Neil Horman d7992f42c6 crypto: ansi_cprng - Force reset on allocation
Pseudo RNGs provide predictable outputs based on input parateters {key, V, DT},
the idea behind them is that only the user should know what the inputs are.
While its nice to have default known values for testing purposes, it seems
dangerous to allow the use of those default values without some sort of safety
measure in place, lest an attacker easily guess the output of the cprng.  This
patch forces the NEED_RESET flag on when allocating a cprng context, so that any
user is forced to reseed it before use.  The defaults can still be used for
testing, but this will prevent their inadvertent use, and be more secure.
