net: fec: check the return value of build_skb()

The build_skb might return a null pointer but there is no check on the
return value in the fec_enet_rx_queue(). So a null pointer dereference
might occur. To avoid this, we check the return value of build_skb. If
the return value is a null pointer, the driver will recycle the page and
update the statistic of ndev. Then jump to rx_processing_done to clear
the status flags of the BD so that the hardware can recycle the BD.

Merge branch 'stop-corrupting-socket-s-task_frag'

Benjamin Coddington says:

====================
Stop corrupting socket's task_frag

The networking code uses flags in sk_allocation to determine if it can use
current->task_frag, however in-kernel users of sockets may stop setting
sk_allocation when they convert to the preferred memalloc_nofs_save/restore,
as SUNRPC has done in commit a1231fda7e94 ("SUNRPC: Set memalloc_nofs_save()
on all rpciod/xprtiod jobs").

This will cause corruption in current->task_frag when recursing into the
network layer for those subsystems during page fault or reclaim.  The
corruption is difficult to diagnose because stack traces may not contain the
offending subsystem at all.  The corruption is unlikely to show up in
testing because it requires memory pressure, and so subsystems that
convert to memalloc_nofs_save/restore are likely to continue to run into
this issue.

Treewide: Stop corrupting socket's task_frag

Since moving to memalloc_nofs_save/restore, SUNRPC has stopped setting the
GFP_NOIO flag on sk_allocation which the networking system uses to decide
when it is safe to use current->task_frag.  The results of this are
unexpected corruption in task_frag when SUNRPC is involved in memory
reclaim.

The corruption can be seen in crashes, but the root cause is often
difficult to ascertain as a crashing machine's stack trace will have no
evidence of being near NFS or SUNRPC code.  I believe this problem to
be much more pervasive than reports to the community may indicate.

Fix this by having kernel users of sockets that may corrupt task_frag due
to reclaim set sk_use_task_frag = false.  Preemptively correcting this
situation for users that still set sk_allocation allows them to convert to
memalloc_nofs_save/restore without the same unexpected corruptions that are
sure to follow, unlikely to show up in testing, and difficult to bisect.

net: Introduce sk_use_task_frag in struct sock.

Sockets that can be used while recursing into memory reclaim, like
those used by network block devices and file systems, mustn't use
current->task_frag: if the current process is already using it, then
the inner memory reclaim call would corrupt the task_frag structure.

To avoid this, sk_page_frag() uses ->sk_allocation to detect sockets
that mustn't use current->task_frag, assuming that those used during
memory reclaim had their allocation constraints reflected in
->sk_allocation.

This unfortunately doesn't cover all cases: in an attempt to remove all
usage of GFP_NOFS and GFP_NOIO, sunrpc stopped setting these flags in
->sk_allocation, and used memalloc_nofs critical sections instead.
This breaks the sk_page_frag() heuristic since the allocation
constraints are now stored in current->flags, which sk_page_frag()
can't read without risking triggering a cache miss and slowing down
TCP's fast path.

This patch creates a new field in struct sock, named sk_use_task_frag,
which sockets with memory reclaim constraints can set to false if they
can't safely use current->task_frag. In such cases, sk_page_frag() now
always returns the socket's page_frag (->sk_frag). The first user is
sunrpc, which needs to avoid using current->task_frag but can keep
->sk_allocation set to GFP_KERNEL otherwise.

Eventually, it might be possible to simplify sk_page_frag() by only
testing ->sk_use_task_frag and avoid relying on the ->sk_allocation
heuristic entirely (assuming other sockets will set ->sk_use_task_frag
according to their constraints in the future).

The new ->sk_use_task_frag field is placed in a hole in struct sock and
belongs to a cache line shared with ->sk_shutdown. Therefore it should
be hot and shouldn't have negative performance impacts on TCP's fast
path (sk_shutdown is tested just before the while() loop in
tcp_sendmsg_locked()).

net: stream: purge sk_error_queue in sk_stream_kill_queues()

Changheon Lee reported TCP socket leaks, with a nice repro.

