2 * Update the NSIS install scripts to use 2.07. This release adds
3 recommended installation categories: AFS Client, AFS Administrator,
4 AFS Server, AFS Development Kit. Each category includes a different
5 default subset of the OpenAFS components.
7 The OpenAFS logo is now associated with the NSIS uninstall entry
8 in the Add/Remove Programs control panel.
10 * The user name associated with AFS tokens when obtained with
11 integrated login, the afs systray tool, or aklog will always
12 include the full Kerberos 5 user principal name regardless of
13 whether or not the cell is local to the realm.
15 * Eric William's IFS redirector has been checked onto the CVS head.
16 This code is experimental at the current time and is not being
17 incorporated into the 1-4 branch releases. Instructions for
18 building from sources are found in the top-level README-NT file.
20 * Modify integrated login so that it does not enter an infinite
21 loop if the service is not set to auto start.
23 * Added asetkey.exe used to set a Kerberos 5 key for use by the
26 * Added uninstall.exe to Wix installation
28 * More modifications to algorithms used to wake sleeping threads.
32 * Changes to the algorithms used to wake threads when they are
33 put to sleep because of conflicts over buffer operations.
36 * The OpenAFS integrated logon obtains Kerberos 5 tickets as part of
37 the process of producing AFS tokens. The tokens are stored within
38 the AFS Client Service but the Kerberos 5 tickets have been discarded.
39 New functionality has been added to temporarily copy the tickets to
40 a file ccache during the short window between the NPLogonNotify and
41 WinLogon Logon Event. The Logon Event handler starts a process as
42 user, afscpcc.exe, that copies the tickets into the default ccache.
43 The file ccache is then destroyed by the event handler.
45 * During synchronization operations on stat cache entries, if threads
46 are forced to sleep it was possible that the threads would not be
47 woken under heavy load.
49 * Enforce the delete on close flag specified by the NTCreateX()
52 * A race condition in the rx library was fixed that resulted in
53 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
54 was cleared when threads were still waiting to use the
55 connection. Also, fixed a potential case in which the
56 connection could be destroyed while threads were waiting to use it.
58 * The DNLC freelist has been seen to become corrupted with still
59 active entries being stored on the freelist. Changes were made
60 to perform a better job of cleaning entries before placing them
61 onto the freelist; marking them with the correct magic value when
62 purging the list; and allowing the list to be purged on startup
63 if the cache validation fails.
65 * Windows Crash Reporting does not get triggered for afsd_service.exe
66 because it provides its own top level exception handler. This patch
67 places an explicit call to ReportCrash() on platforms which support
70 If you configure Crash Reporting via AD Policy to capture crash
71 reports within the domain, then you will receive this output.
73 * Generate MiniDumps independent of the Windows Crash Reporting.
75 (a) If an exception occurs,a minidump will be generated at the path
76 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
77 can be set to any other type via use of the
80 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
82 (b) MiniDumps can be generated at any time using the "fs minidump"
83 command. This allows you to generate a minidump without
84 stopping the process or even requiring the use of a debugger
87 * an RX connection which reports bad ticket now treats it the same way
88 the expired ticket is treated. The ticket is removed from the
89 connection and a new anonymous connection is established.
91 * fs memdump now requires that the caller be in the AFS Client Admins
94 * additional debugging information is provided in cm_Analyze when the
95 error code is ignored.
97 * Fix a regression introduced into the pioctl() client code which
98 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
99 MIT KFW is not installed. (1.3.82a)
101 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
104 * Fix a race condition in cm_EndCallbackGrantingCall() that
105 could leave 'nrevp' pointing to freed memory. In the process,
106 optimize the processing to ensure that the applications monitoring
107 the status of the stat cache entry are only notified at most
110 * Conditionalize access to the Explorer Shell AFS->Mount Point
111 ->Remove menu item. Disable the item if the selected item(s)
112 are not mount points.
114 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
115 Local Storage. This eliminates thread contention on the
116 global RX free packet queue. This should improve performance
117 on multi-CPU systems.
119 * Fix the IP address filtering code to properly load/unload
120 the IPHelper DLL so that Windows XP/2003 and beyond systems
121 do not have to manually probe the registry.
123 * CleanupACLEnt() was not being called consistently with
124 the cm_scache_t object referred to by the back pointer
125 mutex locked. This could in very rare conditions lead to
126 an invalid memory access.
128 * Added a script command to the msi installer "afs_replace"
129 which can be used to replace one version of OpenAFS with
130 another without requiring an uninstall and reinstall if
131 the installed msi is no longer in its original location.
133 * Apparently the problem with multi-domain forests with cross-
134 realm trusts to non-Windows realms was not entirely solved.
135 The authentication to the AFS SMB service failed because
136 the wrong name was being used. Using ASU as an example,
137 the authentication was being performed with the name
138 "QAAD\user" (an account in the forest root) and not
139 "user@ASU.EDU (the MIT Kerberos principal used to login with)
141 The solution was to add an additional dependency on KFW
142 in order or to be able to easily obtain the client principal
143 name stored in the MSLSA ccache TGT. This information is
144 used in two locations:
146 - the pioctl() function
148 - a new WinLogon Event Handler for the "logon" event.
150 The pioctl function will now be able to use the correct
151 name when calling WNetAddConnection2() and the "logon"
152 event handler will now be able to call WNetAddConnection2().
153 The hope is that the "logon" event handler will be called
154 before the profile is loaded but I have not guarrantee
158 * Fixed a locking error in cm_TryBulkStat() which had the
159 potential of deadlocking the system for the length of time
160 it takes to perform a bulk status fetch operation.
162 * Replaced time conversion code (UnixTime <-> FILETIME) to
163 be completely arithmetic instead of relying on a bizarre
164 algorithm involving a variety of C RTL time functions.
165 This has the side effect that UnixTime and FILETIME which
166 are both stored in UTC are interpretted as UTC throughout
167 the year. Windows will apply the same localization to AFS
168 as it does to NTFS. Applications which rely on the ability
169 to sync files between the two file systems will no longer
170 see the timestamps of files in AFS change an hour relative
171 to the files stored in NTFS or Windows based backup devices.
173 * Fixed a invalid memory access under a bizarre circumstance.
