πŸ’… snapper_grub_plugin_selinux β€” bestie edition

okay so this is the snapper..._selinux(8) page, and honestly? it's giving "niche but essential." we're talking about the SELinux policy for the snapper_grub_plugin processes. sit down, grab a strawberry drink πŸ“, and let's get into it.


✨ NAME ✨

snapper_grub_plugin_selinux β€” the Security Enhanced Linux Policy for the snapper_grub_plugin processes πŸŽ€

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the snapper_grub_plugin processes via flexible mandatory access control. no cap, that's the whole vibe. πŸ”₯

So here's the tea: the snapper_grub_plugin processes execute with the snapper_grub_plugin_t SELinux type. and you can literally check if you have these processes running by executing the ps command with the -Z qualifier.

for example:

ps -eZ | grep snapper_grub_plugin_t

like, go check bestie, i'll wait πŸ’…

πŸ¦‹ ENTRYPOINTS πŸ¦‹

The snapper_grub_plugin_t SELinux type can be entered via the snapper_grub_plugin_exec_t file type. that's the doorway, okay?

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

/usr/lib/snapper/plugins/(00-)?grub

periodt. that's the path. 🎯

πŸ‘‘ PROCESS TYPES πŸ‘‘

SELinux defines process types (domains) for each process running on the system. yes, each one. it's a lot but it's iconic.

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 snapper_grub_plugin policy is very flexible, allowing users to setup their snapper_grub_plugin processes in as secure a method as possible. highkey thoughtful of it.

The following process types are defined for snapper_grub_plugin:

snapper_grub_plugin_t

Note: semanage permissive -a snapper_grub_plugin_t can be used to make the process type snapper_grub_plugin_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 πŸ‘€

🧚 BOOLEANS 🧚

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

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

slay. πŸ’–

🌈 MANAGED FILES 🌈

The SELinux process type snapper_grub_plugin_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 doing everything for you, bestie, you still gotta have the perms. 😭

snapperd_data_t

/mnt/(.*/)?.snapshots(/.*)?
/.snapshots(/.*)?
/etc/.snapshots(/.*)?
/opt/.snapshots(/.*)?
/usr/.snapshots(/.*)?
/var/.snapshots(/.*)?
/home/.snapshots(/.*)?
/home/(.*/)?.snapshots(/.*)?

unlabeled_t

that one's just sitting there with no paths listed. mysterious. we love a quiet icon. πŸŽ€

πŸ’œ FILE CONTEXTS πŸ’œ

SELinux requires files to have an extended attribute to define the file type. it's the file's whole identity, honestly.

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 snapper_grub_plugin policy is very flexible, allowing users to setup their snapper_grub_plugin processes in as secure a method as possible. (yes we said this already but it bears repeating, it's important πŸ’…)

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the snapper_grub_plugin. so 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. 🫢

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

The following file types are defined for snapper_grub_plugin:

  • snapper_grub_plugin_exec_t β€” Set files with the snapper_grub_plugin_exec_t type, if you want to transition an executable to the snapper_grub_plugin_t domain.
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 is literally the whole plot here πŸ’€

πŸ”₯ COMMANDS πŸ”₯

  • 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 πŸŽ€
