[Kernel-packages] [Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
FYI I'm still seeing this on Ubuntu 18.04 running on AWS:
# uname -a
Linux uni09.sys.timedoctor.com 4.15.0-1016-aws #16-Ubuntu SMP Wed Jul 18
09:20:54 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
When running:
lxc delete uni09-2018-08-02-08-01-46 --force
It very often ends up in ERROR state, with "unregister_netdevice:
waiting for eth0 to become free. Usage count = 1" being added to dmesg.

Bug description:
== SRU Justification ==
Commit 52df157f17e5 introduced a regression in v4.13-rc1. This regression
causes a stack trace to occur when tearing down an LXD container. The process
hangs with the following message:
"unregister_netdevice: waiting for eth0 to become free. Usage count =
5"
This regression is fixed by commit 510c321b5571, which is in mainline as of
v4.16-rc7. The fix is needed in Artful and Bionic. However, Artful needs
a prereq commit, so it's SRU request will be sent separately.
== Fix ==
510c321b5571 ("xfrm: reuse uncached_list to track xdsts")
== Regression Potential ==
Low. This commit is to fix a current regression.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
This occurs when tearing down an LXD container.

seems to be a kernel bug.

== SRU Justification ==
Commit 52df157f17e5 introduced a regression in v4.13-rc1. This regression
causes a stack trace to occur when tearing down an LXD container. The process
hangs with the following message:
"unregister_netdevice: waiting for eth0 to become free. Usage count =
5"
This regression is fixed by commit 510c321b5571, which is in mainline as of
v4.16-rc7. The fix is needed in Artful and Bionic. However, Artful needs
a prereq commit, so it's SRU request will be sent separately.

[Kernel-packages] [Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag 'verification-needed-artful' to 'verification-failed-
artful'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
I built a v3 Artful test kernel with an update to the patch requested in
the SRU feedback.
The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1746474/artful
Can you also test this kernel and see if it resolves this bug?

Bug description:
== SRU Justification ==
Commit 52df157f17e5 introduced a regression in v4.13-rc1. This regression
causes a stack trace to occur when tearing down an LXD container. The process
hangs with the following message:
"unregister_netdevice: waiting for eth0 to become free. Usage count =
5"
This regression is fixed by commit 510c321b5571, which is in mainline as of
v4.16-rc7. The fix is needed in Artful and Bionic. However, Artful needs
a prereq commit, so it's SRU request will be sent separately.
== Fix ==

Low. This commit is to fix a current regression.

A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

[Kernel-packages] [Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
I built a Bionic test kernel with commit 510c321. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1746474/bionic Can you test this kernel and see if it resolves this bug? Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages. Artful requires some back porting of that commit, so I'll perform the back port and post that kernel shortly.
