okay bestie, welcome to user_dbusd_selinux(8) — the SELinux policy page for user_dbusd (SELinux Policy user_dbusd energy, no cap 💅). We're keeping every path, command, boolean, caveat, and reference, but making it cute. 🫶

✨ NAME ✨

user_dbusd_selinux — Security Enhanced Linux Policy for the user_dbusd processes. 🎀

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the user_dbusd processes via flexible mandatory access control. Slay. 🔥

The user_dbusd processes execute with the user_dbusd_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 user_dbusd_t

🚪 ENTRYPOINTS 🚪

The user_dbusd_t SELinux type can be entered via the dbusd_exec_t file type.

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

  • /usr/bin/dbus-daemon(-1)?
  • /usr/bin/dbus-broker
  • /usr/bin/dbus-broker-launch
  • /lib/dbus-1/dbus-daemon-launch-helper
  • /usr/lib/dbus-1/dbus-daemon-launch-helper
  • /usr/libexec/dbus-1/dbus-daemon-launch-helper

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. Main character behavior, honestly. 💅

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

Policy governs the access confined processes have to files. SELinux user_dbusd policy is very flexible allowing users to setup their user_dbusd processes in as secure a method as possible.

The following process types are defined for user_dbusd:

  • user_dbusd_t
Note, bestie: semanage permissive -a user_dbusd_t can be used to make the process type user_dbusd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. 👀

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. user_dbusd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run user_dbusd with the tightest access possible. We love tight access, periodt. ✨

  • fips_mode — If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. Run setsebool -P fips_mode 1.
  • nis_enabled — If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. Run setsebool -P nis_enabled 1.

🗂️ MANAGED FILES 🗂️

The SELinux process type user_dbusd_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. Important little detail, 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.
