[gprs] Build the SGSN stand-alone and not as part of bsc_hack Instead of continuing to add more and more functionality to the bsc_hack binary, we should have the new SGSN code run as a separate executable. After this commit we now build a 'osmo_sgsn' executable, using its own osmo_sgsn.cfg config file. However, the SGSN is not yet functional, mainly due to the fact that the BSSGP and GMM code are written with the assumption that there is a msgb->trx->bts and the according 'sturct gsm_bts' data model around - which clearly is no longer the case outside of bsc_hack.

sgsn: Add VTY configuration for the CDR module Make it possible to set a filename to use for the CDR. By default no CDR will be generated. Forbid to set the interval of 0 seconds as this will cause a lot of work. Add a very basic VTY test.

sgsn: Add VTY commands to manage subscriber cache This adds the following commands to the ENABLE node: - show subscriber cache - update-subscriber imsi IMSI insert authorized (0|1) - update-subscriber imsi IMSI cancel - update-subscriber imsi IMSI commit These commands are mainly testing tools and maintenance helpers. The update commands work asynchronously and can be used to complete a pending update request or to terminate an existing connection. The 'insert' command just update the subscriber records but does not notify the GMM layer. Invoke the 'commit' command to continue with pending procedures. Note that the subscriber cache is not stored persistently and will always be empty after an SGSN restart. Sponsored-by: On-Waves ehf

sgsn: Integrate subscriber handling into the SGSN This commit adds a new authorization policy 'remote' and uses the subscriber cache for authorization when this policy is being used. Note that there is no remote backend implemented yet. After the IMSI/IMEI have been acquired, a request would be sent to the remote peer. The attach/auth-ciph procedure continues when authorization info has been received from the peer. This means, that gprs_subscr_update() must be called then to tell the GMM layer that it can proceed. A later commit will add VTY commands to do this manually. Sponsored-by: On-Waves ehf

gtphub: add first bits of GRX ares For the resolving function, change the function signature to return a gtphub_peer_port. In consequence, publish two functions concerned with gtphub_peer_port instances for use in test and gtphub_ext.c. Add GGSN resolution queue, callback and cache. Simple implementation: if an SGSN asks for a GGSN, it will first get no answer, and I hope it will ask again once the GGSN is in the cache. Within gtphub_ext.c, have a dummy sgsn struct, as the sgsn_ares code currently depends on it (half the functions pass an sgsn instance pointer around, but the other half use the global one). In the unit tests, wrap away the ares initialization so that they can work without a DNS server around. The netcat test breaks because of this, will remove it. Using sgsn_ares, implement the gtphub_resolve_ggsn_addr() function, I hope: untested. Minor cosmetics just to see if you're paying attention... ;) Sponsored-by: On-Waves ehi

[gprs] Build the SGSN stand-alone and not as part of bsc_hack Instead of continuing to add more and more functionality to the bsc_hack binary, we should have the new SGSN code run as a separate executable. After this commit we now build a 'osmo_sgsn' executable, using its own osmo_sgsn.cfg config file. However, the SGSN is not yet functional, mainly due to the fact that the BSSGP and GMM code are written with the assumption that there is a msgb->trx->bts and the according 'sturct gsm_bts' data model around - which clearly is no longer the case outside of bsc_hack.

VTY: improve VTY prompt and make sure exit/end works everywhere Some nodes below 'config' didn't have ournode_exit / ournode_end, and thus were not able to properly perform this function. exit should always only go back one level, while end drops us back to ENABLE_NODE. The prompt now represents the nesting level, and there's one consistent space after the final prompt character (typically #).

The following VTY commands are added to 'config-sgsn': - apn APN ggsn <0-255> - apn APN imsi-prefix PREFIX ggsn <0-255> which maps an APN gateway string to an SGSN id. The SGSN must be configured in advance. When matching an APN string, entries with a leading '*' are used for suffix matching, otherwise an exact match is done. When a prefix is given, it is matched against the IMSI. If several entries match, a longer matching IMSI prefix has precedence.

sgsn: Allow to resolve the IPv4 address of a GGSN through DNS For real networks we need to check if the requested APN string is allowed and then resolve the GGSN address through DNS. There are countries with two or three digit MNCs and one could either try to keep a list of countries that have two/three digits or just try both of them. I have opted for the later for the ease of the implementation. C-Ares doesn't allow to cancel a request so we will need to have the MMCTX and the Lookup have different lifetimes. We simply set ->mmctx to NULL in case the MMCTX dies more early. The selected and verified apn_str will be copied into the out parameter. In case no static APN/GGSN config is present and the dynamic mode is enabled a request will be made.

sgsn: Delete PDP contexts properly Currently the PDP contexts are hard freed (via sgsn_pdp_ctx_free) at some places in gprs_gmm.c on the reception of a Detach Req and on re-use of an IMSI that is already associated with an MM context. This can lead to segfaults when there is a pending request or a data indication at libgtp. This patch add a new function sgsn_pdp_ctx_terminate that de-associates the PTP context from the MM context, deactivates SNDCP, sets pdp->mm to NULL and then calls sgsn_delete_pdp_ctx. sgsn_libgtp is updated to check for pdp->mm being non-NULL before dereferencing it. The sgsn_pdp_ctx_terminate function will be called for each PDP context of an MM context before this context is going to be deleted via sgsn_mm_ctx_free. To ensure, that the ctx->llme (which is accessed during the deactivation of SNDCP) remains valid, the call to gprs_llgmm_assign is moved after the call to sgsn_mm_ctx_free. The handling of re-used IMSIs is changed to mimic the processing of a Detach Req.

sgsn: Integrate subscriber handling into the SGSN This commit adds a new authorization policy 'remote' and uses the subscriber cache for authorization when this policy is being used. Note that there is no remote backend implemented yet. After the IMSI/IMEI have been acquired, a request would be sent to the remote peer. The attach/auth-ciph procedure continues when authorization info has been received from the peer. This means, that gprs_subscr_update() must be called then to tell the GMM layer that it can proceed.

gprs: Use PURGE MS messages When a subscriber entry is going to be deleted by SGSN and when the subscriber info has been obtained from a remote peer via GSUP, the peer should be informed before the entry is really deleted. For this purpose, MAP defines the PURGE MS procedure (see GSM 09.02, 19.1.4). This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received. Note that GSM 09.02, 19.1.4.4 implies that the subscriber data is not to be removed when the procedure fails which is not the way the feature has been implemented.

