Commit c388f458 ("hwrng: starfive - Add TRNG driver for StarFive SoC") adds the STARFIVE TRNG DRIVER section to MAINTAINERS, but refers to the non-existing file drivers/char/hw_random/starfive-trng.c rather than to the actually added file drivers/char/hw_random/jh7110-trng.c in this commit. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair this file entry in STARFIVE TRNG DRIVER.

It turns out we can just modify the newer STM32 HASH driver to be used with Ux500 and now that we have done that, delete the old and sparsely maintained Ux500 HASH driver. Signed-off-by:

The Ux500 has a hash block which is an ancestor to the STM32 hash block. With some minor code path additions we can support also this variant in the STM32 driver. Differences: - Ux500 only supports SHA1 and SHA256 (+/- MAC) so we split up the algorithm registration per-algorithm and register each algorithm along with its MAC variant separately. - Ux500 does not have an interrupt to indicate that hash calculation is complete, so we add code paths to handle polling for completion if the interrupt is missing in the device tree. - Ux500 is lacking the SR status register, to check if an operating is complete, we need to poll the HASH_STR_DCAL bit in the HASH_STR register instead. - Ux500 had the resulting hash at address offset 0x0c and 8 32bit registers ahead. We account for this with a special code path when reading out the hash digest. - Ux500 need a special bit set in the control register before performing the final hash calculation on an empty message. - Ux500 hashes on empty messages will be performed if the above bit is set, but are incorrect. For this reason we just make an inline synchronous hash using a fallback hash. Tested on the Ux500 Golden device with the extended tests. Acked-by:

When calculating the hash using the CPU, right before the final hash calculation, heavy testing on Ux500 reveals that it is wise to wait for the hardware to go idle before calculating the final hash. The default test vectors mostly worked fine, but when I used the extensive tests and stress the hardware I ran into this problem. Acked-by:

When exporting state we are waiting indefinitely in the same was as the ordinary stm32_hash_wait_busy() poll-for-completion function but without a timeout, which means we could hang in an eternal loop. Fix this by waiting for completion like the rest of the code. Acked-by:

This adds device tree bindings for the Ux500 HASH block as a compatible in the STM32 HASH bindings. The Ux500 HASH binding has been used for ages in the kernel device tree for Ux500 but was never documented, so fill in the gap by making it a sibling of the STM32 HASH block, which is what it is. The relationship to the existing STM32 HASH block is pretty obvious when looking at the register map, and I have written patches to reuse the STM32 HASH driver on the Ux500. The main difference from the outside is that the Ux500 HASH lacks the interrupt line, so some special if-clauses are needed to accomodate this in the binding. Reviewed-by:

The ZLIB format (RFC 1950) is made of deflate compressed data surrounded by a header and a footer. The QAT accelerators support only the deflate algorithm, therefore the header and the footer need to be inserted in software. This adds logic in the QAT driver to support the ZLIB format. In particular: * Generalize the function qat_comp_alg_compress_decompress() to allow skipping an initial region (header) of the source and/or destination scatter lists. * Add logic to register the qat_zlib_deflate algorithm into the acomp framework. * For ZLIB compression, skip the initial portion of the destination buffer before sending the job to the QAT accelerator and insert the ZLIB header and footer in the callback, after the QAT request has been processed. * For ZLIB decompression, parse the header in the input buffer provided by the user and verify its validity before attempting the decompression of the buffer with QAT. Then submit the buffer to QAT for decompression. In the callback verify the correctness of the footer by comparing the value of the ADLER produced by QAT with the one in the destination buffer.

Extend qat_bl_sgl_to_bufl() to allow skipping the mapping of a region of the source and the destination scatter lists starting from byte zero. This is to support the ZLIB format (RFC 1950) in the qat driver. The ZLIB format is made of deflate compressed data surrounded by a header and a footer. The QAT accelerators support only the deflate algorithm, therefore the header should not be mapped since it is inserted in software. Signed-off-by:

Revert "crypto: rsa-pkcs1pad - Replace GFP_ATOMIC with GFP_KERNEL in pkcs1pad_encrypt_sign_complete" This reverts commit 1ca28098. While the akcipher API as a whole is designed to be called only from thread context, its completion path is still called from softirq context as usual. Therefore we must not use GFP_KERNEL on that path. Signed-off-by:

The minimum version of binutils for kernel build is currently 2.23 and it doesn't support GFNI. So, it fails to build the aria-avx512 if the old binutils is used. aria-avx512 requires GFNI, so it should not be allowed to build if the old binutils is used. The AS_AVX512 and AS_GFNI are added to the Kconfig to disable build aria-avx512 if the old binutils is used. Fixes: c970d420 ("crypto: x86/aria - implement aria-avx512") Reported-by:

While reviewing dependencies in some Kconfig files, I noticed the redundant dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always, since its introduction, been dependent on the config PCI. So, it is sufficient to just depend on PCI_MSI, and know that the dependency on PCI is implicitly implied. Reduce the dependencies of configs CRYPTO_DEV_HISI_SEC2, CRYPTO_DEV_HISI_QM, CRYPTO_DEV_HISI_ZIP and CRYPTO_DEV_HISI_HPRE. No functional change and effective change of Kconfig dependendencies.

When reading or writing crypto buffers the inner loops can be replaced with readsl and writesl which will on ARM result in a tight assembly loop, speeding up encryption/decryption a little bit. This optimization was in the Ux500 driver so let's carry it over to the STM32 driver.
