💖 systemd_system_update_generator_selinux — the syst...linux(8) page, bestie edition 💖

okay so first things first: this is the syst...linux(8) manual page, and the star of the show is systemd_system_update_generator_selinux ✨. yes that's a long name. no we're not shortening it. it's giving very-specific-and-proud 🎀

🌸 NAME 🌸

systemd_system_update_generator_selinux — Security Enhanced Linux Policy for the systemd_system_update_generator processes 🦋

✨ DESCRIPTION ✨

so like, Security-Enhanced Linux secures the systemd_system_update_generator processes via flexible mandatory access control. that's the whole vibe 💅

The systemd_system_update_generator processes execute with the systemd_system_update_generator_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier. for example:

ps -eZ | grep systemd_system_update_generator_t

go off, detective 🔍

🚪 ENTRYPOINTS 🚪

The systemd_system_update_generator_t SELinux type can be entered via the systemd_system_update_generator_exec_t file type. that's the door, that's the entrance, that's the way in 🚪✨

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

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

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every single one. it's very thorough like that 🌈

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_system_update_generator policy is very flexible, allowing users to setup their systemd_system_update_generator processes in as secure a method as possible. lowkey iconic 🫶

The following process types are defined for systemd_system_update_generator:

  • systemd_system_update_generator_t
Note: semanage permissive -a systemd_system_update_generator_t can be used to make the process type systemd_system_update_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 but it's still watching you 👀

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. systemd_system_update_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_system_update_generator with the tightest access possible. tightest access = main character energy 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_system_update_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. don't forget that part bestie, SELinux isn't doing ALL the work 🙈

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. it's the little tag that says "this is what i am" 🏷️

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

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the systemd_system_update_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. relocating? we love a glow-up 💖

semanage fcontext -a -t systemd_system_update_generator_exec_t '/srv/systemd_system_update_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_system_update_generator_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🧚

The following file types are defined for systemd_system_update_generator:

  • systemd_system_update_generator_exec_t
    • Set files with the systemd_system_update_generator_exec_t type, if you want to transition an executable to the systemd_system_update_generator_t domain.
  • systemd_system_update_generator_unit_file_t
    • Set files with the systemd_system_update_generator_unit_file_t type, if you want to treat the files as systemd system update 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, choose wisely 💀

🛠️ 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.
