Subject: falsely claims filter rejects all packages
Date: Mon, 20 Jul 2009 10:33:30 +0200
[Message part 1 (text/plain, inline)]
Package: tcpdump
Version: 4.0.0-3
Severity: minor

# tcpdump -ni wifi icmp6 and '(icmp[icmptype] != icmp-echo)' and '(icmp[icmptype] != icmp-echoreply)'
tcpdump: expression rejects all packets

Since icmp-echo and icmp-echoreply are disjunct and their union
a proper subset of icmp6, the expression does not yield the empty
set.

ICMPv6 is not "ICMP in an IPv6 datagram", it's a different protocol.
Since icmp[] implies icmp even if you're testing for non-equality,
the expression is partly equivalent to 'icmp6 and icmp', which
rejects all packets because it can never be true.

What you meant to use is something like icmp6[icmptype], but that's
not yet implemented in libpcap.  Reassigning accordingly.
