Fixed in da5bb37.

add support for Null Tensors to functions

* * This patch enables SLEEF to be referenced with GNU's vector ABI. ** SLEEF library with GNU ABI is completely separated from the library with the existing API. The reason for doing this is that if I only expose the GNU ABI version and somehow rename it in the header, SLEEF cannot be used with glibc, which already has the functions with the same names. ** In this patch, 1 ULP functions are default. Functions that return two values (like sincos) are not included in the GNU ABI version of SLEEF. ** The ABI specification does not provide a way to systematically specify accuracy via the function name. If we are going to allow the compiler automatically choose a function according to the compiler options, this might be a problem. ** We need a new testing program to confirm if this implementation is correct. ** If this patch is accepted, I am planning to add the library with SVML and LLVM naming conventions in the same way. * This patch also enables make test to run on MSVC and Mac OSX. * iutneon32 now automatically enables flushtozero mode for tester * This patch fixes the following bugs. ** xsqrtf_u35 did not work correctly if compiled with VECEXT option ** iutsimd.c is now divided into two parts. This is needed to make it work with icc. In the previous implementation, the whole program is compiled with support for extended ISA (e.g. AVX512F), and this caused the IUT not to exit with the correct exit code when that ISA is not supported on the host. ** In tester, the reference ldexp function is now replaced with MPFR version. ** In tester2simddp.c, function vgeti was using syntax incompatible with MSVC. ** iutsimd did not work correctly if compiled with icc due to incorrect length of array in func_d_d_i macro. ** AVX512F is now enabled if GCC version is 5 or later * Edited Makefile under libm-tester so that it can be built in the Travis environment * sincos series functions and modf are now included in the gnuabi version of SLEEF.

* fix the oop fusion issue * add UT * lint * add linear cases * lint

…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: #84343 All tests were performed on this pytorch version: [abc54f9](https://github.com/pytorch/pytorch/tree/abc54f93145830b502400faa92bec86e05422fbd) ### 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-042dff5e121580425d9d34d0f293918f3c9fbf1e.zip](https://github.com/pytorch/pytorch/files/10674361/crash-042dff5e121580425d9d34d0f293918f3c9fbf1e.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_sydr /homedir/crash-042dff5e121580425d9d34d0f293918f3c9fbf1e` After execution completes you will see this error message: ```txt terminate called after throwing an instance of 'std::out_of_range' what(): vector::_M_range_check: __n (which is 18446744073709551613) >= this->size() (which is 0) ``` And this stacktrace: ```asan erminate called after throwing an instance of 'std::out_of_range' what(): vector::_M_range_check: __n (which is 18446744073709551613) >= this->size() (which is 0) ==39== ERROR: libFuzzer: deadly signal #0 0x5d0df1 in __sanitizer_print_stack_trace /llvm-project/compiler-rt/lib/asan/asan_stack.cpp:87:3 #1 0x545727 in fuzzer::PrintStackTrace() /llvm-project/compiler-rt/lib/fuzzer/FuzzerUtil.cpp:210:5 #2 0x52b933 in fuzzer::Fuzzer::CrashCallback() /llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp:233:3 #3 0x7f9118e0341f (/lib/x86_64-linux-gnu/libpthread.so.0+0x1441f) #4 0x7f9118c2300a in raise (/lib/x86_64-linux-gnu/libc.so.6+0x4300a) #5 0x7f9118c02858 in abort (/lib/x86_64-linux-gnu/libc.so.6+0x22858) #6 0x7f9119040910 (/lib/x86_64-linux-gnu/libstdc++.so.6+0x9e910) #7 0x7f911904c38b (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa38b) #8 0x7f911904c3f6 in std::terminate() (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa3f6) #9 0x7f911904c6a8 in __cxa_throw (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa6a8) #10 0x7f91190433aa (/lib/x86_64-linux-gnu/libstdc++.so.6+0xa13aa) #11 0x63acdf in std::vector<c10::IValue, std::allocator<c10::IValue> >::_M_range_check(unsigned long) const /usr/bin/../lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/bits/stl_vector.h:1073:4 #12 0xce8f93e in std::vector<c10::IValue, std::allocator<c10::IValue> >::at(unsigned long) /usr/bin/../lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/bits/stl_vector.h:1094:2 #13 0xce8f93e in torch::jit::Unpickler::readInstruction() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:546:26 #14 0xce8d527 in torch::jit::Unpickler::run() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:235:27 #15 0xce8d1c2 in torch::jit::Unpickler::parse_ivalue() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:192:3 #16 0xcdf0792 in torch::jit::unpickle(std::function<unsigned long (char*, unsigned long)>, std::function<c10::StrongTypePtr (c10::QualifiedName const&)>, c10::ArrayRef<at::Tensor>, c10::Type::SingletonOrSharedTypePtr<c10::Type> (*)(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)) /pytorch_fuzz/torch/csrc/jit/serialization/pickle.cpp:127:20 #17 0xcdf104d in torch::jit::unpickle(char const*, unsigned long, std::function<c10::StrongTypePtr (c10::QualifiedName const&)>, c10::ArrayRef<at::Tensor>, c10::Type::SingletonOrSharedTypePtr<c10::Type> (*)(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)) /pytorch_fuzz/torch/csrc/jit/serialization/pickle.cpp:137:10 #18 0xe0532db in torch::distributed::rpc::ScriptRemoteCall::fromMessage(torch::distributed::rpc::Message const&) /pytorch_fuzz/torch/csrc/distributed/rpc/script_remote_call.cpp:74:16 #19 0xe0ffa10 in torch::distributed::rpc::deserializeRequest(torch::distributed::rpc::Message const&) /pytorch_fuzz/torch/csrc/distributed/rpc/utils.cpp:108:14 #20 0x602a41 in LLVMFuzzerTestOneInput /message_deserialize_fuzz.cc:192:27 #21 0x52ce61 in fuzzer::Fuzzer::ExecuteCallback(unsigned char const*, unsigned long) /llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp:611:15 #22 0x516d7c in fuzzer::RunOneTest(fuzzer::Fuzzer*, char const*, unsigned long) /llvm-project/compiler-rt/lib/fuzzer/FuzzerDriver.cpp:324:6 #23 0x51cacb in fuzzer::FuzzerDriver(int*, char***, int (*)(unsigned char const*, unsigned long)) /llvm-project/compiler-rt/lib/fuzzer/FuzzerDriver.cpp:860:9 #24 0x546062 in main /llvm-project/compiler-rt/lib/fuzzer/FuzzerMain.cpp:20:10 #25 0x7f9118c04082 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x24082) #26 0x51169d in _start (/message_deserialize_fuzz+0x51169d) NOTE: libFuzzer has rudimentary signal handlers.

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

#126677) …destruction of tensors cached by autocast ## Root Cause For out-of-tree device extension it is loaded after torch (different .so), so the global variable `cached_casts` may be constructed before caching allocator and then destructed in reversed order when exit. ## Fix Lazily initialize `cached_casts` to correct the order. ## How to Reproduce && Test Modify the testcase `TestAutocastGPU.test_cast_cache_is_global` in test/test_autocast.py to run on your out-of-tree device. You will see following failure in the end of test. ```bash ---------------------------------------------------------------------- Ran 1 test in 4.812s OK free: 0x30080ff44000400 terminate called after
