2016-05-20Use proper measurement for handoverMax1-5/+12
Previously *FULL measurements were always used for handover decisions. Those are incorrect in case of DTX - check if it was enabled and use *SUB instead. Note: *SUB values have higher variance so there might be more "bad" values compared to *FULL although real quality remains the same.

2016-05-15db.c: implemented incremental migrationVadim Yanitskiy1-18/+35
In the past, normal migration was possible only if the actual schema version differed from the version used in DB by 1. For example, if DB uses an old version 3 and you need to use it with the code written for version 5, the check_db_revision() will convert it to 4 and DB will still use incompatible schema version during Osmo-NITB running time. After next run it will be converted to version 5. This patch replaces a set of 'else-if' checks by a 'switch' without 'break' statements between 'case' labels (waterfall). It makes you able to migrate from current version to the latest despite any difference between them.

2016-05-05Add human-readable name of SGSN_AUTH_AUTHENTICATEHarald Welte1-0/+1
In commit 4adb136da63a1d3ed523ad85e12fd99fc62f5701 we introduced a new authentication state SGSN_AUTH_AUTHENTICATE, but we didn't add that to auth_state_names[] resulting in log messages printing it abut 'unknown 0x1' rather than something more useful.
2016-05-05sgsn/GSUP: Support MAP-style nested LU/ISDHarald Welte1-0/+22
The existing GSUP code expected the subscriber data to be piggy-backed onto the location update response, rather than a separate (and nested) insert subscriber data request/response phase. With this patch we should now support both the nested as well as the piggy-backed version.
2016-04-29osmo_oap_decode(): Use common argument orderingHarald Welte2-3/+3
In general, if a function generates output data like a msgb (or in this case filling an osmo_oap_message structure), the output argument precedes the source. This is what we use all over libosmo*, and it is modelled after memcpy(), where dst is the first argument, before src. Let's align osmo_oap_decode(). Intestingly, osmo_oap_encode was already correct, so the encode/decode functions used different conventions before.

2016-04-29rename gprs_shift_*() to osmo_shift_*()Harald Welte4-47/+86
This rename is the first step of moving the associated functions into libosmocore. Also, rename gprs_match_* to osmo_match_shift_* to indicate that it is not just matching the TLV, but also shifting the data portion.
2016-04-29Rename gprs_gsup_* to osmo_gsup_*Harald Welte3-108/+108
This is a preparation to move the related code to libosmocore, whilst at the same time generalizing it from GPRS Subscriber Update Protocol to the Osmocom Generic Subscriber Update Protoco.

This requres the corresponding commit in libosmocore.
2016-04-29Start to use struct osmo_auth_vector from gsm_auth_tupleHarald Welte8-61/+61
Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway. If a usre of the code needs key_seq, they need to manage it themselves.
2016-04-29Disconnect calls with incompatible channel types / modesMax1-1/+45
In case both TCH/H and TCH/F or different codecs are configured and internal MNCC handler is used we might end up in a situation where call legs with incompatible channel types or codecs would be connected resulting in a broken audio.

Introduce new configuration option bscs-config-file which includes BSC configuration from the given file. Both absolute and relative (to the main config file) paths are supported. Add 'show bscs-config' command to display current BSC configuration. Note: it is still possible to have BSC configuration in the main file (provided proper index number is used) and in runtime but BSC configuration is no longer saved automatically.

2016-04-07ctrl: Extend ctrl command to optionally handle alg+kiHolger Hans Peter Freyther1-2/+58
Extend the existing ctrl command to be able to specify the algorithm and Ki. In contrast to the VTY no size check is done. Together with the VTY this code only supports a small part of what is supported by libosmocore. The algorithm and ki are considered optional but if a valid algorithm other than "none" is passed, a KI must be passed as well. Extend the test coverage by passing the potential values. It is not verified that the KI/algorithm is stored.
2016-04-06db: If creating a subscriber in the db fails, return NULLHolger Hans Peter Freyther1-1/+4
We should not return a subscriber in case it was not written to the database. Instead free the memory allocated and return NULL. Callers in gsm_04_08.c are prepared to have the creation fail. Related: OS Issue #1657
2016-04-06subscr: Make db_create_subscriber fail on duplicatesHolger Hans Peter Freyther2-13/+13
The issue of db_create_subscriber updating an already existing subscr is that the same subscriber will then have two entries in the active subscribers list. In general this will break assumptions that a subscr can be compared by comparing the pointer. In the case of the VTY this was not an issue as the created subscr was immediately destroyed again but it is better to avoid this problem. Change the VTY command to find the subscriber and then call sync to have the updated time set. The side-effect is we will now have two queries for the subscriber. Once through subscr_get_by_imsi and once through db_create_subscriber. Change the db_create_subscriber to fail if a subscriber already exists, and add a testcase for this behavior and do not updated the 'updated' timestamp of an already existing subscriber. Add a testcase for this behavior. Related: OS Issue #1657
2016-04-01bsc: Add parameter to restart a btsHolger Hans Peter Freyther1-1/+11
The ip.access nanoBTS seems to have severe issues with BSSGP when changing the country code and/or network code. It is unlikely that the proprietary code is getting fixed so we extend the parameter for the apply-configuration command to carry the 'restart' param.
2016-04-01bsc: Add code to send ip.access reboot command to nanoBTSHolger Hans Peter Freyther1-0/+39
The nanoBTS continues to be buggy and seems to have broken BSSGP when changing SIs across new OML connections. Add an easy command to force the reboot of the system through OML.
2016-04-01abis: Send the message without enforcing to wait for a responseHolger Hans Peter Freyther1-1/+1
The user might issue restarts while no BTS is connected and we should not block the abis queue because of these messages.
