nit: I would avoid importing a class or a function from a module.
Import only the module instead to keep the name space clean and provide readers with more context on where its members come from. For example, readers don’t need to backtrack to see sleep is a function from time, as opposed to a function defined in the file. https://google.github.io/styleguide/pyguide.html#22-imports

Readers reading the tests should understand that these imports are used extensively throughout these particular tests. This is common across lots of PyTorch tests.

All feedback has been accounted for on this PR. I have moved this to PyTorch as a single commit (with attribution retained) so we can merge it and move on to the next phases. Further phase 1 tweaks can come as separate PRs of course. |

…#94297) Hi! I've been fuzzing different pytorch modules, and found a crash inside one of them. Specifically, I'm talking about a module that processes `script_call` rpc requests and a function `ScriptCall::fromIValues(std::vector<at::IValue>& ivalues)`. Running this test case causes a crash that occurs when `ivalues.back()` is called [script_call.cpp:90](https://github.com/pytorch/pytorch/blob/abc54f93145830b502400faa92bec86e05422fbd/torch/csrc/distributed/rpc/script_call.cpp#L90). The crash occurs because the vector `ivalues` is empty. All tests were performed on this pytorch version: [abc54f9](https://github.com/pytorch/pytorch/tree/abc54f93145830b502400faa92bec86e05422fbd) The provided patch checks if there are enough elements in the ivalues vector. ### How to reproduce 1. To reproduce the crash, use provided docker: [Dockerfile](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch) 2. Build the container: `docker build -t oss-sydr-fuzz-pytorch-reproduce .` 3. Copy crash file to the current directory: - [crash-9f76d4e37a2391136a4ce07d47269db1e063e4b4.zip](https://github.com/pytorch/pytorch/files/10674059/crash-9f76d4e37a2391136a4ce07d47269db1e063e4b4.zip) 4. Run the container: ``docker run --privileged --network host -v `pwd`:/homedir --rm -it oss-sydr-fuzz-pytorch-reproduce /bin/bash`` 5. And execute the binary: `/message_deserialize_fuzz /homedir/crash-9f76d4e37a2391136a4ce07d47269db1e063e4b4` After execution completes you will see this stacktrace: ```asan AddressSanitizer:DEADLYSIGNAL ================================================================= ==57==ERROR: AddressSanitizer: SEGV on unknown address (pc 0x0000008e7b19 bp 0x7ffd2fdded70 sp 0x7ffd2fddec40 T0) ==57==The signal is caused by a READ memory access. ==57==Hint: this fault was caused by a dereference of a high value address (see register values below).

…ytorch#94300) Hi! I've been fuzzing different pytorch modules, and found a crash inside one of them. Specifically, I'm talking about a module for unpickling and a function called `Unpickler::readInstruction()`. Running this function with provided crash file results in a crash, which occurs while calling `auto dict = stack_.at(dict_pos).toGenericDict();` [unpickler.cpp:561](https://github.com/pytorch/pytorch/blob/0e94fbc0c8ab1572c88159c1a4c397b6eb824c01/torch/csrc/jit/serialization/unpickler.cpp#L561). The crash occurs, because the index `dict_pos` is out of bounds (which itself happens because the stack size is 0). Besides this pull-request, there is another one related to unpickler hardening: pytorch#84343 All tests were performed on this pytorch version: [abc54f9](https://github.com/pytorch/pytorch/tree/abc54f93145830b502400faa92bec86e05422fbd) ### How to reproduce 1.

arguments() returns vector member of object returned by schema() call.
When object returned by schema() call is destroyed, the vector is deallocated as well,
it's lifetime isn't extended.
This issue detected while running `pytest -v test/mobile/test_lite_script_type.py -k test_nest_typing_namedtuple_custom_classtype` with ASAN.

…kler (pytorch#103667) Hi! I've been fuzzing different pytorch modules with with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch), and found a heap buffer overflow error that occures by incorrect loop condition in torch::jit::unpickler.cpp. This bug was found in several fuzzing targets: it can be triggered by `torch::jit::load()` method when loading a .pt model and by `torch::distributed::rpc::deserializeRequest()` method in RPC module. All found errors could be reproduced with provided docker: [Dockerfile](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch). ### PoC for deserealizeRequest():

