That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (02058a0ee72f0d2a226f976957f28d7e2dce614d) \ N -- N -- N (69ba8a611a6e4bf5e92cb84d56f147732e9b2d89) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openggsn/commit/?id=69ba8a611a6e4bf5e92cb84d56f147732e9b2d89 commit 69ba8a611a6e4bf5e92cb84d56f147732e9b2d89 Author: Harald Welte <lafo...@gnumonks.org> Date: Thu Aug 3 00:47:03 2017 +0200 Support setting TUN device IPv6 address + prefix 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 http://cgit.osmocom.org/openggsn/commit/?id=c2897ac13f6b289e74c001a5cad6b068bf2ca1df commit c2897ac13f6b289e74c001a5cad6b068bf2ca1df Author: Harald Welte <lafo...@gnumonks.org> Date: Wed Aug 9 21:58:12 2017 +0200 IPv6: in46_addr: OSMO_ASSERT() in case of unsupported calls 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.

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.

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.

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.
