libbpf: Upgrade to 1.7.0 release

2026-03-31T02:46:38+00:00

User space-side features * bpf_map__set_exclusive_program() and bpf_map__exclusive_program() APIs for exclusive map creation; * bpf_program__assoc_struct_ops() and bpf_prog_assoc_struct_ops() APIs to associate a non-struct_ops BPF program with a struct_ops map; * btf__permute() API to rearrange BTF types in-place according to a provided mapping; * BTF type lookup optimization: binary search for btf__find_by_name() and btf__find_by_name_kind(); * btf__add_btf() now accepts split BTF sources; * fsession support (SEC("fsession+") / SEC("fsession.s+")); * BPF_F_CPU and BPF_F_ALL_CPUS flags support for per-CPU map operations; * arena globals are moved to the end of the arena mmap region if kernel supports it; * support for LLVM-generated indirect jump tables (BPF ISA v4) via .jumptables ELF section and BPF_MAP_TYPE_INSN_ARRAY maps; * avoid expensive kallsyms parsing when kprobe.session target is an exact function match; * new dont_enable option in struct bpf_perf_event_opts to suppress perf event auto-enablement; BPF-side features * USDT SIB (Scale-Index-Base) addressing support; * dynptr helper signatures (bpf_dynptr_from_mem, bpf_dynptr_read, bpf_dynptr_write, bpf_dynptr_data) widened from 32-bit to 64-bit size/offset parameters; Bug fixes * As usual, a number of bug fixes included, see full commit log for details.

meta-openembedded/all: adapt to UNPACKDIR changes

2025-06-25T13:44:52+00:00

Please see https://git.yoctoproject.org/poky/commit/?id=4dd321f8b83afecd962393101b2a6861275b5265 for what changes are needed, and sed commands that can be used to make them en masse. I've verified that bitbake -c patch world works with these, but did not run a world build; the majority of recipes shouldn't need further fixups, but if there are some that still fall out, they can be fixed in followups.
