2017-09-05ggsn: Add ability to specify local IP addresses for GTP-C and GTP-Ulaforge/osmo-ggsnHarald Welte3-4/+50
In case the GGSN is behind some kind of DNAT, the public GTP-C and GTP-U IP addresses as exposed inside the GTP payload information elements are different from the (internal, behind-nat) IP address to which it listens/binds. Change-Id: I548c9011c9abd66d46f963b1def61575f3dabb89

2017-09-05Rename OpenGGSN to OsmoGGSNHarald Welte34-157/+171
Osmocom has maintained this program since about 7 years now, while the original author / copyright holder has completely disappeared. With the introduction of Osmocom-style CTRL and VTY interfaces, the way how the program is used and configured has substantially changed. In order to avoid confusion in terms of configuration file format etc, let's rename it to OsmoGGSN. Change-Id: I2da30f7d4828e185bfac1a4e2d8414b01cbe4f9d

2017-09-05Remove __sun__ code that is unmaintainedHarald Welte2-264/+0
We haven nobody maintaining this platform, let's remove it. In fact, only Linux and FreeBSD are part of the jenkins build tests, so even Apple/MacOS is up for disposal. However, as it's more popular, let's keep the code. Change-Id: Id6b8179259bacade52c39f96e688f828eff164ac
2017-09-05libgtp: Add back-reference to gsn from pdp contextHarald Welte2-1/+11
This is required once one wants to support multiple GSNs in a single application. WARNING: This breaks ABI compatibility, LIBVERSION must be adjusted Change-Id: I68ae49a765828fa681054c68bf7f5e74dbe48ad2
2017-09-05libgtp: Remove ctrl_handle from gsn_t, replace with private contextHarald Welte1-3/+1
The control interface handle never belonged into libgtp in the first place. Commit 727417dd28813c697b4820aef9f54f249e30c4b8 should not have added this to the shared library (used by sgsnemu, osmo-sgsn, ...), but to some private state of the GGSN. Introducing a private context pointer at the same location will keep ABI compatibilty. Change-Id: I4f17516dae3e04114564828a3e5f6e2ea54212a5

2017-08-30ggsn: Fix DNS not sent in PDP context responsePau Espin Pedrol1-2/+2
During IPv6 support implementation, helper function pco_contains_proto was added which contains an error: It is only capable of finding first protocol correctly, and as a consequence, in my setup DNS servers where not sent back to the SGSN/MS, resulting in phone being able to connect to IPs but not to domain names which required DNS resolution. The condition in the while loop is also changed to match the increment of the variable inside the loop to make it easier to understand at first glance.

2017-08-14update debian/changelog to 0.94 + fix pkg-config versionHarald Welte2-2/+13
This updates the debian changelog to 0.94 and adds some logic to debian/rulres which fixes the version of the libgtp.pc file built as part of our OBS builds (used to be UNKNOWN since commit 23eea1d132120198745dcca32728906d5f05dc5f) Change-Id: I883feaef35ff5ffd1b22fb255b7c36112b4a8f3b
2017-08-13libgtp: Delete PDP context on receiving GTPv1 Error IndicationHarald Welte3-6/+53
When a peer GSN receives a GPDU for an unknown PDP context, it sends a GTP Error Indication. This Error Indication should be used to delete the offending PDP context locally. In GTPv1, the Error Indication contains some mandatory IEs using which we can look up the PDP context and delete it. The existing code only dealt with GTPv0 Error Indications which lack those IEs and use the TEI in the header instead. Change-Id: I3e843f9ef1d6fd7868cc992e083c0891d16b6da9 Closes: OS#2426

2017-08-12Properly format IMSI before using it in trapHarald Welte3-1/+30
For some reason Max' commits introducing the CTRL/trap interface about one year ago didn't convert the IMSI to its actual textual representation before usign it in the CTRL interface. Let's clean that up by properly interpreting the IMSI. Change-Id: I8b20d2e47a29de266d93a7ddd5e6877f7e346a63

