Patch Name: PHNE_18525 Patch Description: s700_800 10.20 Streams PTY cumulative patch Creation Date: 99/05/04 Post Date: 99/05/14 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: N/A Filesets: Streams-TIO.STRTIO-KRN Automatic Reboot?: Yes Status: General Superseded Critical: No (superseded patches were critical) PHNE_16132: PANIC PHNE_10831: PANIC Path Name: /hp-ux_patches/s700_800/10.X/PHNE_18525 Symptoms: PHNE_18525: Resizing a window on busy PTY pair causes the window to hang. PHNE_14975: Streams pty did not work in UTF8 environment. This patch is an enhancement that provides UTF8 support. 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_18525: If a window is resized when there is a lot of activity on the window, the window hangs. Resolution: The fix was to not use flow control for the high priority messages like M_IOCACK and M_IOCNAK. These messages were sent upstream to the STREAMS head, even when the STREAMS head was flow-controlled. PHNE_14975: This patch is an enhancement for UTF8 support for STREAMS pty line discipline. 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.

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_18525 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_18525.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_18525.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_18525. 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_18525.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_18525.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
