[PATCH 00/15] Add GTP hub, in early alpha stage

Here is the part of the branch openbsc:neels/gtphub that I believe may be merged to master at this point. (Holger: please go ahead with the merge, or tell me to do so...) The remaining bit is mostly a unit test netcat'ing to a gtphub instance. To do that properly, gtphub must be configurable. Hence I'm starting to add VTY config, which is not complete yet. Hence that part is still omitted here. Neels Hofmeyr (15): Add GTP hub stub, as simplistic UDP forwarder. gtphub: add to build gtphub: add skeletal gtphub.[hc] gtphub: populate API impl from test prog gtphub: add a todo comment gtphub: add TEI map API. gtphub: add gtphub_test.c (empty) gtphub: add TEI map test gtphub: add GTP header validation gtphub: undup code: memset on a struct. gtphub: tweak logging gtphub: index IEs, decode and log a few. gtphub: split gtp_relay() in r/w funcs gtphub: map sequence numbers SGSNs<->GGSNs gtphub: add signal handler to gtphub_main openbsc/.gitignore | 2 + openbsc/configure.ac | 1 + openbsc/include/openbsc/Makefile.am | 3 +- openbsc/include/openbsc/debug.h | 1 + openbsc/include/openbsc/gtphub.h | 151 ++++++++ openbsc/src/gprs/Makefile.am | 4 + openbsc/src/gprs/gtphub.c | 714 ++++++++++++++++++++++++++++++++++++ openbsc/src/gprs/gtphub_main.c | 256 +++++++++++++ openbsc/tests/Makefile.am | 2 +- openbsc/tests/gtphub/Makefile.am | 15 + openbsc/tests/gtphub/gtphub_test.c | 117 ++++++ openbsc/tests/gtphub/gtphub_test.ok | 1 + openbsc/tests/testsuite.at | 7 + 13 files changed, 1272 insertions(+), 2 deletions(-) create mode 100644 openbsc/include/openbsc/gtphub.h create mode 100644 openbsc/src/gprs/gtphub.c create mode 100644 openbsc/src/gprs/gtphub_main.c create mode 100644 openbsc/tests/gtphub/Makefile.am create mode 100644 openbsc/tests/gtphub/gtphub_test.c create mode 100644 openbsc/tests/gtphub/gtphub_test.ok -- 2.1.4