2017-08-11Support setting TUN device IPv6 address + prefixHarald Welte3-19/+127
As we can now have PDP contexts with IPv6 user IP payload, it is useful to extend the TUN related code to be able to configure the tun device IPv6 address + prefix length Change-Id: I899d21e52d02e0b8384af29ddd489ff19c8f2cf6
2017-08-11IPv6: in46_addr: OSMO_ASSERT() in case of unsupported callsHarald Welte1-0/+6
There's a bit of trickery with the ip_pool and it's "lengty=8" IPv6 prefix handling, let's make sure we don't accidentially call any support functions with addresses of wrong length. Change-Id: I444c190bdcd18780344e1f0dad4faf3bcf9da5a5
2017-08-11IPv6: Support PCO for IPv6 DNS addressesHarald Welte1-41/+136
In IPv6, DNS server information is not passed along as IPCP6 like in IPv5 with IPCP. The reason is that IPCP6 (for PPP) doesn't support passing DNS server information. Rather, the relevant RFCs indicate DHCPv6 should be used even over point-to-point links. 3GPP decided to avoid DHCPv6 dependency for stateless autoconfiguration (the only mandatory IPv6 configuration mechanism) and added some new non-PPP-style PCO information elements ("containers") which can among other things inform a MS about IPV6 DNS servers. That same mechanism can also be used to inform the MS about IPv4 DNS servers, so for IPv4 there are now two competing mechanisms: IPCP and the new "native" PCO container. With this patch, we support both for IPv4. Change-Id: I21499afd61def8c925f7838bde76f34d28214b56
2017-08-11IPv6: Implement IPv6 prefix assignment via ICMPv6 router advertisementHarald Welte8-2/+510
The 3GPP specs are quite strange when it comes to how an IPv6 address or rather prefix is assigned to an IPv6 PDP context. The designated method for allocating the IPv6 address via the PDP EUA (End User Address) Information Element in the GTP signalling plane is *not* used to allocate the address/prefix. Instead, the EUA is used to allocate an "interface identifier" to the MS, which it the uses to derive its link-local source address to send a router solicitation. The GGSN subsequently answers witha router advertisement, advertising a single/64 prefix, whihcthe MS then uses to generate it's real IPv6 source address for subsequent communication.

2017-08-09ippool: Extend pool to work with /64 prefixesHarald Welte3-8/+17
In IPv6 GPRS, we actually don't want to allocate an individual v6 address (like in IPv4), but we want to allocate a prefix. The standard prefix lengh is 8 bytes, i.e. a /64 prefix. This patch extends the pool to be able to work with such v6 prefixes. Change-Id: I0cf700b6baf195a2e5fbea000531f801acaaa443
2017-08-09in46_addr: Add new function in46a_prefix_equal()Harald Welte2-0/+18
This function is used to compare an IPv6 address against another, using the smaller of the two prefix lengths. Change-Id: Ic993d8abdc90897cb55276f01ae3b8a5eadf5a0d
2017-08-09ggsn: Send proper errors in create_context_ind()Harald Welte3-11/+20
When we receive PDP context requests for unknown PDP types or if we run out of dynamic addresses, we need to inform the SGSN that PDP context creation failed. Change-Id: Ibf199c1726130d27c8f80230b30ee51101c93b06
2017-08-09IPv6 support for user IPHarald Welte4-4/+74
This patch enables the use of IPv6 PDP contexts. The phone will have to request an IPv6 End-user-Address, and the GGSN will have to be configured for an IPv6 pool. The outer transport-layer IP between SGSN and GGSN must still be IPv4, it is not modified by this patch Change-Id: I22c3bf32a98e5daf99d6eaeac8c9f95cc7574774

2017-08-09ippool: Add IPv6 support to IP pool implementationHarald Welte9-172/+374

2017-08-04Proper fix for "Force Dynamic IP" in Create PDP CTXHarald Welte1-1/+3
An EUA length of *2* octets indicates dynamic IP address, while an EUA length of 0 is invalid. Let's fix this hack (which needs to finally be removed anyway). Change-Id: Ib1b57eb0654327882044d6862d955f4b32aa6bcd
