2023-02-03crypto: stm32/hash - Support Ux500 hashLinus Walleij1-35/+219
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.

2023-02-03crypto: stm32/hash - Wait for idle before final CPU xmitLinus Walleij1-0/+3
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.

2023-02-03crypto: stm32/hash - Use existing busy poll functionLinus Walleij1-2/+4
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.

We are passing (rctx->flags & HASH_FLAGS_FINUP) as indicator for the final request but we already know this to be true since we are in the (final) arm of an if-statement set from the same flag.

2023-02-03dt-bindings: crypto: Let STM32 define Ux500 HASHLinus Walleij1-1/+22
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.

2023-02-03crypto: qat - add qat_zlib_deflateLucas Segarra Fernandez1-12/+154
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.

2023-01-13crypto: sun8i-ce - Add TRNG clock to the D1 variantSamuel Holland2-1/+2
At least the D1 variant requires a separate clock for the TRNG. Without this clock enabled, reading from /dev/hwrng reports: sun8i-ce 3040000.crypto: DMA timeout for TRNG (tm=96) on flow 3 Experimentation shows that the necessary clock is the SoC's internal RC oscillator. This makes sense, as noise from the oscillator can be used as a source of entropy.

2023-01-13dt-bindings: crypto: sun8i-ce: Add compatible for D1Samuel Holland1-8/+25
D1 has a crypto engine similar to the one in other Allwinner SoCs. Like H6, it has a separate MBUS clock gate. It also requires the internal RC oscillator to be enabled for the TRNG to return data, presumably because noise from the oscillator is used as an entropy source. This is likely the case for earlier variants as well, but it really only matters for H616 and newer SoCs, as H6 provides no way to disable the internal oscillator.

2023-01-13crypto: skcipher - Use scatterwalk (un)map interface for dst and src buffersArd Biesheuvel1-18/+4
The skcipher walk API implementation avoids scatterwalk_map() for mapping the source and destination buffers, and invokes kmap_atomic() directly if the buffer in question is not in low memory (which can only happen on 32-bit architectures). This avoids some overhead on 64-bit architectures, and most notably, permits the skcipher code to run with preemption enabled. Now that scatterwalk_map() has been updated to use kmap_local(), none of this is needed, so we can simply use scatterwalk_map/unmap instead.
