Bug description:
[SRU Justification]
== Impact ==
Some upstream stable change modified the bpf selftest to use a function that
probes for existing eBPF program types. However that function does not exist in
the 5.0 kernel sources.
== Fix ==
Picking two additional changes from upstream (which only modify the tools
sub-directory), allows to compile the selftests again.
== Risk of Regression ==
Since the kernel itself is not touched, the risk is low.
== Testcase ==
With build-essential installed and the Disco kernel tree cloned:
cd tools/testing/selftests/
TARGET=net make
---
This test will failed to build on 5.0.0-16 Disco.
5.0.0-16 Disco + 5.0.0-15 source code - build OK
5.0.0-16 Disco + 5.0.0-16 source code - Failed
Bisect shows this one e38969c9 (selftests/bpf: skip verifier tests for
unsupported program types) in our tree is the cause (upstream commit:
8184d44c)
Which uses a "recently introduced bpf_probe_prog_type()" to skip test.
And we don't have it implemented.
