+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())
+  * 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.
+
+-------------------------------------------------------------------
+Wed Oct 30 15:29:42 UTC 2024 - Fredrik Lönnegren <fredrik.lonnegren@suse.com>
+
+- 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
+
+-------------------------------------------------------------------
+Wed Sep  4 08:44:47 UTC 2024 - Fredrik Lönnegren <fredrik.lonnegren@suse.com>
+

+
+- 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
+
+-------------------------------------------------------------------
+Tue May 21 07:07:12 UTC 2024 - Shung-Hsi Yu <shung-hsi.yu@suse.com>
+
+- Fix null pointer dereference in bpf_object__collect_prog_relos()
+  (bsc#1221101)
+  * Add libbpf-Fix-NULL-pointer-dereference-in-bpf_object__c.patch
+
+-------------------------------------------------------------------
+Sat May 11 07:03:51 UTC 2024 - Fredrik Lönnegren <fredrik.lonnegren@suse.com>
+
+- update to 1.4.2:
+  * Another struct_ops-focused bug fix release. It addresses a few more corner
+    cases when dealing with SEC("struct_ops") programs.
+  * It also improves error messaging around common use case of declaring
+    struct_ops BPF program and not referencing it from SEC(".struct_ops")
+    variable (backed by struct_ops BPF map).
+  * This release should improve overall experience of using BPF struct_ops
+    functionality.
+
+-------------------------------------------------------------------
+Thu May  2 08:19:03 UTC 2024 - Fredrik Lönnegren <fredrik.lonnegren@suse.com>
+
+- update to 1.4.1:
+  * Bug fix release fixing logic around determining whether to autoload
+    SEC("struct_ops") programs in cases when old kernel doesn't support some
+    optional callbacks and user reset them to NULL from BPF skeleton.
+
+-------------------------------------------------------------------
+Wed Apr  3 10:50:11 UTC 2024 - Shung-Hsi Yu <shung-hsi.yu@suse.com>
+

+  * support for BPF token throughout low-level and high-level APIs
+    (see also LIBBPF_BPF_TOKEN_PATH envvar)
+  * struct_ops functionality around handling multi-kernel
+    compatibility using BPF CO-RE principles and approaches
+  * BPF arena map support
+  * support __arena tagged global variables, which are automatically
+    put into BPF arena map
+  * BPF cookie support for raw tracepoint BPF programs in attach APIs
+    loaded or created, respectively
+  * add SEC("sk_skb/verdict") support
+  * support global subprog argument tagging for for kprobe/uprobe,
+    and perf_event BPF program with newly added __arg_ctx,
+    __arg_nonnull, __arg_nullable, __arg_trusted, and __arg_arena
+    annotations
+  * add bpf_core_cast() macro, improving ergonomics of
+    bpf_rdonly_cast() BPF helper
+  * __long() macro added for specifying 64-bit values when declaring
+    BTF-defined maps
+  * better GCC-BPF support in BPF CO-RE macros in bpf_core_read.h header
+  * show specific error messages when attempting to
+    use struct bpf_program/bpf_map instances there were not loaded or
+    created
+  * fix inner map's max_entries setting logic
+  * btf_ext__raw_data() and btf__new_split() APIs are added back
+  * ignore DWARF sections in BPF linker sanity checks, improving
+    handling of some corner cases
+  * fix potential NULL dereference when handling corrupted ELF files.
