RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

cannot install beaker test RPMs in FIPS mode.
Even though I use --nodigest option (or set pkg_verify_level to none) I am getting an error


# rpm --nodigest -iv beaker-distribution-reservesys-3.4-10.noarch.rpm 
Preparing packages...
beaker-distribution-reservesys-3.4-10.noarch
error: unpacking of archive failed on file /mnt/tests/distribution/reservesys/Makefile;5c125eb1: cpio: Digest mismatch
error: beaker-distribution-reservesys-3.4-10.noarch: install failed

# rpm -q rpm cpio
rpm-4.14.2-7.el8.s390x
cpio-2.12-8.el8.s390x

OK, so this is expected as the package installation is failing due to a file-digest

rpm -qp --qf "%{filedigestalgo}\n" beaker-distribution-reservesys-3.4-10.noarch.rpm
(none)

(none) here means md5.

I can bypass that using --nofiledigest option, however there is no macro to disable this check on a system level.

In order to be able to test in FIPS we need to be able to turn this off as our test rpms are built in a way so they are compatible with older RHEL releases.

This isn't about the new package verification at all, this is the install-time per-file verification that exists in all rpm versions. 

The package in question is build with MD5 file digests by overriding the default %_binary_filedigest_algorithm macro value, and since FIPS mode disables that globally so the per-file verification has no chance of succeeding. This is not a bug in rpm, this is just ... FIPS.

Only the EOL'ed RHEL-5 and older needs those MD5 file digests, I'd suggest updating the tests to use the default (sha256) instead.

Closing NOTABUG.
MD5 is not supported hash on RHEL 8 in FIPS mode enabled.
