[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver
Just talked to a SuperMicro tech agent and has sent me a non released BIOS update for the X9DRI-4LNF motherboard, which fixes Spectre and several other fixes, including the enumeration problem of the ethernet jacks of this board. This BIOS update is v3.3 and dated from May 2018, so pretty recent, but as the board is EOL there won't be any further updates and this one will be the most up to date. You can find the BIOS update file here: https://drive.google.com/open?id=1PfWZXd-0DWuJ6MJh4OneeHdD1FLFXmx8 In case you don't trust me, please ask the SM tech guy to send you the latest BIOS update, in my case it was "x9dr3p8.523.zip" -- 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/1578141 Title: Predictable interface names partially broken with igb driver Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: Note: I'm not sure whether this is really a kernel bug or something within systemd/udev, please advise how to further debug.

[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver
quick update, fwiw I just got an updated bios from a SM tech and it worked: $ sudo biosdevname -d | grep "BIOS dev" BIOS device: em1 BIOS device: em2 BIOS device: em3 BIOS device: em4 The bios's reported version from the BIOS screen is 3.2, which @pdxvoyd said he had problems with, but I guess for me it's the complete opposite since I had probs on 3.0 which he said worked for him and 3.2 fixes it for me which didn't work for him. In any case something should probably happen with systemd to handle clashing names because these are servers, not desktop boxes, and automation is pretty much impossible if network interfaces fail to come back. best, Spike -- 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/1578141 Title: Predictable interface names partially broken with igb driver Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: Note: I'm not sure whether this is really a kernel bug or something within systemd/udev, please advise how to further debug.

Dear all, I have a supermicro X9DRI-4LNF and experiencing the same issue. @pdxvoyd mentioned this does not happen on BIOS 3.0 but it does for us. Running latest xenial server with kernel 4.4.0-66. sudo biosdevname -d | grep device BIOS device: em1 BIOS device: em1 BIOS device: em1 BIOS device: em1 So confirming the problem with conflicting info coming from the BIOS. @pdxvoyd any news on your report to SM? been 8 months since your comment.

[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver
I recently ran into this while upgrading 76 systems. In my research I have concluded that this bug is the result of bad information coming from the BIOS 3.0b, 3.0c, and 3.2. This bug is not present with BIOS 3.00. If you run biosdevname, you will see that the BIOS Device name is em1 for both of the intel i350 interfaces resulting (as mentioned above by Dr. Jens Rosenboom (j-rosenboom-j) in dracut successfully naming the first device to initialize as eno1. If you reboot the system and check udevadm, you can see that the interfaces can alternate in which port is initialized first resulting in eno1 moving from port1 to port2. This is causing problems primarily with bonding our interfaces. sudo biosdevname -d BIOS device: em1 Kernel name: eno1 Permanent MAC: 00:00:00:00:00:00 Assigned MAC : 00:00:00:00:00:00 ifIndex: 2 Driver: igb Driver version: 5.2.15-k Firmware version: 1.61, 0x890e Bus Info: :06:00.0 PCI name : :06:00.0 PCI Slot : embedded SMBIOS Device Type: Ethernet SMBIOS Instance: 1 SMBIOS Label: Onboard Intel Ethernet 1 sysfs Index: 1 sysfs Label: Onboard Intel Ethernet 1 Embedded Index: 1 Duplicate: True BIOS device: em1 Kernel name: eth1 Permanent MAC: 00:00:00:00:00:00 Assigned MAC : 00:00:00:00:00:00 ifIndex: 3 Driver: igb Driver version: 5.2.15-k Firmware version: 1.61, 0x890e Bus Info: :06:00.1 PCI name : :06:00.1 PCI Slot : embedded SMBIOS Device Type: Ethernet SMBIOS Instance: 1 SMBIOS Label: Onboard Intel Ethernet 2 sysfs Index: 1 sysfs Label: Onboard Intel Ethernet 2 Embedded Index: 2 Duplicate: True I have submitted my findings for all of my nodes to Supermicro seeking a bug fix and releasing an update BIOS. -- 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/1578141 Title: Predictable interface names partially broken with igb driver Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: New Bug description: Note: I'm not sure whether this is really a kernel bug or something within systemd/udev, please advise how to further debug.

