crypto: vmx - fix incorrect kernel-doc comment syntax in files

2021-03-26T09:15:58Z

The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are certain files in drivers/crypto/vmx, which follow this syntax, but the content inside does not comply with kernel-doc. Such lines were probably not meant for kernel-doc parsing, but are parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. E.g., presence of kernel-doc like comment in the header line for drivers/crypto/vmx/vmx.c causes this warning by kernel-doc: "warning: expecting prototype for Routines supporting VMX instructions on the Power 8(). Prototype was for p8_init() instead" Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

crypto: vmx - convert to skcipher API

2019-05-30T07:28:40Z

Convert the VMX implementations of AES-CBC, AES-CTR, and AES-XTS from the deprecated "blkcipher" API to the "skcipher" API. As part of this, I moved the skcipher_request for the fallback algorithm off the stack and into the request context of the parent algorithm. I tested this in a PowerPC VM with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y. Signed-off-by: Eric Biggers Tested-by: Michael Ellerman Signed-off-by: Herbert Xu

crypto: powerpc - convert to use crypto_simd_usable()

2019-04-18T14:15:04Z

Replace all calls to in_interrupt() in the PowerPC crypto code with !crypto_simd_usable(). This causes the crypto self-tests to test the no-SIMD code paths when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y. The p8_ghash algorithm is currently failing and needs to be fixed, as it produces the wrong digest when no-SIMD updates are mixed with SIMD ones.

crypto: vmx - return correct error code on failed setkey

2019-04-18T14:14:58Z

In the VMX implementations of AES and AES modes, return -EINVAL when an invalid key length is provided, rather than some unusual error code determined via a series of additions. This makes the behavior match the other AES implementations in the kernel's crypto API. Cc: Daniel Axtens Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

2018-09-28T04:46:08Z

In the quest to remove all stack VLA usage from the kernel[1], this replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(), which uses a fixed stack size.

crypto: vmx - Remove overly verbose printk from AES init routines

2018-05-11T16:13:15Z

In the vmx AES init routines we do a printk(KERN_INFO ...) to report the fallback implementation we're using. However with a slow console this can significantly affect the speed of crypto operations. Using 'cryptsetup benchmark' the removal of the printk() leads to a ~5x speedup for aes-cbc decryption. So remove them.
