2 * The afs_config.exe submounts dialog had two errors.
3 First, attempts to remove entries failed because the registry
4 key was being opened without KEY_WRITE privileges.
5 Second, when editing a submount entry, changing the name
6 would add a new key and leave the original one in place.
7 Now the original submount will be removed if its name is
10 * In recent months there have been several incidents in which
11 users have experienced problems starting or accessing
12 afsd_service.exe and after significant effort has been spent
13 it has turned out that they have two versions of AFS on the
14 machine or an inconsistent set of DLLs.
16 Code has now been added to afsd_service.exe which will walk
17 the list of modules loaded by afsd_service.exe and validate
18 that the version of the AFS DLLs matches the version of the
19 afsd_service.exe executable. If they do not match the service
22 * When Freelance mode is enabled and there is no registry
23 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
24 will attempt to import the afs_freelance.ini file contents.
25 If the file does not exist, it was creating a dummy file
26 with a r/o and r/w entry for the default cell and then
27 importing those values.
29 This process has been changed. The temporary file is no
30 longer created. Also, both the OpenAFS Client install
31 directory as well as %WINDIR% are checked for previous
32 afs_freelance.ini files.
34 * Added support for VL_GetEntryByNameN(). Still need to add
35 support for VL_GetEntryByNameU() for multi-homed support.
37 * Fix a deadlock situation in afscreds.exe when canceling an
38 auto-generated Obtain Tokens dialog
41 * Fix the locking of objects during Directory Searches in the
42 SMB/CIFS server. The failure to properly lock the reference
43 counts was resulting in the premature freeing of smb_dirSearch_t
44 objects while they were still in use by the SMB/CIFS client.
45 This does not solve the "Invalid Handle" problem.
47 * Fix Find Cell By Name pioctl call to return a valid cell
48 name for the Freelance fake root.afs volume.
49 "Freelance.Local.Root".
51 * Fix the Explorer Shell Extension Symlinks->Add operation.
52 The dialog template was missing and the link destination
55 * Add support for symlinks to Freelance root.afs volume
56 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
57 <number> = "<linkname>:<relative-path>."
58 Use symlink.exe to create, list, or remove
60 * Remove the fallback to the use of KFW's KRB4 library when obtaining
61 tokens. We never obtain KRB4 tickets.
63 * Fix AFS Client Configuration Control Panel to support new SysName
65 * Fix a bug in afsd_service.exe which could result in the SysName
66 not being read from the registry.
69 * Add code to block the issuance of AFS tokens by aklog.exe or
70 afscreds.exe when the Kerberos 5 principal name contains a dot.
72 * Modify the IsAdmin() function to always treat the local SYSTEM
73 account as an AFS client administrator. Affects fs.exe and
76 * Modify the internal handling of Quota Exceeded errors
78 * Upgrade all reference count fields in the Windows cache manager
79 and the osi library to use unsigned long instead of signed short.
80 A similar fix has been applied to the afs rpc (rx) library.
82 * fix the Windows cache manager to prevent it from replacing the
83 rx_connection object associated with the cm_conn_t object on each
84 and every operation if "fs crypt" was set. This explains the
85 dramatic performance difference when crypt is used vs clear.
86 The problem: 'cryptall', a boolean flag indicating whether or not
87 "fs crypt" is set, was being compared to the rx_connection
88 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
89 1 != 2 and therefore the rx_connection was always destroyed
90 and replaced on each and every operation.
92 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
93 It is not safe for the cm_conn_t object to not be locked because
94 rx_DestroyConnection might be called from another thread if:
95 - the user's tokens have changed or expired
96 - the crypt mode has changed
98 This fix appears to have also taken care of the problems associated
99 with Overlapped Writes resulting in Delayed Write errors.
101 * fix NSIS installer's AdminGroup.exe to properly create and
102 remove groups when given -create or -remove. The string comparison
105 * fs sysname now accepts a list of sysname values
107 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
108 DWORD which when set to a non-zero value will cause error message
109 text to be output to stderr from the pioctl() routine. Useful in
110 debugging failures of fs.exe, tokens.exe, etc.
112 * added a test to the power management code to only perform a
113 flush operation if there is at least one network adapter which
114 is not a loopback adapter.
