2 * Added a new registry key, "LogoffPreserveTokens" (see registry.txt),
3 that can be used to force the preservation of user tokens upon logout.
5 * Update the NSIS install scripts to use NSIS 2.07. This release adds
6 recommended installation categories: AFS Client, AFS Administrator,
7 AFS Server, AFS Development Kit. Each category includes a different
8 default subset of the OpenAFS components.
10 The OpenAFS logo is now associated with the NSIS uninstall entry
11 in the Add/Remove Programs control panel.
13 * The user name associated with AFS tokens when obtained with
14 integrated login, the afs systray tool, or aklog will always
15 include the full Kerberos 5 user principal name regardless of
16 whether or not the cell is local to the realm.
18 * Eric William's IFS redirector has been checked onto the CVS head.
19 This code is experimental at the current time and is not being
20 incorporated into the 1-4 branch releases. Instructions for
21 building from sources are found in the top-level README-NT file.
23 * Modify integrated login so that it does not enter an infinite
24 loop if the service is not set to auto start.
26 * Added asetkey.exe used to set a Kerberos 5 key for use by the
29 * Added uninstall.exe to Wix installation
31 * More modifications to algorithms used to wake sleeping threads.
35 * Changes to the algorithms used to wake threads when they are
36 put to sleep because of conflicts over buffer operations.
39 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
40 the process of producing AFS tokens. The tokens are stored within
41 the AFS Client Service but the Kerberos 5 tickets have been discarded.
42 New functionality has been added to temporarily copy the tickets to
43 a file ccache during the short window between the NPLogonNotify and
44 WinLogon Logon Event. The Logon Event handler starts a process as
45 user, afscpcc.exe, that copies the tickets into the default ccache.
46 The file ccache is then destroyed by the event handler.
48 * During synchronization operations on stat cache entries, if threads
49 are forced to sleep it was possible that the threads would not be
50 woken under heavy load.
52 * Enforce the delete on close flag specified by the NTCreateX()
55 * A race condition in the rx library was fixed that resulted in
56 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
57 was cleared when threads were still waiting to use the
58 connection. Also, fixed a potential case in which the
59 connection could be destroyed while threads were waiting to use it.
61 * The DNLC freelist has been seen to become corrupted with still
62 active entries being stored on the freelist. Changes were made
63 to perform a better job of cleaning entries before placing them
64 onto the freelist; marking them with the correct magic value when
65 purging the list; and allowing the list to be purged on startup
66 if the cache validation fails.
68 * Windows Crash Reporting does not get triggered for afsd_service.exe
69 because it provides its own top level exception handler. This patch
70 places an explicit call to ReportCrash() on platforms which support
73 If you configure Crash Reporting via AD Policy to capture crash
74 reports within the domain, then you will receive this output.
76 * Generate MiniDumps independent of the Windows Crash Reporting.
78 (a) If an exception occurs,a minidump will be generated at the path
79 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
80 can be set to any other type via use of the
83 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
85 (b) MiniDumps can be generated at any time using the "fs minidump"
86 command. This allows you to generate a minidump without
87 stopping the process or even requiring the use of a debugger
90 * an RX connection which reports bad ticket now treats it the same way
91 the expired ticket is treated. The ticket is removed from the
92 connection and a new anonymous connection is established.
94 * fs memdump now requires that the caller be in the AFS Client Admins
97 * additional debugging information is provided in cm_Analyze when the
98 error code is ignored.
100 * Fix a regression introduced into the pioctl() client code which
101 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
102 MIT KFW is not installed. (1.3.82a)
104 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
107 * Fix a race condition in cm_EndCallbackGrantingCall() that
108 could leave 'nrevp' pointing to freed memory. In the process,
109 optimize the processing to ensure that the applications monitoring
110 the status of the stat cache entry are only notified at most
113 * Conditionalize access to the Explorer Shell AFS->Mount Point
114 ->Remove menu item. Disable the item if the selected item(s)
115 are not mount points.
117 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
118 Local Storage. This eliminates thread contention on the
119 global RX free packet queue. This should improve performance
120 on multi-CPU systems.
122 * Fix the IP address filtering code to properly load/unload
123 the IPHelper DLL so that Windows XP/2003 and beyond systems
124 do not have to manually probe the registry.
126 * CleanupACLEnt() was not being called consistently with
127 the cm_scache_t object referred to by the back pointer
128 mutex locked. This could in very rare conditions lead to
129 an invalid memory access.
131 * Added a script command to the msi installer "afs_replace"
132 which can be used to replace one version of OpenAFS with
133 another without requiring an uninstall and reinstall if
134 the installed msi is no longer in its original location.
136 * Apparently the problem with multi-domain forests with cross-
137 realm trusts to non-Windows realms was not entirely solved.
138 The authentication to the AFS SMB service failed because
139 the wrong name was being used. Using ASU as an example,
140 the authentication was being performed with the name
141 "QAAD\user" (an account in the forest root) and not
142 "user@ASU.EDU (the MIT Kerberos principal used to login with)
144 The solution was to add an additional dependency on KFW
145 in order or to be able to easily obtain the client principal
146 name stored in the MSLSA ccache TGT. This information is
147 used in two locations:
149 - the pioctl() function
151 - a new WinLogon Event Handler for the "logon" event.
153 The pioctl function will now be able to use the correct
154 name when calling WNetAddConnection2() and the "logon"
155 event handler will now be able to call WNetAddConnection2().
156 The hope is that the "logon" event handler will be called
157 before the profile is loaded but I have not guarrantee
161 * Fixed a locking error in cm_TryBulkStat() which had the
162 potential of deadlocking the system for the length of time
163 it takes to perform a bulk status fetch operation.
165 * Replaced time conversion code (UnixTime <-> FILETIME) to
166 be completely arithmetic instead of relying on a bizarre
167 algorithm involving a variety of C RTL time functions.
168 This has the side effect that UnixTime and FILETIME which
169 are both stored in UTC are interpretted as UTC throughout
170 the year. Windows will apply the same localization to AFS
171 as it does to NTFS. Applications which rely on the ability
172 to sync files between the two file systems will no longer
173 see the timestamps of files in AFS change an hour relative
174 to the files stored in NTFS or Windows based backup devices.
176 * Fixed a invalid memory access under a bizarre circumstance.
