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 Nilesh Javali (Marvell) 2019-12-23 05:58:07 UTC
Description of problem:
iSCSI IPv6 discovery fails with checksum error on Target side

Version-Release number of selected component (if applicable):
RHEL 8.2 Internal Snapshot 2.1

How reproducible:
100%

Steps to Reproduce:
1. Configure qedi iface with IPv6 settings
2. Perform IPv6 discovery of iSCSI target
3. The discovery fails with checksum error on target side with below messages,

NetApp-EIT-B7-2*> Wed Dec 18 15:38:16 GMT [NetApp-EIT-B7-2: netinet6.icmp.chksum:error]: ICMP6 checksum error (135|c229) 2001:0db2::07d3:819e:3f8d:481b.
Wed Dec 18 15:38:32 GMT last message repeated 7 times
Wed Dec 18 15:38:32 GMT [NetApp-EIT-B7-2: netif.linkDown:info]: Ethernet e0a: Link down, check cable.
Wed Dec 18 15:38:36 GMT [NetApp-EIT-B7-2: netinet6.icmp.chksum:error]: ICMP6 checksum error (135|c229) 2001:0db2::07d3:819e:3f8d:481b.
Wed Dec 18 15:38:36 GMT [NetApp-EIT-B7-2: netif.linkUp:info]: Ethernet e0a: Link up.
Wed Dec 18 15:38:38 GMT [NetApp-EIT-B7-2: netinet6.icmp.chksum:error]: ICMP6 checksum error (135|c229) 2001:0db2::07d3:819e:3f8d:481b. 

Actual results:
IPv6 discovery failure with Checksum Error

Expected results:
IPv6 discovery succeeds without any errors

Additional info:

This is possible regression caused due to recent upstream open-iscsi commit,
af48f0d Out-of-bounds read: Overrunning array of 8 2-byte elements

After reverting this commit, the IPv6 discovery succeeds without any errors.

Comment 1 Chris Leech 2020-01-20 18:56:04 UTC
The change "Out-of-bounds read: Overrunning array of 8 2-byte elements" has been reverted, both upstream and for RHEL 8.2.

Thank you