116 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
117 "EnableKFW". This value will not be read if the key
118 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
119 value under that key does not.
121 * provide mechanisms to force the use of krb524d for Kerberos 5
122 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
123 there is a new registry value "Use524" and for aklog.exe a new
124 command line parameter "-m".
126 * Fix the pattern matching algorithm to properly match patterns
129 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
130 which is used by both the original function and the new
131 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
132 creation of HardLinks in addition to Renaming. smb_Link()
133 is a new function which creates HardLinks via cm_Link().
134 cm_Link() is a new vnodeops function which creates links
137 smb_ReceiveNTRename() does not support the File Copy and
138 Move Cluster Information operations described in its interface.
139 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
141 * When opening files via symlinks, we should follow the symlinks
142 until we reach the actual file stat cache entry. The stat cache
143 entry of the file should then be stored in the FID instead of
144 stat scache entry of the symlink.
146 * return bad operation errors for all unimplemented functions
147 even if we do not know the functions exist.
149 * Log bad packets and unknown operation packets to the trace log
151 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
154 * Update list of known CIFS operations to include all those listed
155 in CIFS-TR-1p00_FINAL.pdf.
157 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
158 to support the REG_EXPAND_SZ type.
161 * A new Windows authorization group "AFS Client Admins" is now
162 created and populated with the members of the "Administrators"
163 group. The group is used to determine which accounts on the
164 machine may be used to modify the AFS Client Configuration via
165 the UI and command line tools. afs_config.exe, fs.exe,
167 * Modify the WinLogon Logoff Event Handler to query NT4 domain
168 controllers for the remote profile path if Active Directory
169 services are not available.
171 * Fix aklog.exe to not add the AFS ID to the username
173 * PTS registration of new users to foreign cells has been added to
176 * The cm_Daemon thread is used to perform checks for
177 down servers, up servers, volumes, callback expirations,
178 lock maintenance and token expiration. Due to a gaff in
179 larger integer division the thread never performed any
180 work. Instead the current time computation would always
181 be less then the trigger times. This had an adverse affect
182 on the client's ability to maintain communication with servers,
183 keep volumes up to date, and flush user tokens and acls
184 when they have expired. This was broken when the 1.3 branch
185 was modified to support VC7 which no longer included
188 * An initialization problem with the Freelance code was
189 detected while fixing the callbackRequest. The cm_rootSCachep
190 object is obtained during afsd_InitDaemons() but the callback
191 information is incomplete. The callback information will not
192 be obtained until cm_MergeStatus is called from within
193 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
194 test for the conditions under which the callback information
197 * Reports have been filed indicating that callbacks were
198 being lost. An examination of the code indicated that the
199 cm_server_t objects were not being properly reference
200 counted by the cm_scache_t and cm_callbackRequest_t objects.
201 In particular, the cm_server_t objects may have been freed
202 from beneath the cm_conn_t objects.
204 All of the reference counting is now done via the functions:
209 this improves the ability to track the referrals.
211 Each cm_BeginCallbackGranting Call now allocates a reference
212 to the cm_server_t. The cm_EndCallbackGrantingCall either
213 frees the reference or transfers it to the cm_scache_t
214 cbServerp field. These are then appropriately tracked
215 through the cm_Analyze call.
217 * Ensure that the dnlc hash table is the same size as the
218 dir name hash table (as per original author's note).
219 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
220 for compatibility with 64-bit systems.
222 * fix smb_ApplyV3DirListPatches to properly apply the hidden
223 attribute to dotfiles when the infoLevel < 0x101 and
224 cm_SyncOp has failed.
226 * Fix the Freelance registry initialization code. There
227 was a possibility that some systems could end up with
228 garbage in the registry during a clean install.
231 * file and directory names beginning with "." will now be given the
232 hidden attribute when the volume access is anonymous. this matches
233 the behavior when the volume access is via an authenticated user.
235 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
236 key. When a change occurs mark the root.afs data as invalid and
237 for it to be reloaded on the next access. This allows administrators
238 to modify the mount point list without restarting the service.
240 The freelance client used to provide a fake modification time for
241 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
242 Added code to extract the last modification time of the Freelance
243 registry key and use that instead. The time now represents the
244 most recent mount point change.
