2018-08-20use __FILE__, not __BASE_FILE__Neels Hofmeyr2-9/+9
The intention was to use the file's basename, but __BASE_FILE__ means "the root file that is being parsed and contains #include statements". If we had a function using __BASE_FILE__ and that was defined in an #included file, __BASE_FILE__ would indicate the first file where the #include is, and not the file where the function is defined. __BASE_FILE__ works for us because we don't ever include function definitions that log something, so __BASE_FILE__ always coincides with __FILE__ for our logging; but still __BASE_FILE__ is semantically the wrong constant.

2018-08-14osmo-msc: track the use of talloc NULL memory contextsVadim Yanitskiy1-0/+3
Tracking NULL memory contexts allows one to detect memory chunks, allocated outside the application's root context, which in most cases are results of some mistake. In b874486e8e48f033204bfcc86871dd851266d440 the repotring of NULL-context state was introduced, but without asking talloc to track the use of NULL memory contexts it doesn't make sense.

This example configuration files lack port settings for the mgcp client. Lets explicitly assign a port for the MGW and a local port. For the local port lets use the IETF port number + 1.

Since we don't process SS/USSD requests in OsmoMSC anymore, there are some useless GSM 04.80 functions remained from the past. In particular, this change does the following: - removes both gsm0480_send_{ussd_response|return_error} functions because they are not used anymore; - changes symbol prefix from 'gsm0480_' to 'msc_', in order to avoid possible conflicts with the libosmogsm's GSM 04.80 API; - cleans up useless includes; Change-Id: I2990d8627bce0ce6afb1dcf6b11bb194292380d3

This change introduces some new rate counters for call-independent SS/USSD connections. As OsmoMSC doesn't handle the messages itself, and only responsible for dispatching messages between both A and GSUP interfaces, the following is taken into account: - MS-initiated and network-initiated requests to establish a NC SS/USSD session (transaction) - "nc_ss:m{o|t}_requests"; - successfully established MS-initiated and network-initiated SS/USSD sessions (transactions) - "nc_ss:m{o|t}_established".

But the user may also initiate connection release, e.g. by pressing the 'red button'. TTCN-3 test case: I7936ed5072ed2ae02f039dc90a1fece1e7f70a70 Change-Id: I76fc277bf9db614a97824b1541cd5bb75aa3e29d

2018-07-30libmsc/gsm_09_11.c: forward SS/USSD messages to HLR over GSUPVadim Yanitskiy5-61/+223
In order to be able to support external SS/USSD gateway, we should not terminate the GSM 04.80 messages at OsmoMSC. Instead, we need to follow the GSM TS 09.11 specification, and forward all messages unhandled by OsmoMSC to OsmoHLR over GSUP protocol. This change implements forwarding of MO SS/USSD messages. The forwarding assumes transcoding between GSM 04.80 messages and GSUP messages. The payload of Facility IE is carried 'as is'. As a side-effect, this will disable the osmo-msc internal handler implementing the "*#100#" for obtaining the subscribers own phone number. In order to re-gain this functionality, you will need a modern osmo-hlr (Change-Id I1d09fab810a6bb9ab02904de72dbc9e8a414f9f9) and the following line in your osmo-hlr.cfg: hlr ussd route prefix *#100# internal own-msisdn TTCN-3 test case: I01de73aced6057328a121577a5a83bc2615fb2d4 Change-Id: Ide5f7e350b537db80cd8326fc59c8bf2e01cb68c
2018-07-29libvlr/vlr.c: forward unhandled GSUP messages towards MSCVadim Yanitskiy3-4/+20
Some internal sub-systems, such as SS/USSD or SMS implementation, may also need to use GSUP connection with HLR. Previously, it was only available within the libvlr code, and nowhere else. Let's introduce the generic GSUP message router, which will receive messages unhandled by VLR itself, and route them to a handler depending on the message type.

2018-07-29msc_vlr_tests: don't abuse USSD-request to conclude connectionsVadim Yanitskiy19-659/+488
Previously the '*#100#' USSD-request was abused in order to conclude the current subscriber connection. This makes the unit tests depend on each other, for example, if one break something in the GSM 09.11 implementation, a half of tests would fail. Moreover, the further changes in the GSM 09.11 implementation will make the results less predictable (i.e. session ID, etc.). So let's introduce a separate unit test with simple request- response logic, while more complex tests will be in TTCN. Change-Id: I40b4caac3113263f5a06c861dff5e10d43c319b5

The CC sub-layer is fairly self-contained, so let's move it to a separate C source file. The old gsm_04_08.c file now only contains the 04.07 / DTAP core and MM sub-layer handling. I did this initially as an experiment to see how self-contained our CC implementation really is. Given this rather straight-forward patch builds fine, CC really is self-contained (yay!).

