[kamailio/kamailio] tcp_timer_check_connections() logs on CRITICAL and is not caught by event_route[tcp:timeout] (Issue #3995)

by Fritjof Höst

### Description Hi! We are in the progress of upgrading from Kamailio 5.5 to 5.8. During our testing we have noticed a new error being reported from Kamailio. We don’t see any other errors following it. ```jsx /usr/sbin/kamailio[201]: CRITICAL: <core> [core/tcp_main.c:5544]: tcp_timer_check_connections(): message processing timeout on connection id: 67896 (state: 3) - closing ``` It does seem to be [new code](https://github.com/kamailio/kamailio/blob/master/src/core/tcp_main.c#… in Kamailio reporting this issue. Given that this is a fairly expected thing, cleaning up a connection which receives no traffic within the given time, is there a need for it to be reported on CRITICAL? I’d also expect it to be caught by ``` event_route[tcp:timeout] { xlog("L_INFO","connection $conid timeouts (unanswered keepalives)"); } ``` given that [the description](https://www.kamailio.org/docs/modules/stable/modules/tcpops.ht… of this one is `Called for connection timeouts (unanswered keepalives).`. ### Troubleshooting We don't have any way to reproduce it, we are still investigating it to figure out the cause. It happens around every 2 hours, so we think there might some some scheduled test or job running in our test system causing this. ### Additional Information * **Kamailio Version** - 5.8.3 * **Operating System**: Debian 12 AMI from the AWS Marketplace. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3995 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Possibly adjusting the SDP parser to be more lenient towards scenarios where a stream is being removed/rejected and connection-information "c=" is only available per media (no session-wide "c=") and the removed/rejected stream omits all fields (Issue #3982)

by thomas414

### Description I encountered an issue with a specific device that is receiving a T.38 fax. The call gets established towards the device normally with inband media, then the device requests T.38 media and tries to remove the audio media via sending port 0 in the ReInvite SDP. Also it sends connection-information only on the media level and there is no "c=" on the session level. Reading through the related RFCs and the kamailio code and discussing this on the mailing list, we came to the conclusion that kamailio is doing everything correct as per RFC. Though we were wondering if it would be possible to adjust the parser to be not as strict as it is right now, and allow a missing "c=" line on the media-level if the stream is removed/rejected via port 0, since i see no sense in requiring connection information. Of course we are also in contact with the vendor to hopefully adjust on their side. Here are the related RFCs: 1. RFC8866 5.7 `A session description MUST contain either at least one "c=" line in each media description or a single "c=" line at the session level. It MAY contain a single session-level "c=" line and additional media-level "c=" line(s) per-media-description, in which case the media-level values override the session-level settings for the respective media.` 2. RFC3264 8.2 `Existing media streams are removed by creating a new SDP with the port number for that stream set to zero. The stream description MAY omit all attributes present previously, and MAY list just a single media format.` At first i was especially confused by the RFC3264 8.2 part, since it seemed correct what the device is sending, but if you read carefully and keep the wording for SDP in mind only attributes ("a=") MAY be omitted. So a "c=" line should still be in the SDP for the removed media if it's not included on the session-level. Or do you see this differently? ### Expected behavior Kamailio allows and parses the SDP when there is no session-wide "c=", a media stream is being removed via port zero and there is no "c=" for this media stream and only the remaining media streams include a "c=" line. #### Actual observed behavior Kamailio throws an error when trying to parse the SDP. #### Log Messages ``` <core> [core/parser/sdp/sdp.c:523]: parse_sdp_session(): can't find media IP in the message ``` #### SIP Traffic ``` v=0 o=xmserver 1726638425 1726638427 IN IP4 169.254.1.1 s=xmserver t=0 0 m=audio 0 RTP/AVP 8 m=image 56002 udptl t38 c=IN IP4 169.254.1.1 a=sendrecv a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval:0 a=T38FaxTranscodingMMR:0 a=T38FaxTranscodingJBIG:0 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:200 a=T38FaxMaxDatagram:72 a=T38FaxUdpEC:t38UDPRedundancy ``` ### Possible Solutions ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.3 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 12.2.0 ``` * **Operating System**: ``` Debian 12 Linux hostname 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3982 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] cdp: disconnect_serviced_peer Causing the service process to crash (Issue #3999)

by liangbaolin

### Description hi, I encountered a problem where the CDP module is extremely prone to process crashes. The following are screenshots of the logs and core files. I couldn't find the exception code that caused the problem, but I suspect that the TCP link was properly established, but the peer did not initialize or handle the exception properly, resulting in an exception when the packet was parsed incorrectly and disconnected later. In addition, since the socket is not a normal peer, it will constantly rebuild the chain, but the CDP does not recognize and process it properly. The socket will continue to grow, but the number of peers will not increase. <img width="1508" alt="微信图片_20241011175120" src="https://github.com/user-attachments/assets/88a0fc31-9ff6-4f46-9394-f49c7878…"> ### Troubleshooting #### Reproduction  #### Debugging Data ``` Core was generated by `/usr/sbin/kamailio -f /etc/kamailio_dra/kamailio_dra.cfg -P /var/run/kamailio_d'.

[kamailio/kamailio] Module snmpstats reporting inconsistent call success metrics on intense peaks of failed calls (Issue #4006)

by igorpotjevlesh

### Description We are plotting the call success rate on each of our proxies. Using the Kamailio snmpstats module, we try to obtain three counters in order to plot them on a graph: - Total Calls - Active Calls - Error Calls Most of the time, everything works well and we obtain sensible values: `snmpwalk -c mycommunity -v 2c W.X.Y.Z 1.3.6.1.4.1.34352.3.1.3.1.3.2 -O n` > .1.3.6.1.4.1.34352.3.1.3.1.3.2.1.0 = Gauge32: 309 -> Total Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.2.0 = Gauge32: 95 -> Active Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.3.0 = Gauge32: 214 -> Error calls However, **when our proxies are facing intense peaks of failed calls in a short timespan**, sometimes, the **"Error Calls"** counter returns a value **higher than "Total Calls"**. As a result, **"Active Calls"** suddenly reaches a value close to the **maximum of a _Gauge32_** (because ${TotalCalls} - {ErrorCalls} < 0$). `snmpwalk -c mycommunity -v 2c W.X.Y.Z 1.3.6.1.4.1.34352.3.1.3.1.3.2 -O n` > .1.3.6.1.4.1.34352.3.1.3.1.3.2.1.0 = Gauge32: 153 -> Total Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.2.0 = Gauge32: 4294967226 -> Active Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.3.0 = Gauge32: 223 -> Error calls As a result, our graphs make no more sense. ### Troubleshooting There seems to be a bug causing Total calls to be lower than Error calls when a high number of failed calls are received in a short time window. Moreover, there is an integer overflow resulting to the negative result of the substraction being converted to a _Gauge32_. Maybe setting it to 0 in case of a negative result would be safer ? #### Reproduction Using the following configuration for the snmpstats module of your Kamailio proxy: ``` # -------- snmpstats params ------- modparam("snmpstats", "snmpgetPath", "/usr/bin/") modparam("snmpstats", "snmpCommunity", "mycommunity") modparam("snmpstats", "sipEntityType", "proxyServer") ``` On intense peaks of failed calls, get the call success metrics using `snmpwalk` : `snmpwalk -c mycommunity -v 2c W.X.Y.Z 1.3.6.1.4.1.34352.3.1.3.1.3.2 -O n` > .1.3.6.1.4.1.34352.3.1.3.1.3.2.1.0 = Gauge32: 153 -> Total Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.2.0 = Gauge32: 4294967226 -> Active Calls .1.3.6.1.4.1.34352.3.1.3.1.3.2.3.0 = Gauge32: 223-> Error calls ### Additional Information **Kamailio Version**: `kamailio -v` > version: kamailio 5.6.4 (x86_64/linux) a004cf flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_ MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_S R_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, U SE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SI ZE 65535, DEFAULT PKG_SIZE 64MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a004cf compiled on 16:10:41 May 22 2023 with gcc 4.4.7 * **Operating System**: `uname -r` > 2.6.32-279.el6.x86_64 `lsb_release -a` > LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 6.3 (Santiago) Release: 6.3 Codename: Santiago -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4006 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Memory usage increases everytime tls.reload is executed (Issue #3823)

