Re: [MERGED] openbsc[master]: gprs_sgsn.c: initialize ptmsi with 0xdeadbeef

by Neels Hofmeyr

NITB: high cpu usage and "crossed" messages when SMS table grows

by Keith

Hi all, I temporarily disabled a cron job we run at rhizomatica that purges the hlr SMS table of sent messages every day. After a few days I noticed slightly sluggish behaviour in the VTY, and sure enough, the nitb was consuming 100% cpu, not always, but presumably whenever it does a queue run. I also just heard that in the last few days, we got a number of reports from users, some confirmed by photos of the phones, about messages being delivered to the wrong destination. Apologies if this has been touched on before. I am not finding where I can directly search this list archives. Anyway, it might not be so bad to bring it up, as the cron job purging via cron job calling sqlite3 is not ideal, and anyway.. this crossed messages shouldn't happen, right? I imagine we'd like to track this one down. Keith.

osmo-bts-trx channel activation

by Max

Hi. This has been asked last year but to no avail, let's try again. How logical channels are (de)activated in osmo-bts-trx? For example in all the other models there's sapi_deactivate_cb() callback but osmo-bts-trx doesn't seem to be using sapi_cmd at all. To put this into perspective - while working on https://projects.osmocom.org/issues/1575 I got to activate/deactivate lchans when SI3 is received. This already works for sysmobts but I'd like to do the same for osmo-bts-trx as well. Is there any documentation somewhere describing how it works there? Or maybe someone more familiar with the code could help to shed the light on it? -- Max Suraev <msuraev(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 * Geschaeftsfuehrer / Managing Director: Harald Welte

autoconf and .deb question

by Max

Hi. There's strange thing about the way autoconf and debian/rules interact for OpenBSC: - in openbsc/include/openbsc/Makefile.am gsm_data_shared.h and common_cs.h are in noinst_HEADERS - in debian/openbsc-dev.install they are marked for installation And this actually works! If you run "dpkg-buildpackage -uc -us -tc" you'll get openbsc-dev*.deb with those headers properly installed. It's nice but feels a bit too much like magic. Any ideas how dh_install (or smth else?) manages to work around it? Should we be worried that it might break some time in future? Should we move those headers away from noinst_* section? -- Max Suraev <msuraev(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 * Geschaeftsfuehrer / Managing Director: Harald Welte

IMSI: Inf ?

by Keith

This is a bit vague again... I have found across our sites several entries with a value of Inf for IMSI on a create-on-demand subscriber: For example: sqlite> select * from Subscriber where id=284054; 284054|2017-03-08 21:19:40|2017-03-08 21:19:40|Inf||20649|0||0| I also have some Inf values for IMEI in Equipment: sqlite> select id,created,imei from Equipment where id = 95108; 95108|2014-03-13 03:18:06|Inf Not a big deal for operations, just thought I'd mention it as I noticed while restoring backups, (sqlite3 doesn't like to reimport the Inf value it writes itself with .dump)

BS-11 Serial Interface

by Alexander Huemer

Hi, I have a Siemens BS-11 with the factory cable for the LMT that has a DSUB-9 plug on the non-BTS end. When I connect a USB<-->RS232 adapter and run either $ cu -l /dev/ttyUSB or bs11_config -p /dev/ttyUSB0 I do not get any output when I switch on the BTS. I tried with nullmodem adapter and without just to be sure since I often mix up the pinouts. I was not able to measure any voltage on any of the DSUB-9 pins when the BTS is powered up, but believe that on either RX or TX there should be the voltage level of the serial line since RS232 is active low. Has somebody seen this behavior? -Alex

RFC: jenkins pipeline

by Klaus Müller

Hi, >> So, what would be the actual benefits? >>* complete job config in git? (to be confirmed) Just to clarify, the Pipeline plugin on its own doesn't provide a complete config handling in git. This means only the code shown in image [3] lives in git, configurations within the "General" or "Build Triggers" tab will still be handled in the web-ui.*** For the sake of completeness the JobDSL plugin [2][ has to be mention. This plugin allows to put the entire job configuration to git and deploys jobs without previous manual setup in the web-ui. >>* faster because less things have to be rebuilt? (to be confirmed) Somehow I doubt that this improvement dependents on the Pipeline plugin, but I know to few details to have an opinion based on facts. :) >>* faster because easily parallelizable/easier integration with docker? (to be >> confirmed) first point: e.g. Pipeline can trigger "down-stream-projects/stages" after one specific part of a parallel-block/matrix-configurations-project is finished. second point: Pipeline brings a docker wrapper, so one don't have to pass one build script holding the entire build sequence when invoking the container. You can invoke as much scripts as you want within the docker wrapper. (no black-box god-script :) >> If dr.blobb and/or Max could clarify these points that would be great >> (while I guess they will clarify in depth only after actual trials). >> First tests could run on a privately setup Jenkins ... dr.blobb? For sure, let's use this Jenkins instance [1] for trials. Everyone is welcome to sign up and send me a mail to get the necessary permissions. I start migrating the OpenBSC build pipeline to Pipeline and keep you updated. Is this mailing list the appropriate communication channel? Is there already a osmocom ci wiki page, which I overlooked? I'd be happy to contribute! ~André *** Some "web-ui configurations" can be injected from the jenkinsfile, though.

Maybe there is something wrong with the cable? This is from my notes about the BS-11 serial interface: The four E1 BNC connectors are here. 5 6 7 8 x x x x x x x x 1 2 3 4 2: LMT Tx (out) 6: LMT Rx (in) 4: +5V 8: GND There are two more 8-pin connectors below, you have to connect the cable to the top one (below the E1 BNC connectors). The same with some pictures is also here: https://osmocom.org/projects/openbsc/wiki/BS11LMT Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de
