|
* controlif: declare controlif_setup() in control_cmd.hHarald Welte2014-08-211-0/+3
| | | | | this avoids us to copy+paste external declarations over all 'main' files.
* libctrl: Add ctrl_cmd_cpy() to copy a commandDaniel Willmann2014-08-211-0/+1
|
* libctrl: Add macros to help define commandsDaniel Willmann2014-08-211-0/+69
|
* Add libctrl, an SNMP-like control interfaceDaniel Willmann2014-08-211-0/+81
| | | | | | In contrast to the VTY interface the control interface is meant to be used by programs. This patch adds basic support, no commands are defined.
* libosmogb: move files to proper location and fix buildHarald Welte2012-06-178-635/+0
|
* libgb: separate header files related to spec and implementationHarald Welte2012-06-176-219/+238
| | | | | | like in libosmogsm, we separate between header files that are just reflecting information in the respective specs, and header files that related to our specific implementation.
* libgb: make sure all BSSGP functions have bssgp_ prefixHarald Welte2012-06-171-7/+7
| | | | | We change the minority of functions employing the gprs_bssgp_ prefix to match with the majority without gprs_ in front.
* libgb/gprs: don't use log_info from libcommon anymoreHarald Welte2012-06-171-0/+3
|
* libgb: prefix all NS related functions with gprs_Harald Welte2012-06-171-9/+10
|
* libgb: don't call directly into GMM / LLC layerHarald Welte2012-06-171-0/+37
| | | | | | 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()"
* libgb: remove dependency of BSSGP to include sgsn/gmm internal structsHarald Welte2012-06-171-2/+15
|
* libgb: Remove dependency to openbsc/debug.hHarald Welte2012-06-163-0/+7
|
* libgb: Use library SS_L_NS instead lf local SS_NSHarald Welte2012-06-161-1/+13
| | | | | which removes some further dependencies of libgb to openbsc internal code and data.
* libgb: move GPRS specific msgb CB definitions to separate headerHarald Welte2012-06-164-1/+33
|
* split libgb into a separate library for outside useHarald Welte2012-06-164-0/+5
| | | | | This also removes the dependency to osmo_sock() inside libcommon and replaces it with osmo_sock_* from libosmocore
* misc: Deal with smatch warnings about the bitfieldsHolger Hans Peter Freyther2012-03-021-1/+1
| | | | Use unsigned ints for the bitfield.
* BSSGP: Add functions required for true BSS-side BSSGP implementationHarald Welte2011-11-251-1/+15
| | | | | | | | | The BSS-side of BSSGP requires quite a number of additional functions for sending unidirectional messages that a SGSN never sends. This is a first step into completing the BSSGP implementation and making it ready to be used from osmo-bts and other BTS-side GPRS implementations.
* BSSGP: add more doxygen commentsHarald Welte2011-11-251-25/+29

* src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso2011-03-232-5/+5
| | | | | | | | | | | 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>
* GPRS: Increase the NS msg size to 2048Holger Hans Peter Freyther2010-06-141-1/+1
| | | | | | | According to the GPRS NS spec the maximum framesize is 1600 octets for FrameRelay, it can be bigger if configured to be so. Make it 2048 octets to have some space available...
* [GPRS] BSSGP/SGSN: Implement Gb-Interface PagingHarald Welte2010-06-101-0/+27
| | | | | | | | | | | | | | | | We now have a function that generates BSSGP PS and CS paging request. It is called from the libgtp code when we receive a GTP packet from the GGSN for a MM context that is in SUSPEND state. We then issue a PS paging request to the Cell with the BVCI where the last RA update was being performed. TODO: We still don't enqueue the GTP packet (and transmit it on paging complete), and we don't rate-limit the paging requests, i.e. every GTP packet will trigger another paging request. We probably also need some kind of logic that marks the phone as UNREGISTERED if it doesn't respond to paging requests for some time.
* [GPRS] Include IMSI and DRX params in BSSGP DL-UDHarald Welte2010-05-311-1/+2
| | | | | | | | | When we send a downlink unit-data request via BSSGP, there is a lot of information that needs to be copied from the mm context, such as the IMSI, DRX parametes, MS radio access parameters, ... This is a quite strange layering violation, since we now need to pass a pointer to the MM ctx from GMM through LLC into BSSGP :(
* gprs_ns_frgre.h: Create the header and include itHolger Hans Peter Freyther2010-05-231-0/+6
|
* gprs: Fix warnings on funny casts for the return statementHolger Hans Peter Freyther2010-05-231-1/+1
| | | | | | | | Change gprs_nsvc_reset to return void instead of a int as the gb_proxy.c currently ignores the reutnr value anyway. Change the caller inside gprs_ns to return the newly allocated nsvc instead of the return of gprs_nsvc_reset.
