I have a small update to my proposal for an ABI, that should be easier to deploy if the ABI gods can't find fault with it. #define SOCK_FDNS 0x100000 /* Some good non-conflicting number */ And then reuse extend socket to read one more argument when it is passed. So. asmlinkage long sys_socket(int domain, int type, int protocol); becomes: asmlinkage long sys_socket(int domain, int type, int protocol, int fd); when SOCK_FDNS is set in type. I believe the calling conventions in the kernel already pass 4 arguments so we just need to read and act on the forth. That should be easier than allocating an extra syscall number on every architecture.
