2016-12-02bsc vty: rename show_net_cmd to bsc_show_net_cmdNeels Hofmeyr1-2/+2
Future: there will be an MSC-land show-net-cmd, so rename to something with bsc in its name. Change-Id: Ifb86698cd57a09f03b935b6d3fcea87eff4cd397
2016-12-02move to libcommon-cs: network VTY that isn't BSC-specificNeels Hofmeyr3-194/+211
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.

2016-12-02move to libcommon-cs: global vty gsm_network pointerNeels Hofmeyr3-17/+32
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.

2016-12-02global gsm_network: move allocation further upNeels Hofmeyr2-23/+25
Now that bsc_network_alloc() is separate, move it to before the VTY init (a subsequent patch will pass the gsm_network instance as a parameter to vty_init()). bsc_hack.c: drop the comment that says about the VTY init: "This needs to precede handle_options()" -- it is not accurate. Actually move the handle_options() above both vty_init() and the bsc_network_alloc() calls, to be able to decide which mncc callback to pass to bsc_network_alloc. It would make sense to set this later on, but that would require further refactoring of the bsc_network_init() and gsm_network_init() signatures, so not in this patch.

2016-12-02split bsc_bootstrap_network() in alloc and configNeels Hofmeyr4-13/+33
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.

2016-12-02sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counterNeels Hofmeyr6-43/+20
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

2016-12-02factor out gen of USSD notify and release complete to libosmocoreNeels Hofmeyr10-38/+64
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() functions, since there will be distinct subscriber connection structs. Rename to msc_send_ussd_notify() and msc_send_ussd_release_complete(), and add the same in libbsc with bsc_ prefix in new file gsm_04_80_utils.c. In preparation of this patch, the message generation part of these functions has been added to libosmocore as gsm0480_create_ussd_notify() and gsm0480_create_ussd_release_complete(). Use these. Adjust all libmsc and libbsc callers according to use the msc_* or bsc_* implementation, respectively. Change-Id: I33a84e3c28576ced91d2ea24103123431f551173
2016-11-28IuPS: properly update ra_id on GMM Attach RequestNeels Hofmeyr1-4/+2
For new MM contexts, the ra_id was correctly obtained from the ue_ctx, but in case an MM ctx is re-used and the ra_id changed, the new ra_id was not copied to the MM context; instead, the ra_id was overwritten with uninitialized data. Always initialize the local ra_id variable from the ue_ctx->ra_id for Iu connections; it is used further below to update the ctx->ra_id. For the case of a brand new Iu MM ctx, the ctx->ra_id then gets initialized a second time. We could technically drop the init in sgsn_mm_ctx_alloc_iu(), but it doesn't hurt either way.

2016-11-27sndcp: fixup for coverity scan defect CID 149097Philipp2-0/+2
Coverity scan detects a Null pointer deref (FORWARD_NULL) in gprs_sndcp_comp.c: 67 in gprs_sndcp_comp_create(). The reason for this is that gprs_sndcp_dcomp_init() and also gprs_sndcp_pcomp_init() rely on the comp_entity->algo algo flag. If the program logic is correct a null pointer deref should never occur. This commit adds OSMO_ASSERT() statements to ensure a null pointer deref is catched if if the ...comp_init() functions are used with incorrect parameters.

2016-11-24move to libcommon-cs: gsm48_create_mm_serv_rej(), gsm48_create_loc_upd_rej()Neels Hofmeyr3-34/+34
Used by libbsc, libmsc as well as osmo-bsc and osmo-bsc_nat. Moving gsm48_create* to libcommon-cs affects linking of osmo-bsc_nat, resulting in undefined references to gsm48_extract_mi() and gsm48_paging_extract_mi(); fix that by placing libfilter.a left of libbsc.a upon linker invocation.

