2 * Enforce the delete on close flag specified by the NTCreateX()
5 * A race condition in the rx library was fixed that resulted in
6 a deadlock in rx_NewCall when the RX_CONN_MAKECALL_WAITING flag
7 was cleared when threads were still waiting to use the
8 connection. Also, fixed a potential case in which the
9 connection could be destroyed while threads were waiting to use it.
11 * The DNLC freelist has been seen to become corrupted with still
12 active entries being stored on the freelist. Changes were made
13 to perform a better job of cleaning entries before placing them
14 onto the freelist; marking them with the correct magic value when
15 purging the list; and allowing the list to be purged on startup
16 if the cache validation fails.
18 * Windows Crash Reporting does not get triggered for afsd_service.exe
19 because it provides its own top level exception handler. This patch
20 places an explicit call to ReportCrash() on platforms which support
23 If you configure Crash Reporting via AD Policy to capture crash
24 reports within the domain, then you will receive this output.
26 * Generate MiniDumps independent of the Windows Crash Reporting.
28 (a) If an exception occurs,a minidump will be generated at the path
29 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
30 can be set to any other type via use of the
33 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
35 (b) MiniDumps can be generated at any time using the "fs minidump"
36 command. This allows you to generate a minidump without
37 stopping the process or even requiring the use of a debugger
40 * an RX connection which reports bad ticket now treats it the same way
41 the expired ticket is treated. The ticket is removed from the
42 connection and a new anonymous connection is established.
44 * fs memdump now requires that the caller be in the AFS Client Admins
47 * additional debugging information is provided in cm_Analyze when the
48 error code is ignored.
50 * Fix a regression introduced into the pioctl() client code which
51 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
52 MIT KFW is not installed. (1.3.82a)
54 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
57 * Fix a race condition in cm_EndCallbackGrantingCall() that
58 could leave 'nrevp' pointing to freed memory. In the process,
59 optimize the processing to ensure that the applications monitoring
60 the status of the stat cache entry are only notified at most
63 * Conditionalize access to the Explorer Shell AFS->Mount Point
64 ->Remove menu item. Disable the item if the selected item(s)
67 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
68 Local Storage. This eliminates thread contention on the
69 global RX free packet queue. This should improve performance
72 * Fix the IP address filtering code to properly load/unload
73 the IPHelper DLL so that Windows XP/2003 and beyond systems
74 do not have to manually probe the registry.
76 * CleanupACLEnt() was not being called consistently with
77 the cm_scache_t object referred to by the back pointer
78 mutex locked. This could in very rare conditions lead to
79 an invalid memory access.
81 * Added a script command to the msi installer "afs_replace"
82 which can be used to replace one version of OpenAFS with
83 another without requiring an uninstall and reinstall if
84 the installed msi is no longer in its original location.
86 * Apparently the problem with multi-domain forests with cross-
87 realm trusts to non-Windows realms was not entirely solved.
88 The authentication to the AFS SMB service failed because
89 the wrong name was being used. Using ASU as an example,
90 the authentication was being performed with the name
91 "QAAD\user" (an account in the forest root) and not
92 "user@ASU.EDU (the MIT Kerberos principal used to login with)
94 The solution was to add an additional dependency on KFW
95 in order or to be able to easily obtain the client principal
96 name stored in the MSLSA ccache TGT. This information is
97 used in two locations:
99 - the pioctl() function
101 - a new WinLogon Event Handler for the "logon" event.
103 The pioctl function will now be able to use the correct
104 name when calling WNetAddConnection2() and the "logon"
105 event handler will now be able to call WNetAddConnection2().
106 The hope is that the "logon" event handler will be called
107 before the profile is loaded but I have not guarrantee
111 * Fixed a locking error in cm_TryBulkStat() which had the
112 potential of deadlocking the system for the length of time
113 it takes to perform a bulk status fetch operation.
115 * Replaced time conversion code (UnixTime <-> FILETIME) to
116 be completely arithmetic instead of relying on a bizarre
117 algorithm involving a variety of C RTL time functions.
118 This has the side effect that UnixTime and FILETIME which
119 are both stored in UTC are interpretted as UTC throughout
120 the year. Windows will apply the same localization to AFS
121 as it does to NTFS. Applications which rely on the ability
122 to sync files between the two file systems will no longer
123 see the timestamps of files in AFS change an hour relative
124 to the files stored in NTFS or Windows based backup devices.
126 * Fixed a invalid memory access under a bizarre circumstance.
127 Windows will allow a physical mass media device to be
128 installed via Plug N Play to the system and will assign it
129 the lowest available drive letter. This is true even if the
130 drive letter is currently assigned in the user session to
131 a network device via NET USE (or its equivalent.) When this
132 happens, queries sent to the CIFS server will contain invalid
133 data. This invalid data was not being caught by the AFS
134 Client Service and was resulting in a crash when Freelance
137 * Fixed a reference count error when registering callbacks
138 on a stat cache object if the callback was already registered
140 * Add a case to cm_Analyze() in order to handle the case where
141 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
142 the server list for the volume is empty. In this case, force
143 an update of the volume info and retry.
145 * Insert a missing cm_EndCallbackGrantingCall() which could
146 result in threads waiting for a callback to complete to never
149 * In the persistent cache, there is a maximum number of volume
150 entries. Allow volume entries to be reused if the maximum
151 number have been allocated and their reference count is zero.
153 * If we already have a dead virtual connection object, don't
154 ignore the fact that additional dead vc objects must be taken
157 * Removed a deadlock condition introduced in the summer of 2004.
158 Do not hold mx locks around calls to RX functions including
159 rx_NewCall(). That is what reference counts on the rx_connection
162 * Fixed an initialization error in afslogon.dll which could
163 result in random behavior including a failure to terminate
164 the NPLogon function. (1.3.80b)
166 * Fixed an error preventing the use of SMB authentication
167 on Windows 2000. (1.3.80a)
170 * Updated CellServDB to Public CellServDB 16 Mar 2005
172 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
173 misinterpretted as "csail.mit.edu" when the resolver
174 is configured to append ".mit.edu" to failed DNS queries.
176 * Fixed another case in which the client would replace connections
177 to the host when it was not necessary. In this case the
178 situation would occur if cryptall was on and the connections
179 were unauthenticated due to lack of an appropriate token.
