2 * Added a script command to the msi installer "afs_replace"
3 which can be used to replace one version of OpenAFS with
4 another without requiring an uninstall and reinstall if
5 the installed msi is no longer in its original location.
7 * Apparently the problem with multi-domain forests with cross-
8 realm trusts to non-Windows realms was not entirely solved.
9 The authentication to the AFS SMB service failed because
10 the wrong name was being used. Using ASU as an example,
11 the authentication was being performed with the name
12 "QAAD\user" (an account in the forest root) and not
13 "user@ASU.EDU (the MIT Kerberos principal used to login with)
15 The solution was to add an additional dependency on KFW
16 in order or to be able to easily obtain the client principal
17 name stored in the MSLSA ccache TGT. This information is
18 used in two locations:
20 - the pioctl() function
22 - a new WinLogon Event Handler for the "logon" event.
24 The pioctl function will now be able to use the correct
25 name when calling WNetAddConnection2() and the "logon"
26 event handler will now be able to call WNetAddConnection2().
27 The hope is that the "logon" event handler will be called
28 before the profile is loaded but I have not guarrantee
32 * Fixed a locking error in cm_TryBulkStat() which had the
33 potential of deadlocking the system for the length of time
34 it takes to perform a bulk status fetch operation.
36 * Replaced time conversion code (UnixTime <-> FILETIME) to
37 be completely arithmetic instead of relying on a bizarre
38 algorithm involving a variety of C RTL time functions.
39 This has the side effect that UnixTime and FILETIME which
40 are both stored in UTC are interpretted as UTC throughout
41 the year. Windows will apply the same localization to AFS
42 as it does to NTFS. Applications which rely on the ability
43 to sync files between the two file systems will no longer
44 see the timestamps of files in AFS change an hour relative
45 to the files stored in NTFS or Windows based backup devices.
47 * Fixed a invalid memory access under a bizarre circumstance.
48 Windows will allow a physical mass media device to be
49 installed via Plug N Play to the system and will assign it
50 the lowest available drive letter. This is true even if the
51 drive letter is currently assigned in the user session to
52 a network device via NET USE (or its equivalent.) When this
53 happens, queries sent to the CIFS server will contain invalid
54 data. This invalid data was not being caught by the AFS
55 Client Service and was resulting in a crash when Freelance
58 * Fixed a reference count error when registering callbacks
59 on a stat cache object if the callback was already registered
61 * Add a case to cm_Analyze() in order to handle the case where
62 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
63 the server list for the volume is empty. In this case, force
64 an update of the volume info and retry.
66 * Insert a missing cm_EndCallbackGrantingCall() which could
67 result in threads waiting for a callback to complete to never
70 * In the persistent cache, there is a maximum number of volume
71 entries. Allow volume entries to be reused if the maximum
72 number have been allocated and their reference count is zero.
74 * If we already have a dead virtual connection object, don't
75 ignore the fact that additional dead vc objects must be taken
78 * Removed a deadlock condition introduced in the summer of 2004.
79 Do not hold mx locks around calls to RX functions including
80 rx_NewCall(). That is what reference counts on the rx_connection
83 * Fixed an initialization error in afslogon.dll which could
84 result in random behavior including a failure to terminate
85 the NPLogon function. (1.3.80b)
87 * Fixed an error preventing the use of SMB authentication
88 on Windows 2000. (1.3.80a)
91 * Updated CellServDB to Public CellServDB 16 Mar 2005
93 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
94 misinterpretted as "csail.mit.edu" when the resolver
95 is configured to append ".mit.edu" to failed DNS queries.
97 * Fixed another case in which the client would replace connections
98 to the host when it was not necessary. In this case the
99 situation would occur if cryptall was on and the connections
100 were unauthenticated due to lack of an appropriate token.
102 * OpenAFS for Windows has failed to work at sites which are
103 utilizing a cross-realm trust between an MIT/Heimdal realm
104 and a multi-domain Windows forest when the workstation being
105 accessed is not located in the root domain. This is caused
106 by a bug in the workstation which was triggered after the
107 introduction of Windows 2003 Server. When the bug is triggered,
108 the workstation attempts to authenticate users to afsd_service.exe
109 by contacting the Domain Controller instead of using the
110 LSA loopback authentication mechanism.
112 One of the reasons this bug occurs is because the workstation
113 does not have a reliable way of knowing that the service whose
114 netbios name is "AFS" is located on the workstation. This will
115 be fixed starting in Longhorn Beta 1 by Microsoft. The
116 "BackConnectionHostNames" registry value will be used to
117 indicate that the authentications to that service name should
118 be performed using the loopback authentication mechanism.
120 In the meantime, when Logon Caching is enabled, we can force
121 afsd_service.exe to authenticate using the logon cache before
122 contacting the Domain Controller. This will work with both
123 password and smart card based logons.
125 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
126 flag should not be cleared if a volume's server reference is
127 marked as "offline". In the case where all of the volume's
128 servers are either "down" or the volumes are "offline", we want
129 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
130 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
131 should never occur in practice.
133 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
134 5 seconds, clear the server down and volume busy flags, and
135 then force an update from the VLDB. This allows the client to
136 update the location of a volume if the reason for it being
137 marked offline is because it is being moved. Calls to
138 cm_ConnByMServers() will be retried either until success or
139 the RDRtimeout period is reached.
141 * Correct the Power Management code behavior in response to
142 Standby, Suspend, and Shutdown events. Instead of flushing the
143 buffers associated with the mounted SMB submounts, simply write
144 all buffers which are marked dirty.
146 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
147 provides a list of cells other than the default cell for which
148 tokens should be obtained using the default Kerberos principal.
149 This functionality is logon domain specific and is only available
150 when using KFW for authentication.
152 * Fixed FindNext Invalid Handle error caused by over agressive
153 attempts at garbage collecting dirSearch entries when the
154 dirSearch ID wraps from the maximum value to 1.
