It mentioned AGPLv3+ and refers to the hyperlink of v3, but still
stated "Version 2 or later". That was a typo at the time.

clang complained that different enums are mixed with the
return type and we actually want this to be an int now.

For real networks we need to check if the requested APN string
is allowed and then resolve the GGSN address through DNS. There
are countries with two or three digit MNCs and one could either
try to keep a list of countries that have two/three digits or
just try both of them. I have opted for the later for the ease
of the implementation.
C-Ares doesn't allow to cancel a request so we will need to
have the MMCTX and the Lookup have different lifetimes. We simply
set ->mmctx to NULL in case the MMCTX dies more early.
The selected and verified apn_str will be copied into the out
parameter. In case no static APN/GGSN config is present and the
dynamic mode is enabled a request will be made.

This is consuming the new signals and allows to install several
different CDR/observing/event/audit modules in the future. For
getting the bytes in/out the code would have had to undo what the
rate counter is doing and at the same time adding a "total" to
the ratecounter didn't look like a good idea, the same went for
making it a plain counter.
Begin writing the values one by one and open/closing a new FILE
for every log messages. This is not efficient but easily deals
with external truncation/rotation of the file (no fstat for and
checking the links and size). As usual we will wait and see if
this is an issue.
Add some new members to our PDP context structure to see what it
is about.

Currently old LLMEs and MM contexts that haven't been explicitly
detached or cancelled are not removed until another request with the
same IMSI is made. These stale entries may accumulate over time and
severely compromise the operation of the SGSN.
This patch implements age based LLME expiry, when the maximum age has
been reached, the corresponding MM context is cancelled. If such an MM
context doesn't exist, the LLME is unassigned directly.
The implementation works as follows.
- llme->age_timestamp is reset on each received PTP LLC message
- sgsn_llme_check_cb is invoked periodically (each 30s)
- sgsn_llme_check_cb sets the age_timestamp to the current time if
it has been reset
- sgsn_llme_check_cb computes the age and expires the LLME if
it exceeds gprs_max_time_to_idle()

This commit adds GSUP client configuration (via VTY), connection set
up, and real message sending.
The following configuration commands are added:
- gsup remote-ip A.B.C.D set server IP address
- gsup remote-port PORT set server TCP port

This patch adds GPRS specific functions for gsm_subscriber objects
(allocation, retrieval, deletion) and subscriber data
requests/updates. The sgsn_update_subscriber_data callback is used to
notify the sgsn about updates and is extended by a parameter that
passes a reference to a gsm_subscriber.

Currently the function in sgsn_auth.c either have an sgsn_config or
an sgsn_instance parameter. Since then global sgsn variable is
already being used in that file and since other parts of the SGSN
related code also rely on a global sgsn singleton, these parameters
pretend to provide a flexibility that is not really supported.
Therefore this patch removes these parameters except for the ACL
related functions, which do not call code that uses the sgsn
variable.

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.

Currently the ACL code is located in sgsn_vty.c.
This commit moves this to a new file sgsn_auth.c as a first step to
make authorization more flexible in order to implement remote
acquisition on subsciber data.

Add the control interface with no hierachy right now and implement
the first command to list IMSI + Context Address of active sessions.
sgsn_cmd_handle could share more code with bsc variant.
Fixes: SYS#264, SYS#265

This adds a minimalistic ACL by which certain, individual roaming IMSIs
can be authorized to use the SGSN. So you can selectively bypass the
'MCC+MNC == first 5 digits of IMSI' checking for a couple of IMSIs

Require a 0.5.2+ libosmogb due the change of the suspend_ref type.

We change the minority of functions employing the gprs_bssgp_ prefix to
match with the majority without gprs_ in front.
|
|
|
|
Instead of direct function calls to individual functions, we now
generate primitives (osmo_prim) and send them to one
application-provided function "bssgp_prim_cb()"
|
|
|
|
Rather than using openbsc internal data/functions, we now use only
internal and libosmocore-provided ones.
|
|
which removes some further dependencies of libgb to openbsc internal
code and data.

This also removes the dependency to osmo_sock() inside libcommon and
replaces it with osmo_sock_* from libosmocore

This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.

Use the libosmocore code to ignore certain signals by
default (e.g. SIGHUP, SIGPIPE) and use the new code to
create a default stderr logging target and initialize
it properly.

These are not needed any more. We used them for u_int
types but we now use uint which comes from stdint.h

This was done with sed on the files.

libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.

We should use VTY_NEWLINE but our strings are static, always
use \r\n as unix terminals can handle that as well.
