CVS commit: src/sys/opencrypto

["Matthias Drochner" <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Tue May 24 18:52:52 UTC 2011

Modified Files:
        src/sys/opencrypto: cryptosoft.c cryptosoft_xform.c

Log Message:
Change the way the IV is generated for AES-CTR: use a simple counter
instead of arc4random(). AES-CTR is sensitive against IV recurrence
(with the same key / nonce), and a random number doesn't give that
guarantee.
This needs a little API change in cryptosoft -- I've suggested it to
Open/FreeBSD, might change it depending on feedback.
Thanks to Steven Bellovin for hints.
