1 Since 1.4.0 rc4: 1.4.0 rc5 released (25 Sep 2005)
3 * New Product Code GUIDs issues for 1.4 and 1.5 branches. Separate
4 GUIDs for each platform.
6 * Documentation directory structure and default installation rules
9 * New OpenAFS for Windows HTML Release Notes installed
10 as part of the documentation set.
12 * Add thread id to rx debugging messages
14 * When all servers are offline, return a bad network path error
15 immediately. This is necessary to allow Explorer to do the
16 right thing and not hang. The background daemon thread will
17 check the down servers every 30 seconds to see if they are
20 Since 1.4.0 rc3: 1.4.0 rc4 released (14 Sep 2005)
22 * The AFSCache file has been modified to store both the
23 serial number of the volume on which the file resides
24 and the SID of the local machine. If either change,
25 a new UUID is generated.
27 * add "fs flushall" command that forces all data buffers
30 Since 1.4.0 rc2: 1.4.0 rc3 released (4 Sep 2005)
32 * add support for '/' instead of '\' in pioctl() calls
34 * Apply AFS Client Admins group protect to AFS Shell Extension
36 * Add support for \\afs\<name> to most AFS Shell Extension
37 commands except the symlink methods.
39 * when installing the Microsoft Loopback Adapter, enable
40 MS Client for Networks and prevent an install failure
41 by not calling CoInitialize twice in the same thread.
43 * reload cell vldb values from the CellServDB every two
44 hours in case it changes
46 * When updating cell information from DNS, be sure to set
49 * Add support to allow use of \\AFS\<foo> where <foo> is
50 either a mount point or symlink. As <foo> is normally
51 treated as a share name, we transform it into \\AFS\all\<foo>
54 * Init 'code' to prevent false errors when integrated logon
55 is disabled and the service is not running
57 Since 1.4.0 rc1: 1.4.0 rc2 released (28 Aug 2005)
59 * Removed trace log messages that were hampering performance.
61 * Fixed a deadlock that was being triggered by editing Word
62 documents stored within AFS with WinWord 2003.
64 * Bit 3 of the TraceOption registry value is now used to set the
65 default for "fs trace" in the non-Debug builds. The new default
66 is off for release builds and on for debug builds.
68 * Bit 2 of the TraceOption registry value can be used to turn on
69 real-time output of debug log entries to the Windows Debug
70 Output monitor interface. This data can be viewed with tools
71 such as Sysinternal's DbgView.
73 New development series 1.5.0 begun (17 Aug 2005)
75 Since 1.3.87: 1.4.0 rc1 released (17 Aug 2005)
76 * Byte-range locking as described in cm_vnodeops.c has been implemented.
78 * When the cache manager reports ALLBUSY or ALLOFFLINE for
79 a resource we should not be returning status codes such
80 as Network Busy or Remote Host Down because these errors
81 will imply that the AFS Client Service is Busy or Down
82 and that is simply not the case. Instead we will return
83 Bad Network Path as the path is temporarily not available.
85 Instead of returning Sharing Paused when there is a
86 timeout error, return Timeout. Once again, the AFS Client
87 Service is not paused.
89 * afscreds.exe would display an Obtain Creds dialog when
90 the expired credentials reminder was triggered even
91 if there was no network path to the KDC. This is prevented
92 by adding KDC probe logic to the reminder thread.
94 * afscreds.exe would display expired tokens no differently
95 than unexpired ones. This would make it difficult for the
96 user to distiguish when the tokens were expired. For the
97 English build added a new resource string "(expired) that
98 is displayed instead of the expiration time.
101 * "fs wscell" when executed in freelance mode will return the
102 name of the cell configured in the registry. The root.afs
103 volume is not loaded from this cell, but it is used for the
104 default for aklog and integrated login.
106 * "fs mkmount, fs rmmount, symlink make, symlink remove" will
107 no longer work on \\AFS\all when freelance is being used
108 unless the user is a member of the "AFS Client Admins" Windows
111 * some more checks performed during persistent cache validation.
114 * Optimize calls to cm_CheckServer from cm_Analyze. Only check
115 down servers for the current cell not all cells.
117 * If the scache LRU list becomes corrupted, the AFS Client Service
118 might enter an infinite loop at startup. Detect the corruption
119 and discard the cache contents in this case.
121 * Fixed the Explorer Shell's remove mountpoint functionality.
123 * Fixed a deadlock caused by the holder of cm_aclLock attempting to
124 obtain a mutex lock on a cm_scache_t object whose lock is held by
125 a thread attempting to obtain the cm_aclLock.
128 * Really fixed DNS AFSDB queries to ensure that "csail" cannot be
129 misinterpretted as "csail.mit.edu" when the resolver
130 is configured to append ".mit.edu" to failed DNS queries.
132 * Added a new registry key, "LogoffPreserveTokens" (see registry.txt),
133 that can be used to force the preservation of user tokens upon logout.
135 * Update the NSIS install scripts to use NSIS 2.07. This release adds
136 recommended installation categories: AFS Client, AFS Administrator,
137 AFS Server, AFS Development Kit. Each category includes a different
138 default subset of the OpenAFS components.
140 The OpenAFS logo is now associated with the NSIS uninstall entry
141 in the Add/Remove Programs control panel.
143 * The user name associated with AFS tokens when obtained with
144 integrated login, the afs systray tool, or aklog will always
145 include the full Kerberos 5 user principal name regardless of
146 whether or not the cell is local to the realm.
148 * Eric William's IFS redirector has been checked onto the CVS head.
149 This code is experimental at the current time and is not being
150 incorporated into the 1-4 branch releases. Instructions for
151 building from sources are found in the top-level README-NT file.
153 * Modify integrated login so that it does not enter an infinite
154 loop if the service is not set to auto start.
156 * Added asetkey.exe used to set a Kerberos 5 key for use by the
159 * Added uninstall.exe to Wix installation
161 * More modifications to algorithms used to wake sleeping threads.
165 * Changes to the algorithms used to wake threads when they are
166 put to sleep because of conflicts over buffer operations.
169 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
170 the process of producing AFS tokens. The tokens are stored within
171 the AFS Client Service but the Kerberos 5 tickets have been discarded.
172 New functionality has been added to temporarily copy the tickets to
173 a file ccache during the short window between the NPLogonNotify and
174 WinLogon Logon Event. The Logon Event handler starts a process as
175 user, afscpcc.exe, that copies the tickets into the default ccache.
176 The file ccache is then destroyed by the event handler.
178 * During synchronization operations on stat cache entries, if threads
179 are forced to sleep it was possible that the threads would not be
180 woken under heavy load.
182 * Enforce the delete on close flag specified by the NTCreateX()
185 * A race condition in the rx library was fixed that resulted in
186 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
187 was cleared when threads were still waiting to use the
188 connection. Also, fixed a potential case in which the
189 connection could be destroyed while threads were waiting to use it.
191 * The DNLC freelist has been seen to become corrupted with still
192 active entries being stored on the freelist. Changes were made
193 to perform a better job of cleaning entries before placing them
194 onto the freelist; marking them with the correct magic value when
195 purging the list; and allowing the list to be purged on startup
196 if the cache validation fails.
