The sequence number was read from the wrong place and then
the wrong byte order conversion routine was used so we ended
up wirting 0x00, 0x00 into the patched sequence number. Add
a testcase for that.

It took me a long time to figure out that errx just exits and
the test output didn't indicate that the application was exited
early. Use a printf and good old abort in case of a failure.

Separate the test from the code necessary for the setup. This is
somehow inspired by the PhExample framework of Pharo.

An empty log_info is not enough. We need to make sure that at least
DLGLOBAL is present. Instead of doing that make sure that we have
enough entries.

When the command was added it was not verified that. Add a very
basic MGCP VTY test and test that the string appears in the config.

Currently the terms 'Routing area code' (RAC) and 'Location area
code' (LAC) are used in several places where 'Routing area
identification' (RAI) or 'Location area identification' (LAI) are
meant in fact.
This patch replaces RAC/LAC by RAI/LAI and 'code' by 'identification'
at these places.
Note that RAI := MCC MNC LAC RAC, and LAI := MCC MNC LAC (see GSM
03.03, sections 4.1 and 4.2).

Currently, if there is no SDP data in the MGCP message received from
the net, the fields containing audio encoding information are not set
in net_end. So in recvonly mode transcoding would not be set up
correctly.
This patch changes the implementation of the code handling CRCX and
MDCX to use the codec signalled in the MGCP local connection options
(field 'a:') if there isn't any SDP data. This is only halfway
negotiation, because the codec is used blindly and not matched
against the supported ones.

The code currently uses an encoded sequence of (hex) 10 20 30 40 50
60 as RAI, for which no bijective mapping to the set of
representations MCC-MNC-LAC-RAC exists.
This patch changes the hard-coded RAI to 11 22 33 40 50 60 which maps
to 112-332-16464-96 (and vice-versa).

In ae1997248ccb4fba1394267d3051082dfd85448a the handwritten tokenizer
was replaced with strtok_r. As part of this change the structural
checking of MGCP parameters was stopped. This means that a code like
"line + 3" might access beyond the first NUL and be possibly behind
the msgb. Manually add size checking again. Manually jumping to the
error label is not possible anymore as it has been removed. The result
is that invalid lines will be skipped. This is matching the general
approach by the IETF RFCs to be permissive in data being received.

This patch adds the voice muxer. You can use this to batch RTP
traffic to reduce bandwidth comsuption. Basically, osmux transforms
RTP flows to a compact batch format, that is later on decompacted
to its original form. Port UDP/1984 is used for the muxer traffic
between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This
feature depends on libosmo-netif, which contains the osmux core
support.
Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using
the vendor-specific extension X-Osmux: on) coming from the BSC-NAT,
so you can selectively enable osmux per BSC from one the bsc-nat.cfg
file, so we have a centralized point to enable/disable osmux.
First thing you need to do is to accept requests to use Osmux,
this can be done from VTY interface of osmo-bsc_nat and
osmo-bsc_mgcp by adding the following line:
mgcp
...
osmux on
osmux batch-factor 4
This just initializes the osmux engine. You still have to specify
what BSC uses osmux from osmo-bsc_nat configuration file:
...
bsc 1
osmux on
bsc 2
...
bsc 3
osmux on
In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does
not have osmux enabled.
Thus, you can selectively enable osmux depending on the BSC, and
we have a centralized point for configuration from the bsc-nat to
enable osmux on demand, as suggested by Holger.
At this moment, this patch contains heavy debug logging for each
RTP packet that can be removed later to save cycles.
The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that
is received to configure an endpoint.

This is only useful for small networks. List the IMSI and MSISDN

Sadly there is no proper foreign key relationship on the tables
that related to the Subscriber. This means we can't use a DELETE
with Cascade and need to delete everything by hand. To make things
worse maybe the SMS/Paging code is still using the subscriber
making the operation more dangerous. I had added NULL checks for
sender_id/receiver_id at 30C3 so we should not crash in this
situation.

The test has been manually verified. Executing the select for
the subscribers showed:

it authorized.

Each RP-DATA should have a unique msg reference. Currently 42 is
used for all of these. Remember the last reference we used and
increment it on the next SMS. Do not track if the reference is
still in use a clash is a lot less likely now. First unless SMPP
is used only one SMS is delivered at a time, second the transaction
space is a lot smaller than the one for the reference.

With the current multiplication we might end up with 19999 as
time on i386. When we round it ends up as 20000 on i386 and
should work the same on AMD64.
|
|
On AMD64 we had a difference in the test result most likely due
the bigger size of integers.
|

Should fix on AMD64:

So far, the jitter computation has been based on output timestamps.
This patch uses the input timestamps instead and resets jitter
computation on SSRC changes.
Sponsored-by: On-Waves ehf

Currently, when the SSRC changes within a stream and SSRC fixing is
enabled, the RTP timestamp between the last packet that has been
received with the old SSRC and the first packet of the new SSRC
is always incremented by one packet duration.
This can lead to audio muting (at least with the nanoBTS) when the
wallclock interval between these packets is too large (> 1s).
This patch changes the implementation to base the RTP timestamp offset
on the wallclock interval that has passed between these two packets.

Currently micro-secs and RTP rate get mixed when the transit value is
computed in mgcp_patch_and_count().
This patch changes get_current_ts() to accept the desired rate as
argument and to use it for the time conversion instead of always
converting to microseconds. If microseconds are needed,
get_current_ts(1000) can be used.
The arrival_time is now measured in 1/rtp_end->rate seconds so that
it can be directly compared to RTP timestamps as required by RFC3550
(section 6.4.1, see definition of 'interarrival jitter').

Currently the stats (jitter, transit) cannot be checked properly,
since they depend on the wallclock time.
This patch fakes clock_gettime (CLOCK_MONOTONIC) to reflect the
scheduling time of the RTP packets. In addition, the RTP statistical
value are written to stdout.
A RTP test case with a SSRC change along with a reference time delay
has been added.

Currently the conn_mode and the output_enabled flags are printed to
stdout.
This patch modifies this to print the output_enabled flags to stderr
instead. The bits in conn_mode are shown as RECV, SEND, and LOOP.
This does not reduce the significance of the test, since there is an
assertion already that verifies the values of the output_enabled
flags with respect to the conn_mode.
