Philipp Maier b4999b60d4 pcu_sock: add basic pcu interface support
Adds a basic version of a pcu socket interface, similar
to the one that can be found in osmo-bts.

Neels Hofmeyr 6d804b1a7e add struct bsc_subscr, separating libbsc from gsm_subscriber
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will
not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC
subscriber: struct bsc_subscr.

Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no
longer have a backpointer to gsm_network (used to be via subscr->group).

Create a separate logging filter for the new BSC subscriber. The implementation
of adjusting the filter context is added in libbsc to not introduce
bsc_subscr_get/_put() dependencies to libcommon.

During Paging Response, fetch a bsc_subscr from the mobile identity, like we do
for the gsm_subscriber. It looks like a duplication now, but will make sense
for the VLR as well as for future MSC split patches.

Naming: it was requested to not name the new struct bsc_sub, because 'sub' is
too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function
prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to
match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast
to type, relatively short, unambiguous, and the naming is consistent.

Add bsc_subscr unit test.

Neels Hofmeyr 43273c63de factor out gen of USSD notify and release complete to libosmocore
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and
gsm0480_send_releaseComplete() functions, since there will be distinct
subscriber connection structs.

Rename to msc_send_ussd_notify() and msc_send_ussd_release_complete(), and add
the same in libbsc with bsc_ prefix in new file gsm_04_80_utils.c.

In preparation of this patch, the message generation part of these functions
has been added to libosmocore as gsm0480_create_ussd_notify() and
gsm0480_create_ussd_release_complete(). Use these.

Adjust all libmsc and libbsc callers according to use the msc_* or bsc_*
implementation, respectively.

Philipp Maier b4cb838092 OML: Improve OML attribute handling
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

Neels Hofmeyr c5e75f3e6a dyn TS: Rename bsc_dyn_pdch.c to bsc_dyn_ts.c
It's no longer just for IPAC style TCH/F_PDCH, but also contains code for
TCH/F_TCH/H_PDCH, so pick a more general name.

Neels Hofmeyr b8afb5fda2 dyn PDCH: send PDCH ACT for each TCH/F_PDCH on TS Enable
Add dyn_pdch_init() in new file bsc_dyn_pdch.c (new file to avoid linking
issues; bsc_init.c would create undefined references, and putting in a new file
is the easiest solution).

Call dyn_pdch_init() from nm_statechg_event() whenever a TS is enabled.

Revert the |= TS_F_PDCH_MODE chunk from previous commit, since this flag will
now be set after dyn_pdch_init() sent out the PDCH ACT and when subsequently
the PDCH ACT ACK messages are received in rsl_rx_pdch_act_ack().

Jacob Erlbeck 3911880b68 bsc: Move gsm_subscriber_base.c to libcommon
Since it is planned to use struct gsm_subscriber to manage subscriber
data in the SGSN, this file which contains the generic subscriber
related methods is moved to libcommon.

Jacob Erlbeck cdd4302c6d bsc: Move gsm_network_init function to libbsc
Currently libcommon depends on libbsc, because gsm_network_init
(libcommon/gsm_data.c) directly calls gsm_net_update_ctype
(libbsc/gsm_04_08_utils.c).

This patch moves gsm_network_init to a new file libbsc/net_init.c.

Holger Hans Peter Freyther f0167ddfc2 hsl: Remove the support for the HSL bts from OpenBSC
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.

Holger Hans Peter Freyther 511f9c3e4a si: Partially implement the range encoding for the SI.
I saw the old copy of the "Appendix J" code too late and I have
discovered some quirks and I am more familar with my implementation.
Most noticable 'w' only needs to be as big as the input arfcn but
requires the 'w' to be initialized. The power_of_2 implementation
differs as well (mine matches the output of wirehsark).

The f0 could be chosen in a better way but right now picking
the lower bound is the easiest. It is not clear if to use
modulo if the range is chosen in the middle. This can be improved
in the future. Right now I have no bit fiddling for range128, 256
and 1024 as I was running out of time.

Harald Welte f383aa11a5 BSC: introduce new "sysmobts" BTS model
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).

Pablo Neira Ayuso 0d2881ad58 bsc: on-demand setup of nanoBTS and HSL femto sockets
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

We try to workaround those corners wherever possible...
