2015-04-17sms: Add more logs for debugging sms delivery issuefairwaves/rhizomatica-masterIvan Kluchnikov1-0/+1
2014-05-06smpp: Force all SMSs to SMPPIvan Kluchnikov1-3/+3
2014-05-06sms_queue,smpp: Refactor MO SUBMIT code to make further changes easier.Alexander Chemeris1-26/+40
This is required to implement normal prefix/regexp routing in addition to the current "if unroutable" model.
2014-04-30sms: Kill the sms->sender and use addr/ton/npi throughout the codeHolger Hans Peter Freyther1-6/+3
This is an incompatible database schema change. Store the type of the address in the database for both the sender and the receiver. Currently it is possible to use SMPP to store a SMS and the NPI and TON will be lost on the delivery of the SMS. The schema is changed to make the delivery always use the right NPI/TON. This patch is not ready for the master branch as there is no upgrade path for the HLR yet.
2014-03-09sms: Rename gsm340_gen_tpdu() to gsm340_gen_sms_deliver_tpdu()Alexander Chemeris1-5/+5
Rename gsm340_gen_tpdu() to gsm340_gen_sms_deliver_tpdu() to show that it generates SMS-DELIVER TPDU and is not a generic function.
2014-03-09db,sms: Rename db_sms_mark_sent() to db_sms_mark_delivered()Alexander Chemeris1-1/+1
In MT-SMS the message is being delivered. Make the naming follow that. The schema still refers to "sent" while it should be "delivered" too.
2014-02-24sms: Do not interfere with the SMS queue from within gsm_04_11Holger Hans Peter Freyther1-11/+0
It was possible that two SMS would be delivered at the same time which violates GSM 04.11. We should solely rely on the sms queue to schedule more SMS to the subscriber.
2014-02-20sms: Increment the RP Message Reference for each transactionHolger Hans Peter Freyther1-2/+2
Each RP-DATA should have a unique msg reference. Currently 42 is used for all of these. Remember the last reference we used and increment it on the next SMS. Do not track if the reference is still in use a clash is a lot less likely now. First unless SMPP is used only one SMS is delivered at a time, second the transaction space is a lot smaller than the one for the reference.
2013-12-27sms: Fix crash on RLL Establish Request timeouts with active callHolger Hans Peter Freyther1-13/+18
Sylvain pointed out that in the current crash log the transaction we try to read the SMS from is actually a transaction for Call Control. On AMD64 the struct layout is different and that leads to a crash when the CC transaction is in front of the SMS transaction. Look at the trans->protocol to fix the crash. The issue got introduced in 6a3d765bf97349535602ed5b2b55d2093aa18d71 (2010) when I added the SAPI N Reject handling. #0 smpp_sms_cb (subsys=1, signal=4, handler_data=0xbb8270, signal_data=0x7fff33574ea0) at smpp_openbsc.c:284 284 if (sms->source != SMS_SOURCE_SMPP) (gdb) bt #0 smpp_sms_cb (subsys=1, signal=4, handler_data=0xbb8270, signal_data=0x7fff33574ea0) at smpp_openbsc.c:284 #1 0x00007f424e4a094c in osmo_signal_dispatch (subsys=1, signal=4, signal_data=0x7fff33574ea0) at signal.c:105 #2 0x000000000042b070 in send_signal (sig_no=<optimized out>, trans=<optimized out>, sms=<optimized out>, paging_result=<optimized out>) at gsm_04_11.c:125 #3 0x000000000042ccd2 in gsm411_sapi_n_reject (conn=0xec6790) at gsm_04_11.c:1000 #4 0x0000000000408983 in send_sapi_reject (link_id=<optimized out>, conn=<optimized out>) at bsc_api.c:733 #5 rll_ind_cb (_data=<optimized out>, lchan=<optimized out>, link_id=<optimized out>, rllr_ind=<optimized out>) at bsc_api.c:755 #6 rll_ind_cb (lchan=<optimized out>, link_id=<optimized out>, _data=<optimized out>, rllr_ind=<optimized out>) at bsc_api.c:736 #7 0x000000000041f8d2 in complete_rllr (rllr=<optimized out>, type=<optimized out>) at bsc_rll.c:55 #8 0x00007f424e4a03bc in osmo_timers_update () at timer.c:243 #9 0x00007f424e4a069b in osmo_select_main (polling=0) at select.c:133 #10 0x0000000000407394 in main (argc=<optimized out>, argv=0x7fff33575238) at bsc_hack.c:346 (gdb) frame 3 #3 0x000000000042ccd2 in gsm411_sapi_n_reject (conn=0xec6790) at gsm_04_11.c:1000 1000 send_signal(S_SMS_UNKNOWN_ERROR, trans, sms, 0); (gdb) p trans $1 = (struct gsm_trans *) 0xedba80 (gdb) p *trans .... data = 0x1}}, sms = 0x3439323400000003}}} (gdb) p trans->protocol $4 = 3 '\003'
2013-12-27Revert "gsm_04_11: Speculative fix for MT SMS and SAPI 'n Reject"Holger Hans Peter Freyther1-2/+0
Let's revert it and see if we can find the real issue about the sms being invalid. Sylvain has pointed out that we get invoked from a timer and might not have stopped it properly. This reverts commit 80ba9b5dd62cc8bfd10dae2f3b63420ef1e8452d.
