2 * Optimize calls to cm_CheckServer from cm_Analyze. Only check
3 down servers for the current cell not all cells.
5 * If the scache LRU list becomes corrupted, the AFS Client Service
6 might enter an infinite loop at startup. Detect the corruption
7 and discard the cache contents in this case.
9 * Fixed the Explorer Shell's remove mountpoint functionality.
11 * Fixed a deadlock caused by the holder of cm_aclLock attempting to
12 obtain a mutex lock on a cm_scache_t object whose lock is held by
13 a thread attempting to obtain the cm_aclLock.
16 * Really fixed DNS AFSDB queries to ensure that "csail" cannot be
17 misinterpretted as "csail.mit.edu" when the resolver
18 is configured to append ".mit.edu" to failed DNS queries.
20 * Added a new registry key, "LogoffPreserveTokens" (see registry.txt),
21 that can be used to force the preservation of user tokens upon logout.
23 * Update the NSIS install scripts to use NSIS 2.07. This release adds
24 recommended installation categories: AFS Client, AFS Administrator,
25 AFS Server, AFS Development Kit. Each category includes a different
26 default subset of the OpenAFS components.
28 The OpenAFS logo is now associated with the NSIS uninstall entry
29 in the Add/Remove Programs control panel.
31 * The user name associated with AFS tokens when obtained with
32 integrated login, the afs systray tool, or aklog will always
33 include the full Kerberos 5 user principal name regardless of
34 whether or not the cell is local to the realm.
36 * Eric William's IFS redirector has been checked onto the CVS head.
37 This code is experimental at the current time and is not being
38 incorporated into the 1-4 branch releases. Instructions for
39 building from sources are found in the top-level README-NT file.
41 * Modify integrated login so that it does not enter an infinite
42 loop if the service is not set to auto start.
44 * Added asetkey.exe used to set a Kerberos 5 key for use by the
47 * Added uninstall.exe to Wix installation
49 * More modifications to algorithms used to wake sleeping threads.
53 * Changes to the algorithms used to wake threads when they are
54 put to sleep because of conflicts over buffer operations.
57 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
58 the process of producing AFS tokens. The tokens are stored within
59 the AFS Client Service but the Kerberos 5 tickets have been discarded.
60 New functionality has been added to temporarily copy the tickets to
61 a file ccache during the short window between the NPLogonNotify and
62 WinLogon Logon Event. The Logon Event handler starts a process as
63 user, afscpcc.exe, that copies the tickets into the default ccache.
64 The file ccache is then destroyed by the event handler.
66 * During synchronization operations on stat cache entries, if threads
67 are forced to sleep it was possible that the threads would not be
68 woken under heavy load.
70 * Enforce the delete on close flag specified by the NTCreateX()
73 * A race condition in the rx library was fixed that resulted in
74 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
75 was cleared when threads were still waiting to use the
76 connection. Also, fixed a potential case in which the
77 connection could be destroyed while threads were waiting to use it.
79 * The DNLC freelist has been seen to become corrupted with still
80 active entries being stored on the freelist. Changes were made
81 to perform a better job of cleaning entries before placing them
82 onto the freelist; marking them with the correct magic value when
83 purging the list; and allowing the list to be purged on startup
84 if the cache validation fails.
86 * Windows Crash Reporting does not get triggered for afsd_service.exe
87 because it provides its own top level exception handler. This patch
88 places an explicit call to ReportCrash() on platforms which support
91 If you configure Crash Reporting via AD Policy to capture crash
92 reports within the domain, then you will receive this output.
94 * Generate MiniDumps independent of the Windows Crash Reporting.
96 (a) If an exception occurs,a minidump will be generated at the path
97 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
98 can be set to any other type via use of the
101 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
103 (b) MiniDumps can be generated at any time using the "fs minidump"
104 command. This allows you to generate a minidump without
105 stopping the process or even requiring the use of a debugger
108 * an RX connection which reports bad ticket now treats it the same way
109 the expired ticket is treated. The ticket is removed from the
110 connection and a new anonymous connection is established.
112 * fs memdump now requires that the caller be in the AFS Client Admins
115 * additional debugging information is provided in cm_Analyze when the
116 error code is ignored.
118 * Fix a regression introduced into the pioctl() client code which
119 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
120 MIT KFW is not installed. (1.3.82a)
122 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
125 * Fix a race condition in cm_EndCallbackGrantingCall() that
126 could leave 'nrevp' pointing to freed memory. In the process,
127 optimize the processing to ensure that the applications monitoring
128 the status of the stat cache entry are only notified at most
131 * Conditionalize access to the Explorer Shell AFS->Mount Point
132 ->Remove menu item. Disable the item if the selected item(s)
133 are not mount points.
135 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
136 Local Storage. This eliminates thread contention on the
137 global RX free packet queue. This should improve performance
138 on multi-CPU systems.
140 * Fix the IP address filtering code to properly load/unload
141 the IPHelper DLL so that Windows XP/2003 and beyond systems
142 do not have to manually probe the registry.
144 * CleanupACLEnt() was not being called consistently with
145 the cm_scache_t object referred to by the back pointer
146 mutex locked. This could in very rare conditions lead to
147 an invalid memory access.
149 * Added a script command to the msi installer "afs_replace"
150 which can be used to replace one version of OpenAFS with
151 another without requiring an uninstall and reinstall if
152 the installed msi is no longer in its original location.
154 * Apparently the problem with multi-domain forests with cross-
155 realm trusts to non-Windows realms was not entirely solved.
156 The authentication to the AFS SMB service failed because
157 the wrong name was being used. Using ASU as an example,
158 the authentication was being performed with the name
159 "QAAD\user" (an account in the forest root) and not
160 "user@ASU.EDU (the MIT Kerberos principal used to login with)
162 The solution was to add an additional dependency on KFW
163 in order or to be able to easily obtain the client principal
164 name stored in the MSLSA ccache TGT. This information is
165 used in two locations:
167 - the pioctl() function
169 - a new WinLogon Event Handler for the "logon" event.
171 The pioctl function will now be able to use the correct
172 name when calling WNetAddConnection2() and the "logon"
173 event handler will now be able to call WNetAddConnection2().
174 The hope is that the "logon" event handler will be called
175 before the profile is loaded but I have not guarrantee
179 * Fixed a locking error in cm_TryBulkStat() which had the
180 potential of deadlocking the system for the length of time
181 it takes to perform a bulk status fetch operation.
183 * Replaced time conversion code (UnixTime <-> FILETIME) to
184 be completely arithmetic instead of relying on a bizarre
185 algorithm involving a variety of C RTL time functions.
