2 * "fs wscell" when executed in freelance mode will return the
3 name of the cell configured in the registry. The root.afs
4 volume is not loaded from this cell, but it is used for the
5 default for aklog and integrated login.
7 * "fs mkmount, fs rmmount, symlink make, symlink remove" will
8 no longer work on \\AFS\all when freelance is being used
9 unless the user is a member of the "AFS Client Admins" Windows
12 * some more checks performed during persistent cache validation.
15 * Optimize calls to cm_CheckServer from cm_Analyze. Only check
16 down servers for the current cell not all cells.
18 * If the scache LRU list becomes corrupted, the AFS Client Service
19 might enter an infinite loop at startup. Detect the corruption
20 and discard the cache contents in this case.
22 * Fixed the Explorer Shell's remove mountpoint functionality.
24 * Fixed a deadlock caused by the holder of cm_aclLock attempting to
25 obtain a mutex lock on a cm_scache_t object whose lock is held by
26 a thread attempting to obtain the cm_aclLock.
29 * Really fixed DNS AFSDB queries to ensure that "csail" cannot be
30 misinterpretted as "csail.mit.edu" when the resolver
31 is configured to append ".mit.edu" to failed DNS queries.
33 * Added a new registry key, "LogoffPreserveTokens" (see registry.txt),
34 that can be used to force the preservation of user tokens upon logout.
36 * Update the NSIS install scripts to use NSIS 2.07. This release adds
37 recommended installation categories: AFS Client, AFS Administrator,
38 AFS Server, AFS Development Kit. Each category includes a different
39 default subset of the OpenAFS components.
41 The OpenAFS logo is now associated with the NSIS uninstall entry
42 in the Add/Remove Programs control panel.
44 * The user name associated with AFS tokens when obtained with
45 integrated login, the afs systray tool, or aklog will always
46 include the full Kerberos 5 user principal name regardless of
47 whether or not the cell is local to the realm.
49 * Eric William's IFS redirector has been checked onto the CVS head.
50 This code is experimental at the current time and is not being
51 incorporated into the 1-4 branch releases. Instructions for
52 building from sources are found in the top-level README-NT file.
54 * Modify integrated login so that it does not enter an infinite
55 loop if the service is not set to auto start.
57 * Added asetkey.exe used to set a Kerberos 5 key for use by the
60 * Added uninstall.exe to Wix installation
62 * More modifications to algorithms used to wake sleeping threads.
66 * Changes to the algorithms used to wake threads when they are
67 put to sleep because of conflicts over buffer operations.
70 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
71 the process of producing AFS tokens. The tokens are stored within
72 the AFS Client Service but the Kerberos 5 tickets have been discarded.
73 New functionality has been added to temporarily copy the tickets to
74 a file ccache during the short window between the NPLogonNotify and
75 WinLogon Logon Event. The Logon Event handler starts a process as
76 user, afscpcc.exe, that copies the tickets into the default ccache.
77 The file ccache is then destroyed by the event handler.
79 * During synchronization operations on stat cache entries, if threads
80 are forced to sleep it was possible that the threads would not be
81 woken under heavy load.
83 * Enforce the delete on close flag specified by the NTCreateX()
86 * A race condition in the rx library was fixed that resulted in
87 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
88 was cleared when threads were still waiting to use the
89 connection. Also, fixed a potential case in which the
90 connection could be destroyed while threads were waiting to use it.
92 * The DNLC freelist has been seen to become corrupted with still
93 active entries being stored on the freelist. Changes were made
94 to perform a better job of cleaning entries before placing them
95 onto the freelist; marking them with the correct magic value when
96 purging the list; and allowing the list to be purged on startup
97 if the cache validation fails.
99 * Windows Crash Reporting does not get triggered for afsd_service.exe
100 because it provides its own top level exception handler. This patch
101 places an explicit call to ReportCrash() on platforms which support
104 If you configure Crash Reporting via AD Policy to capture crash
105 reports within the domain, then you will receive this output.
107 * Generate MiniDumps independent of the Windows Crash Reporting.
109 (a) If an exception occurs,a minidump will be generated at the path
110 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
111 can be set to any other type via use of the
114 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
116 (b) MiniDumps can be generated at any time using the "fs minidump"
117 command. This allows you to generate a minidump without
118 stopping the process or even requiring the use of a debugger
121 * an RX connection which reports bad ticket now treats it the same way
122 the expired ticket is treated. The ticket is removed from the
123 connection and a new anonymous connection is established.
125 * fs memdump now requires that the caller be in the AFS Client Admins
128 * additional debugging information is provided in cm_Analyze when the
129 error code is ignored.
131 * Fix a regression introduced into the pioctl() client code which
132 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
133 MIT KFW is not installed. (1.3.82a)
135 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
138 * Fix a race condition in cm_EndCallbackGrantingCall() that
139 could leave 'nrevp' pointing to freed memory. In the process,
140 optimize the processing to ensure that the applications monitoring
141 the status of the stat cache entry are only notified at most
144 * Conditionalize access to the Explorer Shell AFS->Mount Point
145 ->Remove menu item. Disable the item if the selected item(s)
146 are not mount points.
148 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
149 Local Storage. This eliminates thread contention on the
150 global RX free packet queue. This should improve performance
151 on multi-CPU systems.
153 * Fix the IP address filtering code to properly load/unload
154 the IPHelper DLL so that Windows XP/2003 and beyond systems
155 do not have to manually probe the registry.
157 * CleanupACLEnt() was not being called consistently with
158 the cm_scache_t object referred to by the back pointer
159 mutex locked. This could in very rare conditions lead to
160 an invalid memory access.
162 * Added a script command to the msi installer "afs_replace"
163 which can be used to replace one version of OpenAFS with
164 another without requiring an uninstall and reinstall if
165 the installed msi is no longer in its original location.
167 * Apparently the problem with multi-domain forests with cross-
168 realm trusts to non-Windows realms was not entirely solved.
169 The authentication to the AFS SMB service failed because
170 the wrong name was being used. Using ASU as an example,
171 the authentication was being performed with the name
172 "QAAD\user" (an account in the forest root) and not
173 "user@ASU.EDU (the MIT Kerberos principal used to login with)
175 The solution was to add an additional dependency on KFW
176 in order or to be able to easily obtain the client principal
177 name stored in the MSLSA ccache TGT. This information is
178 used in two locations:
180 - the pioctl() function
182 - a new WinLogon Event Handler for the "logon" event.
184 The pioctl function will now be able to use the correct
185 name when calling WNetAddConnection2() and the "logon"
186 event handler will now be able to call WNetAddConnection2().
