2 * Fix a regression introduced into the pioctl() client code which
3 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
4 MIT KFW is not installed.
6 * Remove AFS Gateway option from OpenAFS Control Panel
9 * Fix a race condition in cm_EndCallbackGrantingCall() that
10 could leave 'nrevp' pointing to freed memory. In the process,
11 optimize the processing to ensure that the applications monitoring
12 the status of the stat cache entry are only notified at most
15 * Conditionalize access to the Explorer Shell AFS->Mount Point
16 ->Remove menu item. Disable the item if the selected item(s)
19 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
20 Local Storage. This eliminates thread contention on the
21 global RX free packet queue. This should improve performance
24 * Fix the IP address filtering code to properly load/unload
25 the IPHelper DLL so that Windows XP/2003 and beyond systems
26 do not have to manually probe the registry.
28 * CleanupACLEnt() was not being called consistently with
29 the cm_scache_t object referred to by the back pointer
30 mutex locked. This could in very rare conditions lead to
31 an invalid memory access.
33 * Added a script command to the msi installer "afs_replace"
34 which can be used to replace one version of OpenAFS with
35 another without requiring an uninstall and reinstall if
36 the installed msi is no longer in its original location.
38 * Apparently the problem with multi-domain forests with cross-
39 realm trusts to non-Windows realms was not entirely solved.
40 The authentication to the AFS SMB service failed because
41 the wrong name was being used. Using ASU as an example,
42 the authentication was being performed with the name
43 "QAAD\user" (an account in the forest root) and not
44 "user@ASU.EDU (the MIT Kerberos principal used to login with)
46 The solution was to add an additional dependency on KFW
47 in order or to be able to easily obtain the client principal
48 name stored in the MSLSA ccache TGT. This information is
49 used in two locations:
51 - the pioctl() function
53 - a new WinLogon Event Handler for the "logon" event.
55 The pioctl function will now be able to use the correct
56 name when calling WNetAddConnection2() and the "logon"
57 event handler will now be able to call WNetAddConnection2().
58 The hope is that the "logon" event handler will be called
59 before the profile is loaded but I have not guarrantee
63 * Fixed a locking error in cm_TryBulkStat() which had the
64 potential of deadlocking the system for the length of time
65 it takes to perform a bulk status fetch operation.
67 * Replaced time conversion code (UnixTime <-> FILETIME) to
68 be completely arithmetic instead of relying on a bizarre
69 algorithm involving a variety of C RTL time functions.
70 This has the side effect that UnixTime and FILETIME which
71 are both stored in UTC are interpretted as UTC throughout
72 the year. Windows will apply the same localization to AFS
73 as it does to NTFS. Applications which rely on the ability
74 to sync files between the two file systems will no longer
75 see the timestamps of files in AFS change an hour relative
76 to the files stored in NTFS or Windows based backup devices.
78 * Fixed a invalid memory access under a bizarre circumstance.
79 Windows will allow a physical mass media device to be
80 installed via Plug N Play to the system and will assign it
81 the lowest available drive letter. This is true even if the
82 drive letter is currently assigned in the user session to
83 a network device via NET USE (or its equivalent.) When this
84 happens, queries sent to the CIFS server will contain invalid
85 data. This invalid data was not being caught by the AFS
86 Client Service and was resulting in a crash when Freelance
89 * Fixed a reference count error when registering callbacks
90 on a stat cache object if the callback was already registered
92 * Add a case to cm_Analyze() in order to handle the case where
93 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
94 the server list for the volume is empty. In this case, force
95 an update of the volume info and retry.
97 * Insert a missing cm_EndCallbackGrantingCall() which could
98 result in threads waiting for a callback to complete to never
101 * In the persistent cache, there is a maximum number of volume
102 entries. Allow volume entries to be reused if the maximum
103 number have been allocated and their reference count is zero.
105 * If we already have a dead virtual connection object, don't
106 ignore the fact that additional dead vc objects must be taken
109 * Removed a deadlock condition introduced in the summer of 2004.
110 Do not hold mx locks around calls to RX functions including
111 rx_NewCall(). That is what reference counts on the rx_connection
114 * Fixed an initialization error in afslogon.dll which could
115 result in random behavior including a failure to terminate
116 the NPLogon function. (1.3.80b)
118 * Fixed an error preventing the use of SMB authentication
119 on Windows 2000. (1.3.80a)
122 * Updated CellServDB to Public CellServDB 16 Mar 2005
124 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
125 misinterpretted as "csail.mit.edu" when the resolver
126 is configured to append ".mit.edu" to failed DNS queries.
128 * Fixed another case in which the client would replace connections
129 to the host when it was not necessary. In this case the
130 situation would occur if cryptall was on and the connections
131 were unauthenticated due to lack of an appropriate token.
133 * OpenAFS for Windows has failed to work at sites which are
134 utilizing a cross-realm trust between an MIT/Heimdal realm
135 and a multi-domain Windows forest when the workstation being
136 accessed is not located in the root domain. This is caused
137 by a bug in the workstation which was triggered after the
138 introduction of Windows 2003 Server. When the bug is triggered,
139 the workstation attempts to authenticate users to afsd_service.exe
140 by contacting the Domain Controller instead of using the
141 LSA loopback authentication mechanism.
143 One of the reasons this bug occurs is because the workstation
144 does not have a reliable way of knowing that the service whose
145 netbios name is "AFS" is located on the workstation. This will
146 be fixed starting in Longhorn Beta 1 by Microsoft. The
147 "BackConnectionHostNames" registry value will be used to
148 indicate that the authentications to that service name should
149 be performed using the loopback authentication mechanism.
151 In the meantime, when Logon Caching is enabled, we can force
152 afsd_service.exe to authenticate using the logon cache before
153 contacting the Domain Controller. This will work with both
154 password and smart card based logons.
156 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
157 flag should not be cleared if a volume's server reference is
158 marked as "offline". In the case where all of the volume's
159 servers are either "down" or the volumes are "offline", we want
160 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
161 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
162 should never occur in practice.
