* GPRS: Fix compiler warning that will also lead to a crash at runtime.Holger Hans Peter Freyther2010-06-091-1/+1

* [GPRS] BSSGP: Fix formatting of BSSGP TX STATUSHarald Welte2010-06-031-1/+2

* [GPRS] Major LLC / TLLI handling fixesHarald Welte2010-06-011-1/+1
| | | | | | | | | | | | | * separate the LLME and LLE state in the LLC layer * introduce gprs_llgmm_assign() function for LLGMM-ASSIGN.req primitive * change QoS profile to match 'real' SGSN * Update the new TLLI when assigning a P-TMSI The result now is that the LLC layer is notified of TLLI changes, which in turn means it doesn't allocate a new LLE structure every TLLI change, which again in turn means that the UI frame sequence number does not reset to zero. As a result, MS should no longer ignore frames based on wrong UI sequence number.
* [GPRS] Include IMSI and DRX params in BSSGP DL-UDHarald Welte2010-05-311-2/+34
| | | | | | | | | 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] BSSGP: Fix way too long TLLI debug lineHarald Welte2010-05-311-1/+1
|
* [GPRS] BSSGP: More verbose debug log / error reportingHarald Welte2010-05-311-34/+86
|
* [GPRS] BSSGP: When we receive a BLOCK, we should not respond with UNBLOCK-ACKHarald Welte2010-05-311-2/+1
|
* [GPRS] NS: Fix GRE keepalive response in FR-GRE encapsulationHarald Welte2010-05-311-2/+2
|
* [GPRS] BSSGP: Acknowledge all SUSPEND and RESUME requestsHarald Welte2010-05-301-0/+103
| | | | | | This is of course not the correct way of dealing with it, but for now it should make the Ericsson Mobile Plafrom based phones happy (they insist to do a suspend/resume cycle before pdp ctx act)
* [GPRS] NS: correctly pass the NS payload length to the TLV parserHarald Welte2010-05-301-7/+9
|
* [GPRS] NS: Don't hand Frame Relay LMI packets into the NS codeHarald Welte2010-05-281-5/+15
|
* [GPRS] NS: Respond to GRE keepalive messagesHarald Welte2010-05-281-1/+67
| | | | | | | GRE has the strange notion of keepalive messages being encapsulated IPv4 packets adressed back to the sender. Since we actually really only care about frame relay, this is a bit strange. However, we'll do some sanity checks and send it back through our GRE socket...
* [GPRS] NS: Frame Relay DLCI for PVC from 16-1007Harald Welte2010-05-281-1/+1
| | | | | | | | | 0 Reserved for ANSI Annex D and CCITT Annex A link management 1 - 15 Reserved 16 - 1007 Any PVC 1008 - 1018 Reserved 1019 - 1022 Reserved for LMI multicast 1023 Reserved for LMI link management
* [GPRS] NS: Print error message if TLV parser fails for some reasonHarald Welte2010-05-281-0/+22
|
* [GPRS] NS: Start TEST procedure, not ALIVE procedure, on RESET/RESET_ACKHarald Welte2010-05-281-2/+3
| | | | | | | | | | | | According to the spec, after an incoming RESET or RESET_ACK, we shall start the TEST procedure, not the ALIVE procedure. Also, when we start the TEST procedure, we have to always send a NS_ALIVE packet at the same time (we didn't in the case of incoming RESET). Furthermore, we now only start TIMER_TNS_ALIVE from within the TIMER_TNS_RESET callback code, where we also make sure that the alive_retries counter is reset to zero.
* gprs: Subtract the headroom for what we can receiveHolger Hans Peter Freyther2010-05-281-1/+1
| | | | | The buffer got allocated with headroom and we need to subtract that from the size of the buffer.
* Migrate VTY code to libosmovtyHarald Welte2010-05-252-6/+8
|
* [GPRS] NS: Always generate LOG_INFO message when we block NS-VCHarald Welte2010-05-251-0/+5
|
* gprs_ns_frgre.h: Create the header and include itHolger Hans Peter Freyther2010-05-231-0/+1
|
* gprs_ns.c: Make make_socket known to the compilerHolger Hans Peter Freyther2010-05-231-0/+1
|
* gprs: Fix warnings on funny casts for the return statementHolger Hans Peter Freyther2010-05-231-4/+3
| | | | | | | | 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_bssgp.c: Return something from non void methods.Holger Hans Peter Freyther2010-05-231-1/+3
| | | | | In one use the rc variable we are assigning to, in the others return 0 even if we have a FIXME there.
