I'm sorry, I tried 4.16.0-rc2 when I got to physically access the server in the PoC cluster this morning, but the driver called "hpsa" for the RAID controller didn't work in the boot-up phase, I guess it could've possibly been because of the failed hard disk drive in the array of RAID 1. I had to roll back to 4.13.0 that comes with the HWE package in Ubuntu 16.04, but I'd like to try to run the new kernel and see if it does fix the problem so I'm going to do it on my laptop this weekend.
Regards, Gunwoo -- 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/1749058 Title: incorrect source address in IGMP Membership Report messages Status in linux package in Ubuntu: Incomplete Bug description: I found that linux kernel had had a bug in the implementation of IGMP membership report packet generation. the RFC documents for IGMP version 2 and 3 says that you must ignore the reports with a source ip address that you can't identify as belonging to a network assigned to the interface on which the packet was received. and the networking OS in the ToR switch, Force10 OS 9 does ignore it. I've also figured out a patch has been made for this bug in Linus's Github. and there was a mark on Github that reads "v4.16-rc1". ( https://github.com/torvalds/linux/commit/a46182b00290839fa3fa159d54fd3237bd8669f0 ) I honestly have no idea how Ubuntu LTS team works with regard to this kind of patches from the fresh new upstream version of linux kernel. hope you guys will easily fix it for people like me who has no experience at building and distributing custom built kernels over a few servers. Test environment: I used two ToR switches and one linux machine for this test. I only used 2 ethernet ports on the linux machine. There was a recent version of Ubuntu with HWE kernel. I'm not sure if no-HWE one would be the same case - the version of linux-generic-hwe-16.04 was 4.13.0.32.52 - To test networking router stuff, I used the quagga from Cumulus Routing on the Host 3.3.2 ( https://cumulusnetworks.com/products/cumulus-routing-on-the-host/#roh-download-section ) What I did and saw in my case: 1. set a network interface (A) so it gets an IPv4 address, but also in vain issue "ip link set ${if_name} multicast off" 2. assign an IPv4 address to another network interface (B), but in this case with a 31-bit-long subnet mask length. 3. install quagga from cumulus, launch zebra and pimd, issue "ip pim sm" in the interface configuration mode for the interface (B) with a 31-bit-long subnet mask length 4. I checked that the source IP address part of the IGMP membership report packets from the linux machine is the address I assigned to the network interface (A) with 27-bit-long subnet mask -using dumpcap and tshark-, and that the PIM service on the switch ignored the Reports printing debugging messages including : "Invalid sender address" affects ubuntu Regards, Gunwoo -- You can find my PGP public key here: https://google.com/+DewrKim/about --- AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Feb 12 15:36 seq crw-rw---- 1 root audio 116, 33 Feb 12 15:36 timer AplayDevices: Error: [Errno 2] No such file or directory ApportVersion: 2.20.1-0ubuntu2.15 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=/dev/mapper/peta--0001--01--vg-swap_1 InstallationDate: Installed on 2017-07-05 (223 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) IwConfig: Error: [Errno 2] No such file or directory MachineType: HP ProLiant DL360 G6 Package: linux (not installed) PciMultimedia: ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.13.0-32-generic root=/dev/mapper/peta--0001--01--vg-root ro isolcpus=4,8,12,16,20,24,28,6,10,14,18,22,26,30 hugepagesz=1G hugepages=0 hugepagesz=2M hugepages=2048 ProcVersionSignature: Ubuntu 4.13.0-32.35~16.04.1-generic 4.13.13 RelatedPackageVersions: linux-restricted-modules-4.13.0-32-generic N/A linux-backports-modules-4.13.0-32-generic N/A linux-firmware 1.157.14 RfKill: Error: [Errno 2] No such file or directory Tags: xenial xenial Uname: Linux 4.13.0-32-generic x86_64 UnreportableReason: The report belongs to a package that is not installed.
