* Add descriptive names to sanitizer entries in /proc/self/maps. Helps debugging.Evgeniy Stepanov2015-05-2920-54/+166
| | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@238621 91177308-0d34-0410-b5e6-96231b3b80d8

* [msan] Mprotect all inaccessible memory regions.Evgeniy Stepanov2015-05-244-12/+75
| | | | | | | | | | | | | | | | | | Fix 2 bugs in memory mapping setup: - the invalid region at offset 0 was not protected because mmap at address 0 fails with EPERM on most Linux systems. We did not notice this because the check condition was flipped: the code was checking that mprotect has failed. And the test that was supposed to catch this was weakened by the mitigations in the mmap interceptor. - when running without origins, the origin shadow range was left unprotected. The new test ensures that mmap w/o MAP_FIXED always returns valid application addresses. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@238109 91177308-0d34-0410-b5e6-96231b3b80d8