156 * Add support for registry defined server preferences for VLDB and
157 File servers. See registry.txt for details.
159 * Increased default cache size to 96MB and default number of cache
162 * Fixed refCount leaks related to directory lookups and pioctl calls.
164 * Callbacks revoked during a race condition with an attempt to
165 obtain the same callback no longer result in an inaccessible
168 * New command line tool:
170 afsdacl : Set or reset the DACL to allow starting or stopping
171 the afsd service by any ordinary user.
173 Usage : afsdacl [-set | -reset] [-show]
175 -reset : Reset the DACL
176 -show : Show current DACL (SDSF)
178 * IP addresses are no longer queried once at startup. Instead IP
179 addresses are obtained as needed. Loopback adapter addresses are
180 no longer published to the server.
182 * Pay attention to the MIT KFW registry configuration for automatic
183 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
185 * Fix (once again) case-sensitive comparisons which was apparently
188 * Activate support for vos listvol -format
190 * Population of the "AFS Client Admins" group failed on non-English
191 versions of Windows because the name of the "Administrators" group
192 is localized. Now we lookup the name of the group by using the
193 Administrators Group Alias Relative ID.
195 * Multiple cell token acquisition within afscreds.exe was broken in the
196 case of Kerberos 5 cross realm authentication. Instead of contacting
197 the KDC associated with the cell's realm, afscreds would obtain a
198 token from the KDC of the user's realm. This would result in
199 "invalid kvno errors" while authenticating to the AFS servers.
200 Unauthenticated access would work. The symptoms would vary based upon
201 whether or not the VLDB servers had been contacted using unauthenticated
202 connections prior to the user obtaining tokens.
204 * The list of ACL entries was becoming corrupted. It appears as if
205 an ACL when it expires was not being appropriately cleaned up. In
206 fact, it was left in the list of ACLs associated with the scache
209 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
210 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
211 and "amd64_win64" for amd 64-bit processors.
213 * When executing executables, Windows provides a mechanisms by which
214 the normal search for DLLs can be bypassed. If a file foo.exe is
215 being executed and there exists a file or directory "foo.exe.local"
216 (the contents are ignored if a file), then Windows will search for
217 DLLs first in the "foo.exe.local" directory and second in the
218 directory in which the "foo.exe" file is located.
220 Previous releases of OAFW would improperly return
221 STATUS_NOT_A_DIRECTORY instead of the expected
222 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
223 to terminate the search for the DLL causing the execution of the
226 * Rework the reference counting of smb_vc_t objects. The references
227 stored in the waiting locks were not counted. This could result in
228 an assertion if the reference count drops to zero.
230 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
231 when running in freelance mode.
233 * Added support for persistent caching of file contents, stat entries,
234 volume data, cell data, and name lookup data. When the registry
235 value, "NonPersistentCaching", is not defined or set to 0 the file
236 specified by "CachePath" becomes a persistent cache file. The
237 size of the cache file is computed at run time. It has a maximum
238 size of approximately 1.2GB. The contents of the file will be
239 validated according to the rules specified by the "ValidateCache"
242 * Added support for UUIDs. UUIDs are kept for as long as the
243 cache file is intact.
245 * Added cmdebug.exe and support cache manager debugging callback
246 interfaces in afsd_service.exe.
248 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
249 [-addrs] [-cache] [-help]
250 Where: -long print all info
251 -addrs print only host interfaces
252 -cache print only cache configuration
254 * Symlinks to \\AFS\[all\]... will now be treated the same as
255 symlinks to /afs/.... However, please use /afs/... as otherwise
256 the symlinks won't work on Unix.
258 * Correct a problem with local CellID allocation for cells whose
259 server list is obtained via DNS instead of a CellServDB file. If
260 the DNS information expires the CellID assigned to the entry will
261 be changed. This causes all of the cm_scache_t objects which refer
262 to the old cellID number to become useless. Attempts to access
263 files or directories with cm_scache_t objects using the old cellID
264 will fail since the server list cannot be obtained.
266 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
267 be triggered if the volume referenced by the cm_scache_t object is
270 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
271 in addition to SERVICE_ACCEPT_STOP.
273 * Move RPC shutdown until after the SMB and RX shutdown procedures
274 complete. Block until RPC shutdown is complete.
276 * Modify afslogon.dll (integrated logon) to wait for service if its
277 state is START_PENDING. If the timeout period occurs, reset to
278 the retry interval and not the sleep interval.
280 * When renewing the server list for a cell obtained via DNS AFSDB
281 records, the cm_cell_t entry must be removed from the list of all
282 cells. Otherwise, the list of cells will be corrupted.
284 * In the dcache and scache modules, use the cm_scache_t dataVersion
285 instead of the cm_fakeDirVersion.
287 * Synchronize fs.c with the unix version.
289 * The variable used to determine whether a file or virtual memory
290 mapped cache is used was not properly initialized to a default
291 value. If the registry setting "NonPersistentCaching" was not
292 set, the choice would be random. Properly initialized to be
295 * The memory mapped view was never unmapped before closing the file
296 at service shutdown. This is now properly cleaned up.
298 * Default location of Cache file is now %TEMP%\AFSCache
302 * A bug affecting new installations of 1.3.75/76 would result in
303 the creating of incorrect mountpoints in the freelance root.afs
304 volume for the default cell.
306 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
307 of "root.cell", you have been affected by the bug. To correct the
308 problem, execute the following commands:
310 fs rmmount \\afs\all\<cellname>
311 fs rmmount \\afs\all\.<cellname>
313 fs mkmount \\afs\all\<cellname> root.cell <cellname>
314 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
318 * A bug has been fixed in the auto-generation of Freelance root.afs
319 symlinks which produced random entries in the \\AFS\all directory.
321 * Support has been added for multi-homed servers
324 * Added a new registry value, "StoreAnsiFilenames", which can be used
325 to force the use of ANSI character sets instead of OEM Code Pages.
326 This feature is useful when users require the ability to create
327 filenames with 8-bit characters and need to access the files from
328 both Latin-1 based Unix systems as well as from Windows.
