DECnet/OSI DNVOSI_E12063 DECnet/OSI V6.3 For OpenVMS VAX ECO Summary
TITLE: DECnet/OSI DNVOSI_E12063 DECnet/OSI V6.3 For OpenVMS VAX ECO Summary
 
New Kit Date:       18-APR-2000
Modification Date:  01-MAY-2001
Modification Type:  Correcting broken links

NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname.pcsi-dcx_axpexe, then it can
       be expanded by typing RUN kitname.pcsi-dcx_axpexe.  The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

Problems Addressed in DNVOSI_E12063:

Corrections for Base Components

Corrections made to SYS$LIBRARY:CDI$SHR.EXE
       - Add support for sticky cache entry.
       - Set default cache expiration timer to 0 (ie infinite),
         not either 7 or 30 days.
       - Convert old V1.0 and V2.2 cache files to V2.3 cache files
         to preserve cache with upgrades.
       - Allow sticky cache entry even when sys$fullname is not defined.
      - ASTs needed to be disabled longer to protect the node information
         data structures from being corrupted.
       - Modify cache write logic around sticky bit changes.
       - Prevent access violations for some string manipulations in
         CDI search path.
       - Prevent system crash on return to session control with an
         invalid node parameter.

Corrections made to SYS$SYSTEM:CTF$DCP.EXE
       - Add spinlocks so that two undeclare threads are forced to run
         serially in SMP environments.

Corrections made to SYS$SYSTEM:NCL.EXE
       - CMIP encoding/decoding correction for "CML-E-INVALID_PDU".
       - Add support for "With" clause.
       - Modifed SetDefaultEntity, SetDefaultAccess and SetDefault routines
         to correct memory allocation and new defaults.

Corrections made to SYS$UPDATE:DECNET_MIGRATE:
       - Include COLLECT and SHOW PATH correction for the error
        "Unsupported primary directory service."
       - Correct MOP Client NCL Script load file name.

Corrections made to SYS$STARTUP:DNS$CLERK_STARTUP.COM:
       - Allow the user to specify the location of the NCL script
         via logical name definitions.

Corrections made to SYS$LIBRARY:DTSS$SHR.EXE
       - Modify user callable DTSS routine "mulftime" as this returned
         a value that is inaccurate starting with the lsb of the high
         order longword, with all lower order longwords being similarly
         inaccurate.

Corrections made to SYS$STARTUP:DTSS$STARTUP.COM:
       - Allow the user to specify the location of the NCL script
         via logical name definitions.

Corrections made to SYS$SYSTEM:DECNET_REGISTER:
       - Correct search for Phase IV node name database in SYS$COMMON.
       - Use DECdns high confidence to register nodes correctly.
        This prevents the error:
         %DNS-E-UNKNOWNENTRY, Requested name does not exist.
         After the initial error, the node object was deleted, but
         the .DNA_BackTranslation was left so that subsequent attempts
         to register the node failed with "name already in use".

Corrections made to SYS$UPDATE:DTSS$INSTALL_TIMEZONE_RULE.COM:
       - Prevent procedure from looping if SYS$LOCALTIME is defined to
         a value that doesn't exist in the list of valid timezone rules.

Corrections made to SYS$UPDATE:DTSS$TIMEZONE_RULES.DAT:
       - Change DTSS MET time zone rule for 1996 and 1997
         daylight savings time from the last Sunday in September
         to the last Sunday in October.  NET$CONFIGURE.COM must
       - Prevent procedure from looping if SYS$LOCALTIME is defined to
         a value that doesn't exist in the list of valid timezone rules.
         be run to update the rule.

Corrections made to SYS$SYSTEM:NCP
       - Prevent possible access violation with proxies.
       - Correction for Show Known Nodes Characteristics.

Corrections made to SYS$SYSTEM:NET$ACP
       - Included for support of CDI$SHR.

Corrections made to SYS$SYSTEM:NET$CCR.EXE:
       - Modify "%CCR-F-UNRCMIPRSP, unrecognized CMIP error status" to
         "%CCR-F-ACCESSDENIED, NET$MANAGE, NET$DIAGNOSE or BYPASS req"

Corrections made to SYS$MANAGER:NET$CONFIGURE.COM:
       - Correct the use of SYS$COMMON for DECnet Migration
         temporary files.
       - Require LOCAL in the Session Control Search Path
         on DECdns servers.
       - Correct the use of logical name definitions for script
         files.
       - NET$STARTUP_RENAME.COM could be created with an invalid
         node name.
       - Add a Flow Control Policy Option for NSP Transport.
       - Correct DCL command syntax error on NSP configuration
         section within option 4.
       - Modify error handling on temporary files.

