Thanks for great analysis, report and patch! Would you like to push it to gerrit? See [1] and [2] Adding Dan in case you do not want to, so that your patch isn't lost... > > Hope this helps to find the root cause.... Not sure what you mean - did you have any other problem after applying your patch? Seems to me that the root cause is some code (the part you patched or something earlier) did not expect a prefix of /32, which is indeed quite rare. Not even certain how it works - did you also get a default gateway? How can you access it, if it's not in your subnet?