It seems we leak TCP sockets with the following sequence:

1) SOF_TIMESTAMPING_TX_ACK is enabled on the socket.

   Each ACK will cook an skb put in error queue, from __skb_tstamp_tx().
   __skb_tstamp_tx() is using skb_clone(), unless
   SOF_TIMESTAMPING_OPT_TSONLY was also requested.

2) If the application is also using MSG_ZEROCOPY, then we put in the
   error queue cloned skbs that had a struct ubuf_info attached to them.

   Whenever an struct ubuf_info is allocated, sock_zerocopy_alloc()
   does a sock_hold().

   As long as the cloned skbs are still in sk_error_queue,
   socket refcount is kept elevated.

3) Application closes the socket, while error queue is not empty.

Since tcp_close() no longer purges the socket error queue,
we might end up with a TCP socket with at least one skb in
error queue keeping the socket alive forever.

This bug can be (ab)used to consume all kernel memory
and freeze the host.

We need to purge the error queue, with proper synchronization
against concurrent writers.

rxrpc: Fixes for I/O thread conversion/SACK table expansion

Here are some fixes for AF_RXRPC:

(1) Fix missing unlock in rxrpc's sendmsg.

(2) Fix (lack of) propagation of security settings to rxrpc_call.

(3) Fix NULL ptr deref in rxrpc_unuse_local().

(4) Fix problem with kthread_run() not invoking the I/O thread function if
     the kthread gets stopped first.  Possibly this should actually be
     fixed in the kthread code.

(5) Fix locking problem as putting a peer (which may be done from RCU) may
     now invoke kthread_stop().

(6) Fix switched parameters in a couple of trace calls.

(7) Fix I/O thread's checking for kthread stop to make sure it completes
     all outstanding work before returning so that calls are cleaned up.

(8) Fix an uninitialised var in the new rxperf test server.

(9) Fix the return value of rxrpc_new_incoming_call() so that the checks
     on it work correctly.

The patches fix at least one syzbot bug[1] and probably some others that
don't have reproducers[2][3][4].  I think it also fixes another[5], but
that showed another failure during testing that was different to the
original.

There's also an outstanding bug in rxrpc_put_peer()[6] that is fixed by a

rxrpc: Fix I/O thread stop

The rxrpc I/O thread checks to see if there's any work it needs to do, and
if not, checks kthread_should_stop() before scheduling, and if it should
stop, breaks out of the loop and tries to clean up and exit.

This can, however, race with socket destruction, wherein outstanding calls
are aborted and released from the socket and then the socket unuses the
local endpoint, causing kthread_stop() to be issued.  The abort is deferred
to the I/O thread and the event can by issued between the I/O thread
checking if there's any work to be done (such as processing call aborts)
and the stop being seen.

This results in the I/O thread stopping processing of events whilst call
cleanup events are still outstanding, leading to connections or other
objects still being around and uncleaned up, which can result in assertions
being triggered, e.g.:

    rxrpc: AF_RXRPC: Leaked client conn 00000000e8009865 {2}

Fix this by retrieving the kthread_should_stop() indication, then checking
to see if there's more work to do, and going back round the loop if there
is, and breaking out of the loop only if there wasn't.

This was triggered by a syzbot test that produced some other symptom[1].

rxrpc: Fix locking issues in rxrpc_put_peer_locked()

Now that rxrpc_put_local() may call kthread_stop(), it can't be called
under spinlock as it might sleep. This can cause a problem in the peer
keepalive code in rxrpc as it tries to avoid dropping the peer_hash_lock
from the point it needs to re-add peer->keepalive_link to going round the
loop again in rxrpc_peer_keepalive_dispatch().

