2015-12-08gtphub: log: limit length of hex dumps.Neels Hofmeyr2-4/+7
The debug log prints the received/sent bytes in hex. When this data surpasses the buffer size available for the log string (4096), the log is truncated and lacks a newline character. Limit the amount of dumped bytes to 1000. Sponsored-by: On-Waves ehi

2015-12-07gtphub: improve handling of restarted peer.Neels Hofmeyr3-20/+60
Handle peer restart earlier, so that all the tunnels are deleted by the restart code path, instead of the first one being deleted due to reused TEI. That caused confusing logging messages. Also, when receiving Delete confirmations from the peer that didn't restart, don't complain about unknown peer, but acknowledge and remove the half invalidated tunnel. This means that the pending delete entry from the restart code path is not needed / not used, so don't bother to add pending delete entries upon peer restart. The test test_peer_restarted_reusing_tei() hits the situation where a tunnel is removed because of a reused TEI rather than the restart counter. Adjust the test to expect the "out-of-band" delete request earlier on, and to still see the half invalidated tunnel around. Enhance the test by adding the delete response from the peer that didn't restart, and add a final tunnels_are() verification. Sponsored-by: On-Waves ehi

2015-12-07gtphub: simplify/fix: one TEI mapping per tunnel.Neels Hofmeyr4-125/+144
Because the sender is known, one unique TEI per tunnel suffices to map the TEIs that the peers are sending to gtphub, instead of previously 4 (SGSN<->GGSN interaction on User and Ctrl plane, where each had an own unique TEI). Also, previously, a tunnel's endpoints should also have been checked against each other for TEI reuse, not only against the endpoints of other tunnels. This simplification fixes that problem for free. Thus simplify TEI reuse detection and improve VTY show readability and debugging. Adjust log and VTY output for tunnels. Adjust tests accordingly.

2015-12-07gtphub: logging: have one newline per log.Neels Hofmeyr2-18/+12
Some logging was multiline to ease human reading of debug output. However, in the VTY output, these newlines lack a CR motion. Split multiline logs into separate lines. Also add one missing space. Sponsored-by: On-Waves ehi

2015-12-05gsm_data_shared: compute/sprintf the lchan name only onceHarald Welte2-2/+11
We now store the pre-printed lchan name in lchan->name to avoid having to call sprintf every time there is a debug statement somewhere, particularly as most of those debug statements are going to be inactive most of the time.

2015-12-03gtphub: implement sgsn_use_sender for NAT.Neels Hofmeyr3-2/+52
If an SGSN is behind NAT, we cannot rely on the default ports. Specifically, if a GGSN sends a message, the forwarding to the SGSN should go to whichever port the SGSN last sent from (whether sequence nr is known or not). Add sgsn_use_sender config and VTY command, and store the sender instead of the GSN Address IE and default port if set. Sponsored-by: On-Waves ehi
2015-12-03gtphub: prepare: keep tunnel ref in gtp_packet_desc.Neels Hofmeyr1-25/+38
Rather than passing a tunnel pointer as function arguments, keep it in the gtp_packet_desc struct passed around anyway. Reason: in the next commit (will add sgsn_use_sender), I need the tunnel to be passed back out to gtphub_handle_buf(), and besides simplifying existing code, this also makes passing the tunnel back out trivial.

2015-12-03gtphub: handle Delete PDP Context.Neels Hofmeyr4-19/+229
During resolution of the header TEI, also return the tunnel struct that resolved the TEI, so the Delete PDP Ctx code does not need to look it up again. Upon Delete PDP Ctx Request, remember the IEs and that a request was made. Upon Delete PDP Ctx Response, find the pending delete and remove the corresponding tunnel, iff the response indicates success. Add a context deletion to regression tests, rename the test appropriately. Sponsored-by: On-Waves ehi