330 Activation of this feature will prevent access to files stored with
331 8-bit OEM characters.
333 * Shutdown all SMB threads in a synchronized manner when stopping the
336 * There is currently a maximum cache size of 1.3GB. The limit is imposed
337 by the largest contiguous block of unused memory within the 2GB process
338 space which can be assigned to the memory mapped file. Unfortunately,
339 when the executable digital signature verification code is activated
340 Windows sees fit to further segment the process memory which in turn
341 reduces the size of the maximum cache file to less then 800MB. If
342 larger cache sizes are desired, a new registry value should be set:
344 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
346 Setting this value will disable the runtime verification of digital
347 signatures on afsd_service.exe and the afs dlls which it loads. It
348 will not disable the the version number check on those same files.
349 The signature verification is not a security messure and is only meant
350 to enhance the ability to afsd_service.exe to detect potential
351 destablizing mixtures of DLLs from incompatible distributions.
353 Added code to auto-disable the signature verification check if
354 the desired cache size is greater then 700MB.
356 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
357 used to verify the validity of the afsd_service.exe binary
358 as well as each of the AFS DLLs loaded by the service. Not only
359 must the digital signature be valid but the signatures of the
360 DLL must be signed by the same entity as the service.
362 * Implement new functions: cm_freelanceMountPointExists and
363 cm_freelanceSymlinkExists. Use them along with other validity
364 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
365 ensure that name collisions do not occur and that empty strings
366 are not valid file names.
368 A symlink may not have a name which would resolve to a valid
369 cell name. Doing so would prevent access to the cell.
371 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
372 re-initialization code. The reference counts of the fake root.afs
373 volume scache object(s) would become invalid when the mount point
374 or symlink lists were altered.
376 * Add registry entries to provide mappings from the afsdsbmt.ini
377 to the new locations for applications which count on the use
378 of the old Profile file APIs. These apps are likely to fail
379 if the user does not have administrator privileges and the
380 registry is locked down.
382 * The afs_config.exe submounts dialog had two errors.
383 First, attempts to remove entries failed because the registry
384 key was being opened without KEY_WRITE privileges.
385 Second, when editing a submount entry, changing the name
386 would add a new key and leave the original one in place.
387 Now the original submount will be removed if its name is
390 * In recent months there have been several incidents in which
391 users have experienced problems starting or accessing
392 afsd_service.exe and after significant effort has been spent
393 it has turned out that they have two versions of AFS on the
394 machine or an inconsistent set of DLLs.
396 Code has now been added to afsd_service.exe which will walk
397 the list of modules loaded by afsd_service.exe and validate
398 that the version of the AFS DLLs matches the version of the
399 afsd_service.exe executable. If they do not match the service
402 * When Freelance mode is enabled and there is no registry
403 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
404 will attempt to import the afs_freelance.ini file contents.
405 If the file does not exist, it was creating a dummy file
406 with a r/o and r/w entry for the default cell and then
407 importing those values.
409 This process has been changed. The temporary file is no
410 longer created. Also, both the OpenAFS Client install
411 directory as well as %WINDIR% are checked for previous
412 afs_freelance.ini files.
414 * Added support for VL_GetEntryByNameN(). Still need to add
415 support for VL_GetEntryByNameU() for multi-homed support.
417 * Fix a deadlock situation in afscreds.exe when canceling an
418 auto-generated Obtain Tokens dialog
421 * Fix the locking of objects during Directory Searches in the
422 SMB/CIFS server. The failure to properly lock the reference
423 counts was resulting in the premature freeing of smb_dirSearch_t
424 objects while they were still in use by the SMB/CIFS client.
425 This does not solve the "Invalid Handle" problem.
427 * Fix Find Cell By Name pioctl call to return a valid cell
428 name for the Freelance fake root.afs volume.
429 "Freelance.Local.Root".
431 * Fix the Explorer Shell Extension Symlinks->Add operation.
432 The dialog template was missing and the link destination
433 string was too short.
435 * Add support for symlinks to Freelance root.afs volume
436 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
437 <number> = "<linkname>:<relative-path>."
438 Use symlink.exe to create, list, or remove
440 * Remove the fallback to the use of KFW's KRB4 library when obtaining
441 tokens. We never obtain KRB4 tickets.
443 * Fix AFS Client Configuration Control Panel to support new SysName
446 * Fix a bug in afsd_service.exe which could result in the SysName
447 not being read from the registry.
450 * Add code to block the issuance of AFS tokens by aklog.exe or
451 afscreds.exe when the Kerberos 5 principal name contains a dot.
453 * Modify the IsAdmin() function to always treat the local SYSTEM
454 account as an AFS client administrator. Affects fs.exe and
457 * Modify the internal handling of Quota Exceeded errors
459 * Upgrade all reference count fields in the Windows cache manager
460 and the osi library to use unsigned long instead of signed short.
461 A similar fix has been applied to the afs rpc (rx) library.
463 * fix the Windows cache manager to prevent it from replacing the
464 rx_connection object associated with the cm_conn_t object on each
465 and every operation if "fs crypt" was set. This explains the
466 dramatic performance difference when crypt is used vs clear.
467 The problem: 'cryptall', a boolean flag indicating whether or not
468 "fs crypt" is set, was being compared to the rx_connection
469 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
470 1 != 2 and therefore the rx_connection was always destroyed
471 and replaced on each and every operation.
473 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
474 It is not safe for the cm_conn_t object to not be locked because
475 rx_DestroyConnection might be called from another thread if:
476 - the user's tokens have changed or expired
477 - the crypt mode has changed
479 This fix appears to have also taken care of the problems associated
480 with Overlapped Writes resulting in Delayed Write errors.
482 * fix NSIS installer's AdminGroup.exe to properly create and
483 remove groups when given -create or -remove. The string comparison
486 * fs sysname now accepts a list of sysname values
488 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
489 DWORD which when set to a non-zero value will cause error message
490 text to be output to stderr from the pioctl() routine. Useful in
491 debugging failures of fs.exe, tokens.exe, etc.
