✨ timedatex_selinux — the SELinux glow-up for your timedatex processes ✨

okay bestie, so this is timedatex_selinux(8), aka the manual page you pull up when you're trying to understand how SELinux handles the timedatex processes 💅

🌸 NAME 🌸

timedatex_selinux — literally the Security Enhanced Linux Policy for the timedatex processes 🫶

🦋 SYNOPSIS 🦋

(this one's a vibe page, no synopsis line to copy, iykyk)

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the timedatex processes via flexible mandatory access control. no cap, that's the whole flex 🔥

The timedatex processes execute with the timedatex_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier ✨

For example:

ps -eZ | grep timedatex_t

🎀 ENTRYPOINTS 🎀

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

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

/usr/sbin/timedatex

🌈 PROCESS TYPES 🌈

SELinux defines process types (domains) for each process running on the system. it's giving very organized 👑

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

Policy governs the access confined processes have to files. SELinux timedatex policy is very flexible allowing users to setup their timedatex processes in as secure a method as possible. maximum security, maximum slay 🔥

The following process types are defined for timedatex:

timedatex_t
💀 Note: semanage permissive -a timedatex_t can be used to make the process type timedatex_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, ngl 👀

🍓 BOOLEANS 🍓

SELinux policy is customizable based on least access required. timedatex policy is extremely flexible and has several booleans that allow you to manipulate the policy and run timedatex with the tightest access possible. it's giving tailored fit 💅

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 timedatex_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. okay so, you still need actual permission permission, this is the extra layer ✨

🌟 FILE CONTEXTS 🌟

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. SELinux timedatex policy is very flexible allowing users to setup their timedatex processes in as secure a method as possible. obsessed with how flexible this is 💅

The following file types are defined for timedatex:

🎀 timedatex_exec_t

  • Set files with the timedatex_exec_t type, if you want to transition an executable to the timedatex_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. so chcon is the quick fix and semanage fcontext + restorecon is the forever commitment, periodt 💍

👑 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 visual learners, we love that 🎀
