Tamir Duberstein	e813a054ad	Merge pull request #744 from aya-rs/programfd-borrowed ... programs: `ProgramFd` is owned	1 year 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.	1 year ago

Tamir Duberstein	47a8a4b878	github: reduce wget verbosity, remove -q ... This allows errors to be shown; -q hides *all* output, which is not what we want.	1 year ago
Andrew Stoycos	bcc9743254	Merge pull request #637 from astoycos/helpers ... Add more helpful methods to `ProgramInfo`	1 year 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.

Tamir Duberstein	7e14214f47	xtask: add noapic to kernel parameters ... This might prevent some kernel panics.	1 year ago
Tamir Duberstein	de65ba0067	xtask: watch for kernel panic in stdout too ... Seems unclear whether kernel panics go to stdout or stderr, so do them both.	1 year ago

Tamir Duberstein	58ba66c003	xtask: watch for kernel panics on stderr ... It seems these go to stderr, not stdout. Use `Ctrl-A x` to shut QEMU down if a panic is seen.	1 year ago

Tamir Duberstein	ca3f70b16a	aya-log: s/Result<usize, ()>/Option<NonZeroUsize>/ ... `Option<NonZeroUsize>` is guaranteed to have the same size as `usize`, which is not guarnateed for `Result`. This is a minor optimization, but also results in simpler code.	1 year ago

Tamir Duberstein	3cfd886dc5	log: annotate logging functions inlining ... Some of these functions fail to compile when not inlined, so we should be explicit. Before deciding on this approach I tried various ways of making all these functions #[inline(never)] to save instructions but I ran into blockers: - These functions currently return Result, which is a structure. This is not permitted in BPF. - I tried inventing a newtype that is a #[repr(transparent)] wrapper of u16, and having these functions return that; however it seems that even if the object code is legal, the verifier will reject such functions because the BTF (if present, and it was in my local experiments) would indicate that the return is a structure. - I tried having these functions return a plain u16 where 0 means error, but the verifier still rejected the BTF because the receiver (even if made into &self) is considered a structure, and forbidden. We can eventually overcome these problems by "lying" in our BTF once support for it matures in the bpf-linker repo (e.g. Option<NonZeroU16> should be perfectly legal as it is guaranteed to be word-sized), but we aren't there yet, and this is the safest thing we can do for now.	1 year ago
Tamir Duberstein	fe047d79a3	aya-log-common: Simplify ... - Remove `TagLenValue`; this type has a single method, which is now a function. - Remove generics from `TagLenValue::write` (now `write`). The tag is always `u8`, and the value is always a sequence of bytes. - Replace slicing operations which can panic with calls to `get` which explicit check bounds.	1 year ago

Tamir Duberstein	71bc3ea0b5	integration-test: avoid reliance on kernel headers ... This should allow us to build on any system.	1 year ago
Tamir Duberstein	b46fb616be	integration-test: fix BTF relocation test ... The struct_flavors test previously expected the same thing with and without relocations. It now expects different values. Also rename an enum variant "u64" to "S64". This was a typo. Turns out that U32 is a type that exists in kernel headers, so all enum values are suffixed with "_VAL". Remove stdlib.h and the call to exit(). This alone makes the test fail with a poisoned relocation. Bringing over the map definition makes the test work again.	1 year ago