174 Windows will allow a physical mass media device to be
175 installed via Plug N Play to the system and will assign it
176 the lowest available drive letter. This is true even if the
177 drive letter is currently assigned in the user session to
178 a network device via NET USE (or its equivalent.) When this
179 happens, queries sent to the CIFS server will contain invalid
180 data. This invalid data was not being caught by the AFS
181 Client Service and was resulting in a crash when Freelance
184 * Fixed a reference count error when registering callbacks
185 on a stat cache object if the callback was already registered
187 * Add a case to cm_Analyze() in order to handle the case where
188 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
189 the server list for the volume is empty. In this case, force
190 an update of the volume info and retry.
192 * Insert a missing cm_EndCallbackGrantingCall() which could
193 result in threads waiting for a callback to complete to never
196 * In the persistent cache, there is a maximum number of volume
197 entries. Allow volume entries to be reused if the maximum
198 number have been allocated and their reference count is zero.
200 * If we already have a dead virtual connection object, don't
201 ignore the fact that additional dead vc objects must be taken
204 * Removed a deadlock condition introduced in the summer of 2004.
205 Do not hold mx locks around calls to RX functions including
206 rx_NewCall(). That is what reference counts on the rx_connection
209 * Fixed an initialization error in afslogon.dll which could
210 result in random behavior including a failure to terminate
211 the NPLogon function. (1.3.80b)
213 * Fixed an error preventing the use of SMB authentication
214 on Windows 2000. (1.3.80a)
217 * Updated CellServDB to Public CellServDB 16 Mar 2005
219 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
220 misinterpretted as "csail.mit.edu" when the resolver
221 is configured to append ".mit.edu" to failed DNS queries.
223 * Fixed another case in which the client would replace connections
224 to the host when it was not necessary. In this case the
225 situation would occur if cryptall was on and the connections
226 were unauthenticated due to lack of an appropriate token.
228 * OpenAFS for Windows has failed to work at sites which are
229 utilizing a cross-realm trust between an MIT/Heimdal realm
230 and a multi-domain Windows forest when the workstation being
231 accessed is not located in the root domain. This is caused
232 by a bug in the workstation which was triggered after the
233 introduction of Windows 2003 Server. When the bug is triggered,
234 the workstation attempts to authenticate users to afsd_service.exe
235 by contacting the Domain Controller instead of using the
236 LSA loopback authentication mechanism.
238 One of the reasons this bug occurs is because the workstation
239 does not have a reliable way of knowing that the service whose
240 netbios name is "AFS" is located on the workstation. This will
241 be fixed starting in Longhorn Beta 1 by Microsoft. The
242 "BackConnectionHostNames" registry value will be used to
243 indicate that the authentications to that service name should
244 be performed using the loopback authentication mechanism.
246 In the meantime, when Logon Caching is enabled, we can force
247 afsd_service.exe to authenticate using the logon cache before
248 contacting the Domain Controller. This will work with both
249 password and smart card based logons.
251 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
252 flag should not be cleared if a volume's server reference is
253 marked as "offline". In the case where all of the volume's
254 servers are either "down" or the volumes are "offline", we want
255 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
256 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
257 should never occur in practice.
259 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
260 5 seconds, clear the server down and volume busy flags, and
261 then force an update from the VLDB. This allows the client to
262 update the location of a volume if the reason for it being
263 marked offline is because it is being moved. Calls to
264 cm_ConnByMServers() will be retried either until success or
265 the RDRtimeout period is reached.
267 * Correct the Power Management code behavior in response to
268 Standby, Suspend, and Shutdown events. Instead of flushing the
269 buffers associated with the mounted SMB submounts, simply write
270 all buffers which are marked dirty.
272 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
273 provides a list of cells other than the default cell for which
274 tokens should be obtained using the default Kerberos principal.
275 This functionality is logon domain specific and is only available
276 when using KFW for authentication.
278 * Fixed FindNext Invalid Handle error caused by over agressive
279 attempts at garbage collecting dirSearch entries when the
280 dirSearch ID wraps from the maximum value to 1.
282 * Add support for registry defined server preferences for VLDB and
283 File servers. See registry.txt for details.
285 * Increased default cache size to 96MB and default number of cache
288 * Fixed refCount leaks related to directory lookups and pioctl calls.
290 * Callbacks revoked during a race condition with an attempt to
291 obtain the same callback no longer result in an inaccessible
294 * New command line tool:
296 afsdacl : Set or reset the DACL to allow starting or stopping
297 the afsd service by any ordinary user.
299 Usage : afsdacl [-set | -reset] [-show]
301 -reset : Reset the DACL
302 -show : Show current DACL (SDSF)
304 * IP addresses are no longer queried once at startup. Instead IP
305 addresses are obtained as needed. Loopback adapter addresses are
306 no longer published to the server.
308 * Pay attention to the MIT KFW registry configuration for automatic
309 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
311 * Fix (once again) case-sensitive comparisons which was apparently
314 * Activate support for vos listvol -format
316 * Population of the "AFS Client Admins" group failed on non-English
317 versions of Windows because the name of the "Administrators" group
318 is localized. Now we lookup the name of the group by using the
319 Administrators Group Alias Relative ID.
321 * Multiple cell token acquisition within afscreds.exe was broken in the
322 case of Kerberos 5 cross realm authentication. Instead of contacting
323 the KDC associated with the cell's realm, afscreds would obtain a
324 token from the KDC of the user's realm. This would result in
325 "invalid kvno errors" while authenticating to the AFS servers.
326 Unauthenticated access would work. The symptoms would vary based upon
327 whether or not the VLDB servers had been contacted using unauthenticated
328 connections prior to the user obtaining tokens.
330 * The list of ACL entries was becoming corrupted. It appears as if
331 an ACL when it expires was not being appropriately cleaned up. In
332 fact, it was left in the list of ACLs associated with the scache
335 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
336 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
337 and "amd64_win64" for amd 64-bit processors.
339 * When executing executables, Windows provides a mechanisms by which
340 the normal search for DLLs can be bypassed. If a file foo.exe is
341 being executed and there exists a file or directory "foo.exe.local"
342 (the contents are ignored if a file), then Windows will search for
343 DLLs first in the "foo.exe.local" directory and second in the
344 directory in which the "foo.exe" file is located.
346 Previous releases of OAFW would improperly return
347 STATUS_NOT_A_DIRECTORY instead of the expected
348 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
349 to terminate the search for the DLL causing the execution of the
352 * Rework the reference counting of smb_vc_t objects. The references
353 stored in the waiting locks were not counted. This could result in
354 an assertion if the reference count drops to zero.
356 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
357 when running in freelance mode.
