-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1989187 Title: 5.4: Setting net.ipv4.conf.<interface>.arp_notify=1 does not generate gratuitous ARPs Status in linux package in Ubuntu: Incomplete Bug description: Expected behaviour: The kernel should send out a gratuitous ARP on the interface when the following commands are executed: $ sudo sysctl -w net.ipv4.conf.eth0.arp_notify=1 net.ipv4.conf.eth0.arp_notify = 1 $ sudo ip link set dev eth0 down $ sudo ip link set dev eth0 up Result: The gratuitous ARP packet is generated inside the kernel (inetdev_send_gratuitous_arp() is called) but the packet is never sent out on the interface. Generating gratuitous ARP packets with "arping" works however. --- ProblemType: Bug AlsaDevices: Error: command ['ls', '-l', '/dev/snd/'] failed with exit code 2: ls: cannot access '/dev/snd/': No such file or directory AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.11-0ubuntu27.24 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' CRDA: N/A CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lsusb: Error: command ['lsusb'] failed with exit code 1: Lsusb-t: Error: command ['lsusb', '-t'] failed with exit code 1: /sys/bus/usb/devices: No such file or directory Lsusb-v: Error: command ['lsusb', '-v'] failed with exit code 1: MachineType: QEMU Standard PC (Q35 + ICH9, 2009) Package: linux (not installed) PciMultimedia: ProcEnviron: TERM=screen PATH=(custom, no user) LANG=C.UTF-8 ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-1074-kvm root=PARTUUID=88d3c80a-b7b6-4782-8531-3699e254fb95 ro console=tty1 console=ttyS0 panic=-1 ProcVersionSignature: Ubuntu 5.4.0-1074.79-kvm 5.4.195 RelatedPackageVersions: linux-restricted-modules-5.4.0-1074-kvm N/A linux-backports-modules-5.4.0-1074-kvm N/A linux-firmware N/A RfKill: Error: [Errno 2] No such file or directory: 'rfkill' Tags: focal uec-images Uname: Linux 5.4.0-1074-kvm x86_64 UnreportableReason: This report is about a package that is not installed.
