selftest/bpf: Replace magic constants by macros

2024-12-13T22:48:39Z

Replace magic constants in a BTF structure initialization code by proper macros, as is done in other similar selftests. Suggested-by: Eduard Zingerman Signed-off-by: Anton Protopopov Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20241213130934.1087929-8-aspsk@isovalent.com

selftests: bpf: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE

2024-09-04T19:58:46Z

The ARRAY_SIZE macro is more compact and more formal in linux source. Signed-off-by: Feng Yang Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20240903072559.292607-1-yangfeng59949@163.com

selftests/bpf: Test outer map update operations in syscall program

2023-12-05T01:50:27Z

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.

selftests/bpf: Test for syscall program type

2021-05-18T22:33:40Z

bpf_prog_type_syscall is a program that creates a bpf map, updates it, and loads another bpf program using bpf_sys_bpf() helper.
