Show HN: Ferki-Escalator 1.1 – now without libcap

I built this tool to explore Linux capabilities and privilege escalation vectors. In version 1.1, I’ve achieved a major personal goal: completely removing the libcap dependency. To keep the tool truly standalone and portable, I replaced the library with a custom implementation using native Linux syscalls (capget/capset). My core philosophy is "zero-bloat": no malloc (everything is stack-based or static to ensure stability), zero external dependencies, and a minimal footprint. Every byte in the binary must be justified. The backstory: due to limited hardware access, I developed and debugged this entire update directly on my smartphone. This constraint forced me to be a more disciplined architect, ensuring the code is as efficient as possible. It now compiles and runs out-of-the-box on x86, ARM, and other architectures without needing any extra system headers. I hope you find it useful for your audits or learning—whatever your goals may be
