aya-obj v0.1.0

New Features

• Rename Bpf to Ebpf
  And BpfLoader to EbpfLoader.
  This also adds type aliases to preserve the use of the old names, making
  updating to a new Aya release less of a burden. These aliases are marked
  as deprecated since we'll likely remove them in a later release.

Other

• revamp MapInfo be more friendly with older kernels
  Adds detection for whether a field is available in MapInfo:

  • For map_type(), we treturn new enum MapType instead of the integer
    representation.
  • For fields that can't be zero, we return Option<NonZero*> type.
  • For name_as_str(), it now uses the feature probe bpf_name() to
    detect if field is available.
    Although the feature probe checks for program name, it can also be
    used for map name since they were both introduced in the same commit.

• revamp ProgramInfo be more friendly with older kernels
  Purpose of this commit is to add detections for whether a field is
  available in ProgramInfo.

  • For program_type(), we return the new enum ProgramType instead of
    the integer representation.
  • For fields that we know cannot be zero, we return Option<NonZero*>
    type.
  • For name_as_str(), it now also uses the feature probe bpf_name()
    to detect if field is available or not.
  • Two additional feature probes are added for the fields:
    • prog_info_map_ids() probe -> map_ids() field
    • prog_info_gpl_compatible() probe -> gpl_compatible() field

  With the prog_info_map_ids() probe, the previous implementation that
  I had for bpf_prog_get_info_by_fd() is shortened to use the probe
  instead of having to make 2 potential syscalls.

  The test_loaded_at() test is also moved into info tests since it is
  better related to the info tests.

• add conversion u32 to enum type for prog, link, & attach type
  Add conversion from u32 to program type, link type, and attach type.
  Additionally, remove duplicate match statement for u32 conversion to
  BPF_MAP_TYPE_BLOOM_FILTER & BPF_MAP_TYPE_CGRP_STORAGE.

  New error InvalidTypeBinding<T> is created to represent when a
  parsed/received value binding to a type is invalid.
  This is used in the new conversions added here, and also replaces
  InvalidMapTypeError in TryFrom for bpf_map_type.

• add archs powerpc64 and s390x to aya
  bpfman, a project using aya, has a requirement to support powerpc64 and
  s390x architectures. Adding these two architectures to aya.

• Generate new bindings

Test

• adjust test to not use byte arrays
  Where possible, replace the hardcoded byte arrays in the tests with the
  structs they represent, then convert the structs to byte arrays.
• adjust test byte arrays for big endian
  Adding support for s390x (big endian architecture) and found that some
  of the unit tests have structures and files implemented as byte arrays.
  They are all coded as little endian and need a bug endian version to
  work properly.

• Rename BpfRelocationError -> EbpfRelocationError
