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.

Fixed In Version: gnutls-3.7.6-15.el9
Doc Type: Bug Fix
Doc Text:
Cause: HMAC file for gnutls, used for integrity checks in FIPS mode, has been moved to `/usr/lib64/.gnutls.hmac` Consequence: other software relying on HMAC file location wasn't able to locate it. For example, dracut no longer copied it to initramfs, impacting functionality of NetworkManager during early boot in FIPS mode Fix: gnutls HMAC file location has been moved back to `/usr/lib64/.libgnutls.so.30.hmac` Result: gnutls HMAC file is successfully installed into initramfs for machines switched to FIPS mode

Description Jan Pazdziora 2022-11-24 19:56:26 UTC 
Description of problem:

On RHEL 9.0 post-GA, message

[    8.190251] dracut-cmdline[554]: Error in GnuTLS initialization: Error while performing self checks. 

appears on the console when provisioning is run with the fips=1 parameter.

Version-Release number of selected component (if applicable):

gnutls-3.7.6-12.el9_0.x86_64
kernel-5.14.0-70.30.1.el9_0.x86_64
dracut-055-45.git20220404.el9_0.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. Provision RHEL 9.0 post-GA (for example the RHEL-9.0.0-updates-20221124.0 compose) with fips=1 parameter.
2. Check the console output.
3. After installation, run journalctl -l | grep dracut-cmdline

Actual results:

On console:

Expected results:

No GnuTLS related errors.

Additional info:

This does not happen when fips=0 is used.

This did not happen with RHEL 9.0 GA compose which installed

gnutls-3.7.3-9.el9.x86_64
kernel-5.14.0-70.13.1.el9_0.x86_64

Comment 8 Alexander Sosedkin 2022-11-30 15:18:33 UTC 
Note: reproducing this requires `dracut-network` package installed, which pulls in nmcli, which pulls in gnutls.
