WAN-DUNIX WANOSF_E03030 WAN Support Tru64 UNIX ECO Summary

TITLE: WAN-DUNIX WANOSF_E03030 WAN Support Tru64 UNIX ECO Summary Modification Date: 31-MAR-1999 Modification Type: Updated Kit Supersedes WANOSF_E02030 Copyright (c) Compaq Computer Corporation 1998, 1999. All rights reserved. PRODUCT: WAN Support for Tru64 UNIX Systems OP/SYS: Compaq Tru64 UNIX (formerly DIGITAL UNIX) SOURCE: Compaq Computer Corporation ECO INFORMATION: ECO Kit Name: WANOSF_E03030 ECO Kits Superseded by This ECO Kit: WANOSF_E02030 WANOSF_E01030 ECO Kit Approximate Size: 520 Blocks TAR file - 520 Blocks Kit Applies To: WAN Support for Tru64 UNIX V3.0, V3.0A, V3.0B Compaq Tru64 UNIX V4.0 through V4.0E System/Cluster Reboot Necessary: No ECO KIT SUMMARY: An ECO kit exists for WAN Support for Compaq Tru64 UNIX V3.0 and V3.0B on Compaq Tru64 UNIX V4.0 through V4.0E (formerly DIGITAL UNIX). Problems addressed in this WANOSF_E03030 kit: o Corrections made to /usr/var/subsys/wdd_pwa.mod and /usr/lbin/wddsetup The change to wdd_pwa.mod modified the logic to recognize and configure the PLX 9080 based PBXDP boards. The wddsetup script was modified to change the 3 PCI_Option entries that identified the prototype (non production) PBXDP boards to identify the 2, 4, and 8 port PLX 9080 based PBXDP boards. These entries are placed in the /etc/sysconfigtab file after "wansetup KERNEL" is executed to configure the PCI card as part of the WAN configuration. o Corrections made to /usr/sbin/x25applicationd The change to x25applicationd allows the operator to disable x25 access applications from within NCL without causing x25applicationd to exit as a result of an interrupted system call. o Corrections made to /usr/sbin/x25applicationd The change to x25applicationd eliminates the defunct processes that are left on the system when x25applicationd's child processes terminate. o Corrections made to /usr/var/subsys/wdd_pwa.mod The change to wdd_pwa.mod corrects the clock speed so that data is transmitted at the expected rate when the system is configured to run with the internal clock on the PBXDP card. Problems addressed in WANOSF_E02030: o Corrections made to libx25.a, libx25_r.a, and libx25.so libraries The library function X25ClosePort function has been modified to clean up all internal data structures prior to releasing the socket file descriptor. Multithreaded programs that open and close X25 ports within threads will no longer generate a segmentation fault in X25TestState. o Corrections made to libx25.a, libx25_r.a, and libx25.so libraries The library function X25Encode function was changed to correctly calculate the length of list items that are put in EPLs. o Corrections made to wdd_datalinks.mod The change to wdd_datalinks.mod allows the user to issue NCL commands to disable and enable LLC2 without causing the system to crash with a "kernel memory fault". o Corrections made to wdd_pwa.mod and wddsetup The change to wdd_pwa.mod limits the EMULEX Xp-Series/Sync/Async PCI cards that will be configured by the driver to the cards supported by WAN Support for Digital UNIX Systems. The change to wddsetup removed unsupported EMULEX card entries that wddsetup put in the /etc/sysconfigtab file. o Corrections made to wdd_datalinks.mod The change to wdd_datalinks.mod results in LLC2 reinitializing when it receives a DM when in the running state. o Corrections made to x25_access.mod The change to x25_access.mod allows a program makes multiple X.25 calls. The X25Decode library function no longer randomly returns an X25RC_BADEPL error. o Corrections made to wdd_datalinks.mod The change to wdd_datalinks.mod results in LAPB configuration for the EMULEX PCI cards (pwa) to be maintained through a system reboot. o Corrections made to wdd_pwa.mod The change to wdd_pwa.mod corrected the consistency check problem described in QAR 61026 (ECO 1). o Corrections made to x25config The change to x25config eliminates the problem where duplicate entries for IP over X.25 are put into the /sbin/rc3.d/X28.50x25 file by wansetup when it used to make modifications to the configuration. o Corrections made to x25config The change to x25config allows the program to exit without crashing after adding more than one IP over X.25 host. o Corrections made to wdd_datalinks.mod The change to wdd_datalinks.mod provides notification to SNA peer server, eliminating a hang, when the LLC2 connection is disconnected. o Corrections made to x25_access.mod The change to x25_access.mod provided the capability to enable D-bit processing. o Corrections made to isdnccd The change to isdnccd allows a host's alias to be used by rlogin. o Corrections made to isdn_ppp.mod The change to isdn_ppp.mod allows isdnccd to be started from the command line to initiate an IP over ISDN call without crashing. Problems addressed in WANOSF_E01030: o On lines with full modem control, ensure the "interrupt on transmit underrun" bit gets set so that the driver will be informed of the underrun and clear the condition. (This bit was already set on lines with no modem control.) Without this change, transmission will stall until the user of the line issues a "driver abort". The datalink protocols LAPB and HDLC will issue a "driver abort" when resetting the protocol, for example in response to other end of the link issuing a protocol reset because they haven't heard from the stalled end for a long time. Other users of the line may not ever normally issue a "driver abort". o The driver was performing consistency checks on buffer addresses and issuing a panic call, which would crash the system, if the check failed. The check was failing on large memory systems (e.g. > 2GB). The check has been removed. o The driver was not calling the Common Trace Facility (CTF) to trace transmitted and received frames. INSTALLATION NOTES: The load procedure will verify that the correct subsets are loaded on the system prior to loading the subsets that have been updated with ECO 3. Extract the tar kit into a temporary directory. Change directory to the directory containing the extracted tar file and use the following command to load the new subsets: setld -l . If the load procedure detects any errors it will provide advice on how to fix the problem. After the kits have been loaded, follow the directions provided during the loading phase to configure WAN into the kernal.
