      mm: propagate error from stack expansion even for guard page · fee7e49d
      Linus Torvalds authored
      Jay Foad reports that the address sanitizer test (asan) sometimes gets
      confused by a stack pointer that ends up being outside the stack vma
      that is reported by /proc/maps.
      
      This happens due to an interaction between RLIMIT_STACK and the guard
      page: when we do the guard page check, we ignore the potential error
      from the stack expansion, which effectively results in a missing guard
      page, since the expected stack expansion won't have been done.
      
      And since /proc/maps explicitly ignores the guard page (commit
      d7824370: "mm: fix up some user-visible effects of the stack guard
      page"), the stack pointer ends up being outside the reported stack area.
      
      This is the minimal patch: it just propagates the error.  It also
      effectively makes the guard page part of the stack limit, which in turn
      measn that the actual real stack is one page less than the stack limit.
      
      Let's see if anybody notices.  We could teach acct_stack_growth() to
      allow an extra page for a grow-up/grow-down stack in the rlimit test,
      but I don't want to add more complexity if it isn't needed.
