vfs_syscalls.c:
Changed rename(2) to follow the letter of the POSIX spec. POSIX requires rename() to have no effect if its args "resolve to the same existing file". I think "file" can only reasonably be read as referring to the inode, although the rationale and "resolve" seem to say that sameness is at the level of (resolved) directory entries. ext2fs_vnops.c, ufs_vnops.c: Replaced code that gave the historical BSD behaviour of removing one link name by checks that this code is now unreachable. This fixes some races. All vnodes needed to be unlocked for the removal, and locking at another level using something like IN_RENAME was not even attempted, so it was possible for rename(x, y) to return with both x and y removed even without any unlink(2) syscalls (one process can remove x using rename(x, y) and another process can remove y using rename(y, x)). Prodded by: alfred MFC after: 8 weeks PR: 42617
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/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.
