[kamailio/kamailio] dialog: set context iuid for CANCEL requests (PR #3096)

set context iuid for CANCEL requests to let isflagset function return the right value in case a dialog flag was previously set on the call   #### Pre-Submission Checklist    - [ ] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [x] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  Using kamailio 5.4 version, we have seen that dlg_isflagset is not detecting a dialog flag set in the request route for the initial INVITE, when a CANCEL request arrives. We have applied this change to set the dialog context unique ide for this request. Since it's done on dlg_onreply, dlg_onroute and dlg_ontimeout functions. This way, dlg_get_by_iuid(&dctx->iuid) in the function ki_dlg_isflagset is not NULL and dialog flags are detected. Is this change correct? Or can it generate any kind of issues? thanks a lot and regards David You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/3096 -- Commit Summary -- * dialog: set context iuid for CANCEL requests to let isflagset function return the right value in case a dialog flag was previously set on the call -- File Changes -- M src/modules/dialog/dlg_handlers.c (3) -- Patch Links -- https://github.com/kamailio/kamailio/pull/3096.patch https://github.com/kamailio/kamailio/pull/3096.diff -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/pull/3096 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Path MTU discovery for IPv6 (PR #3141)

See Issue #3119 for my discovery / learning path. In short, unconnected UDP sockets do not learn Path MTU problems, so a message dropped once will be dropped again on resend. Using `IPV6_PMTUDISC_WANT`, any knowledge in the kernel can be used to fragment the message at sending time, as intended for IPv6. These patches actually correct two IPv6-related things in the `core/udp_server.c`, 1. Benefit from any kernel knowledge about Path MTU for IPv6 2. The same option to learn from UDP_ERRORS is now available for IPv6 Do note that the last has not been implemented for IPv4 or IPv6. It is more useful for IPv6, allowing instant "tm" resends for Path MTU, but not "sl" I think. I cannot do that work, but this brings IPv6 to the same level as IPv4. ``` commit 0f90cff05c1a448eb2f85f83b4c087ab32ede11 Author: Rick van Rein <rick(a)openfortress.nl> Date: Sat Jun 11 10:57:32 2022 +0000 core: Issue 3119. Handling ICMPv6 Packet too Big - This was only defined for IPv4 under flag UDP_ERRORS - IPv6 has no toggle DF to clear for en-route fragmentation - Kamailio currently does not collect with recvmsg(...,MSG_ERRQUEUE) - The benefits of adding that can be instant resends for "tm" messages - Note that "sl" messages will have been forgotten at this point commit 6b404b5f9807174177bee36eaf3543be0794f55e Author: Rick van Rein <rick(a)openfortress.nl> Date: Sat Jun 11 10:44:27 2022 +0000 core: Issue #3119. Path MTU kernel info for IPv6 - For IPv4, DF is an option; for IPv6 it is always active - This makes pmtu_discover an IPv4-only option - This means that we should set IPV6_MTU_DISCOVER to IPV6_PMTUDISC_WANT - Unconnected UDP sockets can now learn from ICMPv6 "Packet too Big" - As a result, hitting a Path MTU upper bound is a learning process - This should stop consistent SIP packet drops due to Path MTU ``` You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/3141 -- Commit Summary -- * core: Issue #3119.

[kamailio/kamailio] [stirshaken] add identity header in reply messages or to a separate variable (#2770)
by sergei lavrov 14 Aug '22

14 Aug '22

### Description I'm unable to add the generated `Identity` value to reply message when `kamailio` acts as a redirect server and replies with `302 Moved Temporarily` instead of relaying `INVITE`. This code doesn't work, i.e. no `Identity` header in `302 Moved Temporarily` message: ``` if (stirshaken_add_identity($var(x5u), $var(attest), $var(origtn_val), $var(desttn_val), $var(origid)) == 1) { append_branch("sip:$rU@127.0.0.1:6060"); sl_send_reply("302", "Moved Temporarily"); exit; } ``` ### Expected behavior It would be nice if the `stirshaken_add_identity_*` functions would add the generated `Identity` header to the reply messages too, or store the generated `Identity` header in a separate variable, like `$identity`, for the future processing. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] secfilter: Wrong format on RPC response data (Issue #2992)
by Olle E. Johansson 12 Aug '22

12 Aug '22

secfilter RPC functions to get statistics use a console format to printing data, suitable for **kamcmd** but not for any RPC method. This should be converted to a machine-parsable data structure (much like dispatcher, usrloc and htable data dumps). -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2992 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Add 5.6 branch packages for Ubuntu 22.04 (Issue #3147)
by compuwizz 09 Aug '22

09 Aug '22

Is it possible to add the 5.6 branch deb/ubuntu packages to https://deb.kamailio.org/ for Ubuntu 22.04? I see Ubuntu 22.04 native repos have kamailio 5.5 in them but I'd like to use 5.6. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3147 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Location for git submodules in the source tree (Issue #3164)
by Daniel-Constantin Mierla 08 Jul '22

08 Jul '22

With the introduction of an external project reference via git submodule by `tls_wolfssl`, I am opening this to discuss where it would be the _best_ place for them. Now it is in the folder of the tls_wolfssl module, but I noticed that many projects have a dedicated folder like `vendor` (or `extern`, `import`), and I would somehow that approach more because it is easier to locate the external code and figure out its implications in licensing, dependencies, etc ... Moreover, it can happen that many modules would need to use that external project/repo. For example, now crypto uses libssl, but for someone that wants to get rid of it and use only libwolfssl may contribute an alternative of that module. Then two modules would need same external repo and having it inside another module would not be straightforward to manage. Given the above, I would suggest to place them in a folder like `misc/vendor` or similar inside the `misc/` directory, not to get back into growing the root folder. I would like to keep `src/` folder only for Kamailio specific code. If someone has other suggestions, propose them in comments and let's try to get to a decision soon. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3164 You are receiving this because you are subscribed to this thread.
