            Bug ID: 1198
           Summary: nft crashes on empty interface name
           Product: nftables
           Version: unspecified
          Hardware: x86_64
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: nft
          Assignee: pablo at netfilter.org
          Reporter: uzytkownik2 at gmail.com

I don't know how this corrupting happened in my rules but if the iffname is
an
empty string ("") nft crashes on assert strlen(...) > 0 instead of
printing
error.
