- Update to 0.5.0:
+ New features and user-space APIs:
- libbpf_set_strict_mode() allowing to opt-in into backwards incompatible libbpf-1.0 changes. See "Libbpf: the road to 1.0" and "Libbpf 1.0 migration guide" for more details.
- streamlined error reporting for low-level APIs, high-level error-returning APIs, and pointer-returning APIs (as a libbpf-1.0 opt-in);
- "Light" BPF skeleton support;
- BPF_PROG_TYPE_SYSCALL support;
- BPF perf link support for kprobe, uprobe, tracepoint, and perf_event BPF programs;
- BPF cookie support for kprobe, uprobe, tracepoint, and perf_event BPF programs through bpf_program__attach_[ku]probe_opts() APIs;
- allow to specify ref_ctr_off for USDT semaphores through bpf_program__attach_uprobe_opts() API;
- btf_custom_path support in bpf_object_open_opts, allowing to specify custom BTF for CO-RE relocations;
- sk_reuseport/migrate program type support;
- btf_dump__dump_type_data() API, allowing to dump binary data according to BTF type description;
- btf__load_into_kernel() and btf__load_from_kernel_by_id(), and split BTF variants of them;
- btf__load_vmlinux_btf() and btf__load_module_btf() APIs;
- bpf_map__initial_value() API to get initial value of mmap-ed BPF maps;
- bpf_map_lookup_and_delete_elem_flags() API.
+ BPF-side APIs and features:
- support for weak typed __ksym externs;
- BPF timer helpers: bpf_timer_init(), bpf_timer_set_callback(), bpf_timer_start(), bpf_timer_cancel();
- bpf_get_attach_cookie() helper to get BPF cookie from BPF program side;
- bpf_get_func_ip() helper;
- bpf_sys_bpf() helper;
- bpf_task_pt_regs() helper;
- bpf_btf_find_by_name_kind() helper;
- usability improvements for bpf_tracing.h when target architecture is missing.
+ Bug fixes and compatibility improvements:
- improve BPF support detection on old Red Hat kernels with backported BPF patches;
- improvements for LTO builds with GCC 10+;
- pass NLM_F_EXCL when creating TC qdisc;
- better support of BPF map reuse on old kernels;
- fix the bug resulting in sometimes closing FD 0, which wasn't created and owned by libbpf itself.