198 * Windows Crash Reporting does not get triggered for afsd_service.exe
199 because it provides its own top level exception handler. This patch
200 places an explicit call to ReportCrash() on platforms which support
203 If you configure Crash Reporting via AD Policy to capture crash
204 reports within the domain, then you will receive this output.
206 * Generate MiniDumps independent of the Windows Crash Reporting.
208 (a) If an exception occurs,a minidump will be generated at the path
209 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
210 can be set to any other type via use of the
213 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
215 (b) MiniDumps can be generated at any time using the "fs minidump"
216 command. This allows you to generate a minidump without
217 stopping the process or even requiring the use of a debugger
220 * an RX connection which reports bad ticket now treats it the same way
221 the expired ticket is treated. The ticket is removed from the
222 connection and a new anonymous connection is established.
224 * fs memdump now requires that the caller be in the AFS Client Admins
227 * additional debugging information is provided in cm_Analyze when the
228 error code is ignored.
230 * Fix a regression introduced into the pioctl() client code which
231 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
232 MIT KFW is not installed. (1.3.82a)
234 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
237 * Fix a race condition in cm_EndCallbackGrantingCall() that
238 could leave 'nrevp' pointing to freed memory. In the process,
239 optimize the processing to ensure that the applications monitoring
240 the status of the stat cache entry are only notified at most
243 * Conditionalize access to the Explorer Shell AFS->Mount Point
244 ->Remove menu item. Disable the item if the selected item(s)
245 are not mount points.
247 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
248 Local Storage. This eliminates thread contention on the
249 global RX free packet queue. This should improve performance
250 on multi-CPU systems.
252 * Fix the IP address filtering code to properly load/unload
253 the IPHelper DLL so that Windows XP/2003 and beyond systems
254 do not have to manually probe the registry.
256 * CleanupACLEnt() was not being called consistently with
257 the cm_scache_t object referred to by the back pointer
258 mutex locked. This could in very rare conditions lead to
259 an invalid memory access.
261 * Added a script command to the msi installer "afs_replace"
262 which can be used to replace one version of OpenAFS with
263 another without requiring an uninstall and reinstall if
264 the installed msi is no longer in its original location.
266 * Apparently the problem with multi-domain forests with cross-
267 realm trusts to non-Windows realms was not entirely solved.
268 The authentication to the AFS SMB service failed because
269 the wrong name was being used. Using ASU as an example,
270 the authentication was being performed with the name
271 "QAAD\user" (an account in the forest root) and not
272 "user@ASU.EDU (the MIT Kerberos principal used to login with)
274 The solution was to add an additional dependency on KFW
275 in order or to be able to easily obtain the client principal
276 name stored in the MSLSA ccache TGT. This information is
277 used in two locations:
279 - the pioctl() function
281 - a new WinLogon Event Handler for the "logon" event.
283 The pioctl function will now be able to use the correct
284 name when calling WNetAddConnection2() and the "logon"
285 event handler will now be able to call WNetAddConnection2().
286 The hope is that the "logon" event handler will be called
287 before the profile is loaded but I have not guarrantee
291 * Fixed a locking error in cm_TryBulkStat() which had the
292 potential of deadlocking the system for the length of time
293 it takes to perform a bulk status fetch operation.
295 * Replaced time conversion code (UnixTime <-> FILETIME) to
296 be completely arithmetic instead of relying on a bizarre
297 algorithm involving a variety of C RTL time functions.
298 This has the side effect that UnixTime and FILETIME which
299 are both stored in UTC are interpretted as UTC throughout
300 the year. Windows will apply the same localization to AFS
301 as it does to NTFS. Applications which rely on the ability
302 to sync files between the two file systems will no longer
303 see the timestamps of files in AFS change an hour relative
304 to the files stored in NTFS or Windows based backup devices.
306 * Fixed a invalid memory access under a bizarre circumstance.
307 Windows will allow a physical mass media device to be
308 installed via Plug N Play to the system and will assign it
309 the lowest available drive letter. This is true even if the
310 drive letter is currently assigned in the user session to
311 a network device via NET USE (or its equivalent.) When this
312 happens, queries sent to the CIFS server will contain invalid
313 data. This invalid data was not being caught by the AFS
314 Client Service and was resulting in a crash when Freelance
317 * Fixed a reference count error when registering callbacks
318 on a stat cache object if the callback was already registered
320 * Add a case to cm_Analyze() in order to handle the case where
321 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
322 the server list for the volume is empty. In this case, force
323 an update of the volume info and retry.
325 * Insert a missing cm_EndCallbackGrantingCall() which could
326 result in threads waiting for a callback to complete to never
329 * In the persistent cache, there is a maximum number of volume
330 entries. Allow volume entries to be reused if the maximum
331 number have been allocated and their reference count is zero.
333 * If we already have a dead virtual connection object, don't
334 ignore the fact that additional dead vc objects must be taken
337 * Removed a deadlock condition introduced in the summer of 2004.
338 Do not hold mx locks around calls to RX functions including
339 rx_NewCall(). That is what reference counts on the rx_connection
342 * Fixed an initialization error in afslogon.dll which could
343 result in random behavior including a failure to terminate
344 the NPLogon function. (1.3.80b)
346 * Fixed an error preventing the use of SMB authentication
347 on Windows 2000. (1.3.80a)
350 * Updated CellServDB to Public CellServDB 16 Mar 2005
352 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
353 misinterpretted as "csail.mit.edu" when the resolver
354 is configured to append ".mit.edu" to failed DNS queries.
356 * Fixed another case in which the client would replace connections
357 to the host when it was not necessary. In this case the
358 situation would occur if cryptall was on and the connections
359 were unauthenticated due to lack of an appropriate token.
361 * OpenAFS for Windows has failed to work at sites which are
362 utilizing a cross-realm trust between an MIT/Heimdal realm
363 and a multi-domain Windows forest when the workstation being
364 accessed is not located in the root domain. This is caused
365 by a bug in the workstation which was triggered after the
366 introduction of Windows 2003 Server. When the bug is triggered,
367 the workstation attempts to authenticate users to afsd_service.exe
368 by contacting the Domain Controller instead of using the
369 LSA loopback authentication mechanism.
371 One of the reasons this bug occurs is because the workstation
372 does not have a reliable way of knowing that the service whose
373 netbios name is "AFS" is located on the workstation. This will
374 be fixed starting in Longhorn Beta 1 by Microsoft. The
375 "BackConnectionHostNames" registry value will be used to
376 indicate that the authentications to that service name should
377 be performed using the loopback authentication mechanism.
379 In the meantime, when Logon Caching is enabled, we can force
380 afsd_service.exe to authenticate using the logon cache before
381 contacting the Domain Controller. This will work with both
382 password and smart card based logons.
384 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
385 flag should not be cleared if a volume's server reference is
386 marked as "offline". In the case where all of the volume's
387 servers are either "down" or the volumes are "offline", we want
388 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
389 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
390 should never occur in practice.