246 * PTS registration of new users to foreign cells has been added to
249 * Additional Cache Control and Credential Manager options have been
250 added to the WiX installer. See deployment guide for details.
252 * The CachePath setting is now optionally a REG_EXPAND_SZ type
254 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
257 * The loopback installation code may have had a problem updating the
258 %ETC%\HOSTS file which could have resulted in a premature failure.
259 Work around code has been added for the case where the file cannot
262 * The default max chunksize was increased from 15 (32K) to 17 (128K)
263 because Windows sends 64K blocks when using overlapped writes.
265 * The default number of server threads was increased from 4 to 25 to
266 better handle overlapped writes.
268 * The "AfscredsShortcutParams" registry value was not being properly
269 loaded by afscreds.exe. Therefore, the default value was always being
270 used instead of the value set by the installer.
272 * Windows XP provides downgrade attack detection to prevent an attacker
273 from being able to force the use of NTLM simply by disrupting
274 communication with the KDC. This attack cannot exist between the
275 Windows CIFS client and the AFS Client Service. Therefore, when a
276 downgrade has been detected the afs pioctl library will force the
277 establishment of a new CIFS connection using NTLM.
279 * A locking error was discovered surrounding all references to volume
280 server lists within the cm_cell.c source file.
282 * The logged into Windows username was incorrect on Terminal Server
285 * A new registry value "NonPersistentCaching" was added to the service
286 parameters key. When set to a non-zero value, the afs cache is stored
287 in the Windows paging file. There are two limitations to choosing
289 1. when persistent caching is implemented it won't work with
290 this flag set since there will be nothing to persist.
291 2. with this flag set the initial paging allocation cannot be
292 changed while the service is running
294 * An initialization bug was discovered in aklog.exe which affected users
295 who have a domain name for their afs servers which could not be mapped
299 * afs_config.exe now validates cell names against DNS in addition
300 to the CellServDB file.
302 * In order to allow the freelance client to connect to a volume with ID
303 equal to 1 on the default cell we changed the fake root.afs volume ID
304 once again. This time we choose 0xFFFFFFFF. In addition, we change
305 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
306 It will now be impossible for a volume ID to match that of another
307 cell unless the client is connected to 0xFFFFFFFD cells. That should
308 be enough room for growth.
310 * Fix "fs mkmount" command to work with UNC paths and when
311 started from non-AFS drives. It is now possible to create a mount
312 point in the freelance fake root.afs volume with the command
314 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
318 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
319 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
321 * The algorithm used to re-attempt access to the servers associated with
322 a volume has been altered to properly address the case in which all
323 servers have been marked down. The previous algorithm did not reset
324 the server's down flags so the servers were never actually retried.
325 This caused a problem with active volumes if the network connectivity
326 was lost as could be the case with a network cable removal, wireless
327 drop, or laptop hibernation. With the fix volume access is restored
328 almost instantenously when network connectivity becomes available.
330 * Support for SMB/CIFS browsing has been added to the AFS Client Service
331 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
332 listing of AFS submounts and freelance mount points. Support for
333 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
334 significantly enhances the behavior of AFS volumes within the Explorer
335 Shell. For instance, "AFS" now shows up as server in the Explorer
336 with each submount or freelance mount point visible as a share.
337 The right click menu in each folder now works with full functionality
338 on a consistent basis.
340 * The network provider can be configured to have different behavior
341 depending on the domain that the user logs into. These settings are
342 only relevant when using integrated login. A domain refers to an
343 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
344 local machine (i.e. local account logins). The domain name that is
345 used for selecting the domain would be the domain that is passed into
346 the NPLogonNotify function of the network provider. (see registry.txt
349 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
350 "Authentication Cell" which may be used to specify a default
351 authentication cell for afscreds.exe which is different from
352 the default cell for the AFS Client Service daemon.
354 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
355 afslogon.dll moved to %WINDIR%\System32\.