186 This has the side effect that UnixTime and FILETIME which
187 are both stored in UTC are interpretted as UTC throughout
188 the year. Windows will apply the same localization to AFS
189 as it does to NTFS. Applications which rely on the ability
190 to sync files between the two file systems will no longer
191 see the timestamps of files in AFS change an hour relative
192 to the files stored in NTFS or Windows based backup devices.
194 * Fixed a invalid memory access under a bizarre circumstance.
195 Windows will allow a physical mass media device to be
196 installed via Plug N Play to the system and will assign it
197 the lowest available drive letter. This is true even if the
198 drive letter is currently assigned in the user session to
199 a network device via NET USE (or its equivalent.) When this
200 happens, queries sent to the CIFS server will contain invalid
201 data. This invalid data was not being caught by the AFS
202 Client Service and was resulting in a crash when Freelance
205 * Fixed a reference count error when registering callbacks
206 on a stat cache object if the callback was already registered
208 * Add a case to cm_Analyze() in order to handle the case where
209 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
210 the server list for the volume is empty. In this case, force
211 an update of the volume info and retry.
213 * Insert a missing cm_EndCallbackGrantingCall() which could
214 result in threads waiting for a callback to complete to never
217 * In the persistent cache, there is a maximum number of volume
218 entries. Allow volume entries to be reused if the maximum
219 number have been allocated and their reference count is zero.
221 * If we already have a dead virtual connection object, don't
222 ignore the fact that additional dead vc objects must be taken
225 * Removed a deadlock condition introduced in the summer of 2004.
226 Do not hold mx locks around calls to RX functions including
227 rx_NewCall(). That is what reference counts on the rx_connection
230 * Fixed an initialization error in afslogon.dll which could
231 result in random behavior including a failure to terminate
232 the NPLogon function. (1.3.80b)
234 * Fixed an error preventing the use of SMB authentication
235 on Windows 2000. (1.3.80a)
238 * Updated CellServDB to Public CellServDB 16 Mar 2005
240 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
241 misinterpretted as "csail.mit.edu" when the resolver
242 is configured to append ".mit.edu" to failed DNS queries.
244 * Fixed another case in which the client would replace connections
245 to the host when it was not necessary. In this case the
246 situation would occur if cryptall was on and the connections
247 were unauthenticated due to lack of an appropriate token.
249 * OpenAFS for Windows has failed to work at sites which are
250 utilizing a cross-realm trust between an MIT/Heimdal realm
251 and a multi-domain Windows forest when the workstation being
252 accessed is not located in the root domain. This is caused
253 by a bug in the workstation which was triggered after the
254 introduction of Windows 2003 Server. When the bug is triggered,
255 the workstation attempts to authenticate users to afsd_service.exe
256 by contacting the Domain Controller instead of using the
257 LSA loopback authentication mechanism.
259 One of the reasons this bug occurs is because the workstation
260 does not have a reliable way of knowing that the service whose
261 netbios name is "AFS" is located on the workstation. This will
262 be fixed starting in Longhorn Beta 1 by Microsoft. The
263 "BackConnectionHostNames" registry value will be used to
264 indicate that the authentications to that service name should
265 be performed using the loopback authentication mechanism.
267 In the meantime, when Logon Caching is enabled, we can force
268 afsd_service.exe to authenticate using the logon cache before
269 contacting the Domain Controller. This will work with both
270 password and smart card based logons.
272 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
273 flag should not be cleared if a volume's server reference is
274 marked as "offline". In the case where all of the volume's
275 servers are either "down" or the volumes are "offline", we want
276 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
277 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
278 should never occur in practice.
280 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
281 5 seconds, clear the server down and volume busy flags, and
282 then force an update from the VLDB. This allows the client to
283 update the location of a volume if the reason for it being
284 marked offline is because it is being moved. Calls to
285 cm_ConnByMServers() will be retried either until success or
286 the RDRtimeout period is reached.
288 * Correct the Power Management code behavior in response to
289 Standby, Suspend, and Shutdown events. Instead of flushing the
290 buffers associated with the mounted SMB submounts, simply write
291 all buffers which are marked dirty.
293 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
294 provides a list of cells other than the default cell for which
295 tokens should be obtained using the default Kerberos principal.
296 This functionality is logon domain specific and is only available
297 when using KFW for authentication.
299 * Fixed FindNext Invalid Handle error caused by over agressive
300 attempts at garbage collecting dirSearch entries when the
301 dirSearch ID wraps from the maximum value to 1.
303 * Add support for registry defined server preferences for VLDB and
304 File servers. See registry.txt for details.
306 * Increased default cache size to 96MB and default number of cache
309 * Fixed refCount leaks related to directory lookups and pioctl calls.
311 * Callbacks revoked during a race condition with an attempt to
312 obtain the same callback no longer result in an inaccessible
315 * New command line tool:
317 afsdacl : Set or reset the DACL to allow starting or stopping
318 the afsd service by any ordinary user.
320 Usage : afsdacl [-set | -reset] [-show]
322 -reset : Reset the DACL
323 -show : Show current DACL (SDSF)
325 * IP addresses are no longer queried once at startup. Instead IP
326 addresses are obtained as needed. Loopback adapter addresses are
327 no longer published to the server.
329 * Pay attention to the MIT KFW registry configuration for automatic
330 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
332 * Fix (once again) case-sensitive comparisons which was apparently
335 * Activate support for vos listvol -format
337 * Population of the "AFS Client Admins" group failed on non-English
338 versions of Windows because the name of the "Administrators" group
339 is localized. Now we lookup the name of the group by using the
340 Administrators Group Alias Relative ID.
342 * Multiple cell token acquisition within afscreds.exe was broken in the
343 case of Kerberos 5 cross realm authentication. Instead of contacting
344 the KDC associated with the cell's realm, afscreds would obtain a
345 token from the KDC of the user's realm. This would result in
346 "invalid kvno errors" while authenticating to the AFS servers.
347 Unauthenticated access would work. The symptoms would vary based upon
348 whether or not the VLDB servers had been contacted using unauthenticated
349 connections prior to the user obtaining tokens.
351 * The list of ACL entries was becoming corrupted. It appears as if
352 an ACL when it expires was not being appropriately cleaned up. In
353 fact, it was left in the list of ACLs associated with the scache
356 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
357 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
358 and "amd64_win64" for amd 64-bit processors.
360 * When executing executables, Windows provides a mechanisms by which
361 the normal search for DLLs can be bypassed. If a file foo.exe is
362 being executed and there exists a file or directory "foo.exe.local"
363 (the contents are ignored if a file), then Windows will search for
364 DLLs first in the "foo.exe.local" directory and second in the
365 directory in which the "foo.exe" file is located.
367 Previous releases of OAFW would improperly return
368 STATUS_NOT_A_DIRECTORY instead of the expected
369 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
370 to terminate the search for the DLL causing the execution of the
373 * Rework the reference counting of smb_vc_t objects. The references
374 stored in the waiting locks were not counted. This could result in
375 an assertion if the reference count drops to zero.
377 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
378 when running in freelance mode.
380 * Added support for persistent caching of file contents, stat entries,
381 volume data, cell data, and name lookup data. When the registry
382 value, "NonPersistentCaching", is not defined or set to 0 the file
383 specified by "CachePath" becomes a persistent cache file. The
384 size of the cache file is computed at run time. It has a maximum
385 size of approximately 1.2GB. The contents of the file will be
386 validated according to the rules specified by the "ValidateCache"
389 * Added support for UUIDs. UUIDs are kept for as long as the
390 cache file is intact.
392 * Added cmdebug.exe and support cache manager debugging callback
393 interfaces in afsd_service.exe.
395 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
396 [-addrs] [-cache] [-help]
397 Where: -long print all info
398 -addrs print only host interfaces
399 -cache print only cache configuration
401 * Symlinks to \\AFS\[all\]... will now be treated the same as
402 symlinks to /afs/.... However, please use /afs/... as otherwise
403 the symlinks won't work on Unix.
405 * Correct a problem with local CellID allocation for cells whose
406 server list is obtained via DNS instead of a CellServDB file. If
407 the DNS information expires the CellID assigned to the entry will
408 be changed. This causes all of the cm_scache_t objects which refer
409 to the old cellID number to become useless. Attempts to access
410 files or directories with cm_scache_t objects using the old cellID
411 will fail since the server list cannot be obtained.
413 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
414 be triggered if the volume referenced by the cm_scache_t object is
417 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
418 in addition to SERVICE_ACCEPT_STOP.
420 * Move RPC shutdown until after the SMB and RX shutdown procedures
421 complete. Block until RPC shutdown is complete.
423 * Modify afslogon.dll (integrated logon) to wait for service if its
424 state is START_PENDING. If the timeout period occurs, reset to
425 the retry interval and not the sleep interval.
427 * When renewing the server list for a cell obtained via DNS AFSDB
428 records, the cm_cell_t entry must be removed from the list of all
429 cells. Otherwise, the list of cells will be corrupted.
431 * In the dcache and scache modules, use the cm_scache_t dataVersion
432 instead of the cm_fakeDirVersion.
434 * Synchronize fs.c with the unix version.
436 * The variable used to determine whether a file or virtual memory
437 mapped cache is used was not properly initialized to a default
438 value. If the registry setting "NonPersistentCaching" was not
439 set, the choice would be random. Properly initialized to be
442 * The memory mapped view was never unmapped before closing the file
443 at service shutdown. This is now properly cleaned up.
445 * Default location of Cache file is now %TEMP%\AFSCache
449 * A bug affecting new installations of 1.3.75/76 would result in
450 the creating of incorrect mountpoints in the freelance root.afs
451 volume for the default cell.
453 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
454 of "root.cell", you have been affected by the bug. To correct the
455 problem, execute the following commands:
457 fs rmmount \\afs\all\<cellname>
458 fs rmmount \\afs\all\.<cellname>
460 fs mkmount \\afs\all\<cellname> root.cell <cellname>
461 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
465 * A bug has been fixed in the auto-generation of Freelance root.afs
466 symlinks which produced random entries in the \\AFS\all directory.
468 * Support has been added for multi-homed servers
471 * Added a new registry value, "StoreAnsiFilenames", which can be used
472 to force the use of ANSI character sets instead of OEM Code Pages.
473 This feature is useful when users require the ability to create
474 filenames with 8-bit characters and need to access the files from
475 both Latin-1 based Unix systems as well as from Windows.
477 Activation of this feature will prevent access to files stored with
478 8-bit OEM characters.
480 * Shutdown all SMB threads in a synchronized manner when stopping the
483 * There is currently a maximum cache size of 1.3GB. The limit is imposed
484 by the largest contiguous block of unused memory within the 2GB process
485 space which can be assigned to the memory mapped file. Unfortunately,
486 when the executable digital signature verification code is activated
487 Windows sees fit to further segment the process memory which in turn
488 reduces the size of the maximum cache file to less then 800MB. If
489 larger cache sizes are desired, a new registry value should be set:
491 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
493 Setting this value will disable the runtime verification of digital
494 signatures on afsd_service.exe and the afs dlls which it loads. It
495 will not disable the the version number check on those same files.
496 The signature verification is not a security messure and is only meant
497 to enhance the ability to afsd_service.exe to detect potential
498 destablizing mixtures of DLLs from incompatible distributions.
500 Added code to auto-disable the signature verification check if
501 the desired cache size is greater then 700MB.
503 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
504 used to verify the validity of the afsd_service.exe binary
505 as well as each of the AFS DLLs loaded by the service. Not only
506 must the digital signature be valid but the signatures of the
507 DLL must be signed by the same entity as the service.
509 * Implement new functions: cm_freelanceMountPointExists and
510 cm_freelanceSymlinkExists. Use them along with other validity
511 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
512 ensure that name collisions do not occur and that empty strings
513 are not valid file names.
515 A symlink may not have a name which would resolve to a valid
516 cell name. Doing so would prevent access to the cell.
518 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
519 re-initialization code. The reference counts of the fake root.afs
520 volume scache object(s) would become invalid when the mount point
521 or symlink lists were altered.
523 * Add registry entries to provide mappings from the afsdsbmt.ini
524 to the new locations for applications which count on the use
525 of the old Profile file APIs. These apps are likely to fail
526 if the user does not have administrator privileges and the
527 registry is locked down.
529 * The afs_config.exe submounts dialog had two errors.
530 First, attempts to remove entries failed because the registry
531 key was being opened without KEY_WRITE privileges.
532 Second, when editing a submount entry, changing the name
533 would add a new key and leave the original one in place.
534 Now the original submount will be removed if its name is
537 * In recent months there have been several incidents in which
538 users have experienced problems starting or accessing
539 afsd_service.exe and after significant effort has been spent
540 it has turned out that they have two versions of AFS on the
541 machine or an inconsistent set of DLLs.
543 Code has now been added to afsd_service.exe which will walk
544 the list of modules loaded by afsd_service.exe and validate
545 that the version of the AFS DLLs matches the version of the
546 afsd_service.exe executable. If they do not match the service
549 * When Freelance mode is enabled and there is no registry
550 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
551 will attempt to import the afs_freelance.ini file contents.
