[OpenSIPS-Users] Segfault using TLS

[Mark Farmer]

Hi everyone

I am trying to setup TLS to talk to MS Teams but I am getting a segfault
when I try to start OpenSIPS.

CRITICAL:core:sig_usr: segfault in attendant (starter) process!

The server is Ubuntu 20.04.1
OpenSIPS 3.1.0

>From the log:

INFO:tls_mgm:mod_init: initializing TLS management
DBG:core:__search_avp_map: looking for [tls_sip_dom] avp  - found -1

My TLS config:

#### TLS_MGM Module
loadmodule "tls_mgm.so"
modparam("tls_mgm", "server_domain", "dom1")
modparam("tls_mgm", "match_ip_address", "[dom1]xxx.xxx.xxx.xxx:5061")
modparam("tls_mgm", "match_sip_domain","[dom1]my.domain.com")
modparam("tls_mgm", "client_sip_domain_avp", "tls_sip_dom")
modparam("tls_mgm", "certificate",
"[dom1]/usr/local/etc/opensips/tls/mycert.pem")
modparam("tls_mgm", "private_key",
"[dom1]/usr/local/etc/opensips/tls/mykey.key")
modparam("tls_mgm", "ca_list",
"[dom1]/usr/local/etc/opensips/tls/calist.pem")
modparam("tls_mgm", "ca_dir", "[dom1]/usr/local/etc/opensips/certs/CA")
modparam("tls_mgm", "tls_method", "[dom1]TLSv23")

#### PROTO_TLS Module
loadmodule "proto_tls.so"
modparam("proto_tls", "tls_max_msg_chunks", 8)
modparam("proto_tls", "trace_on", 1)
modparam("proto_tls", "trace_destination", "sngdst")
modparam("proto_tls", "tls_handshake_timeout", 300)

Is anyone able to help with this please?

Best regards
Mark.
