Okay, I've installed CURRENT again for testing (the 19 August
snapshot). This problem does not occur in 3.7-STABLE. Below is a
script of the behavior using a laptop, a wi(4) card, and a Linksys
BEFW11S4 ver. 2 "Wireless Access Point and Cable/DSL Router with
4-port switch". The raw tcpdump is available for download at
http://www.aleph0.com/computing/machines/dave/OpenBSD-3.8-dhcp-bug-tcpdump
If there's any concern about what I expect to see (instead of what I
did see), or any other information I can provide which might be
helpful, please let me know.
Question: should I go ahead and submit an official problem report, or
just expect to talk about it here?
Final note: This is with a wireless card, since that's the only thing
convenient to test with, but I have an almost identical problem with
onboard ethernet and DHCP: the output of dhclient looks like (copied
by hand):
DHCPDISCOVER on sis0 to 255.255.255.255 port 67 interval 3
ip length 576 disagrees with bytes received 580.
accepting packet with data after udp payload.
DHCPOFFER from 192.168.1.1
DHCPREQUEST on sis0 to 255.255.255.255 port 67
ip length 576 disagrees with bytes received 580.
accepting packet with data after udp payload.
Discarding packet with invalid hlen.
[repeat ad infinitum]
Okay, onto the full script (using wi(4)):
