Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core & protocols:
- A significant effort all around the stack to guide the compiler to make the right choice when inlining code, to avoid unneeded calls for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text size increases, as in many cases the call generated more code than the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete, also allow the user-space enabling it on a per network namespace basis.
- Add support for memory providers with large (above 4K) rx buffer. Paired with hw-gro, larger rx buffer sizes reduce the number of buffers traversing the stack, dincreasing single stream CPU usage by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the RX path, the TX path and the NIC drivers, and is possible because user-space taps can now interpret correctly such packets without the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is resolved out of a different interface than the one specified, aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the rate shaper of sch_cake across multiple CPUs, while still enforcing a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to netconsole, enabling lock-free, priority-based console operations that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information, saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented optimizations.
- Support netconsole automatic target recovery, allowing netconsole to reestablish targets when underlying low-level interface comes back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties, to generalize polarity inversion requirements for differential signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers:
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX ring count retrieval. Also remove the legacy fallback path.

Merge branch 'ptp-vmclock-add-vm-generation-counter-and-acpi-notification'
Takahiro Itazuri says:
==================== ptp: vmclock: Add VM generation counter and ACPI notification
Similarly to live migration, starting a VM from some serialized state (aka snapshot) is an event which calls for adjusting guest clocks, hence a hypervisor should increase the disruption_marker before resuming the VM vCPUs, letting the guest know.
However, loading a snapshot, is slightly different than live migration, especially since we can start multiple VMs from the same serialized state. Apart from adjusting clocks, the guest needs to take additional action during such events, e.g. recreate UUIDs, reset network adapters/connections, reseed entropy pools, etc. These actions are not necessary during live migration. This calls for a differentiation between the two triggering events.
We differentiate between the two events via an extra field in the vmclock_abi, called vm_generation_counter. Whereas hypervisors should increase the disruption marker in both cases, they should only increase vm_generation_counter when a snapshot is loaded in a VM (not during live migration).
Additionally, we attach an ACPI notification to VMClock. Implementing the notification is optional for the device. VMClock device will declare that it implements the notification by setting VMCLOCK_FLAG_NOTIFICATION_PRESENT bit in vmclock_abi flags. Hypervisors that implement the notification must send an ACPI notification every time seq_count changes to an even number. The driver will propagate these notifications to userspace via the poll() interface. ====================

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism has some similarities with IPsec and TLS, but offers superior HW offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than one congestion notification signal per RTT and is a building block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA hosts, this improves TCP and UDP RX performances significantly on such HW
- Increase the default socket memory buffer limits from 256K to 4M to better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making dump operating scaling linearly and avoiding unneeded synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per bridge instead of one entry per port; this makes the dump order of magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently introduced core infrastructure (skb deferral free) and adopting recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing code duplication
- Supports pulling data from an skb frag into the linear area of an XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML parser
Driver API:
- Support using IPv6 Flow Label in Rx hash computation and RSS queue selection
- Introduce API for fetching the DMA device for a given queue, allowing TCP zerocopy RX on more H/W setups
- Make XDP helpers compatible with unreadable memory, allowing more easily building DevMem-enabled drivers with a unified XDP/skbs datapath
- Add a new dedicated ethtool callback enabling drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration
- Introduce a burst period for the health reporter, allowing better handling of multiple errors due to the same root cause
- Support for DPLL phase offset exponential moving average, controlling the average smoothing factor
Device drivers:
- Add a new Huawei driver for 3rd gen NIC (hinic3)
- Add a new SpacemiT driver for K1 ethernet MAC

==================== ptp: add pulse signal loopback support for debugging
Some PTP devices support looping back the periodic pulse signal for debugging. For example, the PTP device of QorIQ platform and the NETC v4 Timer has the ability to loop back the pulse signal and record the extts events for the loopback signal. So we can make sure that the pulse intervals and their phase alignment are correct from the perspective of the emitting PHC's time base. In addition, we can use this loopback feature as a built-in extts event generator when we have no external equipment which does that. Therefore, add the generic debugfs interfaces to the ptp_clock driver. The first two patch are separated from the previous patch set [1]. The third patch is new added.

ptp: netc: add NETC V4 Timer PTP driver support
NETC V4 Timer provides current time with nanosecond resolution, precise periodic pulse, pulse on timeout (alarm), and time capture on external pulse support. And it supports time synchronization as required for IEEE 1588 and IEEE 802.1AS-2020.
Inside NETC, ENETC can capture the timestamp of the sent/received packet through the PHC provided by the Timer and record it on the Tx/Rx BD. And through the relevant PHC interfaces provided by the driver, the enetc V4 driver can support PTP time synchronization.
In addition, NETC V4 Timer is similar to the QorIQ 1588 timer, but it is not exactly the same. The current ptp-qoriq driver is not compatible with NETC V4 Timer, most of the code cannot be reused, see below reasons.
1. The architecture of ptp-qoriq driver makes the register offset fixed, however, the offsets of all the high registers and low registers of V4 are swapped, and V4 also adds some new registers. so extending ptp-qoriq to make it compatible with V4 Timer is tantamount to completely rewriting ptp-qoriq driver.
2. The usage of some functions is somewhat different from QorIQ timer, such as the setting of TCLK_PERIOD and TMR_ADD, the logic of configuring PPS, etc., so making the driver compatible with V4 Timer will undoubtedly increase the complexity of the code and reduce readability.
3. QorIQ is an expired brand. It is difficult for us to verify whether it works stably on the QorIQ platforms if we refactor the driver, and this will make maintenance difficult, so refactoring the driver obviously does not bring any benefits.
Therefore, add this new driver for NETC V4 Timer. Note that the missing features like PEROUT, PPS and EXTTS will be added in subsequent patches.
