* | crypto: stm32 - Try to fix hash paddingArnd Bergmann2017-10-071-6/+9
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc warns that the length for the extra unaligned data in the hash function may be used unaligned. In theory this could happen if we pass a zero-length sg_list, or if sg_is_last() was never true: In file included from drivers/crypto/stm32/stm32-hash.c:23: drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_one_request': include/uapi/linux/kernel.h:12:49: error: 'ncp' may be used uninitialized in this function [-Werror=maybe-uninitialized] #define __KERNEL_DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d)) Neither of these can happen in practice, so the warning is harmless. However while trying to suppress the warning, I noticed multiple problems with that code: - On big-endian kernels, we byte-swap the data like we do for register accesses, however this is a data stream and almost certainly needs to use a single writesl() instead of series of writel() to give the correct hash. - If the length is not a multiple of four bytes, we skip the last word entirely, since we write the truncated length using stm32_hash_set_nblw(). - If we change the code to round the length up rather than down, the last bytes contain stale data, so it needs some form of padding. This tries to address all four problems, by correctly initializing the length to zero, using endian-safe copy functions, adding zero-padding and passing the padded length. I have done no testing on this patch, so please review carefully and if possible test with an unaligned length and big-endian kernel builds.

* crypto: stm32 - Support for STM32 CRC32 crypto moduleFabien DESSENNE2017-04-053-0/+333
This module registers a CRC32 ("Ethernet") and a CRC32C (Castagnoli) algorithm that make use of the STMicroelectronics STM32 crypto hardware. Theses algorithms are compatible with the little-endian generic ones. Both algorithms use ~0 as default seed (key). With CRC32C the output is xored with ~0. Using TCRYPT CRC32C speed test, this shows up to 900% speedup compared to the crc32c-generic algorithm.
