[kamailio/kamailio] Undocumented TCP connection limit introduced in 5.7.3 must be configurable (Issue #3755)

by Sebastian Damm

### Description Scenario: Kamailio servers running behind a loadbalancer (AWS network loadbalancer in this case). This causes all packets to come from the same IP address in Kamailio's POV. The change https://github.com/kamailio/kamailio/commit/a902e4a032a85a7755de32eeadac800… introduced a connection limit per source IP address. This obviously conflicts with the setup mentioned above. We need up to 10000 client connections, which would seem to all come from the same IP address. Apart from this limit being introduced without a changelog entry (at least I didn't find one), I would expect it to be configurable. But from the commit it looks like it is a compile time option only.  #### Log Messages ``` Feb 15 09:24:00 sipproxy /usr/sbin/kamailio[174]: CRITICAL: <core> [core/tcp_main.c:4447]: handle_new_connect(): hit the limit of connections per source IP (100.68.15.172:33334) - rejecting Feb 15 09:24:01 sipproxy /usr/sbin/kamailio[174]: CRITICAL: <core> [core/tcp_main.c:4447]: handle_new_connect(): hit the limit of connections per source IP (100.68.15.172:1153) - rejecting Feb 15 09:24:01 sipproxy /usr/sbin/kamailio[174]: CRITICAL: <core> [core/tcp_main.c:4447]: handle_new_connect(): hit the limit of connections per source IP (100.68.15.172:59946) - rejecting ``` ### Additional Information Using the packages from the official Kamailio repository. * **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 11.4.0 ``` * **Operating System**:  ``` Ubuntu Jammy ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3755 You are receiving this because you are subscribed to this thread.

Missing values in xhttp_prom output

by Christian Berger

Hi, we at sipgate would like to know if there is a reason why the xhttp_prom module doesn't export statistics like stats.fetch all. We are missing the tls.info as well as pkg.stats values. Is there a reason for this? Are there any pointers on how we could implement it ourselves and provide patches?
