does OpenBSD not like a RR with TTL set to 0? this is the first time I've run into this, and I had to put the stupid lounge captive portal in /etc/hosts to make it work

if I dig or nslookup or host, I get the response. if I ping, I get hostname does not exist and the pcaps show four attempts (and responses!) at querying domain.name then it tries domain.name.hostname.local and stops.

I guess a long read starting with gethostbyname(3) is in order?

is there some way to *detect* a Spectre or Meltdown-like attack attempt from *within* the guest VM?

that would be so, so, SO valuable to me.

I'm also looking to use/rent-by-the-hour two servers with Intel 82599-based 10GbE NICs in them for this.

if you or someone you know can loan the use of such machines for two or three days so I can run tests and generate data for my talk, I'd be eternally grateful and delighted to give you/$corp/other a shoutout in my talk!

(boosts also appreciated)

Taking a break from preparing for my talk tomorrow on P4 to focus on my #eurobsdcon talk on packet processing in the BSDs, and their packet filters.

Generating call graphs and profilling data from C/C++ source is proving *sliiiiightly* more difficult than I had anticipated. ...and I anticipated some difficulty.

I'm working with cscope and cflow, but would greatly appreciate suggestions, referrals, ideas, and boosts for additional resources.
