Roughtime: Securing Time with Digital Signatures
When you visit a secure website, it offers you a TLS certificate that asserts its identity. Every certificate has an expiration date, and when it’s passed due, it is no longer valid. The idea is almost as old as the web itself: limiting the lifetime of certificates is meant to reduce the risk in case a TLS server’s secret key is compromised. Certificates aren’t the only cryptographic artifacts tha

Epoll is fundamentally broken 1/2 — Idea of the day
In previous articles we talked about: The history of the Select(2) syscall Select(2) being fundamentally broken This time we'll focus on Linux's select(2) successor - the epoll(2) I/O multiplexing syscall. Epoll is relatively young. It was created by Davide Libenzi in 2002. For comparison: Windows did IOCP in 1994 and FreeBSD's kqueue was introduced in July 2000. Unfortunately, even though epoll i

Announcing Envoy: C++ L7 proxy and communication bus
Today we are incredibly excited to open source Envoy, our high performance C++ distributed proxy and communication bus designed for large service oriented architectures. The project was born out of the belief that: The network should be transparent to applications. When network and application problems do occur it should be easy to determine the source of the problem. Envoy runs on every host and

How TCP backlog works in Linux
When an application puts a socket into LISTEN state using the listen syscall, it needs to specify a backlog for that socket. The backlog is usually described as the limit for the queue of incoming connections. Because of the 3-way handshake used by TCP, an incoming connection goes through an intermediate state SYN RECEIVED before it reaches the ESTABLISHED state and can be returned by the accept s
