stow fallout, problem in osmo-bts-sysmo build
by Neels Hofmeyr 16 Jan '18

16 Jan '18

In osmo-bts, we just have the configure flag --enable-sysmocom-bts, and don't pass a header include location. i.e. we expect the header files to exist locally. I'm a bit stumped on why introducing stow would cause this to break. IIUC stow should only affect the installed dependencies, while the sysmocom headers are just placed in a local dir? If we can't fix the osmo-bts build quickly, we'll have to revert the stow patch until that works. https://jenkins.osmocom.org/jenkins/view/master/job/master-osmo-bts/36/BTS_… The build scripts are (obviously) in osmo-bts/contrib/ and osmo-ci/scripts. Any help is appreciated. ~N

External USSD interface development
by Vadim Yanitskiy 16 Jan '18

16 Jan '18

Dear Harald, In this mail I would like to express my thoughts and ideas regarding to the 'external interface for USSD'. To provide some background for other mailing list members, who are not aware of this topic, I'll explain it in a few sentences. We already have an external interface for SMS - SMPP. But unfortunately, the same cannot be said about USSD. There is no built-in support of any interface, which could be used to handle USSD requests in a separate application. So, at the moment we only handle *#100# (own number request), which is implemented as a part of both OsmoMSC and legacy OsmoNiTB. And if one would like to implement additional USSD commands, it's required to modify and recompile the whole project :/ Fairwaves team already have some draft implementation for legacy OsmoNiTB, which relays on the libosmocore's GSM 04.80 API. And having the external interface in the mainline would be great not only for Fairwaves, but for the whole Osmocom project and its users. The problem is that the current libosmocore's GSM 04.80 API is not complete and requires some critical modifications, which of course cannot be integrated immediately. Moreover, this implementation doesn't follow Osmocom coding style, for example, unlike other functions, where return code rc = 0 means success, there it means error... So, first of all, we need to know, how many projects are using the current API, especially non-Osmocom projects. After that (taking it into account), it shall be decided: - Should we keep the old API / ABI and maintain all new features among with it. This way would force us to duplicate the existing code and use different symbols. Then the old API would continuously became deprecated... - Should we make all the critical changes in the current API (increasing the libosmocore version?). This way would break builds of dependent projects and would suppose fixing compatibility with the new API. But, at the same time, the implementation would be cleaner and closer to the specification, without any deprecated duplication... Personally, I prefer the second way. At the same time, I want to make the modification as much transparent as possible. Speaking about Osmocom projects, the only users of the GSM 04.80 API are OsmoMSC and legacy OsmoNiTB. Both projects utilize it for '*#100#' handling only :/ To be more convincing, let's look at the following code: #define MAX_LEN_USSD_STRING 31 struct ss_request { uint8_t opcode; uint8_t ss_code; uint8_t ussd_text[MAX_LEN_USSD_STRING + 1]; uint8_t transaction_id; uint8_t invoke_id; }; This is what the current API allows you to obtain from a SS-request (e.g. '*#100#') coming from user. And what's wrong here? - The 'ss_request' doesn't indicate a part of the library it comes from. Would be better to use 'gsm0480_ss_request'. - The 'ussd_text' length doesn't follow the specification, where USSD OCTET STRING length is 160 bytes. So, the amount of characters depends on used coding scheme. - The information about SS-message type, component type, text length and used DCS (Data Coding Scheme), etc. is missing. Despite it could be important for the external application. So, let's discuss together all the 'pros and cons', and decide together, how should we facilitate the external USSD interface development. With best regards, Vadim Yanitskiy.

osmo-bsc_nat dropped in unrelated patch
by Neels Hofmeyr 16 Jan '18

16 Jan '18

Hi dexter, reading a commit of yours apparently merged to osmo-bsc in November, I notice that you "secretly sneaked in" this: diff --git a/src/Makefile.am b/src/Makefile.am index d04f025..dd1ad3d 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -33,5 +33,4 @@ SUBDIRS += \ utils \ ipaccess \ osmo-bsc \ - osmo-bsc_nat \ $(NULL) in a patch that was supposed to "mgcp: use osmo-mgw to switch RTP streams". http://git.osmocom.org/osmo-bsc/commit/?id=39c609b7c924524172ad311bdf89f92b… So since we merged that patch, osmo-bsc_nat is no longer part of the osmo-bsc build. That's certainly not intended, is it? Confirm and please fix that. thx! ~N

USRP2 and OsmoTRX
by Rafael Diniz 16 Jan '18

Hi people, I'm doing some tests with an old USRP2 + RF900 daughterboard, and I get a very unstable system (with osmo-trx, osmo-bts-trx and osmo-nitb) - some phones can connect, some dont. I'd like to identify the problem - is it a bad GBit ethernet or the lack of a GPSDO connected to the 10MHz port?

osmo-trx test setup & convolve_test failures on different machines
by Pau Espin Pedrol 15 Jan '18

15 Jan '18

Hi everybody, as some of you may have noticed due to the generated noise in gerrit ml during last days, I have been adding some autotest setup to osmo-trx in order to have several tests being run during gerrit review. Since osmo-trx has some specific code built with NEON instructions, I also added some infrastructure to jenkin.sh to generate and use a prebuilt debian armhf rootfs so we can easily build and run tests using qemu-arm from our local workstations or from jenkins slaves, which will check that support for those architectures doesn't become broken. In order to set up the make check tests, I re-used existing tests and moved them to the tests/ directory. I also moved utils/convolvtest/main.c into "tests/Transceiver52M/convolve_test" [1] to become a test that checks "convolve_{real,complex}" APIs. I noticed, however, that this test prints slightly (or not that slightly) different outputs on different machine architectures, which of course make tests fail as it matches the exact values. So far the output is different in my x86_64 workstation, my i686 netbook (or i586 OBS host) and in my qemu-arm (armhf). As each machine uses different instructions sets, I indeed can understand that there appear small differences due to floating operations and rounding, but sometimes I can see relatively big difference between one implementation and the other one (eg 7.032490 vs 6.655972). I'm thinking about modifying the test to, instead of matching the output exactly, check that for each value in the vector it is similar to a value with a maximum epsilon distance from a reference vector. However, as I don't have any knowledge regarding the maths and theory behind the convolution codes, I must admit I am not sure which epsilon should I be using, or which should be the expected output for the test. It may perhaps make sense to have separate reference output for different architectures, I don't know. Can somebody shed some light on this topic? Any advise or hint is welcome. It would also be nice to have some tests for the "convert" API, which uses optimized instructions sets too. If somebody wants to provide those or any hint on how to implement them that's going to be handy. All the test infrastructure is merged now, only the patch adding the qemu part is not merged but already working in [2], I'll merge it tomorrow if nobody is angry with it. You can find related output for the test I was speaking of for different machine arch (x86_64, i686, arm) in [3] and [4].
