libeu is a static library with internal helper functions normally
included in all shared libraries. But when linking static (with
--enable-gcov) we need to explicitly link it into the test binaries.

       * tests/Makefile.am (libelf): Add $(libeu) when BUILD_STATIC.

Prevent binaries in src from colliding with libc++ headers

Discovered with Nix and LLVM 17. Headers inside of libc++ can easily
collide with binaries being linked in src. This results in clang trying
to include a binary as a header.

Fix this by removing '-I.' and '-I$(srcdir)' from AM_CPPFLAGS and
DEFAULT_INCLUDES in src/Makefile.am.

To facilitate this config/eu.am has been refactored. New file
config/eu-common.am contains all of the old eu.am but with the
AM_CPPFLAGS definition removed. eu.am now includes eu-common.am and
contains the old AM_CPPFLAGS definition.

eu.am functionality does not change, but src/Makefile.am can instead
include eu-common.am and define its own AM_CPPFLAGS without causing a
"multiply defined" warning during autoreconf.

debuginfod: populate _r_seekable on request

Since the schema change adding _r_seekable was done in a backward
compatible way, seekable archives that were previously scanned will not
be in _r_seekable. Whenever an archive is going to be extracted to
satisfy a request, check if it is seekable. If so, populate _r_seekable
while extracting it so that future requests use the optimized path.

The next time that BUILDIDS is bumped, all archives will be checked at
scan time. At that point, checking again will be unnecessary and this
commit (including the test case modification) can be reverted.

PR29472: debuginfod: add metadata query webapi, C api, client

This patch extends the debuginfod API with a "metadata query"
operation. It allows clients to request an enumeration of file names
known to debuginfod servers, returning a JSON response including the
matching buildids. This lets clients later download debuginfo for a
range of versions of the same named binaries, in case they need to to
prospective work (like systemtap-based live-patching). It also lets
server operators implement prefetch triggering operations for popular
but slow debuginfo slivers like kernel vdso.debug files on fedora.

Implementation requires a modern enough json-c library, namely 0.11,
which dates from 2014. Without that, debuginfod client/server bits
will refuse to build.

% debuginfod-find metadata file /bin/ls
% debuginfod-find metadata glob "/usr/local/bin/c*"

Refactored several functions in debuginfod-client.c, because the
metadata search logic is different for multiple servers (merge all
responses instead of first responder wins).

Documentation and testing are included.

debuginfod: PR28204 - RPM IMA per-file signature verification

Recent versions of Fedora/RHEL include per-file cryptographic
signatures in RPMs, not just an overall RPM signature. This work
extends debuginfod client & server to extract, transfer, and verify
those signatures. These allow clients to assure users that the
downloaded files have not been corrupted since their original
packaging. Downloads that fail the test are rejected.

Clients may select a desired level of enforcement for sets of URLs in
the DEBUGINFOD_URLS by inserting special markers ahead of them:

ima:ignore pay no attention to absence or presence of signatures
ima:enforcing require every file to be correctly signed

The default is ima:ignore mode. In ima:enforcing mode, section
queries are forced to be entire-file downloads, as it is not
possible to crypto-verify just sections.

IMA signatures are verified against a set of signing certificates.
These are normally published by distributions. The environment
variable $DEBUGINFOD_IMA_CERT_PATH contains a colon-separated path for
finding DER or PEM formatted certificates / public keys. These
certificates are assumed trusted. The profile.d scripts transcribe
/etc/debuginfod/*.certdir files into that variable.

As for implementation:

* configure.ac: Add --enable-default-ima-cert-path=PATH parameter.
  Check for libimaevm (using headers only).

* config/Makefile.am: Install defaults into /etc files.
* config/profile.{csh,sh}.in: Process defaults into env variables.
* config/elfutils.spec.in: Add more buildrequires.

* debuginfod/debuginfod.cxx (handle_buildid_r_match): Added extraction of the
  per-file IMA signature for the queried file and store in http header.
  (find_globbed_koji_filepath): New function.
  (parse_opt): New flag --koji-sigcache.
* debuginfod/debuginfod-client.c (debuginfod_query_server): Added policy for
  validating IMA signatures
  (debuginfod_validate_imasig): New function, with friends.

Support note NT_FILE for locating files.

Martin Milata:
------------------------------------------------------------------------------
RFE: dwfl_core_file_report: use NT_FILE core note if the link_map chain is broken
https://bugzilla.redhat.com/show_bug.cgi?id=1129777

The dwfl_core_file_report function follows dynamic linker's link_map chain in
order to determine the shared libraries used by the executable. As this data
structure is located in writable memory it can be overwritten by garbage, which
is sometimes the case.
 https://github.com/abrt/satyr/issues/127#issuecomment-46957546

Since version 3.7 (commit 2aa362c49), Linux kernel adds NT_FILE note to core
files which contains the files mapped by the process, including shared
libraries.
------------------------------------------------------------------------------

dwfl_core_file_report now tries to fall back on NT_FILE if the link_map chain
is broken.

elfutils would already find the appropriate binary file from
/usr/lib/debug/.build-id/ symbolic links. But those symbolic links do not have
to be present on the system while NT_FILE still points to the correct binaries.

Filenames from the note NT_FILE are used only if link_map filenames failed to
locate matching binaries.

tests/test-core.core.bz2 had to have its NT_FILE disabled as run-unstrip-n.sh
otherwise FAILs:
FAIL: 0x7f67f2aaf000+0x202000 - . - /home/jkratoch/redhat/elfutils-libregr/test-core-lib.so
PASS: 0x7f67f2aaf000+0x202000 - . - test-core-lib.so
As test-core-lib.so is found in link_map but it is not present on the disk
elfutils now chooses the more reliable filename from NT_FILE (although that
filename is also not found on the disk). Updating the expected text would be
also sufficient.