552 If the file does not exist, it was creating a dummy file
553 with a r/o and r/w entry for the default cell and then
554 importing those values.
556 This process has been changed. The temporary file is no
557 longer created. Also, both the OpenAFS Client install
558 directory as well as %WINDIR% are checked for previous
559 afs_freelance.ini files.
561 * Added support for VL_GetEntryByNameN(). Still need to add
562 support for VL_GetEntryByNameU() for multi-homed support.
564 * Fix a deadlock situation in afscreds.exe when canceling an
565 auto-generated Obtain Tokens dialog
568 * Fix the locking of objects during Directory Searches in the
569 SMB/CIFS server. The failure to properly lock the reference
570 counts was resulting in the premature freeing of smb_dirSearch_t
571 objects while they were still in use by the SMB/CIFS client.
572 This does not solve the "Invalid Handle" problem.
574 * Fix Find Cell By Name pioctl call to return a valid cell
575 name for the Freelance fake root.afs volume.
576 "Freelance.Local.Root".
578 * Fix the Explorer Shell Extension Symlinks->Add operation.
579 The dialog template was missing and the link destination
580 string was too short.
582 * Add support for symlinks to Freelance root.afs volume
583 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
584 <number> = "<linkname>:<relative-path>."
585 Use symlink.exe to create, list, or remove
587 * Remove the fallback to the use of KFW's KRB4 library when obtaining
588 tokens. We never obtain KRB4 tickets.
590 * Fix AFS Client Configuration Control Panel to support new SysName
593 * Fix a bug in afsd_service.exe which could result in the SysName
594 not being read from the registry.
597 * Add code to block the issuance of AFS tokens by aklog.exe or
598 afscreds.exe when the Kerberos 5 principal name contains a dot.
600 * Modify the IsAdmin() function to always treat the local SYSTEM
601 account as an AFS client administrator. Affects fs.exe and
604 * Modify the internal handling of Quota Exceeded errors
606 * Upgrade all reference count fields in the Windows cache manager
607 and the osi library to use unsigned long instead of signed short.
608 A similar fix has been applied to the afs rpc (rx) library.
610 * fix the Windows cache manager to prevent it from replacing the
611 rx_connection object associated with the cm_conn_t object on each
612 and every operation if "fs crypt" was set. This explains the
613 dramatic performance difference when crypt is used vs clear.
614 The problem: 'cryptall', a boolean flag indicating whether or not
615 "fs crypt" is set, was being compared to the rx_connection
616 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
617 1 != 2 and therefore the rx_connection was always destroyed
618 and replaced on each and every operation.
620 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
621 It is not safe for the cm_conn_t object to not be locked because
622 rx_DestroyConnection might be called from another thread if:
623 - the user's tokens have changed or expired
624 - the crypt mode has changed
626 This fix appears to have also taken care of the problems associated
627 with Overlapped Writes resulting in Delayed Write errors.
629 * fix NSIS installer's AdminGroup.exe to properly create and
630 remove groups when given -create or -remove. The string comparison
633 * fs sysname now accepts a list of sysname values
635 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
636 DWORD which when set to a non-zero value will cause error message
637 text to be output to stderr from the pioctl() routine. Useful in
638 debugging failures of fs.exe, tokens.exe, etc.
640 * added a test to the power management code to only perform a
641 flush operation if there is at least one network adapter which
642 is not a loopback adapter.
644 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
645 "EnableKFW". This value will not be read if the key
646 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
647 value under that key does not.
649 * provide mechanisms to force the use of krb524d for Kerberos 5
650 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
651 there is a new registry value "Use524" and for aklog.exe a new
652 command line parameter "-m".
654 * Fix the pattern matching algorithm to properly match patterns
657 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
658 which is used by both the original function and the new
659 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
660 creation of HardLinks in addition to Renaming. smb_Link()
661 is a new function which creates HardLinks via cm_Link().
662 cm_Link() is a new vnodeops function which creates links
665 smb_ReceiveNTRename() does not support the File Copy and
666 Move Cluster Information operations described in its interface.
667 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
669 * When opening files via symlinks, we should follow the symlinks
670 until we reach the actual file stat cache entry. The stat cache
671 entry of the file should then be stored in the FID instead of
672 stat scache entry of the symlink.
674 * return bad operation errors for all unimplemented functions
675 even if we do not know the functions exist.
677 * Log bad packets and unknown operation packets to the trace log
679 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
682 * Update list of known CIFS operations to include all those listed
683 in CIFS-TR-1p00_FINAL.pdf.
685 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
686 to support the REG_EXPAND_SZ type.
689 * A new Windows authorization group "AFS Client Admins" is now
690 created and populated with the members of the "Administrators"
691 group. The group is used to determine which accounts on the
692 machine may be used to modify the AFS Client Configuration via
693 the UI and command line tools. afs_config.exe, fs.exe,
695 * Modify the WinLogon Logoff Event Handler to query NT4 domain
696 controllers for the remote profile path if Active Directory
697 services are not available.
699 * Fix aklog.exe to not add the AFS ID to the username
701 * PTS registration of new users to foreign cells has been added to
704 * The cm_Daemon thread is used to perform checks for
705 down servers, up servers, volumes, callback expirations,
706 lock maintenance and token expiration. Due to a gaff in
707 larger integer division the thread never performed any
708 work. Instead the current time computation would always
709 be less then the trigger times. This had an adverse affect
710 on the client's ability to maintain communication with servers,
711 keep volumes up to date, and flush user tokens and acls
712 when they have expired. This was broken when the 1.3 branch
713 was modified to support VC7 which no longer included
716 * An initialization problem with the Freelance code was
717 detected while fixing the callbackRequest. The cm_rootSCachep
718 object is obtained during afsd_InitDaemons() but the callback
719 information is incomplete. The callback information will not
720 be obtained until cm_MergeStatus is called from within
721 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
722 test for the conditions under which the callback information
725 * Reports have been filed indicating that callbacks were
726 being lost. An examination of the code indicated that the
727 cm_server_t objects were not being properly reference
728 counted by the cm_scache_t and cm_callbackRequest_t objects.
729 In particular, the cm_server_t objects may have been freed
730 from beneath the cm_conn_t objects.
732 All of the reference counting is now done via the functions:
737 this improves the ability to track the referrals.
739 Each cm_BeginCallbackGranting Call now allocates a reference
740 to the cm_server_t. The cm_EndCallbackGrantingCall either
741 frees the reference or transfers it to the cm_scache_t
742 cbServerp field. These are then appropriately tracked
743 through the cm_Analyze call.
