💖 kpropd_selinux(8) — the manual page, but make it cute 💖

Hey bestie! 🌸 This is the kpropd_selinux manpage, section 8 of the manual. It's giving SELinux policy for kpropd processes, and it's lowkey iconic. No cap, let's get into it. 🫶

✨ NAME ✨

kpropd_selinux — Security-Enhanced Linux policy for the kpropd processes. That's the whole vibe. 💅

🌈 DESCRIPTION 🌈

Okay so, Security-Enhanced Linux secures the kpropd processes via flexible mandatory access control. Fr fr.

The kpropd processes execute with the kpropd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. It's giving "who dis?" energy.

For example:

ps -eZ | grep kpropd_t

🦋 ENTRYPOINTS 🦋

The kpropd_t SELinux type can be entered via the kpropd_exec_t file type. Main character entry point energy, honestly.

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

/usr/bin/kpropd, /usr/bin/_kpropd, /usr/kerberos/sbin/kpropd

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. It's giving organized. 🎀

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

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

The following process types are defined for kpropd:

kpropd_t
Note: semanage permissive -a kpropd_t can be used to make the process type kpropd_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 still snitches. 🙈

💜 BOOLEANS 💜

SELinux policy is customizable based on least access required. kpropd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run kpropd with the tightest access possible. Bestie, it's giving options. ✨

  • 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
  • If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1

🍓 PORT TYPES 🍓

SELinux defines port types to represent TCP and UDP ports. It's giving networking, but make it secure. 💅

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for kpropd:

kprop_port_t

Default Defined Ports:

tcp 754

🧚 MANAGED FILES 🧚

The SELinux process type kpropd_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. Lowkey important, don't skip this part. 🌈

🌸 FILE CONTEXTS 🌸

SELinux requires files to have an extended attribute to define the file type. It's giving metadata realness.

You can see the context of a file using the -Z option to ls. Slay.

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for kpropd. 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. It's giving "customize your look." 💅

semanage fcontext -a -t kpropd_exec_t '/srv/kpropd/content(/.*)?'
restorecon -R -v /srv/mykpropd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. So like, regex is your bestie here. 🫶

The following file types are defined for kpropd:

kpropd_exec_t

  • Set files with the kpropd_exec_t type, if you want to transition an executable to the kpropd_t domain.

Paths:

/usr/bin/kpropd, /usr/bin/_kpropd, /usr/kerberos/sbin/kpropd
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, temporary vs permanent, you know? 🙈

🔥 COMMANDS 🔥

semanage fcontext can also be used to manipulate default file context mappings. It's giving multitasking. 💅

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 port can also be used to manipulate the port definitions.

semanage boolean can also be used to manipulate the booleans.

system-config-selinux is a GUI tool available to customize SELinux policy settings. Graphic design is their passion. 🎨
