I have uploaded new daily builds to their usual location:

   /afs/athena.mit.edu/user/j/a/jaltman/Public/OpenAFS/
   \\afs\athena.mit.edu\user\j\a\jaltman\Public\OpenAFS\
   http://web.mit.edu/~jaltman/Public/OpenAFS/

The list of changes since 1.3.71 include:

   * smb_ReceiveCoreRename() was factored to produce smb_Rename()
     which is used by both the original function and the new
     smb_ReceiveNTRename().  smb_ReceiveNTRename() supports the
     creation of HardLinks in addition to Renaming.  smb_Link()
     is a new function which creates HardLinks via cm_Link().
     cm_Link() is a new vnodeops function which creates links
     using RXAFS_Link().

     smb_ReceiveNTRename() does not support the File Copy and
     Move Cluster Information operations described in its interface.
     ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.

   * When opening files via symlinks, we should follow the symlinks
     until we reach the actual file stat cache entry.  The stat cache
     entry of the file should then be stored in the FID instead of
     stat scache entry of the symlink.

   * return bad operation errors for all unimplemented functions
     even if we do not know the functions exist.

   * Log bad packets and unknown operation packets to the trace log

   * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
     0xC09820FF

   * Update list of known CIFS operations to include all those listed
     in CIFS-TR-1p00_FINAL.pdf.


You can create Hard Links in AFS using JPSoft's 4NT.EXE built-in 
command: MKLNK <source> <link>.  If you are not currently using 4NT.EXE 
I strongly recommend it.  http://www.jpsoft.com/.

Softlinks can be created and removed using the softlink.exe tool which
is part of the OpenAFS distribution or the Explorer Shell AFS menu.

Does anyone believe that a "Create Hardlink ..." menu item should be
added to the Explorer Shell AFS menu?  I noticed that Windows provides
absolutely no UI for the creation of hard links even though it is 
supported by the base Win32 File APIs.

There will soon be a 1.3.72 release issued primarily for Unix.  Even 
though there is no pressing reason to issue a new build for Windows I
will package one just in case people want to have support for hard and
soft links.