Fix this by just dropping the lock when we don't need it and accepting that
we'll have to take it again. This code is only called about every 20s for
each peer, so not very often.

This allows rxrpc_put_peer_unlocked() to be removed also.

rxrpc: Fix I/O thread startup getting skipped

When starting a kthread, the __kthread_create_on_node() function, as called
from kthread_run(), waits for a completion to indicate that the task_struct
(or failure state) of the new kernel thread is available before continuing.

This does not wait, however, for the thread function to be invoked and,
indeed, will skip it if kthread_stop() gets called before it gets there.

If this happens, though, kthread_run() will have returned successfully,
indicating that the thread was started and returning the task_struct
pointer. The actual error indication is returned by kthread_stop().

Note that this is ambiguous, as the caller cannot tell whether the -EINTR
error code came from kthread() or from the thread function.

This was encountered in the new rxrpc I/O thread, where if the system is
being pounded hard by, say, syzbot, the check of KTHREAD_SHOULD_STOP can be
delayed long enough for kthread_stop() to get called when rxrpc releases a
socket - and this causes an oops because the I/O thread function doesn't
get started and thus doesn't remove the rxrpc_local struct from the
local_endpoints list.

Fix this by using a completion to wait for the thread to actually enter
rxrpc_io_thread(). This makes sure the thread can't be prematurely
stopped and makes sure the relied-upon cleanup is done.

rxrpc: Fix missing unlock in rxrpc_do_sendmsg()

Note that this still doesn't get rid of the checker warning:

net_sched: reject TCF_EM_SIMPLE case for complex ematch module

When TCF_EM_SIMPLE was introduced, it is supposed to be convenient
for ematch implementation:

https://lore.kernel.org/all/20050105110048.GO26856@postel.suug.ch/

"You don't have to, providing a 32bit data chunk without TCF_EM_SIMPLE
set will simply result in allocating & copy. It's an optimization,
nothing more."

So if an ematch module provides ops->datalen that means it wants a
complex data structure (saved in its em->data) instead of a simple u32
value. We should simply reject such a combination, otherwise this u32
could be misinterpreted as a pointer.

openvswitch: Fix flow lookup to use unmasked key

The commit mentioned below causes the ovs_flow_tbl_lookup() function
to be called with the masked key. However, it's supposed to be called
with the unmasked key. This due to the fact that the datapath supports
installing wider flows, and OVS relies on this behavior. For example
if ipv4(src=1.1.1.1/192.0.0.0, dst=1.1.1.2/192.0.0.0) exists, a wider
flow (smaller mask) of ipv4(src=192.1.1.1/128.0.0.0,dst=192.1.1.2/
128.0.0.0) is allowed to be added.

However, if we try to add a wildcard rule, the installation fails:

$ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \
ipv4(src=1.1.1.1/192.0.0.0,dst=1.1.1.2/192.0.0.0,frag=no)" 2
$ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \
ipv4(src=192.1.1.1/0.0.0.0,dst=49.1.1.2/0.0.0.0,frag=no)" 2
ovs-vswitchd: updating flow table (File exists)

The reason is that the key used to determine if the flow is already
present in the system uses the original key ANDed with the mask.
This results in the IP address not being part of the (miniflow) key,
i.e., being substituted with an all-zero value. When doing the actual
lookup, this results in the key wrongfully matching the first flow,
and therefore the flow does not get installed.

This change reverses the commit below, but rather than having the key
on the stack, it's allocated.

net: dsa: mv88e6xxx: avoid reg_lock deadlock in mv88e6xxx_setup_port()

In the blamed commit, it was not noticed that one implementation of
chip->info->ops->phylink_get_caps(), called by mv88e6xxx_get_caps(),
may access hardware registers, and in doing so, it takes the
mv88e6xxx_reg_lock(). Namely, this is mv88e6352_phylink_get_caps().

