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:
Now we only support the non-local scope ipv6 protocol. Track the ipv6 new feature to support local scope ipv6 protocol. 

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


How reproducible:


Steps to Reproduce:

Actual results:


Expected results:


Additional info:

When dumping to ssh via local ipv6 address, the ssh parameter
in kdump.conf is supposed to have the form like

ssh user@fe80::cc1:8bff:fe90:b95f%eth0

where "%eth0" is an existing network interface supporting ipv6.

However, the get_remote_host function in kdump-lib.sh currently
doesn't remove the network interface in the ipv6 address,
causing the ip command in kdump_install_net function to fail,
leading to a "Bad kdump location" message.
