	PHNE_16132: PANIC
	PHNE_10831: PANIC

Path Name: /hp-ux_patches/s700_800/10.X/PHNE_16132

Symptoms:
	PHNE_16132:
	System panic type 15 in pckt_rsrv in the Streams pty code.

	PHNE_12038:
	ioctl TCFLSH failed to work on Streams PTY.

	PHNE_10831:
	System panic at ldtty_copymsg() in streams pty code.

	PHNE_10174:
	Characters are not echoed as they are typed until
	VMIN is reached.
	Rlogin does not use the defaults from stty < /dev/ttyconf

Defect Description:
	PHNE_16132:
	The type 15 panic was caused the b_rptr pointer in the
	mblk being overwritten by a bad value when M_FLUSH was
	being processed and the system ran out of memory.

	PHNE_12038:
	This problem was caused by a miss handling of M_FLUSH
	message on the Packet Mode module on the Streams PTY.

	PHNE_10831:
	This panic was caused by the fact that ldtty_copymsg()
	was referencing a streams message that has already been
	freed.  This happened when the streams pty is in raw mode.

	PHNE_10174:
	The first problem was caused by the fact that the VTIME
	timer was not started until a read is pending.  Since
	the application was using select, no read was pending.
	As a result, data were not available for read until the
	VMIN requirement is met.
	The second problem was due to the fact the /dev/ttyconf
	feature was not implemented on Streams PTY which is used
	by rlogind starting HP-UX 10.20.  The /dev/ttyconf feature
	is a new feature added to the BSD line discipline recently
	to provide backward compatibility.  It was not expected
	that users would need this feature on Streams PTY.

Installation Instructions:

	before installing this patch.
	------------------------------------------------------------
	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 PHNE_16132

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_16132.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/PHNE_16132.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/PHNE_16132.  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 PHNE_16132.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/PHNE_16132.depot of=/dev/rmt/0m bs=2k
