- Restore the ability to look up network names in the networks(5) database by passing getnetbyaddr(3) shifted network numbers, but without duplicating the old bug that was fixed in 1.27 (we now only shift netnums with standard netmasks). For example: Before: $ netstat -r [...] 127.0.1/24 localhost UGSc 0 0 lo0 127.0.2/24 localhost UGSc 0 0 lo0 After: $ netstat -r [...] subnet1/24 localhost UGSc 0 0 lo0 subnet2/24 localhost UGSc 0 0 lo0 - Only try to lookup with the forged netmask if the mask was not explicitly specified, like it was before 1.27. For example: Before: $ netstat -r net-44.ampr.org/25 localhost UGSc 0 0 lo0 net-44.ampr.org/25 localhost UGSc 0 0 lo0 After: 44.108.2/25 localhost UGSc 0 0 lo0 44.108.2.128/25 localhost UGSc 0 0 lo0 - Make sure to null-terminate the resulting string. MFC after: 1 week
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.
