SYSTEMD_SELINUX_AUTORELABEL_GENERATOR_SELINUX(8)

✨ systemd_selinux_autorelabel_generator_selinux(8) ✨

okay bestie, so this is a page from the SELinux Policy manual family (section 8, system admin girlies only 💅) and it's all about the systemd_selinux_autorelabel_generator processes. it's a lot of _ in one name but we're gonna get through it together, i promise 🫶

💖 NAME 💖

systemd_selinux_autorelabel_generator_selinux — the Security Enhanced Linux policy for the systemd_selinux_autorelabel_generator processes. yes that's the whole name. yes i typed it correctly. no i will not be doing it again without a break 🌸

---

🦋 DESCRIPTION 🦋

so Security-Enhanced Linux secures the systemd_selinux_autorelabel_generator processes via flexible mandatory access control — literally the whole point, it's giving bodyguard energy 👑

the systemd_selinux_autorelabel_generator processes execute with the systemd_selinux_autorelabel_generator_t SELinux type. you can check if you actually have these processes running by executing the ps command with the -Z qualifier, like:

ps -eZ | grep systemd_selinux_autorelabel_generator_t

that's it, that's the vibe check right there 🔍

🌈 ENTRYPOINTS 🌈

the systemd_selinux_autorelabel_generator_t SELinux type can be entered via the systemd_selinux_autorelabel_generator_exec_t file type. think of it as the one doorway in 🚪

the default entrypoint paths for the systemd_selinux_autorelabel_generator_t domain are the following:

/usr/lib/systemd/system-generators/selinux-autorelabel-generator(.sh)?

💜 PROCESS TYPES 💜

so SELinux defines process types (domains) for each process running on the system — every process gets its own little assigned identity, slay 💫

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_selinux_autorelabel_generator policy is very flexible, allowing users to setup their systemd_selinux_autorelabel_generator processes in as secure a method as possible. flexible AND secure, we love range 🎀

the following process types are defined for systemd_selinux_autorelabel_generator:

• systemd_selinux_autorelabel_generator_t

Note: semanage permissive -a systemd_selinux_autorelabel_generator_t can be used to make the process type systemd_selinux_autorelabel_generator_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like… it lets stuff through but still talks about it behind your back 💀

🍓 BOOLEANS 🍓

SELinux policy is customizable based on least access required — minimal, curated, only what she needs 🔥 the systemd_selinux_autorelabel_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_selinux_autorelabel_generator with the tightest access possible.

• 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

both of them already on out of the box, iconic default behaviour tbh 👑

🌸 MANAGED FILES 🌸

the SELinux process type systemd_selinux_autorelabel_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 is not out here doing DAC's job for it, no cap 🙈

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type — it's like a little name tag on every file, obsessed 🏷️

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the systemd_selinux_autorelabel_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, like so:

semanage fcontext -a -t systemd_selinux_autorelabel_generator_exec_t '/srv/systemd_selinux_autorelabel_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_selinux_autorelabel_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_selinux_autorelabel_generator:

• systemd_selinux_autorelabel_generator_exec_t — set files with the systemd_selinux_autorelabel_generator_exec_t type if you want to transition an executable to the systemd_selinux_autorelabel_generator_t domain. it's the glow-up pipeline ✨
• systemd_selinux_autorelabel_generator_unit_file_t — set files with the systemd_selinux_autorelabel_generator_unit_file_t type if you want to treat the files as systemd selinux autorelabel generator unit content. unit content, very main character 💅

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. tl;dr — chcon is a temporary fit check, semanage fcontext is the permanent one, and restorecon is what actually puts it on 🔥

👑 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 whole GUI bestie, for when the terminal is too much 🖱️
