[libvirt] [PATCH] build: require netcf-0.2.2 when installing on Fedora18+
A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the install-time Requires: for netcf has always been implicit due to libvirtd linking with libnetcf.so. However, the since the API of netcf didn't change when it was rebuilt to use libnl-3, the internal library version didn't change either, making it possible (from rpm's point of view) to upgrade libvirt without upgrading netcf (in reality, that leads to a segfault - see https://bugzilla.redhat.com/show_bug.cgi?id=853381). The solution is to put an explicit Requires: line in libvirt's specfile for fedora >= 18 and rhel >= 7. --- libvirt.spec.in | 3 +++ 1 file changed, 3 insertions(+) diff --git a/libvirt.spec.in b/libvirt.spec.in index 9a1feed..cc5247b 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -589,6 +589,9 @@ Requires: iptables-ipv6 %if %{with_nwfilter} Requires: ebtables %endif +%if %{with_netcf} && (0%{?fedora} >= 18 || 0%{?rhel} >= 7) +Requires: netcf-libs >= 0.2.2 +%endif # needed for device enumeration %if %{with_hal} Requires: hal -- 1.7.11.4

Thanks. Pushed - we should push this same change into the f18 and rawhide builds of libvirt on Fedora (there's even an appropriate BZ, but bugzilla is currently down so I'll have to make a reminder on my todo list to update it later).
