commit d7193bd7c9dc2a979352eee7fc446dacd3e97779
Author: Mark Wielaard <mark@klomp.org>
Date: Sun May 12 00:37:45 2019 +0200
libelf: Mark shdr_flags dirty if offset or size changes during update.
We forgot to mark the shdr_flags dirty when only the sh_size or
sh_offset changed during elf_update (). This meant that if there were
no other shdr changes we only wrote out the section data, but didn't
write out the shdr table to the file.
Add a testcase that puts some sections in the reverse order and then
writes out the resulting file again without doing any other
updates. This would show the issue after write out of the
(re-reversed) ELF file (the .shstrtab section offset would be wrong
causing all section names to be garbage). Also run a self test.

commit 28b5f578ae772bb2404c3847e4e22ad1c407af54
Author: Mark Wielaard <mark@klomp.org>
Date: Tue Apr 30 13:00:17 2019 +0200
libelf: If xlate can only convert the ELF note header, just do that.
When we started parsing new style ELF_T_NHDR8 notes we added extra
checks on alignment and padding. When those failed we would stop
converting and just return the rest of the ELF Note unconverted.
In the case were we just had enough data for just the ELF Note header
and the destionation and source weren't the same we would then
accidentially throw away the Note header conversion we just did.
Fix that by indicating we did correctly convert just the header.
Adds testcase that compares parsing ELF notes with gelf_getnote
and parsing the raw data by hand using elf32_xlatetom using just
the Note header and ignoring the (raw) note data.

%changelog
* Tue Nov 26 2019 Mark Wielaard <mjw@fedoraproject.org> - 0.178-1
- New upstream release.
- debuginfod: New server, client tool and library to index and fetch
ELF/DWARF files addressed by build-id through HTTP.
- doc: There are now some manual pages for functions and tools.
- backends: The libebl libraries are no longer dynamically loaded
through dlopen, but are now compiled into libdw.so directly.
- readelf: -n, --notes now takes an optional "SECTION" argument.
-p and -x now also handle section numbers.
New option --dyn-sym to show just the dynamic symbol table.
- libcpu: Add RISC-V disassembler.
- libdw: Abbrevs and DIEs can now be read concurrently by multiple
threads through the same Dwarf handle.
- libdwfl: Will try to use debuginfod when installed as fallback to
retrieve ELF and DWARF debug data files by build-id.
* Wed Aug 14 2019 Mark Wielaard <mjw@fedoraproject.org> - 0.177-1
- New upstream release.
- elfclassify: New tool to analyze ELF objects.
