      mm: propagate error from stack expansion even for guard page · fee7e49d
      Linus Torvalds 提交于
      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.

      nios2: Use preempt_schedule_irq · 1b0f4492
      Tobias Klauser 提交于
      Follow aa0d5326 ("ia64: Use preempt_schedule_irq") and use
      preempt_schedule_irq instead of enabling/disabling interrupts and
      messing around with PREEMPT_ACTIVE in the nios2 low-level preemption
      code ourselves. Also get rid of the now needless re-check for
      TIF_NEED_RESCHED, preempt_schedule_irq will already take care of
      rescheduling.
      
      This also fixes the following build error when building with
      CONFIG_PREEMPT:

      Revert "cfg80211: make WEXT compatibility unselectable" · 831a39c2
      Jiri Kosina 提交于
      This reverts commit 24a0aa21.
      
      It's causing severe userspace breakage.  Namely, all the utilities from
      wireless-utils which are relying on CONFIG_WEXT (which means tools like
      'iwconfig', 'iwlist', etc) are not working anymore.  There is a 'iw'
      utility in newer wireless-tools, which is supposed to be a replacement
      for all the "deprecated" binaries, but it's far away from being
      massively adopted.
      
      Please see [1] for example of the userspace breakage this is causing.
      
      In addition to that, Larry Finger reports [2] that this patch is also
      causing ipw2200 driver being impossible to build.
      
      To me this clearly shows that CONFIG_WEXT is far, far away from being
      "deprecated enough" to be removed.

      SCSI: fix regression in scsi_send_eh_cmnd() · 511833ac
      Alan Stern 提交于
      Commit ac61d195 (scsi: set correct completion code in
      scsi_send_eh_cmnd()) introduced a bug.  It changed the stored return
      value from a queuecommand call, but it didn't take into account that
      the return value was used again later on.  This patch fixes the bug by
      changing the later usage.
      
      There is a big comment in the middle of scsi_send_eh_cmnd() which
      does a good job of explaining how the routine works.  But it mentions
      a "rtn = FAILURE" value that doesn't exist in the code.  This patch
      adjusts the code to match the comment (I assume the comment is right
      and the code is wrong).
      
      This fixes Bugzilla #88341.
