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. - Remove patches merged upstream + libdir.patch + libbpf-Fix-build-with-latest-gcc-binutils-with-LTO.patch ------------------------------------------------------------------- Fri Aug 27 06:20:53 UTC 2021 - Michal Suchanek <msuchanek@suse.com> - Fix LTO build (bsc#1188749). + libbpf-Fix-build-with-latest-gcc-binutils-with-LTO.patch ------------------------------------------------------------------- Fri Aug 20 08:47:47 UTC 2021 - Michal Suchanek <msuchanek@suse.com> - Depend on new enough Linux headers. ------------------------------------------------------------------- Mon Aug 2 11:00:28 UTC 2021 - Callum Farmer <gmbr3@opensuse.org> - Create libbpf0-32bit needed by libdwarves1-32bit ------------------------------------------------------------------- Sat Jul 17 15:38:52 UTC 2021 - Michal Suchanek <msuchanek@suse.com> - libbpf is now a separate project, stop building from the kernel (bsc#1188419 jsc#SLE-17288 jsc#SLE-18805). - Fix LIBSUBDIR + libdir.patch ------------------------------------------------------------------- Mon Jun 8 23:52:39 UTC 2020 - Michał Rostecki <mrostecki@suse.com> - Add python3 as a build dependency. ------------------------------------------------------------------- Sun Feb 2 19:50:55 UTC 2020 - Michał Rostecki <mrostecki@opensuse.org> - Build libbpf from kernel sources, not from github sources, for consistency with bpftool package. ------------------------------------------------------------------- Tue Jan 7 14:36:44 UTC 2020 - Tomáš Chvátal <tchvatal@suse.com> - Reflect SUSE CFLAGS - Do not bother with obscpio if we are fetching direct releases - Remove patch 0001-makefile-Fix-install-target.patch seems to build/install without it just fine - Update to 0.0.6: + New features - new extensible bpf_object__open_{file,mem} APIs and DECLARE_LIBBPF_OPTS() macro to go with them - bpf_helpers.h, bpf_endian.h, and bpf_tracing.h are now distributed with libbpf - BPF CO-RE: added field size, field existence, and bitfield relocation support - BPF CO-RE: BPF_CORE_READ(), bpf_core_field_exists(), bpf_core_field_size() and other BPF CO-RE related helpers available through bpf_core_read.h header - bpf_object__open() API now auto-detects program type from its section name - BPF_PROG_TRACING programs support (incuding BTF-typed raw tracepoints, fentry/fexit programs) - mmap() support for BPF global variables - declarative map pinning support added - probe_read_{user,kernel}[_str]() BPF helpers added - bpf_get_link_xdp_info() function to get more XDP information added - a bunch of other AF_XDP changes + Usability improvements - no need for int version SEC('version') = 1;