164 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
165 5 seconds, clear the server down and volume busy flags, and
166 then force an update from the VLDB. This allows the client to
167 update the location of a volume if the reason for it being
168 marked offline is because it is being moved. Calls to
169 cm_ConnByMServers() will be retried either until success or
170 the RDRtimeout period is reached.
172 * Correct the Power Management code behavior in response to
173 Standby, Suspend, and Shutdown events. Instead of flushing the
174 buffers associated with the mounted SMB submounts, simply write
175 all buffers which are marked dirty.
177 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
178 provides a list of cells other than the default cell for which
179 tokens should be obtained using the default Kerberos principal.
180 This functionality is logon domain specific and is only available
181 when using KFW for authentication.
183 * Fixed FindNext Invalid Handle error caused by over agressive
184 attempts at garbage collecting dirSearch entries when the
185 dirSearch ID wraps from the maximum value to 1.
187 * Add support for registry defined server preferences for VLDB and
188 File servers. See registry.txt for details.
190 * Increased default cache size to 96MB and default number of cache
193 * Fixed refCount leaks related to directory lookups and pioctl calls.
195 * Callbacks revoked during a race condition with an attempt to
196 obtain the same callback no longer result in an inaccessible
199 * New command line tool:
201 afsdacl : Set or reset the DACL to allow starting or stopping
202 the afsd service by any ordinary user.
204 Usage : afsdacl [-set | -reset] [-show]
206 -reset : Reset the DACL
207 -show : Show current DACL (SDSF)
209 * IP addresses are no longer queried once at startup. Instead IP
210 addresses are obtained as needed. Loopback adapter addresses are
211 no longer published to the server.
213 * Pay attention to the MIT KFW registry configuration for automatic
214 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
216 * Fix (once again) case-sensitive comparisons which was apparently
219 * Activate support for vos listvol -format
221 * Population of the "AFS Client Admins" group failed on non-English
222 versions of Windows because the name of the "Administrators" group
223 is localized. Now we lookup the name of the group by using the
224 Administrators Group Alias Relative ID.
226 * Multiple cell token acquisition within afscreds.exe was broken in the
227 case of Kerberos 5 cross realm authentication. Instead of contacting
228 the KDC associated with the cell's realm, afscreds would obtain a
229 token from the KDC of the user's realm. This would result in
230 "invalid kvno errors" while authenticating to the AFS servers.
231 Unauthenticated access would work. The symptoms would vary based upon
232 whether or not the VLDB servers had been contacted using unauthenticated
233 connections prior to the user obtaining tokens.
235 * The list of ACL entries was becoming corrupted. It appears as if
236 an ACL when it expires was not being appropriately cleaned up. In
237 fact, it was left in the list of ACLs associated with the scache
240 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
241 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
242 and "amd64_win64" for amd 64-bit processors.
244 * When executing executables, Windows provides a mechanisms by which
245 the normal search for DLLs can be bypassed. If a file foo.exe is
246 being executed and there exists a file or directory "foo.exe.local"
247 (the contents are ignored if a file), then Windows will search for
248 DLLs first in the "foo.exe.local" directory and second in the
249 directory in which the "foo.exe" file is located.
251 Previous releases of OAFW would improperly return
252 STATUS_NOT_A_DIRECTORY instead of the expected
253 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
254 to terminate the search for the DLL causing the execution of the
257 * Rework the reference counting of smb_vc_t objects. The references
258 stored in the waiting locks were not counted. This could result in
259 an assertion if the reference count drops to zero.
261 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
262 when running in freelance mode.
264 * Added support for persistent caching of file contents, stat entries,
265 volume data, cell data, and name lookup data. When the registry
266 value, "NonPersistentCaching", is not defined or set to 0 the file
267 specified by "CachePath" becomes a persistent cache file. The
268 size of the cache file is computed at run time. It has a maximum
269 size of approximately 1.2GB. The contents of the file will be
270 validated according to the rules specified by the "ValidateCache"
273 * Added support for UUIDs. UUIDs are kept for as long as the
274 cache file is intact.
276 * Added cmdebug.exe and support cache manager debugging callback
277 interfaces in afsd_service.exe.
279 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
280 [-addrs] [-cache] [-help]
281 Where: -long print all info
282 -addrs print only host interfaces
283 -cache print only cache configuration
285 * Symlinks to \\AFS\[all\]... will now be treated the same as
286 symlinks to /afs/.... However, please use /afs/... as otherwise
287 the symlinks won't work on Unix.
289 * Correct a problem with local CellID allocation for cells whose
290 server list is obtained via DNS instead of a CellServDB file. If
291 the DNS information expires the CellID assigned to the entry will
292 be changed. This causes all of the cm_scache_t objects which refer
293 to the old cellID number to become useless. Attempts to access
294 files or directories with cm_scache_t objects using the old cellID
295 will fail since the server list cannot be obtained.
297 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
298 be triggered if the volume referenced by the cm_scache_t object is
301 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
302 in addition to SERVICE_ACCEPT_STOP.
304 * Move RPC shutdown until after the SMB and RX shutdown procedures
305 complete. Block until RPC shutdown is complete.
307 * Modify afslogon.dll (integrated logon) to wait for service if its
308 state is START_PENDING. If the timeout period occurs, reset to
309 the retry interval and not the sleep interval.
311 * When renewing the server list for a cell obtained via DNS AFSDB
312 records, the cm_cell_t entry must be removed from the list of all
313 cells. Otherwise, the list of cells will be corrupted.
315 * In the dcache and scache modules, use the cm_scache_t dataVersion
316 instead of the cm_fakeDirVersion.
318 * Synchronize fs.c with the unix version.
320 * The variable used to determine whether a file or virtual memory
321 mapped cache is used was not properly initialized to a default
322 value. If the registry setting "NonPersistentCaching" was not
323 set, the choice would be random. Properly initialized to be
326 * The memory mapped view was never unmapped before closing the file
327 at service shutdown. This is now properly cleaned up.
329 * Default location of Cache file is now %TEMP%\AFSCache
333 * A bug affecting new installations of 1.3.75/76 would result in
334 the creating of incorrect mountpoints in the freelance root.afs
335 volume for the default cell.
337 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
338 of "root.cell", you have been affected by the bug. To correct the
339 problem, execute the following commands:
341 fs rmmount \\afs\all\<cellname>
342 fs rmmount \\afs\all\.<cellname>
344 fs mkmount \\afs\all\<cellname> root.cell <cellname>
345 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
349 * A bug has been fixed in the auto-generation of Freelance root.afs
350 symlinks which produced random entries in the \\AFS\all directory.
352 * Support has been added for multi-homed servers
355 * Added a new registry value, "StoreAnsiFilenames", which can be used
356 to force the use of ANSI character sets instead of OEM Code Pages.
357 This feature is useful when users require the ability to create
358 filenames with 8-bit characters and need to access the files from
359 both Latin-1 based Unix systems as well as from Windows.
361 Activation of this feature will prevent access to files stored with
362 8-bit OEM characters.
364 * Shutdown all SMB threads in a synchronized manner when stopping the
367 * There is currently a maximum cache size of 1.3GB. The limit is imposed
368 by the largest contiguous block of unused memory within the 2GB process
369 space which can be assigned to the memory mapped file. Unfortunately,
370 when the executable digital signature verification code is activated
371 Windows sees fit to further segment the process memory which in turn
372 reduces the size of the maximum cache file to less then 800MB. If
373 larger cache sizes are desired, a new registry value should be set:
375 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
377 Setting this value will disable the runtime verification of digital
378 signatures on afsd_service.exe and the afs dlls which it loads. It
379 will not disable the the version number check on those same files.
380 The signature verification is not a security messure and is only meant
381 to enhance the ability to afsd_service.exe to detect potential
382 destablizing mixtures of DLLs from incompatible distributions.
384 Added code to auto-disable the signature verification check if
385 the desired cache size is greater then 700MB.
387 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
388 used to verify the validity of the afsd_service.exe binary
389 as well as each of the AFS DLLs loaded by the service. Not only
390 must the digital signature be valid but the signatures of the
391 DLL must be signed by the same entity as the service.
393 * Implement new functions: cm_freelanceMountPointExists and
394 cm_freelanceSymlinkExists. Use them along with other validity
395 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
396 ensure that name collisions do not occur and that empty strings
397 are not valid file names.
399 A symlink may not have a name which would resolve to a valid
400 cell name. Doing so would prevent access to the cell.
402 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
403 re-initialization code. The reference counts of the fake root.afs
404 volume scache object(s) would become invalid when the mount point
405 or symlink lists were altered.
407 * Add registry entries to provide mappings from the afsdsbmt.ini
408 to the new locations for applications which count on the use
409 of the old Profile file APIs. These apps are likely to fail
410 if the user does not have administrator privileges and the
411 registry is locked down.
413 * The afs_config.exe submounts dialog had two errors.
414 First, attempts to remove entries failed because the registry
415 key was being opened without KEY_WRITE privileges.
416 Second, when editing a submount entry, changing the name
417 would add a new key and leave the original one in place.
418 Now the original submount will be removed if its name is
421 * In recent months there have been several incidents in which
422 users have experienced problems starting or accessing
423 afsd_service.exe and after significant effort has been spent
424 it has turned out that they have two versions of AFS on the
425 machine or an inconsistent set of DLLs.
427 Code has now been added to afsd_service.exe which will walk
428 the list of modules loaded by afsd_service.exe and validate
429 that the version of the AFS DLLs matches the version of the
430 afsd_service.exe executable. If they do not match the service
433 * When Freelance mode is enabled and there is no registry
434 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
435 will attempt to import the afs_freelance.ini file contents.
436 If the file does not exist, it was creating a dummy file
437 with a r/o and r/w entry for the default cell and then
438 importing those values.
440 This process has been changed. The temporary file is no
441 longer created. Also, both the OpenAFS Client install
442 directory as well as %WINDIR% are checked for previous
443 afs_freelance.ini files.
445 * Added support for VL_GetEntryByNameN(). Still need to add
446 support for VL_GetEntryByNameU() for multi-homed support.
448 * Fix a deadlock situation in afscreds.exe when canceling an
449 auto-generated Obtain Tokens dialog
452 * Fix the locking of objects during Directory Searches in the
453 SMB/CIFS server. The failure to properly lock the reference
454 counts was resulting in the premature freeing of smb_dirSearch_t
455 objects while they were still in use by the SMB/CIFS client.
456 This does not solve the "Invalid Handle" problem.
458 * Fix Find Cell By Name pioctl call to return a valid cell
459 name for the Freelance fake root.afs volume.
460 "Freelance.Local.Root".
462 * Fix the Explorer Shell Extension Symlinks->Add operation.
463 The dialog template was missing and the link destination
464 string was too short.
466 * Add support for symlinks to Freelance root.afs volume
467 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
468 <number> = "<linkname>:<relative-path>."
469 Use symlink.exe to create, list, or remove
471 * Remove the fallback to the use of KFW's KRB4 library when obtaining
472 tokens. We never obtain KRB4 tickets.
474 * Fix AFS Client Configuration Control Panel to support new SysName
477 * Fix a bug in afsd_service.exe which could result in the SysName
478 not being read from the registry.
481 * Add code to block the issuance of AFS tokens by aklog.exe or
482 afscreds.exe when the Kerberos 5 principal name contains a dot.
484 * Modify the IsAdmin() function to always treat the local SYSTEM
485 account as an AFS client administrator. Affects fs.exe and
488 * Modify the internal handling of Quota Exceeded errors
490 * Upgrade all reference count fields in the Windows cache manager
491 and the osi library to use unsigned long instead of signed short.
492 A similar fix has been applied to the afs rpc (rx) library.
494 * fix the Windows cache manager to prevent it from replacing the
495 rx_connection object associated with the cm_conn_t object on each
496 and every operation if "fs crypt" was set. This explains the
497 dramatic performance difference when crypt is used vs clear.
498 The problem: 'cryptall', a boolean flag indicating whether or not
499 "fs crypt" is set, was being compared to the rx_connection
500 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
501 1 != 2 and therefore the rx_connection was always destroyed
502 and replaced on each and every operation.
