Tuetuopay	b6963cb6bc	maps/xdp: use ProgramFd instead of impl AsRawFd ... Not having a generic here allows to pass `None` without specifying the actual type you don't care about.	2 years ago
Tuetuopay	23777ea567	bpf: add documentation for XDP maps	2 years ago
Tuetuopay	e4c715a789	aya: fix docstring missing trailing period	2 years ago
Tuetuopay	784691299e	xdp: add support for chained xdp programs in {cpu,dev}map ... set/insert functions can now take an optional bpf program fd to run once the packet has been redirected from the main probe	2 years ago
Tuetuopay	c753d1c45a	aya: add support for map-bound XDP programs ... Such programs are to be bound to cpumap or devmap instead of the usual network interfaces.	2 years ago
Tuetuopay	6350709115	aya: Update XDP maps implementations ... Map impls changed since this was first written. Fixes: 2b726c8 ("aya: Implement XDP Map Types")	2 years ago
Dave Tucker	125257780b	aya: Implement XDP Map Types ... This commit adds implementations for: - xskmap - devmap - devmap_hash - cpumap Which can all be used to redirect XDP packets to various different locations Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	2 years ago
Tamir Duberstein	1ccfdbc175	aya: support non-UTF8 probing ... Fixes #751.	2 years ago
Tamir Duberstein	0bba9b14b0	maps,programs: avoid path UTF-8 assumptions	2 years ago
Tamir Duberstein	572d047e37	test: avoid lossy string conversions ... We can be strict in tests.	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	9ff1bf3d3b	aya: fix docs build ... Appease the new lint rustdoc::redundant_explicit_links that was added in https://github.com/rust-lang/rust/pull/113167.	2 years ago
Tamir Duberstein	a31544b6e7	maps: BloomFilter::insert takes &mut self ... This is consistent with all the other maps.	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
Tamir Duberstein	3d68fa32cb	aya: use RAII to close FDs	2 years ago
Tamir Duberstein	ae6526e59b	programs: `ProgramData::attach_prog_fd` is owned ... This prevents a file descriptor leak when extensions are used. This is an API breaking change. Updates #612.	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	bcc9743254	Merge pull request #637 from astoycos/helpers ... Add more helpful methods to `ProgramInfo`	2 years ago
Andrew Stoycos	e1a556894c	aya: add helper methods for ProgramInfo ... - Add helper methods to get useful information from the ProgramInfo object which is returned by the `loaded_programs()` API. Specifically this code mirrors the `bpftool prog` command in terms of useful fields. - Add a new API macro to each aya `Program` type to allow us to fetch its accompanying `ProgramInfo` metadata after its been loaded. - Add a new ProgramInfo constructor that builds a new instance using a raw fd. - Add a smoke test for the loaded_programs() API as well as all the relevant methods on the ProgramInfo type.

Dave Tucker	03c5012db2	Merge pull request #702 from dave-tucker/mapdata-btffd ... aya: Don't store btf_fd in MapData	2 years ago
Tamir Duberstein	d88ca62aaa	programs: Plug attach_btf_obj_fd leak ... `ProgramData::attach_btf_obj_fd` is now owned. This means that `ProgramData` now closes the file descriptor on drop. Updates #612.	2 years ago
Dave Tucker	db975e9778	aya: Don't store bpf_fd in MapData ... This is only used in create and therefore can be passed as a parameter. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	2 years ago
Tamir Duberstein	5ac186299b	sys: refactor btf_obj_get_info_by_fd to share code	2 years ago
Tamir Duberstein	c7a19bcefb	sys: add map_ids to bpf_prog_get_info_by_fd ... Allows the caller to pass a slice which the kernel will populate with map ids used by the program.	2 years ago
Tamir Duberstein	5138c731a9	util: avoid vector allocation when parsing ksyms	2 years ago
Addison Crump	ed777273b1	nuclear option: no symbol resolution in the crate	2 years ago
Dave Tucker	e38e2566e3	aya, aya-obj: Implement ENUM64 fixups ... This commit adds: - A probe to see if the ENUM64 feature is supported - Fixups for the use of signed enums, or enum64 types on systems where enum64 is not supported Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	2 years ago

Addison Crump	d8709de9f2	Extract trait SymbolResolver	2 years ago
Dave Tucker	cca9b8f1a7	aya-obj: Remove name from ProgramSection ... The name here is never used as we get the program name from the symbol table instead. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	2 years ago
Andrew Werner	81fb4e5568	uprobe: refactor target resolution ... This attempts to do fewer lossy conversions and to avoid some allocations.	2 years ago

Dave Tucker	77e9603976	Merge pull request #711 from dave-tucker/sleepable ... Tidy up aya-bpf-macros (again)	2 years ago
Andrew Werner	dcc6b84a88	programs/uprobe: extract library path resolving ... The function is extracted so that a test could be written. This test is valid on linux-gnu targets, and it doesn't need any special privileges. This is in anticipation of removing the code that uses this functionality (seemingly incidentally) from integration tests.	2 years ago
Tamir Duberstein	368ddf10c4	Merge pull request #712 from aya-rs/loaded-links ... integration-test: remove bpftool dependency	2 years ago
Tamir Duberstein	30faa5f68f	Add links iterator ... This is not yet exposed in documentation, but is complete enough for use in tests, removing the dependency on bpftool. Updates #645.	2 years ago

Tamir Duberstein	4cb3ea6e8f	sys: `sys_bpf` takes mut ref ... Some syscalls mutate the argument, we can't be passing an immutable reference here.	2 years ago
