[release-branch.go1.11] runtime: fix write barrier on wasm

2019-03-19T21:24:41Z

The current wasm write barrier implementation incorrectly implements the "deletion" part of the barrier. It correctly greys the new value of the pointer, but rather than also greying the old value of the pointer, it greys the object containing the slot (which, since the old value was just overwritten, is not going to contain the old value). This can lead to unmarked, reachable objects. Often, this is masked by other marking activity, but one specific sequence that can lead to an unmarked object because of this bug is: 1. Initially, GC is off, object A is reachable from just one pointer in the heap. 2. GC starts and scans the stack of goroutine G. 3. G copies the pointer to A on to its stack and overwrites the pointer to A in the heap. (Now A is reachable only from G's stack.) 4. GC finishes while A is still reachable from G's stack. With a functioning deletion barrier, step 3 causes A to be greyed. Without a functioning deletion barrier, nothing causes A to be greyed, so A will be freed even though it's still reachable from G's stack. This CL fixes the wasm write barrier. Fixes #30872.
