Checking the SOCK_WIFI_STATUS flag bit in sk_flags may give wrong results
since sk_flags are part of a union and the union is used otherwise. Add
sk_requests_wifi_status() which checks if sk is non-NULL, sk is a full
socket (so flags are valid) and checks the flag bit.
Fixes: 76a853f86c ("wifi: free SKBTX_WIFI_STATUS skb tx_flags flag")

As per IEEE 802.11be-2024 - 9.4.2.321, EHT operation element
contains MCS15 Disable subfield as the sixth bit, which is set when
MCS15 support is not enabled.
Get MCS15 support from EHT operation params and add it in link_conf
so that driver can use this value to know if EHT-MCS 15 reception
is enabled.

Older drivers and drivers with lower queue counts often have a static
array of queues, rather than allocating structs for each queue on demand.
Add a helper for adding up qstats from a queue range. Expectation is
that driver will pass a queue range [netdev->real_num_*x_queues, MAX).
It was tempting to always use num_*x_queues as the end, but virtio
seems to clamp its queue count after allocating the netdev. And this
way we can trivaly reuse the helper for [0, real_..).

Accidentally spotted while trying to understand what else needs
to be renamed to netif_ prefix. Most of the calls to dev_set_promiscuity
are adjacent to dev_set_allmulti or dev_disable_lro so it should
be safe to add the lock. Note that new netif_set_promiscuity is
currently unused, the locked paths call __dev_set_promiscuity directly.

Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.
To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.
Also, this allows to possibly carry types that are unrelated to NLA_*
values.

from Jordan Rife.
2) Fixed a crash when a bpf qdisc is set in
the net.core.default_qdisc, from Amery Hung.
3) A few other fixes in the bpf qdisc, from Amery Hung.
- Always call qdisc_watchdog_init() in the .init prologue such that
the .reset/.destroy epilogue can always call qdisc_watchdog_cancel()
without issue.
- bpf_qdisc_init_prologue() was incorrectly returning an error
when the bpf qdisc is set as the default_qdisc and the mq is creating
the default_qdisc. It is now fixed.

Require that iter->batch always contains a full bucket snapshot. This
invariant is important to avoid skipping or repeating sockets during
iteration when combined with the next few patches. Before, there were
two cases where a call to bpf_iter_udp_batch may only capture part of a
bucket:
1. When bpf_iter_udp_realloc_batch() returns -ENOMEM [1].
2. When more sockets are added to the bucket while calling
bpf_iter_udp_realloc_batch(), making the updated batch size
insufficient [2].
In cases where the batch size only covers part of a bucket, it is
possible to forget which sockets were already visited, especially if we
have to process a bucket in more than two batches. This forces us to
choose between repeating or skipping sockets, so don't allow this:
1. Stop iteration and propagate -ENOMEM up to userspace if reallocation
fails instead of continuing with a partial batch.
2. Try bpf_iter_udp_realloc_batch() with GFP_USER just as before, but if
we still aren't able to capture the full bucket, call
bpf_iter_udp_realloc_batch() again while holding the bucket lock to
guarantee the bucket does not change. On the second attempt use
GFP_NOWAIT since we hold onto the spin lock.
Introduce the udp_portaddr_for_each_entry_from macro and use it instead
of udp_portaddr_for_each_entry to make it possible to continue iteration
from an arbitrary socket. This is required for this patch in the
GFP_NOWAIT case to allow us to fill the rest of a batch starting from
the middle of a bucket and the later patch which skips sockets that were
already seen.
Testing all scenarios directly is a bit difficult, but I did some manual
testing to exercise the code paths where GFP_NOWAIT is used and where
ERR_PTR(err) is returned. I used the realloc test case included later
in this series to trigger a scenario where a realloc happens inside
bpf_iter_udp_batch and made a small code tweak to force the first
realloc attempt to allocate a too-small batch, thus requiring
another attempt with GFP_NOWAIT. Some printks showed both reallocs with
the tests passing:
Apr 25 23:16:24 crow kernel: go again GFP_USER
Apr 25 23:16:24 crow kernel: go again GFP_NOWAIT
With this setup, I also forced each of the bpf_iter_udp_realloc_batch
calls to return -ENOMEM to ensure that iteration ends and that the
read() in userspace fails.

