dhcpcd-discuss

Hi Roy,

9.1.0 and master (bf6dd06) with privsep on OpenBSD don't pick up
the vlan id when trying to pick an IAID, so it uses the partial MAC
address resulting in conflicts. (The addresses do end up configured
ok though).

Config is:

ipv6only
noipv6rs
duid
persistent
option rapid_commit
require dhcp_server_identifier
nohook resolv.conf, lookup-hostname
allowinterfaces pppoe1 vlan2 vlan9 vlan5 vlan3

interface pppoe1
  ia_pd 2 vlan2/1 vlan9/2 vlan5/3 vlan3/4

Also with master (but not 9.1.0) I get some EBADF from the new
ps_root_startcb debug logs. It does otherwise work similar to 9.1.0
and configure the addresses ok.

Output from dhcpcd -d below, first 9.1.0, then head, then 9.0.2 for
comparison.
