218633 - No OpenBSD support for IPv6

Status: RESOLVED FIXED

(NSPR :: NSPR, defect)

Description

[Paul de Weerd]

User-Agent:       Mozilla/5.0 (X11; U; OpenBSD i386; en-US; rv:1.5a) Gecko/20030908 Mozilla Firebird/0.6.1
Build Identifier: Mozilla/5.0 (X11; U; OpenBSD i386; en-US; rv:1.5a) Gecko/20030908 Mozilla Firebird/0.6.1

When trying to connect to a website with an IPv6 address (such as
http://www.kame.net/ , http://www.ipng.nl/ or http://www.sixxs.net/ ) firebird
refuses to connect over IPv6 and uses IPv4 instead. For sites that do not have
an IPv4 address firebird can not connect at all.

I noticed that Firebird does not even resolve quad-A records (IN AAAA) for
hostnames entered as URLs. However, Firebird also does not connect when given
the IP address explicitly (within []'s) and instead appears to search the web
for a page containing the given URL (go to http://[2001:6e0::250:4ff:fe4a:7708]/
for an example)

Reproducible: Always

Steps to Reproduce:
1. Install the latest OpenBSD snapshot
2. Install the mozilla-firebird port using the portstree
3. Open firebird and visit an IPv6-enabled website such as http://www.kame.net/

Actual Results:  
Firebird connects over IPv4 (to 203.178.141.194)

Expected Results:  
Firebird should connect over IPv6 (to 2001:200:0:8002:203:47ff:fea5:3085). On
http://www.kame.net/ a 'dancing kame' should be shown in stead of the static
kame you see when connecting over IPv4.

[Mike Connor [:mconnor]]

spoke to timeless on IRC, there may not even be any IPv6 code for OpenBSD in
Mozilla.

Darin, could you take care of this?  I suspect you can
use the code in pr/include/md/{_freebsd.h,_netbsd.h} as
an example for _openbsd.h.

I have just installed Firebird 0.7 on my system. Unfortunately there's still no
IPv6 support.

Comment 4

[Paul de Weerd]

Today I upgraded two workstations to the latest -current version of OpenBSD. I 
also installed all ports again, upgrading firebird to an unofficial firefox 
port. Unfortunately firefox also does not allow me to visit IPv6-enabled 
websites. Still no AAAA records are queried for hosts I want to visit.

I'm hoping for 1.0 ;)

Comment 5

[Wan-Teh Chang]

We added code to enable IPv6 support in NSPR for
OpenBSD on 2004-03-10.

Could someone test IPv6 with a Mozilla nightly build
dated 2004-03-11 or later, or Mozilla 1.7 beta or
later on OpenBSD?

Comment 6

The following diff (as found in a posting from Waldemar Brodkorb to the OpenBSD
ports mailinglist; see
http://marc.theaimsgroup.com/?l=openbsd-ports&m=107775193605517&w=2 for his
posting) fixes the issue with firefox 0.8. That is to say, with this patch I can
connect to IPv6 sites and everything appears to function correctly (have not
found any problems yet).

I hope this can be integrated in the source.

Paul: thank you for pointing out the patch and
verifying that it works.

That patch is exactly the new code I mentioned
(in comment 5).  So I am marking this bug fixed.
That patch will be in Mozilla 1.7 beta.  I don't
know when it will appear in Firefox because I
don't follow Firefox development.
