selftests/bpf: Add tests for extending sleepable global subprogs

2025-03-15T18:48:25+00:00

Add tests for freplace behavior with the combination of sleepable and non-sleepable global subprogs. The changes_pkt_data selftest did all the hardwork, so simply rename it and include new support for more summarization tests for might_sleep bit.

selftests/bpf: extend changes_pkt_data with cases w/o subprograms

2024-12-12T19:38:36+00:00

Extend changes_pkt_data tests with test cases freplacing the main program that does not have subprograms. Try four combinations when both main program and replacement do and do not change packet data.

selftests/bpf: freplace tests for tracking of changes_packet_data

2024-12-10T18:24:57+00:00

Try different combinations of global functions replacement: - replace function that changes packet data with one that doesn't; - replace function that changes packet data with one that does; - replace function that doesn't change packet data with one that does; - replace function that doesn't change packet data with one that doesn't; Signed-off-by: Eduard Zingerman Link: https://lore.kernel.org/r/20241210041100.1898468-7-eddyz87@gmail.com Signed-off-by: Alexei Starovoitov