359 * Added support for persistent caching of file contents, stat entries,
360 volume data, cell data, and name lookup data. When the registry
361 value, "NonPersistentCaching", is not defined or set to 0 the file
362 specified by "CachePath" becomes a persistent cache file. The
363 size of the cache file is computed at run time. It has a maximum
364 size of approximately 1.2GB. The contents of the file will be
365 validated according to the rules specified by the "ValidateCache"
368 * Added support for UUIDs. UUIDs are kept for as long as the
369 cache file is intact.
371 * Added cmdebug.exe and support cache manager debugging callback
372 interfaces in afsd_service.exe.
374 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
375 [-addrs] [-cache] [-help]
376 Where: -long print all info
377 -addrs print only host interfaces
378 -cache print only cache configuration
380 * Symlinks to \\AFS\[all\]... will now be treated the same as
381 symlinks to /afs/.... However, please use /afs/... as otherwise
382 the symlinks won't work on Unix.
384 * Correct a problem with local CellID allocation for cells whose
385 server list is obtained via DNS instead of a CellServDB file. If
386 the DNS information expires the CellID assigned to the entry will
387 be changed. This causes all of the cm_scache_t objects which refer
388 to the old cellID number to become useless. Attempts to access
389 files or directories with cm_scache_t objects using the old cellID
390 will fail since the server list cannot be obtained.
392 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
393 be triggered if the volume referenced by the cm_scache_t object is
396 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
397 in addition to SERVICE_ACCEPT_STOP.
399 * Move RPC shutdown until after the SMB and RX shutdown procedures
400 complete. Block until RPC shutdown is complete.
402 * Modify afslogon.dll (integrated logon) to wait for service if its
403 state is START_PENDING. If the timeout period occurs, reset to
404 the retry interval and not the sleep interval.
406 * When renewing the server list for a cell obtained via DNS AFSDB
407 records, the cm_cell_t entry must be removed from the list of all
408 cells. Otherwise, the list of cells will be corrupted.
410 * In the dcache and scache modules, use the cm_scache_t dataVersion
411 instead of the cm_fakeDirVersion.
413 * Synchronize fs.c with the unix version.
415 * The variable used to determine whether a file or virtual memory
416 mapped cache is used was not properly initialized to a default
417 value. If the registry setting "NonPersistentCaching" was not
418 set, the choice would be random. Properly initialized to be
421 * The memory mapped view was never unmapped before closing the file
422 at service shutdown. This is now properly cleaned up.
424 * Default location of Cache file is now %TEMP%\AFSCache
428 * A bug affecting new installations of 1.3.75/76 would result in
429 the creating of incorrect mountpoints in the freelance root.afs
430 volume for the default cell.
432 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
433 of "root.cell", you have been affected by the bug. To correct the
434 problem, execute the following commands:
436 fs rmmount \\afs\all\<cellname>
437 fs rmmount \\afs\all\.<cellname>
439 fs mkmount \\afs\all\<cellname> root.cell <cellname>
440 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
444 * A bug has been fixed in the auto-generation of Freelance root.afs
445 symlinks which produced random entries in the \\AFS\all directory.
447 * Support has been added for multi-homed servers
450 * Added a new registry value, "StoreAnsiFilenames", which can be used
451 to force the use of ANSI character sets instead of OEM Code Pages.
452 This feature is useful when users require the ability to create
453 filenames with 8-bit characters and need to access the files from
454 both Latin-1 based Unix systems as well as from Windows.
456 Activation of this feature will prevent access to files stored with
457 8-bit OEM characters.
459 * Shutdown all SMB threads in a synchronized manner when stopping the
462 * There is currently a maximum cache size of 1.3GB. The limit is imposed
463 by the largest contiguous block of unused memory within the 2GB process
464 space which can be assigned to the memory mapped file. Unfortunately,
465 when the executable digital signature verification code is activated
466 Windows sees fit to further segment the process memory which in turn
467 reduces the size of the maximum cache file to less then 800MB. If
468 larger cache sizes are desired, a new registry value should be set:
470 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
472 Setting this value will disable the runtime verification of digital
473 signatures on afsd_service.exe and the afs dlls which it loads. It
474 will not disable the the version number check on those same files.
475 The signature verification is not a security messure and is only meant
476 to enhance the ability to afsd_service.exe to detect potential
477 destablizing mixtures of DLLs from incompatible distributions.
479 Added code to auto-disable the signature verification check if
480 the desired cache size is greater then 700MB.
482 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
483 used to verify the validity of the afsd_service.exe binary
484 as well as each of the AFS DLLs loaded by the service. Not only
485 must the digital signature be valid but the signatures of the
486 DLL must be signed by the same entity as the service.
488 * Implement new functions: cm_freelanceMountPointExists and
489 cm_freelanceSymlinkExists. Use them along with other validity
490 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
491 ensure that name collisions do not occur and that empty strings
492 are not valid file names.
494 A symlink may not have a name which would resolve to a valid
495 cell name. Doing so would prevent access to the cell.
497 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
498 re-initialization code. The reference counts of the fake root.afs
499 volume scache object(s) would become invalid when the mount point
500 or symlink lists were altered.
502 * Add registry entries to provide mappings from the afsdsbmt.ini
503 to the new locations for applications which count on the use
504 of the old Profile file APIs. These apps are likely to fail
505 if the user does not have administrator privileges and the
506 registry is locked down.
508 * The afs_config.exe submounts dialog had two errors.
509 First, attempts to remove entries failed because the registry
510 key was being opened without KEY_WRITE privileges.
511 Second, when editing a submount entry, changing the name
512 would add a new key and leave the original one in place.
513 Now the original submount will be removed if its name is
516 * In recent months there have been several incidents in which
517 users have experienced problems starting or accessing
518 afsd_service.exe and after significant effort has been spent
519 it has turned out that they have two versions of AFS on the
520 machine or an inconsistent set of DLLs.
522 Code has now been added to afsd_service.exe which will walk
523 the list of modules loaded by afsd_service.exe and validate
524 that the version of the AFS DLLs matches the version of the
525 afsd_service.exe executable. If they do not match the service
528 * When Freelance mode is enabled and there is no registry
529 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
530 will attempt to import the afs_freelance.ini file contents.
531 If the file does not exist, it was creating a dummy file
532 with a r/o and r/w entry for the default cell and then
533 importing those values.
535 This process has been changed. The temporary file is no
536 longer created. Also, both the OpenAFS Client install
537 directory as well as %WINDIR% are checked for previous
538 afs_freelance.ini files.
540 * Added support for VL_GetEntryByNameN(). Still need to add
541 support for VL_GetEntryByNameU() for multi-homed support.
