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	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.

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
