In order to support the multipeer architecture, upon connection setup
each side of a tunnel advertises a unique ID that the other side must
include in packets sent to them. Therefore when transmitting a packet, a
peer inserts the recipient's advertised ID for that specific tunnel into
the peer ID field. When receiving a packet, a peer expects to find its
own unique receive ID for that specific tunnel in the peer ID field.
Add support for the TX peer ID and embed it into transmitting packets.
If no TX peer ID is specified, fallback to using the same peer ID both
for RX and TX in order to be compatible with the non-multipeer compliant
peers.

Add the mphy reset property to the devicetree bindings for the Rockchip
RK3576 UFS host controller. The mphy reset signal is used to reset the
physical adapter. Resetting other components while leaving the mphy unreset
may occasionally prevent the UFS controller from successfully linking up
with the device.
This addresses an intermittent hardware bug where the UFS link fails to
establish under specific timing conditions with certain chips. While
difficult to reproduce initially, this issue was consistently observed in
downstream testing and requires explicit mphy reset control for full
stability.
Although this change increases the maxItems for resets and adds a new entry
(which technically alters the binding ABI), it does not break compatibility
for existing Linux systems. The driver uses
devm_reset_control_array_get_exclusive() to manage resets, allowing it to
function correctly with both older Device Trees (without the mphy entry)
and newer ones.

James Calligeros <jcalligeros99@gmail.com> says:
This series introduces some infrastructure to allow platform drivers
to specify what a DAI should be doing when it is not active on the
bus. The primary use case for this is configuring bus keepers which
may be integrated into various codecs. The instigating use case for
this functionality is an interesting bus topology on Apple Silicon
laptops with multiple codecs.
Most Apple Silicon laptops have six codecs split into groups of
three, driving a pair of dual opposed woofers and a tweeter for
L/R stereo sound. These codecs report the voltage and current across
their connected voice coils back to the SoC via the SDOUT pin,
represented as PCM data sent via configurable TDM slots. This data is
used in conjunction with the connected speaker's Thiele/Small Parameters
to ensure that the speaker is not being driven to levels that would
permanently damage them. This is integrated into CoreAudio on macOS.
speakersafetyd[1] handles this for Linux.
All of the codec SDOUT pins are attached to a single receiver port
on the SoC's I2S peripheral, however are split across two physical
data lines (one each for the left and right codec groups). The receiver
has an OR gate in front of it, which is used to sum the two lines.
If at any point a codec is trying to transmit data, and the "opposite"
line ends up floating high, the transmitting codec's data will be
corrupted. We need to guarantee that the idle line stays idle.
In the downstream Asahi Linux kernel[2], we set up one codec in each
group to zero-fill or pull down its line while a codec on the opposite
line is actively transmitting. This is done entirely in the codec
driver, however this approach is over-fit for this one use case. This
sort of functionality may also be of use for other hardware, so following
previous mailing list discussions[3], I have tried to expose the
functionality in a more configurable and generic way.
I have integrated this approach into our downstream platform driver
and select Devicetrees as an example of how this mechanism is intended
to be used[4].

Add properties to describe TDM slot idle behaviour. These properties can
be used to describe how a DAI is supposed to behave when not active.
For example, Apple Silicon laptops split a single I2S bus between two
physical lines which are combined at an OR gate in front of the
receiving port. One codec on each line is expected to transmit zeroes
during the active TDM slots of the opposite line, or we will have corrupted
data at the receiver.

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.
ARM:
- Correctly handle deactivation of interrupts that were activated
from LRs. Since EOIcount only denotes deactivation of interrupts
that are not present in an LR, start EOIcount deactivation walk
*after* the last irq that made it into an LR
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when pKVM
is already enabled -- not only thhis isn't possible (pKVM will
reject the call), but it is also useless: this can only happen for
a CPU that has already booted once, and the capability will not
change
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was
exposed by the recent conversion to kmalloc_obj(); rip out all the
ugliness that led to the wart
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR
access, float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in
kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked
as available whenever the kernel used scattered feature words for
them
- Validate _all_ GVAs, rather than just the first GVA, when
processing a range of GVAs for Hyper-V's TLB flush hypercalls
- Fix a brown paper bug in add_atomic_switch_msr()
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel
local APIC (and AVIC is enabled at the module level)
- Update CR8 write interception when AVIC is (de)activated, to fix a
bug where the guest can run in perpetuity with the CR8 intercept
enabled
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to
allow L1 hypervisors to set FREEZE_IN_SMM. This reverts (by
default) an unintentional tightening of userspace ABI in 6.17, and
provides some amount of backwards compatibility with hypervisors
who want to freeze PMCs on VM-Entry
- Validate the VMCS/VMCB on return to a nested guest from SMM,
because either userspace or the guest could stash invalid values in
memory and trigger the processor's consistency checks
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from
being unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite
being rather unintuitive
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd
selftest to 64 (from 8)"

By default, the Linux TCP implementation does not shrink the
advertised window (RFC 7323 calls this "window retraction") with the
following exceptions:
- When an incoming segment cannot be added due to the receive buffer
running out of memory. Since commit 8c670bdfa58e ("tcp: correct
handling of extreme memory squeeze") a zero window will be
advertised in this case. It turns out that reaching the required
memory pressure is easy when window scaling is in use. In the
simplest case, sending a sufficient number of segments smaller than
the scale factor to a receiver that does not read data is enough.
- Commit b650d953cd39 ("tcp: enforce receive buffer memory limits by
allowing the tcp window to shrink") addressed the "eating memory"
problem by introducing a sysctl knob that allows shrinking the
window before running out of memory.
However, RFC 7323 does not only state that shrinking the window is
necessary in some cases, it also formulates requirements for TCP
implementations when doing so (Section 2.4).
This commit addresses the receiver-side requirements: After retracting
the window, the peer may have a snd_nxt that lies within a previously
advertised window but is now beyond the retracted window. This means
that all incoming segments (including pure ACKs) will be rejected
until the application happens to read enough data to let the peer's
snd_nxt be in window again (which may be never).
To comply with RFC 7323, the receiver MUST honor any segment that
would have been in window for any ACK sent by the receiver and, when
window scaling is in effect, SHOULD track the maximum window sequence
number it has advertised. This patch tracks that maximum window
sequence number rcv_mwnd_seq throughout the connection and uses it in
tcp_sequence() when deciding whether a segment is acceptable.
rcv_mwnd_seq is updated together with rcv_wup and rcv_wnd in
tcp_select_window(). If we count tcp_sequence() as fast path, it is
read in the fast path. Therefore, rcv_mwnd_seq is put into rcv_wnd's
cacheline group.
The logic for handling received data in tcp_data_queue() is already
sufficient and does not need to be updated.
