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
