[kamailio/kamailio] http_client leaks TLS shared memory (Issue #4231)
by Alexander Bakker 04 Jul '25

04 Jul '25

alexbakker created an issue (kamailio/kamailio#4231) ### Description Performing an HTTPS request using the ``http_client`` module results in a shared memory leak, seemingly related to TLS. ### Troubleshooting #### Reproduction Our use case for ``http_client`` is to update an htable with the latest banned IP's from APIBAN as described here: https://github.com/apiban/apiban?tab=readme-ov-file#integration-into-kamail…. Normally, we refresh the list of banned IP's once every 15 minutes, so the shared memory usage grows fairly slowly. The issue can be reproduced using the Kamailio configuration file below. To demonstrate the issue and make the shared memory usage grow faster, we set up a timer that calls ``http_client_query`` in a tight loop. To prevent unnecessary load on the APIBAN infrastructure, we request an example file from my personal server instead. ``` #!KAMAILIO debug=2 log_stderror=yes fork=yes enable_tls=1 loadmodule "tls.so" loadmodule "cfg_rpc.so" loadmodule "pv.so" loadmodule "xlog.so" loadmodule "ctl.so" loadmodule "rtimer.so" loadmodule "http_client.so" modparam("tls", "certificate", "") modparam("tls", "private_key", "") modparam("rtimer", "timer", "name=apiban;interval=100u;mode=1;") modparam("rtimer", "exec", "timer=apiban;route=APIBAN;") route[APIBAN] { xinfo("running apiban refresh\n"); http_client_query("https://alexbakker.me/u/7bvjn9jfas.txt", "$var(banned)"); } ``` Start Kamailio: ``` kamailio -f kamailio.cfg -DD ``` And then watch the shared memory usage grow rapidly: ``` watch -n1 -- kamcmd core.shmmem ``` #### Log Messages Eventually, Kamailio will run out of shared memory and print the following messages to the log: ``` 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: http_client [functions.c:471]: curL_request_url(): failed to perform curl (56) (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: http_client [functions.c:471]: curL_request_url(): failed to perform curl (56) (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: <core> [core/mem/q_malloc.c:758]: qm_realloc(): qm_realloc(0x7585c73c4000, 1024) called from tls: tls_init.c: ser_realloc(372), module: tls; qm_malloc() failed! 21(184184) INFO: <script>: running apiban refresh 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: <core> [core/mem/q_malloc.c:758]: qm_realloc(): qm_realloc(0x7585c73c4000, 1024) called from tls: tls_init.c: ser_realloc(372), module: tls; qm_malloc() failed! 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:463]: curL_request_url(): TLS CA certificate read error (url: https://alexbakker.me/u/7bvjn9jfas.txt) ``` ``mem_dump_shm`` reports a large list of TLS-related allocations.

[kamailio/kamailio] Duplicated presentities (and notifies) when usrloc and presence are replicated via dmq and pua_reginfo used (Issue #4252)
by Matteo 04 Jul '25

04 Jul '25

xadhoom created an issue (kamailio/kamailio#4252) ### Description A kamailio cluster which replicates presentities and usrloc via dmq may incur into duplicated presentities and notifications depending on config. The problematic setup, where each kamailio node has the following setup: - presence enabled with dmq - usrloc distributed with dmq - pua_reginfo used to publish reginfo to self Really is multiplicated by the numbers of nodes, so 4 nodes -> 4 times notifications and presentities. ### Troubleshooting The problem arise because pua_reginfo hooks to usrloc and every time a "save()" is done a publish is sent, which is by design. Then the handled publish generates a presentity which is replicated via dmq from presence module. Now, if also usrloc is replicated via DMQ, the handling of such message still trigger the hook, causing another publish with generates a different presentiy, since is new and the e-tag is different. This causes subscribers to receive <number of nodes> notifications on every status change. ### Possible Solutions The approach can be to optionally disable that hook (basically making pua_reginfo skipping publish) when handling a message via DMQ, so the usrloc replica is just saved. In other modules, like pua_dialoginfo or pua_usrloc this can be already done, since publishing can be controlled from script. ### Additional Information * **Kamailio Version** ``` 6.0.1 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4252 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio blocks in SSL_accept (Issue #4185)
by Mathias Schneuwly 04 Jul '25