356 New registry entries added to register the dll for Winlogon events.
358 The logoff event will now force a call to ktc_ForgetAllTokens()
359 using the context of the user being logged off as long as the
360 user's profile is not loaded from within AFS. If the profile
361 was loaded from AFS we can't release the tokens since the Logoff
362 event is triggered prior to the profile being written back to
363 the its source location. This is now performed in an XP SP2
366 * Windows XP SP2 Internet Connection Firewall interoperability
369 * The %WINDIR%\afsdsbmt.ini contains four sections:
370 Submounts, Drive Mappings, Active Maps and CSC Policies.
371 The Submounts and CSC policies are now stored in the registry under
372 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
373 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
374 The Drive Mappings and Active Maps are stored in the registry under
375 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
376 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
378 There is no automatic migration of this data as it would be impossible
379 to consistently migrate data to user profiles which may not be active
380 when the machine is updated.
382 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
383 fake root.afs volume. For the same reasons as for the cellservdb file,
384 this information should not be in %WINDIR%. This information is now
385 kept under the registry key
386 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
388 The data from the afs_freelance.ini file will be automatically
389 migrated to the registry on first execution of afsd_service.exe
391 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
392 troublesome for several reasons. One, it is confusing for those who
393 expect the file to be named "CellServDB" instead of "afsdcell.ini".
394 Two, this file is not a Windows Profile formatted file. Three,
395 applications should not be reading or writing to %WINDIR%. It causes
396 problems for Windows Terminal Server.
398 The new location of CellServDB will be the OpenAFS Client install
399 directory which is by default C:\Program Files\OpenAFS\Client and can
400 be determined by querying the registry for
401 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
403 The existing afsdcell.ini will be migrated by the NSIS installer.
404 The Wix installer must still be updated to do the same.
406 * Change NSIS installer to use DNS by default; to remove Integrated Logon
407 High Security mode; and to add Terminal Services compatibility registry
408 entries to allow the OpenAFS tools to find the afsdcell.ini and other
409 configuration files in %WINDIR%.
411 * Add support for authenticated SMB connections. This will remove
412 the need for high security mode in most situations. Both NTLM
413 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
414 only NTLM can be used even though Kerberos is now supported. The
415 reason is that it is not possible to construct a service principal
416 which is unique to each individual machine.
418 SMB Extended Auth does not work on XP SP2 unless one of two registry
419 modifications are made:
421 (1) To disable the check for matching host names on loopback connections
422 set this key. This does not require a reboot:
424 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
425 "DisableLoopbackCheck"=dword:00000001
427 (2) To add the AFS SMB/CIFS service name to an approved list. This
428 does require a reboot:
430 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
431 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
433 afsd_service.exe will automatically add the current Netbios Name
434 to the BackConnectionHostNames list and then temporarily disable
435 the loopback check for one cycle of startup/shutdown of the service.
436 We assume most folks do not start/stop without a reboot so this
437 will be adequate in most cases.
439 * Fix security hole in afslogon.dll which allowed passwords to be
440 sent in clear text to the KDC in a misformed principal name.
442 * Fix cm_GetCell() to properly handle expired dns entries
445 * If Freelance mode is active and the afs_freelance.ini
446 file does not exist, do not create an empty file.
447 Instead create a file containing ro and rw mountpoints
448 to the default cell using the standard conventions.
450 * Modify the Freelance support to handle the ability
451 to create rw mount points in the fake root.afs volume.
453 * Changed the RPC mechanism used for token setting from
454 named pipes to local. Use of named pipes can be restored
455 by setting the environment variable AFS_RPC_PROTSEQ to
458 Named pipes were required when a Windows 9x system was
459 using a NT system in gateway mode which is incompatible
460 with our use of local loopback adapters.
462 * In afscreds.exe, if a username of the form user@REALM is
463 specified and no password is specified, do not perform a
464 kinit operation. Only perform the aklog functionality.
466 * Add a new registry value which allows the number of processors
467 on which afsd_service.exe executes to be restricted. Valid
468 values are 1..numOfProcessors
470 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
474 * A second MSI based installer option is now available.
476 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
477 request tickets for user/instance@REALM instead of just user@REALM
479 * Modify the Power Management Notify routine to wait for the Hard Dead
480 timeout period instead of a fixed 19 seconds. With the longer timeout
481 periods Hibernation and Standby could never succeed when network
482 connectivity is not available.
484 * The following fs.exe commands are now restricted to Administrator:
485 - checkservers with a non-zero timer value
488 - sysname with a new sysname list
497 setting the default sysname for a machine should be done via the
498 registry and not via "fs sysname".
