Pull networking updates from Jakub Kicinski:
"The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.

Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.

Core & protocols:

- Support Device Memory TCP, ability to zero-copy receive TCP
payloads to a DMABUF region of memory while packet headers land
separately in normal kernel buffers, and TCP processes then as
usual.

- The ability to read the PTP PHC (Physical Hardware Clock) alongside
MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
only CLOCK_REALTIME was supported.

- Allow matching on all bits of IP DSCP for routing decisions.
Previously we only supported on matching TOS bits in IPv4 which is
a narrower interpretation of the same header field.

- Increase the range of weights used for multi-path routing from
8 bits to 16 bits.

- Add support for IPv6 PIO p flag in the Prefix Information Option
per draft-ietf-6man-pio-pflag.

- IPv6 IOAM6 support for new tunsrc encap mode for better
performance.

- Detect destinations which blackhole MPTCP traffic and avoid
initiating MPTCP connections to them for a certain period of time,
1h by default.

- Improve IPsec control path performance by removing the inexact
policies list.

- AF_VSOCK: add support for SIOCOUTQ ioctl.

- Add enum for reasons TCP reset was sent for easier tracing.

- Add SMC ringbufs usage statistics.

Drivers:

- Handle netconsole setup failures more gracefully, don't fail
loading, retain the specified target as disabled.

- Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

Filtering:

- Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
when long-lived sockets miss a chance to set additional callbacks
if a sockops program was not attached early in their lifetime.

- Support using BPF skb helpers in tracepoints.

- Conntrack Netlink: support CTA_FILTER for flush.

- Improve SCTP support in nfnetlink_queue.

- Improve performance of large nftables flush transactions.

Things we sprinkled into general kernel code:

- selftests: support setting an "interpreter" for script files; make
it easy to run as separate cases tests where one "interpreter" is
fed various test descriptions (in our case packet sequences).

Driver API:

- Extend core and ethtool APIs to support many PHYs connected to a
single interface (PHY topologies).

- Extend cable diagnostics to specify whether Time Domain
Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
used.

- Add library for implementing MAC-PHY Ethernet drivers for SPI
devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
Interface (TC6) standard.

- Add helpers to the PHY framework, for PHYs following the Open
Alliance standards:
- 1000BaseT1 link settings
- cable test and diagnostics

- Support listing / dumping all allocated RSS contexts.

- Add configuration for frequency Embedded SYNC in DPLL, which
magically embeds sync pulses into Ethernet signaling.

====================
Intel Wired LAN Driver Updates 2024-08-26 (ice)

This series contains updates to ice driver only.

Jake implements and uses rd32_poll_timeout to replace a jiffies loop for
calling ice_sq_done. The rd32_poll_timeout() function is designed to allow
simplifying other places in the driver where we need to read a register
until it matches a known value.

Jake, Bruce, and Przemek update ice_debug_cq() to be more robust, and more
useful for tracing control queue messages sent and received by the device
driver.

Jake rewords several commands in the ice_control.c file which previously
referred to the "Admin queue" when they were actually generic functions
usable on any control queue.

Jake removes the unused and unnecessary cmd_buf array allocation for send
queues. This logic originally was going to be useful if we ever implemented
asynchronous completion of transmit messages. This support is unlikely to
materialize, so the overhead of allocating a command buffer is unnecessary.

Sergey improves the log messages when the ice driver reports that the NVM
version on the device is not supported by the driver. Now, these messages
include both the discovered NVM version and the requested/expected NVM
version.

Aleksandr Mishin corrects overallocation of memory related to adding
scheduler nodes.

ice: remove unnecessary control queue cmd_buf arrays

ice: stop intermixing AQ commands/responses debug dumps

ice: stop intermixing AQ commands/responses debug dumps

The ice_debug_cq() function is called to generate a debug log of control
queue messages both sent and received. It currently does this over a
potential total of 6 different printk invocations.

The main logic prints over 4 calls to ice_debug():

1. The metadata including opcode, flags, datalength and return value.
2. The cookie in the descriptor.
3. The parameter values.
4. The address for the databuffer.

In addition, if the descriptor has a data buffer, it can be logged with two
additional prints:

5. A message indicating the start of the data buffer.
6. The actual data buffer, printed using print_hex_dump_debug.

This can lead to trouble in the event that two different PFs are logging
messages. The messages become intermixed and it may not be possible to
determine which part of the output belongs to which control queue message.

To fix this, it needs to be possible to unambiguously determine which
messages belong together. This is trivial for the messages that comprise
the main printing. Combine them together into a single invocation of
ice_debug().

The message containing a hex-dump of the data buffer is a bit more
complicated. This is printed separately as part of print_hex_dump_debug.
This function takes a prefix, which is currently always set to
KBUILD_MODNAME. Extend this prefix to include the buffer address for the
databuffer, which is printed as part of the main print, and which is
guaranteed to be unique for each buffer.

Refactor the ice_debug_array(), introducing an ice_debug_array_w_prefix().
Build the prefix by combining KBUILD_MODNAME with the databuffer address
using snprintf().

These changes make it possible to unambiguously determine what data belongs
to what control queue message.

ice: implement and use rd32_poll_timeout for ice_sq_done timeout

The ice_sq_done function is used to check the control queue head register
and determine whether or not the control queue processing is done. This
function is called in a loop checking against jiffies for a specified
timeout.

The pattern of reading a register in a loop until a condition is true or a
timeout is reached is a relatively common pattern. In fact, the kernel
provides a read_poll_timeout function implementing this behavior in
<linux/iopoll.h>

Use of read_poll_timeout is preferred over directly coding these loops.
However, using it in the ice driver is a bit more difficult because of the
rd32 wrapper. Implement a rd32_poll_timeout wrapper based on
read_poll_timeout.

Refactor ice_sq_done to use rd32_poll_timeout, replacing the loop calling
ice_sq_done in ice_sq_send_cmd. This simplifies the logic down to a single
ice_sq_done() call.

The implementation of rd32_poll_timeout uses microseconds for its timeout
value, so update the CQ timeout macros used to be specified in microseconds
units as well instead of using HZ for jiffies.

come with zero guarantees.

- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
is to support confidential VMs with deterministic private memory (SNP
and TDX) only in the TDP MMU.

- Fix a bug in a GUEST_MEMFD negative test that resulted in false passes

ASoC: Intel: avs: Fixes and new platforms support

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:

SKL <- APL <- CNL <- ICL <- TGL

rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.

Layout of the patchset:

First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.

Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.

The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.
