+This file is a rough list of known issues with the 1.3.87 release of OpenAFS
on Windows. This list is not complete. There are probably other issues
which can be found in the RT database or on the mailing list.
(3a) IP address changes cause the service to terminate due to an assertion
in smb_Listener() thread.
-(3b) New IP addresses do not get bound
+(3b) New IP addresses do not get bound to the SMB server
(3c) Loopback adapter hack:
(i) prevents use of AFS Gateway
(iii) the list of hack adapters is incomplete (VMWare, MS TV/Video, ...)
(iv) incompatible with Windows 2000 and earlier
-(4) Performance of the AFS Client Service code simply sucks. The average
-read, write, and delete times for AFS are more than ten times slower than
-the equivalent Windows File Share operations. The Window File Share operations
-are not all that fast. It has been claimed that the Windows AFS functions are
-one hundred times slower than the equivalent operations on Linux. I would not
-be at all surprised. The best we can do without rewriting AFS as a IFS would
-be to match the Windows File Share performance. I believe the threading model
-is imposing significant delays in the movement of data from between the SMB
-and RX protocol operations. There was also an issue with large numbers of
-page faults which have since been fixed.
+(9) Convert to IFS!!!!!!
-(7) There appear to be directory locking problems associated with renaming
-directories.

users logging in via Integrated Logon or using afscreds.exe cannot
be automatically prompted for different cells
-(13) AFS Integrated Logon:

+(12) AFS Integrated Logon:
+(12b) If using Kerberos, need to figure out a means of passing credentials
into the user space until such time as I finish the new credential
cache service.
-(13c) If network is not available must store the username and password
+(12c) If network is not available must store the username and password
somewhere until such time as the network starts.
-(14) Loopback adapter is not always installed with bindings to "File and
- Printer Sharing for Microsoft Networks" or "Client for Microsoft
- Networks". If these are not bound then SMB names will successfully
+(13) Loopback adapter is not always installed without bindings to "File and
+ Printer Sharing for Microsoft Networks" and with bindings to "Client for Microsoft
+ Networks". If these are not bound correct then SMB names will successfully
be published to a list of zero which causes the AFS not to function.
We need a way to test whether the Loopback adapter is properly bound
so we know if it is safe to use. Actually, it is worse. Even with
the bindings on Win2000 the loopback adapter frequently fails to publish
SMB names. Of course, the error messages report nothing.
-(15) If a drive mapping is "in use", then afscreds cannot be used to Modify
+(14) If a drive mapping is "in use", then afscreds cannot be used to Modify
or Delete the Mapping. If a map to "H:" to \afs\cell\foo" with
description "home" is modified to point to \afs\cell\bar, then the
description must be unique. "home" cannot be reused. We need a way
to remove "home" from the submount list.
-(16) WinAFS configuration values are still stored in old style INI files
- instead of using the Registry. This is especially important for
- per-user values such as drive mappings
-
-(17) Drive mappings are lost on WinXP after return from Standby. (This could
- be because the AFS Client Service fails OR because the RX protocol is
- temporarily unable to access the Cell due to network restore timing
- issues.)
+ [Actually, an end user should not be able to modify the submount list]

+(16) No support for Unicode CIFS/SMB data structures. OEM Code Pages prevent
the use of interoperable file names; force the use of paths no longer
than 256 characters; force share names to be no longer than 13
characters; restrict authentication to ASCII only names and passwords;
etc.

+(24) The User Interface needs to be re-designed to separate the per-user
and per-machine settings. All of the new registry items need to
be added to the UI
-(27) There appears to be a thread safety issue in the Rx library when
- running on Intel processors which support hyper-threading
-
-(28) Thread initialization versus Global Drive Mapping. There is no
- mechanism in the afsd_init.c to ensure that all of the threads
- complete initializing in the correct sequence. In the case of
- Global Drive Maps this is a problem because the Global Drive Maps
- can be executed prior to the completion of the SMB registration
- and service thread initialization.
-
-(29) Should we allow the AFSCACHE file to be stored in the Virtual Paging
- file as long as we do not support persistent caches?
-
-(30) CIFS Remote Administration Protocol implementation is incomplete.
+(25) CIFS Remote Administration Protocol implementation is incomplete.
Notifications are not made to requestors when the view of a file
or folder changes due to token acquisition; token expiration; or
token destruction
-(31) Microsoft Office appears to have trouble editing files of ~20MB
- or larger from within AFS. Performance is particularly slow and
- applications such as Word often crash upon saving the files.
-
+(26) Remove submount creation as a side effect of AFS drive mapping.
+
+ The AFS Submount is effectively a server side alias for a path
+ located in the AFS space. This alias is exported by the AFS
+ SMB/CIFS Server to the Windows SMB/CIFS client as a Share name.
+ This makes the AFS Submount a system global setting which should
+ only be modified by a member of the "AFS Client Admin" group.
+
+ afs_creds.exe and afs_config.exe should be modified to no longer
+ use submount names when creating drive maps. Drive maps should
+ simply use the full AFS path name. Submounts should not be
+ created as a side effect of a drive mapping.
+
+ The creation of submounts should only be possible via afsshare.exe
+ or by the new AFS Client Service Administration tool when executed
+ by an authorized user.
+
+(27) No support for byte range locking (or locking at all)

List of unfunded projects:
1. No longer use AFS Client Service "cell" as the default cell for individual users
- 2. Re-write afsd_service.exe to perform synchronized thread startup and shutdown.
