[sr-dev] [tracker] Task opened: Crash on call of m_dump() - msilio module.

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Stoyan Mihaylov (stoyan) Attached to Project - sip-router Summary - Crash on call of m_dump() - msilio module. Task Type - Bug Report Category - Modules kamailio Status - Unconfirmed Assigned To - Operating System - Linux Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - My whole configuration is: User client <-> Kamailio <-> Asterisk. Calls and messages are going from user, to Kamailio then to Asterisk server (one or more), back to Kamailio and then to user. When both clients are connected, then there are no problems with messages. When I am sending message to client who is not connected, then messages are stored. When client try to get stored messages, Kamailio crashes. Currently, I cannot send logs, because I found problem, and I solved it on my servers - and I offer potential patch: diff --git a/modules/msilo/msilo.c b/modules/msilo/msilo.c index 209b309..4bda8fa 100644 --- a/modules/msilo/msilo.c +++ b/modules/msilo/msilo.c @@ -1125,8 +1125,16 @@ static int m_dump(struct sip_msg* msg, str* owner_s) memcpy(tmp_extra_hdrs.s, extra_hdrs_str.s, extra_hdrs_str.len); memcpy(tmp_extra_hdrs.s+extra_hdrs_str.len, str_vals[4].s, str_vals[4].len); } else { - tmp_extra_hdrs.len = 0; - tmp_extra_hdrs.s = ""; + tmp_extra_hdrs.len = 0; + if ((tmp_extra_hdrs.s = pkg_malloc(1)) == NULL) + { + LM_ERR("Out of pkg memory"); + if (msilo_dbf.free_result(db_con, db_res) < 0) + LM_ERR("failed to free the query result\n"); + msg_list_set_flag(ml, mid, MS_MSG_ERRO); + goto error; + } + tmp_extra_hdrs.s[0]='\x0'; } hdr_str.len = 1024; if(m_build_headers(&hdr_str, str_vals[3] /*ctype*/, Problem appear when we attempt to free tmp_extra_hdrs.s - in case when we assigned "" to it. Although I allocate (in patch) 1 byte, I set tmp_extra_hdrs.len = 0; to avoid adding wrong headers. When I set tmp_extra_hdrs.len = 1; - I got errors processing message (but no crash of Kamailio). This problem and patch is found in version 3.3.3 and in development version also.
