Re: [libvirt] [PATCH] util: fix missing broadcast address in bridge and tap device IP addresses

Commit b3d069872ce53eb added peer address setting to the low level virNetDevSetIPAddress() function, but ended up causing a segfault in cases where the caller passed NULL for peer address. Commit a3510e33d33e52c fixed the segfault, but managed to cause us to skip setting the broadcast address when setting an interface's IP address if the peer address was NULL. The result is that the broadcast address is 0.0.0.0 for all libvirt-created bridges (and for now also in interfaces in lxc containers with IP addresses set by libvirt). This was reported on the mailing list: https://www.redhat.com/archives/libvir-list/2016-June/msg00027.html but I was too busy to investigate at the time. I found it by accident today while refactoring virNetDevSetIPAddress(). Since this regression is present in the 1.3.5 release, I'm sending the bugfix as a separate simpler patch from my larger refactoring patchset. --- src/util/virnetdev.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