187 The hope is that the "logon" event handler will be called
188 before the profile is loaded but I have not guarrantee
192 * Fixed a locking error in cm_TryBulkStat() which had the
193 potential of deadlocking the system for the length of time
194 it takes to perform a bulk status fetch operation.
196 * Replaced time conversion code (UnixTime <-> FILETIME) to
197 be completely arithmetic instead of relying on a bizarre
198 algorithm involving a variety of C RTL time functions.
199 This has the side effect that UnixTime and FILETIME which
200 are both stored in UTC are interpretted as UTC throughout
201 the year. Windows will apply the same localization to AFS
202 as it does to NTFS. Applications which rely on the ability
203 to sync files between the two file systems will no longer
204 see the timestamps of files in AFS change an hour relative
205 to the files stored in NTFS or Windows based backup devices.
207 * Fixed a invalid memory access under a bizarre circumstance.
208 Windows will allow a physical mass media device to be
209 installed via Plug N Play to the system and will assign it
210 the lowest available drive letter. This is true even if the
211 drive letter is currently assigned in the user session to
212 a network device via NET USE (or its equivalent.) When this
213 happens, queries sent to the CIFS server will contain invalid
214 data. This invalid data was not being caught by the AFS
215 Client Service and was resulting in a crash when Freelance
218 * Fixed a reference count error when registering callbacks
219 on a stat cache object if the callback was already registered
221 * Add a case to cm_Analyze() in order to handle the case where
222 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
223 the server list for the volume is empty. In this case, force
224 an update of the volume info and retry.
226 * Insert a missing cm_EndCallbackGrantingCall() which could
227 result in threads waiting for a callback to complete to never
230 * In the persistent cache, there is a maximum number of volume
231 entries. Allow volume entries to be reused if the maximum
232 number have been allocated and their reference count is zero.
234 * If we already have a dead virtual connection object, don't
235 ignore the fact that additional dead vc objects must be taken
238 * Removed a deadlock condition introduced in the summer of 2004.
239 Do not hold mx locks around calls to RX functions including
240 rx_NewCall(). That is what reference counts on the rx_connection
243 * Fixed an initialization error in afslogon.dll which could
244 result in random behavior including a failure to terminate
245 the NPLogon function. (1.3.80b)
247 * Fixed an error preventing the use of SMB authentication
248 on Windows 2000. (1.3.80a)
251 * Updated CellServDB to Public CellServDB 16 Mar 2005
253 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
254 misinterpretted as "csail.mit.edu" when the resolver
255 is configured to append ".mit.edu" to failed DNS queries.
257 * Fixed another case in which the client would replace connections
258 to the host when it was not necessary. In this case the
259 situation would occur if cryptall was on and the connections
260 were unauthenticated due to lack of an appropriate token.
262 * OpenAFS for Windows has failed to work at sites which are
263 utilizing a cross-realm trust between an MIT/Heimdal realm
264 and a multi-domain Windows forest when the workstation being
265 accessed is not located in the root domain. This is caused
266 by a bug in the workstation which was triggered after the
267 introduction of Windows 2003 Server. When the bug is triggered,
268 the workstation attempts to authenticate users to afsd_service.exe
269 by contacting the Domain Controller instead of using the
270 LSA loopback authentication mechanism.
272 One of the reasons this bug occurs is because the workstation
273 does not have a reliable way of knowing that the service whose
274 netbios name is "AFS" is located on the workstation. This will
275 be fixed starting in Longhorn Beta 1 by Microsoft. The
276 "BackConnectionHostNames" registry value will be used to
277 indicate that the authentications to that service name should
278 be performed using the loopback authentication mechanism.
280 In the meantime, when Logon Caching is enabled, we can force
281 afsd_service.exe to authenticate using the logon cache before
282 contacting the Domain Controller. This will work with both
283 password and smart card based logons.
285 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
286 flag should not be cleared if a volume's server reference is
287 marked as "offline". In the case where all of the volume's
288 servers are either "down" or the volumes are "offline", we want
289 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
290 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
291 should never occur in practice.
293 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
294 5 seconds, clear the server down and volume busy flags, and
295 then force an update from the VLDB. This allows the client to
296 update the location of a volume if the reason for it being
297 marked offline is because it is being moved. Calls to
298 cm_ConnByMServers() will be retried either until success or
299 the RDRtimeout period is reached.
301 * Correct the Power Management code behavior in response to
302 Standby, Suspend, and Shutdown events. Instead of flushing the
303 buffers associated with the mounted SMB submounts, simply write
304 all buffers which are marked dirty.
306 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
307 provides a list of cells other than the default cell for which
308 tokens should be obtained using the default Kerberos principal.
309 This functionality is logon domain specific and is only available
310 when using KFW for authentication.
312 * Fixed FindNext Invalid Handle error caused by over agressive
313 attempts at garbage collecting dirSearch entries when the
314 dirSearch ID wraps from the maximum value to 1.
316 * Add support for registry defined server preferences for VLDB and
317 File servers. See registry.txt for details.
319 * Increased default cache size to 96MB and default number of cache
322 * Fixed refCount leaks related to directory lookups and pioctl calls.
324 * Callbacks revoked during a race condition with an attempt to
325 obtain the same callback no longer result in an inaccessible
328 * New command line tool:
330 afsdacl : Set or reset the DACL to allow starting or stopping
331 the afsd service by any ordinary user.
333 Usage : afsdacl [-set | -reset] [-show]
335 -reset : Reset the DACL
336 -show : Show current DACL (SDSF)
338 * IP addresses are no longer queried once at startup. Instead IP
339 addresses are obtained as needed. Loopback adapter addresses are
340 no longer published to the server.
342 * Pay attention to the MIT KFW registry configuration for automatic
343 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
345 * Fix (once again) case-sensitive comparisons which was apparently
348 * Activate support for vos listvol -format
350 * Population of the "AFS Client Admins" group failed on non-English
351 versions of Windows because the name of the "Administrators" group
352 is localized. Now we lookup the name of the group by using the
353 Administrators Group Alias Relative ID.
355 * Multiple cell token acquisition within afscreds.exe was broken in the
356 case of Kerberos 5 cross realm authentication. Instead of contacting
357 the KDC associated with the cell's realm, afscreds would obtain a
358 token from the KDC of the user's realm. This would result in
359 "invalid kvno errors" while authenticating to the AFS servers.
360 Unauthenticated access would work. The symptoms would vary based upon
361 whether or not the VLDB servers had been contacted using unauthenticated
362 connections prior to the user obtaining tokens.
364 * The list of ACL entries was becoming corrupted. It appears as if
365 an ACL when it expires was not being appropriately cleaned up. In
366 fact, it was left in the list of ACLs associated with the scache
369 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
370 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
371 and "amd64_win64" for amd 64-bit processors.
