2017-05-20libmsc: Map SMPP command status to GSM 04.11 causeKeith3-7/+41
Send SMS RP ERROR with a failure cause that relates to the status returned by the ESME in the deliver_sm_resp. Actual mapping array is limited as most phones I tested don't seem to care about the failure cause anyway, although some will display a different notification for GSM411_RP_CAUSE_MO_NUM_UNASSIGNED Change-Id: I61fb2d9ef4f2d2eabdc49b53d9966ad328d15e51
2017-05-12fix subscriber random extension allocation rangeNeels Hofmeyr1-4/+4

2017-05-12fix VTY parsing: subscriber-create-on-demand randomNeels Hofmeyr1-1/+1
Fix parsing of the 'subscriber-create-on-demand random' VTY: atoi() is not enough to include the specified range of 1-9999999999. Use atoll() instead to ensure a large enough number space also on 32bit systems. (Note: for me, atoll() truncates at 32 bit when <stdlib.h> is not included.) Add a VTY regression test for this.

2017-05-08libmsc: send RP-ACK to MS after ESME sends SMPP DELIVER-SM-RESPPablo Neira Ayuso4-17/+174
Hold on with the GSM 04.11 RP-ACK/RP-ERROR that we send to the MS until we get a confirmation from the ESME, via SMPP DELIVER-SM-RESP, that we can route this sms somewhere we can reach indeed. After this change, the conversation looks like this: MS GSM 03.40 SMSC SMPP 3.4 ESME | | | | SMS-SUBMIT | | |------------------->| | | | DELIVER-SM | | |---------------->| | | | | | DELIVER-SM-RESP | | |<----------------| | GSM 04.11 RP-ACK | | |<-------------------| | | | | Before this patch, the RP-ACK was sent back straight forward to the MS, no matter if the sms can be route by the ESME or not. Thus, the user ends up getting a misleading "message delivered" in their phone screen, when the message may just be unroutable by the ESME hence silently dropped. If we get no reply from the ESME, there is a hardcoded timer that will expire to send back an RP-ERROR to the MS indicating that network is out-of-order. Currently this timer is arbitrarily set to 5 seconds. I found no specific good default value on the SMPP 3.4 specs, section 7.2, where the response_timer is described. There must be a place that describes a better default value for this. We could also expose this timer through VTY for configurability reasons, to be done later. Given all this needs to happen asyncronously, ie. block the SMSC, this patch extends the gsm_sms structure with two new fields to annotate useful information to send the RP-ACK/RP-ERROR back to the MS of origin. These new fields are: * the GSM 04.07 transaction id, to look up for the gsm_trans object. * the GSM 04.11 message reference so the MS of origin can correlate this response to its original request. Tested here using python-libsmpp script that replies with DELIVER_SM_RESP and status code 0x0b (Invalid Destination). I can see here on my motorola C155 that message cannot be delivered. I have tested with the success status code in the SMPP DELIVER_SM_RESP too. Change-Id: I0d5bd5693fed6d4f4bd2951711c7888712507bfd

2017-03-31LU counters: count completion and failure, not messages sentNeels Hofmeyr2-16/+34
From a human admin viewpoint it doesn't make sense to count the messages sent: When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect the MS to respond with a TMSI Realloc Complete message. When that fails to come through, the LU actually ends in failure, even though a LU Accept was sent. If a conn breaks/vanishes during LU, we cancel the LU without sending any reply at all, so the failed LU would not be counted. Instead, count Location Updating results, i.e. completion and failures. (With the new VLR developments, LU counters need to be triggered in completely different places, and this patch prepares for that by providing sensible counters.)

2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr3-11/+62
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC subscriber: struct bsc_subscr. Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no longer have a backpointer to gsm_network (used to be via subscr->group). Create a separate logging filter for the new BSC subscriber. The implementation of adjusting the filter context is added in libbsc to not introduce bsc_subscr_get/_put() dependencies to libcommon. During Paging Response, fetch a bsc_subscr from the mobile identity, like we do for the gsm_subscriber. It looks like a duplication now, but will make sense for the VLR as well as for future MSC split patches. Naming: it was requested to not name the new struct bsc_sub, because 'sub' is too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast to type, relatively short, unambiguous, and the naming is consistent. Add bsc_subscr unit test. Related: OS#1592, OS#1594 Change-Id: Ia61cc00e8bb186b976939a4fc8f7cf9ce6aa3d8e
2017-03-02subscriber conn: add indicator for originating RANNeels Hofmeyr1-1/+1
Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but also for libvlr to decide between GSM or UMTS Auth. Until actual Iu support is merged to master, this indicator will aid VLR unit testing. At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to clearly distinguish the names if we want to add it, explicitly name the ones we have RAN_GERAN_A and RAN_UTRAN_IU.

2017-02-28silent_call: remove unfinished fuzzer interfacePhilipp Maier2-0/+6
Remove the fuzzer interface that was partially implemented in gsm_04_08.c and silent_call.c is causing problems when an SMS is sent during an active silent call. The reason for this is that gsm0408_dispatch() in gsm_04_08.c would decide to rout all uplink traffic to silent_call_rx() in silent_call.c. silent_call_rx() is a stub function that discards the data. This patch removes the fuzzer interface code by placing ifdefs around it, so that it can be re-activated by experimentators. Change-Id: Id500197d58663b3f4b1756136343670388b0a4bc

2017-02-22logging: use central filter and ctx consts from libosmocoreNeels Hofmeyr2-9/+9

Some of these will change to _BSC_SUBSCR once struct bsc_subscriber is introduced, and later on, struct gsm_subscriber will be replaced by vlr_subscriber so that the names will match.