181 * OpenAFS for Windows has failed to work at sites which are
182 utilizing a cross-realm trust between an MIT/Heimdal realm
183 and a multi-domain Windows forest when the workstation being
184 accessed is not located in the root domain. This is caused
185 by a bug in the workstation which was triggered after the
186 introduction of Windows 2003 Server. When the bug is triggered,
187 the workstation attempts to authenticate users to afsd_service.exe
188 by contacting the Domain Controller instead of using the
189 LSA loopback authentication mechanism.
191 One of the reasons this bug occurs is because the workstation
192 does not have a reliable way of knowing that the service whose
193 netbios name is "AFS" is located on the workstation. This will
194 be fixed starting in Longhorn Beta 1 by Microsoft. The
195 "BackConnectionHostNames" registry value will be used to
196 indicate that the authentications to that service name should
197 be performed using the loopback authentication mechanism.
199 In the meantime, when Logon Caching is enabled, we can force
200 afsd_service.exe to authenticate using the logon cache before
201 contacting the Domain Controller. This will work with both
202 password and smart card based logons.
204 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
205 flag should not be cleared if a volume's server reference is
206 marked as "offline". In the case where all of the volume's
207 servers are either "down" or the volumes are "offline", we want
208 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
209 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
210 should never occur in practice.
212 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
213 5 seconds, clear the server down and volume busy flags, and
214 then force an update from the VLDB. This allows the client to
215 update the location of a volume if the reason for it being
216 marked offline is because it is being moved. Calls to
217 cm_ConnByMServers() will be retried either until success or
218 the RDRtimeout period is reached.
220 * Correct the Power Management code behavior in response to
221 Standby, Suspend, and Shutdown events. Instead of flushing the
222 buffers associated with the mounted SMB submounts, simply write
223 all buffers which are marked dirty.
225 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
226 provides a list of cells other than the default cell for which
227 tokens should be obtained using the default Kerberos principal.
228 This functionality is logon domain specific and is only available
229 when using KFW for authentication.
231 * Fixed FindNext Invalid Handle error caused by over agressive
232 attempts at garbage collecting dirSearch entries when the
233 dirSearch ID wraps from the maximum value to 1.
235 * Add support for registry defined server preferences for VLDB and
236 File servers. See registry.txt for details.
238 * Increased default cache size to 96MB and default number of cache
241 * Fixed refCount leaks related to directory lookups and pioctl calls.
243 * Callbacks revoked during a race condition with an attempt to
244 obtain the same callback no longer result in an inaccessible
247 * New command line tool:
249 afsdacl : Set or reset the DACL to allow starting or stopping
250 the afsd service by any ordinary user.
252 Usage : afsdacl [-set | -reset] [-show]
254 -reset : Reset the DACL
255 -show : Show current DACL (SDSF)
257 * IP addresses are no longer queried once at startup. Instead IP
258 addresses are obtained as needed. Loopback adapter addresses are
259 no longer published to the server.
261 * Pay attention to the MIT KFW registry configuration for automatic
262 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
264 * Fix (once again) case-sensitive comparisons which was apparently
267 * Activate support for vos listvol -format
269 * Population of the "AFS Client Admins" group failed on non-English
270 versions of Windows because the name of the "Administrators" group
271 is localized. Now we lookup the name of the group by using the
272 Administrators Group Alias Relative ID.
274 * Multiple cell token acquisition within afscreds.exe was broken in the
275 case of Kerberos 5 cross realm authentication. Instead of contacting
276 the KDC associated with the cell's realm, afscreds would obtain a
277 token from the KDC of the user's realm. This would result in
278 "invalid kvno errors" while authenticating to the AFS servers.
279 Unauthenticated access would work. The symptoms would vary based upon
280 whether or not the VLDB servers had been contacted using unauthenticated
281 connections prior to the user obtaining tokens.
283 * The list of ACL entries was becoming corrupted. It appears as if
284 an ACL when it expires was not being appropriately cleaned up. In
285 fact, it was left in the list of ACLs associated with the scache
288 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
289 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
290 and "amd64_win64" for amd 64-bit processors.
292 * When executing executables, Windows provides a mechanisms by which
293 the normal search for DLLs can be bypassed. If a file foo.exe is
294 being executed and there exists a file or directory "foo.exe.local"
295 (the contents are ignored if a file), then Windows will search for
296 DLLs first in the "foo.exe.local" directory and second in the
297 directory in which the "foo.exe" file is located.
299 Previous releases of OAFW would improperly return
300 STATUS_NOT_A_DIRECTORY instead of the expected
301 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
302 to terminate the search for the DLL causing the execution of the
305 * Rework the reference counting of smb_vc_t objects. The references
306 stored in the waiting locks were not counted. This could result in
307 an assertion if the reference count drops to zero.
309 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
310 when running in freelance mode.
312 * Added support for persistent caching of file contents, stat entries,
313 volume data, cell data, and name lookup data. When the registry
314 value, "NonPersistentCaching", is not defined or set to 0 the file
315 specified by "CachePath" becomes a persistent cache file. The
316 size of the cache file is computed at run time. It has a maximum
317 size of approximately 1.2GB. The contents of the file will be
318 validated according to the rules specified by the "ValidateCache"
321 * Added support for UUIDs. UUIDs are kept for as long as the
322 cache file is intact.
324 * Added cmdebug.exe and support cache manager debugging callback
325 interfaces in afsd_service.exe.
327 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
328 [-addrs] [-cache] [-help]
329 Where: -long print all info
330 -addrs print only host interfaces
331 -cache print only cache configuration
333 * Symlinks to \\AFS\[all\]... will now be treated the same as
334 symlinks to /afs/.... However, please use /afs/... as otherwise
335 the symlinks won't work on Unix.
337 * Correct a problem with local CellID allocation for cells whose
338 server list is obtained via DNS instead of a CellServDB file. If
339 the DNS information expires the CellID assigned to the entry will
340 be changed. This causes all of the cm_scache_t objects which refer
341 to the old cellID number to become useless. Attempts to access
342 files or directories with cm_scache_t objects using the old cellID
343 will fail since the server list cannot be obtained.
345 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
346 be triggered if the volume referenced by the cm_scache_t object is
349 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
350 in addition to SERVICE_ACCEPT_STOP.
