| |
2.6.25-stable review patch. If anyone has any objections, please let us know.
------------------ From: Herbert Xu <herbert@gondor.apana.org.au> [CRYPTO] eseqiv: Fix off-by-one encryption
[ Upstream commit: 46f8153cc59384eb09a426d044668d4801f818ce ]
After attaching the IV to the head during encryption, eseqiv does not increase the encryption length by that amount. As such the last block of the actual plain text will be left unencrypted.
Fortunately the only user of this code hifn currently crashes so this shouldn't affect anyone :)
