find_node: The reference count needs to be increased while the lock is held. Otherwise, the node may disappear right after the lock was released and increase was attempted, leading to an oops. remove_node: The reference count needs to be checked while the lock is held. Otherwise, the node may be used in the match function or returned from find_node while it has a zero refcount.
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. 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/libxt_foobar.c extensions/libxt_foobar.man extensions/xt_foobar.c extensions/xt_foobar.h