177 Windows will allow a physical mass media device to be
178 installed via Plug N Play to the system and will assign it
179 the lowest available drive letter. This is true even if the
180 drive letter is currently assigned in the user session to
181 a network device via NET USE (or its equivalent.) When this
182 happens, queries sent to the CIFS server will contain invalid
183 data. This invalid data was not being caught by the AFS
184 Client Service and was resulting in a crash when Freelance
187 * Fixed a reference count error when registering callbacks
188 on a stat cache object if the callback was already registered
190 * Add a case to cm_Analyze() in order to handle the case where
191 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
192 the server list for the volume is empty. In this case, force
193 an update of the volume info and retry.
195 * Insert a missing cm_EndCallbackGrantingCall() which could
196 result in threads waiting for a callback to complete to never
199 * In the persistent cache, there is a maximum number of volume
200 entries. Allow volume entries to be reused if the maximum
201 number have been allocated and their reference count is zero.
203 * If we already have a dead virtual connection object, don't
204 ignore the fact that additional dead vc objects must be taken
207 * Removed a deadlock condition introduced in the summer of 2004.
208 Do not hold mx locks around calls to RX functions including
209 rx_NewCall(). That is what reference counts on the rx_connection
212 * Fixed an initialization error in afslogon.dll which could
213 result in random behavior including a failure to terminate
214 the NPLogon function. (1.3.80b)
216 * Fixed an error preventing the use of SMB authentication
217 on Windows 2000. (1.3.80a)
220 * Updated CellServDB to Public CellServDB 16 Mar 2005
222 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
223 misinterpretted as "csail.mit.edu" when the resolver
224 is configured to append ".mit.edu" to failed DNS queries.
226 * Fixed another case in which the client would replace connections
227 to the host when it was not necessary. In this case the
228 situation would occur if cryptall was on and the connections
229 were unauthenticated due to lack of an appropriate token.
231 * OpenAFS for Windows has failed to work at sites which are
232 utilizing a cross-realm trust between an MIT/Heimdal realm
233 and a multi-domain Windows forest when the workstation being
234 accessed is not located in the root domain. This is caused
235 by a bug in the workstation which was triggered after the
236 introduction of Windows 2003 Server. When the bug is triggered,
237 the workstation attempts to authenticate users to afsd_service.exe
238 by contacting the Domain Controller instead of using the
239 LSA loopback authentication mechanism.
241 One of the reasons this bug occurs is because the workstation
242 does not have a reliable way of knowing that the service whose
243 netbios name is "AFS" is located on the workstation. This will
244 be fixed starting in Longhorn Beta 1 by Microsoft. The
245 "BackConnectionHostNames" registry value will be used to
246 indicate that the authentications to that service name should
247 be performed using the loopback authentication mechanism.
249 In the meantime, when Logon Caching is enabled, we can force
250 afsd_service.exe to authenticate using the logon cache before
251 contacting the Domain Controller. This will work with both
252 password and smart card based logons.
254 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
255 flag should not be cleared if a volume's server reference is
256 marked as "offline". In the case where all of the volume's
257 servers are either "down" or the volumes are "offline", we want
258 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
259 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
260 should never occur in practice.
262 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
263 5 seconds, clear the server down and volume busy flags, and
264 then force an update from the VLDB. This allows the client to
265 update the location of a volume if the reason for it being
266 marked offline is because it is being moved. Calls to
267 cm_ConnByMServers() will be retried either until success or
268 the RDRtimeout period is reached.
270 * Correct the Power Management code behavior in response to
271 Standby, Suspend, and Shutdown events. Instead of flushing the
272 buffers associated with the mounted SMB submounts, simply write
273 all buffers which are marked dirty.
275 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
276 provides a list of cells other than the default cell for which
277 tokens should be obtained using the default Kerberos principal.
278 This functionality is logon domain specific and is only available
279 when using KFW for authentication.
281 * Fixed FindNext Invalid Handle error caused by over agressive
282 attempts at garbage collecting dirSearch entries when the
283 dirSearch ID wraps from the maximum value to 1.
285 * Add support for registry defined server preferences for VLDB and
286 File servers. See registry.txt for details.
288 * Increased default cache size to 96MB and default number of cache
291 * Fixed refCount leaks related to directory lookups and pioctl calls.
293 * Callbacks revoked during a race condition with an attempt to
294 obtain the same callback no longer result in an inaccessible
297 * New command line tool:
299 afsdacl : Set or reset the DACL to allow starting or stopping
300 the afsd service by any ordinary user.
302 Usage : afsdacl [-set | -reset] [-show]
304 -reset : Reset the DACL
305 -show : Show current DACL (SDSF)
307 * IP addresses are no longer queried once at startup. Instead IP
308 addresses are obtained as needed. Loopback adapter addresses are
309 no longer published to the server.
311 * Pay attention to the MIT KFW registry configuration for automatic
312 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
314 * Fix (once again) case-sensitive comparisons which was apparently
317 * Activate support for vos listvol -format
319 * Population of the "AFS Client Admins" group failed on non-English
320 versions of Windows because the name of the "Administrators" group
321 is localized. Now we lookup the name of the group by using the
322 Administrators Group Alias Relative ID.
324 * Multiple cell token acquisition within afscreds.exe was broken in the
325 case of Kerberos 5 cross realm authentication. Instead of contacting
326 the KDC associated with the cell's realm, afscreds would obtain a
327 token from the KDC of the user's realm. This would result in
328 "invalid kvno errors" while authenticating to the AFS servers.
329 Unauthenticated access would work. The symptoms would vary based upon
330 whether or not the VLDB servers had been contacted using unauthenticated
331 connections prior to the user obtaining tokens.
333 * The list of ACL entries was becoming corrupted. It appears as if
334 an ACL when it expires was not being appropriately cleaned up. In
335 fact, it was left in the list of ACLs associated with the scache
338 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
339 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
340 and "amd64_win64" for amd 64-bit processors.
342 * When executing executables, Windows provides a mechanisms by which
343 the normal search for DLLs can be bypassed. If a file foo.exe is
344 being executed and there exists a file or directory "foo.exe.local"
345 (the contents are ignored if a file), then Windows will search for
346 DLLs first in the "foo.exe.local" directory and second in the
347 directory in which the "foo.exe" file is located.
349 Previous releases of OAFW would improperly return
350 STATUS_NOT_A_DIRECTORY instead of the expected
351 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
352 to terminate the search for the DLL causing the execution of the
355 * Rework the reference counting of smb_vc_t objects. The references
356 stored in the waiting locks were not counted. This could result in
357 an assertion if the reference count drops to zero.
359 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
360 when running in freelance mode.
