Merge pull request #790 from dave-tucker/no-map-pinned 1 year ago
Dave Tucker 938f979fe7 aya: Make MapData::pin pub 
This is to solve a use-case where a user (in this case bpfd) may want
to:

- MapData::from_pin to open a pinned map from bpffs
- MapData::pin to pin that object into another bpffs

Both operations should be easily accomplished without needing to cast
a MapData into a concrete Map type - e.g aya::maps::HashMap.

Dave Tucker 0f4021ec89 aya: Remove MapData::pinned 
BPF objects can be pinned multiple times, to multiple different places.
Tracking whether or not a map is pinned in a bool is therefore not sufficient.
We could track this in a HashSet<PathBuf>, but there is really no reason
to track it at all.

aya: add program_info() api to `Program`
 1 year ago
Tamir Duberstein f41592663c
maps: `MapFd` and `SockMapFd` are owned 
`MapData::fd` is now a `MapFd`. This means that `MapData` now closes the
file descriptor on drop. In the future we might consider making `MapFd`
hold a `BorrowedFd` but this requires API design work due to overlapping
borrows.

Since `SockMapFd` is no longer `Copy`, attach methods to take it by
reference to allow callers to use it multiple times as they are
accustomed to doing.

`SockMapFd` implements `try_clone`. `MapFd` and `SockMapFd` are now
returned by reference to allow callers to avoid file descriptor cloning
when desired.

This is an API breaking change.

Updates #612.

async_perf_event_array: access inner through async

Andrew Werner 2a1bf609b2 aya/maps: rework TryFrom macros 
The old macros were repetitive and inflexible. This unifies the various
macros used to generate TryFrom implementations for map implementations
from the relevant map enum variants.

Cleanup in anticipation of fixing #636.

The API changes are just about renaming the return to Self and
Self::Error; they are not real changes.

aya: Use AsFd when attaching fds to programs 
This is a breaking change but adds another level of safety to ensure
the file descriptor we receive is valid. Additionally, this allows
aya to internally easily duplicate this file descriptor using std
library methods instead of manually calling `dup` which doesn't
duplicate with the CLOSE_ON_EXEC flag that is standard pratice to
avoid leaking the file descriptor when exec'ing.

aya: MapData::fd is non-optional 
The primary driver of change here is that `MapData::create` is now a
factory function that returns `Result<Self, _>` rather than mutating
`&mut self`. The remaining changes are consequences of that change, the
most notable of which is the removal of several errors which are no
longer possible.

Add more helpful methods to `ProgramInfo`

aya: add helper methods for ProgramInfo 
- Add helper methods to get useful information from the ProgramInfo
object which is returned by the `loaded_programs()` API.  Specifically
this code mirrors the `bpftool prog` command in terms of useful fields.
- Add a new API macro to each aya `Program` type to allow us to fetch
its accompanying `ProgramInfo` metadata after its been loaded.
- Add a new ProgramInfo constructor that builds a new instance using
a raw fd.
- Add a smoke test for the loaded_programs() API as well as
all the relevant methods on the ProgramInfo type.

Dave Tucker bf7fdff1ce aya: Find programs using the symbol table 
This makes a few changes to the way that Aya reads the ELF object
files.

1. To find programs in a section, we use the symbols table. This allows
   for cases where multiple programs could appear in the same section.
2. When parsing our ELF file we build symbols_by_section_index as an
   optimization as we use it for legacy maps, BTF maps and now programs.

As a result of theses changes the "NAME" used in `bpf.prog_mut("NAME")`
is now ALWAYS the same as the function name in the eBPF code, making the
user experience more consistent.
