+ configuration: make sure that the NUL at the end of the config string is properly detected and handled, and the stats passed up via sysctl properly reflect which interfaces do bridging. (The whole config support might make good use of some cleanup in the future). + fixed some bugs related to the corruption of multicast and broadcast packets: make sure that for those packets the entire IP + ethernet header is in the mbuf, not in a cluster, so that writes performed in that area by the upper layers do not affect us. + performance: when calling m_pullup, make room for the ethernet header as well, we are going to add it in right after. Also, change an m_dup back to m_copypacket. The former is not necessary anymore now, and it did not help, anyways. I will do a fast MFC because 95% of this patch is fixing bad bugs and i doubt anyone would test the fix in CURRENT. Plus the last two items mostly bring back some code which was already there in 4.0 times.
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.