362 * Added support for persistent caching of file contents, stat entries,
363 volume data, cell data, and name lookup data. When the registry
364 value, "NonPersistentCaching", is not defined or set to 0 the file
365 specified by "CachePath" becomes a persistent cache file. The
366 size of the cache file is computed at run time. It has a maximum
367 size of approximately 1.2GB. The contents of the file will be
368 validated according to the rules specified by the "ValidateCache"
371 * Added support for UUIDs. UUIDs are kept for as long as the
372 cache file is intact.
374 * Added cmdebug.exe and support cache manager debugging callback
375 interfaces in afsd_service.exe.
377 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
378 [-addrs] [-cache] [-help]
379 Where: -long print all info
380 -addrs print only host interfaces
381 -cache print only cache configuration
383 * Symlinks to \\AFS\[all\]... will now be treated the same as
384 symlinks to /afs/.... However, please use /afs/... as otherwise
385 the symlinks won't work on Unix.
387 * Correct a problem with local CellID allocation for cells whose
388 server list is obtained via DNS instead of a CellServDB file. If
389 the DNS information expires the CellID assigned to the entry will
390 be changed. This causes all of the cm_scache_t objects which refer
391 to the old cellID number to become useless. Attempts to access
392 files or directories with cm_scache_t objects using the old cellID
393 will fail since the server list cannot be obtained.
395 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
396 be triggered if the volume referenced by the cm_scache_t object is
399 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
400 in addition to SERVICE_ACCEPT_STOP.
402 * Move RPC shutdown until after the SMB and RX shutdown procedures
403 complete. Block until RPC shutdown is complete.
405 * Modify afslogon.dll (integrated logon) to wait for service if its
406 state is START_PENDING. If the timeout period occurs, reset to
407 the retry interval and not the sleep interval.
409 * When renewing the server list for a cell obtained via DNS AFSDB
410 records, the cm_cell_t entry must be removed from the list of all
411 cells. Otherwise, the list of cells will be corrupted.
413 * In the dcache and scache modules, use the cm_scache_t dataVersion
414 instead of the cm_fakeDirVersion.
416 * Synchronize fs.c with the unix version.
418 * The variable used to determine whether a file or virtual memory
419 mapped cache is used was not properly initialized to a default
420 value. If the registry setting "NonPersistentCaching" was not
421 set, the choice would be random. Properly initialized to be
424 * The memory mapped view was never unmapped before closing the file
425 at service shutdown. This is now properly cleaned up.
427 * Default location of Cache file is now %TEMP%\AFSCache
431 * A bug affecting new installations of 1.3.75/76 would result in
432 the creating of incorrect mountpoints in the freelance root.afs
433 volume for the default cell.
435 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
436 of "root.cell", you have been affected by the bug. To correct the
437 problem, execute the following commands:
439 fs rmmount \\afs\all\<cellname>
440 fs rmmount \\afs\all\.<cellname>
442 fs mkmount \\afs\all\<cellname> root.cell <cellname>
443 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
447 * A bug has been fixed in the auto-generation of Freelance root.afs
448 symlinks which produced random entries in the \\AFS\all directory.
450 * Support has been added for multi-homed servers
453 * Added a new registry value, "StoreAnsiFilenames", which can be used
454 to force the use of ANSI character sets instead of OEM Code Pages.
455 This feature is useful when users require the ability to create
456 filenames with 8-bit characters and need to access the files from
457 both Latin-1 based Unix systems as well as from Windows.
459 Activation of this feature will prevent access to files stored with
460 8-bit OEM characters.
462 * Shutdown all SMB threads in a synchronized manner when stopping the
465 * There is currently a maximum cache size of 1.3GB. The limit is imposed
466 by the largest contiguous block of unused memory within the 2GB process
467 space which can be assigned to the memory mapped file. Unfortunately,
468 when the executable digital signature verification code is activated
469 Windows sees fit to further segment the process memory which in turn
470 reduces the size of the maximum cache file to less then 800MB. If
471 larger cache sizes are desired, a new registry value should be set:
473 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
475 Setting this value will disable the runtime verification of digital
476 signatures on afsd_service.exe and the afs dlls which it loads. It
477 will not disable the the version number check on those same files.
478 The signature verification is not a security messure and is only meant
479 to enhance the ability to afsd_service.exe to detect potential
480 destablizing mixtures of DLLs from incompatible distributions.
482 Added code to auto-disable the signature verification check if
483 the desired cache size is greater then 700MB.
485 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
486 used to verify the validity of the afsd_service.exe binary
487 as well as each of the AFS DLLs loaded by the service. Not only
488 must the digital signature be valid but the signatures of the
489 DLL must be signed by the same entity as the service.
491 * Implement new functions: cm_freelanceMountPointExists and
492 cm_freelanceSymlinkExists. Use them along with other validity
493 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
494 ensure that name collisions do not occur and that empty strings
495 are not valid file names.
497 A symlink may not have a name which would resolve to a valid
498 cell name. Doing so would prevent access to the cell.
500 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
501 re-initialization code. The reference counts of the fake root.afs
502 volume scache object(s) would become invalid when the mount point
503 or symlink lists were altered.
505 * Add registry entries to provide mappings from the afsdsbmt.ini
506 to the new locations for applications which count on the use
507 of the old Profile file APIs. These apps are likely to fail
508 if the user does not have administrator privileges and the
509 registry is locked down.
511 * The afs_config.exe submounts dialog had two errors.
512 First, attempts to remove entries failed because the registry
513 key was being opened without KEY_WRITE privileges.
514 Second, when editing a submount entry, changing the name
515 would add a new key and leave the original one in place.
516 Now the original submount will be removed if its name is
519 * In recent months there have been several incidents in which
520 users have experienced problems starting or accessing
521 afsd_service.exe and after significant effort has been spent
522 it has turned out that they have two versions of AFS on the
523 machine or an inconsistent set of DLLs.
525 Code has now been added to afsd_service.exe which will walk
526 the list of modules loaded by afsd_service.exe and validate
527 that the version of the AFS DLLs matches the version of the
528 afsd_service.exe executable. If they do not match the service
531 * When Freelance mode is enabled and there is no registry
532 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
533 will attempt to import the afs_freelance.ini file contents.
534 If the file does not exist, it was creating a dummy file
535 with a r/o and r/w entry for the default cell and then
536 importing those values.
538 This process has been changed. The temporary file is no
539 longer created. Also, both the OpenAFS Client install
540 directory as well as %WINDIR% are checked for previous
541 afs_freelance.ini files.
543 * Added support for VL_GetEntryByNameN(). Still need to add
544 support for VL_GetEntryByNameU() for multi-homed support.