500 * NSIS installer adds options to install Debugging Symbols
501 and the Microsoft Loopback Adapter; the user is now also
502 given the ability to select the afscreds.exe startup options.
504 * Build system modified to generate symbols for FREE (aka RELEASE)
505 builds as well as CHECKED (aka DEBUG) builds
507 * Sites which have a volume ID of 0x20000001 assigned to their
508 root.cell volumes have been experiencing problems with accessing
509 the root.cell volume of their cell when Freelance mode has been
510 active. This was because 0x20000001 was assigned to the fake
511 root.afs volume created by freelance. The fake volume id is
512 now set to 0x00000001 to prevent conflicts.
514 * The timeout logic in the AFS Client Service has been wrong
515 for sometime. It is based on two different assumptions.
516 First, the SMB client timeout is a fix value as was the case
517 with OS/2 Lan Manager. This assumption is incorrect. The
518 SMB timeout in Windows is a dynamic value computed based upon
519 a fixed minimum timeout to which is added time based upon the
520 size of the request and the performance characteristics of
521 the connection. Second, it is the responsibility of the
522 SMB Server to enforce the timeout requirements of the client.
523 This is untrue. The SMB Server cannot be expected to know
524 the requirements of the client. More importantly, if the
525 SMB server uses the SMB client timeout as a value to restrict
526 its behavior as an RX client, the performance characteristics
527 of the local SMB session would be used to prematurely terminate
528 WAN connections with significantly different performance
531 The timeout logic has therefore been modified in the following
533 . the Lan Manager Workstation (SMB) Session Timeout is used only
534 as a basis for configuring the Connection Dead Timeout
535 and Hard Dead Timeout values. The Connection Dead Timeout
536 must be at least 15 seconds longer than the SMB Timeout
537 and the Hard Dead Timeout must be at least double the
538 Connection Dead Timeout.
539 . New registry entries have been added to allow the Connection
540 Dead Timeout and Hard Dead Timeout values independent of the
541 Lan Manager Workstation Session Timeout
542 . The test to enforce the SMB Client Timeout has been removed.
544 One of the side-effects of removing the enforcement of the SMB
545 Client Timeout is that regardless of whether or not the SMB client
546 is available to receive the response (and how would the SMB server
547 know) the RX protocol response can be used to update the AFS
548 Client Service state for ready access by future SMB client
551 This should be the end of the "Server paused or restarting messages"
553 * Add support for arbitrary UNC paths to the pioctl() support.
554 This enables the fs commands as well as the AFS Shell Extension
555 to work correctly when UNC paths are being used.
557 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
558 DNS if the cell configuration cannot be determined via CellServDB
560 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
561 are ever set more than once at a time
563 * Fix the management of lists of cm_cell_t structures when using
564 DNS to lookup cell information. The previous code would fail to
565 reuse the same cellID for a cell if DNS was used more than once
566 for a given cell name. When the ttl expired, a single cm_cell_t
567 could be inserted into the cm_allCellsp list more than once
568 producing a loop. In addition, the vlServerp list belonging to
569 the cell was not freed resulting in improper refCounting of the
572 * Add DNS support to cm_IoctlNewCell() which previous only examined
575 * Add cm_FreeServer() function and call it from cm_FreeServerList()
576 to properly garbage collect cm_server_t objects
578 * Add numVCs variable to smb.c to track the number of smb_vc_t
579 objects created and use it to initialize the vcID field which
580 previously was set to 0 in all objects resulting in FindByID
583 * Fixed DNS lookups to work consistently throughout the OpenAFS
584 product instead of just from within the afsd_service.exe
586 * Added a runtime check to ensure that AFS Client Service SMB
587 Server is accepting connections before attempting to mount
590 * Read IP addresses for volume servers out of the CellServDB
591 file if gethostbyname() on the hostname fails.
593 * Fix getcellconfig() to populate both the Hostnames as well
594 as IP addresses when loading cell data via DNS
596 * Increase the Connection Dead Time to 50 from 20 seconds
597 Increase the Hard Dead Time to 120 from 40 seconds
598 (matches the Unix values)
600 * Fixed an assertion validating the number of allocated NCBs
602 * Fixed the build environment to consistently build for
603 Windows 2000 and above. (APPVER = 5.0)
605 * Fixed rx_debug to properly validate the receipt in incoming
606 data with select() and recvfrom(). Do not copy data out of
607 the socket buffer unless success is indicated.
