Tamir Duberstein	5ac186299b	sys: refactor btf_obj_get_info_by_fd to share code	1 year 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.	1 year ago
Tamir Duberstein	5138c731a9	util: avoid vector allocation when parsing ksyms	1 year ago
Addison Crump	ed777273b1	nuclear option: no symbol resolution in the crate	1 year 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>	1 year ago
Andrés Medina	8ebf0ac327	aya: Use OwnedFd in FdLink.	1 year ago
Dave Tucker	e9153792f1	Merge pull request #720 from dave-tucker/programsection-noname ... aya-obj: Remove name from ProgramSection	1 year ago
Addison Crump	d8709de9f2	Extract trait SymbolResolver	1 year 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>	1 year ago
Andrew Werner	81fb4e5568	uprobe: refactor target resolution ... This attempts to do fewer lossy conversions and to avoid some allocations.	1 year ago
ajwerner	de8604d011	Merge pull request #717 from ajwerner/no-libc-in-integration-tests ... uprobe,integration-test: do not exercise dylib resolution in integration tests	1 year ago
Dave Tucker	77e9603976	Merge pull request #711 from dave-tucker/sleepable ... Tidy up aya-bpf-macros (again)	1 year 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.	1 year ago
Tamir Duberstein	368ddf10c4	Merge pull request #712 from aya-rs/loaded-links ... integration-test: remove bpftool dependency	1 year 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.	1 year ago
Dave Tucker	71737f5576	aya: Set BPF_F_SLEEPABLE for sleepable programs ... Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	1 year ago
Tamir Duberstein	89ef97e848	aya: preallocate the vector ... This code badly needs tests :(	1 year ago
Tamir Duberstein	7bb9b7f5a5	programs: plug file descriptor leak ... This leaked a file descriptor if bpf_prog_get_info_by_fd failed.	1 year ago
Tamir Duberstein	b1404e9a73	sys: push error construction up	1 year ago
Tamir Duberstein	a0af7e0b2f	programs: make `loaded_programs` opaque	1 year ago
Tamir Duberstein	de8519a380	sys: extract common SyscallError ... We currently have 4 copies of this.	1 year ago
Tamir Duberstein	4cb3ea6e8f	sys: `sys_bpf` takes mut ref ... Some syscalls mutate the argument, we can't be passing an immutable reference here.	1 year ago
Tamir Duberstein	7ee6f52a74	sys: avoid repeating BPF_BTF_LOAD dance	1 year ago
Tamir Duberstein	6f3cce75cf	test: s/assert!(.*) ==/assert_eq!\1,/ ... One case manually adjusted to `assert_matches!`.	1 year ago
Tamir Duberstein	0ec9afdb07	Reduce state cardinality from 4 to 2 ... Encode into the type system the fact that PerfLink::probe_kind and PerfLink::event_alias are present or absent together.	1 year ago
Andrés Medina	dbfba18dac	aya: Return `OwnedFd` for `perf_event_open`. ... This fixes a file descriptor leak when creating a link of BPF_PERF_EVENT attach type.	1 year ago
Tamir Duberstein	868a9b00b3	Merge pull request #704 from aya-rs/better-panic ... all: better panic messages	1 year ago
Tamir Duberstein	17f25a6793	all: better panic messages ... Always include operands in failing assertions. Use assert_matches over manual match + panic.	1 year ago
Tuetuopay	c74813f8c5	test: add the possibility to run a test inside a network namespace ... For tests that do networking operations, this allows to have a clean-state network namespace and interfaces for each test. Mainly, this avoids "device or resource busy" errors when reusing the loopback interface across tests.	1 year ago
Tamir Duberstein	8961be9526	Do not escape newlines on Err(LoadError).unwrap() ... Wrap verifier logs in a newtype whose `Debug` impl emits unescaped newlines. This improves ergonomics in tests where we `Result::unwrap()` those load errors; when these fail today they emit the errors with newlines escaped, making them incredibly difficult to read.	1 year ago