546 * Fix a deadlock situation in afscreds.exe when canceling an
547 auto-generated Obtain Tokens dialog
550 * Fix the locking of objects during Directory Searches in the
551 SMB/CIFS server. The failure to properly lock the reference
552 counts was resulting in the premature freeing of smb_dirSearch_t
553 objects while they were still in use by the SMB/CIFS client.
554 This does not solve the "Invalid Handle" problem.
556 * Fix Find Cell By Name pioctl call to return a valid cell
557 name for the Freelance fake root.afs volume.
558 "Freelance.Local.Root".
560 * Fix the Explorer Shell Extension Symlinks->Add operation.
561 The dialog template was missing and the link destination
562 string was too short.
564 * Add support for symlinks to Freelance root.afs volume
565 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
566 <number> = "<linkname>:<relative-path>."
567 Use symlink.exe to create, list, or remove
569 * Remove the fallback to the use of KFW's KRB4 library when obtaining
570 tokens. We never obtain KRB4 tickets.
572 * Fix AFS Client Configuration Control Panel to support new SysName
575 * Fix a bug in afsd_service.exe which could result in the SysName
576 not being read from the registry.
579 * Add code to block the issuance of AFS tokens by aklog.exe or
580 afscreds.exe when the Kerberos 5 principal name contains a dot.
582 * Modify the IsAdmin() function to always treat the local SYSTEM
583 account as an AFS client administrator. Affects fs.exe and
586 * Modify the internal handling of Quota Exceeded errors
588 * Upgrade all reference count fields in the Windows cache manager
589 and the osi library to use unsigned long instead of signed short.
590 A similar fix has been applied to the afs rpc (rx) library.
592 * fix the Windows cache manager to prevent it from replacing the
593 rx_connection object associated with the cm_conn_t object on each
594 and every operation if "fs crypt" was set. This explains the
595 dramatic performance difference when crypt is used vs clear.
596 The problem: 'cryptall', a boolean flag indicating whether or not
597 "fs crypt" is set, was being compared to the rx_connection
598 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
599 1 != 2 and therefore the rx_connection was always destroyed
600 and replaced on each and every operation.
602 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
603 It is not safe for the cm_conn_t object to not be locked because
604 rx_DestroyConnection might be called from another thread if:
605 - the user's tokens have changed or expired
606 - the crypt mode has changed
608 This fix appears to have also taken care of the problems associated
609 with Overlapped Writes resulting in Delayed Write errors.
611 * fix NSIS installer's AdminGroup.exe to properly create and
612 remove groups when given -create or -remove. The string comparison
615 * fs sysname now accepts a list of sysname values
617 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
618 DWORD which when set to a non-zero value will cause error message
619 text to be output to stderr from the pioctl() routine. Useful in
620 debugging failures of fs.exe, tokens.exe, etc.
622 * added a test to the power management code to only perform a
623 flush operation if there is at least one network adapter which
624 is not a loopback adapter.
626 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
627 "EnableKFW". This value will not be read if the key
628 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
629 value under that key does not.
631 * provide mechanisms to force the use of krb524d for Kerberos 5
632 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
633 there is a new registry value "Use524" and for aklog.exe a new
634 command line parameter "-m".
636 * Fix the pattern matching algorithm to properly match patterns
639 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
640 which is used by both the original function and the new
641 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
642 creation of HardLinks in addition to Renaming. smb_Link()
643 is a new function which creates HardLinks via cm_Link().
644 cm_Link() is a new vnodeops function which creates links
647 smb_ReceiveNTRename() does not support the File Copy and
648 Move Cluster Information operations described in its interface.
649 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
651 * When opening files via symlinks, we should follow the symlinks
652 until we reach the actual file stat cache entry. The stat cache
653 entry of the file should then be stored in the FID instead of
654 stat scache entry of the symlink.
656 * return bad operation errors for all unimplemented functions
657 even if we do not know the functions exist.
659 * Log bad packets and unknown operation packets to the trace log
661 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
664 * Update list of known CIFS operations to include all those listed
665 in CIFS-TR-1p00_FINAL.pdf.
667 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
668 to support the REG_EXPAND_SZ type.
671 * A new Windows authorization group "AFS Client Admins" is now
672 created and populated with the members of the "Administrators"
673 group. The group is used to determine which accounts on the
674 machine may be used to modify the AFS Client Configuration via
675 the UI and command line tools. afs_config.exe, fs.exe,
677 * Modify the WinLogon Logoff Event Handler to query NT4 domain
678 controllers for the remote profile path if Active Directory
679 services are not available.
681 * Fix aklog.exe to not add the AFS ID to the username
683 * PTS registration of new users to foreign cells has been added to
686 * The cm_Daemon thread is used to perform checks for
687 down servers, up servers, volumes, callback expirations,
688 lock maintenance and token expiration. Due to a gaff in
689 larger integer division the thread never performed any
690 work. Instead the current time computation would always
691 be less then the trigger times. This had an adverse affect
692 on the client's ability to maintain communication with servers,
693 keep volumes up to date, and flush user tokens and acls
694 when they have expired. This was broken when the 1.3 branch
695 was modified to support VC7 which no longer included
698 * An initialization problem with the Freelance code was
699 detected while fixing the callbackRequest. The cm_rootSCachep
700 object is obtained during afsd_InitDaemons() but the callback
701 information is incomplete. The callback information will not
702 be obtained until cm_MergeStatus is called from within
703 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
704 test for the conditions under which the callback information
707 * Reports have been filed indicating that callbacks were
708 being lost. An examination of the code indicated that the
709 cm_server_t objects were not being properly reference
710 counted by the cm_scache_t and cm_callbackRequest_t objects.
711 In particular, the cm_server_t objects may have been freed
712 from beneath the cm_conn_t objects.
714 All of the reference counting is now done via the functions:
719 this improves the ability to track the referrals.
721 Each cm_BeginCallbackGranting Call now allocates a reference
722 to the cm_server_t. The cm_EndCallbackGrantingCall either
723 frees the reference or transfers it to the cm_scache_t
724 cbServerp field. These are then appropriately tracked
725 through the cm_Analyze call.
727 * Ensure that the dnlc hash table is the same size as the
728 dir name hash table (as per original author's note).
729 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
730 for compatibility with 64-bit systems.
732 * fix smb_ApplyV3DirListPatches to properly apply the hidden
733 attribute to dotfiles when the infoLevel < 0x101 and
734 cm_SyncOp has failed.
736 * Fix the Freelance registry initialization code. There
737 was a possibility that some systems could end up with
738 garbage in the registry during a clean install.
