[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection "eth0" that does not work

2018-02-23 Thread Matthijs Kooijman
Hey folks,

previously, people suggested completely disabling ipv6 as a workaround
(or at least debugging tool). This, combined with the previous analysis
made me realize another workaround: Just disable ipv6 autoconf by the
kernel. I dropped these two lines in my sysctl.conf:

net.ipv6.conf.eth0.autoconf=0
net.ipv6.conf.eth0.accept_ra=0

Now, this bug seems to be gone (even with the 5-second sleep, tried
twice so far). From my logs, I see that a link-local ipv6 address is
still assigned, but apparently that does not trigger the broken
behaviour.

Also, this only prevents ipv6 configuration during the initial boot,
when the boot is complete, eth0 has a complete set of ipv6 addresses as
well (presumably because NetworkManager handles this).

Gr.

Matthijs

[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection "eth0" that does not work

2018-02-23 Thread Matthijs Kooijman
Package: network-manager
Version: 1.10.4-1+b1
Followup-For: Bug #755202

Hi folks,

I've also been seeing this bug on my system for quite some while now,
and decided to investigate today. I haven't quite figured it out, but
I'll share my findings here.

>From the previous discussion on this bug, most notably the IRC log
posted, I understand that the problem is somewhat like this:
 - On boot, something brings up the ethernet interface (or are network
   interfaces up by default?)
 - The interface gets a link-local ipv6 and/or statelessly
   autoconfigured global ipv6 address (handled by the kernel, I
   believe?).
 - NetworkManager starts, and finds a (partially configured interface).
 - NetworkManager starts managing the interface (with reason
   'connection-assumed') and creates a new (temporary) connection
   profile called 'eth0' that copies the current settings from the
   interface.
 - NetworkManager does *not* activate the normal default connection
   profile for the interface.

I haven't been able to confirm the above is exactly what happens, but my
observations do seem to match the above theory.



I have been trying to pinpoint the code path that handles it, without
much succes. I enabled trace logging (see NetworkManager.conf below) and
that caused debug and trace log entries to appear, but nothing I could
completely correlate with the source.

Here's the relevant bit of the log, where it apparently decides to
create a new connection. This is from 1.6.2, but with the output is
pretty much the same with 1.10.4.

  device (eth0): link connected
  manager: (eth0): new Ethernet device 
(/org/freedesktop/NetworkManager/Devices/2)
  manager: (eth0.10): new VLAN device 
(/org/freedesktop/NetworkManager/Devices/3)
  manager: (eth0.253): new VLAN device 
(/org/freedesktop/NetworkManager/Devices/4)
  keyfile: add connection in-memory

'connection-assumed') [10 20 41]
  device (eth0): state change: unavailable -> disconnected (reason

  device (eth0): Activation: starting connection 'eth0' 
(056caea2-6833-42cc-bdc5-bd8c5744c8a9)

Looking at the source, I would expect these lines to come from:

  keyfile: add connection in-memory 
(056caea2-6833-42cc-bdc5-bd8c5744c8a9,"eth0")

https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1846

https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1762
  device (eth0): state change: unmanaged -> unavailable (reason 
'connection-assumed') [10 20 41]

  device (eth0): state change: unavailable -> disconnected (reason

https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1860

https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1793-L1797

However, in that case I would also expect to see these messages:

  
https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1758-L1760
  
https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L1789-L1791

I've looked at other code paths that could lead to these
connection-assumed state changes, but each path I could find would also
log additional messages that I'm not seeing here.

It doesn't seem that debug messages for the device domain, or
nm-manager.c are broken, since I *do* see this message:

  manager: setup NMManager singleton (0x559e10330041)
  
https://github.com/NetworkManager/NetworkManager/blob/1.6.2/src/nm-manager.c#L5688

All this looks at 1.6.2, but I've had a similar (but not as thorough)
look at 1.10.4 which looks pretty much the same.



Another observation I made is that:
 - With 1.6.2, if I set two (out of two) VLAN connections I had to
   autostart=false, the problem would disappear.
 - With 1.10.4, if I set both VLAN connections to autostart=false, the
   problem would remain. Also if I completely removed them.
 - With 1.6.2, if I removed the VLAN connections, but added
   `ExecStartPre=/bin/sh -c "sleep 5"` to the systemd service file, the
   problem would appear again.

