2021-12-16tee: handle lookup of shm with reference count 0Jens Wiklander1-108/+66
Since the tee subsystem does not keep a strong reference to its idle shared memory buffers, it races with other threads that try to destroy a shared memory through a close of its dma-buf fd or by unmapping the memory. In tee_shm_get_from_id() when a lookup in teedev->idr has been successful, it is possible that the tee_shm is in the dma-buf teardown path, but that path is blocked by the teedev mutex. Since we don't have an API to tell if the tee_shm is in the dma-buf teardown path or not we must find another way of detecting this condition. Fix this by doing the reference counting directly on the tee_shm using a new refcount_t refcount field. dma-buf is replaced by using anon_inode_getfd() instead, this separates the life-cycle of the underlying file from the tee_shm. tee_shm_put() is updated to hold the mutex when decreasing the refcount to 0 and then remove the tee_shm from teedev->idr before releasing the mutex. This means that the tee_shm can never be found unless it has a refcount larger than 0.

2021-11-17optee: add asynchronous notificationsJens Wiklander4-36/+289
Adds support for asynchronous notifications from secure world to normal world. This allows a design with a top half and bottom half type of driver where the top half runs in secure interrupt context and a notifications tells normal world to schedule a yielding call to do the bottom half processing. The protocol is defined in optee_msg.h optee_rpc_cmd.h and optee_smc.h. A notification consists of a 32-bit value which normal world can retrieve using a fastcall into secure world. The value OPTEE_SMC_ASYNC_NOTIF_VALUE_DO_BOTTOM_HALF (0) has a special meaning. When this value is sent it means that normal world is supposed to make a yielding call OPTEE_MSG_CMD_DO_BOTTOM_HALF. Notification capability is negotiated while the driver is initialized. If both sides supports these notifications then they are enabled. An interrupt is used to notify the driver that there are asynchronous notifications pending. The maximum needed notification value is communicated at this stage. This allows scaling up when needed.

2021-11-17optee: separate notification functionsJens Wiklander8-91/+181
Renames struct optee_wait_queue to struct optee_notif and all related functions to optee_notif_*(). The implementation is changed to allow sending a notification from an atomic state, that is from the top half of an interrupt handler. Waiting for keys is currently only used when secure world is waiting for a mutex or condition variable. The old implementation could handle any 32-bit key while this new implementation is restricted to only 8 bits or the maximum value 255. A upper value is needed since a bitmap is allocated to allow an interrupt handler to only set a bit in case the waiter hasn't had the time yet to allocate and register a completion. The keys are currently only representing secure world threads which number usually are never even close to 255 so it should be safe for now. In future ABI updates the maximum value of the key will be communicated while the driver is initializing.

2021-10-18optee: isolate smc abiJens Wiklander8-1388/+1506
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.

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.

2021-03-30tee: optee: do not check memref size on return from Secure WorldJerome Forissier1-10/+0
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).
