[kamailio/kamailio] lost: do not parse locationURI with indention spaces (#2569)

by sergey-safarov

### Description Examples of [RFC7840](https://tools.ietf.org/html/rfc7840#section-7) contains this response: ```xml <locationResponse xmlns="urn:ietf:params:xml:ns:geopriv:held"> <locationUriSet expires="2006-01-01T13:00:00.0Z"> <locationURI> https://ls.example.com:9768/357yc6s64ceyoiuy5ax3o </locationURI> <locationURI> sip:9769+357yc6s64ceyoiuy5ax3o@ls.example.com </locationURI> </locationUriSet> <routingInformation xmlns="urn:ietf:params:xml:ns:geopriv:held:ri"> <service serviceUri="urn:service:sos"> <dest>sip:112@example.com</dest> <dest>sips:112@example.com</dest> <dest>xmpp:112@example.com</dest> </service> </routingInformation> </locationResponse> ``` When the `lost` module receives such a response, then generate this message ``` http_client [functions.c:299]: curL_query_url(): Malformed URL used in http client (url: https://ls.example.com:9768/357yc6s64ceyoiuy5ax3o ) lost [functions.c:325]: lost_held_function(): dereferencing location failed: 3 ``` This error is fixed when if I strip spaces in a string of `locationURI` element. ### Troubleshooting #### Reproduction Send xml eample from RFC as responce for `lost_held_query` function call. ### Possible Solutions Strip leading and trailing spaces of `locationURI` element.

[kamailio/kamailio] dialog/dmq access dialog table by reference (#2570)

It was then leading to race conditions where the same entry could have its lock changed elsewhere and then a dead lock would occur. By checking the code in other places where the d_table is used, everywhere it is accessed by reference, this function was the only one not following this logic. Changes were done to have "entry" as a reference to d_table and not a copy.

[kamailio/kamailio] keep-alive refactoring: use case front-end proxy with backend registrar (#2565)

by sergey-safarov

### Description In my use case exists 1. pool of front-end proxies (all share some IPv4 address via AWS network load-balancer); 2. pool of backend registrars. I must: 1. send keepalive messages to endpoints when used INVITE, REGISTRAR, SUBSCRIBE methods via all possible transports (UDP/TSP/TLS/WS/WSS/SCTP) (like nat_keepalive function of nat_traversal module). Internally store record for this SIP URI with flag `ka_dynamic` and `Record-Route` headers from `180, 183, 200` responses as `Route`; 2. send keepalive messages on predefined SIP URI (like ka_add_destination of keepalive module). Internally store record for this SIP URI with flag `ka_static` and manually defined `Route` value; 3. when keepalive for cases above is failed, then added record into arrays: a. ka_invite_failed; b. ka_registrar_failed; c. ka_supscribe_failed; d. ka_invite_succcess; e. ka_registrar_success; f. ka_supscribe_success; 4. need to trigger `even route` function with initialized `xavp` params of a. of SIP URI endpoints; b. relevant array ID; c. dynamic or static flag of SIP URI record; d. `Record-Route` of SIP URI record; 5.If we have arrays for multiple arrays, then the `event router` function called multiple times. 6. the time period for `event route` calls must be configurable via module settings; 7. when executed `event route` I want to have abbility a. send a new registration message to the registrar node using saved `Route` header when OPTION is successful for the statically defined SIP URI; a. send registration expiration message to the registrar node from received `200` response; b. send the clear subscription message to the node from received `200` response; #### Actual observed behavior In current implementation `OPTIONS` keepalive messages send from different modules 1. usrloc; 2. keepalive; 3. nat_traversal; 4. nathelper All the above have limitations like: 1. no TCP/TLS/WS/WSS transport support (nat_traversal, nathelper); 2. no ability to define call `event-route` on failed (success) OPTIONS message (think all modules do not have such feature); 3. no ability to check response code before enabling keepalive (nat_traversal); 4. no ability to notify backend REGISTRAR/SUBSCRIPTION server (think all modules do not have such feature) about failed keepalive messages; #### What is expected >From my of view required: 1. some refactor of keepalive feature; 2. merge code from different modules into one and make other modules dependent; 3. implement the ability to notify backend REGISTRAR/SUBSCRIPTION servers of failed keepalive messages; 4. implement the ability to emulate registration when OPTION message success to SIP URI. Required on SBC to emulate customer PBX registration. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] DMQ workers stops processing msgs and consume all shmmem (#2547)

by pwakano

### Description Kamailio is configured to use the DMQ replication for dialog. When running a load test Kamailio DMQ workers eventually becomes unresponsive and stops processing DMQ messages. As a side effect the shm memory is fully consumed then SIP processing stops happening properly and everything else stops working due to that. ### Troubleshooting Investigation showed that the DMQ workers are locked in the dmq_send_all_dlgs. Debugging and studying the function it was identified that it is prone to data inconsistency because it uses a copy of the (d_table->entries)[index] and not a pointer to it. This gives a small window where a change in the d_table for that entry can occur and changing the lock information before the copy can actually get the lock making the process to get stuck in the lock get. There is a need for some expert to validate this conclusion. #### Reproduction Run a simple load test making calls at a rate of ~5 cps and keep around ~2000 calls connected all the time. A higher cps seems to make it easier to reproduce the problem. Adding network degradation to the environment makes the problem happens, but when running a tool such as SIPp for the load test, the retransmission can be forced by simply killing the SIPp instance receiving calls which will then force Kamailio to retransmit. #### Debugging Data ``` 7236 #
