The following patch set introduces acomp, a generic asynchronous (de)compression api. What is proposed is a new crypto type called crypto_acomp_type, plus 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 is to make it similar to how the existing crypto API works for the ablkcipher, ahash, and aead types. This interface will allow the following operations: int (*compress)(struct acomp_req *req); int (*decompress)(struct acomp_req *req); The main benefit that this API gives is to allow for asynchronous implementations that can use compression hardware to offload the computation. 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 with different context sizes Changes from initial submit: - added consumed and produced fields to acomp_req - extended api to support configuration of deflate compressors --- Giovanni Cabiddu (2): crypto: add asynchronous compression api crypto: extended acomp api for supporting deflate algorithm parameters crypto/Kconfig | 10 + crypto/Makefile | 2 + crypto/acompress.c | 134 +++++++++++ crypto/crypto_user.c | 21 ++ include/crypto/acompress.h | 438 +++++++++++++++++++++++++++++++++++ include/crypto/internal/acompress.h | 90 +++++++ include/linux/crypto.h | 1 + 7 files changed, 696 insertions(+), 0 deletions(-) create mode 100644 crypto/acompress.c create mode 100644 include/crypto/acompress.h create mode 100644 include/crypto/internal/acompress.h -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
