follow-up Seems like at least OpenBSD implemented SO_PEERCRED which returns a struct sockpeercred. /* Read using getsockopt() with SOL_SOCKET, SO_PEERCRED */ struct sockpeercred { uid_t uid; /* effective user id */ gid_t gid; /* effective group id */ pid_t pid; }; If not anyone is oppose to this or know some other secret API that provides similar functionality, I can see if I can put together a patch for this very useful API.
