Convert the driver to use autosuspend for runtime_pm. This boosts the performance, and optimizes the power consumption for the driver. By default, the timeout value for autosuspend is set to one second. Signed-off-by:

AES can have multiple HW accelerator cores in the system, in which case each core has its own crypto engine in use. Currently, the used hardware device is stored under the omap_aes_ctx struct, which is global for the algorithm itself, causing conflicts when used with multiple cores. Fix this by moving the used HW device under reqctx, which is stored per-request basis. Signed-off-by:

When a hw_random device's quality is non-zero, it will automatically be used to fill the kernel's entropy pool. Since timeriomem_rng is used by many different devices, the quality needs to be provided by platform data or device tree. Signed-off-by:

Many HMAC users directly use directly 0x36/0x5c values. It's better with crypto to use a name instead of directly some crypto constant. This patch simply add HMAC_IPAD_VALUE/HMAC_OPAD_VALUE defines in a new include file "crypto/hmac.h" and use them in crypto/hmac.c Signed-off-by:

When using the "aes-asm" implementation of AES (*not* the AES-NI implementation) on an x86_64, v4.12-rc1 kernel with lockdep enabled, the following warning was reported, along with a long unwinder dump: WARNING: kernel stack regs at ffffc90000643558 in kworker/u4:2:155 has bad 'bp' value 000000000000001c The problem is that aes_enc_block() and aes_dec_block() use %rbp as a temporary register, which breaks stack traces if an interrupt occurs. Fix this by replacing %rbp with %r9, which was being used to hold the saved value of %rbp. This required rearranging the AES round macro slightly since %r9d cannot be used as the target of a move from %ah-%dh. Performance is essentially unchanged --- actually about 0.2% faster than before. Interestingly, I also measured aes-generic as being nearly 7% faster than aes-asm, so perhaps aes-asm has outlived its usefulness... Signed-off-by:

CAAM RSA private key may have either of three representations. 1. The first representation consists of the pair (n, d), where the components have the following meanings: n the RSA modulus d the RSA private exponent 2. The second representation consists of the triplet (p, q, d), where the components have the following meanings: p the first prime factor of the RSA modulus n q the second prime factor of the RSA modulus n d the RSA private exponent 3. The third representation consists of the quintuple (p, q, dP, dQ, qInv), where the components have the following meanings: p the first prime factor of the RSA modulus n q the second prime factor of the RSA modulus n dP the first factors's CRT exponent dQ the second factors's CRT exponent qInv the (first) CRT coefficient The benefit of using the third or the second key form is lower computational cost for the decryption and signature operations. This patch adds support for the third RSA private key representations and extends caampkc to use the fastest key when all related components are present in the private key.

The tcrypt AEAD cycles speed tests disables irqs during the test, which is broken at the very least since commit '1425d2d1 ("crypto: tcrypt - Fix AEAD speed tests")' adds a wait for completion as part of the test and probably since switching to the new AEAD API. While the result of taking a cycle count diff may not mean much on SMP systems if the task migrates, it's good enough for tcrypt being the quick & dirty dev tool it is. It's also what all the other (i.e. hash) cycle speed tests do. Signed-off-by:
