Dave Tucker	686ce45f93	aya: Fix BTF type resolution for Arrays and Ints ... The union of `size` and `type` is unused in BTF_KIND_ARRAY. Type information of elements is in the btf_array struct that follows in the type_ field while the index type is in the index_type field. For BTF_KIND_INT, only the offset should be compared and size and signedness should be ignored. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Dave Tucker	5c6131afba	Add BPF_PROG_TYPE_EXT ... This requires loading the BTF to kernel when loading all programs as well as implementing Extension program type Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	379bb313b1	obj: Add Btf::to_bytes ... This allows for parsed BTF to be re-encoded such that it could be loaded in to the kernel. It moves bytes_of to the utils package. We could use Object::bytes_of, but this requires the impl of the Pod trait on generated code. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Michal Rostecki	54377b6140	aya-bpf: Allow to convert probe arguments to mutable pointers ...

Dave Tucker	65a0b83205	Mark .rodata maps as readonly and freeze on load ... This commit marks .rodata maps as BPF_F_RDONLY_PROG when loaded to prevent a BPF program mutating them. Initial map data is populated by the loader using the new `BpfLoader::set_global()` API. The loader will mark is marked as frozen using bpf_map_freeze to prevent map data being changed from userspace. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Michal Rostecki	7e2fcd1d6d	Support for fentry and fexit programs ... fentry and fexit programs are similar to kprobe and kretprobe, but they are newer and they have practically zero overhead to call before or after kernel function. Also, fexit programs are focused on access to arguments rather than the return value. Those kind of programs were introduced in the following patchset: https://lwn.net/Articles/804112/ Signed-off-by: Michal Rostecki <mrostecki@opensuse.org>	3 years ago
