Network namespaces didn't go in until 2.6.35-rc, how is this working on
.34.1?

Can you verify this works properly in .35-rc4?

Huh? Network namespaces were there for quite some time - just for fun I
grabbed a random older kernel (got 2.6.27.48) to check. CONFIG NET_NS
was also in there (but was defined in net/Kconfig and had a depency
on !SYSFS).

In 2.6.34 it is defined in init/Kconfig (and has no depency on SYSFS at
all).

I think I started actually using that somewhere between .30 and .32.

> Can you verify this works properly in .35-rc4?

Indeed, it works there.

There are several differencies between 2.6.34.1 and 2.6.35-rc4 in
fs/sysfs/* stuff as well as in e.g. net/core/net_namespaces.c.

I'll bisect that (but not on this atom netbook I used so far ;-) ).

Ah, yeah, but everyone used SYSFS so it probably was never used :)

I'd not recommend using it until .35-rc because of the sysfs changes
required.

...and knowing now, that basic sysfs support for netns was missing all
the time it works surprisingly well most time.

One point might be, that I never used interfaces with same name in
different network namespaces.

git bisect seems to have a somewhat pessimistic nature - it only wants
to help find out when something got broken, not when something got
fixed (good rev cannot be greater then bad rev).

So I had to do some manual mumbo jumbo to find out that
a1b3f594dc5faab91d3a218c7019e9b5edd9fe1a seems to be the one finally
fixing it, but of course depending on a zillion other ones, most
notably the ones adding sysfs support for namespaces at all...

I think I'll manage to understand that they will not fit in a stabile
patch ;-)

A I said, I'm using it quite a while now and it works surprisingly
(when knowing what is missing) well in scenarios I used so far.

Thank you very much for your support.

NET_NS: unregister_netdevice: waiting for lo to become free (after using openvpn) (was Re: sysfs bug when using tun with network namespaces)

[bug solved in 2.6.35-rcX - I used 2.6.34.1]

Now that we have solved that last one I've another glitch (this time using 2.6.35-rc4):

In an network namespace I can use an tun/tap tunnel through ssh and
when closing that namespace then eveything is fine.

But when using openvpn (also tunnel trough tun/tap) in an network
namespace and then closing that namespace I get:

Now the veth device pair used automagically vanishes and nothing

Yes, you are correct.  Care to resend all of this to the
network-namespace developer(s) and the netdev mailing list so that the
correct people are notified so they can fix it all?

Does this repeat indefinitely, or are there only a couple of repetitions?
If this repeats indefinitely every 5 seconds or so we have a serious bug.

Otherwise we just have cleanup taking longer than it should, which isn't
ideal but it is much less severe.

Just in case I provide the complete scenario again below.

If I can help somehow (provide further information, test something...)
of course I'll happily do so.

In an network namespace I can use an tun/tap tunnel through ssh and
when closing that namespace then eveything is fine.

But when using openvpn (also tunnel trough tun/tap) in an network
namespace and then closing that namespace I get:

unregister_netdevice: waiting for lo to become free
[repeated]

Please see the following two examples showing that difference:

Now the veth device pair used automagically vanishes and nothing
from that different network namespace remains - very well.

but

# > ps ax|grep openvpn|grep -v grep

# > exit # logging out from shell in network namespace

Now I get

Jul 10 20:02:36 doris kernel: unregister_netdevice: waiting for lo to
become free. Usage count = 3 [repeated]

Now one might say it is fault of openvpn (used OpenVPN 2.1_rc20
i586-suse-linux - the one in openSuSE 11.2 package - EDIT: meanwhile it
is 2.1.1, openSuSE 11.3 ), openvpn didn't close some ressource and ssh
does fine.

But: should'nt kernel clean up after process when it exits?
And/or: Should'nt kernel clean up if last process in network namespace
exits - there is nothing left which might use that interface?!

We do, and the only place you will see:
 unregister_netdevice: waiting for lo to become free. Usage count = 3 [repeated]
is when the a network namespace is being cleaned up.

However it looks like something is either taking a long time to get
cleaned up, or there is a bug and something is failing to get cleaned
up altogether thus resulting in an infinite stream of messages about waiting
for lo to become free.

I know of cases where a recent kernel can be slow to cleanup everything
attached to lo.  I don't know of any cases where it will actually fail
to clean up lo.  So I suspect all you are seeing is clean up process that
is slow and annoying not wrong.

Unfortunately looks like indefinitely. Never watched longer so far
(rebooted soon), but I'm seeing this message now repeated every 10 secs
for ~10 minutes on a idle system.