Given that, the link-up message from the kernel in my log is only
shortly before NM starts (within the same second), I suspect that there
is a race condition with NM looking at the interface and the kernel
configuring it, and the VLAN connections I have subtly influence the
timing.


I've also disabled avahi, which does not seem to influence the problem
at all (with avahi enabled, it generates log output about registering
addresses, but I believe it does this *in response to* the addresses
being added by the kernel, not the other way around.

[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection "eth0" that does not work

2017-05-04 Thread Daniel Reichelt
Hi folks,

here are some more insights into this mystery:

My "victim" box:

- kvm-guest: jessie, task-xfce-desktop, sysvinit instead of systemd
- running with -net nic,model=rtl8139 -net tap
- connected to br0 of the kvm host which also contains the host's eth0
- the guest's /etc/network/interfaces or NM-config were left unchanged
after jessie-netinstall


In the guest, I did:

# touch /etc/.legacy-bootordering

and tweaked /etc/init.d/rc to display `ip addr list` and a debug login
shell after the execution of every single init script. Now, after
/etc/rcS.d/S03udev got executed, udev modprobe'd 8139too/8139cp for the
virtual Realtec nic.

What *really* surprised me: The output of `ip addr list` after S03udev
finished showed different link states across different boot processes.
AFAICT the Realtek's link state after modprobing is determined by fair
dice roll. I couldn't infer any relation between the link state after
modprobing and

- a freshly invoked kvm guest
- shutdown -r from within the guest
- echo b >/proc/sysrq-trigger from within the guest
- "system_reset" sent to the qemu_system-x86_64 process's control socket

- the link state prior to any of these four variants to reboot



As a consequence I could observe:

- When the link state was DOWN after modprobing, of course no v6 SLAAC
happened and NM configured eth0 just fine with both v4 and v6.

- When the link state was UP after modprobing, SLAAC happened which
triggered NM's "undesired behavior" to "connection-assume" eth0.
(This case then easily becomes a race-condition with concurrent
execution of the init scripts.)



Judging whether this is an error in this specific driver or in the Linux
networking layer goes way over my head. At the very least I can say that
I'm completely baffled by this observation.



Cheers

Daniel

[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection eth0 that does not work

2015-04-15 Thread Fitz carraldo
Actually, since my last message (#161) I 
have found that, very, very occasionally, an invalid second eth0 
connection is created even in the following situation:



IPv6 enabled in aliases.conf: yes

IPv6 enabled in avahi-daemon.conf: no

[ipv6] method=ignore

[ipv4] method=auto

[ipv4] may-fail=false



So it seems the only sure-fire way of stopping NetworkManager from 
creating an invalid second eth0 connection (IPv6 Link-Local connection) is to 
disable IPv6 
system-wide.

2015-03-31 Thread Michael Biebl
Talked to upstream about this problem.
Attached is the IRC log.

