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.
- 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

SFU since its (first) version 3.0 supports AF_LOCAL sockets and stores them
on filesytem as system file with one zero byte. Add support for detecting
this SFU socket type into cifs_sfu_type() function.
With this change cifs_sfu_type() would correctly detect all special file
types created by SFU: fifo, socket, symlink, block and char.

cifs: Put explicit zero byte into SFU block/char types
SFU types IntxCHR and IntxBLK are 8 bytes with zero as last byte. Make it
explicit in memcpy and memset calls, so the zero byte is visible in the
code (and not hidden as string trailing nul byte).
It is important for reader to show the last byte for block and char types
because it differs from the last byte of symlink type (which has it 0x01).
Also it is important to show that the type is not nul-term string, but
rather 8 bytes (with some printable bytes).

cifs: Add support for reading SFU symlink location
Currently when sfu mount option is specified then CIFS can recognize SFU
symlink, but is not able to read symlink target location. readlink()
syscall just returns that operation is not supported.
Implement this missing functionality in cifs_sfu_type() function. Read
target location of SFU-style symlink, parse it and fill into fattr's
cf_symlink_target member.
SFU-style symlink is file which has system attribute set and file content
is buffer "IntxLNK\1" (8th byte is 0x01) followed by the target location
encoded in little endian UCS-2/UTF-16. This format was introduced in
Interix 3.0 subsystem, as part of the Microsoft SFU 3.0 and is used also by
all later versions. Previous versions had no symlink support.

net: ethernet: fs_enet: Make the per clock optional
Some platforms that use fs_enet don't have the PER register clock. This

* SPI-NAND changes
The most impacting series this cycle is bringing support for continuous
reads in the SPI-NAND subsystem. This is a feature already merged in the
raw NAND subsystem which allows optimizing the internal fetch times in
the chip while reading sequential pages within an eraseblock. For now
only Macronix NANDs benefit from this feature. While we are talking
about Macronix, some of their chip need an explicit action for selecting
a different plane, and support for it has also been brought.
The bitflip threshold has also been set to the same arbitrary level as
in the raw NAND subsystem to optimize wear leveling decisions, and
finally support for a new Winbond chip has been added.
- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name. The
probe path tries to access the name without checking its existence
first. S28HS256T is the first flash to define its entry without a
name, uncovering this issue.
This caused a regression with the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM. After the commit, the
WB memory type is used without the IGNORE_PAT, resulting in the slower
UC memory type. In fact, UC is slow enough to basically cause guests
to not boot... but only on new processors such as Sapphire Rapids and
Cascade Lake. Coffee Lake for example works properly, though that might
also be an effect of being on a larger, more NUMA system.
The driver has been fixed but that does not help older guests. Until we
figure out whether Cascade Lake and newer processors are working as
intended, revert the commit. Long term we might add a quirk, but the
details depend on whether the processors are working as intended: for
example if they are, the quirk might reference bochs-compatible devices,
e.g. in the name and documentation, so that userspace can disable the
quirk by default and only leave it enabled if such a device is being
exposed to the guest.
If instead this is actually a bug in CLX+, then the actions we need to
take are different and depend on the actual cause of the bug.

