attribute namespace and DAC protection on file: - Attribute names beginning with '$' are in the system namespace - The attribute name "$" is reserved - System namespace attributes may only be read/set by suser() or by kernel (cred == NULL) - Other attribute names are in the application namespace - The attribute name "" is reserved - Application namespace attributes are protected in the manner of the target file permission o Kernel changes - Add ufs_extattr_valid_attrname() to check whether the requested attribute "set" or "enable" is appropriate (i.e., non-reserved) - Modify ufs_extattr_credcheck() to accept target file vnode, not to take inode uid - Modify ufs_extattr_credcheck() to check namespace, then enforce either kernel/suser for system namespace, or vaccess() for application namespace o EA backing file format changes - Remove permission fields from extended attribute backing file header - Bump extended attribute backing file header version to 3 o Update extattrctl.c and extattrctl.8 - Remove now deprecated -r and -w arguments to initattr, as permissions are now implicit - (unrelated) fix error reporting and unlinking during failed initattr to remove duplicate/inaccurate error messages, and to only unlink if the failure wasn't in the backing file open() 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.
