💅 NetworkManager_dispatcher_custom_selinux(8) — the whole ~vibe~

okay so bestie, this is the manual page for the SELinux policy that covers the NetworkManager_dispatcher_custom processes. It's in section 8, it's an SELinux policy page, and yes it is exactly as much of a mood as it sounds. Sit down, grab a lil snack 🍓, we're doing this.

✨ NAME ✨

NetworkManager_dispatcher_custom_selinux — Security Enhanced Linux Policy for the NetworkManager_dispatcher_custom processes. That's it. That's the whole name. Slay. 💅

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the NetworkManager_dispatcher_custom processes via flexible mandatory access control. Like, it's out here doing the most so your processes stay contained — iconic behavior honestly.

The NetworkManager_dispatcher_custom processes execute with the NetworkManager_dispatcher_custom_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 NetworkManager_dispatcher_custom_t

literally just pipe it into grep and see what's up. ✨

---

🚪 ENTRYPOINTS 🚪

The NetworkManager_dispatcher_custom_t SELinux type can be entered via the NetworkManager_dispatcher_script_t file type.

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

/etc/NetworkManager/dispatcher.d(/.*)?,
/usr/lib/NetworkManager/dispatcher.d(/.*)?

those are your vip entrances 🎀

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system.

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

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

The following process types are defined for NetworkManager_dispatcher_custom:

• NetworkManager_dispatcher_custom_t

Note: semanage permissive -a NetworkManager_dispatcher_custom_t can be used to make the process type NetworkManager_dispatcher_custom_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like… it's not really off, it's just being nice about it 😭

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. NetworkManager_dispatcher_custom policy is extremely flexible and has several booleans that allow you to manipulate the policy and run NetworkManager_dispatcher_custom with the tightest access possible. customizing your own access level?? main character energy fr fr.

If you want to deny user domains applications to map a memory region as both executable and writable — this is dangerous and the executable should be reported in bugzilla — you must turn on the deny_execmem boolean. Disabled by default.

setsebool -P deny_execmem 1

If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Disabled by default.

setsebool -P secure_mode_insmod 1

If you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla — you must turn on the selinuxuser_execheap boolean. Disabled by default.

setsebool -P selinuxuser_execheap 1

If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla — you must turn on the selinuxuser_execstack boolean. Disabled by default.

setsebool -P selinuxuser_execstack 1

🫶 bestie please clock that: the manpage itself is out here saying "this should never, ever be necessary" and "doing this is a really bad idea". that's not me being dramatic, that's the actual doc. respect the warning. 🙈

📂 MANAGED FILES 📂

The SELinux process type NetworkManager_dispatcher_custom_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. (SELinux said yes, but DAC still gets a vote, iykyk.)

• file_type — all files on the system

---

🛠️ 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. a whole GUI, for the girlies who prefer clicking 💅✨