Additionally when testing this I found another one (by accident started
my firewall script in that namespace...) - using netfilter RECENT
makes it barf. Stripped down to the essentials it looks like this:

Unfortunately looks like indefinitely. Never watched longer so far
(rebooted soon), but I'm seeing this message now repeated every 10 secs
for ~10 minutes on a idle system.

Additionally when testing this I found another one (by accident started
my firewall script in that namespace...) - using netfilter RECENT
makes it barf. Stripped down to the essentials it looks like this:

Ugh.  A real bug then.  These can be a pain to track down and fix. I
think the last one of these I tracked down took a couple of weeks.  I
will start digging in when I get back from vacation.

Alexey can you look at this BUG_ON?  It looks like there has been a regression
or you missed something when you did the netns conversion of xt_recent.

Alexey can you look at this BUG_ON?  It looks like there has been a regression

OK, fortunately (hopefully) you have not put to much time onto that so
far - because everything I told about usage of tun and difference
between ssh and openvpn is complete nonsense.

I happen to have an script in that openvpn config, which puts an ipv6
address on the vpn device.

Putting an ipv6 address on a device seems to be the trigger:

OrigNS > # ip link add type veth
OrigNS > # ip link set dev veth0 up
OrigNS > # unshare -n /bin/bash
NewNS > # echo $$
<SomePID>
OrigNS > # ip link set dev veth1 netns <SomePID> # this, of course is on a different terminal
NewNS > # ip link set dev veth1 up
NewNS > # ip -6 addr add dev veth1 fd50:dead:beef::1/64
NewNS > # exit

Yields

kernel: unregister_netdevice: waiting for veth1 to become free. Usage count = 3

Oh - its veth1 this time, not lo - add an "ip link set up dev lo" in the above scenario just after the unshare, and you get the message with lo.

One might ask, if

> # unshare -n /bin/bash
> # ip link set up dev lo
> # ip -6 addr add dev veth1 fd50:dead:beef::1/64
> # exit

also does the trick, so I tried it - and it does NOT.

In the above scenario, not setting veth0 and veth1 up also makes it not happen. Only setting veth1 up also is not enough (seems to need to be "really up" what as you shurely know with veth is only the case when both sides are up).

I hope, this makes it somewhat easier to track that down.

What puzzles me is that on a slightly patched 2.6.32 (so sysfs works)
and I am doing very similar things (openvpn tunnels, ipv6 to the
network as a whole etc), and I am not seeing the infinite
unregister_netdevice: messages you are talking about.

When a network device is removed most references to it are redirected
to the loopback device so a normal network device should not see the
worst of the problems.  That is why lo showed up.

In that context I'm a bit surprised you managed trigger a problem on veth1.

I wonder what has changed with ipv6 recently.

There was a recent fix to the IGMP snooping code we have in
the bridging layer, if parsing of an ipv6 IGMP packet failed
we'd leak the packet (and thus references to whatever device
it referenced).

But this patch is not in 2.6.35 and therefore cannot make the
difference Eric sees (belives to see) between his modified 2.6.32 and
2.6.35.

Also, this patch, if I understand that correctly, only changes bridging
and in my scenario bridge.ko (have it as module) was not even loaded,
so applying this patch should not make any difference for the bug I
see, or do I overlook something?

So, I guess, your answer was general information to Erics question what
changed with ipv6, not related to that bug we seek in particular?

Hmmm, I think there are 2 possibilities:

- You send me a patch against plain 2.6.32, so I can check my
  scenarios against that kernel

or 

-  You could try yourself, its really just that few lines against a
  fresh booted system in a clean, easy to reproduce state

(Only, if you think that would yield useful information, of course).

Difference was, when that message showed up with veth1, lo in that
namespace was down while testing. When lo was up it showed up on lo.

Hi,

unfortunately the bug described below originally reported in 2.6.35-rcX
is still there in 2.6.36.

Is there anything I might do to help fix it (besides fixing it myself,
I do not have the knowhow)?

can you post your full kernel .config?

I'm using network namespaces quite extensively - OpenVPN and IPv6
included - and i haven't hit this bug. That makes it rather likely it
depends on some option difference.

btw, while the bridging bug is unrelated, it might be the same kind of
origin - a skb not being free'd. can you leave the namespace running for
a few minutes and check whether the usage count number is higher then?

I take candidates for options to change for test... ;-)

Maybe I will try to strip it down for test towards a minimal config.

Did'nt notice so far: in 2.6.35-rcX usage count was 3 every time if I
remember correctly, in 2.6.36 usage count is 1, regardless if I exit
the namespace immediately or half an hour later.

Now I have tried a kernel config with almost everything disabled -
please find below.

If I have overlooked anything I should disable (or if you suggest I
should not disable, but enable any option) - please tell me.

I've created an ~2.5MB bootable ISO image based on buildroot/busybox
with this kernel, which also shows this bug (e.g. when run in
VirtualBox).