…103969) Hi! We've been fuzzing torchvision project with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz). We've found a heap buffer overflow error at `source_range_serialization.cpp:73` in pytorch project. The error occurs because there is not check in `deserialize_source` that `text_table_` size can be less than `fnameIndex`. To prevent the error the corresponding check must be located. torchvision version: 9d0a93eee90bf7c401b74ebf9c8be80346254f15 pytorch version: 0f1621d OS: Ubuntu 20.04 How to reproduce 1. Build docker from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/torchvision) and run the container: sudo docker build -t oss-sydr-fuzz-torchvision . sudo docker run --privileged --rm -v `pwd`:/fuzz -it oss-sydr-fuzz-torchvision /bin/bash 2. Run the target on this input: [serialization-crash.txt](https://github.com/pytorch/pytorch/files/11819901/serialization-crash.txt) /encode_png_fuzz serialization-crash.txt 3. You will see the following output: ================================================================= ==13==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x60200055a630 at pc 0x0000010197b7

Hi! We've been fuzzing torchvision project with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz). We've found a SEGV error at address 0x0 at `vector.h:163` in pytorch third-party project flatbuffers. The error occurs because the `ivalues` field of flatbuffer module can be null, so the corresponding check must be inserted. torchvision version: 9d0a93eee90bf7c401b74ebf9c8be80346254f15 pytorch version: 0f1621d OS: Ubuntu 20.04 How to reproduce 1. Build docker from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/torchvision) and run the container: sudo docker build -t oss-sydr-fuzz-torchvision . sudo docker run --privileged --rm -v `pwd`:/fuzz -it oss-sydr-fuzz-torchvision /bin/bash 2. Run the target on this input: [malformed-module.txt](https://github.com/pytorch/pytorch/files/11879653/malformed-module.txt) /encode_png_fuzz malformed-module.txt 3. You will see the following output: AddressSanitizer:DEADLYSIGNAL ================================================================= ==1154==ERROR: AddressSanitizer: SEGV on unknown address

Hi! we've been fuzzing PyTorch project with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch). We've found a couple heap-buffer-overflows in `distributed/rpc` module. PyTorch version: pytorch@0f1621d OS: Ubuntu 20.04 ### How to reproduce 1. Build docker from this [Dockerfile](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch) and run the container. 2. Then run `message_deserialize-afl++` fuzzing target on provided crash-inputs

### Description Hi! We've been fuzzing `pytorch` with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz) and found error of out of bounds access in `torch::jit` module. pytorch version: 18bcf62 The error occurs in `import_source.cpp:560` when we get the type from the `assign.rhs()`. `assign.rhs()` has `Maybe` type, as well as `assign.type()`, so one of them can be not presented. According to [grammar](https://github.com/pytorch/pytorch/blob/22f93852a2664b3dc29544ac6a36f1ec52c6caa2/torch/csrc/jit/frontend/tree_views.h), we can have `Assign` statement, which `lhs` will be `Subscript`, `rhs` will be empty (`Maybe` type with no subtrees) and `type` will be presented. But in `import_source.cpp:560` we try to get `rhs` expression from the assignment with no check whether it is presented. This is example from the how to reproduce section from the testing input: ``` class Module(Module): __parameters__ = ["0", ] __buffers__ = [] __annotations__ = [] __annotations__["0"] : Tensor ``` When we parse the last statement of class definition, we set the type of `lhs` to `Subscript`, because the lookahead is `[` https://github.com/pytorch/pytorch/blob/76fb72e24a5a4a47ad1f50c5c94d5c0b7e703531/torch/csrc/jit/frontend/parser.cpp#L205-L207 Then in `parseAssignment` we get `maybeOp` and `type` depending on the next symbol (if it is `:`, we get only the type) https://github.com/pytorch/pytorch/blob/76fb72e24a5a4a47ad1f50c5c94d5c0b7e703531/torch/csrc/jit/frontend/parser.cpp#L437-L447 So after that, in `import_source.cpp:560`, parsing attributes, one of which is assignment with subscript type of `lhs`, we try to get type from `rhs` expression and out of bounds access occurs. To fix the error, we need to check whether the `rhs` or `type` are presented and get the type from corresponding expression. ### How to reproduce Build docker container from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch): ```bash $ sudo docker build -t oss-sydr-fuzz-pytorch ``` Run docker container: ```bash $ sudo docker run --rm --privileged -v `pwd`:/fuzz -it oss-sydr-fuzz-pytorch /bin/bash ``` Run the `load_fuzz` target on the [input.txt](https://github.com/pytorch/pytorch/files/12173962/input.txt) ```bash /load_fuzz input.txt ``` You will see the following output: ``` AddressSanitizer:DEADLYSIGNAL ================================================================= ==157==ERROR: AddressSanitizer: SEGV on unknown address (pc 0x00000c163764 bp 0x7ffee71d0070 sp 0x7ffee71d0050 T0) ==157==The signal is caused by a READ memory access. ==157==Hint: this fault was caused by a dereference of a high value address (see register values below).

