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/test/gwp_asan/double_free.cpp Wed, 05 Feb 2020 23:39:03 +0000 Mitch Phillips <31459023+hctim@users.noreply.github.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/gwp_asan/double_free.cpp#7339ca27 [GWP-ASan] Add generic unwinders and structure backtrace output.Summary:Adds two flavours of generic unwinder and all the supporting cruft. If thesupporting allocator is okay with bringing in sanitizer_common, they can usethe fast frame-pointer based unwinder from sanitizer_common. Otherwise, we alsoprovide the backtrace() libc-based unwinder as well. Of course, the allocatorcan always specify its own unwinder and unwinder-symbolizer.The slightly changed output format is exemplified in the first comment on thispatch. It now better incorporates backtrace information, and displaysallocation details on the second line.Reviewers: eugenis, vlad.tsyrklevichReviewed By: eugenis, vlad.tsyrklevichSubscribers: srhines, kubamracek, mgorny, cryptoad, #sanitizers, llvm-commits, morehouseTags: #sanitizers, #llvmDifferential Revision: https://reviews.llvm.org/D63841llvm-svn: 364941 List of files: /llvm-project-15.0.7/compiler-rt/test/gwp_asan/double_free.cpp Tue, 02 Jul 2019 16:04:52 +0000 Mitch Phillips <mitchphillips@outlook.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/gwp_asan/double_free.cpp#21184ec5 [GWP-ASan] Integration with Scudo [5].Summary:See D60593 for further information.This patch adds GWP-ASan support to the Scudo hardened allocator. It alsoimplements end-to-end integration tests using Scudo as the backing allocator.The tests include crash handling for buffer over/underflow as well asuse-after-free detection.Reviewers: vlad.tsyrklevich, cryptoadReviewed By: vlad.tsyrklevich, cryptoadSubscribers: kubamracek, mgorny, #sanitizers, llvm-commits, morehouseTags: #sanitizers, #llvmDifferential Revision: https://reviews.llvm.org/D62929llvm-svn: 363584 List of files: /llvm-project-15.0.7/compiler-rt/test/gwp_asan/double_free.cpp Mon, 17 Jun 2019 17:45:34 +0000 Mitch Phillips <mitchphillips@outlook.com>