This is a problem because mv88e6xxx_get_caps(), apart from being
a top-level function (method invoked by dsa_switch_ops), is now also
directly called from mv88e6xxx_setup_port(), which runs under the
mv88e6xxx_reg_lock() taken by mv88e6xxx_setup(). Therefore, when running
on mv88e6352, the reg_lock would be acquired a second time and the
system would deadlock on driver probe.

The things that mv88e6xxx_setup() can compete with in terms of register
access with are the IRQ handlers and MDIO bus operations registered by
mv88e6xxx_probe(). So there is a real need to acquire the register lock.

The register lock can, in principle, be dropped and re-acquired pretty
much at will within the driver, as long as no operations that involve
waiting for indirect access to complete (essentially, callers of
mv88e6xxx_smi_direct_wait() and mv88e6xxx_wait_mask()) are interrupted
with the lock released. However, I would guess that in mv88e6xxx_setup(),
the critical section is kept open for such a long time just in order to
optimize away multiple lock/unlock operations on the registers.

We could, in principle, drop the reg_lock right before the
mv88e6xxx_setup_port() -> mv88e6xxx_get_caps() call, and
re-acquire it immediately afterwards. But this would look ugly, because
mv88e6xxx_setup_port() would release a lock which it didn't acquire, but
the caller did.

A cleaner solution to this issue comes from the observation that struct
mv88e6xxxx_ops methods generally assume they are called with the
reg_lock already acquired. Whereas mv88e6352_phylink_get_caps() is more
the exception rather than the norm, in that it acquires the lock itself.

Let's enforce the same locking pattern/convention for
chip->info->ops->phylink_get_caps() as well, and make
mv88e6xxx_get_caps(), the top-level function, acquire the register lock
explicitly, for this one implementation that will access registers for
port 4 to work properly.

This means that mv88e6xxx_setup_port() will no longer call the top-level
function, but the low-level mv88e6xxx_ops method which expects the
correct calling context (register lock held).

Compared to chip->info->ops->phylink_get_caps(), mv88e6xxx_get_caps()
also fixes up the supported_interfaces bitmap for internal ports, since
that can be done generically and does not require per-switch knowledge.
That's code which will no longer execute, however mv88e6xxx_setup_port()
doesn't need that. It just needs to look at the mac_capabilities bitmap.

                                       and other phy_devices are released
  // similarly, the remove process also has the same problem

The root cause is traced to the phy_device is not disconnected when
removes one r6040 device in r6040_remove_one() or on error handling path
after r6040_mii probed successfully. In r6040_mii_probe(), a net ethernet
device is connected to the first PHY device of mii_bus, in order to
notify the connected driver when the link status changes, which is the
default behavior of the PHY infrastructure to handle everything.
Therefore the phy_device should be disconnected when removes one r6040
device or on error handling path.

Fix it by adding phy_disconnect() when removes one r6040 device or on
error handling path after r6040_mii probed successfully.

unix: Fix race in SOCK_SEQPACKET's unix_dgram_sendmsg()

There is a race resulting in alive SOCK_SEQPACKET socket
may change its state from TCP_ESTABLISHED to TCP_CLOSE:

unix_release_sock(peer)                  unix_dgram_sendmsg(sk)
  sock_orphan(peer)
    sock_set_flag(peer, SOCK_DEAD)
                                           sock_alloc_send_pskb()
                                             if !(sk->sk_shutdown & SEND_SHUTDOWN)
                                               OK
                                           if sock_flag(peer, SOCK_DEAD)
                                             sk->sk_state = TCP_CLOSE
  sk->sk_shutdown = SHUTDOWN_MASK

After that socket sk remains almost normal: it is able to connect, listen, accept
and recvmsg, while it can't sendmsg.

Since this is the only possibility for alive SOCK_SEQPACKET to change
the state in such way, we should better fix this strange and potentially
danger corner case.

