Core & protocols
----------------
- Replace busylock at the Tx queuing layer with a lockless list. Resulting
in a 300% (4x) improvement on heavy TX workloads, sending twice the
number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue. Normally we perform queue re-selection when flow comes out
of idle, but under extreme circumstances the flows may be constantly
busy. Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already did
for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly
quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for packets.
- Make MPTCP use Rx backlog processing. This lowers the lock pressure,
improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor fit
for modern container workloads, where limits are imposed using cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily
aggressive rcvbuf growth and overshot when the connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC 5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.
Driver API
----------
- Add CAN XL support to the CAN Netlink interface.
- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics,
as defined by the OPEN Alliance's "Advanced diagnostic features
for 100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads IPsec
and performs RSS.
- Add info to devlink params whether the current setting is the default
or a user override. Allow resetting back to default.
- Add standard device stats for PSP crypto offload.
- Leverage DSA frame broadcast to implement simple HSR frame duplication
for a lot of switches without dedicated HSR offload.
- Add uAPI defines for 1.6Tbps link modes.
Device drivers
--------------
- Add Motorcomm YT921x gigabit Ethernet switch support.
- Add MUCSE driver for N500/N210 1GbE NIC series.
- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.
- Add (and convert most drivers to) a dedicated ethtool callback
for reading the Rx ring count.
- Significant refactoring efforts in the STMMAC driver, which supports
Synopsys turn-key MAC IP integrated into a ton of SoCs.

i.MX95 USB2 inside HSIOMIX could still wakeup Linux, even if HSIOMIX
power domain(Digital logic) is off. There is still always on logic
have the wakeup capability which is out band wakeup capbility.
So use device_set_out_band_wakeup for i.MX95 to make sure usb2 could
wakeup system even if HSIOMIX power domain is in off state.

In the current implementation, usbnet uses a fixed tx_qlen of:
USB2: 60 * 1518 bytes = 91.08 KB
USB3: 60 * 5 * 1518 bytes = 454.80 KB
Such large transmit queues can be problematic, especially for cellular
modems. For example, with a typical celluar link speed of 10 Mbit/s, a
fully occupied USB3 transmit queue results in:
454.80 KB / (10 Mbit/s / 8 bit/byte) = 363.84 ms
of additional latency.
This patch adds support for Byte Queue Limits (BQL) [1] to dynamically
manage the transmit queue size and reduce latency without sacrificing
throughput.
Testing was performed on various devices using the usbnet driver for
packet transmission:
- DELOCK 66045: USB3 to 2.5 GbE adapter (ax88179_178a)
- DELOCK 61969: USB2 to 1 GbE adapter (asix)
- Quectel RM520: 5G modem (qmi_wwan)
- USB2 Android tethering (cdc_ncm)
No performance degradation was observed for iperf3 TCP or UDP traffic,
while latency for a prioritized ping application was significantly
reduced. For example, using the USB3 to 2.5 GbE adapter, which was fully
utilized by iperf3 UDP traffic, the prioritized ping was improved from
1.6 ms to 0.6 ms. With the same setup but with a 100 Mbit/s Ethernet
connection, the prioritized ping was improved from 35 ms to 5 ms.

A race condition during gadget teardown can lead to a use-after-free
in usb_gadget_state_work(), as reported by KASAN:
BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0
Workqueue: events usb_gadget_state_work
The fundamental race occurs because a concurrent event (e.g., an
interrupt) can call usb_gadget_set_state() and schedule gadget->work
at any time during the cleanup process in usb_del_gadget().
Commit 399a45e523 ("usb: gadget: core: flush gadget workqueue after
device removal") attempted to fix this by moving flush_work() to after
device_del(). However, this does not fully solve the race, as a new
work item can still be scheduled *after* flush_work() completes but
before the gadget's memory is freed, leading to the same use-after-free.
This patch fixes the race condition robustly by introducing a 'teardown'
flag and a 'state_lock' spinlock to the usb_gadget struct. The flag is
set during cleanup in usb_del_gadget() *before* calling flush_work() to
prevent any new work from being scheduled once cleanup has commenced.
The scheduling site, usb_gadget_set_state(), now checks this flag under
the lock before queueing the work, thus safely closing the race window.

Here is the big set of USB and thunderbolt drivers for 6.18-rc1. It was
another normal development cycle, with lots of the usual drivers getting
updates:
- Thunderbolt driver cleanups and additions
- dwc3 driver updates
- dwc2 driver updates
- typec driver updates
- xhci driver updates and additions
- offload USB engine updates for better power management
- unused tracepoint removals
- usb gadget fixes and updates as more users start to rely on these
drivers instead of the "old" function gadget drivers
- new USB device ids
- other minor driver USB driver updates
- new USB I/O driver framework and driver additions
The last item, the usb i/o driver, has an i2c and gpio driver added
through this tree. Those drivers were acked by the respective subsystem
maintainers, but you will get a merge conflict with the i2c tree where
new drivers were added in the same places in a Kconfig and Makefile.
The merge conflict is simple, just take both sides.
All of these have been in linux-next for a while, with the only issue
being the i2c tree merge conflicts.

Kuen-Han Tsai <khtsai@google.com> says:
This patch series refactors the error-handling paths in the bind()
function for f_ncm, f_acm, f_ecm, and f_rndis drivers.
The current, unified goto logic in these drivers is vulnerable to a null
pointer dereference. This is caused by the cleanup logic incorrectly
handling the stale usb_request pointer after a bind/unbind cycle. This
series fixes this issue by converting the drivers to use the modern
__free() scope-based cleanup mechanism.
Patches 1-2 are preparatory, adding the endpoint pointer to struct
usb_request and defining helpers for the __free() cleanup. The remaining
four patches use this new plumbing to refactor each driver.
Future work
-----------
1. Refactor usb_ep_free_request(), usb_ep_queue(), and usb_ep_dequeue()
functions as the ep parameter becomes redudant.
2. Convert the remaining gadget function drivers to use the new __free()
cleanup mechanism.

