The ip -j option to print output as JSON is ignored when using 'route get':
$ ip -j route get 127.0.0.1 local 127.0.0.1 dev lo src 127.0.0.1 uid 1000 cache <local> Enable JSON output in iproute_get(), and don't let print_cache_flags() close the JSON output, as it's not always the last called JSON function. Tested on different route types: $ ip -j -p route get 127.0.0.1 [ { "type": "local", "dst": "127.0.0.1", "dev": "lo", "prefsrc": "127.0.0.1", "flags": [ ], "uid": 1000, "cache": [ "local" ] } ] $ ip -d -j -p route get 192.0.2.1 [ { "type": "unicast", "dst": "192.0.2.1", "gateway": "192.168.85.1", "dev": "wlp3s0", "table": "main", "prefsrc": "192.168.85.2", "flags": [ ], "uid": 1000, "cache": [ ] } ] Fixes: 663c3cb23103 ("iproute: implement JSON and color output") Acked-by: Phil Sutter <p...@nwl.cc> Reviewed-and-tested-by: Andrea Claudi <acla...@redhat.com> Signed-off-by: Matteo Croce <mcr...@redhat.com> --- ip/iproute.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/ip/iproute.c b/ip/iproute.c index e091927b..2b3dcc5d 100644 --- a/ip/iproute.c +++ b/ip/iproute.c @@ -450,10 +450,8 @@ static void print_cache_flags(FILE *fp, __u32 flags) if (flags) print_hex(PRINT_ANY, "flags", "%x>", flags); - if (jw) { + if (jw) jsonw_end_array(jw); - jsonw_destroy(&jw); - } } static void print_rta_cacheinfo(FILE *fp, const struct rta_cacheinfo *ci) @@ -2079,6 +2077,8 @@ static int iproute_get(int argc, char **argv) if (rtnl_talk(&rth, &req.n, &answer) < 0) return -2; + new_json_obj(json); + if (connected && !from_ok) { struct rtmsg *r = NLMSG_DATA(answer); int len = answer->nlmsg_len; @@ -2123,6 +2123,7 @@ static int iproute_get(int argc, char **argv) req.n.nlmsg_flags = NLM_F_REQUEST; req.n.nlmsg_type = RTM_GETROUTE; + delete_json_obj(); free(answer); if (rtnl_talk(&rth, &req.n, &answer) < 0) return -2; @@ -2134,6 +2135,7 @@ static int iproute_get(int argc, char **argv) return -1; } + delete_json_obj(); free(answer); return 0; } -- 2.20.1