543 * Fix a deadlock situation in afscreds.exe when canceling an
544 auto-generated Obtain Tokens dialog
547 * Fix the locking of objects during Directory Searches in the
548 SMB/CIFS server. The failure to properly lock the reference
549 counts was resulting in the premature freeing of smb_dirSearch_t
550 objects while they were still in use by the SMB/CIFS client.
551 This does not solve the "Invalid Handle" problem.
553 * Fix Find Cell By Name pioctl call to return a valid cell
554 name for the Freelance fake root.afs volume.
555 "Freelance.Local.Root".
557 * Fix the Explorer Shell Extension Symlinks->Add operation.
558 The dialog template was missing and the link destination
559 string was too short.
561 * Add support for symlinks to Freelance root.afs volume
562 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
563 <number> = "<linkname>:<relative-path>."
564 Use symlink.exe to create, list, or remove
566 * Remove the fallback to the use of KFW's KRB4 library when obtaining
567 tokens. We never obtain KRB4 tickets.
569 * Fix AFS Client Configuration Control Panel to support new SysName
572 * Fix a bug in afsd_service.exe which could result in the SysName
573 not being read from the registry.
576 * Add code to block the issuance of AFS tokens by aklog.exe or
577 afscreds.exe when the Kerberos 5 principal name contains a dot.
579 * Modify the IsAdmin() function to always treat the local SYSTEM
580 account as an AFS client administrator. Affects fs.exe and
583 * Modify the internal handling of Quota Exceeded errors
585 * Upgrade all reference count fields in the Windows cache manager
586 and the osi library to use unsigned long instead of signed short.
587 A similar fix has been applied to the afs rpc (rx) library.
589 * fix the Windows cache manager to prevent it from replacing the
590 rx_connection object associated with the cm_conn_t object on each
591 and every operation if "fs crypt" was set. This explains the
592 dramatic performance difference when crypt is used vs clear.
593 The problem: 'cryptall', a boolean flag indicating whether or not
594 "fs crypt" is set, was being compared to the rx_connection
595 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
596 1 != 2 and therefore the rx_connection was always destroyed
597 and replaced on each and every operation.
599 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
600 It is not safe for the cm_conn_t object to not be locked because
601 rx_DestroyConnection might be called from another thread if:
602 - the user's tokens have changed or expired
603 - the crypt mode has changed
605 This fix appears to have also taken care of the problems associated
606 with Overlapped Writes resulting in Delayed Write errors.
608 * fix NSIS installer's AdminGroup.exe to properly create and
609 remove groups when given -create or -remove. The string comparison
612 * fs sysname now accepts a list of sysname values
614 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
615 DWORD which when set to a non-zero value will cause error message
616 text to be output to stderr from the pioctl() routine. Useful in
617 debugging failures of fs.exe, tokens.exe, etc.
619 * added a test to the power management code to only perform a
620 flush operation if there is at least one network adapter which
621 is not a loopback adapter.
623 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
624 "EnableKFW". This value will not be read if the key
625 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
626 value under that key does not.
628 * provide mechanisms to force the use of krb524d for Kerberos 5
629 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
630 there is a new registry value "Use524" and for aklog.exe a new
631 command line parameter "-m".
633 * Fix the pattern matching algorithm to properly match patterns
636 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
637 which is used by both the original function and the new
638 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
639 creation of HardLinks in addition to Renaming. smb_Link()
640 is a new function which creates HardLinks via cm_Link().
641 cm_Link() is a new vnodeops function which creates links
644 smb_ReceiveNTRename() does not support the File Copy and
645 Move Cluster Information operations described in its interface.
646 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
648 * When opening files via symlinks, we should follow the symlinks
649 until we reach the actual file stat cache entry. The stat cache
650 entry of the file should then be stored in the FID instead of
651 stat scache entry of the symlink.
653 * return bad operation errors for all unimplemented functions
654 even if we do not know the functions exist.
656 * Log bad packets and unknown operation packets to the trace log
658 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
661 * Update list of known CIFS operations to include all those listed
662 in CIFS-TR-1p00_FINAL.pdf.
664 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
665 to support the REG_EXPAND_SZ type.
668 * A new Windows authorization group "AFS Client Admins" is now
669 created and populated with the members of the "Administrators"
670 group. The group is used to determine which accounts on the
671 machine may be used to modify the AFS Client Configuration via
672 the UI and command line tools. afs_config.exe, fs.exe,
674 * Modify the WinLogon Logoff Event Handler to query NT4 domain
675 controllers for the remote profile path if Active Directory
676 services are not available.
678 * Fix aklog.exe to not add the AFS ID to the username
680 * PTS registration of new users to foreign cells has been added to
683 * The cm_Daemon thread is used to perform checks for
684 down servers, up servers, volumes, callback expirations,
685 lock maintenance and token expiration. Due to a gaff in
686 larger integer division the thread never performed any
687 work. Instead the current time computation would always
688 be less then the trigger times. This had an adverse affect
689 on the client's ability to maintain communication with servers,
690 keep volumes up to date, and flush user tokens and acls
691 when they have expired. This was broken when the 1.3 branch
692 was modified to support VC7 which no longer included
695 * An initialization problem with the Freelance code was
696 detected while fixing the callbackRequest. The cm_rootSCachep
697 object is obtained during afsd_InitDaemons() but the callback
698 information is incomplete. The callback information will not
699 be obtained until cm_MergeStatus is called from within
700 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
701 test for the conditions under which the callback information
704 * Reports have been filed indicating that callbacks were
705 being lost. An examination of the code indicated that the
706 cm_server_t objects were not being properly reference
707 counted by the cm_scache_t and cm_callbackRequest_t objects.
708 In particular, the cm_server_t objects may have been freed
709 from beneath the cm_conn_t objects.
711 All of the reference counting is now done via the functions:
716 this improves the ability to track the referrals.
718 Each cm_BeginCallbackGranting Call now allocates a reference
719 to the cm_server_t. The cm_EndCallbackGrantingCall either
720 frees the reference or transfers it to the cm_scache_t
721 cbServerp field. These are then appropriately tracked
722 through the cm_Analyze call.
724 * Ensure that the dnlc hash table is the same size as the
725 dir name hash table (as per original author's note).
726 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
727 for compatibility with 64-bit systems.
729 * fix smb_ApplyV3DirListPatches to properly apply the hidden
730 attribute to dotfiles when the infoLevel < 0x101 and
731 cm_SyncOp has failed.
733 * Fix the Freelance registry initialization code. There
734 was a possibility that some systems could end up with
735 garbage in the registry during a clean install.
