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 of problem:

The ipcalc utility which is included on the initial installation environment on the Install DVD fails to validate some address/netmask pairs.

I have used it on some kickstart file, in which I validate some user input at the beginning of the installation.

The command

  ipcalc -c 192.168.122.13 255.254.255.0

in the initial environment exits with success status, but it is obviously an incorrect netmask.

The ipcalc utility in Fedora 23 correctly marks this as an error.

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


How reproducible:

Steps to Reproduce:

1. Boot RHEL7.2 install dvd
2. Wait until graphical console, then switch to CLI console (Ctrl-Alt-F2)
3. Enter command "ipcalc -c 192.168.122.13 255.254.255.0"

Actual results:

No output, and exit status 1

Expected results:

ipcalc: bad IPv4 prefix: 255.254.255.0

exit status 1

Additional info:

ipcalc is part of the initscripts package, reassigning.

sounds easy to fix -> devel_ack

Sorry, typo on "Actual results":

exit status is 0, not 1.