741 * file and directory names beginning with "." will now be given the
742 hidden attribute when the volume access is anonymous. this matches
743 the behavior when the volume access is via an authenticated user.
745 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
746 key. When a change occurs mark the root.afs data as invalid and
747 for it to be reloaded on the next access. This allows administrators
748 to modify the mount point list without restarting the service.
750 The freelance client used to provide a fake modification time for
751 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
752 Added code to extract the last modification time of the Freelance
753 registry key and use that instead. The time now represents the
754 most recent mount point change.
756 * PTS registration of new users to foreign cells has been added to
759 * Additional Cache Control and Credential Manager options have been
760 added to the WiX installer. See deployment guide for details.
762 * The CachePath setting is now optionally a REG_EXPAND_SZ type
764 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
767 * The loopback installation code may have had a problem updating the
768 %ETC%\HOSTS file which could have resulted in a premature failure.
769 Work around code has been added for the case where the file cannot
772 * The default max chunksize was increased from 15 (32K) to 17 (128K)
773 because Windows sends 64K blocks when using overlapped writes.
775 * The default number of server threads was increased from 4 to 25 to
776 better handle overlapped writes.
778 * The "AfscredsShortcutParams" registry value was not being properly
779 loaded by afscreds.exe. Therefore, the default value was always being
780 used instead of the value set by the installer.
782 * Windows XP provides downgrade attack detection to prevent an attacker
783 from being able to force the use of NTLM simply by disrupting
784 communication with the KDC. This attack cannot exist between the
785 Windows CIFS client and the AFS Client Service. Therefore, when a
786 downgrade has been detected the afs pioctl library will force the
787 establishment of a new CIFS connection using NTLM.
789 * A locking error was discovered surrounding all references to volume
790 server lists within the cm_cell.c source file.
792 * The logged into Windows username was incorrect on Terminal Server
795 * A new registry value "NonPersistentCaching" was added to the service
796 parameters key. When set to a non-zero value, the afs cache is stored
797 in the Windows paging file. There are two limitations to choosing
799 1. when persistent caching is implemented it won't work with
800 this flag set since there will be nothing to persist.
801 2. with this flag set the initial paging allocation cannot be
802 changed while the service is running
804 * An initialization bug was discovered in aklog.exe which affected users
805 who have a domain name for their afs servers which could not be mapped
809 * afs_config.exe now validates cell names against DNS in addition
810 to the CellServDB file.
812 * In order to allow the freelance client to connect to a volume with ID
813 equal to 1 on the default cell we changed the fake root.afs volume ID
814 once again. This time we choose 0xFFFFFFFF. In addition, we change
815 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
816 It will now be impossible for a volume ID to match that of another
817 cell unless the client is connected to 0xFFFFFFFD cells. That should
818 be enough room for growth.
820 * Fix "fs mkmount" command to work with UNC paths and when
821 started from non-AFS drives. It is now possible to create a mount
822 point in the freelance fake root.afs volume with the command
824 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
828 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
829 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
831 * The algorithm used to re-attempt access to the servers associated with
832 a volume has been altered to properly address the case in which all
833 servers have been marked down. The previous algorithm did not reset
834 the server's down flags so the servers were never actually retried.
835 This caused a problem with active volumes if the network connectivity
836 was lost as could be the case with a network cable removal, wireless
837 drop, or laptop hibernation. With the fix volume access is restored
838 almost instantenously when network connectivity becomes available.
840 * Support for SMB/CIFS browsing has been added to the AFS Client Service
841 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
842 listing of AFS submounts and freelance mount points. Support for
843 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
844 significantly enhances the behavior of AFS volumes within the Explorer
845 Shell. For instance, "AFS" now shows up as server in the Explorer
846 with each submount or freelance mount point visible as a share.
847 The right click menu in each folder now works with full functionality
848 on a consistent basis.
850 * The network provider can be configured to have different behavior
851 depending on the domain that the user logs into. These settings are
852 only relevant when using integrated login. A domain refers to an
853 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
854 local machine (i.e. local account logins). The domain name that is
855 used for selecting the domain would be the domain that is passed into
856 the NPLogonNotify function of the network provider. (see registry.txt
859 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
860 "Authentication Cell" which may be used to specify a default
861 authentication cell for afscreds.exe which is different from
862 the default cell for the AFS Client Service daemon.
864 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
865 afslogon.dll moved to %WINDIR%\System32\.
866 New registry entries added to register the dll for Winlogon events.
868 The logoff event will now force a call to ktc_ForgetAllTokens()
869 using the context of the user being logged off as long as the
870 user's profile is not loaded from within AFS. If the profile
871 was loaded from AFS we can't release the tokens since the Logoff
872 event is triggered prior to the profile being written back to
873 the its source location. This is now performed in an XP SP2
876 * Windows XP SP2 Internet Connection Firewall interoperability
879 * The %WINDIR%\afsdsbmt.ini contains four sections:
880 Submounts, Drive Mappings, Active Maps and CSC Policies.
881 The Submounts and CSC policies are now stored in the registry under
882 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
883 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
884 The Drive Mappings and Active Maps are stored in the registry under
885 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
886 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
888 There is no automatic migration of this data as it would be impossible
889 to consistently migrate data to user profiles which may not be active
890 when the machine is updated.
892 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
893 fake root.afs volume. For the same reasons as for the cellservdb file,
894 this information should not be in %WINDIR%. This information is now
895 kept under the registry key
896 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
898 The data from the afs_freelance.ini file will be automatically
899 migrated to the registry on first execution of afsd_service.exe
901 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
902 troublesome for several reasons. One, it is confusing for those who
903 expect the file to be named "CellServDB" instead of "afsdcell.ini".
904 Two, this file is not a Windows Profile formatted file. Three,
905 applications should not be reading or writing to %WINDIR%. It causes
906 problems for Windows Terminal Server.
908 The new location of CellServDB will be the OpenAFS Client install
909 directory which is by default C:\Program Files\OpenAFS\Client and can
910 be determined by querying the registry for
911 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
913 The existing afsdcell.ini will be migrated by the NSIS installer.
914 The Wix installer must still be updated to do the same.
916 * Change NSIS installer to use DNS by default; to remove Integrated Logon
917 High Security mode; and to add Terminal Services compatibility registry
918 entries to allow the OpenAFS tools to find the afsdcell.ini and other
919 configuration files in %WINDIR%.
