Of course it's a concurrency bug. It races sending data to the kernel against the kernel sending data to the network. If the wrong one wins the bug occurs.

But it did not take 2 threads within the same application to interact in a bad way on data the system controlled to cause this problem.

This reads more like an overly broad transition in a deterministic state machine. The fix was to split up a bad transition to shutdown.

Isn't that like saying there can never be a language with safe concurrency since the code could interact with C code that segfaults? I dunno this kinda reminds me of the 10/10 Rust CVE that turned out to be cmd.exe on Windows not sanitizing inputs and languages like Java just labeled it "won't fix".

  • You mean the one where Windows doesn't have argv the way Unix does, and instead just has a single string that is interpreted slightly differently by each executable? That is a language making false assertions about how the underlying platform works, causing an impedance mismatch that is impossible to fix.
