Previously, this triggered a program abort:
| # nft add table ip t
| # nft add set ip t my_set '{ type ipv4_addr . inet_service ; flags interval ; }'
| # nft add element ip t my_set '{10.0.0.1 . tcp }'
| BUG: invalid range expression type concat
| nft: expression.c:1085: range_expr_value_low: Assertion `0' failed.
With this patch in place, the 'add set' command above gives an error
message:
| # nft add set ip t my_set3 '{ type ipv4_addr . inet_service ; flags interval ; }'
| Error: concatenated types not supported in interval sets
| add set ip t my_set3 { type ipv4_addr . inet_service ; flags interval ; }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