921 * Add support for authenticated SMB connections. This will remove
922 the need for high security mode in most situations. Both NTLM
923 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
924 only NTLM can be used even though Kerberos is now supported. The
925 reason is that it is not possible to construct a service principal
926 which is unique to each individual machine.
928 SMB Extended Auth does not work on XP SP2 unless one of two registry
929 modifications are made:
931 (1) To disable the check for matching host names on loopback connections
932 set this key. This does not require a reboot:
934 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
935 "DisableLoopbackCheck"=dword:00000001
937 (2) To add the AFS SMB/CIFS service name to an approved list. This
938 does require a reboot:
940 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
941 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
943 afsd_service.exe will automatically add the current Netbios Name
944 to the BackConnectionHostNames list and then temporarily disable
945 the loopback check for one cycle of startup/shutdown of the service.
946 We assume most folks do not start/stop without a reboot so this
947 will be adequate in most cases.
949 * Fix security hole in afslogon.dll which allowed passwords to be
950 sent in clear text to the KDC in a misformed principal name.
952 * Fix cm_GetCell() to properly handle expired dns entries
955 * If Freelance mode is active and the afs_freelance.ini
956 file does not exist, do not create an empty file.
957 Instead create a file containing ro and rw mountpoints
958 to the default cell using the standard conventions.
960 * Modify the Freelance support to handle the ability
961 to create rw mount points in the fake root.afs volume.
963 * Changed the RPC mechanism used for token setting from
964 named pipes to local. Use of named pipes can be restored
965 by setting the environment variable AFS_RPC_PROTSEQ to
968 Named pipes were required when a Windows 9x system was
969 using a NT system in gateway mode which is incompatible
970 with our use of local loopback adapters.
972 * In afscreds.exe, if a username of the form user@REALM is
973 specified and no password is specified, do not perform a
974 kinit operation. Only perform the aklog functionality.
976 * Add a new registry value which allows the number of processors
977 on which afsd_service.exe executes to be restricted. Valid
978 values are 1..numOfProcessors
980 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
984 * A second MSI based installer option is now available.
986 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
987 request tickets for user/instance@REALM instead of just user@REALM
989 * Modify the Power Management Notify routine to wait for the Hard Dead
990 timeout period instead of a fixed 19 seconds. With the longer timeout
991 periods Hibernation and Standby could never succeed when network
992 connectivity is not available.
994 * The following fs.exe commands are now restricted to Administrator:
995 - checkservers with a non-zero timer value
998 - sysname with a new sysname list
1007 setting the default sysname for a machine should be done via the
1008 registry and not via "fs sysname".
1010 * NSIS installer adds options to install Debugging Symbols
1011 and the Microsoft Loopback Adapter; the user is now also
1012 given the ability to select the afscreds.exe startup options.
1014 * Build system modified to generate symbols for FREE (aka RELEASE)
1015 builds as well as CHECKED (aka DEBUG) builds
1017 * Sites which have a volume ID of 0x20000001 assigned to their
1018 root.cell volumes have been experiencing problems with accessing
1019 the root.cell volume of their cell when Freelance mode has been
1020 active. This was because 0x20000001 was assigned to the fake
1021 root.afs volume created by freelance. The fake volume id is
1022 now set to 0x00000001 to prevent conflicts.
1024 * The timeout logic in the AFS Client Service has been wrong
1025 for sometime. It is based on two different assumptions.
1026 First, the SMB client timeout is a fix value as was the case
1027 with OS/2 Lan Manager. This assumption is incorrect. The
1028 SMB timeout in Windows is a dynamic value computed based upon
1029 a fixed minimum timeout to which is added time based upon the
1030 size of the request and the performance characteristics of
1031 the connection. Second, it is the responsibility of the
1032 SMB Server to enforce the timeout requirements of the client.
1033 This is untrue. The SMB Server cannot be expected to know
1034 the requirements of the client. More importantly, if the
1035 SMB server uses the SMB client timeout as a value to restrict
1036 its behavior as an RX client, the performance characteristics
1037 of the local SMB session would be used to prematurely terminate
1038 WAN connections with significantly different performance
1041 The timeout logic has therefore been modified in the following
1043 . the Lan Manager Workstation (SMB) Session Timeout is used only
1044 as a basis for configuring the Connection Dead Timeout
1045 and Hard Dead Timeout values. The Connection Dead Timeout
1046 must be at least 15 seconds longer than the SMB Timeout
1047 and the Hard Dead Timeout must be at least double the
1048 Connection Dead Timeout.
1049 . New registry entries have been added to allow the Connection
1050 Dead Timeout and Hard Dead Timeout values independent of the
1051 Lan Manager Workstation Session Timeout
1052 . The test to enforce the SMB Client Timeout has been removed.
1054 One of the side-effects of removing the enforcement of the SMB
1055 Client Timeout is that regardless of whether or not the SMB client
1056 is available to receive the response (and how would the SMB server
1057 know) the RX protocol response can be used to update the AFS
1058 Client Service state for ready access by future SMB client
1061 This should be the end of the "Server paused or restarting messages"
1063 * Add support for arbitrary UNC paths to the pioctl() support.
1064 This enables the fs commands as well as the AFS Shell Extension
1065 to work correctly when UNC paths are being used.
1067 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1068 DNS if the cell configuration cannot be determined via CellServDB
1070 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1071 are ever set more than once at a time
1073 * Fix the management of lists of cm_cell_t structures when using
1074 DNS to lookup cell information. The previous code would fail to
1075 reuse the same cellID for a cell if DNS was used more than once
1076 for a given cell name. When the ttl expired, a single cm_cell_t
1077 could be inserted into the cm_allCellsp list more than once
1078 producing a loop. In addition, the vlServerp list belonging to
1079 the cell was not freed resulting in improper refCounting of the
1082 * Add DNS support to cm_IoctlNewCell() which previous only examined
1085 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1086 to properly garbage collect cm_server_t objects
1088 * Add numVCs variable to smb.c to track the number of smb_vc_t
1089 objects created and use it to initialize the vcID field which
1090 previously was set to 0 in all objects resulting in FindByID
1093 * Fixed DNS lookups to work consistently throughout the OpenAFS
1094 product instead of just from within the afsd_service.exe
1096 * Added a runtime check to ensure that AFS Client Service SMB
1097 Server is accepting connections before attempting to mount
1100 * Read IP addresses for volume servers out of the CellServDB
1101 file if gethostbyname() on the hostname fails.