2018-07-24git-version-gen: Don't check for .git directoryDaniel Willmann1-2/+2
This check is not in all our repos that use git-version-gen. Indeed it seems to be a leftover of openbsc where I think it wanted to ensure being called in the openbsc subfolder or something? libosmocore e.g. doesn't have it. In any case .git being a directory is not always true (if using git worktree) so remove this check. Change-Id: I9d895fa90991d47e9626a8e7fa701540b658194c

Overlong IMSIs in ID RESP messages were accepted and used in truncated form. Log an error when truncation occurs, and prevent truncated IMSIs from being installed for a subscriber via ID RESP messages. Other code paths leading to vlr_subscr_set_imsi() with truncated IMSIs will only a leave a trail of log entries for now, because vlr_subscr_set_imsi() is currently unable to return an error code.

2018-06-12libmsc/gsm_04_80.c: make the API abstract from ss_request structVadim Yanitskiy3-28/+77
There is no need to pass a pointer to a ss_request struct when calling the gsm0480_send_ussd_* functions, because they only use both transaction ID and InvokeID from there, which may be passed directly. This change allows one to use this API without parsing the whole GSM 04.80 message, or when parsing is failed. Moreover, if InvokeID is not available, one can pass any incorrect, (e.g. negative) value, so the universal NULL tag will be used. Finally, setting a TI flag is also up to the caller.

2018-06-12libmsc/gsm_09_11.c: properly indicate transaction errorsVadim Yanitskiy1-5/+6
Previously it was intended that we are always parsing the whole GSM 04.80 message, including the Invoke ID. But there is no need to do that, since we are going to forward the Facility IE payload to HLR in near future. Moreover, there was a mistake (my bad) - transaction is being established before parsing of the message, so the req structure remains uninitialized until that. Let's just send RELEASE COMPLETE message without any Cause or Facility IEs. We could indicate a problem using the first one, but according to GSM TS 04.80, the Cause IE only makes sense when "its functional handling is specified in the service description or GSM TS 09.11".

During a long time, we had both file and symbol names, actually related to Supplementary Services, with the 'ussd' abbreviation. This is not absolutely wrong, but isn't correct at the same time. USSD is a kind of Supplementary Services, this is only a part of them. There are also 'structured' Supplementary Services, which can be call related or call independent. The "Signalling interworking for supplementary services" is defined by GSM TS 09.11, and this is exactly what MSC should implement. Let's use the specification number for naming, as we do e.g. in the GSM 04.11 (SMS) implementation. Change-Id: Ic1eaceddb58132318e4e941be542da34b8ebefe1

2018-06-08libmsc/ussd.c: FIX: properly indicate errorsVadim Yanitskiy3-8/+41
There are error and problem codes defined by GSM TS 04.80: - Error codes are used when a message is structured correctly, but something is wrong in context of the current operation. Usually they are carried by 'Return Error' component. - Problem codes are used when something is wrong with the message structure, or with carried values. They are carried by 'Reject' component. There are three groups of them (see table 3.13): - General Problem Codes (table 3.14), - Invoke Problem Codes (table 3.15), - Return Result Problem Codes (table 3.16), - Return Error Problem Codes (table 3.17). The first group is general purpose, and can be sent in response to any kind of message, excluding 'Reject' itself. Other ones are bound to specific component types, such as 'Invoke', 'Return Result' and 'Return Error'. For some reason, a 'Reject' component with the general problem code 'GSM_0480_GEN_PROB_CODE_UNRECOGNISED' was always used in OsmoMSC. Even when the message structure is correct. Let's properly indicate errors in the following way: - 'Reject' with GSM_0480_GEN_PROB_CODE_UNRECOGNISED when the gsm0480_decode_ss_request() fails to decode a message. It can only return 0 or 1, so it's hard to guess which exact part of message caused the error. - 'Return Error' with GSM0480_ERR_CODE_ILLEGAL_SS_OPERATION when the operation code is not related to USSD. - 'Return Error' with GSM0480_ERR_CODE_UNEXPECTED_DATA_VALUE when the requested USSD code is unhandled (not supported). There is a TTCN-3 testcase for this: https://gerrit.osmocom.org/9470/ Change-Id: I800e7ec98dc9d0bca2d45a8b8255d60253d63e14

2018-05-23implement periodic Location Update expiry in the VLRStefan Sperling9-3/+264
Remove subscribers which fail to send periodic Location Updates from the list of subscribers known to the VLR. This complements the IMSI detach procedure: periodic LU expiry triggers an implicit IMSI detach. Expired subscribers are purged from a periodic timer which iterates over all subscribers once per minute. Subscribers with an active connection do not expire. This is controlled by the subscriber conn FSM which sets a subscriber's the LU expiry timeout value to GSM_SUBSCRIBER_NO_EXPIRATION while a connection is active. Add support for fake time with osmo_clock_gettime() to msc_vlr tests. This functionality existed in OpenBSC but was lost during the nitb split.
