2019-06-06crypto: atmel - Fix sparse endianness warningsHerbert Xu
The param2 member in atmel_i2c_cmd is supposed to be little-endian but was marked as u16. This patch changes it to a __le16 which reveals a missing endian swap in atmel_i2c_init_read_cmd. Another missing little-endian marking is also added in atmel_i2c_checksum. Fixes: 11105693fa05 ("crypto: atmel-ecc - introduce Microchip...")

2019-06-06crypto: caam - strip input without changing crypto requestIuliana Prodan
For rsa and pkcs1pad, CAAM expects an input of modulus size. For this we strip the leading zeros in case the size is more than modulus. This commit avoids modifying the crypto request while stripping zeros from input, to comply with the crypto API requirement. This is done by adding a fixup input pointer and length.

2019-06-06crypto: caam - fix pkcs1pad(rsa-caam, sha256) failure because of invalid inputIuliana Prodan
The problem is with the input data size sent to CAAM for encrypt/decrypt. Pkcs1pad is failing due to pkcs1 padding done in SW starting with0x01 instead of 0x00 0x01. CAAM expects an input of modulus size. For this we strip the leading zeros in case the size is more than modulus or pad the input with zeros until the modulus size is reached.

2019-06-06crypto: inside-secure - do not rely on the hardware last bit for result ↵Antoine Tenart
descriptors When performing a transformation the hardware is given result descriptors to save the result data. Those result descriptors are batched using a 'first' and a 'last' bit. There are cases were more descriptors than needed are given to the engine, leading to the engine only using some of them, and not setting the last bit on the last descriptor we gave. This causes issues were the driver and the hardware aren't in sync anymore about the number of result descriptors given (as the driver do not give a pool of descriptor to use for any transformation, but a pool of descriptors to use *per* transformation). This patch fixes it by attaching the number of given result descriptors to the requests, and by using this number instead of the 'last' bit found on the descriptors to process them.

Replace sg_nents_for_len by sg_nents when DMA mapping/unmapping buffers and when looping over the SG entries. This fix cases where the SG entries aren't used fully, which would in such cases led to using fewer SG entries than needed (and thus the engine wouldn't have access to the full input data and the result would be wrong).

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.

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: caam - print messages in caam_dump_sg at debug levelSascha Hauer
caam_dump_sg() is only compiled in when DEBUG is defined, hence the messages are debug messages. Remove the @level argument from caam_dump_sg() and print all messages at debug level. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-05-30crypto: caam - print debug messages at debug levelSascha Hauer
The CAAM driver used to put its debug messages inside #ifdef DEBUG and then prints the messages at KERN_ERR level. Replace this with proper functions printing at KERN_DEBUG level. The #ifdef DEBUG gets unnecessary when the right functions are used. This replaces: - print_hex_dump(KERN_ERR ...) inside #ifdef DEBUG with print_hex_dump_debug(...) - dev_err() inside #ifdef DEBUG with dev_dbg() - printk(KERN_ERR ...) inside #ifdef DEBUG with dev_dbg() Some parts of the driver use these functions already, so it is only consequent to use the debug function consistently.