Note, that we will return EPIPE here like this is normally done in sock_alloc_send_pskb().
Originally used ECONNREFUSED looks strange, since it's strange to return
a specific retval in dependence of race in kernel, when user can't affect on this.

Also, move TCP_CLOSE assignment for SOCK_DGRAM sockets under state lock
to fix race with unix_dgram_connect():

unix_dgram_connect(other)            unix_dgram_sendmsg(sk)
                                       unix_peer(sk) = NULL
                                       unix_state_unlock(sk)
  unix_state_double_lock(sk, other)
  sk->sk_state  = TCP_ESTABLISHED
  unix_peer(sk) = other
  unix_state_double_unlock(sk, other)
                                       sk->sk_state  = TCP_CLOSED

This patch fixes both of these races.

bpf: Resolve fext program type when checking map compatibility

The bpf_prog_map_compatible() check makes sure that BPF program types are
not mixed inside BPF map types that can contain programs (tail call maps,
cpumaps and devmaps). It does this by setting the fields of the map->owner
struct to the values of the first program being checked against, and
rejecting any subsequent programs if the values don't match.

One of the values being set in the map owner struct is the program type,
and since the code did not resolve the prog type for fext programs, the map
owner type would be set to PROG_TYPE_EXT and subsequent loading of programs
of the target type into the map would fail.

This bug is seen in particular for XDP programs that are loaded as
PROG_TYPE_EXT using libxdp; these cannot insert programs into devmaps and
cpumaps because the check fails as described above.

Fix the bug by resolving the fext program type to its target program type
as elsewhere in the verifier.

net: enetc: avoid buffer leaks on xdp_do_redirect() failure

Before enetc_clean_rx_ring_xdp() calls xdp_do_redirect(), each software
BD in the RX ring between index orig_i and i can have one of 2 refcount
values on its page.

We are the owner of the current buffer that is being processed, so the
refcount will be at least 1.

If the current owner of the buffer at the diametrically opposed index
in the RX ring (i.o.w, the other half of this page) has not yet called
kfree(), this page's refcount could even be 2.

enetc_page_reusable() in enetc_flip_rx_buff() tests for the page
refcount against 1, and [ if it's 2 ] does not attempt to reuse it.

But if enetc_flip_rx_buff() is put after the xdp_do_redirect() call,
the page refcount can have one of 3 values. It can also be 0, if there
is no owner of the other page half, and xdp_do_redirect() for this
buffer ran so far that it triggered a flush of the devmap/cpumap bulk
queue, and the consumers of those bulk queues also freed the buffer,
all by the time xdp_do_redirect() returns the execution back to enetc.

This is the reason why enetc_flip_rx_buff() is called before
xdp_do_redirect(), but there is a big flaw with that reasoning:
enetc_flip_rx_buff() will set rx_swbd->page = NULL on both sides of the
enetc_page_reusable() branch, and if xdp_do_redirect() returns an error,
we call enetc_xdp_free(), which does not deal gracefully with that.

In fact, what happens is quite special. The page refcounts start as 1.
enetc_flip_rx_buff() figures they're reusable, transfers these
rx_swbd->page pointers to a different rx_swbd in enetc_reuse_page(), and
bumps the refcount to 2. When xdp_do_redirect() later returns an error,
we call the no-op enetc_xdp_free(), but we still haven't lost the
reference to that page. A copy of it is still at rx_ring->next_to_alloc,
but that has refcount 2 (and there are no concurrent owners of it in
flight, to drop the refcount). What really kills the system is when
we'll flip the rx_swbd->page the second time around. With an updated
refcount of 2, the page will not be reusable and we'll really leak it.
Then enetc_new_page() will have to allocate more pages, which will then
eventually leak again on further errors from xdp_do_redirect().

The problem, summarized, is that we zeroize rx_swbd->page before we're
completely done with it, and this makes it impossible for the error path
to do something with it.

