Changes as of 2004-06-06 daily build

Significant changes have been implemented since 1.3.64 which may be
of benefit to many users who have seen problems with early 1.3.x builds.

Daily builds can be obtained from:

As always I encourage all organizations that wish to contribute to
OpenAFS for Windows development to contact me.  Financial
contributions as well as in kind assistance are seriously appreciated.

Changes since 1.3.64:

   * Sites which have a volume ID of 0x20000001 assigned to their
     root.afs volumes have been experiencing problems with accessing
     the root.afs volume of their cell when Freelance mode has been
     active.  This was because 0x20000001 was assigned to the fake
     root.afs volume created by freelance.  The fake volume id is
     now set to 0x00000001 to prevent conflicts.

   * The timeout logic in the AFS Client Service has been wrong
     for sometime.  It is based on two different assumptions.
     First, the SMB client timeout is a fix value as was the case
     with OS/2 Lan Manager.  This assumption is incorrect.  The
     SMB timeout in Windows is a dynamic value computed based upon
     a fixed minimum timeout to which is added time based upon the
     size of the request and the performance characteristics of
     the connection.  Second, it is the responsibility of the
     SMB Server to enforce the timeout requirements of the client.
     This is untrue.  The SMB Server cannot be expected to know
     the requirements of the client.  More importantly, if the
     SMB server uses the SMB client timeout as a value to restrict
     its behavior as an RX client, the performance characteristics
     of the local SMB session would be used to prematurely terminate
     WAN connections with significantly different performance
     characteristics.

     The timeout logic has therefore been modified in the following
     manner:
      . the Lan Manager Workstation (SMB) Session Timeout is used only
        as a basis for configuring the Connection Dead Timeout
        and Hard Dead Timeout values.  The Connection Dead Timeout
        must be at least 15 seconds longer than the SMB Timeout
        and the Hard Dead Timeout must be at least double the
        Connection Dead Timeout.
      . New registry entries have been added to allow the Connection
        Dead Timeout and Hard Dead Timeout values independent of the
        Lan Manager Workstation Session Timeout
      . The test to enforce the SMB Client Timeout has been removed.
       
     One of the side-effects of removing the enforcement of the SMB
     Client Timeout is that regardless of whether or not the SMB client
     is available to receive the response (and how would the SMB server
     know) the RX protocol response can be used to update the AFS
     Client Service state for ready access by future SMB client
     requests.

     This should be the end of the "Server paused or restarting messages"
  
   * Fix "fs mkmount" command to work with UNC paths and when
     started from non-AFS drives

   * Add support for arbitrary UNC paths to the pioctl() support.
     This enables the fs commands as well as the AFS Shell Extension
     to work correctly when UNC paths are being used.

   * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
     DNS if the cell configuration cannot be determined via CellServDB

   * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
     are ever set more than once at a time
 
   * Fix the management of lists of cm_cell_t structures when using
     DNS to lookup cell information.  The previous code would fail to
     reuse the same cellID for a cell if DNS was used more than once
     for a given cell name.  When the ttl expired, a single cm_cell_t
     could be inserted into the cm_allCellsp list more than once
     producing a loop.  In addition, the vlServerp list belonging to
     the cell was not freed resulting in improper refCounting of the
     servers.

   * Add DNS support to cm_IoctlNewCell() which previous only examined
     the CellServDB file

   * Add cm_FreeServer() function and call it from cm_FreeServerList()
     to properly garbage collect cm_server_t objects
    
   * Add numVCs variable to smb.c to track the number of smb_vc_t
     objects created and use it to initialize the vcID field which
     previously was set to 0 in all objects resulting in FindByID
     collisions.

   * Fixed DNS lookups to work consistently throughout the OpenAFS
     product instead of just from within the afsd_service.exe

   * Added a runtime check to ensure that AFS Client Service SMB
     Server is accepting connections before attempting to mount
     global drives.

   * Read IP addresses for volume servers out of the CellServDB
     file if gethostbyname() on the hostname fails.

   * Fix getcellconfig() to populate both the Hostnames as well
     as IP addresses when loading cell data via DNS

   * Increase the Connection Dead Time to 50 from 20 seconds
     Increase the Hard Dead Time to 120 from 40 seconds
     (matches the Unix values)

   * Fixed an assertion validating the number of allocated NCBs

   * Fixed the build environment to consistently build for
     Windows 2000 and above.  (APPVER = 5.0)

   * Fixed rx_debug to properly validate the receipt in incoming
     data with select() and recvfrom().  Do not copy data out of
     the socket buffer unless success is indicated.
