Kees Cook d46e58ef77 lkdtm/bugs: Check that a per-task stack canary exists ... Introduce REPORT_STACK_CANARY to check for differing stack canaries between two processes (i.e. that an architecture is correctly implementing per-task stack canaries), using the task_struct canary as the hint to locate in the stack. Requires that one of the processes being tested not be pid 1.
