This involves removing the openbsc_vty_print_statistics() from
vty_interface_layer3.c, as this would link across the MSC/BSC border.

The aim is to allow osmo-cscn to pass its own root talloc context and
global gsm_network struct instance cleanly. This may stir up some old and
dusty globals, but I hope it's for the better, since not all is a BSC.
To ensure that a global gsm_network pointer for the bsc_vty is set, have it as
argument to bsc_vty_init(). The vty configuration commands are added only after
bsc_vty_init(), which are needed to configure the network struct. So split up
the bsc_bootstrap_network() function into bsc_network_init() to allocate a
gsm_struct, and bsc_network_configure() to read the config file once the vty
commands are in place. In this way, no global bsc_gsmnet pointer is needed for
the bsc vty. The atomic super glue is dissolved and osmo-cscn will be allowed
to have a different name for it.
Admitted, it's still called the bsc_vty, but a split thereof is probably coming
soon, because the CSCN doesn't want any of the BSC nor BTS specific vty
commands.

The diff between this and master will probably need a lot of review and fixes.
The current state does compile, but I expect pretty much everything to be
broken now. Future development will reinstate proper functionality piecemeal.
The first goal is to get basic signalling to work, then SMS. The voice control
(RTP) is completely disabled now (see "#if BEFORE_MSCSPLIT") and will be fixed
last AFAICT.

For debugging it is nice to know how many requests are
pending. Simply count it and print it besides the paging
part.

In case foreign simcards are used we can not do authentication
and ciphering. In case a TMSI is re-used too early and we do
page using TMSI we can't know which of the two MS is responding
to us. We could change the "secure channel" routine to ask for
the IMSI and only then stop the paging.
As we don't have ciphering there is not much use in using the
TMSI. Add a mode "no assign-tmsi" that will not assign the TMSI
during LU. Now CM Service Request and Paging Response will
work using the IMSI. There can't be a clash with that.

The idea of "subscriber_get_channel" was that different
requests would be coordinated. At the same time we have
seen that the "queue" can get stuck at both 31C3 and the
rhizomatica installations.
Voice calls and SMS do not need coordination. We should
be able to send SMS on a voice channel and switch the MS
from a SDCCH to a TCH in case we establish a voice call.
The SMS code itself needs to coordinate to obey the limit
of one SMS per direction but this should be enforced in
the sms layer and not on the subscriber.
Modify the code to have a simple paging coordination. The
subscriber code will schedule the paging and register who
would like to know about success/failure.
This allowed to greatly simplify the paging response
handling for the transaction code (and in fact we could
move the transaction list into the subscriber structure
now). The code gained to support to cancel the notification
of a request (but not the paging itself yet).
TODO: Cancel paging request in case no one cares about it
anymore.
|
|
Over the next commits the queuing of commits will be
completely modified to remove the queue and move the
scheduling/limits to the outer callers.

Currently some VTY command do neither check the length of the source
string before calling strncpy nor ensure NUL-termination afterwards.
This can to destination string buffers whose contents are not
NUL-teminated.
This commit adds checks and corresponding warnings to the VTY
commands 'subscriber TYPE ID name .NAME" and "subscriber TYPE ID
extension EXTENSION".

Document the parameters that can be passed on.

Introduce a NITB node and add the subscriber creation as
config name in there.
|
|
Move the "logging filter imsi IMSI" into the BTS/NITB code to
allow to set the gsm_subscriber and only compare it. This way
we simply compare the subscriber address and don't have to care
if the subscriber data is still valid.

This extends osmo_nitb to offer a UDP feed of real-time measurement
reports, which can be used by (a variety of) external tools for
visualization or other processing.
We also add a small ncurses based tool (meas_vis) which shows a
baragraph display of the last few mobile stations that were active,
indicating their uplink/downlink receive level and quality.
<WARNING>
This sends non-portable structures like gsm_meas_rep over UDP
and assumes the receiver has identical alignment and endianness! Before
this feature is merged, it either needs to be converted to a unix domain
socket (but they don't do multicast, which would be nice) or the wire
format needs to change into something portable with defined alignment
and encoding
</WARNING>

Currently every subcriber object directly refers to the gsm_network
which contains a flag shared by every related subscriber
(keep_subscr). This adds a dependency on gsm_network even if only the
function defined in gsm_subscriber_base.c are used.
This patch adds a new struct gsm_subscriber_group which contains the
keep_subscr flag and a back reference to the network object. The
latter is not dereferenced in gsm_subscriber_base.c, so it can safely
be set to NULL when only that part of the gsm_subscriber API is being
used. It also changes that API to use gsm_subscriber_group instead of
gsm_network parameters.
Since there are some places where a pointer to the gsm_network is
needed but where only a gsm_subscriber is available, a 'net' back
pointer is added to the group struct, too. Nevertheless subscr group
and network could be separated completely, but this is not the topic
of this commit.

openbsc_vty_print_statistics will already print these counters

Remove ournode_exit_cmd, ournode_end_cmd, and bsc_install_default()
since this functionality is provided by the current libosmocore.
Replace calls to bsc_install_default() by call to
vty_install_default() with the following semantic patch:
@rule1@
expression N;
@@
- bsc_install_default(N);
+ vty_install_default(N);

The database code should not know about the network. Move the
setting of the network pointer into the subscriber layer.
|
|
It may be useful in production, but it's really required for
VTY testing of subscriber related commands.
|

Add bsc_install_default() and replace all install_default()
This patch adds bsc_install_default() which calls install_default()
and add 'exit' and 'end'. All other calls to install_default() are
replaced by calls to bsc_install_default().
Since 'exit' and 'end' are now added automatically to each node, the
explicit registrations of these commands are removed by this patch,
too.
The related tests succeed now without work-arounds (except for the
'config' node itself which is part of libosmocore).

Katerina pointed out that some nodes are not fully documented and
proposed some messages. The token/timeout messages were correct, I
have modified the other messages. I removed the full-stop from the
PING/PONG documentation as we are normally not using a full sentence.

when the SMS code was moved into libosmocore, its logging prefix was
changed from 'sms' to 'lsms', which breaks existing config files.
This introduces a deprecated/hidden vty command to make sure those
config files are still parsed OK, and will simply print a warning
message about the config needing some update.

Some nodes below 'config' didn't have ournode_exit / ournode_end,
and thus were not able to properly perform this function. exit should
always only go back one level, while end drops us back to ENABLE_NODE.
The prompt now represents the nesting level, and there's one consistent
space after the final prompt character (typically #).

Change "pending send" to "pending-send" as there is no other pending
command right now, add missing documentation for parameters.

In order to have the MNCC application reliably decide on the codec type,
it needs to know if we are running on a TCH/F or TCH/H. Thus, we pass
lchan_mode as a new parameter to the 'struct gsm_mncc'

This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.

This patch adds several messages that would be displayed if:
* the Ki argument is missing.
* you pass an invalid Ki.
* the database fails to perform the operation (add/delete/update).
Before this patch, no messages were spotted on this errors.
I noticed this while adding Ki to the existing subscribers in the
nanoBTS setup: I introduced a wrong Ki but the VTY command line did
not report any error. A quick look at the database via sqlite
command confirmed that the new authkey information was not added.
