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.

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.

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.

Ticket: OW#978
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.

Ticket: OW#978
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.
This stores the last SET rf_locked control command along with a
timestamp. The 'show network' vty command is extended to show
this information.
Ticket: OW#659
This prevents the application from crashing when there is a half
configured BTS (e.g. by using the command 'bts 1' when there isn't
a BTS 1) and the 'write' command is used.
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.
Ticket: OW#957
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.
It was possible to cause a crash by enabling and disabling the
MSC connection. The enabling lead to scheduling a connection
and the second call was not stopping the timer.
Assign a static name to a MSC Connection and use it. In case there
are multiple connections we can now more easily identify them.
This is only used for the NAT right now, the BSC could start to
name the various MSC connections too.
Currently the 'mgcp' command fails in the 'config-nat' node, because
it get confused with 'mgcp-through-msc-ipa' which is executed
instead because of the prefix based command selection. Thus the
latter command is renamed by this patch to avoid the common prefix.
The workaround in the test suite is removed.
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).
ournode_exit() duplicates most of bsc_vty_go_parent(). This patch
fixes the inconsistencies of both functions within
bsc_vty_go_parent() and replaces the implementation of
ournode_exit() by a call to it. This makes 'exit' behave exactly
like ^D in all openbsc nodes.
ournode_end() has been changed to walk through the intermediate
nodes until one of the top nodes is reached. This allows for
cleanups to be done on the way.
Note that in config mode if the tree is searched along the nodes
toward the config node and a command is not found this way, a
rollback is done by just replacing the vty's node and index member
variable by the saved old values which might break the whole thing, when
there has been a free() on the way.
These tests check for the availability of 'exit' and 'end' in each
configuration node and for the node specific commands to traverse
the tree.
In addition, using these commands from within inner contexts is
checked. This will detect problems, when an outer command word is
a prefix of an inner command, like with 'mgcp' and
'mgcp-through-msc-ipa'.
Several assertions are disabled due to inconsistencies and missing
commands (see above).
