Neels Hofmeyr f092301a0f ran_dec logging: log message sizes on errors

Neels Hofmeyr 4b78b29b8c vlr: don't log about "gratuitous ID RESPONSE"
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.

Keith Whyte 991bb422d4 Implement a global switch on the network to disable call waiting.
Add a network -> callwaiting VTY command as boolean.

When this is enabled (default) there is no change to
operation previous to this commit.

When this switch is disabled with "no call-waiting" in vty
then when a call arrives, we will check if we have an active
call transaction for this subscriber, no matter if it is
establishing, established, or alerting, in any of these cases we
will return USER BUSY to the calling party.

Neels Hofmeyr be5f033475 msc_vlr_tests: GSUP: don't care about extra IEs
To not break the msc_vlr tests by new GSUP IEs added to some of the GSUP
messages, make msc_vlr_tests only match the start of the GSUP message and not
care about extra IEs. The extra IEs are anyway seen in the expected logs.

The reason to drop the msgb_eq_data_print() is because it is useless for
mismatching lengths. It will always print only the length mismatch, instead we
need to be able to compare with what was expected.

Neels Hofmeyr 43a349fd63 tweak CC cause for incoming call to unattached nr
So far we sent CC cause "Unassigned Number"

But the MSC doesn't trivially know whether the HLR has the number assigned or
not: any handset that is currently switched off would cause "Unassigned number"
to be displayed on the caller's handset.

Rather send a temporary failure cause code.

Send this cause code for all cases, because claiming that an assigned number is
unassigned is worse than rejecting an unassigned number with a temporary

cleared. However, at the moment the MSC does not change the
cs.attached_via_ran flag. This may cause problems with the next call. Lets

Neels Hofmeyr 4dfb2babf2 add 'encryption uea 1 2' cfg / fix ttcn3 iu tests
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.

Adjust/add to test_nodes.vty transcript tests.

Neels Hofmeyr 106ba523c8 vlr_lu_fsm: fix missing event for IMEISV
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.

Neels Hofmeyr a4d7a76816 do not force encryption on UTRAN
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.

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.

Vadim Yanitskiy 59e0c6b46a gsm_04_11_gsup.c: fix broken reference counting for vsub
This change is similar to I5540556b1c75f6873883e46b78656f31fc1ef186.
In gsm411_gsup_rx() we do call vlr_subscr_find_by_imsi(), which
increases subscriber's reference count by one using the function
name as the token. However, we never release this token, so the
reference count grows on every received GSUP FORWARD-SM message.

Pau Espin fe5b7046ea sms_queue.c: Improve misleading log line
Otherwise when read in a log file it seems it's really going to send 20
sms even if there's none to send.

Vadim Yanitskiy 718f32fa88 libvlr/vlr.c: do not expire subscribers if periodic LU is disabled
When periodic Location Update is disabled (T3212 = 0), it was noticed
that OsmoMSC does expire subscribers quite soon - after 60 seconds

In order to avoid that, we need to check T3212 timer value in
vlr_subscr_expire_lu(), and if it's equal to 0, do not expire
anybody until the explicit IMSI Detach.

Vadim Yanitskiy 188dd5f4df tests/msc_vlr: fix: do not pass RAT type to expect_bssap_clear()
The function name implies OSMO_RAT_GERAN_A, and it has nothing
to do with other OSMO_RAT_* types. Found using clang:

  warning: too many arguments in call to 'expect_bssap_clear'

Vadim Yanitskiy 6632251572 libmsc/gsm_09_11.c: do not abuse LOG_TRANS() in gsm0911_rcv_nc_ss()
If we 100% sure that trans == NULL, it makes more sense to use
generic LOGP(DSS, LOGL_*, ...) call, so the logs can reflect
more information than such dummy prefix:

  trans(NULL NULL callref-0x0 tid-0) ...
