ba1dc7f273 Char / Misc driver changes for 5.15-rc1 
Here is the big set of char/misc driver changes for 5.15-rc1.
 
 Lots of different driver subsystems are being updated in here, notably:
 	- mhi subsystem update
 	- fpga subsystem update
 	- coresight/hwtracing subsystem update
 	- interconnect subsystem update
 	- nvmem subsystem update
 	- parport drivers update
 	- phy subsystem update
 	- soundwire subsystem update
 and there are some other char/misc drivers being updated as well:
 	- binder driver additions
 	- new misc drivers
 	- lkdtm driver updates
 	- mei driver updates
 	- sram driver updates
 	- other minor driver updates.
 
 Note, there are no habanna labs driver updates in this pull request,
 that will probably come later before -rc1 is out in a different request.
 
 All of these have been in linux-next for a while with no reported
 problems.

efa916af13 - Add DM infrastructure for IMA-based remote attestion. These changes 
are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured
   via IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).
 
 - Fix DM crypt scalability regression on systems with many cpus due to
   percpu_counter spinlock contention in crypt_page_alloc().
 
 - Use in_hardirq() instead of deprecated in_irq() in DM crypt.
 
 - Add event counters to DM writecache to allow users to further assess
   how the writecache is performing.

Pull idmapping documentation updates from Christian Brauner:
 "The bulk of the idmapped work this cycle was adding support for
  idmapped mounts to btrfs.

  While this required the addition of a (simple) new vfs helper all the
  work is going through David Sterba's btrfs tree. It was way simpler to
  do it this way rather then forcing David to coordinate between his
  btrfs and my tree. Plus I don't care who merges it as long as I feel I
  can trust the maintainer and the btrfs folks were really fast and
  helpful in reviewing this work.

  As always, associated with the btrfs port for idmapped mounts is a new
  fstests extension specifically concerned with btrfs ioctls (e.g.
  subvolume creation, deletion etc.) on idmapped mounts which can be
  found in the fstests repo as 5f8179ce8b00 ("btrfs: introduce btrfs
  specific idmapped mounts tests").

  Consequently, this cycle the idmapping pull is boring. It only
  contains documentation updates, specifically about how idmappings and
  idmapped mounts work"

Pull close_range() cleanup from Christian Brauner:
 "This is a cleanup for close_range() which was sent as part of a bugfix
  we did some time ago in commit 9b5b872215 ("file: fix close_range()
  for unshare+cloexec").

  We used to share more code between some helpers for close_range()
  which made retrieving the maximum number of open fds before calling
  into the helpers sensible. But with the introduction of
  CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds
  once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the
  code was in a dumb in-limbo state.

  Fix this by simplifying the code a bit.

  The original idea was to only fix the bug itself and make backporting
  easy. And since the cleanup wasn't very pressing I left it in
  linux-next for a very long time. I didn't pull the patches from the
  list again back then which is why they don't have lore-links. So I'm
  listing them below explicitly"

Pull move_mount updates from Christian Brauner:
 "This contains an extension to the move_mount() syscall making it
  possible to add a single private mount into an existing propagation
  tree.

  The use-case comes from the criu folks which have been struggling with
  restoring complex mount trees for a long time. Variations of this work
  have been discussed at Plumbers before, e.g.

      https://www.linuxplumbersconf.org/event/7/contributions/640/

  The extension to move_mount() enables criu to restore any set of mount
  namespaces, mount trees and sharing group trees without introducing
  yet more complexity into mount propagation itself.

  The changes required to criu to make use of this and restore complex
  propagation trees are available at

      https://github.com/Snorch/criu/commits/mount-v2-poc

Pull iomap updates from Darrick Wong:
 "The most notable externally visible change for this cycle is the
  addition of support for reads to inline tail fragments of files, which
  was requested by the erofs developers; and a correction for a kernel
  memory corruption bug if the sysadmin tries to activate a swapfile
  with more pages than the swapfile header suggests.

  We also now report writeback completion errors to the file mapping
  correctly, instead of munging all errors into EIO.

  Internally, the bulk of the changes are Christoph's patchset to reduce
  the indirect function call count by a third to a half by converting
  iomap iteration from a loop pattern to a generator/consumer pattern.
  As an added bonus, fsdax no longer open-codes iomap apply loops.

  Summary:

   - Simplify the bio_end_page usage in the buffered IO code.

   - Support reading inline data at nonzero offsets for erofs.

   - Fix some typos and bad grammar.

   - Convert kmap_atomic usage in the inline data read path.

Pull btrfs updates from David Sterba:
 "The highlights of this round are integrations with fs-verity and
  idmapped mounts, the rest is usual mix of minor improvements, speedups
  and cleanups.

  There are some patches outside of btrfs, namely updating some VFS
  interfaces, all straightforward and acked.

