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:
Submitting per customer request. This could really be defined as a bug or an RFE depending on your perspective on this.
Unable to add ipsets with brackets per ipv6 RFC, using syntax such as[::2]
Version-Release number of selected component (if applicable):
Any version of RHEL 7 and 8 I was unable to add with brackets. Customer stated they were able to get it to work but did not specify a specific RHEL or Fedora release I was unable to get ipset addition with brackets to work on RHEL 7.7 or 8.1
How reproducible:
Just about always in my experience. Customer states it works in some cases
Steps to Reproduce:
1. firewall-cmd --permanent --new-ipset=test --type=hash:net --option=family=inet6
2. firewall-cmd --permanent --ipset=test --add-entry=[::2] OR ipset add test [::2]
3.
Actual results:
(in my testing)
[root@localhost ~]# firewall-cmd --permanent --ipset=test --add-entry=[::1]
Error: INVALID_ENTRY: invalid address '[::1]' in '[::1]' for hash:net (ipv6)
Expected results: success code such as:
[root@localhost ~]# firewall-cmd --permanent --ipset=test --add-entry=::1
success
Additional info:
Customer's reasoning is that per RFCs about ipv6 syntax use brackets and this implies that using brackets in ipv6 syntax is a standard that firewalld should adhere to.. I was not provided a specific RFC source from the customer but I found something that seemed vaugely relevant but not directly https://tools.ietf.org/rfc/rfc2732.txt
