dwarves (1.25-0.1) unstable; urgency=medium

  * Non-maintainer upload.
  * New upstream release.
    Changes since 1.24:

    DWARF loader:

    - Support for DW_TAG_unspecified_type more generally, that in binutils
      2.40 is used for assembly functions, resulting in BTF encoding problems
      when building the Linux kernel.

    - Make sure struct member offsets are in ascending order. This is part of
      the set of changes to support encoding BTF for Rust for use with the
      Linux kernel, where the BTF verifier considers invalid offset unordered
      struct members.

    - Support C atomic types (DW_TAG_atomic_type), that are not used in the
      Linux kernel but is present in user space components such as Open
      VSwitch.

    BTF loader:

    - Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, to
      encode things like __rcu, __user annotations in the Linux kernel. This
      is still in flux with changes in how these are encoded that resulted
      from the discussion to support this in gcc in addition to in clang,
      where it was first designed.

    BTF encoder:

    - Exclude functions with the same name (static functions in different
      CUs), inconsistent prototypes or not following calling convention.

    - Allow generation of BTF for optimized functions, those that end with a
      .isra* suffix (inter procedural scalar replacement of aggregates) or
      .constprop* (constant propagation).

    Pretty printer:

    - For now the DW_TAG_LLVM_annotation tags are being suppressed, so the
      output from BTF and DWARF matches, further work is planned to support it
      so that the output matches the original source code and can be
      recompilable, resulting in the same DWARF info.

    - Support C atomic types, allowing the generation of source code that can
      be compiled with resulting DWARF info matching the original source code.

    pahole:

    - Support --lang=/--lang_exclude=asm, the DW_LANG_ define for assembly is
      out of order, special case it to support asking for CUs written in
      assembly to be selected or excluded.

    - Support suppressing the atomic type modifiers/attributes.

    - Allow filtering out functions optimized by the compiler, where the
      calling convention isn't the one expected by BPF or arguments are
      optimized out.

    - Support --compile from DWARF in addition to from BTF, this allows user
      space components such as Open VSwitch to use pahole to generate
      compilable code for its data structures.

    btfdiff:

    - Exclude RUST CUs, as those are not yet being BTF encoded.

dwarves (1.24-1) experimental; urgency=medium

  * New upstream release. Closes: 1018906.
    Changes since 1.23:

    BTF encoder:

    - Add support to BTF_KIND_ENUM64 to represent enumeration entries
      with more than 32 bits.

    - Support multithreaded encoding, in addition to DWARF
      multithreaded loading, speeding up the process.

      Selected just like DWARF multithreaded loading, using the
      'pahole -j' option.

    - Encode 'char' type as signed.

    BTF Loader:

    - Add support to BTF_KIND_ENUM64.

    pahole:

    - Introduce --lang and --lang_exclude to specify the language the
      DWARF compile units were originated from to use or filter.

      Use case is to exclude Rust compile units while aspects of the
      DWARF generated for it get sorted out in a way that the kernel
      BPF verifier don't refuse loading the BTF generated from them.

    - Introduce --compile to generate compilable code in a similar
      fashion to

       bpftool btf dump file vmlinux format c > vmlinux.h

      As with 'bpftool', this will notice type shadowing, i.e. multiple
      types with the same name and will disambiguate by adding a suffix.

    - Don't segfault when processing bogus files.

  * Update libbpf-dev and linux-libc-dev build depends.

    needed for #744847.

dwarves (1.23-1) experimental; urgency=medium

  * New upstream release.
    Changes since 1.22:

    DWARF loader:

    - Read DW_TAG_LLVM_annotation tags, associating it with variables,
      functions, types. So far this is only being used by the BTF
      encoder, but the pretty printer should use this as well in a
      future release, printing these attributes when available.

    - Initial support for DW_TAG_skeleton_unit, so far just suggest
      looking up a matching .dwo file to be used instead. Automagically
      doing this is in the plans for a future release.