373 * When executing executables, Windows provides a mechanisms by which
374 the normal search for DLLs can be bypassed. If a file foo.exe is
375 being executed and there exists a file or directory "foo.exe.local"
376 (the contents are ignored if a file), then Windows will search for
377 DLLs first in the "foo.exe.local" directory and second in the
378 directory in which the "foo.exe" file is located.
380 Previous releases of OAFW would improperly return
381 STATUS_NOT_A_DIRECTORY instead of the expected
382 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
383 to terminate the search for the DLL causing the execution of the
386 * Rework the reference counting of smb_vc_t objects. The references
387 stored in the waiting locks were not counted. This could result in
388 an assertion if the reference count drops to zero.
390 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
391 when running in freelance mode.
393 * Added support for persistent caching of file contents, stat entries,
394 volume data, cell data, and name lookup data. When the registry
395 value, "NonPersistentCaching", is not defined or set to 0 the file
396 specified by "CachePath" becomes a persistent cache file. The
397 size of the cache file is computed at run time. It has a maximum
398 size of approximately 1.2GB. The contents of the file will be
399 validated according to the rules specified by the "ValidateCache"
402 * Added support for UUIDs. UUIDs are kept for as long as the
403 cache file is intact.
405 * Added cmdebug.exe and support cache manager debugging callback
406 interfaces in afsd_service.exe.
408 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
409 [-addrs] [-cache] [-help]
410 Where: -long print all info
411 -addrs print only host interfaces
412 -cache print only cache configuration
414 * Symlinks to \\AFS\[all\]... will now be treated the same as
415 symlinks to /afs/.... However, please use /afs/... as otherwise
416 the symlinks won't work on Unix.
418 * Correct a problem with local CellID allocation for cells whose
419 server list is obtained via DNS instead of a CellServDB file. If
420 the DNS information expires the CellID assigned to the entry will
421 be changed. This causes all of the cm_scache_t objects which refer
422 to the old cellID number to become useless. Attempts to access
423 files or directories with cm_scache_t objects using the old cellID
424 will fail since the server list cannot be obtained.
426 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
427 be triggered if the volume referenced by the cm_scache_t object is
430 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
431 in addition to SERVICE_ACCEPT_STOP.
433 * Move RPC shutdown until after the SMB and RX shutdown procedures
434 complete. Block until RPC shutdown is complete.
436 * Modify afslogon.dll (integrated logon) to wait for service if its
437 state is START_PENDING. If the timeout period occurs, reset to
438 the retry interval and not the sleep interval.
440 * When renewing the server list for a cell obtained via DNS AFSDB
441 records, the cm_cell_t entry must be removed from the list of all
442 cells. Otherwise, the list of cells will be corrupted.
444 * In the dcache and scache modules, use the cm_scache_t dataVersion
445 instead of the cm_fakeDirVersion.
447 * Synchronize fs.c with the unix version.
449 * The variable used to determine whether a file or virtual memory
450 mapped cache is used was not properly initialized to a default
451 value. If the registry setting "NonPersistentCaching" was not
452 set, the choice would be random. Properly initialized to be
455 * The memory mapped view was never unmapped before closing the file
456 at service shutdown. This is now properly cleaned up.
458 * Default location of Cache file is now %TEMP%\AFSCache
462 * A bug affecting new installations of 1.3.75/76 would result in
463 the creating of incorrect mountpoints in the freelance root.afs
464 volume for the default cell.
466 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
467 of "root.cell", you have been affected by the bug. To correct the
468 problem, execute the following commands:
470 fs rmmount \\afs\all\<cellname>
471 fs rmmount \\afs\all\.<cellname>
473 fs mkmount \\afs\all\<cellname> root.cell <cellname>
474 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
478 * A bug has been fixed in the auto-generation of Freelance root.afs
479 symlinks which produced random entries in the \\AFS\all directory.
481 * Support has been added for multi-homed servers
484 * Added a new registry value, "StoreAnsiFilenames", which can be used
485 to force the use of ANSI character sets instead of OEM Code Pages.
486 This feature is useful when users require the ability to create
487 filenames with 8-bit characters and need to access the files from
488 both Latin-1 based Unix systems as well as from Windows.
490 Activation of this feature will prevent access to files stored with
491 8-bit OEM characters.
493 * Shutdown all SMB threads in a synchronized manner when stopping the
496 * There is currently a maximum cache size of 1.3GB. The limit is imposed
497 by the largest contiguous block of unused memory within the 2GB process
498 space which can be assigned to the memory mapped file. Unfortunately,
499 when the executable digital signature verification code is activated
500 Windows sees fit to further segment the process memory which in turn
501 reduces the size of the maximum cache file to less then 800MB. If
502 larger cache sizes are desired, a new registry value should be set:
504 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
506 Setting this value will disable the runtime verification of digital
507 signatures on afsd_service.exe and the afs dlls which it loads. It
508 will not disable the the version number check on those same files.
509 The signature verification is not a security messure and is only meant
510 to enhance the ability to afsd_service.exe to detect potential
511 destablizing mixtures of DLLs from incompatible distributions.
513 Added code to auto-disable the signature verification check if
514 the desired cache size is greater then 700MB.
516 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
517 used to verify the validity of the afsd_service.exe binary
518 as well as each of the AFS DLLs loaded by the service. Not only
519 must the digital signature be valid but the signatures of the
520 DLL must be signed by the same entity as the service.
522 * Implement new functions: cm_freelanceMountPointExists and
523 cm_freelanceSymlinkExists. Use them along with other validity
524 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
525 ensure that name collisions do not occur and that empty strings
526 are not valid file names.
528 A symlink may not have a name which would resolve to a valid
529 cell name. Doing so would prevent access to the cell.
531 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
532 re-initialization code. The reference counts of the fake root.afs
533 volume scache object(s) would become invalid when the mount point
534 or symlink lists were altered.
536 * Add registry entries to provide mappings from the afsdsbmt.ini
537 to the new locations for applications which count on the use
538 of the old Profile file APIs. These apps are likely to fail
539 if the user does not have administrator privileges and the
540 registry is locked down.
542 * The afs_config.exe submounts dialog had two errors.
543 First, attempts to remove entries failed because the registry
544 key was being opened without KEY_WRITE privileges.
545 Second, when editing a submount entry, changing the name
546 would add a new key and leave the original one in place.
547 Now the original submount will be removed if its name is
550 * In recent months there have been several incidents in which
551 users have experienced problems starting or accessing
552 afsd_service.exe and after significant effort has been spent
553 it has turned out that they have two versions of AFS on the
554 machine or an inconsistent set of DLLs.
