in a safe way.

Philipp Maier db142dc59d sndcp: Allow empty SNDCP-XID indications
In some rare cases the modem might send a xid indication that does
not contain anything except the version number field. The sgsn
ignors such SNDCP-XID indications by stripping the entire field
from the response. We found a modem in the wild that started to
act problematic when the empty SNDCP-XID was missing in the
response. This patch changes the XID negotiation behaviour in
a way that if a modem should send empty SNDCP-XID indications,
the reply will also contain an empty SNDCP-XID indication. Apart
from that the SNDCP-XID version number is now parsed and echoed
in the response. This ensures that we always reply with the version
number that the modem expects. (The version was 0 in all cases we
observed so far)

Neels Hofmeyr 37f9252361 oap_client: make use of OAP optional: disable for NULL config
When passing a NULL config to osmo_oap_client_init(), set OAP to disabled
state. Along with the previous fix that ensures message rejection in the
disabled state, this makes use of OAP in the GSUP client optional.

oap_client_test: expect null config to set state to disabled.

Neels Hofmeyr 73ed45599b oap_client: move logging to DLOAP logging category
Use libosmocore's DLOAP logging category for OAP.

oap_client_test.c: make sure DLOAP is in DEBUG level to not lose any logging
messages from experr.

Todo: we're using a "Library" logging category, which is not really what the
library category was intended for. Instead, the OAP client should probably be
given a logging category like DVLR or DGPRS in its initialization API.

Neels Hofmeyr 49012f14dd oap: rename public API from oap_ to oap_client_
Mainly to differentiate the OAP messaging API (osmo_oap_ in libosmocore) from
the OAP client.

This is in preparation for moving the oap client to libcommon, which is in turn
preparation for libvlr. Add the osmo_ prefix, as all public Osmocom API should
have. We also have OAP messages code in libosmocore, so clarify by naming this
osmo_oap_client, and by also renaming the oap_test to oap_client_test. This
reshuffling will allow an easy move of OAP to libosmocore if we should want to
do that. A number of patches will follow up on this.

Neels Hofmeyr 7398395cc0 Move timezone settings up to network level
Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS
structures will be available on the MSC level. To simplify, drop the ability to
manage several time zones in a core network and place the time zone config on
the network VTY level, i.e. in gsm_network. If we are going to re-add fine
grained time zone settings, it should probably be tied to the LAC.

Adjust time zone VTY config code (to be moved to libcommon-cs in subsequent commit).

Adjust time zone Ctrl Interface code.

Neels Hofmeyr 1a60644eb2 reinvent connection_for_subscr() and move to libmsc
Implement connection_for_subscr() from a completely different angle: instead of
looking up lchans in bts structs, look up the subscriber in the global list of
gsm_subscriber_connection. static lchan_find() is thus obsoleted.

All callers of connection_for_subscr() live in libmsc, so move to libmsc.

The move and edit are done in a single commit since the old and new
implementation have nothing in common.

Future: osmo-cscn will use this, without bts being present.

Remove implementation of connection_for_subscr() from channel_test.c -- it is
possible that the abort() in there was intended for a regression test, but
actually it seems the implementation was merely added for linking reasons, and
the abort() added to guard against the NULL return value: no comment nor the
commit log indicate that the abort() is test critical; the addition was the
only change in channel_test.c for that commit; at the same time a
connection_for_subscr() call was added in libmsc.

Neels Hofmeyr 05667a0aff sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counter
libbsc and libmsc will have separate subscriber connection structs. Hence don't
rely on gsm_subscriber_connection, but work on a direct pointer to the counter
for the next RP reference.

The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop
the entire file.

Neels Hofmeyr e78ae21ff4 move to libcommon-cs: net init 3: actual move
Reincarnate gsm_network_init() as the parts not specific to libbsc.
Move from bsc_network_init() those bits that are not BSC specific (and useful
for upcoming osmo-cscn).

Add libcommon-cs to all linkages that use gsm_network_init().

Note: the only requirement to allow linking gsm_network_init() without libbsc
is to keep the call to gsm_net_update_ctype() out of libcommon-cs. The other items
are kept out of libcommon-cs because it makes sense semantically. But the separation
is not strong in that the BSC specific data members are of course still
omnipresent in struct gsm_network. If bsc_network_init() is not called, these
are not initialized properly -- for now no users of uninitialized members
exist.

So this is just a first step towards a sensible split of the BSC and MSC
gsm_network structs. The long term aim should be to have entirely separate
structs with some common general items.

Neels Hofmeyr 2d521a0296 move to libcommon-cs: net init 2: move bsc_network_init decl to new .h
bsc_network_init() is more fit to live in a BSC specific header, move it to new
common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network
in the future.

Adjust header includes across the board. Particularly, fix abis_nm.h by
explicitly including gsm_data.h: it so far relied on other headers to do that,
which now is no longer always given.

Neels Hofmeyr 27681a3407 move to libcommon-cs: net init 1: rename to bsc_network_init
The gsm_network_init() function initializes a whole lot of BSC specific stuff.
Aiming to move some of it to libcommon-cs, first rename it to bsc_network_init().
This will retain the BSC specific stuff when the move is done.

Adjust all callers.

Future: osmo-cscn will call the more generic part and not the BSC specific
part.

Neels Hofmeyr c3f72f63af dyn TS: fix: ts_subslots() for TCH/F_PDCH in PDCH mode
In gsm_data_shared.c, add ts_pchan() to determine actual pchan type for dynamic
and non-dynamic TS.

Use in ts_subslots() to fix the value returned for TCH/F_PDCH in PDCH mode.
Adjust the assertion in channel_test.c accordingly.

Drop GSM_PCHAN_TCH_F_PDCH, which is now handled in ts_pchan().
Explicitly add GSM_PCHAN_PDCH as zero in subslots_per_pchan[] (cosmetic).
Adjust the comment in subslots_per_pchan[].

The fix for the number of subslots affects only one caller: bts_chan_load() in
chan_alloc.c. Before this, it would always include a TCH/F_PDCH in the
load_counter->total, now it is skipped when in PDCH mode. Whether this is the
way bts_chan_load() should handle dynamic TS is a separate discussion, so far
I'm only making sure that the two dyn TS kinds act in the same way:
TCH/F_TCH/H_PDCH is only counted when in TCH mode, and TCH/F_PDCH should match.

Neels Hofmeyr 77c8d5ffb5 mscsplit: gsm_network_init(): add explicit root talloc ctx
Decouple the root talloc context from libbsc's global talloc_bsc_ctx.

This allows to define the root talloc ctx from a main() scope, which in turn
helps decouple libmsc from libbsc.
