Pull networking deletions from Jakub Kicinski: "Delete some obsolete networking code Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. 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. Let's try to put the rest of this code behind us" * tag 'net-deletions' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: drivers: net: 8390: wd80x3: Remove this driver drivers: net: 8390: ultra: Remove this driver drivers: net: 8390: AX88190: Remove this driver drivers: net: fujitsu: fmvj18x: Remove this driver drivers: net: smsc: smc91c92: Remove this driver drivers: net: smsc: smc9194: Remove this driver drivers: net: amd: nmclan: Remove this driver drivers: net: amd: lance: Remove this driver drivers: net: 3com: 3c589: Remove this driver drivers: net: 3com: 3c574: Remove this driver drivers: net: 3com: 3c515: Remove this driver drivers: net: 3com: 3c509: Remove this driver net: packetengines: remove obsolete yellowfin driver and vendor dir net: packetengines: remove obsolete hamachi driver net: remove unused ATM protocols and legacy ATM device drivers net: remove ax25 and amateur radio (hamradio) subsystem net: remove ISDN subsystem and Bluetooth CMTP caif: remove CAIF NETWORK LAYER

ARM: 9472/1: fix race condition on PG_dcache_clean in __sync_icache_dcache()

2026-04-24T14:12:52+00:00

This bug was already discovered and fixed for arm64 in commit 588a513d3425 ("arm64: Fix race condition on PG_dcache_clean in __sync_icache_dcache()"). Verified with added instrumentation to track dcache flushes in a ring buffer, as shown by the (distilled) output: kernel: SIGILL at b6b80ac0 cpu 1 pid 32663 linux_pte=8eff659f hw_pte=8eff6e7e young=1 exec=1 kernel: dcache flush START cpu0 pfn=8eff6 ts=48629557020154 kernel: dcache flush SKIPPED cpu1 pfn=8eff6 ts=48629557020154 kernel: dcache flush FINISH cpu0 pfn=8eff6 ts=48629557036154 audisp-syslog: comm="journalctl" exe="/usr/bin/journalctl" sig=4 [...] Discussions in the mailing list mentioned that arch/arm is also affected but the fix was never applied to it [1][2]. Apply the change now, since the race condition can cause sporadic SIGILL's and SEGV's especially while under high memory pressure.

net: remove unused ATM protocols and legacy ATM device drivers

2026-04-23T19:21:14+00:00

Remove the ATM protocol modules and PCI/SBUS ATM device drivers that are no longer in active use. The ATM core protocol stack, PPPoATM, BR2684, and USB DSL modem drivers (drivers/usb/atm/) are retained in-tree to maintain PPP over ATM (PPPoA) and PPPoE-over-BR2684 support for DSL connections. The Solos ADSL2+ PCI driver is also retained. Removed ATM protocol modules: - net/atm/clip.c - Classical IP over ATM (RFC 2225) - net/atm/lec.c - LAN Emulation Client (LANE) - net/atm/mpc.c, mpoa_caches.c, mpoa_proc.c - Multi-Protocol Over ATM Removed PCI/SBUS ATM device drivers (drivers/atm/): - adummy, atmtcp - software/testing ATM devices - eni - Efficient Networks ENI155P (OC-3, ~1995) - fore200e - FORE Systems 200E PCI/SBUS (OC-3, ~1999) - he - ForeRunner HE (OC-3/OC-12, ~2000) - idt77105 - IDT 77105 25 Mbps ATM PHY - idt77252 - IDT 77252 NICStAR II (OC-3, ~2000) - iphase - Interphase ATM PCI (OC-3/DS3/E3) - lanai - Efficient Networks Speedstream 3010 - nicstar - IDT 77201 NICStAR (155/25 Mbps, ~1999) - suni - PMC S/UNI SONET PHY library Also clean up references in: - net/bridge/ - remove ATM LANE hook (br_fdb_test_addr_hook, br_fdb_test_addr) - net/core/dev.c - remove br_fdb_test_addr_hook export - defconfig files - remove ATM driver config options The removed code is moved to an out-of-tree module package (mod-orphan).

caif: remove CAIF NETWORK LAYER

2026-04-23T17:23:44+00:00

Remove CAIF (Communication CPU to Application CPU Interface), the ST-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 officially shut 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, and the 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 were 3 reports on security@ about CAIF that I have been CCed on. UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the SELinux classmap entry are intentionally kept for ABI stability. Acked-by: Michael S.

ARM: dts: bcm4709: fix bus range assignment

2026-04-20T15:03:36+00:00

The netgear r8000 dts file limits the bus range for the first host bridge to exclude bus 0, but the two devices on the first bus are explicitly assigned to bus 0, causing a build time warning: /home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@1,0:bus-range: PCI bus number 0 out of range, expected (1 - 255) /home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@2,0:bus-range: PCI bus number 0 out of range, expected (1 - 255) As Rosen mentioned, the bus-range property was a mistake, so just remove it and keep the reg values pointing to bus 0, which is allowed by the default bus range of the SoC.
