be used to make the process type systemd_growpart_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 not a free pass, it's just a "we're still watching you" pass 👀

---

🌈 BOOLEANS

SELinux policy is customizable based on least access required. systemd_growpart_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_growpart_generator with the tightest access possible. Tightest access possible = main character energy, honestly 💜

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_growpart_generator_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 out here overriding your uid, bestie, they're coworkers 🤝

🧚 FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type. It's giving "your file has a whole personality attached to it" 💅

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

⭐ STANDARD FILE CONTEXT

SELinux defines the file context types for the systemd_growpart_generator. 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. Two steps, no shortcuts, periodt ✨

semanage fcontext -a -t systemd_growpart_generator_exec_t '/srv/systemd_growpart_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_growpart_generator_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Yes regex, in your labels, we love a pattern-matching queen 🌸

The following file types are defined for systemd_growpart_generator:

• systemd_growpart_generator_exec_t — Set files with the systemd_growpart_generator_exec_t type, if you want to transition an executable to the systemd_growpart_generator_t domain.
• systemd_growpart_generator_unit_file_t — Set files with the systemd_growpart_generator_unit_file_t type, if you want to treat the files as systemd growpart 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. So like… chcon is the cute lil temporary tattoo and semanage fcontext + restorecon is the real ink 😭 don't mix them up!!

---

👑 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. For the besties who prefer clicking to typing 💖