Compiler behavior when non-zero offset is added to a null pointer is undefined and is a bad habit.
- When `lapackEig` is called with to estimate a workspace size, do not add matrix size to the W pointer.
- When `unpack_pivots_cpu_kernel` with zero `dim_size` exit early.
- When `topk_impl_loop` is called with `k` is zero, exit right away as output tensors are empty anyway.
- Ignore adding non-zero storage-offset in `TensorImpl::data_ptr_impl_impl`, which can be the case if tensor is created as `torch.empty(3)[4:]`.
- In `s_addmm_out_sparse_dense_worker` do not call `axpy` over an empty vector.
- In `_sparse_binary_op_intersection_kernel_impl` do skip computing `ptr_indices_dim` when `sparse_dim` is empty.
- Exit `grid_sample` forward/backward kernels earlier if either `input` or `grid` are empty tensors.

…108414) Hi! I've been fuzzing different pytorch modules with with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch), and found a heap buffer overflow error that occurs during Python object deserialization routine. Vector with `IValues` is verified to contain at least 3 elements, which are subsequently removed from vector. The rest of vector is passed further, where it is expected to contain at least one more element. The crash occurs on empty vector. Docker to reproduce found error: [Dockerfile](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch). ### PoC: [crash-6d634f38a76bfeaa1fffc9472e8ea7b88ee8e776.txt](https://github.com/pytorch/pytorch/files/12499089/crash-6d634f38a76bfeaa1fffc9472e8ea7b88ee8e776.txt) ### ASAN report ``` ==339647==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x604000105388 at pc 0x000000c2b3bc bp 0x7fffffffb8d0 sp 0x7fffffffb8c8 READ of size 4 at 0x604000105388 thread T0 #0 0xc2b3bb in c10::IValue::isString() const /pytorch/aten/src/ATen/core/ivalue.h:685:27 #1 0xc2b3bb in c10::IValue::toStringRef[abi:cxx11]() const /pytorch/aten/src/ATen/core/ivalue_inl.h:2308:3 #2 0x101ce65f in torch::distributed::rpc::SerializedPyObj::fromIValues(std::vector<c10::IValue, std::allocator<c10::IValue> >) /pytorch/torch/csrc/distributed/rpc/types.cpp:103:39 #3 0x1006a7a0 in torch::distributed::rpc::PythonRemoteCall::fromMessage(torch::distributed::rpc::Message const&) /pytorch/torch/csrc/distributed/rpc/python_remote_call.cpp:58:26 #4 0x101d02e1 in torch::distributed::rpc::deserializeRequest(torch::distributed::rpc::Message const&) /pytorch/torch/csrc/distributed/rpc/utils.cpp:111:14 #5 0x8db738 in LLVMFuzzerTestOneInput /message_deserialize.cc:192:27 #6 0x8d84cd in ExecuteFilesOnyByOne /AFLplusplus/utils/aflpp_driver/aflpp_driver.c:255:7 #7 0x8d82d8 in LLVMFuzzerRunDriver /AFLplusplus/utils/aflpp_driver/aflpp_driver.c #8 0x8d7e98 in main /AFLplusplus/utils/aflpp_driver/aflpp_driver.c:300:10 pytorch#9 0x7ffff7a37082 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x24082) (BuildId: 1878e6b475720c7c51969e69ab2d276fae6d1dee) pytorch#10 0x817c4d in _start (/message_deserialize_afl+0x817c4d) 0x604000105388 is located 8 bytes to the left of 48-byte region [0x604000105390,0x6040001053c0) allocated by thread T0 here: #0 0x8d54ca in operator new(unsigned long) /llvm-project-llvmorg-14.0.6/compiler-rt/lib/asan/asan_new_delete.cpp:95:3 SUMMARY: AddressSanitizer: heap-buffer-overflow /pytorch/aten/src/ATen/core/ivalue.h:685:27 in c10::IValue::isString() const ``` Pull Request resolved: pytorch#108414 Approved by: https://github.com/ezyang

