[kamailio/kamailio] CDP module fails to properly send DPA upon DPR (Issue #3092)
by Atanas Bakalov 23 Nov '23

23 Nov '23

### Description It seems there is a problem with the sending of the DPA from the cdp module to the diameter peer. When we receive the DPR the `Snd_DPA()` and `I_Disc()` are executed from peerstatemachine.c (I_Open/I_Rcv_DPR branch). Since the socket is closed from `I_Disc()` the `select()` in the `receive_loop` exits with a failure and the send pipe (which holds the DPA) is never sent to the other side. ### Troubleshooting #### Reproduction ``` 1. Send DPR from diameter peer to Kamailio 2. DPA is never received on the other end ``` #### Log Messages ``` Apr 24, 2022 @ 20:43:58.854 +0200 pcscf 44(138) DEBUG: cdp [peerstatemachine.c:89]: sm_process(): sm_process(): Peer chordlet State

[kamailio/kamailio] Kafka: Wrong format on RPC responses (Issue #2991)
by Olle E. Johansson 23 Nov '23

23 Nov '23

The kafka module use printf-like message to print statistics in rpc_kafka_stats() which doesn't follow the style for other RPC commands that produce data structures parsable as data, like when using jsonrpc. ``` if (rpc->rpl_printf(ctx, "Total messages: %" PRIu64 " Errors: %" PRIu64, msg_total, msg_error) < 0) { rpc->fault(ctx, 500, "Internal error showing total statistics"); return; } ``` I think this is a bug, but easy to fix. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2991 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] CNXCC doesn't update values on Redis DB (Issue #2948)
by Simone de Blasiis 23 Nov '23

23 Nov '23

### Description We are trying to use CNXCC in order to monitor credit usage but it doesn't appear to be working. The cnxcc_set_max_credit call appears to be working partially as we can see that a new key is created in the Redis DB but with all the values set to 0. The values that we set in the cnxcc_set_max_credit are hardcoded but it doesn't seem to work. This is an example of what we find in the Redis DB: ``` 1637599472.872820 [1 127.0.0.1:53578] "HEXISTS" "cnxcc:money:pippo@dom.domain.it" "concurrent_calls" 1637599472.872942 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.873043 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "concurrent_calls" "0" 1637599472.873159 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.873292 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "consumed_amount" "0.000000" 1637599472.873404 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.873515 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "ended_calls_consumed_amount" "0.000000" 1637599472.873634 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.873752 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "max_amount" "0.000000" 1637599472.873875 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.874000 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "number_of_calls" "0" 1637599472.874115 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.874269 [1 127.0.0.1:53578] "HSET" "cnxcc:money:pippo@dom.domain.it" "type" "1" 1637599472.874381 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.874481 [1 127.0.0.1:53578] "SREM" "cnxcc:kill_list:money" "\"pippo(a)dom.domain.it\"" 1637599472.874585 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" 1637599472.874747 [1 127.0.0.1:53578] "HINCRBY" "cnxcc:money:pippo@dom.domain.it" "number_of_calls" "1" 1637599472.874845 [1 127.0.0.1:53578] "EXPIRE" "cnxcc:money:pippo@dom.domain.it" "70" ``` This issue is identical to the one described in #1387 ### Troubleshooting #### Reproduction We are running Kamailio 5.5 from the official repos on Debian 10. All the modules are installed through the repo. This is the config that we are currently using to set the values for the modules. We also tried setting the values straight into the function bypassing the variables but the result is the same. ``` $dlg_var(credit) = "50.0"; $var(connect_cost) = "5.0"; $var(cost_per_sec) = "1.0"; $var(i_pulse) = 1; $var(f_pulse) = 1; xlog("$dlg_var(label) $var(credit) $var(connect_cost) "); if (cnxcc_set_max_credit("$dlg_var(label)", "$dlg_var(credit)", "$var(connect_cost)", "$var(cost_per_sec)", "$var(i_pulse) ", "$var(f_pulse)") < 0) { xlog("Failed to setup credit control"); sl_send_reply("503", "Internal Server Error"); exit; } ``` #### Log Messages The call to cnxcc_set_max_credit() doesn't throw any errors and returns 1 as if everything worked correctly ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.5.2 (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, 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 8.3.0 ``` * **Operating System**: ``` No LSB modules are available.

