So far, gtphub worked perfectly by only tracking single TEIs ... for probably most uses. But a Ctrl plane tunnel may have expired despite a still active corresponding User plane tunnel. The User plane would continue to work indefinitely, but if any Ctrl messages followed after more than six hours of Ctrl silence, they would have been dropped due to an expired TEI mapping. We want to - combine expiry of a user TEI with its ctrl TEI. (done in this patch) - upon delete PDP context, remove both user and ctrl TEI mappings. (future) - when a peer indicates a restart counter bump, invalidate its tunnels. (future) To facilitate these, track tunnels, complete with both SGSN's and GGSN's address, original and replaced TEIs, all for both user and ctrl plane, in a single struct. A single expiry entry handles the entire tunnel, instead of previously four separate expiries for each endpoint identifier. Add the concept of a "side", being either GGSN or SGSN. Track the originating side in the gtp_packet_desc. For clarity, explicitly track the received header TEI in header_tei_rx, since set_tei() overwrites header_tei to reflect the packet's replaced header TEI, and the originally received header TEI still needs to be used for matching a Create PDP Context Response up with its Request (and for logging). Adjust the test suite to expect tunnel listing strings instead of TEI mappings, with a bonus of making it a lot easier to grok and including the IP addresses. Note: the current implementation is as slow as can possibly be, iterating all the tunnels all the time. Optimizations are kept for a future commit, on purpose. BTW, the sequence number mapping/unmapping structures remain unchanged.

The expiry queues are already used for resolved GGSN addresses, and will soon enlist tunnel structs. Hence the naming should be more general. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gtphub.h | 43 ++++- openbsc/src/gprs/gtphub.c | 338 ++++++++++++++++++++++++++++++------- openbsc/src/gprs/gtphub_ares.c | 2 +- openbsc/src/gprs/gtphub_vty.c | 158 ++++++++--------- openbsc/tests/gtphub/gtphub_test.c | 73 +++++--- 5 files changed, 434 insertions(+), 180 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
