Patch Name:  PHNE_3613

Patch Description: s300_400 9.0 fixes multiple ARPA Transport defects

This patch provides new fixes for:

ICMP unreachable messages can cause an error to be received on ALL
connections destined to a particular remote host, rather
than sending to the single connection which caused the destination
unreachable message to be generated.  This may be seen by an application
receiving an unexpected error 229, 242, or 239 on a socket(s).
It may also be experienced as an unexpected abort of a telnet
or ftp session. (4701-236042)

When NFS Checksumming is turned on and NFS packets are sent across
an IP gateway, NFS processes hang. (4701-236075)

Solves the problem of UDP checksum errors for inbound NFS packets that use
checksum offload network interfaces, such as loopback or FDDI. (4701-236083)

The following fixes are included:

PHNE_2509 fix: When a system NFS mounts one of it's own directories
and does a lot of writing to that directory over the mount, the NFS
daemons shut down.  When attempting to copy a large file in this
manner, the system may panic with "mclcopy_nfs: cluster too large".

PHNE_2374 fix: Sometimes when an application lets the system assign a
port number dynamically, the system erroneously assigns a port which
is not unique.  This can cause the application to hang.  This patch also
addressed the problem where a host receives an ICMP port unreachable error
and subsequently returns an error 239 (ECONNREFUSED), to all UDP connections
connected to the remote node that generated the original ICMP error.

After getting the patch onto your machine, unshar the patch
(sh PHNE_3613)

To install this patch do the following:
1) Run /etc/update (Note: you must be 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: PHNE_3613.updt" assuming
   you are in the directory where PHNE_3613.updt has been placed.  In some
   versions, you may need to enter the absolute path name.  In others, the
   default "/dev/rmt/0m" may not appear in the field as default.
5) Press "Done".
6) Move to the "Select All Filesets on Source Media" line and press "Return".

The customized script that update runs will move the original software
to /system/PHNE_3613/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended
that you move the PHNE_3613.text file to /system/PHNE_3613 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=PHNE_3613.updt of=/dev/rmt/0m bs=2048
