Patch Name: PHKL_18935

Patch Description: s700 10.24 (VVOS) Audit Write Returns Incorrect Data Count

Creation Date: 99/06/17

Post Date:  99/06/21

Hardware Platforms - OS Releases:
	s700: 10.24

Products: N/A

Filesets:
	VirtualVaultOS.VVOS-KRN

Automatic Reboot?: Yes

Status: General Release

Critical: No

Path Name: /hp-ux_patches/s700/10.X/PHKL_18935

Symptoms:
	PHKL_18935:
	If a process writes an application audit record and audit is
	disabled, the write() system call returns that no bytes have
	been written.  This could cause an application written with
	user threads to hang.

	PHKL_18659:
	System panics with message:
	"panic: malloc: allocation too large"

	PHKL_10407:
	Under certain conditions when system auditing
	is enabled, the audit statistics available from
	auditcmd -c will show that the configured limit
	for audit space used has been exceeded.

Defect Description:
	PHKL_18935:
	audwrite() returns an incorrect count when audit is
	disabled.

	PHKL_18659:
	The audit record allocation algorithm was changed to make
	it more efficient with all types of audit records.

	PHKL_10407:
	Under heavy system load with auditing enabled,
	the kernel memory area used to hold audit records
	queued for delivery to the audit daemon can
	use more memory than configured limit for audit
	space memory usage.

	This is a temporary condition and the audit
	daemon will return the excess memory to the
	system as it processes audit records.

Installation Instructions:

	------------------------------------------------------------
	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 PHKL_18935

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHKL_18935.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHKL_18935.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHKL_18935.  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.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHKL_18935.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/PHKL_18935.depot of=/dev/rmt/0m bs=2k