556 Code has now been added to afsd_service.exe which will walk
557 the list of modules loaded by afsd_service.exe and validate
558 that the version of the AFS DLLs matches the version of the
559 afsd_service.exe executable. If they do not match the service
562 * When Freelance mode is enabled and there is no registry
563 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
564 will attempt to import the afs_freelance.ini file contents.
565 If the file does not exist, it was creating a dummy file
566 with a r/o and r/w entry for the default cell and then
567 importing those values.
569 This process has been changed. The temporary file is no
570 longer created. Also, both the OpenAFS Client install
571 directory as well as %WINDIR% are checked for previous
572 afs_freelance.ini files.
574 * Added support for VL_GetEntryByNameN(). Still need to add
575 support for VL_GetEntryByNameU() for multi-homed support.
577 * Fix a deadlock situation in afscreds.exe when canceling an
578 auto-generated Obtain Tokens dialog
581 * Fix the locking of objects during Directory Searches in the
582 SMB/CIFS server. The failure to properly lock the reference
583 counts was resulting in the premature freeing of smb_dirSearch_t
584 objects while they were still in use by the SMB/CIFS client.
585 This does not solve the "Invalid Handle" problem.
587 * Fix Find Cell By Name pioctl call to return a valid cell
588 name for the Freelance fake root.afs volume.
589 "Freelance.Local.Root".
591 * Fix the Explorer Shell Extension Symlinks->Add operation.
592 The dialog template was missing and the link destination
593 string was too short.
595 * Add support for symlinks to Freelance root.afs volume
596 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
597 <number> = "<linkname>:<relative-path>."
598 Use symlink.exe to create, list, or remove
600 * Remove the fallback to the use of KFW's KRB4 library when obtaining
601 tokens. We never obtain KRB4 tickets.
603 * Fix AFS Client Configuration Control Panel to support new SysName
606 * Fix a bug in afsd_service.exe which could result in the SysName
607 not being read from the registry.
610 * Add code to block the issuance of AFS tokens by aklog.exe or
611 afscreds.exe when the Kerberos 5 principal name contains a dot.
613 * Modify the IsAdmin() function to always treat the local SYSTEM
614 account as an AFS client administrator. Affects fs.exe and
617 * Modify the internal handling of Quota Exceeded errors
619 * Upgrade all reference count fields in the Windows cache manager
620 and the osi library to use unsigned long instead of signed short.
621 A similar fix has been applied to the afs rpc (rx) library.
623 * fix the Windows cache manager to prevent it from replacing the
624 rx_connection object associated with the cm_conn_t object on each
625 and every operation if "fs crypt" was set. This explains the
626 dramatic performance difference when crypt is used vs clear.
627 The problem: 'cryptall', a boolean flag indicating whether or not
628 "fs crypt" is set, was being compared to the rx_connection
629 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
630 1 != 2 and therefore the rx_connection was always destroyed
631 and replaced on each and every operation.
633 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
634 It is not safe for the cm_conn_t object to not be locked because
635 rx_DestroyConnection might be called from another thread if:
636 - the user's tokens have changed or expired
637 - the crypt mode has changed
639 This fix appears to have also taken care of the problems associated
640 with Overlapped Writes resulting in Delayed Write errors.
642 * fix NSIS installer's AdminGroup.exe to properly create and
643 remove groups when given -create or -remove. The string comparison
646 * fs sysname now accepts a list of sysname values
648 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
649 DWORD which when set to a non-zero value will cause error message
650 text to be output to stderr from the pioctl() routine. Useful in
651 debugging failures of fs.exe, tokens.exe, etc.
653 * added a test to the power management code to only perform a
654 flush operation if there is at least one network adapter which
655 is not a loopback adapter.
657 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
658 "EnableKFW". This value will not be read if the key
659 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
660 value under that key does not.
662 * provide mechanisms to force the use of krb524d for Kerberos 5
663 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
664 there is a new registry value "Use524" and for aklog.exe a new
665 command line parameter "-m".
667 * Fix the pattern matching algorithm to properly match patterns
670 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
671 which is used by both the original function and the new
672 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
673 creation of HardLinks in addition to Renaming. smb_Link()
674 is a new function which creates HardLinks via cm_Link().
675 cm_Link() is a new vnodeops function which creates links
678 smb_ReceiveNTRename() does not support the File Copy and
679 Move Cluster Information operations described in its interface.
680 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
682 * When opening files via symlinks, we should follow the symlinks
683 until we reach the actual file stat cache entry. The stat cache
684 entry of the file should then be stored in the FID instead of
685 stat scache entry of the symlink.
687 * return bad operation errors for all unimplemented functions
688 even if we do not know the functions exist.
690 * Log bad packets and unknown operation packets to the trace log
692 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
695 * Update list of known CIFS operations to include all those listed
696 in CIFS-TR-1p00_FINAL.pdf.
698 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
699 to support the REG_EXPAND_SZ type.
702 * A new Windows authorization group "AFS Client Admins" is now
703 created and populated with the members of the "Administrators"
704 group. The group is used to determine which accounts on the
705 machine may be used to modify the AFS Client Configuration via
706 the UI and command line tools. afs_config.exe, fs.exe,
708 * Modify the WinLogon Logoff Event Handler to query NT4 domain
709 controllers for the remote profile path if Active Directory
710 services are not available.
712 * Fix aklog.exe to not add the AFS ID to the username
714 * PTS registration of new users to foreign cells has been added to
717 * The cm_Daemon thread is used to perform checks for
718 down servers, up servers, volumes, callback expirations,
719 lock maintenance and token expiration. Due to a gaff in
720 larger integer division the thread never performed any
721 work. Instead the current time computation would always
722 be less then the trigger times. This had an adverse affect
723 on the client's ability to maintain communication with servers,
724 keep volumes up to date, and flush user tokens and acls
725 when they have expired. This was broken when the 1.3 branch
726 was modified to support VC7 which no longer included
729 * An initialization problem with the Freelance code was
730 detected while fixing the callbackRequest. The cm_rootSCachep
731 object is obtained during afsd_InitDaemons() but the callback
732 information is incomplete. The callback information will not
733 be obtained until cm_MergeStatus is called from within
734 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
735 test for the conditions under which the callback information
738 * Reports have been filed indicating that callbacks were
739 being lost. An examination of the code indicated that the
740 cm_server_t objects were not being properly reference
741 counted by the cm_scache_t and cm_callbackRequest_t objects.
742 In particular, the cm_server_t objects may have been freed
743 from beneath the cm_conn_t objects.
745 All of the reference counting is now done via the functions:
750 this improves the ability to track the referrals.
