2024-09-05selftests/bpf: Add riscv64 configurations to local vmtestPu Lehui
Add riscv64 configurations to local vmtest. We can now perform cross platform testing for riscv64 bpf using the following command: PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- vmtest.sh \ -l ./libbpf-vmtest-rootfs-2024.08.30-noble-riscv64.tar.zst -- \ ./test_progs -d \ \"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \ | cut -d'#' -f1 \ | sed -e 's/^[[:space:]]*//' \ -e 's/[[:space:]]*$//' \ | tr -s '\n' ','\ )\" Tested-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Pu Lehui <pulehui@huawei.com> Link: https://lore.kernel.org/r/20240905081401.1894789-10-pulehui@huaweicloud.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2024-09-05selftests/bpf: Enable cross platform testing for vmtestPu Lehui
Add support cross platform testing for vmtest. The variable $ARCH in the current script is platform semantics, not kernel semantics. Rename it to $PLATFORM so that we can easily use $ARCH in cross-compilation. And drop `set -u` unbound variable check as we will use CROSS_COMPILE env variable. For now, Using PLATFORM= and CROSS_COMPILE= options will enable cross platform testing: PLATFORM=<platform> CROSS_COMPILE=<toolchain> vmtest.sh -- ./test_progs Tested-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Pu Lehui <pulehui@huawei.com> Link: https://lore.kernel.org/r/20240905081401.1894789-7-pulehui@huaweicloud.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2024-09-05selftests/bpf: Support local rootfs image for vmtestPu Lehui
Support vmtest to use local rootfs image generated by [0] that is consistent with BPF CI. Now we can specify the local rootfs image through the `-l` parameter like as follows: vmtest.sh -l ./libbpf-vmtest-rootfs-2024.08.22-noble-amd64.tar.zst -- ./test_progs Meanwhile, some descriptions have been flushed.

2024-09-05selftests/bpf: Limit URLS parsing logic to actual scope in vmtestPu Lehui
The URLS array is only valid in the download_rootfs function and does not need to be parsed globally in advance. At the same time, the logic of loading rootfs is refactored to prepare vmtest for supporting local rootfs.

2023-11-09selftests/bpf: Consolidate VIRTIO/9P configs in config.vm fileManu Bretelle
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.

2022-08-09selftests/bpf: Fix vmtest.sh getopts optstringDaniel Xu
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.

2022-08-09selftests/bpf: Fix vmtest.sh -h to not require rootDaniel Xu
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.

2022-07-27selftests/bpf: Adjust vmtest.sh to use local kernel configurationDaniel Müller
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.

2021-03-30selftests/bpf: Add an option for a debug shell in vmtest.shKP Singh
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.

2021-02-26selftests/bpf: Propagate error code of the command to vmtest.shKP Singh
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.

2021-02-04bpf: Helper script for running BPF presubmit testsKP Singh
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.
