lists.osmocom.org migrated to mailman3
by Harald Welte 03 Jan '22

03 Jan '22

Dear Osmocom community, today our mailing list server lists.osmocom.org has finally been migrated from mailman2-on-freebsd to mailman3-on-linux. This also included a variety of changes to DNS. I'll spare you the details, but everything _should_ be up and running now. * The List-Id headers should not have changed. * all list subscriptions + user accounts have been converted. * old 'static html' archives are still available (read only) at URLs like https://lists.osmocom.org/pipermail/baseband-devel/ * old List URLs like https://lists.osmocom.org/mailman/listinfo/baseband-devel are redirected to their respective modern counterparts In case you notice any mailing list related problem, please don't hesitate to contact me.

RLC/MAC layer in real networks is always used in acknowledged/reliable mode, and LLC is always only used in unreliable (UI) mode. The reason for this is that TCP cannot deal with the enormous packet loss that GPRS or similar radio links pose. If TCP would be exposed to the real packet loss, it would stall way too much. So my rationale was to use the same while creating osmo-sgsn. We use LLC in UI mode. Or are we talking about something completely else?

if we should use more C++ features (I am not talking STL, operator overloading)? Any opinions? holger PS: I think we should find a more nice solution to extern "C".. I spent various minutes trying to figure out which parts of the pcu have C linkage and which C++.. For things from libosmocore it is obvious.. but then we have the vty_info... -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

bug fixes. Ideally I'd love to see Andreas developing them on top of the current 'master' and submitting them to the mailing list as soon as he push them. This way Ivan (and everyone else) would be able to review them and merge as soon as possible. I hate the situation when fixes are stored in a private branch and are not merged into mainline.

TTCN-3 tests for MME
by Mirko Kovacevic 29 Oct '21

29 Oct '21

Hi, Osmonians, I don't know where to write for MME TTCN-3, so I chose to write to it closet relative - SGSN. I was trying to do slight modification to TTCN-3 code, modifing S1AP_Templates.ttcn. I embedded enodeb name for all tests with new protoc-IE = id-eNBname : ################################## template (value) S1AP_PDU ts_S1AP_SetupReq(template (value) Global_ENB_ID p_global_ENB_ID, template (value) SupportedTAs p_supportedTAs, template (value) PagingDRX p_pagingDRXs) := { initiatingMessage := { procedureCode := id_S1Setup, criticality := reject, value_ := { S1SetupRequest := { protocolIEs := { { id := S1AP_Constants.id_Global_ENB_ID, criticality := ignore, value_ := { Global_ENB_ID := p_global_ENB_ID } }, { id := S1AP_Constants.id_SupportedTAs, criticality := reject, value_ := {SupportedTAs := p_supportedTAs} }, { id := S1AP_Constants.id_eNBname,//id-eNBname criticality := ignore, value_ := {ENBname := "OsmoEnodeb"} } /* HACK: work around nextepc bug , { id := S1AP_Constants.id_pagingDRX, criticality := ignore, value_ := {PagingDRX := p_pagingDRXs} } */ } } } } } ######################## Code compiles, but PDU is not encoded well. I attached Wireshark preview. Can you help me with this issue ? -- Puno pozdrava, Mirko Kovacevic

Osmocom redmine upgrade / Let me know if something broke
by Harald Welte 27 Oct '21

27 Oct '21

Dear Osmocom community, today we finally upgraded our redmine installation from the unmaintained 3.4.x to the latest 4.2.3. The upgrade had been overdue for years, but today we (actually, Kevin) finally managed to find out how to make the openid_provider plugin to work with modern rails 5.x. In any case, I'm just informing you in case there is some unexpected fallout. I've verified that at least the following appears working: * logging into redmine * openid authentication from gerrit.osmocom.org (also after logout/relogin) * graphviz rendering * mscgen rendering There could however still be unexpected problems, particularly in features such as * e-mail notifications from redmine * updating redmine issues via e-mail * git integration ("Closes: OS#xxxx") If you run into any troubles, pleas report to https://osmocom.org/projects/osmocom-servers or if that also fails, feel free to send e-mails.
