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.

Comment 2 Vladis Dronov 2022-10-06 16:25:22 UTC 
a test plan:

0) ensure no previous installation and no config and 'rngd' user exists from previous installations

# rpm -e rng-tools jitterentropy
# userdel -r rngd
# rm -f /etc/sysconfig/rngd*

1) grab rngd daemon and jitterentropy lib packages and rngd daemon source rpms from brew via links above

2) install both. please, note this release requires selinux-policy >= 34.1.31-2, it is available in the latest 9.1 composes.

3) verify that a service file DO NOT contain "udevadm" command:

# grep udevadm /usr/lib/systemd/system/rngd.service
<none>

4) verify qrypt is disabled in a config file:

# grep -- '-x qrypt' /etc/sysconfig/rngd
RNGD_ARGS="--fill-watermark=0 -x pkcs11 -x nist -x qrypt -D daemon:daemon"

5) this release does not create any new user/group. still, check that pwck is fine after installation.

# pwck

6) start a service and ensure a process is run as daemon user and a log contains "Process privileges have been dropped" line:
a pause is needed for jitter to init, alternatively you can add "-x jitter" to /etc/sysconfig/rngd to disable jitter.

# systemctl start rngd ; sleep 10 ; systemctl status rngd ; ps -ef | grep rngd

7) [ RUN THIS AFTER STARTING rngd SERVICE AS DESCRIBED IN (6) ABOVE ]
optional: general functional tests. they reside in a source tarball. so rng-tools.src.rpm should be unpacked,
then .tar.gz inside it should be unpacked. go to tests/ in source dir. edit scripts - remove "../" in front of
"rngd" and "rngtest" so binaries installed from the package are used. run tests checking the return code, all
three should return 0:

# ./rngtestzero.sh ; echo $?
# ./rngtesturandom.sh ; echo $?
# RNGD_JITTER_TIMEOUT=60 ./rngtestjitter.sh ; echo $?

8) clean up

# systemctl stop rngd
# dnf -y erase rng-tools jitterentropy
# rm -f rng-tools*rpm jitterentropy*rpm
Comment 3 Vilém Maršík 2022-10-06 16:28:38 UTC 
Thanks for the test plan. What is your question?
Comment 4 Vladis Dronov 2022-10-06 17:43:45 UTC 
No question. As we've agreed on a latest meeting we track bugzilla progress in a bugzilla itself.
So I set needinfo to you when my part is done and I handover a bugzilla to you for testing or verification or when any further actions are needed from your side.