352 * Move RPC shutdown until after the SMB and RX shutdown procedures
353 complete. Block until RPC shutdown is complete.
355 * Modify afslogon.dll (integrated logon) to wait for service if its
356 state is START_PENDING. If the timeout period occurs, reset to
357 the retry interval and not the sleep interval.
359 * When renewing the server list for a cell obtained via DNS AFSDB
360 records, the cm_cell_t entry must be removed from the list of all
361 cells. Otherwise, the list of cells will be corrupted.
363 * In the dcache and scache modules, use the cm_scache_t dataVersion
364 instead of the cm_fakeDirVersion.
366 * Synchronize fs.c with the unix version.
368 * The variable used to determine whether a file or virtual memory
369 mapped cache is used was not properly initialized to a default
370 value. If the registry setting "NonPersistentCaching" was not
371 set, the choice would be random. Properly initialized to be
374 * The memory mapped view was never unmapped before closing the file
375 at service shutdown. This is now properly cleaned up.
377 * Default location of Cache file is now %TEMP%\AFSCache
381 * A bug affecting new installations of 1.3.75/76 would result in
382 the creating of incorrect mountpoints in the freelance root.afs
383 volume for the default cell.
385 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
386 of "root.cell", you have been affected by the bug. To correct the
387 problem, execute the following commands:
389 fs rmmount \\afs\all\<cellname>
390 fs rmmount \\afs\all\.<cellname>
392 fs mkmount \\afs\all\<cellname> root.cell <cellname>
393 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
397 * A bug has been fixed in the auto-generation of Freelance root.afs
398 symlinks which produced random entries in the \\AFS\all directory.
400 * Support has been added for multi-homed servers
403 * Added a new registry value, "StoreAnsiFilenames", which can be used
404 to force the use of ANSI character sets instead of OEM Code Pages.
405 This feature is useful when users require the ability to create
406 filenames with 8-bit characters and need to access the files from
407 both Latin-1 based Unix systems as well as from Windows.
409 Activation of this feature will prevent access to files stored with
410 8-bit OEM characters.
412 * Shutdown all SMB threads in a synchronized manner when stopping the
415 * There is currently a maximum cache size of 1.3GB. The limit is imposed
416 by the largest contiguous block of unused memory within the 2GB process
417 space which can be assigned to the memory mapped file. Unfortunately,
418 when the executable digital signature verification code is activated
419 Windows sees fit to further segment the process memory which in turn
420 reduces the size of the maximum cache file to less then 800MB. If
421 larger cache sizes are desired, a new registry value should be set:
423 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
425 Setting this value will disable the runtime verification of digital
426 signatures on afsd_service.exe and the afs dlls which it loads. It
427 will not disable the the version number check on those same files.
428 The signature verification is not a security messure and is only meant
429 to enhance the ability to afsd_service.exe to detect potential
430 destablizing mixtures of DLLs from incompatible distributions.
432 Added code to auto-disable the signature verification check if
433 the desired cache size is greater then 700MB.
435 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
436 used to verify the validity of the afsd_service.exe binary
437 as well as each of the AFS DLLs loaded by the service. Not only
438 must the digital signature be valid but the signatures of the
439 DLL must be signed by the same entity as the service.
441 * Implement new functions: cm_freelanceMountPointExists and
442 cm_freelanceSymlinkExists. Use them along with other validity
443 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
444 ensure that name collisions do not occur and that empty strings
445 are not valid file names.
447 A symlink may not have a name which would resolve to a valid
448 cell name. Doing so would prevent access to the cell.
450 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
451 re-initialization code. The reference counts of the fake root.afs
452 volume scache object(s) would become invalid when the mount point
453 or symlink lists were altered.
455 * Add registry entries to provide mappings from the afsdsbmt.ini
456 to the new locations for applications which count on the use
457 of the old Profile file APIs. These apps are likely to fail
458 if the user does not have administrator privileges and the
459 registry is locked down.
461 * The afs_config.exe submounts dialog had two errors.
462 First, attempts to remove entries failed because the registry
463 key was being opened without KEY_WRITE privileges.
464 Second, when editing a submount entry, changing the name
465 would add a new key and leave the original one in place.
466 Now the original submount will be removed if its name is
469 * In recent months there have been several incidents in which
470 users have experienced problems starting or accessing
471 afsd_service.exe and after significant effort has been spent
472 it has turned out that they have two versions of AFS on the
473 machine or an inconsistent set of DLLs.
475 Code has now been added to afsd_service.exe which will walk
476 the list of modules loaded by afsd_service.exe and validate
477 that the version of the AFS DLLs matches the version of the
478 afsd_service.exe executable. If they do not match the service
481 * When Freelance mode is enabled and there is no registry
482 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
483 will attempt to import the afs_freelance.ini file contents.
484 If the file does not exist, it was creating a dummy file
485 with a r/o and r/w entry for the default cell and then
486 importing those values.
488 This process has been changed. The temporary file is no
489 longer created. Also, both the OpenAFS Client install
490 directory as well as %WINDIR% are checked for previous
491 afs_freelance.ini files.
493 * Added support for VL_GetEntryByNameN(). Still need to add
494 support for VL_GetEntryByNameU() for multi-homed support.
496 * Fix a deadlock situation in afscreds.exe when canceling an
497 auto-generated Obtain Tokens dialog
500 * Fix the locking of objects during Directory Searches in the
501 SMB/CIFS server. The failure to properly lock the reference
502 counts was resulting in the premature freeing of smb_dirSearch_t
503 objects while they were still in use by the SMB/CIFS client.
504 This does not solve the "Invalid Handle" problem.
506 * Fix Find Cell By Name pioctl call to return a valid cell
507 name for the Freelance fake root.afs volume.
508 "Freelance.Local.Root".
510 * Fix the Explorer Shell Extension Symlinks->Add operation.
511 The dialog template was missing and the link destination
512 string was too short.
514 * Add support for symlinks to Freelance root.afs volume
515 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
516 <number> = "<linkname>:<relative-path>."
517 Use symlink.exe to create, list, or remove
519 * Remove the fallback to the use of KFW's KRB4 library when obtaining
520 tokens. We never obtain KRB4 tickets.
522 * Fix AFS Client Configuration Control Panel to support new SysName
525 * Fix a bug in afsd_service.exe which could result in the SysName
526 not being read from the registry.
