o Separate the kernel stuff from the Yarrow algorithm. Yarrow is now well contained in one source file and one header. o Replace the Blowfish-based crypto routines with Rijndael-based ones. (Rijndael is the new AES algorithm). The huge improvement in Rijndael's key-agility over Blowfish means that this is an extremely dramatic improvement in speed, and makes a heck of a difference in its (lack of) CPU load. o Clean up the sysctl's. At BDE's prompting, I have gone back to static sysctls. o Bug fixes. The streamlining of the crypto stuff enabled me to find and fix some bugs. DES also found a bug in the reseed routine which is fixed. o Change the way reseeds clear "used" entropy. Previously, only the source(s) that caused a reseed were cleared. Now all sources in the relevant pool(s) are cleared. o Code tidy-up. Mostly to make it (nearly) 80-column compliant.
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 ``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/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 have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/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.
