2014-11-06UBSan: Teach isDerivedFromAtOffset and findBaseAtOffset about vbasesDavid Majnemer
When the __virtual_mask is set, __offset_flags >> __offset_shift yields an offset into the vtable. Dereferencing this vtable slot gets us the vbase offset. Adjust a test case to verify that this, in fact, works.

2014-10-13Sanitize upcasts and conversion to virtual base.Alexey Samsonov
This change adds UBSan check to upcasts. Namely, when we perform derived-to-base conversion, we: 1) check that the pointer-to-derived has suitable alignment and underlying storage, if this pointer is non-null. 2) if vptr-sanitizer is enabled, and we perform conversion to virtual base, we check that pointer-to-derived has a matching vptr. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@219642 91177308-0d34-0410-b5e6-96231b3b80d8

2014-09-17PR20721: Don't let UBSan print inaccessible memoryAlexey Samsonov
Summary: UBSan needs to check if memory snippet it's going to print resides in addressable memory. Similar check might be helpful in ASan with dump_instruction_bytes option (see http://reviews.llvm.org/D5167). Instead of scanning /proc/self/maps manually, delegate this check to the OS kernel: try to write this memory in a syscall and assume that memory is inaccessible if the syscall failed (e.g. with EFAULT).

2014-09-08Implement nonnull-attribute sanitizerAlexey Samsonov
Summary: This patch implements a new UBSan check, which verifies that function arguments declared to be nonnull with __attribute__((nonnull)) are actually nonnull in runtime. To implement this check, we pass FunctionDecl to CodeGenFunction::EmitCallArgs (where applicable) and if function declaration has nonnull attribute specified for a certain formal parameter, we compare the corresponding RValue to null as soon as it's calculated.
