Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming
in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but
also for libvlr to decide between GSM or UMTS Auth.
Until actual Iu support is merged to master, this indicator will aid VLR unit
testing.
At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to
clearly distinguish the names if we want to add it, explicitly name the ones we
have RAN_GERAN_A and RAN_UTRAN_IU.

Remove the fuzzer interface that was partially implemented in
gsm_04_08.c and silent_call.c is causing problems when an
SMS is sent during an active silent call. The reason for this
is that gsm0408_dispatch() in gsm_04_08.c would decide to
rout all uplink traffic to silent_call_rx() in silent_call.c.
silent_call_rx() is a stub function that discards the data.
This patch removes the fuzzer interface code by placing ifdefs
around it, so that it can be re-activated by experimentators.

Similar to a recent patch in osmo-python-tests for VTY based tests, but this is
for the Ctrl tests.
The TestCtrlBase tests gave a constant sleep(2) grace period for the process to
startup. This causes tests to take minutes for no reason at all.
Add code to TestCtrlBase to try and connect right away, retrying up to three
seconds in .1 second intervals. This flies through most tests without any
sleep() at all.

If a pdp context is created a xid request is sent right after
the pdp-context-ack message. The sending of the pdp-context-ack
and the xid message is triggered from the GGSN via the GTP
interface.
When the pdp-context-ack message is not received by the MS, it will
send the pdp-context-request again. A lost pdp-context-ack is resent
by the SGSN directly so that the mechanism described above does
not work for pdp-context-ack resents.
This commit adds code to trigger the sending of xid messages also
for resent pdp-context-ack messages.

On 'auth-policy remote', the SGSN requires GSUP server address and port. If it
was missing, the SGSN would print a VTY warning and run anyway. Make this error
more fatal: print an error (flattened a bit) to stderr and abort the program.
Move validation of the GSUP server data presence out of the VTY command itself
and into the config reading function. This way the GSUP server config can be
given anywhere, including below the auth-policy config (was required above).
Don't care about setting the auth-policy to remote with a telnet VTY, because
in that case the GSUP client won't be started anyway.

To be paranoid, catch a NULL subscriber and/or bts in
subscr_update_expire_lu(): print an error log and avoid segfault.
(I'm not sure this would really happen in a normal situation.)
During aggressive testing of Paging timeout, I came across this segfault in
msc_release_connection() when conn->expire_timer_stopped is set but
conn->subscr is NULL, at the subscr dereference after:
if (conn->expire_timer_stopped)
subscr_update_expire_lu(conn->subscr, conn->bts);
I brought this situation about by a fabricated Paging fault, i.e. in
gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at
all. Thus conn->subscr is still NULL when expire_timer_stopped is 1.
When looking at CM Service Request handling, the conn->subscr is set before
setting expire_timer_stopped = 1, which is a saner thing to do. But without my
mad 'return 0', there is in fact no way to have a NULL subscriber there.
It looks like all other code paths already do the same, but it's not that
obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of
NULL conn->subscr, and while at it catch NULL bts as well.

gsm0408_rcv_cc() dereferences many conn members without checking presence: the
bts and lchan members may be expected to be NULL in the ongoing MSC split and

But the conn->subscr is initially NULL, so an MS sending a CC message before

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)

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.

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)

Enable Deactivate PDP context based on the IMSI of the subscriber.
When there are PDP contexts present for a MM context,
PDP context will be deactivated along with GMM Detach(MM context deletion).
If there are no PDP present, MM context will be deleted to avoid
further PDP context request from the MS.
Test cases is added to check this functionality.

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.)

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).

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.

Now that bsc_network_alloc() is separate, move it to before the VTY init (a
subsequent patch will pass the gsm_network instance as a parameter to
vty_init()).
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.
Change-Id: Ie6a7037e703b5a2d08ceeb20d35f197aaddc9d1b
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
ignored.
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.

libbsc and libmsc will have separate subscriber connection structs. Hence don't

Future: this will be used by libmsc's subscriber connection, for osmo-cscn.
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.

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.

Coverity scan detects a Null pointer deref (FORWARD_NULL) in
gprs_sndcp_comp.c: 67 in gprs_sndcp_comp_create().
The reason for this is that gprs_sndcp_dcomp_init() and also
gprs_sndcp_pcomp_init() rely on the comp_entity->algo algo
flag. If the program logic is correct a null pointer deref
should never occur.
This commit adds OSMO_ASSERT() statements to ensure a null
pointer deref is catched if if the ...comp_init() functions
are used with incorrect parameters.
