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

Tyrone Wu	366c599c20	codegen: cgroup_iter_order NFPROTO* nf_inet_hooks ... Adds the following to codegen: - `bpf_cgroup_iter_order`: used in `bpf_link_info.iter.group.order` - `NFPROTO_*`: used in `bpf_link_info.netfilter.pf` - `nf_inet_hooks`: used in `bpf_link_info.netfilter.hooknum` Include `linux/netfilter.h` in `linux_wrapper.h` for `NFPROTO_*` and `nf_inet_hooks` to generate.	1 year ago

Shenghui Ye	81bc307dce	aya-obj: migrate bindgen destination ... Aya::obj depends on bindgen generated files, and we start by migrating bindgen generated files. This commit adds the new aya-obj crate to the workplace and migrates generated files into the crate. We use core instead of std in an effort to make the final crate no_std. Bindgen was run against libbpf v1.0.1. Refs: #473	3 years ago
