Hello, I am considering to release Kamailio v5.6.6 (out of branch 5.6) later this week (likely on Wednesday, July 3, 2024). If anyone is aware of issues not yet on the bug tracker, report them there asap in order to have a better chance to be fixed. This is going to be the last release out of branch 5.6 to mark the end of official/packaging maintenance.

[kamailio/kamailio] Dialog DMQ sync: Timer needs fixing, firing on wrong node! (Issue #3656)

by Benoît Panizzon

Situation: Two Kamailio nodes syncing dialog profiles via DMQ Observation: When a dialog timeout is encountered, about half of the time, the timeout is triggered on the peer node not handling the dialog preventing the call to be correctly terminated and also leaving entries in the dialog database which never get deleted. https://kamailio.org/docs/modules/5.7.x/modules/dialog.html#dialog.p.enable… Makes clear, that only the node which is handling the dialog in question, can make changes not related to the dialog profiles. So when a dialog times out, it is this node which has to trigger the timeout, not any other one. When looking at the source code, it is clear, that the 'lifetime' is transmitted via DMQ dialog message to the peer nodes, which in turn arm a timer. So it is obvious, this time will trigger, sometimes before the instance handling the dialog itself triggers that timer. With some assistance of @oej I found a way to alter the JSON payload to extend the lifetime on the peer nodes: ``` route[DMQ_CAPTURE] { if(is_method("KDMQ")) { if(has_body("application/json") && $fU == 'dialog') { if (jansson_get("lifetime", $rb, "$var(lifetime)")) { $var(new_lifetime) = $var(lifetime) + 60; # Add 60 seconds on DMQ peer to make sure it expires AFTER main node. $var(newrb) = $rb; jansson_set("integer", "lifetime", $var(new_lifetime), "$var(newrb)"); set_body("$var(newrb)","application/json"); msg_apply_changes(); } } dmq_handle_message(); exit; } } ``` Testing with this config fixed the issue of the timeout firing on a peer node instead of the node handling the dialog. Issue is present in 5.5, 5.6 and after looking at the code, I assume also on 5.7 -Benoît -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3656 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] rtpengine: show errno and error string in more places where it is useful (PR #3899)

by Oded Arbel

#### Pre-Submission Checklist - [x] Commit message has the format required by CONTRIBUTING guide - [x] Commits are split per component (core, individual modules, libs, utils, ...) - [x] Each component has a single commit (if not, squash them into one commit) - [x] 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: - [x] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #### Description In `send_rtpp_command()` if socket operations fail with an error other than `EINTR` or `ENOBUFS`, the actual error is not reported - we just get a generic "Can't send command to/read reply from RTPEngine". Other places in the module report `errno` and `strerror(errno)` using the log format "`(%s:%d)`" so added that to the error log. Also fixed `bind_force_send_ip()` error log to use the same semantic as the other places.

[kamailio/kamailio] ims_registrar_pcscf,ims_qos: support for trusting bottom via (PR #3901)

The current code is using a mix of that, plus using Contact and Via headers, with arguable potential security issues. This patch adds a new parameter to `ims_registrar_pcscf` and `ims_qos` modules, allowing for an optional outsource of the IPsec functionality to another element, which is also in charge of checking/enforcing correct UE Via header. The existing code is allowed to work as before, with the default value of the flag being towards that. List of functional changes: - `ims_qos` - added `trust_bottom_via` parameter - used it on `w_rx_aar_register()` - `ims_registrar_pcscf` - added `trust_bottom_via` parameter - used it on `update_contacts()`, `save_pending()`, `check_contact()`, `getContactP()`, `check_service_routes()`, `enforce_service_routes()` - made `ims_ipsec_pcscf` dependency optional, with checks when used - skipped checks of `port-uc` in `checkcontact()` if the `ims_ipsec_pcscf` module was not loaded - added `ignore_contact_rxproto_check` parameter - IMS devices open IPsec Security Associations just between IPs and ports, with both UDP and TCP protocols allowed. The default then was set here to always ignore protocol checks. Before, the `ignore_contact_rxport_check` was used to skip this and still make it work, but that seemed like a typo/mistake with hidden effects. List of indirect changes: - `core/ut.h`: added a `str2ushort()` macro, since code was using some dangerous casting and macros with a larger type - `ims_registrar_pcscf`: added `Route` headers in `SUBSCRIBE` to `reginfo`, with values from `Service-Route`s, as per 3GPP specs. - `ims_usrloc_pcscf`: small log fixes You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/3901 -- Commit Summary -- * core: added str2ushort() to avoid some questionable casting in ims_qos * lib/ims: fixed a typo in a log message * ims_usrloc_pcscf: small log fixes * ims_qos: added trust_bottom_via parameter * ims_registrar_pcscf: added trust_bottom_via parameter, added ignore_contact_rxproto_check, fixes for logging, fixes for SUBSCRIBE to reginfo for including Service-Route, allow use without ims_ipsec_pcscf -- File Changes -- M src/core/ut.h (8) M src/lib/ims/ims_getters.c (2) M src/modules/ims_qos/doc/ims_qos.xml (6) M src/modules/ims_qos/doc/ims_qos_admin.xml (41) M src/modules/ims_qos/ims_qos_mod.c (27) M src/modules/ims_qos/rx_aar.h (4) M src/modules/ims_qos/rx_authdata.h (2) M src/modules/ims_qos/rx_avp.c (2) M src/modules/ims_registrar_pcscf/doc/ims_registrar_pcscf.xml (6) M src/modules/ims_registrar_pcscf/doc/ims_registrar_pcscf_admin.xml (73) M src/modules/ims_registrar_pcscf/ims_registrar_pcscf_mod.c (26) M src/modules/ims_registrar_pcscf/notify.c (2) M src/modules/ims_registrar_pcscf/save.c (80) M src/modules/ims_registrar_pcscf/service_routes.c (136) M src/modules/ims_registrar_pcscf/subscribe.c (74) M src/modules/ims_registrar_pcscf/subscribe.h (4) M src/modules/ims_usrloc_pcscf/udomain.c (4) -- Patch Links -- https://github.com/kamailio/kamailio/pull/3901.patch https://github.com/kamailio/kamailio/pull/3901.diff -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/pull/3901 You are receiving this because you are subscribed to this thread.
