A patch for openbsc
by Alexander Huemer 26 Jan '16

OsmoBTS and T200 handling / libosmocore lapdm
by Harald Welte 26 Jan '16

26 Jan '16

Hi all, T200 is the LAPDm re-transmission timer, after which the sender assumes a L2 frame transmitted was lost and starts with recovery. Until recently, OsmoBTS ignored the T200 values that the BSC specified via OML, always falling back to the (relatively long) T200 values that exist in libosmocore (1s for the main channel, 2s for the associated channel). As you know, OsmoBTS is used in production in this configuration and we never recevied any associated bug reports. Recently, in e9f12acbeb5a369282719f8e0deecc88034a5488 I started to use the T200 values as communicated from the BSC via OML. This is what proprietary BTSs like the BS-11, nanoBTS etc. (supposedly) have been using all the time anyway, so I thought of it as a bug fix. However, as it turns out, it breaks our LAPDm implementation in many ways. The LAPDm performance gets that bad that you cannot even transmit a single SMS anymore, and even LU only occasionally work anymore. You can see the erroneous behavior in the attached PCAP file showing OsmoBTS-generated GSMTAP and RSL. Also attached are log file outputs of LAPDm logging for mo-sms and mt-sms. In them you can find troubling lines like 'S frame response with F=1 error' which should never happen... I suspect two issues related to this: 1) Our lapdm.c code uses regular osmo_timer_* functions to determine once T200 expires, rather than a GSM frame number time-base. This wouldn't be a problem in a synchronous real-time environemnt. However, in OsmoBTS (as in OsmocomBB), there is a relatively long and queue / delay between the point where a frame is pulled out of the bottom end of LAPDm and actual transmission on the radio interface. However, LAPDm T200 starts ticking from the point the frame was pulled out, rather than from the point transmission started. In order to change this, I suggest that we either change LAPDm timers to work on frame numbers passed up from L1 via every L1SAP primitive (comparing RTS.ind for downlink vs. DATA.ind for uplink), or simply keeping a per-PHY/per-TRX measurement of that 'round trip time between the actual radio and the L2'. We can then compensate for this by adding it to T200. I briefly tried this here, where one given hardware indicated about 56ms round-trip-time (13 frames difference between RTS.ind and DATA.ind). However, it didn't help. Even compensating by 120ms was not sufficient. This needs to be revisited. 2) I think libosmogsm LAPDm implementation is actually buggy, specifically in situations where T200 expires. We don't see that often, as the 1s/2s is so long that in reality it rarely happens. Once the T200 value is reduced, the probability of running into T200 expiration increases, and so does the probability of seeing related problems. Our existing lapdm unit tests don't seem to cover timing related behavior, so that definitely is something tha appears to need improvement. Any help on those issues is appreciated. Meanwhile, I decided to revert back to the libosmogsm T200 defaults by the means of commit 3ca59512d2f4eb1f87699e8fada67f33674918b4 Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Re: [PATCH] Enable address sanitizer for tests.

For them mem. leak sanitizer is explicitly disabled via > env. variables. I think it is best to use the OpenBSC mailinglist for libosmocore and other libraries. From my point of view it really makes sense to have ASAN build and run the tests (and include leak check if we can ignore some globals) but I have a couple of issues with the specific patch: 1.) not all compilers we use support ASAN 2.) Just compiling the test doesn't help us to verify the library itself. It needs to be instrumented too! So my proposal would be: 1.) We get a gcc 5.x or clang on one of the linux builders (or I will create one) 2.) We use your AT_CHECK check so we can pass this variable from the outside too. 3.) We have a Jenkins nightly job that does make CFLAGS+="-fsanitize.."

dbi deprecation

Hi, I'm just noticing warning: ‘dbi_initialize’ is deprecated (declared at /usr/include/dbi/dbi.h:169) called from openbsc/openbsc/src/libmsc/db.c:db_init() (and a couple more dbi deprecations) Should we do something about it? ...rather: who and when? ;) ~Neels -- - 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: Holger Freyther, Harald Welte

trx-bench results for AMD G-T40E
by Harald Welte 19 Jan '16

19 Jan '16

Hi Thomas, in case you'd like to add it to your benchmark results, below is a run of trx-bench on a Debian stable (jessie) system on a G-T40E CPU @ 800MHz. What I find surprising is that it appears to be comparable than the Atom D2500 @ 1.86GHz, despite the Atom running at twice the clock rate... More details see attachments.
