2017-11-20osmo-hnbgw: drop erratic log line on remote STP addressNeels Hofmeyr1-2/+0
The stp_host is just the *default* that may be overridden by the VTY configuration. Don't log it as the one that is going to be used. It's not trivial to print the actual IP address being used, there may be any number of ASP, theoretically. Hence leave logging up to osmo_sccp_simple_client_on_ss7_id(), after another hypothetical patch. Change-Id: Ia438143606913faccc8cdf4fd5f7d376f93e7891

2017-10-04Makefile.am: Link libosmo-ranap against libosmo-sigtranHarald Welte1-1/+2
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. Below example is from building using contrib/jenkins.sh on Ubuntu 17.04: CCLD test-ranap ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_sccp_local_addr_by_instance' ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_sccp_tx_unitdata_msg' ../../src/.libs/libosmo-ranap.so: undefined reference to `vty_out' ../../src/.libs/libosmo-ranap.so: undefined reference to `install_element' ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_sccp_user_bind' ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_sccp_user_sap_down' ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_scu_prim_name' ../../src/.libs/libosmo-ranap.so: undefined reference to `osmo_sccp_addr_dump' collect2: error: ld returned 1 exit status Makefile:418: recipe for target 'test-ranap' failed Change-Id: Ibfbcafd31c91dc630d406ec39b3b076bdb1f4c19

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().

2017-08-09make point codes configurable by SCCP address bookNeels Hofmeyr4-88/+111
In the vty config, use the SCCP address book to configure the local and remote SCCP addresses. Add VTY commands to set the remote SCCP addresses by name, derive the ss7 instance from these addresses: cs7 instance 1 point-code 0.23.0 sccp-address msc point-code 0.0.1 sccp-address sgsn point-code 0.0.2 hnbgw iucs remote-addr msc iups remote-addr sgsn Enforce that both IuCS and IuPS use the same ss7 instance. In the future, we may add the feature to use two separate instances.

2017-07-31move openbsc.git's iu.h, iu.c, iu_vty.c here as iu_clientNeels Hofmeyr3-1/+924
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.

When receiving unitdata from the CN, verify that it is indeed coming from the remote address that matches our CS/PS domain settings. This patch came from an earlier stage where the is_ps out-parameter was actually used. While it currently isn't, it doesn't hurt to leave it there.

With a headroom of 256, the SGSN crashes with: msgb(0x6e3b90): Not enough headroom msgb_push (256 < 264) I'm not perfectly sure what amount of headroom is strictly necessary. The only reason to pick 512 is that it is twice the amount of 256. Change-Id: I9a193846902a0477af0873f78283c4f2bedaf5dd

2017-07-05migrate osmo-hnbgw to libosmo-sigtran's SCCP/M3UANeels Hofmeyr6-120/+114
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

The guaranteedBitrate lowers from 12200 to 6700, which is mimicking the values found in a trace from a production 3G environment. So far we have no reason to choose these values other than knowing that other operators seem to do this. This came up while trying to fix voice RAB for the nano3G, but this patch had no effect on that. Now that it's here, we might as well keep it. Change-Id: Ia7eecca43d62a6a020466e9b8dc8b566ca988f9f
2017-02-02ranap: make X.213 NSAP 160 bits long, zero paddedNeels Hofmeyr2-12/+16
For IPv4 addresses, only 56bit of X.213 NSAP are used. The sysmocell5000 accepts such a field that is 56bits long, but the ip.access nano3G does not (and crashes instead). Both work when zero-padded to 160bits size. So far we used to send the IPv4 address as "raw" 32bits to the nano3G to avoid the crash. With this zero padding we no longer need such a workaround and can use identical config for both cells. Change-Id: I070bbfe887ab93d08322df30571050a381d082d5

2016-09-27hnbap: accept UE Register Requests with TMSI and pTMSINeels Hofmeyr2-4/+129
Add the option to allow UE Register Requests with a TMSI identity. Add VTY command to enable this option, 'hnbap-allow-tmsi'. Add hnbgw_tx_ue_register_acc_tmsi(). HNBGW so far keeps track of UEs that have registered, with their IMSI. When a UE registers with only a TMSI, we obviously can't store an IMSI. However, since we're so far never *using* the list of UEs in osmo-hnbgw, we might as well just accept the TMSI registration and carry on as usual. All that is needed for proper operation is a valid UE context. This is aimed at the ip.access nano3G femto cell, as it apparently feeds whichever identification the UE sends through to HNBAP (TMSI+LAI, pTMSI+RAI), instead of an IMSI as expected. So far this caused failures and the need to make the UE clear its TMSI (wait several minutes or attempt to subscribe to a different network), so that UE registration switched back to IMSI. When simply accepting the TMSI in osmo-hngw, no problems are apparent in our current code state. For example, a Samsung Galaxy S4 seems to send a UE_Identity_PR_tMSILAI (CS identity), and a GT-I9100 seems to send a UE_Identity_PR_pTMSIRAI (PS identity) upon first registration to the network. Recording the IMSI in hnbgw: we could use the subscriber list during paging, to page a UE on only its last seen HNB. On the other hand, it doesn't hurt to anyway always page to all HNBs connected to osmo-hnbgw. The paging procedure does include a page-to-all-HNBs in case the first HNB paging fails. But we must be aware that UEs that register by TMSI will simply not have an IMSI recorded in the list of UE contexts, so a lookup based on IMSI may fail.

The easy alternative might be to add -I$(top_srcdir)/src to src/Makefile.am. Remove -I$(top_srcdir)/src from src/tests/Makefile.am, no longer needed.
