24717cfbbb The one new feature this time, from Anna Schumaker, is READ_PLUS, which
has the same arguments as READ but allows the server to return an array
 of data and hole extents.
 
 Otherwise it's a lot of cleanup and bugfixes.

eae503f7eb exfat: remove useless check in exfat_move_file()
In exfat_move_file(), the identity of source and target directory has been
checked by the caller.
Also, it gets stream.start_clu from file dir-entry, which is an invalid
determination.

Remove 'rwoffset' in exfat_inode_info and replace it with the parameter of
exfat_readdir().
Since rwoffset is referenced only by exfat_readdir(), it is not necessary
a exfat_inode_info's member.
Also, change cpos to point to the next of entry-set, and return the index
of dir-entry via dir_entry->entry.

NFS_FS=y as dependency of CONFIG_NFSD_V4_2_INTER_SSC still have
build errors and some configs with NFSD=m to get NFS4ERR_STALE
error when doing inter server copy.

Added ops table in nfs_common for knfsd to access NFS client modules.

d48c812474 SUNRPC: fix copying of multiple pages in gss_read_proxy_verf()
When the passed token is longer than 4032 bytes, the remaining part
of the token must be copied from the rqstp->rq_arg.pages. But the
copy must make sure it happens in a consecutive way.

With the existing code, the first memcpy copies 'length' bytes from
argv->iobase, but since the header is in front, this never fills the
whole first page of in_token->pages.

The mecpy in the loop copies the following bytes, but starts writing at
the next page of in_token->pages.  This leaves the last bytes of page 0
unwritten.

Symptoms were that users with many groups were not able to access NFS
exports, when using Active Directory as the KDC.

27a1e8a0f7 sunrpc: raise kernel RPC channel buffer size
Its possible that using AUTH_SYS and mountd manage-gids option a
user may hit the 8k RPC channel buffer limit. This have been observed
on field, causing unanswered RPCs on clients after mountd fails to
write on channel :

rpc.mountd[11231]: auth_unix_gid: error writing reply

Userland nfs-utils uses a buffer size of 32k (RPC_CHAN_BUF_SIZE), so
lets match those two.

5f7f77400a xen/events: block rogue events for some time
In order to avoid high dom0 load due to rogue guests sending events at
high frequency, block those events in case there was no action needed
in dom0 to handle the events.

This is done by adding a per-event counter, which set to zero in case
an EOI without the XEN_EOI_FLAG_SPURIOUS is received from a backend
driver, and incremented when this flag has been set. In case the
counter is 2 or higher delay the EOI by 1 << (cnt - 2) jiffies, but
not more than 1 second.

In order not to waste memory shorten the per-event refcnt to two bytes
(it should normally never exceed a value of 2). Add an overflow check
to evtchn_get() to make sure the 2 bytes really won't overflow.

This is part of XSA-332.

e99502f762 xen/events: defer eoi in case of excessive number of events
In case rogue guests are sending events at high frequency it might
happen that xen_evtchn_do_upcall() won't stop processing events in
dom0. As this is done in irq handling a crash might be the result.

In order to avoid that, delay further inter-domain events after some
time in xen_evtchn_do_upcall() by forcing eoi processing into a
worker on the same cpu, thus inhibiting new events coming in.

The time after which eoi processing is to be delayed is configurable
via a new module parameter "event_loop_timeout" which specifies the
maximum event loop time in jiffies (default: 2, the value was chosen
after some tests showing that a value of 2 was the lowest with an
only slight drop of dom0 network throughput while multiple guests
performed an event storm).

How long eoi processing will be delayed can be specified via another
parameter "event_eoi_delay" (again in jiffies, default 10, again the
value was chosen after testing with different delay values).

c2711441bc xen/pciback: use lateeoi irq binding
In order to reduce the chance for the system becoming unresponsive due
to event storms triggered by a misbehaving pcifront use the lateeoi irq
binding for pciback and unmask the event channel only just before
leaving the event handling function.

Restructure the handling to support that scheme. Basically an event can
come in for two reasons: either a normal request for a pciback action,
which is handled in a worker, or in case the guest has finished an AER
request which was requested by pciback.

When an AER request is issued to the guest and a normal pciback action
is currently active issue an EOI early in order to be able to receive
another event when the AER request has been finished by the guest.

