You should be able to build all the tests inside a subtest directory in tools/testing/selftests from a kernel tree with command:
make TARGETS=net
But with our 4.15 kernel these binary files in the net directory cannot be built correctly:
* reuseport_bpf
* reuseport_bpf_cpu
* reuseport_dualstack
* reuseaddr_conflict
* reuseport_bpf_numa
You can only build them with:
make TARGETS=net run_tests
This will also trigger the test, which is not ideal for the granularity improvement. |
[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 tests in net directory won't be built:
* reuseport_bpf
* reuseport_bpf_cpu
* reuseport_dualstack
* reuseaddr_conflict
* reuseport_bpf_numa
They can be build with:
make TARGETS=net run_tests
However, this will also start all of the tests in this subset, which is not ideal for the granularity improvement.
[Fix]
* 14f1889f selftests: Fix loss of test output in run_kselftests.sh
* 44f01352 selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP headers
* 8ce72dc3 selftests: fix headers_install circular dependency
These patches can be cherry-picked for Bionic. The third patch
[Test]
Tested on a baremetal node "glameow" with 4.15.0-159-generic
[Where problems could occur] |

The third patch (8ce72dc3) is the fix for this issue. To get it
applied more easily we will need the first two.

KBUILD_OUTPUT and the vm test, I think the risk of adding these two is
pretty low.