Since the packet is potentially multi-buffer and therefore the
rx_swbd->page is potentially an array, manual passing of the old
pointers between enetc_flip_rx_buff() and enetc_xdp_free() is a bit
difficult.

For the sake of going with a simple solution, we accept the possibility
of racing with xdp_do_redirect(), and we move the flip procedure to
execute only on the redirect success path. By racing, I mean that the
page may be deemed as not reusable by enetc (having a refcount of 0),
but there will be no leak in that case, either.

Once we accept that, we have something better to do with buffers on
XDP_REDIRECT failure. Since we haven't performed half-page flipping yet,
we won't, either (and this way, we can avoid enetc_xdp_free()
completely, which gives the entire page to the slab allocator).
Instead, we'll call enetc_xdp_drop(), which will recycle this half of
the buffer back to the RX ring.

bpf: Synchronize dispatcher update with bpf_dispatcher_xdp_func

Hao Sun reported crash in dispatcher image [1].

Currently we don't have any sync between bpf_dispatcher_update and
bpf_dispatcher_xdp_func, so following race is possible:

cpu 0:                               cpu 1:

bpf_prog_run_xdp
   ...
   bpf_dispatcher_xdp_func
     in image at offset 0x0

                                      bpf_dispatcher_update
                                        update image at offset 0x800
                                      bpf_dispatcher_update
                                        update image at offset 0x0

     in image at offset 0x0 -> crash

Fixing this by synchronizing dispatcher image update (which is done
in bpf_dispatcher_update function) with bpf_dispatcher_xdp_func that
reads and execute the dispatcher image.

Calling synchronize_rcu after updating and installing new image ensures
that readers leave old image before it's changed in the next dispatcher
update. The update itself is locked with dispatcher's mutex.

The bpf_prog_run_xdp is called under local_bh_disable and synchronize_rcu
will wait for it to leave [2].

but in our validation to make sure the prog is meant to be attached to
BPF_LSM_CGROUP, we return too early if the check fails. This results in
lack of decrementing prog's refcnt (through bpf_prog_put)
leaving the LSM program alive past the point of the expected lifecycle.
This fix allows for the decrement to take place.

mISDN: hfcsusb: don't call dev_kfree_skb/kfree_skb() under spin_lock_irqsave()

It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.

It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead.
The difference between them is free reason, dev_kfree_skb_irq() means
the SKB is dropped in error and dev_consume_skb_irq() means the SKB
is consumed in normal.

skb_queue_purge() is called under spin_lock_irqsave() in hfcusb_l2l1D(),

to move the dch->squeue to a free queue, also enqueue the tx_skb and

In tx_iso_complete(), dev_kfree_skb() is called to consume the transmitted
SKB, so replace it with dev_consume_skb_irq().

Bonding: fix high prio not effect issue

When a high prio link up, if there has current link, it will not do
failover as we missed the check in link up event. Fix it in this patchset

bonding: do failover when high prio link up

Currently, when a high prio link enslaved, or when current link down,
the high prio port could be selected. But when high prio link up, the
new active slave reselection is not triggered. Fix it by checking link's
prio when getting up. Making the do_failover after looping all slaves as
there may be multi high prio slaves up.

  distro and bootloader folks (GRUB, systemd-boot), where the main focus
  has been on removing pointless per-arch differences in the way EFI
  boots a Linux kernel.

   - Refactor the zboot code so that it incorporates all the EFI stub
     logic, rather than calling the decompressed kernel as a EFI app.

   - Add support for initrd= command line option to x86 mixed mode.

   - Allow initrd= to be used with arbitrary EFI accessible file systems
     instead of just the one the kernel itself was loaded from.

   - Move some x86-only handling and manipulation of the EFI memory map
     into arch/x86, as it is not used anywhere else.

   - More flexible handling of any random seeds provided by the boot
     environment (i.e., systemd-boot) so that it becomes available much
     earlier during the boot.

