Merge tag 'net-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Support HW queue leasing, allowing containers to be granted access to HW queues for zero-copy operations and AF_XDP - Number of code moves to help the compiler with inlining. Avoid output arguments for returning drop reason where possible - Rework drop handling within qdiscs to include more metadata about the reason and dropping qdisc in the tracepoints - Remove the rtnl_lock use from IP Multicast Routing - Pack size information into the Rx Flow Steering table pointer itself. This allows making the table itself a flat array of u32s, thus making the table allocation size a power of two - Report TCP delayed ack timer information via socket diag - Add ip_local_port_step_width sysctl to allow distributing the randomly selected ports more evenly throughout the allowed space - Add support for per-route tunsrc in IPv6 segment routing - Start work of switching sockopt handling to iov_iter - Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid buffer size drifting up - Support MSG_EOR in MPTCP - Add stp_mode attribute to the bridge driver for STP mode selection. This addresses concerns about call_usermodehelper() usage - Remove UDP-Lite support (as announced in 2023) - Remove support for building IPv6 as a module. Remove the now unnecessary function calling indirection Cross-tree stuff: - Move Michael MIC code from generic crypto into wireless, it's considered insecure but some WiFi networks still need it Netfilter: - Switch nft_fib_ipv6 module to no longer need temporary dst_entry object allocations by using fib6_lookup() + RCU. Florian W reports this gets us ~13% higher packet rate - Convert IPVS's global __ip_vs_mutex to per-net service_mutex and switch the service tables to be per-net. Convert some code that walks the service lists to use RCU instead of the service_mutex - Add more opinionated input validation to lower security exposure - Make IPVS hash tables to be per-netns and resizable Wireless: - Finished assoc frame encryption/EPPKE/802.1X-over-auth - Radar detection improvements - Add 6 GHz incumbent signal detection APIs - Multi-link support for FILS, probe response templates and client probing - New APIs and mac80211 support for NAN (Neighbor Aware Networking, aka Wi-Fi Aware) so less work must be in firmware Driver API: - Add numerical ID for devlink instances (to avoid having to create fake bus/device pairs just to have an ID). Support shared devlink instances which span multiple PFs - Add standard counters for reporting pause storm events (implement in mlx5 and fbnic) - Add configuration API for completion writeback buffering (implement in mana) - Support driver-initiated change of RSS context sizes - Support DPLL monitoring input frequency (implement in zl3073x) - Support per-port resources in devlink (implement in mlx5) Misc: - Expand the YAML spec for Netfilter Drivers - Software: - macvlan: support multicast rx for bridge ports with shared source MAC address - team: decouple receive and transmit enablement for IEEE 802.3ad LACP "independent control" - Ethernet high-speed NICs: - nVidia/Mellanox: - support high order pages in zero-copy mode (for payload coalescing) - support multiple packets in a page (for systems with 64kB pages) - Broadcom 25-400GE (bnxt): - implement XDP RSS hash metadata extraction - add software fallback for UDP GSO, lowering the IOMMU cost - Broadcom 800GE (bnge): - add link status and configuration handling - add various HW and SW statistics - Marvell/Cavium: - NPC HW block support for cn20k - Huawei (hinic3): - add mailbox / control queue - add rx VLAN offload - add driver info and link management - Ethernet NICs: - Marvell/Aquantia: - support reading SFP module info on some AQC100 cards - Realtek PCI (r8169): - add support for RTL8125cp - Realtek USB (r8152): - support for the RTL8157 5Gbit chip - add 2500baseT EEE status/configuration support - Ethernet NICs embedded and off-the-shelf IP: - Synopsys (stmmac): - cleanup and reorganize SerDes handling and PCS support - cleanup descriptor handling and per-platform data - cleanup and consolidate MDIO defines and handling - shrink driver memory use for internal structures - improve Tx IRQ coalescing - improve TCP segmentation handling - add support for Spacemit K3 - Cadence (macb): - support PHYs that have inband autoneg disabled with GEM - support IEEE 802.3az EEE - rework usrio capabilities and handling - AMD (xgbe): - improve power management for S0i3 - improve TX resilience for link-down handling - Virtual: - Google cloud vNIC: - support larger ring sizes in DQO-QPL mode - improve HW-GRO handling - support UDP GSO for DQO format - PCIe NTB: - support queue count configuration - Ethernet PHYs: - automatically disable PHY autonomous EEE if MAC is in charge - Broadcom: - add BCM84891/BCM84892 support - Micrel: - support for LAN9645X internal PHY - Realtek: - add RTL8224 pair order support - support PHY LEDs on RTL8211F-VD - support spread spectrum clocking (SSC) - Maxlinear: - add PHY-level statistics via ethtool - Ethernet switches: - Maxlinear (mxl862xx): - support for bridge offloading - support for VLANs - support driver statistics - Bluetooth: - large number of fixes and new device IDs - Mediatek: - support MT6639 (MT7927) - support MT7902 SDIO - WiFi: - Intel (iwlwifi): - UNII-9 and continuing UHR work - MediaTek (mt76): - mt7996/mt7925 MLO fixes/improvements - mt7996 NPU support (HW eth/wifi traffic offload) - Qualcomm (ath12k): - monitor mode support on IPQ5332 - basic hwmon temperature reporting - support IPQ5424 - Realtek: - add USB RX aggregation to improve performance - add USB TX flow control by tracking in-flight URBs - Cellular: - IPA v5.2 support"* tag 'net-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1561 commits) net: pse-pd: fix kernel-doc function name for pse_control_find_by_id() wireguard: device: use exit_rtnl callback instead of manual rtnl_lock in pre_exit wireguard: allowedips: remove redundant space tools: ynl: add sample for wireguard wireguard: allowedips: Use kfree_rcu() instead of call_rcu() MAINTAINERS: Add netkit selftest files selftests/net: Add additional test coverage in nk_qlease selftests/net: Split netdevsim tests from HW tests in nk_qlease tools/ynl: Make YnlFamily closeable as a context manager net: airoha: Add missing PPE configurations in airoha_ppe_hw_init() net: airoha: Fix VIP configuration for AN7583 SoC net: caif: clear client service pointer on teardown net: strparser: fix skb_head leak in strp_abort_strp() net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete() selftests/bpf: add test for xdp_master_redirect with bond not up net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master net: airoha: Remove PCE_MC_EN_MASK bit in REG_FE_PCE_CFG configuration sctp: disable BH before calling udp_tunnel_xmit_skb() sctp: fix missing encap_port propagation for GSO fragments net: airoha: Rely on net_device pointer in ETS callbacks ...

