2 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
3 the process of producing AFS tokens. The tokens are stored within
4 the AFS Client Service but the Kerberos 5 tickets have been discarded.
5 New functionality has been added to temporarily copy the tickets to
6 a file ccache during the short window between the NPLogonNotify and
7 WinLogon Logon Event. The Logon Event handler starts a process as
8 user, afscpcc.exe, that copies the tickets into the default ccache.
9 The file ccache is then destroyed by the event handler.
11 * During synchronization operations on stat cache entries, if threads
12 are forced to sleep it was possible that the threads would not be
13 woken under heavy load.
15 * Enforce the delete on close flag specified by the NTCreateX()
18 * A race condition in the rx library was fixed that resulted in
19 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
20 was cleared when threads were still waiting to use the
21 connection. Also, fixed a potential case in which the
22 connection could be destroyed while threads were waiting to use it.
24 * The DNLC freelist has been seen to become corrupted with still
25 active entries being stored on the freelist. Changes were made
26 to perform a better job of cleaning entries before placing them
27 onto the freelist; marking them with the correct magic value when
28 purging the list; and allowing the list to be purged on startup
29 if the cache validation fails.
31 * Windows Crash Reporting does not get triggered for afsd_service.exe
32 because it provides its own top level exception handler. This patch
33 places an explicit call to ReportCrash() on platforms which support
36 If you configure Crash Reporting via AD Policy to capture crash
37 reports within the domain, then you will receive this output.
39 * Generate MiniDumps independent of the Windows Crash Reporting.
41 (a) If an exception occurs,a minidump will be generated at the path
42 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
43 can be set to any other type via use of the
46 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
48 (b) MiniDumps can be generated at any time using the "fs minidump"
49 command. This allows you to generate a minidump without
50 stopping the process or even requiring the use of a debugger
53 * an RX connection which reports bad ticket now treats it the same way
54 the expired ticket is treated. The ticket is removed from the
55 connection and a new anonymous connection is established.
57 * fs memdump now requires that the caller be in the AFS Client Admins
60 * additional debugging information is provided in cm_Analyze when the
61 error code is ignored.
63 * Fix a regression introduced into the pioctl() client code which
64 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
65 MIT KFW is not installed. (1.3.82a)
67 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
70 * Fix a race condition in cm_EndCallbackGrantingCall() that
71 could leave 'nrevp' pointing to freed memory. In the process,
72 optimize the processing to ensure that the applications monitoring
73 the status of the stat cache entry are only notified at most
76 * Conditionalize access to the Explorer Shell AFS->Mount Point
77 ->Remove menu item. Disable the item if the selected item(s)
80 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
81 Local Storage. This eliminates thread contention on the
82 global RX free packet queue. This should improve performance
85 * Fix the IP address filtering code to properly load/unload
86 the IPHelper DLL so that Windows XP/2003 and beyond systems
87 do not have to manually probe the registry.
89 * CleanupACLEnt() was not being called consistently with
90 the cm_scache_t object referred to by the back pointer
91 mutex locked. This could in very rare conditions lead to
92 an invalid memory access.
94 * Added a script command to the msi installer "afs_replace"
95 which can be used to replace one version of OpenAFS with
96 another without requiring an uninstall and reinstall if
97 the installed msi is no longer in its original location.
99 * Apparently the problem with multi-domain forests with cross-
100 realm trusts to non-Windows realms was not entirely solved.
101 The authentication to the AFS SMB service failed because
102 the wrong name was being used. Using ASU as an example,
103 the authentication was being performed with the name
104 "QAAD\user" (an account in the forest root) and not
105 "user@ASU.EDU (the MIT Kerberos principal used to login with)
107 The solution was to add an additional dependency on KFW
108 in order or to be able to easily obtain the client principal
109 name stored in the MSLSA ccache TGT. This information is
110 used in two locations:
112 - the pioctl() function
114 - a new WinLogon Event Handler for the "logon" event.
116 The pioctl function will now be able to use the correct
117 name when calling WNetAddConnection2() and the "logon"
118 event handler will now be able to call WNetAddConnection2().
119 The hope is that the "logon" event handler will be called
120 before the profile is loaded but I have not guarrantee
124 * Fixed a locking error in cm_TryBulkStat() which had the
125 potential of deadlocking the system for the length of time
126 it takes to perform a bulk status fetch operation.
128 * Replaced time conversion code (UnixTime <-> FILETIME) to
129 be completely arithmetic instead of relying on a bizarre
130 algorithm involving a variety of C RTL time functions.
131 This has the side effect that UnixTime and FILETIME which
132 are both stored in UTC are interpretted as UTC throughout
133 the year. Windows will apply the same localization to AFS
134 as it does to NTFS. Applications which rely on the ability
135 to sync files between the two file systems will no longer
136 see the timestamps of files in AFS change an hour relative
137 to the files stored in NTFS or Windows based backup devices.
139 * Fixed a invalid memory access under a bizarre circumstance.
140 Windows will allow a physical mass media device to be
141 installed via Plug N Play to the system and will assign it
142 the lowest available drive letter. This is true even if the
143 drive letter is currently assigned in the user session to
144 a network device via NET USE (or its equivalent.) When this
145 happens, queries sent to the CIFS server will contain invalid
146 data. This invalid data was not being caught by the AFS
147 Client Service and was resulting in a crash when Freelance
150 * Fixed a reference count error when registering callbacks
151 on a stat cache object if the callback was already registered
153 * Add a case to cm_Analyze() in order to handle the case where
154 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
155 the server list for the volume is empty. In this case, force
156 an update of the volume info and retry.
158 * Insert a missing cm_EndCallbackGrantingCall() which could
159 result in threads waiting for a callback to complete to never
162 * In the persistent cache, there is a maximum number of volume
163 entries. Allow volume entries to be reused if the maximum
164 number have been allocated and their reference count is zero.
166 * If we already have a dead virtual connection object, don't
167 ignore the fact that additional dead vc objects must be taken
170 * Removed a deadlock condition introduced in the summer of 2004.
171 Do not hold mx locks around calls to RX functions including
172 rx_NewCall(). That is what reference counts on the rx_connection
175 * Fixed an initialization error in afslogon.dll which could
176 result in random behavior including a failure to terminate
177 the NPLogon function. (1.3.80b)
179 * Fixed an error preventing the use of SMB authentication
180 on Windows 2000. (1.3.80a)
183 * Updated CellServDB to Public CellServDB 16 Mar 2005
185 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
186 misinterpretted as "csail.mit.edu" when the resolver
187 is configured to append ".mit.edu" to failed DNS queries.
