git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next 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 - Add a new neighbor flag ("extern_valid"), which cedes refresh 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 - Support inspecting ref_tracker state via DebugFS - Don't force bonding advertisement frames tx to ~333 ms boundaries. Add broadcast_neighbor option to send ARP/ND on all bonded links - Allow providing upcall pid for the 'execute' command in openvswitch - Remove DCCP support from Netfilter's conntrack - Disallow multiple packet duplications in the queuing layer - Prevent use of deprecated iptables code on PREEMPT_RT Driver API: - Support RSS and hashing configuration over ethtool Netlink - Add dedicated ethtool callbacks for getting and setting hashing fields - Add support for power budget evaluation strategy in PSE / Power-over-Ethernet.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer cleanups from Thomas Gleixner: "A treewide cleanup of struct cycle_counter const annotations. The initial idea of making them const was correct as they were seperate instances. When they got embedded into larger data structures, which are even modified by the callback this got moot. The only reason why this went unnoticed is that the required container_of() casts the const attribute forcefully away. Stop pretending that it is const" * tag 'timers-cleanups-2025-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: time/timecounter: Fix the lie that struct cyclecounter is const

2025-07-15net: libwx: properly reset Rx ring descriptorJiawen Wu
When device reset is triggered by feature changes such as toggling Rx VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The hardware descriptor ring may retain stale values from previous sessions. And only set the length to 0 in rx_desc[0] would result in building malformed SKBs. Fix it to ensure a clean slate after device reset. [ 549.186435] [ C16] ------------[ cut here ]------------ [ 549.186457] [ C16] kernel BUG at net/core/skbuff.c:2814!

2025-07-15net: libwx: fix the using of Rx buffer DMAJiawen Wu
The wx_rx_buffer structure contained two DMA address fields: 'dma' and 'page_dma'. However, only 'page_dma' was actually initialized and used to program the Rx descriptor. But 'dma' was uninitialized and used in some paths. This could lead to undefined behavior, including DMA errors or use-after-free, if the uninitialized 'dma' was used. Althrough such error has not yet occurred, it is worth fixing in the code.

2025-07-03net: ngbe: specify IRQ vector when the number of VFs is 7Jiawen Wu
For NGBE devices, the queue number is limited to be 1 when SRIOV is enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is used for queue, based on the previous patches. But for the hardware design, the IRQ vector[1] must be allocated for use by the VF[6] when the number of VFs is 7. So the IRQ vector[0] should be shared for PF MISC and QUEUE interrupts. +-----------+----------------------+ | Vector | Assigned To | +-----------+----------------------+ | Vector 0 | PF MISC and QUEUE | | Vector 1 | VF 6 | | Vector 2 | VF 5 | | Vector 3 | VF 4 | | Vector 4 | VF 3 | | Vector 5 | VF 2 | | Vector 6 | VF 1 | | Vector 7 | VF 0 | +-----------+----------------------+ Minimize code modifications, only adjust the IRQ vector number for this case.

2025-07-03net: wangxun: revert the adjustment of the IRQ vector sequenceJiawen Wu
Due to hardware limitations of NGBE, queue IRQs can only be requested on vector 0 to 7. When the number of queues is set to the maximum 8, the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by MISC interrupt, and althrough the vector 8 is used by queue interrupt, it is unable to receive packets. This will cause some packets to be dropped when RSS is enabled and they are assigned to queue 8. So revert the adjustment of the MISC IRQ location, to make it be the last one in IRQ vectors.

2025-07-01time/timecounter: Fix the lie that struct cyclecounter is constGreg Kroah-Hartman
In both the read callback for struct cyclecounter, and in struct timecounter, struct cyclecounter is declared as a const pointer. Unfortunatly, a number of users of this pointer treat it as a non-const pointer as it is burried in a larger structure that is heavily modified by the callback function when accessed. This lie had been hidden by the fact that container_of() "casts away" a const attribute of a pointer without any compiler warning happening at all. Fix this all up by removing the const attribute in the needed places so that everyone can see that the structure really isn't const, but can, and is, modified by the users of it.

For the new SW-FW interaction, missing the error return if there is an unknown command. It causes the driver to mistakenly believe that the interaction is complete.
