2015-06-15bsc: Attempt to fix crash when sending a SCCP CREF messageHolger Hans Peter Freyther1-1/+1
There was no context for the SCCP CREF message and this means that the msc_con was a plain NULL pointer that was dereferenced and the application would crash. Use the new API to pass the incoming MSC Connection which sould be used for the SCCP CREF message as context. The code has not been fed with an actual SCCP CR message.
2015-04-01bsc: Allow to use different LAC/CI for the core-networkHolger Hans Peter Freyther1-2/+4
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. Related: SYS#1398
2014-10-29bsc: Allow to disable sending ping/pong to the MSCHolger Hans Peter Freyther1-1/+1
Some switches do not like to receive the IPA PING/PONG messages. Allow to disable the handling with "no timeout-ping" and create test cases that verify the switching between the modes. Change the code to trat <= 0 as an invalid timeout. Fixes: SYS#713
2014-09-05bsc: Add a "IPA PING" to the SCCP CR messagesHolger Hans Peter Freyther1-8/+36
We want to reduce the background traffic and might set the ping interval to be in the range of minutes. But this means that if the TCP connection is frozen several "SCCP CR CM Service Requests" will be stuck in the send queue without ever being answered. I could have used the logic of not receiving the "SCCP CC" to close the connection but instead I am introducing an overload to schedule the ping as part of the normal SCCP connection establishment. The VTY write case has been manually verified, I have also looked at a single trace to see that the SCCP CR and the IPA PING is transfered in the same ethernet frame.
2014-08-21libctrl: Move bulk of node lookup code into libosmocoreHarald Welte1-1/+1
Now that the bulk of the control interface node lookup has no reference to the BSC specific data structures, we are moving it into libosmocore. A control interface user now only registers an optional small node lookup function like bsc_ctrl_node_lookup()
2014-08-21move libctrl from openbsc to libosmoctrl (libosmocore.git)Harald Welte1-2/+2
2014-08-20adopt recent IPA related symbol renameHarald Welte1-3/+3
... which happened during recent migration of IPA functionality from libosmo-abis into libosmocore.
2014-05-06nat/bsc: Check proto before calling ipaccess_rcvmsg_baseHolger Hans Peter Freyther1-1/+1
The code in the BSC/NAT called ipaccess_rcvmsg_base without checking if the protocol is IPA. This lead the BSC to respond to SCCP messages with an "ID ACK". From a quick look neither the code of ipaccess_rcvmsg_base in OpenBSC nor the copy of libosmo-abis ever checked the protocol header. So this code has been wrong since initially being created in 2010.
2014-04-01ipa: Use enhanced ipa_msg_recv_buffered() to cope with partioned IPA messagesJacob Erlbeck1-2/+4
The old ipa_msg_recv() implementation didn't support partial receive, so IPA connections got disconnected when this happened. This patch adds the handling of the temporary message buffers and uses ipa_msg_recv_buffered(). It has been successfully tested by jerlbeck with osmo-nitb and osmo-bsc.

2014-03-23ctrl: Move the lookup into a separate file in preparation for GPRSHolger Hans Peter Freyther1-1/+2
For GPRS the look-up via bts/trx does not make any sense and would introduce bad depdencies for the SGSN. Move the look-up code to a new file and introduce new setup methods.
2013-01-15bsc: Introduce an authenticated signal for the MSC connectionHolger Hans Peter Freyther1-0/+4
Send the signal whenever a MSC appears to be authenticated.
2013-01-07audio: Make the BSC handle the new mr_config request of the BSC APIHolger Hans Peter Freyther1-0/+3
Handle the mr_config request and set the AMR multirate config for the given MSC. Initialize the mr_config with the AMR5.9 default we have been using until now.
2012-09-11bsc: Look for CM Service Requests with emergency causeHolger Hans Peter Freyther1-0/+1
Look for emergency calls and send them to a MSC that can handle them properly.
2012-03-16bsc: Prepare to have multiple MSC connectionsHolger Hans Peter Freyther1-0/+40
We now have a list of MSCs but in the code we will try to access the MSC with the nr 0.
2012-03-16bsc: Use the right connection for outgoing packetsHolger Hans Peter Freyther1-1/+1
This is needed for simple UDT messages where we do not have a SCCP connection.
2012-03-16bsc: Move more things to use osmo_msc_data* directlyHolger Hans Peter Freyther1-3/+1
2012-03-16bsc: Stop using net->bsc->msc and get the right msc from somewhere elseHolger Hans Peter Freyther1-0/+1
2012-03-16bsc: Create a osmo_bsc_data and embed osmo_msc_dataHolger Hans Peter Freyther1-1/+1
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.
2011-08-19src: port openBSC over libosmo-abis0.9.15Pablo Neira Ayuso1-7/+10
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.
2011-07-13osmo_bsc: Use libctrl, handle ctrl cmds on port 4249 or from the natDaniel Willmann1-0/+34
This patch initializes libctrl to listen for connections on port 4249. Additionally, control messages arriving from the nat will also be processed.

2011-04-26bsc: Allow to have a list of MSCs/MUXs to connect toHolger Hans Peter Freyther1-3/+1
Be able to configure a list of destinations (duplicates allowed) that will be tried in a round robin fashion. The change is in the bsc_msc_connection to operate on a list. We achieve the round robin nature with the same trick used in the paging code to delete and append the current entry. The nat code was updated to compile but one can only configure one destination.
2011-04-26bsc: Allow the NAT to query the list of LACsHolger Hans Peter Freyther1-3/+38
Right now the code assumes that any request coming from the NAT is a query and the code responds to with a list of configured LACs.
2011-04-26bsc: Handle MGCP coming from Osmo Extensions headerHolger Hans Peter Freyther1-0/+20
Start using the new Osmo Extension header and forward MGCP to the MGCP GW.
2011-03-23Fix build of bsc-nat and GPRS code after include path changeHarald Welte1-1/+1
The last patch changed the osmocore include paths, this fixes some build problems caused by it
2011-03-23src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso1-1/+1
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] Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-03re-structure the OpenBSC directory layoutHarald Welte1-0/+368
The new structure divides the code into a number of libraries for the BSC core functionality, MSC core functionality, Abis transport, TRAU and other bits. This doesn't introduce any functional code change but simply moves around files and alters Makefile.am accordingly. Next step would be to disentangle a lot of the inter-library dependencies and make the individual bits of code more independent.