738 * file and directory names beginning with "." will now be given the
739 hidden attribute when the volume access is anonymous. this matches
740 the behavior when the volume access is via an authenticated user.
742 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
743 key. When a change occurs mark the root.afs data as invalid and
744 for it to be reloaded on the next access. This allows administrators
745 to modify the mount point list without restarting the service.
747 The freelance client used to provide a fake modification time for
748 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
749 Added code to extract the last modification time of the Freelance
750 registry key and use that instead. The time now represents the
751 most recent mount point change.
753 * PTS registration of new users to foreign cells has been added to
756 * Additional Cache Control and Credential Manager options have been
757 added to the WiX installer. See deployment guide for details.
759 * The CachePath setting is now optionally a REG_EXPAND_SZ type
761 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
764 * The loopback installation code may have had a problem updating the
765 %ETC%\HOSTS file which could have resulted in a premature failure.
766 Work around code has been added for the case where the file cannot
769 * The default max chunksize was increased from 15 (32K) to 17 (128K)
770 because Windows sends 64K blocks when using overlapped writes.
772 * The default number of server threads was increased from 4 to 25 to
773 better handle overlapped writes.
775 * The "AfscredsShortcutParams" registry value was not being properly
776 loaded by afscreds.exe. Therefore, the default value was always being
777 used instead of the value set by the installer.
779 * Windows XP provides downgrade attack detection to prevent an attacker
780 from being able to force the use of NTLM simply by disrupting
781 communication with the KDC. This attack cannot exist between the
782 Windows CIFS client and the AFS Client Service. Therefore, when a
783 downgrade has been detected the afs pioctl library will force the
784 establishment of a new CIFS connection using NTLM.
786 * A locking error was discovered surrounding all references to volume
787 server lists within the cm_cell.c source file.
789 * The logged into Windows username was incorrect on Terminal Server
792 * A new registry value "NonPersistentCaching" was added to the service
793 parameters key. When set to a non-zero value, the afs cache is stored
794 in the Windows paging file. There are two limitations to choosing
796 1. when persistent caching is implemented it won't work with
797 this flag set since there will be nothing to persist.
798 2. with this flag set the initial paging allocation cannot be
799 changed while the service is running
801 * An initialization bug was discovered in aklog.exe which affected users
802 who have a domain name for their afs servers which could not be mapped
806 * afs_config.exe now validates cell names against DNS in addition
807 to the CellServDB file.
809 * In order to allow the freelance client to connect to a volume with ID
810 equal to 1 on the default cell we changed the fake root.afs volume ID
811 once again. This time we choose 0xFFFFFFFF. In addition, we change
812 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
813 It will now be impossible for a volume ID to match that of another
814 cell unless the client is connected to 0xFFFFFFFD cells. That should
815 be enough room for growth.
817 * Fix "fs mkmount" command to work with UNC paths and when
818 started from non-AFS drives. It is now possible to create a mount
819 point in the freelance fake root.afs volume with the command
821 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
825 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
826 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
828 * The algorithm used to re-attempt access to the servers associated with
829 a volume has been altered to properly address the case in which all
830 servers have been marked down. The previous algorithm did not reset
831 the server's down flags so the servers were never actually retried.
832 This caused a problem with active volumes if the network connectivity
833 was lost as could be the case with a network cable removal, wireless
834 drop, or laptop hibernation. With the fix volume access is restored
835 almost instantenously when network connectivity becomes available.
837 * Support for SMB/CIFS browsing has been added to the AFS Client Service
838 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
839 listing of AFS submounts and freelance mount points. Support for
840 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
841 significantly enhances the behavior of AFS volumes within the Explorer
842 Shell. For instance, "AFS" now shows up as server in the Explorer
843 with each submount or freelance mount point visible as a share.
844 The right click menu in each folder now works with full functionality
845 on a consistent basis.
847 * The network provider can be configured to have different behavior
848 depending on the domain that the user logs into. These settings are
849 only relevant when using integrated login. A domain refers to an
850 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
851 local machine (i.e. local account logins). The domain name that is
852 used for selecting the domain would be the domain that is passed into
853 the NPLogonNotify function of the network provider. (see registry.txt
856 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
857 "Authentication Cell" which may be used to specify a default
858 authentication cell for afscreds.exe which is different from
859 the default cell for the AFS Client Service daemon.
861 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
862 afslogon.dll moved to %WINDIR%\System32\.
863 New registry entries added to register the dll for Winlogon events.
865 The logoff event will now force a call to ktc_ForgetAllTokens()
866 using the context of the user being logged off as long as the
867 user's profile is not loaded from within AFS. If the profile
868 was loaded from AFS we can't release the tokens since the Logoff
869 event is triggered prior to the profile being written back to
870 the its source location. This is now performed in an XP SP2
873 * Windows XP SP2 Internet Connection Firewall interoperability
876 * The %WINDIR%\afsdsbmt.ini contains four sections:
877 Submounts, Drive Mappings, Active Maps and CSC Policies.
878 The Submounts and CSC policies are now stored in the registry under
879 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
880 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
881 The Drive Mappings and Active Maps are stored in the registry under
882 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
883 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
885 There is no automatic migration of this data as it would be impossible
886 to consistently migrate data to user profiles which may not be active
887 when the machine is updated.
889 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
890 fake root.afs volume. For the same reasons as for the cellservdb file,
891 this information should not be in %WINDIR%. This information is now
892 kept under the registry key
893 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
895 The data from the afs_freelance.ini file will be automatically
896 migrated to the registry on first execution of afsd_service.exe
898 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
899 troublesome for several reasons. One, it is confusing for those who
900 expect the file to be named "CellServDB" instead of "afsdcell.ini".
901 Two, this file is not a Windows Profile formatted file. Three,
902 applications should not be reading or writing to %WINDIR%. It causes
903 problems for Windows Terminal Server.
905 The new location of CellServDB will be the OpenAFS Client install
906 directory which is by default C:\Program Files\OpenAFS\Client and can
907 be determined by querying the registry for
908 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
910 The existing afsdcell.ini will be migrated by the NSIS installer.
911 The Wix installer must still be updated to do the same.
913 * Change NSIS installer to use DNS by default; to remove Integrated Logon
914 High Security mode; and to add Terminal Services compatibility registry
915 entries to allow the OpenAFS tools to find the afsdcell.ini and other
916 configuration files in %WINDIR%.
918 * Add support for authenticated SMB connections. This will remove
919 the need for high security mode in most situations. Both NTLM
920 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
921 only NTLM can be used even though Kerberos is now supported. The
922 reason is that it is not possible to construct a service principal
923 which is unique to each individual machine.