   - Allow improved arch-agnostic EFI support in loaders, by setting a
     uniform baseline of supported features, and adding a generic magic
     number to the DOS/PE header. This should allow loaders such as GRUB
     or systemd-boot to reduce the amount of arch-specific handling
     substantially.

   - (arm64) Run EFI runtime services from a dedicated stack, and use it
     to recover from synchronous exceptions that might occur in the
     firmware code.

   - (arm64) Ensure that we don't allocate memory outside of the 48-bit
     addressable physical range.

   - Make EFI pstore record size configurable

   - Add support for decoding CXL specific CPER records"

"Tux gets for xmas an improvement to the average lookup performance of
  kallsyms_lookup_name() by 715x thanks to the work by Zhen Lei, which
  upgraded our old implementation from being O(n) to O(log(n)), while
  also retaining the old implementation support on /proc/kallsyms.

  The only penalty was increasing the memory footprint by 3 *
  kallsyms_num_syms. Folks who want to improve this further now also
  have a dedicated selftest facility through KALLSYMS_SELFTEST.

  Stephen Boyd added zstd in-kernel decompression support, but the only
  users of this would be folks using the load-pin LSM because otherwise
  we do module decompression in userspace.

  The only other thing with mentioning is a minor boot time optimization
  by Rasmus Villemoes which deferes param_sysfs_init() to late init. The
  rest is cleanups and minor fixes"

Merge tag 'clk-for-linus' of git://git./linux/kernel/git/clk/linux

Pull clk driver updates from Stephen Boyd:
"A pile of clk driver updates with a small tracepoint patch to the clk
  core this time around.

  The core framework is effectively unchanged, with the majority of the
  diff going to the Qualcomm clk driver directory because they added two
  3k line files that are almost all clk data (Abel Vesa from Linaro
  tried to shrink the number of lines down, but it doesn't seem to be
  possible without sacrificing readability).

  The second big driver this time around is the Rockchip rk3588 clk and
  reset unit, at _only_ 2.5k lines.

  Ignoring the big clk drivers from the familiar SoC vendors, there's
  just a bunch of little clk driver updates and fixes throughout here.

  It's the usual set of clk data fixups to describe proper parents, or
  add frequencies to frequency tables, or plug memory leaks when
  function calls fail. Also, some drivers are converted to use modern
  clk_hw APIs, which is always nice to see. And data is deduplicated,
  leading to a smaller kernel Image.

  Overall this batch has a larger collection of cleanups than it
  typically does. Maybe that means there are less new SoCs right now
  that need supporting, and the focus has shifted to quality and
  reliability. I can dream.

  New Drivers:
   - Frequency hopping controller hardware on MediaTek MT8186
   - Global clock controller for Qualcomm SM8550
   - Display clock controller for Qualcomm SC8280XP
   - RPMh clock controller for Qualcomm QDU1000 and QRU1000 SoCs
   - CPU PLL on MStar/SigmaStar SoCs
   - Support for the clock and reset unit of the Rockchip rk3588

  Updates:
   - Tracepoints for clk_rate_request structures
   - Debugfs support for fractional divider clk
   - Make MxL's CGU driver secure compatible
   - Ingenic JZ4755 SoC clk support
   - Support audio clks on X1000 SoCs
   - Remove flags from univ/main/syspll child fixed factor clocks across
     MediaTek platforms
   - Fix clock dependency for ADC on MediaTek MT7986
   - Fix parent for FlexSPI clock for i.MX93
   - Add USB suspend clock on i.MX8MP
   - Unmap anatop base on error for i.MX93 driver
   - Change enet clock parent to wakeup_axi_root for i.MX93
   - Drop LPIT1, LPIT2, TPM1 and TPM3 clocks for i.MX93
   - Mark HSIO bus clock and SYS_CNT clock as critical on i.MX93
   - Add 320MHz and 640MHz entries to PLL146x
   - Add audio shared gate and SAI clocks for i.MX8MP
   - Fix a possible memory leak in the error path of rockchip PLL
     creation
   - Fix header guard for V3S clocks

Merge tag 'pinctrl-v6.2-1' of git://git./linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
"The two large chunks is the header clean-up from Andy and the Qualcomm
  DT bindings clean-up from Krzysztof. Each which could give rise to
  conflicts, but I haven't seen any.

