f18397ab3a tee: fix put order in teedev_close_context()
Prior to this patch was teedev_close_context() calling tee_device_put()
before teedev_ctx_put() leading to teedev_ctx_release() accessing
ctx->teedev just after the reference counter was decreased on the
teedev. Fix this by calling teedev_ctx_put() before tee_device_put().

5c904c66ed Char/Misc driver update for 5.16-rc1
Here is the big set of char and misc and other tiny driver subsystem
 updates for 5.16-rc1.
 
 Loads of things in here, all of which have been in linux-next for a
 while with no reported problems (except for one called out below.)
 
 Included are:
 	- habanana labs driver updates, including dma_buf usage,
 	  reviewed and acked by the dma_buf maintainers
 	- iio driver update (going through this tree not staging as they
 	  really do not belong going through that tree anymore)
 	- counter driver updates
 	- hwmon driver updates that the counter drivers needed, acked by
 	  the hwmon maintainer
 	- xillybus driver updates
 	- binder driver updates
 	- extcon driver updates
 	- dma_buf module namespaces added (will cause a build error in
 	  arm64 for allmodconfig, but that change is on its way through
 	  the drm tree)
 	- lkdtm driver updates
 	- pvpanic driver updates
 	- phy driver updates
 	- virt acrn and nitr_enclaves driver updates
 	- smaller char and misc driver updates

Adds support for using FF-A [1] as transport to the OP-TEE driver.

Introduces struct optee_msg_param_fmem which carries all information
needed when OP-TEE is calling FFA_MEM_RETRIEVE_REQ to get the shared
memory reference mapped by the hypervisor in S-EL2. Register usage is
also updated to include the information needed.

The FF-A part of this driver is enabled if CONFIG_ARM_FFA_TRANSPORT is
enabled.

c51a564a5b optee: isolate smc abi
Isolate the ABI based on raw SMCs. Code specific to the raw SMC ABI is
moved into smc_abi.c. This makes room for other ABIs with a clear
separation.

The driver changes to use module_init()/module_exit() instead of
module_platform_driver(). The platform_driver_register() and
platform_driver_unregister() functions called directly to keep the same
behavior. This is needed because module_platform_driver() is based on
module_driver() which can only be used once in a module.

A function optee_rpc_cmd() is factored out from the function
handle_rpc_func_cmd() to handle the ABI independent part of RPC
processing.

This patch is not supposed to change the driver behavior, it's only a
matter of reorganizing the code.

4602c5842f optee: refactor driver with internal callbacks
The OP-TEE driver is refactored with three internal callbacks replacing
direct calls to optee_from_msg_param(), optee_to_msg_param() and
optee_do_call_with_arg().

These functions a central to communicating with OP-TEE in secure world
by using the SMC Calling Convention directly.

This refactoring makes room for using other primitives to communicate
with OP-TEE in secure world while being able to reuse as much as
possible from the present driver.

376e4199e3 tee: Correct inappropriate usage of TEE_SHM_DMA_BUF flag
Currently TEE_SHM_DMA_BUF flag has been inappropriately used to not
register shared memory allocated for private usage by underlying TEE
driver: OP-TEE in this case. So rather add a new flag as TEE_SHM_PRIV
that can be utilized by underlying TEE drivers for private allocation
and usage of shared memory.

With this corrected, allow tee_shm_alloc_kernel_buf() to allocate a
shared memory region without the backing of dma-buf.

b5c10dd04b optee: Clear stale cache entries during initialization
The shm cache could contain invalid addresses if
optee_disable_shm_cache() was not called from the .shutdown hook of the
previous kernel before a kexec. These addresses could be unmapped or
they could point to mapped but unintended locations in memory.

Clear the shared memory cache, while being careful to not translate the
addresses returned from OPTEE_SMC_DISABLE_SHM_CACHE, during driver
initialization. Once all pre-cache shm objects are removed, proceed with
enabling the cache so that we know that we can handle cached shm objects
with confidence later in the .shutdown hook.

Make kernel dump collection more reliable on systems utilizing OP-TEE by
refusing to load the driver under the kdump kernel.

673c7aa243 optee: use export_uuid() to copy client UUID
Prior to this patch optee_open_session() was making assumptions about
the internal format of uuid_t by casting a memory location in a
parameter struct to uuid_t *. Fix this using export_uuid() to get a well
defined binary representation and also add an octets field in struct
optee_msg_param in order to avoid casting.

Same Trusted Application (TA) can be loaded in multiple TEE contexts.

If it is a single instance TA, the TA should not get unloaded from AMD
Secure Processor, while it is still in use in another TEE context.

Therefore reference count TA and unload it when the count becomes zero.

c650b8dc7a tee: optee: do not check memref size on return from Secure World
When Secure World returns, it may have changed the size attribute of the
memory references passed as [in/out] parameters. The GlobalPlatform TEE
Internal Core API specification does not restrict the values that this
size can take. In particular, Secure World may increase the value to be
larger than the size of the input buffer to indicate that it needs more.

Therefore, the size check in optee_from_msg_param() is incorrect and
needs to be removed. This fixes a number of failed test cases in the
GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09
when OP-TEE is compiled without dynamic shared memory support
(CFG_CORE_DYN_SHM=n).

67bc809752 optee: simplify i2c access
Storing a bogus i2c_client structure on the stack adds overhead and
causes a compile-time warning:

drivers/tee/optee/rpc.c:493:6: error: stack frame size of 1056 bytes in function 'optee_handle_rpc' [-Werror,-Wframe-larger-than=]
void optee_handle_rpc(struct tee_context *ctx, struct optee_rpc_param *param,

Change the implementation of handle_rpc_func_cmd_i2c_transfer() to
open-code the i2c_transfer() call, which makes it easier to read
and avoids the warning.

48c1c40ab4 ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

853735e404 optee: add writeback to valid memory type
Only in smp systems the cache policy is setup as write alloc, in
single cpu systems the cache policy is set as writeback and it is
normal memory, so, it should pass the is_normal_memory check in the
share memory registration.

Add the right condition to make it work in no smp systems.

a24d22b225 crypto: sha - split sha.h into sha1.h and sha2.h
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.

This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure.  So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.

Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.

This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1.  It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

ff1f855804 tee: amdtee: fix memory leak due to reset of global shm list
The driver maintains a list of shared memory buffers along with their
mapped buffer id's in a global linked list. These buffers need to be
unmapped after use by the user-space client.

The global shared memory list is initialized to zero entries in the
function amdtee_open(). This clearing of list entries can be a source
for memory leak on secure side if the global linked list previously
held some mapped buffer entries allocated from another TEE context.

Fix potential memory leak issue by moving global shared memory list
to AMD-TEE driver context data structure.
