selftests/bpf: Correct the INDEX address in vmtest.sh

2021-12-20T19:01:31Z

Migration of vmtest to libbpf/ci will change the address of INDEX in vmtest.sh, which will cause vmtest.sh to not work due to the failure of rootfs fetching.

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.

selfetests/bpf: Update vmtest.sh defaults

2021-10-27T18:58:44Z

Increase memory to 4G, 8 SMP core with host cpu passthrough. This make it run faster in parallel mode and more likely to succeed. Signed-off-by: Yucong Sun Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20211025223345.2136168-2-fallentree@fb.com

selftests/bpf: Add an option for a debug shell in vmtest.sh

2021-03-31T05:05:23Z

The newly introduced -s command line option starts an interactive shell. If a command is specified, the shell is started after the command finishes executing. It's useful to have a shell especially when debugging failing tests or developing new tests. Since the user may terminate the VM forcefully, an extra "sync" is added after the execution of the command to persist any logs from the command into the log file.

selftests/bpf: Propagate error code of the command to vmtest.sh

2021-02-26T21:12:52Z

When vmtest.sh ran a command in a VM, it did not record or propagate the error code of the command. This made the script less "script-able". The script now saves the error code of the said command in a file in the VM, copies the file back to the host and (when available) uses this error code instead of its own.

bpf: Helper script for running BPF presubmit tests

2021-02-05T00:03:16Z

The script runs the BPF selftests locally on the same kernel image as they would run post submit in the BPF continuous integration framework. The goal of the script is to allow contributors to run selftests locally in the same environment to check if their changes would end up breaking the BPF CI and reduce the back-and-forth between the maintainers and the developers.
