Alexei Starovoitov	7f0059b58f	selftests/bpf: Fix kprobe_multi test. ... When compiler emits endbr insn the function address could be different than what bpf_get_func_ip() reports. This is a short term workaround. bpf_get_func_ip() will be fixed later. Signed-off-by: Alexei Starovoitov <ast@kernel.org>	2022-03-22 11:09:13 -07:00
Jiri Olsa	2c6401c966	selftests/bpf: Add kprobe_multi bpf_cookie test ... Adding bpf_cookie test for programs attached by kprobe_multi links.

Jiri Olsa	f7a11eeccb	selftests/bpf: Add kprobe_multi attach test ... Adding kprobe_multi attach test that uses new fprobe interface to attach kprobe program to multiple functions. The test is attaching programs to bpf_fentry_test* functions and uses single trampoline program bpf_prog_test_run to trigger bpf_fentry_test* functions.
