[PATCH 0/2] Improve error handling of verifier tests

These patches improve the error handling for verifier tests. With "Test the 32bit narrow read" Krzesimir Nowak provided these patches first, but they were never merged. The improved error handling helps to implement and test BPF program types that are not supported yet. Florian

[FIX bpf,perf] bpf,perf: return EOPNOTSUPP for bpf handler on PERF_COUNT_SW_DUMMY

. This fix returns the error EOPNOTSUPP to indicate that attaching a bpf handler to a perf event of type software/dummy is not supported. Signed-off-by: Florian Lehner --- kernel/events/core.c | 4 1 file changed, 4 insertions(+) diff --git a/kernel/events/core.c b/kernel/events/core.c
