From: Marek Vasut Subject: [PATCH 1/3] crypto: Fully restore ahash request before completing Date: Thu, 26 Sep 2013 13:18:24 +0200 Message-ID: <1380194306-5243-1-git-send-email-marex@denx.de> Cc: linux-arm-kernel@lists.infradead.org, Marek Vasut , Herbert Xu , "David S. Miller" To: linux-crypto@vger.kernel.org Return-path: Received: from mail-out.m-online.net ([212.18.0.10]:51279 "EHLO mail-out.m-online.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755712Ab3IZLSl (ORCPT ); Thu, 26 Sep 2013 07:18:41 -0400 Sender: linux-crypto-owner@vger.kernel.org List-ID: When finishing the ahash request, the ahash_op_unaligned_done() will call complete() on the request. Yet, this will not call the correct complete callback. The correct complete callback was previously stored in the requests' private data, as seen in ahash_op_unaligned(). This patch restores the correct complete callback and .data field of the request before calling complete() on it. Signed-off-by: Marek Vasut Cc: Herbert Xu Cc: David S.
