      nvmet-rdma: fix possible bogus dereference under heavy load · 8407879c
      Sagi Grimberg authored
      
      
      Currently we always repost the recv buffer before we send a response
      capsule back to the host. Since ordering is not guaranteed for send
      and recv completions, it is posible that we will receive a new request
      from the host before we got a send completion for the response capsule.
      
      Today, we pre-allocate 2x rsps the length of the queue, but in reality,
      under heavy load there is nothing that is really preventing the gap to
      expand until we exhaust all our rsps.
      
      To fix this, if we don't have any pre-allocated rsps left, we dynamically
      allocate a rsp and make sure to free it when we are done. If under memory
      pressure we fail to allocate a rsp, we silently drop the command and
      wait for the host to retry.

      blkcg: use tryget logic when associating a blkg with a bio · 31118850
      Dennis Zhou (Facebook) authored
      There is a very small change a bio gets caught up in a really
      unfortunate race between a task migration, cgroup exiting, and itself
      trying to associate with a blkg. This is due to css offlining being
      performed after the css->refcnt is killed which triggers removal of
      blkgs that reach their blkg->refcnt of 0.
      
      To avoid this, association with a blkg should use tryget and fallback to
      using the root_blkg.

      blkcg: delay blkg destruction until after writeback has finished · 59b57717
      Dennis Zhou (Facebook) authored
      Currently, blkcg destruction relies on a sequence of events:
        1. Destruction starts. blkcg_css_offline() is called and blkgs
           release their reference to the blkcg. This immediately destroys
           the cgwbs (writeback).
        2. With blkgs giving up their reference, the blkcg ref count should
           become zero and eventually call blkcg_css_free() which finally
           frees the blkcg.
      
      Jiufei Xue reported that there is a race between blkcg_bio_issue_check()
      and cgroup_rmdir(). To remedy this, blkg destruction becomes contingent
      on the completion of all writeback associated with the blkcg. A count of
      the number of cgwbs is maintained and once that goes to zero, blkg
      destruction can follow. This should prevent premature blkg destruction
      related to writeback.
      
      The new process for blkcg cleanup is as follows:
        1. Destruction starts. blkcg_css_offline() is called which offlines
           writeback. Blkg destruction is delayed on the cgwb_refcnt count to
           avoid punting potentially large amounts of outstanding writeback
           to root while maintaining any ongoing policies. Here, the base
           cgwb_refcnt is put back.
        2. When the cgwb_refcnt becomes zero, blkcg_destroy_blkgs() is called
           and handles destruction of blkgs. This is where the css reference
           held by each blkg is released.
        3. Once the blkcg ref count goes to zero, blkcg_css_free() is called.
           This finally frees the blkg.
      
      It seems in the past blk-throttle didn't do the most understandable
      things with taking data from a blkg while associating with current. So,
      the simplification and unification of what blk-throttle is doing caused
      this.

      Revert "blk-throttle: fix race between blkcg_bio_issue_check() and cgroup_rmdir()" · 6b065462
      Dennis Zhou (Facebook) authored
      This reverts commit 4c699480.
      
      Destroying blkgs is tricky because of the nature of the relationship. A
      blkg should go away when either a blkcg or a request_queue goes away.
      However, blkg's pin the blkcg to ensure they remain valid. To break this
      cycle, when a blkcg is offlined, blkgs put back their css ref. This
      eventually lets css_free() get called which frees the blkcg.
      
      The above commit (4c699480) breaks this order of events by trying to
      destroy blkgs in css_free(). As the blkgs still hold references to the
      blkcg, css_free() is never called.
      
      The race between blkcg_bio_issue_check() and cgroup_rmdir() will be
      addressed in the following patch by delaying destruction of a blkg until
      all writeback associated with the blkcg has been finished.

      nvme-fcloop: Fix dropped LS's to removed target port · afd299ca
      James Smart authored
      
      
      When a targetport is removed from the config, fcloop will avoid calling
      the LS done() routine thinking the targetport is gone. This leaves the
      initiator reset/reconnect hanging as it waits for a status on the
      Create_Association LS for the reconnect.
      
      Change the filter in the LS callback path. If tport null (set when
      failed validation before "sending to remote port"), be sure to call
      done. This was the main bug. But, continue the logic that only calls
      done if tport was set but there is no remoteport (e.g. case where
      remoteport has been removed, thus host doesn't expect a completion).

      nvme-pci: add a memory barrier to nvme_dbbuf_update_and_check_event · f1ed3df2
      Michal Wnukowski authored
      In many architectures loads may be reordered with older stores to
      different locations.  In the nvme driver the following two operations
      could be reordered:
      
       - Write shadow doorbell (dbbuf_db) into memory.
       - Read EventIdx (dbbuf_ei) from memory.
      
      This can result in a potential race condition between driver and VM host
      processing requests (if given virtual NVMe controller has a support for
      shadow doorbell).  If that occurs, then the NVMe controller may decide to
      wait for MMIO doorbell from guest operating system, and guest driver may
      decide not to issue MMIO doorbell on any of subsequent commands.
      
      This issue is purely timing-dependent one, so there is no easy way to
      reproduce it. Currently the easiest known approach is to run "Oracle IO
      Numbers" (orion) that is shipped with Oracle DB:
      
      orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \
      	concat -write 40 -duration 120 -matrix row -testname nvme_test
      
      Where nvme_test is a .lun file that contains a list of NVMe block
      devices to run test against. Limiting number of vCPUs assigned to given
      VM instance seems to increase chances for this bug to occur. On test
      environment with VM that got 4 NVMe drives and 1 vCPU assigned the
      virtual NVMe controller hang could be observed within 10-20 minutes.
      That correspond to about 400-500k IO operations processed (or about
      100GB of IO read/writes).
      
      Orion tool was used as a validation and set to run in a loop for 36
      hours (equivalent of pushing 550M IO operations). No issues were
      observed. That suggest that the patch fixes the issue.

      block: bsg: move atomic_t ref_count variable to refcount API · db193954
      John Pittman authored
      
      
      Currently, variable ref_count within the bsg_device struct is of
      type atomic_t.  For variables being used as reference counters,
      the refcount API should be used instead of atomic.  The newer
      refcount API works to prevent counter overflows and use-after-free
      bugs.  So, move this varable from the atomic API to refcount,
      potentially avoiding the issues mentioned.

      Pull s390 updates from Martin Schwidefsky:
      
       - A couple of patches for the zcrypt driver:
           + Add two masks to determine which AP cards and queues are host
             devices, this will be useful for KVM AP device passthrough
           + Add-on patch to improve the parsing of the new apmask and aqmask
           + Some code beautification
      
       - Second try to reenable the GCC plugins, the first patch set had a
         patch to do this but the merge somehow missed this
      
       - Remove the s390 specific GCC version check and use the generic one
      
       - Three patches for kdump, two bug fixes and one cleanup
      
       - Three patches for the PCI layer, one bug fix and two cleanups
      
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
        s390: remove gcc version check (4.3 or newer)

       "This is a set of four fairly obvious bug fixes:
      
         - a switch from d_find_alias to d_find_any_alias because the xattr

         - two mutex vs copy_to_user fixes from Jann Horn
      
         - a fix to use a sanitized size not the size userspace passed in from
           Christian Brauner"
