This allows to separate the servers for the local network and GRX from each other. http://cgit.osmocom.org/openbsc/commit/?id=2118e63692bc335880ed6a011f16eb3a… commit 2118e63692bc335880ed6a011f16eb3a539106ba Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon May 25 12:26:49 2015 +0800 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. http://cgit.osmocom.org/openbsc/commit/?id=66e7106d393368b2dd0d04c08f31781e… commit 66e7106d393368b2dd0d04c08f31781ed997380b Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon May 25 01:21:50 2015 +0800 sgsn: Integrate c-ares with the osmocom event loop c-ares is an asynchronous DNS resolver and we need it to resolve the GGSN address. This is integrating the library into our infrastructure. We will create and maintain a list of registered FDs (c-ares is currently only using one of them) and (re-)schedule the timer after events occurred. http://cgit.osmocom.org/openbsc/commit/?id=ccd2312d10e14747e8a4d26d8f72b052… commit ccd2312d10e14747e8a4d26d8f72b052ffcfc282 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Sun May 24 16:48:22 2015 +0800 sgsn: Create a copy of the msgb for later usage When needing to do an asynchronous DNS query we need to keep the TLV data around. So create a wrapper that takes a copy of it and frees it after the call. I can change the code to add an out parameter to decide if the msgb should be freed or not. Pick network failure in case the msgb could not be cloned in the hope the MS will retry then. http://cgit.osmocom.org/openbsc/commit/?id=7605bdc02c011d9d7f5d24458c65948a… commit 7605bdc02c011d9d7f5d24458c65948ac7bf501a Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Sun May 24 12:42:26 2015 +0800 sgsn: Re-factor the activate PDP code for future changes A real SGSN will dynamically resolve the APN name into the GGSN IP Address. This means that after we have collected all information we need to start to resolve the GGSN and then can continue. http://cgit.osmocom.org/openbsc/commit/?id=08bb84b04e15c97739b9c11b2f26407e… commit 08bb84b04e15c97739b9c11b2f26407ee663bc24 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon May 25 14:35:10 2015 +0800 sgsn: Deal with no static ggsn being configured at all In case no static ggsn is configured the code would crash with the assumption that there is always such a GGSN. http://cgit.osmocom.org/openbsc/commit/?id=9270d99f3db58e70d50ad45644b039b3… commit 9270d99f3db58e70d50ad45644b039b3fa314574 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Sun May 24 20:51:17 2015 +0800 sgsn: If there is a subscr don't allow an empty list This is a left-over from the initial system where no PDP was provided by the system. For now if there is a subscr attached and no PDP context provisioned. He is not allowed to have a data connection. Update the testcase to create the pdp list entry more early with a wildcard and then change it to a specific match. ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