529 * Add code to block the issuance of AFS tokens by aklog.exe or
530 afscreds.exe when the Kerberos 5 principal name contains a dot.
532 * Modify the IsAdmin() function to always treat the local SYSTEM
533 account as an AFS client administrator. Affects fs.exe and
536 * Modify the internal handling of Quota Exceeded errors
538 * Upgrade all reference count fields in the Windows cache manager
539 and the osi library to use unsigned long instead of signed short.
540 A similar fix has been applied to the afs rpc (rx) library.
542 * fix the Windows cache manager to prevent it from replacing the
543 rx_connection object associated with the cm_conn_t object on each
544 and every operation if "fs crypt" was set. This explains the
545 dramatic performance difference when crypt is used vs clear.
546 The problem: 'cryptall', a boolean flag indicating whether or not
547 "fs crypt" is set, was being compared to the rx_connection
548 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
549 1 != 2 and therefore the rx_connection was always destroyed
550 and replaced on each and every operation.
552 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
553 It is not safe for the cm_conn_t object to not be locked because
554 rx_DestroyConnection might be called from another thread if:
555 - the user's tokens have changed or expired
556 - the crypt mode has changed
558 This fix appears to have also taken care of the problems associated
559 with Overlapped Writes resulting in Delayed Write errors.
561 * fix NSIS installer's AdminGroup.exe to properly create and
562 remove groups when given -create or -remove. The string comparison
565 * fs sysname now accepts a list of sysname values
567 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
568 DWORD which when set to a non-zero value will cause error message
569 text to be output to stderr from the pioctl() routine. Useful in
570 debugging failures of fs.exe, tokens.exe, etc.
572 * added a test to the power management code to only perform a
573 flush operation if there is at least one network adapter which
574 is not a loopback adapter.
576 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
577 "EnableKFW". This value will not be read if the key
578 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
579 value under that key does not.
581 * provide mechanisms to force the use of krb524d for Kerberos 5
582 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
583 there is a new registry value "Use524" and for aklog.exe a new
584 command line parameter "-m".
586 * Fix the pattern matching algorithm to properly match patterns
589 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
590 which is used by both the original function and the new
591 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
592 creation of HardLinks in addition to Renaming. smb_Link()
593 is a new function which creates HardLinks via cm_Link().
594 cm_Link() is a new vnodeops function which creates links
597 smb_ReceiveNTRename() does not support the File Copy and
598 Move Cluster Information operations described in its interface.
599 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
601 * When opening files via symlinks, we should follow the symlinks
602 until we reach the actual file stat cache entry. The stat cache
603 entry of the file should then be stored in the FID instead of
604 stat scache entry of the symlink.
606 * return bad operation errors for all unimplemented functions
607 even if we do not know the functions exist.
609 * Log bad packets and unknown operation packets to the trace log
611 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
614 * Update list of known CIFS operations to include all those listed
615 in CIFS-TR-1p00_FINAL.pdf.
617 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
618 to support the REG_EXPAND_SZ type.
621 * A new Windows authorization group "AFS Client Admins" is now
622 created and populated with the members of the "Administrators"
623 group. The group is used to determine which accounts on the
624 machine may be used to modify the AFS Client Configuration via
625 the UI and command line tools. afs_config.exe, fs.exe,
627 * Modify the WinLogon Logoff Event Handler to query NT4 domain
628 controllers for the remote profile path if Active Directory
629 services are not available.
631 * Fix aklog.exe to not add the AFS ID to the username
633 * PTS registration of new users to foreign cells has been added to
636 * The cm_Daemon thread is used to perform checks for
637 down servers, up servers, volumes, callback expirations,
638 lock maintenance and token expiration. Due to a gaff in
639 larger integer division the thread never performed any
640 work. Instead the current time computation would always
641 be less then the trigger times. This had an adverse affect
642 on the client's ability to maintain communication with servers,
643 keep volumes up to date, and flush user tokens and acls
644 when they have expired. This was broken when the 1.3 branch
645 was modified to support VC7 which no longer included
648 * An initialization problem with the Freelance code was
649 detected while fixing the callbackRequest. The cm_rootSCachep
650 object is obtained during afsd_InitDaemons() but the callback
651 information is incomplete. The callback information will not
652 be obtained until cm_MergeStatus is called from within
653 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
654 test for the conditions under which the callback information
657 * Reports have been filed indicating that callbacks were
658 being lost. An examination of the code indicated that the
659 cm_server_t objects were not being properly reference
660 counted by the cm_scache_t and cm_callbackRequest_t objects.
661 In particular, the cm_server_t objects may have been freed
662 from beneath the cm_conn_t objects.
664 All of the reference counting is now done via the functions:
669 this improves the ability to track the referrals.
671 Each cm_BeginCallbackGranting Call now allocates a reference
672 to the cm_server_t. The cm_EndCallbackGrantingCall either
673 frees the reference or transfers it to the cm_scache_t
674 cbServerp field. These are then appropriately tracked
675 through the cm_Analyze call.
677 * Ensure that the dnlc hash table is the same size as the
678 dir name hash table (as per original author's note).
679 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
680 for compatibility with 64-bit systems.
682 * fix smb_ApplyV3DirListPatches to properly apply the hidden
683 attribute to dotfiles when the infoLevel < 0x101 and
684 cm_SyncOp has failed.
686 * Fix the Freelance registry initialization code. There
687 was a possibility that some systems could end up with
688 garbage in the registry during a clean install.
691 * file and directory names beginning with "." will now be given the
692 hidden attribute when the volume access is anonymous. this matches
693 the behavior when the volume access is via an authenticated user.
695 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
696 key. When a change occurs mark the root.afs data as invalid and
697 for it to be reloaded on the next access. This allows administrators
698 to modify the mount point list without restarting the service.
700 The freelance client used to provide a fake modification time for
701 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
702 Added code to extract the last modification time of the Freelance
703 registry key and use that instead. The time now represents the
704 most recent mount point change.
706 * PTS registration of new users to foreign cells has been added to
709 * Additional Cache Control and Credential Manager options have been
710 added to the WiX installer. See deployment guide for details.
712 * The CachePath setting is now optionally a REG_EXPAND_SZ type
714 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
717 * The loopback installation code may have had a problem updating the
718 %ETC%\HOSTS file which could have resulted in a premature failure.
