Alessandro Decina	cb57d10d25	aya: rework links ... Remove LinkRef and remove the Rc<RefCell<_>> that was used to store type-erased link values in ProgramData. Among other things, this allows `Bpf` to be `Send`, which makes it easier to use it with async runtimes. Change the link API to: let link_id = prog.attach(...)?; ... prog.detach(link_id)?; Link ids are strongly typed, so it's impossible to eg: let link_id = uprobe.attach(...)?; xdp.detach(link_id); As it would result in a compile time error. Links are still stored inside ProgramData, and unless detached explicitly, they are automatically detached when the parent program gets dropped.	3 years ago

Alessandro Decina	ad1636d2e7	aya: perf_buffer: call BytesMut::reserve() internally ... This changes PerfBuffer::read_events() to call BytesMut::reserve() internally, and deprecates PerfBufferError::MoreSpaceNeeded. This makes for a more ergonomic API, and allows for a more idiomatic usage of BytesMut. For example consider: let mut buffers = vec![BytesMut::with_capacity(N), ...]; loop { let events = oob_cpu_buf.read_events(&mut buffers).unwrap(); for buf in &mut buffers[..events.read] { let sub: Bytes = buf.split_off(n).into(); process_sub_buf(sub); } ... } This is a common way to process perf bufs, where a sub buffer is split off from the original buffer and then processed. In the next iteration of the loop when it's time to read again, two things can happen: - if processing of the sub buffer is complete and `sub` has been dropped, read_events() will call buf.reserve(sample_size) and hit a fast path in BytesMut that will just restore the original capacity of the buffer (assuming sample_size <= N). - if processing of the sub buffer hasn't ended (eg the buffer has been stored or is being processed in another thread), buf.reserve(sample_size) will actually allocate the new memory required to read the sample. In other words, calling buf.reserve(sample_size) inside read_events() simplifies doing zero-copy processing of buffers in many cases.	3 years ago