…ry (pytorch#113207) This is the cheap and cheerful implementation, which is only enabled on TORCH_SHOW_CPP_STACKTRACES, because it *eagerly* symbolizes immediately at exception throw time, even if the exception will end up getting caught. It would be better to do this lazily and only symbolize when we try to print the exception, but that requires a more involved refactor of c10::Error that I don't feel like doing. Compare the output before: ``` frame #0: c10::Error::Error(c10::SourceLocation, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >) + 0x95 (0x7fa21b99d975 in /data/users/ezyang/c/pytorch/torch/lib/libc10.so) frame #1: c10::TensorImpl::throw_cannot_call_with_symbolic(char const*) const + 0x8d (0x7fa21b951269 in /data/users/ezyang/c/pytorch/torch/lib/libc10.so) frame #2: c10::TensorImpl::sizes_custom() const + 0x9f (0x7fa21b9770df in /data/users/ezyang/c/pytorch/torch/lib/libc10.so) frame #3: at::meta::structured_mm::meta(at::Tensor const&, at::Tensor const&) + 0x31e (0x7fa20a202a8e in /data/users/ezyang/c/pytorch/torch/lib/libtorch_cpu.so) frame #4: <unknown function> + 0x29f34de (0x7fa20b5f34de in /data/users/ezyang/c/pytorch/torch/lib/libtorch_cpu.so) frame #5: <unknown function> + 0x2a1fd8e (0x7fa20b61fd8e in /data/users/ezyang/c/pytorch/torch/lib/libtorch_cpu.so) frame #6: <unknown function> + 0x6b907b (0x7fa2142b907b in /data/users/ezyang/c/pytorch/torch/lib/libtorch_python.so) frame #7: <unknown function> + 0x6b6175 (0x7fa2142b6175 in /data/users/ezyang/c/pytorch/torch/lib/libtorch_python.so) ``` and after: ``` #4 c10::Error::Error(c10::SourceLocation, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >) from ??:0 #5 c10::TensorImpl::throw_cannot_call_with_symbolic(char const*) const from ??:0 #6 c10::TensorImpl::sizes_custom() const [clone .localalias] from TensorImpl.cpp:0 #7 at::meta::structured_mm::meta(at::Tensor const&, at::Tensor const&) from ??:0 #8 at::(anonymous namespace)::wrapper_Meta_mm_out_out(at::Tensor const&, at::Tensor const&, at::Tensor&) from RegisterMeta.cpp:0 pytorch#9 c10::impl::make_boxed_from_unboxed_functor<c10::impl::detail::WrapFunctionIntoFunctor_<c10::CompileTimeFunctionPointer<at::Tensor& (at::Tensor const&, at::Tensor const&, at::Tensor&), &at::(anonymous namespace)::wrapper_Meta_mm_out_out>, at::Tensor&, c10::guts::typelist::typelist<at::Tensor const&, at::Tensor const&, at::Tensor&> >, false>::call(c10::OperatorKernel*, c10::OperatorHandle const&, c10::DispatchKeySet, std::vector<c10::IValue, std::allocator<c10::IValue> >*) from RegisterMeta.cpp:0 ``` Signed-off-by: Edward Z.

… to hang (pytorch#115124) Let's see if it helps pytorch#114913 The issues on llvm are at llvm/llvm-project#55530 and llvm/llvm-project#69369. In my CI test, I saw the following process hanged: ``` /pytorch/pytorch/.lintbin/clang-tidy -p=/pytorch/pytorch/build --extra-arg -I/usr/lib/llvm-11/include/openmp --extra-arg

user may not know which line of code called collectives in a big code base. When debugging, we can print python-cpp stacktrace in case user call ``ProcessGroup.reduce`` instead of ``torch.distributed.reduce``
```

```
output (using _allgather_base as an example): one example python-part trace is ``all_gather_into_tensor from /data/users/weif/pytorch/torch/distributed/distributed_c10d.py:2838``

Initial version of the new API for ONNX exporter based on FX graphs.
Although it will be tagged as experimental, we will try our best to not make BC changes. Following updates will add behavior, but hopefully, not change existing ones.
The
testsfolder is a placeholder for unit tests, but it also serves as a repository of API usage. Refer toteststo see examples on how to use the proposed API.ps: the
nextfolder in which next versions of the API are going to be discussed before passing for review was directly merged on master to prevent unnecessary noise during review of the actual API to be reviewed. Next version, sayv2will start fromv1plus new APIs that are already drafted atnextfolder.
