Description: dhcpcd does not set an ip, logs show the
following error:
dhcpcd[]: enp1s0: checksum failure from 173.23.0.1 Additional info: * 9.0.2-1 (in ArchISO 202005, not affected * DHCP server: dnsmasq 2.81-4 Steps to reproduce: - QEMU/KVM setup which connects a vm to the host system through a bridge interface. - vm booting the ArchISO 202005, dhcpcd 9.0.2-1 - no ipv4 address set, and the followin errors in the logs: dhcpcd[]: enp1s0: checksum failure from 173.23.0.1 dhcpcd[]: enp1s0: timeout dhcpcd[]: dhcpcd exited Steps which do work as expexted: - QEMU/KVM setup which connects a vm to the host system through a bridge interface. - vm booting the ArchISO 202004, dhcpcd 8.1.6-1 - interface has an ipv4 address set - Manual starting gives the same errors in the logs; systemctl start dhcpcd@enp1s0 I have create a pcap dump of the bridge interface of ArchISO's and appears the dhcp server is sending a DHCP Offer in both scenarios. I have attached both pcap files. Found some older bug reports with the same error, where this issue appears to be related to the used gcc version and optimizations settings used [1].

I think you can mark this bug as resolved and close it.
If I'm not mistaken, the ISO comes with 9.0.2. When you pacstrap, you will obviously get the latest version. I'll close this anyway.
