Chapter 12 229
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.
