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 Aleš Koval 2014-11-19 11:20:09 UTC

Squid send malformed PTR query for IPv6 address. This affects logging FQDN.

See http://bugs.squid-cache.org/show_bug.cgi?id=3215

Comment 2 Tomáš Hozza 2014-12-05 13:04:36 UTC

patch is in the upstream bug

Comment 5 Ondřej Pták 2015-06-18 21:57:46 UTC

If squid is configured to log fqdn, there should be hostname instead of host ip. With squid-3.1.10-29, there is correctly hostname displayed in log, but with previous version of squid reverse lookup failed an ip address was displayed instead.

squid.conf (part)
=================
log_fqdn on
logformat fdqn %>A %>Hs "%rm %ru"
access_log /var/log/squid/fdqn.log fdqn