493 * added a test to the power management code to only perform a
494 flush operation if there is at least one network adapter which
495 is not a loopback adapter.
497 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
498 "EnableKFW". This value will not be read if the key
499 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
500 value under that key does not.
502 * provide mechanisms to force the use of krb524d for Kerberos 5
503 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
504 there is a new registry value "Use524" and for aklog.exe a new
505 command line parameter "-m".
507 * Fix the pattern matching algorithm to properly match patterns
510 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
511 which is used by both the original function and the new
512 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
513 creation of HardLinks in addition to Renaming. smb_Link()
514 is a new function which creates HardLinks via cm_Link().
515 cm_Link() is a new vnodeops function which creates links
518 smb_ReceiveNTRename() does not support the File Copy and
519 Move Cluster Information operations described in its interface.
520 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
522 * When opening files via symlinks, we should follow the symlinks
523 until we reach the actual file stat cache entry. The stat cache
524 entry of the file should then be stored in the FID instead of
525 stat scache entry of the symlink.
527 * return bad operation errors for all unimplemented functions
528 even if we do not know the functions exist.
530 * Log bad packets and unknown operation packets to the trace log
532 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
535 * Update list of known CIFS operations to include all those listed
536 in CIFS-TR-1p00_FINAL.pdf.
538 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
539 to support the REG_EXPAND_SZ type.
542 * A new Windows authorization group "AFS Client Admins" is now
543 created and populated with the members of the "Administrators"
544 group. The group is used to determine which accounts on the
545 machine may be used to modify the AFS Client Configuration via
546 the UI and command line tools. afs_config.exe, fs.exe,
548 * Modify the WinLogon Logoff Event Handler to query NT4 domain
549 controllers for the remote profile path if Active Directory
550 services are not available.
552 * Fix aklog.exe to not add the AFS ID to the username
554 * PTS registration of new users to foreign cells has been added to
557 * The cm_Daemon thread is used to perform checks for
558 down servers, up servers, volumes, callback expirations,
559 lock maintenance and token expiration. Due to a gaff in
560 larger integer division the thread never performed any
561 work. Instead the current time computation would always
562 be less then the trigger times. This had an adverse affect
563 on the client's ability to maintain communication with servers,
564 keep volumes up to date, and flush user tokens and acls
565 when they have expired. This was broken when the 1.3 branch
566 was modified to support VC7 which no longer included
569 * An initialization problem with the Freelance code was
570 detected while fixing the callbackRequest. The cm_rootSCachep
571 object is obtained during afsd_InitDaemons() but the callback
572 information is incomplete. The callback information will not
573 be obtained until cm_MergeStatus is called from within
574 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
575 test for the conditions under which the callback information
578 * Reports have been filed indicating that callbacks were
579 being lost. An examination of the code indicated that the
580 cm_server_t objects were not being properly reference
581 counted by the cm_scache_t and cm_callbackRequest_t objects.
582 In particular, the cm_server_t objects may have been freed
583 from beneath the cm_conn_t objects.
585 All of the reference counting is now done via the functions:
590 this improves the ability to track the referrals.
592 Each cm_BeginCallbackGranting Call now allocates a reference
593 to the cm_server_t. The cm_EndCallbackGrantingCall either
594 frees the reference or transfers it to the cm_scache_t
595 cbServerp field. These are then appropriately tracked
596 through the cm_Analyze call.
598 * Ensure that the dnlc hash table is the same size as the
599 dir name hash table (as per original author's note).
600 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
601 for compatibility with 64-bit systems.
603 * fix smb_ApplyV3DirListPatches to properly apply the hidden
604 attribute to dotfiles when the infoLevel < 0x101 and
605 cm_SyncOp has failed.
607 * Fix the Freelance registry initialization code. There
608 was a possibility that some systems could end up with
609 garbage in the registry during a clean install.
612 * file and directory names beginning with "." will now be given the
613 hidden attribute when the volume access is anonymous. this matches
614 the behavior when the volume access is via an authenticated user.
616 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
617 key. When a change occurs mark the root.afs data as invalid and
618 for it to be reloaded on the next access. This allows administrators
619 to modify the mount point list without restarting the service.
621 The freelance client used to provide a fake modification time for
622 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
623 Added code to extract the last modification time of the Freelance
624 registry key and use that instead. The time now represents the
625 most recent mount point change.
627 * PTS registration of new users to foreign cells has been added to
630 * Additional Cache Control and Credential Manager options have been
631 added to the WiX installer. See deployment guide for details.
633 * The CachePath setting is now optionally a REG_EXPAND_SZ type
635 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
638 * The loopback installation code may have had a problem updating the
639 %ETC%\HOSTS file which could have resulted in a premature failure.
640 Work around code has been added for the case where the file cannot
643 * The default max chunksize was increased from 15 (32K) to 17 (128K)
644 because Windows sends 64K blocks when using overlapped writes.
646 * The default number of server threads was increased from 4 to 25 to
647 better handle overlapped writes.
649 * The "AfscredsShortcutParams" registry value was not being properly
650 loaded by afscreds.exe. Therefore, the default value was always being
651 used instead of the value set by the installer.
653 * Windows XP provides downgrade attack detection to prevent an attacker
654 from being able to force the use of NTLM simply by disrupting
655 communication with the KDC. This attack cannot exist between the
656 Windows CIFS client and the AFS Client Service. Therefore, when a
657 downgrade has been detected the afs pioctl library will force the
658 establishment of a new CIFS connection using NTLM.
660 * A locking error was discovered surrounding all references to volume
661 server lists within the cm_cell.c source file.
663 * The logged into Windows username was incorrect on Terminal Server
666 * A new registry value "NonPersistentCaching" was added to the service
667 parameters key. When set to a non-zero value, the afs cache is stored
668 in the Windows paging file. There are two limitations to choosing
670 1. when persistent caching is implemented it won't work with
671 this flag set since there will be nothing to persist.