e531a081065d274a14f54441a38e1849453d06ec - Merge branch 'convert-config_ipv6-to-built-in-and-remove-stubs'

Sun, 29 Mar 2026 20:21:29 +0200

Merge branch 'convert-config_ipv6-to-built-in-and-remove-stubs'Fernando Fernandez Mancera says:====================Convert CONFIG_IPV6 to built-in and remove stubsHistorically, the Linux kernel has supported compiling the IPv6 stack asa loadable module. While this made sense in the early days of IPv6adoption, modern deployments and distributions overwhelmingly eitherbuild IPv6 directly into the kernel (CONFIG_IPV6=y) or disable itentirely (CONFIG_IPV6=n). The modular IPv6 use-case offers image sizeand memory savings for specific setups, this benefit is outweighed bythe architectural burden it imposes on the subsystems on implementationand maintenance.In addition, most of the distributions are already using CONFIG_IPV6=yby default [1], including openWRT [2] and Android gki_defconfig [3]. Sothis won't have an impact on them. The most impacted architecture wouldprobably be arm64 as their default config is still using CONFIG_IPV6=m.To allow core networking, BPF, Netfilter, and various device drivers tosafely interact with a potentially unloaded IPv6 module, the kernelrelies on indirect call structures like ipv6_stub, ipv6_bpf_stub, andnf_ipv6_ops, along with dynamic RCU registrations for things like ICMPv6senders.This patch series addresses this by changing CONFIG_IPV6 from a tristateto a boolean, enforcing that IPv6 is either built-in or disabled. Thisallows us to completely rip out the stub infrastructures and safelyreplace them with direct function calls.The bloat-o-meter report the following results for m68k, arm64, x86_64defconfig.m68k (keep on mind that CONFIG_IPV6 is disabled now):add/remove: 65/938 grow/shrink: 36/254 up/down: 3022/-49692 (-46670)arm64:add/remove: 1251/265 grow/shrink: 81/46 up/down: 448740/-71519 (377221)x86_64:add/remove: 62/98 grow/shrink: 10/39 up/down: 2497/-4357 (-1860)Considering that each new kernel release increases sizes by 30-40KiB onaverage, this size increase isn't a huge jump for the distributions thatare still using CONFIG_IPV6=m. For the ones that are already usingCONFIG_IPV6=y, the size is reduced actually.All the patches has been independently build tested. With allmodconfigand allmodconfig + CONFIG_IPV6=n. In addition, net selftest has been runagainst them on virtme-ng.The series applied as a whole as been tested with allyesconfig and alsoallyesconfig + CONFIG_IPV6=n but not all patches has been independentlytested this way.[1] https://github.com/nyrahul/linux-kernel-configs[2] https://github.com/openwrt/openwrt/commit/832e7b817221d288df76b763ca12c585365db5d8[3] https://android.googlesource.com/kernel/common/+/refs/heads/android-mainline/arch/arm64/configs/gki_defconfig====================Link: https://patch.msgid.link/20260325120928.15848-1-fmancera@suse.deSigned-off-by: Jakub Kicinski List of files: /linux/net/l2tp/Kconfig

309b905deee595619cc38719f48d63d57b8bff3d - ipv6: convert CONFIG_IPV6 to built-in only and clean up Kconfigs

Wed, 25 Mar 2026 13:08:42 +0100

ipv6: convert CONFIG_IPV6 to built-in only and clean up KconfigsMaintaining a modular IPv6 stack offers image size savings for specificsetups, this benefit is outweighed by the architectural burden itimposes on the subsystems on implementation and maintenance. Therefore,drop it.Change CONFIG_IPV6 from tristate to bool. Remove all Kconfigdependencies across the tree that explicitly checked for IPV6=m. Inaddition, remove MODULE_DESCRIPTION(), MODULE_ALIAS(), MODULE_AUTHOR()and MODULE_LICENSE().This is also replacing module_init() by device_initcall(). It is notpossible to use fs_initcall() as IPv4 does because that creates a racecondition on IPv6 addrconf.Finally, modify the default configs from CONFIG_IPV6=m to CONFIG_IPV6=yexcept for m68k as according to the bloat-o-meter the image isincreasing by 330KB~ and that isn't acceptable. Instead, disable IPv6 onthis architecture by default. This is aligned with m68k RAM requirementsand recommendations [1].[1] http://www.linux-m68k.org/faq/ram.htmlSigned-off-by: Fernando Fernandez Mancera Tested-by: Ricardo B.
