💅 wtmpdbd_selinux — the SELinux glow-up for wtmpdbd (manual page for wtmpdbd_selinux(8), bestie!)

okay so welcome to the group chat where we talk about keeping the wtmpdbd processes safe and sound ✨ this is the SELinux policy manual for wtmpdbd, and yes it's giving very much "trusted bodyguard energy" 🫶 let's get into it!

🌸 NAME 🌸

wtmpdbd_selinux — the Security Enhanced Linux Policy for the wtmpdbd processes, periodt 💅

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the wtmpdbd processes via flexible mandatory access control. no cap, that's the whole vibe — SELinux is literally the main character making sure these processes stay in their lane 🔥

The wtmpdbd processes execute with the wtmpdbd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. bestie, -Z is your bestie here, iykyk 👑

For example:

ps -eZ | grep wtmpdbd_t

🎀 ENTRYPOINTS 🎀

The wtmpdbd_t SELinux type can be entered via the wtmpdbd_exec_t file type. that's the doorway, the portal, the entrance if you will 🚪✨

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

/usr/libexec/wtmpdbd

💖 PROCESS TYPES 💖

SELinux defines process types (domains) for each process running on the system — so every process gets its own little personality type, and honestly? iconic 🌈

You can see the context of a process using the -Z option to ps. yes, -Z again, she's everywhere and we love her 💅

Policy governs the access confined processes have to files. SELinux wtmpdbd policy is very flexible allowing users to setup their wtmpdbd processes in as secure a method as possible. flexible but firm — like a good friend who lets you be yourself but also tells you when you're being messy 💜

The following process types are defined for wtmpdbd:

  • wtmpdbd_t
Note: semanage permissive -a wtmpdbd_t can be used to make the process type wtmpdbd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it won't block the process but it WILL still be like "noted 📝" and log everything. lowkey snitch behavior but make it security ✨

🦋 BOOLEANS 🦋

SELinux policy is customizable based on least access required. wtmpdbd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run wtmpdbd with the tightest access possible. the way this is so customizable?? obsessed 😭

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default. so it's already on, slay 🎀

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. also already chillin' in the on position, we love a default ✨

setsebool -P fips_mode 1

👑 MANAGED FILES 👑

The SELinux process type wtmpdbd_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, DAC still has a seat at the table 🙈

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. so like every file has a whole vibe check built in, ngl that's kind of extra but also very secure 💅

You can see the context of a file using the -Z option to ls. -Z again!! she's the moment, she's the icon, she's the legend 👑

Policy governs the access confined processes have to these files. SELinux wtmpdbd policy is very flexible allowing users to setup their wtmpdbd processes in as secure a method as possible. flexibility + security = the dream combo fr fr 🫶

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the wtmpdbd, 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.

semanage fcontext -a -t wtmpdbd_exec_t '/srv/wtmpdbd/content(/.*)?'
restorecon -R -v /srv/mywtmpdbd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex said "i can match MORE than one file actually, watch this" ✨

The following file types are defined for wtmpdbd:

wtmpdbd_exec_t

  • Set files with the wtmpdbd_exec_t type, if you want to transition an executable to the wtmpdbd_t domain. it's giving "executable glow-up journey" 🔥

wtmpdbd_var_run_t

  • Set files with the wtmpdbd_var_run_t type, if you want to store the wtmpdbd files under the /run or /var/run directory. run directory 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 a quick fix, semanage fcontext is the whole makeover, and restorecon is the final reveal 👑🧖‍♀️

⭐ COMMANDS ⭐

semanage fcontext can also be used to manipulate default file context mappings. one tool, many talents 💅

semanage permissive can also be used to manipulate whether or not a process type is permissive. letting processes be a little more chill if you want 😌

semanage module can also be used to enable/disable/install/remove policy modules. modules have entered the chat 🔌

semanage boolean can also be used to manipulate the booleans. the booleans are getting handled, obviously ✨

system-config-selinux is a GUI tool available to customize SELinux policy settings. for the besties who prefer clicking over typing, we see you and we support you 🫶💻
