       - Add the mask_port_map parameter to the ahci driver. This is a
         follow-up to the recent snafu with the ASMedia controller and its
         virtual port hidding port-multiplier devices. As ASMedia confirmed
         that there is no way to determine if these slow-to-probe virtual
         ports are actually representing the ports of a port-multiplier
         devices, this new parameter allow masking ports to significantly
         speed up probing during system boot, resulting in shorter boot times.
      
       - A fix for an incorrect handling of a port unlock in
         ata_scsi_dev_rescan().
      
       - Allow command duration limits to be detected for ACS-4 devices are
         there are such devices out in the field.

      ata: libata-core: Allow command duration limits detection for ACS-4 drives · c0297e7d
      Igor Pylypiv authored
      Even though the command duration limits (CDL) feature was first added
      in ACS-5 (major version 12), there are some ACS-4 (major version 11)
      drives that implement CDL as well.
      
      IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages
      are mandatory in the ACS-4 standard so it should be safe to read these
      log pages on older drives implementing the ACS-4 standard.

      ata: libata-scsi: Fix ata_scsi_dev_rescan() error path · 79336504
      Damien Le Moal authored
      Commit 0c76106c ("scsi: sd: Fix TCG OPAL unlock on system resume")
      incorrectly handles failures of scsi_resume_device() in
      ata_scsi_dev_rescan(), leading to a double call to
      spin_unlock_irqrestore() to unlock a device port. Fix this by redefining
      the goto labels used in case of errors and only unlock the port
      scsi_scan_mutex when scsi_resume_device() fails.
      
      Bug found with the Smatch static checker warning:
      
      	drivers/ata/libata-scsi.c:4774 ata_scsi_dev_rescan()
      	error: double unlocked 'ap->lock' (orig line 4757)

      Kconfig: add some hidden tabs on purpose · d5cf50da
      Linus Torvalds authored
      Commit d96c3600 ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig
      entry") removed a hidden tab because it apparently showed breakage in
      some third-party kernel config parsing tool.
      
      It wasn't clear what tool it was, but let's make sure it gets fixed.
      Because if you can't parse tabs as whitespace, you should not be parsing
      the kernel Kconfig files.
      
      In fact, let's make such breakage more obvious than some esoteric ftrace
      record size option.  If you can't parse tabs, you can't have page sizes.
      
      Yes, tab-vs-space confusion is sadly a traditional Unix thing, and
      'make' is famous for being broken in this regard.  But no, that does not
      mean that it's ok.
      
      I'd add more random tabs to our Kconfig files, but I don't want to make
      things uglier than necessary.  But it *might* bbe necessary if it turns
      out we see more of this kind of silly tooling.

      Pull tracing fixes from Steven Rostedt:
      
       - Fix the buffer_percent accounting as it is dependent on three
         variables:
      
           1) pages_read - number of subbuffers read
           2) pages_lost - number of subbuffers lost due to overwrite
           3) pages_touched - number of pages that a writer entered
      
         These three counters only increment, and to know how many active
         pages there are on the buffer at any given time, the pages_read and
         pages_lost are subtracted from pages_touched.
      
         But the pages touched was incremented whenever any writer went to the
         next subbuffer even if it wasn't the only one, so it was incremented
         more than it should be causing the counter for how many subbuffers
         currently have content incorrect, which caused the buffer_percent
         that holds waiters until the ring buffer is filled to a given
         percentage to wake up early.

      block: fix that blk_time_get_ns() doesn't update time after schedule · 3ec48489
      Yu Kuai authored
      While monitoring the throttle time of IO from iocost, it's found that
      such time is always zero after the io_schedule() from ioc_rqos_throttle,
      for example, with the following debug patch:
      
      +       printk("%s-%d: %s enter %llu\n", current->comm, current->pid, __func__, blk_time_get_ns());
              while (true) {
                      set_current_state(TASK_UNINTERRUPTIBLE);
                      if (wait.committed)
                              break;
                      io_schedule();
              }
      +       printk("%s-%d: %s exit  %llu\n", current->comm, current->pid, __func__, blk_time_get_ns());
      
      It can be observerd that blk_time_get_ns() always return the same time:
      
      [ 1068.096579] fio-1268: ioc_rqos_throttle enter 1067901962288
      [ 1068.272587] fio-1268: ioc_rqos_throttle exit  1067901962288
      [ 1068.274389] fio-1268: ioc_rqos_throttle enter 1067901962288
      [ 1068.472690] fio-1268: ioc_rqos_throttle exit  1067901962288
      [ 1068.474485] fio-1268: ioc_rqos_throttle enter 1067901962288
      [ 1068.672656] fio-1268: ioc_rqos_throttle exit  1067901962288
      [ 1068.674451] fio-1268: ioc_rqos_throttle enter 1067901962288
      [ 1068.872655] fio-1268: ioc_rqos_throttle exit  1067901962288
      
