Postfix the ran type to clarify the purpose. Because of the new support of the Iu ran type, there are 2 functions to allocate a mm ctx. For Iu it's sgsn_mm_ctx_alloc_iu(). For gb it should be named in the same way. Change-Id: Ic49009e8c20c12308855e1409c09004698c79b95

2017-01-27rsl: Fix dropping of LAPDm UA message.Minh-Quang Nguyen1-0/+2
In some cases, when successive mobile originated calls are made, the LAPDm UA message gets lost because the channel is relased to early. Too overcome the problem we do not send release indications immediately. Instead a flag will be set and the message stored and sent on the next TCH-RTS-IND. This commit adds the required flag and the msg-buffer to struct gsm_lchan. See also coresponding change in osmo-bts.git: Change-Id Ie4f70c75f0137b4bd72d579b3a32575bac2fca38 This patch is is a slightly improved/reformatted version of: https://gitlab.com/nrw_noa/osmo-bts/commit/95d1f15ad108c1c1869c1965144acd64c1395d8c Change-Id: I15fc1ef8e9e83f009bde96de9a8e95702cffbce6
2017-01-26Implement VTY configuration to control Early Classmark SendingHarald Welte1-0/+1
The SI3 rest octests contain a flag that indicates if early classmark sending is allowed in this cell or not. So far we always set this to one, now it is configurable using the 'early-classmark-sending' command at the VTY node. Change-Id: Ia0b1cc5ab45673f3da70c59ae8917eba343f9862

2017-01-23Prevent segfault in range encodingMax1-0/+4
* Explicitly check when ARFCN array split is impossible and return gracefully instead of using negative index. * Separate range encoding into generic function and use it for all SI-related things. * Propagate the error into that function and to its callers. * Add separate test-case for the segfault previously triggered by this bug.

2016-12-23sndcp: Allow empty SNDCP-XID indicationsPhilipp1-6/+8
In some rare cases the modem might send a xid indication that does not contain anything except the version number field. The sgsn ignors such SNDCP-XID indications by stripping the entire field from the response. We found a modem in the wild that started to act problematic when the empty SNDCP-XID was missing in the response. This patch changes the XID negotiation behaviour in a way that if a modem should send empty SNDCP-XID indications, the reply will also contain an empty SNDCP-XID indication. Apart from that the SNDCP-XID version number is now parsed and echoed in the response. This ensures that we always reply with the version number that the modem expects. (The version was 0 in all cases we observed so far) Change-Id: I097a770cb4907418f53e620a051ebb8cd110c5f2 Related: OS#1794

2016-12-13oap: rename public API from oap_ to oap_client_Neels Hofmeyr3-17/+21
Mainly to differentiate the OAP messaging API (osmo_oap_ in libosmocore) from the OAP client. This is in preparation for moving the oap client to libcommon, which is in turn preparation for libvlr. Add the osmo_ prefix, as all public Osmocom API should have. We also have OAP messages code in libosmocore, so clarify by naming this osmo_oap_client, and by also renaming the oap_test to oap_client_test. This reshuffling will allow an easy move of OAP to libosmocore if we should want to do that. A number of patches will follow up on this.

This is in preparation for moving gsup to libcommon, which is in turn preparation for libvlr. Related: OS#1592 Change-Id: I9c95d00f1a9420887a44c938b1d0ee3e20586f4c
2016-12-13gprs_gsup_client*: remove the gprs_ prefixNeels Hofmeyr2-21/+22
Make sure everything is named gsup_client_ / GSUP_CLIENT_. Rename static gsup_client_send() to client_send() to avoid clash with public gprs_gsup_client_send() being renamed to gsup_client_send(). This is in preparation for moving gsup to libcommon, which is in turn preparation for libvlr. libvlr and osmo-sgsn will use the same GSUP client code. A number of patches will follow up on this, also for the the OAP client. Related: OS#1592 Change-Id: I57433973b1c4f6cc1e12e7b1c96b5f719f418b51
2016-12-13Revert "Support Deactivate PDP Context Request from network"Neels Hofmeyr1-2/+0
This reverts commit 1611df5226199da2bf2fba3d22d93cc1a6c6c777. This is due to a segfault introduced to the asan build only. See: http://lists.osmocom.org/pipermail/openbsc/2016-December/009966.html Subject: new sanitizer breakage: SIGSEGV in sgsn_create_pdp_ctx() Date: Tue Dec 13 12:08:32 UTC 2016 Change-Id: Ic926c0e6778947b516994822e3a21d4fde25bb02
2016-12-12Support Deactivate PDP Context Request from networkPravin Kumarvel1-0/+2
Enable Deactivate PDP context based on the IMSI of the subscriber. When there are PDP contexts present for a MM context, PDP context will be deactivated along with GMM Detach(MM context deletion). If there are no PDP present, MM context will be deleted to avoid further PDP context request from the MS. Test cases is added to check this functionality.