  The YAML conversions happening around the device tree is the biggest
  item in the series and is the result of Rob Herrings ambition to
  autovalidate these trees against strict schemas and it is paying off
  in lots of bugs found and ever prettier device trees. Sooner or later
  the transition will be complete, Krzysztof is fixing up all of the
  Qualcomm stuff, which is pretty voluminous.

  Core changes:

   - minor but nice and important documentation clean-ups

  New drivers:

   - subdriver for the Qualcomm SDM670 SoC

   - subdriver for the Intel Moorefield SoC

   - trivial support for the NXP Freescale i.MXRT1170 SoC

  Other changes and improvements

   - major clean-up of the Qualcomm pin control device tree bindings by
     Krzysztof

   - major header clean-up by Andy

   - some immutable irqchip clean-up for the Actions Semiconductor and
     Nuvoton drivers

   - GPIO helpers for The Cypress cy8c95x0 driver

   - bias handling in the Mediatek MT7986 driver

   - remove the unused pins-are-numbered concept that never flew"

Merge tag 'spi-v6.2' of git://git./linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
"A busy enough release, but not for the core which has only seen very
  small updates. The biggest addition is the readdition of support for
  detailed configuration of the timings around chip selects. That had
  been removed for lack of use but there's been applications found for
  it on Atmel systems. Otherwise the updates are mostly feature
  additions and cleanups to existing drivers.

  Summary:

   - Provide a helper for getting device match data in a way that
     abstracts away which firmware interface is being used.

   - Re-add the spi_set_cs_timing() API for detailed configuration of
     the timing around chip select and support it on Atmel.

Merge tag 'regulator-v6.2' of git://git./linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
"Quite a quiet release for regulator, the diffstat is dominated by the
  I2C migration to probe_new() and the newly added MT6357 driver. We've
  just one framework addition and the rest is all new device support,
  fixes and cleanups.

  The framework addition is an API for requesting all regulators defined
  in DT, this isn't great practice but has reasonable applications when
  there is generic code handling devices on buses where the bus
  specification doesn't include power. The immediate application is MDIO
  but I believe there's others, it's another API that'll need an eye
  keeping on it for undesirable usage.

  Summary:

    - An API for requesting all regulators defined in DT

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is

Pull sound updates from Takashi Iwai:
"This looks like a relatively calm development cycle; there have been
  only few changes in ALSA and ASoC core sides while we get lots of
  device-specific fixes and updates as usual. Most of commits are about
  ASoC, including Intel SOF/AVS and many device tree updates.

  Below are some highlights:

  Core:
   - Improvement in memalloc helper for fallback allocations
   - More cleanups of ASoC DAPM code

  ASoC:
   - Factoring out of mapping hw_params onto SoundWire configuration
   - The ever ongoing overhauls of the Intel DSP code continue,
     including support for loading libraries and probes with IPC4 on
     SOF.
   - Support for more sample formats on JZ4740
   - Lots of device tree conversions and fixups
   - Support for Allwinner D1, a range of AMD and Intel systems,
     Mediatek systems with multiple DMICs, Nuvoton NAU8318, NXP
     fsl_rpmsg and i.MX93, Qualcomm AudioReach Enable, MFC and SAL,
     RealTek RT1318 and Rockchip RK3588

  ALSA:
   - Addition of PCM kselftest; still minimalistic but can be extended
     in future
   - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
   - Usual device-specific quirk updates for USB- and HD-audio
   - FireWire DICE updates

  This also contains a few cross-tree updates:
