2 * Windows Crash Reporting does not get triggered for afsd_service.exe
3 because it provides its own top level exception handler. This patch
4 places an explicit call to ReportCrash() on platforms which support
7 If you configure Crash Reporting via AD Policy to capture crash
8 reports within the domain, then you will receive this output.
10 * Generate MiniDumps independent of the Windows Crash Reporting.
12 (a) If an exception occurs,a minidump will be generated at the path
13 %TEMP%\afsd.dmp. The type of minidump defaults to Normal but
14 can be set to any other type via use of the
17 [HKLM\SOFTWARE\OpenAFS\Client] MiniDumpType (DWORD)
19 (b) MiniDumps can be generated at any time using the "fs minidump"
20 command. This allows you to generate a minidump without
21 stopping the process or even requiring the use of a debugger
24 * an RX connection which reports bad ticket now treats it the same way
25 the expired ticket is treated. The ticket is removed from the
26 connection and a new anonymous connection is established.
28 * fs memdump now requires that the caller be in the AFS Client Admins
31 * additional debugging information is provided in cm_Analyze when the
32 error code is ignored.
34 * Fix a regression introduced into the pioctl() client code which
35 will cause a crash in winlogon.exe, explorer.exe and fs.exe if
36 MIT KFW is not installed. (1.3.82a)
38 * Remove AFS Gateway option from OpenAFS Control Panel (1.3.82a)
41 * Fix a race condition in cm_EndCallbackGrantingCall() that
42 could leave 'nrevp' pointing to freed memory. In the process,
43 optimize the processing to ensure that the applications monitoring
44 the status of the stat cache entry are only notified at most
47 * Conditionalize access to the Explorer Shell AFS->Mount Point
48 ->Remove menu item. Disable the item if the selected item(s)
51 * Activate AFS RPC (RX) Free Packet Queues stored in Thread
52 Local Storage. This eliminates thread contention on the
53 global RX free packet queue. This should improve performance
56 * Fix the IP address filtering code to properly load/unload
57 the IPHelper DLL so that Windows XP/2003 and beyond systems
58 do not have to manually probe the registry.
60 * CleanupACLEnt() was not being called consistently with
61 the cm_scache_t object referred to by the back pointer
62 mutex locked. This could in very rare conditions lead to
63 an invalid memory access.
65 * Added a script command to the msi installer "afs_replace"
66 which can be used to replace one version of OpenAFS with
67 another without requiring an uninstall and reinstall if
68 the installed msi is no longer in its original location.
70 * Apparently the problem with multi-domain forests with cross-
71 realm trusts to non-Windows realms was not entirely solved.
72 The authentication to the AFS SMB service failed because
73 the wrong name was being used. Using ASU as an example,
74 the authentication was being performed with the name
75 "QAAD\user" (an account in the forest root) and not
76 "user@ASU.EDU (the MIT Kerberos principal used to login with)
78 The solution was to add an additional dependency on KFW
79 in order or to be able to easily obtain the client principal
80 name stored in the MSLSA ccache TGT. This information is
81 used in two locations:
83 - the pioctl() function
85 - a new WinLogon Event Handler for the "logon" event.
87 The pioctl function will now be able to use the correct
88 name when calling WNetAddConnection2() and the "logon"
89 event handler will now be able to call WNetAddConnection2().
90 The hope is that the "logon" event handler will be called
91 before the profile is loaded but I have not guarrantee
95 * Fixed a locking error in cm_TryBulkStat() which had the
96 potential of deadlocking the system for the length of time
97 it takes to perform a bulk status fetch operation.
99 * Replaced time conversion code (UnixTime <-> FILETIME) to
100 be completely arithmetic instead of relying on a bizarre
101 algorithm involving a variety of C RTL time functions.
102 This has the side effect that UnixTime and FILETIME which
103 are both stored in UTC are interpretted as UTC throughout
104 the year. Windows will apply the same localization to AFS
105 as it does to NTFS. Applications which rely on the ability
106 to sync files between the two file systems will no longer
107 see the timestamps of files in AFS change an hour relative
108 to the files stored in NTFS or Windows based backup devices.
110 * Fixed a invalid memory access under a bizarre circumstance.