04 Jul '25

schneuwlym created an issue (kamailio/kamailio#4185) ### Description This issue is a follow up of the discussion in the [mailing list](https://lists.kamailio.org/mailman3/hyperkitty/list/sr-users@lists.ka… We are using Kamailio 5.8.4 in a yocto scarthgap based image. We noticed on multiple nodes, that suddenly phones lost their registrations and the log showed messages like `send_fd(): sendmsg failed sending 55 on 52: Too many references: cannot splice (109)`. After debugging we guess that the `send_fd` messages are just a symptom, not the cause. Generating a backtrace using `kamctl trap` shows that all TCP receiver are waiting for a `pthread_rwlock_...` lock. Our deployments, where we randomly see the issue, are very small; 10-30 registrations. I've tested kamailio version 5.8.4, 5.8.5, 5.8.6 and 6.0.1 and I was able to reproduce the issue with all versions. I've also tested version 5.5.4, but with an older yocto (dunfell) which used openssl 1.1.1w, **which did not block!** Yocto Scarthgap uses OpenSSL 3.2.3 and we also updated to version 3.4.1, which didn't show any difference. ### Troubleshooting #### Reproduction Meanwhile we found a way to reproduce the issue within seconds. It requires a bit of brute force, but it locks kamailio reliable. We are generating 3 parallel SIP REGISTER streams with sipexer to 3 different accounts. Following an example of one stream: ``` watch -n 0.1 "./sipexer -register -vl 3 -co -com -ex 3600 -fu "2" -au "2" -ap "test" -tk <path to key>.key -tc <path to certificate>.cer -ti -sd -ru sip:<domain> -cu sip:2@<domain> tls:<fqdn>:5061;sleep 0.1;./sipexer -register -vl 3 -co -com -ex 0 -fu "2" -au "2" -ap "test" -tk <path to key>.key -tc <path to cert>.cer -ti -sd -ru sip:<domain> -cu sip:2@<domain> tls:<fqdn>:5061" ``` Our dialplan is quite complex, but I was also able to reproduce the issue with the default [dialplan](https://raw.githubusercontent.com/kamailio/kamailio/refs/heads/5.… with the following changes: ``` 169a170,171 > #!define WITH_TLS > 205a208,219 > alias=udp:<domain>:5060 > alias=udp:127.0.0.1:5060 > alias=udp:10.0.6.1:5060 > alias=tls:<domain> > alias=tls:10.0.6.1:5061 > alias=tls:10.165.42.76:5061 > alias=tls:<domain>:5061 > alias=udp:<domain> > listen=udp:127.0.0.1:5060 > listen=tls:10.0.6.1:5061 > listen=udp:10.0.6.1:5060 > listen=tls:10.165.42.76:5061 498c512 < modparam("tls", "config", "/usr/local/etc/kamailio/tls.cfg") --- > modparam("tls", "config", "/etc/kamailio/kamailio-tls.cfg") ``` ``` # cat /etc/kamailio/kamailio-tls.cfg [server:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = "<path to key>.key" certificate = "<path to cert>.crt" ca_list = "<path to ca>.pem" [client:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = "<path to key>.key" certificate = "<path to cert>.crt" ca_list = "<path to ca>.pem" ``` #### Debugging Data Following the backtrace of one tcp listener process.

[kamailio/kamailio] branch_failure_route does not handle reply while wt_timer period (Issue #4266)
by IgorG 01 Jul '25

01 Jul '25

IgorrG created an issue (kamailio/kamailio#4266) ### Description While implementing mid-register inspired by pull request (https://github.com/kamailio/kamailio/pull/3360) we found the case when it goes impossible to handle responses for registrar servers. In case some of registrars busy and respond with 401 after 200ok received - it is not possible using any routes and configuration options to handle responses received in branch transactions. According to documentation I think that setting wt_timer should allow to absorb and handle responses on failure-route while transaction kept in memory. In fact wt_timer does not affect handling responses in any way. ![Image](https://github.com/user-attachments/assets/14feb472-91ea-4028-8780-1fee1d4ee0e8) ### Troubleshooting To reproduce this case we have configured sipp to response instant with 200ok on registration request. #### Reproduction To reproduce issue SIPP could be setup as one of the dispatcher nodes with instant 200ok reply to register.

