From: Geert Uytterhoeven Subject: [PATCH/RFC 0/8] Partial decompression API Date: Wed, 17 Dec 2008 17:36:35 +0100 Message-ID: <20081217163634.998961917@vixen.sonytel.be> Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=ISO-8859-1 Content-Transfer-Encoding: QUOTED-PRINTABLE Cc: linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org To: Herbert Xu Return-path: Received: from vervifontaine.sonytel.be ([80.88.33.193]:65181 "EHLO vervifontaine.sonycom.com" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1751411AbYLQQmA (ORCPT ); Wed, 17 Dec 2008 11:42:00 -0500 Sender: linux-crypto-owner@vger.kernel.org List-ID: The following patch series adds support for partial (de)compression to = the CRYPTO API, and modifies SquashFS 4 to use this: [1] crypto: testmgr - Correct comment about deflate parameters [2] crypto: compress - Add pcomp interface [3] crypto: testmgr - Add support for the pcomp interface [4] crypto: api - Add type init function to crypto_tfm [5] crypto: api - Export pcomp through comp [6] crypto: deflate - switch to pcomp [7] crypto: testmgr - swith deflate test to pcomp [8] squashfs: Make SquashFS 4 use the new pcomp crypto interface All patches are relative to cryptodev-2.6.git, except for the last one,= which is relative to squashfs-2.6.git. The first patch is independent and can be applied immediately, but I in= cluded it in this series to avoid rejects. The backwards-compatibility layer has been tested with IPComp and UBIFS= =2E Changes since last version (2008-11-24): - Add a new "pcomp" crypto interface, instead of modifying the existi= ng "comp" interface, with a compatibility layer, - Modify the existing "deflate" module, instead of adding a new "zlib= " module, - Add support for the configuration of (de)compression parameters, - Separate allocation for compression and decompression, to avoid mem= ory wastage.
