Creation Date: 00/08/31

Post Date:  00/10/02

Hardware Platforms - OS Releases:
	s700: 10.20
	s800: 10.20

Products: N/A

	OS-Core.UX-CORE

Automatic Reboot?: No

Status: General Release

Path Name: /hp-ux_patches/s700_800/10.X/PHCO_22275

Symptoms:
	PHCO_22275:
	Program abort.

	PHCO_15344:
	No visible symptoms.

	PHCO_14213:
	'df -k' with certain types of file systems,
	such as AutoFS, will coredump.

	PHCO_13982:
	This patch allows df to display input for
	very long file/path names.  For example,
	if a file system is mounted on
	/usr/TST90123456789012345678901234567890,
	executing 'df' will properly display it.
	However, if you 'cd /usr' and do

	 df TST90123456789012345678901234567890

	df will fail with:

	 df:open of /usr/TST901234567890123456789012
	 	failed.

	PHCO_13843:
	This patch is part of the 10.20 ACE 2 bundle
	which adds networking enhancements to 10.20.
	New networking features supported in ACE 2
	include NFS Version 3.0, AutoFS, and CacheFS.

Defect Description:
	PHCO_22275:
	Buffer overflow.

	Resolution:
	Modify df(1m) to check the length of the buffer.

	PHCO_15344:
	Remove fileset-level checkinstall script added for ONC+
	Networking Enhancements bundle to avoid manufacturing
	conflicts.

	PHCO_14213:
	For certain types of file systems, such as
	AutoFS, one calculation to provide the
	data when 'df -k' is used may cause a division
	by 0, resulting in a coredump.  The calculation
	has been adjusted to return 0 in such cases.

	PHCO_13982:
	The df command was relying on the 'f_fstr'
	value returned from statvfs to determine the
	mount point.  This value is not reliable
	since it is limited to 32 chars, and is
	not necessarily the mount point since it
	is simply a 'file system specific string'.
	A new method has been added to correctly
	identify the file system mount point.

	PHCO_13843:
	New functionality to support networking features
	in 10.20.
