Missing *.hmac files in FIPS initramfs
Last modified: 2013-02-28 23:11:34 EST
Description of problem:
Seems that dracut doesn not put FIPS *.hmac filer in initramfs, so fipscheck verification cannot succeed.
Version-Release number of selected component (if applicable):
Easy to test, just install crypt module dracut -f -a crypt and try to run cryptsetup in initramfs "cryptsetup status x" - it will fail with FIPS check failed.
Hm, this should be perhaps F17 bug only and related only to cryptsetup.
I'll post more info ASAP, seems my system is kind of broken now...
I think the problem is that hmac location changes (seems not for all packages though) to /lib/fipscheck:
# ls /lib64/fipscheck
cryptsetup.hmac fipscheck.hmac libcryptsetup.so.4.3.0.hmac libcryptsetup.so.4.hmac libfipscheck.so.1.1.0.hmac libfipscheck.so.1.hmac sshd.hmac ssh.hmac

Log from dracut -f -v --debug -a crypt
Hmmm. this change is 2 years old.. I wonder if cryptsetup is the first real user of fipscheck in initramfs? :)

Similar change was in RHEL6 but somehow disappeared on the way...
