[Unreleased]

v0.1.2 (2025-11-17)

Breaking Changes

• Map helper functions now take *mut c_void, matching the kernel’s prototypes. Any out-of-tree helpers should update their signatures accordingly.

New Features

• Added a bpf_strncmp helper binding.
• Raw tracepoints now expose their arguments so programs no longer need to guess register layouts.
• , Added mips/loongarch register helpers so those targets can implement FromPtRegs.
• XdpContext exposes the interface index, simplifying multi-interface programs.
• Added Array::set() to update array contents from eBPF code.
• Introduced Flow Dissector program support on the eBPF side.
• Added RingBufBytes so probes can emit raw byte slices efficiently.
• , Added BTF array definitions plus Queue/Stack::peek() helpers for safer data-structure inspection.

Bug Fixes

• Fixed riscv64 builds by updating the generated bindings.
• Cleaned up ring-buffer code to avoid reliance on as casts, preventing UB on strict architectures.
• Guarded the libc mem* shims behind cfg(target_arch = "bpf"), ensuring CPU builds stay well-defined.

Maintenance

• , Added configuration flags for generic_const_exprs and the loongarch target, plus the usual lint/documentation refresh.

v0.1.1 (2024-10-09)

New Features

• Implement memmove The compiler will emit this function for certain operations, but aya currently does not provide an implementation. This leads to ebpf loading failures as the kernel can't find the symbol when loading the program.

  The implementation is based on https://github.com/rust-lang/compiler-builtins/blob/master/src/mem/mod.rs#L29-L40 and https://github.com/rust-lang/compiler-builtins/blob/master/src/mem/impls.rs#L128-L135 Only the simplest case has been implemented, none of the word optimizations, since memcpy also doesn't seem to have them.

Bug Fixes

• Remove PerfEventArray::with_max_entries This API doesn't make sense as the max_entries needs to be set to the number of online CPUs by the loader.

Other

• Add set_reply accessor to SockOpsContext
• add archs powerpc64 and s390x to aya bpfman, a project using aya, has a requirement to support powerpc64 and s390x architectures. Adding these two architectures to aya.
• moved ret from ProbeContext into new RetProbeContext Created retprobe.rs to hold RetProbeContext and moved the ret from ProbeContext in probe.rs into RetProbeContext. Now, only kprobe (which uses ProbeContext) can access args, and kretprobe (which uses RetProbeContext) can access ret.
