Description

Upgrading works fine, router comes up good on the first boot. Any reboots after that and the networking config is messed up.

Snippet from config.boot pre-upgrade:

First boot into 1.3. Networking is OK:

Snippet from config.boot, clearly some syntax has changed:

Rebooting again, not making any changes, committing or saving ends up with broken networking:

And config.boot has been messed up. Notice the double hw-id's and added eth0.

Why is there no eth0 on VyOS 1.2.5?

I tried mocking with your configuration and thus needed to delete the policy statement as I have no policy installed. Maybe you can boot your system with the vyos-config-debug option and share the output? Or send the full config.boot.

To pass the parameter, halt on GRUB prompt, press e for edit and change as follows, then press F10 to boot

I've manually edited config.boot to have eth1->4 instead of eth0->3 to correctly reflect the interface naming of the appliance.
Should I run the debug during first-boot, second boot, or maybe both?

Why 2 times hw-id for eth1 eth2 eth3

ethernet eth1 {
    address "dhcp"
    duplex "auto"
    hw-id "00:e0:67:16:d8:ac"
    smp-affinity "auto"
    speed "auto"
    hw-id 00:e0:67:16:d8:ad

VyOS added those during the 2nd boot after upgrade. I would assume bug related to the fact that my config doesn't include eth0.

pasik subscribed.May 27 2020, 5:13 PM

Reworking my config so that it uses eth0->eth3 instead of eth1->eth4 makes everything work as expected. So something has clearly changed regarding the interface naming/creation logic.

Yes there have been issues with interface naming in the past. Hopefully they are finally resolved in 1.3 now.

Closing this. Please reopen if problem happens again

I think I ran into this today after upgrading from 1.3-rolling-202006110117 to 1.3-rolling-202006241940. My config had eth1-eth3 (as those were the default names created by a previous install of 1.3 somewhere around May) and those worked fine for numerous reboots before this upgrade. The first reboot after adding the new image, everything was fine. The 2nd reboot (actually a power outage) the interfaces were eth0-eth2 on the system, but eth1-eth3 in the config, so the config load failed.

This is after entering config mode and loading config.boot:

vyos@vyos# show interfaces 
 ethernet eth0 {
     hw-id xx:b4
 }
 ethernet eth1 {
     address dhcp
     address dhcpv6
     hw-id xx:b5
     ipv6 {
         address {
             autoconf
         }
     }
 }
 ethernet eth2 {
     hw-id xx:b6
 }
+ethernet eth3 {
+    hw-id xx:b6
+}
 loopback lo {
 }
[edit]

As can be seen, eth3 should be :b6 but eth2 has that mac, so all interfaces were shifted by one (:b4 was eth1 in config.boot, :b5 eth2, :b6 eth3)

Not doing anything regarding the failed load and just rebooting has now hard-baked the eth0-eth2 names into config.boot without me doing anything. So something effectively decided to rename eth1-eth3 to eth0-eth2 and save it to config.boot.

Attached are config.boot post-upgrade(migration) and config.boot pre-migration.
Notice:

doubled hw-id lines
missing opening and closing curly braces on lines 45, 75-77 (tag nodes)
lines 8, 33, 35 are leaf nodes, those shouldn't have opening/closing curly braces after them
some things are quoted, some are not

Maybe the wrong curly braces or the wrong quoting introduced by the migration scripts confuses the config system?

This comment was removed by jjakob.

Migration scripts use vyos.configtree which uses libvyosconfig so it's probably a bug there.

Edit: or not, as I've hand edited config.boot to fix all the braces (none on valueless nodes, present on tag nodes), rebooted, and the doubled hw-id lines reappeared, as did the wrong braces, undoing all my changes. Since no migrations scripts were ran (no config.boot.pre-migration with the current date) it's likely not a bug there, but in vyatta-cfg, or something causes a bug in vyatta-cfg to appear.

c-po mentioned this in rVYOSONEX92c206809ced: migration: interfaces: T2523: fix pseudo-ethernet migration.Jun 26 2020, 4:28 PM

Sorry - used the wrong task

To clarify, I'm not actually sure the formatting is the reason for the bug - I just observed that it happened. It may have no impact on functionality. The real problem is that something is messing with the hw-id entries, and I don't think it's the migrator scripts, as those weren't executed when it happened. Maybe some legacy Vyatta code.

I tried reupgrading from 1.3-rolling-202006110117 to 1.3-rolling-202007050117 and the exact same error occurred - on first reboot everything was fine (config.boot was migrated, looked correct, and loaded fine). On 2nd reboot, the exact same thing happened.

Upgrading a different test VM with different config that starts at eth0: on 2nd reboot the hw-id lines are duplicated too, but they are the same on a single interface, and there are no new interfaces created, so the config loads and works fine. The duplicated hw-id lines stay in the config for all subsequent reboots.
Example:

ethernet eth0 {
    address "192.0.2.1"
    hw-id "52:54:00:2d:29:19"
    ipv6 {
        address {
        }
    }
    smp-affinity "auto"
    speed "auto"
    hw-id 52:54:00:2d:29:19
}

What I'm noticing is that the migration scripts save all nodes with quotes, but saving in config mode (through vyatta-cfg) results in most nodes not having quotes (mostly just those with spaces have it). Maybe there is a vyatta script that adds any new interfaces to config.boot that runs on each boot that doesn't like these quoted hw-id lines that the migration scripts produce.

The most likely culprit is /opt/vyatta/sbin/vyatta_interface_rescan. I'm not sure if this should be fixed or migrated to Python.
The rewrite would need to be done together with all other vyatta interface renaming and detection scripts.

Could you please try the latest 1.3 beta version or 1.4 rolling from https://downloads.vyos.io ?
