freebsd kernel with SKQ

is less than NFS_MINPACKET or greater than NFS_MAXPACKET in size, it barfs and, I think, drops the connection. However, there's no guarantee that in a multi-fragment RPC, all the fragments will be at least as large as NFS_MINPACKET. In fact, with the version of "tclnfs" we have here, which supports NFS over TCP, at least when built under SunOS 4.1.3 (i.e., with 4.1.3's user-mode ONC RPC library), I can *repeatably* cause "tclnfs" to send a request with more than one fragment, one of which is only 8 bytes long. I just do a 3877-byte write to a file, at an offset of 0. The check that "slp->ns_reclen" is greater than or equal to NFS_MINPACKET serves no useful purpose - if the NFS server code can't handle packets < NFS_MINPACKET bytes, it can't handle them over *any* protocol, so the check has to be done above the RPC-over-TCP layer - and should be removed.

This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.12 1998/06/30 08:08:05 jkh Exp $ 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 and the contents of /etc. 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 with config(8) 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. 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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
