💅 pads_selinux(8) — SELinux Policy pads, bestie edition 💅

okay so this is pads_selinux(8), the SELinux Policy page for pads, and we’re gonna make mandatory access control make sense 💖

🌸 NAME 🌸

pads_selinux — the Security-Enhanced Linux policy for the pads processes, periodt ✨

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the pads processes via flexible mandatory access control — yes bestie, mandatory, not optional 💅

The pads processes execute with the pads_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 pads_t

🦋 ENTRYPOINTS 🦋

The pads_t SELinux type can be entered via the pads_exec_t file type.

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

/usr/bin/pads

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system — it’s giving main character energy for every process, fr fr.

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

The following process types are defined for pads:

pads_t

Note: semanage permissive -a pads_t can be used to make the process type pads_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. The pads policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pads with the tightest access possible — lowkey iconic 🔥

  • daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default. Flip it with setsebool -P daemons_dontaudit_scheduling 1 ✨
  • deny_bluetooth — if you want to deny all system processes and Linux users to use bluetooth wireless technology, you must turn on the deny_bluetooth boolean. Disabled by default. Flip it with setsebool -P deny_bluetooth 1 🦋
  • 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. Flip it with setsebool -P fips_mode 1 💖
  • nscd_use_shm — if you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default. Flip it with setsebool -P nscd_use_shm 1 🌸

🌈 MANAGED FILES 🌈

The SELinux process type pads_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 — no cap, DAC still matters 💅

    • /etc/cluster(/.*)?
  • cluster_var_lib_t

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type.

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

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the pads. 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 pads_exec_t '/srv/pads/content(/.*)?'
restorecon -R -v /srv/mypads_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🙈

The following file types are defined for pads:

  • pads_config_t — Set files with the pads_config_t type, if you want to treat the files as pads configuration data, usually stored under the /etc directory.
    • Paths: /etc/pads.conf, /etc/pads-assets.csv, /etc/pads-ether-codes, /etc/pads-signature-list
  • pads_exec_t — Set files with the pads_exec_t type, if you want to transition an executable to the pads_t domain.
  • pads_initrc_exec_t — Set files with the pads_initrc_exec_t type, if you want to transition an executable to the pads_initrc_t domain.
  • pads_var_run_t — Set files with the pads_var_run_t type, if you want to store the pads files under the /run or /var/run directory.
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. 💀

🫶 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.