392 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
393 5 seconds, clear the server down and volume busy flags, and
394 then force an update from the VLDB. This allows the client to
395 update the location of a volume if the reason for it being
396 marked offline is because it is being moved. Calls to
397 cm_ConnByMServers() will be retried either until success or
398 the RDRtimeout period is reached.
400 * Correct the Power Management code behavior in response to
401 Standby, Suspend, and Shutdown events. Instead of flushing the
402 buffers associated with the mounted SMB submounts, simply write
403 all buffers which are marked dirty.
405 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
406 provides a list of cells other than the default cell for which
407 tokens should be obtained using the default Kerberos principal.
408 This functionality is logon domain specific and is only available
409 when using KFW for authentication.
411 * Fixed FindNext Invalid Handle error caused by over agressive
412 attempts at garbage collecting dirSearch entries when the
413 dirSearch ID wraps from the maximum value to 1.
415 * Add support for registry defined server preferences for VLDB and
416 File servers. See registry.txt for details.
418 * Increased default cache size to 96MB and default number of cache
421 * Fixed refCount leaks related to directory lookups and pioctl calls.
423 * Callbacks revoked during a race condition with an attempt to
424 obtain the same callback no longer result in an inaccessible
427 * New command line tool:
429 afsdacl : Set or reset the DACL to allow starting or stopping
430 the afsd service by any ordinary user.
432 Usage : afsdacl [-set | -reset] [-show]
434 -reset : Reset the DACL
435 -show : Show current DACL (SDSF)
437 * IP addresses are no longer queried once at startup. Instead IP
438 addresses are obtained as needed. Loopback adapter addresses are
439 no longer published to the server.
441 * Pay attention to the MIT KFW registry configuration for automatic
442 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
444 * Fix (once again) case-sensitive comparisons which was apparently
447 * Activate support for vos listvol -format
449 * Population of the "AFS Client Admins" group failed on non-English
450 versions of Windows because the name of the "Administrators" group
451 is localized. Now we lookup the name of the group by using the
452 Administrators Group Alias Relative ID.
454 * Multiple cell token acquisition within afscreds.exe was broken in the
455 case of Kerberos 5 cross realm authentication. Instead of contacting
456 the KDC associated with the cell's realm, afscreds would obtain a
457 token from the KDC of the user's realm. This would result in
458 "invalid kvno errors" while authenticating to the AFS servers.
459 Unauthenticated access would work. The symptoms would vary based upon
460 whether or not the VLDB servers had been contacted using unauthenticated
461 connections prior to the user obtaining tokens.
463 * The list of ACL entries was becoming corrupted. It appears as if
464 an ACL when it expires was not being appropriately cleaned up. In
465 fact, it was left in the list of ACLs associated with the scache
468 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
469 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
470 and "amd64_win64" for amd 64-bit processors.
472 * When executing executables, Windows provides a mechanisms by which
473 the normal search for DLLs can be bypassed. If a file foo.exe is
474 being executed and there exists a file or directory "foo.exe.local"
475 (the contents are ignored if a file), then Windows will search for
476 DLLs first in the "foo.exe.local" directory and second in the
477 directory in which the "foo.exe" file is located.
479 Previous releases of OAFW would improperly return
480 STATUS_NOT_A_DIRECTORY instead of the expected
481 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
482 to terminate the search for the DLL causing the execution of the
485 * Rework the reference counting of smb_vc_t objects. The references
486 stored in the waiting locks were not counted. This could result in
487 an assertion if the reference count drops to zero.
489 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
490 when running in freelance mode.
492 * Added support for persistent caching of file contents, stat entries,
493 volume data, cell data, and name lookup data. When the registry
494 value, "NonPersistentCaching", is not defined or set to 0 the file
495 specified by "CachePath" becomes a persistent cache file. The
496 size of the cache file is computed at run time. It has a maximum
497 size of approximately 1.2GB. The contents of the file will be
498 validated according to the rules specified by the "ValidateCache"
501 * Added support for UUIDs. UUIDs are kept for as long as the
502 cache file is intact.
504 * Added cmdebug.exe and support cache manager debugging callback
505 interfaces in afsd_service.exe.
507 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
508 [-addrs] [-cache] [-help]
509 Where: -long print all info
510 -addrs print only host interfaces
511 -cache print only cache configuration
513 * Symlinks to \\AFS\[all\]... will now be treated the same as
514 symlinks to /afs/.... However, please use /afs/... as otherwise
515 the symlinks won't work on Unix.
517 * Correct a problem with local CellID allocation for cells whose
518 server list is obtained via DNS instead of a CellServDB file. If
519 the DNS information expires the CellID assigned to the entry will
520 be changed. This causes all of the cm_scache_t objects which refer
521 to the old cellID number to become useless. Attempts to access
522 files or directories with cm_scache_t objects using the old cellID
523 will fail since the server list cannot be obtained.
525 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
526 be triggered if the volume referenced by the cm_scache_t object is
529 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
530 in addition to SERVICE_ACCEPT_STOP.
532 * Move RPC shutdown until after the SMB and RX shutdown procedures
533 complete. Block until RPC shutdown is complete.
535 * Modify afslogon.dll (integrated logon) to wait for service if its
536 state is START_PENDING. If the timeout period occurs, reset to
537 the retry interval and not the sleep interval.
539 * When renewing the server list for a cell obtained via DNS AFSDB
540 records, the cm_cell_t entry must be removed from the list of all
541 cells. Otherwise, the list of cells will be corrupted.
543 * In the dcache and scache modules, use the cm_scache_t dataVersion
544 instead of the cm_fakeDirVersion.
546 * Synchronize fs.c with the unix version.
548 * The variable used to determine whether a file or virtual memory
549 mapped cache is used was not properly initialized to a default
550 value. If the registry setting "NonPersistentCaching" was not
551 set, the choice would be random. Properly initialized to be
554 * The memory mapped view was never unmapped before closing the file
555 at service shutdown. This is now properly cleaned up.
557 * Default location of Cache file is now %TEMP%\AFSCache
561 * A bug affecting new installations of 1.3.75/76 would result in
562 the creating of incorrect mountpoints in the freelance root.afs
563 volume for the default cell.
565 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
566 of "root.cell", you have been affected by the bug. To correct the
567 problem, execute the following commands:
569 fs rmmount \\afs\all\<cellname>
570 fs rmmount \\afs\all\.<cellname>
572 fs mkmount \\afs\all\<cellname> root.cell <cellname>
573 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
577 * A bug has been fixed in the auto-generation of Freelance root.afs
578 symlinks which produced random entries in the \\AFS\all directory.
580 * Support has been added for multi-homed servers
583 * Added a new registry value, "StoreAnsiFilenames", which can be used
584 to force the use of ANSI character sets instead of OEM Code Pages.
585 This feature is useful when users require the ability to create
586 filenames with 8-bit characters and need to access the files from
587 both Latin-1 based Unix systems as well as from Windows.
589 Activation of this feature will prevent access to files stored with
590 8-bit OEM characters.
