All LZ77 algorithms need to clear the literal length in the context to avoid coupling of literal data between data segments in the stream mode. Signed-off-by: Chenghai Huang <huangchenghai2@huawei.com>
When tail data is being compress, if the buffer data is not cleared, a nospace or again status needs to be returned to notify the user to add output space. Signed-off-by: Chenghai Huang <huangchenghai2@huawei.com>
The tail packet padding function depends on the driver. Therefore, this function is moved to the driver layer for implementation, so as to remove unnecessary processes at the algorithm layer. Signed-off-by: Chenghai Huang <huangchenghai2@huawei.com>
When the output space is too large, the function is not affected. Therefore, the printf of displaying a large number of messages is deleted. Signed-off-by: Chenghai Huang <huangchenghai2@huawei.com>
… device failure 1. Add max timeout control and adaptive backoff to prevent long usleep delays on device failure 2. Implement exponential backoff to reduce context switching overhead under high load. Signed-off-by: lizhi <lizhi206@huawei.com>
The key align size of hashjoin is changed now, make it match the hardware. Signed-off-by: Wenkai Lin <linwenkai6@hisilicon.com>
Some clean code to improve the readability of the wd_agg code. Signed-off-by: Wenkai Lin <linwenkai6@hisilicon.com>
Fix parameter validation during the coding process. Adopt constant-time programming techniques for handling sensitive data to enhance code resilience against attacks. Signed-off-by: Longfang Liu <liulongfang@huawei.com>
Add WD_DEFLATE branch in append_store_block() to output a 5-byte store block when stream compression receives an empty last packet Signed-off-by: ZongYu Wu <wuzongyu1@huawei.com>
In the HPRE module's big number comparison, the previous implementation used memcmp to compare big numbers of the same length. On little-endian platforms, this approach compares data starting from the Least Significant Bit (LSB), which can lead to incorrect results—such as a larger value in the lower bits being misinterpreted as greater overall, even if the higher bits are smaller. To address this, the comparison logic must be modified to consistently start from the Most Significant Bit (MSB). Signed-off-by: Longfang Liu <liulongfang@huawei.com>
The HPRE driver must store and process data in big-endian (MSB) format as specified by the chip design. Therefore, the comparison logic for this data should also be described and implemented following the big-endian convention. Signed-off-by: Longfang Liu <liulongfang@huawei.com>
