Modified files:
sys/sys random.h
sys/dev/randomdev randomdev.c yarrow.c
Log:
Add randomness write functionality. This does absolutely nothing for
entropy estimation, but causes an immediate reseed after the input
(read in sizeof(u_int64_t) chunks) is "harvested".
This will be used in the reboot "reseeder", coming in another
commit. This can be used very effectively at any time you think
your randomness is compromised; something like
# (ps -gauxwww; netstat -an; dmesg; vmstat -c10 1) > /dev/random
will give the attacker something to think about.
