GSM 12.21 specifies that "No elementary procedure shall be
initiated to an object instance which has not yet replied to
a previously initiated elementary procedure with a response,
an ACK or a NACK within a layer 3 time-out. The layer 3
timeout for ACK, NACK and responses shall have a default value
of 10 seconds."
We are using this flag in the BTS to enforce/safe-guard
this situation.

Rename this function to bsc_send_ussd_no_srv() since it's a rather
specialised function and not a generic USSD notification function.

The MS do not show the USSD messages yet. This patch modifies the
implementation to insert a CM Service Accept to finish the
establishment of the MM connection according to 3GPP TS 04.10/3.2.1
before the USSD notification is sent.
This fix has been tested with a Blackberry phone that has shown
an ussd_grace_txt after rf_locked has been set to '1'. Without this
patch, that message wasn't shown. The phone has sent a CC Setup
and other messages before processing the channel release message sent
by the BSC, but these messages have not been forwarded to the MSC (as
expected).

These functions are currently located in libmsc/gsm_04_08.c together
with other symbols that (transitively) depend on many external
symbols (and thus libraries) that aren't otherwise needed by e.g.
osmo-bsc.
Since gsm48_tx_mm_serv_ack() will be needed by osmo-bsc, these
functions are moved to avoid the dependency on gsm_04_08.o.

This reverts commit 61bd965b04e4f00eaf4196eebb4ec6269926d551.
No, we should not link to dbi.. and these libraries..

This patch replaces the calls to ignoredCheckForEndAndExit by calls
to checkForEndAndExit to test the libosmocore nodes, too. The former
method is removed.

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);

When the PCU is activating a channel we don't want to tell the
BSC using RSL. Add a flag so we can keep track of who asked for
the activation/release of the channel.

The gbproxy looses NSEI changes on BVC_RESET and then tries to send
later messages to the wrong (not longer existing) destination.
This patch fixes this by updating the peer's nsei field on BVC_RESET.

This checks the behavior of the gbproxy when the BSS peer changes the
NSEI and the NSVCI. It also tests BVC_RESET and other UNITDATA
messages after these changes between BSS and SGSN and vice versa (via
the gbproxy).

This adds the option to delete all BVC peers and/or NS_VC with a
given NSEI with a single command. Static (configured) NS-VC are not
affected. In addition, all connections for this NSEI that can be
deleted by this command can be listed without deleting them by
appending 'dry-run' to the command.

This just deletes the peer entry based on NSEI and BVCI. The NS-VC
are not touched.

This also frees the counter group pointed to by peer->ctrg when the
peer gets freed.

Currently such messages lead to a creation of a new peer with the
SGSN's NSEI, which results in echoing the message back to the SGSN.
This patch modifies this by sending a STATUS response (invalid BVCI)
instead back to the SGSN.

This adds a test with a UNITDATA SGSN message that is addressed to an
invalid (unknown) BVCI. The test shows, that the message is echoed to
the SGSN.

This adds counters that are incremented when errors are detected.
It also modifies the VTY command 'show gbproxy' so that
'show gbproxy stats' shows the counters.

Add the unused attribute to peer_free() that isn't used currently.
Change 'RAC' to 'NSEI' in the log message, since the latter has been
examined before the log message is generated.

This adds a simulation of the SGSN side of the Gbproxy. The VC is set
up correctly and several combinations of BSSGP messages are sent.

Currently in most places in gb_proxy.c a reference to a NS-VC object
is used where the peer is meant instead. The patch changes this by
using the NSEI instead in these cases.

This program tests the gbproxy implementation by passing NS messages
to a modified gbproxy that dumps the resulting messages, signals, and
state.
It focusses on testing abnormal situations like port changes.

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.

Funny, this is a correct C expression and doesn't change execution, thus it

This adds a per BTS control command 'timezone' which expects a value
of the format '<hours>,<mins>,<dst>' or 'off' to set the value of
bts->tz. It has the same functionality like the existing VTY command
'timezone' in network/bts.

This adds in-place patching of the time information in the
MM INFORMATION message. The timezone in the 'Local time zone' and
the 'Universal time and local time zone' information elements
and the offset in the 'Network Daylight Saving Time' information
element are optionally set.
The new values are determined by the 'timezone' vty command in the
config_net_bts node. That command is extended by an optional
DST offset parameter.
Tests are provided for the vty part and for the plain
bsc_scan_msc_msg() function.

When verification failed and the reply string was not updated, the
message "Someone forgot to fill in the reply." was shown instead
of the default "Value failed verification." message.
This patch changes the default reply handling in ctrl_cmd_handle()
by setting the reply to NULL initially and then checking it at the
end. If it hasn't been set, a generic message is assigned and an
error is logged.

This script is similar to vty_test_runner.py but tests the control
interface instead.
It currently tests some error cases, BTS status queries, and
setting/clearing rf_locked.

Based on the feedback of Peter from the mailinglist, move the

This stores the last SET rf_locked control command along with a

this information.

This prevents the application from crashing when there is a half

Send an USSD message to the mobile station requesting a connection
for a call or a SMS when the link to the MSC is down or in the
grace period.
The messages can be set (and this feature activated) by setting
bsc/missing-msc-text resp. msc/bsc-grace-text via the vty.
The generation of both messages has been tested manually.

In case of the RLSD coming from the MSC we are patching the address
in-situ but for local calls set con = NULL. We then answered the RLSD
with the wrong reference and the MSC kept on trying.