by Sebastian Denz

### Description We are using Kamailio 5.7.4 on Debian 12 (from http://deb.kamailio.org/kamailio57) with rtpengine as an Edgeproxy for our clients. The instance terminates SIP/TLS (with Cliencertificates) and forwards the SIP Traffic to internal systems. After some days we are getting errors like this `tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: shm=7318616 threshold1=8912896` First we thought Kamailio just doesnt have enough memory, so we doubled it.. But after some days the Logmessage (and Userissues) occured again. So we monitored the shmmem statistics and found that used and max_used are constantly growing til it reaches the limit. As i mentioned we are using client-certificates and so we are also using the CRL feature. We do have a systemd-timer which fetches the CRL every hour and runs 'kamcmd tls.reload' when finished. Our tls.cfg looks like this: ``` [server:default] method = TLSv1.2+ private_key = /etc/letsencrypt/live/hostname.de/privkey.pem certificate = /etc/letsencrypt/live/hostname.de/fullchain.pem ca_list = /etc/kamailio/ca_list.pem ca_path = /etc/kamailio/ca_list.pem crl = /etc/kamailio/combined.crl.pem verify_certificate = yes require_certificate = yes [client:default] verify_certificate = yes require_certificate = yes ``` After testing a bit we found that every time tls.reload is executed Kamailio consumes a bit more memory which eventually leads to all the memory being consumed which leads to issues for our users. See following example: ``` [0][root@edgar-dev:~]# while true ; do /usr/sbin/kamcmd tls.reload ; /usr/sbin/kamcmd core.shmmem ; sleep 1 ; done Ok. TLS configuration reloaded. { total: 268435456 free: 223001520 used: 41352552 real_used: 45433936 max_used: 45445968 fragments: 73 } Ok.

[kamailio/kamailio] free_fixup functions in cmd_export_t are not called (Issue #3814)

by Xenofon Karamanos

### Description It seems that the fixup_free_* functions are not getting called when used with: ``` static cmd_export_t cmds[] = { {"acc_log_request", (cmd_function)w_acc_log_request, 1, acc_fixup, free_acc_fixup, ANY_ROUTE}, // ... {0, 0, 0, 0, 0, 0} }; static int free_acc_fixup(void **param, int param_no) { LM_CRIT("acc free fixup = %d\n", param_no); if(*param) { pkg_free(*param); *param = 0; } return 0; } ``` Nothing is getting logged from the function. Is this expected not to print in free_fixup due to the destruction of kamailio and the logging is not reliable? I also used gdb and added some breakpoints in `fixup` and `free_fixup` functions in some other modules (file_out) and the breakpoint was only found in `fixup` but not in `free_fixup`. When is the `free_fixup` supposed to be called, at kamailio destruction or after fixing it and before the main loop starts?  ### Troubleshooting #### Reproduction  Use any module that has a custom (maybe also provided from core) `free_fixup` function, and monitor if `free_fixup` is called using debug mode. #### Log Messages  ``` Apr 15 15:52:03 app01 kamailio[812169]: INFO: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7fcdcab18010, 56) called from file_out: file_out.c: fo_fixup_str_index(287) Apr 15 15:52:03 app01 kamailio[812169]: INFO: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7fcdcab18010, 64) returns address 0x7fcdcacc4280 frag. 0x7fcdcacc4240 (size=64) on 1 -th hit``` `0x7fcdcacc4240` fragment is not found anywhere in the logs reported that it was freed unlike other malloced resources. ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.9.0-dev0 (x86_64/linux) 8bc64a flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 8bc64a compiled on 15:32:09 Apr 15 2024 with gcc 10.5.0 ``` * **Operating System**:  ``` No LSB modules are available.

[kamailio/kamailio] Module dispatcher: ds_is_active() return incorrect. (Issue #4001)

by Minh Vũ

#### Kamailo 5.8 ### Description I use ```ds_is_active function()``` in ```dispatcher``` module. ``` $var(sip_url) = $sht(conf_fs=>$var(conf_id)); # sip:192.168.1.44:5060 if(ds_is_active("1", "$var(sip_url)")){ #### is allways run } ``` or ```ds_is_active("1", $var(sip_url))``` #### Debugging Data When I check dispatcher: ``` "DEST": { "URI": "sip:192.168.1.44:5060", "FLAGS": "IP", "PRIORITY": 0, "ATTRS": { "BODY": "rweight=50;weight=50;cc=1", "DUID": null, "MAXLOAD": 0, "WEIGHT": 50, "RWEIGHT": 50, "SOCKET": null, "SOCKNAME": null, "OBPROXY": null } } ``` Why is the flag set to ```IP```, but ```ds_is_active()``` returns true? -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4001 You are receiving this because you are subscribed to this thread.