610 * afsd_service.exe will now display a message box to the
611 desktop when it terminates due to an IP Address Change.
613 * installer no longer deletes AFS Server configuration data
616 * installer generates a warning dialog if the RPC service
617 is not properly configured
619 * installer compressed with lzma instead of bzip2
621 * afsd_service.exe shutdown crash solved once and for all
623 * reference counting of smb_vc_t data structures improved
625 * name space collision of smb_fid_t event objects corrected
627 * the output of "fs memdump" is now written to
628 %WINDIR%\TEMP\afsd_alloc.log
630 * the file TaAfsApp_1033.dll is now properly installed allowing
631 the User Manager to start
633 * a new algorithm is used for computing filename pattern matches
635 * afscreds.exe now accepts user names containing instance
638 * Fix the Directory Name Lookup Cache to be case-sensitive.
639 This is crucial in environments in which a Windows client
640 is accessing a directory with more than one filename that
641 differs only by case. If the directory contains "FOO"
642 and "Foo". You want "DEL Foo" to delete the correct one.
643 We still have a problem in that "DEL foo" will delete a
644 random filename. This will be addressed in a future release.
646 * Fix afscreds.exe -M option (renewMaps) to work when High
647 Security mode is off. Also, remember to disable the ActiveMap
648 flag in afsdsbmt.ini when a drive mapping is removed.
650 * Updates to NSIS installer script. AFS Server configuration
651 data will not be destroyed on un-install or re-install.
652 Use a better compression algorithm.
654 * afslogon.dll now uses KFW to obtain tokens when available
656 * afslogon.dll when given an all uppercase username will
657 attempt to authenticate with both the uppercase name
658 and an all lowercase variation
660 * DST modification removed. The fix appears to make things
661 worse after a reboot of the machine.
663 * fs.exe: added "cscpolicy" which is used to
664 change client side caching policy for AFS shares
666 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
667 [-documents] [-disable] [-help]
669 * Several uninitialized variables have been initialized
671 * It is now possible to obtain tokens using cross realm
672 Kerberos within afscreds.exe:
674 user: jaltman@ATHENA.MIT.EDU
676 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
677 will will in turn be used to obtain afs@DEMENTIA.ORG.
678 The resulting token will be stored with the display name
679 jaltman@ATHENA.MIT.EDU@dementia.org
681 * aklog.exe has been added to the client
683 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
684 [[-p | -path] pathname]
688 -d gives debugging information.
689 krb_realm is the kerberos realm of a cell.
690 pathname is the name of a directory to which you wish to authenticate.
691 -noprdb means don't try to determine AFS ID.
692 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
693 (default is Kerberos V)
694 No commandline arguments means authenticate to the local cell.
697 * All of the resource files have been restructured to adhere to
698 a set of rules IBM implemented for loading string resources.
699 These rules had either been forgotten or were not discovered
700 by folks working on the OpenAFS sources. The end result was
701 memory corruption. This is primary item which was preventing
702 the AFS Server from working.
704 * Increased the size of the maximum ticket size stored in a token
705 from 344 bytes to 12,000. Increased the buffers used to convey
706 messages between the pioctl() caller and the SMB Server from
707 1000 bytes to 12,512. The code appeared to have been writing
708 above the top of the stack by quite a few number of bytes.
709 (The increased ticket size is necessary for the next item.)
711 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
712 Instead the raw Kerberos 5 ticket is used in its entirety. This
713 is extremely important as it allows us to use pure Kerberos 5 KDCs
714 as the source of the AFS authentication. The use of up to 12,000 byte
715 tickets will allow tickets produced by all versions of Microsoft
716 Active Directory to be used.
717 - create a user account.
718 - designate it DES only
720 - specify its UPN to be "afs@realm"
721 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
723 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
724 is special when using long file names. (you must use "*.*" and not "*")
725 Instead only enforce it when performing 8dot3 searches.
727 * Fixed the DST problem with creation times being set one hour ahead
729 * Fixed the problem when using \\afs\cell-alias. For example,
730 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
731 for the alias name; instead simply expand the name. One of the
732 symptoms of this problem was a loss of acquired tokens.
