When encoding a UUID as a sequence of bytes, the spec (https://www.ietf.org/rfc/rfc4122.txt) says that the u32, and two u16s should be represented big endian. Before this patch OPTEE always treated them natively. With this patch UUIDs are always converted to/from big endian when communicating with normal world.

When encoding a UUID as a sequence of bytes, the spec says that the u32, and two u16s should be represented big endian. OPTEE always treats them natively, which on all supported targets is little-endian.
For most use cases, such as the
ioctlinterface, it doesn't really matter, as long as both ends misinterpret the bytes the same way. This is more of a concern if they are being stored or communicated in this format however.The text was updated successfully, but these errors were encountered:
