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. Signed-off-by:

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. Signed-off-by:

Currently zip sqe is stored in hisi_zip_qp_ctx, which will bring corruption with multiple parallel users of the crypto tfm. This patch removes the zip_sqe in hisi_zip_qp_ctx and uses a temporary sqe instead. Signed-off-by:

Add callback reset_prepare and reset_done in QM, The callback reset_prepare will uninit device error configuration and stop the QM, the callback reset_done will init the device error configuration and restart the QM. Uninit the error configuration will disable device block master OOO when Multi-bit ECC error occurs to avoid the request of FLR will not return. Signed-off-by:

Add specific states for qm and qp, every state change under critical region to prevent from race condition. Meanwhile, qp state change will also depend on qm state. Due to the introduction of these states, it is necessary to pay attention to the calls of public logic, such as concurrent scenarios resetting and releasing queue will call hisi_qm_stop, which needs to add additional status to distinguish and process.

When building for ARMv7-M, clang-9 or higher tries to unroll some loops, which ends up confusing the register allocator to the point of generating rather bad code and using more than the warning limit for stack frames: warning: stack frame size of 1200 bytes in function 'blake2b_compress' [-Wframe-larger-than=] Forcing it to not unroll the final loop avoids this problem.

<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). Signed-off-by:

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:

Prefix the s390 SHA-1 functions with "s390_sha1_" rather than "sha1_". This allows us to rename the library function sha_init() to sha1_init() without causing a naming collision. Cc: linux-s390@vger.kernel.org Signed-off-by:

The PowerPC implementation of SHA-1 doesn't actually use the 16-word temporary array that's passed to the assembly code. This was probably meant to correspond to the 'W' array that lib/sha1.c uses. However, in sha1-powerpc-asm.S these values are actually stored in GPRs 16-31. Referencing SHA_WORKSPACE_WORDS from this code also isn't appropriate, since it's an implementation detail of lib/sha1.c. Therefore, just remove this unneeded array. Tested with: export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make mpc85xx_defconfig cat >> .config << EOF # CONFIG_MODULES is not set # CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set CONFIG_DEBUG_KERNEL=y CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y CONFIG_CRYPTO_SHA1_PPC=y EOF make olddefconfig make -j32 qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \ -kernel arch/powerpc/boot/zImage \ -append "cryptomgr.fuzz_iterations=1000 cryptomgr.panic_on_fail=1" Cc: linuxppc-dev@lists.ozlabs.org Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by:

In preparation for naming the SHA-1 stuff in <linux/cryptohash.h> properly and moving it to a more appropriate header, fix the HMAC-SHA256 code in mptcp_crypto_hmac_sha() to use SHA256_BLOCK_SIZE instead of "SHA_MESSAGE_BYTES" which is actually the SHA-1 block size. (Fortunately these are both 64 bytes, so this wasn't a "real" bug...) Cc: Paolo Abeni <pabeni@redhat.com> Cc: mptcp@lists.01.org Signed-off-by:
