2025-07-18wifi: rtw89: dynamically update EHT preamble puncturingKuan-Chung Chen
When the 'Disabled Subchannel Bitmap' within the EHT Operation element is changed, mac80211 parse and pass it to the driver. The driver is then updated with this puncturing bitmap to optimize bandwidth usage and prevent interference from degrading performance across the entire channel.

2025-07-17ibmvnic: Use ndo_get_stats64 to fix inaccurate SAR reportingMingming Cao
VNIC testing on multi-core Power systems showed SAR stats drift and packet rate inconsistencies under load. Implements ndo_get_stats64 to provide safe aggregation of queue-level atomic64 counters into rtnl_link_stats64 for use by tools like 'ip -s', 'ifconfig', and 'sar'. Switch to ndo_get_stats64 to align SAR reporting with the standard kernel interface for retrieving netdev stats. This removes redundant per-adapter stat updates, reduces overhead, eliminates cacheline bouncing from hot path updates, and improves the accuracy of reported packet rates.

2025-07-17net/mlx5e: TX, Fix dma unmapping for devmem txDragos Tatulea
net_iovs should have the dma address set to 0 so that netmem_dma_unmap_page_attrs() correctly skips the unmap. This was not done in mlx5 when support for devmem tx was added and resulted in the splat below when the platform iommu was enabled. This patch addresses the issue by using netmem_dma_unmap_addr_set() which handles the net_iov case when setting the dma address. A small refactoring of mlx5e_dma_push() was required to be able to use this API. The function was split in two versions and each version called accordingly. Note that netmem_dma_unmap_addr_set() introduces an additional if case.

2025-07-17ppp: Replace per-CPU recursion counter with lock-owner fieldSebastian Andrzej Siewior
The per-CPU variable ppp::xmit_recursion is protecting against recursion due to wrong configuration of the ppp unit. The per-CPU variable relies on disabled BH for its locking. Without per-CPU locking in local_bh_disable() on PREEMPT_RT this data structure requires explicit locking. The ppp::xmit_recursion is used as a per-CPU boolean. The counter is checked early in the send routing and the transmit path is only entered if the counter is zero. Then the counter is incremented to avoid recursion. It used to detect recursion on channel::downl and ppp::wlock. Create a struct ppp_xmit_recursion and move the counter into it. Add local_lock_t to the struct and use local_lock_nested_bh() for locking. Due to possible nesting, the lock cannot be acquired unconditionally but it requires an owner field to identify recursion before attempting to acquire the lock. The counter is incremented and checked only after the lock is acquired. Since it functions as a boolean rather than a count, and its role is now superseded by the owner field, it can be safely removed.

2025-07-16net/mlx5e: Add device PCIe congestion ethtool statsDragos Tatulea
Implement the PCIe Congestion Event notifier which triggers a work item to query the PCIe Congestion Event object. The result of the congestion state is reflected in the new ethtool stats: * pci_bw_inbound_high: the device has crossed the high threshold for inbound PCIe traffic. * pci_bw_inbound_low: the device has crossed the low threshold for inbound PCIe traffic * pci_bw_outbound_high: the device has crossed the high threshold for outbound PCIe traffic. * pci_bw_outbound_low: the device has crossed the low threshold for outbound PCIe traffic The high and low thresholds are currently configured at 90% and 75%. These are hysteresis thresholds which help to check if the PCI bus on the device side is in a congested state. If low + 1 = high then the device is in a congested state. If low == high then the device is not in a congested state. The counters are also documented. A follow-up patch will make the thresholds configurable.

np->name was being used after calling of_node_put(np), which releases the node and can lead to a use-after-free bug. Previously, of_node_put(np) was called unconditionally after of_find_device_by_node(np), which could result in a use-after-free if pdev is NULL. This patch moves of_node_put(np) after the error check to ensure the node is only released after both the error and success cases are handled appropriately, preventing potential resource issues.

2025-07-16net/mlx5: Correctly set gso_size when LRO is usedChristoph Paasch
gso_size is expected by the networking stack to be the size of the payload (thus, not including ethernet/IP/TCP-headers). However, cqe_bcnt is the full sized frame (including the headers). Dividing cqe_bcnt by lro_num_seg will then give incorrect results. For example, running a bpftrace higher up in the TCP-stack (tcp_event_data_recv), we commonly have gso_size set to 1450 or 1451 even though in reality the payload was only 1448 bytes. This can have unintended consequences: - In tcp_measure_rcv_mss() len will be for example 1450, but. rcv_mss will be 1448 (because tp->advmss is 1448). Thus, we will always recompute scaling_ratio each time an LRO-packet is received. - In tcp_gro_receive(), it will interfere with the decision whether or not to flush and thus potentially result in less gro'ed packets. So, we need to discount the protocol headers from cqe_bcnt so we can actually divide the payload by lro_num_seg to get the real gso_size. v2: - Use "(unsigned char *)tcp + tcp->doff * 4 - skb->data)" to compute header-len (Tariq Toukan <tariqt@nvidia.com>) - Improve commit-message (Gal Pressman <gal@nvidia.com>) Fixes: e586b3b0baee ("net/mlx5: Ethernet Datapath files") Signed-off-by: Christoph Paasch <cpaasch@openai.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Gal Pressman <gal@nvidia.com> Link: https://patch.msgid.link/20250715-cpaasch-pf-925-investigate-incorrect-gso_size-on-cx-7-nic-v2-1-e06c3475f3ac@openai.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-16ovpn: reset GSO metadata after decapsulationRalf Lici
The ovpn_netdev_write() function is responsible for injecting decapsulated and decrypted packets back into the local network stack. Prior to this patch, the skb could retain GSO metadata from the outer, encrypted tunnel packet. This original GSO metadata, relevant to the sender's transport context, becomes invalid and misleading for the tunnel/data path once the inner packet is exposed. Leaving this stale metadata intact causes internal GSO validation checks further down the kernel's network stack (validate_xmit_skb()) to fail, leading to packet drops. The reasons for these failures vary by protocol, for example: - for ICMP, no offload handler is registered; - for TCP and UDP, the respective offload handlers return errors when comparing skb->len to the outdated skb_shinfo(skb)->gso_size. By calling skb_gso_reset(skb) we ensure the inner packet is presented to gro_cells_receive() with a clean state, correctly indicating it is an individual packet from the perspective of the local stack. This change eliminates the "Driver has suspect GRO implementation, TCP performance may be compromised" warning and improves overall TCP performance by allowing GSO/GRO to function as intended on the decapsulated traffic.

OpenVPN allows users to configure a FW mark on sockets used to communicate with other peers. The mark is set by means of the `SO_MARK` Linux socket option. However, in the ovpn UDP code path, the socket's `sk_mark` value is currently ignored and it is not propagated to outgoing `skbs`. This commit ensures proper inheritance of the field by setting `skb->mark` to `sk->sk_mark` before handing the `skb` to the network stack for transmission.

