Before sending mm info message to ms:
- try to find virtual network with the imsi prefix which matches subscriber's imsi
- if virtual network was found, use long and short network names of this virtual network for subscriber
- if virtual network was not found, use long and short network names of main network for subscriber

default-route would only be looked at after there has been
no subscriber in the local database. Depending on the setup
this is not what one wants. This has been discussed at the
OsmoDevCon and there have been hacks in some branches. Let's
introduce a VTY command to select if SMPP should be consulted
first and then fallback to the current behavior.

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".

We need to use different LAC/CI towards the core network.
It is a bit problematic as LAC/CI is a per BTS attribute
so this feature only works if a BSC manages everything in
the same LAC.

For most configurations we don't address multiple GGSNs but
only want to enforce a list of APNs. In the future we might
add a special global GGSN context but not right now.
Fixes: SYS#593
|
|
This commit adds the exported functions apn_ctx_find_alloc,
apn_ctx_free, apn_ctx_by_name, and apn_ctx_match to manage and
retrieve APN to GGSN mappings.
The following VTY commands are added to 'config-sgsn':
- apn APN ggsn <0-255>
- apn APN imsi-prefix PREFIX ggsn <0-255>
which maps an APN gateway string to an SGSN id. The SGSN must be
configured in advance. When matching an APN string, entries with a
leading '*' are used for suffix matching, otherwise an exact match is
done. When a prefix is given, it is matched against the IMSI. If
several entries match, a longer matching IMSI prefix has precedence.
If there are several matching entries with the same PREFIX, the entry
with longest matching APN is returned.

The cancellation type that is part of the UpdateCancellation message
is currently ignored.
This patch adds the missing glue between the existing GSUP and GMM
support. If the type is not present or has the value updateProcedure
the subcriber and MM context are siliently removed. Otherwise, a
message with cause 'implicitly detached' is sent to the MS. Since the
real cause is not known (the specification neither added a cause IE
nor defined a static cause value), the MS may get the real cause in
the following AttachRej.
Added VTY commands:
- update-subscriber imsi IMSI cancel update-procedure
- update-subscriber imsi IMSI cancel subscription-withdraw
the old form without the cause is no longer supported.

Currently the keep_in_ram flag is explicitely reset in
gprs_subscr_cleanup to cover the case, that the VTY 'create'
sub-command has been used to create the subscriber entry.
This commit completely removes keep_in_ram handling from
gprs_subscriber.c and adds a VTY 'destroy' sub-command to reset the
flag and remove the entry. So 'create' and 'destroy' can be used to
manager sticky entries that are kept even when a location
cancellation is done.
Added VTY command:
- update-subscriber imsi IMSI destroy

This patch drops the following commands:
- update-subscriber imsi IMSI insert authorized <0-1>
- update-subscriber imsi IMSI commit
since they are already covered by the 'update-location-result'
sub-command, except that this command doesn't create an new entry if
none is found with the given IMSI.
It adds the following command:
- update-subscriber imsi IMSI create
which can be used to create a new entry.

This adds the following commands to the ENABLE node:
- show subscriber cache
- update-subscriber imsi IMSI insert authorized (0|1)
- update-subscriber imsi IMSI cancel
- update-subscriber imsi IMSI commit
These commands are mainly testing tools and maintenance helpers. The
update commands work asynchronously and can be used to complete a
pending update request or to terminate an existing connection. The
'insert' command just update the subscriber records but does not
notify the GMM layer. Invoke the 'commit' command to continue with
pending procedures.
Note that the subscriber cache is not stored persistently and will
always be empty after an SGSN restart.

This commit adds a new authorization policy 'remote' and uses
the subscriber cache for authorization when this policy is being used.
Note that there is no remote backend implemented yet. After the
IMSI/IMEI have been acquired, a request would be sent to the remote
peer. The attach/auth-ciph procedure continues when authorization
info has been received from the peer. This means, that
gprs_subscr_update() must be called then to tell the GMM layer
that it can proceed. A later commit will add VTY commands to do this
manually.

Equipment like AudioCode appears to get upset when we use a
builtin type and then assign a name to it. Allow to completely
omit the name.

Currently the VTY 'auth-policy' command results in setting or clearing
the acl_enabled flag. This also enables the matching of the MCC/MNC
prefix of the IMSI.
This patch adds an additional policy 'acl-only' which disables the
MCC/MNC matching and relies on the ACL only.

When the command was added it was not verified that. Add a very

Make sure that bsc_gsmnet->bsc_data->rf_ctrl is initialized for

The iPhone5 (US) appears to have some issues with the SIs generated,
or the nanoBTS is not sending them correctly.
Add a configurable hack to put all bands into the SI2/SI5 message.
It is enabled by the bts VTY command 'force-combined-si'.
This is a quick change without much reflection and watching for side
effects. I have verfied that a network with ARFCN 134 and neighbors
ARFCN 130 and 512 do not get generate the SI2ter and announce everything
inside the SI2.
This patch is conceptually based on 'si: Add a hack to disable
SI2ter/SI2bis/SI5ter/SI5bis messages' (692daaf2d2).

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 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.

This prevents the application from crashing when there is a half

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).

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
