In TCP --strict mode, forget the peer which sent the wrong knock in a sequence, rather than resetting its status to ST_INIT. This avoids filling up the peer table (which would lead to pknock DoS) in case of a DDoS attack performed by a set of port-scanning malicious hosts.
Xtables-addons ============== Xtables-addons is the proclaimed successor to patch-o-matic(-ng). It contains extensions that were not accepted in the main Xtables package. Xtables-addons is different from patch-o-matic in that you do not have to patch or recompile either kernel or Xtables(iptables). But please see the INSTALL file for the minimum requirements of this package. All code imported from patch-o-matic has been reviewed and all apparent bugs like binary stability across multiarches, missing sanity checks and incorrect endianess handling have been fixed, simplified, and sped up. Inclusion into a kernel tree ============================ External extensions =================== The program "xa-download-more" can be used to download more extensions from 3rd parties into the source tree. The URLs are listed in the "sources" file. If the "sources" file contains an entry like http://foobar.org/xa/ xa-download-more will inspect http://foobar.org/xa/xa-index.txt for files to download. That file may contain foobar.tar.bz2 and xa-download-more will then retrieve and unpack http://foobar.org/xa/foobar.tar.bz2. Files that should be contained in the tarball are an mconfig and Kbuild files to control building the extension, libxt_foobar.c for the userspace extension and xt_foobar.c for the kernel extension. mconfig.foobar extensions/Kbuild.foobar extensions/Mbuild.foobar extensions/libxt_foobar.c extensions/libxt_foobar.man extensions/xt_foobar.c extensions/xt_foobar.h
