OsmoDevCon 2022 ?
by Harald Welte 10 Mar '22

10 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?

ttcn3-bsc-test-latest failures / tag a release?
by Neels Hofmeyr 10 Mar '22

10 Mar '22

Just now I looked at the failures in ttcn3-bsc-test-latest. https://jenkins.osmocom.org/jenkins/job/ttcn3-bsc-test-latest/ TL;DR: we should roll a release. Two real failures happen that are actual bugs in the latest release, and the rest of the failures are due to the lingering subscriber leak. BSC_Tests.TC_ho_into_this_bsc fails because osmo-bsc-latest omits the 'Codec List (BSS Supported)' in the Handover Request Acknowledge message, which is mandatory on AoIP. This error is fixed on osmo-bsc master. It makes no sense to me to punch a hole in the tests for latest -- this failure shows a real failure of the current osmo-bsc release. BSC_Tests.TC_cm_service_during_lcs_loc_req shows a subscriber leak, where a bsc_subscr is not cleaned up. This bsc_subscr lingers all the way to the end of the BSC_Tests run, and all other current failures of ttcn3-bsc-test-latest are due to that. (The only one not failing is TC_refuse_chan_act_to_vamos(), because it is the only one not verifying that no bsc_subscr stay behind.) So this also shows a real error in the current osmo-bsc release. There is nothing I would do at this point to make bsc-test-latest appear to be passing, because the errors shown are errors. The conclusion is that it might be time to roll another release one of these days. Related: important fixes I recently submitted are all merged to master, so from my side it would be a good time. ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

Applet not showing up after 9000 INSTALL for install
by Sabyrzhan Tasbolatov 04 Feb '22

04 Feb '22

Hello, I need help to understand my problem installing a simple HelloWorld applet on USIM card. There is already a USIM applet (AID: a0000000871002ffXXffXX89) running there, so perhaps that's the issue. 1. Should I remove it? Here is my code to INSTALL (for load), LOAD, INSTALL (for install): https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed 2. All of them returns 9000, which is OK, I'm using a simple CardReader, but when I insert the SIM to a phone, no applet comes up. Initially, I thought that the AID for instance is the reason. So when I do https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed#file-appl… ... module_aid="d07002CA44900101", app_aid="d07002CA44900101" I'm getting 6A88 (Referenced data not found). I changed it to A0000000871002FFffFFff8900000101 A000000087 - RID for 3GPP 1002 - USIM FFff - country code FFff - card issuer code 89 - Telecom 00000101 - App version? Havent figured out this yet the answer is 9000. But no app pops up on the phone once I insert SIM card back. 3. Also I'm checking if any load file actually ends up by taking some non-volatile space in SIM -- no difference. 4. After Install for install, there is nothing to be done, rght? Like updating EF_DIR is not required, where USIM is the only applet. Could you please assist? My twitter is twitter.com/novitoll Thanks, -- Sabr

INSTALL for install APDU failing
by Sabyrzhan Tasbolatov 21 Jan '22

21 Jan '22

Hello, Sorry, for the late reply. (replying again in new thread as prev mails failed). Quoted prev mails in quotes below. >> Which is "your test sim". Can you share the make and model? It's a sysmoUSIM-SJS1, I believe. I'm receiving 9000 for INSTALL for load, and for consequent LOAD commands 9000 as well. Only for the last INSTALL for install, I'm getting 6A88 (reference data not found). I think, the issue is in AIDs. I'm trying to figure out if I should use arbitrary bytes for AID or construct AID (which includes RID + RIX) the same way as existing Load Files, Applets' AID are on the SIM card? I'm using d07002CA44 from this https://github.com/mrlnc/HelloSTK2, I believe that should be reason for the 6A88 error code. Could you please assist?

Adding an ADF to SysmoISIM-SJA2
by bryan coxwell 17 Jan '22

17 Jan '22

Hello all, I'm looking for some guidance on adding an ADF which I will then be able to select by AID to a SysmoISIM-SJA2. Primarily I'm curious if there's any reason this WOULDN'T be doable before I continue down the rabbit hole of figuring it out. What I've tried so far is: 1) Pushing the applet to the SIM using shadysim_isim.py. It loads fine, and when I enable SIM toolkit it appears properly on my Android device. When I try to SELECT the AID however I get an error saying the AID doesn't exist. 2) I figure the above error is because EF.DIR doesn't include the AID, so I update the first empty record in EF.DIR to include the AID of my applet. When I try to SELECT the AID now I get the same error however. I'm not sure how to proceed but I figure now is a good time to see if it is in fact possible before spinning my wheels further. If anyone can point me in the right direction or even just a yes/no about whether it can be done that would be greatly appreciated. Best, Bryan