752 Each cm_BeginCallbackGranting Call now allocates a reference
753 to the cm_server_t. The cm_EndCallbackGrantingCall either
754 frees the reference or transfers it to the cm_scache_t
755 cbServerp field. These are then appropriately tracked
756 through the cm_Analyze call.
758 * Ensure that the dnlc hash table is the same size as the
759 dir name hash table (as per original author's note).
760 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
761 for compatibility with 64-bit systems.
763 * fix smb_ApplyV3DirListPatches to properly apply the hidden
764 attribute to dotfiles when the infoLevel < 0x101 and
765 cm_SyncOp has failed.
767 * Fix the Freelance registry initialization code. There
768 was a possibility that some systems could end up with
769 garbage in the registry during a clean install.
772 * file and directory names beginning with "." will now be given the
773 hidden attribute when the volume access is anonymous. this matches
774 the behavior when the volume access is via an authenticated user.
776 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
777 key. When a change occurs mark the root.afs data as invalid and
778 for it to be reloaded on the next access. This allows administrators
779 to modify the mount point list without restarting the service.
781 The freelance client used to provide a fake modification time for
782 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
783 Added code to extract the last modification time of the Freelance
784 registry key and use that instead. The time now represents the
785 most recent mount point change.
787 * PTS registration of new users to foreign cells has been added to
790 * Additional Cache Control and Credential Manager options have been
791 added to the WiX installer. See deployment guide for details.
793 * The CachePath setting is now optionally a REG_EXPAND_SZ type
795 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
798 * The loopback installation code may have had a problem updating the
799 %ETC%\HOSTS file which could have resulted in a premature failure.
800 Work around code has been added for the case where the file cannot
803 * The default max chunksize was increased from 15 (32K) to 17 (128K)
804 because Windows sends 64K blocks when using overlapped writes.
806 * The default number of server threads was increased from 4 to 25 to
807 better handle overlapped writes.
809 * The "AfscredsShortcutParams" registry value was not being properly
810 loaded by afscreds.exe. Therefore, the default value was always being
811 used instead of the value set by the installer.
813 * Windows XP provides downgrade attack detection to prevent an attacker
814 from being able to force the use of NTLM simply by disrupting
815 communication with the KDC. This attack cannot exist between the
816 Windows CIFS client and the AFS Client Service. Therefore, when a
817 downgrade has been detected the afs pioctl library will force the
818 establishment of a new CIFS connection using NTLM.
820 * A locking error was discovered surrounding all references to volume
821 server lists within the cm_cell.c source file.
823 * The logged into Windows username was incorrect on Terminal Server
826 * A new registry value "NonPersistentCaching" was added to the service
827 parameters key. When set to a non-zero value, the afs cache is stored
828 in the Windows paging file. There are two limitations to choosing
830 1. when persistent caching is implemented it won't work with
831 this flag set since there will be nothing to persist.
832 2. with this flag set the initial paging allocation cannot be
833 changed while the service is running
835 * An initialization bug was discovered in aklog.exe which affected users
836 who have a domain name for their afs servers which could not be mapped
840 * afs_config.exe now validates cell names against DNS in addition
841 to the CellServDB file.
843 * In order to allow the freelance client to connect to a volume with ID
844 equal to 1 on the default cell we changed the fake root.afs volume ID
845 once again. This time we choose 0xFFFFFFFF. In addition, we change
846 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
847 It will now be impossible for a volume ID to match that of another
848 cell unless the client is connected to 0xFFFFFFFD cells. That should
849 be enough room for growth.
851 * Fix "fs mkmount" command to work with UNC paths and when
852 started from non-AFS drives. It is now possible to create a mount
853 point in the freelance fake root.afs volume with the command
855 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
859 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
860 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
862 * The algorithm used to re-attempt access to the servers associated with
863 a volume has been altered to properly address the case in which all
864 servers have been marked down. The previous algorithm did not reset
865 the server's down flags so the servers were never actually retried.
866 This caused a problem with active volumes if the network connectivity
867 was lost as could be the case with a network cable removal, wireless
868 drop, or laptop hibernation. With the fix volume access is restored
869 almost instantenously when network connectivity becomes available.
871 * Support for SMB/CIFS browsing has been added to the AFS Client Service
872 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
873 listing of AFS submounts and freelance mount points. Support for
874 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
875 significantly enhances the behavior of AFS volumes within the Explorer
876 Shell. For instance, "AFS" now shows up as server in the Explorer
877 with each submount or freelance mount point visible as a share.
878 The right click menu in each folder now works with full functionality
879 on a consistent basis.
881 * The network provider can be configured to have different behavior
882 depending on the domain that the user logs into. These settings are
883 only relevant when using integrated login. A domain refers to an
884 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
885 local machine (i.e. local account logins). The domain name that is
886 used for selecting the domain would be the domain that is passed into
887 the NPLogonNotify function of the network provider. (see registry.txt
890 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
891 "Authentication Cell" which may be used to specify a default
892 authentication cell for afscreds.exe which is different from
893 the default cell for the AFS Client Service daemon.
895 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
896 afslogon.dll moved to %WINDIR%\System32\.
897 New registry entries added to register the dll for Winlogon events.
899 The logoff event will now force a call to ktc_ForgetAllTokens()
900 using the context of the user being logged off as long as the
901 user's profile is not loaded from within AFS. If the profile
902 was loaded from AFS we can't release the tokens since the Logoff
903 event is triggered prior to the profile being written back to
904 the its source location. This is now performed in an XP SP2
907 * Windows XP SP2 Internet Connection Firewall interoperability
910 * The %WINDIR%\afsdsbmt.ini contains four sections:
911 Submounts, Drive Mappings, Active Maps and CSC Policies.
912 The Submounts and CSC policies are now stored in the registry under
913 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
914 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
915 The Drive Mappings and Active Maps are stored in the registry under
916 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
917 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
919 There is no automatic migration of this data as it would be impossible
920 to consistently migrate data to user profiles which may not be active
921 when the machine is updated.
923 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
924 fake root.afs volume. For the same reasons as for the cellservdb file,
925 this information should not be in %WINDIR%. This information is now
926 kept under the registry key
927 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
929 The data from the afs_freelance.ini file will be automatically
930 migrated to the registry on first execution of afsd_service.exe
932 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
933 troublesome for several reasons. One, it is confusing for those who
934 expect the file to be named "CellServDB" instead of "afsdcell.ini".
935 Two, this file is not a Windows Profile formatted file. Three,
936 applications should not be reading or writing to %WINDIR%. It causes
937 problems for Windows Terminal Server.
