[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[thedarkwinter]

Also, once I have installed the update on the DNS server, if I run apt-
get update it queries TYPE62321 record.

22-Mar-2017 06:04:37.406 queries: info: client 127.0.0.1#38103
(gb.archive.ubuntu.com.comlaude.lon2): query:
gb.archive.ubuntu.com.comlaude.lon2 IN TYPE62321 + (127.0.0.1)

This server is also an apt-cacher server, if i restart apt-cacher, then
it queries A records correctly again.

22-Mar-2017 06:05:37.426 queries: info: client 127.0.0.1#52629
(gb.archive.ubuntu.com): query: gb.archive.ubuntu.com IN A + (127.0.0.1)

Again, the question is what else needs to be restarted?

[Adam Conrad]

Yes, it's known that updating from the version with the regression to
the version that backed it out will cause the same (well, inverse) bug
to appear until services or the machine are restarted.  That's
unfortunate, but there's not a whole bunch we can do to mitigate that,
and reverting the regression was the important bit.

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[thedarkwinter]

To add to that, I just manually updated another running webserver, and
boom. The apache+php webserver uses DNS to resolve the database server,
which it can no longer do after the update, bringing the site down.

It sends these incorrect TYPE62321 DNS queries to our DNS server.

22-Mar-2017 05:33:01.205 queries: info: client 172.16.x.x#59821
(mysql.internal.domain): query: mysql.internal.domain IN TYPE62321 +
(172.16.x.x)

In this case, restarting apache2 clears the issue. I don't know if
anything else also needs restarting (so i did a reboot after to be
sure).

If it helps, I also have traditional resolv.conf instead of resolvconf

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[thedarkwinter]

Just like my earlier comment, this _fix_ *broke* a running system after
it was automatically applied.

Start-Date: 2017-03-22  04:17:12
Commandline: /usr/bin/unattended-upgrade
Upgrade: libc6:amd64 (2.23-0ubuntu6, 2.23-0ubuntu7), locales:amd64 
(2.23-0ubuntu6, 2.23-0ubuntu7), libc-bin:amd64 (2.23-0ubuntu6, 2.23-0ubuntu7), 
multiarch-support:amd64 (2.23-0ubuntu6, 2.23-0ubuntu7)
End-Date: 2017-03-22  04:17:34

Immediately after that, the system is no longer able to resolve names.
On my DNS server, I can see this is sending queries of TYPE62321 instead
of A

22-Mar-2017 04:17:30.407 queries: info: client 172.16.x.x#63762
(host.interna.domain): query: host.interna.domain IN TYPE62321 +
(172.16.1.10)

A reboot clears the issue, but the point is that applying the update is
still a "critical" bug because it breaks [some] running systems. In this
case, the system is running apache+php. It might be that it only effects
certain things.

The libc6-udeb_2.19-0ubuntu6.11_amd64.udeb fix that was just released
fixes the name resolution issues and we're able to provision our systems
as normal again.

is it valid to run the broken install, when it breaks manually pull down

Hi, I've put test glibc packages in the ubuntu-security-proposed ppa
https://launchpad.net/~ubuntu-security-
proposed/+archive/ubuntu/ppa/+packages that revert the fix for
CVE-2015-5180. If someone could test that the udeb's from there don't
break your pxe install that would be great.

Quite likely what will happen is if the libc6-udeb is manually installed
after it breaks and the install is continued on successfully, another
failure will happen when the libnss-dns-udeb is pulled from the ubuntu
archive, and will likely need to also be manually installed.

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[Eric Horne]

The IP workaround doesn't work because archive.ubuntu.com is a virutal
host (ie it needs the Host: header in the HTTP request). What I did to
work around that was add this to my preseed.cfg. Adjust as needed

d-i preseed/early_command string echo "91.189.88.161 archive.ubuntu.com"
>> /etc/hosts && echo "hosts: files dns" >> /etc/nsswitch.conf

I added the dns in there just in case it happened to start working again
:)

Of course, add other IPs/names that you need. If you need a lot, not
sure. I was playing with the idea of trying to get it to install 6.9
only, but I couldn't figure out how to tell it to do that (and the
early_command is too soon, and the late_command is too late).