719 Work around code has been added for the case where the file cannot
722 * The default max chunksize was increased from 15 (32K) to 17 (128K)
723 because Windows sends 64K blocks when using overlapped writes.
725 * The default number of server threads was increased from 4 to 25 to
726 better handle overlapped writes.
728 * The "AfscredsShortcutParams" registry value was not being properly
729 loaded by afscreds.exe. Therefore, the default value was always being
730 used instead of the value set by the installer.
732 * Windows XP provides downgrade attack detection to prevent an attacker
733 from being able to force the use of NTLM simply by disrupting
734 communication with the KDC. This attack cannot exist between the
735 Windows CIFS client and the AFS Client Service. Therefore, when a
736 downgrade has been detected the afs pioctl library will force the
737 establishment of a new CIFS connection using NTLM.
739 * A locking error was discovered surrounding all references to volume
740 server lists within the cm_cell.c source file.
742 * The logged into Windows username was incorrect on Terminal Server
745 * A new registry value "NonPersistentCaching" was added to the service
746 parameters key. When set to a non-zero value, the afs cache is stored
747 in the Windows paging file. There are two limitations to choosing
749 1. when persistent caching is implemented it won't work with
750 this flag set since there will be nothing to persist.
751 2. with this flag set the initial paging allocation cannot be
752 changed while the service is running
754 * An initialization bug was discovered in aklog.exe which affected users
755 who have a domain name for their afs servers which could not be mapped
759 * afs_config.exe now validates cell names against DNS in addition
760 to the CellServDB file.
762 * In order to allow the freelance client to connect to a volume with ID
763 equal to 1 on the default cell we changed the fake root.afs volume ID
764 once again. This time we choose 0xFFFFFFFF. In addition, we change
765 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
766 It will now be impossible for a volume ID to match that of another
767 cell unless the client is connected to 0xFFFFFFFD cells. That should
768 be enough room for growth.
770 * Fix "fs mkmount" command to work with UNC paths and when
771 started from non-AFS drives. It is now possible to create a mount
772 point in the freelance fake root.afs volume with the command
774 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
778 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
779 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
781 * The algorithm used to re-attempt access to the servers associated with
782 a volume has been altered to properly address the case in which all
783 servers have been marked down. The previous algorithm did not reset
784 the server's down flags so the servers were never actually retried.
785 This caused a problem with active volumes if the network connectivity
786 was lost as could be the case with a network cable removal, wireless
787 drop, or laptop hibernation. With the fix volume access is restored
788 almost instantenously when network connectivity becomes available.
790 * Support for SMB/CIFS browsing has been added to the AFS Client Service
791 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
792 listing of AFS submounts and freelance mount points. Support for
793 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
794 significantly enhances the behavior of AFS volumes within the Explorer
795 Shell. For instance, "AFS" now shows up as server in the Explorer
796 with each submount or freelance mount point visible as a share.
797 The right click menu in each folder now works with full functionality
798 on a consistent basis.
800 * The network provider can be configured to have different behavior
801 depending on the domain that the user logs into. These settings are
802 only relevant when using integrated login. A domain refers to an
803 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
804 local machine (i.e. local account logins). The domain name that is
805 used for selecting the domain would be the domain that is passed into
806 the NPLogonNotify function of the network provider. (see registry.txt
809 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
810 "Authentication Cell" which may be used to specify a default
811 authentication cell for afscreds.exe which is different from
812 the default cell for the AFS Client Service daemon.
814 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
815 afslogon.dll moved to %WINDIR%\System32\.
816 New registry entries added to register the dll for Winlogon events.
818 The logoff event will now force a call to ktc_ForgetAllTokens()
819 using the context of the user being logged off as long as the
820 user's profile is not loaded from within AFS. If the profile
821 was loaded from AFS we can't release the tokens since the Logoff
822 event is triggered prior to the profile being written back to
823 the its source location. This is now performed in an XP SP2
826 * Windows XP SP2 Internet Connection Firewall interoperability
829 * The %WINDIR%\afsdsbmt.ini contains four sections:
830 Submounts, Drive Mappings, Active Maps and CSC Policies.
831 The Submounts and CSC policies are now stored in the registry under
832 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
833 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
834 The Drive Mappings and Active Maps are stored in the registry under
835 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
836 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
838 There is no automatic migration of this data as it would be impossible
839 to consistently migrate data to user profiles which may not be active
840 when the machine is updated.
842 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
843 fake root.afs volume. For the same reasons as for the cellservdb file,
844 this information should not be in %WINDIR%. This information is now
845 kept under the registry key
846 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
848 The data from the afs_freelance.ini file will be automatically
849 migrated to the registry on first execution of afsd_service.exe
851 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
852 troublesome for several reasons. One, it is confusing for those who
853 expect the file to be named "CellServDB" instead of "afsdcell.ini".
854 Two, this file is not a Windows Profile formatted file. Three,
855 applications should not be reading or writing to %WINDIR%. It causes
856 problems for Windows Terminal Server.
858 The new location of CellServDB will be the OpenAFS Client install
859 directory which is by default C:\Program Files\OpenAFS\Client and can
860 be determined by querying the registry for
861 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
863 The existing afsdcell.ini will be migrated by the NSIS installer.
864 The Wix installer must still be updated to do the same.
866 * Change NSIS installer to use DNS by default; to remove Integrated Logon
867 High Security mode; and to add Terminal Services compatibility registry
868 entries to allow the OpenAFS tools to find the afsdcell.ini and other
869 configuration files in %WINDIR%.
871 * Add support for authenticated SMB connections. This will remove
872 the need for high security mode in most situations. Both NTLM
873 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
874 only NTLM can be used even though Kerberos is now supported. The
875 reason is that it is not possible to construct a service principal
876 which is unique to each individual machine.
878 SMB Extended Auth does not work on XP SP2 unless one of two registry
879 modifications are made:
881 (1) To disable the check for matching host names on loopback connections
882 set this key. This does not require a reboot:
884 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
885 "DisableLoopbackCheck"=dword:00000001
887 (2) To add the AFS SMB/CIFS service name to an approved list. This
888 does require a reboot:
890 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
891 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
893 afsd_service.exe will automatically add the current Netbios Name
894 to the BackConnectionHostNames list and then temporarily disable
895 the loopback check for one cycle of startup/shutdown of the service.