592 * Shutdown all SMB threads in a synchronized manner when stopping the
595 * There is currently a maximum cache size of 1.3GB. The limit is imposed
596 by the largest contiguous block of unused memory within the 2GB process
597 space which can be assigned to the memory mapped file. Unfortunately,
598 when the executable digital signature verification code is activated
599 Windows sees fit to further segment the process memory which in turn
600 reduces the size of the maximum cache file to less then 800MB. If
601 larger cache sizes are desired, a new registry value should be set:
603 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
605 Setting this value will disable the runtime verification of digital
606 signatures on afsd_service.exe and the afs dlls which it loads. It
607 will not disable the the version number check on those same files.
608 The signature verification is not a security messure and is only meant
609 to enhance the ability to afsd_service.exe to detect potential
610 destablizing mixtures of DLLs from incompatible distributions.
612 Added code to auto-disable the signature verification check if
613 the desired cache size is greater then 700MB.
615 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
616 used to verify the validity of the afsd_service.exe binary
617 as well as each of the AFS DLLs loaded by the service. Not only
618 must the digital signature be valid but the signatures of the
619 DLL must be signed by the same entity as the service.
621 * Implement new functions: cm_freelanceMountPointExists and
622 cm_freelanceSymlinkExists. Use them along with other validity
623 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
624 ensure that name collisions do not occur and that empty strings
625 are not valid file names.
627 A symlink may not have a name which would resolve to a valid
628 cell name. Doing so would prevent access to the cell.
630 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
631 re-initialization code. The reference counts of the fake root.afs
632 volume scache object(s) would become invalid when the mount point
633 or symlink lists were altered.
635 * Add registry entries to provide mappings from the afsdsbmt.ini
636 to the new locations for applications which count on the use
637 of the old Profile file APIs. These apps are likely to fail
638 if the user does not have administrator privileges and the
639 registry is locked down.
641 * The afs_config.exe submounts dialog had two errors.
642 First, attempts to remove entries failed because the registry
643 key was being opened without KEY_WRITE privileges.
644 Second, when editing a submount entry, changing the name
645 would add a new key and leave the original one in place.
646 Now the original submount will be removed if its name is
649 * In recent months there have been several incidents in which
650 users have experienced problems starting or accessing
651 afsd_service.exe and after significant effort has been spent
652 it has turned out that they have two versions of AFS on the
653 machine or an inconsistent set of DLLs.
655 Code has now been added to afsd_service.exe which will walk
656 the list of modules loaded by afsd_service.exe and validate
657 that the version of the AFS DLLs matches the version of the
658 afsd_service.exe executable. If they do not match the service
661 * When Freelance mode is enabled and there is no registry
662 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
663 will attempt to import the afs_freelance.ini file contents.
664 If the file does not exist, it was creating a dummy file
665 with a r/o and r/w entry for the default cell and then
666 importing those values.
668 This process has been changed. The temporary file is no
669 longer created. Also, both the OpenAFS Client install
670 directory as well as %WINDIR% are checked for previous
671 afs_freelance.ini files.
673 * Added support for VL_GetEntryByNameN(). Still need to add
674 support for VL_GetEntryByNameU() for multi-homed support.
676 * Fix a deadlock situation in afscreds.exe when canceling an
677 auto-generated Obtain Tokens dialog
680 * Fix the locking of objects during Directory Searches in the
681 SMB/CIFS server. The failure to properly lock the reference
682 counts was resulting in the premature freeing of smb_dirSearch_t
683 objects while they were still in use by the SMB/CIFS client.
684 This does not solve the "Invalid Handle" problem.
686 * Fix Find Cell By Name pioctl call to return a valid cell
687 name for the Freelance fake root.afs volume.
688 "Freelance.Local.Root".
690 * Fix the Explorer Shell Extension Symlinks->Add operation.
691 The dialog template was missing and the link destination
692 string was too short.
694 * Add support for symlinks to Freelance root.afs volume
695 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
696 <number> = "<linkname>:<relative-path>."
697 Use symlink.exe to create, list, or remove
699 * Remove the fallback to the use of KFW's KRB4 library when obtaining
700 tokens. We never obtain KRB4 tickets.
702 * Fix AFS Client Configuration Control Panel to support new SysName
705 * Fix a bug in afsd_service.exe which could result in the SysName
706 not being read from the registry.
709 * Add code to block the issuance of AFS tokens by aklog.exe or
710 afscreds.exe when the Kerberos 5 principal name contains a dot.
712 * Modify the IsAdmin() function to always treat the local SYSTEM
713 account as an AFS client administrator. Affects fs.exe and
716 * Modify the internal handling of Quota Exceeded errors
718 * Upgrade all reference count fields in the Windows cache manager
719 and the osi library to use unsigned long instead of signed short.
720 A similar fix has been applied to the afs rpc (rx) library.
722 * fix the Windows cache manager to prevent it from replacing the
723 rx_connection object associated with the cm_conn_t object on each
724 and every operation if "fs crypt" was set. This explains the
725 dramatic performance difference when crypt is used vs clear.
726 The problem: 'cryptall', a boolean flag indicating whether or not
727 "fs crypt" is set, was being compared to the rx_connection
728 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
729 1 != 2 and therefore the rx_connection was always destroyed
730 and replaced on each and every operation.
732 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
733 It is not safe for the cm_conn_t object to not be locked because
734 rx_DestroyConnection might be called from another thread if:
735 - the user's tokens have changed or expired
736 - the crypt mode has changed
738 This fix appears to have also taken care of the problems associated
739 with Overlapped Writes resulting in Delayed Write errors.
741 * fix NSIS installer's AdminGroup.exe to properly create and
742 remove groups when given -create or -remove. The string comparison
745 * fs sysname now accepts a list of sysname values
747 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
748 DWORD which when set to a non-zero value will cause error message
749 text to be output to stderr from the pioctl() routine. Useful in
750 debugging failures of fs.exe, tokens.exe, etc.
752 * added a test to the power management code to only perform a
753 flush operation if there is at least one network adapter which
754 is not a loopback adapter.
756 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
757 "EnableKFW". This value will not be read if the key
758 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
759 value under that key does not.
761 * provide mechanisms to force the use of krb524d for Kerberos 5
762 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
763 there is a new registry value "Use524" and for aklog.exe a new
764 command line parameter "-m".
766 * Fix the pattern matching algorithm to properly match patterns
769 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
770 which is used by both the original function and the new
771 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
772 creation of HardLinks in addition to Renaming. smb_Link()
773 is a new function which creates HardLinks via cm_Link().
774 cm_Link() is a new vnodeops function which creates links
777 smb_ReceiveNTRename() does not support the File Copy and
778 Move Cluster Information operations described in its interface.
779 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
781 * When opening files via symlinks, we should follow the symlinks
782 until we reach the actual file stat cache entry. The stat cache
783 entry of the file should then be stored in the FID instead of
784 stat scache entry of the symlink.
786 * return bad operation errors for all unimplemented functions
787 even if we do not know the functions exist.
789 * Log bad packets and unknown operation packets to the trace log
791 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
794 * Update list of known CIFS operations to include all those listed
795 in CIFS-TR-1p00_FINAL.pdf.
797 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
798 to support the REG_EXPAND_SZ type.
