Accuracy numbers are starting to feel solid: up to 100% of function entries detected, with less than 1% false positives. Tested on Debian Trixie's grep 3.11-4, compiled with GCC 14.2, CF protection and fully stripped.
Was adding stripped binary support to #xcover with no debug info.
So I started playing with the Go disassembler and pulled the implementation out into #ResurGo: a Go library for prologue detection + call site analysis, supporting x86_64 and ARM64.

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.
