💖 NAME 💖

okay so this is the quota_nld_selinux(8) page, bestie — Security Enhanced Linux Policy for the quota_nld processes. that's the whole name vibe. no cap, it's giving mandatory access control but make it fashion ✨

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the quota_nld processes via flexible mandatory access control. iconic behavior, honestly 👑

The quota_nld processes execute with the quota_nld_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 quota_nld_t

🦋 ENTRYPOINTS 🦋

The quota_nld_t SELinux type can be entered via the quota_nld_exec_t file type.

The default entrypoint paths for the quota_nld_t domain are literally the following:

/usr/bin/quota_nld

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. lowkey important, iykyk.

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

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

The following process types are defined for quota_nld:

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

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. quota_nld policy is extremely flexible and has several booleans that allow you to manipulate the policy and run quota_nld with the tightest access possible. fr fr, you can tune this thing.

  • 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

🌈 MANAGED FILES 🌈

The SELinux process type quota_nld_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.

🧚 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. SELinux quota_nld policy is very flexible allowing users to setup their quota_nld processes in as secure a method as possible.

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the quota_nld; 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.

semanage fcontext -a -t quota_nld_exec_t '/srv/quota_nld/content(/.*)?'
restorecon -R -v /srv/myquota_nld_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🫶

The following file types are defined for quota_nld:

  • quota_nld_exec_t — Set files with the quota_nld_exec_t type, if you want to transition an executable to the quota_nld_t domain.
  • quota_nld_var_run_t — Set files with the quota_nld_var_run_t type, if you want to store the quota nld 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. permanent label glow-up only, bestie 💅

🛠️ 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.
