* Mon Sep 27 2021 shung-hsi.yu@suse.com
- 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.
- Remove patches merged upstream

(bsc#1188419 jsc#SLE-17288 jsc#SLE-18805).
- Fix LIBSUBDIR
+ libdir.patch
* Mon Jun 08 2020 mrostecki@suse.com

consistency with bpftool package.
* Tue Jan 07 2020 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; anymore
- raw_tp/tp and uprobe/uretprobe section prefixes added
- new bpf_program__get_{type,expected_attach_type} getters
- preserve error code on program load failure
+ Fixes
- btf_dump padding handling
- bpf_object__name() returning name, not path
- ELF section handling off-by-one bug fix
- mem leak/double free fix in BPF program relocation code