Corrections made to SYS$SYSTEM:NET$EVENT_DISPATCHER:
       - Included for compatibility with NET$PROCESS_EMAA.

Corrections made to SYS$UPDATE:NET$CONVERT_DATABASE:
       - Remove erroneous log file message "found 0 nodes".
       - Prevent database conversion to an invalid command:
         "SET NODE 0 CSMA-CD STATION MNA-0 STATION BUFFERS 15"
         in NET$CSMACD_STARTUP.NCL.
       - Add support for the DEFPA device.
       - Convert the Phase IV routing maximum visit count of 255 to
         the Phase V limit of 63.
       - Properly convert FDDI device, DEFPA, from Phase IV. The
         communications port should have been FWA not FPA.

Corrections made to SYS$LOADABLE_IMAGES:NET$ALIAS.EXE
       - Correctly configure multiple aliases.
       - Prevent alias hang on startup. If NET$ACP was very busy,
         the alias task could sometimes get suspended while
         holding the object lock in exclusive mode. The solution
         is to increase the priority of the alias task.
       - Correct alias selection weight of one.
       - Correct the format of the Phase V node address in Alias
         forwarding packets to prevent logical links from being
         unexpectedly aborted.
       - Prevent possible system crash if the alias round robin
         queue was corrupted by disabling the AST delivery when
         the alias port was toggled.
       - Prevent startup hang during the enable while waiting
         for the Object lock that was held in exclusive mode
         by another alias member.

Corrections made to SYS$LOADABLE_IMAGES:NET$DRIVER.EXE:
       - Correct incoming disconnect with DNA where a
         a UCB could be left around.
       - Correct disconnect path that could lead to hanging
         transport ports if the outgoing connect initiate was
       - Correct mailbox disconnect message by removing
         an invalid check for a corrupt QLB queue in IO$_ACCESS.
       - Include spinlocks to synchronize all I/O completion.
       - Always delete the session association when an incoming
         connection times out.  If many incoming connections failed
         this could eventually lead to a resource exhaustion and
         a system crash.
       - SMP synchronization was added to the executeDeAccess
         to prevent a network device hang on a very heavily loaded
         system.
       - Prevent possible application RWAST or network device hangs with
         QIOUCB$V_closeassocdone.  Double close associations precipitated
         this modification.  Both QIO_EXECUTE and QIO_COMPLETION were
         modified to add a new bit to check if the association has already
         been closed and if the channel can be deallocated.
       - Modify disconnect data counted string to emulate Phase IV behavior
         of stepping on the first byte of user data to make it a counted
         string IF the user application did not supply this necessary count.

Corrections made to SYS$LOADABLE_IMAGES:NET$LOOP_APPLICATION.EXE:
       - Correct application loopback error "Agent is invalid"
         when connecting by destination tower.

Corrections made to SYS$SYSTEM:NET$MOP:
       - Save unnecessary disk access on dump requests.
       - Add a new diagnostic error for Console Carrier Request
         "CCR$_DuplicateAddr, duplicate address error" to help
         resolve a configuration error.
       - Prevent SSRVEXCEPTN crashes in NET$MOP.

Corrections made to SYS$LOADABLE_IMAGES:NET$MOPS0.EXE:
       - VAX only correction for a kernel dispatch table
         to a nonpaged psect.

Corrections made to SYS$LIBRARY:NET$PROCESS_EMAA.EXE:

      - Prevent possible system crash with a negative or zero
         entity count in the IVK.

Corrections made to SYS$LOADABLE_IMAGES:NET$OSDRIVER.EXE:
       - Correct incoming disconnect with VOTS where a
         a UCB could be left around.
       - Prevent system crash when running a VOTS trace with a
         bad NCB descriptor.

Corrections made to SYS$LOADABLE_IMAGES:NET$OSVCM.EXE:
       - Correct lost "fillm" when a connection was not processed
         by the application before the timeout.

Corrections made to SYS$LOADABLE_IMAGES:NET$ROUTING_ES.EXE:
       - Prevent a crash when deleting a reachable address due
         to erroneous cache size.
       - Prevent possible crash in routing shutdown.
       - Prevent possible crash by discarding all invalid PDUs.
       - Event logging on Alpha was corrected.
       - Routing over HDLC check the validity of the NSAP length
         for incoming PDUs when there is no adjacency.
       - Raise the default ES cache size to 512 and allow the set es
         cache size command to work.
       - Correction for redirect PDUs that should not have been discarded.
       - Padded IS hello should not have been discarded.
       - Prevent possible crash with X.25 PVCs.
       - X.25 circuit enable code was modified to prevent possible
         corruption if the X.25 channel was disconnected.
       - Raise the maximum allowed circuits from 20 to 40.
       - Modify the use of R9 to avoid corruption in LES (Alpha only).