111 Windows will allow a physical mass media device to be
112 installed via Plug N Play to the system and will assign it
113 the lowest available drive letter. This is true even if the
114 drive letter is currently assigned in the user session to
115 a network device via NET USE (or its equivalent.) When this
116 happens, queries sent to the CIFS server will contain invalid
117 data. This invalid data was not being caught by the AFS
118 Client Service and was resulting in a crash when Freelance
121 * Fixed a reference count error when registering callbacks
122 on a stat cache object if the callback was already registered
124 * Add a case to cm_Analyze() in order to handle the case where
125 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
126 the server list for the volume is empty. In this case, force
127 an update of the volume info and retry.
129 * Insert a missing cm_EndCallbackGrantingCall() which could
130 result in threads waiting for a callback to complete to never
133 * In the persistent cache, there is a maximum number of volume
134 entries. Allow volume entries to be reused if the maximum
135 number have been allocated and their reference count is zero.
137 * If we already have a dead virtual connection object, don't
138 ignore the fact that additional dead vc objects must be taken
141 * Removed a deadlock condition introduced in the summer of 2004.
142 Do not hold mx locks around calls to RX functions including
143 rx_NewCall(). That is what reference counts on the rx_connection
146 * Fixed an initialization error in afslogon.dll which could
147 result in random behavior including a failure to terminate
148 the NPLogon function. (1.3.80b)
150 * Fixed an error preventing the use of SMB authentication
151 on Windows 2000. (1.3.80a)
154 * Updated CellServDB to Public CellServDB 16 Mar 2005
156 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
157 misinterpretted as "csail.mit.edu" when the resolver
158 is configured to append ".mit.edu" to failed DNS queries.
160 * Fixed another case in which the client would replace connections
161 to the host when it was not necessary. In this case the
162 situation would occur if cryptall was on and the connections
163 were unauthenticated due to lack of an appropriate token.
165 * OpenAFS for Windows has failed to work at sites which are
166 utilizing a cross-realm trust between an MIT/Heimdal realm
167 and a multi-domain Windows forest when the workstation being
168 accessed is not located in the root domain. This is caused
169 by a bug in the workstation which was triggered after the
170 introduction of Windows 2003 Server. When the bug is triggered,
171 the workstation attempts to authenticate users to afsd_service.exe
172 by contacting the Domain Controller instead of using the
173 LSA loopback authentication mechanism.
175 One of the reasons this bug occurs is because the workstation
176 does not have a reliable way of knowing that the service whose
177 netbios name is "AFS" is located on the workstation. This will
178 be fixed starting in Longhorn Beta 1 by Microsoft. The
179 "BackConnectionHostNames" registry value will be used to
180 indicate that the authentications to that service name should
181 be performed using the loopback authentication mechanism.
183 In the meantime, when Logon Caching is enabled, we can force
184 afsd_service.exe to authenticate using the logon cache before
185 contacting the Domain Controller. This will work with both
186 password and smart card based logons.
188 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
189 flag should not be cleared if a volume's server reference is
190 marked as "offline". In the case where all of the volume's
191 servers are either "down" or the volumes are "offline", we want
192 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
193 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
194 should never occur in practice.
196 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
197 5 seconds, clear the server down and volume busy flags, and
198 then force an update from the VLDB. This allows the client to
199 update the location of a volume if the reason for it being
200 marked offline is because it is being moved. Calls to
201 cm_ConnByMServers() will be retried either until success or
202 the RDRtimeout period is reached.
204 * Correct the Power Management code behavior in response to
205 Standby, Suspend, and Shutdown events. Instead of flushing the
206 buffers associated with the mounted SMB submounts, simply write
207 all buffers which are marked dirty.
209 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
210 provides a list of cells other than the default cell for which
211 tokens should be obtained using the default Kerberos principal.
212 This functionality is logon domain specific and is only available
213 when using KFW for authentication.
215 * Fixed FindNext Invalid Handle error caused by over agressive
216 attempts at garbage collecting dirSearch entries when the
217 dirSearch ID wraps from the maximum value to 1.
219 * Add support for registry defined server preferences for VLDB and
220 File servers. See registry.txt for details.
222 * Increased default cache size to 96MB and default number of cache
225 * Fixed refCount leaks related to directory lookups and pioctl calls.
227 * Callbacks revoked during a race condition with an attempt to
228 obtain the same callback no longer result in an inaccessible
231 * New command line tool:
233 afsdacl : Set or reset the DACL to allow starting or stopping
234 the afsd service by any ordinary user.
