[PATCH nft] parser_json: fix crash on add rule to bad references

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pass the location via the handle so the error leg in
rule_translate_index() can reference it. Applies to invalid references
to tables, chains, and indexes.