Corrections made to SYS$STARTUP:NET$ROUTING_STARTUP.COM:
      - Call NET$LES_STARTUP to start the LES ACP process.

Corrections made to SYS$SYSTEM:NET$SDA.EXE:
       - Alpha only correction for "NETWORK SHOW EMAA"
       - Correction for "SHOW NSP PORT"

Corrections made to SYS$LOADABLE_IMAGES:NET$SESSION_CONTROL.EXE:
       - Prevent "invalid access" with user IDs longer then 12 characters.
       - Use proxy first regardless of session attributes.
       - Add support for the configuring of multiple aliases by setting
         the outgoingalias name and default in the application.
       - Change the disconnect status sent to the remote node when
        session control is disabled on an existing connection from;
         "%SYSTEM-F-SHUT, remote node no longer accepting connects" to
         "%SYSTEM-F-THIRDPARTY, network logical link disconnected by a
         third party"
       - Prevent "PGFIPLHI, Page Fault IPL Too High", in NET$ACP on
         system boot.
       - Prevent possible incoming disconnect crash.
       - Modify session control so that breakin attempts do not occur
         when proxy access was correctly used.
       - Prevent an SMP crash with the DeclareSession completion function.
       - Modify SMP synchronization for stale association by replacing
         DSBINT and ENBINT with IOLOCK8 acquire and release in
         SSRV$$GETPORTINFORMATION routine.
       - Conditionalize out SCL spinlock checking because this check is
         now obsolete.
       - Pevent crash in NET$ACP from a bad DECdns and CDI cache entry.
         A stale pointer in DNSResult[DNSREQ$A_Pointer] with
         ACP$CheckBackTransTask could cause a double deallocation.

Corrections made to SYS$MANAGER:NET$SHUTDOWN.COM:
       - Allow DECdns Clerk shutdown to be last.
       - Prevent NET$SHUTDOWN from aborting when a NET process logical
         was defined.

Corrections made to SYS$STARTUP:NET$STARTUP.COM:
       - Node rename temporary file should only be executed if
         initial start was successful.

Corrections made to SYS$LOADABLE_IMAGES:NET$TPCONS.EXE:
       - Prevent a BGDRIVER socket leak that could under some incoming
         connect error conditions eventually cause the available
         sockets to become exhausted.
       - Prevent possible system crash on a disconnect indication.

Corrections made to SYS$LOADABLE_IMAGES:NET$TRANSPORT_NSP.EXE:
       - Prevent hang on shutdown.
       - Correct possible hang when the NSP maximim window size
         was greater then 20.
       - Disconnect data from Phase IV nodes was incorrectly reported
         as a protocol error.   When io$m_synch was used, the mailbox
         read hung waiting to receive a disconnect with optional data.
       - The default retransmits was lowered from 12 to 8 for faster
         error detection and recovery.
       - NSP connect initiate will be resent every 5 seconds instead
         of 10 seconds.  This allows NSP to timeout before session by
         default even when the remote node is not reachable.
       - NSP was corrected to prevent logical links from hanging on
         a retransmission of an interrupt message.
       - Prevent possible  NETNOSTATE  bugcheck that was caused by a
         timing window in which the connection was being torn down and
         the I/O had been cancelled while the transmit was in progress.
       - Insure that I/O will complete even if the IO$_Multiple bit is set
         in the QIO function.
      - Allow NSP flow control to be more efficient and deliver the
         XON as soon as possible after a new receive request is received.
       - Prevent a remote TCID from attempting to be reused for a
         connection if the previous connection failed to be deaccessed.
       - Corrected the possible delivery of protocol errors with disconnect
         data.  If the user string (P2) is not a counted string this will
         now be included on behalf of the user.  Phase IV did this previously,
         but removed the first byte of the user data while making it counted.

