selftests/bpf: Add sockopt case to verify prog_type

2024-04-30T17:43:37Z

Make sure only sockopt programs can be attached to the setsockopt and getsockopt hooks. Signed-off-by: Stanislav Fomichev Acked-by: Eduard Zingerman Link: https://lore.kernel.org/r/20240426231621.2716876-4-sdf@google.com Signed-off-by: Martin KaFai Lau

selftests/bpf: Extend sockopt tests to use BPF_LINK_CREATE

2024-04-30T17:43:37Z

Run all existing test cases with the attachment created via BPF_LINK_CREATE. Next commit will add extra test cases to verify link_create attach_type enforcement.

selftests/bpf/sockopt: Add io_uring support

2023-10-19T22:42:04Z

Expand the sockopt test to use also check for io_uring {g,s}etsockopt commands operations. This patch starts by marking each test if they support io_uring support or not. Right now, io_uring cmd getsockopt() has a limitation of only accepting level == SOL_SOCKET, otherwise it returns -EOPNOTSUPP. Since there aren't any test exercising getsockopt(level == SOL_SOCKET), this patch changes two tests to use level == SOL_SOCKET, they are "getsockopt: support smaller ctx->optlen" and "getsockopt: read ctx->optlen". There is no limitation for the setsockopt() part. Later, each test runs using regular {g,s}etsockopt systemcalls, and, if liburing is supported, execute the same test (again), but calling liburing {g,s}setsockopt commands. This patch also changes the level of two tests to use SOL_SOCKET for the following two tests. This is going to help to exercise the io_uring subsystem: * getsockopt: read ctx->optlen * getsockopt: support smaller ctx->optlen Signed-off-by: Breno Leitao Link: https://lore.kernel.org/r/20231016134750.1381153-12-leitao@debian.org Acked-by: Martin KaFai Lau Signed-off-by: Jens Axboe

selftests/bpf: Check whether to run selftest

2023-05-25T23:51:05Z

The sockopt test invokes test__start_subtest and then unconditionally asserts the success. That means that even if deny-listed, any test will still run and potentially fail. Evaluate the return value of test__start_subtest() to achieve the desired behavior, as other tests do.

selftests/bpf: Update EFAULT {g,s}etsockopt selftests

2023-05-13T23:55:44Z

Instead of assuming EFAULT, let's assume the BPF program's output is ignored. Remove "getsockopt: deny arbitrary ctx->retval" because it was actually testing optlen. We have separate set of tests for retval. Signed-off-by: Stanislav Fomichev Link: https://lore.kernel.org/r/20230511170456.1759459-3-sdf@google.com Signed-off-by: Martin KaFai Lau

selftests/bpf: Convert legacy prog load APIs to bpf_prog_load()

2021-11-07T16:34:23Z

Convert all the uses of legacy low-level BPF program loading APIs (mostly bpf_load_program_xattr(), but also some bpf_verify_program()) to bpf_prog_load() uses.
