While testing a patch on Solaris, which does not support split-stack, I
ran across a bug in the handling of caller-saved registers for the
garbage collector. For non-split-stack systems, runtime_mcall is
responsible for saving all caller-saved registers on the stack so that
the GC stack scan will see them. It does this by calling
__builtin_unwind_init and setting the g's gcnextsp field to point to the
current stack. The garbage collector then scans the stack from gcnextsp
to the top of stack.
Unfortunately, the code was setting gcnextsp to point to runtime_mcall's
argument, which meant that even though runtime_mcall was careful to
store all caller-saved registers on the stack, the GC never saw them.
This is, of course, only a problem if a value lives only in a
caller-saved register, and not anywhere else on the stack or heap. And
it is only a problem if that caller-saved register manages to make it
all the way down to runtime_mcall without being saved by any function on
the way. This is moderately unlikely but it turns out that the recent
changes to keep values on the stack when compiling the runtime package
caused it to happen for the local variable `s` in `notifyListWait` in
runtime/sema.go. That function calls goparkunlock which is simple
enough to not require all registers, and itself calls runtime_mcall. So
it was possible for `s` to be released by the GC before the goroutine
returned from goparkunlock, which eventually caused a dangling pointer
to be passed to releaseSudog.
This is not a problem on split-stack systems, which use
__splitstack_get_context, which saves a stack pointer low enough on the
stack to scan the registers saved by runtime_mcall.