After 52358dd63e ("net: phy: remove function stubs") there's a
problem if CONFIG_MDIO_BUS is set, but CONFIG_PHYLIB is not.
mdiobus_scan() uses phylib functions like get_phy_device().
Bringing back the stub wouldn't make much sense, because it would
allow to compile mdiobus_scan(), but the function would be unusable.
The stub returned NULL, and we have the following in mdiobus_scan():
phydev = get_phy_device(bus, addr, c45);
if (IS_ERR(phydev))
return phydev;
So calling mdiobus_scan() w/o CONFIG_PHYLIB would cause a crash later in
mdiobus_scan(). In general the PHYLIB functionality isn't optional here.
Consequently, MDIO bus providers depend on PHYLIB.
Therefore factor it out and build it together with the libphy core
modules. In addition make all MDIO bus providers under /drivers/net/mdio
depend on PHYLIB. Same applies to enetc MDIO bus provider. Note that
PHYLIB selects MDIO_DEVRES, therefore we can omit this here.

Both CS35L56 and CS42L43 have maximum volumes above 0dB.
However, for many use cases, this can cause distorted audio, depending

for example if the audio passes through a gain control before reaching
the amp or the signal path has been tuned for a particular maximum

In the cases where systems use the soc_sdw_* drivers, audio above the

The volume control for cs35l56 speakers has a maximum gain of +12 dB.
However, for many use cases, this can cause distorted audio, depending
various factors, such as other signal-processing elements in the chain,
for example if the audio passes through a gain control before reaching
the amp or the signal path has been tuned for a particular maximum
gain in the amp.
In the case of systems which use the soc_sdw_* driver, audio will
likely be distorted in all cases above 0 dB, therefore add a volume
limit of 400, which is 0 dB maximum volume inside this driver.
The volume limit should be applied to both soundwire and soundwire
bridge configurations.

Load balance new TCP connections across nexthops also when they
connect to the same service at a single remote address and port.
This affects only port-based multipath hashing:
fib_multipath_hash_policy 1 or 3.
Local connections must choose both a source address and port when
connecting to a remote service, in ip_route_connect. This
"chicken-and-egg problem" (commit 2d7192d6cb ("ipv4: Sanitize and
simplify ip_route_{connect,newports}()")) is resolved by first
selecting a source address, by looking up a route using the zero
wildcard source port and address.
As a result multiple connections to the same destination address and
port have no entropy in fib_multipath_hash.
This is not a problem when forwarding, as skb-based hashing has a
4-tuple. Nor when establishing UDP connections, as autobind there
selects a port before reaching ip_route_connect.
Load balance also TCP, by using a random port in fib_multipath_hash.
Port assignment in inet_hash_connect is not atomic with
ip_route_connect. Thus ports are unpredictable, effectively random.
Implementation details:
Do not actually pass a random fl4_sport, as that affects not only
hashing, but routing more broadly, and can match a source port based
policy route, which existing wildcard port 0 will not. Instead,
define a new wildcard flowi flag that is used only for hashing.
Selecting a random source is equivalent to just selecting a random
hash entirely. But for code clarity, follow the normal 4-tuple hash
process and only update this field.
fib_multipath_hash can be reached with zero sport from other code
paths, so explicitly pass this flowi flag, rather than trying to infer
this case in the function itself.

With multipath routes, try to ensure that packets leave on the device
that is associated with the source address.
Avoid the following tcpdump example:
veth0 Out IP 10.1.0.2.38640 > 10.2.0.3.8000: Flags [S]
veth1 Out IP 10.1.0.2.38648 > 10.2.0.3.8000: Flags [S]
Which can happen easily with the most straightforward setup:
ip addr add 10.0.0.1/24 dev veth0
ip addr add 10.1.0.1/24 dev veth1
ip route add 10.2.0.3 nexthop via 10.0.0.2 dev veth0 \
nexthop via 10.1.0.2 dev veth1
This is apparently considered WAI, based on the comment in
ip_route_output_key_hash_rcu:
* 2. Moreover, we are allowed to send packets with saddr
* of another iface. --ANK
It may be ok for some uses of multipath, but not all. For instance,
when using two ISPs, a router may drop packets with unknown source.
The behavior occurs because tcp_v4_connect makes three route
lookups when establishing a connection:
1. ip_route_connect calls to select a source address, with saddr zero.
2. ip_route_connect calls again now that saddr and daddr are known.
3. ip_route_newports calls again after a source port is also chosen.
With a route with multiple nexthops, each lookup may make a different
choice depending on available entropy to fib_select_multipath. So it
is possible for 1 to select the saddr from the first entry, but 3 to
select the second entry. Leading to the above situation.
Address this by preferring a match that matches the flowi4 saddr. This
will make 2 and 3 make the same choice as 1. Continue to update the
backup choice until a choice that matches saddr is found.
Do this in fib_select_multipath itself, rather than passing an fl4_oif
constraint, to avoid changing non-multipath route selection. Commit
e6b45241c5 ("ipv4: reset flowi parameters on route connect") shows
how that may cause regressions.
Also read ipv4.sysctl_fib_multipath_use_neigh only once. No need to
refresh in the loop.
This does not happen in IPv6, which performs only one lookup.

