Tamir Duberstein	e9a099f332	bpf: Remove builtin global functions ... This commit removes memset and memcpy, relying instead on implementations provided by std/compiler-builtins. This commit adds `#![no_builtins]` to all the BPF programs written in Rust, and the same should be propagated to aya-template and all examples in the book and elsewhere before this commit is merged. It turns out that without the `#![no_builtins]` annotation rustc generates LLVM IR that calls LLVM intrinsics rather than libcalls. These may end up as libcalls after lowering, but not before emitting errors in BPF lowering[0]. This works thanks to https://github.com/rust-lang/rust/pull/113716 which causes `#![no_builtins]` to behave similarly to `-fno-builtin` in clang, which was added in https://reviews.llvm.org/D68028 with similar motivation. This commit implies that we now require rustc nightly >= 2023-07-20. [0] https://github.com/llvm/llvm-project/blob/7b2745b/llvm/lib/Target/BPF/BPFISelLowering.cpp#L472-L474	2 years ago
Andrew Werner	e2cf734490	aya: Implement RingBuf ... This implements the userspace binding for RingBuf. Instead of streaming the samples as heap buffers, the process_ring function takes a callback to which we pass the event's byte region, roughly following [libbpf]'s API design. This avoids a copy and allows marking the consumer pointer in a timely manner. [libbpf]: https://github.com/libbpf/libbpf/blob/master/src/ringbuf.c Additionally, integration tests are added to demonstrate the usage of the new APIs and to ensure that they work end-to-end.

Dave Tucker	f833f1fc1d	xtask: Add cargo-public-api ... Adds cargo-public-api. This allows for public API changes to get caught in CI, requiring new changes to be "blessed" by using: cargo xtask public-api --bless When this file is changed for aya, Alessandro will need to review the PR.