745 * Ensure that the dnlc hash table is the same size as the
746 dir name hash table (as per original author's note).
747 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
748 for compatibility with 64-bit systems.
750 * fix smb_ApplyV3DirListPatches to properly apply the hidden
751 attribute to dotfiles when the infoLevel < 0x101 and
752 cm_SyncOp has failed.
754 * Fix the Freelance registry initialization code. There
755 was a possibility that some systems could end up with
756 garbage in the registry during a clean install.
759 * file and directory names beginning with "." will now be given the
760 hidden attribute when the volume access is anonymous. this matches
761 the behavior when the volume access is via an authenticated user.
763 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
764 key. When a change occurs mark the root.afs data as invalid and
765 for it to be reloaded on the next access. This allows administrators
766 to modify the mount point list without restarting the service.
768 The freelance client used to provide a fake modification time for
769 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
770 Added code to extract the last modification time of the Freelance
771 registry key and use that instead. The time now represents the
772 most recent mount point change.
774 * PTS registration of new users to foreign cells has been added to
777 * Additional Cache Control and Credential Manager options have been
778 added to the WiX installer. See deployment guide for details.
780 * The CachePath setting is now optionally a REG_EXPAND_SZ type
782 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
785 * The loopback installation code may have had a problem updating the
786 %ETC%\HOSTS file which could have resulted in a premature failure.
787 Work around code has been added for the case where the file cannot
790 * The default max chunksize was increased from 15 (32K) to 17 (128K)
791 because Windows sends 64K blocks when using overlapped writes.
793 * The default number of server threads was increased from 4 to 25 to
794 better handle overlapped writes.
796 * The "AfscredsShortcutParams" registry value was not being properly
797 loaded by afscreds.exe. Therefore, the default value was always being
798 used instead of the value set by the installer.
800 * Windows XP provides downgrade attack detection to prevent an attacker
801 from being able to force the use of NTLM simply by disrupting
802 communication with the KDC. This attack cannot exist between the
803 Windows CIFS client and the AFS Client Service. Therefore, when a
804 downgrade has been detected the afs pioctl library will force the
805 establishment of a new CIFS connection using NTLM.
807 * A locking error was discovered surrounding all references to volume
808 server lists within the cm_cell.c source file.
810 * The logged into Windows username was incorrect on Terminal Server
813 * A new registry value "NonPersistentCaching" was added to the service
814 parameters key. When set to a non-zero value, the afs cache is stored
815 in the Windows paging file. There are two limitations to choosing
817 1. when persistent caching is implemented it won't work with
818 this flag set since there will be nothing to persist.
819 2. with this flag set the initial paging allocation cannot be
820 changed while the service is running
822 * An initialization bug was discovered in aklog.exe which affected users
823 who have a domain name for their afs servers which could not be mapped
827 * afs_config.exe now validates cell names against DNS in addition
828 to the CellServDB file.
830 * In order to allow the freelance client to connect to a volume with ID
831 equal to 1 on the default cell we changed the fake root.afs volume ID
832 once again. This time we choose 0xFFFFFFFF. In addition, we change
833 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
834 It will now be impossible for a volume ID to match that of another
835 cell unless the client is connected to 0xFFFFFFFD cells. That should
836 be enough room for growth.
838 * Fix "fs mkmount" command to work with UNC paths and when
839 started from non-AFS drives. It is now possible to create a mount
840 point in the freelance fake root.afs volume with the command
842 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
846 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
847 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
849 * The algorithm used to re-attempt access to the servers associated with
850 a volume has been altered to properly address the case in which all
851 servers have been marked down. The previous algorithm did not reset
852 the server's down flags so the servers were never actually retried.
853 This caused a problem with active volumes if the network connectivity
854 was lost as could be the case with a network cable removal, wireless
855 drop, or laptop hibernation. With the fix volume access is restored
856 almost instantenously when network connectivity becomes available.
858 * Support for SMB/CIFS browsing has been added to the AFS Client Service
859 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
860 listing of AFS submounts and freelance mount points. Support for
861 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
862 significantly enhances the behavior of AFS volumes within the Explorer
863 Shell. For instance, "AFS" now shows up as server in the Explorer
864 with each submount or freelance mount point visible as a share.
865 The right click menu in each folder now works with full functionality
866 on a consistent basis.
868 * The network provider can be configured to have different behavior
869 depending on the domain that the user logs into. These settings are
870 only relevant when using integrated login. A domain refers to an
871 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
872 local machine (i.e. local account logins). The domain name that is
873 used for selecting the domain would be the domain that is passed into
874 the NPLogonNotify function of the network provider. (see registry.txt
877 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
878 "Authentication Cell" which may be used to specify a default
879 authentication cell for afscreds.exe which is different from
880 the default cell for the AFS Client Service daemon.
882 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
883 afslogon.dll moved to %WINDIR%\System32\.
884 New registry entries added to register the dll for Winlogon events.
886 The logoff event will now force a call to ktc_ForgetAllTokens()
887 using the context of the user being logged off as long as the
888 user's profile is not loaded from within AFS. If the profile
889 was loaded from AFS we can't release the tokens since the Logoff
890 event is triggered prior to the profile being written back to
891 the its source location. This is now performed in an XP SP2
894 * Windows XP SP2 Internet Connection Firewall interoperability
897 * The %WINDIR%\afsdsbmt.ini contains four sections:
898 Submounts, Drive Mappings, Active Maps and CSC Policies.
899 The Submounts and CSC policies are now stored in the registry under
900 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
901 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
902 The Drive Mappings and Active Maps are stored in the registry under
903 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
904 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
906 There is no automatic migration of this data as it would be impossible
907 to consistently migrate data to user profiles which may not be active
908 when the machine is updated.
910 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
911 fake root.afs volume. For the same reasons as for the cellservdb file,
912 this information should not be in %WINDIR%. This information is now
913 kept under the registry key
914 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
916 The data from the afs_freelance.ini file will be automatically
917 migrated to the registry on first execution of afsd_service.exe
919 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
920 troublesome for several reasons. One, it is confusing for those who
921 expect the file to be named "CellServDB" instead of "afsdcell.ini".
922 Two, this file is not a Windows Profile formatted file. Three,
923 applications should not be reading or writing to %WINDIR%. It causes
924 problems for Windows Terminal Server.
926 The new location of CellServDB will be the OpenAFS Client install
927 directory which is by default C:\Program Files\OpenAFS\Client and can
928 be determined by querying the registry for
929 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
931 The existing afsdcell.ini will be migrated by the NSIS installer.
932 The Wix installer must still be updated to do the same.
934 * Change NSIS installer to use DNS by default; to remove Integrated Logon
935 High Security mode; and to add Terminal Services compatibility registry
936 entries to allow the OpenAFS tools to find the afsdcell.ini and other
937 configuration files in %WINDIR%.
