* Add namedobject set-aware api capable of searching/allocation objects by their name/idx. * Switch tables code to use string ids for configuration tasks. * Change locking model: most configuration changes are protected with UH lock, runtime-visible are protected with both locks. * Reduce number of arguments passed to ipfw_table_add/del by using separate structure. * Add internal V_fw_tables_sets tunable (set to 0) to prepare for set-aware tables (requires opcodes/client support) * Implement typed table referencing (and tables are implicitly allocated with all state like radix ptrs on reference) * Add "destroy" ipfw(8) using new IP_FW_DELOBJ opcode Namedobj more detailed: * Blackbox api providing methods to add/del/search/enumerate objects * Statically-sized hashes for names/indexes * Per-set bitmask to indicate free indexes * Separate methods for index alloc/delete/resize Basically, there should not be any user-visible changes except the following: * reducing table_max is not supported * flush & add change table type won't work if table is referenced Sponsored by: Yandex LLC
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.
