Hi all,

Sorry about the mixing of topics. I will repost the SSL question when I am
done investigating the DNS topic which currently is the deal breaker :)
I did some DNS packet sniffing and it seems the problem is that haproxy
does a type=ANY request to DNS for the domain names, and weave-DNS then

Hi all,
I have a HAproxy 1.5 setup which offloads SSL in front of multiple webservers.
My SSL certificate is a wildcard and we are balancing to different backends
based on the FQDN.
My frontend config look like this :

frontend my-frontend

My config is fairly complex, but let me see what I can do. And actually, I do
use two certs on the same line, but this was never a problem with 1.5.*

So you may be right on the two certs on the same line bug. Just removed one of
the certs and so far, so good. Can you verify?

Are both or one of them (first or second one) wildcard certificates?
Thanks,

One of them is, but I just removed the one that is not a wildcard and all

Hey guys,
by default, HAProxy tries to resolve server IPs using an ANY query
type, then fails over to resolve-prefer type, then to "remaining"
type.
So ANY -> A -> or ANY -> -> A.
In some cases, ANY query type is ignored or response contains no
records, which leads HAProxy to try next q
Hey Baptiste,
Using ANY queries for this kind of stuff is considered by most people to
be a bad practice since besides all the things you named it can lead to
incomplete responses. Basically a resolver is allowed to just return
whatever it has in cache when it receives an ANY query instead of
Actually, I just asked one of the powerdns devs, and their
recursor/resolver implementation does actually only return what is in
its cache when answering an ANY query.

Hi,
Here is a proper patch to fix the recent bug reported on haproxy 1.6.0
when SNI is used.
Willy, I didn't wait your reply to speed-up the code review. But if
there is any problem with this patch, let me know.

We can't really rely on ANY queries, no. Also see [1], [2].

I second this opinion. Removing ANY altogether would be the best case.
In reality, I think it should use the OS's resolver libraries which
in turn will honor whatever the admin has configured for preference
order at the base OS level.
As a sysadmin, one should reasonably expect that tweaking

Hi.
I can confirm this fixes the crash / segfault when running the ssllabs
tests against my HAProxy instance :)
Now we are happily running a 1.6.0 frontend for our Docker / Swarm cluster !!
