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- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
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.

What the test_bpf testcase does is only loading the test_bpf module, which reports the following error: May 20 16:57:21 autopkgtest kernel: [ 88.143826] test_bpf: #250 BPF_MAXINSNS: ld_abs+vlan_push/pop jited:1 ret -12 != 3055 FAIL (1 times) This is cased by upstream commit 636c2628086e "net: skbuff: Remove errornous length validation in skb_vlan_pop()" which we applied from stable upstream v4.4.223. [Fix] The fix is upstream commit 0d906b1e8d40 "bpf, test: fix ld_abs + vlan push/pop stress test" from v4.9 which can cherry-picked to xenial. [Test case] Load the test_bpf module, it should return no errors. [Regression potential] Low. The fix changes only a bpf test module and was tested to fix the reported issue.