* [GPRS] NS: Make sure we allocate NS packet with headroom for FR/GREHarald Welte2010-05-191-1/+5
|
* [GPRS] NS: VTY: Move all local ip/port bind values into 'ns' nodeHarald Welte2010-05-191-2/+6
| | | | | This removes the requirement for gb_proxy and sgsn to have duplicate vty parsing code
* [GPRS] Add Frame Relay in GRE encapsulation for NSHarald Welte2010-05-191-17/+22
|
* [GPRS] BSSGP: Use correct values for SIGNALLING and PTM BVCIHarald Welte2010-05-181-0/+4
|
* [GPRS] SGSN: Activate BSSGP VTY functionsHarald Welte2010-05-181-0/+3
|
* [GPRS] BSSGP: expose more internal structures / APIHarald Welte2010-05-171-0/+29
|
* [GPRS] NS: Always start NS-ALIVE procedure after RESETHarald Welte2010-05-151-0/+1
| | | | | | | | | So far, we only started the ALIVE procedure on RESET-ACK if the remote end was the SGSN. This resulted in the BSS->Proxy connections only being tested for alive-status from the BSS side, but not from our side. Also: export nsvc_by_nsvci() function as a public API function.
* [GPRS] gb_proxy: Initiate RESET procedure on persistent NS-VC at startupHarald Welte2010-05-141-0/+3
| | | | | | Some BSS that connect to the proxy do not continue to perform the RESET procedure after a timeout. In order to resurrect them, we simply start a RESET procedure.
* [GPRS] BSSGP: add function declarationHarald Welte2010-05-131-1/+6
|
* [GPRS] NS: Fix segfault when receiving message from unknown NS-VCHarald Welte2010-05-131-0/+3
| | | | | | | | | | | | In the previous code we used a static fake_nsvc structure in case we needed to send a message to an unknown NSVC for which we don't have a real 'struct nsvc'. However, since we now have a rate_ctr_group hanging off the nsvc, the fake structure didn't have that. So now we keep a nsi->unknown_nsvc around to be used whenever we need a nsvc but don't have a real one. The gprs_ns_vty.c code explicitly does not list that NSVC in 'show ns'
* [GPRS] NS: Start to use rate_ctr_group code from libosmocoreHarald Welte2010-05-131-0/+6
| | | | | | | | | Every NS-VC now has a set of counters for incoming and outgoing number of packets and bytes. We also split the VTY part of the gprs_ns.c implementation into gprs_ns_vty.c to make sure the protocol can actually be used without the VTY code being present.
* NS: Make all timers configurable from VTYHarald Welte2010-05-121-1/+21
|
* NS: Add support for persistent NS-VC configurationHarald Welte2010-05-121-1/+6
| | | | | | | | | With persistent NS-VC configuration (configured through VTY), we can respond properly to BSS with a somewhat strange NS implementation Such as the BSplus. It enables us to respond with a proper NS-RESET (including NSVCI/NSEI) when receiving a NS-ALIVE or other PDU for a BLOCKED/DEAD NS-VC after our end of the connection is rebooted.
* [gprs] gb_proxy: Send proper BSSGP STATUS msg in error caseHarald Welte2010-05-111-0/+12
| | | | | | | | | | | In order to reuse the existing bssgp_tx_* functions without pulling in the dependencies of gprs_bssgp.c, we have to move those functions to gprs_bssgp_util.c Furthermore, we can remove gbprox_nsi and replace it with bssgp_nsi, and we can do proper processing of BVC-RESET messages coming from the SGSN on the signalling BVC. In that case we need to send RESET messages to all the BSS.
* [gprs] NS: Add signals in the event of BLOCK/UNBLOCK/RESETHarald Welte2010-05-111-0/+3
| | | | | | The signals will be sent upon reception of NS-BLOCK/UNBLOCK/RESET PDUs We also export functions to generate/send BLOCK/UNBLOCK and RESET.
* [gprs] NS: improved timer handling for RESETHarald Welte2010-05-041-2/+2