somehow pointed me to the payload - so I tried to change the AMQP-payload in the config to a minimalistic custom JSON document. With this config, the crash does no longer occur: ``` diff /usr/local/etc/kamailio/kamailio.cfg /usr/local/etc/kamailio/kamailio.cfg.sample 497,501d496 < loadmodule "kazoo.so" < modparam("kazoo", "amqp_connection", "amqp://guest:guest@guest@rabbitmqhost:5672") < modparam("kazoo", "node_hostname", "sipproxy.mydomain.com") < modparam("kazoo", "pua_mode", 0) < 523,533d517 < xlog("SCRIPT: Snipppet from kazoo_query-documentation:\n"); < #$var(amqp_payload_request) = "{'Event-Category' : 'call_event' , 'Event-Name' : 'query_user_channels_req', 'Realm' : '" + $fd + "', 'Username' : '" + $fU + "', 'Active-Only' : false }"; < kazoo_encode("$ci", "$var(callid_encoded)"); < $var(amqp_routing_key) = "call.status_req.$var(callid_encoded)"; < if(kazoo_query("callevt", $var(amqp_routing_key), "{\"blop\":\"example\"}", "$var(amqp_result)")) { < kazoo_json("$var(amqp_result)", "Channels[0].switch_url", "$du"); < if($du != $null) { < xlog("L_INFO", "$ci|log|user channels found redirecting call to $du"); < return; < } < } ``` So, some issue in the exmaple's payload causes the crash. One the one hand, I think an example from the documentation should somehow work, on the other hand I think that an error in a JSON-payload is not indended to crash kamailio anyway.  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` kamailio -v version: kamailio 5.6.0-dev2 (x86_64/linux) 63a349 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: 63a349 compiled on 16:12:36 Nov 6 2021 with gcc 9.3.0 ``` * **Operating System**:  ``` uname -a Linux hostname 5.11.0-38-generic #42~20.04.1-Ubuntu SMP Tue Sep 28 20:41:07 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux lsb_release -a No LSB modules are available.

[kamailio/kamailio] Recrod-Route header without socket port for calls to WebRTC clients (#2850)
by sergey-safarov 23 Nov '23

23 Nov '23

### Description When call routed to WebRTC client and used `record_route()`, then Record-Router header does not contain port of socket where WebRTC client connected. When used `tcp_reuse_port = yes`, then `ACK` cannot be delivered to WebRTC client (#2849). #### Reproduction I prepared a minimal config that allows reproduce the issue and attached a log file for the test call. ``` # use compact IPv6 addresses ipv6_hex_style = "c" enable_tls=1 tcp_accept_no_cl=yes ######## Kamailio control connector module ######## loadmodule "ctl.so" modparam("ctl", "binrpc_buffer_size", 4096) loadmodule "pv.so" loadmodule "sl.so" loadmodule "xlog.so" loadmodule "tls.so" loadmodule "nathelper.so" modparam("tls", "config", "/etc/kamailio/tls.cfg") loadmodule "xhttp.so" loadmodule "websocket.so" loadmodule "ipops.so" loadmodule "siputils.so" loadmodule "rr.so" loadmodule "debugger.so" modparam("debugger", "cfgtrace", 1) modparam("debugger", "log_level_name", "exec") log_stderror=yes # IPv4 listeners listen=udp:eth0:5060 listen=tcp:eth0:5060 listen=tls:eth0:5061 listen=tls:eth0:7001 # IPv6 listeners listen=udp:[2600:1f18:578:5701::7e]:5060 listen=tcp:[2600:1f18:578:5701::7e]:5060 listen=tls:[2600:1f18:578:5701::7e]:5061 listen=tls:[2600:1f18:578:5701::7e]:7001 request_route { if (!has_totag()) { record_route(); } if (is_ipv4($si)) { route(WEBRTC_PBX); } else { route(PBX_WEBRTC); } } route[WEBRTC_PBX] { set_contact_alias(); $du = "sip:[2600:1f14:6d8:5409::100]:5080;transport=tcp"; forward(); exit; } route[PBX_WEBRTC] { handle_ruri_alias(); forward(); exit; } event_route[xhttp:request] { if (!($hdr(Upgrade)=~"websocket" && $hdr(Connection)=~"Upgrade" && $rm=~"GET")) { $var(status_code) = 400; $var(reason_phrase) = "Bad Request"; xhttp_reply("$var(status_code)", "$var(reason_phrase)", "text/plain", "$var(reason_phrase)"); exit; } if (!ws_handle_handshake()) { $var(status_code) = 400; $var(reason_phrase) = "Bad Request"; xhttp_reply("$var(status_code)", "$var(reason_phrase)", "text/plain", "$var(reason_phrase)"); exit; } exit; } ``` #### Log Messages For Call-ID: a8c7450a-131c-11ec-9546-a727fc4b684e ``` INVITE sips:safarov@df7jal23ls0d.invalid;rtcweb-breaker=no;transport=wss SIP/2.0^M Record-Route: <sips:3.236.25.254;transport=ws;r2=on;lr;ftag=FNBFNvy0atDeK>^M Record-Route: <sips:[2600:1f18:578:5701::7e];transport=tcp;r2=on;lr;ftag=FNBFNvy0atDeK>^ ``` Client connected to socket `tls:3.236.25.254:7001` but using `record_route()` generated ``` Record-Route: <sips:3.236.25.254;transport=ws;r2=on;lr;ftag=FNBFNvy0atDeK> ``` Full logs at [kam.log](https://github.com/kamailio/kamailio/files/7148185/kam.log) ### Additional Information * **Kamailio Version** - output of `kamailio -v` used master branch with small customization, base commit c503d2bd31a580138a67f1d4a265ccde5791d271 * **Operating System**: aarch64 ``` [root@tmp kamailio]# cat /etc/os-release NAME="CentOS Linux" VERSION="8" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="8" PLATFORM_ID="platform:el8" PRETTY_NAME="CentOS Linux 8" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:8" HOME_URL="https://centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-8" CENTOS_MANTISBT_PROJECT_VERSION="8" ``` -- You are receiving this because you are subscribed to this thread.
