The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are
fixed-length strings. AFAICT the only place they're read is in
sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated.
However, the kernel doesn't null-terminate them. A bunch of copy-pasted code
uses strncpy to write them, and doesn't guarantee null-termination. For at
least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".
This change null-terminates those fields everywhere they're set in the
kernel. It also shortens a few strings to ensure they'll fit within the
16-character field.

Overview --------------------- This package contains FreeBSD driver source code for HighPoint RocketRAID controller, include: SAS Controller: RR271x, RR272x, RR274x, RR276x, RR278x. NO WARRANTY THE DRIVER SOURCE CODE HIGHPOINT PROVIDED IS FREE OF CHARGE, AND THERE IS NO WARRANTY FOR THE PROGRAM. THERE ARE NO RESTRICTIONS ON THE USE OF THIS FREE SOURCE CODE. HIGHPOINT DOES NOT PROVIDE ANY TECHNICAL SUPPORT IF THE CODE HAS BEEN CHANGED FROM ORIGINAL SOURCE CODE. LIMITATION OF LIABILITY IN NO EVENT WILL HIGHPOINT BE LIABLE FOR DIRECT, INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OF OR INABILITY TO USE THIS PRODUCT OR DOCUMENTATION, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN PARTICULAR, HIGHPOINT SHALL NOT HAVE LIABILITY FOR ANY HARDWARE, SOFTWARE, OR DATA STORED USED WITH THE PRODUCT, INCLUDING THE COSTS OF REPAIRING, REPLACING, OR RECOVERING SUCH HARDWARE, OR DATA. 2. Rebuild the kernel with HighPoint RocketRAID support ----------------------------------------------- 1) Install kernel source package and building tools. 2) Extract the driver files under the kernel source tree: # cd /usr/src/sys/ # tar xvzf /your/path/to/HPT27xx_FreeBSD_Src_v1.2.7.1_15_06_08.tgz 3) Update the kernel configuration file to include the HighPoint source. Assume the configure file is GENERIC, and new kernel configure file is MYKERNEL: # cd i386/conf (or amd64/conf for AMD64) # cp GENERIC MYKERNEL 4) Edit MYKERNEL, and add the following line under "RAID controllers interfaced to the SCSI subsystem": device "hpt27xx" #HighPoint RocketRAID 5) For i386 system, edit /usr/src/sys/conf/files.i386 and append the lines shown below: hpt27xx_lib.o optional hpt27xx \ dependency "$S/dev/hpt27xx/i386-elf.hpt27xx_lib.o.uu" \ compile-with "uudecode < $S/dev/hpt27xx/i386-elf.hpt27xx_lib.o.uu" \ no-implicit-rule dev/hpt27xx/hpt27xx_os_bsd.c optional hpt27xx dev/hpt27xx/hpt27xx_osm_bsd.c optional hpt27xx dev/hpt27xx/hpt27xx_config.c optional hpt27xx For amd64 system, edit /usr/src/sys/conf/files.amd64 and append the lines shown below: hpt27xx_lib.o optional hpt27xx \ dependency "$S/dev/hpt27xx/amd64-elf.hpt27xx_lib.o.uu" \ compile-with "uudecode < $S/dev/hpt27xx/amd64-elf.hpt27xx_lib.o.uu" \ no-implicit-rule dev/hpt27xx/hpt27xx_os_bsd.c optional hpt27xx dev/hpt27xx/hpt27xx_osm_bsd.c optional hpt27xx dev/hpt27xx/hpt27xx_config.c optional hpt27xx 6) Rebuild and install the kernel: a) for FreeBSD 5.x-i386/6.x-i386/7.x-i386/8.x-i386/9.x-i386/10.x-i386: # cd /usr/src/sys/i386/conf/ # /usr/sbin/config MYKERNEL # cd ../compile/MYKERNEL/ # make depend # make # make install b) for FreeBSD 5.x-amd64/6.x-amd64/7.x-amd64/8.x-amd64/9.x-amd64/10.x-amd64: # cd /usr/src/sys/amd64/conf/ # /usr/sbin/config MYKERNEL # cd ../compile/MYKERNEL/ # make depend # make # make install c) for FreeBSD 4.x: # cd /usr/src/sys/i386/conf/ # /usr/sbin/config MYKERNEL # cd ../../compile/MYKERNEL/ # make depend # make # make install If the driver was previously configured as an auto-loaded module by /boot/defaults/loader.conf, please remove the entry hpt27xx_load="YES" from loader.conf to prevent the driver from being loaded twice. 7) Reboot from the new kernel. 3. Build/Load the driver as a kernel module ------------------------------------------------ 1) Install kernel source package and building tools. 2) Extract the driver files under the kernel source tree: # cd /usr/src/sys/ # tar xvzf /your/path/to/HPT27xx_FreeBSD_Src_v1.2.7.1_15_06_08.tgz 4) Build the driver module: # cd modules/hpt27xx # make 5) Copy the driver module to the kernel module directory For FreeBSD 4.x: # cp hpt27xx.ko /modules/ For FreeBSD 5.x/6.x/7.x/8.x/9.x/10.x: # cp hpt27xx.ko /boot/kernel/ 6) Reboot and load the driver under loader prompt. e.g: BTX loader 1.00 BTX version is 1.01 Console: internal video/keyboard BIOS driver A: is disk0 BIOS driver C: is disk2 BIOS 636kB/74512kB available memory FreeBSD/i386 bootstrap loader, Revision 0.8 (mailto:jkh@narf.osd.bsdi.com, Sat Apr 21 08:46:19 GMT 2001) Loading /boot/defaults/loader.conf /kernel text=0x24f1db data=0x3007ec+0x2062c - Hit [Enter] to boot immediagely, or any other key for command prompt. Booting [kernel] in 9 seconds <-- press SPACE key here Type '?' for a list of commands, 'help' for more detailed help. ok load hpt27xx /modules/hpt27xx.ko text=0xf571 data=0x2c8+0x254 ok boot For FreeBSD 5.x/6.x/7.x/8.x/9.x/10.x, you can select 6 on the boot menu to get a loader prompt. 7) You can add a below line into /boot/defaults/loader.conf to load the driver automatically: hpt27xx_load="YES" Please refer to the installation guide in HighPoint FreeBSD driver release package for more information. ############################################################################# Technical support and service If you have questions about installing or using your HighPoint product, check the user's guide or readme file first, and you will find answers to most of your questions here.
