Patch Name: PHNE_13800 Patch Description: s700_800 10.20 Cumulative Mux and Pty Patch Creation Date: 98/01/13 Post Date: 98/01/29 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: N/A Filesets: OS-Core.CORE-KRN OS-Core.UX-CORE Automatic Reboot?: Yes Status: General Superseded Critical: Yes PHNE_13800: HANG PHNE_8415: CORRUPTION PHNE_7601: HANG Path Name: /hp-ux_patches/s700_800/10.X/PHNE_13800 Symptoms: PHNE_13800: 1 System may hang during reboot due to pty and mux2 deadlock. 2 VTIME parameter is not working correctly when non-blocking select()'s are used in a loop. 3 Zmuxdiag does not test J2096A Mux. PHNE_10601: 1 VTIME parameter is not working correctly when asynchronous I/O is enabled - SIGIO is not being generated. 2 RTS/CTS hardware flow control signals are not reset when a direct port is closed. PHNE_9438: 1 Console output suspended leading to possible hung system. 2 A delay in character processing is observed when EOF characters are received while the terminal is in canonical mode and then switches to raw mode. PHNE_8415: Data loss observed when using block mode termio over a telnet connection. PHNE_7601: System appears hung while running telnet sessions. Defect Description: PHNE_13800: 1 System may hang during reboot due to pty and mux2 deadlock. No equivalent patches currently available with this fix. 2 VTIME parameter is not working correctly when non-blocking select()'s are used in a loop, because each call to select() may cancel a previous inter-character timer. No equivalent patches currently available with this fix. 3 Zmuxdiag does not test J2096A Mux. Equivalent Patches available for this fix: PHNE_12189: s800: 10.30 PHNE_13246: s800: 9.00 9.04 PHNE_10601: 1 VTIME parameter is not working correctly when asynchronous I/O is enabled - SIGIO is not being generated. 2 RTS/CTS hardware flow control signals are not reset when a direct port is closed. PHNE_9438: 1 Console output suspended leading to possible hung system. This defect only occurs on systems where the console device is sending abnormally large amounts for flow control characters (XON & XOFF) to the console port. The Eliko LCD terminal is one such device. Another was a PC running an application that sent many flow control characters regardless of output flow. This defect should not be experienced by the vast majority of users. 2 A delay in character processing is observed when EOF characters are received while the terminal is in canonical mode and then switches to raw mode. PHNE_8415: Data loss observed when using block mode termio over a telnet connection. PHNE_7601: System appears hung while running telnet sessions. Telnet in infinite loop because pty (line discipline) falsely indicates that data is available..

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_13800 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_13800.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_13800.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_13800. 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_13800.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_13800.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: For S700 patch installations ignore swinstall warnings about the following files - mux2.o, mux3.o
