OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/libbpf?expand=0&rev=23
- Update to release 0.8.0
* New features and APIs:
- support auto-resolution of binaries and shared libraries from PATH, if necessary;
- support attaching by function names (only by IP was supported before);
- support attaching to USDTs (SEC("usdt/...") and
bpf_program__attach_usdt()) with initially supported architectures:
x86-64 (amd64); x86 (i386); s390x; ARM64 (aarch64); RISC V (riscv);
- improved BPF verifier log reporting for CO-RE relocation failures (no
more obscure "invalid func unknown#195896080" errors);
- auto-adjust BPF ringbuf size according to host kernel's page size requirements;
- high-level BPF map APIs: bpf_map__lookup_elem(), bpf_map__update_elem(),
etc that validate key/value buffer sizes;
- bpf_link_create() can create all bpf_link-based (including raw_tp,
fentry/fexit, etc), falling back to bpf_raw_tracepoint_open() on old
kernels transparently;
- support opting out from auto-loading BPF programs declaratively with
SEC("?...");
- support opting out from auto-creation of declarative BPF maps with
bpf_map__set_autocreate();
- support multi-kprobes (SEC("kprobe.multi/...") and
bpf_program__attach_kprobe_multi_opts());
- support target-less SEC() programs (e.g., SEC("kprobe"), SEC("tp"), etc);
- support BPF sub-skeletons for "incomplete" BPF object files (requires
matching bpftool to generate .subskel.h);
- BPF cookie support for fentry/fexit/fmod_ret BPF programs
(bpf_program__attach_trace_opts());
- support for custom SEC() handlers (libbpf_register_prog_handler()).
* BPF-side API
- BPF-side USDT APIs. See new usdt.bpf.h header:
* BPF_USDT() program wrapper macro; bpf_usdt_arg(), bpf_usdt_arg_cnt(),
* bpf_usdt_cookie() helpers;
- new bpf_core_field_offset() CO-RE helper and support
bpf_core_field_size(type, field) forms;
- barrier() and barrier_var() macros for improving BPF code generation;
- __kptr and __kptr_ref tags added;
- ARC architecture support in bpf_tracing.h header;
- new BPF helpers:
* bpf_skb_set_tstamp();
* bpf_ima_file_hash();
