2019-06-06crypto: inside-secure - improve the result error format when displayedAntoine Tenart
The result descriptors contain errors, which are represented as a bitmap. This patch updates the error message to not treat the error as a decimal value, but as an hexadecimal one. This helps in knowing the value does not have a direct meaning (the set bits themselves have).

2019-06-06crypto: inside-secure - remove useless checkAntoine Tenart
When sending an ahash request, the code checks for the extra variable not to be 0. This check is useless as the extra variable can't be 0 at this point (it is checked on the line just before). This patch does not modify the driver behaviour in any way. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2019-06-03locking/atomic, crypto/nx: Prepare for atomic64_read() conversionMark Rutland
The return type of atomic64_read() varies by architecture. It may return long (e.g. powerpc), long long (e.g. arm), or s64 (e.g. x86_64). This is somewhat painful, and mandates the use of explicit casts in some cases (e.g. when printing the return value). To ameliorate matters, subsequent patches will make the atomic64 API consistently use s64. As a preparatory step, this patch updates the nx-842 code to treat the return value of atomic64_read() as s64, using explicit casts. These casts will be removed once the s64 conversion is complete.

2019-05-30crypto: atmel-i2c - add support for SHA204A random number generatorArd Biesheuvel
The Linaro/96boards Secure96 mezzanine contains (among other things) an Atmel SHA204A symmetric crypto processor. This chip implements a number of different functionalities, but one that is highly useful for many different 96boards platforms is the random number generator. So let's implement a driver for the SHA204A, and for the time being, implement support for the random number generator only.

2019-05-30crypto: atmel-ecc - add support for ACPI probing on non-AT91 platformsArd Biesheuvel
The Atmel/Microchip EC508A is a I2C device that could be wired into any platform, and is being used on the Linaro/96boards Secure96 mezzanine adapter. This means it could be found on any platform, even on ones that use ACPI enumeration (via PRP0001 devices). So update the code to enable this use case. This involves tweaking the bus rate discovery code to take ACPI probing into account, which records the maximum bus rate as a property of the slave device. For the atmel-ecc code, this means that the effective bus rate should never exceed the maximum rate, unless we are dealing with buggy firmware. Nonetheless, let's just use the existing plumbing to discover the bus rate and keep the existing logic intact.

2019-05-30crypto: talitos - Do not modify req->cryptlen on decryption.Christophe Leroy
For decrypt, req->cryptlen includes the size of the authentication part while all functions of the driver expect cryptlen to be the size of the encrypted data. As it is not expected to change req->cryptlen, this patch implements local calculation of cryptlen.

2019-05-30crypto: talitos - check data blocksize in ablkcipher.Christophe Leroy
When data size is not a multiple of the alg's block size, the SEC generates an error interrupt and dumps the registers. And for NULL size, the SEC does just nothing and the interrupt is awaited forever. This patch ensures the data size is correct before submitting the request to the SEC engine.

SEC1 doesn't support SHA384/512, so it doesn't require longer keys. This patch reduces the max key size when the driver is built for SEC1 only.

The talitos driver has two ways to perform AEAD depending on the HW capability. Some HW support both.

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.

2019-05-23crypto: crypto4xx - block ciphers should only accept complete blocksChristian Lamparter
The hardware automatically zero pads incomplete block ciphers blocks without raising any errors. This is a screw-up. This was noticed by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS tests that sent a incomplete blocks and expect them to fail.

While the hardware consider them to be blockciphers, the reference implementation defines them as streamciphers. Do the right thing and set the blocksize to 1.

This patch fixes a issue with crypto4xx's ctr(aes) that was discovered by libcapi's kcapi-enc-test.sh test. The some of the ctr(aes) encryptions test were failing on the non-power-of-two test: kcapi-enc - Error: encryption failed with error 0 kcapi-enc - Error: decryption failed with error 0 [FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits): original file (1d100e..cc96184c) and generated file (e3b0c442..1b7852b855) [FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits) (openssl generated CT): original file (e3b0..5) and generated file (3..8e) [PASSED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits) (openssl generated PT) [FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (password): original file (1d1..84c) and generated file (e3b..852b855) But the 16, 32, 512, 65536 tests always worked. Thankfully, this isn't a hidden hardware problem like previously, instead this turned out to be a copy and paste issue. With this patch, all the tests are passing with and kcapi-enc-test.sh gives crypto4xx's a clean bill of health: "Number of failures: 0" :).

2019-05-23crypto: caam - print debugging hex dumps after unmappingSascha Hauer
For encryption the destination pointer was still mapped, so the hex dump may be wrong. The IV still contained the input IV while printing instead of the output IV as intended. For decryption the destination pointer was still mapped, so the hex dump may be wrong. The IV dump was correct. Do the hex dumps consistenly after the buffers have been unmapped and in case of IV copied to their final destination.