801 * A new Windows authorization group "AFS Client Admins" is now
802 created and populated with the members of the "Administrators"
803 group. The group is used to determine which accounts on the
804 machine may be used to modify the AFS Client Configuration via
805 the UI and command line tools. afs_config.exe, fs.exe,
807 * Modify the WinLogon Logoff Event Handler to query NT4 domain
808 controllers for the remote profile path if Active Directory
809 services are not available.
811 * Fix aklog.exe to not add the AFS ID to the username
813 * PTS registration of new users to foreign cells has been added to
816 * The cm_Daemon thread is used to perform checks for
817 down servers, up servers, volumes, callback expirations,
818 lock maintenance and token expiration. Due to a gaff in
819 larger integer division the thread never performed any
820 work. Instead the current time computation would always
821 be less then the trigger times. This had an adverse affect
822 on the client's ability to maintain communication with servers,
823 keep volumes up to date, and flush user tokens and acls
824 when they have expired. This was broken when the 1.3 branch
825 was modified to support VC7 which no longer included
828 * An initialization problem with the Freelance code was
829 detected while fixing the callbackRequest. The cm_rootSCachep
830 object is obtained during afsd_InitDaemons() but the callback
831 information is incomplete. The callback information will not
832 be obtained until cm_MergeStatus is called from within
833 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
834 test for the conditions under which the callback information
837 * Reports have been filed indicating that callbacks were
838 being lost. An examination of the code indicated that the
839 cm_server_t objects were not being properly reference
840 counted by the cm_scache_t and cm_callbackRequest_t objects.
841 In particular, the cm_server_t objects may have been freed
842 from beneath the cm_conn_t objects.
844 All of the reference counting is now done via the functions:
849 this improves the ability to track the referrals.
851 Each cm_BeginCallbackGranting Call now allocates a reference
852 to the cm_server_t. The cm_EndCallbackGrantingCall either
853 frees the reference or transfers it to the cm_scache_t
854 cbServerp field. These are then appropriately tracked
855 through the cm_Analyze call.
857 * Ensure that the dnlc hash table is the same size as the
858 dir name hash table (as per original author's note).
859 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
860 for compatibility with 64-bit systems.
862 * fix smb_ApplyV3DirListPatches to properly apply the hidden
863 attribute to dotfiles when the infoLevel < 0x101 and
864 cm_SyncOp has failed.
866 * Fix the Freelance registry initialization code. There
867 was a possibility that some systems could end up with
868 garbage in the registry during a clean install.
871 * file and directory names beginning with "." will now be given the
872 hidden attribute when the volume access is anonymous. this matches
873 the behavior when the volume access is via an authenticated user.
875 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
876 key. When a change occurs mark the root.afs data as invalid and
877 for it to be reloaded on the next access. This allows administrators
878 to modify the mount point list without restarting the service.
880 The freelance client used to provide a fake modification time for
881 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
882 Added code to extract the last modification time of the Freelance
883 registry key and use that instead. The time now represents the
884 most recent mount point change.
886 * PTS registration of new users to foreign cells has been added to
889 * Additional Cache Control and Credential Manager options have been
890 added to the WiX installer. See deployment guide for details.
892 * The CachePath setting is now optionally a REG_EXPAND_SZ type
894 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
897 * The loopback installation code may have had a problem updating the
898 %ETC%\HOSTS file which could have resulted in a premature failure.
899 Work around code has been added for the case where the file cannot
902 * The default max chunksize was increased from 15 (32K) to 17 (128K)
903 because Windows sends 64K blocks when using overlapped writes.
905 * The default number of server threads was increased from 4 to 25 to
906 better handle overlapped writes.
908 * The "AfscredsShortcutParams" registry value was not being properly
909 loaded by afscreds.exe. Therefore, the default value was always being
910 used instead of the value set by the installer.
912 * Windows XP provides downgrade attack detection to prevent an attacker
913 from being able to force the use of NTLM simply by disrupting
914 communication with the KDC. This attack cannot exist between the
915 Windows CIFS client and the AFS Client Service. Therefore, when a
916 downgrade has been detected the afs pioctl library will force the
917 establishment of a new CIFS connection using NTLM.
919 * A locking error was discovered surrounding all references to volume
920 server lists within the cm_cell.c source file.
922 * The logged into Windows username was incorrect on Terminal Server
925 * A new registry value "NonPersistentCaching" was added to the service
926 parameters key. When set to a non-zero value, the afs cache is stored
927 in the Windows paging file. There are two limitations to choosing
929 1. when persistent caching is implemented it won't work with
930 this flag set since there will be nothing to persist.
931 2. with this flag set the initial paging allocation cannot be
932 changed while the service is running
934 * An initialization bug was discovered in aklog.exe which affected users
935 who have a domain name for their afs servers which could not be mapped
939 * afs_config.exe now validates cell names against DNS in addition
940 to the CellServDB file.
942 * In order to allow the freelance client to connect to a volume with ID
943 equal to 1 on the default cell we changed the fake root.afs volume ID
944 once again. This time we choose 0xFFFFFFFF. In addition, we change
945 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
946 It will now be impossible for a volume ID to match that of another
947 cell unless the client is connected to 0xFFFFFFFD cells. That should
948 be enough room for growth.
950 * Fix "fs mkmount" command to work with UNC paths and when
951 started from non-AFS drives. It is now possible to create a mount
952 point in the freelance fake root.afs volume with the command
954 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
958 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
959 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
961 * The algorithm used to re-attempt access to the servers associated with
962 a volume has been altered to properly address the case in which all
963 servers have been marked down. The previous algorithm did not reset
964 the server's down flags so the servers were never actually retried.
965 This caused a problem with active volumes if the network connectivity
966 was lost as could be the case with a network cable removal, wireless
967 drop, or laptop hibernation. With the fix volume access is restored
968 almost instantenously when network connectivity becomes available.
970 * Support for SMB/CIFS browsing has been added to the AFS Client Service
971 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
972 listing of AFS submounts and freelance mount points. Support for
973 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
974 significantly enhances the behavior of AFS volumes within the Explorer
975 Shell. For instance, "AFS" now shows up as server in the Explorer
976 with each submount or freelance mount point visible as a share.
977 The right click menu in each folder now works with full functionality
978 on a consistent basis.
980 * The network provider can be configured to have different behavior
981 depending on the domain that the user logs into. These settings are
982 only relevant when using integrated login. A domain refers to an
983 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
984 local machine (i.e. local account logins). The domain name that is
985 used for selecting the domain would be the domain that is passed into
986 the NPLogonNotify function of the network provider. (see registry.txt
989 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
990 "Authentication Cell" which may be used to specify a default
991 authentication cell for afscreds.exe which is different from
992 the default cell for the AFS Client Service daemon.
994 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
995 afslogon.dll moved to %WINDIR%\System32\.
996 New registry entries added to register the dll for Winlogon events.
998 The logoff event will now force a call to ktc_ForgetAllTokens()
999 using the context of the user being logged off as long as the
1000 user's profile is not loaded from within AFS. If the profile
1001 was loaded from AFS we can't release the tokens since the Logoff
1002 event is triggered prior to the profile being written back to
1003 the its source location. This is now performed in an XP SP2
1006 * Windows XP SP2 Internet Connection Firewall interoperability
1009 * The %WINDIR%\afsdsbmt.ini contains four sections:
1010 Submounts, Drive Mappings, Active Maps and CSC Policies.
1011 The Submounts and CSC policies are now stored in the registry under
1012 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
1013 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
1014 The Drive Mappings and Active Maps are stored in the registry under
1015 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
1016 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
1018 There is no automatic migration of this data as it would be impossible
1019 to consistently migrate data to user profiles which may not be active
1020 when the machine is updated.
