This patch adds the generic implementation of the MORUS family of AEAD algorithms (MORUS-640 and MORUS-1280). The original authors of MORUS are Hongjun Wu and Tao Huang. At the time of writing, MORUS is one of the finalists in CAESAR, an open competition intended to select a portfolio of alternatives to the problematic AES-GCM: https://competitions.cr.yp.to/caesar-submissions.html https://competitions.cr.yp.to/round3/morusv2.pdfSigned-off-by: NOndrej Mosnacek <omosnacek@gmail.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

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.

In the quest to remove all stack VLA usage from the kernel[1], this allocates the return code buffers before starting jiffie timers, rather than using stack space for the array. Additionally cleans up some exit paths and make sure that the num_mb module_param() is used only once per execution to avoid possible races in the value changing.

Enable CryptoCell support for hardware keys. Hardware keys are regular AES keys loaded into CryptoCell internal memory via firmware, often from secure boot ROM or hardware fuses at boot time. As such, they can be used for enc/dec purposes like any other key but cannot (read: extremely hard to) be extracted since since they are not available anywhere in RAM during runtime. The mechanism has some similarities to s390 secure keys although the keys are not wrapped or sealed, but simply loaded offline. The interface was therefore modeled based on the s390 secure keys support. Signed-off-by: NGilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

1020 bytes is the limit for associated data. Any more and it will no longer fit into hash_crypto_offset anymore. The hardware will not process aead requests with plaintext that have less than AES_BLOCK_SIZE bytes. When decrypting aead requests the authsize has to be taken in account as well, as it is part of the cryptlen. Otherwise the hardware will think it has been misconfigured and will return: aead return err status = 0x98 For rtc4543(gcm(aes)), the hardware has a dedicated GMAC mode as part of the hash function set.

To make this work, the driver will fallback if the counter is going to overlow. The aead's crypto4xx_setup_fallback() function is renamed to crypto4xx_aead_setup_fallback.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.