189 * Fixed another case in which the client would replace connections
190 to the host when it was not necessary. In this case the
191 situation would occur if cryptall was on and the connections
192 were unauthenticated due to lack of an appropriate token.
194 * OpenAFS for Windows has failed to work at sites which are
195 utilizing a cross-realm trust between an MIT/Heimdal realm
196 and a multi-domain Windows forest when the workstation being
197 accessed is not located in the root domain. This is caused
198 by a bug in the workstation which was triggered after the
199 introduction of Windows 2003 Server. When the bug is triggered,
200 the workstation attempts to authenticate users to afsd_service.exe
201 by contacting the Domain Controller instead of using the
202 LSA loopback authentication mechanism.
204 One of the reasons this bug occurs is because the workstation
205 does not have a reliable way of knowing that the service whose
206 netbios name is "AFS" is located on the workstation. This will
207 be fixed starting in Longhorn Beta 1 by Microsoft. The
208 "BackConnectionHostNames" registry value will be used to
209 indicate that the authentications to that service name should
210 be performed using the loopback authentication mechanism.
212 In the meantime, when Logon Caching is enabled, we can force
213 afsd_service.exe to authenticate using the logon cache before
214 contacting the Domain Controller. This will work with both
215 password and smart card based logons.
217 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
218 flag should not be cleared if a volume's server reference is
219 marked as "offline". In the case where all of the volume's
220 servers are either "down" or the volumes are "offline", we want
221 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
222 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
223 should never occur in practice.
225 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
226 5 seconds, clear the server down and volume busy flags, and
227 then force an update from the VLDB. This allows the client to
228 update the location of a volume if the reason for it being
229 marked offline is because it is being moved. Calls to
230 cm_ConnByMServers() will be retried either until success or
231 the RDRtimeout period is reached.
233 * Correct the Power Management code behavior in response to
234 Standby, Suspend, and Shutdown events. Instead of flushing the
235 buffers associated with the mounted SMB submounts, simply write
236 all buffers which are marked dirty.
238 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
239 provides a list of cells other than the default cell for which
240 tokens should be obtained using the default Kerberos principal.
241 This functionality is logon domain specific and is only available
242 when using KFW for authentication.
244 * Fixed FindNext Invalid Handle error caused by over agressive
245 attempts at garbage collecting dirSearch entries when the
246 dirSearch ID wraps from the maximum value to 1.
248 * Add support for registry defined server preferences for VLDB and
249 File servers. See registry.txt for details.
251 * Increased default cache size to 96MB and default number of cache
254 * Fixed refCount leaks related to directory lookups and pioctl calls.
256 * Callbacks revoked during a race condition with an attempt to
257 obtain the same callback no longer result in an inaccessible
260 * New command line tool:
262 afsdacl : Set or reset the DACL to allow starting or stopping
263 the afsd service by any ordinary user.
265 Usage : afsdacl [-set | -reset] [-show]
267 -reset : Reset the DACL
268 -show : Show current DACL (SDSF)
270 * IP addresses are no longer queried once at startup. Instead IP
271 addresses are obtained as needed. Loopback adapter addresses are
272 no longer published to the server.
274 * Pay attention to the MIT KFW registry configuration for automatic
275 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
277 * Fix (once again) case-sensitive comparisons which was apparently
280 * Activate support for vos listvol -format
282 * Population of the "AFS Client Admins" group failed on non-English
283 versions of Windows because the name of the "Administrators" group
284 is localized. Now we lookup the name of the group by using the
285 Administrators Group Alias Relative ID.
287 * Multiple cell token acquisition within afscreds.exe was broken in the
288 case of Kerberos 5 cross realm authentication. Instead of contacting
289 the KDC associated with the cell's realm, afscreds would obtain a
290 token from the KDC of the user's realm. This would result in
291 "invalid kvno errors" while authenticating to the AFS servers.
292 Unauthenticated access would work. The symptoms would vary based upon
293 whether or not the VLDB servers had been contacted using unauthenticated
294 connections prior to the user obtaining tokens.
296 * The list of ACL entries was becoming corrupted. It appears as if
297 an ACL when it expires was not being appropriately cleaned up. In
298 fact, it was left in the list of ACLs associated with the scache
301 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
302 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
303 and "amd64_win64" for amd 64-bit processors.
305 * When executing executables, Windows provides a mechanisms by which
306 the normal search for DLLs can be bypassed. If a file foo.exe is
307 being executed and there exists a file or directory "foo.exe.local"
308 (the contents are ignored if a file), then Windows will search for
309 DLLs first in the "foo.exe.local" directory and second in the
310 directory in which the "foo.exe" file is located.
312 Previous releases of OAFW would improperly return
313 STATUS_NOT_A_DIRECTORY instead of the expected
314 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
315 to terminate the search for the DLL causing the execution of the
318 * Rework the reference counting of smb_vc_t objects. The references
319 stored in the waiting locks were not counted. This could result in
320 an assertion if the reference count drops to zero.
322 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
323 when running in freelance mode.
325 * Added support for persistent caching of file contents, stat entries,
326 volume data, cell data, and name lookup data. When the registry
327 value, "NonPersistentCaching", is not defined or set to 0 the file
328 specified by "CachePath" becomes a persistent cache file. The
329 size of the cache file is computed at run time. It has a maximum
330 size of approximately 1.2GB. The contents of the file will be
331 validated according to the rules specified by the "ValidateCache"
334 * Added support for UUIDs. UUIDs are kept for as long as the
335 cache file is intact.
337 * Added cmdebug.exe and support cache manager debugging callback
338 interfaces in afsd_service.exe.
340 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
341 [-addrs] [-cache] [-help]
342 Where: -long print all info
343 -addrs print only host interfaces
344 -cache print only cache configuration
346 * Symlinks to \\AFS\[all\]... will now be treated the same as
347 symlinks to /afs/.... However, please use /afs/... as otherwise
348 the symlinks won't work on Unix.