1022 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
1023 fake root.afs volume. For the same reasons as for the cellservdb file,
1024 this information should not be in %WINDIR%. This information is now
1025 kept under the registry key
1026 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
1028 The data from the afs_freelance.ini file will be automatically
1029 migrated to the registry on first execution of afsd_service.exe
1031 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
1032 troublesome for several reasons. One, it is confusing for those who
1033 expect the file to be named "CellServDB" instead of "afsdcell.ini".
1034 Two, this file is not a Windows Profile formatted file. Three,
1035 applications should not be reading or writing to %WINDIR%. It causes
1036 problems for Windows Terminal Server.
1038 The new location of CellServDB will be the OpenAFS Client install
1039 directory which is by default C:\Program Files\OpenAFS\Client and can
1040 be determined by querying the registry for
1041 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
1043 The existing afsdcell.ini will be migrated by the NSIS installer.
1044 The Wix installer must still be updated to do the same.
1046 * Change NSIS installer to use DNS by default; to remove Integrated Logon
1047 High Security mode; and to add Terminal Services compatibility registry
1048 entries to allow the OpenAFS tools to find the afsdcell.ini and other
1049 configuration files in %WINDIR%.
1051 * Add support for authenticated SMB connections. This will remove
1052 the need for high security mode in most situations. Both NTLM
1053 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
1054 only NTLM can be used even though Kerberos is now supported. The
1055 reason is that it is not possible to construct a service principal
1056 which is unique to each individual machine.
1058 SMB Extended Auth does not work on XP SP2 unless one of two registry
1059 modifications are made:
1061 (1) To disable the check for matching host names on loopback connections
1062 set this key. This does not require a reboot:
1064 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
1065 "DisableLoopbackCheck"=dword:00000001
1067 (2) To add the AFS SMB/CIFS service name to an approved list. This
1068 does require a reboot:
1070 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
1071 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
1073 afsd_service.exe will automatically add the current Netbios Name
1074 to the BackConnectionHostNames list and then temporarily disable
1075 the loopback check for one cycle of startup/shutdown of the service.
1076 We assume most folks do not start/stop without a reboot so this
1077 will be adequate in most cases.
1079 * Fix security hole in afslogon.dll which allowed passwords to be
1080 sent in clear text to the KDC in a misformed principal name.
1082 * Fix cm_GetCell() to properly handle expired dns entries
1085 * If Freelance mode is active and the afs_freelance.ini
1086 file does not exist, do not create an empty file.
1087 Instead create a file containing ro and rw mountpoints
1088 to the default cell using the standard conventions.
1090 * Modify the Freelance support to handle the ability
1091 to create rw mount points in the fake root.afs volume.
1093 * Changed the RPC mechanism used for token setting from
1094 named pipes to local. Use of named pipes can be restored
1095 by setting the environment variable AFS_RPC_PROTSEQ to
1098 Named pipes were required when a Windows 9x system was
1099 using a NT system in gateway mode which is incompatible
1100 with our use of local loopback adapters.
1102 * In afscreds.exe, if a username of the form user@REALM is
1103 specified and no password is specified, do not perform a
1104 kinit operation. Only perform the aklog functionality.
1106 * Add a new registry value which allows the number of processors
1107 on which afsd_service.exe executes to be restricted. Valid
1108 values are 1..numOfProcessors
1110 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
1114 * A second MSI based installer option is now available.
1116 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
1117 request tickets for user/instance@REALM instead of just user@REALM
1119 * Modify the Power Management Notify routine to wait for the Hard Dead
1120 timeout period instead of a fixed 19 seconds. With the longer timeout
1121 periods Hibernation and Standby could never succeed when network
1122 connectivity is not available.
1124 * The following fs.exe commands are now restricted to Administrator:
1125 - checkservers with a non-zero timer value
1128 - sysname with a new sysname list
1137 setting the default sysname for a machine should be done via the
1138 registry and not via "fs sysname".
1140 * NSIS installer adds options to install Debugging Symbols
1141 and the Microsoft Loopback Adapter; the user is now also
1142 given the ability to select the afscreds.exe startup options.
1144 * Build system modified to generate symbols for FREE (aka RELEASE)
1145 builds as well as CHECKED (aka DEBUG) builds
1147 * Sites which have a volume ID of 0x20000001 assigned to their
1148 root.cell volumes have been experiencing problems with accessing
1149 the root.cell volume of their cell when Freelance mode has been
1150 active. This was because 0x20000001 was assigned to the fake
1151 root.afs volume created by freelance. The fake volume id is
1152 now set to 0x00000001 to prevent conflicts.
1154 * The timeout logic in the AFS Client Service has been wrong
1155 for sometime. It is based on two different assumptions.
1156 First, the SMB client timeout is a fix value as was the case
1157 with OS/2 Lan Manager. This assumption is incorrect. The
1158 SMB timeout in Windows is a dynamic value computed based upon
1159 a fixed minimum timeout to which is added time based upon the
1160 size of the request and the performance characteristics of
1161 the connection. Second, it is the responsibility of the
1162 SMB Server to enforce the timeout requirements of the client.
1163 This is untrue. The SMB Server cannot be expected to know
1164 the requirements of the client. More importantly, if the
1165 SMB server uses the SMB client timeout as a value to restrict
1166 its behavior as an RX client, the performance characteristics
1167 of the local SMB session would be used to prematurely terminate
1168 WAN connections with significantly different performance
1171 The timeout logic has therefore been modified in the following
1173 . the Lan Manager Workstation (SMB) Session Timeout is used only
1174 as a basis for configuring the Connection Dead Timeout
1175 and Hard Dead Timeout values. The Connection Dead Timeout
1176 must be at least 15 seconds longer than the SMB Timeout
1177 and the Hard Dead Timeout must be at least double the
1178 Connection Dead Timeout.
1179 . New registry entries have been added to allow the Connection
1180 Dead Timeout and Hard Dead Timeout values independent of the
1181 Lan Manager Workstation Session Timeout
1182 . The test to enforce the SMB Client Timeout has been removed.
1184 One of the side-effects of removing the enforcement of the SMB
1185 Client Timeout is that regardless of whether or not the SMB client
1186 is available to receive the response (and how would the SMB server
1187 know) the RX protocol response can be used to update the AFS
1188 Client Service state for ready access by future SMB client
1191 This should be the end of the "Server paused or restarting messages"
1193 * Add support for arbitrary UNC paths to the pioctl() support.
1194 This enables the fs commands as well as the AFS Shell Extension
1195 to work correctly when UNC paths are being used.