2016-11-24move to libcommon-cs: net init 3: actual moveNeels Hofmeyr15-35/+84
Reincarnate gsm_network_init() as the parts not specific to libbsc. Move from bsc_network_init() those bits that are not BSC specific (and useful for upcoming osmo-cscn). Add libcommon-cs to all linkages that use gsm_network_init(). Note: the only requirement to allow linking gsm_network_init() without libbsc is to keep the call to gsm_net_update_ctype() out of libcommon-cs. The other items are kept out of libcommon-cs because it makes sense semantically. But the separation is not strong in that the BSC specific data members are of course still omnipresent in struct gsm_network. If bsc_network_init() is not called, these are not initialized properly -- for now no users of uninitialized members exist. So this is just a first step towards a sensible split of the BSC and MSC gsm_network structs. The long term aim should be to have entirely separate structs with some common general items.

2016-11-24move to libcommon-cs: net init 2: move bsc_network_init decl to new .hNeels Hofmeyr9-8/+17
bsc_network_init() is more fit to live in a BSC specific header, move it to new common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network in the future. Adjust header includes across the board. Particularly, fix abis_nm.h by explicitly including gsm_data.h: it so far relied on other headers to do that, which now is no longer always given.

2016-11-24move to libcommon-cs: net init 1: rename to bsc_network_initNeels Hofmeyr7-8/+10
The gsm_network_init() function initializes a whole lot of BSC specific stuff. Aiming to move some of it to libcommon-cs, first rename it to bsc_network_init(). This will retain the BSC specific stuff when the move is done. Adjust all callers. Future: osmo-cscn will call the more generic part and not the BSC specific part.

2016-11-24define mncc_recv_cb_t to avoid code dupNeels Hofmeyr5-7/+13
Put mncc_recv_cb_t in common_cs.h to avoid header include complications: if placing right above struct gsm_network, one must include gsm_data.h to use mncc_recv_cb_t as function parameter in a header, which will include gsm_data_shared.h, which will include common_cs.h (future knowledge). Since I will need to use mncc_recv_cb_t in common_cs.h, including gsm_data.h from there would introduce an #include loop. Avoid that and define mncc_recv_cb_t in common_cs.h to begin with.

2016-11-18ussd: Add band-aid for interrogationSSHolger Hans Peter Freyther3-12/+20
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.

Ericsson has introduced a propritary format to issue the S13 BCCH information. Normally the system info type field for SI13 would be encoded as 0x28. Ericsson encodes that field as 0x02 and ads a bcch mapping parameter, (IEI=F2) This patch sets the BCCH mapping to 0x00 (=BCCH Normal) statically (0xF200) The new constands are added to libosmocore, see commit: f0f9c8c29daaefbf9cff19177ade4a13ffb2e36c Change-Id: Ie0900f9b810744172b3090ce1b0ef7b7a1132946

2016-11-10OM2000: for TS conf of dyn TS, always send TCH/F chan combNeels Hofmeyr1-5/+1
When OM2K sets up the timeslots with the BTS, the dynamic channel state is not yet resolved to any particular pchan type. Instead of using the dyn state, always advertise dynamic timeslots as pchan2comb(TCH/F). In the past, the Ericsson dynamic timeslots were handled as pchan type TCH/F_PDCH. This is a mistake, as this pchan type is intended for the ip.access dynamic PDCH way of dynamic channels. In any case, in the initial state of this pchan type, the timeslot was initialized as pchan2comb(TCH/F) because the ts->flags do not reflect an active PDCH yet. In short, this patch does not change the behavior of TCH/F_PDCH timeslots, only clarifies it. It would in fact make sense to disallow use of TCH/F_PDCH for OM2K, but that should probably be a separate patch. The proper pchan to use for Ericsson dynamic timeslots is TCH/F_TCH/H_PDCH. These do not use ts->flags, but ts->dyn.* as state, which first reflects pchan_want == pchan_is == GSM_PCHAN_NONE. Hence the timeslot was initialized by OM2K as pchan type zero, which is unknown / invalid. So, instead of using pchan_is, which is not yet reflecting anything meaningful, always initialize as TCH/F chan comb, as Ericsson hardware apparently expects it.
