Title:
Unable to build net/reuseport_bpf and other tests in
ubuntu_kernel_selftests on Bionic with make command
Status in ubuntu-kernel-tests:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
Bug description:
[Impact]
With 4.15 kernel, not all binary files inside a subtest directory in
tools/testing/selftests of a kernel tree can be built with command:
make TARGETS=$subtest
For example, the following binaries in net directory won't be built:
* reuseport_bpf
* reuseport_bpf_cpu
* reuseport_dualstack
* reuseaddr_conflict
* reuseport_bpf_numa
They can only be build with:
make TARGETS=net run_tests
However, this will also start all of the tests in this subset and it's
is not ideal for the granularity improvement, in which we will want to
run tests one-by-one.
[Fix]
1. 14f1889f selftests: Fix loss of test output in run_kselftests.sh
2. 44f01352 selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP
headers
3. 8ce72dc3 selftests: fix headers_install circular dependency
4. 27d79a2b selftests: fix bpf build/test workflow regression when
KBUILD_OUTPUT is set
5. e2e88325 selftests: vm: Fix test build failure when built by itself
The 1st and 5th patch can be cherry-picked. The 2nd needs to be
backported with some context adjustment (can be applied with git -cp
but not git am -C2). The 3rd and 4th patch would need to be applied
with -C2.
The third patch (8ce72dc3) is the fix for this issue. To get it
applied more easily we will need the first two.
The 4th (27d79a2b) and the 5th (e2e88325) patches are included here as
they have been marked as a fix for 8ce72dc3. Since we don't use
KBUILD_OUTPUT and the vm test, I think the risk of adding these two is
pretty low.
[Test]
Tested on a baremetal node "glameow" with 4.15.0-159-generic, the test
cases number and results are identical before and after applying this
change (compared side-by-side).
Please find attachment in the bug report for the test result.
[Where problems could occur]
As this is just tested with generic Bionic 4.15 kernel on a bare-metal
system, it's is possible to see other issues on different variants. If
this change is incorrect it will cause issue to our automated-testing
and regression-testing, but it won't affect the real kernel
functionality.