    - Fix heap overflow when accessing variable specification.

    BTF encoder:

    - Support the new BTF type tag attribute, encoding
      DW_TAG_LLVM_annotation DWARF tags as BTF_KIND_TYPE_TAG and
      BTF_KIND_DECL_TAG.

      This allows __attribute__((btf_type_tag("tag1"))) to be used for
      variables, functions, typedefs, so that contextual information can
      be stored in BTF and used by the kernel BPF verifier for more checks.

      The --skip_encoding_btf_type_tag option can be used to suppress this.

    - Fix handling of percpu symbols on s390.

    BTF loader:

    - Use cacheline size to infer alignment.

    btfdiff:

    - Now that the BTF loader infers struct member alingment, and as that
      is just an heuristic, suppress printing the alignment when pretty
      printing from BTF info like is done when printing from DWARF.

    pahole:

    - Add --skip_missing so that we don't stop when not finding one of
      the types passed to -C.

    Pretty printer:

    - Fix __attribute__((__aligned__(N)) printing alignment for struct
      members.

    - Fix nested __attribute__(__aligned__(N)) struct printing order,
      so that rebuilding from the printed source circles back to the
      original source code alignment semantics.

    Build:

    - No need to download libbpf source when using the system library
      (libbpf-devel).

    - Make python optional

  * Drop pahole-manpage-fixes.patch, merged upstream.
  * Bump build-depends libbpf-dev version to 1:0.7~.

dwarves (1.22-1) unstable; urgency=low

  * New upstream release.
    Changes since 1.20:

    pahole:
    - Allow encoding BTF to a separate BTF file (detached) instead of to a new
      ".BTF" ELF section in the file being encoded (vmlinux usually).
    - Introduce -j/--jobs option to specify the number of threads to
      use. Without arguments means one thread per CPU. So far used for
      the DWARF loader, will be used as well for the BTF encoder.
    - Show all different types with the same name, not just the first one found.
    - Introduce sorted type output (--sort), needed with multithreaded
      DWARF loading, to use with things like 'btfdiff' that expects
      the output from DWARF and BTF types to be comparable using 'diff'.
    - Stop assuming that reading from stdin means pretty printing as this broke
      pre-existing scripts, introduce a explicit --prettify command line option.
    - Improve type resolution for the --header command line option.
    - Disable incomplete CTF encoder, this needs to be done using the external
      libctf library.
    - Do not consider the ftrace filter when encoding BTF for kernel functions.
    - Add --kabi_prefix to avoid deduplication woes when using
      _RH_KABI_REPLACE()
    - Add --with_flexible_array to show just types with flexible arrays.

    DWARF Loader:
    - Multithreaded loading, requires elfutils >= 0.178.
    - Lock calls to non-thread safe elfutils' libdw functions (dwarf_decl_file()
      and dwarf_decl_line())
    - Change hash table size to one that performs better with current typical
      vmlinux files.
    - Allow tweaking the hash table size from the command line.
    - Stop allocating memory for strings obtained from libdw, just defer freeing
      the Dwfl handler so that references to its strings can be safely kept.
    - Use a frontend cache for the latest lookup result.
    - Allow ignoring some DWARF tags when loading for encoding
      BTF, as BTF doesn't have equivalents for things like
      DW_TAG_inline_expansion and DW_TAG_label.
    - Allow ignoring some DWARF tag attributes, such as DW_AT_alignment,
      not used when encoding BTF.
    - Do not query for non-C attributes when loading a C language CU
      (compilation unit).

    BTF encoder:
    - Preparatory work for multithreaded encoding, the focus for 1.23.

    btfdiff:
    - Support diffing against a detached BTF file,
      e.g.: 'btfdiff vmlinux vmlinux.btf'
    - Support multithreaded DWARF loading, using the new pahole --sort
      option to have the output from both BTF and DWARF sorted and thus
      comparable via 'diff'.