      And I think the root cause is that 'PF_BLOCK_TS' is always cleared
      by blk_flush_plug() before scheduel(), hence blk_plug_invalidate_ts()
      will never be called:
      
      blk_time_get_ns
       plug->cur_ktime = ktime_get_ns();
       current->flags |= PF_BLOCK_TS;
      
      io_schedule:
       io_schedule_prepare
        blk_flush_plug
         __blk_flush_plug
          /* the flag is cleared, while time is not */
          current->flags &= ~PF_BLOCK_TS;
       schedule
       sched_update_worker
        /* the flag is not set, hence plug->cur_ktime is not cleared */
        if (tsk->flags & PF_BLOCK_TS)
         blk_plug_invalidate_ts()
      
      blk_time_get_ns
       /* got the time stashed before schedule */
       return plug->cur_ktime;
      
      Fix the problem by clearing cached time in __blk_flush_plug().
      
      Fixes: 06b23f92 ("block: update cached timestamp post schedule/preemption")

      iommu/vt-d: Fix WARN_ON in iommu probe path · 89436f4f
      Lu Baolu authored
      Commit 1a75cc71 ("iommu/vt-d: Use rbtree to track iommu probed
      devices") adds all devices probed by the iommu driver in a rbtree
      indexed by the source ID of each device. It assumes that each device
      has a unique source ID. This assumption is incorrect and the VT-d
      spec doesn't state this requirement either.
      
      The reason for using a rbtree to track devices is to look up the device
      with PCI bus and devfunc in the paths of handling ATS invalidation time
      out error and the PRI I/O page faults. Both are PCI ATS feature related.
      
      Only track the devices that have PCI ATS capabilities in the rbtree to
      avoid unnecessary WARN_ON in the iommu probe path. Otherwise, on some
      platforms below kernel splat will be displayed and the iommu probe results
      in failure.

      iommu/amd: Do not enable SNP when V2 page table is enabled · b650b38b
      Vasant Hegde authored
      DTE[Mode]=0 is not supported when SNP is enabled in the host. That means
      to support SNP, IOMMU must be configured with V1 page table (See IOMMU
      spec [1] for the details). If user passes kernel command line to configure
      IOMMU domains with v2 page table (amd_iommu=pgtbl_v2) then disable SNP
      as the user asked by not forcing the page table to v1.

      variables that determine the amount of data that is in the ring buffer:
      
       1) pages_read - incremented whenever a new sub-buffer is consumed
       2) pages_lost - incremented every time a writer overwrites a sub-buffer
       3) pages_touched - incremented when a write goes to a new sub-buffer
      
      The percentage is the calculation of:
      
        (pages_touched - (pages_lost + pages_read)) / nr_pages
      
      Basically, the amount of data is the total number of sub-bufs that have been
      touched, minus the number of sub-bufs lost and sub-bufs consumed. This is
      divided by the total count to give the buffer percentage. When the
      percentage is greater than the value in the "buffer_percent" file, it
      wakes up splice readers waiting for that amount.
      
      It was observed that over time, the amount read from the splice was
      constantly decreasing the longer the trace was running. That is, if one
      asked for 60%, it would read over 60% when it first starts tracing, but
      then it would be woken up at under 60% and would slowly decrease the
      amount of data read after being woken up, where the amount becomes much
      less than the buffer percent.
      
      This was due to an accounting of the pages_touched incrementation. This
      value is incremented whenever a writer transfers to a new sub-buffer. But
      the place where it was incremented was incorrect. If a writer overflowed
      the current sub-buffer it would go to the next one. If it gets preempted
      by an interrupt at that time, and the interrupt performs a trace, it too
      will end up going to the next sub-buffer. But only one should increment
      the counter. Unfortunately, that was not the case.
      
      Change the cmpxchg() that does the real switch of the tail-page into a
      try_cmpxchg(), and on success, perform the increment of pages_touched. This
      will only increment the counter once for when the writer moves to a new
      sub-buffer, and not when there's a race and is incremented for when a
      writer and its preempting writer both move to the same new sub-buffer.

      smb3: fix broken reconnect when password changing on the server by allowing password rotation · 35f83426
      Steve French authored
      There are various use cases that are becoming more common in which password
      changes are scheduled on a server(s) periodically but the clients connected
      to this server need to stay connected (even in the face of brief network
      reconnects) due to mounts which can not be easily unmounted and mounted at
      will, and servers that do password rotation do not always have the ability
      to tell the clients exactly when to the new password will be effective,
      so add support for an alt password ("password2=") on mount (and also
      remount) so that we can anticipate the upcoming change to the server
      without risking breaking existing mounts.
      
      An alternative would have been to use the kernel keyring for this but the
      processes doing the reconnect do not have access to the keyring but do
      have access to the ses structure.