Andrés Medina	ea96c29ccb	aya: Use Arc<OwnedFd> when loading BTF fd ... This fixes an existing file descriptor leak when there is BTF data in the loaded object. To avoid lifetime issues while having minimal impact to UX the `OwnedFd` returned from the BPF_BTF_LOAD syscall will be wrapped in an `Arc` and shared accross the programs and maps of the loaded BPF file.	1 year ago
Andrés Medina	683a1cf2e4	aya: Make SysResult generic on Ok variant	1 year ago
Andrés Medina	c63d9904f7	Replace std::os::unix::io for std::os::fd ... This is just taking https://github.com/aya-rs/aya/pull/633 to its logical conclusion. Because `std::os::fd` was only introduced as a module in Rust v1.66.0 I have also updated the `Cargo.toml` of the `aya` package to reflect the true MSRV. Note that this commit is *not* the cause for this MSRV bump, that was done by a previous commit, this commit is just making it explicit in the `Cargo.toml`	1 year ago
Tamir Duberstein	76c78e3bf8	sys: bpf_prog_get_fd_by_id returns OwnedFd	1 year ago
Mike Rostecki	96fa08bd82	cargo: Define dependencies on the workspace level ... This way we will avoid version mismatches and make differences in features across our crates clearer.	1 year ago
Dave Tucker	764eb309b0	Clippy fixes for latest nightly ... Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	1 year ago
Tamir Duberstein	35ed85a87f	Handle WSL kernel version strings ... Fixes #654.	1 year ago
Tamir Duberstein	961f45da37	Replace matches with assert_matches ... The matches crate has been archived now that `matches!` is in std. However `assert_matches!` is still unstable in std, and the assert_matches crate provides a more expressive form: ``` assert_matches!(foo, Ok(bar) => { assert_eq!(bar, baz); }); ```	1 year ago
Tamir Duberstein	61608e6458	Merge pull request #650 from aya-rs/test-cleanup ... Remove async feature; misc test cleanup	1 year ago
Tamir Duberstein	5407d4a9a1	Don't use env::tempdir ... This can cause test pollution. Create a new temp directory on each run.	1 year ago
Tamir Duberstein	fa91fb4f59	Remove "async" feature ... This feature is equivalent to async_tokio || async_std; removing it avoids warnings emitted during `cargo hack check --feature-powerset` where async is selected without either of the other features. Use cargo hack to ensure clippy runs on the powerset of features.	1 year ago
Mary	74b546827c	aya: Ignore embedded BTF error if not truely required ... This allows fallback to BTF manual relocation when BTF loading fail when not truely required.	1 year ago
Alessandro Decina	242d8c33c4	Fix build	1 year ago
Alessandro Decina	eb60d65613	Merge pull request #520 from astoycos/unsupported-map ... Add Unsupported Map type	1 year ago
Andrew Stoycos	80b371f6d1	add FdLink documentation and example ... Signed-off-by: Andrew Stoycos <astoycos@redhat.com>	1 year 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>	1 year ago
Tamir Duberstein	8c61fc9ea6	integration-test: compile C probes using build.rs ... - Add libbpf as a submodule. This prevents having to plumb its location around (which can't be passed to Cargo build scripts) and also controls the version against which codegen has run. - Move bpf written in C to the integration-test crate and define constants for each probe. - Remove magic; each C source file must be directly enumerated in the build script and in lib.rs.	1 year ago
Tamir Duberstein	e621a09181	Clippy over tests and integration-ebpf ... Replace all `assert!(matches!(..))` with `assert_matches!(..)`. Remove the now-unused build-integration-test xtask command whose logic doesn't match that of the build-and-run command.	1 year ago
Tamir Duberstein	a1e0130387	Type-erase KernelVersion::current error	1 year ago
Tamir Duberstein	6bceb1c3da	Invert comparison ... Incorrectly inverted in b611038d5b.	1 year ago
