Summary: Turn an ET_CHECK into an error return when encountering an unknown instruction type. Differential Revision: D52451743
Summary: Don't fail fatally if the .pte file contains an unknown type enum value. Discovered by lionhead fuzzing. Differential Revision: D52493415
Summary: Flatbuffer array fields can be missing, so we need to check for `nullptr` before calling `size()` on them. Discovered by lionhead fuzzing. Differential Revision: D52493423
Summary: Fail non-fatally when encountering an unknown/unhandled `ScalarType` in a `.pte` file. As part of this: - Move the "types not supported yet" logic out of `scalar_type_util` and into `tensor_parser`, since that decision is an aspect of the runtime and not a fundamental aspect of `ScalarType`. - Remove the now-duplicate `sizeof_scalar_type` function, which is the same as the exsting `elementSize` function. Before this diff, `sizeof_scalar_type` did the "unsupported" checks that have now moved. - Add an `isValid()` function to let users of `ScalarType` know whether a given enum value is legit. This makes it possible to avoid the fatal error when calling `elementSize` on a bad value. - Add unit tests for the new `isValid()`. Differential Revision: D52451738
Summary: Ensure that arg indices are in range before looking up values. Corrupted files with very large indices could cause arbitrary memory reads. Differential Revision: D52451739
Summary: Ensure that op indices are in range before looking up values. Corrupted files with very large indices could cause arbitrary memory reads. Also ensure that the chains array is present before calling `size()` on it. Differential Revision: D52451740
