netsniff-ng: Exit gracefully for all possible termination signals
Handle all termination signals that we're allowed to handle (SIGKILL can't be handled) in order to exit gracefully in any regular termination case. Without this fix, pcap files written by netsniff-ng might be corrupted. Reported-by: Mike Westmacott <mikewestmacott@googlemail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

t only one offload device exists. But for FIB notifier, we assume multiple offload devices. So the patch introduces a per FIB entry reference counter and helpers use it in order to achieve this: 0 means RTNH_F_OFFLOAD is not set, no device offloads this entry n means RTNH_F_OFFLOAD is set and the entry is offloaded by n devices Patches 3 and 4 convert mlxsw and rocker to adopt this new way, registering one notifier block for each asic instance. Both of these patches also implement internal "abort" mechanism. Using switchdev ops, "abort" is called by switchdev core whenever there is an error during FIB entry add offload. This leads to removal of all offloaded entries on system by fib_trie code. Now the new notifier assumes the driver takes care of the abort action. Here's why: 1) The fact that one HW cannot offload an entry does not mean that the others can't do it. So let only one entity to abort and leave the rest to work happily. 2) The driver knows what to in order to properly abort. For example, currently abort is broken for mlxsw, as for Spectrum there is a need to set 0.0.0.0/0 trap in RALUE register. The fifth patch removes the old, no longer used FIB offload infrastructure. The last patch reflects the changes into switchdev documentation file. --- v2->v3: -patch 3/6 -fixed offload inc/dec to be done in fib4_entry_init/fini and only in case !trap as suggested by Ido v1->v2: -patch 3/6: -fixed lpm tree setup and binding for abort and pointed out by Ido -do nexthop checks as suggested by Ido -fix use after free during abort -patch 6/6: -fixed texts as suggested by Ido ==================== Signed-off-by: David S.