504 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
505 It is not safe for the cm_conn_t object to not be locked because
506 rx_DestroyConnection might be called from another thread if:
507 - the user's tokens have changed or expired
508 - the crypt mode has changed
510 This fix appears to have also taken care of the problems associated
511 with Overlapped Writes resulting in Delayed Write errors.
513 * fix NSIS installer's AdminGroup.exe to properly create and
514 remove groups when given -create or -remove. The string comparison
517 * fs sysname now accepts a list of sysname values
519 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
520 DWORD which when set to a non-zero value will cause error message
521 text to be output to stderr from the pioctl() routine. Useful in
522 debugging failures of fs.exe, tokens.exe, etc.
524 * added a test to the power management code to only perform a
525 flush operation if there is at least one network adapter which
526 is not a loopback adapter.
528 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
529 "EnableKFW". This value will not be read if the key
530 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
531 value under that key does not.
533 * provide mechanisms to force the use of krb524d for Kerberos 5
534 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
535 there is a new registry value "Use524" and for aklog.exe a new
536 command line parameter "-m".
538 * Fix the pattern matching algorithm to properly match patterns
541 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
542 which is used by both the original function and the new
543 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
544 creation of HardLinks in addition to Renaming. smb_Link()
545 is a new function which creates HardLinks via cm_Link().
546 cm_Link() is a new vnodeops function which creates links
549 smb_ReceiveNTRename() does not support the File Copy and
550 Move Cluster Information operations described in its interface.
551 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
553 * When opening files via symlinks, we should follow the symlinks
554 until we reach the actual file stat cache entry. The stat cache
555 entry of the file should then be stored in the FID instead of
556 stat scache entry of the symlink.
558 * return bad operation errors for all unimplemented functions
559 even if we do not know the functions exist.
561 * Log bad packets and unknown operation packets to the trace log
563 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
566 * Update list of known CIFS operations to include all those listed
567 in CIFS-TR-1p00_FINAL.pdf.
569 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
570 to support the REG_EXPAND_SZ type.
573 * A new Windows authorization group "AFS Client Admins" is now
574 created and populated with the members of the "Administrators"
575 group. The group is used to determine which accounts on the
576 machine may be used to modify the AFS Client Configuration via
577 the UI and command line tools. afs_config.exe, fs.exe,
579 * Modify the WinLogon Logoff Event Handler to query NT4 domain
580 controllers for the remote profile path if Active Directory
581 services are not available.
583 * Fix aklog.exe to not add the AFS ID to the username
585 * PTS registration of new users to foreign cells has been added to
588 * The cm_Daemon thread is used to perform checks for
589 down servers, up servers, volumes, callback expirations,
590 lock maintenance and token expiration. Due to a gaff in
591 larger integer division the thread never performed any
592 work. Instead the current time computation would always
593 be less then the trigger times. This had an adverse affect
594 on the client's ability to maintain communication with servers,
595 keep volumes up to date, and flush user tokens and acls
596 when they have expired. This was broken when the 1.3 branch
597 was modified to support VC7 which no longer included
600 * An initialization problem with the Freelance code was
601 detected while fixing the callbackRequest. The cm_rootSCachep
602 object is obtained during afsd_InitDaemons() but the callback
603 information is incomplete. The callback information will not
604 be obtained until cm_MergeStatus is called from within
605 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
606 test for the conditions under which the callback information
609 * Reports have been filed indicating that callbacks were
610 being lost. An examination of the code indicated that the
611 cm_server_t objects were not being properly reference
612 counted by the cm_scache_t and cm_callbackRequest_t objects.
613 In particular, the cm_server_t objects may have been freed
614 from beneath the cm_conn_t objects.
616 All of the reference counting is now done via the functions:
621 this improves the ability to track the referrals.
623 Each cm_BeginCallbackGranting Call now allocates a reference
624 to the cm_server_t. The cm_EndCallbackGrantingCall either
625 frees the reference or transfers it to the cm_scache_t
626 cbServerp field. These are then appropriately tracked
627 through the cm_Analyze call.
629 * Ensure that the dnlc hash table is the same size as the
630 dir name hash table (as per original author's note).
631 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
632 for compatibility with 64-bit systems.
634 * fix smb_ApplyV3DirListPatches to properly apply the hidden
635 attribute to dotfiles when the infoLevel < 0x101 and
636 cm_SyncOp has failed.
638 * Fix the Freelance registry initialization code. There
639 was a possibility that some systems could end up with
640 garbage in the registry during a clean install.
643 * file and directory names beginning with "." will now be given the
644 hidden attribute when the volume access is anonymous. this matches
645 the behavior when the volume access is via an authenticated user.
647 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
648 key. When a change occurs mark the root.afs data as invalid and
649 for it to be reloaded on the next access. This allows administrators
650 to modify the mount point list without restarting the service.
652 The freelance client used to provide a fake modification time for
653 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
654 Added code to extract the last modification time of the Freelance
655 registry key and use that instead. The time now represents the
656 most recent mount point change.
658 * PTS registration of new users to foreign cells has been added to
661 * Additional Cache Control and Credential Manager options have been
662 added to the WiX installer. See deployment guide for details.
664 * The CachePath setting is now optionally a REG_EXPAND_SZ type
666 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
669 * The loopback installation code may have had a problem updating the
670 %ETC%\HOSTS file which could have resulted in a premature failure.
671 Work around code has been added for the case where the file cannot
674 * The default max chunksize was increased from 15 (32K) to 17 (128K)
675 because Windows sends 64K blocks when using overlapped writes.
677 * The default number of server threads was increased from 4 to 25 to
678 better handle overlapped writes.
680 * The "AfscredsShortcutParams" registry value was not being properly
681 loaded by afscreds.exe. Therefore, the default value was always being
682 used instead of the value set by the installer.
684 * Windows XP provides downgrade attack detection to prevent an attacker
685 from being able to force the use of NTLM simply by disrupting
686 communication with the KDC. This attack cannot exist between the
687 Windows CIFS client and the AFS Client Service. Therefore, when a
688 downgrade has been detected the afs pioctl library will force the
689 establishment of a new CIFS connection using NTLM.
691 * A locking error was discovered surrounding all references to volume
692 server lists within the cm_cell.c source file.
694 * The logged into Windows username was incorrect on Terminal Server
697 * A new registry value "NonPersistentCaching" was added to the service
698 parameters key. When set to a non-zero value, the afs cache is stored
699 in the Windows paging file. There are two limitations to choosing
701 1. when persistent caching is implemented it won't work with
702 this flag set since there will be nothing to persist.
703 2. with this flag set the initial paging allocation cannot be
704 changed while the service is running
706 * An initialization bug was discovered in aklog.exe which affected users
707 who have a domain name for their afs servers which could not be mapped
711 * afs_config.exe now validates cell names against DNS in addition
712 to the CellServDB file.
714 * In order to allow the freelance client to connect to a volume with ID
715 equal to 1 on the default cell we changed the fake root.afs volume ID
716 once again. This time we choose 0xFFFFFFFF. In addition, we change
717 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
718 It will now be impossible for a volume ID to match that of another
719 cell unless the client is connected to 0xFFFFFFFD cells. That should
720 be enough room for growth.
722 * Fix "fs mkmount" command to work with UNC paths and when
723 started from non-AFS drives. It is now possible to create a mount
724 point in the freelance fake root.afs volume with the command
726 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
730 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
731 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
733 * The algorithm used to re-attempt access to the servers associated with
734 a volume has been altered to properly address the case in which all
735 servers have been marked down. The previous algorithm did not reset
736 the server's down flags so the servers were never actually retried.
737 This caused a problem with active volumes if the network connectivity
738 was lost as could be the case with a network cable removal, wireless
739 drop, or laptop hibernation. With the fix volume access is restored
740 almost instantenously when network connectivity becomes available.
742 * Support for SMB/CIFS browsing has been added to the AFS Client Service
743 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
744 listing of AFS submounts and freelance mount points. Support for
745 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
746 significantly enhances the behavior of AFS volumes within the Explorer
747 Shell. For instance, "AFS" now shows up as server in the Explorer
748 with each submount or freelance mount point visible as a share.
749 The right click menu in each folder now works with full functionality
750 on a consistent basis.
752 * The network provider can be configured to have different behavior
753 depending on the domain that the user logs into. These settings are
754 only relevant when using integrated login. A domain refers to an
755 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
756 local machine (i.e. local account logins). The domain name that is
757 used for selecting the domain would be the domain that is passed into
758 the NPLogonNotify function of the network provider. (see registry.txt
761 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
762 "Authentication Cell" which may be used to specify a default
763 authentication cell for afscreds.exe which is different from
764 the default cell for the AFS Client Service daemon.
766 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
767 afslogon.dll moved to %WINDIR%\System32\.
768 New registry entries added to register the dll for Winlogon events.
770 The logoff event will now force a call to ktc_ForgetAllTokens()
771 using the context of the user being logged off as long as the
772 user's profile is not loaded from within AFS. If the profile
773 was loaded from AFS we can't release the tokens since the Logoff
774 event is triggered prior to the profile being written back to
775 the its source location. This is now performed in an XP SP2
778 * Windows XP SP2 Internet Connection Firewall interoperability
781 * The %WINDIR%\afsdsbmt.ini contains four sections:
782 Submounts, Drive Mappings, Active Maps and CSC Policies.
783 The Submounts and CSC policies are now stored in the registry under
784 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
785 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
786 The Drive Mappings and Active Maps are stored in the registry under
787 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
788 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
790 There is no automatic migration of this data as it would be impossible
791 to consistently migrate data to user profiles which may not be active
792 when the machine is updated.
794 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
795 fake root.afs volume. For the same reasons as for the cellservdb file,
796 this information should not be in %WINDIR%. This information is now
797 kept under the registry key
798 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
800 The data from the afs_freelance.ini file will be automatically
801 migrated to the registry on first execution of afsd_service.exe
803 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
804 troublesome for several reasons. One, it is confusing for those who
805 expect the file to be named "CellServDB" instead of "afsdcell.ini".
806 Two, this file is not a Windows Profile formatted file. Three,
807 applications should not be reading or writing to %WINDIR%. It causes
808 problems for Windows Terminal Server.
810 The new location of CellServDB will be the OpenAFS Client install
811 directory which is by default C:\Program Files\OpenAFS\Client and can
812 be determined by querying the registry for
813 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
815 The existing afsdcell.ini will be migrated by the NSIS installer.
816 The Wix installer must still be updated to do the same.
818 * Change NSIS installer to use DNS by default; to remove Integrated Logon
819 High Security mode; and to add Terminal Services compatibility registry
820 entries to allow the OpenAFS tools to find the afsdcell.ini and other
821 configuration files in %WINDIR%.
823 * Add support for authenticated SMB connections. This will remove
824 the need for high security mode in most situations. Both NTLM
825 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
826 only NTLM can be used even though Kerberos is now supported. The
827 reason is that it is not possible to construct a service principal
828 which is unique to each individual machine.
830 SMB Extended Auth does not work on XP SP2 unless one of two registry
831 modifications are made:
833 (1) To disable the check for matching host names on loopback connections
834 set this key. This does not require a reboot:
836 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
837 "DisableLoopbackCheck"=dword:00000001
839 (2) To add the AFS SMB/CIFS service name to an approved list. This
840 does require a reboot:
842 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
843 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
845 afsd_service.exe will automatically add the current Netbios Name
846 to the BackConnectionHostNames list and then temporarily disable
847 the loopback check for one cycle of startup/shutdown of the service.
848 We assume most folks do not start/stop without a reboot so this
849 will be adequate in most cases.
851 * Fix security hole in afslogon.dll which allowed passwords to be
852 sent in clear text to the KDC in a misformed principal name.
854 * Fix cm_GetCell() to properly handle expired dns entries
857 * If Freelance mode is active and the afs_freelance.ini
858 file does not exist, do not create an empty file.
859 Instead create a file containing ro and rw mountpoints
860 to the default cell using the standard conventions.
