Networking does not work in fresh Bionic container #4510

Closed Kramerican closed 6 years ago

Kramerican commented 6 years ago

Tried with LXD v2.21 on Ubuntu 16.04 and LXD v3.0.0 on 18.04 (system upgraded from 16.04)

Networking does not come up and container does not get an Ip assigned on my network bridge.

On both my 16.04 and 18.04 host system, a xenial image comes up just fine.

I have tried provisioning from ubuntu:bionicas well as images:ubuntu/bionic/amd64 with identical results.

/var/log/syslog on the host shows in all cases lines similar to

Apr 29 20:25:15 krellide kernel: [6056886.886248] audit: type=1400 audit(1525026315.592:23530): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxd-bionic-template-xlemp72_</var/lib/lxd>" name="/sys/fs/cgroup/unified/" pid=19042 comm="systemd" fstype="cgroup2" srcname="cgroup" flags="rw, nosuid, nodev, noexec"

These lines are not present in syslog when provisioning other versions of Ubuntu (Xenial/Zesty). Interestingly upgrading an existing Xenial container to Bionic does not cause any networking issues.

Without knowing much about apparmor, I am assuming that the DENIED ... networkd line is an indicator of the culprit here. Any assistance would be much appreciated :)

Anything special about your bionic container?

Can you post lxc config show --expanded NAME?

Ok, that looks reasonable.

Also, what kernel are you running? You mentioned 18.04, so that's LXD 3.0.0 from the archive running on Ubuntu 18.04 with the 4.15 kernel correct?

Kramerican commented 6 years ago

@stgraber Yes that is correct, although the command outputs here are from my test container on my 16.04 system. I just provisioned a container with lxc init ubuntu:bionic on my 18.04 system and ran the same commands:

for completeness, on my 16.04 system inside the container uname -r shows 4.13.0-32-generic

And on 18.04 4.15.0-20-generic

stgraber commented 6 years ago

What storage backend are you using?

Kramerican commented 6 years ago

@stgraber ZFS :)

Interesting questions you are asking! I would have thought we'd be looking more specifically at the network interface. I'd love to know what theories / causes you are thinking might be at work here ...

stgraber commented 6 years ago

No luck reproducing it here on a bunch of systems. Our automated testing also shows that this image has come up with working network for weeks now...

stgraber commented 6 years ago

In your container, can you try running systemctl start systemd-networkd see if that causes the same error to show up in dmesg?

Kramerican commented 6 years ago

Oww man - this is basically a worst case scenario then. There's something in my setup messing with networking in a Bionic container specifically, but not Zesty or Xenial. On the surface this is rather bizarre. I really hate wasting your time, so I really hope this isn't down to some retarded config I have done on my end.

In any case, I am not sure if I follow your instructions correctly here, but I execute systemctl start systemd-networkd and it completes with no message (success I assume). Running dmesg in the container gives me a dmesg: read kernel buffer failed: Operation not permitted which is expected AFAIK, and running dmesg on the host reveals nothing new (no new messages) - and cat /var/log/syslog on host doesn't reveal anything new (no new messages).

If we assume I have something "unrelated" to LXD in my setup here which is messing things up, any suggestions on steps I could take to narrow things down?

stgraber commented 6 years ago

That line:

Apr 29 20:25:16 krellide kernel: [6056887.323323] audit: type=1400 audit(1525026316.029:23532): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxd-bionic-template-xlemp72_</var/lib/lxd>" name="/run/systemd/unit-root/var/lib/lxcfs/" pid=19482 comm="(networkd)" flags="ro, nosuid, nodev, remount, bind"

Is clearly what's causing the network problem, most likely it's preventing systemd-networkd from starting dhclient or something, causing the network problem you're seeing...

Can you try:

lxc launch ubuntu:18.04 test lxc exec test bash

That may help figure out what's going on.

Kramerican commented 6 years ago

Sure thing :)

Seems to me, comparing journalctl output from a working Xenial container that your hunch is right in that DHCP isn't coming up

davidfavor commented 6 years ago

Tried...

sudo ln -s /etc/apparmor.d/usr.sbin.tcpdump /etc/apparmor.d/disable/
# Then container restart. No effect.
davidfavor commented 6 years ago

Any suggestions of a fix appreciated.

Complex/Manual steps are fine.

Thanks.

davidfavor commented 6 years ago

The problem appears to be in cloud-init.

The /etc/netplan/50-cloud-init.yaml runs + silently fails.

Cloud Init log output shows all public address assigned + the DHCP address fails to be assigned + there's no error.

Refer to Upstream Ubuntu Bug: /etc/netplan/50-cloud-init.yaml fails silently with no dhcp address assigned I opened this morning.

davidfavor commented 6 years ago

The info you've posted above is non-netplan type networking.

I'm using pure Netplan at machine level + inside containers, so my setup will be very different than yours.

Kramerican commented 6 years ago

@davidfavor Fair enough - I was grasping at straws :) I have delete my comment as not to crud up this thread too much. Seems like you may have found the cause - good work David!

stgraber commented 6 years ago

@Kramerican oh, so in your case you had some custom network config for your containers? It wasn't a straight lxc launch ubuntu:bionic blah without any additional modification?

stgraber commented 6 years ago

@davidfavor do you see something in your dmesg, like the DENIAL listed above here?

And to be clear, the problem is also specifically with Ubuntu 18.04 containers running on either a 18.04 or 16.04 host, non-18.04 containers work fine for you right?

