astoycos	b1769678f4	aya/maps: pin for (async)perf_event_array ... Implement pinning for perf_event_array and async_perf_event_array. Additionally make the core MapData.pin method operate on a reference rather than a mutable reference. Signed-off-by: astoycos <astoycos@redhat.com>	2 years ago
Andrew Werner	c06fcc3eda	maps/ringbuf: make RingBuf: Send + Sync ... There was no reason for them not to be -- the APIs all require mutable references and hold onto mutable references, so there cannot be internal concurrency. The !Send + !Sync came from the MMap, but not for any good reason.	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.

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
Tamir Duberstein	5392f9821d	xtask: terminate QEMU on "BUG: soft lockup" ... See https://github.com/aya-rs/aya/actions/runs/6329828507/job/17190931752. Unlike on kernel panic this message prints periodically so it is permitted to print twice before QEMU is killed.	2 years ago

Dave Tucker	42fd82e32b	Merge pull request #790 from dave-tucker/no-map-pinned	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. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	2 years ago
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
astoycos	6ab7475fa6	aya: add program_info() api to program ... Add a new api to the outer level `Program` structure which allows users to get the program's kernel info before casting it to an explicit program variant. Signed-off-by: astoycos <astoycos@redhat.com>	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	782eb85d4a	xtask: extract `Errors` type ... This produces better errors in `cargo xtask public-api` because before this change we'd print errors as display, which didn't show context.

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
