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 Steve Grubb 2013-10-01 15:49:31 UTC 
+++ This bug was initially created as a clone of Bug #1012626 +++

Description of problem:
The current FIPS-140 certification needs some updates so that we can continue the certification.

We need have a stable file location for fips product determination. NIST has new requirements that causes us to need to define the FIPS module as the crypto system + the dracut-fips package. Libraries and applications will need to look for the presence of the file to know that this is a FIPS product rather than an ordinary product. On RHEL6 & 7 the dracut-fips files moved around a lot. So, its hard to have a solution for both OS.
Comment 4 Harald Hoyer 2013-10-02 10:07:34 UTC 
dracut-033-4.el7

changed the file from /etc/redhat-fips to /etc/system-fips
Comment 6 Ladislav Jozsa 2014-03-24 11:58:21 UTC 
Verified with dracut-033-150.el7, RHEL-7.0-20140320.0.

/etc/system-fips present, see c#4.

I did inspection inside the running initramfs with the following results.

gcm modules:
gcm(aes)
gcm(aes-aesni)
# cat /proc/modules | grep -w gcm
gcm 23457 0 - Live 0xffffffffa0257000

# dmesg | grep -w gcm
[   13.047514] alg: self-tests for gcm_base(ctr(aes-asm),ghash-generic) (gcm(aes)) passed
[   13.047873] alg: self-tests for gcm(aes) (gcm(aes)) passed

cts modules:
cts(cbc(aes)
cts(cbc(aes-aesni))

# cat /proc/modules | grep -w cts
cts 12854 0 - Live 0xffffffffa022d000

no match for cts in dmesg | grep -w cts

ctr module:
ctr(aes-aesni)

no module named ctr, however dmesg | grep -w ctr reveals:

[   13.015579] alg: self-tests for ctr(aes-asm) (ctr(aes)) passed
[   13.015866] alg: self-tests for ctr(aes) (ctr(aes)) passed
[   13.035801] alg: self-tests for rfc3686(ctr(aes-asm)) (rfc3686(ctr(aes))) passed
[   13.036102] alg: self-tests for rfc3686(ctr(aes)) (rfc3686(ctr(aes))) passed
[   13.047514] alg: self-tests for gcm_base(ctr(aes-asm),ghash-generic) (gcm(aes)) passed
[   13.058113] alg: self-tests for ccm_base(ctr(aes-asm),aes-asm) (ccm(aes)) passed
[   13.079691] alg: self-tests for rfc4309(ccm_base(ctr(aes-asm),aes-asm)) (rfc4309(ccm(aes))) passed

Steve, is it ok?

As best as I can tell, it looks OK. If we have any more changes, we'll address it on RHEL 7.1. Thanks.