939 * Add support for authenticated SMB connections. This will remove
940 the need for high security mode in most situations. Both NTLM
941 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
942 only NTLM can be used even though Kerberos is now supported. The
943 reason is that it is not possible to construct a service principal
944 which is unique to each individual machine.
946 SMB Extended Auth does not work on XP SP2 unless one of two registry
947 modifications are made:
949 (1) To disable the check for matching host names on loopback connections
950 set this key. This does not require a reboot:
952 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
953 "DisableLoopbackCheck"=dword:00000001
955 (2) To add the AFS SMB/CIFS service name to an approved list. This
956 does require a reboot:
958 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
959 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
961 afsd_service.exe will automatically add the current Netbios Name
962 to the BackConnectionHostNames list and then temporarily disable
963 the loopback check for one cycle of startup/shutdown of the service.
964 We assume most folks do not start/stop without a reboot so this
965 will be adequate in most cases.
967 * Fix security hole in afslogon.dll which allowed passwords to be
968 sent in clear text to the KDC in a misformed principal name.
970 * Fix cm_GetCell() to properly handle expired dns entries
973 * If Freelance mode is active and the afs_freelance.ini
974 file does not exist, do not create an empty file.
975 Instead create a file containing ro and rw mountpoints
976 to the default cell using the standard conventions.
978 * Modify the Freelance support to handle the ability
979 to create rw mount points in the fake root.afs volume.
981 * Changed the RPC mechanism used for token setting from
982 named pipes to local. Use of named pipes can be restored
983 by setting the environment variable AFS_RPC_PROTSEQ to
986 Named pipes were required when a Windows 9x system was
987 using a NT system in gateway mode which is incompatible
988 with our use of local loopback adapters.
990 * In afscreds.exe, if a username of the form user@REALM is
991 specified and no password is specified, do not perform a
992 kinit operation. Only perform the aklog functionality.
994 * Add a new registry value which allows the number of processors
995 on which afsd_service.exe executes to be restricted. Valid
996 values are 1..numOfProcessors
998 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
1002 * A second MSI based installer option is now available.
1004 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
1005 request tickets for user/instance@REALM instead of just user@REALM
1007 * Modify the Power Management Notify routine to wait for the Hard Dead
1008 timeout period instead of a fixed 19 seconds. With the longer timeout
1009 periods Hibernation and Standby could never succeed when network
1010 connectivity is not available.
1012 * The following fs.exe commands are now restricted to Administrator:
1013 - checkservers with a non-zero timer value
1016 - sysname with a new sysname list
1025 setting the default sysname for a machine should be done via the
1026 registry and not via "fs sysname".
1028 * NSIS installer adds options to install Debugging Symbols
1029 and the Microsoft Loopback Adapter; the user is now also
1030 given the ability to select the afscreds.exe startup options.
1032 * Build system modified to generate symbols for FREE (aka RELEASE)
1033 builds as well as CHECKED (aka DEBUG) builds
1035 * Sites which have a volume ID of 0x20000001 assigned to their
1036 root.cell volumes have been experiencing problems with accessing
1037 the root.cell volume of their cell when Freelance mode has been
1038 active. This was because 0x20000001 was assigned to the fake
1039 root.afs volume created by freelance. The fake volume id is
1040 now set to 0x00000001 to prevent conflicts.
1042 * The timeout logic in the AFS Client Service has been wrong
1043 for sometime. It is based on two different assumptions.
1044 First, the SMB client timeout is a fix value as was the case
1045 with OS/2 Lan Manager. This assumption is incorrect. The
1046 SMB timeout in Windows is a dynamic value computed based upon
1047 a fixed minimum timeout to which is added time based upon the
1048 size of the request and the performance characteristics of
1049 the connection. Second, it is the responsibility of the
1050 SMB Server to enforce the timeout requirements of the client.
1051 This is untrue. The SMB Server cannot be expected to know
1052 the requirements of the client. More importantly, if the
1053 SMB server uses the SMB client timeout as a value to restrict
1054 its behavior as an RX client, the performance characteristics
1055 of the local SMB session would be used to prematurely terminate
1056 WAN connections with significantly different performance
1059 The timeout logic has therefore been modified in the following
1061 . the Lan Manager Workstation (SMB) Session Timeout is used only
1062 as a basis for configuring the Connection Dead Timeout
1063 and Hard Dead Timeout values. The Connection Dead Timeout
1064 must be at least 15 seconds longer than the SMB Timeout
1065 and the Hard Dead Timeout must be at least double the
1066 Connection Dead Timeout.
1067 . New registry entries have been added to allow the Connection
1068 Dead Timeout and Hard Dead Timeout values independent of the
1069 Lan Manager Workstation Session Timeout
1070 . The test to enforce the SMB Client Timeout has been removed.
1072 One of the side-effects of removing the enforcement of the SMB
1073 Client Timeout is that regardless of whether or not the SMB client
1074 is available to receive the response (and how would the SMB server
1075 know) the RX protocol response can be used to update the AFS
1076 Client Service state for ready access by future SMB client
1079 This should be the end of the "Server paused or restarting messages"
1081 * Add support for arbitrary UNC paths to the pioctl() support.
1082 This enables the fs commands as well as the AFS Shell Extension
1083 to work correctly when UNC paths are being used.
1085 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1086 DNS if the cell configuration cannot be determined via CellServDB
1088 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1089 are ever set more than once at a time
1091 * Fix the management of lists of cm_cell_t structures when using
1092 DNS to lookup cell information. The previous code would fail to
1093 reuse the same cellID for a cell if DNS was used more than once
1094 for a given cell name. When the ttl expired, a single cm_cell_t
1095 could be inserted into the cm_allCellsp list more than once
1096 producing a loop. In addition, the vlServerp list belonging to
1097 the cell was not freed resulting in improper refCounting of the
1100 * Add DNS support to cm_IoctlNewCell() which previous only examined
1103 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1104 to properly garbage collect cm_server_t objects
1106 * Add numVCs variable to smb.c to track the number of smb_vc_t
1107 objects created and use it to initialize the vcID field which
1108 previously was set to 0 in all objects resulting in FindByID
1111 * Fixed DNS lookups to work consistently throughout the OpenAFS
1112 product instead of just from within the afsd_service.exe
1114 * Added a runtime check to ensure that AFS Client Service SMB
1115 Server is accepting connections before attempting to mount
1118 * Read IP addresses for volume servers out of the CellServDB
1119 file if gethostbyname() on the hostname fails.
