Bluetooth Manual-Only

Warning

This script is LLM slopcoded. But I read the code and tested all behavior paths that I know of. Read the code first and use at your own risk.

Keep selected Bluetooth devices paired and visible in GNOME while preventing them from reconnecting to the computer.

Appplies untrust to devices to prevent computer → device reconnection (re-applied on startup and device disconnect)
AuthorizeService() denial to prevent device → computer reconnection
Device can still be manually reconnected in GNOME Settings or Quick Settings

Proof of concept SECCOMP_RET_USER_NOTIF based Frida syscall tracer

A hacked up version of https://man7.org/tlpi/code/online/dist/seccomp/seccomp_user_notification.c.html running inside Frida.

installFilter() should be called on the main thread of the application. It's not possible to install the seccomp filter from rpc.exports.init() because it runs on a Frida thread.

installFilter() sets NO_NEW_PRIVS (required if non-root), installs the seccomp filter to trigger notifications, then creates a pthread to watch for notifications. Upon notifications a callback into Frida is invoked.

When the callback fires, it won't be on the thread that invoked the syscall. I'm not actually sure how to use Frida interact with the suspended thread. Don't know how to get a backtrace on it or execute code on it. Might be possible to set a temporary interceptor on it's EIP.
