Max 753c15de2f Migrate from OpenSSL to osmo_get_rand_id()
This avoids potential licensing incompatibility and makes integration of
Debian packaging patches easier.

Neels Hofmeyr a99b42709a add msc_vlr_test_call to reproduce a sanitizer error
On MT call, there is a bug in CC conn use which leads to an early free and
use-after-free.

Add msc_vlr_test_call to show both MO and MT call legs separately and reproduce
the failure. It is visible in a sanitizer build (on debian 9).

A subsequent patch will fix the bug: If0659a878deb383ed0300217e2c41c8c79b2b6a5

Neels Hofmeyr 96748ca790 msc_vlr_tests: fix rebuild: rebuild when src/ libs were rebuilt
Before this, a code change in libvlr or libmsc would not cause a rebuild of the
tests.

You'd have thought 'AM_LDADD' were the right name for the variable, but
apparently it is just 'LDADD' instead. Tested that it works as intended.

Harald Welte 8f042b9000 osmo-msc: Don't link against libasn1c
osmo-msc doesn't use any API/symbols of libasn1c directlry.  Rather,
we use libosmo-ranap which in turn uses libasn1c.  Let the linker
work out that dependency.

This fixes the following dpkg-shlibdeps warning:

dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/osmo-msc/usr/bin/osmo-msc was not linked against libasn1c.so.0 (it uses none of the library's symbols)

Neels Hofmeyr 6c8afe148b use separated libosmo-mgcp-client, apply rename to mgcp_client_*
After osmo-mgw changes I8e0b2d2a399b77086a36606f5e427271c6242df1 and
I99f7faab637cfcc22ece64a1dbcbe590f2042187, apply linking of new
libosmo-mgcp-client and renames to drop the "gw" from mgcp_client_*.

Also rename the gsm_network.mgcpgw to mgw, to indicate that the MGCP client is
used to contact the MGW (Media Gateway).

Neels Hofmeyr f7251c3aa1 am: msc_vlr_tests: use AM_LDFLAGS instead of COMMON vars
It was a n00b mistake to define COMMON_LDFLAGS and COMMON_LDADD to pass the
same linker options to each test binary. Instead, use AM_LDFLAGS and remove the
autoreconf warning.

    tests/msc_vlr/Makefile.am:66: warning: variable 'COMMON_LDFLAGS' is defined but no program or
    tests/msc_vlr/Makefile.am:66: library has 'COMMON' as canonical name (possible typo)

Neels Hofmeyr 979cd26f35 move to osmo-mgw.git: osmo-bsc_mgcp and libmgcp as libosmo-legacy-mgcp
Rewire build and includes to libosmo-legacy-mgcp.

Drop osmo-bsc_mgcp and related python tests, now found in osmo-mgw.git.

libosmo-legacy-mgcp is installed from osmo-mgw, hence add the dependency to
jenkins.sh (so far using the pre_release branch).

Neels Hofmeyr 00e82d61ab move libiu to osmo-iuh/libosmo-ranap
Remove libiu here, use the functions from libosmo-ranap instead, by applying
the ranap_ / RANAP_ prefix.

Corresponding change-id in osmo-iuh.git is I6a3f7ad15be03fb94689b4af6ccfa828c25f45c0

To be able to run the msc_vlr tests for RAN_UTRAN_IU without Iu client headers
available, add iu_dummy.h, containing mere function signatures that match
iu_dummy.c and a mostly empty struct ranap_ue_conn_ctx.

Make sure we can build with and without --enable-iu: include osmo-iuh headers
only with --enable-iu.

Philipp Maier fbf6610dc1 Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)
This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.

Implement AoIP in osmo-msc and osmo-bsc.

Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.

From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN

jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new
M3UA SIGTRAN.

Neels Hofmeyr 84da6b1edb Implement IuCS (large refactoring and addition)
osmo-nitb becomes osmo-msc
add DIUCS debug log constant
add iucs.[hc]
add msc vty, remove nitb vty
add libiudummy, to avoid linking Iu deps in tests
Use new msc_tx_dtap() instead of gsm0808_submit_dtap()
libmgcp: add mgcpgw client API
bridge calls via mgcpgw

Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to
be split up.

Neels Hofmeyr e2f24d53e4 mscsplit: various preparations to separate MSC from BSC
Disable large parts of the code that depend on BSC presence. The code sections
disabled by #if BEFORE_MSCSPLIT shall be modified or dropped in the course of
adding the A-interface.

Don't set msg->lchan nor msg->dst.
Don't use lchan in libmsc.
Decouple lac from bts.

Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication:
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to
different interfaces depending on the actual subscriber connection.
While iu_tx() is going to be functional fairly soon, the a_tx() is going to be
just a dummy for some time (see comment).
Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer
and an indicator for the Integrity Protection status on Iu (to be fully
implemented in later commits).
Add lac member to gsm_subscriber_connection, to allow decoupling from
bts->location_area_code. The conn->lac will actually be set in iu.c in an
upcoming commit ("add iucs.[hc]").

move to libcommon-cs: gsm48_extract_mi(), gsm48_paging_extract_mi().

libmsc: duplicate gsm0808 / gsm48 functions (towards BSC).
In osmo-nitb, libmsc would directly call the functions on the BSC level, not
always via the bsc_api. When separating libmsc from libbsc, some functions are
missing from the linkage.
Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also
add a _tx to gsm0808_cipher_mode():
* add msc_gsm0808_tx_cipher_mode() (dummy/stub)
* add msc_gsm48_tx_mm_serv_ack()
* add msc_gsm48_tx_mm_serv_rej()
Call these from libmsc instead of
* gsm0808_cipher_mode()
* gsm48_tx_mm_serv_ack()
* gsm48_tx_mm_serv_rej()
Also add a comment related to msc_gsm0808_tx_cipher_mode() in two places.

Remove internal RTP streaming code; OsmoNITB supported that, but for OsmoMSC,
this will be done with an external MGCP gateway.

Remove LCHAN_MODIFY from internal MNCC state machine.

Temporarily disable all paging to be able to link libmsc without libbsc.
Skip the paging part of channel_test because the paging is now disabled.
Employ fake paging shims in order for msc_vlr_tests to still work.

msc_compl_l3(): publish in .h, tweak return value.  Use new libmsc enum values
for return val, to avoid dependency on libbsc headers.  Make callable from
other scopes: publish in osmo_msc.h and remove 'static' in osmo_msc.c

add gsm_encr to subscr_conn
move subscr_request to gsm_subscriber.h
subscr_request_channel() -> subscr_request_conn()
move to libmsc: osmo_stats_vty_add_cmds()
gsm_04_08: remove apply_codec_restrictions()
gsm0408_test: use NULL for root ctx
move to libbsc: gsm_bts_neighbor()
move to libbsc: lchan_next_meas_rep()
move vty config for t3212 to network level (periodic lu)
remove unneccessary linking from some tests
remove handle_abisip_signal()
abis_rsl.c: don't use libvlr from libbsc

gsm_subscriber_connection: put the LAC here, so that it is available without
accessing conn->bts. In bsc_api.c, place this lac in conn for the sake of
transition: Iu and A will use this new field to pass the LAC around, but in a
completely separate OsmoBSC this is not actually needed. It can be removed
again from osmo-bsc.git when the time has come.

Siemens MRPCI: completely drop sending the MRPCI messages for now, they shall
be added in osmo-bsc once the A-Interface code has settled. See OS#2389.
