Hi,

http_reply_parse is not present in the configs. I've explicitly set it as "no" and the result is the same. If I set it as "yes", topos complains like this:

Jan 22 15:00:10 proxy1 kamailio[29316]: ERROR: topos [topos_mod.c:282]: tps_prepare_msg(): cannot parse cseq header

Thank you,

Nuno

Hello,

do you have http_reply_parse=yes ?

The error is from topos catching the http reply being sent out and trying to handle it.

Cheers,
Daniel

Hello,

what version of kamailio are you using and what http version is curl using? Can you paste here the http request taken with ngrep from the network?

Hi Daniel,

There's no other traffic than the HTTP requests.

This comment in src/core/parser/parse_fline.c 99 - 113, caugh my attention:

 } else if (http_reply_parse != 0 &&
(*tmp=='H' || *tmp=='h') &&
/* 'HTTP/1.' */
strncasecmp( tmp+1, HTTP_VERSION+1, HTTP_VERSION_LEN-1)==0 &&
/* [0|1] */
((*(tmp+HTTP_VERSION_LEN)=='0') || (*(tmp+HTTP_VERSION_LEN)=='1')) &&
(*(tmp+HTTP_VERSION_LEN+1)==' ')  ){
/* ugly hack to be able to route http replies
* Note: - the http reply must have a via
*       - the message is marked as SIP_REPLY (ugly)
*/
fl->type=SIP_REPLY;
fl->flags|=FLINE_FLAG_PROTO_HTTP;
fl->u.reply.version.len=HTTP_VERSION_LEN+1 /*include last digit*/;
tmp=buffer+HTTP_VERSION_LEN+1 /* last digit */;

and later in error1:

error1:
fl->type=SIP_INVALID;
LOG((core, core_cfg, corelog), "parse_first_line: bad message (offset: %d)\n", offset);
/* skip  line */
nl=eat_line(buffer,len);
return nl;

So that log line can be conditional if FLINE_FLAG_PROTO_HTTP is not part of fl->flags.

I just don't know where the "[466B blob data]" is getting printed

Hello,

as I said, watch the traffic on port 8000 with ngrep or some other network sniffer to see what data comes there. You can also start kamailio with debug=3 in config, more debug logs should be printed to syslog to get the context of what is processed at that time.

Cheers,
Daniel

Hi Daniel,

Thanks for your feedback.

I have a dedicated listen directive for JSONRPC

listen = 127.0.0.1:8000

and then an event_route for it:

event_route[xhttp:request] {
    if ($Rp != 8000) {
        xhttp_reply("403", "Forbidden", "text/html", "<html><body>Forbidden</body></html>");
        exit;
    }
    if ($hu =~ "^/RPC") {
        jsonrpc_dispatch();
    } else {
        xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL $hu</body></html>");
    }
    return;
}

So, I'm already doing HTTP traffic only in port 8000.

The interesting part is that if I use kamcmd pl.list pipe_INVITE, only the first log line is printed. Using curl, I see the other 2 logs all the time.

Thank you

Hello,

can you want the traffic on port 8000 and see if there is no "unexpected" traffic there? There should be no error message for parsing the first line of an HTTP request.

The error message related the missing pipe can be made debug.

Daniel

Hi all,

I'm using pipelimit with the "clean_unused" option to get rid of pipes that are not used for quite some time. At the same time we are monitoring pipelimit with a jsonrpc call similar to:

# curl --header 'Content-Type: application/json' --data-binary '{"id": 1, "jsonrpc": "2.0", "method": "pl.list", "params": ["pipe_INVITE"]' http://127.0.0.1:8000/RPC

Reply:

{
   "jsonrpc": "2.0",
   "error": {
      "code": 400,
      "message": "Unknown pipe id pipe_INVITE"
   },
   "id": 1

}

The above reply is valid because the pipe_INVITE was not loaded yet, but the request makes kamailio to log the following log messages:

Jan 20 11:21:48 proxy1 kamailio[24474]: ERROR: pipelimit [pl_ht.c:519]: rpc_pl_list(): no pipe: pipe_INVITE
Jan 20 11:21:48 proxy1 kamailio[24474]: ERROR: <core> [core/parser/parse_fline.c:262]: parse_first_line(): parse_first_line: bad message (offset: 20)
Jan 20 11:21:48 proxy1 kamailio[24474]: [466B blob data]

Since the monitoring system does periodic requests, those log lines get a bit annoying and fill the log with ERROR messages that aren't really errors.

IMHO the first log line should be converted to DEBUG instead of ERROR, but I have some doubts about the one from parse_fline.c:262. parse_first_line() is used to process both SIP and HTTP. It makes sense to log ERROR if SIP but not in the case of HTTP...

Regarding the "[466B blob data]" I really don't know from where it's coming from.

I can submit a PR, but I would like to have first some feedback from you.

Thank you,

Nuno