2017-02-19subscr_update_expire_lu(): fix (obscure) segfaultNeels Hofmeyr1-0/+10
To be paranoid, catch a NULL subscriber and/or bts in subscr_update_expire_lu(): print an error log and avoid segfault. (I'm not sure this would really happen in a normal situation.) During aggressive testing of Paging timeout, I came across this segfault in msc_release_connection() when conn->expire_timer_stopped is set but conn->subscr is NULL, at the subscr dereference after: if (conn->expire_timer_stopped) subscr_update_expire_lu(conn->subscr, conn->bts); I brought this situation about by a fabricated Paging fault, i.e. in gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at all. Thus conn->subscr is still NULL when expire_timer_stopped is 1. When looking at CM Service Request handling, the conn->subscr is set before setting expire_timer_stopped = 1, which is a saner thing to do. But without my mad 'return 0', there is in fact no way to have a NULL subscriber there. It looks like all other code paths already do the same, but it's not that obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of NULL conn->subscr, and while at it catch NULL bts as well. Change-Id: I430dd952b2b928bea7f8360f1e01bb3cccb0a395

2017-02-06gsm_04_08: implement parsing of UMTS Auth responsesNeels Hofmeyr1-5/+221
Parse the longer UMTS res from the extended Auth Response Parameter IE. Parse the R99 Authentication Failure and AUTS in case of cause GSM_REJECT_SYNCH_FAILURE which indicates a SQN re-sync request. Both still end in 'not implemented' error logs, which are the places where the upcoming VLR that supports UMTS AKA will integrate.

2017-02-03gsm0408_rcv_cc: guard against NULL subscriberNeels Hofmeyr1-0/+5
Check conn->subscr against NULL. gsm0408_rcv_cc() dereferences many conn members without checking presence: the bts and lchan members may be expected to be NULL in the ongoing MSC split and 3G developments. But the conn->subscr is initially NULL, so an MS sending a CC message before something like a LU or CM Service Request will result in a segfault. Prevent that. Note: the upcoming VLR will be more restrictive on what messages are processed, this is a "backport" to the situation on current master. Change-Id: If067db7cc0dd3210d9eb1da15be6b637795a3ecf

Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS structures will be available on the MSC level. To simplify, drop the ability to manage several time zones in a core network and place the time zone config on the network VTY level, i.e. in gsm_network.

2016-12-02reinvent connection_for_subscr() and move to libmscNeels Hofmeyr1-0/+14
Implement connection_for_subscr() from a completely different angle: instead of looking up lchans in bts structs, look up the subscriber in the global list of gsm_subscriber_connection. static lchan_find() is thus obsoleted. All callers of connection_for_subscr() live in libmsc, so move to libmsc. The move and edit are done in a single commit since the old and new implementation have nothing in common. Future: osmo-cscn will use this, without bts being present. Remove implementation of connection_for_subscr() from channel_test.c -- it is possible that the abort() in there was intended for a regression test, but actually it seems the implementation was merely added for linking reasons, and the abort() added to guard against the NULL return value: no comment nor the commit log indicate that the abort() is test critical; the addition was the only change in channel_test.c for that commit; at the same time a connection_for_subscr() call was added in libmsc.

2016-11-18ussd: Add band-aid for interrogationSSHolger Hans Peter Freyther2-10/+18
This is a speculative change for interrogateSS and by not answering the request the radio connection would remain open long. The SS/USSD code is from a time where none of knew much about GSM. We do not support SS but should reject it. We have checked for an empty string in the text field to guess if it is a result/release to not send more information. The right way forward is to decode the ASN1 into the fields REQUEST/RESULT(last). Fix an issue and make the code worse. Assume ss_code > 0 to see if this is a interrogate invoke. The issue is that code 0 is a well defined value but unlikely to be used. MAP ASN1 definition: SS-Code ::= OCTET STRING (SIZE (1)) -- This type is used to represent the code identifying a single -- supplementary service, a group of supplementary services, or -- all supplementary services.

2016-11-02mncc_builtin: Properly reject DTMFlynxis/masterHarald Welte1-0/+2
As per TS 23.014, a GSM MSC must implement mobile-originated DTMF generation. We gate the DTMF signalling messages to MNCC, and expect the external MNCC handler to deal with it. However, the internal MNCC handler simply ignored such singalling messages, rather than rejecting DTMF altogether. It turns out failure to respond to START DTMF will cause some phones to behave in interesting ways, particularly with modem firmware v6.01.00, see https://osmocom.org/issues/1817). In this case the phone is not able to release the call as the pending response to the START DTMF is probably keping a reference or lock of some sort.

gsm0408_dispatch() is the main entry point for receiving data from the BSC/RNC level, so make sure callers pass valid pointers before using them all the way down the code path (related to CID#93769, a fix before this was refactored). For unknown/unimplemented packet discriminators, make sure to return error codes. Change-Id: Ieec39c74a53ef4dfa971dd935c8c9aa60fef58c1
