      tmpfs mempolicy: fix /proc/mounts corrupting memory · f2a07f40
      Hugh Dickins authored
      Recently I suggested using "mount -o remount,mpol=local /tmp" in NUMA
      mempolicy testing.  Very nasty.  Reading /proc/mounts, /proc/pid/mounts
      or /proc/pid/mountinfo may then corrupt one bit of kernel memory, often
      in a page table (causing "Bad swap" or "Bad page map" warning or "Bad
      pagetable" oops), sometimes in a vm_area_struct or rbnode or somewhere
      worse.  "mpol=prefer" and "mpol=prefer:Node" are equally toxic.
      
      Recent NUMA enhancements are not to blame: this dates back to 2.6.35,
      when commit e17f74af
      
       "mempolicy: don't call mpol_set_nodemask() when
      no_context" skipped mpol_parse_str()'s call to mpol_set_nodemask(),
      which used to initialize v.preferred_node, or set MPOL_F_LOCAL in flags.
      With slab poisoning, you can then rely on mpol_to_str() to set the bit
      for node 0x6b6b, probably in the next page above the caller's stack.
      
      mpol_parse_str() is only called from shmem_parse_options(): no_context
      is always true, so call it unused for now, and remove !no_context code.
      Set v.nodes or v.preferred_node or MPOL_F_LOCAL as mpol_to_str() might
      expect.  Then mpol_to_str() can ignore its no_context argument also,
      the mpol being appropriately initialized whether contextualized or not.
      Rename its no_context unused too, and let subsequent patch remove them
      (that's not needed for stable backporting, which would involve rejects).
      
      I don't understand why MPOL_LOCAL is described as a pseudo-policy:
      it's a reasonable policy which suffers from a confusing implementation
      in terms of MPOL_PREFERRED with MPOL_F_LOCAL.  I believe this would be
      much more robust if MPOL_LOCAL were recognized in switch statements
      throughout, MPOL_F_LOCAL deleted, and MPOL_PREFERRED use the (possibly
      empty) nodes mask like everyone else, instead of its preferred_node
      variant (I presume an optimization from the days before MPOL_LOCAL).
      But that would take me too long to get right and fully tested.

      epoll: prevent missed events on EPOLL_CTL_MOD · 128dd175
      Eric Wong authored
      EPOLL_CTL_MOD sets the interest mask before calling f_op->poll() to
      ensure events are not missed.  Since the modifications to the interest
      mask are not protected by the same lock as ep_poll_callback, we need to
      ensure the change is visible to other CPUs calling ep_poll_callback.
      
      We also need to ensure f_op->poll() has an up-to-date view of past
      events which occured before we modified the interest mask.  So this
      barrier also pairs with the barrier in wq_has_sleeper().
      
      This should guarantee either ep_poll_callback or f_op->poll() (or both)
      will notice the readiness of a recently-ready/modified item.

      libceph: fix protocol feature mismatch failure path · 0fa6ebc6
      Sage Weil authored
      
      
      We should not set con->state to CLOSED here; that happens in
      ceph_fault() in the caller, where it first asserts that the state
      is not yet CLOSED.  Avoids a BUG when the features don't match.
      
      Since the fail_protocol() has become a trivial wrapper, replace
      calls to it with direct calls to reset_connection().

      libceph: WARN, don't BUG on unexpected connection states · 122070a2
      Alex Elder authored
      
      
      A number of assertions in the ceph messenger are implemented with
      BUG_ON(), killing the system if connection's state doesn't match
      what's expected.  At this point our state model is (evidently) not
      well understood enough for these assertions to trigger a BUG().
      Convert all BUG_ON(con->state...) calls to be WARN_ON(con->state...)
      so we learn about these issues without killing the machine.
      
      We now recognize that a connection fault can occur due to a socket
      closure at any time, regardless of the state of the connection.  So
      there is really nothing we can assert about the state of the
      connection at that point so eliminate that assertion.

      libceph: always reset osds when kicking · e6d50f67
      Alex Elder authored
      
      
      When ceph_osdc_handle_map() is called to process a new osd map,
      kick_requests() is called to ensure all affected requests are
      updated if necessary to reflect changes in the osd map.  This
      happens in two cases:  whenever an incremental map update is
      processed; and when a full map update (or the last one if there is
      more than one) gets processed.
      
      In the former case, the kick_requests() call is followed immediately
      by a call to reset_changed_osds() to ensure any connections to osds
      affected by the map change are reset.  But for full map updates
      this isn't done.
      
      Both cases should be doing this osd reset.
      
      Rather than duplicating the reset_changed_osds() call, move it into
      the end of kick_requests().

      libceph: move linger requests sooner in kick_requests() · ab60b16d
      Alex Elder authored
      
      
      The kick_requests() function is called by ceph_osdc_handle_map()
      when an osd map change has been indicated.  Its purpose is to
      re-queue any request whose target osd is different from what it
      was when it was originally sent.
      
      It is structured as two loops, one for incomplete but registered
      requests, and a second for handling completed linger requests.
      As a special case, in the first loop if a request marked to linger
      has not yet completed, it is moved from the request list to the
      linger list.  This is as a quick and dirty way to have the second
      loop handle sending the request along with all the other linger
      requests.
      
      Because of the way it's done now, however, this quick and dirty
      solution can result in these incomplete linger requests never
      getting re-sent as desired.  The problem lies in the fact that
      the second loop only arranges for a linger request to be sent
      if it appears its target osd has changed.  This is the proper
      handling for *completed* linger requests (it avoids issuing
      the same linger request twice to the same osd).
      
      But although the linger requests added to the list in the first loop
      may have been sent, they have not yet completed, so they need to be
      re-sent regardless of whether their target osd has changed.
      
      The first required fix is we need to avoid calling __map_request()
      on any incomplete linger request.  Otherwise the subsequent
      __map_request() call in the second loop will find the target osd
      has not changed and will therefore not re-send the request.
      
      Second, we need to be sure that a sent but incomplete linger request
      gets re-sent.  If the target osd is the same with the new osd map as
      it was when the request was originally sent, this won't happen.
      This can be fixed through careful handling when we move these
      requests from the request list to the linger list, by unregistering
      the request *before* it is registered as a linger request.  This
      works because a side-effect of unregistering the request is to make
      the request's r_osd pointer be NULL, and *that* will ensure the
      second loop actually re-sends the linger request.
      
      Processing of such a request is done at that point, so continue with
      the next one once it's been moved.
