"ip route table list main" showed my the route just fine but /proc/net/route was an empty file. What was going on? Thinking it was a bug in something I did and I looked deeper. Eventually I setup a second route and everything looked correct, huh? Finally I realized that the it was just the iterator pair in fib_trie_get_first, fib_trie_get_next just could not handle a routing table with a single entry. So to save myself and others further confusion, here is a simple fix for the fib proc iterator so it works even when there is only a single route in a routing table. Signed-off-by: Eric W.
