freebsd kernel with SKQ

Syslogd should ensure that f_file is a valid file descriptor when f_type is FILE, CONSOLE, TTY and for a PIPE where f_pid > 0. If the descriptor is closed/invalid then the type should be set to UNUSED or the pid should be set to 0. To this end: 1) Don't close(f->f_file) if we can't send a message to a remote host because the file descriptor used for remote logging is stored in finet, not in f->f_file. f->f_file is probably uninitialised, so I guess we usually end up closing fd 0. 2) Don't close PIPE file descriptors if they are invalid. 3) If the call to p_open fails, don't set the pid. The OpenBSD patches in this area set f_file to -1 after the fd is closed and then avoids calling close if f_file < 0. I haven't done this, but it might be a good idea too.

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.
