socket support. These utility routines are used only for routing and pfkey sockets, neither of which have a notion of address, so were required to mock up fake socket addresses to avoid connection requirements for applications that did not specify their own fake addresses (most of them). Quite a bit of the removed code is #ifdef notdef, since raw sockets don't support bind() or connect() in practice. Removing this simplifies the raw socket implementation, and removes two (commented out) uses of dtom(9). Fake addresses passed to sendto(2) by applications are ignored for compatibility reasons, but this is now done in a more consistent way (and with a comment). Possibly, EINVAL could be returned here in the future if it is determined that no applications depend on the semantic inconsistency of specifying a destination address for a protocol without address support, but this will require some amount of careful surveying. NB: This does not affect netinet, netinet6, or other wire protocol raw sockets, which provide their own independent infrastructure with control block address support specific to the protocol.

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.