925 SMB Extended Auth does not work on XP SP2 unless one of two registry
926 modifications are made:
928 (1) To disable the check for matching host names on loopback connections
929 set this key. This does not require a reboot:
931 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
932 "DisableLoopbackCheck"=dword:00000001
934 (2) To add the AFS SMB/CIFS service name to an approved list. This
935 does require a reboot:
937 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
938 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
940 afsd_service.exe will automatically add the current Netbios Name
941 to the BackConnectionHostNames list and then temporarily disable
942 the loopback check for one cycle of startup/shutdown of the service.
943 We assume most folks do not start/stop without a reboot so this
944 will be adequate in most cases.
946 * Fix security hole in afslogon.dll which allowed passwords to be
947 sent in clear text to the KDC in a misformed principal name.
949 * Fix cm_GetCell() to properly handle expired dns entries
952 * If Freelance mode is active and the afs_freelance.ini
953 file does not exist, do not create an empty file.
954 Instead create a file containing ro and rw mountpoints
955 to the default cell using the standard conventions.
957 * Modify the Freelance support to handle the ability
958 to create rw mount points in the fake root.afs volume.
960 * Changed the RPC mechanism used for token setting from
961 named pipes to local. Use of named pipes can be restored
962 by setting the environment variable AFS_RPC_PROTSEQ to
965 Named pipes were required when a Windows 9x system was
966 using a NT system in gateway mode which is incompatible
967 with our use of local loopback adapters.
969 * In afscreds.exe, if a username of the form user@REALM is
970 specified and no password is specified, do not perform a
971 kinit operation. Only perform the aklog functionality.
973 * Add a new registry value which allows the number of processors
974 on which afsd_service.exe executes to be restricted. Valid
975 values are 1..numOfProcessors
977 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
981 * A second MSI based installer option is now available.
983 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
984 request tickets for user/instance@REALM instead of just user@REALM
986 * Modify the Power Management Notify routine to wait for the Hard Dead
987 timeout period instead of a fixed 19 seconds. With the longer timeout
988 periods Hibernation and Standby could never succeed when network
989 connectivity is not available.
991 * The following fs.exe commands are now restricted to Administrator:
992 - checkservers with a non-zero timer value
995 - sysname with a new sysname list
1004 setting the default sysname for a machine should be done via the
1005 registry and not via "fs sysname".
1007 * NSIS installer adds options to install Debugging Symbols
1008 and the Microsoft Loopback Adapter; the user is now also
1009 given the ability to select the afscreds.exe startup options.
1011 * Build system modified to generate symbols for FREE (aka RELEASE)
1012 builds as well as CHECKED (aka DEBUG) builds
1014 * Sites which have a volume ID of 0x20000001 assigned to their
1015 root.cell volumes have been experiencing problems with accessing
1016 the root.cell volume of their cell when Freelance mode has been
1017 active. This was because 0x20000001 was assigned to the fake
1018 root.afs volume created by freelance. The fake volume id is
1019 now set to 0x00000001 to prevent conflicts.
1021 * The timeout logic in the AFS Client Service has been wrong
1022 for sometime. It is based on two different assumptions.
1023 First, the SMB client timeout is a fix value as was the case
1024 with OS/2 Lan Manager. This assumption is incorrect. The
1025 SMB timeout in Windows is a dynamic value computed based upon
1026 a fixed minimum timeout to which is added time based upon the
1027 size of the request and the performance characteristics of
1028 the connection. Second, it is the responsibility of the
1029 SMB Server to enforce the timeout requirements of the client.
1030 This is untrue. The SMB Server cannot be expected to know
1031 the requirements of the client. More importantly, if the
1032 SMB server uses the SMB client timeout as a value to restrict
1033 its behavior as an RX client, the performance characteristics
1034 of the local SMB session would be used to prematurely terminate
1035 WAN connections with significantly different performance
1038 The timeout logic has therefore been modified in the following
1040 . the Lan Manager Workstation (SMB) Session Timeout is used only
1041 as a basis for configuring the Connection Dead Timeout
1042 and Hard Dead Timeout values. The Connection Dead Timeout
1043 must be at least 15 seconds longer than the SMB Timeout
1044 and the Hard Dead Timeout must be at least double the
1045 Connection Dead Timeout.
1046 . New registry entries have been added to allow the Connection
1047 Dead Timeout and Hard Dead Timeout values independent of the
1048 Lan Manager Workstation Session Timeout
1049 . The test to enforce the SMB Client Timeout has been removed.
1051 One of the side-effects of removing the enforcement of the SMB
1052 Client Timeout is that regardless of whether or not the SMB client
1053 is available to receive the response (and how would the SMB server
1054 know) the RX protocol response can be used to update the AFS
1055 Client Service state for ready access by future SMB client
1058 This should be the end of the "Server paused or restarting messages"
1060 * Add support for arbitrary UNC paths to the pioctl() support.
1061 This enables the fs commands as well as the AFS Shell Extension
1062 to work correctly when UNC paths are being used.
1064 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1065 DNS if the cell configuration cannot be determined via CellServDB
1067 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1068 are ever set more than once at a time
1070 * Fix the management of lists of cm_cell_t structures when using
1071 DNS to lookup cell information. The previous code would fail to
1072 reuse the same cellID for a cell if DNS was used more than once
1073 for a given cell name. When the ttl expired, a single cm_cell_t
1074 could be inserted into the cm_allCellsp list more than once
1075 producing a loop. In addition, the vlServerp list belonging to
1076 the cell was not freed resulting in improper refCounting of the
1079 * Add DNS support to cm_IoctlNewCell() which previous only examined
1082 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1083 to properly garbage collect cm_server_t objects
1085 * Add numVCs variable to smb.c to track the number of smb_vc_t
1086 objects created and use it to initialize the vcID field which
1087 previously was set to 0 in all objects resulting in FindByID
1090 * Fixed DNS lookups to work consistently throughout the OpenAFS
1091 product instead of just from within the afsd_service.exe
1093 * Added a runtime check to ensure that AFS Client Service SMB
1094 Server is accepting connections before attempting to mount
1097 * Read IP addresses for volume servers out of the CellServDB
1098 file if gethostbyname() on the hostname fails.