939 The new location of CellServDB will be the OpenAFS Client install
940 directory which is by default C:\Program Files\OpenAFS\Client and can
941 be determined by querying the registry for
942 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
944 The existing afsdcell.ini will be migrated by the NSIS installer.
945 The Wix installer must still be updated to do the same.
947 * Change NSIS installer to use DNS by default; to remove Integrated Logon
948 High Security mode; and to add Terminal Services compatibility registry
949 entries to allow the OpenAFS tools to find the afsdcell.ini and other
950 configuration files in %WINDIR%.
952 * Add support for authenticated SMB connections. This will remove
953 the need for high security mode in most situations. Both NTLM
954 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
955 only NTLM can be used even though Kerberos is now supported. The
956 reason is that it is not possible to construct a service principal
957 which is unique to each individual machine.
959 SMB Extended Auth does not work on XP SP2 unless one of two registry
960 modifications are made:
962 (1) To disable the check for matching host names on loopback connections
963 set this key. This does not require a reboot:
965 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
966 "DisableLoopbackCheck"=dword:00000001
968 (2) To add the AFS SMB/CIFS service name to an approved list. This
969 does require a reboot:
971 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
972 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
974 afsd_service.exe will automatically add the current Netbios Name
975 to the BackConnectionHostNames list and then temporarily disable
976 the loopback check for one cycle of startup/shutdown of the service.
977 We assume most folks do not start/stop without a reboot so this
978 will be adequate in most cases.
980 * Fix security hole in afslogon.dll which allowed passwords to be
981 sent in clear text to the KDC in a misformed principal name.
983 * Fix cm_GetCell() to properly handle expired dns entries
986 * If Freelance mode is active and the afs_freelance.ini
987 file does not exist, do not create an empty file.
988 Instead create a file containing ro and rw mountpoints
989 to the default cell using the standard conventions.
991 * Modify the Freelance support to handle the ability
992 to create rw mount points in the fake root.afs volume.
994 * Changed the RPC mechanism used for token setting from
995 named pipes to local. Use of named pipes can be restored
996 by setting the environment variable AFS_RPC_PROTSEQ to
999 Named pipes were required when a Windows 9x system was
1000 using a NT system in gateway mode which is incompatible
1001 with our use of local loopback adapters.
1003 * In afscreds.exe, if a username of the form user@REALM is
1004 specified and no password is specified, do not perform a
1005 kinit operation. Only perform the aklog functionality.
1007 * Add a new registry value which allows the number of processors
1008 on which afsd_service.exe executes to be restricted. Valid
1009 values are 1..numOfProcessors
1011 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
1015 * A second MSI based installer option is now available.
1017 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
1018 request tickets for user/instance@REALM instead of just user@REALM
1020 * Modify the Power Management Notify routine to wait for the Hard Dead
1021 timeout period instead of a fixed 19 seconds. With the longer timeout
1022 periods Hibernation and Standby could never succeed when network
1023 connectivity is not available.
1025 * The following fs.exe commands are now restricted to Administrator:
1026 - checkservers with a non-zero timer value
1029 - sysname with a new sysname list
1038 setting the default sysname for a machine should be done via the
1039 registry and not via "fs sysname".
1041 * NSIS installer adds options to install Debugging Symbols
1042 and the Microsoft Loopback Adapter; the user is now also
1043 given the ability to select the afscreds.exe startup options.
1045 * Build system modified to generate symbols for FREE (aka RELEASE)
1046 builds as well as CHECKED (aka DEBUG) builds
1048 * Sites which have a volume ID of 0x20000001 assigned to their
1049 root.cell volumes have been experiencing problems with accessing
1050 the root.cell volume of their cell when Freelance mode has been
1051 active. This was because 0x20000001 was assigned to the fake
1052 root.afs volume created by freelance. The fake volume id is
1053 now set to 0x00000001 to prevent conflicts.
1055 * The timeout logic in the AFS Client Service has been wrong
1056 for sometime. It is based on two different assumptions.
1057 First, the SMB client timeout is a fix value as was the case
1058 with OS/2 Lan Manager. This assumption is incorrect. The
1059 SMB timeout in Windows is a dynamic value computed based upon
1060 a fixed minimum timeout to which is added time based upon the
1061 size of the request and the performance characteristics of
1062 the connection. Second, it is the responsibility of the
1063 SMB Server to enforce the timeout requirements of the client.
1064 This is untrue. The SMB Server cannot be expected to know
1065 the requirements of the client. More importantly, if the
1066 SMB server uses the SMB client timeout as a value to restrict
1067 its behavior as an RX client, the performance characteristics
1068 of the local SMB session would be used to prematurely terminate
1069 WAN connections with significantly different performance
1072 The timeout logic has therefore been modified in the following
1074 . the Lan Manager Workstation (SMB) Session Timeout is used only
1075 as a basis for configuring the Connection Dead Timeout
1076 and Hard Dead Timeout values. The Connection Dead Timeout
1077 must be at least 15 seconds longer than the SMB Timeout
1078 and the Hard Dead Timeout must be at least double the
1079 Connection Dead Timeout.
1080 . New registry entries have been added to allow the Connection
1081 Dead Timeout and Hard Dead Timeout values independent of the
1082 Lan Manager Workstation Session Timeout
1083 . The test to enforce the SMB Client Timeout has been removed.
1085 One of the side-effects of removing the enforcement of the SMB
1086 Client Timeout is that regardless of whether or not the SMB client
1087 is available to receive the response (and how would the SMB server
1088 know) the RX protocol response can be used to update the AFS
1089 Client Service state for ready access by future SMB client
1092 This should be the end of the "Server paused or restarting messages"
1094 * Add support for arbitrary UNC paths to the pioctl() support.
1095 This enables the fs commands as well as the AFS Shell Extension
1096 to work correctly when UNC paths are being used.
1098 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1099 DNS if the cell configuration cannot be determined via CellServDB
1101 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1102 are ever set more than once at a time
1104 * Fix the management of lists of cm_cell_t structures when using
1105 DNS to lookup cell information. The previous code would fail to
1106 reuse the same cellID for a cell if DNS was used more than once
1107 for a given cell name. When the ttl expired, a single cm_cell_t
1108 could be inserted into the cm_allCellsp list more than once
1109 producing a loop. In addition, the vlServerp list belonging to
1110 the cell was not freed resulting in improper refCounting of the
1113 * Add DNS support to cm_IoctlNewCell() which previous only examined
1116 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1117 to properly garbage collect cm_server_t objects
1119 * Add numVCs variable to smb.c to track the number of smb_vc_t
1120 objects created and use it to initialize the vcID field which
1121 previously was set to 0 in all objects resulting in FindByID
1124 * Fixed DNS lookups to work consistently throughout the OpenAFS
1125 product instead of just from within the afsd_service.exe
1127 * Added a runtime check to ensure that AFS Client Service SMB
1128 Server is accepting connections before attempting to mount
1131 * Read IP addresses for volume servers out of the CellServDB
1132 file if gethostbyname() on the hostname fails.