[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver
@Martin: Fixing the installed system is easy, the bad case happens when the installer sets up the system with "rename2" as the first interface, making access via console necessary in order to recover. root@compute-node37:~# SYSTEMD_LOG_LEVEL=debug udevadm test-builtin net_id /sys/class/net/eno1 calling: test-builtin === trie on-disk === tool version: 229 file size: 6841778 bytes header size 80 bytes strings1755242 bytes nodes 5086456 bytes Load module index timestamp of '/etc/systemd/network' changed timestamp of '/lib/systemd/network' changed Parsed configuration file /lib/systemd/network/99-default.link Parsed configuration file /lib/systemd/network/90-mac-for-usb.link Created link configuration context.

Also note that the whole renaming process seems to come from an Ubuntu specific patch in Revert-udev-network-device-renaming-immediately- give.patch, IIUC plain systemd would fail the renaming process and end up with either (eno1, eth1) or (eth0, eno1) as interface tuples.

[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver
Looking further, it seems that the BIOS is providing broken information, see this snippet from dmidecode output: Handle 0x007E, DMI type 41, 11 bytes Onboard Device Reference Designation: Onboard Intel Ethernet 1 Type: Ethernet Status: Enabled Type Instance: 1 Bus Address: :07:00.0 Handle 0x007F, DMI type 41, 11 bytes Onboard Device Reference Designation: Onboard Intel Ethernet 2 Type: Ethernet Status: Enabled Type Instance: 1 Bus Address: :07:00.1 and as a result we get ID_NET_NAME_ONBOARD=eno1 for both devices. So udev tries to rename both interfaces to eno1, only one succeeds, the other one fails due to a name collision.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc6-wily/ ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1578141 Title: Predictable interface names partially broken with igb driver Status in linux package in Ubuntu: Incomplete Bug description: Note: I'm not sure whether this is really a kernel bug or something within systemd/udev, please advise how to further debug. On a system with two GE ports, instead of getting named eno1 and eno2, I am getting eno1 and renameN. Where N starts at 3 and increases by 2 on every iteration of doing "rmmod igb;modprobe igb". The corresponding lines in dmesg look like this: [2.748429] igb :07:00.0: added PHC on eth0 [2.748431] igb :07:00.0: Intel(R) Gigabit Ethernet Network Connection [2.748433] igb :07:00.0: eth0: (PCIe:5.0Gb/s:Width x4) 00:25:90:d7:60:8e [2.748505] igb :07:00.0: eth0: PBA No: 106100-000 [2.748506] igb :07:00.0: Using MSI-X interrupts. 8 rx queue(s), 8 tx queue(s) [2.802555] igb :07:00.1: added PHC on eth1 [2.802557] igb :07:00.1: Intel(R) Gigabit Ethernet Network Connection [2.802559] igb :07:00.1: eth1: (PCIe:5.0Gb/s:Width x4) 00:25:90:d7:60:8f [2.802631] igb :07:00.1: eth1: PBA No: 106100-000 [2.802632] igb :07:00.1: Using MSI-X interrupts. 8 rx queue(s), 8 tx queue(s) [2.803618] igb :07:00.0 eno1: renamed from eth0 [2.833208] igb :07:00.1 rename3: renamed from eth1 What is even worse: Sometimes the naming changes and the second interface ends up as eno1 while the first interface is named renameN with an even N. The bad thing about this version is that when it happens while the installer is running, the installer will setup "rename2" as the primary network interface, which works fine for the installation itself, but after installation is finished and the first boot of the installed system happens, that interface will be gone, leaving the system without network connectivity.