1103 * Fix getcellconfig() to populate both the Hostnames as well
1104 as IP addresses when loading cell data via DNS
1106 * Increase the Connection Dead Time to 50 from 20 seconds
1107 Increase the Hard Dead Time to 120 from 40 seconds
1108 (matches the Unix values)
1110 * Fixed an assertion validating the number of allocated NCBs
1112 * Fixed the build environment to consistently build for
1113 Windows 2000 and above. (APPVER = 5.0)
1115 * Fixed rx_debug to properly validate the receipt in incoming
1116 data with select() and recvfrom(). Do not copy data out of
1117 the socket buffer unless success is indicated.
1120 * afsd_service.exe will now display a message box to the
1121 desktop when it terminates due to an IP Address Change.
1123 * installer no longer deletes AFS Server configuration data
1126 * installer generates a warning dialog if the RPC service
1127 is not properly configured
1129 * installer compressed with lzma instead of bzip2
1131 * afsd_service.exe shutdown crash solved once and for all
1133 * reference counting of smb_vc_t data structures improved
1135 * name space collision of smb_fid_t event objects corrected
1137 * the output of "fs memdump" is now written to
1138 %WINDIR%\TEMP\afsd_alloc.log
1140 * the file TaAfsApp_1033.dll is now properly installed allowing
1141 the User Manager to start
1143 * a new algorithm is used for computing filename pattern matches
1145 * afscreds.exe now accepts user names containing instance
1148 * Fix the Directory Name Lookup Cache to be case-sensitive.
1149 This is crucial in environments in which a Windows client
1150 is accessing a directory with more than one filename that
1151 differs only by case. If the directory contains "FOO"
1152 and "Foo". You want "DEL Foo" to delete the correct one.
1153 We still have a problem in that "DEL foo" will delete a
1154 random filename. This will be addressed in a future release.
1156 * Fix afscreds.exe -M option (renewMaps) to work when High
1157 Security mode is off. Also, remember to disable the ActiveMap
1158 flag in afsdsbmt.ini when a drive mapping is removed.
1160 * Updates to NSIS installer script. AFS Server configuration
1161 data will not be destroyed on un-install or re-install.
1162 Use a better compression algorithm.
1164 * afslogon.dll now uses KFW to obtain tokens when available
1166 * afslogon.dll when given an all uppercase username will
1167 attempt to authenticate with both the uppercase name
1168 and an all lowercase variation
1170 * DST modification removed. The fix appears to make things
1171 worse after a reboot of the machine.
1173 * fs.exe: added "cscpolicy" which is used to
1174 change client side caching policy for AFS shares
1176 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1177 [-documents] [-disable] [-help]
1179 * Several uninitialized variables have been initialized
1181 * It is now possible to obtain tokens using cross realm
1182 Kerberos within afscreds.exe:
1184 user: jaltman@ATHENA.MIT.EDU
1186 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1187 will will in turn be used to obtain afs@DEMENTIA.ORG.
1188 The resulting token will be stored with the display name
1189 jaltman@ATHENA.MIT.EDU@dementia.org
1191 * aklog.exe has been added to the client
1193 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1194 [[-p | -path] pathname]
1198 -d gives debugging information.
1199 krb_realm is the kerberos realm of a cell.
1200 pathname is the name of a directory to which you wish to authenticate.
1201 -noprdb means don't try to determine AFS ID.
1202 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1203 (default is Kerberos V)
1204 No commandline arguments means authenticate to the local cell.
1207 * All of the resource files have been restructured to adhere to
1208 a set of rules IBM implemented for loading string resources.
1209 These rules had either been forgotten or were not discovered
1210 by folks working on the OpenAFS sources. The end result was
1211 memory corruption. This is primary item which was preventing
1212 the AFS Server from working.
1214 * Increased the size of the maximum ticket size stored in a token
1215 from 344 bytes to 12,000. Increased the buffers used to convey
1216 messages between the pioctl() caller and the SMB Server from
1217 1000 bytes to 12,512. The code appeared to have been writing
1218 above the top of the stack by quite a few number of bytes.
1219 (The increased ticket size is necessary for the next item.)
1221 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1222 Instead the raw Kerberos 5 ticket is used in its entirety. This
1223 is extremely important as it allows us to use pure Kerberos 5 KDCs
1224 as the source of the AFS authentication. The use of up to 12,000 byte
1225 tickets will allow tickets produced by all versions of Microsoft
1226 Active Directory to be used.
1227 - create a user account.
1228 - designate it DES only
1230 - specify its UPN to be "afs@realm"
1231 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1233 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1234 is special when using long file names. (you must use "*.*" and not "*")
1235 Instead only enforce it when performing 8dot3 searches.
1237 * Fixed the DST problem with creation times being set one hour ahead
1239 * Fixed the problem when using \\afs\cell-alias. For example,
1240 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1241 for the alias name; instead simply expand the name. One of the
1242 symptoms of this problem was a loss of acquired tokens.
1244 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1245 of strings. (Only English strings provided.)
1247 * Fixed the installer to properly replace in use files.
1249 * Fixed the build system to cleanup generated component version files
1251 * The release build compiled with MSVC 6.0 compiler to avoid the
1252 afsd_service.exe shutdown crash. This does not solve the problem
1253 but simply avoids it for the time being.
1257 * fix afslogon.dll to not corrupt memory when High Security mode
1260 * fix afsd_service.exe to not attempt to restore the stack when
1261 an exception occurs. (not safe in multi-threaded programs)
1263 * fix uninstaller to properly remove the CRT and MFC DLLs
1265 * remove a Message Box from afscreds.exe when getcellconfig()
1266 fails on a kerberos realm which is not a cell
1268 The following is a list of changes to the OpenAFS for Window client
1271 * "fs setserverprefs" will leave afsd service deadlocked
1273 * "vos listaddrs" will core dump
1275 * installer sets the appropriate keys to support Integrated Logon
1277 * installer disables the "Find Lana by Name" functionality as it
1278 was causing headaches for many users
1280 * fix the intermittent crash of the power management thread when
1281 shutting down the AFS Client Service
1283 * optimizes the obtain drive mount list functionality which is
1284 executed every time the mount tab in afscreds.exe and afs_config.exe
1285 are refreshed. (this happens a lot)
1287 * fix the service shutdown logic. add the STOP_PENDING state
1288 and do not accept additional service events after we declare
1291 The following is a list of changes to the OpenAFS for Window client
1294 * flexelint was run against the source tree and hundreds (perhaps
1295 thousands) of corrections were applied to ensure prototypes
1296 were in use; types were used consistently; variables were
1297 initialized; unused variables were removed; etc.
