Subject: Possible bug: blkcipher_walk_done()
Date: Wed, 10 Feb 2010 11:42:13 +0200	[thread overview]
Message-ID: <4B727F75.20305@nokia.com> (raw)

Hi,

It seems that there is a mistake in the implementation of

int blkcipher_walk_done(struct blkcipher_desc *desc,
            struct blkcipher_walk *walk, int err)

blkcipher_walk_virt() will call crypto_kmap() to map page.

But in the case then err argument is < 0 and we cannot continue then
blkcipher_walk_done() will not
unmap the page.

What do you think?

- Dmitry
