libbpf-1.6.1-160000.1.2

- update to 1.6.0:
  * add more control over BPF object lifetime with new preparation step
    (bpf_object__prepare() API)
  * libbpf will report symbolic error code (e.g., "-EINVAL") in addition to
    human-readable error description
  * bpf_prog_stream_read() API
  * BPF token support when attaching BPF trampoline-based BPF programs in
    bpf_program__set_attach_target()
  * BPF token support for BPF_BTF_GET_FD_BY_ID command
  * support multi-uprobe session (SEC("uprobe.session")) BPF programs
  * support unique_match option for multi-kprobe attachment
  * support creating and destroying qdisk with BPF_TC_QDISC flag;
  * bpf_program__attach_cgroup_opts() which enables more precise cgroup-based
    attachment ordering
  * automatically take advantage of memory-mappable kernel BTF
    (/sys/kernel/btf/vmlinux), if supported
  * emit_strings option for BTF dumper API, improving string-like data printing
  * add BPF program's func and line info accessors
  * BPF linker supports linking ELF object files coming from memory buffer and
    referenced by FD, in addition to file path-based APIs;
  * small improvements to BTF dedup to handle rare quirky corner cases produces
    by some compilers
  * add likely() and unlikely() convenience macros;
  * __arg_untrusted annotation for BPF global subprog arguments;
  * bpf_stream_printk() macro for working with BPF streams;
  * bpf_usdt_arg_size() API
- update to 1.6.0:
  * fixing a possible crash when handling BPF arena global variable relocations
- drop 0001-libbpf-Add-identical-pointer-detection-to-btf_dedup_.patch, which
  is now included

- Workaround kernel module size increase due to BTF deduplication
  issue since the introduction of TYPEOF_UNQUAL (poo#183503 bsc#1244135)
  * add 0001-libbpf-Add-identical-pointer-detection-to-btf_dedup_.patch

- update to 1.5.1:
  * Patch release with a single backported change that improves compatibility
    story of older versions of libbpf-cargo.

    453601a65a6ebcf523b009585b49ce0ad0adeff1

- Drop libbpf-Fix-NULL-pointer-dereference-in-bpf_object__c.patch
  * included since 1.4.0

- 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())
  * bpf_object__token_fd() API to fetch BPF token FD of a BPF object, if any
  * fixes for fetching syscall arguments on arm64, s390x, risc-v architectures
  * better GCC-BPF source code compatibility
  * __bpf_fastcall support for a few BPF helpers
  * __uptr annotation definition added to bpf/bpf_helpers.h API header
  * fixes and improvements around handling missing and nulled out struct_ops
    programs
  * fixed mmap()-ing logic for global data, fixing interop between generic
    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
  * few BTF dumper formatting fixes
  * a few more small fixes all around.

- update to 1.4.7:
  * fix interop issues between generic bpf_object__open() APIs and BPF
    subskeleton w.r.t. global data handling
  * speed up BTF sanity checks by skipping already validated base BTF
  * fix legacy treatment of non-SEC()-annotated subprogram as entry BPF program
    in some cases

- update to 1.4.6:
  * BPF skeleton forward compatibility fix (f6f2402);
  * BTF endianness inheritance bug fix (fe28fae).

- update to 1.4.5:
  * Another small bug fix release backporting https://github.com/
    libbpf/libbpf/commit/d9f9fd5b22223ae69c62e083da6093d95a0db799
    which works around kernel-side bug with USDT PID filtering on
    kernels that support multi-uprobe (but have broken PID
    filtering).

- update to 1.4.3:
  * Fix libbpf unintentionally dropping FD_CLOEXEC flag when (internally)
    duping FDs

- Fix null pointer dereference in bpf_object__collect_prog_relos()
  (bsc#1221101)
  * Add libbpf-Fix-NULL-pointer-dereference-in-bpf_object__c.patch
