da59c2e4 - [GWP-ASan] Change sys/cdefs.h to features.h

Thu, 18 Feb 2021 04:03:16 +0000

[GWP-ASan] Change sys/cdefs.h to features.hsys/cdefs.h is a glibc internal header which is not supposed to be included by applications.(Some libc implementations provide this file for compatibility.)Android features.h includes sys/cdefs.h, so we can include features.h instead.This change makes `ninja gwp_asan` build on musl.

90678f65 - [GWP-ASan] Abstract the thread local variables access

Mon, 26 Oct 2020 21:54:22 +0000

[GWP-ASan] Abstract the thread local variables accessIn a similar fashion to D87420 for Scudo, this CL introduces a way toget thread local variables via a platform-specific reserved TLS slot,since Fuchsia doesn't support ELF TLS from the libc itself.If needing to use this, a platform will have to define`GWP_ASAN_HAS_PLATFORM_TLS_SLOT` and provide `gwp_asan_platform_tls_slot.h`which will define a `uint64_t *getPlatformGwpAsanTlsSlot()` functionthat will return the TLS word of storage.I snuck in a couple of cleanup items as well, moving some staticfunctions to anonymous namespace for consistency.Differential Revision: https://reviews.llvm.org/D90195 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/utilities_posix.cpp

be8e4de7 - [GWP-ASan] Rework utilities (NFC)

Tue, 20 Oct 2020 18:15:52 +0000

[GWP-ASan] Rework utilities (NFC)Few changes wrt utilities:- split `Check` into a platform agnostic condition test and a platform specific termination, for which we introduce the function `die`.- add a platform agnostic `utilities.cpp` that gets the allocation alignment functions original in the platform specific file, as they are reusable by all platforms.Differential Revision: https://reviews.llvm.org/D89811 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/utilities_posix.cpp

[GWP-ASan] Cleanup (NFC)Cleaning up some of the GWP-ASan code base:- lots of headers didn't have the correct file name- adding `#ifdef` guard to `utilities.h`- correcting an `#ifdef` guard based on actual file name- removing an extra `;`- clang-format'ing the code (`-style=llvm`)Differential Revision: https://reviews.llvm.org/D89721 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/utilities_posix.cpp

5f2a74c8 - [GWP-ASan] Update alignment on Android.

Wed, 12 Feb 2020 23:24:55 +0000

[GWP-ASan] Update alignment on Android.Summary:Android has different alignment requirements. You can read more aboutthem here(https://cs.android.com/android/platform/superproject/+/master:bionic/tests/malloc_test.cpp;l=808),but the general gist is that for malloc(x <= 8), we do malloc(8), andfor everything else, we do 16-byte alignment.Reviewers: eugenis, morehouse, cferrisReviewed By: eugenis, morehouseSubscribers: #sanitizers, llvm-commits, pccTags: #sanitizers, #llvmDifferential Revision: https://reviews.llvm.org/D74364 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/utilities_posix.cpp

a6258684 - [GWP-ASan] Crash Handler API.

Wed, 05 Feb 2020 23:39:03 +0000

[GWP-ASan] Crash Handler API.Summary:Forewarning: This patch looks big in #LOC changed. I promise it's not that bad, it just moves a lot of content from one file to another. I've gone ahead and left inline comments on Phabricator for sections where this has happened.This patch: 1. Introduces the crash handler API (crash_handler_api.h). 2. Moves information required for out-of-process crash handling into an AllocatorState. This is a trivially-copied POD struct that designed to be recovered from a deceased process, and used by the crash handler to create a GWP-ASan report (along with the other trivially-copied Metadata struct). 3. Implements the crash handler API using the AllocatorState and Metadata. 4. Adds tests for the crash handler. 5. Reimplements the (now optionally linked by the supporting allocator) in-process crash handler (i.e. the segv handler) using the new crash handler API. 6. Minor updates Scudo & Scudo Standalone to fix compatibility. 7. Changed capitalisation of errors (e.g. /s/Use after free/Use After Free).Reviewers: cryptoad, eugenis, jfbReviewed By: eugenisSubscribers: merge_guards_bot, pcc, jfb, dexonsmith, mgorny, cryptoad, #sanitizers, llvm-commitsTags: #sanitizers, #llvmDifferential Revision: https://reviews.llvm.org/D73557 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/utilities_posix.cpp