236 Usage : afsdacl [-set | -reset] [-show]
238 -reset : Reset the DACL
239 -show : Show current DACL (SDSF)
241 * IP addresses are no longer queried once at startup. Instead IP
242 addresses are obtained as needed. Loopback adapter addresses are
243 no longer published to the server.
245 * Pay attention to the MIT KFW registry configuration for automatic
246 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
248 * Fix (once again) case-sensitive comparisons which was apparently
251 * Activate support for vos listvol -format
253 * Population of the "AFS Client Admins" group failed on non-English
254 versions of Windows because the name of the "Administrators" group
255 is localized. Now we lookup the name of the group by using the
256 Administrators Group Alias Relative ID.
258 * Multiple cell token acquisition within afscreds.exe was broken in the
259 case of Kerberos 5 cross realm authentication. Instead of contacting
260 the KDC associated with the cell's realm, afscreds would obtain a
261 token from the KDC of the user's realm. This would result in
262 "invalid kvno errors" while authenticating to the AFS servers.
263 Unauthenticated access would work. The symptoms would vary based upon
264 whether or not the VLDB servers had been contacted using unauthenticated
265 connections prior to the user obtaining tokens.
267 * The list of ACL entries was becoming corrupted. It appears as if
268 an ACL when it expires was not being appropriately cleaned up. In
269 fact, it was left in the list of ACLs associated with the scache
272 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
273 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
274 and "amd64_win64" for amd 64-bit processors.
276 * When executing executables, Windows provides a mechanisms by which
277 the normal search for DLLs can be bypassed. If a file foo.exe is
278 being executed and there exists a file or directory "foo.exe.local"
279 (the contents are ignored if a file), then Windows will search for
280 DLLs first in the "foo.exe.local" directory and second in the
281 directory in which the "foo.exe" file is located.
283 Previous releases of OAFW would improperly return
284 STATUS_NOT_A_DIRECTORY instead of the expected
285 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
286 to terminate the search for the DLL causing the execution of the
289 * Rework the reference counting of smb_vc_t objects. The references
290 stored in the waiting locks were not counted. This could result in
291 an assertion if the reference count drops to zero.
293 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
294 when running in freelance mode.
296 * Added support for persistent caching of file contents, stat entries,
297 volume data, cell data, and name lookup data. When the registry
298 value, "NonPersistentCaching", is not defined or set to 0 the file
299 specified by "CachePath" becomes a persistent cache file. The
300 size of the cache file is computed at run time. It has a maximum
301 size of approximately 1.2GB. The contents of the file will be
302 validated according to the rules specified by the "ValidateCache"
305 * Added support for UUIDs. UUIDs are kept for as long as the
306 cache file is intact.
308 * Added cmdebug.exe and support cache manager debugging callback
309 interfaces in afsd_service.exe.
311 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
312 [-addrs] [-cache] [-help]
313 Where: -long print all info
314 -addrs print only host interfaces
315 -cache print only cache configuration
317 * Symlinks to \\AFS\[all\]... will now be treated the same as
318 symlinks to /afs/.... However, please use /afs/... as otherwise
319 the symlinks won't work on Unix.
321 * Correct a problem with local CellID allocation for cells whose
322 server list is obtained via DNS instead of a CellServDB file. If
323 the DNS information expires the CellID assigned to the entry will
324 be changed. This causes all of the cm_scache_t objects which refer
325 to the old cellID number to become useless. Attempts to access
326 files or directories with cm_scache_t objects using the old cellID
327 will fail since the server list cannot be obtained.
329 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
330 be triggered if the volume referenced by the cm_scache_t object is
333 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
334 in addition to SERVICE_ACCEPT_STOP.
336 * Move RPC shutdown until after the SMB and RX shutdown procedures
337 complete. Block until RPC shutdown is complete.
339 * Modify afslogon.dll (integrated logon) to wait for service if its
340 state is START_PENDING. If the timeout period occurs, reset to
341 the retry interval and not the sleep interval.
343 * When renewing the server list for a cell obtained via DNS AFSDB
344 records, the cm_cell_t entry must be removed from the list of all
345 cells. Otherwise, the list of cells will be corrupted.
347 * In the dcache and scache modules, use the cm_scache_t dataVersion
348 instead of the cm_fakeDirVersion.
