New subject: [PATCH 01/24] uadk_prov: fix some cleancode issues and bugs for rsa

From: Qi Tao taoqi10@huawei.com

The major issues that have been resolved are as follows: 1. In uadk_prov_rsa_init(), a deadlock occurs when a lock is returned before it is released. 2. In rsa_check_bit_useful(), the unit of the bits parameter is bit, and the unit of the flen parameter is byte. They cannot be compared directly. 3. As "new" and "export" are keywords in C++, there will be compile error with mocker UT framework. 4. In the case of an exception, the return value of the RSA_padding_xxx function is not 0. 5. Switch to software calculation only when one of the following three conditions occur, indicating that the hardware initialization fails, hardware services fail to be executed and the packet length specification is not supported.

New subject: [PATCH 03/24] uadk_provider: add openssl ffc library function

As DH needs FFC(Finite Field Cryptography) API of OpenSSL, but the OpenSSL3.x does not place these APIs in external header file currently. Therefore, we put the related APIs in independent file of uadk_provider.

New subject: [PATCH 08/24] uadk_provider: code cleanup for uadk_provider and uadk_engine

From: Chenghai Huang huangchenghai2@huawei.com

Deleted unnecessary return values and modified the format.

Use a unified format to define the return values of success and failure.

New subject: [PATCH 10/24] uadk_engine: optimized engine update process

From: Chenghai Huang huangchenghai2@huawei.com

In the update operation, the first packet needs to combine the previous unprocessed data into a 512 KB packet for calculation.

Other data is calculated based on the maximum packet length (16M-512B) of the UADK

In this way, a computing resource required for copying may be omitted, and a data volume of once hardware computation may be increased, thereby reducing a quantity of times of sending and receiving data, and better exerting hardware acceleration performance.

New subject: [PATCH 11/24] uadk_provider: fix cipher issue when input len is 0 in decrypto update

From: Chenghai Huang huangchenghai2@huawei.com

In the decrypted filled data update process, the input size will be zero when the input size is smaller than the block size. As a result, an error message indicating that the output size is 0 is reported by UDAK.

Therefore, it need to check whether the input length is 0 before UADK encryption/decryption.

In addition, if the input length is greater than 0 and smaller than the block size, that is, the length of the data currently to be processed is 0, the data needs to be cached in the buffer through ossl_cipher_trailingdata() and sent to the next step.

New subject: [PATCH 13/24] uadk_provider: fix the key and IV verification methods for cipher init

From: Chenghai Huang huangchenghai2@huawei.com

The OpenSSL enc tool call EVP_CipherInit_ex() twice. The first time is to initialize the encryption/decryption algorithm, and the second time is to input the key and IV parameters. Therefore, an empty key and iv will be passed in the first call.

A flag bit needs to be added to indicate whether the key and IV have been set. Otherwise, the key and IV that are not set will cause a cipher error.

New subject: [PATCH 16/24] uadk_provider: modify poll loop exit condition

From: Chenghai Huang huangchenghai2@huawei.com

When the num of recv packets is greater than the expected number. The condition that expected nums equal to actual nums, for exiting the poll loop will cause a long retry loop.

Therefore, the loop exit condition is modified, and full_sem is reduced when no task needs to be queried.

New subject: [PATCH 18/24] uadk_engine: fixup pubkey size used in reverse operation

The length of the pubkey get from wd_ecxdh_get_out_params() may not be 'key_size', the actual value in 'dsize' may smaller than 'key_size'. So copy 'key_size' length to ecx_key->pubkey will make the reverse_bytes() operates on incorrect pubkey length, which will make the actual value changed. Fix this issue by using the length filled in 'dsize'.

New subject: [PATCH 19/24] uadk_provider: add aes cts alg to uadk_provider in openssl3.0

From: Chenghai Huang huangchenghai2@huawei.com

Add AES-128-CBC-CTS AES-192-CBC-CTS AES-256-CBC-CTS to uadk_provider. Each alg has 3 modes, such as CS1, CS2, and CS3.

The default mode is CS1. You can select a mode by setting the OSSL_CIPHER_PARAM_CTS_MODE parameter.

New subject: [PATCH 20/24] uadk_provider: bugfix cipher decryption issue

From: Chenghai Huang huangchenghai2@huawei.com

On openssl version 3.0, the pad function is not enabled in the default scenario. After the data encrypted by pad is decrypted, the result is inconsistent with the original data.

Therefore, pad processing needs to be performed through soft calculation to ensure that the results are correct.

New subject: [PATCH 22/24] uadk_provider/rsa: unify function definitions with macro

Use UADK_PKEY_KEYMGMT_DESCR, UADK_PKEY_SIGNATURE_DESCR and UADK_PKEY_ASYM_CIPHER_DESCR macro to unify the definitions of RSA functions, reducing code duplication ratio.

New subject: [PATCH 24/24] uadk_prov: fix data type conversion errors

From: Qi Tao taoqi10@huawei.com

Can not convert ‘size_t*’ {‘long unsigned int*’} to ‘int*’, which may cause data loss or other problems.