672 2. with this flag set the initial paging allocation cannot be
673 changed while the service is running
675 * An initialization bug was discovered in aklog.exe which affected users
676 who have a domain name for their afs servers which could not be mapped
680 * afs_config.exe now validates cell names against DNS in addition
681 to the CellServDB file.
683 * In order to allow the freelance client to connect to a volume with ID
684 equal to 1 on the default cell we changed the fake root.afs volume ID
685 once again. This time we choose 0xFFFFFFFF. In addition, we change
686 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
687 It will now be impossible for a volume ID to match that of another
688 cell unless the client is connected to 0xFFFFFFFD cells. That should
689 be enough room for growth.
691 * Fix "fs mkmount" command to work with UNC paths and when
692 started from non-AFS drives. It is now possible to create a mount
693 point in the freelance fake root.afs volume with the command
695 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
699 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
700 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
702 * The algorithm used to re-attempt access to the servers associated with
703 a volume has been altered to properly address the case in which all
704 servers have been marked down. The previous algorithm did not reset
705 the server's down flags so the servers were never actually retried.
706 This caused a problem with active volumes if the network connectivity
707 was lost as could be the case with a network cable removal, wireless
708 drop, or laptop hibernation. With the fix volume access is restored
709 almost instantenously when network connectivity becomes available.
711 * Support for SMB/CIFS browsing has been added to the AFS Client Service
712 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
713 listing of AFS submounts and freelance mount points. Support for
714 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
715 significantly enhances the behavior of AFS volumes within the Explorer
716 Shell. For instance, "AFS" now shows up as server in the Explorer
717 with each submount or freelance mount point visible as a share.
718 The right click menu in each folder now works with full functionality
719 on a consistent basis.
721 * The network provider can be configured to have different behavior
722 depending on the domain that the user logs into. These settings are
723 only relevant when using integrated login. A domain refers to an
724 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
725 local machine (i.e. local account logins). The domain name that is
726 used for selecting the domain would be the domain that is passed into
727 the NPLogonNotify function of the network provider. (see registry.txt
730 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
731 "Authentication Cell" which may be used to specify a default
732 authentication cell for afscreds.exe which is different from
733 the default cell for the AFS Client Service daemon.
735 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
736 afslogon.dll moved to %WINDIR%\System32\.
737 New registry entries added to register the dll for Winlogon events.
739 The logoff event will now force a call to ktc_ForgetAllTokens()
740 using the context of the user being logged off as long as the
741 user's profile is not loaded from within AFS. If the profile
742 was loaded from AFS we can't release the tokens since the Logoff
743 event is triggered prior to the profile being written back to
744 the its source location. This is now performed in an XP SP2
747 * Windows XP SP2 Internet Connection Firewall interoperability
750 * The %WINDIR%\afsdsbmt.ini contains four sections:
751 Submounts, Drive Mappings, Active Maps and CSC Policies.
752 The Submounts and CSC policies are now stored in the registry under
753 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
754 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
755 The Drive Mappings and Active Maps are stored in the registry under
756 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
757 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
759 There is no automatic migration of this data as it would be impossible
760 to consistently migrate data to user profiles which may not be active
761 when the machine is updated.
763 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
764 fake root.afs volume. For the same reasons as for the cellservdb file,
765 this information should not be in %WINDIR%. This information is now
766 kept under the registry key
767 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
769 The data from the afs_freelance.ini file will be automatically
770 migrated to the registry on first execution of afsd_service.exe
772 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
773 troublesome for several reasons. One, it is confusing for those who
774 expect the file to be named "CellServDB" instead of "afsdcell.ini".
775 Two, this file is not a Windows Profile formatted file. Three,
776 applications should not be reading or writing to %WINDIR%. It causes
777 problems for Windows Terminal Server.
779 The new location of CellServDB will be the OpenAFS Client install
780 directory which is by default C:\Program Files\OpenAFS\Client and can
781 be determined by querying the registry for
782 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
784 The existing afsdcell.ini will be migrated by the NSIS installer.
785 The Wix installer must still be updated to do the same.
787 * Change NSIS installer to use DNS by default; to remove Integrated Logon
788 High Security mode; and to add Terminal Services compatibility registry
789 entries to allow the OpenAFS tools to find the afsdcell.ini and other
790 configuration files in %WINDIR%.
792 * Add support for authenticated SMB connections. This will remove
793 the need for high security mode in most situations. Both NTLM
794 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
795 only NTLM can be used even though Kerberos is now supported. The
796 reason is that it is not possible to construct a service principal
797 which is unique to each individual machine.
799 SMB Extended Auth does not work on XP SP2 unless one of two registry
800 modifications are made:
802 (1) To disable the check for matching host names on loopback connections
803 set this key. This does not require a reboot:
805 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
806 "DisableLoopbackCheck"=dword:00000001
808 (2) To add the AFS SMB/CIFS service name to an approved list. This
809 does require a reboot:
811 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
812 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
814 afsd_service.exe will automatically add the current Netbios Name
815 to the BackConnectionHostNames list and then temporarily disable
816 the loopback check for one cycle of startup/shutdown of the service.
817 We assume most folks do not start/stop without a reboot so this
818 will be adequate in most cases.
820 * Fix security hole in afslogon.dll which allowed passwords to be
821 sent in clear text to the KDC in a misformed principal name.
823 * Fix cm_GetCell() to properly handle expired dns entries
826 * If Freelance mode is active and the afs_freelance.ini
827 file does not exist, do not create an empty file.
828 Instead create a file containing ro and rw mountpoints
829 to the default cell using the standard conventions.
831 * Modify the Freelance support to handle the ability
832 to create rw mount points in the fake root.afs volume.
834 * Changed the RPC mechanism used for token setting from
835 named pipes to local. Use of named pipes can be restored
836 by setting the environment variable AFS_RPC_PROTSEQ to
839 Named pipes were required when a Windows 9x system was
840 using a NT system in gateway mode which is incompatible
841 with our use of local loopback adapters.
