- update to 1.0.1:
* fix inadvertently changed struct bpf_object_open_opts memory layout;
* fix btf.h header relying on struct enum64 type defined in kernel UAPI headers;
* fix NULL pointer exception in API btf_dump__dump_type_data;
* remove struct btf_map_def accidentally left in bpf_helpers.h header.
* All deprecated APIs and features removed!
* support for syscall-specific kprobe/kretprobe
(SEC("ksyscall/") and SEC("kretsyscall/"));
* support for sleepable uprobe BPF programs (SEC("uprobe.s"));
* support for per-cgroup LSM BPF programs (SEC("lsm_cgroup"));
* support for new BPF CO-RE relocation TYPE_MATCHES;
* bpf_prog_load() and bpf_map_create() are now smarter about handling program
and map name on old kernels (it will be ignored if kernel doesn't support
names);
* BTF_KIND_ENUM64 support;
* increase tracing attachment (kprobe/uprobe/tracepoint) robustness by using
tracefs or debugfs, whichever is mounted;
* new APIs for converting BPF enums to their string representation:
* libbpf_bpf_prog_type_str();
* libbpf_bpf_map_type_str();
* libbpf_bpf_link_type_str();
* libbpf_bpf_attach_type_str();
* bpf_program__set_autoattach() and bpf_program__autoattach() to allow opting
out from auto-attaching of BPF program by BPF skeleton;
* perf_buffer__buffer() API to give access to underlying per-CPU buffer for BPF ringbuf;
* bpf_obj_get_opts() API for more flexible fetching of BPF kernel objects' information.
