[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] Topos does not unmask Refer-To header in in-dialog Refer request (Issue #4301)
by Matteo 03 Jul '25

xadhoom created an issue (kamailio/kamailio#4301)  ### Description When topos receives an in-dialog REFER, it correctly unmask everywhing as expected, but not the Refer-To header, which breaks transfers. ### Troubleshooting #### SIP Traffic  For example, this is the refer from a client: ``` REFER sip:atpsh-685d3cd2-69-2@172.23.42.1;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 172.23.42.1:23045;rport;branch=z9hG4bKlaklhcax Max-Forwards: 70 To: <sip:3338063766@example.voismart.com>;tag=Brcm20gBS5eZe From: "Joe" <sip:1001@example.voismart.com>;tag=xbdlk Call-ID: kpjiixyvombnlkw(a)fedora.fritz.box CSeq: 340 REFER Contact: <sip:1001@172.23.42.1:23045;transport=tcp> Refer-To: <sip:atpsh-685d3cd2-69-4@172.23.42.1;transport=tcp?Replaces=lmhzfrkbucirwbc%40fedora.fritz.box%3bto-tag%3dXDQD403r30jeS%3bfrom-tag%3dtwbnd> Referred-By: "Joe" <sip:1001@example.voismart.com> User-Agent: Twinkle/1.10.3 Content-Length: 0 ``` And this is what exits from topos proxy: ``` REFER sip:3338063766@172.23.42.211:5060;transport=udp SIP/2.0 Via: SIP/2.0/TCP 172.23.42.250;branch=z9hG4bK89f.32493a6f0ee894aad0bf66f581e5053a.0;i=3 Max-Forwards: 69 To: <sip:3338063766@example.voismart.com>;tag=Brcm20gBS5eZe From: "Joe" <sip:1001@example.voismart.com>;tag=xbdlk Call-ID: kpjiixyvombnlkw(a)fedora.fritz.box CSeq: 340 REFER Refer-To: <sip:atpsh-685d3cd2-69-4@172.23.42.1;transport=tcp?Replaces=lmhzfrkbucirwbc%40fedora.fritz.box%3bto-tag%3dXDQD403r30jeS%3bfrom-tag%3dtwbnd> Referred-By: "Joe" <sip:1001@example.voismart.com> User-Agent: Twinkle/1.10.3 Content-Length: 0 Route: <sip:172.23.42.3;transport=tcp;r2=on;lr=on;ftag=xbdlk;did=c84.2b02> Route: <sip:172.23.42.3;r2=on;lr=on;ftag=xbdlk;did=c84.2b02> Contact: <sip:btpsh-685d3cd2-69-2@172.23.42.250> ``` ### Possible Solutions Will try to find a solution, I see that in `tps_msg.c` `parse_refer_to.h` is included so perhaps there was some idea about it, but since I'm not an expert in kamailio internals may need some time. ### Additional Information v6.0.x and master -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4301 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] SIP Race condition when using dlg.end_dlg (Issue #4268)
by IgorG 02 Jul '25

02 Jul '25

IgorrG created an issue (kamailio/kamailio#4268) ### Description We use RPC dlg.end_dlg command to terminate dialog. In most cases it does operate properly and send BYE from kamailio to both sides of dialog (as show on screenshot). ![Image](https://github.com/user-attachments/assets/b49164a5-6442-4c66-bd4d-f5412678247f) We found that in some cases we have only first BYE sent to calling party. Second BYE never sent, when called party tries to terminate call by timeout it get responded with 481. ![Image](https://github.com/user-attachments/assets/10c90b4c-30a3-4123-8e2b-2ca64cdec3c3) ![Image](https://github.com/user-attachments/assets/f0facce8-3acf-4049-8a23-ad559874af7b) In logs we have such warning: мая 27 15:11:46 service-proxy.iqtek.ru kamailio[3518388]: 2(3518388) WARNING: {1 1 BYE 541d3f2c-43fd-43b6-af24-bad1fbf85eb6} dialog [dlg_handlers.c:1343]: dlg_onroute(): unable to find dialog for BYE with route param 'e1e.4f22' [3614:8948] and call-id '541d3f2c-43fd-43b6-af24-bad1fbf85eb6' We also found that in this case this warning shown in logs 0.04 seconds after kamailio receive 200ok. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # ./kamailio -V version: kamailio 5.8.6 (x86_64/linux) fb71db 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: fb71db compiled on 17:38:27 May 26 2025 with gcc 12.2.0 ``` * **Operating System**: ``` # lsb_release -a No LSB modules are available.
