Description Eduardo Habkost 2009-04-16 19:10:01 UTC

Warnings from rpmdiff:

VERIFY	 	kvm	 	usr/bin/qemu-kvm on x86_64 uses function gethostbyname, which may impact IPv6 support
VERIFY	 	kvm	 	usr/bin/qemu-kvm on x86_64 uses function inet_aton, which may impact IPv6 support
VERIFY	 	kvm	 	usr/bin/qemu-kvm on x86_64 uses function inet_ntoa, which may impact IPv6 support
VERIFY	 	kvm	 	usr/bin/qemu-nbd on x86_64 uses function gethostbyname, which may impact IPv6 support
VERIFY	 	kvm	 	usr/bin/qemu-nbd on x86_64 uses function inet_aton, which may impact IPv6 support
VERIFY	 	kvm-qemu-img	 	usr/bin/qemu-img on x86_64 uses function gethostbyname, which may impact IPv6 support
VERIFY	 	kvm-qemu-img	 	usr/bin/qemu-img on x86_64 uses function inet_aton, which may impact IPv6 support


I don't know if they are real issues, but it would be a good idea to check them.

More information about the rpmdiff test can be found on bug #199157.

Comment 1 Daniel Berrangé 2009-04-16 19:20:15 UTC

These all need fixing, regardless of IPv6 support - nothing should use gethostbyname() under any circumstance anymore. In addition to lacking credible IPv6 support, it is not threadsafe, and do not return the results in a usefully sorted order.

Gerd had previously converted most of QEMU to use getaddrinfo()/getnameinfo(). We just need to complete the job and kill off gethostname() and inet_aton/ntoa too. The following guide demonstrates how to kill off these obsolete functions http://people.redhat.com/drepper/userapi-ipv6.html

Comment 2 RHEL Program Management 2009-06-22 18:47:22 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 3 Eduardo Habkost 2010-01-20 11:53:17 UTC

On RHEL-6, the KVM userspace package is named "qemu-kvm". Moving bug to the right component.

Comment 6 Eduardo Habkost 2010-11-19 14:09:37 UTC

This is something that should be addressed upstream first. Postponing again.
