RFC: migrating git.osmocom.org to gitea?
by Harald Welte 31 Mar '22

31 Mar '22

Hi all! [please follow-up-to the openbsc(a)lists.osmocom.org mailing list, if there is any discussion, we don't want to drag it over tons of mailing lists in parallel] Some weeks ago, I created https://osmocom.org/issues/5397 but it seems nobody noticed the ticket or had any comments to it. So let me post this as RFC here on the mailing list: In the past, we had a gitolite/gitosis setup, which was fine in the early days of git, but it means that people cannot easily create new repositories, see who has permissions, and we cannot delegate ownership. Even updating SSH keys requires manual interaction of a sysadmin like me. I would therefore suggest to migrate git.osmocom.org to gitea[1] This would allow the following features: * users can self-create any number of personal repositories (like gitlab/github) * we can create 'organizations' along the line of reasonably independent osmocom member projects like op25, who can then manage their own repos/permissions/... * gitea can link to redmine wiki and redmine issue trackers (rather than using its own built-in) For those repositories hosted in gerrit (mainly CNI), we would still keep git.osmocom.org a read-only mirror, like we do it right now. For those repositories not hosted in gerrit, users/projects could then accept merge requests in gitea. Coupling this with 3rd party authentication via github/gitlab/etc should make it easier for the occasional contributor to submit changes. There is a downside, of course; A lot of repo URLs have to change. Most of our current repositories are at git.osmocom.org/project.git while gitea follows a git.osmocom.org/organization/project.git scheme. I'm not sure there is any way to help to mitigate this... Any thoughts, comments?

OsmoDevCon 2022 ?
by Harald Welte 28 Mar '22

28 Mar '22

Dear fellow Osmocom developers, as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021, trying to compensate it at least to some extent with our OsmoDevCall every two weeks. The COVID-19 pandemic is far from over, and we don't know what the upcoming winter season will bring. Nevertheless, I think it would be a good idea to start a discussion of whether we should plan for an OsmoDevCon in 2022. I personally would say let's plan for the usual late April 2022 time frame, and if the pandemic situation deteriorates, we can still cancel it with something like one month lead time. I would also personally suggest to limit attendance to people who are fully vaccinated, and in addition do a self-test for all participants every morning. In terms of venue, we might also consider to move to a venue that allows better ventilation. Irrespective of the above we can also bring the air filters from the sysmocom office. So with that as an input statement, I would like to hear your opinion on the above proposals. Who would want to attend? Any complaints against the "vaccinated only plus daily self-tests in the morning" approach?

OsmocomBB releases
by Denis 'GNUtoo' Carikli 01 Feb '22

01 Feb '22

Hi, As I understand it is now possible to have a full software GSM stack in software[1], with the stock osmocomBB since trx_toolkit target was merged in OsmocomBB. Many network side components have releases[2] and several distributions already have part of the osmocom stack packaged[3][4]. To me having releases for osmocomBB as well also look interesting as we could then more easily make packages for it. It could then be used to test the other components of the stack either with hardware[5] or with pure software, or to easily install and keep up to date the tools (osmocon, osmoload, etc). Would the osmocomBB be interested in doing releases? Or is there something that is preventing that from happening (lack of interest?, lack of time/volunteers?, technical issues?). References: ----------- [1]https://osmocom.org/projects/baseband/wiki/FakeTRX [2]https://projects.osmocom.org/news/152 [3]https://packages.debian.org/search?keywords=osmo&searchon=names&suite=sta… [4]https://packages.gentoo.org/packages/net-libs/libosmocore [5]As I understand, it would require either a test license or a specific hardware setup with cables, attenuator(s) and a duplexer/circulator and to enable transmit support.

MT Call procedure
by Amirhosein naseri 18 Jan '22

18 Jan '22

Hi everyone. In MT Call flow must be as below MS BTS <- Setup Call Confirmed -> <- Assignment Command Assignment Completed -> Alerting -> Connect-> but in implemented code in mnccms.c file immediately after sending Call Confirmed message, Alerting message is sent from MS to BTS , and this lead to ignorance of Assignment Command from BTS. WHY the procedure implemented as this ???

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. Happy hacking, Harald -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
