Auto-port 4.1: Kqueue: Fix usage of LOCAL_PEERPID#16646
Merged
Conversation
Motivation: SOCK_STREAM (value 1) was being passed as the socket option level, but LOCAL_PEERPID is a Unix domain socket option that lives under SOL_LOCAL. Using SOCK_STREAM as the level would cause getsockopt to look in the wrong protocol layer — on most kernels this silently returns EOPNOTSUPP or wrong data rather than a hard error, so it was easy to miss. Modifications: - Replace SOCK_STREAM with SOL_LOCAL Result: LOCAL_PEERPID works as expected on MacOS / BSD (cherry picked from commit e0ca1e1)