2016-12-09lchan release in error state: SACCH deact only for SACCH pchansNeels Hofmeyr1-0/+1
This is useful particularly in case where we deactivate PDCHs which don't have a SACCH associated. The existin code would always attempt to deactivate a SACCH even in those cases, leading to the BTS responsding with related error messages. Change-Id: Iaf46782329b38ba8f3d438e6c75c2d467b852734
2016-12-02gsm_subscriber_connection: mark BSC specific itemsNeels Hofmeyr1-6/+6
This is intended to prepare for splitting gsm_subscriber_connection into BSC and MSC specific structs, to make the splitting patch more readable. Change-Id: Ib9666225fb9bfec2cf1e364343560571869fe6a7
2016-12-02split subscr_con_allocate()/_free() in bsc_ and msc_Neels Hofmeyr1-2/+5
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.
2016-12-02Move timezone settings up to network levelNeels Hofmeyr2-8/+14
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. If we are going to re-add fine grained time zone settings, it should probably be tied to the LAC. Adjust time zone VTY config code (to be moved to libcommon-cs in subsequent commit). Adjust time zone Ctrl Interface code. Change-Id: I69848887d92990f3d6f969be80f6ef91f6bdbbe8
2016-12-02move to libcommon-cs: network VTY that isn't BSC-specificNeels Hofmeyr1-1/+2
Keep only BSC specific bits of the 'network' VTY node in bsc_vty.c, move more general VTY commands to common_cs_vty.c. Add arg to common_cs_vty_init() to pass a config_write_net() function. Pass a libbsc specific config_write_net() function. Future: upcoming omso-cscn will re-use the VTY bits moved to libcommon-cs and pass a different config_write_net() function. Change-Id: I871b7b32a0c56fdce983e409cf244ec487d24e71
2016-12-02move to libcommon-cs: global vty gsm_network pointerNeels Hofmeyr1-0/+5
Move gsmnet_from_vty() and the bsc_gsmnet global to common_cs_vty.c. Rename bsc_gsmnet to vty_global_gsm_network and make it static to common_cs_vty.c, to clearly mark the global variable for VTY use only. Introduce common_cs_vty_init() to set vty_global_gsm_network. Change-Id: I26c5c47de08f899b896813d09612d5cb2f8e42d6
2016-12-02split bsc_bootstrap_network() in alloc and configNeels Hofmeyr1-1/+2
For patch clarity, keep some code dup to be removed in a subsequent patch. In the same sense don't change the fact that mncc_sock_init()'s return value is ignored. The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY, and a future patch will "hide" that global in a vty .c file. In a nutshell, I want to - first allocate a gsm_network, - then initialize the VTY passing the gsm_network pointer, - and then read the config file using the initialized VTY. So far, bsc_bootstrap_network() allocates the gsm_network and reads the config file right away, which only works by sharing the extern bsc_gsmnet pointer, which I would like to uncouple. Change-Id: I480a09a31a79766ad07b627dd5238b7e37f3be7a
2016-12-02sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counterNeels Hofmeyr1-1/+1
libbsc and libmsc will have separate subscriber connection structs. Hence don't rely on gsm_subscriber_connection, but work on a direct pointer to the counter for the next RP reference. The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop the entire file. Change-Id: I2a2e9ba6a981a385d1f8f07acbe03536ffed0072