350 * Correct a problem with local CellID allocation for cells whose
351 server list is obtained via DNS instead of a CellServDB file. If
352 the DNS information expires the CellID assigned to the entry will
353 be changed. This causes all of the cm_scache_t objects which refer
354 to the old cellID number to become useless. Attempts to access
355 files or directories with cm_scache_t objects using the old cellID
356 will fail since the server list cannot be obtained.
358 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
359 be triggered if the volume referenced by the cm_scache_t object is
362 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
363 in addition to SERVICE_ACCEPT_STOP.
365 * Move RPC shutdown until after the SMB and RX shutdown procedures
366 complete. Block until RPC shutdown is complete.
368 * Modify afslogon.dll (integrated logon) to wait for service if its
369 state is START_PENDING. If the timeout period occurs, reset to
370 the retry interval and not the sleep interval.
372 * When renewing the server list for a cell obtained via DNS AFSDB
373 records, the cm_cell_t entry must be removed from the list of all
374 cells. Otherwise, the list of cells will be corrupted.
376 * In the dcache and scache modules, use the cm_scache_t dataVersion
377 instead of the cm_fakeDirVersion.
379 * Synchronize fs.c with the unix version.
381 * The variable used to determine whether a file or virtual memory
382 mapped cache is used was not properly initialized to a default
383 value. If the registry setting "NonPersistentCaching" was not
384 set, the choice would be random. Properly initialized to be
387 * The memory mapped view was never unmapped before closing the file
388 at service shutdown. This is now properly cleaned up.
390 * Default location of Cache file is now %TEMP%\AFSCache
394 * A bug affecting new installations of 1.3.75/76 would result in
395 the creating of incorrect mountpoints in the freelance root.afs
396 volume for the default cell.
398 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
399 of "root.cell", you have been affected by the bug. To correct the
400 problem, execute the following commands:
402 fs rmmount \\afs\all\<cellname>
403 fs rmmount \\afs\all\.<cellname>
405 fs mkmount \\afs\all\<cellname> root.cell <cellname>
406 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
410 * A bug has been fixed in the auto-generation of Freelance root.afs
411 symlinks which produced random entries in the \\AFS\all directory.
413 * Support has been added for multi-homed servers
416 * Added a new registry value, "StoreAnsiFilenames", which can be used
417 to force the use of ANSI character sets instead of OEM Code Pages.
418 This feature is useful when users require the ability to create
419 filenames with 8-bit characters and need to access the files from
420 both Latin-1 based Unix systems as well as from Windows.
422 Activation of this feature will prevent access to files stored with
423 8-bit OEM characters.
425 * Shutdown all SMB threads in a synchronized manner when stopping the
428 * There is currently a maximum cache size of 1.3GB. The limit is imposed
429 by the largest contiguous block of unused memory within the 2GB process
430 space which can be assigned to the memory mapped file. Unfortunately,
431 when the executable digital signature verification code is activated
432 Windows sees fit to further segment the process memory which in turn
433 reduces the size of the maximum cache file to less then 800MB. If
434 larger cache sizes are desired, a new registry value should be set:
436 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
438 Setting this value will disable the runtime verification of digital
439 signatures on afsd_service.exe and the afs dlls which it loads. It
440 will not disable the the version number check on those same files.
441 The signature verification is not a security messure and is only meant
442 to enhance the ability to afsd_service.exe to detect potential
443 destablizing mixtures of DLLs from incompatible distributions.
445 Added code to auto-disable the signature verification check if
446 the desired cache size is greater then 700MB.
448 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
449 used to verify the validity of the afsd_service.exe binary
450 as well as each of the AFS DLLs loaded by the service. Not only
451 must the digital signature be valid but the signatures of the
452 DLL must be signed by the same entity as the service.
454 * Implement new functions: cm_freelanceMountPointExists and
455 cm_freelanceSymlinkExists. Use them along with other validity
456 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
457 ensure that name collisions do not occur and that empty strings
458 are not valid file names.
460 A symlink may not have a name which would resolve to a valid
461 cell name. Doing so would prevent access to the cell.
463 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
464 re-initialization code. The reference counts of the fake root.afs
465 volume scache object(s) would become invalid when the mount point
466 or symlink lists were altered.
468 * Add registry entries to provide mappings from the afsdsbmt.ini
469 to the new locations for applications which count on the use
470 of the old Profile file APIs. These apps are likely to fail
471 if the user does not have administrator privileges and the
472 registry is locked down.
474 * The afs_config.exe submounts dialog had two errors.
475 First, attempts to remove entries failed because the registry
476 key was being opened without KEY_WRITE privileges.
477 Second, when editing a submount entry, changing the name
478 would add a new key and leave the original one in place.
479 Now the original submount will be removed if its name is
482 * In recent months there have been several incidents in which
483 users have experienced problems starting or accessing
484 afsd_service.exe and after significant effort has been spent
485 it has turned out that they have two versions of AFS on the
486 machine or an inconsistent set of DLLs.
488 Code has now been added to afsd_service.exe which will walk
489 the list of modules loaded by afsd_service.exe and validate
490 that the version of the AFS DLLs matches the version of the
491 afsd_service.exe executable. If they do not match the service
494 * When Freelance mode is enabled and there is no registry
495 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
496 will attempt to import the afs_freelance.ini file contents.
497 If the file does not exist, it was creating a dummy file
498 with a r/o and r/w entry for the default cell and then
499 importing those values.
501 This process has been changed. The temporary file is no
502 longer created. Also, both the OpenAFS Client install
503 directory as well as %WINDIR% are checked for previous
504 afs_freelance.ini files.
506 * Added support for VL_GetEntryByNameN(). Still need to add
507 support for VL_GetEntryByNameU() for multi-homed support.
509 * Fix a deadlock situation in afscreds.exe when canceling an
510 auto-generated Obtain Tokens dialog
513 * Fix the locking of objects during Directory Searches in the
514 SMB/CIFS server. The failure to properly lock the reference
515 counts was resulting in the premature freeing of smb_dirSearch_t
516 objects while they were still in use by the SMB/CIFS client.
517 This does not solve the "Invalid Handle" problem.
519 * Fix Find Cell By Name pioctl call to return a valid cell
520 name for the Freelance fake root.afs volume.
521 "Freelance.Local.Root".
523 * Fix the Explorer Shell Extension Symlinks->Add operation.
524 The dialog template was missing and the link destination
525 string was too short.
527 * Add support for symlinks to Freelance root.afs volume
528 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
529 <number> = "<linkname>:<relative-path>."
