Title:
systemd-networkd fails to renew DHCP v4 lease when renew attempt times
out
Status in systemd package in Ubuntu:
Confirmed
Bug description:
I'm seeing exactly what this gist describes:
https://gist.github.com/raggi/1f8d0b9f45c5b62e7131b03e6e2ffe68
Summary:
1. Configure a machine with a DHCPv4 lease on a network with a DHCPv4 server.
2. Place machine under unusual load sufficient to cause a timeout on netlink
requests.
3. Observe the interface failing with the following logs:
systemd-networkd[139370]: eth0: Could not set DHCPv4 address: Connection
timed out
systemd-networkd[139370]: eth0: Failed
The error seems to come from here:
https://github.com/systemd/systemd/blob/v245.4/src/network/networkd-dhcp4.c#L781
Expected behavior
The DHCPv4 client should retry the lease refresh when the issue is a timeout,
eventually succeeding in these scenarios.
Actual behavior
Permanent loss of connectivity on the affected interface.
