Known Compatibility Exceptions from HP-UX
11.0 to 11i
All of these compatibility exceptions are rare corner cases for
well-behaved applications. Details of these exceptions can be found in
this document.
Memory Windows
This change enables applications to access up to 1GB of shared memory
that is not otherwise allocated against the system-wide limit. Enabling
Memory Windows alters the semantics of some memory API's and some
POSIX API's. These API's function correctly for applications running
within a Memory Window but do not function correctly for applications
running in different Memory Windows.
ONC+/NFS Security Correction
This change corrects a security problem in NIS+. Applications that are
linked to the archived version of the libnsl library may have a
compatibility problem. Applications linked to the shared version of
libnsl will not exhibit these symptoms. The symptoms include:
• Daemon registration will fail when UDP/TCP is used instead of the
local loopback transport device.
• In the NIS+ environment, applications will not be able to
authenticate themselves.
• There is a NIS+ performance degradation due to not being able to
contact the nis_cachemgr.
IOSCAN Usability Enhancement
This change improves the usefulness of the IOSCAN output for PCI
interfaces. The description field for PCI interface cards has been changed
to be more descriptive. See “Improved ioscan(1M) Description Field for
PCI Devices” on page 154 for more information. The description field of
non-PCI devices has remained the same. Scripts that scan for hardcoded
values may need modifications.
