In gsm04_08_clear_request(), in_release == 1 anyway and
msc_release_connection() would exit immediately without any effect. Don't
confuse the reader by passing release=1 arg.

subscr_name() was called from several places:
* either without a check for subscr being NULL, which for example
was causing a segfault if we hand-over a channel before identifying the
subscriber
* or with an explicit NULL check and the ternary operator (?).
We now simplify the code by checking for the NULL Subscriber in subscr_name()
itself.

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.

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.

We recently implementd InsertSubscriberData in the SGSN, adapt the test
to reflect that.
|
|
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.
|
|
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.
|
|
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.
|
|
* we always declare stack variables at the top of the function / block
* 'switch' is not a function, so there's space ahead of the opening (
|
|
this is in preparation of moving related code to libosmocore.

This is a first step to moving oap_messages.h to libosmocore

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.
|
|
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.

... rather than our private definitions everwhere. As an added benefit,
gprs_gsup_messages.h is now free of any header dependencies within
openbsc.
|
|
This requres the corresponding commit in libosmocore.
|
|
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.

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. Disconnect such calls with appropriate
error message.

This adds a very basic, use once example in python on how to connect

complete as the invokeId should be patched according to the initial
invoke. This excercise is left to future readers of that code.

On start this would print one line per BSC and this doesn't add
