Pull btrfs updates from David Sterba:
 "This end of the year branch is intentionally not that exciting. Most
  of the changes are under the hood, but there are some minor user
  visible improvements and several performance improvements too.

  Features:

   - make send work with concurrent block group relocation.

     We're not allowed to prevent send failing or silently producing
     some bad stream but with more fine grained locking and checks it's
     possible. The send vs deduplication exclusion could reuse the same
     logic in the future.

   - new exclusive operation 'balance paused' to allow adding a device
     to filesystem with paused balance

   - new sysfs file for fsid stored in the per-device directory to help
     distinguish devices when seeding is enabled, the fsid may differ
     from the one reported by the filesystem

  Performance improvements:

   - less metadata needed for directory logging, directory deletion is
     20-40% faster

   - in zoned mode, cache zone information during mount to speed up
     repeated queries (about 50% speedup)

   - free space tree entries get indexed and searched by size (latency
     -30%, search run time -30%)

   - less contention in tree node locking when inserting a key and no
     splits are needed (files/sec in fsmark improves by 1-20%)

  Fixes:

   - fix ENOSPC failure when attempting direct IO write into NOCOW range

   - fix deadlock between quota enable and other quota operations

   - global reserve minimum calculations fixed to account for free space
     tree

   - in zoned mode, fix condition for chunk allocation that may not find
     the right zone for reuse and could lead to early ENOSPC

  Core:

   - global reserve stealing got simplified and cleaned up in evict

   - remove async transaction commit based on manual transaction refs,
     reuse existing kthread and mechanisms to let it commit transaction
     before timeout

   - preparatory work for extent tree v2, add wrappers for global tree
     roots, truncation path cleanups

   - remove readahead framework, it's a bit overengineered and used only
     for scrub, and yet it does not cover all its needs, there is
     another readahead built in the b-tree search that is now used,
     performance drop on HDD is about 5% which is acceptable and scrub
     is often throttled anyway, on SSDs there's no reported drop but
     slight improvement

   - self tests report extent tree state when error occurs

   - replace assert with debugging information when an uncommitted
     transaction is found at unmount time

  Other:

   - error handling improvements

   - other cleanups and refactoring"

* tag 'for-5.17-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (115 commits)
  btrfs: output more debug messages for uncommitted transaction
  btrfs: respect the max size in the header when activating swap file
  btrfs: fix argument list that the kdoc format and script verified
  btrfs: remove unnecessary parameter type from compression_decompress_bio
  btrfs: selftests: dump extent io tree if extent-io-tree test failed
  btrfs: scrub: cleanup the argument list of scrub_stripe()
  btrfs: scrub: cleanup the argument list of scrub_chunk()
  btrfs: remove reada infrastructure
  btrfs: scrub: use btrfs_path::reada for extent tree readahead
  btrfs: scrub: remove the unnecessary path parameter for scrub_raid56_parity()
  btrfs: refactor unlock_up
  btrfs: skip transaction commit after failure to create subvolume
  btrfs: zoned: fix chunk allocation condition for zoned allocator
  btrfs: add extent allocator hook to decide to allocate chunk or not
  btrfs: zoned: unset dedicated block group on allocation failure
  btrfs: zoned: drop redundant check for REQ_OP_ZONE_APPEND and btrfs_is_zoned
  btrfs: zoned: sink zone check into btrfs_repair_one_zone
  btrfs: zoned: simplify btrfs_check_meta_write_pointer
  btrfs: zoned: encapsulate inode locking for zoned relocation
  btrfs: sysfs: add devinfo/fsid to retrieve actual fsid from the device

8efd0d9c31 Networking changes for 5.17.
Core
 ----
 
  - Defer freeing TCP skbs to the BH handler, whenever possible,
    or at least perform the freeing outside of the socket lock section
    to decrease cross-CPU allocator work and improve latency.
 
  - Add netdevice refcount tracking to locate sources of netdevice
    and net namespace refcount leaks.
 
  - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
    all queues from a single CPU removing latency spikes.
 
  - Various small optimizations throughout the stack from Eric Dumazet.
 
  - Make netdev->dev_addr[] constant, force modifications to go via
    appropriate helpers to allow us to keep addresses in ordered data
    structures.
 
  - Replace unix_table_lock with per-hash locks, improving performance
    of bind() calls.
 
  - Extend skb drop tracepoint with a drop reason.
 
  - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
 
 BPF
 ---
 
  - New helpers:
    - bpf_find_vma(), find and inspect VMAs for profiling use cases
    - bpf_loop(), runtime-bounded loop helper trading some execution
      time for much faster (if at all converging) verification
    - bpf_strncmp(), improve performance, avoid compiler flakiness
    - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
      for tracing programs, all inlined by the verifier
 
  - Support BPF relocations (CO-RE) in the kernel loader.
 
  - Further the support for BTF_TYPE_TAG annotations.
 
  - Allow access to local storage in sleepable helpers.
 
  - Convert verifier argument types to a composable form with different
    attributes which can be shared across types (ro, maybe-null).
 
  - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
    creating new, extensible ones where missing and deprecating those
    to be removed.

  - Bluetooth:
    - rework of HCI command execution serialization to use a common
      queue and work struct, and improve handling errors reported
      in the middle of a batch of commands
    - rework HCI event handling to use skb_pull_data, avoiding packet
      parsing pitfalls

      connection, similar to TCP RST in regular TCP)
 
  - MCTP (Management Component Transport) over serial, as defined by
    DMTF spec DSP0253 - "MCTP Serial Transport Binding".
 
 Driver API
 ----------
 
  - Support timestamping on bond interfaces in active/passive mode.
 
  - Introduce generic phylink link mode validation for drivers which
    don't have any quirks and where MAC capability bits fully express
    what's supported. Allow PCS layer to participate in the validation.

     appropriate helpers to allow us to keep addresses in ordered data
     structures.

   - Replace unix_table_lock with per-hash locks, improving performance
     of bind() calls.

   - Extend skb drop tracepoint with a drop reason.

   - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.

  BPF
  ---

   - New helpers:
      - bpf_find_vma(), find and inspect VMAs for profiling use cases
      - bpf_loop(), runtime-bounded loop helper trading some execution
        time for much faster (if at all converging) verification
      - bpf_strncmp(), improve performance, avoid compiler flakiness
      - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
        for tracing programs, all inlined by the verifier

   - Support BPF relocations (CO-RE) in the kernel loader.

   - Further the support for BTF_TYPE_TAG annotations.

   - Allow access to local storage in sleepable helpers.

   - Convert verifier argument types to a composable form with different
     attributes which can be shared across types (ro, maybe-null).

   - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
     creating new, extensible ones where missing and deprecating those
     to be removed.

  Protocols
  ---------

   - WiFi (mac80211/cfg80211):
      - notify user space about long "come back in N" AP responses,
        allow it to react to such temporary rejections
      - allow non-standard VHT MCS 10/11 rates
      - use coarse time in airtime fairness code to save CPU cycles

   - Bluetooth:
      - rework of HCI command execution serialization to use a common
        queue and work struct, and improve handling errors reported in
        the middle of a batch of commands
      - rework HCI event handling to use skb_pull_data, avoiding packet
        parsing pitfalls
      - support AOSP Bluetooth Quality Report

   - SMC:
      - support net namespaces, following the RDMA model
      - improve connection establishment latency by pre-clearing buffers
      - introduce TCP ULP for automatic redirection to SMC

   - Multi-Path TCP:
      - support ioctls: SIOCINQ, OUTQ, and OUTQNSD
      - support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
        IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
      - support cmsgs: TCP_INQ
      - improvements in the data scheduler (assigning data to subflows)
      - support fastclose option (quick shutdown of the full MPTCP
        connection, similar to TCP RST in regular TCP)

   - MCTP (Management Component Transport) over serial, as defined by
     DMTF spec DSP0253 - "MCTP Serial Transport Binding".

  Driver API
  ----------

   - Support timestamping on bond interfaces in active/passive mode.

   - Introduce generic phylink link mode validation for drivers which
     don't have any quirks and where MAC capability bits fully express
     what's supported. Allow PCS layer to participate in the validation.
     Convert a number of drivers.

   - Add support to set/get size of buffers on the Rx rings and size of
     the tx copybreak buffer via ethtool.

   - Support offloading TC actions as first-class citizens rather than
     only as attributes of filters, improve sharing and device resource
     utilization.

   - WiFi (mac80211/cfg80211):
      - support forwarding offload (ndo_fill_forward_path)

eac1b93c14 gro: add ability to control gro max packet size
Eric Dumazet suggested to allow users to modify max GRO packet size.

We have seen GRO being disabled by users of appliances (such as
wifi access points) because of claimed bufferbloat issues,
or some work arounds in sch_cake, to split GRO/GSO packets.