[kamailio/kamailio] [Websocket] websocket:closed sometimes is not fired (Issue #3950)
by Gustavo Almeida 27 Jun '25

27 Jun '25

### Description After carrying out some load tests using the `Websocket` module, I noticed that sometimes the `websocket:closed` event is not triggered. This problem seems to be particularly noticeable when the load is high and simultaneous. Example: 1000 records simultaneously. In the tests carried out, I realized that the number of times the event is not triggered is small, in the order of [1-10]/1000. I check that when I do a `ws.dump` I don't have any active connections, and I confirm that they are all effectively cleaned (`netstat -ano | grep 8061`). However, the event is not triggered for some connections. I can see this in the logs, and also when i display the content of an hash table, i'm dropping key inside `websocket:closed` event. ### Troubleshooting The troubleshooting was simplistic, i.e. I ran the same test n times, and validated that the event was triggered for all connections, the number of `ws` connections listed by `Kamailio`, and the open connections. #### Reproduction To reproduce, we can use any mechanism that emulates the use of the `Websocket` module. For example, I used the `sipexer` tool to create a `wss` connection with `Kamailio`, forcing simultaneous registrations. Example command: `sipexer -cb -mt register -ex 60 -au <user> -ap <pass> -fuser example -fd mydomain -wso https://10.0.0.12:10000 -ruri sip:kamailio -su wss://kamailio:8061` Kamailio TLS listener: `listen=tls:10.0.0.12:8061 advertise PUBLIC_IP` Websocket module: ``` loadmodule "websocket.so" tcp_accept_no_cl=yes ``` ``` event_route[websocket:closed] { xlog("L_NOTICE", "WebSocket connection closed $proto:$si:$sp\n"); <I also delete where a htable key> } ``` #### Debugging Data ``` [root@ ~]$ prcmd ws.dump { connections: { } info: { wscounter: 0 truncated: no } } [root@ ~]$ netstat -ano | grep 8061 tcp 0 0 10.0.0.12:8061 0.0.0.0:* LISTEN off (0.00/0/0) [root ~]$ prcmd htable.dump wsauth | grep "name" | wc -l 3 [root ~]$ cat /var/log/kamailio.log | grep "WebSocket connection closed" | wc -l 997 [root ~]$ cat /var/log/proxy-registrar/proxy-registrar.log | grep "ERR" | grep "WAR" | wc -l 0 ``` #### Log Messages Nothing relevant. #### SIP Traffic Nothing relevant here, the SIP Flow is OK. ### Additional Information ``` version: kamailio 5.6.4 (x86_64/linux) a004cf-dirty 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_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_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: a004cf -dirty compiled on 23:17:27 Jun 7 2024 with gcc 4.8.5 ``` * **Operating System**: ``` CentOS Linux release 7.9.2009 (Core) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3950 You are receiving this because you are subscribed to this thread.

QuincyGao created an issue (kamailio/kamailio#4190)  ### Description  I want to use opensips as SBC, When the agent registers to kamailio, the contact content is modified to the ip and port of kamailio, and then Register is forwarded to the agent. remove_hf("Contact") can't remove the whole Contact( field, vlue). here is my config: ``` route[REGISTRAR] { if (!is_method("REGISTER")) return; if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); #!ifdef WITH_NATSIPPING # do SIP NAT pinging setbflag(FLB_NATSIPPING); #!endif } fix_nated_contact(); if (!save("location","0x02")) { #if (!save("location")) { sl_reply_error(); } $fs="udp:172.16.4.111:5461"; $du="sip:172.16.4.114:5060"; remove_hf("Contact"); $var(contact) = "Contact: <sip:" +$fU+"@"+"172.16.4.111:5461>;expires=120\r\n" ; append_hf("$var(contact)"); route(RELAY); exit; } ``` here is the sip message: ``` 2025/03/26 16:36:07.706093 172.16.4.111:5461 -> 172.16.4.114:5060 REGISTER sip:172.16.4.111:5460 SIP/2.0 Via: SIP/2.0/UDP 172.16.4.111:5461;branch=z9hG4bKfc7e.d2df36f3b5681afeb71e442e645de38d.0 Via: SIP/2.0/UDP 172.16.80.3:49309;received=172.16.80.3;rport=49309;branch=z9hG4bKPj8ab8bd1d3c3a4c1bb0cd639540fa3183 Max-Forwards: 69 From: <sip:1008@172.16.4.111>;tag=95f7f5601f8b40458a1efe6923ab0a29 To: <sip:1008@172.16.4.111> Call-ID: f84b643f5d284d18a0d8175e1ef4d747 CSeq: 33264 REGISTER User-Agent: MicroSIP/3.21.6 sip:1008@172.16.80.3:49309;obExpires: 120 Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Content-Length: 0 Contact: <sip:1008@172.16.4.111:5461>;expires=120 ``` you can see the problem is that: `sip:1008@172.16.80.3:49309;obExpires: 120` , `sip:1008@172.16.80.3:49309` is the value of the Contact field after fix_nated_contact(). ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.5 (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: compiled on 11:27:01 Mar 21 2025 with gcc 4.8.5 ``` * **Operating System**:  ``` Centos7.9 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4190 You are receiving this because you are subscribed to this thread.
