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:
1. run qemu with '-spice addr=[ipv6::in:brackets],<rest_of_options>'
2. qemu segfaults in getnameinfo()

This may be a bug in spice server that should reject or correct the value of addr= or in getnameinfo() that should be able to cope with such address


Version-Release number of selected component:
qemu-kvm-0.12.1.2-2.355.el6

I don't think spice should use getnameinfo() during initialization. Is there a valid reason for that? For any input from the user (including configuration), getaddrinfo() should be used to gather the necessary data.

During the initialization of a service, the only binary addressing data I could think of would come from the kernel through netlink. But these should rarely be used for any reverse lookup.

This is probably fixed by http://cgit.freedesktop.org/spice/spice/commit/?id=5a31221252b
Pavel, see http://cgit.freedesktop.org/~teuf/spice/commit/?id=79c3a97 for some kind of explanations on the getnameinfo() call (summary: there is such a call in the post-getaddrinfo() loop, but its result is unused)