If anybody is interested I could send this image as mail attachment or
provide a download link.

Hi,

curiously, i'm facing a similar problem in 2.6.36.1

in my container, when i configure ipv6 adress on the interfaces, 
everything seems good on the first boot of the host. If i shutdown my 
container (lxc), then boot it, i observe the following logs:
Dec  6 17:04:12 suntory.u06.univ-nantes.prive kernel: [  368.192019]

INFO: task lxc-start:3805 blocked for more than 120 seconds.

Then i must reboot the host.
The same on kernel 2.6.34, but everything is good on a 2.6.32

Some relvant informations about the kernel:
root@suntory:~# cat /boot/config-2.6.36.1-dsiun-1d | grep -i sysfs
# CONFIG_SYSFS_DEPRECATED_V2 is not set
CONFIG_ACPI_SYSFS_POWER=y
# CONFIG_WIRELESS_EXT_SYSFS is not set
CONFIG_ISCSI_BOOT_SYSFS=m
CONFIG_RTC_INTF_SYSFS=y
CONFIG_SYSFS=y
root@suntory:~# cat /boot/config-2.6.36.1-dsiun-1d | grep -i net_ns
CONFIG_NET_NS=y

Is there anything in my configuration, i must check in order to get ipv6 
working fully in the container?

Regards.

2.6.37-rc4 is working here.  There were problems earlier in the earlier
rcs. Can you try that?

There have been a couple of different reference counting bugs between
2.6.34 and the present, and I haven't tracked them, just noticed they
exist.

Can reproduce the following still on 2.6.36.1, but NOT on 2.6.37-rc4 -
so indeed seems to be fixed!


Putting an ipv6 address on a device seems to be the trigger:

OrigNS > # ip link add type veth
OrigNS > # ip link set dev veth0 up
OrigNS > # unshare -n /bin/bash
NewNS > # echo $$
<SomePID>
OrigNS > # ip link set dev veth1 netns <SomePID> # this, of course is
on a different terminal NewNS > # ip link set dev veth1 up
NewNS > # ip -6 addr add dev veth1 fd50:dead:beef::1/64
NewNS > # exit

Yields

kernel: unregister_netdevice: waiting for veth1 to become free. Usage
count = 3

I once spent a similar amount of time putting in debug variants that
printed info for each time a netdev was acquired and released.

Maybe a similar logic could be put into the official kernel (and
disabled by default)?

That should save effort in the long run, I'd think.

Thanks,
Ben

Thanks for forwarding this report. I'll take a look and try to reproduce

Re: sysfs bug when using tun with network namespaces

Sorry, I should have send the further communication CC: to you.

This one is resolved, it is due to missing support for namespaces
almost at all in sysfs prior to 2.6.35-rc, bug does not appear
in .35-rcX anymore.

But I have found another one:

[bug  (no sysfs support for net namespaces at all) solved in 2.6.35-rcX
- I used 2.6.34.1]

Now that we have solved that last one I've another glitch (this time using 2.6.35-rc4):

In an network namespace I can use an tun/tap tunnel through ssh and
when closing that namespace then eveything is fine.

But when using openvpn (also tunnel trough tun/tap) in an network
namespace and then closing that namespace I get:

unregister_netdevice: waiting for lo to become free
[repeated]

Please see the following two examples showing that difference:

# > unshare -n /bin/bash
# > # how to setup veth device pair to get connectivity into namespace not shown here
# > tunctl -u ml -t tap1
# > ssh -o Tunnel=Ethernet -w 1:1 somewhere
[ running some traffic over tap1 not shown here ]
^d # logging out from somewhere
# > tunctl -d tap1
# > exit # logging out from shell in network namespace

Now the veth device pair used automagically vanishes and nothing
from that different network namespace remains - very well.

but

# > unshare -n /bin/bash
# > # how to setup veth device pair to get connectivity into namespace not shown here
# > openvpn --config some.config

# > ps ax|grep openvpn|grep -v grep
# > # cannot find anything that suggests there is anything left from that openvpn session
# > exit # logging out from shell in network namespace

Now I get

Jul 10 20:02:36 doris kernel: unregister_netdevice: waiting for lo to become free. Usage count = 3
[repeated]

Now one might say it is fault of openvpn (used OpenVPN 2.1_rc20
i586-suse-linux - the one in openSuSE 11.2 package), openvpn didn't
close some ressource and ssh does fine.

But: should'nt kernel clean up after process when it exits?
And/or: Should'nt kernel clean up if last process in network namespace
exits - there is nothing left which might use that interface?!

[X] done - hopefully, cannot find a particular network namespace
developer in MAINTAINERS or source files. If such a one exists, please
forward.

Thanks.