530 Use symlink.exe to create, list, or remove
532 * Remove the fallback to the use of KFW's KRB4 library when obtaining
533 tokens. We never obtain KRB4 tickets.
535 * Fix AFS Client Configuration Control Panel to support new SysName
538 * Fix a bug in afsd_service.exe which could result in the SysName
539 not being read from the registry.
542 * Add code to block the issuance of AFS tokens by aklog.exe or
543 afscreds.exe when the Kerberos 5 principal name contains a dot.
545 * Modify the IsAdmin() function to always treat the local SYSTEM
546 account as an AFS client administrator. Affects fs.exe and
549 * Modify the internal handling of Quota Exceeded errors
551 * Upgrade all reference count fields in the Windows cache manager
552 and the osi library to use unsigned long instead of signed short.
553 A similar fix has been applied to the afs rpc (rx) library.
555 * fix the Windows cache manager to prevent it from replacing the
556 rx_connection object associated with the cm_conn_t object on each
557 and every operation if "fs crypt" was set. This explains the
558 dramatic performance difference when crypt is used vs clear.
559 The problem: 'cryptall', a boolean flag indicating whether or not
560 "fs crypt" is set, was being compared to the rx_connection
561 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
562 1 != 2 and therefore the rx_connection was always destroyed
563 and replaced on each and every operation.
565 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
566 It is not safe for the cm_conn_t object to not be locked because
567 rx_DestroyConnection might be called from another thread if:
568 - the user's tokens have changed or expired
569 - the crypt mode has changed
571 This fix appears to have also taken care of the problems associated
572 with Overlapped Writes resulting in Delayed Write errors.
574 * fix NSIS installer's AdminGroup.exe to properly create and
575 remove groups when given -create or -remove. The string comparison
578 * fs sysname now accepts a list of sysname values
580 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
581 DWORD which when set to a non-zero value will cause error message
582 text to be output to stderr from the pioctl() routine. Useful in
583 debugging failures of fs.exe, tokens.exe, etc.
585 * added a test to the power management code to only perform a
586 flush operation if there is at least one network adapter which
587 is not a loopback adapter.
589 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
590 "EnableKFW". This value will not be read if the key
591 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
592 value under that key does not.
594 * provide mechanisms to force the use of krb524d for Kerberos 5
595 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
596 there is a new registry value "Use524" and for aklog.exe a new
597 command line parameter "-m".
599 * Fix the pattern matching algorithm to properly match patterns
602 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
603 which is used by both the original function and the new
604 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
605 creation of HardLinks in addition to Renaming. smb_Link()
606 is a new function which creates HardLinks via cm_Link().
607 cm_Link() is a new vnodeops function which creates links
610 smb_ReceiveNTRename() does not support the File Copy and
611 Move Cluster Information operations described in its interface.
612 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
614 * When opening files via symlinks, we should follow the symlinks
615 until we reach the actual file stat cache entry. The stat cache
616 entry of the file should then be stored in the FID instead of
617 stat scache entry of the symlink.
619 * return bad operation errors for all unimplemented functions
620 even if we do not know the functions exist.
622 * Log bad packets and unknown operation packets to the trace log
624 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
627 * Update list of known CIFS operations to include all those listed
628 in CIFS-TR-1p00_FINAL.pdf.
630 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
631 to support the REG_EXPAND_SZ type.
634 * A new Windows authorization group "AFS Client Admins" is now
635 created and populated with the members of the "Administrators"
636 group. The group is used to determine which accounts on the
637 machine may be used to modify the AFS Client Configuration via
638 the UI and command line tools. afs_config.exe, fs.exe,
640 * Modify the WinLogon Logoff Event Handler to query NT4 domain
641 controllers for the remote profile path if Active Directory
642 services are not available.
644 * Fix aklog.exe to not add the AFS ID to the username
646 * PTS registration of new users to foreign cells has been added to
649 * The cm_Daemon thread is used to perform checks for
650 down servers, up servers, volumes, callback expirations,
651 lock maintenance and token expiration. Due to a gaff in
652 larger integer division the thread never performed any
653 work. Instead the current time computation would always
654 be less then the trigger times. This had an adverse affect
655 on the client's ability to maintain communication with servers,
656 keep volumes up to date, and flush user tokens and acls
657 when they have expired. This was broken when the 1.3 branch
658 was modified to support VC7 which no longer included
661 * An initialization problem with the Freelance code was
662 detected while fixing the callbackRequest. The cm_rootSCachep
663 object is obtained during afsd_InitDaemons() but the callback
664 information is incomplete. The callback information will not
665 be obtained until cm_MergeStatus is called from within
666 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
667 test for the conditions under which the callback information
670 * Reports have been filed indicating that callbacks were
671 being lost. An examination of the code indicated that the
672 cm_server_t objects were not being properly reference
673 counted by the cm_scache_t and cm_callbackRequest_t objects.
674 In particular, the cm_server_t objects may have been freed
675 from beneath the cm_conn_t objects.
677 All of the reference counting is now done via the functions:
682 this improves the ability to track the referrals.
684 Each cm_BeginCallbackGranting Call now allocates a reference
685 to the cm_server_t. The cm_EndCallbackGrantingCall either
686 frees the reference or transfers it to the cm_scache_t
687 cbServerp field. These are then appropriately tracked
688 through the cm_Analyze call.
690 * Ensure that the dnlc hash table is the same size as the
691 dir name hash table (as per original author's note).
692 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
693 for compatibility with 64-bit systems.
695 * fix smb_ApplyV3DirListPatches to properly apply the hidden
696 attribute to dotfiles when the infoLevel < 0x101 and
697 cm_SyncOp has failed.
699 * Fix the Freelance registry initialization code. There
700 was a possibility that some systems could end up with
701 garbage in the registry during a clean install.
704 * file and directory names beginning with "." will now be given the
705 hidden attribute when the volume access is anonymous. this matches
706 the behavior when the volume access is via an authenticated user.
708 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
709 key. When a change occurs mark the root.afs data as invalid and
710 for it to be reloaded on the next access. This allows administrators
711 to modify the mount point list without restarting the service.
713 The freelance client used to provide a fake modification time for
714 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
715 Added code to extract the last modification time of the Freelance
716 registry key and use that instead. The time now represents the
717 most recent mount point change.
719 * PTS registration of new users to foreign cells has been added to
722 * Additional Cache Control and Credential Manager options have been
723 added to the WiX installer. See deployment guide for details.
725 * The CachePath setting is now optionally a REG_EXPAND_SZ type
727 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
730 * The loopback installation code may have had a problem updating the
731 %ETC%\HOSTS file which could have resulted in a premature failure.
732 Work around code has been added for the case where the file cannot
735 * The default max chunksize was increased from 15 (32K) to 17 (128K)
736 because Windows sends 64K blocks when using overlapped writes.
738 * The default number of server threads was increased from 4 to 25 to
739 better handle overlapped writes.
741 * The "AfscredsShortcutParams" registry value was not being properly
742 loaded by afscreds.exe. Therefore, the default value was always being
743 used instead of the value set by the installer.
745 * Windows XP provides downgrade attack detection to prevent an attacker
746 from being able to force the use of NTLM simply by disrupting
747 communication with the KDC. This attack cannot exist between the
748 Windows CIFS client and the AFS Client Service. Therefore, when a
749 downgrade has been detected the afs pioctl library will force the
750 establishment of a new CIFS connection using NTLM.
752 * A locking error was discovered surrounding all references to volume
753 server lists within the cm_cell.c source file.
755 * The logged into Windows username was incorrect on Terminal Server
758 * A new registry value "NonPersistentCaching" was added to the service
759 parameters key. When set to a non-zero value, the afs cache is stored
760 in the Windows paging file. There are two limitations to choosing
762 1. when persistent caching is implemented it won't work with
763 this flag set since there will be nothing to persist.
764 2. with this flag set the initial paging allocation cannot be
765 changed while the service is running
767 * An initialization bug was discovered in aklog.exe which affected users
768 who have a domain name for their afs servers which could not be mapped
772 * afs_config.exe now validates cell names against DNS in addition
773 to the CellServDB file.
775 * In order to allow the freelance client to connect to a volume with ID
776 equal to 1 on the default cell we changed the fake root.afs volume ID
777 once again. This time we choose 0xFFFFFFFF. In addition, we change
778 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
779 It will now be impossible for a volume ID to match that of another
780 cell unless the client is connected to 0xFFFFFFFD cells. That should
781 be enough room for growth.
783 * Fix "fs mkmount" command to work with UNC paths and when
784 started from non-AFS drives. It is now possible to create a mount
785 point in the freelance fake root.afs volume with the command
787 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
791 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
792 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
794 * The algorithm used to re-attempt access to the servers associated with
795 a volume has been altered to properly address the case in which all
796 servers have been marked down. The previous algorithm did not reset
797 the server's down flags so the servers were never actually retried.
798 This caused a problem with active volumes if the network connectivity
799 was lost as could be the case with a network cable removal, wireless
800 drop, or laptop hibernation. With the fix volume access is restored
801 almost instantenously when network connectivity becomes available.
803 * Support for SMB/CIFS browsing has been added to the AFS Client Service
804 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
805 listing of AFS submounts and freelance mount points. Support for
806 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
807 significantly enhances the behavior of AFS volumes within the Explorer
808 Shell. For instance, "AFS" now shows up as server in the Explorer
809 with each submount or freelance mount point visible as a share.
810 The right click menu in each folder now works with full functionality
811 on a consistent basis.
813 * The network provider can be configured to have different behavior
814 depending on the domain that the user logs into. These settings are
815 only relevant when using integrated login. A domain refers to an
816 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
817 local machine (i.e. local account logins). The domain name that is
818 used for selecting the domain would be the domain that is passed into
819 the NPLogonNotify function of the network provider. (see registry.txt
822 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
823 "Authentication Cell" which may be used to specify a default
824 authentication cell for afscreds.exe which is different from
825 the default cell for the AFS Client Service daemon.
827 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
828 afslogon.dll moved to %WINDIR%\System32\.
829 New registry entries added to register the dll for Winlogon events.
831 The logoff event will now force a call to ktc_ForgetAllTokens()
832 using the context of the user being logged off as long as the
833 user's profile is not loaded from within AFS. If the profile
834 was loaded from AFS we can't release the tokens since the Logoff
835 event is triggered prior to the profile being written back to
836 the its source location. This is now performed in an XP SP2
839 * Windows XP SP2 Internet Connection Firewall interoperability
842 * The %WINDIR%\afsdsbmt.ini contains four sections:
843 Submounts, Drive Mappings, Active Maps and CSC Policies.
844 The Submounts and CSC policies are now stored in the registry under
845 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
846 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
847 The Drive Mappings and Active Maps are stored in the registry under
848 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
849 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
851 There is no automatic migration of this data as it would be impossible
852 to consistently migrate data to user profiles which may not be active
853 when the machine is updated.
855 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
856 fake root.afs volume. For the same reasons as for the cellservdb file,
857 this information should not be in %WINDIR%. This information is now
858 kept under the registry key
859 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
861 The data from the afs_freelance.ini file will be automatically
862 migrated to the registry on first execution of afsd_service.exe
864 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
865 troublesome for several reasons. One, it is confusing for those who
866 expect the file to be named "CellServDB" instead of "afsdcell.ini".
867 Two, this file is not a Windows Profile formatted file. Three,
868 applications should not be reading or writing to %WINDIR%. It causes
869 problems for Windows Terminal Server.
871 The new location of CellServDB will be the OpenAFS Client install
872 directory which is by default C:\Program Files\OpenAFS\Client and can
873 be determined by querying the registry for
874 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
876 The existing afsdcell.ini will be migrated by the NSIS installer.
877 The Wix installer must still be updated to do the same.
879 * Change NSIS installer to use DNS by default; to remove Integrated Logon
880 High Security mode; and to add Terminal Services compatibility registry
881 entries to allow the OpenAFS tools to find the afsdcell.ini and other
882 configuration files in %WINDIR%.
884 * Add support for authenticated SMB connections. This will remove
885 the need for high security mode in most situations. Both NTLM
886 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
887 only NTLM can be used even though Kerberos is now supported. The
888 reason is that it is not possible to construct a service principal
889 which is unique to each individual machine.
891 SMB Extended Auth does not work on XP SP2 unless one of two registry
892 modifications are made:
894 (1) To disable the check for matching host names on loopback connections
895 set this key. This does not require a reboot:
897 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
898 "DisableLoopbackCheck"=dword:00000001
900 (2) To add the AFS SMB/CIFS service name to an approved list. This
901 does require a reboot:
903 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
904 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
906 afsd_service.exe will automatically add the current Netbios Name
907 to the BackConnectionHostNames list and then temporarily disable
908 the loopback check for one cycle of startup/shutdown of the service.
909 We assume most folks do not start/stop without a reboot so this
910 will be adequate in most cases.
912 * Fix security hole in afslogon.dll which allowed passwords to be
913 sent in clear text to the KDC in a misformed principal name.
915 * Fix cm_GetCell() to properly handle expired dns entries
918 * If Freelance mode is active and the afs_freelance.ini
919 file does not exist, do not create an empty file.
920 Instead create a file containing ro and rw mountpoints
921 to the default cell using the standard conventions.
923 * Modify the Freelance support to handle the ability
924 to create rw mount points in the fake root.afs volume.
926 * Changed the RPC mechanism used for token setting from
927 named pipes to local. Use of named pipes can be restored
928 by setting the environment variable AFS_RPC_PROTSEQ to
931 Named pipes were required when a Windows 9x system was
932 using a NT system in gateway mode which is incompatible
933 with our use of local loopback adapters.
935 * In afscreds.exe, if a username of the form user@REALM is
936 specified and no password is specified, do not perform a
937 kinit operation. Only perform the aklog functionality.
939 * Add a new registry value which allows the number of processors
940 on which afsd_service.exe executes to be restricted. Valid
941 values are 1..numOfProcessors
943 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
947 * A second MSI based installer option is now available.
949 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
950 request tickets for user/instance@REALM instead of just user@REALM
952 * Modify the Power Management Notify routine to wait for the Hard Dead
953 timeout period instead of a fixed 19 seconds. With the longer timeout
954 periods Hibernation and Standby could never succeed when network
955 connectivity is not available.
957 * The following fs.exe commands are now restricted to Administrator:
958 - checkservers with a non-zero timer value
961 - sysname with a new sysname list
970 setting the default sysname for a machine should be done via the
971 registry and not via "fs sysname".
973 * NSIS installer adds options to install Debugging Symbols
974 and the Microsoft Loopback Adapter; the user is now also
975 given the ability to select the afscreds.exe startup options.
977 * Build system modified to generate symbols for FREE (aka RELEASE)
978 builds as well as CHECKED (aka DEBUG) builds
980 * Sites which have a volume ID of 0x20000001 assigned to their
981 root.cell volumes have been experiencing problems with accessing
982 the root.cell volume of their cell when Freelance mode has been
983 active. This was because 0x20000001 was assigned to the fake
984 root.afs volume created by freelance. The fake volume id is
985 now set to 0x00000001 to prevent conflicts.
987 * The timeout logic in the AFS Client Service has been wrong
988 for sometime. It is based on two different assumptions.
989 First, the SMB client timeout is a fix value as was the case
990 with OS/2 Lan Manager. This assumption is incorrect. The
991 SMB timeout in Windows is a dynamic value computed based upon
992 a fixed minimum timeout to which is added time based upon the
993 size of the request and the performance characteristics of
994 the connection. Second, it is the responsibility of the
995 SMB Server to enforce the timeout requirements of the client.
996 This is untrue. The SMB Server cannot be expected to know
997 the requirements of the client. More importantly, if the
998 SMB server uses the SMB client timeout as a value to restrict
999 its behavior as an RX client, the performance characteristics
1000 of the local SMB session would be used to prematurely terminate
1001 WAN connections with significantly different performance
1004 The timeout logic has therefore been modified in the following
1006 . the Lan Manager Workstation (SMB) Session Timeout is used only
1007 as a basis for configuring the Connection Dead Timeout
1008 and Hard Dead Timeout values. The Connection Dead Timeout
1009 must be at least 15 seconds longer than the SMB Timeout
1010 and the Hard Dead Timeout must be at least double the
1011 Connection Dead Timeout.
1012 . New registry entries have been added to allow the Connection
1013 Dead Timeout and Hard Dead Timeout values independent of the
1014 Lan Manager Workstation Session Timeout
1015 . The test to enforce the SMB Client Timeout has been removed.
1017 One of the side-effects of removing the enforcement of the SMB
1018 Client Timeout is that regardless of whether or not the SMB client
1019 is available to receive the response (and how would the SMB server
1020 know) the RX protocol response can be used to update the AFS
1021 Client Service state for ready access by future SMB client
1024 This should be the end of the "Server paused or restarting messages"
1026 * Add support for arbitrary UNC paths to the pioctl() support.
1027 This enables the fs commands as well as the AFS Shell Extension
1028 to work correctly when UNC paths are being used.
1030 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1031 DNS if the cell configuration cannot be determined via CellServDB
1033 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1034 are ever set more than once at a time
1036 * Fix the management of lists of cm_cell_t structures when using
1037 DNS to lookup cell information. The previous code would fail to
1038 reuse the same cellID for a cell if DNS was used more than once
1039 for a given cell name. When the ttl expired, a single cm_cell_t
1040 could be inserted into the cm_allCellsp list more than once
1041 producing a loop. In addition, the vlServerp list belonging to
1042 the cell was not freed resulting in improper refCounting of the
1045 * Add DNS support to cm_IoctlNewCell() which previous only examined
1048 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1049 to properly garbage collect cm_server_t objects
1051 * Add numVCs variable to smb.c to track the number of smb_vc_t
1052 objects created and use it to initialize the vcID field which
1053 previously was set to 0 in all objects resulting in FindByID
1056 * Fixed DNS lookups to work consistently throughout the OpenAFS
1057 product instead of just from within the afsd_service.exe
1059 * Added a runtime check to ensure that AFS Client Service SMB
1060 Server is accepting connections before attempting to mount
1063 * Read IP addresses for volume servers out of the CellServDB
1064 file if gethostbyname() on the hostname fails.
1066 * Fix getcellconfig() to populate both the Hostnames as well
1067 as IP addresses when loading cell data via DNS
1069 * Increase the Connection Dead Time to 50 from 20 seconds
1070 Increase the Hard Dead Time to 120 from 40 seconds
1071 (matches the Unix values)
1073 * Fixed an assertion validating the number of allocated NCBs
1075 * Fixed the build environment to consistently build for
1076 Windows 2000 and above. (APPVER = 5.0)
1078 * Fixed rx_debug to properly validate the receipt in incoming
1079 data with select() and recvfrom(). Do not copy data out of
1080 the socket buffer unless success is indicated.
1083 * afsd_service.exe will now display a message box to the
1084 desktop when it terminates due to an IP Address Change.
1086 * installer no longer deletes AFS Server configuration data
1089 * installer generates a warning dialog if the RPC service
1090 is not properly configured
1092 * installer compressed with lzma instead of bzip2
1094 * afsd_service.exe shutdown crash solved once and for all
1096 * reference counting of smb_vc_t data structures improved
1098 * name space collision of smb_fid_t event objects corrected
1100 * the output of "fs memdump" is now written to
1101 %WINDIR%\TEMP\afsd_alloc.log
1103 * the file TaAfsApp_1033.dll is now properly installed allowing
1104 the User Manager to start
1106 * a new algorithm is used for computing filename pattern matches
1108 * afscreds.exe now accepts user names containing instance
1111 * Fix the Directory Name Lookup Cache to be case-sensitive.
1112 This is crucial in environments in which a Windows client
1113 is accessing a directory with more than one filename that
1114 differs only by case. If the directory contains "FOO"
1115 and "Foo". You want "DEL Foo" to delete the correct one.
1116 We still have a problem in that "DEL foo" will delete a
1117 random filename. This will be addressed in a future release.
1119 * Fix afscreds.exe -M option (renewMaps) to work when High
1120 Security mode is off. Also, remember to disable the ActiveMap
1121 flag in afsdsbmt.ini when a drive mapping is removed.
1123 * Updates to NSIS installer script. AFS Server configuration
1124 data will not be destroyed on un-install or re-install.
1125 Use a better compression algorithm.
1127 * afslogon.dll now uses KFW to obtain tokens when available
1129 * afslogon.dll when given an all uppercase username will
1130 attempt to authenticate with both the uppercase name
1131 and an all lowercase variation
1133 * DST modification removed. The fix appears to make things
1134 worse after a reboot of the machine.
1136 * fs.exe: added "cscpolicy" which is used to
1137 change client side caching policy for AFS shares
1139 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1140 [-documents] [-disable] [-help]
1142 * Several uninitialized variables have been initialized
1144 * It is now possible to obtain tokens using cross realm
1145 Kerberos within afscreds.exe:
1147 user: jaltman@ATHENA.MIT.EDU
1149 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1150 will will in turn be used to obtain afs@DEMENTIA.ORG.
1151 The resulting token will be stored with the display name
1152 jaltman@ATHENA.MIT.EDU@dementia.org
1154 * aklog.exe has been added to the client
1156 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1157 [[-p | -path] pathname]
1161 -d gives debugging information.
1162 krb_realm is the kerberos realm of a cell.
1163 pathname is the name of a directory to which you wish to authenticate.
1164 -noprdb means don't try to determine AFS ID.
1165 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1166 (default is Kerberos V)
1167 No commandline arguments means authenticate to the local cell.
1170 * All of the resource files have been restructured to adhere to
1171 a set of rules IBM implemented for loading string resources.
1172 These rules had either been forgotten or were not discovered
1173 by folks working on the OpenAFS sources. The end result was
1174 memory corruption. This is primary item which was preventing
1175 the AFS Server from working.
1177 * Increased the size of the maximum ticket size stored in a token
1178 from 344 bytes to 12,000. Increased the buffers used to convey
1179 messages between the pioctl() caller and the SMB Server from
1180 1000 bytes to 12,512. The code appeared to have been writing
1181 above the top of the stack by quite a few number of bytes.
1182 (The increased ticket size is necessary for the next item.)
1184 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1185 Instead the raw Kerberos 5 ticket is used in its entirety. This
1186 is extremely important as it allows us to use pure Kerberos 5 KDCs
1187 as the source of the AFS authentication. The use of up to 12,000 byte
1188 tickets will allow tickets produced by all versions of Microsoft
1189 Active Directory to be used.
1190 - create a user account.
1191 - designate it DES only
1193 - specify its UPN to be "afs@realm"
1194 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1196 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1197 is special when using long file names. (you must use "*.*" and not "*")
1198 Instead only enforce it when performing 8dot3 searches.
1200 * Fixed the DST problem with creation times being set one hour ahead
1202 * Fixed the problem when using \\afs\cell-alias. For example,
1203 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1204 for the alias name; instead simply expand the name. One of the
1205 symptoms of this problem was a loss of acquired tokens.
1207 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1208 of strings. (Only English strings provided.)
1210 * Fixed the installer to properly replace in use files.
1212 * Fixed the build system to cleanup generated component version files
1214 * The release build compiled with MSVC 6.0 compiler to avoid the
1215 afsd_service.exe shutdown crash. This does not solve the problem
1216 but simply avoids it for the time being.
1220 * fix afslogon.dll to not corrupt memory when High Security mode
1223 * fix afsd_service.exe to not attempt to restore the stack when
1224 an exception occurs. (not safe in multi-threaded programs)
1226 * fix uninstaller to properly remove the CRT and MFC DLLs
1228 * remove a Message Box from afscreds.exe when getcellconfig()
1229 fails on a kerberos realm which is not a cell
1231 The following is a list of changes to the OpenAFS for Window client
1234 * "fs setserverprefs" will leave afsd service deadlocked
1236 * "vos listaddrs" will core dump
1238 * installer sets the appropriate keys to support Integrated Logon
1240 * installer disables the "Find Lana by Name" functionality as it
1241 was causing headaches for many users
1243 * fix the intermittent crash of the power management thread when
1244 shutting down the AFS Client Service
1246 * optimizes the obtain drive mount list functionality which is
1247 executed every time the mount tab in afscreds.exe and afs_config.exe
1248 are refreshed. (this happens a lot)
1250 * fix the service shutdown logic. add the STOP_PENDING state
1251 and do not accept additional service events after we declare
1254 The following is a list of changes to the OpenAFS for Window client
1257 * flexelint was run against the source tree and hundreds (perhaps
1258 thousands) of corrections were applied to ensure prototypes
1259 were in use; types were used consistently; variables were
1260 initialized; unused variables were removed; etc.
1262 * A wide variety of instrumentation was added including the
1263 ability to produce a stack trace from within afsd_service.exe
1266 * Dynamic configuration of the RDRtimeout value based upon the
1267 LanMan Workstation Session Timeout
1269 * The mount root no longer needs to be called "/afs". This
1270 is now set by a registry value "MountRoot" within the key
1271 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1273 * The cell list is now only read out of afsdcell.ini when the
1274 file changes instead of each time a cell is resolved.
1276 * Thread synchronization was added to cm_server.c and ktc_nt.c
1278 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1279 calloc()/free(). The Global functions were needed on Windows 3.x
1280 but have caused a variety of problems on the Win32 platforms.
1281 Avoiding them is highly recommended by several Microsoft
1282 Knowledgebase articles
1284 * Support for Symbolic Links added to the AFS Shell Extension
1286 * Added a registry value "OverlayEnabled" to determine if
1287 Shell Extension Overlays should be enabled.
1288 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1290 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1291 separate trees for checked and free builds. Build system supports
1292 a custom directory src\WINNT\extra which can be used as a grafting
1293 location of organization specific additions to the build tree.
1295 * New installer built using NSIS 2.0.
1297 * Named all kernel objects in order to allow them to be monitored
1298 with tools such as SysInternals' ProcExp.exe.
1300 * Introduced new EventLog framework for AFSD
1302 * Introduced Power Management interface to AFSD for Standby and
1303 Hibernate modes to allow cache to be flushed prior to network
1306 * Utilize Win32 DNSQuery API instead of internal routines. This
1307 allows DNS SRV queries to be sent to all current domain name
1308 servers. Not just one specified in an INI file. DNS is now
1311 * "NetbiosName" registry value may be used to specify a fixed
1312 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1313 when the loopback adapter is in use. If you need to use the
1314 old notation with a loopback adapter installed specify a registry
1317 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1319 * Refactor all modules which depend on LAN Adapter and NetbiosName
1320 determination in a new library: lanahelper.lib. This allows for
1321 consistent behavior throughout the product.
1323 * Move the afsd.log and afsd_init.log files to the directory specified
1324 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1325 for services. Added the Date to the log entries.
1327 * New registry value "RxMaxMTU" used to limit the size of the RX
1328 packets sent by the AFS Client Service to the Server. In order
1329 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1330 size must be restricted to 1264 or smaller. The latest NSIS
1331 installer sets a value of 1260 by default.
1333 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1334 packets. This is not needed in order to work across the Cisco
1335 VPN but might be needed for other network environments. This
1336 value is not set by the NSIS installer.
1338 * New registry value "HideDotFiles" is used to apply the Hidden
1339 attribute to files whose names begin with a '.'. This value
1340 is set by the NSIS installer.
1342 * New registry value "MaxMpxRequests" allows the maximum number
1343 of multiplexed sessions to be configured at run time. This
1344 value is not set by the NSIS installer. The default value is
1347 * New registry value "MaxVCPerServer" allows the maxmimum number
1348 of VCs per server to be configured at run time. This value is
1349 not set by the NSIS installer. The default value is 100.
1351 * New registry value "AllSubmount" allows the "all" submount to
1352 be disabled by setting its value to 0x00.
1354 * Allow cells names to be valid mount points
1355 \\<netbiosName>\<cellname>
1357 * Store the active state of drive mappings in order for afscreds.exe
1358 to restore them upon startup
1360 * Add exception handling to generate a Stack Trace to the afsd_init.log
1361 file if one happens to occur.
1363 * Add lots of logging to help detect the cause of invalid SMB packets
1365 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1366 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1367 renewal of expiring tokens as long as afscreds.exe is running.
1369 * New afscreds.exe command line options:
1371 -M = renew drive maps
1372 -N = ip address change detection
1375 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1376 determines whether or not MIT Kerberos for Windows should be used
1377 to obtain tokens via Kerberos 5 tickets.
1379 * New registry value "AfscredsShortcutParams" in
1380 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1381 determines the command line parameters to be specified when "fixing"
1382 the AFS Shortcut in the user's startup folder.
1384 * The "ShowTrayIcon" registry value has been moved from
1385 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1386 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1388 * The <cell name> registry values used to store the token expiration
1389 reminders have been moved from
1390 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1391 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1393 * Obtain the Logon User Name from the Explorer key when available
1395 * new text document doc\txt\winnotes\registry.txt lists all registry
1396 values used by OpenAFS (excluding the AFS Server)
1398 * BUG: rx_securityClass objects were not properly reference
1399 counted and were never freed.
1401 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1402 would be generated. The existence of a server does not imply
1403 that it is not down. If all of the servers for a cell are down
1404 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1407 * BUG: the directory name lookup cache failed to free the entries
1408 in the cache when the name cache entries cycled. The entries
1409 in the cache would become dereferenced without being freed.
1411 * BUG: fs setserverprefs could be executed without Administrator
1414 * BUG: the number of allocated NCB objects (100) exceeded the number
1415 which could actually be waited upon by the kernel (64). Any objects
1416 which were utilized above the limit could never have event completions
1419 * BUG: smb_username_t objects were not being reference counted and
1420 were not properly freed.
1422 * BUG: smb_tid_t objects could under unusual circumstances be freed
1423 before they were no longer referenced.
1425 * BUG: smb_fid_t object pointer were frequently used even when
1426 their value could be NULL. They were not properly released and
1427 therefore they were never freed.
1429 * BUG: smb_packet_t data structures were not completely initialized
1432 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1433 Denied" because that causes the Explorer Shell to try again until
1434 access is obtained. Instead return "Remote Resources" which allows
1435 the shell to move on and treat the error as transient.
1437 * BUG: when initializing the NCBreturns structure, separate Event objects
1438 were created for each NCB although a single Event object was supposed
1439 to be shared by all.
1441 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1444 * BUG: smb_tran2Packet_t objects were not being properly referenced
1447 * BUG: directory path creation did not handle the case of multiple
1448 directories requiring creation in one attempt
1450 * BUG: SMB requests which required an Extended Response were ignored.
1451 This prevented some files from being written to AFS volumes.
1453 * BUG: character strings were being freed even after they were
1454 inserted into in use data structures
1456 * BUG: inconsistent usernames were used when High Security mode was
1457 enabled. (there is still much to do in this area)
1459 * BUG: pioctl() calls which require out of band RPC operations were
1460 susceptible to race conditions when performed by multiple processes
1462 * BUG: memory allocation and deallocation crossed instances of the
1463 C Runtime Library producing memory leakage and corruption in
1464 afscreds and the client configurator.
