NFS Mount Access Control
This change is necessary to conform to de facto industry behavior. The behavior of
access= has been modified to conform to a common behavior. If you are using the
undocumented feature to disallow the NFS mounts, it will now succeed.
NOTE Applications that use undocumented features are not "well behaved."
Tighter Security for NFS Mounts
This change is necessary to improve the security of NFS mounts. Without this change,
when you export a filesystem using the root= option of exportfs, NFS-clients on the
root= option are allowed to mount the NFS file system even when they don't appear on
the rw= list and/or access= list. The new behavior disallows NFS clients from
mounting the file system unless they appear in either a rw= and/or access= list.
Memory Size Increase for Process-Private Memory
This change increases the memory size limit for process-private memory. When the 3rd
quadrant private feature is enabled for a process it can only allocate shared objects in
the 4th quadrant. If the 4th quadrant fills up, the application may fail, where it would
not have failed if the 3rd quadrant was available for allocation of shared objects.
Removal of MAXTID and Change to MAXPID
The change raises the number of processes or threads to 8 million. MAXPID, which is
undocumented, will be changed. An alternate mechanism to dynamically determine the
value of MAXPID is introduced.
Fortran 90 GETARG Intrinsic Function
This change causes the semantics of the "index" argument to the HP supplied F90
intrinsic routine GETARG to be compatible with older HP F77 and other vendor
implementations of this routine. Those affected will have to change and recompile their
source code to use the industry standard indexing scheme.
Software Distributor Bundle Algorithm Change
This change allows you to maintain a depot with multiple versions of a Software
Distributor bundle and automatically get the latest version of the bundle without
specifying a version qualifier. The install process no longer prints an error message when
you do not qualify which version of the bundle is intended to be installed.
Software Distributor Automatic Generation of Depot or root
Layout Version
This change allows you to maintain 10.20 and 11.x depots on an 11.x system. It modifies
the SD commands so they do NOT change the layout version of a depot or root
