Patches applied to F20 in Fedora git.  Rawhide already has the upstream commits and F19 should pick the fixes up when it rebases today.

Just a heads up: the fix for this is likely to break Zebra.  I haven't seen any sensible ideas for how to fix that yet.  DaveM seems to favor changing Zebra.

Comment 7 Josh Boyer 2014-05-12 17:07:25 UTC

This introduced a regression with Quagga (bug 1097684).  I've backported the upstream fix below to address that.  FYI to anyone paying attention.
