secure_storage: use private buffers #78

Closed jforissier closed 3 years ago

jforissier commented 3 years ago

TEE_ReadObjectData() and TEE_WriteObjectData() data buffers have [out] and [in] attributes and therefore "SHALL not reside in a block of shared memory owned by a client of the Trusted Application" [1]. Fix this by allocating temporary buffers from the heap.
