<pre>Running examples/nft-rule-parse-add.c with the following JSON:
{"rule":{"family":"ip","table":"filter","chain":"input","expr":[{"type":"payload","dreg":1,"offset":9,"len":1,"base":"network"},{"type":"cmp","sreg":1,"op":"eq","data_reg":{"type":"value","len":1,"data0":"0x00000006"}},{"type":"payload","dreg":1,"offset":1,"len":2,"base":"transport"},{"type":"cmp","sreg":1,"op":"eq","data_reg":{"type":"value","len":2,"data0":"0x00001600"}}]}}
The program outputs the JSON to stdout then hangs. If I hit ctrl+c the program
ends. There is no error message.
I've inserted printf statements into the program and can see that the hang
happens on the first call to mnl_socket_recvfrom().
I've tested using libmnl and libnftnl from git repo.</pre>
