[tracker] Comment added: Kamailio version 3.1.2 crash when memory realloc

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#247 - Kamailio version 3.1.2 crash when memory realloc User who did this - Daniel-Constantin Mierla (miconda) ---------- There is a safety check of realloc with size 0, so this should not happen. I guess you recompiled with fm_malloc support, afaik, 3.1.x is with qm_malloc. Did you get the situation again? Same backtrace? It was reported that libssl can do free(0), so I added recently a check for that case. Probably is unrelated, but maybe it worth trying that patch. ---------- More information can be found at the following URL: https://sip-router.org/tracker/index.php?do=details&task_id=247#comment726 You are receiving this message because you have requested it from the Flyspray bugtracking system.

Kamailio get sip msg from transaction
by Jason Penton 02 Oct '12

02 Oct '12

Hi (Daniel this may be for you re. async) Is it possible to get the sip message from a transaction after using t_continue. The reason I ask is that using the async "pattern", how would one be able to use transactional replies in code using t_reply(code, message). Is the only way to store the sip_msg in shm for later use, because if I look at TM I see there is no storage for the original SIP request? Cheers Jason

TM module. To header is not correct in the CANCEL request.
by Vitaliy Aleksandrov 01 Oct '12

01 Oct '12

According to the TM reparse_invite option description Kamailio should build the CANCEL request from the INVITE message which was sent out instead of building them from the received request. And Kamailio does it for all headers except "To". Kamailio builds "To" header from the received INVITE. Patch to fix it: --- ./kamailio-3.2.3/modules/tm/t_cancel.c 2012-08-22 10:39:21.000000000 +0300 +++ ./kamailio-3.2.3-fixed/modules/tm/t_cancel.c 2012-10-01 18:25:57.000000000 +0300 @@ -284,7 +284,7 @@ if (cfg_get(tm, tm_cfg, reparse_invite)) { /* build the CANCEL from the INVITE which was sent out */ cancel = build_local_reparse(t, branch, &len, CANCEL, CANCEL_LEN, - &t->to + NULL #ifdef CANCEL_REASON_SUPPORT , reason #endif /* CANCEL_REASON_SUPPORT */ It is not a problem when Kamailio doesn't change "To" header or does it before transaction creation (t_relay, t_newtran). To reproduce that situation "To" header should be rewritten in a branch_route. build_local_reparse is also used in t_reply.c to build local ACK requests and passing new "To" header absolutely right there, since "To" header in ACK must be equal to "To" header field in the response being acknowledged. But if I correctly understand rfc3261 it is not correct behaviour for a CANCEL request. P.S. I've checked 3.3.1 sources and haven't found any changes related to this issue.

patch: sdpops - new function remove_line_by_prefix()
by Mikko Lehto 01 Oct '12

01 Oct '12

Hi I created this patch to clean ugly experimental SDP lines. It is tested with Content-Type multipart/mixed and application/sdp and body cleaning seem to work fine. Here is a sample of unwanted SDP attributes that can be filtered with this function: --- a=X-sqn:0 a=X-cap: 1 audio RTP/AVP 100 a=X-cpar: a=rtpmap:100 X-NSE/8000 a=X-cpar: a=fmtp:100 192-194,200-202 a=X-cap: 2 image udptl t38 --- Comments appreciated. -- Mikko Lehto

kamailio core at qm_status

Hi All, I'm observing a core intermittently at "qm_status (qm=0x786cd000) at mem/q_malloc.c:763" for kamailio version 3.1.0 looking at the backtrace this is occurring while doing a tcp buffer overrun.
