🦀 trust — Userspace TCP/IP Stack

A TCP/IP stack implemented from scratch in Rust, running in userspace on top of a Linux TUN interface.

Instead of relying on the kernel's TCP implementation, the project handles networking logic in userspace.

Implemented

• Packet parsing
• IP processing
• TCP packet handling
• TCP handshake
• TCP connection state machine
• Linux TUN interface integration
• Concurrent connection handling

Results

Packet loss              : 0%
RTT                      : < 2ms
Concurrent SYN probes    : 20
