Title:
test_bpf of ubuntu_kernel_selftests.net ADT test failure with linux
4.4.0-180.210
Status in ubuntu-kernel-tests:
Fix Released
Status in linux package in Ubuntu:

Bug description:
[Impact]
Testcase test_bpf of ubuntu_kernel_selftests.net regressed on xenial/linux
4.4.0-180.210.
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.