2013-12-27gsm_04_11: Speculative fix for MT SMS and SAPI 'n RejectHolger Hans Peter Freyther1-0/+2
I am not sure why it is crashing so this is a speculative fix based on something we already did in 3e9b2ec257bc064b866ce6a2735206dc6131f615. #0 sms_find_pending (smsq=0x2706300, sms=<optimized out>) at sms_queue.c:77 #1 sms_sms_cb (subsys=<optimized out>, signal=4, handler_data=0x26e2270, signal_data=0x7fffdac256c0) at sms_queue.c:396 #2 0x00007fcdea94394c in osmo_signal_dispatch (subsys=1, signal=4, signal_data=0x7fffdac256c0) at signal.c:105 #3 0x000000000042acc0 in send_signal (sig_no=<optimized out>, trans=<optimized out>, sms=<optimized out>, paging_result=<optimized out>) at gsm_04_11.c:124 #4 0x000000000042c8e2 in gsm411_sapi_n_reject (conn=0x2722d30) at gsm_04_11.c:999 #5 0x00000000004085d3 in send_sapi_reject (link_id=<optimized out>, conn=<optimized out>) at bsc_api.c:733 #6 rll_ind_cb (_data=<optimized out>, lchan=<optimized out>, link_id=<optimized out>, rllr_ind=<optimized out>) at bsc_api.c:755 #7 rll_ind_cb (lchan=<optimized out>, link_id=<optimized out>, _data=<optimized out>, rllr_ind=<optimized out>) at bsc_api.c:736 #8 0x000000000041f522 in complete_rllr (rllr=<optimized out>, type=<optimized out>) at bsc_rll.c:55 #9 0x00007fcdea9433bc in osmo_timers_update () at timer.c:243 #10 0x00007fcdea94369b in osmo_select_main (polling=0) at select.c:133 #11 0x0000000000406fbc in main (argc=9, argv=<optimized out>) at bsc_hack.c:346
2013-12-26sms: Move to gsm_7bit_encode_n in the sms sending codeHolger Hans Peter Freyther1-1/+2
Do not rely on the potential wrong gsm_7bit_encode result but use gsm_7bit_encode_n with maximum available space.
2013-10-04sms: Possiqble meamleak fix gsm340_rx_tpdu()Alexander Chemeris1-3/+4
Slight clean up of the code in gsm340_rx_tpdu() and a fix for an unlikely, but possible memory leak there.
2013-03-13SMPP: Implement SMPP Osmocom Estensions on MO-SMS0.13.0Harald Welte1-2/+3
An ESME can now be configured in the VTY to enable osmocom-extensions, which will add vendor-specific SMPP TLVs for RxLev/RxQual/ARFCN/IMEI and transmit power to the SMPP DELIVER-SM message type.
2013-01-13sms: Avoid infinite CP-ERROR/CP-ACK loop with sms.Holger Hans Peter Freyther1-0/+12
The issue can be reproduced by typing the following 9 or more times. OpenBSC> subscriber id 2 sms sender id 2 send bla For some unknown reason the phone sends us a CP-ERROR for a transaction identifier we have allocated and used but don't remember. Due the way we use the SMC/SMR we 'establish' the machine and this results in a CP-ACK being sent out. But the CP-ERROR is not having the content we want for an establish so we send out a RP-ERROR. This will result in a CP-ERROR because the phone does not know the transaction... Avoid the issue by checking the direction of the transaction. If we do not know the transaction and it is supposed to be allocated by us then just ignore it and do not create a new transaction.
2013-01-01libmsc: Allow to set sender id when sending SMS from the VTYSylvain Munaut1-3/+4
Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2012-12-01sms: Kill the linkid as we are using SAPI=3 all the timeHolger Hans Peter Freyther1-5/+3
For GSM (not GPRS) we will never use a SAPI!=3. Simplify the code and remove the link_id=0.
2012-12-01sms: Replaced the SMR process by new implementation in libosmocoreAndreas Eversberg1-85/+98
Rebased, tested and fixed by Holger Freyther. Release the transaction only once the SMC is asking for the release and set the cb's to NULL to catch a use after free early.
2012-12-01sms: Replaced the SMC process by new implementation in libosmocoreAndreas Eversberg1-168/+110
This has been rebased and fixed by Holger Freyther. The change of the debug area was split out in a previous commit and the is_mt was put back into the transaction code. The transaction is now freed from the RELEASE_REQ sent by the SMC layer and not inside the error path. When clearing the SMC instance we also clear the callbacks.
2012-12-01sms: Remove the susbcr_put_lchan logic from the SMS codeHolger Hans Peter Freyther1-22/+0
This should and does happen as part of the trans_free/msc_release_connection code. There is no easy way to determine that the lchan is now 'free' for other things.. Let the transaction code sort this out. This code just needs to make sure that transactions are always freed.
2012-11-24SMPP: add small utility program 'smpp_mirror'Harald Welte1-11/+12
This program binds as ESME transceiver to a SMSC and simply mirrors back all SMS that it receives.
2012-11-24SMPP: Implement support for MO SMSHarald Welte1-1/+25
Each ESME can have a number of prefix-matching routes, or it can be a 'default route' to whcih all otherwise unknown SMS destinations are routed.
2012-11-21sms: Use the DLSMS instead of the DSMS category throughout our codeHolger Hans Peter Freyther1-45/+45
2012-11-21sms: Use the definitions from the libosmogsmHolger Hans Peter Freyther1-227/+5
Use the code that is shipped inside the libosmogsm library. Right now the signature (besides the static) and the implementation is the same. This makes using the libosmogsm SMC code more easy in the near future. For the gsm340_gen_oa we are now using a small wrapper to generate the proper type and numbering plan.
2012-11-16SMPP: build the smpp interface only in case of ./configure --enable-smppHarald Welte1-0/+2
2012-11-16SMPP: Introduce ESME reference coountingHarald Welte1-0/+2
In case a ESME disappears after SUBMIT-SM but before the MT-SMS is delivered (transaction mode), we have to make sure the esme structure still exists.
