Hi Pablo, sorry about the formatting issues.
One thing about your suggestion:

Checking uniquely for the absence of json_root is not enough as
json_echo may have been initialized. In essence, the case the patch is
fixing is when json_root is null but json_echo is not, to denote that we
want json echo output but have not read json from input.
In addition, v5 will contain a check for json_echo initialization inside
monitor.c to avoid re-initializing nft->json_echo when the callback is
built again, this happens when reading multiple times from a mnl socket
(see mnl.c:433 inside mnl_batch_talk).
Regards.
