poor default seeding of RNG

[Tom Holroyd]

Correct me if I'm wrong, but init_rng() in entropy.c doesn't call
seed_rng(), and in fact seed_rng() isn't called from _anywhere_ (in
openssh-2.5.1p2).  So calls to BN_rand() only pick up the
tiny/non-existent amount of entropy added by BN_rand() itself from the
system clock (time in seconds).  Shouldn't seed_rng() be called from
init_rng()?  It should be called from _somewhere_, or deleted.

Thanks,