-- 
Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
mbiebl dcbw: this bug report is a mess: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755202
mbiebl do you have any idea what this could be about?
dcbw mbiebl: what creates eth0:avahi?
dcbw mbiebl: and why does it not just add the address as a secondary...
dcbw mbiebl: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755202#136 
looks like an accurate description of the problem
dcbw mbiebl: something is assigning an address to the interface before NM 
starts up (possibly the kernel with IPv6LL) and NM respects that configuration 
on boot
dcbw mbiebl: it will name that generated+assumed connection the same as the 
interface name, so I guess everyone on the bug isn't using systemd/udev network 
renaming becuase they all talk about 'eth0'
mbiebl dcbw: the new udev persistent network interface naming is opt-in in 
Debian
mbiebl eth0:avahi is a link-local fallback created by avahi-autopid
mbiebl if e.g. dhclient times out
mbiebl dcbw: but I have no idea really what's going on there
dcbw mbiebl: the question is, why is it using address labels and not just 
adding it to the interface, but that's not your problem
dcbw mbiebl: I think that #136 is the basic issue
dcbw mbiebl: the eth0 things are in-memory connections generated from the 
existing interface state when NM starts, so that it doesn't disrupt the 
existing interface configuration
dcbw mbiebl: and it won't work, because it's link-local so you don't get 
anywhere
mbiebl apparently this is not debian specific
mbiebl but I wasn't able yet, to distill the exact reproducer
dcbw no, it's not debian specific
dcbw mbiebl: it will only occur if (a) something brings the interface up 
before NetworkManager starts, and (b) the kernel has had enough time to run DAD 
on the IPv6LL address that it adds because the interface is IFF_UP already
dcbw mbiebl: a reproducer would be something like
dcbw 1) stop NM
dcbw 2) ip addr flush all
dcbw 3) ifconfig eth0 down
dcbw 4) ifconfig eth0 up
dcbw 5) wait until the kernel has assigned an IPv6LL address
dcbw 6) start NetworkManager
dcbw and you'll see NM assume the connection on eth0 that is 
ipv4.method=disabled, ipv6.method=link-local
dcbw that's essentially intended but sub-optimal behavior, as a side-effect 
of NM attempting not to touch already configured interfacs
mbiebl so if the user has a valid connection config for eth0 this is not 
applied?
dcbw in the case of IPv6LL-only, it's less than helpful
dcbw mbiebl: existing interface configuration trumps *all*, because if the 
configuration already exists on the interface, something put it there, and NM 
tries not to interfere
dcbw mbiebl: int he case of IPv6LL, well, that is usually not intended by the 
user
dcbw so we probably do want to adjust NM behavior in the IPv6LL-only case
mbiebl same for an avahi created IPv4LL
dcbw well, that's intended because somebody installed the dhclient script or 
whatever
dcbw plus, avahi-autoipd is going do to die pretty soon, according to upstream
dcbw I have no idea why that avahi behavior is useful
mbiebl will that be folded into networkd?
dcbw there's already replacement code in networkd, and NM does IPv4LL itself 
too, and so does connman
dcbw so basically, since it's a network management daemon task and not really 
a standalone thing, I guess they decided it should be done in management daemons
mbiebl yeah, it was probably just useful for basic tools like ifupdown
mbiebl (it's hooked into it via if-up.d hooks and a dhclient hook)
dcbw mbiebl: for the IPv4LL side of things, if the user wants IPv4LL, then 
they can (a) create a config in NM for it that they can use when they want, 
and/or (b) we can explore ways to achieve whatever behavior they want within 
NM, like potential fallback to IPv4LL when DHCP fails or whatever
dcbw mbiebl: so two results from that thread; #1 NM's IPv6LL-only assume 
behavior should be changed, and #2 avahi-autoipd probably shouldn't be called 
from the hooks to add an address
dcbw at least when NM is being used...
mbiebl oh, I still have an avahi-autoipd suggests in the NM package 
mbiebl probably from old times...
mbiebl suggests don't pull in the package automatically thankfully
dcbw mbiebl: well, complicated
dcbw mbiebl: it's required currently for NM's IPv4LL behavior, but NM spawns 
it manually
dcbw mbiebl: we're going to remove that dependency soon thouh
mbiebl or, well, it actually still has code for IPv4LL using avahi
dcbw mbiebl: so you would still want avahi-autoipd, but you don't want the 
hooks running when NM is running
dcbw at least the ones that add addresses
mbiebl the if-up.d hooks (which are called by the NM dispatcher)
mbiebl only add routes
mbiebl it's the dhclient hook, which adds the avahi interface
mbiebl since we don't call the dhclient hook scripts
mbiebl this probably only happens if the user manages

Hi Felix, Zack, et al!

I'm not able to reproduce this issue with the information provided so
far or able to conclude what the issue is.. Unfortunately, this bug
report has become a bit of a hodgepodge. I'm not sure if all the me-too
reports are actually the same issue.

So, it would be immensly helpful, if someone can provide me with a
detailed description of his network setup (what interfaces are managed
by NetworkManager, what by ifupdown, what's the individual configuration
and available interfaces, etc.).
Then the exact circumstances, when this happens and if this happens
reliably and how it can be triggered.
Also, I'll need a verbose debug log from NetworkManager [1].

Ideally, someone provides steps how I can reproduce the issue myself
(e.g. by started from a basic/standard Debian Jessie installation).


Thanks,
Michael

[1] That means running NetworkManager (as root) with the following
command line arguments:
NetworkManager --no-daemon --log-level=DEBUG --debug
It's possible, that you need to remove the D-Bus activation symlinks,
i.e. run systemctl disable NetworkManager.service; systemctl stop
NetworkManager.service; debug; systemctl enable
NetworkManager.service; systemctl start NetworkManager.service

[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection eth0 that does not work

2015-03-11 Thread Joseph Rawson
Hi!

