RFC: updates to some core functions

by Daniel-Constantin Mierla

Hello, it was brought into discussions several times in the past about core functions not accepting variables in the parameters. I think it is time to update them during the 5.3 release development. For few of them, I added in the past some alternative function in the corex module (e.g., force_send_socket() in core and set_send_socket() in corex module). So, I see two options: 1) add a function with similar name in corex module and same behaviour like the one from core 2) remove the function export from the core and export one with the same name from the corex module First one will ensure that configs using the functions right now keep working without any update. The second one will be better in long term from the point of documentation (no duplicated docs), but there might be few cases that would require updates in the config -- iirc, there are some functions that can get special tokens in the parameters (like forward(uri:host, uri:port)), they will get an equivalent with variables, but old config will not be compatible. Obviously the reason for this email is to ask the developers and users what would be the preferred way from own point of view.

Re: [sr-dev] [kamailio/kamailio] dialog: safety checks for local cseq and contact vars (79946bb)

by Daniel-Constantin Mierla

Looks like a regression introduced with a patch that tried to avoid a crash -- I pushed another commit to skip the test on cseq when not taken from sip request. It is already in branch 5.2, can you test and see if all ok now? -- You are receiving this because you are subscribed to this thread.

by Cui Gang

Hi, My kamailio configuration file works well on the first release 5.2.0(535e13b). When I update kamailio server to the 5.2.0 branch last version, include this commit, dialog always ERROR like: ERROR: {...} dialog [dlg_handlers.c:212]: populate_leg_info(): empty CSeq number Why? And how can I fix it? Thanks! -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Proxy Protocol support (#1757)

by Sebastian Lauwers

### Description I would like to implement support for the Proxy Protocol as implemented by HAProxy and AWS ELBs. The main advantage this brings is better connection information, even behind multiple layers of NAT or LBs. This feature was already discussed a couple of years ago, and it appears the project was not against receiving a patch that adds support for this protocol: https://lists.kamailio.org/pipermail/sr-users/2016-June/093497.html For example, at the moment, my Kamailio deployment is "blind" when it comes to the origin of inbound TCP connections, because it is only able to report the internal IP address of our ELBs, rather than the actual IP address of the client, and IP address of the LB the connection was received on. Dixa is offering to sponsor work (my own hours) to implement this, and we would also be a production user of this feature. The Proxy Protocol is fairly well documented here: https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt As far as I know, AWS ELBs only implement version 1 of the protocol, but I believe there is value in implementing both (while we're at it), and the second version of the protocol is a lot easier to parse, anyway. I'm opening this feature request to a/ track progress, b/ discuss implementation details. -- You are receiving this because you are subscribed to this thread.
