Hi, 'dhcpcd 8.1.1' is out. => https://roy.marples.name/archives/dhcpcd-discuss/0002641.html "dhcpcd-8.1.1 has been released with the following changes: * IPv6: Fix a potential crash when udevs marks an interface ready. * Linux: compat shim added for setproctitle(3). * arc4random: fixed UB in compat shim. * DHCP: Fix fallout from dhcpcd-8.1.0 for checksum calculation. The last fix involved a lot a people, quite a few different fixes and played havoc with gcc-9.2 but should now be resolved." I'm working on it. Best, Matthias
