SUNRPC xid


RPC xid initialization and sequencing started the fuss

State Of The Art in 1996:

    call_msg.rm_xid = getpid() ^ now.tv_sec ^ now.tv_usec;

    ...

    ((struct rpc_msg *)clp->mashl_callmsg)->rm_xid ++ ;

oh wait... the FreeBSD tree as of today:

    #define __RPC_GETXID(now) ((u_int32_t)getpid() ^
         (u_int32_t)(now)->tv_sec ^ (u_int32_t)(now)->tv_usec)

    ...

    xid++;