If a usre of the code needs key_seq, they need to manage it themselves.

gprs: Do not put the subscr in gprs_subscr_delete Currently gprs_subscr_delete implicitely calls subscr_put, which makes the code more complex than necessary (additional subscr_get) in a few places. It also makes it more difficult to see, whether get/put are balanced within a function. In addition, the functions are not named consistently (gprs_subscr_delete vs. gprs_subscr_put_and_cancel). This commit changes the semantics of gprs_subscr_delete and indirectly of gprs_subscr_put_and_cancel to not call subscr_put on their argument, but to leave that for the caller to do it explicitely.

[gprs] Build the SGSN stand-alone and not as part of bsc_hack Instead of continuing to add more and more functionality to the bsc_hack binary, we should have the new SGSN code run as a separate executable. After this commit we now build a 'osmo_sgsn' executable, using its own osmo_sgsn.cfg config file. However, the SGSN is not yet functional, mainly due to the fact that the BSSGP and GMM code are written with the assumption that there is a msgb->trx->bts and the according 'sturct gsm_bts' data model around - which clearly is no longer the case outside of bsc_hack.

The update commands work asynchronously and can be used to complete a pending update request or to terminate an existing connection. The 'insert' command just update the subscriber records but does not notify the GMM layer. Invoke the 'commit' command to continue with pending procedures. Note that the subscriber cache is not stored persistently and will always be empty after an SGSN restart. Sponsored-by: On-Waves ehf

The update commands work asynchronously and can be used to complete a pending update request or to terminate an existing connection. The 'insert' command just update the subscriber records but does not notify the GMM layer. Invoke the 'commit' command to continue with pending procedures. Note that the subscriber cache is not stored persistently and will always be empty after an SGSN restart. Sponsored-by: On-Waves ehf

sgsn: Add a subscriber based authentication phase This implements the MAP way of subscriber validation when the MS tries to perform an Attach Request: 1. perform authentication (optionally invoke the sendAuthInfo procedure), starts the Auth & Ciph procedure 2. perform update location 3. insert subscriber data 4. finish the update location 5. Attach Accept / Attach Reject The authentication triplets are used and eventually updated if all of them have been used. This is currently accessible via the VTY interface by the following commands: - update-subscriber imsi IMSI update-auth-info - update-subscriber imsi IMSI update-location-result (ok|ERR-CAUSE) Sponsored-by: On-Waves ehf

sgsn: Add functions to handle APN contexts This commit adds the exported functions apn_ctx_find_alloc, apn_ctx_free, apn_ctx_by_name, and apn_ctx_match to manage and retrieve APN to GGSN mappings. The following VTY commands are added to 'config-sgsn': - apn APN ggsn <0-255> - apn APN imsi-prefix PREFIX ggsn <0-255> which maps an APN gateway string to an SGSN id. The SGSN must be configured in advance. When matching an APN string, entries with a leading '*' are used for suffix matching, otherwise an exact match is done. When a prefix is given, it is matched against the IMSI. If several entries match, a longer matching IMSI prefix has precedence. If there are several matching entries with the same PREFIX, the entry with longest matching APN is returned. Ticket: OW#1334 Sponsored-by: On-Waves ehf

sgsn: Allow to resolve the IPv4 address of a GGSN through DNS For real networks we need to check if the requested APN string is allowed and then resolve the GGSN address through DNS. There are countries with two or three digit MNCs and one could either try to keep a list of countries that have two/three digits or just try both of them. I have opted for the later for the ease of the implementation. C-Ares doesn't allow to cancel a request so we will need to have the MMCTX and the Lookup have different lifetimes. We simply set ->mmctx to NULL in case the MMCTX dies more early. The selected and verified apn_str will be copied into the out parameter. In case no static APN/GGSN config is present and the dynamic mode is enabled a request will be made.

VTY: decouple telnet_interface from 'struct gsmnet' We want the VTY and telnet code to be independent from the BSC application(s). As a side note, we also like to eliminate static global variables for 'struct gsm_network' all over the code. As such, telnet_init() is now passed along a "private" pointer, which getst stored in telnet_connection.priv. This telnet_connection is then stored in vty->priv, which in turn gets dereferenced if anyone needs a reference to 'struct gsm_network' from the BSC vty code. Also: * vty_init() now calls cmd_init() * the ugliness that telnet_init() calls back into the application by means of bsc_vty_init() function has been removed. * telnet_init() now returns any errors, so the main program can exit e.g. if the port is already in use.

SGSN VTY: make missing GSUP server address+port fatal On 'auth-policy remote', the SGSN requires GSUP server address and port. If it was missing, the SGSN would print a VTY warning and run anyway. Make this error more fatal: print an error (flattened a bit) to stderr and abort the program. Move validation of the GSUP server data presence out of the VTY command itself and into the config reading function. This way the GSUP server config can be given anywhere, including below the auth-policy config (was required above). Don't care about setting the auth-policy to remote with a telnet VTY, because in that case the GSUP client won't be started anyway. Change-Id: I4d8db910c32abd8579d3c9b9f0b2cb3a9a6dfe4c
