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

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.

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.

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.

DISTCHECK_CONFIGURE_FLAGS="--enable-smpp" make distcheck

The jenkins runs make distcheck in the default configuration and
not with the nat enabled.
DISTCHECK_CONFIGURE_FLAGS="--enable-nat" make distcheck

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.

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.

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).
|
|
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).

There was no command to reset a bsc-welcome-text string, so it has
been added.

Send an USSD message on each MS connection if the connection to

This command returns the current state of the connection to the USSD

* The post-routing is applied after the first re-writing. To do this
the new number is copied back into the called data structure.
* Add a testcase that goes from 0172 to 0049 and then back to 0049
using the post rule with a table lookup.
|

The test cases did not free some of the resources it allocated.
Improve the situation a bit. There is still data allocated that
is not freed at exit.

* Increase the rewritten rule to five digits (this is the easiest
for the unit test). This will add another 40kb to the runtime size.
* Create a unit test that tests adding and removing the prefix rules.
* Use the regexp match to replace from one package
|
|
* It is a trie. The max depth of the trie is the length of the
longest prefix. The lookup is O(lookuped_prefix), but as the prefix
length is limited, the lookup time is constant.
* Each node can hold the entire prefix, has place for the rewrite
rule with up to three digits.
* A trie with 20k entries will take about 3MB ram.
* Filling the trie 100 times takes ~800ms on my i7 laptop
* 10.000.000 lookups take 315ms.. (for the same prefix).
* 93/99 lines are tested, 6/6 functions are tested, 49 of 54 branches
are tested. Only memory allocation failures are not covered
* A late addition is to handle the '+' sign and to increase the number
of chars in the rewrite prefix. The timing/line coverage has not
been updated after this change.

The test is just testing the invocation but does not verify that

Disable the periodic LU using "no periodic location update" VTY
command. In that case set the expire_lu to 0 which will then be
translated to a NULL in the database layer. This leads to a bit of
copy and paste in the db_sync_subscriber method but I don't see
how we could easily use 'datetime(%i, 'unixepoch')' and 'NULL'
at the same time.
Change the query to find expired queries to check for NOT NULL
and the time being in the past. This means if there are still
old subscribers in the database they might not be expired. One
would need to execute a query like "UPATE Subscriber SET expire_lu
= 0 WHERE expire_lu is null". The same applies when disabling the
periodic LU. One would need to update the database by hand.
Manual tests executed/passed:
1.) periodic LU enabled:
* use gst LUTest.st to do a LU
* UPDATE Subscriber SET expire_lu=datetime('now');
* observe the subscriber being expired (it was)
2.) periodic LU disabled:
* use gst LUTest.st to do a LU
* verify that the expire_lu is NULL in the database

We were expiring subscribers during active calls. This is because
the T3212 is stopped under certain conditions but we didn't stop
that timer at all.
Remember if T3212 timer was stopped due something done by NITB and
update the expiration time at the end of the radio connection, as
the phone should restart it when returning to MM Idle.
It is a bit difficult to decide when we should set the flag. E.g.
in a CM Service Request we don't know if we accept the service and
during a LU we already send MM messages before we accept or reject
the subscriber.
The easiest is to set the flag when receiving a paging response
on known subscribers and at the end of the authentication process.
Do not expire a subscriber that has an active connection that is
marked with the flag, e.g. we would still expire a subscriber that
is being paged.
Manual tests executed/passed:
* gst LUTest.st verified that a expiration date was set
* gst SMSTest.st (doing another LU but forcing a timeout on the
SMS sending). Verified that the expire_lu was updated.

Make sure to not ever have issues with this code again, move the
utility code to a new file and create a basic testcase. The method
currently has 100% line and branch coverage. My initial patched
missed the smpp_utils.c file and I re-did the copying (and verifying
the branch coverage)

The name sccp_connection is used in the osmo-sccp code, sccp_connections
was used in the NAT for tracking a sccp_connection. Rename it so it is
obvious that the struct belongs to the nat.

Prepend the international number with a '+' and then do the normal
re-writing on it. There are a couple of ways to handle this:
\+([0-9]), \+[0-9][0-9]([0-9]), \+49([0-9])
Add a test case for the international re-write based on an already
internationalized number.

We want to send a TRAP with the MGCP statistics from the NAT and
the connected BSC. The BSC endpoint can be either released because
of a DLCX from the MGCP CallAgent or the SCCP Connection release on
the A-link.
This is why we need to queue the statistics when the deleting the
endpoint on the BSC. The processing is continued once the response
arrives. This code assumes that the response of the DLCX will be sent
by the remote side. The current amount of outstanding responses can be
seen on the VTY. This assumption is based on the fact that the BSC has
already responded to the CRCX and maybe to the MDCX.
The MGCP RFC is bended to prefix the transaction identifier with "nat-"
to easily detect the response and hand it to the handler. This will
then parse the response and generate the TRAP. The current version is
v1. We assume that the transaction space is big enough and we will
not re-assign the transaction identifier too early.

Instead of handling MGCP through the UDP socket, read and write messages
through the ipa connection to the MSC.

Linking started to fail for me due the symbol coming from the