734 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
735 of strings. (Only English strings provided.)
737 * Fixed the installer to properly replace in use files.
739 * Fixed the build system to cleanup generated component version files
741 * The release build compiled with MSVC 6.0 compiler to avoid the
742 afsd_service.exe shutdown crash. This does not solve the problem
743 but simply avoids it for the time being.
747 * fix afslogon.dll to not corrupt memory when High Security mode
750 * fix afsd_service.exe to not attempt to restore the stack when
751 an exception occurs. (not safe in multi-threaded programs)
753 * fix uninstaller to properly remove the CRT and MFC DLLs
755 * remove a Message Box from afscreds.exe when getcellconfig()
756 fails on a kerberos realm which is not a cell
758 The following is a list of changes to the OpenAFS for Window client
761 * "fs setserverprefs" will leave afsd service deadlocked
763 * "vos listaddrs" will core dump
765 * installer sets the appropriate keys to support Integrated Logon
767 * installer disables the "Find Lana by Name" functionality as it
768 was causing headaches for many users
770 * fix the intermittent crash of the power management thread when
771 shutting down the AFS Client Service
773 * optimizes the obtain drive mount list functionality which is
774 executed every time the mount tab in afscreds.exe and afs_config.exe
775 are refreshed. (this happens a lot)
777 * fix the service shutdown logic. add the STOP_PENDING state
778 and do not accept additional service events after we declare
781 The following is a list of changes to the OpenAFS for Window client
784 * flexelint was run against the source tree and hundreds (perhaps
785 thousands) of corrections were applied to ensure prototypes
786 were in use; types were used consistently; variables were
787 initialized; unused variables were removed; etc.
789 * A wide variety of instrumentation was added including the
790 ability to produce a stack trace from within afsd_service.exe
793 * Dynamic configuration of the RDRtimeout value based upon the
794 LanMan Workstation Session Timeout
796 * The mount root no longer needs to be called "/afs". This
797 is now set by a registry value "MountRoot" within the key
798 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
800 * The cell list is now only read out of afsdcell.ini when the
801 file changes instead of each time a cell is resolved.
803 * Thread synchronization was added to cm_server.c and ktc_nt.c
805 * All calls to GlobalAlloc()/GlobalFree() were replaced with
806 calloc()/free(). The Global functions were needed on Windows 3.x
807 but have caused a variety of problems on the Win32 platforms.
808 Avoiding them is highly recommended by several Microsoft
809 Knowledgebase articles
811 * Support for Symbolic Links added to the AFS Shell Extension
813 * Added a registry value "OverlayEnabled" to determine if
814 Shell Extension Overlays should be enabled.
815 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
817 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
818 separate trees for checked and free builds. Build system supports
819 a custom directory src\WINNT\extra which can be used as a grafting
820 location of organization specific additions to the build tree.
822 * New installer built using NSIS 2.0.
824 * Named all kernel objects in order to allow them to be monitored
825 with tools such as SysInternals' ProcExp.exe.
827 * Introduced new EventLog framework for AFSD
829 * Introduced Power Management interface to AFSD for Standby and
830 Hibernate modes to allow cache to be flushed prior to network
833 * Utilize Win32 DNSQuery API instead of internal routines. This
834 allows DNS SRV queries to be sent to all current domain name
835 servers. Not just one specified in an INI file. DNS is now
838 * "NetbiosName" registry value may be used to specify a fixed
839 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
840 when the loopback adapter is in use. If you need to use the
841 old notation with a loopback adapter installed specify a registry
844 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
846 * Refactor all modules which depend on LAN Adapter and NetbiosName
847 determination in a new library: lanahelper.lib. This allows for
848 consistent behavior throughout the product.
850 * Move the afsd.log and afsd_init.log files to the directory specified
851 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
852 for services. Added the Date to the log entries.
854 * New registry value "RxMaxMTU" used to limit the size of the RX
855 packets sent by the AFS Client Service to the Server. In order
856 to enable OpenAFS to work across the Cisco IPSec VPN the packet
857 size must be restricted to 1264 or smaller. The latest NSIS
858 installer sets a value of 1260 by default.