    Build:
    - Support building with libc libraries lacking either obstacks or argp, such
      as Alpine Linux's musl libc.
    - Support systems without getconf() to obtain the data cacheline size, such
      as musl libc.
    - Add a buildcmd.sh for test builds, tested using the same set of containers
      used for testing the Linux kernel perf tools.
    - Enable selecting building with a shared libdwarves library or statically.
    - Allow one to use the libbpf package found in distributions instead
      of with the accompanying libbpf git submodule.

    Cleanups:
    - Address lots of compiler warnings accumulated by not using -Wextra, it'll
      be added in the next release after allowing not to use it to build libbpf.
    - Address covscan report issues.

    Documentation:
    - Improve the --nr_methods/-m pahole man page entry.
    - Clarify that currently --nr_methods doesn't work together witn -C.

  * Refresh patches.

dwarves-dfsg (1.20-2) unstable; urgency=high

  * Build-Depends on libbpf-dev on Linux builds only.

dwarves-dfsg (1.20-1) unstable; urgency=medium

  * New upstream release.
    Changes since 1.19:

    BTF encoder:
      - Improve ELF error reporting using elf_errmsg(elf_errno()).
      - Improve objcopy error handling.
      - Fix handling of 'restrict' qualifier, that was being treated
        as a 'const'.
      - Support SHN_XINDEX in st_shndx symbol indexes, to handle ELF
        objects with more than 65534 sections, for instance, which
        happens with kernels built with 'KCFLAGS="-ffunction-sections
        -fdata-sections", Other cases may include when using FG-ASLR, LTO.
      - Cope with functions without a name, as seen sometimes when
        building kernel images with some versions of clang, when a
        SEGFAULT was taking place.
      - Fix BTF variable generation for kernel modules, not skipping
        variables at offset zero.
      - Fix address size to match what is in the ELF file being
        processed, to fix using a 64-bit pahole binary to generate BTF
        for a 32-bit vmlinux image.
      - Use kernel module ftrace addresses when finding which functions
        to encode, which increases the number of functions encoded.
    DWARF loader:
      - Support DW_AT_data_bit_offset
      - DW_FORM_implicit_const in attr_numeric() and attr_offset()
      - Support DW_TAG_GNU_call_site, its the standardized rename of
        the previously supported DW_TAG_GNU_call_site.
    build:
        - Fix compilation on 32-bit architectures.

  * Refresh patches.
  * Remove ctfdwdiff and README.cross so to reuse upstream tarball as-is.
  * Update Standards-Version to 4.5.1
  * Update debhelper compatibility to 13:
    - install missing binaries: btfdiff and fullcircle
  * Add upstream metadata file
  * gbp: set upstream tarball compression to xz
  * Add lintian override for orig-tarball-missing-upstream-signature,
    see #882694.

dwarves-dfsg (1.19-1) unstable; urgency=high

  * New upstream release. Closes: #978691.
    Changes since 1.18:
    - Support split BTF, where a main BTF file, vmlinux, can be used
      to find types and then a kernel module, for instance, can have
      just what is unique to it
    - Update libbpf to get the split BTF support and use some of its
      functions to load BTF and speed up DWARF loading and BTF encoding
    - Support cross-compiled ELF binaries with different endianness
    - Support showing typedefs for anonymous types, like structs,
      unions and enums
    - Align enumerators
    - Workaround bugs in the generation of DWARF records for functions in
      some gcc versions that were causing breakage in the encoding of BTF
    - Ignore zero-sized ELF symbols instead of erroring out
    - Handle union forward declaration properly in the BTF loader
    - Introduce --numeric_version for use in scripts and Makefiles
    - Try sole pfunct argument as a function name, just like pahole
      with type names
    - Speed up pfunct using some of the load techniques used in pahole
    - Discard CUs after BTF encoding as they're not used anymore,
      greatly reducing memory usage and speeding up vmlinux BTF encoding
    - Revamp how per-CPU variables are encoded in BTF
    - Include BTF info for static functions
    - Use BTF's string APIs for strings management, greatly improving
      performance over the tsearch()
    - Increase size of DWARF lookup hash table, shaving off about 1
      second out of about 20 seconds total for Linux BTF dedup
    - Stop BTF encoding when errors are found in some DWARF CU
    - Implement --packed, to show just packed structures, for instance,
      here are the top 5 packed data structures in the Linux kernel
    - Fix bug in distros such as OpenSUSE:15.2 where DW_AT_alignment
      isn't defined