Let the worker processing the normal requests run until no further
request is pending, instead of starting a new worker ion that case.
Issue the EOI only just before leaving the worker.

This scheme allows to drop calling the generic function
xen_pcibk_test_and_schedule_op() after processing of any request as
the handling of both request types is now separated more cleanly.

In order to reduce the chance for the system becoming unresponsive due

irq binding for scsiback and unmask the event channel only just before
leaving the event handling function.

In case of a ring protocol error don't issue an EOI in order to avoid
the possibility to use that for producing an event storm. This at once
will result in no further call of scsiback_irq_fn(), so the ring_error

54c9de8989 xen/events: add a new "late EOI" evtchn framework
In order to avoid tight event channel related IRQ loops add a new
framework of "late EOI" handling: the IRQ the event channel is bound
to will be masked until the event has been handled and the related
driver is capable to handle another event. The driver is responsible
for unmasking the event channel via the new function xen_irq_lateeoi().

This is similar to binding an event channel to a threaded IRQ, but
without having to structure the driver accordingly.

In order to support a future special handling in case a rogue guest
is sending lots of unsolicited events, add a flag to xen_irq_lateeoi()
which can be set by the caller to indicate the event was a spurious
one.

4d3fe31bd9 xen/events: add a proper barrier to 2-level uevent unmasking
A follow-up patch will require certain write to happen before an event
channel is unmasked.

While the memory barrier is not strictly necessary for all the callers,
the main one will need it. In order to avoid an extra memory barrier
when using fifo event channels, mandate evtchn_unmask() to provide
write ordering.

The 2-level event handling unmask operation is missing an appropriate
barrier, so add it. Fifo event channels are fine in this regard due to
using sync_cmpxchg().

073d0552ea xen/events: avoid removing an event channel while handling it
Today it can happen that an event channel is being removed from the
system while the event handling loop is active. This can lead to a
race resulting in crashes or WARN() splats when trying to access the
irq_info structure related to the event channel.

Fix this problem by using a rwlock taken as reader in the event
handling loop and as writer when deallocating the irq_info structure.

As the observed problem was a NULL dereference in evtchn_from_irq()
make this function more robust against races by testing the irq_info
pointer to be not NULL before dereferencing it.

And finally make all accesses to evtchn_to_irq[row][col] atomic ones
in order to avoid seeing partial updates of an array element in irq
handling. Note that irq handling can be entered only for event channels
which have been valid before, so any not populated row isn't a problem
in this regard, as rows are only ever added and never removed.

This is XSA-331.

 This contains a merge from the EFI tree that was necessary as some of the EFI
 support landed over there.  It's my first time doing something like this,
 
 I haven't included the set_fs stuff because the base branch it depends on
 hasn't been merged yet.  I'll probably have another merge window PR, as
 there's more in flight (most notably the fix for new binutils I just sent out),
 but I figured there was no reason to delay this any longer.

Linus Torvalds
bbe85027ce Recalling the first round of new code for 5.10, in which we added:
- New feature: Widen inode timestamps and quota grace expiration
   timestamps to support dates through the year 2486.
 - New feature: storing inode btree counts in the AGI to speed up certain
   mount time per-AG block reservation operatoins and add a little more
   metadata redundancy.
 
 For the second round of new code for 5.10:
 - Deprecate the V4 filesystem format, some disused mount options, and some
   legacy sysctl knobs now that we can support dates into the 25th century.
   Note that removal of V4 support will not happen until the early 2030s.
 - Fix some probles with inode realtime flag propagation.
 - Fix some buffer handling issues when growing a rt filesystem.
 - Fix a problem where a BMAP_REMAP unmap call would free rt extents even
   though the purpose of BMAP_REMAP is to avoid freeing the blocks.
 - Strengthen the dabtree online scrubber to check hash values on child
   dabtree blocks.
 - Actually log new intent items created as part of recovering log intent
   items.
 - Fix a bug where quotas weren't attached to an inode undergoing bmap
   intent item recovery.
 - Fix a buffer overrun problem with specially crafted log buffer
   headers.
 - Various cleanups to type usage and slightly inaccurate comments.
 - More cleanups to the xattr, log, and quota code.
 - Don't run the (slower) shared-rmap operations on attr fork mappings.
 - Fix a bug where we failed to check the LSN of finobt blocks during
   replay and could therefore overwrite newer data with older data.
 - Clean up the ugly nested transaction mess that log recovery uses to
   stage intent item recovery in the correct order by creating a proper
   data structure to capture recovered chains.
 - Use the capture structure to resume intent item chains with the
   same log space and block reservations as when they were captured.
 - Fix a UAF bug in bmap intent item recovery where we failed to maintain
   our reference to the incore inode if the bmap operation needed to
   relog itself to continue.
 - Rearrange the defer ops mechanism to finish newly created subtasks
   of a parent task before moving on to the next parent task.
 - Automatically relog intent items in deferred ops chains if doing so
   would help us avoid pinning the log tail.  This will help fix some
   log scaling problems now and will facilitate atomic file updates later.
 - Fix a deadlock in the GETFSMAP implementation by using an internal
   memory buffer to reduce indirect calls and copies to userspace,
   thereby improving its performance by ~20%.
 - Fix various problems when calling growfs on a realtime volume would
   not fully update the filesystem metadata.
 - Fix broken Kconfig asking about deprecated XFS when XFS is disabled.