862 * Modify the Freelance support to handle the ability
863 to create rw mount points in the fake root.afs volume.
865 * Changed the RPC mechanism used for token setting from
866 named pipes to local. Use of named pipes can be restored
867 by setting the environment variable AFS_RPC_PROTSEQ to
870 Named pipes were required when a Windows 9x system was
871 using a NT system in gateway mode which is incompatible
872 with our use of local loopback adapters.
874 * In afscreds.exe, if a username of the form user@REALM is
875 specified and no password is specified, do not perform a
876 kinit operation. Only perform the aklog functionality.
878 * Add a new registry value which allows the number of processors
879 on which afsd_service.exe executes to be restricted. Valid
880 values are 1..numOfProcessors
882 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
886 * A second MSI based installer option is now available.
888 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
889 request tickets for user/instance@REALM instead of just user@REALM
891 * Modify the Power Management Notify routine to wait for the Hard Dead
892 timeout period instead of a fixed 19 seconds. With the longer timeout
893 periods Hibernation and Standby could never succeed when network
894 connectivity is not available.
896 * The following fs.exe commands are now restricted to Administrator:
897 - checkservers with a non-zero timer value
900 - sysname with a new sysname list
909 setting the default sysname for a machine should be done via the
910 registry and not via "fs sysname".
912 * NSIS installer adds options to install Debugging Symbols
913 and the Microsoft Loopback Adapter; the user is now also
914 given the ability to select the afscreds.exe startup options.
916 * Build system modified to generate symbols for FREE (aka RELEASE)
917 builds as well as CHECKED (aka DEBUG) builds
919 * Sites which have a volume ID of 0x20000001 assigned to their
920 root.cell volumes have been experiencing problems with accessing
921 the root.cell volume of their cell when Freelance mode has been
922 active. This was because 0x20000001 was assigned to the fake
923 root.afs volume created by freelance. The fake volume id is
924 now set to 0x00000001 to prevent conflicts.
926 * The timeout logic in the AFS Client Service has been wrong
927 for sometime. It is based on two different assumptions.
928 First, the SMB client timeout is a fix value as was the case
929 with OS/2 Lan Manager. This assumption is incorrect. The
930 SMB timeout in Windows is a dynamic value computed based upon
931 a fixed minimum timeout to which is added time based upon the
932 size of the request and the performance characteristics of
933 the connection. Second, it is the responsibility of the
934 SMB Server to enforce the timeout requirements of the client.
935 This is untrue. The SMB Server cannot be expected to know
936 the requirements of the client. More importantly, if the
937 SMB server uses the SMB client timeout as a value to restrict
938 its behavior as an RX client, the performance characteristics
939 of the local SMB session would be used to prematurely terminate
940 WAN connections with significantly different performance
943 The timeout logic has therefore been modified in the following
945 . the Lan Manager Workstation (SMB) Session Timeout is used only
946 as a basis for configuring the Connection Dead Timeout
947 and Hard Dead Timeout values. The Connection Dead Timeout
948 must be at least 15 seconds longer than the SMB Timeout
949 and the Hard Dead Timeout must be at least double the
950 Connection Dead Timeout.
951 . New registry entries have been added to allow the Connection
952 Dead Timeout and Hard Dead Timeout values independent of the
953 Lan Manager Workstation Session Timeout
954 . The test to enforce the SMB Client Timeout has been removed.
956 One of the side-effects of removing the enforcement of the SMB
957 Client Timeout is that regardless of whether or not the SMB client
958 is available to receive the response (and how would the SMB server
959 know) the RX protocol response can be used to update the AFS
960 Client Service state for ready access by future SMB client
963 This should be the end of the "Server paused or restarting messages"
965 * Add support for arbitrary UNC paths to the pioctl() support.
966 This enables the fs commands as well as the AFS Shell Extension
967 to work correctly when UNC paths are being used.
969 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
970 DNS if the cell configuration cannot be determined via CellServDB
972 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
973 are ever set more than once at a time
975 * Fix the management of lists of cm_cell_t structures when using
976 DNS to lookup cell information. The previous code would fail to
977 reuse the same cellID for a cell if DNS was used more than once
978 for a given cell name. When the ttl expired, a single cm_cell_t
979 could be inserted into the cm_allCellsp list more than once
980 producing a loop. In addition, the vlServerp list belonging to
981 the cell was not freed resulting in improper refCounting of the
984 * Add DNS support to cm_IoctlNewCell() which previous only examined
987 * Add cm_FreeServer() function and call it from cm_FreeServerList()
988 to properly garbage collect cm_server_t objects
990 * Add numVCs variable to smb.c to track the number of smb_vc_t
991 objects created and use it to initialize the vcID field which
992 previously was set to 0 in all objects resulting in FindByID
995 * Fixed DNS lookups to work consistently throughout the OpenAFS
996 product instead of just from within the afsd_service.exe
998 * Added a runtime check to ensure that AFS Client Service SMB
999 Server is accepting connections before attempting to mount
1002 * Read IP addresses for volume servers out of the CellServDB
1003 file if gethostbyname() on the hostname fails.
1005 * Fix getcellconfig() to populate both the Hostnames as well
1006 as IP addresses when loading cell data via DNS
1008 * Increase the Connection Dead Time to 50 from 20 seconds
1009 Increase the Hard Dead Time to 120 from 40 seconds
1010 (matches the Unix values)
1012 * Fixed an assertion validating the number of allocated NCBs
1014 * Fixed the build environment to consistently build for
1015 Windows 2000 and above. (APPVER = 5.0)
1017 * Fixed rx_debug to properly validate the receipt in incoming
1018 data with select() and recvfrom(). Do not copy data out of
1019 the socket buffer unless success is indicated.
1022 * afsd_service.exe will now display a message box to the
1023 desktop when it terminates due to an IP Address Change.