1100 * Fix getcellconfig() to populate both the Hostnames as well
1101 as IP addresses when loading cell data via DNS
1103 * Increase the Connection Dead Time to 50 from 20 seconds
1104 Increase the Hard Dead Time to 120 from 40 seconds
1105 (matches the Unix values)
1107 * Fixed an assertion validating the number of allocated NCBs
1109 * Fixed the build environment to consistently build for
1110 Windows 2000 and above. (APPVER = 5.0)
1112 * Fixed rx_debug to properly validate the receipt in incoming
1113 data with select() and recvfrom(). Do not copy data out of
1114 the socket buffer unless success is indicated.
1117 * afsd_service.exe will now display a message box to the
1118 desktop when it terminates due to an IP Address Change.
1120 * installer no longer deletes AFS Server configuration data
1123 * installer generates a warning dialog if the RPC service
1124 is not properly configured
1126 * installer compressed with lzma instead of bzip2
1128 * afsd_service.exe shutdown crash solved once and for all
1130 * reference counting of smb_vc_t data structures improved
1132 * name space collision of smb_fid_t event objects corrected
1134 * the output of "fs memdump" is now written to
1135 %WINDIR%\TEMP\afsd_alloc.log
1137 * the file TaAfsApp_1033.dll is now properly installed allowing
1138 the User Manager to start
1140 * a new algorithm is used for computing filename pattern matches
1142 * afscreds.exe now accepts user names containing instance
1145 * Fix the Directory Name Lookup Cache to be case-sensitive.
1146 This is crucial in environments in which a Windows client
1147 is accessing a directory with more than one filename that
1148 differs only by case. If the directory contains "FOO"
1149 and "Foo". You want "DEL Foo" to delete the correct one.
1150 We still have a problem in that "DEL foo" will delete a
1151 random filename. This will be addressed in a future release.
1153 * Fix afscreds.exe -M option (renewMaps) to work when High
1154 Security mode is off. Also, remember to disable the ActiveMap
1155 flag in afsdsbmt.ini when a drive mapping is removed.
1157 * Updates to NSIS installer script. AFS Server configuration
1158 data will not be destroyed on un-install or re-install.
1159 Use a better compression algorithm.
1161 * afslogon.dll now uses KFW to obtain tokens when available
1163 * afslogon.dll when given an all uppercase username will
1164 attempt to authenticate with both the uppercase name
1165 and an all lowercase variation
1167 * DST modification removed. The fix appears to make things
1168 worse after a reboot of the machine.
1170 * fs.exe: added "cscpolicy" which is used to
1171 change client side caching policy for AFS shares
1173 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1174 [-documents] [-disable] [-help]
1176 * Several uninitialized variables have been initialized
1178 * It is now possible to obtain tokens using cross realm
1179 Kerberos within afscreds.exe:
1181 user: jaltman@ATHENA.MIT.EDU
1183 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1184 will will in turn be used to obtain afs@DEMENTIA.ORG.
1185 The resulting token will be stored with the display name
1186 jaltman@ATHENA.MIT.EDU@dementia.org
1188 * aklog.exe has been added to the client
1190 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1191 [[-p | -path] pathname]
1195 -d gives debugging information.
1196 krb_realm is the kerberos realm of a cell.
1197 pathname is the name of a directory to which you wish to authenticate.
1198 -noprdb means don't try to determine AFS ID.
1199 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1200 (default is Kerberos V)
1201 No commandline arguments means authenticate to the local cell.
1204 * All of the resource files have been restructured to adhere to
1205 a set of rules IBM implemented for loading string resources.
1206 These rules had either been forgotten or were not discovered
1207 by folks working on the OpenAFS sources. The end result was
1208 memory corruption. This is primary item which was preventing
1209 the AFS Server from working.
1211 * Increased the size of the maximum ticket size stored in a token
1212 from 344 bytes to 12,000. Increased the buffers used to convey
1213 messages between the pioctl() caller and the SMB Server from
1214 1000 bytes to 12,512. The code appeared to have been writing
1215 above the top of the stack by quite a few number of bytes.
1216 (The increased ticket size is necessary for the next item.)
1218 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1219 Instead the raw Kerberos 5 ticket is used in its entirety. This
1220 is extremely important as it allows us to use pure Kerberos 5 KDCs
1221 as the source of the AFS authentication. The use of up to 12,000 byte
1222 tickets will allow tickets produced by all versions of Microsoft
1223 Active Directory to be used.
1224 - create a user account.
1225 - designate it DES only
1227 - specify its UPN to be "afs@realm"
1228 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1230 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1231 is special when using long file names. (you must use "*.*" and not "*")
1232 Instead only enforce it when performing 8dot3 searches.
1234 * Fixed the DST problem with creation times being set one hour ahead
1236 * Fixed the problem when using \\afs\cell-alias. For example,
1237 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1238 for the alias name; instead simply expand the name. One of the
1239 symptoms of this problem was a loss of acquired tokens.
1241 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1242 of strings. (Only English strings provided.)
1244 * Fixed the installer to properly replace in use files.
1246 * Fixed the build system to cleanup generated component version files
1248 * The release build compiled with MSVC 6.0 compiler to avoid the
1249 afsd_service.exe shutdown crash. This does not solve the problem
1250 but simply avoids it for the time being.
1254 * fix afslogon.dll to not corrupt memory when High Security mode
1257 * fix afsd_service.exe to not attempt to restore the stack when
1258 an exception occurs. (not safe in multi-threaded programs)
1260 * fix uninstaller to properly remove the CRT and MFC DLLs
1262 * remove a Message Box from afscreds.exe when getcellconfig()
1263 fails on a kerberos realm which is not a cell
1265 The following is a list of changes to the OpenAFS for Window client
1268 * "fs setserverprefs" will leave afsd service deadlocked
1270 * "vos listaddrs" will core dump
1272 * installer sets the appropriate keys to support Integrated Logon
1274 * installer disables the "Find Lana by Name" functionality as it
1275 was causing headaches for many users
1277 * fix the intermittent crash of the power management thread when
1278 shutting down the AFS Client Service
1280 * optimizes the obtain drive mount list functionality which is
1281 executed every time the mount tab in afscreds.exe and afs_config.exe
1282 are refreshed. (this happens a lot)
1284 * fix the service shutdown logic. add the STOP_PENDING state
1285 and do not accept additional service events after we declare
1288 The following is a list of changes to the OpenAFS for Window client
1291 * flexelint was run against the source tree and hundreds (perhaps
1292 thousands) of corrections were applied to ensure prototypes
1293 were in use; types were used consistently; variables were
1294 initialized; unused variables were removed; etc.
