The commit 0436af5abd8b73e breaks startup for jsonrpcs module. Logs: ``` Jul 5 10:04:41 kam01 kamailio[4951]: ERROR: jsonrpcs [jsonrpcs_sock.c:358]: jsonrpc_dgram_init_server(): failed to change the owner/group for /var/run/kamailio/kamailio_rpc.sock to 33.0;Operation not permitted[1] Jul 5 10:04:41 kam01 kamailio[4951]: CRITICAL: jsonrpcs [jsonrpcs_sock.c:423]: jsonrpc_dgram_init_socks(): initializing datagram server function returned error Jul 5 10:04:41 kam01 kamailio[4951]: ERROR: jsonrpcs [jsonrpcs_sock.c:246]: jsonrpc_dgram_mod_init(): init datagram sockets function failed Jul 5 10:04:41 kam01 kamailio[4951]: ERROR: jsonrpcs [jsonrpcs_mod.c:1150]: mod_init(): cannot initialize datagram transport Jul 5 10:04:41 kam01 kamailio[4951]: ERROR: <core> [core/sr_module.c:849]: init_mod(): Error while initializing module jsonrpcs (/usr/lib/x86_64-linux-gnu/kamailio/modules/jsonrpcs.so) ``` Relevant cfg: ``` loadmodule "jsonrpcs.so" modparam("jsonrpcs", "pretty_format", 1) modparam("jsonrpcs", "dgram_user", "www-data") modparam("jsonrpcs", "dgram_group", "root") modparam("jsonrpcs", "transport", 7) ``` Previously Kamailio was started as root, and then configured with -u $USER and -g $GROUP to drop privileges to the lower user/group. During startup Kamailio could create the socket with the correct permissions. The mentioned commit changes this to: start Kamailio directly as user Kamailio and group Kamailio, which don't have privileges create the sockets with the correct permissions. Not sure about the motivation about this change, so I don't want to simple revert it. Maybe @sergey-safarov or other developers can comment. -- You are receiving this because you are subscribed to this thread.
