Re: Linux 3.6-rc5
From: Jussi Kivilinna

Quoting Romain Francoise <romain@xxxxxxxxxxxxx>:
Still seeing this BUG with -rc5, that I originally reported here:
http://marc.info/?l=linux-crypto-vger&m=134653220530264&w=2
Does reverting e46e9a46386bca8e80a6467b5c643dc494861896 help?
That commit added crypto selftest for authenc(hmac(sha1),cbc(aes)) in
3.6, and probably made this bug visible (but not directly causing it).
