Path Name: /hp-ux_patches/s700_800/10.X/PHCO_18137

Symptoms:
	PHCO_18137:
	The restore command core dumps when restoring a dump of a
	file system with a large number of inodes.

	PHCO_14417:
	restore(1m) was unable to read some cross-platform
	dump archives under 10.20 that were readable under
	previous releases.

Defect Description:
	PHCO_18137:
	When restoring a dump of a file system with a very large
	number of inodes, the restore command core dumps while
	attempting to extract the inode map.  The software defect
	begins to be a problem when the maximum number of inodes
	for a file system is approximately 4 million, though it
	does not core dump and may not have any other visible
	adverse affects.  When the maximum number of inodes for a
	file system reaches approximately 8 million, the command
	dumps core.
	Resolution:
	When extracting the inode map, the code was using the
	s_spcl.c_addr[] array when reading in blocks of the map.
	The s_spcl.c_addr[] array has a size of 512.  If the map
	was larger than 512 blocks, restore would write beyond
	s_spcl.c_addr[512].  The new code defines a new "c_addr"
	variable which is dynamically allocated for the map
	extraction.

	PHCO_14417:
	An off-by-one error was introduced, at 10.20,
	into the restore(1m) code which deals with
	quad-swapping.

	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_18137

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_18137.depot

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_18137.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_18137.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_18137.depot of=/dev/rmt/0m bs=2k
