Hello,
I'm receiving this error after upgrading from dhcpcd 9.0.2 to 9.1.4
on OpenBSD-current. The result of which is that I no longer receive
IPv6 addresses on any interfaces.
dhcpcd_fork_cb truncated read 0 (expected 4)
ps_ctl_listen: read: Undefined error: 0
em0 is my external interface and em1 assigned to be the internal
interface. I am using dhcpcd for IPv6-PD with rad providing a /64
to my internal LAN.
/etc/dhcpcd.conf:

Using the default configuration file does yield an IPv6 address on
em0. Looking at the differences between mine and the default,
the PD config is the only obvious one.
Let me know if additional information to properly troubleshoot is
required
Best,
Lucas
