FOSDEM Voip Dinner 2025

by Torrey Searle

Hello all, As in previous years, I'm organising the VoIP dinner for FOSDEM (1 Feb @ 19:00) However unlike previous years (since the restaurant got upset about splitting the bill 30 ways). I will ask everyone to order their meal and pay in advance. (and I will pay the bill to the restaurant with my card) If you are wanting to attend the dinner please fill out the following form and follow the instructions for payment. https://form.jotform.com/250012543310033 Contact details are also in the form if you want to reach out to me with any further questions. Kind regards Torrey

[kamailio/kamailio] auto_bind_ipv6 prevents startup when kamailio pid is 1 ( docker ) (Issue #4094)

by Matteo

### Description When starting Kam inside a docker container and the `auto_bind_ipv6` option is enabled, kam fails to start, see below for error logs. Instead, inside the very same container, by executing it from a shell, it works. The difference is that starting from the entrypoint kam has pid 1, while starting from a shell as a different pid. ### Troubleshooting #### Reproduction Start kamailio inside a docker container,with network=host and the `auto_bind_ipv6` option enabled. #### Log Messages  ``` 2025-01-02T15:58:29.655278523Z 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: lo Fam: 2 Flg: 10049 Adr: 127.0.0.1 2025-01-02T15:58:29.655282371Z 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: eth0 Fam: 2 Flg: 11043 Adr: 188.34.182.80 2025-01-02T15:58:29.655286664Z 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: docker0 Fam: 2 Flg: 1003 Adr: 172.17.0.1 2025-01-02T15:58:29.655290864Z 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: br-1653739d678f Fam: 2 Flg: 11043 Adr: 172.18.0.1 2025-01-02T15:58:29.655295002Z 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: br-kamnet Fam: 2 Flg: 11043 Adr: 172.23.42.1 2025-01-02T15:58:29.655299578Z 0(1) ERROR: <core> [core/socket_info.c:1349]: nl_bound_sock(): could not bind NETLINK sock to sockaddr_nl 2025-01-02T15:58:29.655303602Z 0(1) ERROR: <core> [core/socket_info.c:1666]: add_interfaces_via_netlink(): Could not get network interface list 2025-01-02T15:58:29.655482917Z 0(1) ERROR: <core> [core/socket_info.c:1789]: fix_hostname(): could not resolve 'matteo-ord-devel' 2025-01-02T15:58:29.655515080Z 0(1) ERROR: <core> [core/socket_info.c:2392]: fix_all_socket_lists(): fix_socket_list udp failed 2025-01-02T15:58:29.655519918Z failed to initialize list addresses ``` ### Possible Solutions I think that it boils down to the function [nl_bound_sock](https://github.com/kamailio/kamailio/blob/master/src/core/so… function, which sets the netlink struct Port ID with `getpid()` ( https://github.com/kamailio/kamailio/blob/master/src/core/socket_info.c#L13… ). For some reason this does not work when kam is forking from pid 1. According to [man 7 netlink](https://man7.org/linux/man-pages/man7/netlink.7.html) should be safe to set that pid to 0, and let the kernel assign one, since if assigned from the process, it must guarantee that is unique if when multiple sockets are requested. I've tried to set that port id to `0` and works correctly: ```diff diff --git a/src/core/socket_info.c b/src/core/socket_info.c index 2557a83b1e..662a3741c2 100644 --- a/src/core/socket_info.c +++ b/src/core/socket_info.c @@ -1343,7 +1343,7 @@ static int nl_bound_sock(void) bzero(&la, sizeof(la)); la.nl_family = AF_NETLINK; la.nl_pad = 0; - la.nl_pid = getpid(); + la.nl_pid = 0; la.nl_groups = 0; if(bind(sock, (struct sockaddr *)&la, sizeof(la)) < 0) { LM_ERR("could not bind NETLINK sock to sockaddr_nl\n"); ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` 5.8.4 * **Operating System**:  Docker container based on ubuntu noble. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4094 You are receiving this because you are subscribed to this thread.

[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.