896 We assume most folks do not start/stop without a reboot so this
897 will be adequate in most cases.
899 * Fix security hole in afslogon.dll which allowed passwords to be
900 sent in clear text to the KDC in a misformed principal name.
902 * Fix cm_GetCell() to properly handle expired dns entries
905 * If Freelance mode is active and the afs_freelance.ini
906 file does not exist, do not create an empty file.
907 Instead create a file containing ro and rw mountpoints
908 to the default cell using the standard conventions.
910 * Modify the Freelance support to handle the ability
911 to create rw mount points in the fake root.afs volume.
913 * Changed the RPC mechanism used for token setting from
914 named pipes to local. Use of named pipes can be restored
915 by setting the environment variable AFS_RPC_PROTSEQ to
918 Named pipes were required when a Windows 9x system was
919 using a NT system in gateway mode which is incompatible
920 with our use of local loopback adapters.
922 * In afscreds.exe, if a username of the form user@REALM is
923 specified and no password is specified, do not perform a
924 kinit operation. Only perform the aklog functionality.
926 * Add a new registry value which allows the number of processors
927 on which afsd_service.exe executes to be restricted. Valid
928 values are 1..numOfProcessors
930 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
934 * A second MSI based installer option is now available.
936 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
937 request tickets for user/instance@REALM instead of just user@REALM
939 * Modify the Power Management Notify routine to wait for the Hard Dead
940 timeout period instead of a fixed 19 seconds. With the longer timeout
941 periods Hibernation and Standby could never succeed when network
942 connectivity is not available.
944 * The following fs.exe commands are now restricted to Administrator:
945 - checkservers with a non-zero timer value
948 - sysname with a new sysname list
957 setting the default sysname for a machine should be done via the
958 registry and not via "fs sysname".
960 * NSIS installer adds options to install Debugging Symbols
961 and the Microsoft Loopback Adapter; the user is now also
962 given the ability to select the afscreds.exe startup options.
964 * Build system modified to generate symbols for FREE (aka RELEASE)
965 builds as well as CHECKED (aka DEBUG) builds
967 * Sites which have a volume ID of 0x20000001 assigned to their
968 root.cell volumes have been experiencing problems with accessing
969 the root.cell volume of their cell when Freelance mode has been
970 active. This was because 0x20000001 was assigned to the fake
971 root.afs volume created by freelance. The fake volume id is
972 now set to 0x00000001 to prevent conflicts.
974 * The timeout logic in the AFS Client Service has been wrong
975 for sometime. It is based on two different assumptions.
976 First, the SMB client timeout is a fix value as was the case
977 with OS/2 Lan Manager. This assumption is incorrect. The
978 SMB timeout in Windows is a dynamic value computed based upon
979 a fixed minimum timeout to which is added time based upon the
980 size of the request and the performance characteristics of
981 the connection. Second, it is the responsibility of the
982 SMB Server to enforce the timeout requirements of the client.
983 This is untrue. The SMB Server cannot be expected to know
984 the requirements of the client. More importantly, if the
985 SMB server uses the SMB client timeout as a value to restrict
986 its behavior as an RX client, the performance characteristics
987 of the local SMB session would be used to prematurely terminate
988 WAN connections with significantly different performance
991 The timeout logic has therefore been modified in the following
993 . the Lan Manager Workstation (SMB) Session Timeout is used only
994 as a basis for configuring the Connection Dead Timeout
995 and Hard Dead Timeout values. The Connection Dead Timeout
996 must be at least 15 seconds longer than the SMB Timeout
997 and the Hard Dead Timeout must be at least double the
998 Connection Dead Timeout.
999 . New registry entries have been added to allow the Connection
1000 Dead Timeout and Hard Dead Timeout values independent of the
1001 Lan Manager Workstation Session Timeout
1002 . The test to enforce the SMB Client Timeout has been removed.
1004 One of the side-effects of removing the enforcement of the SMB
1005 Client Timeout is that regardless of whether or not the SMB client
1006 is available to receive the response (and how would the SMB server
1007 know) the RX protocol response can be used to update the AFS
1008 Client Service state for ready access by future SMB client
1011 This should be the end of the "Server paused or restarting messages"
1013 * Add support for arbitrary UNC paths to the pioctl() support.
1014 This enables the fs commands as well as the AFS Shell Extension
1015 to work correctly when UNC paths are being used.
1017 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1018 DNS if the cell configuration cannot be determined via CellServDB
1020 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1021 are ever set more than once at a time
1023 * Fix the management of lists of cm_cell_t structures when using
1024 DNS to lookup cell information. The previous code would fail to
1025 reuse the same cellID for a cell if DNS was used more than once
1026 for a given cell name. When the ttl expired, a single cm_cell_t
1027 could be inserted into the cm_allCellsp list more than once
1028 producing a loop. In addition, the vlServerp list belonging to
1029 the cell was not freed resulting in improper refCounting of the
1032 * Add DNS support to cm_IoctlNewCell() which previous only examined
1035 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1036 to properly garbage collect cm_server_t objects
1038 * Add numVCs variable to smb.c to track the number of smb_vc_t
1039 objects created and use it to initialize the vcID field which
1040 previously was set to 0 in all objects resulting in FindByID
1043 * Fixed DNS lookups to work consistently throughout the OpenAFS
1044 product instead of just from within the afsd_service.exe
1046 * Added a runtime check to ensure that AFS Client Service SMB
1047 Server is accepting connections before attempting to mount
1050 * Read IP addresses for volume servers out of the CellServDB
1051 file if gethostbyname() on the hostname fails.
1053 * Fix getcellconfig() to populate both the Hostnames as well
1054 as IP addresses when loading cell data via DNS
1056 * Increase the Connection Dead Time to 50 from 20 seconds
1057 Increase the Hard Dead Time to 120 from 40 seconds
1058 (matches the Unix values)
1060 * Fixed an assertion validating the number of allocated NCBs
1062 * Fixed the build environment to consistently build for
1063 Windows 2000 and above. (APPVER = 5.0)
1065 * Fixed rx_debug to properly validate the receipt in incoming
1066 data with select() and recvfrom(). Do not copy data out of
1067 the socket buffer unless success is indicated.
