sigreturn via vdso is missed

Open stephenrkell opened this issue 3 years ago • 0 comments

Since we don't want to catch sigreturns, this is serendipitous in a way. But it's a problem that they sneak through the 'real' vDSO rather than our fake one. Not sure how this is happening... kernel sets pretcode pointing there by default, perhaps? In 32-bit mode.