1197 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1198 DNS if the cell configuration cannot be determined via CellServDB
1200 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1201 are ever set more than once at a time
1203 * Fix the management of lists of cm_cell_t structures when using
1204 DNS to lookup cell information. The previous code would fail to
1205 reuse the same cellID for a cell if DNS was used more than once
1206 for a given cell name. When the ttl expired, a single cm_cell_t
1207 could be inserted into the cm_allCellsp list more than once
1208 producing a loop. In addition, the vlServerp list belonging to
1209 the cell was not freed resulting in improper refCounting of the
1212 * Add DNS support to cm_IoctlNewCell() which previous only examined
1215 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1216 to properly garbage collect cm_server_t objects
1218 * Add numVCs variable to smb.c to track the number of smb_vc_t
1219 objects created and use it to initialize the vcID field which
1220 previously was set to 0 in all objects resulting in FindByID
1223 * Fixed DNS lookups to work consistently throughout the OpenAFS
1224 product instead of just from within the afsd_service.exe
1226 * Added a runtime check to ensure that AFS Client Service SMB
1227 Server is accepting connections before attempting to mount
1230 * Read IP addresses for volume servers out of the CellServDB
1231 file if gethostbyname() on the hostname fails.
1233 * Fix getcellconfig() to populate both the Hostnames as well
1234 as IP addresses when loading cell data via DNS
1236 * Increase the Connection Dead Time to 50 from 20 seconds
1237 Increase the Hard Dead Time to 120 from 40 seconds
1238 (matches the Unix values)
1240 * Fixed an assertion validating the number of allocated NCBs
1242 * Fixed the build environment to consistently build for
1243 Windows 2000 and above. (APPVER = 5.0)
1245 * Fixed rx_debug to properly validate the receipt in incoming
1246 data with select() and recvfrom(). Do not copy data out of
1247 the socket buffer unless success is indicated.
1250 * afsd_service.exe will now display a message box to the
1251 desktop when it terminates due to an IP Address Change.
1253 * installer no longer deletes AFS Server configuration data
1256 * installer generates a warning dialog if the RPC service
1257 is not properly configured
1259 * installer compressed with lzma instead of bzip2
1261 * afsd_service.exe shutdown crash solved once and for all
1263 * reference counting of smb_vc_t data structures improved
1265 * name space collision of smb_fid_t event objects corrected
1267 * the output of "fs memdump" is now written to
1268 %WINDIR%\TEMP\afsd_alloc.log
1270 * the file TaAfsApp_1033.dll is now properly installed allowing
1271 the User Manager to start
1273 * a new algorithm is used for computing filename pattern matches
1275 * afscreds.exe now accepts user names containing instance
1278 * Fix the Directory Name Lookup Cache to be case-sensitive.
1279 This is crucial in environments in which a Windows client
1280 is accessing a directory with more than one filename that
1281 differs only by case. If the directory contains "FOO"
1282 and "Foo". You want "DEL Foo" to delete the correct one.
1283 We still have a problem in that "DEL foo" will delete a
1284 random filename. This will be addressed in a future release.
1286 * Fix afscreds.exe -M option (renewMaps) to work when High
1287 Security mode is off. Also, remember to disable the ActiveMap
1288 flag in afsdsbmt.ini when a drive mapping is removed.
1290 * Updates to NSIS installer script. AFS Server configuration
1291 data will not be destroyed on un-install or re-install.
1292 Use a better compression algorithm.
1294 * afslogon.dll now uses KFW to obtain tokens when available
1296 * afslogon.dll when given an all uppercase username will
1297 attempt to authenticate with both the uppercase name
1298 and an all lowercase variation
1300 * DST modification removed. The fix appears to make things
1301 worse after a reboot of the machine.
1303 * fs.exe: added "cscpolicy" which is used to
1304 change client side caching policy for AFS shares
1306 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1307 [-documents] [-disable] [-help]
1309 * Several uninitialized variables have been initialized
1311 * It is now possible to obtain tokens using cross realm
1312 Kerberos within afscreds.exe:
1314 user: jaltman@ATHENA.MIT.EDU
1316 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1317 will will in turn be used to obtain afs@DEMENTIA.ORG.
1318 The resulting token will be stored with the display name
1319 jaltman@ATHENA.MIT.EDU@dementia.org
1321 * aklog.exe has been added to the client
1323 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1324 [[-p | -path] pathname]
1328 -d gives debugging information.
1329 krb_realm is the kerberos realm of a cell.
1330 pathname is the name of a directory to which you wish to authenticate.
1331 -noprdb means don't try to determine AFS ID.
1332 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1333 (default is Kerberos V)
1334 No commandline arguments means authenticate to the local cell.
1337 * All of the resource files have been restructured to adhere to
1338 a set of rules IBM implemented for loading string resources.
1339 These rules had either been forgotten or were not discovered
1340 by folks working on the OpenAFS sources. The end result was
1341 memory corruption. This is primary item which was preventing
1342 the AFS Server from working.
1344 * Increased the size of the maximum ticket size stored in a token
1345 from 344 bytes to 12,000. Increased the buffers used to convey
1346 messages between the pioctl() caller and the SMB Server from
1347 1000 bytes to 12,512. The code appeared to have been writing
1348 above the top of the stack by quite a few number of bytes.
1349 (The increased ticket size is necessary for the next item.)
1351 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1352 Instead the raw Kerberos 5 ticket is used in its entirety. This
1353 is extremely important as it allows us to use pure Kerberos 5 KDCs
1354 as the source of the AFS authentication. The use of up to 12,000 byte
1355 tickets will allow tickets produced by all versions of Microsoft
1356 Active Directory to be used.
1357 - create a user account.
1358 - designate it DES only
1360 - specify its UPN to be "afs@realm"
1361 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1363 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1364 is special when using long file names. (you must use "*.*" and not "*")
1365 Instead only enforce it when performing 8dot3 searches.
1367 * Fixed the DST problem with creation times being set one hour ahead
1369 * Fixed the problem when using \\afs\cell-alias. For example,
1370 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1371 for the alias name; instead simply expand the name. One of the
1372 symptoms of this problem was a loss of acquired tokens.
1374 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1375 of strings. (Only English strings provided.)
1377 * Fixed the installer to properly replace in use files.
1379 * Fixed the build system to cleanup generated component version files
1381 * The release build compiled with MSVC 6.0 compiler to avoid the
1382 afsd_service.exe shutdown crash. This does not solve the problem
1383 but simply avoids it for the time being.
1387 * fix afslogon.dll to not corrupt memory when High Security mode
1390 * fix afsd_service.exe to not attempt to restore the stack when
1391 an exception occurs. (not safe in multi-threaded programs)
1393 * fix uninstaller to properly remove the CRT and MFC DLLs
1395 * remove a Message Box from afscreds.exe when getcellconfig()
1396 fails on a kerberos realm which is not a cell
1398 The following is a list of changes to the OpenAFS for Window client
1401 * "fs setserverprefs" will leave afsd service deadlocked
1403 * "vos listaddrs" will core dump
1405 * installer sets the appropriate keys to support Integrated Logon
1407 * installer disables the "Find Lana by Name" functionality as it
1408 was causing headaches for many users
1410 * fix the intermittent crash of the power management thread when
1411 shutting down the AFS Client Service
1413 * optimizes the obtain drive mount list functionality which is
1414 executed every time the mount tab in afscreds.exe and afs_config.exe
1415 are refreshed. (this happens a lot)
1417 * fix the service shutdown logic. add the STOP_PENDING state
1418 and do not accept additional service events after we declare
1421 The following is a list of changes to the OpenAFS for Window client
1424 * flexelint was run against the source tree and hundreds (perhaps
1425 thousands) of corrections were applied to ensure prototypes
1426 were in use; types were used consistently; variables were
1427 initialized; unused variables were removed; etc.