1070 * afsd_service.exe will now display a message box to the
1071 desktop when it terminates due to an IP Address Change.
1073 * installer no longer deletes AFS Server configuration data
1076 * installer generates a warning dialog if the RPC service
1077 is not properly configured
1079 * installer compressed with lzma instead of bzip2
1081 * afsd_service.exe shutdown crash solved once and for all
1083 * reference counting of smb_vc_t data structures improved
1085 * name space collision of smb_fid_t event objects corrected
1087 * the output of "fs memdump" is now written to
1088 %WINDIR%\TEMP\afsd_alloc.log
1090 * the file TaAfsApp_1033.dll is now properly installed allowing
1091 the User Manager to start
1093 * a new algorithm is used for computing filename pattern matches
1095 * afscreds.exe now accepts user names containing instance
1098 * Fix the Directory Name Lookup Cache to be case-sensitive.
1099 This is crucial in environments in which a Windows client
1100 is accessing a directory with more than one filename that
1101 differs only by case. If the directory contains "FOO"
1102 and "Foo". You want "DEL Foo" to delete the correct one.
1103 We still have a problem in that "DEL foo" will delete a
1104 random filename. This will be addressed in a future release.
1106 * Fix afscreds.exe -M option (renewMaps) to work when High
1107 Security mode is off. Also, remember to disable the ActiveMap
1108 flag in afsdsbmt.ini when a drive mapping is removed.
1110 * Updates to NSIS installer script. AFS Server configuration
1111 data will not be destroyed on un-install or re-install.
1112 Use a better compression algorithm.
1114 * afslogon.dll now uses KFW to obtain tokens when available
1116 * afslogon.dll when given an all uppercase username will
1117 attempt to authenticate with both the uppercase name
1118 and an all lowercase variation
1120 * DST modification removed. The fix appears to make things
1121 worse after a reboot of the machine.
1123 * fs.exe: added "cscpolicy" which is used to
1124 change client side caching policy for AFS shares
1126 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1127 [-documents] [-disable] [-help]
1129 * Several uninitialized variables have been initialized
1131 * It is now possible to obtain tokens using cross realm
1132 Kerberos within afscreds.exe:
1134 user: jaltman@ATHENA.MIT.EDU
1136 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1137 will will in turn be used to obtain afs@DEMENTIA.ORG.
1138 The resulting token will be stored with the display name
1139 jaltman@ATHENA.MIT.EDU@dementia.org
1141 * aklog.exe has been added to the client
1143 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1144 [[-p | -path] pathname]
1148 -d gives debugging information.
1149 krb_realm is the kerberos realm of a cell.
1150 pathname is the name of a directory to which you wish to authenticate.
1151 -noprdb means don't try to determine AFS ID.
1152 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1153 (default is Kerberos V)
1154 No commandline arguments means authenticate to the local cell.
1157 * All of the resource files have been restructured to adhere to
1158 a set of rules IBM implemented for loading string resources.
1159 These rules had either been forgotten or were not discovered
1160 by folks working on the OpenAFS sources. The end result was
1161 memory corruption. This is primary item which was preventing
1162 the AFS Server from working.
1164 * Increased the size of the maximum ticket size stored in a token
1165 from 344 bytes to 12,000. Increased the buffers used to convey
1166 messages between the pioctl() caller and the SMB Server from
1167 1000 bytes to 12,512. The code appeared to have been writing
1168 above the top of the stack by quite a few number of bytes.
1169 (The increased ticket size is necessary for the next item.)
1171 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1172 Instead the raw Kerberos 5 ticket is used in its entirety. This
1173 is extremely important as it allows us to use pure Kerberos 5 KDCs
1174 as the source of the AFS authentication. The use of up to 12,000 byte
1175 tickets will allow tickets produced by all versions of Microsoft
1176 Active Directory to be used.
1177 - create a user account.
1178 - designate it DES only
1180 - specify its UPN to be "afs@realm"
1181 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1183 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1184 is special when using long file names. (you must use "*.*" and not "*")
1185 Instead only enforce it when performing 8dot3 searches.
1187 * Fixed the DST problem with creation times being set one hour ahead
1189 * Fixed the problem when using \\afs\cell-alias. For example,
1190 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1191 for the alias name; instead simply expand the name. One of the
1192 symptoms of this problem was a loss of acquired tokens.
1194 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1195 of strings. (Only English strings provided.)
1197 * Fixed the installer to properly replace in use files.
1199 * Fixed the build system to cleanup generated component version files
1201 * The release build compiled with MSVC 6.0 compiler to avoid the
1202 afsd_service.exe shutdown crash. This does not solve the problem
1203 but simply avoids it for the time being.
1207 * fix afslogon.dll to not corrupt memory when High Security mode
1210 * fix afsd_service.exe to not attempt to restore the stack when
1211 an exception occurs. (not safe in multi-threaded programs)
1213 * fix uninstaller to properly remove the CRT and MFC DLLs
1215 * remove a Message Box from afscreds.exe when getcellconfig()
1216 fails on a kerberos realm which is not a cell
1218 The following is a list of changes to the OpenAFS for Window client
1221 * "fs setserverprefs" will leave afsd service deadlocked
1223 * "vos listaddrs" will core dump
1225 * installer sets the appropriate keys to support Integrated Logon
1227 * installer disables the "Find Lana by Name" functionality as it
1228 was causing headaches for many users
1230 * fix the intermittent crash of the power management thread when
1231 shutting down the AFS Client Service
1233 * optimizes the obtain drive mount list functionality which is
1234 executed every time the mount tab in afscreds.exe and afs_config.exe
1235 are refreshed. (this happens a lot)
1237 * fix the service shutdown logic. add the STOP_PENDING state
1238 and do not accept additional service events after we declare
1241 The following is a list of changes to the OpenAFS for Window client
1244 * flexelint was run against the source tree and hundreds (perhaps
1245 thousands) of corrections were applied to ensure prototypes
1246 were in use; types were used consistently; variables were
1247 initialized; unused variables were removed; etc.
1249 * A wide variety of instrumentation was added including the
1250 ability to produce a stack trace from within afsd_service.exe
1253 * Dynamic configuration of the RDRtimeout value based upon the
1254 LanMan Workstation Session Timeout
1256 * The mount root no longer needs to be called "/afs". This
1257 is now set by a registry value "MountRoot" within the key
1258 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1260 * The cell list is now only read out of afsdcell.ini when the
1261 file changes instead of each time a cell is resolved.
