Andrew Werner	628b7fb022	aya::programs::uprobe: add support for cookies ... Fixes #1132. Note that this change does not add support in the public API for kprobes or tracepoints, but it's a trivial matter of plumbing. Along the way, the Uprobe::attach API is cleaned up to make the attachment location more coherent. The logic being: if we're going to be breaking the API anyway, may as well clean it up a bit. Furthermore, the aya::sys::bpf_link_attach function is cleaned up by properly modeling the the union in the final field with a rust enum.	3 months ago

Dave Tucker	8c79b71bd5	feat(aya): Rename Bpf to Ebpf ... And BpfLoader to EbpfLoader. This also adds type aliases to preserve the use of the old names, making updating to a new Aya release less of a burden. These aliases are marked as deprecated since we'll likely remove them in a later release. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	1 year ago

Andrés Medina	d2e74e562d	aya: Use BorrowedFd when using the program fd in sys/bpf.rs ... This commit reveals but does not address a file descriptor leak in LircLink2::query. This function returns a list of `LircLink`s where each of them have a program file descriptor that is not going to be closed. This commit does not add this leak; it merely makes it louder in the code.	2 years ago

Tamir Duberstein	abda239d63	aya: deny various allow-by-default lints ... Notably: - clippy::use_self: replaced many T with Self. - single_use_lifetimes: removed some single use lifetimes. - unreachable_pub: removed some unreachable pub items. - unused_crate_dependencies: removed unused futures,parking_lot deps. - unused_qualifications: found a potential `crate` vs `$crate` bug. - let_underscore_drop: not enabled, seems to trigger false positives. - missing_copy_implementations: not enabled, unclear if we want this. - unsafe_op_in_unsafe_fn: not enabled, unclear if we want this. - unused_results: not enabled, needs many fixes (but I think wanted).	2 years ago
Tamir Duberstein	504fd1df0a	programs: `ProgramFd` is owned ... `ProgramData::fd` is now a `ProgramFd`. This means that `ProgramData` now closes the file descriptor on drop. In the future we might consider making `ProgramFd` hold a `BorrowedFd` but this requires API design work due to overlapping borrows. Since `ProgramFd` is no longer `Copy`, update methods to take it by reference to allow callers to use it multiple times as they are accustomed to doing. `ProgramFd` is now returned by reference and implements `try_clone` to allow callers to avoid file descriptor cloning when desired. This is an API breaking change. Updates #612.	2 years ago

Andrew Stoycos	58895db9b4	Implement FdLink conversions ... Implement TryFrom functions to convert Fdlink to PerfLink/TracePointLink/ KprobeLink, and UprobeLink and vice-versa. This allows us to pin taken links for perf programs, ultimately ensuring the link isn't dropped when the loading process exits. Signed-off-by: Andrew Stoycos <astoycos@redhat.com>	2 years ago

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

Dave Tucker	9426f36f79	Implement Pinning For Programs and Maps ... This commit adds 2 new methods to aya::sys - bpf_pin_object - bpf_get_object Which allow the pinning and retrieval of programs/maps to bpffs. It adds a `Program.pin` API, such that a loaded program can be pinned. For map pinning, the user must ensure the `pinning u32` in the `bpf_map_def` is set to 1, maps will be pinned using a new builder API. BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o") This will pin all maps whose definition requests pinning to path + name.