  * Refresh patches.

dwarves-dfsg (1.18-1) unstable; urgency=medium

  [ Domenico Andreoli ]
  * New upstream release (changes since 1.17):
    - Use type information to pretty print raw data from stdin, all
      documented in the man pages, further information in the csets.
    - Store percpu variables in vmlinux BTF. This can be disabled when
      debugging kernel features being developed to use it.
    - pahole now should be segfault free when handling gdb test suit
      DWARF files, including ADA, FORTRAN, rust and dwp compressed files,
      the later being just flatly refused, that got left for v1.19.
    - Bail out on partial units for now, avoiding segfaults and providing
      warning to user, hopefully will be addressed in v1.19.
      Closes: #977715.
  * Update Homepage link. Closes: #978708.
  * Drop debian/compat in favor of Build-Depends: debhelper-compat.
  * Fix typo in pahole manual page.
  * Fix escaping in pahole manual page.
  * Fix debian/copyright lintian errors.
  * Revert test to a superficial pahole --version until partial units
    become supported.

  [ Luca Boccassi ]
  * Use packaged libbpf instead of the statically linked. Closes: #979105.

dwarves-dfsg (1.17-1) unstable; urgency=low

  * New upstream release (changes since 1.16):

    BTF loader:
     - Support raw BTF as available in /sys/kernel/btf/vmlinux.

    pahole:
     - When the sole argument passed isn't a file, take it as a class name:
     - Do not require a class name to operate without a file name.
     - Make --find_pointers_to consider unions:
     - Make --contains and --find_pointers_to honour --unions
     - Add support for finding pointers to void:
     - Make --contains and --find_pointers_to to work with base types:
     - Make --contains look for more than just unions, structs:
     - Consider unions when looking for classes containing some class:
     - Introduce --unions to consider just unions:
     - Fix -m/--nr_methods - Number of functions operating on a type pointer

    man-pages:
     - Add section about --hex + -E to locate offsets deep into sub structs.
     - Add more information about BTF.
     - Add some examples.

  * Update to Standards-Version 4.5.0:
    - Drop get-orig-source rules target
    - Add Rules-Requires-Root: no
  * Update debhelper compat to 12.

dwarves-dfsg (1.15-1) unstable; urgency=medium

  [ Theodore Y. Ts'o ]
  * New upstream release (changes since 1.12, closes: #931142):
    - Add support for BTF encoding which is a much more compact way
      of encoding C type information.  It is derived from CTF (Compact
      C-Type format) and is designed for use with eBPF.
    - Add initial support for the DWARF DW_TAG_partial_unit
    - Improve support for pretty-printing unions
    - Teach pahole to show where a struct was used, via the -I option
    - Use the running kernel by default when no file name is passed
    - Improve man pages
    - Support new BTF deduplication algorithm found the Linux kernel's
      libbpf library, which allows type information for the kernel to
      be stored in roughly 1% of the space.
    - Add a new utility, btfdiff, which compares the pretty-printed
      type information between two kernel images.
    - Teach pahole to use the BTF information to pretty print structures
      using the BTF information using "pahole -F btf", which is much faster
      than using the Dwarf information.
    - Infer the __packed__ attribute for structures without alignment holes
      and which violate the natural types' alignment requirements.
    - Support DWARF5's DW_AT_alignment tag
    - Add a --compile option to pfunct which produces compileable
      output for function prototypes in an object file.
    - Miscellaneous bug fixes