1121 * Fix getcellconfig() to populate both the Hostnames as well
1122 as IP addresses when loading cell data via DNS
1124 * Increase the Connection Dead Time to 50 from 20 seconds
1125 Increase the Hard Dead Time to 120 from 40 seconds
1126 (matches the Unix values)
1128 * Fixed an assertion validating the number of allocated NCBs
1130 * Fixed the build environment to consistently build for
1131 Windows 2000 and above. (APPVER = 5.0)
1133 * Fixed rx_debug to properly validate the receipt in incoming
1134 data with select() and recvfrom(). Do not copy data out of
1135 the socket buffer unless success is indicated.
1138 * afsd_service.exe will now display a message box to the
1139 desktop when it terminates due to an IP Address Change.
1141 * installer no longer deletes AFS Server configuration data
1144 * installer generates a warning dialog if the RPC service
1145 is not properly configured
1147 * installer compressed with lzma instead of bzip2
1149 * afsd_service.exe shutdown crash solved once and for all
1151 * reference counting of smb_vc_t data structures improved
1153 * name space collision of smb_fid_t event objects corrected
1155 * the output of "fs memdump" is now written to
1156 %WINDIR%\TEMP\afsd_alloc.log
1158 * the file TaAfsApp_1033.dll is now properly installed allowing
1159 the User Manager to start
1161 * a new algorithm is used for computing filename pattern matches
1163 * afscreds.exe now accepts user names containing instance
1166 * Fix the Directory Name Lookup Cache to be case-sensitive.
1167 This is crucial in environments in which a Windows client
1168 is accessing a directory with more than one filename that
1169 differs only by case. If the directory contains "FOO"
1170 and "Foo". You want "DEL Foo" to delete the correct one.
1171 We still have a problem in that "DEL foo" will delete a
1172 random filename. This will be addressed in a future release.
1174 * Fix afscreds.exe -M option (renewMaps) to work when High
1175 Security mode is off. Also, remember to disable the ActiveMap
1176 flag in afsdsbmt.ini when a drive mapping is removed.
1178 * Updates to NSIS installer script. AFS Server configuration
1179 data will not be destroyed on un-install or re-install.
1180 Use a better compression algorithm.
1182 * afslogon.dll now uses KFW to obtain tokens when available
1184 * afslogon.dll when given an all uppercase username will
1185 attempt to authenticate with both the uppercase name
1186 and an all lowercase variation
1188 * DST modification removed. The fix appears to make things
1189 worse after a reboot of the machine.
1191 * fs.exe: added "cscpolicy" which is used to
1192 change client side caching policy for AFS shares
1194 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1195 [-documents] [-disable] [-help]
1197 * Several uninitialized variables have been initialized
1199 * It is now possible to obtain tokens using cross realm
1200 Kerberos within afscreds.exe:
1202 user: jaltman@ATHENA.MIT.EDU
1204 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1205 will will in turn be used to obtain afs@DEMENTIA.ORG.
1206 The resulting token will be stored with the display name
1207 jaltman@ATHENA.MIT.EDU@dementia.org
1209 * aklog.exe has been added to the client
1211 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1212 [[-p | -path] pathname]
1216 -d gives debugging information.
1217 krb_realm is the kerberos realm of a cell.
1218 pathname is the name of a directory to which you wish to authenticate.
1219 -noprdb means don't try to determine AFS ID.
1220 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1221 (default is Kerberos V)
1222 No commandline arguments means authenticate to the local cell.
1225 * All of the resource files have been restructured to adhere to
1226 a set of rules IBM implemented for loading string resources.
1227 These rules had either been forgotten or were not discovered
1228 by folks working on the OpenAFS sources. The end result was
1229 memory corruption. This is primary item which was preventing
1230 the AFS Server from working.
1232 * Increased the size of the maximum ticket size stored in a token
1233 from 344 bytes to 12,000. Increased the buffers used to convey
1234 messages between the pioctl() caller and the SMB Server from
1235 1000 bytes to 12,512. The code appeared to have been writing
1236 above the top of the stack by quite a few number of bytes.
1237 (The increased ticket size is necessary for the next item.)
1239 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1240 Instead the raw Kerberos 5 ticket is used in its entirety. This
1241 is extremely important as it allows us to use pure Kerberos 5 KDCs
1242 as the source of the AFS authentication. The use of up to 12,000 byte
1243 tickets will allow tickets produced by all versions of Microsoft
1244 Active Directory to be used.
1245 - create a user account.
1246 - designate it DES only
1248 - specify its UPN to be "afs@realm"
1249 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1251 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1252 is special when using long file names. (you must use "*.*" and not "*")
1253 Instead only enforce it when performing 8dot3 searches.
1255 * Fixed the DST problem with creation times being set one hour ahead
1257 * Fixed the problem when using \\afs\cell-alias. For example,
1258 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1259 for the alias name; instead simply expand the name. One of the
1260 symptoms of this problem was a loss of acquired tokens.
1262 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1263 of strings. (Only English strings provided.)
1265 * Fixed the installer to properly replace in use files.
1267 * Fixed the build system to cleanup generated component version files
1269 * The release build compiled with MSVC 6.0 compiler to avoid the
1270 afsd_service.exe shutdown crash. This does not solve the problem
1271 but simply avoids it for the time being.
1275 * fix afslogon.dll to not corrupt memory when High Security mode
1278 * fix afsd_service.exe to not attempt to restore the stack when
1279 an exception occurs. (not safe in multi-threaded programs)
1281 * fix uninstaller to properly remove the CRT and MFC DLLs
1283 * remove a Message Box from afscreds.exe when getcellconfig()
1284 fails on a kerberos realm which is not a cell
1286 The following is a list of changes to the OpenAFS for Window client
1289 * "fs setserverprefs" will leave afsd service deadlocked
1291 * "vos listaddrs" will core dump
1293 * installer sets the appropriate keys to support Integrated Logon
1295 * installer disables the "Find Lana by Name" functionality as it
1296 was causing headaches for many users
1298 * fix the intermittent crash of the power management thread when
1299 shutting down the AFS Client Service
1301 * optimizes the obtain drive mount list functionality which is
1302 executed every time the mount tab in afscreds.exe and afs_config.exe
1303 are refreshed. (this happens a lot)
1305 * fix the service shutdown logic. add the STOP_PENDING state
1306 and do not accept additional service events after we declare
1309 The following is a list of changes to the OpenAFS for Window client
1312 * flexelint was run against the source tree and hundreds (perhaps
1313 thousands) of corrections were applied to ensure prototypes
1314 were in use; types were used consistently; variables were
1315 initialized; unused variables were removed; etc.
