2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers
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.

2020-11-09tee: amdtee: fix memory leak due to reset of global shm listRijo Thomas
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.

2020-08-25tee: convert get_user_pages() --> pin_user_pages()John Hubbard
This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages*() + put_page() calls to pin_user_pages*() + unpin_user_pages() calls. Factor out a new, small release_registered_pages() function, in order to consolidate the logic for discerning between TEE_SHM_USER_MAPPED and TEE_SHM_KERNEL_MAPPED pages. This also absorbs the kfree() call that is also required there. There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

REE kernel is expected to formulate trustworthy client UUID and pass that to TEE environment. REE kernel is required to verify that provided group identifier for group based logins matches calling processes group memberships. TEE specification only defines that the information passed from REE environment to TEE environment is encoded into on UUID. In order to guarantee trustworthiness of client UUID user space is not allowed to freely pass client UUID. UUIDv5 form is used encode variable amount of information needed for different login types.

2020-04-20tee: add private login method for kernel clientsSumit Garg
There are use-cases where user-space shouldn't be allowed to communicate directly with a TEE device which is dedicated to provide a specific service for a kernel client. So add a private login method for kernel clients and disallow user-space to open-session using GP implementation defined login method range: (0x80000000 - 0xBFFFFFFF).