1299 * A wide variety of instrumentation was added including the
1300 ability to produce a stack trace from within afsd_service.exe
1303 * Dynamic configuration of the RDRtimeout value based upon the
1304 LanMan Workstation Session Timeout
1306 * The mount root no longer needs to be called "/afs". This
1307 is now set by a registry value "MountRoot" within the key
1308 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1310 * The cell list is now only read out of afsdcell.ini when the
1311 file changes instead of each time a cell is resolved.
1313 * Thread synchronization was added to cm_server.c and ktc_nt.c
1315 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1316 calloc()/free(). The Global functions were needed on Windows 3.x
1317 but have caused a variety of problems on the Win32 platforms.
1318 Avoiding them is highly recommended by several Microsoft
1319 Knowledgebase articles
1321 * Support for Symbolic Links added to the AFS Shell Extension
1323 * Added a registry value "OverlayEnabled" to determine if
1324 Shell Extension Overlays should be enabled.
1325 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1327 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1328 separate trees for checked and free builds. Build system supports
1329 a custom directory src\WINNT\extra which can be used as a grafting
1330 location of organization specific additions to the build tree.
1332 * New installer built using NSIS 2.0.
1334 * Named all kernel objects in order to allow them to be monitored
1335 with tools such as SysInternals' ProcExp.exe.
1337 * Introduced new EventLog framework for AFSD
1339 * Introduced Power Management interface to AFSD for Standby and
1340 Hibernate modes to allow cache to be flushed prior to network
1343 * Utilize Win32 DNSQuery API instead of internal routines. This
1344 allows DNS SRV queries to be sent to all current domain name
1345 servers. Not just one specified in an INI file. DNS is now
1348 * "NetbiosName" registry value may be used to specify a fixed
1349 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1350 when the loopback adapter is in use. If you need to use the
1351 old notation with a loopback adapter installed specify a registry
1354 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1356 * Refactor all modules which depend on LAN Adapter and NetbiosName
1357 determination in a new library: lanahelper.lib. This allows for
1358 consistent behavior throughout the product.
1360 * Move the afsd.log and afsd_init.log files to the directory specified
1361 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1362 for services. Added the Date to the log entries.
1364 * New registry value "RxMaxMTU" used to limit the size of the RX
1365 packets sent by the AFS Client Service to the Server. In order
1366 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1367 size must be restricted to 1264 or smaller. The latest NSIS
1368 installer sets a value of 1260 by default.
1370 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1371 packets. This is not needed in order to work across the Cisco
1372 VPN but might be needed for other network environments. This
1373 value is not set by the NSIS installer.
1375 * New registry value "HideDotFiles" is used to apply the Hidden
1376 attribute to files whose names begin with a '.'. This value
1377 is set by the NSIS installer.
1379 * New registry value "MaxMpxRequests" allows the maximum number
1380 of multiplexed sessions to be configured at run time. This
1381 value is not set by the NSIS installer. The default value is
1384 * New registry value "MaxVCPerServer" allows the maxmimum number
1385 of VCs per server to be configured at run time. This value is
1386 not set by the NSIS installer. The default value is 100.
1388 * New registry value "AllSubmount" allows the "all" submount to
1389 be disabled by setting its value to 0x00.
1391 * Allow cells names to be valid mount points
1392 \\<netbiosName>\<cellname>
1394 * Store the active state of drive mappings in order for afscreds.exe
1395 to restore them upon startup
1397 * Add exception handling to generate a Stack Trace to the afsd_init.log
1398 file if one happens to occur.
1400 * Add lots of logging to help detect the cause of invalid SMB packets
1402 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1403 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1404 renewal of expiring tokens as long as afscreds.exe is running.
1406 * New afscreds.exe command line options:
1408 -M = renew drive maps
1409 -N = ip address change detection
1412 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1413 determines whether or not MIT Kerberos for Windows should be used
1414 to obtain tokens via Kerberos 5 tickets.
1416 * New registry value "AfscredsShortcutParams" in
1417 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1418 determines the command line parameters to be specified when "fixing"
1419 the AFS Shortcut in the user's startup folder.
1421 * The "ShowTrayIcon" registry value has been moved from
1422 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1423 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1425 * The <cell name> registry values used to store the token expiration
1426 reminders have been moved from
1427 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1428 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1430 * Obtain the Logon User Name from the Explorer key when available
1432 * new text document doc\txt\winnotes\registry.txt lists all registry
1433 values used by OpenAFS (excluding the AFS Server)
1435 * BUG: rx_securityClass objects were not properly reference
1436 counted and were never freed.
1438 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1439 would be generated. The existence of a server does not imply
1440 that it is not down. If all of the servers for a cell are down
1441 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1444 * BUG: the directory name lookup cache failed to free the entries
1445 in the cache when the name cache entries cycled. The entries
1446 in the cache would become dereferenced without being freed.
1448 * BUG: fs setserverprefs could be executed without Administrator
1451 * BUG: the number of allocated NCB objects (100) exceeded the number
1452 which could actually be waited upon by the kernel (64). Any objects
1453 which were utilized above the limit could never have event completions
1456 * BUG: smb_username_t objects were not being reference counted and
1457 were not properly freed.
1459 * BUG: smb_tid_t objects could under unusual circumstances be freed
1460 before they were no longer referenced.
1462 * BUG: smb_fid_t object pointer were frequently used even when
1463 their value could be NULL. They were not properly released and
1464 therefore they were never freed.
1466 * BUG: smb_packet_t data structures were not completely initialized
1469 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1470 Denied" because that causes the Explorer Shell to try again until
1471 access is obtained. Instead return "Remote Resources" which allows
1472 the shell to move on and treat the error as transient.
1474 * BUG: when initializing the NCBreturns structure, separate Event objects
1475 were created for each NCB although a single Event object was supposed
1476 to be shared by all.
1478 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1481 * BUG: smb_tran2Packet_t objects were not being properly referenced
1484 * BUG: directory path creation did not handle the case of multiple
1485 directories requiring creation in one attempt
1487 * BUG: SMB requests which required an Extended Response were ignored.
1488 This prevented some files from being written to AFS volumes.
1490 * BUG: character strings were being freed even after they were
1491 inserted into in use data structures
1493 * BUG: inconsistent usernames were used when High Security mode was
1494 enabled. (there is still much to do in this area)
1496 * BUG: pioctl() calls which require out of band RPC operations were
1497 susceptible to race conditions when performed by multiple processes
1499 * BUG: memory allocation and deallocation crossed instances of the
1500 C Runtime Library producing memory leakage and corruption in
1501 afscreds and the client configurator.
