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.

[Bug 1746474] Re: unregister_netdevice: waiting for eth0 to become free. Usage count = 5
** 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 [] msleep+0x2e/0x40 [] netdev_run_todo+0x11f/0x310 [] rtnetlink_rcv+0x2d/0x30 [] netlink_unicast+0x18c/0x240 [] netlink_sendmsg+0x2dd/0x3c0 [] sock_sendmsg+0x38/0x50 [] ___sys_sendmsg+0x2e3/0x2f0 [] __sys_sendmsg+0x54/0x90 [] SyS_sendmsg+0x12/0x20 [] do_syscall_64+0x5b/0xc0 [] entry_SYSCALL64_slow_path+0x8/0x8 [] 0x Issue submitted to LXD as well ([1]), though as indicated there, it seems to be a kernel bug.

the problem also doesn't occur on the Artful test kernel.

I also built an Artful test kernel with a back port of commit 510c321, which required commit 9620fef27ed2 as a prereq.

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.
