2024-09-04selftests: bpf: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZEFeng Yang1-1/+2
The ARRAY_SIZE macro is more compact and more formal in linux source. Signed-off-by: Feng Yang <[email protected]> Signed-off-by: Andrii Nakryiko <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
2023-12-04selftests/bpf: Test outer map update operations in syscall programHou Tao1-5/+91
Syscall program is running with rcu_read_lock_trace being held, so if bpf_map_update_elem() or bpf_map_delete_elem() invokes synchronize_rcu_tasks_trace() when operating on an outer map, there will be dead-lock, so add a test to guarantee that it is dead-lock free.

Improve selftest to check that btf_load is working from bpf program. Signed-off-by: Alexei Starovoitov <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Acked-by: Andrii Nakryiko <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
2021-05-19selftests/bpf: Test for syscall program typeAlexei Starovoitov1-0/+71
bpf_prog_type_syscall is a program that creates a bpf map, updates it, and loads another bpf program using bpf_sys_bpf() helper.
