Ahmed Elaidy

Systems programmer. I work in C on Linux internals, mostly on CRIU, which freezes running processes to disk and brings them back later.

Selected work

2026 Socket credentials and pidfds in CRIU
Google Summer of Code 2026. Taught CRIU to checkpoint and restore the identity the kernel attaches to Unix socket messages, including the case where the sender is already dead.
2026 Upstream CRIU fixes and features
Seventeen merged patches before the summer: per-thread timer slack, pipe ownership on restore, and a handful of correctness fixes in the image writer and the Unix socket code.

Writing

Aug 2026 Checkpointing a message from a process that no longer exists
How I taught CRIU to checkpoint and restore socket credentials and pidfds, including the case where the sender is already dead. Google Summer of Code 2026.
