The support has been implemented for an old model, we were told that
newer versions would be made incompatible with OpenBSC. Ther are
various warnings in the code and coverity has found some new ones.
Just remove the code as we don't know of anyone using this code.
The message was corrupt at several points. They are fixed now and
successfully tested.
A default T3122 timer value of 10 is defined by default now. If set to 0,
the reject message will not be sent. Note that when using existing configs
with T3122 value set to 0.
For short IP failures we want the RF to stay up and wait for
the re-connect but in case the A-link is gone too long it is
good to switch off the RF and wait for commands to enable it
again.
libcommon: Default to 30min location update period
libbsc: Limit VTY value for periodic update and disallow the value 0
According to GSM 04.08 Table 10.5.33 "The value 0 is used for infinite
timeout value i.e. periodic updating shall not be used within the cell."
This was the default value until now, but the code that deals with
expiring inactive subscribers in the next commit can't handle that case
so this remains a TODO for now.
gcc does not really know the _NR_OF_ELEMENTS_IN_ENUM approach, add
the _NUM_GSM_BTS_TYPE to the handled cases.
gsm_data.c: In function ‘gsm_set_bts_type’:

so far, osmo-bts/sysmobts used to be entered as "sysmobts" type in the
configuration file. However, there are some differences in the
protocol/behaviour and we should reflect that by a new BTS plugin (with
lots of code reuse from the nanobts driver).
We want to have multiple MSCs but we also have some data
that is only present on a per BSC basis. Right now the
MSC data is not allocated with talloc, so we have some
change in the talloc contexts.
Assume nothing special needs to be done for the Nokia
*site hardware.

Move the regexp parsing code from the NAT to libcommon as it will
be used by the NAT and BSC code. This also adds the #include <regex.h>
include to gsm_data. This header should be split up.
The daemons set up nanoBTS and HSL femto sockets by default, ie. the
three sockets to support these two drivers are open even if we have
no BTS of that kind.
This patch enables on-demand socket creation, ie. we only enable them
if we have one BTS at least that requires it.
I added two new attributes to the gsm_bts object, they are:
* the start() function includes the code that we need to run to start
the BTS. This new function contains the socket creation in the
particular case of nanoBTS and HSL femto.
* the started boolean, which is used to know if we have already
started the BTS, ie. we have already invoked start().
Note that, I have splitted the bts_model_*_init() function into two
functions, the _init() functions that register the BTS driver
and the _start() functions that start BTS driver on-demand.
While I was at it, I added several changes/cleanups to this patch:
* Group all bts_model_*_init() calls into one function bts_init(),
which is called in the initialization path of osmo-nitb and
osmo-bsc.
* Add openbsc/bss.h that contains the declaration of
bsc_bootstrap_network, bsc_shutdown_net and bts_init.
* Add missing e1inp_init() in osmo-bsc.
* Fix missing declaration of hsl_setup in openbsc/e1_input.h
Be able to configure a list of destinations (duplicates allowed)
that will be tried in a round robin fashion. The change is in
the bsc_msc_connection to operate on a list. We achieve the
round robin nature with the same trick used in the paging code
to delete and append the current entry. The nat code was updated
to compile but one can only configure one destination.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

The HSL Femtocell seems to be a poor man implementation of the
ip.access Abis/IP protocol, but cutting corners wherever possible.
We try to workaround those corners wherever possible...
