wolfIP – An open-source, lightweight TCP/IP stack with no dynamic memory allocations for embedded systems

wolfip TCP/IP library no memory allocations

Better known for its open-source wolfSSL SSL/TLS library, wolfSSL (the company) has now released the wolfIP open-source, lightweight TCP/IP stack with no dynamic memory allocations (e.g., no malloc calls) designed for resource-constrained embedded systems.

The company highlights that wolfIP “supports both endpoint-only mode and full multi-interface support with optional IP forwarding. By default, it operates as a network endpoint, but can be configured to forward traffic between multiple network interfaces”.

TrustTunnel is an open-source, high-performance VPN protocol that’s harder to detect and block

How TrustTunnerl AdGuard VPN protocol works

Adguard VPN is a commercial VPN solution, but the company has decided to open-source the VPN protocol and named it TrustTunnel. It’s described as a modern, secure, mobile-optimized VPN protocol. Since there are plenty of VPN protocols, including WireGuard and OpenVPN, it felt redundant at first. But AdGuard explains that those are easy to detect and block at the network level, and methods to conceal VPN traffic, such as wrapping VPN data in a TCP connection, often reduce speed. TrustTunnel relies on a different method and blends in with regular HTTPS traffic through TLS-based encryption, and HTTP/2 or HTTP/3 transport. Each connection runs on its own dedicated stream, which combines packets for more efficient transmission. The diagrams above and below illustrate this by showing that four hops are required for a standard concealed VPN, and only two hops with TrustTunnel. The company also says it is optimized for mobile platforms […]
