RFC: making libosmo-mgcp a non-installed static library

by Harald Welte

Hi all, I recently proposed the patch https://gerrit.osmocom.org/#/c/6270/ and I would like to get some input from a wider audience. Basically, it turns libosmo-mgcp (the mgw/server side MGCP lib) into an internal library similar to 'libmsc' in osmo-msc, which we don't expect to be used by other programs except osmo-mgw. Hence, there's no need to install it as a shared library, which introduces requirements about ABI/API stability and the like. osmo-bsc_nat uses libosmo-legacy-mgcp, and once we should rewrite osmo-bsc_nat, we might need some of the libosmo-mgcp related functions, but at this point it's unclear what exactly would be needed and if current libosmo-mgcp can provide that. As needed, we can introduce a related shared library at that point. Do you guys agree with this move, or do you think there is a point in having a public shared library with preferably stable API for the MGW side of MGCP? I think it just constrains us as to what we can do in terms of code changes within the MGW - for no clear benefit.

strange registering behaviour on osmo-bsc

by Sandi Suhendro

Dear list, I test again with new build for osmo-bsc osmo-msc-osmo-hlr I dont know if the osmo-hlr and osmo-bsc has been fixing or I have mistake for configuration which I did not change from the success I test before, but now I cannot register my phone and even make the network error and keep on emergency only when registering on the phone. at osmo-hlr I got this : 20180201190135844 DAUC <0003> hlr.c:79 510106127044410: IMSI known, but has no auth data; Returning slightly inaccurate cause 'IMSI Unknown' via GSUP Does the new osmo-bsc on master cannot use? or maybe I need to investigate more? Thanks for any feedback! -- Best Regards, DUO

On the use of 'decmatch' in TTCN-3

by Harald Welte

Hi, I know that TTCN-3 is still new to a lot of you, but we are writing tons of integration testing against the various osmocom programs in it. It is quite amazing technology, and I would like to ask you to bear with me reading this mail :) Pau was stating the question earlier today on not finding an example on how to use decmatch. Indeed, it took me some months to find that gem in the TTCN-3 world. It solves the problem that you often have during test of layered protocol stacks: you have separate encoders/decoders for each protocol layer, and now you want to match on some of the *inner* payload. So normally, you have some kind of header definition + a binary (octetstring) payload. This happens in RSL with the L3_INFO IE, and just the same on BSSAP/DTAP where again the L3 message (for example call control) is encapsulated inside one information element. Now you have multiple options of addressing the problem: a) hand-written calls to the decoder function b) write na 'emulation' for the entire protocol layer c) use decmatch. a) would look like this (pseudo-code): var octetstring l3oct; var RSL_Message rsl RSL.receive(tr_RSL_DATA_REQ(g_chan_nr, ?, ?)) -> value rsl { var PDU_ML3_MS_NW l3 := dec_PDU_ML3_MS_NW(rsl.payload); if (match(l3, some_template)) { ... do something } ... } Which uses the built-in pattern-matching on the RSL port to match any message that matches the tr_RSL_DATA_REQ template, and stores the resulting RSL message in a variable. It then uses an explicit call to the decoder function of the L3 message, and then uses regular conditional expressions for further matching on that inner L3 payload. This is more or less how you would write in C, python or any other quite imperative programming languages. It's very verbose, time consuming and un-abstract/elegant. TTCN-3 has many declarative aspects to it. Code like the above is a waste of your time :) b) would mean that you implement some test component that handles the RSL messages on its bottom side test port, and the L3 messages on its top side test port. That is a possible way, and if you need a lot of state/logic of RSL, it maeks sense. But what if you really simply want to have a match? Then it would be a lot of effort and a large detour. c) decmatch to the rescue! You can write RSL.receive(tr_RSL_DATA_REQ(g_chan_nr, ?, decmatch tr_RRM_RR_STATUS)) which means: * do a receive on the RSL test port, and match on an incoming RSL message that matches the tr_RSL_DATA_REQ template, with channel number specified, link_id any (?), *and* if the octetstring payload, if decoded, matches the template tr_RRM_RR_STATUS ! This is *extremely* powerful and expressive. It allows you to condense complex, parametric template matching over multiple proocol layers. It would in the end match RSL DATA REQUEST, only if they contained a [valid] encoded RR STATUS. See https://gerrit.osmocom.org/6229 for the actual test case I used for the above examples. Please also note that I never had to even write the function name of the decoder (dec_PDU_ML3_MS_NW), but TTCN-3 *automatically* figures out which decoder function it must call in order to decode from the binary octetstring.