The conversion function from MIDI 1.0 to UMP packet contains an
internal buffer to keep the incoming MIDI bytes, and its size is 4, as
it was supposed to be the max size for a MIDI1 UMP packet data.
However, the implementation overlooked that SysEx is handled in a
different format, and it can be up to 6 bytes, as found in
do_convert_to_ump(). It leads eventually to a buffer overflow, and
may corrupt the memory when a longer SysEx message is received.
The fix is simply to extend the buffer size to 6 to fit with the SysEx
UMP message.

The phy-upstream enum is already defined in the ethtool.h UAPI header
and used by the ethtool userspace tool. However, the ethtool spec does
not reference it, causing YNL to auto-generate a duplicate and redundant
enum.
Fix this by updating the spec to reference the existing UAPI enum
in ethtool.h.

The "noqueue" qdisc can either be directly attached, or get default
attached if net_device priv_flags has IFF_NO_QUEUE. In both cases, the
allocated Qdisc structure gets it's enqueue function pointer reset to
NULL by noqueue_init() via noqueue_qdisc_ops.
This is a common case for software virtual net_devices. For these devices
with no-queue, the transmission path in __dev_queue_xmit() will bypass
the qdisc layer. Directly invoking device drivers ndo_start_xmit (via
dev_hard_start_xmit). In this mode the device driver is not allowed to
ask for packets to be queued (either via returning NETDEV_TX_BUSY or
stopping the TXQ).
The simplest and most reliable way to identify this no-queue case is by
checking if enqueue == NULL.
The vrf driver currently open-codes this check (!qdisc->enqueue). While
functionally correct, this low-level detail is better encapsulated in a
dedicated helper for clarity and long-term maintainability.
To make this behavior more explicit and reusable, this patch introduce a
new helper: qdisc_txq_has_no_queue(). Helper will also be used by the
veth driver in the next patch, which introduces optional qdisc-based
backpressure.
This is a non-functional change.

Commit 7491cdf46b ("cpufreq: Avoid using inconsistent policy->min and
policy->max") overlooked the fact that policy->min and policy->max were
accessed directly in cpufreq_frequency_table_target() and in the
functions called by it. Consequently, the changes made by that commit
led to problems with setting policy limits.
Address this by passing the target frequency limits to __resolve_freq()
and cpufreq_frequency_table_target() and propagating them to the
functions called by the latter.

Pull vfs fixes from Christian Brauner:
- For some reason we went from zero to three maintainers for HFS/HFS+
in a matter of days. The lesson to learn from this might just be that
we need to threaten code removal more often!?
- Fix a regression introduced by enabling large folios for lage logical
block sizes. This has caused issues for noref migration with large
folios due to sleeping while in an atomic context.
New sleeping variants of pagecache lookup helpers are introduced.
These helpers take the folio lock instead of the mapping's private
spinlock. The problematic users are converted to the sleeping
variants and serialize against noref migration. Atomic users will
bail on seeing the new BH_Migrate flag.
This also shrinks the critical region of the mapping's private lock
and the new blocking callers reduce contention on the spinlock for
bdev mappings.
- Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
first bug is using a mountpoint that is located on a mount we're not
holding a reference to. The second bug is putting the mountpoint
after we've called namespace_unlock() as it's no longer guaranteed
that it does stay a mountpoint.
- Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
just to query i_mode instead of simply querying the inode directly.
This also avoids lifetime issues for the dm code by an earlier bugfix
this cycle that moved bdev_statx() handling into vfs_getattr_nosec().
- Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
- Fix a performance regression for files when multiple callers issue a
close when it's not the last reference.
- Remove a duplicate noinline annotation from pipe_clear_nowait().

hopefully this is finally resolved
- MAINTAINERS file update, documenting that the driver-core tree is
now under a "shared" maintainership model, thanks to Rafael and
Danilo for offering to do this!
- auxbus documentation and MAINTAINERS file update
- MAINTAINERS file update for Rust PCI code
- firmware rust binding fixup
- software node link fix
All of these have been in linux-next for over a week with no reported
issues.
