[scudo] Skip building scudo standalone if sys/auxv.h can't be found Summary: Since commit c299d1981deaf822dfaa06c791f3158bd6801e20 scudo standalone can't be built without including sys/auxv.h. I do not have that file on my system, and my builds have failed when trying to simply build "all" runtimes. Assuming that "all" means "all possible given the current environment" we need to guard the setting of COMPILER_RT_HAS_SCUDO_STANDALONE=TRUE by first checking if sys/auxv.h can be found.

[CMake] Check for C++14 instead of C++11 Now that LLVM moved to C++14, `COMPILER_RT_HAS_STD_CXX11_FLAG` should become `COMPILER_RT_HAS_STD_CXX14_FLAG`.

We are correctly passing `-std=c++14`, but this got overwritten further down the invocation by the compiler-rt flags.

Fix the target specific "-msse3" flag check in CMake. NFC msse3 is a target dependent flag and must be guarded as check_cxx_compiler_flag() checks only for compiler error messages and ignores warnings. Earlier COMPILER_RT_HAS_MSSE3_FLAG is set to "TRUE" for all targets as clang emits warnings and the compilation spits unnecessary warnings for non-X86 targets.

[scudo] Separate hardware CRC32 routines Summary: As raised in D28304, enabling SSE 4.2 for the whole Scudo tree leads to the emission of SSE 4.2 instructions everywhere, while the runtime checks only applied to the CRC32 computing function. This patch separates the CRC32 function taking advantage of the hardware into its own file, and only enabled -msse4.2 for that file, if detected to be supported by the compiler. Another consequence of removing SSE4.2 globally is realizing that memcpy were not being optimized, which turned out to be due to the -fno-builtin in SANITIZER_COMMON_CFLAGS. So we now explicitely enable builtins for Scudo. The resulting assembly looks good, with some CALLs are introduced instead of the CRC32 code being inlined.

[scudo] Refactor of CRC32 and ARM runtime CRC32 detection Summary: ARM & AArch64 runtime detection for hardware support of CRC32 has been added via check of the AT_HWVAL auxiliary vector. Following Michal's suggestions in D28417, the CRC32 code has been further changed and looks better now. When compiled with full relro (which is strongly suggested to benefit from additional hardening), the weak symbol for computeHardwareCRC32 is read-only and the assembly generated is fairly clean and straight forward. As suggested, an additional optimization is to skip the runtime check if SSE 4.2 has been enabled globally, as opposed to only for scudo_crc32.cpp. scudo_crc32.h has no purpose anymore and was removed.

[compiler-rt][SystemZ] Work around ASAN failures via -fno-partial-inlining Since updating the SystemZ LLVM build bot system to Ubuntu 18.04, all bots are red due to two ASAN failures. It turns out these are triggered due to building the ASAN support libraries, in particular the interceptor routines using GCC 7. Specifically, at least on our platform, this compiler decides to "partially inline" some of those interceptors, creating intermediate stub routines like "__interceptor_recvfrom.part.321". These will show up in the backtraces at interception points, causing testsuite failures. As a workaround to get the build bots green again, this patch adds the -fno-partial-inlining command line option when building the common sanitizer support libraries on s390x, if that option is supported by the compiler. llvm-svn: 363679

Reapply "Try enabling -Wsuggest-override again, using add_compile_options instead of add_compile_definitions for disabling it in unittests/ directories." add_compile_options is more sensitive to its location in the file than add_definitions--it only takes effect for sources that are added after it. This updated patch ensures that the add_compile_options is done before adding any source files that depend on it. Using add_definitions caused the flag to be passed to rc.exe on Windows and thus broke Windows builds.

Move it back to header files so that it actually takes effect. But over the past 7 years we've accumulated whole lot of format string bugs of different types, so disable the warning with -Wno-format for now for incremental clean up. Among the bugs that it warns about are all kinds of bad things: - wrong sizes of arguments - missing/excessive arguments - printing wrong things (e.g. *ptr instead of ptr) - completely messed up format strings - security issues where external string is used as format Reviewed By: vitalybuka Differential Revision: https://reviews.llvm.org/D107977

This is definitely legal in C++, all compilers accept it, and I only have room for half of one language standard in my brain. - InstrProfilingValue.c(320): warning C4113: 'uint32_t (__cdecl *)()' differs in parameter lists from 'uint32_t (__cdecl *)(void)' Fix this with an explicit (void) in the prototype. - InstrProfilingMerge.c.obj : warning LNK4006: _VPMergeHook already defined in InstrProfilingMergeFile.c.obj; second definition ignored Last remaining warning.

However, if the target we're building compiler-rt for isn't supported by libc++, this will lead to a failure since libc++'s <stdint.h> includes <__config>, which performs various checks.

check_library_exists(dl dlopen "" COMPILER_RT_HAS_LIBDL)
Add descriptive names to sanitizer entries in /proc/self/maps. Helps debugging. This is done by creating a named shared memory region, unlinking it and setting up a private (i.e. copy-on-write) mapping of that instead of a regular anonymous mapping. I've experimented with regular (sparse) files, but they can not be scaled to the size of MSan shadow mapping, at least on Linux/X86_64 and ext3 fs. Controlled by a common flag, decorate_proc_maps, disabled by default. This patch has a few shortcomings: * not all mappings are annotated, especially in TSan. * our handling of memset() of shadow via mmap() puts small anonymous mappings inside larger named mappings, which looks ugly and can, in theory, hit the mapping number limit. llvm-svn: 238621

To fix this, detect the `execinfo` library in `cmake/config-ix.cmake`, and add it to the unit test link flags. Additionally, since the code in `sys::PrintStackTrace` makes use of `itaniumDemangle`, also add `-lLLVMDemangle`. (Note that this is more of a general problem with libLLVMSupport, but I'm looking for a quick fix now so it can be merged to the 8.0 branch.)

[XRay][compiler-rt] FDRLogWriter Abstraction Summary: This change introduces an `FDRLogWriter` type which is responsible for serialising metadata and function records to character buffers. This is the first step in a refactoring of the implementation of the FDR runtime to allow for more granular testing of the individual components of the implementation. The main contribution of this change is a means of hiding the details of how specific records are written to a buffer, and for managing the extents of these buffers. We make use of C++ features (templates and some metaprogramming) to reduce repetition in the act of writing out specific kinds of records to the buffer. In this process, we make a number of changes across both LLVM and compiler-rt to allow us to use the `Trace` abstraction defined in the LLVM project in the testing of the runtime implementation. This gives us a closer end-to-end test which version-locks the runtime implementation with the loading implementation in LLVM. We also allow using gmock in compiler-rt unit tests, by adding the requisite definitions in the `AddCompilerRT.cmake` module. We also add the terminfo library detection along with inclusion of the appropriate compiler flags for header include lookup. Finally, we've gone ahead and updated the FDR logging implementation to use the FDRLogWriter for the lowest-level record-writing details. Following patches will isolate the state machine transitions which manage the set-up and tear-down of the buffers we're using in multiple threads.

This solves an issue for the spack package manager, where we want to use the zlib installed by spack, and spack provides the CMAKE_PREFIX_PATH for it.

[CMake] Support platform building builtins without a full toolchain Summary: This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake. This patch contains the following specific changes: * Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake * Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake * Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64. This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

[CMake] Fix the value of `config.target_cflags` for non-macOS Apple platforms. Attempt #3. The main problem here is that `-*-version_min=` was not being passed to the compiler when building test cases. This can cause problems when testing on devices running older OSs because Clang would previously assume the minimum deployment target is the the latest OS in the SDK which could be much newer than what the device is running. Previously the generated value looked like this: `-arch arm64 -isysroot <path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk` With this change it now looks like: `-arch arm64 -stdlib=libc++ -miphoneos-version-min=8.0 -isysroot <path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk` This mirrors the setting of config.target_cflags on macOS. This change is made for ASan, LibFuzzer, TSan, and UBSan. To implement this a new `get_test_cflags_for_apple_platform()` function has been added that when given an Apple platform name and architecture returns a string containing the C compiler flags to use when building tests. This also calls a new helper function `is_valid_apple_platform()` that validates Apple platform names. This is the third attempt at landing the patch. The first attempt (r359305) had to be reverted (r359327) due to a buildbot failure. The problem was that calling `get_test_cflags_for_apple_platform()` can trigger a CMake error if the provided architecture is not supported by the current CMake configuration. Previously, this could be triggered by passing `-DCOMPILER_RT_ENABLE_IOS=OFF` to CMake. The root cause is that we were generating test configurations for a list of architectures without checking if the relevant Sanitizer actually supported that architecture. We now intersect the list of architectures for an Apple platform with `<SANITIZER>_SUPPORTED_ARCH` (where `<SANITIZER>` is a Sanitizer name) to iterate through the correct list of architectures. The second attempt (r363633) had to be reverted (r363779) due to a build failure. The failed build was using a modified Apple toolchain where the iOS simulator SDK was missing. This exposed a bug in the existing UBSan test generation code where it was assumed that `COMPILER_RT_ENABLE_IOS` implied that the toolchain supported both iOS and the iOS simulator. This is not true. This has been fixed by using the list `SANITIZER_COMMON_SUPPORTED_OS` for the list of supported Apple platforms for UBSan. For consistency with the other Sanitizers we also now intersect the list of architectures with UBSAN_SUPPORTED_ARCH. rdar://problem/50124489 Differential Revision: https://reviews.llvm.org/D61242 llvm-svn: 373405

[Compiler-RT] For arm64e test suites use the SDK version as the minimum deployment target. Previously we used the minimum deployment target used for the platform (e.g. iOS is 9.0). Unfortunately this leads to ABI incompatibilities with arm64e devices running newer OSs. In particular the following TSan test cases that used libcxx would fail due to the ABI mismatch. * Darwin/libcxx-shared-ptr-recursive.mm * Darwin/libcxx-shared-ptr-stress.mm * Darwin/libcxx-shared-ptr.mm * libcxx/std_shared_ptr.cpp Given that arm64e is not ABI stable we should ideally match the deployment target for sanitizer runtimes and their tests cases to the device when building for arm64e. Unfortunately having a mixed deployment target (based on architecture) isn't currently supported by the build system and is non-trivial to implement. As a stop-gap measure this patch changes the sanitizer test suites (but not the sanitizer runtimes themselves) to use a newer deployment target when targetting arm64e. The deployment target used for arm64e is the SDK version because this "should" match the OS version running on the target device (it is a configuration error to not match them). rdar://83080611

[tsan] CMake support for TSan on OS X Hi, this patch adds a CMake flag called `COMPILER_RT_ENABLE_TSAN_OSX`, which is off by default. If enabled, the build system will be building the OS X version of the TSan runtime library (called `libclang_rt.tsan_osx_dynamic.dylib`). I'll submit patches that fix OS X build errors shortly. This is part of an effort to port TSan to OS X, and it's one the very first steps. Don't expect TSan on OS X to actually work or pass tests at this point. llvm-svn: 251915

[XRay][compiler-rt][Darwin] Minimal XRay build support in Darwin This change is the first in a series of changes to get the XRay runtime building on macOS. This first allows us to build the minimal parts of XRay to get us started on supporting macOS development. These include: - CMake changes to allow targeting x86_64 initially. - Allowing for building the initialisation routines without `.preinit_array` support. - Use __sanitizer::SleepForMillis() to work around the lack of clock_nanosleep on macOS. - Deprecate the xray_fdr_log_grace_period_us flag, and introduce the xray_fdr_log_grace_period_ms flag instead, to use milliseconds across platforms.

[CMake] Refactor iOS simulator/device test configuration generation code for LibFuzzer. Summary: In order to do this `FUZZER_SUPPORTED_OS` had to be pulled out of `lib/fuzzer/CMakeLists.txt` and into the main config so we can use it from the `test/fuzzer/CMakeList.txt`. `FUZZER_SUPPORTED_OS` currently has the same value of `SANITIZER_COMMON_SUPPORTED_OS` which preserves the existing behaviour but this allows us in the future to adjust the supported platforms independent of `SANITIZER_COMMON_SUPPORTED_OS`. This mirrors the other sanitizers. For non-Apple platforms `FUZZER_SUPPORTED_OS` is not defined and surprisingly this was the behaviour before this patch because `SANITIZER_COMMON_SUPPORTED_OS` was actually empty. This appears to not matter right now because the functions that take an `OS` as an argument seem to ignore it on non-Apple platforms. While this change tries to be NFC it is technically not because we now generate an iossim config whereas previously we didn't. This seems like the right thing to do because the build system was configured to compile LibFuzzer for iossim but previously we weren't generating a lit test config for it. The device/simulator testing configs don't run by default anyway so this shouldn't break testing. This change relies on the get_capitalized_apple_platform() function added in a previous commit. rdar://problem/58798733 Reviewers: kubamracek, yln Subscribers: mgorny, #sanitizers, llvm-commits Tags: #sanitizers, #llvm Differential Revision: https://reviews.llvm.org/D73243

[CMake] Refactor iOS simulator/device test configuration generation code for LibFuzzer. Summary: In order to do this `FUZZER_SUPPORTED_OS` had to be pulled out of `lib/fuzzer/CMakeLists.txt` and into the main config so we can use it from the `test/fuzzer/CMakeList.txt`. `FUZZER_SUPPORTED_OS` currently has the same value of `SANITIZER_COMMON_SUPPORTED_OS` which preserves the existing behaviour but this allows us in the future to adjust the supported platforms independent of `SANITIZER_COMMON_SUPPORTED_OS`. This mirrors the other sanitizers. For non-Apple platforms `FUZZER_SUPPORTED_OS` is not defined and surprisingly this was the behaviour before this patch because `SANITIZER_COMMON_SUPPORTED_OS` was actually empty. This appears to not matter right now because the functions that take an `OS` as an argument seem to ignore it on non-Apple platforms. While this change tries to be NFC it is technically not because we now generate an iossim config whereas previously we didn't. This seems like the right thing to do because the build system was configured to compile LibFuzzer for iossim but previously we weren't generating a lit test config for it. The device/simulator testing configs don't run by default anyway so this shouldn't break testing. This change relies on the get_capitalized_apple_platform() function added in a previous commit. rdar://problem/58798733 Reviewers: kubamracek, yln Subscribers: mgorny, #sanitizers, llvm-commits Tags: #sanitizers, #llvm Differential Revision: https://reviews.llvm.org/D73243

[MemProf] Memory profiling runtime support See RFC for background: http://lists.llvm.org/pipermail/llvm-dev/2020-June/142744.html Follow on companion to the clang/llvm instrumentation support in D85948 and committed earlier. This patch adds the compiler-rt runtime support for the memory profiling. Note that much of this support was cloned from asan (and then greatly simplified and renamed). For example the interactions with the sanitizer_common allocators, error handling, interception, etc. The bulk of the memory profiling specific code can be found in the MemInfoBlock, MemInfoBlockCache, and related classes defined and used in memprof_allocator.cpp. For now, the memory profile is dumped to text (stderr by default, but honors the sanitizer_common log_path flag). It is dumped in either a default verbose format, or an optional terse format. This patch also adds a set of tests for the core functionality. Differential Revision: https://reviews.llvm.org/D87120

It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast. The following were implemented: - additional consistency checks on the allocation function parameters and on the heap chunks; - use of checksum protected chunk header, to detect corruption; - randomness to the allocator base; - delayed freelist (quarantine), to mitigate use after free and overall determinism. Additional mitigations are in the works.

[scudo] 32-bit and hardware agnostic support Summary: This update introduces i386 support for the Scudo Hardened Allocator, and offers software alternatives for functions that used to require hardware specific instruction sets. This should make porting to new architectures easier. Among the changes: - The chunk header has been changed to accomodate the size limitations encountered on 32-bit architectures. We now fit everything in 64-bit. This was achieved by storing the amount of unused bytes in an allocation rather than the size itself, as one can be deduced from the other with the help of the GetActuallyAllocatedSize function. As it turns out, this header can be used for both 64 and 32 bit, and as such we dropped the requirement for the 128-bit compare and exchange instruction support (cmpxchg16b). - Add 32-bit support for the checksum and the PRNG functions: if the SSE 4.2 instruction set is supported, use the 32-bit CRC32 instruction, and in the XorShift128, use a 32-bit based state instead of 64-bit. - Add software support for CRC32: if SSE 4.2 is not supported, fallback on a software implementation. - Modify tests that were not 32-bit compliant, and expand them to cover more allocation and alignment sizes. The random shuffle test has been deactivated for linux-i386 & linux-i686 as the 32-bit sanitizer allocator doesn't currently randomize chunks.

