Tamir Duberstein	56ebe1406e	aya-tool: do not attempt to run rustfmt ... This can be done externally. Do so in CI. This is an attempt to resolve the inconsistency between CI and local rustfmt in the generated bindings. Restore running CI on generated branches; the presence of a PR is apparently not enough.	8 months ago
Tamir Duberstein	f0a9f19ddc	Bump edition to 2024 ... Change FromRawTracepointArgs::arg to return T rather than *const T which seems to have been returning a dangling pointer. Arguably this is not strictly necessary; edition 2024 seems to be focused on increased strictness around unsafe code which doesn't unlock new functionality for our users. That said, this work revealed an apparent bug (see above) that we wouldn't otherwise catch due to allow-by-default lints.	8 months ago
Tamir Duberstein	4101a5a55d	Use #[expect(...)] rather than #[allow(...)] ... This is stricter, and revealed a few unused allowances.	8 months ago

Dave Tucker	d92284e4f8	chore(codegen): Fix duplicate BPF_F_LINK ... Per the comment added in the code, there are 2 definitions of BPF_F_LINK in the kernel headers. Once is in an anonymous enum which bindgen will constify, and once is via a #define macro. The values are identical. The fix is to exclude BPF_F_LINK from the list of variables in bindgen removing one of the duplicate definitions. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	9 months ago

Tamir Duberstein	d1457acc6d	ci: cache downloads ... We're seeing 429 from Github trying to download gen_init_cpio, so cache it using actions cache. Since I'm here add this for kernel images as well to save time waiting on slow Debian servers.	10 months ago
Tamir Duberstein	cc2da4a2a4	ci: download gen_init_cpio with authentication ... The raw endpoint[0] now[1] seems to return HTTP 429 on the first request and unauthenticated API limits are exceeded after one request (so one of ubuntu/macos builders fails). Hopefully this works with authentication.

Tamir Duberstein	fd00b39f09	Enable unwinding in userspace ... Unwinding gives us more information, so we shouldn't disable it globally. It is already disabled for BPF targets via the target configs in rustc itself. This complicates the clippy invocation somewhat, so put it in a shell script for developer as well as CI use.	11 months ago

tyrone-wu	b23973dd9c	xtask: corrected bpf to ebpf for path to aya-ebpf-bindings in codegen ... Currently, when running `cargo +nightly xtask codegen` locally and in the codegen GHA workflow, an error occurs with only "Error: bindgen failed" displayed. This was due to a path using "bpf/..." instead of "ebpf/...". It is now corrected to "ebpf", and bindgen fails should now display a more direct message on why it failed. Fixes: #914	2 years ago

Tamir Duberstein	e276c07f73	integration-ebpf: invalidate on bpf-linker ... Extract the symlink-to-bpf-linker logic from integration-test to xtask and use it in a new build script in integration-ebpf, causing ebpf probes to be rebuilt when bpf-linker changes. Previously bpf-linker changes would rebuild integration-test, but not integration-ebpf, resulting in stale tests. Note that this still doesn't address the possibility that a new bpf-linker is added to the PATH ahead of the cached one. Solving this in the general case would require rebuild-if-changed-env=PATH *and* rebuild-if-changed={every-directory-in-PATH} which would likely mean far too much cache invalidation.	2 years ago
