Package: udev Version: 240-1 Severity: important After upgrading from 239-15 to 240-1 or higher my network setup breaks.
The breakage is similar to the last one I reported (bug #904198) though different in detail. This times all my vlan-devices on a physical device netint are first renamed to renameX and than udev tries to rename them again but this time it tries to give them all the name netint - which of course fails. A setup like the following one should be able to reproduce this problem: 10-netint.link: [Match] MACAddress=00:01:2e:77:a5:45 [Link] Name=netint WakeOnLan=off netint.network: [Match] Name=netint [Network] VLAN=kbs LinkLocalAddressing=no DHCP=no kbs.link [NetDev] Name=kbs Kind=vlan [VLAN] Id=10 In the journal you should see something like kernel: rename31: renamed from kbs .... systemd-networkd[852]: kbs: Interface name change detected, kbs has been renamed to rename31 .... [347]: kbs: Failed to rename network interface 31 from 'kbs' to 'netint': Device or resource busy .... Downgrading udev to 239-15 fixes it in principle that is this rename does not happen. systemd-networkd from 240-1 though crashes with Assertion 'IN_SET(link->state, LINK_STATE_CONFIGURING, LINK_STATE_CONFIGURING, LINK_STATE_FAILED, LINK_STATE_LINGER)' failed at ../src/network/network/networkd-link.c:934, function address_handler(). Aborting. Therefor I also had to downgrade systemd back to 239-15. Regards, -- Wolfgang Walter Studentenwerk München Anstalt des öffentlichen Rechts