843 * In afscreds.exe, if a username of the form user@REALM is
844 specified and no password is specified, do not perform a
845 kinit operation. Only perform the aklog functionality.
847 * Add a new registry value which allows the number of processors
848 on which afsd_service.exe executes to be restricted. Valid
849 values are 1..numOfProcessors
851 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
855 * A second MSI based installer option is now available.
857 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
858 request tickets for user/instance@REALM instead of just user@REALM
860 * Modify the Power Management Notify routine to wait for the Hard Dead
861 timeout period instead of a fixed 19 seconds. With the longer timeout
862 periods Hibernation and Standby could never succeed when network
863 connectivity is not available.
865 * The following fs.exe commands are now restricted to Administrator:
866 - checkservers with a non-zero timer value
869 - sysname with a new sysname list
878 setting the default sysname for a machine should be done via the
879 registry and not via "fs sysname".
881 * NSIS installer adds options to install Debugging Symbols
882 and the Microsoft Loopback Adapter; the user is now also
883 given the ability to select the afscreds.exe startup options.
885 * Build system modified to generate symbols for FREE (aka RELEASE)
886 builds as well as CHECKED (aka DEBUG) builds
888 * Sites which have a volume ID of 0x20000001 assigned to their
889 root.cell volumes have been experiencing problems with accessing
890 the root.cell volume of their cell when Freelance mode has been
891 active. This was because 0x20000001 was assigned to the fake
892 root.afs volume created by freelance. The fake volume id is
893 now set to 0x00000001 to prevent conflicts.
895 * The timeout logic in the AFS Client Service has been wrong
896 for sometime. It is based on two different assumptions.
897 First, the SMB client timeout is a fix value as was the case
898 with OS/2 Lan Manager. This assumption is incorrect. The
899 SMB timeout in Windows is a dynamic value computed based upon
900 a fixed minimum timeout to which is added time based upon the
901 size of the request and the performance characteristics of
902 the connection. Second, it is the responsibility of the
903 SMB Server to enforce the timeout requirements of the client.
904 This is untrue. The SMB Server cannot be expected to know
905 the requirements of the client. More importantly, if the
906 SMB server uses the SMB client timeout as a value to restrict
907 its behavior as an RX client, the performance characteristics
908 of the local SMB session would be used to prematurely terminate
909 WAN connections with significantly different performance
912 The timeout logic has therefore been modified in the following
914 . the Lan Manager Workstation (SMB) Session Timeout is used only
915 as a basis for configuring the Connection Dead Timeout
916 and Hard Dead Timeout values. The Connection Dead Timeout
917 must be at least 15 seconds longer than the SMB Timeout
918 and the Hard Dead Timeout must be at least double the
919 Connection Dead Timeout.
920 . New registry entries have been added to allow the Connection
921 Dead Timeout and Hard Dead Timeout values independent of the
922 Lan Manager Workstation Session Timeout
923 . The test to enforce the SMB Client Timeout has been removed.
925 One of the side-effects of removing the enforcement of the SMB
926 Client Timeout is that regardless of whether or not the SMB client
927 is available to receive the response (and how would the SMB server
928 know) the RX protocol response can be used to update the AFS
929 Client Service state for ready access by future SMB client
932 This should be the end of the "Server paused or restarting messages"
934 * Add support for arbitrary UNC paths to the pioctl() support.
935 This enables the fs commands as well as the AFS Shell Extension
936 to work correctly when UNC paths are being used.
938 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
939 DNS if the cell configuration cannot be determined via CellServDB
941 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
942 are ever set more than once at a time
944 * Fix the management of lists of cm_cell_t structures when using
945 DNS to lookup cell information. The previous code would fail to
946 reuse the same cellID for a cell if DNS was used more than once
947 for a given cell name. When the ttl expired, a single cm_cell_t
948 could be inserted into the cm_allCellsp list more than once
949 producing a loop. In addition, the vlServerp list belonging to
950 the cell was not freed resulting in improper refCounting of the
953 * Add DNS support to cm_IoctlNewCell() which previous only examined
956 * Add cm_FreeServer() function and call it from cm_FreeServerList()
957 to properly garbage collect cm_server_t objects
959 * Add numVCs variable to smb.c to track the number of smb_vc_t
960 objects created and use it to initialize the vcID field which
961 previously was set to 0 in all objects resulting in FindByID
964 * Fixed DNS lookups to work consistently throughout the OpenAFS
965 product instead of just from within the afsd_service.exe
967 * Added a runtime check to ensure that AFS Client Service SMB
968 Server is accepting connections before attempting to mount
971 * Read IP addresses for volume servers out of the CellServDB
972 file if gethostbyname() on the hostname fails.
974 * Fix getcellconfig() to populate both the Hostnames as well
975 as IP addresses when loading cell data via DNS
977 * Increase the Connection Dead Time to 50 from 20 seconds
978 Increase the Hard Dead Time to 120 from 40 seconds
979 (matches the Unix values)
981 * Fixed an assertion validating the number of allocated NCBs
983 * Fixed the build environment to consistently build for
984 Windows 2000 and above. (APPVER = 5.0)
986 * Fixed rx_debug to properly validate the receipt in incoming
987 data with select() and recvfrom(). Do not copy data out of
988 the socket buffer unless success is indicated.
991 * afsd_service.exe will now display a message box to the
992 desktop when it terminates due to an IP Address Change.
994 * installer no longer deletes AFS Server configuration data
997 * installer generates a warning dialog if the RPC service
998 is not properly configured
1000 * installer compressed with lzma instead of bzip2
1002 * afsd_service.exe shutdown crash solved once and for all
1004 * reference counting of smb_vc_t data structures improved
1006 * name space collision of smb_fid_t event objects corrected
1008 * the output of "fs memdump" is now written to
1009 %WINDIR%\TEMP\afsd_alloc.log
1011 * the file TaAfsApp_1033.dll is now properly installed allowing
1012 the User Manager to start
1014 * a new algorithm is used for computing filename pattern matches
1016 * afscreds.exe now accepts user names containing instance
1019 * Fix the Directory Name Lookup Cache to be case-sensitive.