Instead of disabling GRO completely, one can chose to limit
the maximum packet size of GRO packets, depending on their
latency constraints.

This patch adds a per device gro_max_size attribute
that can be changed with ip link command.

ip link set dev eth0 gro_max_size 16000

383f0993fc can: netlink: report the CAN controller mode supported flags
Currently, the CAN netlink interface provides no easy ways to check
the capabilities of a given controller. The only method from the
command line is to try each CAN_CTRLMODE_* individually to check
whether the netlink interface returns an -EOPNOTSUPP error or not
(alternatively, one may find it easier to directly check the source
code of the driver instead...)

This patch introduces a method for the user to check both the
supported and the static capabilities. The proposed method introduces
a new IFLA nest: IFLA_CAN_CTRLMODE_EXT which extends the current
IFLA_CAN_CTRLMODE. This is done to guaranty a full forward and
backward compatibility between the kernel and the user land
applications.

The IFLA_CAN_CTRLMODE_EXT nest contains one single entry:
IFLA_CAN_CTRLMODE_SUPPORTED. Because this entry is only used in one
direction: kernel to userland, no new struct nla_policy are
introduced.

Below table explains how IFLA_CAN_CTRLMODE_SUPPORTED (hereafter:
"supported") and can_ctrlmode::flags (hereafter: "flags") allow us to
identify both the supported and the static capabilities, when masked
with any of the CAN_CTRLMODE_* bit flags:

 supported &	flags &		Controller capabilities
 CAN_CTRLMODE_*	CAN_CTRLMODE_*
 -----------------------------------------------------------------------
 false		false		Feature not supported (always disabled)
 false		true		Static feature (always enabled)
 true		false		Feature supported but disabled
 true		true		Feature supported and enabled

5bc03b28ec nl80211: clarify comment for mesh PLINK_BLOCKED state
When a mesh link is in blocked state, it is very useful to still allow
auth requests from the peer to re-establish it.
When a remote node is power cycled, the peer state can easily end up
in blocked state if multiple auth attempts are performed. Since this
can lead to several minutes of downtime, we should accept auth attempts
of the peer after it has come back.

ccae4a19c9 btrfs: remove no longer needed logic for replaying directory deletes
Now that we log only dir index keys when logging a directory, we no longer
need to deal with dir item keys in the log replay code for replaying
directory deletes. This is also true for the case when we replay a log
tree created by a kernel that still logs dir items.

So remove the remaining code of the replay of directory deletes algorithm
that deals with dir item keys.

4e484b3e96 xfrm: rate limit SA mapping change message to user space
Kernel generates mapping change message, XFRM_MSG_MAPPING,
when a source port chage is detected on a input state with UDP
encapsulation set.  Kernel generates a message for each IPsec packet
with new source port.  For a high speed flow per packet mapping change
message can be excessive, and can overload the user space listener.

Introduce rate limiting for XFRM_MSG_MAPPING message to the user space.

The rate limiting is configurable via netlink, when adding a new SA or
updating it. Use the new attribute XFRMA_MTIMER_THRESH in seconds.

v1->v2 change:
	update xfrm_sa_len()

v2->v3 changes:
	use u32 insted unsigned long to reduce size of struct xfrm_state
	fix xfrm_ompat size Reported-by: kernel test robot <lkp@intel.com>

d9a8297e87 nl82011: clarify interface combinations wrt. channels
Thinking about MLD (Draft 802.11be) now, it's clear that
we'll have new limitations where different stations (or
links) must be on _different_ channels (or in different
frequency ranges even.) Clarify that the current limit of
multiple channels is a maximum and the same one is OK.

87c1aec15d nl80211: Add support to offload SA Query procedures for AP SME device
Add a flag attribute to use in ap settings to indicate userspace
supports offloading of SA Query procedures to driver. Also add AP SME
device feature flag to advertise that the SA Query procedures offloaded
to driver when userspace indicates support for offloading of SA Query
procedures.

Driver handles SA Query procedures in driver's SME it self and skip
sending SA Query request or response frames to userspace when userspace
indicates support for SA Query procedures offload. But if userspace
doesn't advertise support for SA Query procedures offload driver shall
not offload SA Query procedures handling.

Also userspace with SA Query procedures offload capability shall skip SA
Query specific validations when driver indicates support for handling SA
Query procedures.

