PHKL_20228:
( SR: 8606107525 DTS: JAGab77768 )
This patch is one of 8 patches necessary to add support
for the 3 Gb private address space feature.
Defect Description:
PHKL_20228:
( SR: 8606107525 DTS: JAGab77768 )
This is one of 8 patches necessary to add support for the
3 Gb private address space feature. This feature allows a
process to have a private 3rd quadrant (normally the 3rd
quadrant, which is a 1 Gb range of address space from
0x80000000 to 0xC0000000, is used for shared objects). The
chatr command must be used to enable this feature for an
executable (chatr +q3p enable <a.out>). Note that this
feature is only enabled for 32 bit processes running on the
64 bit version of HP-UX.
The other 7 patches necessary to enable this feature are
PHKL_20222, PHKL_20223, PHKL_20224, PHKL_20225, PHKL_20226,
PHKL_20227 and PHKL_20229. Each patch may be installed
independently of the others - if enabling the 3 Gb private
address space feature is not desired. If fewer than all
8 patches are installed, the 3 Gb private address space
feature will not be enabled. The code in this patch that
is part of this feature will not have any impact on the
system until all 8 patches are installed.
Resolution:
A subset of the code to support the 3 Gb private address
space feature was added. When all 8 patches are installed
the following code changes to support this feature will
have been added:
1) Code to recognize the request for a private 3rd
quadrant (Q3) during exec() of an executable.
An executable that requests a private 3rd
quadrant will be referred to as a q3p process
below.
2) Code to prevent allocation of shared objects
in q3p processes.
3) Code to allow data to extend over the 2nd/3rd
quadrant boundary for q3p processes.
4) Code to put the stack for the primary thread
in the 3rd quadrant for q3p processes.
5) Code to map a shared library into the private
address space if there is no more room in the
4th shared quadrant for q3p processes.

------------------------------------------------------------
1. Back up your system before installing a patch.
2. Login as root.
3. Copy the patch to the /tmp directory.
4. Move to the /tmp directory and unshar the patch:
cd /tmp
sh PHKL_20228
5. Run swinstall to install the patch:
swinstall -x autoreboot=true -x patch_match_target=true \
-s /tmp/PHKL_20228.depot
By default swinstall will archive the original software in
/var/adm/sw/save/PHKL_20228. If you do not wish to retain a
copy of the original software, use the patch_save_files option:
swinstall -x autoreboot=true -x patch_match_target=true \
-x patch_save_files=false -s /tmp/PHKL_20228.depot
WARNING: If patch_save_files is false when a patch is installed,
the patch cannot be deinstalled. Please be careful
when using this feature.
For future reference, the contents of the PHKL_20228.text file is
available in the product readme:
swlist -l product -a readme -d @ /tmp/PHKL_20228.depot
To put this patch on a magnetic tape and install from the
tape drive, use the command:
dd if=/tmp/PHKL_20228.depot of=/dev/rmt/0m bs=2k
Special Installation Instructions:
This patch depends on base patch PHKL_18543.
For successful installation please insure that PHKL_18543
is already installed, or that PHKL_18543 is included
in the same depot with this patch and PHKL_18543
is selected for installation.
This patch contains part of the enhancement to enable the
3 Gb private address space feature. It is one of 8 patches.
The other 7 patches necessary to enable this feature are
PHKL_20222, PHKL_20223, PHKL_20224, PHKL_20225, PHKL_20226,
PHKL_20227 and PHKL_20229. Each patch may be installed
independently of the others - if enabling the 3 Gb private
address space feature is not desired. If fewer than all
8 patches are installed, the 3 Gb private address space
feature will not be enabled. The code in this patch that
is part of this feature will not have any impact on the
system until all 8 patches are installed.
In order to be able to use this feature you will need to
reconfigure the kernel with a larger value for the kernel
configurable variable "maxdsiz". In order to do this with
SAM, you will also need to install patch PHKL_20174. Without
PHKL_20174 installed SAM will not allow maxdsiz to exceed
~1.9 Gb. Note that if PHKL_20174 is not installed it is
still possible to manually configure a kernel with a larger
value of maxdsiz (up to 3 Gb) using config(1M).