Gadget function drivers often have goto-based error handling in their
bind paths, which can be bug-prone. Refactoring these paths to use
__free() scope-based cleanup is desirable, but currently blocked.
The blocker is that usb_ep_free_request(ep, req) requires two
parameters, while the __free() mechanism can only pass a pointer to the
request itself.
Store an endpoint pointer in the struct usb_request. The pointer is
populated centrally in usb_ep_alloc_request() on every successful
allocation, making the request object self-contained.

Guan-Yu Lin <guanyulin@google.com> says:
Wesley Cheng and Mathias Nyman's USB offload design enables a
co-processor to handle some USB transfers, potentially allowing the
system to sleep (suspend-to-RAM) and save power. However, Linux's System
Sleep model halts the USB host controller when the main system isn't
managing any USB transfers. To address this, the proposal modifies the
system to recognize offloaded USB transfers and manage power
accordingly. This way, offloaded USB transfers could still happen during
system sleep (Suspend-to-RAM).
This involves two key steps:
1. Transfer Status Tracking: Propose offload_usage and corresponding
apis drivers could track USB transfers on the co-processor, ensuring
the system is aware of any ongoing activity.
2. Power Management Adjustment: Modifications to the USB driver stack
(xhci host controller driver, and USB device drivers) allow the
system to sleep (Suspend-to-RAM) without disrupting co-processor
managed USB transfers. This involves adding conditional checks to
bypass some power management operations in the System Sleep model.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly
once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink

responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup

The Gemalto Cinterion PLS83-W modem (cdc_ether) is emitting confusing link
up and down events when the WWAN interface is activated on the modem-side.
Interrupt URBs will in consecutive polls grab:
* Link Connected
* Link Disconnected
* Link Connected
Where the last Connected is then a stable link state.
When the system is under load this may cause the unlink_urbs() work in
__handle_link_change() to not complete before the next usbnet_link_change()
call turns the carrier on again, allowing rx_submit() to queue new SKBs.
In that event the URB queue is filled faster than it can drain, ending up
in a RCU stall:
rcu: INFO: rcu_sched detected expedited stalls on CPUs/tasks: { 0-.... } 33108 jiffies s: 201 root: 0x1/.

Get around the problem by delaying the carrier on to the scheduled work.
This needs a new flag to keep track of the necessary action.
The carrier ok check cannot be removed as it remains required for the
LINK_RESET event flow.

A poorly implemented DisplayPort Alt Mode port partner can indicate
that its pin assignment capabilities are greater than the maximum
value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show
will cause a BRK exception due to an out of bounds array access.

value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop

In the case of handling a USB bus reset, the xhci_discover_or_reset_device
can run without first notifying the xHCI sideband client driver to stop or
prevent the use of the transfer ring. It was seen that when a bus reset
situation happened, the USB offload driver was attempting to fetch the xHCI
transfer ring information, which was already freed.

Introduce XHCI sideband, which manages the USB endpoints being requested by
a client driver. This is used for when client drivers are attempting to
offload USB endpoints to another entity for handling USB transfers. XHCI
sec intr will allow for drivers to fetch the required information about the
transfer ring, so the user can submit transfers independently. Expose the
required APIs for drivers to register and request for a USB endpoint and to
manage XHCI secondary interrupters.

'struct musb_fifo_cfg' are not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename

The Source can drop its output voltage to the minimum of the requested
PPS APDO voltage range when it is in Current Limit Mode. If this voltage
falls within the range of vPpsShutdown, the Source initiates a Hard
Reset and discharges Vbus. However, currently the Sink may disconnect
before the voltage reaches vPpsShutdown, leading to unexpected behavior.
Prevent premature disconnection by setting the Sink's disconnect
threshold to the minimum vPpsShutdown value. Additionally, consider the
voltage drop due to IR drop when calculating the appropriate threshold.
This ensures a robust and reliable interaction between the Source and
Sink during SPR PPS Current Limit Mode operation.

Static devm_usb_phy_match() is only called by API devm_usb_put_phy(), and
the API has no caller now.
Remove the API and the static function.

The active property of port altmode should be writable (to prevent or
allow partner altmodes from entering) and needs to be part of
typec_altmode_desc so we can initialize the port to an inactive state if
desired.

This commit adds a new AMS for responding to a "Get_Revision" request.
Revision message consists of the following fields:
+----------------------------------------------------+
| Header | RMDO |
| No. of data objects = 1 | |
+----------------------------------------------------+
While RMDO consists of:
* B31..28 Revision Major
* B27..24 Revision Minor
* B23..20 Version Major
* B19..16 Version Minor
* B15..0 Reserved, shall be set to zero.
As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.

The meaning of this value is already used in several places,
but with constant values and comments to explain it separately.
It's better to have a central place to do this then use the macro
in those places for better readability.

Here is the big set of USB and Thunderbolt changes for 6.13-rc1.
Overall, a pretty slow development cycle, the majority of the work going
into the debugfs interface for the thunderbolt (i.e. USB4) code, to help
with debugging the myrad ways that hardware vendors get their interfaces
messed up. Other than that, here's the highlights:
- thunderbolt changes and additions to debugfs interfaces
- lots of device tree updates for new and old hardware
- UVC configfs gadget updates and new apis for features
- xhci driver updates and fixes
- dwc3 driver updates and fixes
- typec driver updates and fixes
- lots of other small updates and fixes, full details in the shortlog
All of these have been in linux-next for a while with no reported
problems.
