2022-09-24crypto: inside-secure - Replace generic aes with libaesPeter Harliman Liem
Commit 363a90c2d517 ("crypto: safexcel/aes - switch to library version of key expansion routine") removed CRYPTO_AES in the config. However, some portions of codes still rely on generic AES cipher (e.g. refer to safexcel_aead_gcm_cra_init(), safexcel_xcbcmac_cra_init()). This causes transform allocation failure for those algos, if CRYPTO_AES is not manually enabled. To resolve that, we replace all existing AES cipher dependent codes with their AES library counterpart.

2022-09-24crypto: inside_secure - Avoid dma map if size is zeroPeter Harliman Liem
From commit d03c54419274 ("dma-mapping: disallow .map_sg operations from returning zero on error"), dma_map_sg() produces warning if size is 0. This results in visible warnings if crypto length is zero. To avoid that, we avoid calling dma_map_sg if size is zero.

2022-09-16crypto: qat - use reference to structure in dma_map_single()Damian Muszynski
When mapping the input and output parameters, the implementations of RSA and DH pass to the function dma_map_single() a pointer to the first member of the structure they want to map instead of a pointer to the actual structure. This results in set of warnings reported by the static analyser Smatch: drivers/crypto/qat/qat_common/qat_asym_algs.c:335 qat_dh_compute_value() error: dma_map_single_attrs() '&qat_req->in.dh.in.b' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:341 qat_dh_compute_value() error: dma_map_single_attrs() '&qat_req->out.dh.r' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:732 qat_rsa_enc() error: dma_map_single_attrs() '&qat_req->in.rsa.enc.m' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:738 qat_rsa_enc() error: dma_map_single_attrs() '&qat_req->out.rsa.enc.c' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:878 qat_rsa_dec() error: dma_map_single_attrs() '&qat_req->in.rsa.dec.c' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:884 qat_rsa_dec() error: dma_map_single_attrs() '&qat_req->out.rsa.dec.m' too small (8 vs 64) Where the address of the first element of a structure is used as an input for the function dma_map_single(), replace it with the address of the structure.

2022-09-16Revert "crypto: qat - reduce size of mapped region"Giovanni Cabiddu
This reverts commit e48767c17718067ba21fb2ef461779ec2506f845. In an attempt to resolve a set of warnings reported by the static analyzer Smatch, the reverted commit improperly reduced the sizes of the DMA mappings used for the input and output parameters for both RSA and DH creating a mismatch (map size=8 bytes, unmap size=64 bytes). This issue is reported when CONFIG_DMA_API_DEBUG is selected, when the crypto self test is run. The function dma_unmap_single() reports a warning similar to the one below, saying that the `device driver frees DMA memory with different size`. DMA-API: 4xxx 0000:06:00.0: device driver frees DMA memory with different size [device address=0x0000000123206c80] [map size=8 bytes] [unmap size=64 bytes] WARNING: CPU: 0 PID: 0 at kernel/dma/debug.c:973 check_unmap+0x3d0/0x8c0\ ...

2022-09-16crypto: qat - fix DMA transfer directionDamian Muszynski
When CONFIG_DMA_API_DEBUG is selected, while running the crypto self test on the QAT crypto algorithms, the function add_dma_entry() reports a warning similar to the one below, saying that overlapping mappings are not supported. This occurs in tests where the input and the output scatter list point to the same buffers (i.e. two different scatter lists which point to the same chunks of memory). The logic that implements the mapping uses the flag DMA_BIDIRECTIONAL for both the input and the output scatter lists which leads to overlapped write mappings. These are not supported by the DMA layer. Fix by specifying the correct DMA transfer directions when mapping buffers. For in-place operations where the input scatter list matches the output scatter list, buffers are mapped once with DMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flag DMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE. Overlapping a read mapping with a write mapping is a valid case in dma-coherent devices like QAT. The function that frees and unmaps the buffers, qat_alg_free_bufl() has been changed accordingly to the changes to the mapping function. DMA-API: 4xxx 0000:06:00.0: cacheline tracking EEXIST, overlapping mappings aren't supported WARNING: CPU: 53 PID: 4362 at kernel/dma/debug.c:570 add_dma_entry+0x1e9/0x270 ...

Hash and Crypto Engine (HACE) is designed to accelerate the throughput of hash data digest, encryption, and decryption. Basically, HACE can be divided into two independently engines - Hash Engine and Crypto Engine. This patch aims to add HACE hash engine driver for hash accelerator.

2022-08-26crypto: ccp - Fail the PSP initialization when writing psp data file failedJacky Li
Currently the OS continues the PSP initialization when there is a write failure to the init_ex_file. Therefore, the userspace would be told that SEV is properly INIT'd even though the psp data file is not updated. This is problematic because later when asked for the SEV data, the OS won't be able to provide it.

2022-08-26crypto: ccp - Initialize PSP when reading psp data file failedJacky Li
Currently the OS fails the PSP initialization when the file specified at 'init_ex_path' does not exist or has invalid content. However the SEV spec just requires users to allocate 32KB of 0xFF in the file, which can be taken care of by the OS easily. To improve the robustness during the PSP init, leverage the retry mechanism and continue the init process: Before the first INIT_EX call, if the content is invalid or missing, continue the process by feeding those contents into PSP instead of aborting. PSP will then override it with 32KB 0xFF and return SEV_RET_SECURE_DATA_INVALID status code. In the second INIT_EX call, this 32KB 0xFF content will then be fed and PSP will write the valid data to the file. In order to do this, sev_read_init_ex_file should only be called once for the first INIT_EX call. Calling it again for the second INIT_EX call will cause the invalid file content overwriting the valid 32KB 0xFF data provided by PSP in the first INIT_EX call.