1296 * A wide variety of instrumentation was added including the
1297 ability to produce a stack trace from within afsd_service.exe
1300 * Dynamic configuration of the RDRtimeout value based upon the
1301 LanMan Workstation Session Timeout
1303 * The mount root no longer needs to be called "/afs". This
1304 is now set by a registry value "MountRoot" within the key
1305 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1307 * The cell list is now only read out of afsdcell.ini when the
1308 file changes instead of each time a cell is resolved.
1310 * Thread synchronization was added to cm_server.c and ktc_nt.c
1312 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1313 calloc()/free(). The Global functions were needed on Windows 3.x
1314 but have caused a variety of problems on the Win32 platforms.
1315 Avoiding them is highly recommended by several Microsoft
1316 Knowledgebase articles
1318 * Support for Symbolic Links added to the AFS Shell Extension
1320 * Added a registry value "OverlayEnabled" to determine if
1321 Shell Extension Overlays should be enabled.
1322 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1324 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1325 separate trees for checked and free builds. Build system supports
1326 a custom directory src\WINNT\extra which can be used as a grafting
1327 location of organization specific additions to the build tree.
1329 * New installer built using NSIS 2.0.
1331 * Named all kernel objects in order to allow them to be monitored
1332 with tools such as SysInternals' ProcExp.exe.
1334 * Introduced new EventLog framework for AFSD
1336 * Introduced Power Management interface to AFSD for Standby and
1337 Hibernate modes to allow cache to be flushed prior to network
1340 * Utilize Win32 DNSQuery API instead of internal routines. This
1341 allows DNS SRV queries to be sent to all current domain name
1342 servers. Not just one specified in an INI file. DNS is now
1345 * "NetbiosName" registry value may be used to specify a fixed
1346 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1347 when the loopback adapter is in use. If you need to use the
1348 old notation with a loopback adapter installed specify a registry
1351 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1353 * Refactor all modules which depend on LAN Adapter and NetbiosName
1354 determination in a new library: lanahelper.lib. This allows for
1355 consistent behavior throughout the product.
1357 * Move the afsd.log and afsd_init.log files to the directory specified
1358 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1359 for services. Added the Date to the log entries.
1361 * New registry value "RxMaxMTU" used to limit the size of the RX
1362 packets sent by the AFS Client Service to the Server. In order
1363 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1364 size must be restricted to 1264 or smaller. The latest NSIS
1365 installer sets a value of 1260 by default.
1367 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1368 packets. This is not needed in order to work across the Cisco
1369 VPN but might be needed for other network environments. This
1370 value is not set by the NSIS installer.
1372 * New registry value "HideDotFiles" is used to apply the Hidden
1373 attribute to files whose names begin with a '.'. This value
1374 is set by the NSIS installer.
1376 * New registry value "MaxMpxRequests" allows the maximum number
1377 of multiplexed sessions to be configured at run time. This
1378 value is not set by the NSIS installer. The default value is
1381 * New registry value "MaxVCPerServer" allows the maxmimum number
1382 of VCs per server to be configured at run time. This value is
1383 not set by the NSIS installer. The default value is 100.
1385 * New registry value "AllSubmount" allows the "all" submount to
1386 be disabled by setting its value to 0x00.
1388 * Allow cells names to be valid mount points
1389 \\<netbiosName>\<cellname>
1391 * Store the active state of drive mappings in order for afscreds.exe
1392 to restore them upon startup
1394 * Add exception handling to generate a Stack Trace to the afsd_init.log
1395 file if one happens to occur.
1397 * Add lots of logging to help detect the cause of invalid SMB packets
1399 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1400 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1401 renewal of expiring tokens as long as afscreds.exe is running.
1403 * New afscreds.exe command line options:
1405 -M = renew drive maps
1406 -N = ip address change detection
1409 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1410 determines whether or not MIT Kerberos for Windows should be used
1411 to obtain tokens via Kerberos 5 tickets.
1413 * New registry value "AfscredsShortcutParams" in
1414 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1415 determines the command line parameters to be specified when "fixing"
1416 the AFS Shortcut in the user's startup folder.
1418 * The "ShowTrayIcon" registry value has been moved from
1419 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1420 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1422 * The <cell name> registry values used to store the token expiration
1423 reminders have been moved from
1424 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1425 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1427 * Obtain the Logon User Name from the Explorer key when available
1429 * new text document doc\txt\winnotes\registry.txt lists all registry
1430 values used by OpenAFS (excluding the AFS Server)
1432 * BUG: rx_securityClass objects were not properly reference
1433 counted and were never freed.
1435 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1436 would be generated. The existence of a server does not imply
1437 that it is not down. If all of the servers for a cell are down
1438 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1441 * BUG: the directory name lookup cache failed to free the entries
1442 in the cache when the name cache entries cycled. The entries
1443 in the cache would become dereferenced without being freed.
1445 * BUG: fs setserverprefs could be executed without Administrator
1448 * BUG: the number of allocated NCB objects (100) exceeded the number
1449 which could actually be waited upon by the kernel (64). Any objects
1450 which were utilized above the limit could never have event completions
1453 * BUG: smb_username_t objects were not being reference counted and
1454 were not properly freed.
1456 * BUG: smb_tid_t objects could under unusual circumstances be freed
1457 before they were no longer referenced.
1459 * BUG: smb_fid_t object pointer were frequently used even when
1460 their value could be NULL. They were not properly released and
1461 therefore they were never freed.
1463 * BUG: smb_packet_t data structures were not completely initialized
1466 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1467 Denied" because that causes the Explorer Shell to try again until
1468 access is obtained. Instead return "Remote Resources" which allows
1469 the shell to move on and treat the error as transient.
1471 * BUG: when initializing the NCBreturns structure, separate Event objects
1472 were created for each NCB although a single Event object was supposed
1473 to be shared by all.
1475 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1478 * BUG: smb_tran2Packet_t objects were not being properly referenced
1481 * BUG: directory path creation did not handle the case of multiple
1482 directories requiring creation in one attempt
1484 * BUG: SMB requests which required an Extended Response were ignored.
1485 This prevented some files from being written to AFS volumes.
1487 * BUG: character strings were being freed even after they were
1488 inserted into in use data structures
1490 * BUG: inconsistent usernames were used when High Security mode was
1491 enabled. (there is still much to do in this area)
1493 * BUG: pioctl() calls which require out of band RPC operations were
1494 susceptible to race conditions when performed by multiple processes
1496 * BUG: memory allocation and deallocation crossed instances of the
1497 C Runtime Library producing memory leakage and corruption in
1498 afscreds and the client configurator.
