Re: Doubts regarding the GPLv(2,3) compatibility of libpcap

Hello List,

I've some doubts whether it is OK to distribute binaries of GPL programs
linked against libpcap. Being one of the Wireshark (nee Ethereal)
authors that's something I'd like to hear some (hopefully well founded)
opinions on.

While the main license file says it's 3 clause BSD, some of the files
are covered (inside) with a 4 clause bsd license. Some of these files
are covered by the 4-clause license from the University of california,
who waived the 4th clause some years ago but some files contain the
following text:

I think the FSF juge that this license is not compatible. Personally I have difficulties to understand why does it not fall with the points b and c (par 7) of GPLv3

# b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or # c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
