      RDMA/iw_cxgb4: initiate CLOSE when entering TERM · d219face
      Krishnamraju Eraparaju authored
      As per draft-hilland-iwarp-verbs-v1.0, sec 6.2.3, always initiate a CLOSE
      when entering into TERM state.
      
      In c4iw_modify_qp(), disconnect operation should only be performed when
      the modify_qp call is invoked from ib_core. And all other internal
      modify_qp calls(invoked within iw_cxgb4) that needs 'disconnect' should
      call c4iw_ep_disconnect() explicitly after modify_qp. Otherwise, deadlocks
      like below can occur:

      IB/mlx5: Return failure when rts2rts_qp_counters_set_id is not supported · 10189e8e
      Mark Zhang authored
      When binding a QP with a counter and the QP state is not RESET, return
      failure if the rts2rts_qp_counters_set_id is not supported by the
      device.
      
      This is to prevent cases like manual bind for Connect-IB devices from
      returning success when the feature is not supported.

      RDMA/core: Fix invalid memory access in spec_filter_size · a72f4ac1
      Avihai Horon authored
      Add a check that the size specified in the flow spec header doesn't cause

      IB/rdmavt: Reset all QPs when the device is shut down · f92e4871
      Kaike Wan authored
      When the hfi1 device is shut down during a system reboot, it is possible
      that some QPs might have not not freed by ULPs. More requests could be
      post sent and a lingering timer could be triggered to schedule more packet
      sends, leading to a crash:

      The solution is to reset the QPs before the device resources are freed.
      This reset will change the QP state to prevent post sends and delete
      timers to prevent callbacks.

      The panic is the result of slab entries being freed during the destruction
      of the pq slab.
      
      The code attempts to quiesce the pq, but looking for n_req == 0 doesn't
      account for new requests.
      
      Fix the issue by using SRCU to get a pq pointer and adjust the pq free
      logic to NULL the fd pq pointer prior to the quiesce.

      IB/hfi1: Acquire lock to release TID entries when user file is closed · a70ed0f2
      Kaike Wan authored
      Each user context is allocated a certain number of RcvArray (TID)
      entries and these entries are managed through TID groups. These groups
      are put into one of three lists in each user context: tid_group_list,
      tid_used_list, and tid_full_list, depending on the number of used TID
      entries within each group. When TID packets are expected, one or more
      TID groups will be allocated. After the packets are received, the TID
      groups will be freed. Since multiple user threads may access the TID
      groups simultaneously, a mutex exp_mutex is used to synchronize the
      access. However, when the user file is closed, it tries to release
      all TID groups without acquiring the mutex first, which risks a race
      condition with another thread that may be releasing its TID groups,
      leading to data corruption.
      
      This patch addresses the issue by acquiring the mutex first before
      releasing the TID groups when the file is closed.

      Linus Torvalds authored
      Pull new zonefs file system from Damien Le Moal:
       "Zonefs is a very simple file system exposing each zone of a zoned
        block device as a file.
      
        Unlike a regular file system with native zoned block device support
        (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
        sequential write constraint of zoned block devices to the user. As a
        result, zonefs is not a POSIX compliant file system. Its goal is to
        simplify the implementation of zoned block devices support in
        applications by replacing raw block device file accesses with a richer
        file based API, avoiding relying on direct block device file ioctls
        which may be more obscure to developers.
      
        One example of this approach is the implementation of LSM
        (log-structured merge) tree structures (such as used in RocksDB and
        LevelDB) on zoned block devices by allowing SSTables to be stored in a
        zone file similarly to a regular file system rather than as a range of
        sectors of a zoned device. The introduction of the higher level
        construct "one file is one zone" can help reducing the amount of
        changes needed in the application while at the same time allowing the
        use of zoned block devices with various programming languages other
        than C.
      
        Zonefs IO management implementation uses the new iomap generic code.
        Zonefs has been successfully tested using a functional test suite
        (available with zonefs userland format tool on github) and a prototype
        implementation of LevelDB on top of zonefs"

      Pull x86 fixes from Thomas Gleixner:
       "A set of fixes for X86:
      
         - Ensure that the PIT is set up when the local APIC is disable or
           configured in legacy mode. This is caused by an ordering issue
           introduced in the recent changes which skip PIT initialization when
           the TSC and APIC frequencies are already known.
      
         - Handle malformed SRAT tables during early ACPI parsing which caused
           an infinite loop anda boot hang.
      
         - Fix a long standing race in the affinity setting code which affects
           PCI devices with non-maskable MSI interrupts. The problem is caused
           by the non-atomic writes of the MSI address (destination APIC id)
           and data (vector) fields which the device uses to construct the MSI
           message. The non-atomic writes are mandated by PCI.
      
           If both fields change and the device raises an interrupt after
           writing address and before writing data, then the MSI block
           constructs a inconsistent message which causes interrupts to be
           lost and subsequent malfunction of the device.
      
           The fix is to redirect the interrupt to the new vector on the
           current CPU first and then switch it over to the new target CPU.
           This allows to observe an eventually raised interrupt in the
           transitional stage (old CPU, new vector) to be observed in the APIC
           IRR and retriggered on the new target CPU and the new vector.
      
           The potential spurious interrupts caused by this are harmless and

      fs: Add VirtualBox guest shared folder (vboxsf) support · 0fd16957
      Hans de Goede authored
      VirtualBox hosts can share folders with guests, this commit adds a
      VFS driver implementing the Linux-guest side of this, allowing folders
      exported by the host to be mounted under Linux.
      
      This driver depends on the guest <-> host IPC functions exported by
      the vboxguest driver.

      Fix up remaining devm_ioremap_nocache() in SGI IOC3 8250 UART driver · b0ef7cda
      Linus Torvalds authored
      This is a merge error on my part - the driver was merged into mainline
      by commit c5951e7c ("Merge tag 'mips_5.6' of git://../mips/linux")
      over a week ago, but nobody apparently noticed that it didn't actually
      build due to still having a reference to the devm_ioremap_nocache()
      function, removed a few days earlier through commit 6a1000bd ("Merge
      tag 'ioremap-5.6' of git://../ioremap").
      
      Apparently this didn't get any build testing anywhere.  Not perhaps all
      that surprising: it's restricted to 64-bit MIPS only, and only with the
      new SGI_MFD_IOC3 support enabled.
      
      I only noticed because the ioremap conflicts in the ARM SoC driver
      update made me check there weren't any others hiding, and I found this
      one.

      Pull vfs file system parameter updates from Al Viro:
       "Saner fs_parser.c guts and data structures. The system-wide registry
        of syntax types (string/enum/int32/oct32/.../etc.) is gone and so is
        the horror switch() in fs_parse() that would have to grow another case
        every time something got added to that system-wide registry.
      
        New syntax types can be added by filesystems easily now, and their
        namespace is that of functions - not of system-wide enum members. IOW,
        they can be shared or kept private and if some turn out to be widely
        useful, we can make them common library helpers, etc., without having
        to do anything whatsoever to fs_parse() itself.
      
        And we already get that kind of requests - the thing that finally
        pushed me into doing that was "oh, and let's add one for timeouts -
        things like 15s or 2h". If some filesystem really wants that, let them
        do it. Without somebody having to play gatekeeper for the variants
        blessed by direct support in fs_parse(), TYVM.
      
        Quite a bit of boilerplate is gone. And IMO the data structures make a
        lot more sense now. -200LoC, while we are at it"
