Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Local control connections on the netlink socket could bypass authentication, leading to privilege escalation. This was resolved by implementing a cryptographically secure random token (secret) validation mechanism using os.urandom.
Denial of Service: Process proxies (NSPopen) and child process communication channels repeatedly leaked pipe file descriptors, sentinels, and queues upon termination, causing system-wide resource exhaustion. Explicit resource cleanup and child joining were implemented to resolve this.
Denial of Service: Failure during NetNS initialization or garbage collection left transport channels, communication pipes, and atexit handlers open. The fix introduced explicit unregistration and socket-channel closing upon exceptions.