Merge tag 'xfs-5.10-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull more xfs updates from Darrick Wong:
 "The second large pile of new stuff for 5.10, with changes even more
  monumental than last week!

  We are formally announcing the deprecation of the V4 filesystem format
  in 2030. All users must upgrade to the V5 format, which contains
  design improvements that greatly strengthen metadata validation,
  supports reflink and online fsck, and is the intended vehicle for
  handling timestamps past 2038. We're also deprecating the old Irix
  behavioral tweaks in September 2025.

  Coming along for the ride are two design changes to the deferred
  metadata ops subsystem. One of the improvements is to retain correct
  logical ordering of tasks and subtasks, which is a more logical design
  for upper layers of XFS and will become necessary when we add atomic
  file range swaps and commits. The second improvement to deferred ops
  improves the scalability of the log by helping the log tail to move
  forward during long-running operations. This reduces log contention
  when there are a large number of threads trying to run transactions.

  In addition to that, this fixes numerous small bugs in log recovery;
  refactors logical intent log item recovery to remove the last
  remaining place in XFS where we could have nested transactions; fixes
  a couple of ways that intent log item recovery could fail in ways that
  wouldn't have happened in the regular commit paths; fixes a deadlock
  vector in the GETFSMAP implementation (which improves its performance
  by 20%); and fixes serious bugs in the realtime growfs, fallocate, and
  bitmap handling code.

  Summary:

   - Deprecate the V4 filesystem format, some disused mount options, and
     some legacy sysctl knobs now that we can support dates into the
     25th century. Note that removal of V4 support will not happen until
     the early 2030s.

   - Fix some probles with inode realtime flag propagation.

   - Fix some buffer handling issues when growing a rt filesystem.

   - Fix a problem where a BMAP_REMAP unmap call would free rt extents
     even though the purpose of BMAP_REMAP is to avoid freeing the
     blocks.

   - Strengthen the dabtree online scrubber to check hash values on
     child dabtree blocks.

   - Actually log new intent items created as part of recovering log
     intent items.

   - Fix a bug where quotas weren't attached to an inode undergoing bmap
     intent item recovery.

   - Fix a buffer overrun problem with specially crafted log buffer
     headers.

   - Various cleanups to type usage and slightly inaccurate comments.

   - More cleanups to the xattr, log, and quota code.

   - Don't run the (slower) shared-rmap operations on attr fork
     mappings.

   - Fix a bug where we failed to check the LSN of finobt blocks during
     replay and could therefore overwrite newer data with older data.

   - Clean up the ugly nested transaction mess that log recovery uses to
     stage intent item recovery in the correct order by creating a
     proper data structure to capture recovered chains.

   - Use the capture structure to resume intent item chains with the
     same log space and block reservations as when they were captured.

   - Fix a UAF bug in bmap intent item recovery where we failed to
     maintain our reference to the incore inode if the bmap operation
     needed to relog itself to continue.

This pull request introduces the following changes to zonefs:
 
 * Add the "explicit-open" mount option to automatically issue a
   REQ_OP_ZONE_OPEN command to the device whenever a sequential zone file
   is open for writing for the first time. This avoids "insufficient zone
   resources" errors for write operations on some drives with limited
   zone resources or on ZNS drives with a limited number of active zones.
