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 (fc33ea2c41702fa99bc1e9c77d3258b79c7123c3)
\
N -- N -- N (5642b41d9cb24fe5fd4e2136ae08c824c5e9f868)
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.

gtphub: don't try to decode IEs in User plane.
Split decoding return code GTP_RC_PDU in GTP_RC_PDU_C and GTP_RC_PDU_U.
Don't do IEs in GTP_RC_PDU_U.
Add a unit test for User plane data.

gtphub: make test code reusable for future tests.
Generalize to make the PDP ctx message definitions and "sending" of
messages
from SGSN->gtphub->GGSN and back reusable in future tests.
Publish gsn_addr_from_sockaddr() in gtphub.h for use in gtphub_test.c.
Use an osmo_sockaddr for resolved_ggsn_addr, because one is needed for
comparison in probably every future test.
Add LVL2_ASSERT() to print assertion message and return instead of abort,
so that functions can be called from several tests without losing the
info of which test caused it from which line.
Use globals for struct gtphub and time_t now, to reduce nr of args that need to
be passed around when writing tests. Add a default test setup function.

gtphub: fix Echo behavior: respond directly.
Up to now I used the Echo as a test for sequence nr mappings. But Echos
should be handled differently: they are scoped on the link and an Echo
response should be sent right back to the requester.

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... ;)

Add GTP hub initial code base.
First steps towards a new GTP hub. The aim is to mux GTP connections, so that
multiple SGSN <--> GGSN links can pass through a single point. Background:
allow having more than one SGSN, possibly in various remote locations.
The recent addition of OAP to GSUP is related to the same background idea.
(This is a collapsed patch of various changes that do not make sense to review
in chronological order anymore, since a lot of it has thorougly transmorphed
after it was first committed.)
