Subject:   A better kernel random() ??
Message-ID:  <01IB84DEEOQM001TG9@ZEUS.ED.RAY.COM>
next in thread | raw e-mail | index | archive | help 
        I need a random (psuedo or otherwise) number generator
        for use in kernel network protocols (collision backoff,
        jitter, etc).  I looked, at libkern/random.c and the
        seed is constant.  

        I am looking for suggestions/algorithims for getting a
        more random sequence of numbers.  The two machines are
        running the same kernel and are timed synced.

        I am thinking that a utility program could be written
        to change this seed value via a kernel memory write
        based on some combination of information, such as
                process id,
                address of a network interface,
                ???

        Should the result of such a computaion have any numeric
        properties:
                number of bits set, oddness, not divisible by a
                single digit prime number, etc?


        Any other, better hopefully, ideas?

thanks,
g