[Windows build] Use "DIA SDK" in sysroot This updates llvm/utils/sysroot.py to include the "DIA SDK" folder in the sysroot. It also updates the build to look for the DIA SDK there if a sysroot is set. This requires moving LLVM_WINSYSROOT to config-ix.cmake. For the GN build, I chose to pass a qualified path to diaguids in libs instead of pushing a config with a `/libpath:` flag. The former requires a GN with https://gn-review.googlesource.com/c/gn/+/12200, the latter requires D109624. The former is more like the cmake build, arguably a bit simpler, and it's easier to check for the wrong GN revision and easier to update GN. Differential Revision: https://reviews.llvm.org/D109708

[Sanitizers, CMake] Basic sanitizer Solaris support (PR 33274) Summary: This patch, on top of https://reviews.llvm.org/D40898, contains the build system changes necessary to enable the Solaris/x86 sanitizer port. The only issue of note is the libclang_rt.sancov_{begin, end} libraries: clang relies on the linker automatically defining __start_SECNAME and __stop_SECNAME labels for sections whose names are valid C identifiers. This is a GNU ld extension not present in the ELF gABI, also implemented by gold and lld, but not by Solaris ld. To work around this, I automatically link the sancov_{begin,end} libraries into every executable for now. There seems to be now way to build individual startup objects like crtbegin.o/crtend.o, so I've followed the lead of libclang_rt.asan-preinit which also contains just a single object.

[MemProf] Memory profiling runtime support See RFC for background: http://lists.llvm.org/pipermail/llvm-dev/2020-June/142744.html Follow on companion to the clang/llvm instrumentation support in D85948 and committed earlier. This patch adds the compiler-rt runtime support for the memory profiling. Note that much of this support was cloned from asan (and then greatly simplified and renamed). For example the interactions with the sanitizer_common allocators, error handling, interception, etc. The bulk of the memory profiling specific code can be found in the MemInfoBlock, MemInfoBlockCache, and related classes defined and used in memprof_allocator.cpp. For now, the memory profile is dumped to text (stderr by default, but honors the sanitizer_common log_path flag). It is dumped in either a default verbose format, or an optional terse format. This patch also adds a set of tests for the core functionality. Differential Revision: https://reviews.llvm.org/D87120

And no UBSAN_OPTIONS in general. * as simple as possible Minimal CPU and RAM overhead. * Source locations unnecessary in the presence of (split) debug info. * Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at. * above two items save 3% binary size. When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.

Protection against stack-based memory corruption errors using SafeStack: compiler-rt runtime support library This patch adds runtime support for the Safe Stack protection to compiler-rt (see http://reviews.llvm.org/D6094 for the detailed description of the Safe Stack). This patch is our implementation of the safe stack on top of compiler-rt. The patch adds basic runtime support for the safe stack to compiler-rt that manages unsafe stack allocation/deallocation for each thread. Original patch by Volodymyr Kuznetsov and others at the Dependable Systems Lab at EPFL; updates and upstreaming by myself. Differential Revision: http://reviews.llvm.org/D6096 llvm-svn: 239763

Cross-DSO control flow integrity (compiler-rt part). This is an initial version of the runtime cross-DSO CFI support library. It contains a number of FIXMEs, ex. it does not support the diagnostic mode nor dlopen/dlclose, but it works and can be tested. Diagnostic mode, in particular, would require some refactoring (we'd like to gather all CFI hooks in the UBSan library into one function so that we could easier pass the diagnostic information down to __cfi_check). It will be implemented later. Once the diagnostic mode is in, I plan to create a second test configuration to run all existing tests in both modes. For now, this patch includes only a few new cross-DSO tests. llvm-svn: 255695

[esan] EfficiencySanitizer base runtime library Summary: Adds the initial version of a runtime library for the new EfficiencySanitizer ("esan") family of tools. The library includes: + Slowpath code via callouts from the compiler instrumentation for each memory access. + Registration of atexit() to call finalization code. + Runtime option flags controlled by the environment variable ESAN_OPTIONS. The common sanitizer flags are supported such as verbosity and log_path. + An initial simple test. Still TODO: common code for libc interceptors and shadow memory mapping, and tool-specific code for shadow state updating.

[scudo] Initial standalone skeleton check-in Summary: This is the initial check-in for the Standalone version of Scudo. The project is initially going to live in scudo/standalone then will replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html for details. This initial CL is meant to lay out the project structure, of both code & tests, providing a minimal amount of functionalities, namely various definitions, some atomic helpers and an intrusive list. (empty.cc is just here to have a compilation unit, but will go away in the upcoming CLs). Initial support is restricted to Linux i386 & x86_64 in make files and will be extended once things land & work. We will grow organically from here, adding functionalities in limited amounts.

It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast. The following were implemented: - additional consistency checks on the allocation function parameters and on the heap chunks; - use of checksum protected chunk header, to detect corruption; - randomness to the allocator base; - delayed freelist (quarantine), to mitigate use after free and overall determinism.
