2020-05-23crypto: stm32/crc32 - protect from concurrent accessesNicolas Toromanoff
Protect STM32 CRC device from concurrent accesses. As we create a spinlocked section that increase with buffer size, we provide a module parameter to release the pressure by splitting critical section in chunks. Size of each chunk is defined in burst_size module parameter. By default burst_size=0, i.e. don't split incoming buffer.

2020-05-23crypto: stm32/crc32 - don't sleep in runtime pmNicolas Toromanoff
Ensure stm32_crc_update() and stm32_crc_init() can be called in atomic context and can't sleep. Add pm_runtime_irq_safe() to make pm_runtime_get_sync() atomic. Change runtime pm to call clk_enable()/clk_disable() and change system pm to unprepare/prepare the clock and force runtime pm suspend/resume.

2020-05-08crypto: lib/sha1 - fold linux/cryptohash.h into crypto/sha.hEric Biggers
<linux/cryptohash.h> sounds very generic and important, like it's the header to include if you're doing cryptographic hashing in the kernel. But actually it only includes the library implementation of the SHA-1 compression function (not even the full SHA-1). This should basically never be used anymore; SHA-1 is no longer considered secure, and there are much better ways to do cryptographic hashing in the kernel. Remove this header and fold it into <crypto/sha.h> which already contains constants and functions for SHA-1 (along with SHA-2).

<linux/cryptohash.h> sounds very generic and important, like it's the header to include if you're doing cryptographic hashing in the kernel. But actually it only includes the library implementation of the SHA-1 compression function (not even the full SHA-1). This should basically never be used anymore; SHA-1 is no longer considered secure, and there are much better ways to do cryptographic hashing in the kernel.

2020-05-08crypto: lib/sha1 - rename "sha" to "sha1"Eric Biggers
The library implementation of the SHA-1 compression function is confusingly called just "sha_transform()". Alongside it are some "SHA_" constants and "sha_init()". Presumably these are left over from a time when SHA just meant SHA-1. But now there are also SHA-2 and SHA-3, and moreover SHA-1 is now considered insecure and thus shouldn't be used. Therefore, rename these functions and constants to make it very clear that they are for SHA-1. Also add a comment to make it clear that these shouldn't be used. For the extra-misleadingly named "SHA_MESSAGE_BYTES", rename it to SHA1_BLOCK_SIZE and define it to just '64' rather than '(512/8)' so that it matches the same definition in <crypto/sha.h>. This prepares for merging <linux/cryptohash.h> into <crypto/sha.h>. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
