Patch Name:  PHKL_1163

Patch Description: Writing to text in xdb can crash system.

   This patch fixes a problem where using xdb to write to the text region of
   a process can cause the system to crash with "Kernel DMEM protection
   fault".  This patch will also keep gdb from crashing HP-UX, although it
   will prevent gdb from suceeding at what it was trying to write so gdb may
   need some more work.  It needs to do a PT_WRTEXT or PT_WIUSER to set
   breakpoints instead of a PT_WDUSER.  This is the best thing to do anyways,
   as HP-UX makes sure the text if private and other nice things if PT_WRTEXT
   or PT_WIUSER is used.

   The file fixed was sys.800/sys_proc.o

---------------------------------------------------------------------------
After getting the patch onto your machine, unshar the patch (sh PHKL_1163).

To install this patch do the following:
1) Run the update program (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: /tmp/PHKL_1163.updt"
   (this assumes that you are in the /tmp directory where PHKL_1163.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".
6) From here on follow the standard directions for update.

The customized script that update runs will move the original software
to /system/PHKL_1163/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHKL_1163.text file to /system/PHKL_1163 to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example the
following will create a copy of the patch that update can read:
dd if=PHKL_1163.updt of=/dev/rmt/0m bs=2048
