stuff: unregister_methods() is horribly broken. The idea, if I'm not mistaken, is that the refcount on a method is decremented, and only when it reaches zero is the method freed. However desc->method is set to NULL unconditionally regardless of the refcount, which means the method pointer is trashed the first time the method is deallocated. The obvious detrimental effect is that memory is leaked. The not so obvious effect is that when you call unregister_method() the second time on the same method, you get a NULL pointer dereference and a panic. Now I can successfully unload network device drivers and the miibus module without crashing the system. *sigh* |

This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ 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 and the contents of /etc. 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 with config(8) 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. 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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
