This patch served for a manual testing counterpart for osmo-bsc to implement
MSC pooling.
This enables a basic MSC pooling setup, but for a production setup, osmo-msc
would still lack various features related to unloading subscribers to another
MSC as explained in 3GPP TS 23.236.

when the VTY write the config file ist prints the configuration line
for emergency-call in network and in msc, however the presence of the
configuration line in network leads to a parsing error on msc startup.
The vty command probably got moved to node msc and it was forgotten
to remove the printing from network.

There is an invalid Mobile Identity in the msc_vlr_test_gsm_ciph test data.
This became apparent when applying the new osmo_mobile_identity API (in a
following patch). Current Mobile Identity API ignores the error.

The SPEC file already included a build dependency to libsmpp34, but
then the compilation of osmo-msc didn't actually pass --enable-smpp
along, resulting in binaries without SMPP support - unlike the Debian
binaries, which do contain that part.

New define is available since libosmocore 1.1.0, and we already require
1.3.0, so no need to update dependenices.
Let's change it to avoid people re-using old BSC_FD_* symbols when
copy-pasting somewhere else.

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.

As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all.
For those builds LD shoud be set to clang too (and LDFLAGS needs the
sanitizer flags as well), because the clang compiler driver knows how
linking to the sanitizer libs works, but then at a later stage libtool
fails to actually produce the shared libraries and the build fails. This
is fixed by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan'
export CC=clang-10
ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`)
export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"

The problem is that osmo_rat_type_name() calls get_value_string(),
so we first cast -1 to 'const enum osmo_rat_type' and then to
'uint32_t'. Let's rather use OSMO_RAT_UNKNOWN.
Found by GCC with -Wextra in CFLAGS:
warning: operand of ?: changes signedness from ‘int’ to
‘const enum osmo_rat_type’ due to unsignedness
of other operand [-Wsign-compare]

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.

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.

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.

There was one libmsc commit to openbsc that was
thus far missing in osmo-msc.
This commit completes the work on delayed response
from an ESME. Without this patch, the SMR sends
an RP-ACK to the mobile station, and subsequently a
DELIVER_SM_REPONSE from the ESME provokes either a second
RP-ACK, or an RP-ERROR; both of which result in
"unhandled at this state (IDLE)" from the SMR
After this patch, we have two things corrected:
1) RP-ERROR respects Deliver-SM error cause.
2) No more "unhandled as this state" error from the SMR
Extract from original commit message:
--------
libmsc: annotate esme route in the sms object from deliver_to_esme()
Annotate this esme route, so we can use it to return -EINPROGRESS to
skip sending premature RP-ACK to the mobile station, in case we're
handling sms routes through SMPP.

difference to the same file in openbsc, which I found
while looking for changes that affected SMPP delivery.

During the last congress, we have noticed that OsmoMSC crashes
on receipt of malformed MM Identity Response messages:
BSSAP
Message Type: Direct Transfer (0x01)
Data Link Connection Identifier
00.. .... = Control Channel: not further specified (0x0)
..00 0... = Spare: 0x0
.... .000 = SAPI: RR/MM/CC (0x0)
Length: 11
GSM A-I/F DTAP - Identity Response
Protocol Discriminator: Mobility Management messages (5)
.... 0101 = Protocol discriminator: Mobility Management messages (0x5)
0000 .... = Skip Indicator: No indication of selected PLMN (0)
01.. .... = Sequence number: 1
..01 1001 = DTAP Mobility Management Message Type: Identity Response (0x19)
Mobile Identity - Format Unknown
Length: 8
.... 1... = Odd/even indication: Odd number of identity digits
.... .111 = Mobile Identity Type: Unknown (7) <-- This makes OsmoMSC crash
[Expert Info (Warning/Protocol): Unknown format 7]
[Unknown format 7]
[Severity level: Warning]
[Group: Protocol]
The value '111'B is not a valid Mobile Identity type, and shall be
considered as reserved according to 3GPP TS 24.008, section 10.5.1.4.
Later on it was discovered that '000'B also crashes OsmoMSC in the same way.
The crash itself is provoked by OSMO_ASSERT(0) in vlr_subscr_rx_id_resp().
Let's keep that assert in there, and make sure that:
- on receipt of MM Identity Response, Mobile Identity type
matches the one in MM Identity Request;
- on receipt of RR Ciphering Mode Complete, Mobile Identity
contains IMEI(SV) if present.

We shall not include additional BCD length octet into the value part
