Philipp Maier 72b8c38287 doc: do not use random ip-address for MGW
The example configs suggest to use a random ip-address as MGW address.
Lets use a loopback address here. This will suit the usual case where
MGW and MSC run together on the same machine.

Vadim Yanitskiy fc2b019cd8 libmsc: move subscriber expiration timer T3212 to libvlr
Since the split of OsmoNiTB, OsmoMSC does not deal with the radio
access network directly. Therefore the only purpose of T3212 is to
control subscriber expiration in the local VLR. The timeout value
indicated in System Information Type 3 needs to be configured
separately in the BSC/RNC.

This means that we don't need to store it in deci-hours anymore.
Let's move T3212 to the group of VLR specific timers, so it can
be configured and introspected using the generic 'timer' command,
and deprecate the old '[no] periodic location update' command.

It should be also noted that in the old code subscriber expiration
timeout was actually set to twice the T3212 value plus one minute.
After this change, we apply the configured value 'as-is', but
keep the old behaviour for 'periodic location update' command.

Vadim Yanitskiy baf71a72ec libvlr: use generic osmo_tdef API for T3250, T3260, and T3270
These timers so far were implemented as a list of unsigned integers,
which has never been initialized to any reasonable defaults. Since
they are used as state timeouts in several FSMs, we might end up
staying in some state forever.

Let's migrate to generic osmo_tdef API and use default values from
table 11.2 of 3GPP TS 24.008. This way the user can introspect and
change their values from the VTY / configuration file.

Vadim Yanitskiy ffc7f39f01 VTY: add osmo_tdef introspection and configuration commands
This change introduces several new VTY commands letting the user
a possibility to introspect and reconfigure some of the existing
timers implemented using libosmocore's osmo_tdef API.

At the moment this covers the following timers:

  - MGW specific timers:
    - X1 - MGCP response timeout,
    - X2 - RTP stream establishing timeout,

  - RAN specific timers (same names for GERAN and UTRAN):
    - X1 - Authentication and Ciphering timeout,
    - X2 - RAN connection release sanity timeout,
    - X3 - Handover procedure timeout.

The following commands are introduced:

  - 'enable' node:
    - show timer [(mgw|mncc|sccp|geran|utran|sgs)] [TNNNN]

  - 'config-msc' node:
    - timer [(mgw|mncc|sccp|geran|utran|sgs)] [TNNNN] [(<0-2147483647>|default)]

Both MNCC and SCCP related timer definitions are empty at the
moment. Achieved by using osmo_tdef_group API of libosmovty.

Neels Hofmeyr 63b246453b gsup: indicate CN-Domain in SendAuthInfo Requests
In order for osmo-hlr to be able to 100% guarantee distinct INDs for CS and PS,
set CN-Domain = CS in all SendAuthInfo Requests.

In Milenage auth, it is highly desirable that osmo-hlr guarantees use of
distinct INDs for CS and PS domains.  If an MSC and SGSN attached at the same
time use the same IND bucket to generate Milenage SQN, that collision would
rapidly waste SQNs and load osmo-hlr with requesting new auth tuples on each
CS/PS Complete-Layer3.

So far, osmo-msc did not indicate the CN domain in the GSUP SendAuthInfo
Request, which was neither required nor evaluated. The CN-Domain is only sent
for the UpdateLocation Request that usually follows later.

Neels Hofmeyr b455205783 MNCC v6: add optional SDP to the socket protocol
Add a char buffer of 1024 characters length as space for SDP to pass to /
receive from MNCC.

Actually support receiving MNCC without such an SDP tail. The main reason for
this is to avoid the need to adjust the ttcn3 implementation of MNCC: it would
stop working for older osmo-msc.

Older or non-SIP MNCC peers could operate the previous MNCC protocol unchanged
(save the protocol number bump) without having to implement SDP.

The SDP part in the MNCC protocol will be used in upcoming patch

This patch must be merged at the same time as osmo-sip-connector patch
Iaca9ed6611fc5ca8ca749bbbefc31f54bea5e925, so that both sides have a matching
MNCC protocol version number.

Neels Hofmeyr eef4578102 add sdp_msg API: SDP parsing/composition
Rationale: in order to add full SDP to the MNCC protocol (upcoming patch
I8c3b2de53ffae4ec3a66b9dabf308c290a2c999f), we need to parse and compose SDP
messages. Obviously, libosmo-mgcp-client already contains similar code, but
that is unfortunately heavily glued to the actual MGCP implementation. The
simplest solution is to create this separate implementation, copy-pasting from
the existing libosmo-mgcp-client code as is convenient.

This API is added here to probe whether it works well. When it does, the
intention is to "move it up" to osmo-mgw and overhaul the SDP parsing in our
MGCP client and MGCP server APIs using this same API.

