b1bcb62 by Martin Kaiser (wireshark@xxxxxxxxx):
make IPv4 and IPv6 name resolution usable at all times
IPv4 and v6 name resolution are bound to a capture file. Using a lua
script, it is possible to trigger a name resolution when no capture file
is open. This crashes Wireshark as the hash tables for name resolution
are not initialized at this time.
martin@reykholt:~/src/wireshark.git/build$ echo "print(Address.ip(\"1.1.1.1\"))" > bla.lua
martin@reykholt:~/src/wireshark.git/build$ ./run/tshark -Xlua_script:bla.lua
Segmentation fault
martin@reykholt:~/src/wireshark.git/build$ echo "print(Address.ipv6(\"::1\"))" > bla6.lua
martin@reykholt:~/src/wireshark.git/build$ ./run/tshark -Xlua_script:bla6.lua
Segmentation fault
Make sure that the hash tables are available as long as the epan library
is initialized. Add a new function host_name_lookup_reset(), call this
function every time we set up dissection for a new capture file. This
way, we keep the name resolution results separate per capture file.
Reorder the steps in init_dissection(). Host name lookup is now
available at all times, there's no need to be in file scope when it's
initialized.
