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:
Something we ran into when building Rocky Linux 9: python-dns appears to fail tests due to OpenSSL deprecating SHA1+RSA.
Building python-dns against the current openssl-3.0.1-37.el9 fails with an unsupported SHA1 error in the RPM tests. Building against the older openssl-3.0.1-5.el9 appears to work.
The actual error is raised several times, and looks like this:
"""
> raise UnsupportedAlgorithm(
"{} is not supported by this backend for RSA signing.".format(
algorithm.name
),
_Reasons.UNSUPPORTED_HASH,
)
E cryptography.exceptions.UnsupportedAlgorithm: sha1 is not supported by this backend for RSA signing.
"""
Version-Release number of selected component (if applicable):
python-dns-2.1.0-6.el9
How reproducible:
Always
Steps to Reproduce:
1. mock -v -r ~/centos9-x86_64.cfg --resultdir ./ --isolation simple ../src/python-dns-2.1.0-6.el9.src.rpm
Actual results:
cryptography.exceptions.UnsupportedAlgorithm: sha1 is not supported by this backend for RSA signing.
Expected results:
Tests should succeed as normal
Additional info:
Some openssl versions between 3.0.1-5 and 3.0.1-37 may work, I didn't test all of them.
According to the changelog, this might have been broken in openssl-3.0.1-8? "Disable SHA1 signature creation and verification by default"
I think it's likely the python-dns tests need to be updated to support a newer signature method.
version:
python3-dns-2.2.1-2.el9.noarch
Build passed gating and the build landed in nightly. Automated tests passed as well as a sanity check, hence marking the bug verified.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
