      nvme-fc: Revert "add module to ops template to allow module references" · 8c5c6605
      James Smart authored
      The original patch was to resolve the lldd being able to be unloaded
      while being used to talk to the boot device of the system. However, the
      end result of the original patch is that any driver unload while a nvme
      controller is live via the lldd is now being prohibited. Given the module
      reference, the module teardown routine can't be called, thus there's no
      way, other than manual actions to terminate the controllers.

      nvme: fix deadlock caused by ANA update wrong locking · 657f1975
      Sagi Grimberg authored
      The deadlock combines 4 flows in parallel:
      - ns scanning (triggered from reconnect)
      - request timeout
      - ANA update (triggered from reconnect)
      - I/O coming into the mpath device
      
      (1) ns scanning triggers disk revalidation -> update disk info ->
          freeze queue -> but blocked, due to (2)
      
      (2) timeout handler reference the g_usage_counter - > but blocks in
          the transport .timeout() handler, due to (3)
      
      (3) the transport timeout handler (indirectly) calls nvme_stop_queue() ->
          which takes the (down_read) namespaces_rwsem - > but blocks, due to (4)
      
      (4) ANA update takes the (down_write) namespaces_rwsem -> calls
          nvme_mpath_set_live() -> which synchronize the ns_head srcu
          (see commit 504db087) -> but blocks, due to (5)
      
      (5) I/O came into nvme_mpath_make_request -> took srcu_read_lock ->
          direct_make_request > blk_queue_enter -> but blocked, due to (1)
      
      ==> the request queue is under freeze -> deadlock.
      
      The fix is making ANA update take a read lock as the namespaces list
      is not manipulated, it is just the ns and ns->head that are being
      updated (which is protected with the ns->head lock).

      nvmet-rdma: fix bonding failover possible NULL deref · a032e4f6
      Sagi Grimberg authored
      RDMA_CM_EVENT_ADDR_CHANGE event occur in the case of bonding failover
      on normal as well as on listening cm_ids. Hence this event will
      immediately trigger a NULL dereference trying to disconnect a queue
      for a cm_id that actually belongs to the port.
      
      To fix this we provide a different handler for the listener cm_ids
      that will defer a work to disable+(re)enable the port which essentially
      destroys and setups another listener cm_id

      nvme-tcp: fix possible crash in recv error flow · 39d06079
      Sagi Grimberg authored
      If the target misbehaves and sends us unexpected payload we
      need to make sure to fail the controller and stop processing
      the input stream. We clear the rd_enabled flag and stop
      the io_work, but we may still requeue it if we still have pending
      sends and then in the next invocation we will process the input
      stream as the check is only in the .data_ready upcall.
      
      To fix this we need to make sure not to self-requeue io_work
      upon a recv flow error.
      
      This fixes the crash:
       nvme nvme2: receive failed:  -22

      nvme-tcp: fix possible crash in write_zeroes processing · 25e5cb78

      We cannot look at blk_rq_payload_bytes without first checking
      that the request has a mappable physical segments first (e.g.
      blk_rq_nr_phys_segments(rq) != 0) and only then to take the
      request payload bytes. This caused us to send a wrong sgl to
      the target or even dereference a non-existing buffer in case
      we actually got to the data send sequence (if it was in-capsule).

      nvme: fix compat address handling in several ioctls · c95b708d
      Nick Bowler authored
      On a 32-bit kernel, the upper bits of userspace addresses passed via
      various ioctls are silently ignored by the nvme driver.
      
      However on a 64-bit kernel running a compat task, these upper bits are
      not ignored and are in fact required to be zero for the ioctls to work.
      
      Unfortunately, this difference matters.  32-bit smartctl submits the
      NVME_IOCTL_ADMIN_CMD ioctl with garbage in these upper bits because it
      seems the pointer value it puts into the nvme_passthru_cmd structure is
      sign extended.  This works fine on 32-bit kernels but fails on a 64-bit
      one because (at least on my setup) the addresses smartctl uses are
      consistently above 2G.  For example:
      
        # smartctl -x /dev/nvme0n1
        smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.5.11] (local build)
        Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org
      
        Read NVMe Identify Controller failed: NVME_IOCTL_ADMIN_CMD: Bad address
      
      Since changing 32-bit kernels to actually check all of the submitted
      address bits now would break existing userspace, this patch fixes the
      compat problem by explicitly zeroing the upper bits in the compat case.
      This enables 32-bit smartctl to work on a 64-bit kernel.

      Pull x86 timer updates from Thomas Gleixner:
       "A series of commits to make the MSR derived CPU and TSC frequency more
        accurate.
      
        It turned out that the frequency tables which have been taken from the
        SDM are inaccurate because the SDM provides truncated and rounded
        values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...).
      
        This causes time drift in the range of ~1 second per hour (20-30
        seconds per day). On some of these SoCs it's not possible to
        recalibrate the TSC because there is no reference (PIT, HPET)
        available.
      
        With some reverse engineering it was established that the possible
        frequencies are derived from the base clock with fixed multiplier /
        divider pairs.
      
        For the CPU models which have a known crystal frequency the kernel now
        uses multiplier / divider pairs which bring the frequencies closer to
        reality and fix the observed time drift issues"

      Pull irq updates from Thomas Gleixner:
       "Updates for the interrupt subsystem:
      
        Treewide:
      
          - Cleanup of setup_irq() which is not longer required because the
            memory allocator is available early.
      
            Most cleanup changes come through the various maintainer trees, so
            the final removal of setup_irq() is postponed towards the end of
            the merge window.
      
        Core:
      
          - Protection against unsafe invocation of interrupt handlers and
            unsafe interrupt injection including a fixup of the offending
            PCI/AER error injection mechanism.
      
            Invoking interrupt handlers from arbitrary contexts, i.e. outside
            of an actual interrupt, can cause inconsistent state on the
            fragile x86 interrupt affinity changing hardware trainwreck.
      
        Drivers:
      
          - Second wave of support for the new ARM GICv4.1
      
          - Multi-instance support for Xilinx and PLIC interrupt controllers
      
          - CPU-Hotplug support for PLIC
      
          - The obligatory new driver for X1000 TCU

      staging/octeon: fix up merge error · 673b41e0
      Randy Dunlap authored
      There's a semantic conflict in the Octeon staging network driver, which
      used the skb_reset_tc() function to reset skb state when re-using an
      skb.  But that inline helper function was removed in mainline by commit
      2c64605b ("net: Fix CONFIG_NET_CLS_ACT=n and
      CONFIG_NFT_FWD_NETDEV={y, m} build").
      
      Fix it by using skb_reset_redirect() instead.  Also move it out of the
      
      This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is
      enabled, which in turn only happens if you don't have CONFIG_NETFILTER
      configured.  Which was how this wasn't caught by the usual allmodconfig
      builds.

      Pull scheduler updates from Ingo Molnar:
       "The main changes in this cycle are:
      
         - Various NUMA scheduling updates: harmonize the load-balancer and
           NUMA placement logic to not work against each other. The intended
           result is better locality, better utilization and fewer migrations.
      
         - Introduce Thermal Pressure tracking and optimizations, to improve
           task placement on thermally overloaded systems.
      
         - Implement frequency invariant scheduler accounting on (some) x86
           CPUs. This is done by observing and sampling the 'recent' CPU
           frequency average at ~tick boundaries. The CPU provides this data
           via the APERF/MPERF MSRs. This hopefully makes our capacity
           estimates more precise and keeps tasks on the same CPU better even
           if it might seem overloaded at a lower momentary frequency. (As
           usual, turbo mode is a complication that we resolve by observing
           the maximum frequency and renormalizing to it.)
      
         - Add asymmetric CPU capacity wakeup scan to improve capacity
           utilization on asymmetric topologies. (big.LITTLE systems)
      
         - PSI fixes and optimizations.
      
         - RT scheduling capacity awareness fixes & improvements.
      
         - Optimize the CONFIG_RT_GROUP_SCHED constraints code.

      Pull EFI updates from Ingo Molnar:
       "The EFI changes in this cycle are much larger than usual, for two
        (positive) reasons:
      
         - The GRUB project is showing signs of life again, resulting in the
           introduction of the generic Linux/UEFI boot protocol, instead of
           x86 specific hacks which are increasingly difficult to maintain.
           There's hope that all future extensions will now go through that
           boot protocol.
      
