random_systat.seeded is exported to sysctl? isn't it?
In this case If somebody resets it to zero, some "read" goest to "block" and
before acquiring mutex it is reseeded, setting it to true, block will never
leave the cycle.

Hello guys,
I've looked at FreeBSD 8.0 cryptographically secure pseudorandom
numbers generator and have a question. It looks like a bug but I'am
not sure.
In file sys/dev/randomdev.c, function random_read:
if (!random_systat.seeded)
error = (*random_systat.block)(flag);
3 matches
