When configuring osmo-mgw the user may choose an arbitrary trunk number
for the E1 trunk and sets a line number that must match the number of
the physical line that is used with the particular trunk. This is easy
to confuse, so lets add a note to the maual that mekes this clear.

We have VTY options that allow to set the DSCP value. However, we
then call a function to set the TOS bits in the kernel. This is
very wrong. The DSCP is only the upper 6 bits of the 8-bit TOS
value, and hence we are mussing that translation.
As libosmocore now has a helper function osmo_sock_set_dscp(),
let's make use of it and don't care about the low-level details.
However, this means we need to finally remove the deprecated
alias for "rtp ip-tos <0-255>".

Add a graph similar to "OsmoMGW used with OsmoMSC" that shows the
integration of a legacy E1 BTS into a AoIP network
Change-Id: I71dc2f4a188fbc25e81050be3dd4c83e1797e63d
The graph "OsmoMGW used with OsmoMSC" shows a BSC entity that accepts
AoIP and RTP, however osmo-bsc has no RTP proxy functionality. It makes
probably more sense to remove the BTS from the graph and call "BSC" "2G
BSS"
Change-Id: I6c7d26b6e45d0f953b82bca3ae7b2f26600982b2
The graph "OsmoMGW used with OsmoBSC" shows an RTP and 3GPP AoIP going
to OsmoMSC, this is technically wrong since osmoMSC has no RTP proxy
functionality whatsoever. Since the graph is not so much about OsmoMSC
it makes more sense to label OsmoMSC with "core-network", then it makes
sense and correctly highlights the role of osmo-mgw on the BSS side.

Leave the old osmo-bsc_mgcp and libosmo-legacy-mgcp as it is; on a copy thereof
(added by a previous commit), apply changes to initially implement the new
osmo-mgw.
Adjust build system and debian packaging to accomodate the new libosmo-mgcp and
osmo-mgw.
The main differences:
*) use a list to manage rtp connections.
Aggregate all rtp related information inside a single struct.
Use a linked list to manage the both connections (net and bts).
The idea behind using a list is that we might support conference
calls at some later point.
Store the linked list in struct mgcp_endpoint, have a private linked
list for each endpoint. The list contains connection items which are
implemented in struct mgcp_conn. A connection is allocated and freed
using the functions in mgcp_conn.c. A connection is allocated on the
reception of a CRCX command and freed with the reception of a DLCX
command.
*) remove external transcoder feature
Fortunatelly the external transcoder feature is not needed
anymore. This patch removes the related code.
*) vty: get rid of CONN_BTS and CONN_NET
Since the new connection model does not make a difference
between BTS and NET connections the VTY should not use
the fixed CONN_BTS and CONN_NET constants.
- Handle the conns list inside the endpoint directly
- introduce function to dump basic rtp connection info
- introduce human readable names for connections
Parts of the code adjusted to use generalized connections instead of explicit
BTS/NET ones:
- teach mgcp_send_dummy() to send dummy packets to any RTP connection
- network: generalize mgcp_bind_net/bts_rtp_port()
- network: generalize mgcp_send()
- tap: generalize call tapping feature
- stat: generalize statistics
- Replace rtp_data_net() and rtp_data_bts() with generalized rtp_data_rx()
*) mgcp_protocol.c fixes:
- check ci string before it is converted:
In case of missing ci, a nullpointer is delivered to strtoul().
Add a function that takes ci, checks it and converts it to an
uint32_t. Use the return code to react on missing ci.
- output error message on missing CI.
- when parsing the mode, print log message when mode is missing.
- use mode_orig when mode is missing.
- fix ptime formatstring to use %u rather than %d.
- cosmetic: log when connection is deleted on DLCX.
- change loglevels of CRCX, MDCX, DLCX events from DEBUG to NOTICE.
*) mgcp_test
- apply rename of strline_r() to mgcp_strline().
- MGCP command macros:
- Add 'I: 1' parameters.
- Use proper port numbers:
from m=audio 0 RTP/AVP 126
to m=audio 16002 RTP/AVP 128
- Change ptime to 'a=ptime:40' because this is what the MGW currently
returns. CRCX generally feed a ptime:40 and this is expected to be
returned.
- struct mgcp_test: Use only one ptype, there are no explicit BTS and NET
endpoints anymore.
Hence remove one column from tests[].
- test_messages():
- Enable: remove '#if 0'
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway.
- remove endpoint init, now done internally.
- add false asserts in error cases.
- test_retransmission():
- remove endpoint init, now done internally.
- add false asserts in error cases.
- test_packet_error_detection():
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway. Use arbitrary conn ids (e.g. 4711).
- remove endpoint init, now done internally.
- add false assert in error case.
- Assert that a conn really vanishes on DLCX, previously the conn would
remain and just be unused, now it is actually discarded.
- test_no_cycle()
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway. Use arbitrary conn ids (e.g. 4711).
- test_no_name()
- Enable: remove '#if 0'.
- remove endpoint init, now done internally.
- add false assert in error case.
- mgcp_test.ok: adjust expected results to status quo:
- We now see two dummy packets instead of one, now sent to both sides because
we don't know of BTS or NET side. (maybe drop dummy packets later...)
- packet duration, conn mode: now sane defaults show instead of unset.
- various whitespace and formatting changes from lindent.

This a cosmetic commit, copying libosmo-legacy-mgcp to libosmo-mgcp and
osmo-bsc_mgcp to osmo-mgw 1:1 at first, to provide a basis for next patches

Until osmo-msc and osmo-bsc are adjusted to operate with the new code, we will
keep the legacy code alongside the new code. The legacy code might be dropped
later.

These either remain from openbsc.git or slipped in while applying recent

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.

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

A number of the GSM timers (including T3109) had no reasonable
default values if not specified in the VTY / config file. Together
with unconditional writing to the config file, this created
config files with a persistent setting for important timers as '0'.
To make things worse, many of our example cofig files suffered from the
same problem.
Let's avoid this from happening by
* having reasonable defaults if nothing specified in the config file
* conditionally savingg timers only if they differ from default
* reject any timer values that state zero during start-up (see previous
commit)

For the vty tests, add osmo-sgsn-accept-all.cfg (that does not need an HLR) and

This helps in providing 3G software packages for the sysmoNITB hardware, which
uses 10.23.24.1 for SGSN and 10.23.24.2 for GGSN.
However, in order to not break the python tests, the osmo-sgsn.cfg example
still uses 127.0.0.1 as local address.
Change the GGSN address to 127.0.0.2, because SGSN and GGSN cannot co-exist on
the same address (the GTP port number is fixed by spec: no IE to communicate a
differing port, so it has to be the standard GTP port for both).

Original libvlr code is by Harald Welte <laforge@gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>.
This is a long series of trial-and-error development collapsed in one patch.
This may be split in smaller commits if reviewers prefer that. If we can keep
it as one, we have saved ourselves the additional separation work.
SMS:
The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.
If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.
There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.
This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.
Introduce gsm_subscriber_connection ref-counting in libmsc.
Remove/Disable VTY and CTRL commands to create subscribers, which is now a task
