work present in FreeBSD 7.0 to refine the kernel privilege model: - Introduce support for jail as a testing variable, in order to confirm that privileges are properly restricted in the jail environment. - Restructure overall testing approach so that privilege and jail conditions are set in the testing infrastructure before tests are invoked, and done so in a custom-created process to isolate the impact of tests from each other in a more consistent way. - Tests now provide setup and cleanup hooks that occur before and after the test runs. - New privilege tests are now present for several audit privileges, several credential management privileges, dmesg buffer reading privilege, and netinet raw socket creation. - Other existing tests are restructured and generally improved as a result of better framework structure and jail as a variable. For exampe, we now test that certain sysctls are writable only outside jail, while others are writable within jail. On a similar note, privileges relating to setting UFS file flags are now better exercised, as with the right to chmod and utimes files. Approved by: re (bmah) Obtained from: TrustedBSD Project
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.
