Subject: [PATCH] Ensure ELF files get stripped when debuginfo is disabled
Depending on libmagic version, PIE executables can be reported as
"shared object" avoiding the strip. And so will any libraries because
we're explicitly skipping them for whatever historical reason - perhaps
because there's a separate script for stripping the libraries, but that
has been never enabled in rpm, and relying on "file" strings to do this
is hopelessly unreliable.
Also drop file permissions checks: making shared libraries executable
just to have them stripped is not sensical, especially in the light of
commit 80818e4f902ba3cf85e4cfcd8a7a4c71c601f3cf

Subject: [PATCH] Fix IMA signature lengths assumed constant (#1833,
RhBug:2018937)
At least ECDSA and RSA signatures can vary in length, but the IMA code
assumes constant lengths and thus may either place invalid signatures on
disk from either truncating or overshooting, and segfault if the stars are
just so.
Luckily the signatures are stored as strings so we can calculate the
actual lengths at runtime and ignore the stored constant length info.
Extend hex2bin() to optionally calculate the lengths and maximum,
and use these for returning IMA data from the rpmfi(les) API.
Additionally update the signing code to store the largest IMA signature
length rather than what happened to be last to be on the safe side.
We can't rely on this value due to invalid packages being out there,
but then we need to calculate the lengths on rpmfiles populate so there's
not a lot to gain anyhow.
Fixes: #1833
Combined with 0c1ad364d65c4144ff71c376e0b49fbc322b686d and backported
for 4.16.1.3. Note that the test case has been removed due to it
including a binary file (test package) for which we'd have to use -Sgit
with %autopatch and thus depend on git-core at build time.
Nevertheless, we do have this BZ covered in our internal test suite, so
no need for it anyway.

Subject: [PATCH] Unbreak checking of installed rich dependencies
Commit ddb32b9187e9ce85819a84ca8d202131fd9f8b9f added an
extra check that tests if the provide we are checking really
intersects the dependency from rpmdb. Unfortunately the
rpmdsCompare() call does not understand rich dependencies and
will consider them as not intersecting.
Unbreak the check by not doing the intersection test for
rich dependencies. We'll improve this in a later commit.
Also add test cases for dependency problems with installed
rich dependencies.

Subject: [PATCH] Validate and require subkey binding signatures on PGP public
keys
All subkeys must be followed by a binding signature by the primary key
as per the OpenPGP RFC, enforce the presence and validity in the parser.
The implementation is as kludgey as they come to work around our
simple-minded parser structure without touching API, to maximise
backportability. Store all the raw packets internally as we decode them
to be able to access previous elements at will, needed to validate ordering
and access the actual data. Add testcases for manipulated keys whose
import previously would succeed.
Combined with:
