[kamailio/kamailio] Debian package build fails for Kamailio 5.7.4 (Issue #3722)
by Alexander Bakker 15 Jul '24

15 Jul '24

### Description The Debian package build fails for Kamailio 5.7.4 because it can't find static libssl. This happens because ``LIBSSL_STATIC_SRCPATH`` is set to the wrong location in the rules file. ### Troubleshooting #### Reproduction 1. Run ``ln -s pkg/kamailio/deb/bookworm debian`` 2. Run ``make deb`` #### Output ``` gcc -shared -g -m64 -Wl,-O2 -Wl,-E -Wl,-z,relro -pthread -rdynamic "-ldl" -Wl,-Bsymbolic-functions tls_bio.o tls_cfg.o tls_config.o tls_ct_wrq.o tls_domain.o tls_dump_vf.o tls_init.o tls_locking.o tls_map.o tls_rand.o tls_rpc.o tls_select.o tls_server.o tls_util.o tls_verify.o tlsa_mod.o -lm /usr/lib64/libssl.a /usr/lib64/libcrypto.a -o tlsa.so /usr/bin/ld: cannot find /usr/lib64/libssl.a: No such file or directory /usr/bin/ld: cannot find /usr/lib64/libcrypto.a: No such file or directory collect2: error: ld returned 1 exit status make[5]: *** [../../Makefile.rules:191: tlsa.so] Error 1 ``` ### Possible Solutions An extremely hacky workaround is to patch the rules file to point ``LIBSSL_STATIC_SRCPATH`` to the right location: ``` sed -i -e "/LIBSSL_STATIC_SRCPATH/a export\\ LIBSSL_STATIC_SRCPATH=\\/usr\\/lib\\/$(uname -m)-linux-gnu" pkg/kamailio/deb/bookworm/rules ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.7.4 (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_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**: ``` Distributor ID: Debian Description: Debian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm ``` ``` Linux 6.5.0-14-generic #14-Ubuntu SMP PREEMPT_DYNAMIC Tue Nov 14 14:59:49 UTC 2023 x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3722 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] No CDR is written on failover (Issue #3254)
by Earn330 15 Jul '24

15 Jul '24

Hi, I think there is an issue with writing CDRs on failover scenarios. I have two servers with Kamailio. Both server running Debian 11 (bulleye) and latest Kamailio 5.6.1 from git. I'm using DMQ to sync dialogs and htable between these servers, so both servers have the same knowledge of dialog state. Both Kamailio uses nobind option, so I can switch a VIP from one server to the other one. This is managed with keepalived. Switching the VIP from one server the other one works fine an while a call is running I can switch the VIP. I can see that the BYE Message is handled OK after I made a switch. I can see that acc is triggered but what is missing is acc_cdr in this case. I'm using htable to fill all necessary variables to complete the CDR an I can see that all values are synced correctly. The acc_cdr is created fine if there is no failover so i think it can't be an configuration issue. Both server holds the same Kamailio configuration except the IP. `version: kamailio 5.6.1 (x86_64/linux) bfc5c2-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, TLS_PTHREAD_MUTEX_SHARED 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: bfc5c2 -dirty compiled with gcc 10.2.1` `root@voip-lab-proxy01:~# lsb_release -a No LSB modules are available.

[kamailio/kamailio] performance regression related to new TCP connection tracking feature with a high number of connections (Issue #3759)
by Henning Westerholt 05 Jul '24

05 Jul '24

### Description On systems with a high number of TCP sessions there can be a significant performance regression observed, probably related to the newly added TCP connection tracking feature. ### Troubleshooting #### Reproduction No special configuration is necessary, just install the latest 5.7.x release, e.g. 5.7.3 on a production system with a lot of clients connected over TCP or TLS. You need to have a large number of clients connected to be able to observe the regression. For a high number of connections (e.g. more then 20.000 up to 30.000 connections) the Kamailio servers uses about 30% to 50% more CPU as with the old version. #### Debugging Data Two graphs were attached to this issue. The first shows the CPU load before (less load) and after the upgrade (increased load). The second is a flamegraph that shows that over 80% of the CPU time is spent in the newly added function tcp_connection_limit_srcip(). <img width="372" alt="cpu-load-before-after" src="https://github.com/kamailio/kamailio/assets/6481937/ec92c41b-25e2-4847-a4bc…"> ![flamegraph](https://github.com/kamailio/kamailio/assets/6481937/5c2e3982-2d5b-4acd-a774-bad8fa64bd0a) Most of the CPU time is spend in the TCP main process, as expected. #### Log Messages No special log messages could be observed. #### SIP Traffic ### Possible Solutions The TCP limit feature should probably be optimized to not cause such a large performance regression. It should be also possible to deactivate it completly and therefore getting a comparable performance as before the feature addition. ### Additional Information Kamailio 5.7.3 and probably also git master version. * **Operating System**: Debian 11, Debian 12 -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3759 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] tcpops module event_route[tcp:closed] route block $conid is null (Issue #3767)

### Description During the process of using version 5.7.4 of Kamailio, I found that the $conid cannot be correctly obtained in the TCP: closed routing block of the TCP module event_route.

[kamailio/kamailio] secsipid method to only validate signature without checking the rest of the header (Issue #3784)
by Ben Kaufman 05 Jul '24

05 Jul '24

### Description Currently secsipid has a method to sign arbitrary (json) data (`secsipid_sign`), however it has no converse method to check the signature. Currently, an attempt to check a `div` signature for example will yield a `-303` error (`SIPHdrInfo`). Rather than trying to have full parsing for every possible type of Identity header (which are likely to increase in variety), it would be good to simply check "is this signature valid by trusted key", possibly validating the `iat` timestamp as well, but without any other opinions on the header values. ### Expected behavior A feature to check only the signature of an identity header. #### Actual observed behavior Currently the `secsipid_check_` family of functions fails for non- `shaken` passport types. #### Debugging Data The following DIV identity header was generated by secsipid's `secsipid_sign()` function, so it should be possible to reverse this to validate the signature: ``` Identity: eyJhbGciOiJFUzI1NiIsInBwdCI6ImRpdiIsInR5cCI6InBhc3Nwb3J0IiwieDV1IjoiaHR0cHM6Ly9kLm10c2VjLm1lL2QzYTkvQmZUeGJVTlozS1FMLnBlbSJ9.eyJkZXN0Ijp7InRuIjpbIjE2MTI1NTU0MzIxIl19LCJpYXQiOiIxNzEwMTY5MzQ1Iiwib3JpZyI6eyJ0biI6IjE1NTU3MzU5MzA5In0sImRpdiI6eyJ0biI6IjE5NTI1NTU5ODc2In19.-0QF6-u6zgAQNoAhdiETuhAu7FuRDzxmFch_cTdhcbeWvUZ60NQXxdPM-JucpOtFaEdn9wnFreAZ_6vZoc_Phg;info=<https://d.mtsec.me/d3a9/BfTxbUNZ3KQL.pem>;alg=ES256;ppt=div ``` ### Possible Solutions Because it's fairly straight forward to investigate the JWT, it's not necessary to try to account for every possible passport type, etc. The act of validating the signature is the complicated part, so a function that does only that would be convenient. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.7.4 (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_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**: Currently alpine linux 3.19 in a docker container, but it should be pretty reproducible everywhere. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3784 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio became unresponsive during runtime (#2380)
by ObakeFilter 27 Jun '24

27 Jun '24

### Description Hi, I ran into an issue where the Kamailio service seemingly froze (didn't crash, but failed to receive and deliver calls) while running, I went through the logs a little bit, and saw the same log pattern (pasted below) recouring every few months or so, on an older installation (5.2.0). Usually, it ended up automatically restarting the service. But not this time, I had to reload it manually to make the service work again. Is this a known issue? How can I make sure that the service will be able to restart the next time it happens?

[kamailio/kamailio] Kamailio 5.6 (and 5.7) core dumps. (Issue #3725)
by Mattis Lind 19 Jun '24

19 Jun '24

### Description We have a quite basic scenario which sends a SIP MESSAGE and then receives SIP MESSAGE back. It also sets up two voice calls using SIP INVITE. It is only this specific scenario that is causing the core dump. Some time the core dump occur just a few seconds after the call/message scenario, but occasionally it takes up to 50 minutes. We have been using the uac module for sending SIP MESSAGE in several other scenarios without experiencing a crash. We always see the same lines in the log just prior to the core dump: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 49 We are using Kamailio 5.6 retrieved from the kamailio repository: http://deb.kamailio.org/kamailio56. We are running Kamailio in a Docker container which runs on "5.10.0-25-cloud-amd64 #1 SMP Debian 5.10.191-1 (2023-08-16) x86_64 GNU/Linux" We have also tried Kamailio 5.7 from the same repo which crashes in exactly the same way. ### Troubleshooting #### Reproduction We have troubles to consistently reproduce it and it only happen from time to time when running a specific scenario sending SIP MESSAGE using the uac module. It does not happen for every call of this call scenario. At one instance Kamailo crashed with just 15 seconds in-between during the call scenario. #### Debugging Data ``` # gdb /usr/sbin/kamailio /core GNU gdb (Debian 10.1-1.7) 10.1.90.20210103-git Copyright (C) 2021 Free Software Foundation, Inc.

[kamailio/kamailio] Kamailio ims_charging module Ro Interface User-Equipment-Info-Type AVP (Issue #3807)
by svinson1121 17 Jun '24

17 Jun '24

The Kamailio ims_charging module Ro interface is sending: AVP: User-Equipment-Info(458) -> AVP: User-Equipment-Info-Type(459) l=12 f=-M- val=MAC (1) see attached Ro.pcapng packet #7. but (unless I'm not understanding correctly) according to TS 132 299 this AVP should be of type IMEISV and not MAC for the Ro charging interface. also, the MAC is not encoded correctly. again, see the attached pcap at packet #7 from TS 132 299: "User-Equipment-Info-Type This field determines the type of the identifier. The used value is 0 for the international mobile equipment identifier and software version according to TS 23.003[224]. User-Equipment-Info-Value This field contains the user IMEI." "For PS charging, when the User-Equipment-Info-Type AVP (AVP code 459) is set to IMEISV (0), the value within the User-Equipment-Info-Value AVP (AVP code 460) is of type OctetString and shall be a UTF-8 encoded hexadecimal. The composition of the IMEISV follows the definition in TS 23.003 [224] . If only IMEI is received a filler ‘F’ is used to make it 16 digits." "For IMS charging, when the User-Equipment-Info-Type AVP (AVP code 459) is set to IMEISV (0), the value within the User-Equipment-Info-Value AVP (AVP code 460) is of type OctetString and shall be a UTF-8 encoded decimal. The composition of the IMEISV follows the definition in TS 23.003 [224]. If only IMEI is received the number of digits are truncated to 15." I have tested and found this in the following versions: version: kamailio 5.9.0-dev0 (x86_64/linux) 4fb8ac version: kamailio 5.3.2 (x86_64/linux) 87e8a1 Thank you so much for your help with this issue, [Ro.zip](https://github.com/kamailio/kamailio/files/14924042/Ro.zip) -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3807 You are receiving this because you are subscribed to this thread.
