2019-09-18fix error on BSSMAP Cipher Mode Complete L3 msg IENeels Hofmeyr3-11/+16
When an MS returns the IMEISV in the BSSMAP Cipher Mode Complete message in the Layer 3 Message Contents IE, do not re-invoke the decode_cb() a second time, but instead point to it from the ran_msg.cipher_mode_complete struct. When the MSC-A decodes the Ciphering Mode Complete message, it always wants to also decode the enclosed DTAP from the Layer 3 Message Contents IE. However, when the MSC-I preliminarily decodes messages, it often just wants to identify specific messages without fully acting on them, let alone dispatching RAN_UP_L2 events more than once. So leave it up to the supplied decode_cb passed to ran_dec_l2() implementations to decide whether to decode the DTAP. In msc_a.c hence evaluate the DTAP by passing a msgb to msc_a_up_l3(), which will evaluate the RR Ciphering Mode Complete message found in the BSSMAP Cipher Mode Complete's Layer 3 Message Contents IE. Particularly, the previous choice of calling the decode_cb a second time for the enclosed DTAP caused a header/length parsing error: the second decode_cb call tried to mimick DTAP by overwriting the l3h pointer and truncating the length of the msgb, but subsequently ran_a_decode_l2() would again derive the l3h from the l2h, obliterating the intended re-interpretation as DTAP, and hence the previous truncation caused error messages on each and every Cipher Mode Complete message, like: DBSSAP ERROR libmsc/ran_msg_a.c:764 msc_a(IMSI-26242340300XXXX:MSISDN-XXXX:TMSI-0xA73E055A:GERAN-A-77923:LU)[0x5563947521e0]{MSC_A_ST_AUTH_CIPH}: RAN decode: BSSMAP: BSSMAP data truncated, discarding message This error was seen a lot at CCCamp2019. Modifying the msgb was a bad idea to begin with, the approach taken in this patch is much cleaner. Note that apparently many phones include the IMEISV in the Cipher Mode Complete message even though the BSSMAP Cipher Mode Command did not include the Cipher Response Mode IE. So, even though we did not specifically ask for the Cipher Mode Complete to include any identity, many MS default to including the IMEISV of their own accord. Reproduce: attach to osmo-msc with ciphering enabled using a Samsung Galaxy S4mini. Related: OS#4168 Change-Id: Icd8dad18d6dda24d075dd8da72c3d6db1302090d

2019-09-03msc_a fsm: ignore state chg to same stateNeels Hofmeyr5-13/+8
We sometimes see errors like libmsc/msc_a.c:361 msc_a(...){MSC_A_ST_RELEASING}: transition to state MSC_A_ST_RELEASING not permitted! i.e. changing state to the state msc_a is already in. Ignore re-entering the same state for most state changes. However, there is one state change in msc_a where re-entering the MSC_A_ST_VALIDATE_L3 is necessary to start the timeout. Hence add msc_a_state_chg_always() and use that for re-entering MSC_A_ST_VALIDATE_L3. Change msc_a_state_chg() to skip no-op state changes. This should silence all no-op state change error messages for msc_a. Related: OS#4169 Change-Id: I0c74c10b5fa7bbdd6ae3674926cc0393edf15a35

If an ID Response comes in during a non-LU L3 Complete (Paging or CM Service Request), no event needs to be dispatched. So far vlr_subscr_rx_id_resp() logged a NOTICE "gratuitous ID RESPONSE?!?" if no lu_fsm is present. An ID Response can come in particularly as payload with a BSSMAP Cipher Mode Complete message, even though osmo-msc didn't explicitly ask for it. It is not an error to get a Cipher Mode Complete containing an ID Response during Paging or CM Service Request, so remove the confusing log message.

2019-08-13add 'encryption uea 1 2' cfg / fix ttcn3 iu testsNeels Hofmeyr10-62/+153
Recently, the ability to run UTRAN without encryption was added, but the config for it was tied to the A5 GERAN encryption configuration. This affected osmo-msc's default behavior of Iu, breaking osmo-msc ttcn3 Iu tests: the ttcn3 test suite sets A5 to 0 (no encryption) but still expects Iu to enable air encryption. Fix this "regression". Add a separate vty config option for UEA encryption, even if it does not provide full granularity to select individual UEA algorithms yet. As a result, Iu default behavior remains to enable encryption regardless of the A5 config. UTRAN encryption can be disabled by the new cfg option "encryption uea 0" alone. Even though the new vty command already allows passing various combinations of the UEA algorithm numbers, only '0' and '1 2' are accepted as valid combinations, to reflect current osmo-msc capabilities. Revert most changes to the msc_vlr test suite in commit "do not force encryption on UTRAN" (I04ecd7a3b1cc603b2e3feb630e8c7c93fc36ccd7): use new net->iu_encryption instead of net->a5_encryption_mask.

2019-08-08vlr_lu_fsm: fix missing event for IMEISVNeels Hofmeyr1-0/+1
Event VLR_ULA_E_ID_IMEISV is listed as permitted in VLR_ULA_S_WAIT_LU_COMPL, but is missing from the switch() on the incoming event. So, sending an IMEISV identity during the WAIT_LU_COMPL state would crash osmo-msc. When receiving an IMEISV, vlr_subscr_set_imeisv() in turn calls vlr_subscr_set_imei(), so as far as the lu_fsm is concerned, receiving an IMEISV is identical to receiving an IMEI, and it can continue to send a Check IMEI request to the HLR. Thus simply add VLR_ULA_E_ID_IMEISV to the VLR_ULA_E_ID_IMEI switch case. Change-Id: I11106cb108a4b1406ff9a8b8ff5761440a274dad

2019-08-05do not force encryption on UTRANNeels Hofmeyr7-5/+48
Remove the conditions that always enable encryption on UTRAN. We so far lack an explicit configuration for UTRAN encryption, and this patch does not add any either. Instead, whether UTRAN encryption is enabled is simply triggered on whether GERAN has A5 encryption enabled (A5/n with n > 0). Though GERAN and UTRAN encryption are not technically related at all, this makes UTRAN behave like GERAN for now, until we implement a proper separate configuration for UTRAN encryption. Adjust the msc_vlr_test_* configuration by setting the net->a5_encryption_mask such that the expected output remains unchanged. A subsequent patch (I54227f1f08c38c0bf69b9c48924669c4829b04b9) will add more tests, particularly cases of UTRAN without encryption. Adjust manual and vty doc.

2019-06-20libmsc/ran_msg_iu.c: fix: properly handle SAPI IE of RANAP_DirectTransferVadim Yanitskiy1-2/+12
The RANAP DirectTransfer message may contain an optional SAPI IE. Thanks to our TTCN-3 tests (and Wireshark!), it was discovered that this IE is ignored, so even if the MO SMS related messages arrive on SAPI 3 (as per GSM TS 04.11, section 2.3) OsmoMSC sends MT messages on SAPI 0. In ran_iu_decode_l3() we need to check if the SAPI IE is present, and tag the NAS PDU message buffer with a proper DLCI value. This change makes the failing SMS related test cases pass.

2019-06-20libmsc/gsm_04_11.c: do not abuse LOG_TRANS() in gsm411_alloc_mt_trans()Vadim Yanitskiy1-2/+2
This change is similar to I6b68a0f0b32eb126e0f7e914a314130254d28467. If we 100% sure that trans == NULL, it makes more sense to use generic LOGP(DLSMS, LOGL_*, ...) call, so the logs can reflect more information than such dummy prefix: trans(NULL NULL callref-0x0 tid-0) ...
