2017-08-21Revert "factor out & introduce struct gsm_encr, in common_cs.h"Neels Hofmeyr2-11/+6
This reverts commit ac1f1436e9d380f632dd850fcd253d3480f0fc2d. common_cs.h added to gsm_data_shared.h was a mistake, i.e. I added the dependency by accident. Including common_cs.h in the debian installation may have seemed like the logical consequence but was not intended. AFAICT for osmo-msc, the need for struct gsm_encr is obsoleted by libvlr, gsm_encr will only be used in osmo-bsc and can just stay an inline struct.

2017-08-13libcommon: Fix log output for bts>0.Alexander Chemeris1-1/+1
Fixes regression probably introduced in c696cc28. For bts>0 logging doesn't show bts number correctly when printing lchan identification string - it will always show it as "bts=0". The reason for this is that the identification string is cached before bts->nr value is set to a proper value. This patch sets bts->nr as part of the first step of the bts structure initialization, before caching happens thus making sure the cached identification string is cached with the correct values.

2017-08-09libmsc: add support for SMPP delivery receiptsPablo Neira Ayuso1-0/+1
If the mobile phone requests a status report via SMS, send a DELIVER_SM with esm_class = Delivery Receipt to ESME to indicate that the SMS has been already delivered to its destination. MS GSM 03.40 SMSC SMPP 3.4 ESME | | | | SMS-DELIVER | | |<----------------------------| | | GSM 04.11 RP-ACK | | |---------------------------->| | | | DELIVER-SM | | | esm_class = Delivery Receipt | | |------------------------------->| | | DELIVER-SM-RESP | | |<-------------------------------| | | | This patch implements "Appendix B. Delivery Receipt Format" as specified in the SMPP 3.4 specs. This string is conveyed in the SMS message as data, and it is only meaningful to the ESME, for logging purposes. The "submit date" and "done date" are not yet set, and other fields are just sent with dummy values, so they are left to be finished as future work. The new SMPP TLV tag TLVID_user_message_reference is added to the SMPP messages inconditionally now since this information is required by delivery-reports to associate the status-report with the original SMS.

2017-07-20GSM timers: User reasonable defaults; don't save if equal defaultHarald Welte1-2/+10
A number of the GSM timers (including T3109) had no reasonable default values if not specified in the VTY / config file. Together with unconditional writing to the config file, this created config files with a persistent setting for important timers as '0'. To make things worse, many of our example cofig files suffered from the same problem. Let's avoid this from happening by * having reasonable defaults if nothing specified in the config file * conditionally savingg timers only if they differ from default * reject any timer values that state zero during start-up (see previous commit) Change-Id: Iaac0bfca423852b61d8b9eb1438157ef00d0d8c8 Closes: OS#2380

2017-06-18Add vty command "radio-link-timeout infinite" for uplink rx testingHarald Welte3-14/+5
When we are performing Rx sensitivity testing on a BTS, we want to deactivate the connection failure criterion / radio link timeout, i.e. no matter how many SACCH frames in uplink are failed to decode, the BTS should never close the channel. OsmoBTS Change-Id I736f21f6528db5c16fa80cdb905af20673797be5 covers a way how this behavior can be requested from the BTS via an OML attribute. This patch adds support to the BSC to actually set that attribute. Do not use this in production networks, as the BTS will keep open radio channels indefinitely even if the phone is gone and no longer transmitting anything. This is a pure testing feature.

Since commit b4999b60d48bcbb5aa575973d068e07ab672e095 we created PCU sockets at hard-coded paths in the filesystem by default for all BTSs. This is inflexible and prevents the use of multiple BSC instances on a single filesystem, or the placement of the sockets in a more secure location than /tmp. The new approach with this patch is that * no PCU sockets are created by default * only for those BTSs where a 'pcu-socket' is configured via VTY, the socket will actually be created Change-Id: Ie9079470584777dcc31f85f9bf0808f479156ccb Closes: OS#2293

2017-05-08libmsc: send RP-ACK to MS after ESME sends SMPP DELIVER-SM-RESPPablo Neira Ayuso2-0/+10
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

2017-04-28Prepare for extended SI2quater supportMax3-3/+10
Supporting SI2quater as per 3GPP TS 44.018 will require chnages to the way System Information is stored because it uses 1:n instead of 1:1 mapping between SI type and generated SI content. This should not affect other SI types though. To facilitate this transition: * convert the code to always use GSM_BTS_SI helper instead of accessing buffer directly * make helper more robust by adding extra parenthesis * add similar helper for gsm_lchan * add function estimating number of SI2quater message to hold configured number of (U|E)ARFCNs * add SI2q index/count fields and pass them to rest_octets generator explicitly * internalize buffer access in generate_si* functions Change-Id: I74e4e3cb86364cec869a1472a41b4a95af0d50dd Related: RT#8792

2017-03-31LU counters: count completion and failure, not messages sentNeels Hofmeyr1-4/+4
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 Hofmeyr7-11/+75
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

2017-02-28silent_call: remove unfinished fuzzer interfacePhilipp Maier1-0/+3
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

2017-02-25add struct gprs_subscr, separating gprs from gsm_subscriberNeels Hofmeyr5-10/+44
Prepare for replacing gsm_subscriber with vlr_subscriber. vlr_subscriber will not make sense to be used in gprs, so have a dedicated GPRS subscriber struct. (Could change if the gprs code were to use libvlr; is currently independent). Related: OS#1592 Change-Id: Ia8b391ee009c8545763cba04505be3947835120e
2017-02-24cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr4-13/+13
With the OsmoMSC program coming up, the name osmo_msc_data becomes even more confusing than it already is. Clearly indicate it as libbsc's data of a remote MSC by prefixing with bsc_. Also, the Osmocom community has in the meantime agreed to have the osmo_ prefix only in libosmocore, to avoid naming conflicts in case things are moved there. So while renaming anyway, also drop the osmo_ prefix. Change-Id: I0dfbcb7d1a579211180f71319982820d8700afab