Kramerican commented 6 years ago

@stgraber Yes and no. Just doing straing lxc launch ubuntu:bionic blahwithout any additional modification also resulted in the apparmor error message and dhcp not coming up. So I don't think it's my network config per se at fault here

stgraber commented 6 years ago

Ok, I don't suppose you've got that happening on a system that you could give me access to? That'd be way too easy to debug :)

Kramerican commented 6 years ago

@stgraber Of course! I'll send you a mail with details post-haste :)

davidfavor commented 6 years ago

@stgraber, Apologies. I should have been more clear about machine/container OS.

The container OS versions are yakkety, zesty, artful.

These containers run on machines running yakkety, zesty, artful, bionic.

As soon as any machine upgrades to bionic, all containers fail.

When Netplan processes /etc/netplan/50-cloud-init.yaml there are no errors or warnings. The DHCP address simply isn't defined. The cloud-init log files provide no hint of possible problem (see data in Ubuntu cloud-init ticket referenced above).

Bionic (18.04) container work find running on machines where yakkety, zesty, artful are installed.

It's only the machine update to bionic which causes all containers to fail.

davidfavor commented 6 years ago 
dmesg | grep -i denial

Both machine level + container level produce no output.

This relates to all old containers + also the new test container I just launched which has zero modifications.

davidfavor commented 6 years ago

@stgraber, I can provide you full access to the machine having problem.

Skype me at ID davidfavor to talk about access.

davidfavor commented 6 years ago

Geez. Bionic packaging is all screwed up.

1) dnsmasq-base isn't installed at machine level.

FIX: apt-get install dnsmasq-base

2) named is running ahead of LXD setup which hijacks all interfaces, so named somehow listens on 10.X.X.X before dnsmasq, producing /var/log/syslog messages of...

dnsmasq[1846]: failed to create listening socket for 10.245.137.1: Address already in use

FIX: apt-get purge bind9

3) After reboot some progress is made.

LXD never starts + at least an error message is produced which might be useful.

Get http://unix.socket/1.0: dial unix /var/snap/lxd/common/lxd/unix.socket: connect: no such file or directory" t=2018-05-01T13:11:38+0000

So lxdbr0 never becomes available + dnsmasq can't run to route over 10.X.X.X address.

Let me know what to debug next.

Machine history. This machine had an Artful install running. Fresh install. No update from any previous OS.

LXD was installed via SNAP, so no migration of containers was done.

Containers used "lxc copy" from other machines, to arrive at this machine.

Hum...

net10 # service lxd restart
Failed to restart lxd.service: Unit lxd.service not found.
net10 # apt-file search lxd.service

So... next question is... if there's no /lib/systemd/system/lxd.service installed via snap install of LXD, how can lxd be restarted from command line.

snap start lxd

Produces loop of Failed connecting to LXD daemon (attempt 690): Get http://unix.socket/1.0: dial unix /var/snap/lxd/common/lxd/unix.socket: connect: no such file or directory till 660 timeout of waitready.

stgraber commented 6 years ago

@davidfavor sounds like you're mixing the LXD deb and snap here. When you're using the snap, you don't need dnsmasq-base installed on the host as it's included inside the snap.

The systemd unit for the snap is snap.lxd.daemon, you shouldn't have a lxd.service or lxd.socket unit around.

I suspect the problem in your case was very much bind9 conflicting with the LXD dnsmasq. To fix that, removing bind9 and then bouncing LXD with systemctl reload snap.lxd.daemon should take care of it.

You should have had a dnsmasq error in the LXD log at /var/snap/lxd/common/lxd/logs/lxd.log indicating some kind of port/address conflict. After getting rid of the conflicting and bouncing LXD, things should work again.

davidfavor commented 6 years ago

No APT + SNAP mixing on this machine.

net10 # dpkg -l | grep lxd
net10 # dpkg -l | grep lxc

There is no bind9/named conflict anymore as I've removed the packages + rebooted.

systemctl reload snap.lxd.daemon
Job for snap.lxd.daemon.service failed because the control process exited with error code.
See "systemctl status snap.lxd.daemon.service" and "journalctl -xe" for details.

Because lxd.daemon trapped in "waitready 600" after boot.

So let me know if I should just kill the "lxd waitready --timeout=600" process + try the restart.

Had to kill the "lxd waitready --timeout=600" process, because the code seems broken.

I'm guessing the code's broken as /var/log/syslog shows...

Connecting to LXD daemon (attempt 1030)

Which far exceeds --timeout=600 passed to lxd waitready.

stgraber commented 6 years ago

Yeah, kill that lxd waitready and then try the reload again, if that still fails, show the output of:

davidfavor commented 6 years ago

Issuing - systemctl reload snap.lxd.daemon - after killing off - lxd waitready --timeout=600 - just starts another - lxd waitready --timeout=600 - process, so this fails also.

stgraber commented 6 years ago

already running hmm, can you paste a full ps fauxww? I wonder if there are some leftovers somewhere in there.

davidfavor commented 6 years ago

Rebooting now. To provide clean info, as killing of lxd waitready created many partially running containers + made the ps 1000s of lines long.

davidfavor commented 6 years ago

After reboot, with lxd waitready hung...

Bottom line of problem seems to be /var/snap/lxd/common/lxd/unix.socket never gets created.

Let me know how to debug the process which creates the socket + maybe that will net some better information.

davidfavor commented 6 years ago

lxd --debug finally came back. Took 2+ minutes to create socket.

stgraber commented 6 years ago

And you still have that first shell running right, you didn't ctrl+c that shell you're running "lxd --debug --group lxd" from?

Looks like your database took two minutes to come online which is a bit unusual, @freeekanayaka is already looking into a similar issue.

davidfavor commented 6 years ago

Yes I left the original - lxd --debug --group lxd - command running, which is when I saw the 2min lag.

If I run the above command again, then I get the same hang at Initializing global database again.