1025 * installer no longer deletes AFS Server configuration data
1028 * installer generates a warning dialog if the RPC service
1029 is not properly configured
1031 * installer compressed with lzma instead of bzip2
1033 * afsd_service.exe shutdown crash solved once and for all
1035 * reference counting of smb_vc_t data structures improved
1037 * name space collision of smb_fid_t event objects corrected
1039 * the output of "fs memdump" is now written to
1040 %WINDIR%\TEMP\afsd_alloc.log
1042 * the file TaAfsApp_1033.dll is now properly installed allowing
1043 the User Manager to start
1045 * a new algorithm is used for computing filename pattern matches
1047 * afscreds.exe now accepts user names containing instance
1050 * Fix the Directory Name Lookup Cache to be case-sensitive.
1051 This is crucial in environments in which a Windows client
1052 is accessing a directory with more than one filename that
1053 differs only by case. If the directory contains "FOO"
1054 and "Foo". You want "DEL Foo" to delete the correct one.
1055 We still have a problem in that "DEL foo" will delete a
1056 random filename. This will be addressed in a future release.
1058 * Fix afscreds.exe -M option (renewMaps) to work when High
1059 Security mode is off. Also, remember to disable the ActiveMap
1060 flag in afsdsbmt.ini when a drive mapping is removed.
1062 * Updates to NSIS installer script. AFS Server configuration
1063 data will not be destroyed on un-install or re-install.
1064 Use a better compression algorithm.
1066 * afslogon.dll now uses KFW to obtain tokens when available
1068 * afslogon.dll when given an all uppercase username will
1069 attempt to authenticate with both the uppercase name
1070 and an all lowercase variation
1072 * DST modification removed. The fix appears to make things
1073 worse after a reboot of the machine.
1075 * fs.exe: added "cscpolicy" which is used to
1076 change client side caching policy for AFS shares
1078 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1079 [-documents] [-disable] [-help]
1081 * Several uninitialized variables have been initialized
1083 * It is now possible to obtain tokens using cross realm
1084 Kerberos within afscreds.exe:
1086 user: jaltman@ATHENA.MIT.EDU
1088 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1089 will will in turn be used to obtain afs@DEMENTIA.ORG.
1090 The resulting token will be stored with the display name
1091 jaltman@ATHENA.MIT.EDU@dementia.org
1093 * aklog.exe has been added to the client
1095 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1096 [[-p | -path] pathname]
1100 -d gives debugging information.
1101 krb_realm is the kerberos realm of a cell.
1102 pathname is the name of a directory to which you wish to authenticate.
1103 -noprdb means don't try to determine AFS ID.
1104 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1105 (default is Kerberos V)
1106 No commandline arguments means authenticate to the local cell.
1109 * All of the resource files have been restructured to adhere to
1110 a set of rules IBM implemented for loading string resources.
1111 These rules had either been forgotten or were not discovered
1112 by folks working on the OpenAFS sources. The end result was
1113 memory corruption. This is primary item which was preventing
1114 the AFS Server from working.
1116 * Increased the size of the maximum ticket size stored in a token
1117 from 344 bytes to 12,000. Increased the buffers used to convey
1118 messages between the pioctl() caller and the SMB Server from
1119 1000 bytes to 12,512. The code appeared to have been writing
1120 above the top of the stack by quite a few number of bytes.
1121 (The increased ticket size is necessary for the next item.)
1123 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1124 Instead the raw Kerberos 5 ticket is used in its entirety. This
1125 is extremely important as it allows us to use pure Kerberos 5 KDCs
1126 as the source of the AFS authentication. The use of up to 12,000 byte
1127 tickets will allow tickets produced by all versions of Microsoft
1128 Active Directory to be used.
1129 - create a user account.
1130 - designate it DES only
1132 - specify its UPN to be "afs@realm"
1133 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1135 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1136 is special when using long file names. (you must use "*.*" and not "*")
1137 Instead only enforce it when performing 8dot3 searches.
1139 * Fixed the DST problem with creation times being set one hour ahead
1141 * Fixed the problem when using \\afs\cell-alias. For example,
1142 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1143 for the alias name; instead simply expand the name. One of the
1144 symptoms of this problem was a loss of acquired tokens.
1146 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1147 of strings. (Only English strings provided.)
1149 * Fixed the installer to properly replace in use files.
1151 * Fixed the build system to cleanup generated component version files
1153 * The release build compiled with MSVC 6.0 compiler to avoid the
1154 afsd_service.exe shutdown crash. This does not solve the problem
1155 but simply avoids it for the time being.
1159 * fix afslogon.dll to not corrupt memory when High Security mode
1162 * fix afsd_service.exe to not attempt to restore the stack when
1163 an exception occurs. (not safe in multi-threaded programs)
1165 * fix uninstaller to properly remove the CRT and MFC DLLs
1167 * remove a Message Box from afscreds.exe when getcellconfig()
1168 fails on a kerberos realm which is not a cell
1170 The following is a list of changes to the OpenAFS for Window client
1173 * "fs setserverprefs" will leave afsd service deadlocked
1175 * "vos listaddrs" will core dump
1177 * installer sets the appropriate keys to support Integrated Logon
1179 * installer disables the "Find Lana by Name" functionality as it
1180 was causing headaches for many users
1182 * fix the intermittent crash of the power management thread when
1183 shutting down the AFS Client Service
1185 * optimizes the obtain drive mount list functionality which is
1186 executed every time the mount tab in afscreds.exe and afs_config.exe
1187 are refreshed. (this happens a lot)
1189 * fix the service shutdown logic. add the STOP_PENDING state
1190 and do not accept additional service events after we declare
1193 The following is a list of changes to the OpenAFS for Window client
1196 * flexelint was run against the source tree and hundreds (perhaps
1197 thousands) of corrections were applied to ensure prototypes
1198 were in use; types were used consistently; variables were
1199 initialized; unused variables were removed; etc.
1201 * A wide variety of instrumentation was added including the
1202 ability to produce a stack trace from within afsd_service.exe
1205 * Dynamic configuration of the RDRtimeout value based upon the
1206 LanMan Workstation Session Timeout
1208 * The mount root no longer needs to be called "/afs". This
1209 is now set by a registry value "MountRoot" within the key
1210 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1212 * The cell list is now only read out of afsdcell.ini when the
1213 file changes instead of each time a cell is resolved.
