From d020055f5217be264e0bac9cd09ffc04233b9682 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 6 May 2008 14:01:24 +0800 Subject: CRYPTO: eseqiv: Fix off-by-one encryption [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 :) Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman --- crypto/eseqiv.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'crypto') diff --git a/crypto/eseqiv.c b/crypto/eseqiv.c index b14f14e314b6..881d30910434 100644 --- a/crypto/eseqiv.c +++ b/crypto/eseqiv.c @@ -136,7 +136,8 @@ static int eseqiv_givencrypt(struct skcipher_givcrypt_request *req) } ablkcipher_request_set_crypt(subreq, reqctx->src, dst, - req->creq.nbytes, req->creq.info); + req->creq.nbytes + ivsize, + req->creq.info); memcpy(req->creq.info, ctx->salt, ivsize); -- cgit v1.2.3
