* GSUP/SMS: introduce READY-FOR-SM messageVadim Yanitskiy2018-12-181-0/+13
| | | | | | | | | | | | | | | According to 3GPP TS 29.002, section 12.4, MAP-READY-FOR-SM is used between the MSC and VLR as well as between the VLR and the HLR to indicate that a subscriber has memory available for SMS. This change replicates this service in GSUP as READY_FOR_SM_*. The only mandatory IE for this service (excluding Invoke ID) is 'Alert Reason' that is replicated by OSMO_GSUP_SM_ALERT_RSN_IE.

* GSUP/SMS: introduce MO-/MT-FORWARD-SM messagesVadim Yanitskiy2018-12-184-2/+336
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to 3GPP TS 29.002, there are two services: - MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2), - MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9), which are used to forward MO/MT short messages. This change replicates both services as GSUP messages: - OSMO_GSUP_MSGT_MO_FORWARD_SM_*, - OSMO_GSUP_MSGT_MT_FORWARD_SM_*. Please note, that only the 'must-have' IEs are introduced by this change, in particular the following: - OSMO_GSUP_SM_RP_MR_IE (see note below), - OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1), - OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2), - OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4), - OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7), - OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4), where both SM_RP_DA and SM_RP_OA IEs basically contain a single nested TV of the following format: - T: identity type (see 'osmo_gsup_sms_sm_rp_oda_t'), - V: encoded identity itself (optional). According to GSM TS 04.11, every single message on the SM-RL has an unique message reference (see 8.2.3), that is used to link an RP-ACK or RP-ERROR message to the associated (preceding) RP-DATA or RP-SMMA message transfer attempt. In case of TCAP/MAP, this message reference is being mapped to the Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not required for other applications (other than SMS), this change introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

* gsm48_mi_to_string: use osmo_bcd2str(), fix some corner casesNeels Hofmeyr2018-12-101-13/+12
| | | | | | | | | | | | | By using osmo_bcd2str(), ensure that the resulting string is always nul terminated, and always return strlen()+1 whether truncated or not. Still keep up the previous return value style, even if that isn't consistent at all. The difference between IMSI/IMEI and TMSI return values remains and is not part of this patch.

* gsm0808: add encoder for cause codes and use itPhilipp Maier2018-12-083-12/+43
| | | | | | | | | | | | | | | | At the moment the all gsm0808 cause codes are encoded directly using the tlv API directly to put a one byte TLV field. This works ok for most situations where the cause code consists of a single byte. However, gsm0808 specifies a two byte cause code model where cause codes may be extended up to two bytes. Instead of implementing the encoding over and over and again, let's rather have an encoder function we can call. - Add an encoder function that can generate single byte and extended cause codeds and makes the length decision automatically. - Use only this function to append cause codes Change-Id: I71d58fad89502a43532f60717ca022c15c73f8bb

* gsm: Deprecate buggy gsm_arfcn2band API and introduce gsm_arfcn2band_rcPau Espin Pedrol2018-11-202-23/+49
| | | | | | | | | | | | | | | | | | | ARFCNs are values in well defined ranges. Until this patch, ARFCNs not belonging to any band were blindly assigned to DCS1800 by gsm_arfcn2band, causing unnoticed bugs and misconfigurations in osmo-bsc. Previous API gsm_arfcn2band cannot accomodate this kind of check easily, so let's deprecate it to tell people to use a new API gsm_arfcn2band_rc which performs this kind of checks and allows callers to log failures, misconfigurations, etc. At the same time, modify implementation of gsm_arfcn2band to abort if an invalid ARFCN is passed, this way users of this API can notice they are passing wrong data to it that most probably will produce unexpected results.

* gsm0808: allow decoding of zero length speech codec lists.Philipp Maier2018-10-161-10/+0
| | | | | | | | | | | | | | | | | | | | | 3GPP_TS_48.008, 3.2.2.103 Speech Codec List states the following: "The length indicator (octet 2) is a binary number indicating the absolute length of the contents after the length indicator. The length depends on the number and type of Speech Codec Elements to be included. The minimum length of one Speech Codec Element is 1 octet and the maximum length is 3 octets. The maximum number of Speech Codec Elements within the Speech Codec List is not defined." This clearly refers only to the length of a single speech codec element but not on the overall list. So speech codec lists with length 0 are indeed permitted by the spec. - Remove the assertion that checks on zero length speech codec lists.
