Previously we required pcap.h unconditionally which causes embedded
build failure because it's not included in current version of out poky
toolchain. We can add it to toolchain but it's only necessary for
utils/osmo-meas-pcap2db which is not built for sysmobts anyway so it's
easier to just make this dependency optional and build osmo-meas-pcap2db
only if it's available - similar to the way we build osmo-meas-udp2db.

The fix introduced in dac5867af5ff90d4beb70fc30a5743f60f159e3a did not
work because autotools in our OE are too old. Use alternative way to
include custom m4 macros to fix it.

It is generally not a good idea to add more and more external
dependencies unless absolutely needed. autoconf-archive is a good
example of that, as we need to update all build machines, and older
OpenEmbedded versions do not appear to have (the right?)
autoconf-archive recipe. Provide local copy of necessary m4 files to fix
the build there.
The dependency to autoconf-archive was introduced in Change-Id

This introduces a failure with ./configure on my machine:
../configure: line 6612: syntax error near unexpected token `-Werror=implicit,'
../configure: line 6612: `AX_CHECK_COMPILE_FLAG(-Werror=implicit, CFLAGS="$CFLAGS -Werror=implicit")'
Makefile:420: recipe for target 'config.status' failed
make[1]: *** [config.status] Error 2
Installing autoconf-archive did not fix the error.
So even though jenkins seems to accept this, I cannot build with this patch.
Let's find out how to do this in a way that all systems can still build
and then re-apply this patch.

Use the DLGSUP logging category for GSUP.
Bump the required version of libosmocore to 0.9.5 to benefit from the DLGSUP
logging category fix in core/logging.[hc].
(Id974c7be158e4d60421a98110f5c807aefd31119)
Todo: we're using a "Library" logging category, which is not really what the
library category was intended for. Instead, the GSUP client should probably be
given a logging category like DVLR or DGPRS in its initialization API.

GSUP was added to libosmocore in 0.9.4. We're using it here, so make up for a
previously missing bump.
(BTW: I'm pretty sure that other dependencies are also in dire need of a bump,
but leaving that for another patch)

the OML attribute tables are hardcoded. To set variable parameters,
the hardcoded data structure (tlv) is patched on byte level during
runtime. This patch replaces this mechanism.
- Replace hardcoded OML attribute tables with dynamically
generated TLV structures.
- Add unit tests to check if the OML attribute tables are
generated correctly
- Put OML attribute table generator code in a separate file:
bts_ipaccess_nanobts_omlattr.c

Add basic MM Authentication test setup, with fake DB access and RAND_bytes().
So far implement simple tests for IO error during DB access and missing auth
entry.

auth_action_str() inline function in auth.[hc].
First steps towards a new GTP hub. The aim is to mux GTP connections, so that
multiple SGSN <--> GGSN links can pass through a single point. Background:
allow having more than one SGSN, possibly in various remote locations.
The recent addition of OAP to GSUP is related to the same background idea.
(This is a collapsed patch of various changes that do not make sense to review
in chronological order anymore, since a lot of it has thorougly transmorphed
after it was first committed.)

We just link to libosmovty and if it requires crypt internally it
needs to link to that (and not us). This looks like a left-over
from when we moved the VTY code out of OpenBSC
We don't need to consume all the entropy of the kernel but can
use libcrypto (OpenSSL) to generate random data. It is not clear
if we need to call RAND_load_file but I think we can assume that
our Unices have a /dev/urandom.
This takes less CPU time, provides good enough entropy (in theory)
and leaves some in the kernel entropy pool.
c-ares is an asynchronous DNS resolver and we need it to
resolve the GGSN address. This is integrating the library
into our infrastructure. We will create and maintain a list
of registered FDs (c-ares is currently only using one of
them) and (re-)schedule the timer after events occurred.
For customer requirements we want to be able to do
filtering on the BSC as well. The same messages need
to be scanned and the same access-lists will be looked
at. In the future we might even split traffic based
on the IMSI. Begin with moving the code to a new top
level directory and then renaming and removing the
nat dependency.
The code assumes that sqlite3.h is in the standard include
path. Maybe sqlite3 wasn't installed or resides in a non
standard (/usr/local) location? Fix the build as it has been
broken since 1st of January.
./configure --help indicates:
--enable-external-tests Include the VTY/CTRL tests in make check
[default=no]
but
./configure ... --enable-external-tests
configure: WARNING: unrecognized options: --enable-external-tests
the name of the option seems to be --enable-ext-tests.
We started with only testing the VTY but now test VTY and CTRL
interface with this python framework and might even extend this
to SMPP. So add and "--enable-external-tests" directive which
enables the external interface tests.
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.
The old ipa_msg_recv() implementation didn't support partial receive,
so IPA connections got disconnected when this happened.
This patch adds the handling of the temporary message buffers and uses
ipa_msg_recv_buffered().
It has been successfully tested by jerlbeck with osmo-nitb and
osmo-bsc.

This adds in-place patching of the time information in the
MM INFORMATION message. The timezone in the 'Local time zone' and
the 'Universal time and local time zone' information elements
and the offset in the 'Network Daylight Saving Time' information
element are optionally set.
The new values are determined by the 'timezone' vty command in the
config_net_bts node. That command is extended by an optional
DST offset parameter.
Tests are provided for the vty part and for the plain
bsc_scan_msc_msg() function.