1134 * Fix getcellconfig() to populate both the Hostnames as well
1135 as IP addresses when loading cell data via DNS
1137 * Increase the Connection Dead Time to 50 from 20 seconds
1138 Increase the Hard Dead Time to 120 from 40 seconds
1139 (matches the Unix values)
1141 * Fixed an assertion validating the number of allocated NCBs
1143 * Fixed the build environment to consistently build for
1144 Windows 2000 and above. (APPVER = 5.0)
1146 * Fixed rx_debug to properly validate the receipt in incoming
1147 data with select() and recvfrom(). Do not copy data out of
1148 the socket buffer unless success is indicated.
1151 * afsd_service.exe will now display a message box to the
1152 desktop when it terminates due to an IP Address Change.
1154 * installer no longer deletes AFS Server configuration data
1157 * installer generates a warning dialog if the RPC service
1158 is not properly configured
1160 * installer compressed with lzma instead of bzip2
1162 * afsd_service.exe shutdown crash solved once and for all
1164 * reference counting of smb_vc_t data structures improved
1166 * name space collision of smb_fid_t event objects corrected
1168 * the output of "fs memdump" is now written to
1169 %WINDIR%\TEMP\afsd_alloc.log
1171 * the file TaAfsApp_1033.dll is now properly installed allowing
1172 the User Manager to start
1174 * a new algorithm is used for computing filename pattern matches
1176 * afscreds.exe now accepts user names containing instance
1179 * Fix the Directory Name Lookup Cache to be case-sensitive.
1180 This is crucial in environments in which a Windows client
1181 is accessing a directory with more than one filename that
1182 differs only by case. If the directory contains "FOO"
1183 and "Foo". You want "DEL Foo" to delete the correct one.
1184 We still have a problem in that "DEL foo" will delete a
1185 random filename. This will be addressed in a future release.
1187 * Fix afscreds.exe -M option (renewMaps) to work when High
1188 Security mode is off. Also, remember to disable the ActiveMap
1189 flag in afsdsbmt.ini when a drive mapping is removed.
1191 * Updates to NSIS installer script. AFS Server configuration
1192 data will not be destroyed on un-install or re-install.
1193 Use a better compression algorithm.
1195 * afslogon.dll now uses KFW to obtain tokens when available
1197 * afslogon.dll when given an all uppercase username will
1198 attempt to authenticate with both the uppercase name
1199 and an all lowercase variation
1201 * DST modification removed. The fix appears to make things
1202 worse after a reboot of the machine.
1204 * fs.exe: added "cscpolicy" which is used to
1205 change client side caching policy for AFS shares
1207 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1208 [-documents] [-disable] [-help]
1210 * Several uninitialized variables have been initialized
1212 * It is now possible to obtain tokens using cross realm
1213 Kerberos within afscreds.exe:
1215 user: jaltman@ATHENA.MIT.EDU
1217 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1218 will will in turn be used to obtain afs@DEMENTIA.ORG.
1219 The resulting token will be stored with the display name
1220 jaltman@ATHENA.MIT.EDU@dementia.org
1222 * aklog.exe has been added to the client
1224 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1225 [[-p | -path] pathname]
1229 -d gives debugging information.
1230 krb_realm is the kerberos realm of a cell.
1231 pathname is the name of a directory to which you wish to authenticate.
1232 -noprdb means don't try to determine AFS ID.
1233 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1234 (default is Kerberos V)
1235 No commandline arguments means authenticate to the local cell.
1238 * All of the resource files have been restructured to adhere to
1239 a set of rules IBM implemented for loading string resources.
1240 These rules had either been forgotten or were not discovered
1241 by folks working on the OpenAFS sources. The end result was
1242 memory corruption. This is primary item which was preventing
1243 the AFS Server from working.
1245 * Increased the size of the maximum ticket size stored in a token
1246 from 344 bytes to 12,000. Increased the buffers used to convey
1247 messages between the pioctl() caller and the SMB Server from
1248 1000 bytes to 12,512. The code appeared to have been writing
1249 above the top of the stack by quite a few number of bytes.
1250 (The increased ticket size is necessary for the next item.)
1252 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1253 Instead the raw Kerberos 5 ticket is used in its entirety. This
1254 is extremely important as it allows us to use pure Kerberos 5 KDCs
1255 as the source of the AFS authentication. The use of up to 12,000 byte
1256 tickets will allow tickets produced by all versions of Microsoft
1257 Active Directory to be used.
1258 - create a user account.
1259 - designate it DES only
1261 - specify its UPN to be "afs@realm"
1262 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1264 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1265 is special when using long file names. (you must use "*.*" and not "*")
1266 Instead only enforce it when performing 8dot3 searches.
1268 * Fixed the DST problem with creation times being set one hour ahead
1270 * Fixed the problem when using \\afs\cell-alias. For example,
1271 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1272 for the alias name; instead simply expand the name. One of the
1273 symptoms of this problem was a loss of acquired tokens.
1275 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1276 of strings. (Only English strings provided.)
1278 * Fixed the installer to properly replace in use files.
1280 * Fixed the build system to cleanup generated component version files
1282 * The release build compiled with MSVC 6.0 compiler to avoid the
1283 afsd_service.exe shutdown crash. This does not solve the problem
1284 but simply avoids it for the time being.
1288 * fix afslogon.dll to not corrupt memory when High Security mode
1291 * fix afsd_service.exe to not attempt to restore the stack when
1292 an exception occurs. (not safe in multi-threaded programs)
1294 * fix uninstaller to properly remove the CRT and MFC DLLs
1296 * remove a Message Box from afscreds.exe when getcellconfig()
1297 fails on a kerberos realm which is not a cell
1299 The following is a list of changes to the OpenAFS for Window client
1302 * "fs setserverprefs" will leave afsd service deadlocked
1304 * "vos listaddrs" will core dump
1306 * installer sets the appropriate keys to support Integrated Logon
1308 * installer disables the "Find Lana by Name" functionality as it
1309 was causing headaches for many users
1311 * fix the intermittent crash of the power management thread when
1312 shutting down the AFS Client Service
1314 * optimizes the obtain drive mount list functionality which is
1315 executed every time the mount tab in afscreds.exe and afs_config.exe
1316 are refreshed. (this happens a lot)
1318 * fix the service shutdown logic. add the STOP_PENDING state
1319 and do not accept additional service events after we declare
1322 The following is a list of changes to the OpenAFS for Window client
1325 * flexelint was run against the source tree and hundreds (perhaps
1326 thousands) of corrections were applied to ensure prototypes
1327 were in use; types were used consistently; variables were
1328 initialized; unused variables were removed; etc.
