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.

commit 4a90cb11140a6bb3712228861a32e4035013ad85

libdwfl: Find and handle compressed vmlinuz image.
Both the dwfl_linux_kernel_find_elf callback and the
dwfl_linux_kernel_report_offline reporting function only handled
vmlinix images possibly compressed with .gz, .bz2 or .xz extension.
They did not find or handle the much more common vmlinuz compressed
images.
It is not completely clear why we didn't up to now. Support for
compressed ELF files was added in 2009 and the code was updated to
to try to find the .gz, .bz2 or .xz extension variants in 2011.
But not the vmlinuz named variant.

debuginfod: Fix implicit conversion from 'CURLcode' to 'CURLMcode'
GCC10 warns when converting the value of one enum type into another:
debuginfod-client.c:530:24: error: implicit conversion from ‘CURLcode’
to ‘CURLMcode’ [-Werror=enum-conversion]
530 | curl_res = curl_easy_getinfo(target_handle,

libcurl has different error code enums. The "easy" interfaces return
a CURLcode error. The "multi" interface functions return a CURLMcode.

commit d8bad02afc7b7f30402b4e0e458df874a6d600da
Author: Mark Wielaard <mark@klomp.org>

debuginfod: Check the DEBUGINFOD_URLS environment variable early in client.
If the debuginfod-client isn't configured we should do as little
as possible. Simply return early with ENOSYS if no servers are
configured. This means we won't check
This does change the behavior of the debuginfod_find calls slightly.
Previously we would setup and check the cache if the given build-id
was valid. Which might have provided a result if an earlier client
had run with the same cache and valid server URLs which knew about
that particular build-id. Now we don't return any cached results
unless at least one server is configured.
This prevents selinux errors when the library is used in a confined
setup.

debuginfod: usability tweaks, incl. $DEBUGINFOD_PROGRESS client support
This facility allows a default progress-printing function to be
installed if the given environment variable is set. Some larger usage
experience (systemtap fetching kernels) indicates the default timeout
is too short, so forked it into a connection timeout (default short)
and a transfer timeout (default unlimited).

debuginfod: pass a distro-summary User-Agent request header
It may be useful for a debuginfod server operator to know what kinds
of clients make webapi requests. This is mainly as a
telemetry/diagnostic (though the data cannot be really trusted). It
may also be useful to automate downloading of distro packages to a
debuginfod server in the case of an unknown hex buildid. doc/testing
not affected as these are diagnostics.

libasm.h: Don't include libebl.h. Define an opaque Ebl handle.
Using libasm isn't really usable without a way to create an Ebl handle.
But we don't support libebl.h (and libebl itself). Just define the
Ebl handle as an opaque struct. Code that uses it needs to figure out
how to instantiate one itself (they cannot in any supportable way...)

%description debuginfod-client
The elfutils-debuginfod-client package contains shared libraries
dynamically loaded from -ldw, which use a debuginfod service
to look up debuginfo and associated data. Also includes a
command-line frontend.
%description debuginfod-client-devel
The elfutils-debuginfod-client-devel package contains the libraries
to create applications to use the debuginfod service.
%description debuginfod
The elfutils-debuginfod package contains the debuginfod binary
and control files for a service that can provide ELF/DWARF
files to remote clients, based on build-id identification.
The ELF/DWARF file searching functions in libdwfl can query
such servers to download those files on demand.

keep subpackages in sync.
* Tue Nov 26 2019 Mark Wielaard <mjw@redhat.com> - 0.178-2
- 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.
- Fix libdebuginfod file list for debuginfo-client[-devel].
* Fri Jul 5 2019 Mark Wielaard <mjw@redhat.com> - 0.176-5
