2024-06-25libsanitizer: add filtering of sleep intervals for BackgroundThread.Andrey Drobyshev4-1/+153
Previously sleep interval length of BackgroundThread was determined by a hardcoded value, thus limiting time resolution of dependent tools, such as Heap Profiler. This commit implements simple algorithm which remembers last several sleeps (namely 2), their durations and whether or not they were followed by some interesting events (i.e. delivery of some memory usage statistics). Then it tries to predict an optimal sleep length for the next time, changing it dynamically.

2024-06-25libsanitizer: re-implement heap profiler.Dmitriy Evgenevich Gonzha6-18/+335
In the previos heap profiler implementation HeapProfile instance was created every time BackgroundThread wanted to collect statistical data. This commit simply applies the singleton pattern: now there's only one HeapProfile object which can both decide wether it's time to collect the statistics and print profiling data.

2024-06-25[libsanitizer] Switch RISC-V 64 Virtual Address detection to dynamicSlava Barinov1-3/+2
Upstream sanitizers for riscv64 only support 39-bit address space accordingly to RISC-V 64 specification. But when executed under qemu-user-riscv64 on x86_64 host the address space bitness mismatches which leads to internal stack errors inside AddrInMem() checks. And the check fails correctly: x86_64 bit host kernel allocates the stack in High Mem segment like 0x7fe000000000 which just does not fit into the 39-bit memory model. This patch switches the sanitizer to dynamic detection of address space, which might formally violate the spec, but allows sanitized binaries to be executed under qemu-user-riscv64 on x86_64 host.

2024-05-09Remove redundant calls of MaybeMountProcFS and refactor it.Maxim Ostapenko1-7/+2
It seems that we have lots of redundant MaybeMountProcFS, in particular each mapped sanitized shared library calls it from AsanInitializer constructor. Remove redudant MaybeMountProcFS calls from AsanInitializer and __asan_init. Also, it seems that under qemu-aarch64 opening /proc/self/maps for reading might be very expensive, so replace OpenFile("/proc/self/maps", RdOnly) with FileExists("/proc/self/maps") in MaybeMountProcFS to avoid expensive calls.

This commit fixes undefined reference error from libasan.so: /lib/libasan.so: undefined reference to `lsan_check_in_progress' occurred due to ASan runtime embeds part of LSan runtime and misses lsan_check_in_progress symbol.

2024-05-09Add mmap/munmap interceptors.Maxim Ostapenko4-4/+60
Some allocators may use mmap for their local pools that may cause false positive reports because LSan currently doesn't intercept mmap call mainly due to its complexity (we don't know whether a particular mmap would contain live pointers). However for some cases (e.g. anonymous rw mmaps) we can guess that they would contain live pointers thus we can add them into root regions. Thus, now we intercept mmap/munmap calls, add anonymous rw mappings into root regions and call real mmap.
