Patch Name: PHNE_14074 Patch Description: s700_800 10.20 HSC FDDI cumulative patch Creation Date: 98/02/06 Post Date: 98/02/12 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: HSC FDDI B.10.20.01 B.10.20.02 Filesets: FDDI-HSC.FDDI3-KRN,B.10.20.01 FDDI-HSC.FDDI3-KRN,B.10.20.02 Automatic Reboot?: Yes Status: General Superseded Critical: Yes PHNE_14074: MEMORY_LEAK When multicast packets are received on the HSC FDDI link, the driver leaks memory. Path Name: /hp-ux_patches/s700_800/10.X/PHNE_14074 Symptoms: PHNE_14074: 1. When multicast packets are received on the HSC FDDI link, memory is leaked in the driver. The system eventually runs out of free memory. 2. Multicast packets cannot be sent or received by applications on the HSC FDDI link. PHNE_13190: 1. The HSC FDDI link does not work on D-class 210/310, 220/320 and 230/330 systems. ioscan(1M) shows that the HSC FDDI card is unclaimed. 2. When the HSC bus contention goes high which means many other devices are sharing the same HSC bus with the HSC FDDI link and the HSC bus is heavily used, the HSC FDDI link has too many transmit and receive errors. Defect Description: PHNE_14074: 1. The driver relies on upper layers of the networking stack to free the memory allocated for the packets that are received. When multicast packets are received, they are not sent to the upper layers and consequently the memory allocated is not freed. 2. When checking for multicast packets (while sending or receiving data) the driver erroneously assumes that the link-level multicast address is in canonical format, while, in reality, the address is in wire format. PHNE_13190: 1. The HSC FDDI uses the node "id" property to identify a T600 system. The D-class 210/310, 220/320, and 230/330 systems do not have the "id" property defined. Thus, the HSC FDDI link does not get initialized. 2. The high error rate problem is caused by a combination of contention on the HSC bus and the small amount of memory (8K bytes) on the HSC FDDI card. The problem is seen easily if the HSC FDDI card has been put in the Core HSC slot on a K-Class system. Although the "lanadmin -S tx_threshold" command can adjust the card transmit buffer for the outbound data, in a heavily used bus, the inbound data shows many receive errors. A special setting "lanadmin -S 0" is introduced in this patch. Using this will result in a decrease in HSC bus contention.

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_14074 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_14074.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_14074.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_14074. 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_14074.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_14074.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
