When latest Kamailio git master sends a message over WebSocket (specifically an MSRP reply on my test system) I get the error, One or more reserved bits are on: reserved1 = 1, reserved2 = 0, reserved3 = 0 in Google Chrome. This happens for WebSockets over TCP and WebSockets over TLS. It doesn't happen with a build of Kamailio git master from around two weeks ago. Have there been any changes in the network code over the last couple of weeks that might have had an effect on what Kamailio puts out on the wire for TCP and TLS? The code to send an MSRP reply over WebSocket is in modules/msrp/msrp_netio.c:msrp_reply() if (unlikely((env->srcinfo.proto == PROTO_WS || env->srcinfo.proto == PROTO_WSS) && sr_event_enabled(SREV_TCP_WS_FRAME_OUT))) { struct tcp_connection *con = tcpconn_get(env->srcinfo.id, 0, 0, 0, 0); ws_event_info_t wsev; if (con == NULL) { LM_WARN("TCP/TLS connection for WebSocket could not be" "found\n"); return -1; } memset(&wsev, 0, sizeof(ws_event_info_t)); wsev.type = SREV_TCP_WS_FRAME_OUT; wsev.buf = rplbuf; wsev.len = p - rplbuf; wsev.id = con->id; return sr_event_exec(SREV_TCP_WS_FRAME_OUT, (void *) &wsev); } The code that handles the SREV_TCP_WS_FRAME_OUT event is in modules/websocket/ws_frame.c and basically involves: * filling in the WebSocket message header * identifying the correct TCP/TLS connection * setting some flags (for example, SND_F_FORCE_CON_REUSE) * calling tcp_send() These areas of the code haven't been changed for months.

Kamailio segfaulting early in start-up with Kamailio git master

by Peter Dunkley

When I have explicit listen directives like this (PRIV_IP_ADDR is a substdef included from another file): listen=tcp:"PRIV_IP_ADDR":80 listen=tls:"PRIV_IP_ADDR":443 listen=tls:"PRIV_IP_ADDR":2855 Kamailio seg-faults very early in start-up.

[tracker] Task opened: Segfault in ims_auth's ims_proxy_authenticate function when IMPU != IMPI (Attachment added)

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Camille Oudot (coudot) Attached to Project - sip-router Summary - Segfault in ims_auth's ims_proxy_authenticate function when IMPU != IMPI Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - Medium Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - If a client sends an INVITE with no Proxy-Authorization header, and this request is challenged using ims_proxy_authenticate(), ims_auth module tries to use the address in From header as IMPI for the MAR diameter request. When IMPI != IMPU, the HSS replies with an error code since the user cannot be found. In that case the SIP-Auth-Data-Item AVP isn't found in the MAA answer, and avlist is never initialized in async_cdp_callback(). Adding a safety check in the "done" section prevented the crash to occur (see attached patch). One or more files have been attached.

[tracker] Comment added: modules/debugger: be able to log assign actions

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#299 - modules/debugger: be able to log assign actions User who did this - Daniel-Constantin Mierla (miconda) ---------- dbg_enable_log_assign() is wrong, because _dbg_pvcache is not-NULL always as you declared it in this version. Perhaps you have to add have more values for log_assign, like: - 0 - completely disabled - 1 - feature enabled, but not active - 2 - feature enabled and active (could be 3 if you want to use bits) It opens the way to make it changeable at runtime via rpc (only to make it active/inactive), if set to 0, should not be changeable. The dbg pv cache should not keep pvid field, the pointer is long and can be compared directly. For strings makes sense to have an integer id, as strcmp() can be lengthy operation. Here just go and compare the pointers, values are taken in one bus fetch. Also, you do the hash function over the content of pvspec, not the pointer value, which you try to find. Although it may work, is not that natural. The hash should be over the value that is searched. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=299#comment913 You are receiving this message because you have requested it from the Flyspray bugtracking system.
