Re-open this bug as this is still an issue.

The test_bpf test in net failed with GKE 5.0.0-1030.31:
  test_bpf: [FAIL]
  not ok 1..9 selftests: net: test_bpf.sh [FAIL]

Further investigate shows this module will require config_test_bpf to be
enabled in the kernel config.

** Changed in: ubuntu-kernel-tests
       Status: Invalid => Confirmed

** No longer affects: linux (Ubuntu Cosmic)

** Summary changed:

- test_bpf in net from ubuntu_kernel_selftests failed on KVM / Cosmic kernels
+ test_bpf in net from ubuntu_kernel_selftests failed on cloud kernels

** Changed in: linux-kvm (Ubuntu)
       Status: Invalid => Confirmed

** No longer affects: linux-kvm (Ubuntu Cosmic)

Bug description:
  This test will attempt to insert the test_bpf module, but this module
  does not exist in KVM kernels:

  $ sudo modprobe test_bpf
  modprobe: FATAL: Module test_bpf not found in directory /lib/modules/4.15.0-1028-kvm

  The script:
  $ sudo ./test_bpf.sh 
  test_bpf: [FAIL]

  $ cat test_bpf.sh 
  #!/bin/sh
  # SPDX-License-Identifier: GPL-2.0
  # Runs bpf test using test_bpf kernel module

  if /sbin/modprobe -q test_bpf ; then
  	/sbin/modprobe -q -r test_bpf;
  	echo "test_bpf: ok";
  else
  	echo "test_bpf: [FAIL]";
  	exit 1;
  fi

  This test_bpf module will need the CONFIG_TEST_BPF to be enabled.
