93b99d6264 In TTEST2(), check to make sure the "l" argument isn't so large that 
"snapend - l" underflows; this fixes a buffer overflow with malformed
NFS packets, and may fix other buffer overflows with malformed packets.

7524a0790d * Buffer-safe string function cleanup. There are a couple of strcpy() 
and strcat()s which would be more difficult to fix, but I think they're
  safe anyway.
* Don't crash at runtime by overflowing a buffer with constant data in
  print-icmp.c on a long hostname.
* Don't overflow a static buffer by trying to decode an AFS ACL into a buffer
  which is way too small for it.

722012cc0c World, I'd like you to meet the first FreeBSD token Ring driver. 
This  is for various Olicom cards. An IBM driver is following.
This patch also adds support to tcpdump to decode packets on tokenring.
Congratulations to the proud father.. (below)

0bfc6e6706 This is a hack. Decode IEEE 802.1Q VLAN tagging so that we can decode 
tagged traffic according to the encapsulated protocol.  It needs in
addition modifications to the filter generator which would deal with
checking the ethertype and vlan header as required.

2ebf6c0513 Merge tcpdump 3.3. 
The print_nfs.c changes are pretty extensive; this is partially because
 LBL did a lot of cleanup and partially because I removed lots of
 pointless changes away from the LBL style.

eb1accc762 LBL chose to use IPPROTO_ENCAP to represent IP proto 4 encapsulation 
as performed by the multicast kernel modifications.  However, BSD
already had IPPROTO_ENCAP defined as 98 (RFC 1241 encapsulation).

This changes the use of IPPROTO_ENCAP to IPPROTO_IPIP, which is
the BSD name for IP proto 4.