1263 * Thread synchronization was added to cm_server.c and ktc_nt.c
1265 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1266 calloc()/free(). The Global functions were needed on Windows 3.x
1267 but have caused a variety of problems on the Win32 platforms.
1268 Avoiding them is highly recommended by several Microsoft
1269 Knowledgebase articles
1271 * Support for Symbolic Links added to the AFS Shell Extension
1273 * Added a registry value "OverlayEnabled" to determine if
1274 Shell Extension Overlays should be enabled.
1275 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1277 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1278 separate trees for checked and free builds. Build system supports
1279 a custom directory src\WINNT\extra which can be used as a grafting
1280 location of organization specific additions to the build tree.
1282 * New installer built using NSIS 2.0.
1284 * Named all kernel objects in order to allow them to be monitored
1285 with tools such as SysInternals' ProcExp.exe.
1287 * Introduced new EventLog framework for AFSD
1289 * Introduced Power Management interface to AFSD for Standby and
1290 Hibernate modes to allow cache to be flushed prior to network
1293 * Utilize Win32 DNSQuery API instead of internal routines. This
1294 allows DNS SRV queries to be sent to all current domain name
1295 servers. Not just one specified in an INI file. DNS is now
1298 * "NetbiosName" registry value may be used to specify a fixed
1299 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1300 when the loopback adapter is in use. If you need to use the
1301 old notation with a loopback adapter installed specify a registry
1304 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1306 * Refactor all modules which depend on LAN Adapter and NetbiosName
1307 determination in a new library: lanahelper.lib. This allows for
1308 consistent behavior throughout the product.
1310 * Move the afsd.log and afsd_init.log files to the directory specified
1311 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1312 for services. Added the Date to the log entries.
1314 * New registry value "RxMaxMTU" used to limit the size of the RX
1315 packets sent by the AFS Client Service to the Server. In order
1316 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1317 size must be restricted to 1264 or smaller. The latest NSIS
1318 installer sets a value of 1260 by default.
1320 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1321 packets. This is not needed in order to work across the Cisco
1322 VPN but might be needed for other network environments. This
1323 value is not set by the NSIS installer.
1325 * New registry value "HideDotFiles" is used to apply the Hidden
1326 attribute to files whose names begin with a '.'. This value
1327 is set by the NSIS installer.
1329 * New registry value "MaxMpxRequests" allows the maximum number
1330 of multiplexed sessions to be configured at run time. This
1331 value is not set by the NSIS installer. The default value is
1334 * New registry value "MaxVCPerServer" allows the maxmimum number
1335 of VCs per server to be configured at run time. This value is
1336 not set by the NSIS installer. The default value is 100.
1338 * New registry value "AllSubmount" allows the "all" submount to
1339 be disabled by setting its value to 0x00.
1341 * Allow cells names to be valid mount points
1342 \\<netbiosName>\<cellname>
1344 * Store the active state of drive mappings in order for afscreds.exe
1345 to restore them upon startup
1347 * Add exception handling to generate a Stack Trace to the afsd_init.log
1348 file if one happens to occur.
1350 * Add lots of logging to help detect the cause of invalid SMB packets
1352 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1353 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1354 renewal of expiring tokens as long as afscreds.exe is running.
1356 * New afscreds.exe command line options:
1358 -M = renew drive maps
1359 -N = ip address change detection
1362 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1363 determines whether or not MIT Kerberos for Windows should be used
1364 to obtain tokens via Kerberos 5 tickets.
1366 * New registry value "AfscredsShortcutParams" in
1367 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1368 determines the command line parameters to be specified when "fixing"
1369 the AFS Shortcut in the user's startup folder.
1371 * The "ShowTrayIcon" registry value has been moved from
1372 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1373 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1375 * The <cell name> registry values used to store the token expiration
1376 reminders have been moved from
1377 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1378 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1380 * Obtain the Logon User Name from the Explorer key when available
1382 * new text document doc\txt\winnotes\registry.txt lists all registry
1383 values used by OpenAFS (excluding the AFS Server)
1385 * BUG: rx_securityClass objects were not properly reference
1386 counted and were never freed.
1388 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1389 would be generated. The existence of a server does not imply
1390 that it is not down. If all of the servers for a cell are down
1391 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1394 * BUG: the directory name lookup cache failed to free the entries
1395 in the cache when the name cache entries cycled. The entries
1396 in the cache would become dereferenced without being freed.
1398 * BUG: fs setserverprefs could be executed without Administrator
1401 * BUG: the number of allocated NCB objects (100) exceeded the number
1402 which could actually be waited upon by the kernel (64). Any objects
1403 which were utilized above the limit could never have event completions
1406 * BUG: smb_username_t objects were not being reference counted and
1407 were not properly freed.
1409 * BUG: smb_tid_t objects could under unusual circumstances be freed
1410 before they were no longer referenced.
1412 * BUG: smb_fid_t object pointer were frequently used even when
1413 their value could be NULL. They were not properly released and
1414 therefore they were never freed.
1416 * BUG: smb_packet_t data structures were not completely initialized
1419 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1420 Denied" because that causes the Explorer Shell to try again until
1421 access is obtained. Instead return "Remote Resources" which allows
1422 the shell to move on and treat the error as transient.
1424 * BUG: when initializing the NCBreturns structure, separate Event objects
1425 were created for each NCB although a single Event object was supposed
1426 to be shared by all.
1428 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1431 * BUG: smb_tran2Packet_t objects were not being properly referenced
1434 * BUG: directory path creation did not handle the case of multiple
1435 directories requiring creation in one attempt
1437 * BUG: SMB requests which required an Extended Response were ignored.
1438 This prevented some files from being written to AFS volumes.
1440 * BUG: character strings were being freed even after they were
1441 inserted into in use data structures
1443 * BUG: inconsistent usernames were used when High Security mode was
1444 enabled. (there is still much to do in this area)
1446 * BUG: pioctl() calls which require out of band RPC operations were
1447 susceptible to race conditions when performed by multiple processes
1449 * BUG: memory allocation and deallocation crossed instances of the
1450 C Runtime Library producing memory leakage and corruption in
1451 afscreds and the client configurator.
