crypto: hisilicon - Use the offset fields in sqe to avoid need to split scatterlists

2020-02-11T12:35:30+00:00

commit 484a897ffa3005f16cd9a31efd747bcf8155826f upstream. We can configure sgl offset fields in ZIP sqe to let ZIP engine read/write sgl data with skipped data. Hence no need to splite the sgl.

crypto: hisilicon - avoid unused function warning

2019-09-20T13:05:33+00:00

The only caller of hisi_zip_vf_q_assign() is hidden in an #ifdef, so the function causes a warning when CONFIG_PCI_IOV is disabled: drivers/crypto/hisilicon/zip/zip_main.c:740:12: error: unused function 'hisi_zip_vf_q_assign' [-Werror,-Wunused-function] Replace the #ifdef with an IS_ENABLED() check that leads to the function being dropped based on the configuration.

crypto: hisilicon - Fix return value check in hisi_zip_acompress()

2019-09-20T12:53:09+00:00

The return valude of add_comp_head() is int, but @head_size is size_t, which is a unsigned type. size_t head_size; ... if (head_size < 0) // it will never work return -ENOMEM Modify the type of @head_size to int, then change the type to size_t when invoke hisi_zip_create_req() as a parameter.

crypto: hisilicon - Matching the dma address for dma_pool_free()

2019-09-20T12:53:09+00:00

When dma_pool_zalloc() fail in sec_alloc_and_fill_hw_sgl(), dma_pool_free() is invoked, but the parameters that sgl_current and sgl_current->next_sgl is not match. Using sec_free_hw_sgl() instead of the original free routine. Fixes: 915e4e8413da ("crypto: hisilicon - SEC security accelerator driver") Signed-off-by: Yunfeng Ye Signed-off-by: Herbert Xu

crypto: hisilicon - Fix double free in sec_free_hw_sgl()

2019-09-20T12:53:09+00:00

There are two problems in sec_free_hw_sgl(): First, when sgl_current->next is valid, @hw_sgl will be freed in the first loop, but it free again after the loop. Second, sgl_current and sgl_current->next_sgl is not match when dma_pool_free() is invoked, the third parameter should be the dma address of sgl_current, but sgl_current->next_sgl is the dma address of next chain, so use sgl_current->next_sgl is wrong. Fix this by deleting the last dma_pool_free() in sec_free_hw_sgl(), modifying the condition for while loop, and matching the address for dma_pool_free().

crypto: hisilicon - select CRYPTO_LIB_DES while compiling SEC driver
