This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0 |
