Xtables-addons is a package which provides some extra plugins for iptables. It obsoletes the old patch-o-matic repository. Instead of patching the kernel source, extensions are built as modules and thus allow extending kernels without recompilation.

This release fixes a crash in xt_pknock when the chosen hash could not be found as well as taking a wrong code branch. The DNETMAP module now works for kernels older than 2.6.34. Kernels older than 2.6.29 are no longer officially supported.
ipset 5.2 was imported, and the old branch was updated to 4.5. The xt_gradm module has been added, and xt_LOGMARK now prints the remaining lifetime of conntrack entries.