  Features:

   - fs-verity support, using standard ioctls, backward compatible with
     read-only limitation on inodes with previously enabled fs-verity

   - idmapped mount support

   - make mount with rescue=ibadroots more tolerant to partially damaged
     trees

   - allow raid0 on a single device and raid10 on two devices,
     degenerate cases but might be useful as an intermediate step during
     conversion to other profiles

   - zoned mode block group auto reclaim can be disabled via sysfs knob

  Performance improvements:

   - continue readahead of node siblings even if target node is in
     memory, could speed up full send (on sample test +11%)

   - batching of delayed items can speed up creating many files

   - fsync/tree-log speedups
       - avoid unnecessary work (gains +2% throughput, -2% run time on
         sample load)
       - reduced lock contention on renames (on dbench +4% throughput,
         up to -30% latency)

  Fixes:

   - various zoned mode fixes

   - preemptive flushing threshold tuning, avoid excessive work on
     almost full filesystems

  Core:

   - continued subpage support, preparation for implementing remaining
     features like compression and defragmentation; with some
     limitations, write is now enabled on 64K page systems with 4K
     sectors, still considered experimental
       - no readahead on compressed reads
       - inline extents disabled
       - disabled raid56 profile conversion and mount

   - improved flushing logic, fixing early ENOSPC on some workloads

   - inode flags have been internally split to read-only and read-write
     incompat bit parts, used by fs-verity

   - new tree items for fs-verity
       - descriptor item
       - Merkle tree item

   - inode operations extended to be namespace-aware

   - cleanups and refactoring

  Generic code changes:

   - fs: new export filemap_fdatawrite_wbc

   - fs: removed sync_inode

   - block: bio_trim argument type fixups

   - vfs: add namespace-aware lookup"

Merge tag '5.15-rc-first-ksmbd-merge' of git://git.samba.org/ksmbd

Pull initial ksmbd implementation from Steve French:
 "Initial merge of kernel smb3 file server, ksmbd.

  The SMB family of protocols is the most widely deployed network
  filesystem protocol, the default on Windows and Macs (and even on many
  phones and tablets), with clients and servers on all major operating
  systems, but lacked a kernel server for Linux. For many cases the
  current userspace server choices were suboptimal either due to memory
  footprint, performance or difficulty integrating well with advanced
  Linux features.

  ksmbd is a new kernel module which implements the server-side of the
  SMB3 protocol. The target is to provide optimized performance, GPLv2
  SMB server, and better lease handling (distributed caching). The
  bigger goal is to add new features more rapidly (e.g. RDMA aka
  "smbdirect", and recent encryption and signing improvements to the
  protocol) which are easier to develop on a smaller, more tightly
  optimized kernel server than for example in Samba.

  The Samba project is much broader in scope (tools, security services,
  LDAP, Active Directory Domain Controller, and a cross platform file
  server for a wider variety of purposes) but the user space file server
  portion of Samba has proved hard to optimize for some Linux workloads,
  including for smaller devices.

  This is not meant to replace Samba, but rather be an extension to
  allow better optimizing for Linux, and will continue to integrate well
  with Samba user space tools and libraries where appropriate. Working
  with the Samba team we have already made sure that the configuration
  files and xattrs are in a compatible format between the kernel and
  user space server.

  Various types of functional and regression tests are regularly run
  against it. One example is the automated 'buildbot' regression tests
  which use the Linux client to test against ksmbd, e.g.

     http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56

  but other test suites, including Samba's smbtorture functional test
  suite are also used regularly"

Subbaraya Sundeep says:

====================
octeontx2-af: Miscellaneous fixes in npc

This patchset consists of consolidated fixes in
rvu_npc file. Two of the patches prevent infinite
loop which can happen in corner cases. One patch
is for fixing static code analyzer reported issues.
And the last patch is a minor change in npc protocol
checker hardware block to report ipv4 checksum errors
as a known error codes.

1e4428b6db octeontx2-af: Set proper errorcode for IPv4 checksum errors 
With current config, for packets with IPv4 checksum errors,
errorcode is being set to UNKNOWN. Hence added a separate
errorcodes for outer and inner IPv4 checksum and changed
NPC configuration accordingly.

Also turn on L2 multicast address check in NPC protocol check block.

f2e4568ec9 octeontx2-af: Fix mailbox errors in nix_rss_flowkey_cfg 
In npc_update_vf_flow_entry function the loop cursor
'index' is being changed inside the loop causing
the loop to spin forever. This in turn hogs the kworker
thread forever and no other mbox message is processed
by AF driver after that. Fix this by using
another variable in the loop.

dc56ad7028 af_unix: fix potential NULL deref in unix_dgram_connect() 
syzbot was able to trigger NULL deref in unix_dgram_connect() [1]

This happens in

	if (unix_peer(sk))
		sk->sk_state = other->sk_state = TCP_ESTABLISHED; // crash because @other is NULL

Because locks have been dropped, unix_peer() might be non NULL,
while @other is NULL (AF_UNSPEC case)

We need to move code around, so that we no longer access
unix_peer() and sk_state while locks have been released.

995786ba0d dpaa2-eth: Replace strlcpy with strscpy 
The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.

But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.

Thus, We prefer using strscpy instead of strlcpy.
