* Switch kernel to use per-cpu counters for rules. * Keep ABI/API. Kernel changes: * Each rules is now exported as TLV with optional extenable counter block (ip_fW_bcounter for base one) and ip_fw_rule for rule&cmd data. * Counters needs to be explicitly requested by IPFW_CFG_GET_COUNTERS flag. * Separate counters from rules in kernel and clean up ip_fw a bit. * Pack each rule in IPFW_TLV_RULE_ENT tlv to ease parsing. * Introduce versioning in container TLV (may be needed in future). * Fix ipfw_cfg_lheader broken u64 alignment. Userland changes: * Use set_mask from cfg header when requesting config * Fix incorrect read accouting in ipfw_show_config() * Use IPFW_RULE_NOOPT flag instead of playing with _pad * Fix "ipfw -d list": do not print counters for dynamic states * Some small fixes
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
