We propose a new crypto type called crypto_acomp_type, a new struct acomp_alg and struct crypto_acomp, together with number of helper functions to register acomp type algorithms and allocate tfm instances. This interface will allow the following operations: int (*compress)(struct acomp_req *req); int (*decompress)(struct acomp_req *req); Together with acomp we propose a new driver-side interface, scomp, which handles compression implementations which use linear buffers. We converted all compression algorithms available in LKCF to use this interface so that those algorithms will be accessible through the acomp api. Finally we propose qdecomp, a simple decompression api for algorithms which do not need work space for performing decompression operations. Changes in v4: - added qdecompress api, a front-end for decompression algorithms which do not need additional vmalloc work space Changes in v3: - added driver-side scomp interface - provided support for lzo, lz4, lz4hc, 842, deflate compression algorithms via the acomp api (through scomp) - extended testmgr to support acomp - removed extended acomp api for supporting deflate algorithm parameters (will be enhanced and re-proposed in future) Note that (2) to (7) are a rework of Joonsoo Kim's scomp patches. Changes in v2: - added compression and decompression request sizes in acomp_alg in order to enable noctx support - extended api with helpers to allocate compression and decompression requests Changes from initial submit: - added consumed and produced fields to acomp_req - extended api to support configuration of deflate compressors --- Giovanni Cabiddu (10): crypto: shrink hash down to two types crypto: add asynchronous compression api crypto: add driver-side scomp interface crypto: add quick decompression api crypto: acomp - add support for lzo via scomp crypto: acomp - add support for lz4 via scomp crypto: acomp - add support for lz4hc via scomp crypto: acomp - add support for 842 via scomp crypto: acomp - add support for deflate via scomp crypto: acomp - update testmgr with support for acomp crypto/842.c | 82 ++++++++- crypto/Kconfig | 15 ++ crypto/Makefile | 4 + crypto/acompress.c | 209 ++++++++++++++++++++ crypto/crypto_user.c | 21 ++ crypto/deflate.c | 111 ++++++++++- crypto/lz4.c | 91 ++++++++- crypto/lz4hc.c | 92 ++++++++- crypto/lzo.c | 97 ++++++++-- crypto/qdecompress.c | 93 +++++++++ crypto/scompress.c | 345 +++++++++++++++++++++++++++++++++ crypto/testmgr.c | 158 ++++++++++++++-- include/crypto/acompress.h | 251 ++++++++++++++++++++++++ include/crypto/internal/acompress.h | 97 +++++++++ include/crypto/internal/qdecompress.h | 22 ++ include/crypto/internal/scompress.h | 148 ++++++++++++++ include/crypto/qdecompress.h | 204 +++++++++++++++++++ include/linux/crypto.h | 17 ++- 18 files changed, 1991 insertions(+), 66 deletions(-) create mode 100644 crypto/acompress.c create mode 100644 crypto/qdecompress.c create mode 100644 crypto/scompress.c create mode 100644 include/crypto/acompress.h create mode 100644 include/crypto/internal/acompress.h create mode 100644 include/crypto/internal/qdecompress.h create mode 100644 include/crypto/internal/scompress.h create mode 100644 include/crypto/qdecompress.h -- 1.7.4.1