I just came across this bug after reading the latest status report:
https://lists.debian.org/debian-devel-announce/2015/03/msg2.html

I have a laptop that has been running jessie for a few months.  I use
NetworkManager to configure the wifi, but use /etc/network/interfaces for
eth0.

I experience a very similar problem when booting at a coffee shop where I
use wifi and ethernet is disconnected.  In this circumstance, eth0 fails
to get a lease (not surprising as there's no wire), but the exit hook
calls avahi-autoipd (/usr/sbin/avahi-autoipd -wD).  This is supposed to
set an ip address for eth0 until it is otherwise assigned, AFAICT.  The
problem seems to occur when setting a route, which seems to be done in
/etc/avahi/avahi-autoipd.action.  This is mentioned in this bug report: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=533233 (wishlist bug).

The metric for my wlan0 route was 1024, so I set the base metric to 1025,
instead of 1000, in the autoipd.action file, and my wifi route wasn't
precluded by avahi-autoipd.

I don't know how much help this is, since I'm not really using
NetworkManager for ethernet, and only wifi, but if NetworkManager uses
dhclient, then encounters the avahi-autoipd hooks, the result could be
similar to the situation I described.

I had the same or similar problem, except that only IPv4 was disabled. It 
seems that the cause in my case was that I tried to load netconsole on the 
kernel command line, which I think worked before I switched to systemd and/or 
stopped using ifupdown. Now when didn't try to load netconsole automatically, 
no automatic connection was created, but the interface was renamed from eth0 
to eth1. systemd still reported that mounting remote file systems failed, but 
the network connection came up and /home was mounted eventually nonetheless.

Strangely enough, checking /etc/udev/rules.d/70-persistent-net.rules (last 
modified in August), there is an eth0 line with a MAC address that doesn't 
match the current address of my NIC, and an eth1 line that does, but I'm 
pretty sure that the actual address hasn't been changing, and it matches 
/etc/NetworkManager/system-connections/eth0, which hasn't been changed since 
before the last boot.

I did also rename the connection in NetworkManager, but that should't have any 
consequences, should it?

I suppose it would have been possible to work around the problem by adding a 
no-auto-default setting to NetworkManager.conf.

I'm not sure what to make of this but it seems that loading netconsole was 
bringing the interface up early (but leaving it unconfigured), which may have 
confused NM. It may also have prevented udev from renaming it, but I don't 
know if these points are related.

[Pkg-utopia-maintainers] Bug#755202: network-manager: keeps creating and using new connection eth0 that does not work

2014-07-30 Thread Vladimir K
I can assume NM creates virtual 'eth0' profile when it sees that interface is 
already brought up and configured.
This profile does not exist as a file in /etc/NetworkManager/system-connections.

I'm using several named connection profiles with associated dispatcher scripts. 
If there is a need for NM to be restarted, usually correct profile is restored. 
But if interface configuration was somehow altered by something other than NM, 
then after restart it uses this dynamic 'eth0' profile instead of correct one. 
Annoying. I hope there is or will be a way to disable this feature, as it is 
clearly misfires sometimes.

I'm seeing this as well. Furthermore, it seems to get in the way of
other interfaces such as wifi, meaning that if you're regularly using a
wifi, every time a new eth0 interface kicks in you lose connectivity.

To give in idea, currently my laptop has 9 bogus eth0 interfaces, in
addition to the right one (i.e., ifupdown (eth0) and another static
one I've configured).

I haven't yet understood when exactly network-manager adds a new one,
but at each resume for suspend I lose connectivity, but not only. For
instance, since the last resume (~1 hour ago) I had to manually disable
a bogus eth0 interface at least 3 times.  As you can imagine, this is
really getting in the way of using my computer productively --- hence my
severity tweaking.

If you've ideas on how I can help you debug the problem, let me know.

wired connection (standard dhcp) in gnome3 (or using nmcli), but it
keeps creating the eth0 interface and using it after restarting.

* Purging and re-installing NM does not help.
* Modifying the eth0 connection to enable ipv4 or creating a new
  connection named eth0 that has ipv4 enabled does not help -- NM
  will simply create another connection named eth0 and use that.
* /var/log/syslog did not seem to include anything useful.

I really have no idea what's going on here.  I hope someone else does.
Thanks.
