freebsd kernel with SKQ

256 bytes) caused it to break on many devices. The SCSI spec says that for commands with 8-bit length fields, a value of 0 means 256 bytes. As it turns out, many devices don't deal with that properly. Some interpret the 0 as 0, and return no data. Others return more than 256 bytes of data, and cause an overrun. The fix is to tell the device we've only allocated SHORT_INQUIRY_LENGTH (36 bytes) of inquiry data, instead of sizeof(struct scsi_inquiry_data). camcontrol.c: Change inq_len in the call to scsi_inquiry() to SHORT_INQUIRY_LENGTH, and add a long comment explaining the reason for the change. scsi_all.h: Add a comment above the definitinon of SHORT_INQUIRY_LENGTH alerting people that it is both the initial probe inquiry length, and the minimum amount of data needed for scsi_print_inquiry() to function. scsi_all.c: Add a comment about SHORT_INQUIRY_LENGTH being the minimum amount of data needed for scsi_print_inquiry() to function.

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 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).
