src: enable json echo output when reading native syntax
This patch fixes a bug in which nft did not print any output when specifying --echo and --json and reading nft native syntax. This patch respects behavior when input is json, in which the output would be the identical input plus the handles. Adds a json_echo member inside struct nft_ctx to build and store the json object containing the json command objects, the object is built using a mock monitor to reuse monitor json code. This json object is only used when we are sure we have not read json from input. [ added json_alloc_echo() to compile without json support --pablo ] Fixes: https://bugzilla.netfilter.org/show_bug.cgi?id=1446 Signed-off-by: Jose M. Guisado Gomez <guigom@riseup.net> Tested-by: Eric Garver <eric@garver.life> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
