Subject(Small) bias in generation of random passkeys for pairing
Hi!

There's a (small) bias in passkey generation in bluetooth:

get_random_bytes(&passkey, sizeof(passkey));
passkey %= 1000000;
put_unaligned_le32(passkey, smp->tk);

(there are at least two places doing this).

All passkeys are not of same probability, passkey "000000" is more
probable than "999999", but difference is small.

Do we care?
Pavel
