[kamailio/kamailio] uri_restore_rcv_alias() tried twice for local request (#2014)
by Alex Hermann 18 Nov '20

18 Nov '20

### Description While debugging an issue with locally generated in-dialog requests I stumbled upon some weirdness with the alias functionality from the nathelper module. The dialog modules tries to handle an alias parameter when sending an in-dialog request by calling ```uri_restore_rcv_alias()``` in the function ```build_dlg_t()```. A few instructions later, the same is attempted by the tm module in the function ```req_within()```. It seems to me that the attempt by the dialog module is redundant and can be removed. And while at it, IMHO it should be removed from the tm module too. This is functionality introduced by the nathelper module. Nowhere in the documentation it is mentioned there is some automatic handling of the alias parameter. If handling is needed for local requests, the script writer can call ```handle_uri_alias()``` from within local_route. If the functionality has to stay, may I suggest that the code in the nathelper module makes use of the ```uri_restore_rcv_alias()``` function instead of having its own duplicate implementation. Less maintenance, easier debugging. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] 100% CPU usage after NTP date update (#2046)
by Benjamin Marty 18 Nov '20

#### Reproduction Install newest Kamailio 5.2. Change date e.g. 2 Years into the future. (Make sure you have no daemon running which prohibits those operations): ``` sudo date -s "2014-12-25 $(date +%H:%M:%S)" ``` ``` sudo date -s "2016-12-25 $(date +%H:%M:%S)" ``` Kamailio now uses the whole CPU to do stuff: ``` top - 08:10:35 up 14 days, 1:29, 2 users, load average: 3.77, 1.83, 1.05 Tasks: 212 total, 11 running, 201 sleeping, 0 stopped, 0 zombie %Cpu(s): 95.9 us, 1.5 sy, 2.2 ni, 0.0 id, 0.0 wa, 0.0 hi, 0.4 si, 0.0 st MiB Mem : 926.1 total, 116.3 free, 382.5 used, 427.3 buff/cache MiB Swap: 100.0 total, 40.4 free, 59.6 used. 423.4 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13264 root 20 0 89720 3944 2676 R 44.9 0.4 0:05.15 kamailio 13266 root 20 0 89720 4000 2736 R 37.3 0.4 0:04.63 kamailio 13267 root 20 0 89720 4912 3488 R 36.0 0.5 0:04.37 kamailio 13270 root 20 0 89720 4540 3240 R 36.0 0.5 0:05.85 kamailio 13269 root 20 0 89720 4000 2736 R 34.7 0.4 0:04.81 kamailio 13265 root 20 0 89720 3944 2680 R 34.4 0.4 0:04.61 kamailio 13261 root 20 0 89720 3952 2676 R 32.2 0.4 0:04.44 kamailio 13262 root 20 0 89720 3944 2676 R 31.8 0.4 0:04.72 kamailio 13256 root 20 0 89720 4752 3540 R 30.3 0.5 0:07.04 kamailio 13268 root 20 0 89720 4000 2736 R 30.3 0.4 0:04.49 kamailio 18021 root 20 0 40116 11884 5728 D 13.7 1.3 0:01.11 apt-get ``` There are multiple mailing list entries regarding this issue: https://lists.kamailio.org/pipermail/sr-users/2015-October/090465.html https://lists.kamailio.org/pipermail/sr-users/2015-November/090487.html https://lists.kamailio.org/pipermail/sr-users/2019-June/105967.html https://lists.kamailio.org/pipermail/sr-users/2019-August/106428.html I was able to get rid of the issue with uncommenting the mentioned part of the code.

[kamailio/kamailio] RTPengine PV varaibles missing the leg wise vallues for media stats attributes like jitter (mos_average_jitter_A_pv), mos (mos_average_A_pv), packetloss (mos_average_packetloss_A_pv ) etc (#2340)

### Description Extract media stats per leg from RTPengine but in spite of labels being present in RTPengine logs the values are not extracted in their respective PV's Note : the overall average, max and min values appear fine ### Troubleshooting Opened Kamailio in debug mode and saw that labels are being set , yet appearing as null Snipets ``` tagsd8:91e08b04d3:tag8:91e08b045:label6:caller7:createdi1590686836e16:in dialogue with13:tKtpK3BHjFavK6:mediasld5:indexi1e4:type5:audio8:protocol8:RTP/AVPF7 .. looking for label '<null>' ``` Full logs below in the "Log Messages" section #### Reproduction Using Lua on Kamailio v5.2.1 1. Add labels in RTPengine offer , ensuring the traffic is AVPF ``` local rtpengine_codecs_flag = " codec-strip-all codec-offer-PCMA codec-offer-pcma " local rtpengine_offer_flag = "ICE=remove RTP/AVPF full-rtcp-attribute direction=external direction=external replace-origin replace-session-connection record-call=yes " .. rtpengine_codecs_flag .. " label=caller " local rtpengine_answer_flag = "ICE=remove RTP/AVPF full-rtcp-attribute direction=external direction=external replace-origin replace-session-connection record-call=yes label=callee " ``` 2. set the mos label ``` KSR.pv.sets("$avp(mos_A_label)", "caller"); ``` 3. Make call and do RTPengine offer and answer like usual ``` KSR.rtpengine.rtpengine_offer(rtpengine_offer_flag) ... KSR.rtpengine.rtpengine_answer(rtpengine_answer_flag) ``` 3. On BYE , do rtpengihne delete ``` KSR.rtpengine.rtpengine_delete0() ``` 4. gather PV values for legs ``` KSR.log("info", "mos_A_label " .. KSR.pv.getvn("$avp(mos_A_label)", 1) ..

[kamailio/kamailio] Extend rtpengine hashing algorithms (#1986)

#### 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 - [ ] 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 - [ ] Tested changes locally - [ ] Related to issue #1911 #### Description  The goal was to have a different, more complex hashing algorithm that would offer a better distribution among nodes. We've seen in production that the current algorithm does not perform well under heavy load therefore we decided to add SHA1 hashing. After running performance tests we've decided that we need a cryptographic function in order to have the best results mostly when the callids have small entropy. In order to add SHA1, a new API was added in crypto module exporting a function applying SHA1 to a string. The API was used in rtpengine module over the callid. After this operation the hash was calculated as before except for applying 0xFF mask over the hash as it was done before, which restrains the power of this algorithm.
