      vfs: fix dentry RCU to refcounting possibly sleeping dput() · e5c832d5
      Linus Torvalds authored
      This is the fix that the last two commits indirectly led up to - making
      sure that we don't call dput() in a bad context on the dentries we've
      looked up in RCU mode after the sequence count validation fails.
      This basically expands d_rcu_to_refcount() into the callers, and then
      fixes the callers to delay the dput() in the failure case until _after_
      we've dropped all locks and are no longer in an RCU-locked region.
      The case of 'complete_walk()' was trivial, since its failure case did
      the unlock_rcu_walk() directly after the call to d_rcu_to_refcount(),
      and as such that is just a pure expansion of the function with a trivial
      movement of the resulting dput() to after 'unlock_rcu_walk()'.
      In contrast, the unlazy_walk() case was much more complicated, because
      not only does convert two different dentries from RCU to be reference
      counted, but it used to not call unlock_rcu_walk() at all, and instead
      just returned an error and let the caller clean everything up in
      Happily, one of the dentries in question (called "parent" inside
      unlazy_walk()) is the dentry of "nd->path", which terminate_walk() wants
      a refcount to anyway for the non-RCU case.
      So what the new and improved unlazy_walk() does is to first turn that
      dentry into a refcounted one, and once that is set up, the error cases
      can continue to use the terminate_walk() helper for cleanup, but for the
      non-RCU case.  Which makes it possible to drop out of RCU mode if we
      actually hit the sequence number failure case.

      vfs: use lockred "dead" flag to mark unrecoverably dead dentries · 0d98439e
      Linus Torvalds authored
      This simplifies the RCU to refcounting code in particular.
      I was originally intending to leave this for later, but walking through
      all the dput() logic (see previous commit), I realized that the dput()
      "might_sleep()" check was misleadingly weak.  And I removed it as
      misleading, both for performance profiling and for debugging.
      However, the might_sleep() debugging case is actually true: the final
      dput() can indeed sleep, if the inode of the dentry that you are
      releasing ends up sleeping at iput time (see dentry_iput()).  So the
      problem with the might_sleep() in dput() wasn't that it wasn't true, it
      was that it wasn't actually testing and triggering on the interesting
      In particular, just about *any* dput() can indeed sleep, if you happen
      to race with another thread deleting the file in question, and you then
      lose the race to the be the last dput() for that file.  But because it's
      a very rare race, the debugging code would never trigger it in practice.
      Why is this problematic? The new d_rcu_to_refcount() (see commit
      : "vfs: reimplement d_rcu_to_refcount() using
      lockref_get_or_lock()") does a dput() for the failure case, and it does
      it under the RCU lock.  So potentially sleeping really is a bug.
      But there's no way I'm going to fix this with the previous complicated
      "lockref_get_or_lock()" interface.  And rather than revert to the old
      and crufty nested dentry locking code (which did get this right by
      delaying the reference count updates until they were verified to be
      safe), let's make forward progress.

      vfs: reorganize dput() memory accesses · 8aab6a27
      Linus Torvalds authored
      This is me being a bit OCD after all the dentry optimization work this
      merge window: profiles end up showing 'dput()' as a rather expensive
      operation, and there were two unrelated bad reasons for that.
      The first reason was reading d_lockref.count for debugging purposes,
      which touches the lockref cacheline (for reads) before really need to.
      More importantly, the debugging test in question is _wrong_, and has
      hidden bugs.  It's true that we can only sleep when the count goes down
      to zero, but the test as-is hides the much more subtle bug that happens
      if we race with somebody else deleting the file.
      Anyway we _will_ touch that cacheline, but let's do it for a write and
      in the right routine (ie in "lockref_put_or_lock()") which annotates the
      costs better.  So remove the misleading debug code.
      The other was an unnecessary access to the cacheline that contains the
      d_lru list, just to check whether we already were on the LRU list or
      not.  This is exactly what we have d_flags for, so that we can avoid
      touching extra cache lines for the common case.  So just add another bit
      for "is this dentry on the LRU".
      Finally, mark the tests properly likely/unlikely, so that the common
      fast-paths are dense in the instruction stream.
      This makes the profiles look much saner.

      lockref: add ability to mark lockrefs "dead" · e7d33bb5
      Linus Torvalds authored
      The only actual current lockref user (dcache) uses zero reference counts
      even for perfectly live dentries, because it's a cache: there may not be
      any users, but that doesn't mean that we want to throw away the dentry.
      At the same time, the dentry cache does have a notion of a truly "dead"
      dentry that we must not even increment the reference count of, because
      we have pruned it and it is not valid.
      Currently that distinction is not visible in the lockref itself, and the
      dentry cache validation uses "lockref_get_or_lock()" to either get a new
      reference to a dentry that already had existing references (and thus
      cannot be dead), or get the dentry lock so that we can then verify the
      dentry and increment the reference count under the lock if that
      verification was successful.
      That's all somewhat complicated.
      This adds the concept of being "dead" to the lockref itself, by simply
      using a count that is negative.  This allows a usage scenario where we
      can increment the refcount of a dentry without having to validate it,
      and pushing the special "we killed it" case into the lockref code.
      The dentry code itself doesn't actually use this yet, and it's probably
      too late in the merge window to do that code (the dentry_kill() code
      with its "should I decrement the count" logic really is pretty complex
      code), but let's introduce the concept at the lockref level now.

      The extra new ABS_xx values resulted in ABS_MAX no longer being a

      um: Cleanup SIGTERM handling · 91d44ff8
      Richard Weinberger authored
      Richard reported that some UML processes survive if the UML
      main process receives a SIGTERM.
      This issue was caused by a wrongly placed signal(SIGTERM, SIG_DFL)
      in init_new_thread_signals().
      It disabled the UML exit handler accidently for some processes.
      The correct solution is to disable the fatal handler for all
      UML helper threads/processes.
      Such that last_ditch_exit() does not get called multiple times
      and all processes can exit due to SIGTERM.

      um: Implement probe_kernel_read() · f75b1b1b
      Richard Weinberger authored
      UML needs it's own probe_kernel_read() to handle kernel
      mode faults correctly.
      The implementation uses mincore() on the host side to detect
      whether a page is owned by the UML kernel process.
      This fixes also a possible crash when sysrq-t is used.
      Starting with 3.10 sysrq-t calls probe_kernel_read() to
      read details from the kernel workers. As kernel worker are
      completely async pointers may turn NULL while reading them.

      Pull ARM SoC cleanups from Olof Johansson:
       "This branch contains code cleanups, moves and removals for 3.12.
        There's a large number of various cleanups, and a nice net removal of
        13500 lines of code.
        Highlights worth mentioning are:
         - A series of patches from Stephen Boyd removing the ARM local timer
         - Move of Qualcomm MSM IOMMU code to drivers/iommu.
         - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
           driver and switching over to the drivers/pwm one.
         - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
        There's also a move of a header file out of include/linux/i2c/ to
        platform_data, where it really belongs.  It touches mostly ARM
        platform code for include changes so we took it through our tree"

      Pull ARM SoC low-priority fixes from Olof Johansson:
       "This branch contains a handful of fixes for various platforms that
        weren't serious enough to be included in late 3.11-rc releases.  Most
        of them are for minor cleanups and cosmetic fixes.