Neels Hofmeyr 01653252b4 msc_a fsm: ignore state chg to same state
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.

When this switch is disabled with "no call-waiting" in vty
then when a call arrives, we will check if we have an active

establishing, established, or alerting, in any of these cases we
will return USER BUSY to the calling party.

To not break the msc_vlr tests by new GSUP IEs added to some of the GSUP

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 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.

- Again add test_umts_authen_utran() not using encryption.

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.

Vadim Yanitskiy 570b4c8be2 libmsc/db.c: get rid of hard-coded SMS expiry threshold
The initial idea of the SMS expiry threshold was to avoid storing
SMS messages with too long validity time (e.g. 63 weeks).
Unfortunately, neither this feature was properly documented, nor
the expiry threshold is configurable. Moreover, it has been
implemented in a wrong way, so instead of deleting the oldest
expired message, it would delete the youngest one or nothing:


while it should be sorted by 'valid_until' in ascending order:

  SELECT .. FROM SMS ORDER BY valid_until LIMIT 1;

Thus, if the oldest message is expired, it gets deleted. If the
oldest message is not expired yet, there is nothing to delete.

Apparently, dbi_conn_quote_binary_copy() doesn't properly handle
zero-length input. Let's guard against this.

Vadim Yanitskiy e1e7247500 Introduce initial unit test for db_sms_* API
Since OsmoMSC has built-in SMSC, it needs to store the messages
somewhere. Currently we use libdbi and SQLite3 back-end for that.

For a long time, the db_sms_* API remained uncovered by unit tests.
This change aims to fix that, and does cover the following calls:

  - db_sms_store(),
  - db_sms_get(),

  - db_sms_get_next_unsent(),
  - db_sms_mark_delivered(),

  - db_sms_delete_sent_message_by_id(),
  - db_sms_delete_by_msisdn(),
  - db_sms_delete_oldest_expired_message().

Due to performance reasons, the test database is initialized in
RAM using the magic filename ':memory:'. This is a feature of
SQLite3 (and not libdbi), see:

Of course, this unit test helped to discover some problems:

  1) Storing an SMS with empty TP-User-Data (TP-UDL=0) causes
     buffer overruns in both db_sms_store() and db_sms_get().

  2) TP-User-Data-Length is always being interpreted in octets,
     regardless of DCS (Data Coding Scheme). This results in
     storing garbage in the database if the default 7-bit
     encoding is used. Fortunately, the 'user_data' buffer
     in structure 'gsm_sms' is large emough, so we don't
     experience buffer overruns.

  3) db_sms_delete_oldest_expired_message() doesn't work
     as expected. Instead of removing the *oldest* expired
     message, it tries to remove the *newest* one.

The current test expectations do reflect these problems.
All of them will be fixed in the follow-up patches.

Vadim Yanitskiy 98f0675ffc tests: share stubs.h from msc_vlr_test as stubs.c
We also need stubs for the upcoming db_sms tests.

Due to a known bug of automake [1], we cannot use 'subdir-objects',
so as a side effect this change introduces some autoreconf warnings.

Oliver Smith cbf2c93d11 vlr: optionally send IMEI early to HLR
When 'check-imei-rqd 1 early' is set in the config, send the IMEI to
the HLR before doing the location update with the HLR.

The OsmoHLR documentation referenced in the code will be added in
osmo-hlr.git's Change-Id I2dd4a56f7b8be8b5d0e6fc32e04459e5e278d0a9.

Oliver Smith b8077b0c1d vlr: when setting IMEISV, also set IMEI
Copy IMEISV to IMEI when IMEISV changes. The additional SV digits will
get cut off then. This is needed for the subscriber on demand use case,
since we can get the IMEISV early (see [1]), but need to send the IMEI
to the Check IMEI procedure.

While adjusting the tests, I have noticed that there are code paths
where we ask the MS for the IMEISV first, and later ask the MS for the
IMEI, although we already have the IMEISV. This could be improved in a
future patch.

Note that there is also GSM23003_IMEI_NUM_DIGITS (15), which includes
an additional checksum digit. This digit is not intended for digital
transmission, so we don't need to store it. Also by not storing it, we
can simply copy the IMEI-part from the IMEISV to the IMEI without
worrying about the checksum (will be done in a follow up patch).

A good overview of the IMEI/IMEISV structure is here:

Oliver Smith 03ded913ad vty: make retrieve-imeisv-early configurable
Prepare for Rhizomatica's subscriber on demand use case, in which the
network access is disabled by default for new subscribers, but the IMEI
is required in the HLR to find out which user has which IMSI. Due to the
network access being disabled, the location update request towards the
HLR fails and the MS gets rejected, so we need to get the IMEI early.