1020 This is crucial in environments in which a Windows client
1021 is accessing a directory with more than one filename that
1022 differs only by case. If the directory contains "FOO"
1023 and "Foo". You want "DEL Foo" to delete the correct one.
1024 We still have a problem in that "DEL foo" will delete a
1025 random filename. This will be addressed in a future release.
1027 * Fix afscreds.exe -M option (renewMaps) to work when High
1028 Security mode is off. Also, remember to disable the ActiveMap
1029 flag in afsdsbmt.ini when a drive mapping is removed.
1031 * Updates to NSIS installer script. AFS Server configuration
1032 data will not be destroyed on un-install or re-install.
1033 Use a better compression algorithm.
1035 * afslogon.dll now uses KFW to obtain tokens when available
1037 * afslogon.dll when given an all uppercase username will
1038 attempt to authenticate with both the uppercase name
1039 and an all lowercase variation
1041 * DST modification removed. The fix appears to make things
1042 worse after a reboot of the machine.
1044 * fs.exe: added "cscpolicy" which is used to
1045 change client side caching policy for AFS shares
1047 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1048 [-documents] [-disable] [-help]
1050 * Several uninitialized variables have been initialized
1052 * It is now possible to obtain tokens using cross realm
1053 Kerberos within afscreds.exe:
1055 user: jaltman@ATHENA.MIT.EDU
1057 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1058 will will in turn be used to obtain afs@DEMENTIA.ORG.
1059 The resulting token will be stored with the display name
1060 jaltman@ATHENA.MIT.EDU@dementia.org
1062 * aklog.exe has been added to the client
1064 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1065 [[-p | -path] pathname]
1069 -d gives debugging information.
1070 krb_realm is the kerberos realm of a cell.
1071 pathname is the name of a directory to which you wish to authenticate.
1072 -noprdb means don't try to determine AFS ID.
1073 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1074 (default is Kerberos V)
1075 No commandline arguments means authenticate to the local cell.
1078 * All of the resource files have been restructured to adhere to
1079 a set of rules IBM implemented for loading string resources.
1080 These rules had either been forgotten or were not discovered
1081 by folks working on the OpenAFS sources. The end result was
1082 memory corruption. This is primary item which was preventing
1083 the AFS Server from working.
1085 * Increased the size of the maximum ticket size stored in a token
1086 from 344 bytes to 12,000. Increased the buffers used to convey
1087 messages between the pioctl() caller and the SMB Server from
1088 1000 bytes to 12,512. The code appeared to have been writing
1089 above the top of the stack by quite a few number of bytes.
1090 (The increased ticket size is necessary for the next item.)
1092 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1093 Instead the raw Kerberos 5 ticket is used in its entirety. This
1094 is extremely important as it allows us to use pure Kerberos 5 KDCs
1095 as the source of the AFS authentication. The use of up to 12,000 byte
1096 tickets will allow tickets produced by all versions of Microsoft
1097 Active Directory to be used.
1098 - create a user account.
1099 - designate it DES only
1101 - specify its UPN to be "afs@realm"
1102 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1104 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1105 is special when using long file names. (you must use "*.*" and not "*")
1106 Instead only enforce it when performing 8dot3 searches.
1108 * Fixed the DST problem with creation times being set one hour ahead
1110 * Fixed the problem when using \\afs\cell-alias. For example,
1111 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1112 for the alias name; instead simply expand the name. One of the
1113 symptoms of this problem was a loss of acquired tokens.
1115 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1116 of strings. (Only English strings provided.)
1118 * Fixed the installer to properly replace in use files.
1120 * Fixed the build system to cleanup generated component version files
1122 * The release build compiled with MSVC 6.0 compiler to avoid the
1123 afsd_service.exe shutdown crash. This does not solve the problem
1124 but simply avoids it for the time being.
1128 * fix afslogon.dll to not corrupt memory when High Security mode
1131 * fix afsd_service.exe to not attempt to restore the stack when
1132 an exception occurs. (not safe in multi-threaded programs)
1134 * fix uninstaller to properly remove the CRT and MFC DLLs
1136 * remove a Message Box from afscreds.exe when getcellconfig()
1137 fails on a kerberos realm which is not a cell
1139 The following is a list of changes to the OpenAFS for Window client
1142 * "fs setserverprefs" will leave afsd service deadlocked
1144 * "vos listaddrs" will core dump
1146 * installer sets the appropriate keys to support Integrated Logon
1148 * installer disables the "Find Lana by Name" functionality as it
1149 was causing headaches for many users
1151 * fix the intermittent crash of the power management thread when
1152 shutting down the AFS Client Service
1154 * optimizes the obtain drive mount list functionality which is
1155 executed every time the mount tab in afscreds.exe and afs_config.exe
1156 are refreshed. (this happens a lot)
1158 * fix the service shutdown logic. add the STOP_PENDING state
1159 and do not accept additional service events after we declare
1162 The following is a list of changes to the OpenAFS for Window client
1165 * flexelint was run against the source tree and hundreds (perhaps
1166 thousands) of corrections were applied to ensure prototypes
1167 were in use; types were used consistently; variables were
1168 initialized; unused variables were removed; etc.
1170 * A wide variety of instrumentation was added including the
1171 ability to produce a stack trace from within afsd_service.exe
1174 * Dynamic configuration of the RDRtimeout value based upon the
1175 LanMan Workstation Session Timeout
1177 * The mount root no longer needs to be called "/afs". This
1178 is now set by a registry value "MountRoot" within the key
1179 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1181 * The cell list is now only read out of afsdcell.ini when the
1182 file changes instead of each time a cell is resolved.
1184 * Thread synchronization was added to cm_server.c and ktc_nt.c
1186 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1187 calloc()/free(). The Global functions were needed on Windows 3.x
1188 but have caused a variety of problems on the Win32 platforms.
