Various fixes and improvements, including possible crashes/infinite loops
in the following dissectors: ATN-CPDLC (crash), WCP (crash), LLDP (crash),
TNEF (loop), SCSI OSD (loop), and a possible crash in pcapng file parsing.
DLT_* values on various OS. Specifically, fixes things so DLT_LOOP packets are
handled by the correct dissector and displayed as IP rather than raw packets.
Has been in -wip for years, tested by lots of ppl there.
Wireshark is a network capture tool and protocol analyzer, including
decoders for very many common and less-common protocols.
Packet dissectors (here in Wireshark, and in other programs such as tcpdump)
have a long history of security problems (but so do other programs in the
portstree..). In wireshark, these are isolated from the packet capture
code (which must have root privileges) by using a separate program,
dumpcap, to run the capture. It is installed setuid root, with
read/execute access granted only to users in the _wireshark group.
Wireshark itself doesn't need privileges if you only plan to analyse
traces produced by tcpdump.
DO NOT RUN WIRESHARK AS ROOT.
