Module local 

Local Socket Implementation

This module implements local (Unix-like) domain sockets for inter-process communication through named socket paths in the filesystem namespace.

Design

• Named Sockets: Sockets can be bound to filesystem paths
• Connection Oriented: Uses stream sockets for reliable, ordered data transfer
• NetworkManager Integration: Uses global NetworkManager for socket registry
• Direct Buffer Management: Uses VecDeque for efficient data queuing

Socket States

1. Unconnected: Initial state after creation
2. Bound: Socket bound to a local address
3. Listening: Server socket accepting connections
4. Connected: Client socket or accepted connection

Macros

Local Socket Implementation

SocketBuffer 🔒

Shared buffer structure for socket data

Constants

LOCALSOCKET_LOG 🔒

MAX_BUFFER_SIZE 🔒

Maximum buffer size per socket (64 KB)

MAX_HANDLE_QUEUE_SIZE 🔒

Maximum number of handles that can be queued for transfer This prevents unbounded memory growth from DoS attacks