1330 * A wide variety of instrumentation was added including the
1331 ability to produce a stack trace from within afsd_service.exe
1334 * Dynamic configuration of the RDRtimeout value based upon the
1335 LanMan Workstation Session Timeout
1337 * The mount root no longer needs to be called "/afs". This
1338 is now set by a registry value "MountRoot" within the key
1339 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1341 * The cell list is now only read out of afsdcell.ini when the
1342 file changes instead of each time a cell is resolved.
1344 * Thread synchronization was added to cm_server.c and ktc_nt.c
1346 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1347 calloc()/free(). The Global functions were needed on Windows 3.x
1348 but have caused a variety of problems on the Win32 platforms.
1349 Avoiding them is highly recommended by several Microsoft
1350 Knowledgebase articles
1352 * Support for Symbolic Links added to the AFS Shell Extension
1354 * Added a registry value "OverlayEnabled" to determine if
1355 Shell Extension Overlays should be enabled.
1356 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1358 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1359 separate trees for checked and free builds. Build system supports
1360 a custom directory src\WINNT\extra which can be used as a grafting
1361 location of organization specific additions to the build tree.
1363 * New installer built using NSIS 2.0.
1365 * Named all kernel objects in order to allow them to be monitored
1366 with tools such as SysInternals' ProcExp.exe.
1368 * Introduced new EventLog framework for AFSD
1370 * Introduced Power Management interface to AFSD for Standby and
1371 Hibernate modes to allow cache to be flushed prior to network
1374 * Utilize Win32 DNSQuery API instead of internal routines. This
1375 allows DNS SRV queries to be sent to all current domain name
1376 servers. Not just one specified in an INI file. DNS is now
1379 * "NetbiosName" registry value may be used to specify a fixed
1380 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1381 when the loopback adapter is in use. If you need to use the
1382 old notation with a loopback adapter installed specify a registry
1385 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1387 * Refactor all modules which depend on LAN Adapter and NetbiosName
1388 determination in a new library: lanahelper.lib. This allows for
1389 consistent behavior throughout the product.
1391 * Move the afsd.log and afsd_init.log files to the directory specified
1392 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1393 for services. Added the Date to the log entries.
1395 * New registry value "RxMaxMTU" used to limit the size of the RX
1396 packets sent by the AFS Client Service to the Server. In order
1397 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1398 size must be restricted to 1264 or smaller. The latest NSIS
1399 installer sets a value of 1260 by default.
1401 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1402 packets. This is not needed in order to work across the Cisco
1403 VPN but might be needed for other network environments. This
1404 value is not set by the NSIS installer.
1406 * New registry value "HideDotFiles" is used to apply the Hidden
1407 attribute to files whose names begin with a '.'. This value
1408 is set by the NSIS installer.
1410 * New registry value "MaxMpxRequests" allows the maximum number
1411 of multiplexed sessions to be configured at run time. This
1412 value is not set by the NSIS installer. The default value is
1415 * New registry value "MaxVCPerServer" allows the maxmimum number
1416 of VCs per server to be configured at run time. This value is
1417 not set by the NSIS installer. The default value is 100.
1419 * New registry value "AllSubmount" allows the "all" submount to
1420 be disabled by setting its value to 0x00.
1422 * Allow cells names to be valid mount points
1423 \\<netbiosName>\<cellname>
1425 * Store the active state of drive mappings in order for afscreds.exe
1426 to restore them upon startup
1428 * Add exception handling to generate a Stack Trace to the afsd_init.log
1429 file if one happens to occur.
1431 * Add lots of logging to help detect the cause of invalid SMB packets
1433 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1434 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1435 renewal of expiring tokens as long as afscreds.exe is running.
1437 * New afscreds.exe command line options:
1439 -M = renew drive maps
1440 -N = ip address change detection
1443 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1444 determines whether or not MIT Kerberos for Windows should be used
1445 to obtain tokens via Kerberos 5 tickets.
1447 * New registry value "AfscredsShortcutParams" in
1448 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1449 determines the command line parameters to be specified when "fixing"
1450 the AFS Shortcut in the user's startup folder.
1452 * The "ShowTrayIcon" registry value has been moved from
1453 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1454 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1456 * The <cell name> registry values used to store the token expiration
1457 reminders have been moved from
1458 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1459 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1461 * Obtain the Logon User Name from the Explorer key when available
1463 * new text document doc\txt\winnotes\registry.txt lists all registry
1464 values used by OpenAFS (excluding the AFS Server)
1466 * BUG: rx_securityClass objects were not properly reference
1467 counted and were never freed.
1469 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1470 would be generated. The existence of a server does not imply
1471 that it is not down. If all of the servers for a cell are down
1472 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1475 * BUG: the directory name lookup cache failed to free the entries
1476 in the cache when the name cache entries cycled. The entries
1477 in the cache would become dereferenced without being freed.
1479 * BUG: fs setserverprefs could be executed without Administrator
1482 * BUG: the number of allocated NCB objects (100) exceeded the number
1483 which could actually be waited upon by the kernel (64). Any objects
1484 which were utilized above the limit could never have event completions
1487 * BUG: smb_username_t objects were not being reference counted and
1488 were not properly freed.
1490 * BUG: smb_tid_t objects could under unusual circumstances be freed
1491 before they were no longer referenced.
1493 * BUG: smb_fid_t object pointer were frequently used even when
1494 their value could be NULL. They were not properly released and
1495 therefore they were never freed.
1497 * BUG: smb_packet_t data structures were not completely initialized
1500 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1501 Denied" because that causes the Explorer Shell to try again until
1502 access is obtained. Instead return "Remote Resources" which allows
1503 the shell to move on and treat the error as transient.
1505 * BUG: when initializing the NCBreturns structure, separate Event objects
1506 were created for each NCB although a single Event object was supposed
1507 to be shared by all.
1509 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1512 * BUG: smb_tran2Packet_t objects were not being properly referenced
1515 * BUG: directory path creation did not handle the case of multiple
1516 directories requiring creation in one attempt
1518 * BUG: SMB requests which required an Extended Response were ignored.
1519 This prevented some files from being written to AFS volumes.
1521 * BUG: character strings were being freed even after they were
1522 inserted into in use data structures
1524 * BUG: inconsistent usernames were used when High Security mode was
1525 enabled. (there is still much to do in this area)
1527 * BUG: pioctl() calls which require out of band RPC operations were
1528 susceptible to race conditions when performed by multiple processes
1530 * BUG: memory allocation and deallocation crossed instances of the
1531 C Runtime Library producing memory leakage and corruption in
1532 afscreds and the client configurator.
