dhcpc: ps_root_recvmsg: Permission denied

Hi,

I am using net/dhcpcd on OpenBSD 7.3 for IPv6 router solicitation over
PPPoE, almost identical to the setup as described in
/usr/local/share/doc/pkg-readmes/dhcpcd.

Everything works (i.e., IPv6 connectivity and distributing prefixes) but
I have a lot of log messages complaining about:

# tail /var/log/messages

Aug 9 15:55:43 fw dhcpcd[57551]: ps_root_recvmsg: Permission denied

The function ps_root_recvmsg appears in
https://github.com/NetworkConfiguration/dhcpcd/blob/master/src/privsep-root.c
which is about privilege separation but I have not found out the cause
yet.

Anyone else seeing this? Any ideas to fix this?

Thank you!

Best regards,
Ingo
