CACHEFILES_KERNEL_SELINUX(8)

🧚 cachefiles_kernel_selinux(8) — the SELinux page, but make it cute 🧚

💖 NAME 💖

cachefiles_kernel_selinux — Security Enhanced Linux Policy for the cachefiles_kernel processes.

✨ DESCRIPTION ✨

Okay so Security-Enhanced Linux secures the cachefiles_kernel processes via flexible mandatory access control. That's the whole point, bestie.

The cachefiles_kernel processes execute with the cachefiles_kernel_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 cachefiles_kernel_t

🦋 PROCESS TYPES 🦋

SELinux defines process types (domains) for each process running on the system — yes, every single one.

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 cachefiles_kernel policy is very flexible, allowing users to setup their cachefiles_kernel processes in as secure a method as possible.

The following process types are defined for cachefiles_kernel:

cachefiles_kernel_t

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

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. The cachefiles_kernel policy is extremely flexible and has several booleans that allow you to manipulate the policy and run cachefiles_kernel with the tightest access possible.

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 cachefiles_kernel_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.

• cachefiles_var_t
  • /var/fscache(/.*)?
  • /var/cache/fscache(/.*)?

💅 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.
