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.

astoycos	7b71c7e1cd	aya/maps: add pin() api ... - Adds new `maps_mut()` API to the BpfManager to allow us to iterate though and pin all of maps at the same time. - Adds new pin(Path)/unpin(Path) api to Maps so they can be generically pinned AFTER load. - Adds macro for pinning explicit map types in aya. Convert all explicit map types "inner" field to be pub crate in order to facilitate this. Signed-off-by: astoycos <astoycos@redhat.com>	2 years 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.

Andrew Stoycos	0b6ea313de	Merge pull request #782 from astoycos/prog-info ... aya: add program_info() api to `Program`	2 years 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.	2 years ago

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.	2 years ago
Tamir Duberstein	8b0c7f1204	async_perf_event_array: access inner through async ... Avoid holding onto raw file descriptors. Remove some implied bounds (BorrowMut implies Borrow).	2 years ago
Andrés Medina	6895b1e2ed	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.	2 years ago

Tamir Duberstein	89bc255f1d	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.	2 years ago

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.

Previously bpf-linker changes would rebuild integration-test, but not integration-ebpf, resulting in stale tests. Note that this still doesn't address the possibility that a new bpf-linker is added to the PATH ahead of the cached one. Solving this in the general case would require rebuild-if-changed-env=PATH *and* rebuild-if-changed={every-directory-in-PATH} which would likely mean far too much cache invalidation.	2 years ago

This eases the user-experience so that users don't need to think about the submodule, while retaining all the benefits of using a submodule vs forcing the user to manually check out libbpf and stick it in some pre-defined place. We use the symbol pointing to libbpf in xtask in the build script to avoid repeating this constant. Also, we install git in the vm so that we can init the submodule when we build in the vm.	2 years ago

Tamir Duberstein	6ac1320707	integration-test: build "fake" by default ... Use the environment variable AYA_BUILD_INTEGRATION_BPF to indicate to the build script that it should *actually* build bpf, otherwise emitting empty files. This allows metadata builds to skip costly build steps without sacrificing ergonomics; all compile-time tools such as cargo clippy work out of the box. Cargo even gives each of these builds (depending on the value of the environment variable) its own cache key, so they do not invalidate each other when the user alternates between metadata and real builds. This allows the lint action to move out of the VM.	2 years ago

Kenjiro Nakayama	8c8d236f42	xtask: codegen: generate bindings for user_regs_struct ... This patch adds `user_regs_struct`. riscv provides struct user_regs_struct instead of struct pt_regs to userspace. After bindings generates the code, adding the riscv support in `bpf/aya-bpf/src/args.rs` then aya-bpf can be built for riscv.	3 years ago

Dave Tucker	dc31e11691	Re-organize into a single workspace ... This commit moves the aya-log projects from the subtree and adds them to the main cargo workspace. It also brings the BPF crates into the workspace and moves the macro crates up a level since they aren't BPF code. Miri was disabled for aya-bpf as the previous config wasn't actually checking anything. CI, clippy, fmt and release configurations have all been adjusted appropriately. CI was not properly running for other supported arches which was also ixed here. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	79101e748a	test: Replace RTF with Rust ... This commit replaces the existing RTF test runner with a simple rust binary package called - integration-test. integration-test depends on integration-ebpf, which contains test eBPF code written in Rust and C. `cargo xtask build-integration-test-ebpf` can be used to build this code and supress rust-analyzer warnings. It does require `bpf-linker`, but that is highly likely to be available to developers of Aya. It also requires a checkout of `libbpf` to extract headers like bpf-helpers.h. Since everything is compiled into a single binary, it can be run be run locally using `cargo xtask integration-test` or remotely using `./run.sh` which re-uses the bash script from the old test framework to spawn a VM in which to run the tests.

Kenjiro Nakayama	200d42e414	xtask: Add `bpf_.*` instead of `bpf_map_.*` to allowed type ... This patch replaces `bpf_map_.*` with `bpf_.*`. Currently some types that are not used in helper functions are not generated for bindings - e.g. `bpf_sk_lookup`, `bpf_sockopt` and etc. This patch replaces `bpf_map_.*` with `bpf_.*`. Note, this PR does not include bindings files as it would be better to be created by auto script. The missing bindings can be created by `cargo xtask codegen --libbpf-dir /<PATH_TO>/libbp`.	4 years ago
