Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Alicja Kario 2018-07-19 17:26:32 UTC 
Description of problem:
When system is working in FIPS mode, only specific key sizes are allowed, asking openssl for generation of other key sizes causes it to report confusing error message "q not prime" instead of the expected "key size invalid"

Version-Release number of selected component (if applicable):
openssl-1.0.2k-15.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. turn system to FIPS mode
2. openssl dsaparam -out dsa-test.pem 2047

Actual results:
Generating DSA parameters, 2047 bit long prime
This could take some time
140075572418448:error:0A07B071:dsa routines:dsa_builtin_paramgen:q not prime:dsa_gen.c:165:
Error, DSA key generation failed

Expected results:
Generating DSA parameters, 2047 bit long prime
This could take some time
140178529699744:error:0A07B071:dsa routines:dsa_builtin_paramgen:key size invalid:dsa_gen.c:167:
Error, DSA key generation failed

Additional info:
while technically a regression (openssl-1.0.1e-60.el7.x86_64 was behaving correctly), it's only an issue in error message
