[kamailio/kamailio] Adding listen flag to ignore matches in grep_sock_info when an IP is not active locally (Issue #2984)
by rhys-hanrahan 12 Jan '22

12 Jan '22

### Description As per my thread on sr-users: **Active/active keepalived - Kamailio includes non-local virtual IP in "myself" which breaks DMQ call routing**, I am seeing issues due to the behavior of `check_self` and more specifically `grep_sock_info`. I have attached a patch with a proposed new feature that would allow changing this behaviour slightly, although I've avoided changing any default behaviour. I have a setup with keepalived in active/active mode, with two virtual IPs. The goal is that each VIP is active only one one node at a time, but in the event of a failure, both VIPs would become active on one node. The issue I am facing is that in order for this to work, I need to have both nodes listen on both virtual IPs at all times, but this means that both nodes always consider traffic to those IPs local to themselves, even when that is not the case. This breaks many things, basically anything with `uri == myself`. But even internally in Kamailio itself, this is causing problems. For example: PATH support is broken and this is not easily fixed in the config because `lookup()` is actually using `check_self()` internally. I am sure there are many other features which will not work right in the above scenario, and this is why I'm proposing a change in the code itself, instead of just trying to solve it in the config. I've attached a patch file with my proposed change and would appreciate any feedback as to my overall approach. If this seems OK then I will put together a pull request for your review. Thanks! ### Expected behavior Kamailio should detect what IP addresses are currently active locally on it's system before considering the socket a match. If the IP is not currently there, it should ignore the match as if it is not currently listening on this IP (because it really is not!) #### Actual observed behavior Right now, Kamailio looks blindly at all "listen" sockets and looks for a match, regardless of if that IP is currently active locally or not, and this causes the false results of `check_self` ### Possible Solutions As mentioned, I'm attaching a patch showing my overall approach. Basically: * I am using pre-existing functions as much as possible for best compatibility e.g. IPv6 and IPv4. * I use `dns_resolvehost()` which seems to have a caching function built-in and so I am hoping the performance impact of my change would be negligible. * My code only makes a change _if_ the virtual flag is set, and if not, existing behaviour is kept so as to avoid any breaking changes.

[kamailio/kamailio] integer overflow in 'core.shmmem' output (#2824)
by Julius Flohr 12 Jan '22

12 Jan '22

Hi, we are using kamailio with more than 4GB of shared memory. When using 'core.shmem' we are expierencing an integer overflow in the output. The issue can be found here: https://github.com/kamailio/kamailio/blob/1ddc27f199061025a6a43da3e8a1388fc… I currently don't have the time to setup a build environment so I can't fix it myself. cheers. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] module_db_mysql: Allow '@' in username/password for db_url URIs (#1346)

Database as a Service providers like e.g. Microsoft Azure use these in usernames by default. The existing URI parser always treated the '@' as a separator between username:password and host:port/db parts of the URI. The parser now checks how many '@' characters are present in the URI and only treats the last occurence as separator for the host:port/db part.

[kamailio/kamailio] erlang: getting null value in erl_xbuff in response of erl_rpc request (#2069)
by vipulpatel310 11 Jan '22

11 Jan '22

### Description **I did:** I have installed kamailio 5.2.4 in ubuntu system and configured kamailio script to connect with erlang node also it sends rpc request to erlang node and get response which I have printed in a logs. ... $erl_list(L) = "two"; $erl_list(L) = "one"; xlog("L_ALERT","Before RPC: $erl_list(args=>format)\n"); erl_rpc("erlang", "list_to_tuple", "$erl_list(args)", "$erl_xbuff(repl)"); xlogl("L_ALERT","type(reply): $erl_xbuff(repl=>type), format(repl): $erl_xbuff(repl=>format)\n"); ... **Expected to happen:** Response should be get from erlang node against RPC request and it should be store in erl_xbuff. And it should be print logs like: ALERT: <script>: 501:type(reply): tuple, format(repl): {"one", "two"} **Actually happened:** Response is getting properly. but the problem is to store data into xbuff so it print logs like: ALERT: <script>: 501:type(reply): <null>, format(repl): <null> ### Troubleshooting I have check with older version 4.3.0 and it works fine. getting this problem after 5.2.0 version So, I have compare 5.2.0 and 4.3.0 version code. I found one change in pv_xbuff.c file which is creating a problem when I revert the change then it works fine. #### Reproduction It will be reproducible everytime. Just sends rpc request and get the value in xbuff. check xbuff value #### Log Messages Problem logs: ``` ALERT: <script>: Before RPC: [["one", "two"]] WARNING: <core> [core/mem/q_malloc.c:480]: qm_free(): WARNING: free(0) called from erlang: pv_xbuff.c: xavp_decode(1209) ALERT: <script>: 501:type(reply): <null>, format(repl): <null> ``` logs after change: ``` ALERT: <script>: Before RPC: [["one", "two"]] WARNING: <core> [core/mem/q_malloc.c:480]: qm_free(): WARNING: free(0) called from erlang: pv_xbuff.c: xavp_decode(1209) ALERT: <script>: 501:type(reply): tuple, format(repl): {"one", "two"} ``` ### Possible Solutions revert the 6542a367638ec5f8a2b62994f8c309e7a2533962 commit.

[kamailio/kamailio] kamailio can't support send Rx_AAR for origin call (#1793)
by lsm808 11 Jan '22

11 Jan '22

Hi All, When kamailio(kamailio-5.0) receive 200 OK message, we need to send Rx_AAR for origin and term call. Rx_AAR("MT_aar_reply", "origin","",2); for origin call Rx_AAR("MT_aar_reply", "term","",2); for term call. But from source code ims_qos_mod.c, we see lots of part like below to not support for a request. Even we comments them, there are still lots of issues, could we support the scenarios like below: when kamailio receive 200 OK, we can send Rx_AAR for term and origin call. //We don't ever do AAR on request for calling scenario... if (msg->first_line.type != SIP_REPLY) { // Added by vlv // LM_DBG("Can't do AAR for call session in request\n"); // return result; } -- You are receiving this because you are subscribed to this thread.