1317 * A wide variety of instrumentation was added including the
1318 ability to produce a stack trace from within afsd_service.exe
1321 * Dynamic configuration of the RDRtimeout value based upon the
1322 LanMan Workstation Session Timeout
1324 * The mount root no longer needs to be called "/afs". This
1325 is now set by a registry value "MountRoot" within the key
1326 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1328 * The cell list is now only read out of afsdcell.ini when the
1329 file changes instead of each time a cell is resolved.
1331 * Thread synchronization was added to cm_server.c and ktc_nt.c
1333 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1334 calloc()/free(). The Global functions were needed on Windows 3.x
1335 but have caused a variety of problems on the Win32 platforms.
1336 Avoiding them is highly recommended by several Microsoft
1337 Knowledgebase articles
1339 * Support for Symbolic Links added to the AFS Shell Extension
1341 * Added a registry value "OverlayEnabled" to determine if
1342 Shell Extension Overlays should be enabled.
1343 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1345 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1346 separate trees for checked and free builds. Build system supports
1347 a custom directory src\WINNT\extra which can be used as a grafting
1348 location of organization specific additions to the build tree.
1350 * New installer built using NSIS 2.0.
1352 * Named all kernel objects in order to allow them to be monitored
1353 with tools such as SysInternals' ProcExp.exe.
1355 * Introduced new EventLog framework for AFSD
1357 * Introduced Power Management interface to AFSD for Standby and
1358 Hibernate modes to allow cache to be flushed prior to network
1361 * Utilize Win32 DNSQuery API instead of internal routines. This
1362 allows DNS SRV queries to be sent to all current domain name
1363 servers. Not just one specified in an INI file. DNS is now
1366 * "NetbiosName" registry value may be used to specify a fixed
1367 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1368 when the loopback adapter is in use. If you need to use the
1369 old notation with a loopback adapter installed specify a registry
1372 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1374 * Refactor all modules which depend on LAN Adapter and NetbiosName
1375 determination in a new library: lanahelper.lib. This allows for
1376 consistent behavior throughout the product.
1378 * Move the afsd.log and afsd_init.log files to the directory specified
1379 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1380 for services. Added the Date to the log entries.
1382 * New registry value "RxMaxMTU" used to limit the size of the RX
1383 packets sent by the AFS Client Service to the Server. In order
1384 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1385 size must be restricted to 1264 or smaller. The latest NSIS
1386 installer sets a value of 1260 by default.
1388 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1389 packets. This is not needed in order to work across the Cisco
1390 VPN but might be needed for other network environments. This
1391 value is not set by the NSIS installer.
1393 * New registry value "HideDotFiles" is used to apply the Hidden
1394 attribute to files whose names begin with a '.'. This value
1395 is set by the NSIS installer.
1397 * New registry value "MaxMpxRequests" allows the maximum number
1398 of multiplexed sessions to be configured at run time. This
1399 value is not set by the NSIS installer. The default value is
1402 * New registry value "MaxVCPerServer" allows the maxmimum number
1403 of VCs per server to be configured at run time. This value is
1404 not set by the NSIS installer. The default value is 100.
1406 * New registry value "AllSubmount" allows the "all" submount to
1407 be disabled by setting its value to 0x00.
1409 * Allow cells names to be valid mount points
1410 \\<netbiosName>\<cellname>
1412 * Store the active state of drive mappings in order for afscreds.exe
1413 to restore them upon startup
1415 * Add exception handling to generate a Stack Trace to the afsd_init.log
1416 file if one happens to occur.
1418 * Add lots of logging to help detect the cause of invalid SMB packets
1420 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1421 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1422 renewal of expiring tokens as long as afscreds.exe is running.
1424 * New afscreds.exe command line options:
1426 -M = renew drive maps
1427 -N = ip address change detection
1430 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1431 determines whether or not MIT Kerberos for Windows should be used
1432 to obtain tokens via Kerberos 5 tickets.
1434 * New registry value "AfscredsShortcutParams" in
1435 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1436 determines the command line parameters to be specified when "fixing"
1437 the AFS Shortcut in the user's startup folder.
1439 * The "ShowTrayIcon" registry value has been moved from
1440 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1441 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1443 * The <cell name> registry values used to store the token expiration
1444 reminders have been moved from
1445 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1446 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1448 * Obtain the Logon User Name from the Explorer key when available
1450 * new text document doc\txt\winnotes\registry.txt lists all registry
1451 values used by OpenAFS (excluding the AFS Server)
1453 * BUG: rx_securityClass objects were not properly reference
1454 counted and were never freed.
1456 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1457 would be generated. The existence of a server does not imply
1458 that it is not down. If all of the servers for a cell are down
1459 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1462 * BUG: the directory name lookup cache failed to free the entries
1463 in the cache when the name cache entries cycled. The entries
1464 in the cache would become dereferenced without being freed.
1466 * BUG: fs setserverprefs could be executed without Administrator
1469 * BUG: the number of allocated NCB objects (100) exceeded the number
1470 which could actually be waited upon by the kernel (64). Any objects
1471 which were utilized above the limit could never have event completions
1474 * BUG: smb_username_t objects were not being reference counted and
1475 were not properly freed.
1477 * BUG: smb_tid_t objects could under unusual circumstances be freed
1478 before they were no longer referenced.
1480 * BUG: smb_fid_t object pointer were frequently used even when
1481 their value could be NULL. They were not properly released and
1482 therefore they were never freed.
1484 * BUG: smb_packet_t data structures were not completely initialized
1487 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1488 Denied" because that causes the Explorer Shell to try again until
1489 access is obtained. Instead return "Remote Resources" which allows
1490 the shell to move on and treat the error as transient.
1492 * BUG: when initializing the NCBreturns structure, separate Event objects
1493 were created for each NCB although a single Event object was supposed
1494 to be shared by all.
1496 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1499 * BUG: smb_tran2Packet_t objects were not being properly referenced
1502 * BUG: directory path creation did not handle the case of multiple
1503 directories requiring creation in one attempt
1505 * BUG: SMB requests which required an Extended Response were ignored.
1506 This prevented some files from being written to AFS volumes.
1508 * BUG: character strings were being freed even after they were
1509 inserted into in use data structures
1511 * BUG: inconsistent usernames were used when High Security mode was
1512 enabled. (there is still much to do in this area)
1514 * BUG: pioctl() calls which require out of band RPC operations were
1515 susceptible to race conditions when performed by multiple processes
1517 * BUG: memory allocation and deallocation crossed instances of the
1518 C Runtime Library producing memory leakage and corruption in
1519 afscreds and the client configurator.
