2018-07-09crypto: ahash - remove useless setting of type flagsEric Biggers1-16/+8
Many ahash algorithms set .cra_flags = CRYPTO_ALG_TYPE_AHASH. But this is redundant with the C structure type ('struct ahash_alg'), and crypto_register_ahash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the ahash algorithms. This patch shouldn't change any actual behavior.

2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook1-2/+3
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-01-12crypto: hash - annotate algorithms taking optional keyEric Biggers1-0/+2
We need to consistently enforce that keyed hashes cannot be used without setting the key. To do this we need a reliable way to determine whether a given hash algorithm is keyed or not. AF_ALG currently does this by checking for the presence of a ->setkey() method. However, this is actually slightly broken because the CRC-32 algorithms implement ->setkey() but can also be used without a key. (The CRC-32 "key" is not actually a cryptographic key but rather represents the initial state. If not overridden, then a default initial state is used.) Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which indicates that the algorithm has a ->setkey() method, but it is not required to be called. Then set it on all the CRC-32 algorithms. The same also applies to the Adler-32 implementation in Lustre. Also, the cryptd and mcryptd templates have to pass through the flag from their underlying algorithm.

2017-10-07crypto: stm32 - Try to fix hash paddingArnd Bergmann1-6/+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.

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.
