and so special-casing was introduced to provide extra procfs privilege to the kmem group. With the advent of non-setgid kmem ps, this code is no longer required, and in fact, can is potentially harmful as it allocates privilege to a gid that is increasingly less meaningful. Knowledge of specific gid's in kernel is also generally bad precedent, as the kernel security policy doesn't distinguish gid's specifically, only uid 0. This commit removes reference to kmem in procfs, both in terms of access control decisions, and the applying of gid kmem to the /proc/*/mem file, simplifying the associated code considerably. Processes are still permitted to access the mem file based on the debugging policy, so ps -e still works fine for normal processes and use. Reviewed by: tmm 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 ``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.
