From: Petr Štetiar Date: Sun, 12 Jan 2020 21:40:18 +0000 (+0100) Subject: blobmsg_json: fix int16 serialization X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f0da3a4283b7d1192de5c7e620df9381cd5a724b;p=project%2Flibubox.git blobmsg_json: fix int16 serialization int16 blobmsg type is currently being serialized as uint16_t due to missing cast during JSON output. Following blobmsg content: bar-min: -32768 (i16) bar-max: 32767 (i16) Produces following JSON: { "bar-min":32768,"bar-max":32767 } Whereas one would expect: { "bar-min":-32768,"bar-max":32767 } Reviewed-by: Jo-Philipp Wich Signed-off-by: Petr Štetiar --- diff --git a/blobmsg_json.c b/blobmsg_json.c index 1859211..aee7a64 100644 --- a/blobmsg_json.c +++ b/blobmsg_json.c @@ -249,7 +249,7 @@ static void blobmsg_format_element(struct strbuf *s, struct blob_attr *attr, boo sprintf(buf, "%s", *(uint8_t *)data ?
