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?
Regards,
Harald

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

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?
Regards,
Harald

* With multiple TBF assignment the tbf_by_tlli will return a list
anyway.
* For the multiple RACH cases we could it probably handle it more
nicely.
E.g. avoid this:
<0005> bts.cpp:1035 Got RACH from TLLI=0xcf7611f6 while TBF(TFI=0 TLLI=0xcf7611f6 DIR=DL) still exists. Killing pending DL TBF
<0002> bts.cpp:359 Got IMM.ASS confirm, but TLLI=cf7611f6 does not exit

if we should use more C++ features (I am not talking STL, operator
overloading)?
Any opinions?

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...

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.