1189 Avoiding them is highly recommended by several Microsoft
1190 Knowledgebase articles
1192 * Support for Symbolic Links added to the AFS Shell Extension
1194 * Added a registry value "OverlayEnabled" to determine if
1195 Shell Extension Overlays should be enabled.
1196 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1198 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1199 separate trees for checked and free builds. Build system supports
1200 a custom directory src\WINNT\extra which can be used as a grafting
1201 location of organization specific additions to the build tree.
1203 * New installer built using NSIS 2.0.
1205 * Named all kernel objects in order to allow them to be monitored
1206 with tools such as SysInternals' ProcExp.exe.
1208 * Introduced new EventLog framework for AFSD
1210 * Introduced Power Management interface to AFSD for Standby and
1211 Hibernate modes to allow cache to be flushed prior to network
1214 * Utilize Win32 DNSQuery API instead of internal routines. This
1215 allows DNS SRV queries to be sent to all current domain name
1216 servers. Not just one specified in an INI file. DNS is now
1219 * "NetbiosName" registry value may be used to specify a fixed
1220 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1221 when the loopback adapter is in use. If you need to use the
1222 old notation with a loopback adapter installed specify a registry
1225 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1227 * Refactor all modules which depend on LAN Adapter and NetbiosName
1228 determination in a new library: lanahelper.lib. This allows for
1229 consistent behavior throughout the product.
1231 * Move the afsd.log and afsd_init.log files to the directory specified
1232 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1233 for services. Added the Date to the log entries.
1235 * New registry value "RxMaxMTU" used to limit the size of the RX
1236 packets sent by the AFS Client Service to the Server. In order
1237 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1238 size must be restricted to 1264 or smaller. The latest NSIS
1239 installer sets a value of 1260 by default.
1241 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1242 packets. This is not needed in order to work across the Cisco
1243 VPN but might be needed for other network environments. This
1244 value is not set by the NSIS installer.
1246 * New registry value "HideDotFiles" is used to apply the Hidden
1247 attribute to files whose names begin with a '.'. This value
1248 is set by the NSIS installer.
1250 * New registry value "MaxMpxRequests" allows the maximum number
1251 of multiplexed sessions to be configured at run time. This
1252 value is not set by the NSIS installer. The default value is
1255 * New registry value "MaxVCPerServer" allows the maxmimum number
1256 of VCs per server to be configured at run time. This value is
1257 not set by the NSIS installer. The default value is 100.
1259 * New registry value "AllSubmount" allows the "all" submount to
1260 be disabled by setting its value to 0x00.
1262 * Allow cells names to be valid mount points
1263 \\<netbiosName>\<cellname>
1265 * Store the active state of drive mappings in order for afscreds.exe
1266 to restore them upon startup
1268 * Add exception handling to generate a Stack Trace to the afsd_init.log
1269 file if one happens to occur.
1271 * Add lots of logging to help detect the cause of invalid SMB packets
1273 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1274 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1275 renewal of expiring tokens as long as afscreds.exe is running.
1277 * New afscreds.exe command line options:
1279 -M = renew drive maps
1280 -N = ip address change detection
1283 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1284 determines whether or not MIT Kerberos for Windows should be used
1285 to obtain tokens via Kerberos 5 tickets.
1287 * New registry value "AfscredsShortcutParams" in
1288 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1289 determines the command line parameters to be specified when "fixing"
1290 the AFS Shortcut in the user's startup folder.
1292 * The "ShowTrayIcon" registry value has been moved from
1293 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1294 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1296 * The <cell name> registry values used to store the token expiration
1297 reminders have been moved from
1298 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1299 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1301 * Obtain the Logon User Name from the Explorer key when available
1303 * new text document doc\txt\winnotes\registry.txt lists all registry
1304 values used by OpenAFS (excluding the AFS Server)
1306 * BUG: rx_securityClass objects were not properly reference
1307 counted and were never freed.
1309 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1310 would be generated. The existence of a server does not imply
1311 that it is not down. If all of the servers for a cell are down
1312 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1315 * BUG: the directory name lookup cache failed to free the entries
1316 in the cache when the name cache entries cycled. The entries
1317 in the cache would become dereferenced without being freed.
1319 * BUG: fs setserverprefs could be executed without Administrator
1322 * BUG: the number of allocated NCB objects (100) exceeded the number
1323 which could actually be waited upon by the kernel (64). Any objects
1324 which were utilized above the limit could never have event completions
1327 * BUG: smb_username_t objects were not being reference counted and
1328 were not properly freed.
1330 * BUG: smb_tid_t objects could under unusual circumstances be freed
1331 before they were no longer referenced.
1333 * BUG: smb_fid_t object pointer were frequently used even when
1334 their value could be NULL. They were not properly released and
1335 therefore they were never freed.
1337 * BUG: smb_packet_t data structures were not completely initialized
1340 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1341 Denied" because that causes the Explorer Shell to try again until
1342 access is obtained. Instead return "Remote Resources" which allows
1343 the shell to move on and treat the error as transient.
1345 * BUG: when initializing the NCBreturns structure, separate Event objects
1346 were created for each NCB although a single Event object was supposed
1347 to be shared by all.
1349 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1352 * BUG: smb_tran2Packet_t objects were not being properly referenced
1355 * BUG: directory path creation did not handle the case of multiple
1356 directories requiring creation in one attempt
1358 * BUG: SMB requests which required an Extended Response were ignored.
1359 This prevented some files from being written to AFS volumes.
1361 * BUG: character strings were being freed even after they were
1362 inserted into in use data structures
1364 * BUG: inconsistent usernames were used when High Security mode was
1365 enabled. (there is still much to do in this area)
1367 * BUG: pioctl() calls which require out of band RPC operations were
1368 susceptible to race conditions when performed by multiple processes
1370 * BUG: memory allocation and deallocation crossed instances of the
1371 C Runtime Library producing memory leakage and corruption in
1372 afscreds and the client configurator.
