selftests/bpf: Fix typos and grammar in test sources

2025-08-27T22:13:08+00:00

Fix spelling typos and grammar errors in BPF selftests source code. Signed-off-by: Shubham Sharma Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20250826125746.17983-1-slopixelz@gmail.com

selftests/bpf: add tests for the "module: Function" syntax

2024-05-01T16:53:48+00:00

The previous patch added support for the "module:function" syntax for tracing programs. This adds tests for explicitly specifying the module name via the SEC macro and via the bpf_program__set_attach_target call.

selftests/bpf: Use un/load_bpf_testmod functions in tests

2023-05-17T05:09:23+00:00

Now that we have un/load_bpf_testmod helpers in testing_helpers.h, we can use it in other tests and save some lines. Acked-by: David Vernet Signed-off-by: Jiri Olsa Link: https://lore.kernel.org/r/20230515133756.1658301-7-jolsa@kernel.org Signed-off-by: Alexei Starovoitov

selftests/bpf: Add kprobe_multi check to module attach test

2022-10-25T17:14:51+00:00

Adding test that makes sure the kernel module won't be removed if there's kprobe multi link defined on top of it. Acked-by: Song Liu Signed-off-by: Jiri Olsa Link: https://lore.kernel.org/r/20221025134148.3300700-8-jolsa@kernel.org Signed-off-by: Alexei Starovoitov

bpf/selftests: Add test for writable bare tracepoint

2021-10-08T20:22:57+00:00

Add a writable bare tracepoint in bpf_testmod module, and trigger its calling when reading /sys/kernel/bpf_testmod with a specific buffer length. The reading will return the value in writable context if the early return flag is enabled in writable context.

selftests/bpf: Add test for bpf_get_branch_snapshot

2021-09-13T17:53:50+00:00

This test uses bpf_get_branch_snapshot from a fexit program. The test uses a target function (bpf_testmod_loop_test) and compares the record against kallsyms. If there isn't enough record matching kallsyms, the test fails.

selftests/bpf: Test that module can't be unloaded with attached trampoline

Adding test to verify that once we attach module's trampoline, the module can't be unloaded. Signed-off-by: Jiri Olsa Signed-off-by: Alexei Starovoitov Acked-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20210414195147.1624932-7-jolsa@kernel.org

selftests: bpf: Add a new test for bare tracepoints

2021-01-20T22:14:05+00:00

Reuse module_attach infrastructure to add a new bare tracepoint to check we can attach to it as a raw tracepoint. Signed-off-by: Qais Yousef Signed-off-by: Alexei Starovoitov Acked-by: Yonghong Song Link: https://lore.kernel.org/bpf/20210119122237.2426878-3-qais.yousef@arm.com

selftests/bpf: Add set_attach_target() API selftest for module target
