aya-obj: fix DATASEC to STRUCT conversion
2 years ago
Mary 4e33fa011e aya-obj: fix DATASEC to STRUCT conversion
This fix the following issues:
- Previously the DATASEC name wasn't sanitized resulting on "Invalid
  name" returned by old kernels.
- The newly created BTF struct had a size of 0 making old kernels refuse
  it.

This was tested on Debian 10 with kernel 4.19.0-21.

Fixes a crash when trying to create a map of type BPF_MAP_TYPE_PERCPU_ARRAY when btf_fd is None.

Tested on Ubuntu 18.04 (4.15.0-202-generic)

Alessandro Decina 401ea5e848 aya, aya-obj: refactor map relocations
Clearly split the code between `.maps`, `maps` and data maps (bss, data,
rodata). Sprinkle comments.

Remove MapKind which was effectively only needed since we used to have
one variant - BpfSectionKind::Data - to represent all data maps. Instead
add explicit BpfSectionKind::{Data, Rodata, Bss} variants and match on
those when we initialize maps.

Tuetuopay 3655cd1e02 tests: use fedora 38 beta with testing repo
Now that bpf-linker uses llvm 16, the easiest way is to use Fedora 38
Beta with the testing repos as they have it, without resorting to
Rawhide.

See https://packages.fedoraproject.org/pkgs/llvm/llvm/.

Dave Tucker ce79de7ff6 aya: Fix is_perf_link_supported
This was mistakenly comparing the exit code of the syscall, which is
always -1 and not the corresponding error-code. Added unit tests to
ensure we don't regress.