860 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
861 packets. This is not needed in order to work across the Cisco
862 VPN but might be needed for other network environments. This
863 value is not set by the NSIS installer.
865 * New registry value "HideDotFiles" is used to apply the Hidden
866 attribute to files whose names begin with a '.'. This value
867 is set by the NSIS installer.
869 * New registry value "MaxMpxRequests" allows the maximum number
870 of multiplexed sessions to be configured at run time. This
871 value is not set by the NSIS installer. The default value is
874 * New registry value "MaxVCPerServer" allows the maxmimum number
875 of VCs per server to be configured at run time. This value is
876 not set by the NSIS installer. The default value is 100.
878 * New registry value "AllSubmount" allows the "all" submount to
879 be disabled by setting its value to 0x00.
881 * Allow cells names to be valid mount points
882 \\<netbiosName>\<cellname>
884 * Store the active state of drive mappings in order for afscreds.exe
885 to restore them upon startup
887 * Add exception handling to generate a Stack Trace to the afsd_init.log
888 file if one happens to occur.
890 * Add lots of logging to help detect the cause of invalid SMB packets
892 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
893 conversion of Kerberos 5 "afs" service tickets. Supports auto-
894 renewal of expiring tokens as long as afscreds.exe is running.
896 * New afscreds.exe command line options:
898 -M = renew drive maps
899 -N = ip address change detection
902 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
903 determines whether or not MIT Kerberos for Windows should be used
904 to obtain tokens via Kerberos 5 tickets.
906 * New registry value "AfscredsShortcutParams" in
907 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
908 determines the command line parameters to be specified when "fixing"
909 the AFS Shortcut in the user's startup folder.
911 * The "ShowTrayIcon" registry value has been moved from
912 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
913 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
915 * The <cell name> registry values used to store the token expiration
916 reminders have been moved from
917 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
918 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
920 * Obtain the Logon User Name from the Explorer key when available
922 * new text document doc\txt\winnotes\registry.txt lists all registry
923 values used by OpenAFS (excluding the AFS Server)
925 * BUG: rx_securityClass objects were not properly reference
926 counted and were never freed.
928 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
929 would be generated. The existence of a server does not imply
930 that it is not down. If all of the servers for a cell are down
931 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
934 * BUG: the directory name lookup cache failed to free the entries
935 in the cache when the name cache entries cycled. The entries
936 in the cache would become dereferenced without being freed.
938 * BUG: fs setserverprefs could be executed without Administrator
941 * BUG: the number of allocated NCB objects (100) exceeded the number
942 which could actually be waited upon by the kernel (64). Any objects
943 which were utilized above the limit could never have event completions
946 * BUG: smb_username_t objects were not being reference counted and
947 were not properly freed.
949 * BUG: smb_tid_t objects could under unusual circumstances be freed
950 before they were no longer referenced.
952 * BUG: smb_fid_t object pointer were frequently used even when
953 their value could be NULL. They were not properly released and
954 therefore they were never freed.
956 * BUG: smb_packet_t data structures were not completely initialized
959 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
960 Denied" because that causes the Explorer Shell to try again until
961 access is obtained. Instead return "Remote Resources" which allows
962 the shell to move on and treat the error as transient.
964 * BUG: when initializing the NCBreturns structure, separate Event objects
965 were created for each NCB although a single Event object was supposed
968 * BUG: smb_dirSearch_t objects were not being properly referenced counted
971 * BUG: smb_tran2Packet_t objects were not being properly referenced
974 * BUG: directory path creation did not handle the case of multiple
975 directories requiring creation in one attempt
977 * BUG: SMB requests which required an Extended Response were ignored.
978 This prevented some files from being written to AFS volumes.
980 * BUG: character strings were being freed even after they were
981 inserted into in use data structures
983 * BUG: inconsistent usernames were used when High Security mode was
984 enabled. (there is still much to do in this area)
986 * BUG: pioctl() calls which require out of band RPC operations were
987 susceptible to race conditions when performed by multiple processes
989 * BUG: memory allocation and deallocation crossed instances of the
990 C Runtime Library producing memory leakage and corruption in
991 afscreds and the client configurator.
