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 (c009004dfbb12552bcf1d258279f14574fc5b4c1) \ N -- N -- N (9cfe037559bccf5b4652bd449e2b2f1694b8e5f5) 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/openbsc/commit/?id=9cfe037559bccf5b4652bd449e2b2f1694b8e5f5 commit 9cfe037559bccf5b4652bd449e2b2f1694b8e5f5 Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Mon Nov 16 14:52:05 2015 +0100 gtphub: cosmetic: break long lines.

For maintenance, it is convenient to have the log level explicit at each log statement. Tweak some log levels / message formatting while at it.

Allow logging the plane (Ctrl/User) and side (SGSN/GGSN) in functions that only have a gtphub_bind* to work with, by adding a constant label to each bind.

If a GGSN is already known from unmapping, don't invoke a host resolution. In a live working environment, it wouldn't hurt, because the lookups would mostly return from the cache. But in a testing environment without a name server, it barfs on every packet.

Initialize llist_heads to empty (2 were missing). Move those for struct gtphub instances to gtphub_zero() (one moved, one added). In from_[gs]gsns_read_cb(), use a return type that can actually reflect negative return values. resolved_addr.buf: no need to take the address of a byte array var (cosmetic). Pass the proper user data address to sgsn_ares_query(), not the address of the pointer holding the user data address. Initialize ggsn_lookup->expiry_entry (was missing). Publish the function for that in gtphub.h so gtphub_ext.c can use it.

Looking for a segfault, I added a lot of logging. This may be useful for live testing ares, leaving it in there for now. Note: I still want to clean up the logging concerning log levels etc. once we're out of alpha.

Allow a peer sending from an unknown port but a known address, and just create the port (and unmap the seq nr back to this port later to return the response to the sender). Only an SGSN on the Ctrl plane is allowed to make the very first contact from an unknown address.

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, expected to fail (nonstandard port case). In gtphub_test.c, tweak logging so that it is easily visible which test produced which output. Also add the global resolved_sgsn_addr and ggsn_sender, symmetrically to resolved_ggsn_add and sgsn_sender.

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.

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.

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... ;) Sponsored-by: On-Waves ehi http://cgit.osmocom.org/openbsc/commit/?id=c8a614d2e9c56fe13c22f239be82f2a2c958e039 commit c8a614d2e9c56fe13c22f239be82f2a2c958e039 Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Thu Sep 24 17:32:30 2015 +0200 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.)
