    crypto: ansi_cprng - Allow resetting of DT value · 2566578a
    Neil Horman authored
    	This is a patch that was sent to me by Jarod Wilson, marking off my
    outstanding todo to allow the ansi cprng to set/reset the DT counter value in a
    cprng instance.  Currently crytpo_rng_reset accepts a seed byte array which is
    interpreted by the ansi_cprng as a {V key} tuple.  This patch extends that tuple
    to now be {V key DT}, with DT an optional value during reset.  This patch also
    fixes  a bug we noticed in which the offset of the key area of the seed is
    started at DEFAULT_PRNG_KSZ rather than DEFAULT_BLK_SZ as it should be.
