Friday Ortiz	ab38afe95d	perf_event: support hardware breakpoints ... Implement `PerfEventConfig::Breakpoint`, allowing users to attach hardware breakpoints. Generate `HW_BREAKPOINT_*` and `struct bpf_perf_event_data` in support of this feature and update the type of `PerfEventContext` accordingly. Add a test exercising R, W, RW, and X breakpoints. Note that R breakpoints are unsupported on x86, and this is asserted in the test. Extend the VM integration test harness and supporting infrastructure (e.g. `download_kernel_images.sh`) to download kernel debug packages and mount `System.map` in initramfs. This is needed (at least) on the aarch 6.1 Debian kernel which was not compiled with `CONFIG_KALLSYMS_ALL=y` for some reason, and the locations of globals are not available in kallsyms. To attach breakpoints to these symbols in the test pipeline, we need to read them from System.map and apply the KASLR offset to get their real address. The `System.map` file is not provided in the kernel package by default, so we need to extract it from the corresponding debug package. The KASLR offset is computed using `gunzip` which appears in kallsyms on all Debian kernels tested. Co-authored-by: Tamir Duberstein <tamird@gmail.com>	7 days ago
Tamir Duberstein	d1f2e99e6a	xtask: release mode ... Since a7cfc694bd we are unpacking dpkg archives in native Rust and since ... we are downloading and unpacking debug archives which are around 10x larger than kernel archives for the same version. Thus build with optimizations so we spend less time in archive extraction.	7 days ago
Tamir Duberstein	0484ab5c57	xtask: use `-cpu host` iff host == guest	7 days ago
Tamir Duberstein	fd18c3f4ab	.github: shard arm64 virtualized integration ... Github arm64 runners don't support nested virtualization and they broke nested virtualization on macos-15-intel so we must go nuclear.	7 days ago
Tamir Duberstein	e2f09ac62f	.github: move comments to Brewfile ... This is where the dependencies are.	7 days ago
Tamir Duberstein	7288a2b8da	.github: remove stale comment ... GNU tar is not needed since 5f046899b5.	7 days ago
JPaja	d8f5497884	feat: add `Ebpf::maps_disjoint_mut` ... Implemented using `HashMap::get_disjoint_mut` introduced in Rust 1.86.0.	7 days ago
Tamir Duberstein	65865e8dfc	.github: disable macos-15-intel ... These builds are timing out, see https://github.com/actions/runner-images/issues/13277.	7 days ago
Tamir Duberstein	989a465f0c	xtask: avoid extracting complete archives ... Now that we're no longer shelling out to do this, we can avoid most of the work. Operate directly on the archive, unpacking only what we need.	7 days ago
Tamir Duberstein	2b8cd557aa	xtask: drop build script logging prefix ... This code doesn't run under cargo.	1 week ago
Tamir Duberstein	112ab47fcd	Add clippy coverage for doctests	1 week ago
Tamir Duberstein	18c7f7ccd6	perf_event: push down type safety ... This makes it more difficult to mishandle callers of `perf_event_open`. Change `wakeup_events = 0` to 1; per `man 2 perf_event_open`: Prior to Linux 3.0, setting wakeup_events to 0 resulted in no overflow notifications; more recent kernels treat 0 the same as 1.	1 week ago

Tamir Duberstein	866cbe4837	all: bump MSRV to 1.87.0 ... Use newly stabilized `is_multiple_of`.	1 week ago
Tamir Duberstein	468b9b73db	xtask: use `-cpu host` on x86 ... We have started to see errors in CI: qemu-system-x86_64: warning: host doesn't support requested feature: CPUID[eax=80000001h].ECX.svm [bit 2] The internet says this is the remedy.	1 week ago
swananan	4fbce44b6a	aya: tolerate proc map trailing newline ... Proc maps terminate with a newline so split(b'\n') yields an empty slice at the end. Filter it out before parsing so the absolute-path fallback for pid-scoped attach doesn't get short-circuited by a ProcMap::ParseLine error.	2 weeks ago
Tim W	17573e0e47	aya-build: plumb features of ebpf crates ... This allows callers to select features of the ebpf crate.	2 weeks ago
Tamir Duberstein	948b8553ee	aya-build: guess `bpf_target_arch` from `HOST` ... Remove the use of `CARGO_CFG_TARGET_ARCH` in ebpf crate build scripts, moving it back only to `aya_build::build_ebpf` where it refers to the userspace crate's target. In the ebpf crates restore the use of `HOST` as the default compilation target when neither `--cfg bpf_target_arch` nor `AYA_BPF_TARGET_ARCH` are provided.	3 weeks ago
Tamir Duberstein	fe3f5c4e7d	aya-build: read AYA_BPF_TARGET_ARCH ... This allows users to set `bpf_target_arch` from the environment without touching RUSTFLAGS.	3 weeks ago
Tamir Duberstein	4b0ddfc2b0	aya-build: simplify ... Cargo sets `CARGO_CFG_BPF_TARGET_ARCH` so we don't have to inspect `CARGO_ENCODED_RUSTFLAGS`.	3 weeks ago

Alessandro Decina	3a3c451009	aya: restore must_exist argument to set_global ... In 03e8487177 we deprecated set_global but accidentally broke its API by deleting the must_exist argument.	3 weeks ago
Tamir Duberstein	03fea9e304	aya-ebpf: reduce duplication	3 weeks ago
Tamir Duberstein	b4bcf52ef1	aya-build: pass bpf_target_arch with cfg ... Retire the use of `CARGO_CFG_BPF_TARGET_ARCH` -- using a `cfg` allows cargo to properly use a cache per cfg, making `./clippy.sh` much faster. ``` Cold: ./clippy.sh --target x86_64-unknown-linux-gnu -p aya-build 75.38s user 137.28s system 211% cpu 1:40.43 total Warm: ./clippy.sh --target x86_64-unknown-linux-gnu -p aya-build 4.46s user 3.41s system 71% cpu 11.01 total ```	3 weeks ago

Tamir Duberstein	e5eb3058aa	.github: save CI time ... These jobs take 18 seconds of machine time and 21 seconds of setup; consolidate them into one job to cut down on the overhead.	3 weeks ago
Tamir Duberstein	05250da20b	aya-ebpf: reduce repetition and excessive traits ... The traits `FromBtfArgument`, `FromRawTracepointArgs`, `FromPtRegs` are all fancy ways of saying `Argument` - so replace these traits with it. This also removes the use of `bpf_probe_read` which was introduced in 05c1586202 because I can't reproduce the need for it.	3 weeks ago
Godones	4b4b9f83bd	enable bpf_target_arch = loongarch64 ... Signed-off-by: Godones <chenlinfeng25@outlook.com> Signed-off-by: Tamir Duberstein <tamird@gmail.com>	3 weeks ago
Tamir Duberstein	9e577f60b5	integration-test: remove `netns-rs` ... This crate uses a very old version of `nix` which is preventing us from adding support for loongarch64. Make panic-in-panic more uniform while I'm here.	3 weeks ago
Tamir Duberstein	12d963ddfd	brewfile: remove dpkg ... This is unused since a7cfc694bd.	3 weeks ago
Michal R	a7cfc694bd	xtask: Allow to run VM integration tests without dpkg ... Debian packages are just nested archives, where the outer one is ar and the inner one is lzma2 tarball. Use Rust crates to unpack them. Co-authored-by: Tamir Duberstein <tamird@gmail.com>	4 weeks ago