In the original code, double free pages cause kernel panic: [ 876.949834] __irq_exit_rcu+0xc7/0x130 [ 876.949836] common_interrupt+0xb8/0xd0 [ 876.949838] </IRQ> [ 876.949838] <TASK> [ 876.949840] asm_common_interrupt+0x22/0x40 [ 876.949841] RIP: 0010:cpuidle_enter_state+0xc2/0x420 [ 876.949843] Code: 00 00 e8 d1 1d 5e ff e8 ac f0 ff ff 49 89 c5 0f 1f 44 00 00 31 ff e8 cd fc 5c ff 45 84 ff 0f 85 40 02 00 00 fb 0f 1f 44 00 00 <45> 85 f6 0f 88 84 01 00 00 49 63 d6 48 8d 04 52 48 8d 04 82 49 8d [ 876.949844] RSP: 0018:ffffaa7340267e78 EFLAGS: 00000246 [ 876.949845] RAX: ffff9e3f135be000 RBX: 0000000000000002 RCX: 0000000000000000 [ 876.949846] RDX: 000000cc2dc4cb7c RSI: ffffffff89ee49ae RDI: ffffffff89ef9f9e [ 876.949847] RBP: ffff9e378f940800 R08: 0000000000000002 R09: 00000000000000ed [ 876.949848] R10: 000000000000afc8 R11: ffff9e3e9e5a9b6c R12: ffffffff8a6d8580 [ 876.949849] R13: 000000cc2dc4cb7c R14: 0000000000000002 R15: 0000000000000000 [ 876.949852] ? cpuidle_enter_state+0xb3/0x420 [ 876.949855] cpuidle_enter+0x29/0x40 [ 876.949857] cpuidle_idle_call+0xfd/0x170 [ 876.949859] do_idle+0x7a/0xc0 [ 876.949861] cpu_startup_entry+0x25/0x30 [ 876.949862] start_secondary+0x117/0x140 [ 876.949864] common_startup_64+0x13e/0x148 [ 876.949867] </TASK> [ 876.949868] ---[ end trace 0000000000000000 ]--- [ 876.949869] ------------[ cut here ]------------ [ 876.949870] list_del corruption, ffffead40445a348->next is NULL [ 876.949873] WARNING: CPU: 14 PID: 0 at lib/list_debug.c:52 __list_del_entry_valid_or_report+0x67/0x120 [ 876.949875] Modules linked in: snd_hrtimer(E) bnep(E) binfmt_misc(E) amdgpu(E) squashfs(E) vfat(E) loop(E) fat(E) amd_atl(E) snd_hda_codec_realtek(E) intel_rapl_msr(E) snd_hda_codec_generic(E) intel_rapl_common(E) snd_hda_scodec_component(E) snd_hda_codec_hdmi(E) snd_hda_intel(E) edac_mce_amd(E) snd_intel_dspcfg(E) snd_hda_codec(E) snd_hda_core(E) amdxcp(E) kvm_amd(E) snd_hwdep(E) gpu_sched(E) drm_panel_backlight_quirks(E) cec(E) snd_pcm(E) drm_buddy(E) snd_seq_dummy(E) drm_ttm_helper(E) btusb(E) kvm(E) snd_seq_oss(E) btrtl(E) ttm(E) btintel(E) snd_seq_midi(E) btbcm(E) drm_exec(E) snd_seq_midi_event(E) i2c_algo_bit(E) snd_rawmidi(E) bluetooth(E) drm_suballoc_helper(E) irqbypass(E) snd_seq(E) ghash_clmulni_intel(E) sha512_ssse3(E) drm_display_helper(E) aesni_intel(E) snd_seq_device(E) rfkill(E) snd_timer(E) gf128mul(E) drm_client_lib(E) drm_kms_helper(E) snd(E) i2c_piix4(E) joydev(E) soundcore(E) wmi_bmof(E) ccp(E) k10temp(E) i2c_smbus(E) gpio_amdpt(E) i2c_designware_platform(E) gpio_generic(E) sg(E) [ 876.949914] i2c_designware_core(E) sch_fq_codel(E) parport_pc(E) drm(E) ppdev(E) lp(E) parport(E) fuse(E) nfnetlink(E) ip_tables(E) ext4 crc16 mbcache jbd2 sd_mod sfp mdio_i2c i2c_core txgbe ahci ngbe pcs_xpcs libahci libwx r8169 phylink libata realtek ptp pps_core video wmi [ 876.949933] CPU: 14 UID: 0 PID: 0 Comm: swapper/14 Kdump: loaded Tainted: G W E 6.16.0-rc2+ #20 PREEMPT(voluntary) [ 876.949935] Tainted: [W]=WARN, [E]=UNSIGNED_MODULE [ 876.949936] Hardware name: Micro-Star International Co., Ltd.
