This package provides the source code for the netfilter-extensions kernel modules. kernel source or headers are required to compile these modules.

the following netfilter extensions derived from netfilter.org's patch-o-matic-ng repository are included:

tarpit
ipv4options
set
u32
the modules in this package should be usable with the unmodified linux kernel and iptables packages included in debian; they do not require extracted linux kernel and iptables source trees as part of the build process.

note that these modules are not included in the upstream linux kernel because they may be buggy or experimental and should be used with caution.
