* hwrng: meson - Remove unneeded platform MODULE_ALIASJavier Martinez Canillas2016-10-251-1/+0Star
| | | | | | | | | | | | | The Amlogic Meson is a DT-only platform, which means the devices are registered via OF and not using the legacy platform devices support. So there's no need to have a MODULE_ALIAS("platform:meson-rng") since the reported uevent MODALIAS to user-space will always be the OF one.

* crypto: engine - Handle the kthread worker using the new APIPetr Mladek2016-10-252-19/+13Star
| | | | | | | | | | | | | | | | | | | | | | | Use the new API to create and destroy the crypto engine kthread worker. The API hides some implementation details. In particular, kthread_create_worker() allocates and initializes struct kthread_worker. It runs the kthread the right way and stores task_struct into the worker structure. kthread_destroy_worker() flushes all pending works, stops the kthread and frees the structure. This patch does not change the existing behavior except for dynamically allocating struct kthread_worker and storing only the pointer of this structure. It is compile tested only because I did not find an easy way how to run the code. Well, it should be pretty safe given the nature of the change.

* hwrng: meson - Fix module autoload for OF registrationJavier Martinez Canillas2016-10-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | If the driver is built as a module, autoload won't work because the module alias information is not filled.

| | | | | | | | | | | | | | The AES implementation using pure NEON instructions relies on the generic AES key schedule generation routines, which store the round keys as arrays of 32-bit quantities stored in memory using native endianness. This means we should refer to these round keys using 4x4 loads rather than 16x1 loads. In addition, the ShiftRows tables are loading using a single scalar load, which is also affected by endianness, so emit these tables in the correct order depending on whether we are building for big endian or not.

* crypto: marvell - Don't break chain for computable last ahash requestsRomain Perier2016-10-211-16/+49
| | | | | | | | | | | | | | | | | Currently, the driver breaks chain for all kind of hash requests in order to don't override intermediate states of partial ahash updates. However, some final ahash requests can be directly processed by the engine, and so without intermediate state. This is typically the case for most for the HMAC requests processed via IPSec. This commits adds a TDMA descriptor to copy context for these of requests into the "op" dma pool, then it allow to chain these requests at the DMA level. The 'complete' operation is also updated to retrieve the MAC digest from the right location.

* crypto: marvell - Use an unique pool to copy results of requestsRomain Perier2016-10-214-24/+26
| | | | | | | | | | | | | So far, we used a dedicated dma pool to copy the result of outer IV for cipher requests. Instead of using a dma pool per outer data, we prefer use the op dma pool that contains all part of the request from the SRAM. Then, the outer data that is likely to be used by the 'complete' operation, is copied later. In this way, any type of result can be retrieved by DMA for cipher or ahash requests.

However, if a device variant is added for an IP block that has nothing to do with the OMAP platform, the message "OMAP Random Number Generator Ver" is displayed anyway.

* hwrng: omap - Remove global definition of hwrngRomain Perier2016-10-211-9/+14
| | | | | | | | | | | | | The omap-rng driver currently assumes that there will only ever be a single instance of an RNG device. For this reason, there is a statically allocated struct hwrng, with a fixed name. However, registering two struct hwrng with the same isn't accepted by the RNG framework, so we need to switch to a dynamically allocated struct hwrng, each using a different name. Then, we define the name of this hwrng to "dev_name(dev)", so the name of the data structure is unique per device.

It makes the driver simpler and moves the busy loop, that waits until enough data is generated, to the read function. We simplify this step by only checking the status of the engine, if there is data, we copy the data to the output buffer and the amout of copied data is returned to the caller, otherwise zero is returned. The hwrng core will re-call the read operation as many times as required until enough data has been copied.

| * befs: fix comment styleLuis de Bethencourt2016-10-081-7/+3Star
| | | | | | | | | | | | | | | | | | | | | | The description of befs_load_sb was confusing the kernel-doc system since, because it starts with /**, it thinks it will document the function with kernel-doc formatting. Which it isn't. Fix other comment style issues in the file while we are at it. Signed-off-by: Luis de Bethencourt <luisbg@osg.samsung.com> Signed-off-by: Salah Triki <salah.triki@gmail.com>
| * befs: add check for ag_shift in superblockLuis de Bethencourt2016-10-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | ag_shift and blocks_per_ag contain the same information in different ways, same as block_shift and block_size do. It is worth checking this two are consistent, but since blocks_per_ag isn't documented as mandatory to use some implementations of befs don't enforce this, so making it non-fatal if they don't match and just having it as a warning.

| | | | | | | | | | | | | | | | | | befs_dump_super_block() wasn't giving the inode_size information when dumping all elements of the superblock.
