2017-06-28wip: a_iface: MSC sided resetPhilipp Maier1-2/+2

2017-06-18osmo-bsc: react on reset requests from MSCPhilipp Maier1-0/+21
The bsc side currently can not receive reset commands from an MSC. This patch adds required functionality to receive a reset command and acknowlege it properly. The effects are the same as with when sending resets (all drop all ongoing calls and sccp connections)
2017-06-18libcommon-cs: genralize a interface reset fsmPhilipp Maier1-2/+2
The AoIP standard also describes an MSC->BSC reset procedure. We currently do not implement it. However, the fsm that is used to issue the reset request from the bsc side is not generalized. This patch generalizes the code in order to be able to use the same code on the MSC side to perform a reset procedure from there.
2017-06-18osmo-bsc: Handle RESET/RESET-ACK properlyPhilipp Maier1-10/+4
Improve the way the BSC executes its RESET/RESET-ACK sequence. Currently only a simple bool variable serves as a state holder. We set this variable to true when we receive the RESET-ACK message. Unfortunately no further checking is done. This patch replaces the old mechanism with a more elaborated implementation which also detects a loss of the connection and makes sure to reconnect properly afterwards. Also the all open connections are closed on connection loss
2017-06-18fixup for: aoip: signal channel type to BSCPhilipp Maier1-60/+168
The channel type and the speech codec element is now signalled to the BSC. The BSC checks both fields and select a codec by its preference. The choosen speech codec and the choosen channel (type) is returned to the MSC. Currently the MSC ignores the return values
2017-06-18osmo-bsc: Negotiate rtp ip address/port with BTSPhilipp Maier1-11/+45
This patch adds the support for the RTP IP-Address/Port assignment. The post communicated via the assignment request is now transmitted via RSL/IPACC to the BTS. The Response containing the RX-Port at the BTS side is communicated back to the MSC. Since we plan to add a private MGCPGW to each BSC, this has to be extended. Currently it only creates a direct connection to the BTS. This will be introduced with a future patch.
2017-06-18WIP: Integrate AoIP into OsmoBSCPhilipp Maier1-4/+17
2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr1-4/+7
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
2017-02-24cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr1-5/+5
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

2016-12-02split subscr_con_allocate()/_free() in bsc_ and msc_Neels Hofmeyr1-1/+1
Rename current subscr_con_allocate() and subscr_con_free to bsc_*, and add two separate msc_subscr_con_allocate() and _free(). The msc_subscr_con_free() ignores all lchan members. In libbsc use bsc_*, in libmsc use msc_*. Change-Id: I3cf7c7cafdf4672ec7b26058bba8a77159855257 Future: there will be distinct subscr conns for libbsc and libmsc.
2016-01-30gsm0408: Provide unique strings for the gsm 04.08 messageHolger Hans Peter Freyther1-1/+1
At Rhizomatica we see that some GSM 04.08 messages are leaked and have no other indication if that is Call Control, SMS or something else.

2014-12-05msc: Add and use gsm_subscriber_groupJacob Erlbeck1-1/+1
Currently every subcriber object directly refers to the gsm_network which contains a flag shared by every related subscriber (keep_subscr). This adds a dependency on gsm_network even if only the function defined in gsm_subscriber_base.c are used. This patch adds a new struct gsm_subscriber_group which contains the keep_subscr flag and a back reference to the network object. The latter is not dereferenced in gsm_subscriber_base.c, so it can safely be set to NULL when only that part of the gsm_subscriber API is being used. It also changes that API to use gsm_subscriber_group instead of gsm_network parameters. Since there are some places where a pointer to the gsm_network is needed but where only a gsm_subscriber is available, a 'net' back pointer is added to the group struct, too. Nevertheless subscr group and network could be separated completely, but this is not the topic of this commit. Sponsored-by: On-Waves ehf
2014-08-08bsc: Add a ctrl command to send a ussdNotify for a callHolger Hans Peter Freyther1-4/+3
Send a non-call related SS message for an active call indentified by the CIC of that call. As an ugly hack the order of the SS release and the invocation are changed. That was necessary for the E71 on a TCH. The time between notify and release was just too short. The right would be to wait for the returnResultLast but this would involve keeping more local state. Let's see how far we get here. It might be necessary to change the order in the other call sites as well.
2014-07-07libbsc, osmo-bsc{, _nat}: Prevent unaligned access when casting TLVP_VALDaniel Willmann1-1/+1
foo = *((uintXX_t *) TLVP_VAL(...) can lead to unaligned access. To prevent that use tlvp_valXX_unal() to get the values.
2013-01-28bsc: Allow to page a BTS that is excluded from the RF lockHolger Hans Peter Freyther1-3/+2
The RF lock excluded BTS was not paged at all. Now forward the paging message to the handler and call a function that will check if this LAC can be paged right now. Introduce a new paging method that allows to page on a dedicated bts, refactor the code to use this method for paging.
2013-01-28bsc: A BTS excluded from the RF lock should be allowed to make a connectionHolger Hans Peter Freyther1-1/+1
When introducing the exclude for the BTS lock the RF stayed up but all connections were immediately released. Optionally pass the BTS as second parameter and check the exclude bit. Tested-with: rf-lock-exclude/RFLockExcludeTest.st

2012-09-11bsc: Hand the msc_connection to the UDT handling, pass it to pagingHolger Hans Peter Freyther1-11/+10
Pass the osmo_msc_data to the paging sub system, change the code to pass the osmo_msc_data instead of network + bsc_msc_conn.

2012-03-16bsc: Create a osmo_bsc_data and embed osmo_msc_dataHolger Hans Peter Freyther1-6/+7
We want to have multiple MSCs but we also have some data that is only present on a per BSC basis. Right now the MSC data is not allocated with talloc, so we have some change in the talloc contexts.
2012-01-27osmo-bsc: Remove hard-coded check for codec preferecne in ASS CMDHarald Welte1-5/+0
When we get an assignment command from the MSC, we no longer have to check statically for certain codecs, as we have a vty-configured list of codecs that is checked just below.
2012-01-20osmo-bsc: correctly parse the TMSI in BSSAP paging from MSCHarald Welte1-5/+3
the TMSI is a uint32_t big-endian value and not a gsm 04.08 mobile identity like the IMSI.
2011-07-12osmo-bsc: Add missing return statement causing CIPH MODE REJHarald Welte1-0/+2
due to a missing return statement, we ran into the 'reject' case of bssmap_handle_cipher_mode(). Due to another bug in libosmocore, the reject message was corrupted (fixed in libosmocore commit 0c83670a595a278b7d1fb7b21b2eacab84d3c031)

2011-03-23Fix build of bsc-nat and GPRS code after include path changeHarald Welte1-2/+2
The last patch changed the osmocore include paths, this fixes some build problems caused by it
2011-03-23src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso1-2/+2
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>
2011-03-03re-structure the OpenBSC directory layoutHarald Welte1-0/+548
The new structure divides the code into a number of libraries for the BSC core functionality, MSC core functionality, Abis transport, TRAU and other bits. This doesn't introduce any functional code change but simply moves around files and alters Makefile.am accordingly. Next step would be to disentangle a lot of the inter-library dependencies and make the individual bits of code more independent.