* gprs_bssgp.c: Cast const of TLVP_VAL away.Holger Hans Peter Freyther2010-05-231-2/+2
| | | | | | Fix a compiler warning, we cast the const away at various other parts in the code as well. We should consider removing the const from the TLV struct..
* [GPRS] NS: Better formatting of VTY outputHarald Welte2010-05-191-6/+8
|
* [GPRS] NS: properly parse FR DLCI on RxHarald Welte2010-05-191-10/+4
|
* [GPRS] NS: Never respond to STATUS with STATUS to prevent loops!Harald Welte2010-05-191-0/+6
|
* [GPRS] NS: SOCK_RAW sockets always provide the full IPv4 header on receiveHarald Welte2010-05-191-5/+14
|
* [GPRS] NS/FR/GRE rcvmsg case: msgb_free() in error caseHarald Welte2010-05-191-3/+2
|
* [GPRS] NS: Make sure we allocate NS packet with headroom for FR/GREHarald Welte2010-05-191-6/+6
|
* [GPRS] NS: FR/GRE: Use AF_INET, correctly encode FR DLCI and GRE payload typeHarald Welte2010-05-191-3/+4
|
* [GPRS] NS: VTY: Move all local ip/port bind values into 'ns' nodeHarald Welte2010-05-193-4/+98
| | | | | This removes the requirement for gb_proxy and sgsn to have duplicate vty parsing code
* [GPRS] Add Frame Relay in GRE encapsulation for NSHarald Welte2010-05-193-16/+314
|
* [GPRS] SGSN: properly delete a PDP context after receiving PDP CTX DEACT REQHarald Welte2010-05-181-0/+4
|
* [GPRS] BSSG: Fix Vty printing of BVCHarald Welte2010-05-181-1/+1
|
* [GPRS] BSSGP: Use correct values for SIGNALLING and PTM BVCIHarald Welte2010-05-181-5/+5
|
* [GPRS] BSSGP: Add VTY for configuration and inpectionHarald Welte2010-05-172-0/+181
| | | | This also includes log filtering based on NSEI/BVCI tuple
* [GPRS] BSSGP: Introduce packet/byte countersHarald Welte2010-05-171-0/+17
|
* [GPRS] BSSGP: expose more internal structures / APIHarald Welte2010-05-171-27/+4
|
* [GPRS] BSSGP: Rename bssgp_bts_ctx to bssgp_bvc_ctxHarald Welte2010-05-171-19/+19
| | | | | | The Context really is about a BVC (BSSGP Virtual Connection). In the case we operate BSSGP on the SGSN side, this corresponds to a link to a BTS.
* [GPRS] NS: Receiving a STATUS message is a NOTICEable eventHarald Welte2010-05-161-2/+2
|
* VTY: Context-sensitive help for logging related commandsHarald Welte2010-05-161-1/+1
|
* [GPRS] NS: Allow filtering of log messages by NSVC / NSEIHarald Welte2010-05-152-1/+56
|
* [GPRS] NS: VTY: Don't nsvc_delete() on 'no nse...'Harald Welte2010-05-151-3/+9
| | | | | | | Rather than deleting the NSE from memory, we simply mark it as non-persistent. This makes sure that there are no invalid references (e.g. from gbprox_peer) to the gprs_nsvc structure, but at the same time ensures it will no longer be stored as part of writing the config file.
* [GPRS] NS: Introduce command to display a single NSEHarald Welte2010-05-151-12/+47
|
* [GPRS] NS: Always start NS-ALIVE procedure after RESETHarald Welte2010-05-151-9/+6
| | | | | | | | | 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] NS: Add 'nsvc nsei ... (block|unblock|reset)' command to VTYHarald Welte2010-05-141-0/+33
|
* [VTY] Introduce "end" command that works from any level in configHarald Welte2010-05-141-0/+1
| | | | | | Using "end" you can always return to the "enable" level, and from there the "show" commands are available. So no more need for exit/exit/exit/exit/disable.
* [VTY] Remove OpenBSC specific node-exit handling from src/vtyHarald Welte2010-05-141-0/+2
| | | | | The idea is to move the VTY code into libosmocore at some point, and for that we need to eliminate OpenBSC specifics from it
* [GPRS] gb_proxy: Initiate RESET procedure on persistent NS-VC at startupHarald Welte2010-05-141-15/+18
| | | | | | 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: Refuse blocking of signalling BVC; Ignore traffic on blocked BVCHarald Welte2010-05-131-0/+22
