If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance.

caif: remove CAIF NETWORK LAYERRemove CAIF (Communication CPU to Application CPU Interface), theST-Ericsson modem protocol. The subsystem has been orphaned since 2013.The last meaningful changes from the maintainers were in March 2013: a8c7687bf216 ("caif_virtio: Check that vringh_config is not null") b2273be8d2df ("caif_virtio: Use vringh_notify_enable correctly") 0d2e1a2926b1 ("caif_virtio: Introduce caif over virtio")Not-so-coincidentally, according to "the Internet" ST-Ericsson officiallyshut down its modem joint venture in Aug 2013.If anyone is using this code please yell!In the 13 years since, the code has accumulated 200 non-merge commits,of which 71 were cross-tree API changes, 21 carried Fixes: tags, andthe remaining ~110 were cleanups, doc conversions, treewide refactors,and one partial removal (caif_hsi, ca75bcf0a83b).We are still getting fixes to this code, in the last 10 days there were3 reports on security@ about CAIF that I have been CCed on.UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and theSELinux classmap entry are intentionally kept for ABI stability.Acked-by: Michael S.

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/drivers/net/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.

24fbd3967f3fdaad5f93e0d35ae870ed25fb2c3a - virtio_net: add page_pool support for buffer allocation

Tue, 10 Mar 2026 19:31:04 +0100

virtio_net: add page_pool support for buffer allocationUse page_pool for RX buffer allocation in mergeable and small buffermodes to enable page recycling and avoid repeated page allocator calls.skb_mark_for_recycle() enables page reuse in the network stack.Big packets mode is unchanged because it uses page->private for linkedlist chaining of multiple pages per buffer, which conflicts withpage_pool's internal use of page->private.Implement conditional DMA premapping using virtqueue_dma_dev():- When non-NULL (vhost, virtio-pci): use PP_FLAG_DMA_MAP with page_pool handling DMA mapping, submit via virtqueue_add_inbuf_premapped()- When NULL (VDUSE, direct physical): page_pool handles allocation only, submit via virtqueue_add_inbuf_ctx()This preserves the DMA premapping optimization from commit 31f3cd4e5756b("virtio-net: rq submits premapped per-buffer") while adding page_poolsupport as a prerequisite for future zero-copy features (devmem TCP,io_uring ZCRX).Page pools are created in probe and destroyed in remove (not open/close),following existing driver behavior where RX buffers remain in virtqueuesacross interface state changes.Signed-off-by: Vishwanath Seshagiri Acked-by: Jason Wang Acked-by: Michael S.

Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull 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. - Ethernet high-speed NICs: - Broadcom (bnxt, bng): - bnxt: add FW interface update to support FEC stats histogram and NVRAM defragmentation - bng: add TSO and H/W GRO support - nVidia/Mellanox (mlx5): - improve latency of channel restart operations, reducing the used H/W resources - add TSO support for UDP over GRE over VLAN - add flow counters support for hardware steering (HWS) rules - use a static memory area to store headers for H/W GRO, leading to 12% RX tput improvement - Intel (100G, ice, idpf): - ice: reorganizes layout of Tx and Rx rings for cacheline locality and utilizes __cacheline_group* macros on the new layouts - ice: introduces Synchronous Ethernet (SyncE) support - Meta (fbnic): - adds debugfs for firmware mailbox and tx/rx rings vectors - Ethernet virtual: - geneve: introduce GRO/GSO support for double UDP encapsulation - Ethernet NICs consumer, and embedded: - Synopsys (stmmac): - some code refactoring and cleanups - RealTek (r8169): - add support for RTL8127ATF (10G Fiber SFP) - add dash and LTR support - Airoha: - AN8811HB 2.5 Gbps phy support - Freescale (fec): - add XDP zero-copy support - Thunderbolt: - add get link setting support to allow bonding - Renesas: - add support for RZ/G3L GBETH SoC - Ethernet switches: - Maxlinear: - support R(G)MII slow rate configuration - add support for Intel GSW150 - Motorcomm (yt921x): - add DCB/QoS support - TI: - icssm-prueth: support bridging (STP/RSTP) via the switchdev framework - Ethernet PHYs: - Realtek: - enable SGMII and 2500Base-X in-band auto-negotiation - simplify and reunify C22/C45 drivers - Micrel: convert bindings to DT schema - CAN: - move skb headroom content into skb extensions, making CAN metadata access more robust - CAN drivers: - rcar_canfd: - add support for FD-only mode - add support for the RZ/T2H SoC - sja1000: cleanup the CAN state handling - WiFi: - implement EPPKE/802.1X over auth frames support - split up drop reasons better, removing generic RX_DROP - additional FTM capabilities: 6 GHz support, supported number of spatial streams and supported number of LTF repetitions - better mac80211 iterators to enumerate resources - initial UHR (Wi-Fi 8) support for cfg80211/mac80211 - WiFi drivers: - Qualcomm/Atheros: - ath11k: support for Channel Frequency Response measurement - ath12k: a significant driver refactor to support multi-wiphy devices and and pave the way for future device support in the same driver (rather than splitting to ath13k) - ath12k: support for the QCC2072 chipset - Intel: - iwlwifi: partial Neighbor Awareness Networking (NAN) support - iwlwifi: initial support for U-NII-9 and IEEE 802.11bn - RealTek (rtw89): - preparations for RTL8922DE support - Bluetooth: - implement setsockopt(BT_PHY) to set the connection packet type/PHY - set link_policy on incoming ACL connections - Bluetooth drivers: - btusb: add support for MediaTek7920, Realtek RTL8761BU and 8851BE - btqca: add WCN6855 firmware priority selection feature"* tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1254 commits) bnge/bng_re: Add a new HSI net: macb: Fix tx/rx malfunction after phy link down and up af_unix: Fix memleak of newsk in unix_stream_connect(). net: ti: icssg-prueth: Add optional dependency on HSR net: dsa: add basic initial driver for MxL862xx switches net: mdio: add unlocked mdiodev C45 bus accessors net: dsa: add tag format for MxL862xx switches dt-bindings: net: dsa: add MaxLinear MxL862xx selftests: drivers: net: hw: Modify toeplitz.c to poll for packets octeontx2-pf: Unregister devlink on probe failure net: renesas: rswitch: fix forwarding offload statemachine ionic: Rate limit unknown xcvr type messages tcp: inet6_csk_xmit() optimization tcp: populate inet->cork.fl.u.ip6 in tcp_v6_syn_recv_sock() tcp: populate inet->cork.fl.u.ip6 in tcp_v6_connect() ipv6: inet6_csk_xmit() and inet6_csk_update_pmtu() use inet->cork.fl.u.ip6 ipv6: use inet->cork.fl.u.ip6 and np->final in ip6_datagram_dst_update() ipv6: use np->final in inet6_sk_rebuild_header() ipv6: add daddr/final storage in struct ipv6_pinfo net: stmmac: qcom-ethqos: fix qcom_ethqos_serdes_powerup() ...

Merge branch 'net-netconsole-convert-to-nbcon-console-infrastructure'Breno Leitao says:====================net: netconsole: convert to NBCON console infrastructureThis series adds support for the nbcon (new buffer console) infrastructureto netconsole, enabling lock-free, priority-based console operations thatare safer in crash scenarios.The implementation is introduced in three steps:0) Extend printk to expose CPU and taskname (task->comm) where the printk originated from. (Thanks John and Petr for the support in getting this done)1) Refactor the message fragmentation logic into a reusable helper function2) Extend nbcon support to non-extended (basic) consoles using the same infrastructure.The initial discussion about it appeared a while ago in [1], in order tosolve Mike's HARDIRQ-safe -> HARDIRQ-unsafe lock order warning, and the rootcause is that some hosts were calling IRQ unsafe locks from inside consolelock.At that time, we didn't have the CON_NBCON_ATOMIC_UNSAFE yet. Johnkindly implemented CON_NBCON_ATOMIC_UNSAFE in 187de7c212e5 ("printk:nbcon: Allow unsafe write_atomic() for panic"), and now we canimplement netconsole on top of nbcon.Important to note that netconsole continues to call netpoll and thenetwork TX helpers with interrupt disable, given the TX are called withtarget_list_lock.====================Link: https://patch.msgid.link/20260206-nbcon-v7-0-62bda69b1b41@debian.orgSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/Kconfig
