[Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
I built one more Atrful 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 test this kernel and see if it resolves this bug? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746474 Title: unregister_netdevice: waiting for eth0 to become free.

** Description changed:
+ == 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.
LXD monitor process hangs with the following stack:
$ sudo cat /proc/27043/stack

Issue submitted to LXD as well ([1]), though as indicated there, it
seems to be a kernel bug.

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.