Introduce HSR offload support for ICSSG
This series introduces HSR offload support for ICSSG driver. To support HSR
offload to hardware, ICSSG HSR firmware is used.
This series introduces,
1. HSR frame offload support for ICSSG driver.
2. HSR Tx Packet duplication offload
3. HSR Tx Tag and Rx Tag offload
4. Multicast filtering support in HSR offload mode.
5. Dependencies related to IEP.
HSR Test Setup:
--------------
___________ ___________ ___________
| | Link AB | | Link BC | |
__| AM64* |_________| AM64 |_________| AM64* |___
| | Station A | | Station B | | Station C | |
| |___________| |___________| |___________| |
| |
|______________________________________________________________|
Link CA
*Could be any device that supports two ethernet interfaces.
Steps to switch to HSR frame forward offload mode:
-------------------------------------------------
Example assuming eth1, eth2 ports of ICSSG1 on AM64-EVM
1) Enable HSR offload for both interfaces
ethtool -K eth1 hsr-fwd-offload on
ethtool -K eth1 hsr-dup-offload on
ethtool -K eth1 hsr-tag-ins-offload on
ethtool -K eth1 hsr-tag-rm-offload on
ethtool -K eth2 hsr-fwd-offload on
ethtool -K eth2 hsr-dup-offload on
ethtool -K eth2 hsr-tag-ins-offload on
ethtool -K eth2 hsr-tag-rm-offload on
2) Create HSR interface and add slave interfaces to it
ip link add name hsr0 type hsr slave1 eth1 slave2 eth2 \
supervision 45 version 1
3) Add IP address to the HSR interface
ip addr add <IP_ADDR>/24 dev hsr0
4) Bring up the HSR interface
ip link set hsr0 up
Switching back to previous mode:
--------------------------------
1) Delete HSR interface
ip link delete hsr0
2) Disable HSR port-to-port offloading mode, packet duplication
ethtool -K eth1 hsr-fwd-offload off
ethtool -K eth1 hsr-dup-offload off
ethtool -K eth1 hsr-tag-ins-offload off
ethtool -K eth1 hsr-tag-rm-offload off
ethtool -K eth2 hsr-fwd-offload off
ethtool -K eth2 hsr-dup-offload off
ethtool -K eth2 hsr-tag-ins-offload off
ethtool -K eth2 hsr-tag-rm-offload off
Testing the port-to-port frame forward offload feature:
-----------------------------------------------------
1) Connect the LAN cables as shown in the test setup.
2) Configure Station A and Station C in HSR non-offload mode.
3) Configure Station B is HSR offload mode.
4) Since HSR is a redundancy protocol, disconnect cable "Link CA",
to ensure frames from Station A reach Station C only through
Station B.
5) Run iperf3 Server on Station C and client on station A.
7) Check the CPU usage on Station B.
CPU usage report on Station B using mpstat when running UDP iperf3:

hsr tag insertion offload and hsr dup offload are tightly coupled in

will be stopped and ICSSG HSR firmwares will be loaded to them.
Similarly, when HSR interface is deleted, the PRU cores will be
restarted and the last used firmwares will be reloaded. PRUeth
interfaces will be back to the last used mode.
This commit also renames some APIs that are common between switch and
hsr mode with '_fw_offload' suffix.
The def_inc is stored in icss_iep structure. Currently default increment
(ns per clock tick) is hardcoded to 4 (Clock frequency being 250 MHz).
Change this to use the iep->def_inc variable as the iep structure is now
accessible to the driver files.
It seems the mlxbf-pmc driver is missing initializing sysfs attributes
which causes the warning below when CONFIG_LOCKDEP and
CONFIG_DEBUG_LOCK_ALLOC are enabled. This commit fixes it.

These sysfs attributes get registered by the device_add() respectively

use_cnt gets initialized to 0 and is incremented only after these calls.
So when power_supply_property_is_writeable() gets called it always return

When sending an oplock break request, opinfo->conn is used,
But freed ->conn can be used on multichannel.
This patch add a reference count to the ksmbd_conn struct
so that it can be freed when it is no longer used.

net: ethtool: phy: Don't set the context dev pointer for unfiltered DUMP
The context info allows continuing DUMP requests, shall they fill the
netlink buffer.
In the case of filtered DUMP requests, a reference on the netdev is
grabbed in the .start() callback and release in .done().
Unfiltered DUMP request don't need the dev pointer to be set in the context
info, doing so will trigger an unwanted netdev_put() in .done().

The first patch is by Uwe Kleine-König targets all CAN platform driver
and switches back the remove function to struct
platform_driver::remove().
A patch by Stefan Mätje fixes the help text of the ESD USB driver.
Jake Hamby's patch masks an unneeded interrupt in the m_can driver.
The last 2 patches target the rockchip_canfd driver. Arnd Bergmann's
patch reworks the delay calculation for the timekeeping worker, a
patch by me fixes the decoding of the error code register.

pull-request: can 2024-09-12
Kuniyuki Iwashima's patch fixes an incomplete bug fix in the CAN BCM
protocol, which was introduced during v6.11.
A patch by Stefan Mätje removes the unsupported CAN_CTRLMODE_3_SAMPLES
mode for CAN-USB/3-FD devices in the esd_usb driver.
The next patch is by Martin Jocic and enables 64-bit DMA addressing
for the kvaser_pciefd driver.
The last two patches both affect the m_can driver. Jake Hamby's patch
activates NAPI before interrupts are activated, a patch by me moves
the stopping of the clock after the device has been shut down.