         - Preparatory work for RISC-V EFI support.
      
        The main changes are:
      
         - Boot time GDT handling changes
      
         - Simplify handling of EFI properties table on arm64
      
         - Generic EFI stub cleanups, to improve command line handling, file
           I/O, memory allocation, etc.
      
         - Introduce a generic initrd loading method based on calling back
           into the firmware, instead of relying on the x86 EFI handover
           protocol or device tree.
      
         - Introduce a mixed mode boot method that does not rely on the x86
           EFI handover protocol either, and could potentially be adopted by
           other architectures (if another one ever surfaces where one
           execution mode is a superset of another)
      
         - Clean up the contents of 'struct efi', and move out everything that
           doesn't need to be stored there.
      
         - Incorporate support for UEFI spec v2.8A changes that permit
           firmware implementations to return EFI_UNSUPPORTED from UEFI
           runtime services at OS runtime, and expose a mask of which ones are
           supported or unsupported via a configuration table.
      
         - Partial fix for the lack of by-VA cache maintenance in the
           decompressor on 32-bit ARM.
      
         - Changes to load device firmware from EFI boot service memory
           regions
      
         - Various documentation updates and minor code cleanups and fixes"

      Pull objtool updates from Ingo Molnar:
       "The biggest changes in this cycle were the vmlinux.o optimizations by
         Peter Zijlstra, which are preparatory and optimization work to run
         objtool against the much richer vmlinux.o object file, to perform
         new, whole-program section based logic. That work exposed a handful
         of problems with the existing code, which fixes and optimizations are
         merged here. The complete 'vmlinux.o and noinstr' work is still work
         in progress, targeted for v5.8.
      
        There's also assorted fixes and enhancements from Josh Poimboeuf.
      
        In particular I'd like to draw attention to commit 644592d3,
        which turns fatal objtool errors into failed kernel builds. This
        behavior is IMO now justified on multiple grounds (it's easy currently
        to not notice an essentially corrupted kernel build), and the commit
        has been in -next testing for several weeks, but there could still be
        build failures with old or weird toolchains. Should that be widespread
        or high profile enough then I'd suggest a quick revert, to not hold up
        the merge window"

       "These clean up and rework the PM QoS API, address a suspend-to-idle
        wakeup regression on some ACPI-based platforms, clean up and extend a
        few cpuidle drivers, update multiple cpufreq drivers and cpufreq
        documentation, and fix a number of issues in devfreq and several other
        things all over.
      
        Specifics:
      
         - Clean up and rework the PM QoS API to simplify the code and reduce
           the size of it (Rafael Wysocki).
      
         - Fix a suspend-to-idle wakeup regression on Dell XPS13 9370 and
           similar platforms where the USB plug/unplug events are handled by

           Ulf Hansson).
      
         - Extend the haltpoll cpuidle driver so that it can be forced to run
           on some systems where it refused to load (Maciej Szmigiero).
      
         - Convert several cpufreq documents to the .rst format and move the
           legacy driver documentation into one common file (Mauro Carvalho
           Chehab, Rafael Wysocki).
      
         - Update several cpufreq drivers:

              * Get rid of doc warnings and fix a typo (Christophe JAILLET).
      
         - Use built-in RCU list checking in some places in the PM core to
           avoid false-positive RCU usage warnings (Madhuparna Bhowmik).
      
         - Add explicit READ_ONCE()/WRITE_ONCE() annotations to low-level PM
           QoS routines (Qian Cai).

           a corner case (Neeraj Upadhyay).
      
         - Clean up the handling of hibernate compat ioctls and fix the
           related documentation (Eric Biggers).

           arrays instead of zero-length arrays (Gustavo Silva).
      
         - Fix list format in a PM QoS document (Randy Dunlap).

        the SPI tree.
      
        This has made a mess which I only just noticed while preparing this
        and I can't see a sensible way to unpick things due to other

        the exfat code (which is coming in again through the vfs tree in a

        But some code does come back, with the octeon drivers being found to
        actually be used in the wild, so those deletions are now reverted.
