✨ clogd_selinux ✨

okay bestie, gather round because we're about to get into clogd_selinux — it's the SELinux policy page for the clogd processes and honestly it's giving secure-and-iconic 💅

🌸 NAME 🌸

clogd_selinux — the Security Enhanced Linux Policy for the clogd processes, periodt.

🦋 DESCRIPTION 🦋

Security-Enhanced Linux is literally the bodyguard for the clogd processes, keeping them secure via flexible mandatory access control. no cap, it's the main character of access control 💖

The clogd processes execute with the clogd_t SELinux type. You can vibe check whether you've got these processes running by executing the ps command with the -Z qualifier. slay.

For example:

ps -eZ | grep clogd_t

🎀 ENTRYPOINTS 🎀

The clogd_t SELinux type can be entered via the clogd_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/bin/clogd

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. iconic behavior fr fr.

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 clogd policy is very flexible, allowing users to set up their clogd processes in as secure a method as possible. we love a flexible icon 💅

The following process types are defined for clogd:

clogd_t
Note: semanage permissive -a clogd_t can be used to make the process type clogd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so it's like, chill mode but the receipts are still being kept 📝

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. The clogd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run clogd with the tightest access possible. tightest access = the vibe check we deserve ✨

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 clogd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note that the process's UID still needs to have DAC permissions — SELinux isn't out here doing your DAC's homework for you, bestie 🫶

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. it's like every file needs its own little 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 clogd policy is very flexible, allowing users to set up their clogd processes in as secure a method as possible. yes we're saying it again because it's true and it slaps 💅

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for clogd. 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. like, relabeling but make it a whole ritual 🎀

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

The following file types are defined for clogd:

  • clogd_exec_t — Set files with the clogd_exec_t type if you want to transition an executable to the clogd_t domain. it's the glow-up pipeline ✨
  • clogd_tmpfs_t — Set files with the clogd_tmpfs_t type if you want to store clogd files on a tmpfs file system. temporary but make it labeled 🦋
  • clogd_var_run_t — Set files with the clogd_var_run_t type if you want to store the clogd files under the /run or /var/run directory. runtime realness 💫
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 quick fix and semanage fcontext + restorecon is the committed relationship, iykyk 💍

🔥 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. point-and-click era 🖱️✨