1215 * Thread synchronization was added to cm_server.c and ktc_nt.c
1217 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1218 calloc()/free(). The Global functions were needed on Windows 3.x
1219 but have caused a variety of problems on the Win32 platforms.
1220 Avoiding them is highly recommended by several Microsoft
1221 Knowledgebase articles
1223 * Support for Symbolic Links added to the AFS Shell Extension
1225 * Added a registry value "OverlayEnabled" to determine if
1226 Shell Extension Overlays should be enabled.
1227 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1229 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1230 separate trees for checked and free builds. Build system supports
1231 a custom directory src\WINNT\extra which can be used as a grafting
1232 location of organization specific additions to the build tree.
1234 * New installer built using NSIS 2.0.
1236 * Named all kernel objects in order to allow them to be monitored
1237 with tools such as SysInternals' ProcExp.exe.
1239 * Introduced new EventLog framework for AFSD
1241 * Introduced Power Management interface to AFSD for Standby and
1242 Hibernate modes to allow cache to be flushed prior to network
1245 * Utilize Win32 DNSQuery API instead of internal routines. This
1246 allows DNS SRV queries to be sent to all current domain name
1247 servers. Not just one specified in an INI file. DNS is now
1250 * "NetbiosName" registry value may be used to specify a fixed
1251 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1252 when the loopback adapter is in use. If you need to use the
1253 old notation with a loopback adapter installed specify a registry
1256 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1258 * Refactor all modules which depend on LAN Adapter and NetbiosName
1259 determination in a new library: lanahelper.lib. This allows for
1260 consistent behavior throughout the product.
1262 * Move the afsd.log and afsd_init.log files to the directory specified
1263 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1264 for services. Added the Date to the log entries.
1266 * New registry value "RxMaxMTU" used to limit the size of the RX
1267 packets sent by the AFS Client Service to the Server. In order
1268 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1269 size must be restricted to 1264 or smaller. The latest NSIS
1270 installer sets a value of 1260 by default.
1272 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1273 packets. This is not needed in order to work across the Cisco
1274 VPN but might be needed for other network environments. This
1275 value is not set by the NSIS installer.
1277 * New registry value "HideDotFiles" is used to apply the Hidden
1278 attribute to files whose names begin with a '.'. This value
1279 is set by the NSIS installer.
1281 * New registry value "MaxMpxRequests" allows the maximum number
1282 of multiplexed sessions to be configured at run time. This
1283 value is not set by the NSIS installer. The default value is
1286 * New registry value "MaxVCPerServer" allows the maxmimum number
1287 of VCs per server to be configured at run time. This value is
1288 not set by the NSIS installer. The default value is 100.
1290 * New registry value "AllSubmount" allows the "all" submount to
1291 be disabled by setting its value to 0x00.
1293 * Allow cells names to be valid mount points
1294 \\<netbiosName>\<cellname>
1296 * Store the active state of drive mappings in order for afscreds.exe
1297 to restore them upon startup
1299 * Add exception handling to generate a Stack Trace to the afsd_init.log
1300 file if one happens to occur.
1302 * Add lots of logging to help detect the cause of invalid SMB packets
1304 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1305 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1306 renewal of expiring tokens as long as afscreds.exe is running.
1308 * New afscreds.exe command line options:
1310 -M = renew drive maps
1311 -N = ip address change detection
1314 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1315 determines whether or not MIT Kerberos for Windows should be used
1316 to obtain tokens via Kerberos 5 tickets.
1318 * New registry value "AfscredsShortcutParams" in
1319 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1320 determines the command line parameters to be specified when "fixing"
1321 the AFS Shortcut in the user's startup folder.
1323 * The "ShowTrayIcon" registry value has been moved from
1324 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1325 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1327 * The <cell name> registry values used to store the token expiration
1328 reminders have been moved from
1329 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1330 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1332 * Obtain the Logon User Name from the Explorer key when available
1334 * new text document doc\txt\winnotes\registry.txt lists all registry
1335 values used by OpenAFS (excluding the AFS Server)
1337 * BUG: rx_securityClass objects were not properly reference
1338 counted and were never freed.
1340 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1341 would be generated. The existence of a server does not imply
1342 that it is not down. If all of the servers for a cell are down
1343 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1346 * BUG: the directory name lookup cache failed to free the entries
1347 in the cache when the name cache entries cycled. The entries
1348 in the cache would become dereferenced without being freed.
1350 * BUG: fs setserverprefs could be executed without Administrator
1353 * BUG: the number of allocated NCB objects (100) exceeded the number
1354 which could actually be waited upon by the kernel (64). Any objects
1355 which were utilized above the limit could never have event completions
1358 * BUG: smb_username_t objects were not being reference counted and
1359 were not properly freed.
1361 * BUG: smb_tid_t objects could under unusual circumstances be freed
1362 before they were no longer referenced.
1364 * BUG: smb_fid_t object pointer were frequently used even when
1365 their value could be NULL. They were not properly released and
1366 therefore they were never freed.
1368 * BUG: smb_packet_t data structures were not completely initialized
1371 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1372 Denied" because that causes the Explorer Shell to try again until
1373 access is obtained. Instead return "Remote Resources" which allows
1374 the shell to move on and treat the error as transient.
1376 * BUG: when initializing the NCBreturns structure, separate Event objects
1377 were created for each NCB although a single Event object was supposed
1378 to be shared by all.
1380 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1383 * BUG: smb_tran2Packet_t objects were not being properly referenced
1386 * BUG: directory path creation did not handle the case of multiple
1387 directories requiring creation in one attempt
1389 * BUG: SMB requests which required an Extended Response were ignored.
1390 This prevented some files from being written to AFS volumes.
1392 * BUG: character strings were being freed even after they were
1393 inserted into in use data structures
1395 * BUG: inconsistent usernames were used when High Security mode was
1396 enabled. (there is still much to do in this area)
1398 * BUG: pioctl() calls which require out of band RPC operations were
1399 susceptible to race conditions when performed by multiple processes
1401 * BUG: memory allocation and deallocation crossed instances of the
1402 C Runtime Library producing memory leakage and corruption in
1403 afscreds and the client configurator.
