BPF selftests mandate certain kernel configuration options to be present in order to pass. Currently the "reference" config files containing these options are hosted in a separate repository [0]. From there they are picked up by the BPF continuous integration system as well as the in-tree vmtest.sh helper script, which allows for running tests in a VM-based setup locally. But it gets worse, as "BPF CI" is really two CI systems: one for libbpf (mentioned above) and one for the bpf-next kernel repository (or more precisely: family of repositories, as bpf-rc is using the system). As such, we have an additional -- and slightly divergent -- copy of these configurations. This patch set proposes the merging of said configurations into this repository. Doing so provides several benefits: 1) the vmtest.sh script is now self-contained, no longer requiring to pull configurations over the network 2) we can have a single copy of these configurations, eliminating the maintenance burden of keeping two versions in-sync 3) the kernel tree is the place where most development happens, so it is the most natural to adjust configurations as changes are proposed there, as opposed to out-of-tree, where they would always remain an afterthought The patch set is structed in such a way that we first integrate the first set of configurations [0], then we add the difference to the second one [1], and lastly we adjust the vmtest.sh script to pick up the local configuration instead of reaching out to GitHub.
