gitosis at osmocom.org gitosis at osmocom.orgThis 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 discards 989873f7bd632c371d1f114881794eb1345dcad2 (commit) discards c3dc638f6b02a4325046ce651628d607670a4424 (commit) via 224672f8ba6cc3396dfe2a02a0faa692025f19c6 (commit) via 0aa62ee3767ce6d9a7d9fb4a0fcea31d582533ac (commit) via cdca81c508b2d6c1f61aa91c5cf7ab8541c23127 (commit) via 32ff8aeff0fc33be8646e3a3b82f1948e6e89644 (commit) via 9270dc8ca347e775f25272aa2cd904e53c93de29 (commit) via 4316cb2f25a583ed759d6823ce9a1b7650e178a9 (commit) 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 (989873f7bd632c371d1f114881794eb1345dcad2) \ N -- N -- N (224672f8ba6cc3396dfe2a02a0faa692025f19c6) 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=224672f8ba6cc3396dfe2a02a0faa692025f19c6 commit 224672f8ba6cc3396dfe2a02a0faa692025f19c6 Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Sun Nov 8 23:39:57 2015 +0100 gtphub: lose the netcat test. http://cgit.osmocom.org/openbsc/commit/?id=0aa62ee3767ce6d9a7d9fb4a0fcea31d582533ac commit 0aa62ee3767ce6d9a7d9fb4a0fcea31d582533ac Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Sun Nov 8 20:34:47 2015 +0100 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... ;) http://cgit.osmocom.org/openbsc/commit/?id=cdca81c508b2d6c1f61aa91c5cf7ab8541c23127 commit cdca81c508b2d6c1f61aa91c5cf7ab8541c23127 Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Thu Sep 24 17:32:30 2015 +0200 Add GTP hub (code bomb). 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.) Sponsored-by: On-Waves ehf gtphub: decode IE GSN addr using inet_ntop. gtphub: cosmetic: fix a name. map addresses wip gtphub: fix style: '} else {' 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. gtphub: cosmetic Tweak comment. Rename gtphub_sep.c to gtphub_ext.c (personal preference) and add copyright header. 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_test: cosmetic Rename seq_map_is to nr_map_is. gtphub: pull out current time to unit tests. An obsolete forward definition is dropped along the way. gtphub: publish gtphub_port_find_sa() to enhance test gtphub_test: find the GGSN peer struct and verify seq_map entries and timeouts. Also verify tei_map entries and timeouts. http://cgit.osmocom.org/openbsc/commit/?id=32ff8aeff0fc33be8646e3a3b82f1948e6e89644 commit 32ff8aeff0fc33be8646e3a3b82f1948e6e89644 Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Mon Oct 19 14:37:12 2015 +0200 sgsn_vty.c: fix typo ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gtphub.h | 24 ++++ openbsc/src/gprs/Makefile.am | 6 +- openbsc/src/gprs/gprs_utils.c | 1 + openbsc/src/gprs/gtphub.c | 148 ++++++++++++-------- openbsc/src/gprs/gtphub_ext.c | 174 ++++++++++++++++++++---- openbsc/src/utils/meas_udp2db.c | 1 + openbsc/src/utils/meas_vis.c | 2 + openbsc/tests/gtphub/Makefile.am | 3 +- openbsc/tests/gtphub/gtphub_nc_test.gtphub.conf | 5 - openbsc/tests/gtphub/gtphub_nc_test.ok | 7 - openbsc/tests/gtphub/gtphub_nc_test.sh | 85 ------------ openbsc/tests/gtphub/gtphub_test.c | 122 +++++++++++++---- openbsc/tests/gtphub/gtphub_test.ok | 4 +- openbsc/tests/gtphub/hex2bin.py | 13 -- openbsc/tests/testsuite.at | 5 - 15 files changed, 371 insertions(+), 229 deletions(-) delete mode 100644 openbsc/tests/gtphub/gtphub_nc_test.gtphub.conf delete mode 100644 openbsc/tests/gtphub/gtphub_nc_test.ok delete mode 100755 openbsc/tests/gtphub/gtphub_nc_test.sh delete mode 100755 openbsc/tests/gtphub/hex2bin.py hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
