OpenVMS VMS721_PPPD-V0100 PPPDriver ALPHA 7.2-1 ECO Summary

TITLE: OpenVMS VMS721_PPPD-V0100 PPPDriver ALPHA 7.2-1 ECO Summary

New Kit Date     :  24-APR-2001
Modification Date:  Not Applicable
Modification Type:  New Kit
 
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-dcx_axpexe.pcsi, then it can
       be expanded by typing RUN kitname-dcx_axpexe.pcsi.  The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

ECO KIT SUMMARY:

An ECO kit exists for PPPDriver on Alpha V7.2-1.  This kit addresses the following
problems: 


  o  When the remote end of the connection requests a transfer size
     greater  than  1500  bytes,  the PPPDRIVER accepts the request
     even though its buffer cannot handle  the  size.   Connections
     cannot  be  maintained  in  this  mode because the lower layer
     recognizes the attempt at buffer overflow and  it  causes  the
     connection to abort.

        Images Affected:  [SYS$LDR]SYS$PPPDRIVER.EXE

  o  The ASNDRIVER looses an IRP (I/O request packet) for read  and
     a  TWP  (terminal  write packet) for writes.  The cleanup code
     would fail while looking for the missing IRP and TWP and cause
     an ACCVIO.

            INVEXCEPTN, Exception while above ASTDEL

     Offset:            00000CEC

        Images Affected:  [SYS$LDR]SYS$ASNDRIVER.EXE



  o  An INVEXCEPTN crash occurs when attempting to establish a  PPP
     connection after a TCP/IP restart.

        Images Affected:  [SYS$LDR]SYS$PPPDRIVER.EXE

  o  A port hangs when a timing error  causes  the  port  state  to
     change before all pending I/Os have completed.

        Images Affected:  [SYS$LDR]SYS$PPPDRIVER.EXE

  o  A  PPP  disconnection  of  a  remote  client  could  cause  an
     INVEXCEPTN crash.

INSTALLATION NOTES:

The images in this kit will not take effect until the system is
rebooted.  If there are other nodes in the VMScluster, they must 
also be rebooted in order to make use of the new image(s).  

If it is not possible or convenient to reboot the entire cluster at 
this time, a rolling re-boot may be performed.
