            Bug ID: 1319
           Summary: Exporting a map with many elements to JSON will fail
           Product: nftables
           Version: unspecified
          Hardware: x86_64
                OS: RedHat Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: nft
          Assignee: pablo at netfilter.org
          Reporter: mizuno at axsh.net

When exporting a map with many(more than 32?) elements to JSON, broken JSON
will be output.


nft "add table ip ttt"
nft "add map ip ttt my_map { type ipv4_addr : ipv4_addr ; }"
for i in $(seq 1 33); do
  nft "add element ip ttt my_map { 203.0.113.${i} : }"

nft export json | jq .nftables

The above script throws the following error:

  parse error: Unmatched ']' at line 1, column 4257

This error can be avoided by rewriting the last line as follows:

  nft export json | sed 's/]}$/}]}/' | jq .nftables

It seems to be caused by missing closing } of the "set" object.

% nft --version
nftables v0.8 (Joe Btfsplk)
