Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.
API osmo_stats_vty_add_cmds never had a param list but has seem problem
(no "void"), so some users decided to pass a parameter to it.

Currently the force_realloc feature is turnd on and of in a
hardcoded way. This patch makes the option available via VTY.
Backport from osmo-mgw.git.

Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores
parameters to log_vty_command_* functions. Hence parameter of
logging_vty_add_cmds() is ignored too. As we depend on much later
libosmocore version anyway, we can simplify code somewhat by removing
parameters which will be ignored anyway.

After libosmocore 55dc2edc89c1a85187ef8aafc09f7d922383231f which outputs
'telnet at <ip> <port>' from telnet_init_dynif(), there's no need to log the
telnet VTY bind here anymore.

In gsm_lchant_name(enum gsm_chan_t), use the gsm_chan_t_names value strings
from libosmocore instead of redefining the same strings. The list from
libosmocore is also more complete, including CCCH and PDTCH.
Add a todo comment to move to libosmocore.
In consequence, libosmogsm linkage needs to be added to osmo-bsc_mgcp,
mgcp_test, mgcp_transcoding_test and smpp_mirror, smpp_test.

Following the 'line vty'/'bind A.B.C.D' command added in libosmocore, use the
configured address to set the telnet bind for the VTY line. It is now possible
to publish the VTY on a specific local interface (including 0.0.0.0 aka "any").
Implement in all of:
osmo-gbproxy
osmo-gtphub
osmo-sgsn
osmo-bsc
osmo-bsc_nat
osmo-bsc_mgcp
osmo-nitb
In some of these main programs, move the telnet initialization below the
configuration parsing.
Historically, this was not a good idea for programs using bsc_init.c (aka
bsc_bootstrap_network()), since they expected a gsm_network struct pointer in
((struct telnet_connection*)vty->priv)->priv, so that telnet had to be either
initialized or replaced by a dummy struct. In the meantime, the gsm_network
struct is not actually looked up in a priv pointer but in the static bsc_vty.c
scope (bsc_gsmnet), so this limitation is mere legacy (even though said legacy
is still there in an "#if 0" chunk).
In the other binaries I have briefly looked at the init sequence dependencies
and found no reason to initialize telnet above the config file parsing. In any
case, I have tested every single one of abovementioned binaries to verify that
they still parse the example config successfully and launch, allowing VTY
connections on the configured address(es). I hope this suffices.
In all of the above, log VTY address and port. LOGL_INFO is disabled by default
in some of the logging scopes, and since it is a single log message right at
program launch, I decided for the slightly more aggressive LOGL_NOTICE.

When libosmo-netif and/or libosmo-abis are installed in distinct

Move the "logging filter imsi IMSI" into the BTS/NITB code to
allow to set the gsm_subscriber and only compare it. This way
we simply compare the subscriber address and don't have to care
if the subscriber data is still valid.

Jacob pointed out that "free_endp" refers to the memory of
the endpoint being freed. What we want is actually a way to
release an endpoint (and the resource it allocated) or in
the case of the testcase/testapp initialize the data structure
correctly. Introduce two names for that.

This patch moves the files relevant to transcoding from
src/osmo-bsc_mgcp to src/libmgcp and src/include/openbsc. Makefiles
and include directives are being updated accordingly.

The current transcoder implemenation always does a 1:1 recoding
concerning the duration of a packet. So RTP timestamps and sequence
numbers are not modified.
This is not sufficient in some cases, e.g. when the BTS does only
allow for a single fixed ptime.
This patch decouples encoding from decoding and moves the decoded
samples to the state structure so that samples can be combined or
drain according to the packaging of incoming and outgoing packets.
This patch incorporates parts of Holger's experimental fixes in
0e669e05^..9eba68f9.

This tool uses mgcp_transcode.c to convert audio data from stdin to
stdout.
Sponsored-by: On-Waves ehf

This patch implements audio transcoding between the formats GSM,
PCMA, L16, and optionally G.729.
The feature needs to be enabled by using the autoconf option
'--enable-mgcp-transcoding'. In this case mgcp_transcode.c will
be compiled and linked to osmo-bsc_mgcp, and the transcoding
functions provided will be registered as processing callbacks.
If G.729 support is required, libcg729 needs to be installed and
'--with-g729' must be passed to ./configure.

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.
|
|
So far, a single dummy packet has been sent immediately after the
reception of a MDCX message. There is no dedicated keep alive
mechanism (it just worked because the audio from the MS has always
been forwarded to the NAT until the 'mgcp: Set output_enabled flags
based on the MGCP mode' patch).
This patch adds explicit, timer based keep alive handling that can be
enable per trunk. A VTY command 'rtp keep-alive' command is added for
configuration which can be used to set the interval in seconds, to
send a single packet after the reception of a CRCX/MDCX when RTP data
from the net is expected ('once'), or to disable the feature
completely ('no rtp keep-alive'). In 'send-recv' connections, only
the initial packet is sent if enabled (even when an interval has been
configured). The default is 'once'.
Note that this removes the mgcp_change_cb() from mgcp_main.c.

This enum indicates if the mgcp is running on the BSC or the BSC-NAT.

Since automake 1.13 INCLUDES is depricates and causes a warning
|
|
Use a usec timestamp for the local time. The seconds to usec will
swap over to the lower bits but this appears to be correct. The
CLOCK_MONOTONIC is used to fulfill the RFC 3550 requirement even
if it is a bit slower than the gettimeofday.
Make sure to initialize transit in a way that the first transit
time will be 0. Otherwise the jitter will contain the difference
of the localtime and the remote time.

This allows the use of the existing "call-agent ip A.B.C.D" command in
libmgcp in order to set a default destination address of the call agent.
This is required as a pre-condition for certain call agents (like the
zynetix MSC) that require a RSIP from the BSC to the MSC as the initial
MGCP message.

Ubuntu 11.10 has changed some linker/compiler flags. Some fixes for this
can be seen here[1]. In general the to be linked libs need to be moved into
the LDADD section of parameters. This is with the old BFD linker (not gold).
This is likely to end in some ping-pong with other versions of the linker.

"vty: integration with logging framework"

It has been tested with osmo-nitb. The other just compiled tested.