Corrections made to SYS$LOADABLE_IMAGES:NET$TRANSPORT_OSI.EXE:
       - Prevent possible crash with deactivate port.
       - Limit Maximum Alias Transport Connections to 1015.
       - Prevent possible crash when expedited data had just been
         transmitted and the message sequence number to be
         retransmitted did not match the expected message.
       - Correct Alias Transport Connection Table for connections
         using cluster alias because the TC ID range was not
         properly allocated.
       - Prevent a crash on connect initiate where the port had not
         yet been activated and the solicit VCRP was zero.
       - Prevent a crash when a port block was inserted into a queue
         in the RSP (Remote Service Provider) and an element in the
         queue found an invalid pointer.
       - Correct the checksum calculation for messages larger then
         4,399 bytes.
       - Prevent crash in OSITP disable port if this same port had
         already been disabled.
       - Remove forced bugcheck from BUILD_DATA routines.
       - Insure that I/O will complete even if the IO$_Multiple bit is set
         in the QIO function.
       - Prevent transport bugcheck when an X.25 connection was abnormally
         terminated and a protocol error was in the process of being logged.
       - Correct timing window to prevent a VCRP leak if user data could
         not be delivered to the application because it was disconnected.
       - Modify state tables such that if the port is in a WFNC state and
         receives a DR or DC, just ignore the message rather then bugcheck.
       - Correct restraint mode window.

Corrections made to SYS$LOADABLE_IMAGES:SYS$NETWORK_SERVICES.EXE:
        - Prevent possible pool corruption with X.400 or X.500.
        - Correct queue for Error MRCP with flink/blink initialization.
        - Allow more then one Error MRCP for full process entities,
          MOP and EVD.
        - Update ECO number in DECnet version "05090D"

     via logical name definitions.

Corrections made to SYS$LIBRARY:DTSS$SHR.EXE

  o  Modify user callable DTSS routine "mulftime" as this returned
     a value that is inaccurate starting with the lsb of the high
     order longword, with all lower order longwords being similarly
     inaccurate.

Corrections made to SYS$STARTUP:DTSS$STARTUP.COM:

  o  Allow the user to specify the location of the NCL script
     via logical name definitions.

Corrections made to SYS$SYSTEM:DECNET_REGISTER:

     This prevents the error:

       %DNS-E-UNKNOWNENTRY, Requested name does not exist.
       After the initial error, the node object was deleted, but
       the .DNA_BackTranslation was left so that subsequent attempts
       to register the node failed with "name already in use".

     to prevent a network device hang on a very heavily loaded
     system.

  o  The default retransmits was lowered from 12 to 8 for faster
     error detection and recovery.

  o  NSP connect initiate will be resent every 5 seconds instead
     of 10 seconds.  This allows NSP to timeout before session by
     default even when the remote node is not reachable.

  o  NSP was corrected to prevent logical links from hanging on
     a retransmission of an interrupt message.

  o  Correct Alias Transport Connection Table for connections
     using cluster alias because the TC ID range was not
     properly allocated.

  o  Prevent a crash on connect initiate where the port had not
     yet been activated and the solicit VCRP was zero.

  o  Prevent a crash when a port block was inserted into a queue
     in the RSP (Remote Service Provider) and an element in the
     queue found an invalid pointer.

  o  Correct the checksum calculation for messages larger then
     4,399 bytes.

  o  Prevent crash in OSITP disable port if this same port had
     already been disabled.

     terminated and a protocol error was in the process of being logged.

  o  Correct timing window to prevent a VCRP leak if user data could
     not be delivered to the application because it was disconnected.

Corrections made to SYS$LOADABLE_IMAGES:SYS$NETWORK_SERVICES.EXE:

INSTALLATION NOTES:

                                                                              
Install this kit with the POLYCENTER Software Installation utility 
(PCSI) by logging into the SYSTEM account, and entering the following 
command at the DCL prompt: 

     $ PRODUCT INSTALL DNVOSIECO10/SOURCE=[location of the .PCSI file]

Note that you can use the DECwindows Motif interface to PCSI if you wish.

For the corrections in this kit to take effect, the system must be
rebooted.  If the system is a member of a VMScluster, the entire
cluster must be rebooted.  Rebooting the system can be postponed if
it is not convenient to reboot when the kit is installed.  However, 
the new driver(s) will not take effect until after a reboot.

Installation Caution

After the installation of this ECO kit, an error in the POLYCENTER
Software Installation (PCSI) prevents installation of the OSAK SPI 
Interface V3.0.

The OSAK PCSI installation requires DECnet/OSI V6.3, which causes the 
installation process to remove DNVOSIECO12.  This situation leaves the 
system without a SYS$NETWORK_SERVICES.EXE file.  Therefore, the system
cannot be rebooted.

You must preserve the original installation order, indicated below. 
This will be corrected in a future release.

Installation Order

  Place each PCSI kit in a unique source directory

    1) DECNET_OSI V6.3 /Source=[KITS.DECNET]
    2) OSAK V3.0-L /Source=[KITS.OSAK]
    3) FTAM V3.2-F /Source=[KITS.FTAM]
    4) DNVOSIECO10 V6.3 /Source=[KITS.ECO]
