[ Upstream commit 9e0caab8e0f96f0af7d1dd388e62f44184a75372 ]
The optee driver uses specific page table types to verify if a memory
region is normal. These types are not defined in nommu systems. Trying
to compile the driver in these systems results in a build error:linux/drivers/tee/optee/call.c: In function ‘is_normal_memory’:
linux/drivers/tee/optee/call.c:533:26: error: ‘L_PTE_MT_MASK’ undeclared
(first use in this function); did you mean ‘PREEMPT_MASK’?
return (pgprot_val(p) & L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;

Prior to this patch in optee_probe() when optee_enumerate_devices() was
called the struct optee was fully initialized. If
optee_enumerate_devices() returns an error optee_probe() is supposed to
clean up and free the struct optee completely, but will at this late
stage need to call optee_remove() instead. This isn't done and thus
freeing the struct optee prematurely.With this patch the call to optee_enumerate_devices() is done after
optee_probe() has returned successfully and in case
optee_enumerate_devices() fails everything is cleaned up with a call to
optee_remove().Fixes: c3fa24af9244 ("tee: optee: add TEE bus device enumeration support")

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.tee_shm_register()->optee_shm_unregister()->check_mem_type() uses provided
user pointers for vma lookups (via __check_mem_type()), which can only by
done with untagged pointers.Untag user pointers in this function.

To facilitate additional options to get_user_pages_fast() change the
singular write parameter to be gup_flags.This patch does not change any functionality. New functionality will
follow in subsequent patches.Some of the get_user_pages_fast() call sites were unchanged because they
already passed FOLL_WRITE or 0 for the write parameter.NOTE: It was suggested to change the ordering of the get_user_pages_fast()
arguments to ensure that callers were converted. This breaks the current
GUP call site convention of having the returned pages be the final
parameter. So the suggestion was rejected.Link: http://lkml.kernel.org/r/20190328084422.29911-4-ira.weiny@intel.com

Introduce a generic TEE bus driver concept for TEE based kernel drivers
which would like to communicate with TEE based devices/services. Also
add support in module device table for these new TEE based devices.In this TEE bus concept, devices/services are identified via Universally
Unique Identifier (UUID) and drivers register a table of device UUIDs
which they can support.So this TEE bus framework registers following apis:
- match(): Iterates over the driver UUID table to find a corresponding
match for device UUID. If a match is found, then this particular device
is probed via corresponding probe api registered by the driver. This
process happens whenever a device or a driver is registered with TEE
bus.
- uevent(): Notifies user-space (udev) whenever a new device is registered
on this bus for auto-loading of modularized drivers.Also this framework allows for device enumeration to be specific to
corresponding TEE implementation like OP-TEE etc.Signed-off-by: Sumit Garg

This bug occurs when:
- a new request arrives, one thread(let's call it A) is pending in
optee_supp_req() with req->busy is initial value false.- tee-supplicant is killed, then optee_supp_release() is called, this
function calls list_del(&req->link), and set supp->ctx to NULL. And
it also wake up process A.- process A continues, it firstly checks supp->ctx which is NULL,
then checks req->busy which is false, at last run list_del(&req->link).
This triggers double list_del() and results kernel panic.For solve this problem, we rename req->busy to req->in_queue, and
associate it with state of whether req is linked to supp->reqs. So we
can just only check req->in_queue to make decision calling list_del()
or not.Signed-off-by: Zhizhou Zhang

This change prevents userland from referencing TEE shared memory
outside the area initially allocated by its owner. Prior this change an
application could not reference or access memory it did not own but
it could reference memory not explicitly allocated by owner but still
allocated to the owner due to the memory allocation granule.Reported-by: Alexandre Jutras

Bump the file's refcount before moving the reference into the fd table,
not afterwards. The old code could drop the file's refcount to zero for a
short moment before calling get_file() via get_dma_buf().This code can only be triggered on ARM systems that use Linaro's OP-TEE.
