Kees Cook b10e117134 lkdtm/usercopy: Expand size of "out of frame" object ... [ Upstream commit f387e86d3a ] To be sufficiently out of range for the usercopy test to see the lifetime mismatch, expand the size of the "bad" buffer, which will let it be beyond current_stack_pointer regardless of stack growth direction. Paired with the recent addition of stack depth checking under CONFIG_HARDENED_USERCOPY=y, this will correctly start tripping again.
