This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)".
The branch, neels/gtphub has been updated

This update added new revisions after undoing existing revisions. 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 (b807849c1e51657de2274c41c8cdbba773eca717)
\
N -- N -- N (d84bb8398ce1a01c43b1d2d3f1edb405c221b967)
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.

Tweak comment.
Rename gtphub_sep.c to gtphub_ext.c (personal preference) and add copyright

Sort some definitions around in gtphub.c.
In gtphub_from_sgsns_handle_buf, move a variable into the scope where it is
used.
Remove a debug peer counter.

gtphub: restructure
Allow multiple addresses per peer.
Allow multiple ports per address.
Don't track ctrl<->user plane peers, allow any number of them.
Have a single TEI map per plane, across all GGSNs and SGSNs. This is not only
simpler, but necessary to establish mappings during a Create PDP Context
Request <-> Response (thanks Holger!) -- during a Create PDP Context Request,
we want to map TEI numbers before sending to the GGSN, but the GGSN has not
announced its final tunnel endpoint addresses yet. We can't find an unused TEI
for a given address if we don't know the address. The solution is to have
globally unique mapped TEIs (per Ctrl / User plane).
Change naming: "port" to "plane". There's now a
gtphub_peer_port, so the "port"
naming for the planes was confusing.
Separate expiry from nr_map. It happened along the way, becoming obsolete again
by the central TEI map, and now the code is there.
Constify.