It'd be great if 6.10 could be rolled back for now.

[Rally]

I just tested the workaround of setting the apt mirror to be an IP
instead of a hostname and it does finish the base install but our
provisioning process is still broken. We have a late_command that gets a
script to do integrations into our environment (AD domain joining,
configuration management, certificates, etc.). All of that breaks as
well because there's numerous parts that need hostname resolution.

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[Rally]

Just hit this bug with our PXE provisioning system when trying to deploy
14.04. We were deploying without issues days ago.

The syslog from the failed install shows wget to our apt mirror location
working fine until after anna retrieves
libc6-udeb_2.19-0ubuntu6.10_amd64.deb. The subsequent retrieval of
libcryptsetu4-udeb 2:1.6.1-1ubuntu1 fails due to wget being unable to
resolve host address.

It looks like libc6-udeb_2.19-0ubuntu6.10_amd64.deb in the last 24 hours
with numerous security fixes related to hostname resolution.

Thanks to Eric for suggesting the workaround.

It works if there's no virtual hosting on the mirror. As I manage a
local mirror, I changed my apache configuration and I can install with
my PXE.

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[Eric Horne]

I believe changing the preseed.cfg file to use an IP address for the
archive instead of the domain name will work around this; it's not a
good long term solution since it messes up ubuntu's dns load balancing,
but if you need to perform an install this might work. I'm in the
process of verifying this.

d-i mirror/http/hostname string archive.ubuntu.com

to

d-i mirror/http/hostname string (looked up ip address)

and... thank you all for quickly investigating the issue! :)

[Stuart Harland]

This issue does not appear to exist in the installer for xenial but
definitely effects the anna-install process for trusty.

The effect is to make the system unable to be installed.

Please see http://termbin.com/1npy which has the output of syslog from
the installer.

[Éric Paul]

Hi,

I have the same problem. I'm unable to install any 14.04 from my PXE
server. The installation proceed as expected until:

DEBUG: retrieving libc6-udeb 2.19-0ubuntu6.10

The next package triggers a:

wget: unable to resolve host address 'fr.archive.ubuntu.com'

Something strange noticed while debugging, using 'route' I get the right
resolved address for my gateway while any 'ping fr.archive.ubuntu.com'
in BBox print a:

ping: bad address 'fr.archive.ubuntu.com'

It's critical as I can't install anything.

Eric.

[Touch-packages] [Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[thedarkwinter]

Hi

To extend the info on this one:

unattended-upgrades updated this package today, and caused the same
issue for me, causing servers to stop resolving DNS internally.
Rebooting after installing resolved the issue, suggesting the update
itself is fine, but the process of updating breaks resolution.

After updating a server (without reboot), the internal DNS servers
received odd queries of type TYPE20736 (no idea what that is)

21-Mar-2017 10:38:49.627 queries: info: client 172.16.x.x#49803
(host.internal.domain): query: host.internal.domain IN TYPE20736 +
(172.16.x.x)

After rebooting said server, it starts querying normal type A records
again.

I also run some authoritative DNS servers, and have seen the same query
type from the public - suggesting that other servers out in the wild are
experiencing the same issue!

21-Mar-2017 14:22:22.578 queries: client x.x.x.x#43836 (www.domain.com):
query: www.domain.com IN TYPE20736 - (x.x.x.x)

I realize this is not directly related to the subject of this bug, but I
think its relevant.

Cheers,
Michael

[Pieter Lexis]

This problem stems from the inclusion of the fix for CVE-2015-5180. The
internal number for A +  changed in glibc (from T_UNSPEC=62321 to
T_QUERY_A_AND_=439963904).

In TCPDump, we see queries going out for TYPE62321 (the former internal
number for A+).

I think busybox uses the old symbols here?

"Suddenly" refers to the log in which it is happily downloading stuff
from the archive and after successfully downloading and installing the
libc6_2.19-0ubuntu6.10 package it is unable to download the next package
because it can no longer resolve the archive.ubuntu.com name that it had
been resolving prior to the installation of that libc6 library. I
unfortunately don't know how to get logs off the system to send in :(
