effect, which would cause unnecessary route deletion: * Unfortunately, this has the obnoxious * property of also triggering for insertion /above/ a pre-existing network * route and clones. Sigh. This may be fixed some day. The effect has been even worse, because recent versions of route.c set the parent rtentry for cloned routes from an interface-direct route. For example, suppose that we have an interface "ne0" that has an IPv4 subnet "10.0.0.0/24". Then we may have a cloned route like 10.0.0.1 on the interface, whose parent route is 10.0.0.0/24 (to the interface ne0). Now, when we add the default route (i.e. 0.0.0.0/0), rt_fixchange() will remove the cloned route 10.0.0.1. The (bad) effect also prevents rt_setgate from configuring rt_gwroute, which would not be an intended behavior. As suggested in the comments to rt_fixchange(), we need stricter check in the function, to prevent unintentional route deletion. This fix also solve the "IPV6 panic?" problem in nd6_timer().

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.
