Wed Oct 30 15:59:44 UTC 2024 - Fredrik Lönnegren <fredrik.lonnegren@suse.com>
|
|
|
|
- update to 1.5.0:
|
|
* libbpf can now open (but not load!) BPF objects of non-native endianness,
|
|
enabling cross-architecture support for BPF skeleton generation and BPF
|
|
object introspection
|
|
* BPF skeleton will now auto-attach SEC(".struct_ops") maps as part of
|
|
<skeleton>__attach() call
|
|
* BPF kprobe session programs support (SEC("kprobe.session"))
|
|
* allow specifying kernel module name for fentry/fexit BPF programs
|
|
(SEC(fentry/module:function)
|
|
* libbpf recognizes LIBBPF_LOG_LEVEL environment variable, which can be used
|
|
to set default log verboseness
|
|
* BPF ringbuf APIs that limit maximum number of consumed records at a time
|
|
(ring_buffer__consume_n(), ring__consume_n())
|
|
* distilled BTF support (btf__distill_base(), btf__relocate())
|
|
* BPF link-based attachment of BPF_PROG_TYPE_SOCKMAP programs
|
|
(bpf_program__attach_sockmap())
|
|

|
|
* fixes for fetching syscall arguments on arm64, s390x, risc-v architectures
|
|

|
|
* __bpf_fastcall support for a few BPF helpers

|
|
bpf_object__open() APIs and BPF subskeletons
|
|
* BPF skeleton backwards compatibility handling fixes
|
|
* handle LTO-produced *.llvm.<hash> symbols better
|
|
* feature detection fixes in the presence of BPF token inside user namespace

* older kernels have broken PID filtering logic for multi-uprobes, libbpf now
|
|
detects this and avoids the use of multi-uprobes for USDTs
|
|
* fix accidental drop of FD_CLOEXEC flag during BPF map reuse
|
|

|
|
- 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();
|
|
* bpf_kptr_xchg();
|
|
* bpf_map_lookup_percpu_elem().
|
|
* Bug fixes
|
|
- netlink bug fixes;
|
|
- libbpf.pc fixes to support patch releases properly;
|
|
- BPF_MAP_TYPE_PERF_EVENT_ARRAY map auto-pinning fix;
|
|
- minor CO-RE fixes and improvements for some corner cases;
|
|
- various other small fixes and improvements.

|
|
- btf_dump__dump_type_data() API, allowing to dump binary data according to BTF type description;

|
|
- bpf_map__initial_value() API to get initial value of mmap-ed BPF maps;

|
|
- support for weak typed __ksym externs;
|
|
- BPF timer helpers: bpf_timer_init(), bpf_timer_set_callback(), bpf_timer_start(), bpf_timer_cancel();
|
|

|
|
- pass NLM_F_EXCL when creating TC qdisc;