In previous method each AP settings flag is represented by a top-level
flag attribute and conversion to enum cfg80211_ap_settings_flags had to
be done before sending them to driver. This commit is to make it easier
to define new AP settings flags and sending them to driver.

a95bfb876f cfg80211: rename offchannel_chain structs to background_chain to avoid confusion with ETSI standard
ETSI standard defines "Offchannel CAC" as:
"Off-Channel CAC is performed by a number of non-continuous checks
spread over a period in time. This period, which is required to
determine the presence of radar signals, is defined as the Off-Channel
CAC Time..
Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time
4 hours..".
mac80211 implementation refers to a dedicated hw chain used for continuous
radar monitoring. Rename offchannel_* references to background_* in
order to avoid confusion with ETSI standard.

a083ee8a4e cfg80211: Add support for notifying association comeback
Thought the underline driver MLME can handle association temporal
rejection with comeback, it is still useful to notify this to
user space, as user space might want to handle the temporal
rejection differently. For example, in case the comeback time
is too long, user space can deauthenticate immediately and try
to associate with a different AP.

9c9211a3fc net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX
Since commit 94dd016ae5 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP
ioctl to active device") the user could get bond active interface's
PHC index directly. But when there is a failover, the bond active
interface will change, thus the PHC index is also changed. This may
break the user's program if they did not update the PHC timely.

This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX.
When the user wants to get the bond active interface's PHC, they need to
add this flag and be aware the PHC index may be changed.

With the new flag. All flag checks in current drivers are removed. Only
the checking in net_hwtstamp_validate() is kept.

43d5ac7d07 drm: document DRM_IOCTL_MODE_GETFB2
There are a few details specific to the GETFB2 IOCTL.

It's not immediately clear how user-space should check for the
number of planes. Suggest using the handles field or the pitches
field.

The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR.
So explicitly tell user-space to not look at it unless the flag is
set.

Changes in v2 (Daniel):
- Mention that handles should be used to compute the number of planes,
  and only refer to pitches as a fallback.
- Reword bit about undefined modifier.

f92c1e1836 bpf: Add get_func_[arg|ret|arg_cnt] helpers
Adding following helpers for tracing programs:

Get n-th argument of the traced function:
  long bpf_get_func_arg(void *ctx, u32 n, u64 *value)

Get return value of the traced function:
  long bpf_get_func_ret(void *ctx, u64 *value)

Get arguments count of the traced function:
  long bpf_get_func_arg_cnt(void *ctx)

The trampoline now stores number of arguments on ctx-8
address, so it's easy to verify argument index and find
return value argument's position.

Moving function ip address on the trampoline stack behind
the number of functions arguments, so it's now stored on
ctx-16 address if it's needed.

All helpers above are inlined by verifier.

Also bit unrelated small change - using newly added function
bpf_prog_has_trampoline in check_get_func_ip.

c5fb199374 bpf: Add bpf_strncmp helper
The helper compares two strings: one string is a null-terminated
read-only string, and another string has const max storage size
but doesn't need to be null-terminated. It can be used to compare
file name in tracing or LSM program.

9dcc38e281 Increase default MLOCK_LIMIT to 8 MiB
This limit has not been updated since 2008, when it was increased to 64
KiB at the request of GnuPG.  Until recently, the main use-cases for this
feature were (1) preventing sensitive memory from being swapped, as in
GnuPG's use-case; and (2) real-time use-cases.  In the first case, little
memory is called for, and in the second case, the user is generally in a
position to increase it if they need more.

The introduction of IOURING_REGISTER_BUFFERS adds a third use-case:
preparing fixed buffers for high-performance I/O.  This use-case will take
as much of this memory as it can get, but is still limited to 64 KiB by
default, which is very little.  This increases the limit to 8 MB, which
was chosen fairly arbitrarily as a more generous, but still conservative,
default value.

It is also possible to raise this limit in userspace.  This is easily
done, for example, in the use-case of a network daemon: systemd, for
instance, provides for this via LimitMEMLOCK in the service file; OpenRC
via the rc_ulimit variables.  However, there is no established userspace
facility for configuring this outside of daemons: end-user applications do
not presently have access to a convenient means of raising their limits.

The buck, as it were, stops with the kernel.  It's much easier to address
it here than it is to bring it to hundreds of distributions, and it can
only realistically be relied upon to be high-enough by end-user software
if it is more-or-less ubiquitous.  Most distros don't change this
particular rlimit from the kernel-supplied default value, so a change here
will easily provide that ubiquity.
