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

CONFIG_RFS_ACCEL I received a kernel-test-bot report[1] that shows the [-Wunused-but-set-variable] warning. Since the previous commit I made, as the 'Fixes' tag shows, gives users an option to turn on and off the CONFIG_RFS_ACCEL, the issue then can be discovered and reproduced with GCC specifically.

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.

2025-06-27eth: bnxt: take page size into account for page pool recycling ringsJakub Kicinski
The Rx rings are filled with Rx buffers. Which are supposed to fit packet headers (or MTU if HW-GRO is disabled). The aggregation buffers are filled with "device pages". Adjust the sizes of the page pool recycling ring appropriately, based on ratio of the size of the buffer on given ring vs system page size. Otherwise on a system with 64kB pages we end up with >700MB of memory sitting in every single page pool cache. Correct the size calculation for the head_pool. Since the buffers there are always small I'm pretty sure I meant to cap the size at 1k, rather than make it the lowest possible size. With 64k pages 1k cache with a 1k ring is 64x larger than we need.

By digging in the actual source code, we found that commit 7f0a168b0441 ("bnxt_en: Add completion ring pointer in TX and RX ring structures") incorrectly overwrites the event mask for XDP_REDIRECT in bnxt_rx_xdp. We can stably reproduce this crash by returning XDP_TX and XDP_REDIRECT randomly for incoming packets in a naive XDP program. Properly propagate the XDP_REDIRECT events back fixes the crash.

2025-06-17bnxt_en: Update MRU and RSS table of RSS contexts on queue resetPavan Chebbi
The commit under the Fixes tag below which updates the VNICs' RSS and MRU during .ndo_queue_start(), needs to be extended to cover any non-default RSS contexts which have their own VNICs. Without this step, packets that are destined to a non-default RSS context may be dropped after .ndo_queue_start(). We further optimize this scheme by updating the VNIC only if the RX ring being restarted is in the RSS table of the VNIC. Updating the VNIC (in particular setting the MRU to 0) will momentarily stop all traffic to all rings in the RSS table. Any VNIC that has the RX ring excluded from the RSS table can skip this step and avoid the traffic disruption. Note that this scheme is just an improvement. A VNIC with multiple rings in the RSS table will still see traffic disruptions to all rings in the RSS table when one of the rings is being restarted. We are working on a FW scheme that will improve upon this further.

Add a new helper function that will configure MRU and RSS table of a VNIC. This will be useful when we configure both on a VNIC when resetting an RX ring. This function will be used again in the next bug fix patch where we have to reconfigure VNICs for RSS contexts.

2025-06-17bnxt_en: Fix double invocation of bnxt_ulp_stop()/bnxt_ulp_start()Kalesh AP
Before the commit under the Fixes tag below, bnxt_ulp_stop() and bnxt_ulp_start() were always invoked in pairs. After that commit, the new bnxt_ulp_restart() can be invoked after bnxt_ulp_stop() has been called. This may result in the RoCE driver's aux driver .suspend() method being invoked twice. The 2nd bnxt_re_suspend() call will crash when it dereferences a NULL pointer: (NULL ib_device): Handle device suspend call BUG: kernel NULL pointer dereference, address: 0000000000000b78 PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP PTI CPU: 20 UID: 0 PID: 181 Comm: kworker/u96:5 Tainted: G S 6.15.0-rc1 #4 PREEMPT(voluntary) Tainted: [S]=CPU_OUT_OF_SPEC Hardware name: Dell Inc.

2025-05-22eth: bnxt: fix deadlock when xdp is attached or detachedTaehee Yoo
When xdp is attached or detached, dev->ndo_bpf() is called by do_setlink(), and it acquires netdev_lock() if needed. Unlike other drivers, the bnxt driver is protected by netdev_lock while xdp is attached/detached because it sets dev->request_ops_lock to true. So, the bnxt_xdp(), that is callback of ->ndo_bpf should not acquire netdev_lock(). But the xdp_features_{set | clear}_redirect_target() was changed to acquire netdev_lock() internally. It causes a deadlock. To fix this problem, bnxt driver should use xdp_features_{set | clear}_redirect_target_locked() instead.

2025-05-20bnxt_en: Fix netdev locking in ULP IRQ functionsMichael Chan
netdev_lock is already held when calling bnxt_ulp_irq_stop() and bnxt_ulp_irq_restart(). When converting rtnl_lock to netdev_lock, the original code was rtnl_dereference() to indicate that rtnl_lock was already held. rcu_dereference_protected() is the correct conversion after replacing rtnl_lock with netdev_lock. Add a new helper netdev_lock_dereference() similar to rtnl_dereference().
