[PATCH backport for 4.14] tee: handle lookup of shm with reference count 0

by Jens Wiklander

commit dfd0743f1d9ea76931510ed150334d571fbab49d upstream. 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.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage. See https://docs.engineering.redhat.com/x/_wEZB for more details.
