Since it is planned to use struct gsm_subscriber to manage subscriber
data in the SGSN, this file which contains the generic subscriber
related methods is moved to libcommon.

Currently libcommon depends on libbsc, because gsm_network_init
(libcommon/gsm_data.c) directly calls gsm_net_update_ctype
(libbsc/gsm_04_08_utils.c).
This patch moves gsm_network_init to a new file libbsc/net_init.c.

Remove ournode_exit_cmd, ournode_end_cmd, and bsc_install_default()
since this functionality is provided by the current libosmocore.
Replace calls to bsc_install_default() by call to
vty_install_default() with the following semantic patch:
@rule1@
expression N;
@@
- bsc_install_default(N);
+ vty_install_default(N);

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).
ournode_exit() duplicates most of bsc_vty_go_parent(). This patch
fixes the inconsistencies of both functions within
bsc_vty_go_parent() and replaces the implementation of
ournode_exit() by a call to it. This makes 'exit' behave exactly
like ^D in all openbsc nodes.
ournode_end() has been changed to walk through the intermediate
nodes until one of the top nodes is reached. This allows for
cleanups to be done on the way.
Note that in config mode if the tree is searched along the nodes
toward the config node and a command is not found this way, a
rollback is done by just replacing the vty's node and index member
variable by the saved old values which might break the whole thing, when
there has been a free() on the way.
It appears to me that for NM_OC_BS11 mo was either NULL or the
one mo value from NM_OC_BS11_RACK. The break inside the nested
switch case didn't break from the outer one.
Fixes Coverity: CID 1040728
The support has been implemented for an old model, we were told that
newer versions would be made incompatible with OpenBSC. Ther are
various warnings in the code and coverity has found some new ones.
Just remove the code as we don't know of anyone using this code.
The sysmobts is now having a SAPI queue with all pending SAPI operations
on the BTS. Add the llist_head to the lchan and make sure it is initialized
by the shared code.
The message was corrupt at several points. They are fixed now and
successfully tested.
A default T3122 timer value of 10 is defined by default now. If set to 0,
the reject message will not be sent. Note that when using existing configs
with T3122 value set to 0.
For short IP failures we want the RF to stay up and wait for
the re-connect but in case the A-link is gone too long it is
good to switch off the RF and wait for commands to enable it
again.
libcommon: Default to 30min location update period
libbsc: Limit VTY value for periodic update and disallow the value 0
According to GSM 04.08 Table 10.5.33 "The value 0 is used for infinite
timeout value i.e. periodic updating shall not be used within the cell."
This was the default value until now, but the code that deals with
expiring inactive subscribers in the next commit can't handle that case
so this remains a TODO for now.
If the CHAN ACTIV is NACKED we set the state backto NONE. This is
problematic as our channel allocator will allocate from the front
or from the back and if the channel is early in the list it might
cause permanent failures. Introduce a BROKEN state and use it when
the channel activation is failing for an unknown reason. Copy the
cause so it can be inspected later.
In order to keep mobile at PACCH as long as possible the timer T3192 is
set to 1500ms. This reduces the probablity of long lasting assignment
process on CCCH for subsequent downlink TBFs.
gcc does not really know the _NR_OF_ELEMENTS_IN_ENUM approach, add
the _NUM_GSM_BTS_TYPE to the handled cases.
gsm_data.c: In function ‘gsm_set_bts_type’:
gsm_data.c:349:2: warning: enumeration value ‘_NUM_GSM_BTS_TYPE’ not handled in switch [-Wswitch]
so far, osmo-bts/sysmobts used to be entered as "sysmobts" type in the
configuration file. However, there are some differences in the
protocol/behaviour and we should reflect that by a new BTS plugin (with
lots of code reuse from the nanobts driver).
We want to have multiple MSCs but we also have some data
that is only present on a per BSC basis. Right now the
MSC data is not allocated with talloc, so we have some
change in the talloc contexts.
Assume nothing special needs to be done for the Nokia
*site hardware.
GCC warning:

gsm_data_shared.h includes e1_input.h of libosmo-abis, add the
LIBOSMOABIS_CFLAGS to Makefile.am, remove AM_LDFLAGS at the same
time as we only build .a archives.
In order to have the MNCC application reliably decide on the codec type,
it needs to know if we are running on a TCH/F or TCH/H. Thus, we pass
lchan_mode as a new parameter to the 'struct gsm_mncc'
Move the regexp parsing code from the NAT to libcommon as it will
be used by the NAT and BSC code. This also adds the #include <regex.h>
include to gsm_data. This header should be split up.
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.
Reset the BTS MO State on BTS bootstrap. This way we will always
test the BTS disconnect/reconnect case of the BTS.
Do not reset the administrative state of objects. The BSC might
have set these and wants to maintain them across disconnect/
reconnect. Right now this is true for the TRX state.
