selftests/bpf: Consolidate VIRTIO/9P configs in config.vm file

2023-11-10T03:07:38Z

Those configs are needed to be able to run VM somewhat consistently. For instance, ATM, s390x is missing the `CONFIG_VIRTIO_CONSOLE` which prevents s390x kernels built in CI to leverage qemu-guest-agent. By moving them to `config,vm`, we should have selftest kernels which are equal in term of VM functionalities when they include this file. The set of config unabled were picked using grep -h -E '(_9P|_VIRTIO)' config.x86_64 config | sort | uniq added to `config.vm` and then grep -vE '(_9P|_VIRTIO)' config.{x86_64,aarch64,s390x} as a side-effect, some config may have disappeared to the aarch64 and s390x kernels, but they should not be needed. CI will tell. Signed-off-by: Manu Bretelle Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20231031212717.4037892-1-chantr4@gmail.com Signed-off-by: Alexei Starovoitov

selftests/bpf: Fix vmtest.sh getopts optstring

2022-08-09T20:30:02Z

Before, you could see the following errors: $ ./vmtest.sh -j ./vmtest.sh: option requires an argument -- j ./vmtest.sh: line 357: OPTARG: unbound variable $ ./vmtest.sh -z ./vmtest.sh: illegal option -- z ./vmtest.sh: line 357: OPTARG: unbound variable Fix by adding ':' as first character of optstring. Reason is that getopts requires ':' as the first character for OPTARG to be set in the `?` and `:` error cases. Note that the ':' as the first character of the optstring switches getopts to silent mode. The desire to run in this mode seems to have been there all along, as the script takes care of reporting errors.

selftests/bpf: Fix vmtest.sh -h to not require root

2022-08-09T20:28:48Z

Set the exit trap only after argument parsing is done. This way argument parse failure or `-h` will not require sudo. Reasoning is that it's confusing that a help message would require root access.

selftests/bpf: Adjust vmtest.sh to use local kernel configuration

2022-07-27T15:03:14Z

So far the vmtest.sh script, which can be used as a convenient way to run bpf selftests, has obtained the kernel config safe to use for testing from the libbpf/libbpf GitHub repository [0]. Given that we now have included this configuration into this very repository, we can just consume it from here as well, eliminating the necessity of remote accesses. With this change we adjust the logic in the script to use the configuration from below tools/testing/selftests/bpf/configs/ instead of pulling it over the network.

selfetests/bpf: Adapt vmtest.sh to s390 libbpf CI changes

2021-11-18T17:57:04Z

[1] added s390 support to libbpf CI and added an ${ARCH} prefix to a number of paths and identifiers in libbpf GitHub repo, which vmtest.sh relies upon. Update these and make use of the new s390 support.
