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 ef022783c3 gsup client, gsup_test_client: move logging to DLGSUP category
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.

Make sure everything is named gsup_client_ / GSUP_CLIENT_.

Rename static gsup_client_send() to client_send() to avoid clash with public
gprs_gsup_client_send() being renamed to gsup_client_send().

This is in preparation for moving gsup to libcommon, which is in turn
preparation for libvlr. libvlr and osmo-sgsn will use the same GSUP client
code. A number of patches will follow up on this, also for the the OAP client.

Neels Hofmeyr 8825c69409 Fix TCH/F_PDCH: no need to check ts subslots for PDCH
For TCH/F_PDCH in PDCH mode, directly return the lchan to use, in order to
switch it to TCH/F. To check the pchan type in chan_alloc.c, make ts_pchan()
public in gsm_data_shared.h.

Commit c3f72f63af broke TCH/F_PDCH, as a fallout
of setting the GSM_PCHAN_PDCH subslots number to 0. This is sane and correct,
but the chan_alloc code failed to see a ts as available if it has no subslots.

Explanation:

_lc_find_trx() checks each timeslot. For normal, static TCH timeslots we
determine the number of logical subslots contained and check whether one of
them is free. For dynamic TS, we can do the same when in TCH mode, but when in
PDCH mode, we already know that it is available for immediate switchover for
voice and hence can return it right away. TCH/F_TCH/H_PDCH already has a
special check for that. TCH/F_PDCH doesn't, but this worked for TCH/F_PDCH as
long as ts_subslots() returned 1 for PDCH: the for-loop at the bottom of
_lc_find_trx() checked one subslot, which succeeded on an lchan in PDCH mode,
since PDCH lchans are always marked type == NONE and state == NONE. Now we more
accurately acknowledge that a PDCH timeslot has zero subslots and that a
dynamic timeslot in PDCH mode can always be switched to voice immediately,
without checking lchan type or state.

So, above mentioned commit set PDCH to zero subslots, and the for-loop to check
the (zero) subslots never ran and hence never returned the lchan. This fix adds
a special condition for TCH/F_PDCH in PDCH mode, same as TCH/F_TCH/H_PDCH.

(Todo: ts_pchan() can probably be used in other places as well to remove some
code dup. Leaving that for another patch.)

grained time zone settings, it should probably be tied to the LAC.

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.

bsc_hack.c: drop the comment that says about the VTY init: "This needs to
precede handle_options()" -- it is not accurate. Actually move the
handle_options() above both vty_init() and the bsc_network_alloc() calls, to be
able to decide which mncc callback to pass to bsc_network_alloc. It would make
sense to set this later on, but that would require further refactoring of the
bsc_network_init() and gsm_network_init() signatures, so not in this patch.

For patch clarity, keep some code dup to be removed in a subsequent patch. In
the same sense don't change the fact that mncc_sock_init()'s return value is

The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY,
and a future patch will "hide" that global in a vty .c file. In a nutshell, I
want to

- first allocate a gsm_network,
- then initialize the VTY passing the gsm_network pointer,
- and then read the config file using the initialized VTY.

So far, bsc_bootstrap_network() allocates the gsm_network and reads the config
file right away, which only works by sharing the extern bsc_gsmnet pointer,
which I would like to uncouple.

Neels Hofmeyr eb52aad198 IuPS: properly update ra_id on GMM Attach Request
For new MM contexts, the ra_id was correctly obtained from the ue_ctx, but in
case an MM ctx is re-used and the ra_id changed, the new ra_id was not copied
to the MM context; instead, the ra_id was overwritten with uninitialized data.

Always initialize the local ra_id variable from the ue_ctx->ra_id for Iu
connections; it is used further below to update the ctx->ra_id.

For the case of a brand new Iu MM ctx, the ctx->ra_id then gets initialized a
second time. We could technically drop the init in sgsn_mm_ctx_alloc_iu(), but
it doesn't hurt either way.
