2017-12-19iu client: store multiple LAC,RAC per RNC = fix paging for multiple RNCNeels Hofmeyr1-86/+131
Introduce a list of LAC+RAC entries for each RNC, hence allow serving more than one LAC per OsmoHNBGW. iu_client is used by OsmoMSC and OsmoSGSN, both will be able to page successfully in a setup with multiple LACs (read: multiple hNodeB) connected to an OsmoHNBGW. Ensure that each LAC,RAC is registered with at most one RNC Id. If a LAC,RAC shows up on a different RNC Id than before, move it over to the new RNC Id. Future patches should probably add: * timeouts of RNC Id / LAC,RAC validity, to remove unused entries. * VTY/CTRL commands to introspect which RNCs and LAC,RACs are listed. * VTY/CTRL commands to remove RNC Id / LAC,RAC entries.

2017-11-24osmo-hnbgw: auto-config local and remote PCs if omittedNeels Hofmeyr1-5/+15
The current default point-code for OsmoMSC is 0.23.1 and for OsmoSGSN 0.23.4. See https://osmocom.org/projects/cellular-infrastructure/wiki/Point_Codes. Before this patch, osmo-hnbgw requires a cs7 config and explicit point-codes for MSC and SGSN as well as a local one. Provide default config if none is provided: Use above default point-codes if no MSC and/or SGSN address are provided. Also create a default cs7 instance with local PC 0.23.5. This allows completely omitting cs7 instance and SCCP addresses from osmo-hnbgw.cfg in a single-box setup. Change-Id: I056547f26858d3ad52e66a15f7a4273dcc300e97

In Change-Id I6a3f7ad15be03fb94689b4af6ccfa828c25f45c0 we introduced the somewhat arguable combination of Iu code in libosmo-ranap. This Iu code uses functions provided by libosmo-sigtran. However, at the time it was overlooked to explicitly link libosmo-ranap against libosmo-sigtran, which caused linking failures of programs using libosmo-ranap, such as the unit tests included in this package.

2017-08-13iu_client: derive local SCCP addr from sccp instanceNeels Hofmeyr2-27/+3
ranap_iu_init() is passed an sccp instance that has a local primary point code. Use this primary PC by default as the local address for IuCS and IuPS clients. Remove the current vty command 'iu local-address point-code PC': - It is possible that we would like to configure a differing local point code at some point; this should then happen via sccp address book entries, not parsing PC directly. - Obtaining the local PC from the SCCP instance makes this command obsolete for all setups we're currently aiming at: one local PC per SCCP instance. - There are vty doc failures in this vty command, which cause osmo-msc and osmo-bsc vty test failures; rather than fixing this, let's drop it entirely until we see a need for it (and then do it properly with the address book). Cosmetic: prefix the local static variable with g_* like g_sccp and g_scu and define it in the same place. No default values are needed anymore, it gets overwritten in ranap_iu_init().

2017-07-31move openbsc.git's iu.h, iu.c, iu_vty.c here as iu_clientNeels Hofmeyr5-1/+999
To help split openbsc.git to separate MSC and SGSN repositories, place the common Iu interface related code here in libosmo-ranap. Also apply various improvements while moving (from intermittent code review). The code depends on libosmo-ranap tightly. One reason to want this separate from libosmo-ranap could be that it uses libosmo-sigtran, accepting an sccp instance. However, including in libosmo-ranap is the simplest way to go. The osmo-iuh build depends on libosmo-sigtran anyway because of OsmoHNBGW, and all current users of libosmo-ranap also naturally link libosmo-sigtran already. Apply prefix ranap_iu_ and RANAP_IU_ to allow smooth transition from the openbsc.git iu_ to the libranap ranap_iu_ implementations. Prune unneeded #include statements. Instead of sccp_addr, store an rnc pointer in the ue_conn_ctx. To facilitate, also: - Move iu_rnc struct to iu_client.h (as ranap_iu_rnc). - Instead of sccp_addr, pass rnc to ue_conn_ctx_alloc(). - Pass a local struct new_ue_conn_ctx containing the sccp_addr and conn_id up the RANAP handling stack in case of an InitialUE message. - Separate the InitialUE message handling from cn_ranap_handle_co(), by moving to new and separate cn_ranap_handle_co_initial(), so we can still pass a looked-up ue_conn_ctx to all other cn_ranap_handle_co() code paths. - Allocate the ue_conn_ctx only in ranap_handle_co_initial_ue(), not as early as before. Note that we are not actually ever using the rnc pointer now present in ue_conn_ctx. It could be used for more concise paging, to first page only the RNC where we last saw the subscriber. So far we page all matching LAC/RACs. Tweak error logging: use __func__ instead of writing the function names as string constants. In iu_client_vty.c: - Move the asn.1 debug commands from logging over to the iu node. They are not specific to the logging target. They could qualify for an entirely separate 'asn1' root node, but for simplicity place under 'iu'. - Add the 'asn1' commands to ranap_iu_vty_config_write(), so far missing. - remove the legacy "net." from a VTY error message, it is not known which name the parent node of 'iu' has.

2017-07-05migrate osmo-hnbgw to libosmo-sigtran's SCCP/M3UANeels Hofmeyr10-134/+133
libosmo-sigtran now has a "proper" SCCP/M3UA stack, so we can make our hnb-gw 3GPP compliant by switching from the old SUA code to the new universal SCCP user API with support for (currently) M3UA and SUA. Main changes: Use one cn_link to STP: We will connect to the core network using an (Osmo)STP instance that routes to MSC and SGSN, so we want one SCCP link instead of two. The only difference between IuCS and IuPS is a different remote osmo_sccp_addr. This has various effects through the messaging code; the patch is a bit larger than I would like, but it is hard to separate out truly independent smaller changes. CS or PS domain was previously flagged in the separate cn_link, as ctx pointer for two separate sccp_sap_up()s. Now there's just one such ctx, so determine is_ps from the RANAP Domain Indicator, or from the conn's hnbgw_context_map: - Add is_ps to context_map_alloc_by_hnb(). - To find a matching context, the RUA ID alone is no longer sufficient, also match is_ps (possible optimization todo: separate lists). We would send separate CS or PS Reset messages based on the cn_link, instead send both CS and PS Reset at the same time for the single cn_link. This could be adjusted to detect presence of MSC or SGSN instead. Pending: adjust the VTY config to reflect that there is only one remote address. Place a TODO comment for that. Smaller changes: rua_to_scu(): populate called and calling addresses for N_CONNECT and N_UNITDATA. Remove DSUA. Don't build dummy_cn, which is still implemented on SUA. Mark todo to maybe re-include it based on M3UA later. In hnbgw_cnlink, place sccp related items in a separate sub-struct. Do not keep an llist of cn_links, just have the one. Remove iteration and list management. Change jenkins script to build libosmo-sccp master. Patch-by: hwelte, nhofmeyr Change-Id: I8ac15fa2fd25bedb26297177e416976a5389b573
