Hi all,
Just wanted to share an issue and a quick workaround I found for it in case
anyone else has the same problem. I believe a cmd2 update is causing
pySim-shell to fail. After installing it on a fresh install of Ubuntu
Server 20.04 and getting the following error when I run "python3
pySim-shell -p0":
>Using PC/SC reader interface
>Autodetected card type: sysmoUSIM-SJS1
>AIDs on card:
> USIM: a0000000871002ffffffff8907090000

command_sets=basic_commands, >startup_script=script)
>TypeError: __init__() got an unexpected keyword argument 'use_ipython'
If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".

I means: is the interaction with mtp3 layer implemented (is sending sccp
data by mtp3 implemented by the library?)?
Also, what about the reception of data from mtp3 layer. is that implemented
in the sccp lib.
I am asking these questions because I see the code of mtp3 in the lib but no
significant call is present in the sccp part of the lib.
Thank you for your help.

A TS can be GSM_PCHAN_TCH_F_PDCH; those are the only ones for which we
send a PDCH ACT message.
We send a PDCH ACT message
- during init (CHANNEL OML's state changed to enabled -> send PDCH ACT),
- and upon channel release ack when pchan == GSM_PCHAN_TCH_F_PDCH.
So the question is, when we receive a channel release ack, could that be
the PDCH release and we switch PDCH right back on by accident? No, because
we only receive a chan rel ack when the *TCH/F* is being released.
That is because the PDCH release is initiated "internally" from the PDCH
DEACT, and thus this condition in common/rsl.c rsl_tx_rf_rel_ack() catches
on, which existed before dyn PDCH:
if (lchan->rel_act_kind != LCHAN_REL_ACT_RSL) {
LOGP(DRSL, LOGL_NOTICE, "%s not sending REL ACK\n",
gsm_lchan_name(lchan));
return 0;
}
In rsl_rx_rf_chan_rel() the rel_act_kind is set to LCHAN_REL_ACT_RSL, but
not in the rsl_rx_dyn_pdch().
This is analogous to the ip.access way -- the ip.access nanobts replies to
a PDCH DEACT with a PDCH DEACT ACK and doesn't send a separate channel
release ack.
Maybe we could set rel_act_kind to some new LCHAN_REL_ACT_IPAC_DYN_PDCH
for clarity? (But we shouldn't actually send a release ack, to stay
compatible.)
Even though it works as-is, we should indeed add another flag check:
- We do check the flags that no ACT/DEACT is already pending;
- And we do send a PDCH DEACT only if ts->flags & TS_F_PDCH_ACTIVE;
- But we would send a PDCH ACT despite ts->flags & TS_F_PDCH_ACTIVE.
This should never happen, but it would make sense to ensure that.

Hi,
I built libosmocore head (commit
84dcf73625513af44e711b2c99e21ee2c33b7eff at that time) on Fedora 43
(rawhide) and on s390x 4 tests failed. Iit's s390x running in qemu on
x86_64, but it also fails on native s390 - there I saw failures of
tests 25 26 69 90 (unfortunately I don't have the log from the native
run). So probably more tests can coredump, to see all the problematic
tests, it would probably require running through the valgrind. I am
reporting it according to the provided instructions
thanks & regards

Hi Experts,
I want to integrate EPC core (Open5GS) with open-source SGSN, It would be very helpful if anyone can share any document where I can find the installation steps and all.
Thanks in advance for your valuable time and consideration.

Sandip Biswas

Hi,
it came up again in gerrit again.
Currently the osmocom style states doxygen style comments should be done in the .c file.
Doxygen are those comments:
/*! a brief description of the function
* \param something Some description of the use
* \return 0 if ...
*/
Doxygen takes those comments and generates a html documentation of the code.
I would like to change it to have those in the headers files instead (when the function in included in a header file).
When using the doxygen comments only for doyxen, for sure, there isn't a difference between
having it in .c or in .h files.
But when using IDEs or language servers, they usually only parses headers files and
the .c files of the current active project (e.g. osmo-sgsn),
but not the .c files of other projects (libosmocore).
On the downside I only see the problem of increasing the size of header files, but I don't see
an issue in here.
Any thoughts?
Best,
lynxis
