[kamailio/kamailio] callout from event_route [tm:local-response] only occurs once (Issue #3064)
by dpaape 03 Feb '24

03 Feb '24

version: kamailio 5.5.2 (arm6/linux) 55e232 raspberry pi 3b I initially stated that I was running on 5.5.3 but I was mistaken. However I checked the 5.5.3 source and it appears to be the same. I think that there is a bug in the tm module with respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a static variable called '_tm_local_response_set_lookup'. This variable is initialized at load time to zero. It is checked in the '_reply_light()' routine and will initiate a local callback from the config script if "armed". The problem as I see it is that if the callback is readied, the variable is set to one. But it is never reset. So the observed behavior is as follows. A REGISTER is received and the request_route arms the callback. The REGISTER requires an authorization (local database sqlite). After the 401 is sent back, the callback via the event route is called as expected. All good except that the event route script fragment is never executed again after the first call... ever, even if it's a new REGISTER request. I would think that somewhere in the tm module, the variable should be reset to zero so that subsequent transactions can initiate the event route again. Or maybe the variable ought to live somewhere in the transaction cell??? . . . t_on_reply ("MY_FRAG"); t_on_failure ("MY_FRAG"); . . . event_route [tm:local-response] { xlog ("L_NOTICE", IN tm:local-response\n"); my_function(); } . . . So 'my_function()' is only called once. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3064 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] when enabled haproxy protocol required use kamailio server haproxy IP (Issue #3666)
by sergey-safarov 03 Feb '24

03 Feb '24

### Description I have enabled `tcp_accept_haproxy=yes`, inbound TCP connection received on IPv6 kamailio socket but client real IP is IPv4. When kamailio add `Record-Route` header then added IPv6 header and not added IPv4. Example ``` INVITE sip:xxxx@example.com SIP/2.0 Record-Route: <sip:9sovfn2oP7ozLQID7BkFxBNt/CfE+wc=@[2600::6]:5060;r2=on;lr=on> Record-Route: <sip:9sovfn2oP7ozLQID7BkFxBNt/CfE+wc=@[2600::6]:5060;transport=tcp;r2=on;lr=on> ``` From client perspective Kamailio make protocol conversion from the IPv4 to IPv6, and expected to see IPv4 in the IPv4 address in the received 'Record-Route' headers to use in the future requests. Because client receiving IPv6 only and client does not have IPv6 address, then `ACK` message cannot be send to Kamailio. ### Expected behavior Kamailio will use Kamailio server load balancer address to generate `Record-Route` headers. Load balancer IP address can be received from the HAPROXY protocol. #### Actual observed behavior Kamailio use listeneer socket IP to generate `Record-Route` headers. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3666 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] TLS related crash in Kamailio 5.7.2 (double free) (Issue #3635)

[kamailio/kamailio] dialog: failover database loading behaviour in shared DB scenario, expiration of dialogs (#2080)
by Henning Westerholt 20 Jan '24

20 Jan '24

The dialog module will expire dialogs that don't actually belong to the particular proxy. Scenario: 2 proxies on 5.2.4 with a loadbalancer in front. Call was routed over proxy1, dialog timeout on proxy2 was shorter (to make it easier to reproduce it). The results: * Dialog synchronized with DMQ: proxy 2 would timeout the dialog * Dialog entry synchronized to proxy2 DB and proxy2 restarted: Proxy2 would timeout the dialog * Dialog entry synchronized to proxy2 DB and proxy2 not restarted: Proxy2 would _not_ timeout the dialog (I’ve tried both db_mode 1 and 2) So the proxy2 would load the dialog into memory and then later expire it. So timeout routes, send_bye on timeout would not work correctly. One idea to solve this would be to check e.g. over the existing socket data if the dialog belongs to this proxy and skip loading it in this case. This could be also made configurable e.g. with a module parameter. Any comments? Better ideas how to solve it? -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] ndb_redis doesn't use AUTH on a slave server in redis cluster. (Issue #3654)
by Dries De Gendt 19 Jan '24

19 Jan '24

### Description & troubleshooting I have defined a redis cluster as followed. The cluster consists of 3 masters (port 6379) and 3 slaves (port 6380). The password is identical on all nodes through redis option 'requirepass'. ``` modparam("ndb_redis", "server", "name=sbcredis;addr=SBCMASTERREDISIP;port=6379;db=0;pass=REDACTED") modparam("ndb_redis", "server", "name=sbcredis;addr=PRIVATEIP;port=6380;db=0;pass=REDACTED") modparam("ndb_redis", "server", "name=sbcredis;addr=ASTP5IP;port=6380;db=0;pass=REDACTED") modparam("ndb_redis", "server", "name=sbcredis;addr=ASTP6IP;port=6379;db=0;pass=REDACTED") modparam("ndb_redis", "server", "name=sbcredis;addr=ASTP3IP;port=6380;db=0;pass=REDACTED") modparam("ndb_redis", "server", "name=sbcredis;addr=ASTP4IP;port=6379;db=0;pass=REDACTED") modparam("ndb_redis", "cluster", 1) modparam("ndb_redis", "allow_dynamic_nodes", 1) modparam("ndb_redis", "debug", 3) ``` When executing the redis_cmd command, most of the times an expected warning is shown due to another server providing the requested slot: `"(error) MOVED ... 192.168.136.241:6380"` Notice that I've enabled "allow_dynamic_nodes" to make sure there is an automated connection attempt to the indicated server. However, it appears that sometimes a "NOAUTH Authentication required." error is thrown when there is a redirection to a slave server serving that slot. I can authenticate succesfull on the redis-cli when using the identical password though. Also note that when a redis master is queried, the redis_cmd is successful. #### Reproduction Each simple redis command that needs authentication (GET, SET, ...) `redis_cmd("sbcredis", "SET TESTKEY TESTVALUE", "r");` #### Log Messages ``` ndb_redis [redis_client.c:1089]: redisc_exec(): Redis error:NOAUTH Authentication required. ``` ### Possible Solutions None for now except disabling the password on all nodes. ### Additional Information ``` kamailio 5.7.2 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3654 You are receiving this because you are subscribed to this thread.