1429 * A wide variety of instrumentation was added including the
1430 ability to produce a stack trace from within afsd_service.exe
1433 * Dynamic configuration of the RDRtimeout value based upon the
1434 LanMan Workstation Session Timeout
1436 * The mount root no longer needs to be called "/afs". This
1437 is now set by a registry value "MountRoot" within the key
1438 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1440 * The cell list is now only read out of afsdcell.ini when the
1441 file changes instead of each time a cell is resolved.
1443 * Thread synchronization was added to cm_server.c and ktc_nt.c
1445 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1446 calloc()/free(). The Global functions were needed on Windows 3.x
1447 but have caused a variety of problems on the Win32 platforms.
1448 Avoiding them is highly recommended by several Microsoft
1449 Knowledgebase articles
1451 * Support for Symbolic Links added to the AFS Shell Extension
1453 * Added a registry value "OverlayEnabled" to determine if
1454 Shell Extension Overlays should be enabled.
1455 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1457 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1458 separate trees for checked and free builds. Build system supports
1459 a custom directory src\WINNT\extra which can be used as a grafting
1460 location of organization specific additions to the build tree.
1462 * New installer built using NSIS 2.0.
1464 * Named all kernel objects in order to allow them to be monitored
1465 with tools such as SysInternals' ProcExp.exe.
1467 * Introduced new EventLog framework for AFSD
1469 * Introduced Power Management interface to AFSD for Standby and
1470 Hibernate modes to allow cache to be flushed prior to network
1473 * Utilize Win32 DNSQuery API instead of internal routines. This
1474 allows DNS SRV queries to be sent to all current domain name
1475 servers. Not just one specified in an INI file. DNS is now
1478 * "NetbiosName" registry value may be used to specify a fixed
1479 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1480 when the loopback adapter is in use. If you need to use the
1481 old notation with a loopback adapter installed specify a registry
1484 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1486 * Refactor all modules which depend on LAN Adapter and NetbiosName
1487 determination in a new library: lanahelper.lib. This allows for
1488 consistent behavior throughout the product.
1490 * Move the afsd.log and afsd_init.log files to the directory specified
1491 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1492 for services. Added the Date to the log entries.
1494 * New registry value "RxMaxMTU" used to limit the size of the RX
1495 packets sent by the AFS Client Service to the Server. In order
1496 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1497 size must be restricted to 1264 or smaller. The latest NSIS
1498 installer sets a value of 1260 by default.
1500 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1501 packets. This is not needed in order to work across the Cisco
1502 VPN but might be needed for other network environments. This
1503 value is not set by the NSIS installer.
1505 * New registry value "HideDotFiles" is used to apply the Hidden
1506 attribute to files whose names begin with a '.'. This value
1507 is set by the NSIS installer.
1509 * New registry value "MaxMpxRequests" allows the maximum number
1510 of multiplexed sessions to be configured at run time. This
1511 value is not set by the NSIS installer. The default value is
1514 * New registry value "MaxVCPerServer" allows the maxmimum number
1515 of VCs per server to be configured at run time. This value is
1516 not set by the NSIS installer. The default value is 100.
1518 * New registry value "AllSubmount" allows the "all" submount to
1519 be disabled by setting its value to 0x00.
1521 * Allow cells names to be valid mount points
1522 \\<netbiosName>\<cellname>
1524 * Store the active state of drive mappings in order for afscreds.exe
1525 to restore them upon startup
1527 * Add exception handling to generate a Stack Trace to the afsd_init.log
1528 file if one happens to occur.
1530 * Add lots of logging to help detect the cause of invalid SMB packets
1532 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1533 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1534 renewal of expiring tokens as long as afscreds.exe is running.
1536 * New afscreds.exe command line options:
1538 -M = renew drive maps
1539 -N = ip address change detection
1542 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1543 determines whether or not MIT Kerberos for Windows should be used
1544 to obtain tokens via Kerberos 5 tickets.
1546 * New registry value "AfscredsShortcutParams" in
1547 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1548 determines the command line parameters to be specified when "fixing"
1549 the AFS Shortcut in the user's startup folder.
1551 * The "ShowTrayIcon" registry value has been moved from
1552 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1553 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1555 * The <cell name> registry values used to store the token expiration
1556 reminders have been moved from
1557 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1558 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1560 * Obtain the Logon User Name from the Explorer key when available
1562 * new text document doc\txt\winnotes\registry.txt lists all registry
1563 values used by OpenAFS (excluding the AFS Server)
1565 * BUG: rx_securityClass objects were not properly reference
1566 counted and were never freed.
1568 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1569 would be generated. The existence of a server does not imply
1570 that it is not down. If all of the servers for a cell are down
1571 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1574 * BUG: the directory name lookup cache failed to free the entries
1575 in the cache when the name cache entries cycled. The entries
1576 in the cache would become dereferenced without being freed.
1578 * BUG: fs setserverprefs could be executed without Administrator
1581 * BUG: the number of allocated NCB objects (100) exceeded the number
1582 which could actually be waited upon by the kernel (64). Any objects
1583 which were utilized above the limit could never have event completions
1586 * BUG: smb_username_t objects were not being reference counted and
1587 were not properly freed.
1589 * BUG: smb_tid_t objects could under unusual circumstances be freed
1590 before they were no longer referenced.
1592 * BUG: smb_fid_t object pointer were frequently used even when
1593 their value could be NULL. They were not properly released and
1594 therefore they were never freed.
1596 * BUG: smb_packet_t data structures were not completely initialized
1599 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1600 Denied" because that causes the Explorer Shell to try again until
1601 access is obtained. Instead return "Remote Resources" which allows
1602 the shell to move on and treat the error as transient.
1604 * BUG: when initializing the NCBreturns structure, separate Event objects
1605 were created for each NCB although a single Event object was supposed
1606 to be shared by all.
1608 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1611 * BUG: smb_tran2Packet_t objects were not being properly referenced
1614 * BUG: directory path creation did not handle the case of multiple
1615 directories requiring creation in one attempt
1617 * BUG: SMB requests which required an Extended Response were ignored.
1618 This prevented some files from being written to AFS volumes.
1620 * BUG: character strings were being freed even after they were
1621 inserted into in use data structures
1623 * BUG: inconsistent usernames were used when High Security mode was
1624 enabled. (there is still much to do in this area)
1626 * BUG: pioctl() calls which require out of band RPC operations were
1627 susceptible to race conditions when performed by multiple processes
1629 * BUG: memory allocation and deallocation crossed instances of the
1630 C Runtime Library producing memory leakage and corruption in
1631 afscreds and the client configurator.