350 * Synchronize fs.c with the unix version.
352 * The variable used to determine whether a file or virtual memory
353 mapped cache is used was not properly initialized to a default
354 value. If the registry setting "NonPersistentCaching" was not
355 set, the choice would be random. Properly initialized to be
358 * The memory mapped view was never unmapped before closing the file
359 at service shutdown. This is now properly cleaned up.
361 * Default location of Cache file is now %TEMP%\AFSCache
365 * A bug affecting new installations of 1.3.75/76 would result in
366 the creating of incorrect mountpoints in the freelance root.afs
367 volume for the default cell.
369 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
370 of "root.cell", you have been affected by the bug. To correct the
371 problem, execute the following commands:
373 fs rmmount \\afs\all\<cellname>
374 fs rmmount \\afs\all\.<cellname>
376 fs mkmount \\afs\all\<cellname> root.cell <cellname>
377 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
381 * A bug has been fixed in the auto-generation of Freelance root.afs
382 symlinks which produced random entries in the \\AFS\all directory.
384 * Support has been added for multi-homed servers
387 * Added a new registry value, "StoreAnsiFilenames", which can be used
388 to force the use of ANSI character sets instead of OEM Code Pages.
389 This feature is useful when users require the ability to create
390 filenames with 8-bit characters and need to access the files from
391 both Latin-1 based Unix systems as well as from Windows.
393 Activation of this feature will prevent access to files stored with
394 8-bit OEM characters.
396 * Shutdown all SMB threads in a synchronized manner when stopping the
399 * There is currently a maximum cache size of 1.3GB. The limit is imposed
400 by the largest contiguous block of unused memory within the 2GB process
401 space which can be assigned to the memory mapped file. Unfortunately,
402 when the executable digital signature verification code is activated
403 Windows sees fit to further segment the process memory which in turn
404 reduces the size of the maximum cache file to less then 800MB. If
405 larger cache sizes are desired, a new registry value should be set:
407 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
409 Setting this value will disable the runtime verification of digital
410 signatures on afsd_service.exe and the afs dlls which it loads. It
411 will not disable the the version number check on those same files.
412 The signature verification is not a security messure and is only meant
413 to enhance the ability to afsd_service.exe to detect potential
414 destablizing mixtures of DLLs from incompatible distributions.
416 Added code to auto-disable the signature verification check if
417 the desired cache size is greater then 700MB.
419 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
420 used to verify the validity of the afsd_service.exe binary
421 as well as each of the AFS DLLs loaded by the service. Not only
422 must the digital signature be valid but the signatures of the
423 DLL must be signed by the same entity as the service.
425 * Implement new functions: cm_freelanceMountPointExists and
426 cm_freelanceSymlinkExists. Use them along with other validity
427 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
428 ensure that name collisions do not occur and that empty strings
429 are not valid file names.
431 A symlink may not have a name which would resolve to a valid
432 cell name. Doing so would prevent access to the cell.
434 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
435 re-initialization code. The reference counts of the fake root.afs
436 volume scache object(s) would become invalid when the mount point
437 or symlink lists were altered.
439 * Add registry entries to provide mappings from the afsdsbmt.ini
440 to the new locations for applications which count on the use
441 of the old Profile file APIs. These apps are likely to fail
442 if the user does not have administrator privileges and the
443 registry is locked down.
445 * The afs_config.exe submounts dialog had two errors.
446 First, attempts to remove entries failed because the registry
447 key was being opened without KEY_WRITE privileges.
448 Second, when editing a submount entry, changing the name
449 would add a new key and leave the original one in place.
450 Now the original submount will be removed if its name is
453 * In recent months there have been several incidents in which
454 users have experienced problems starting or accessing
455 afsd_service.exe and after significant effort has been spent
456 it has turned out that they have two versions of AFS on the
457 machine or an inconsistent set of DLLs.
459 Code has now been added to afsd_service.exe which will walk
460 the list of modules loaded by afsd_service.exe and validate
461 that the version of the AFS DLLs matches the version of the
462 afsd_service.exe executable. If they do not match the service
465 * When Freelance mode is enabled and there is no registry
466 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
467 will attempt to import the afs_freelance.ini file contents.
468 If the file does not exist, it was creating a dummy file
469 with a r/o and r/w entry for the default cell and then
470 importing those values.
472 This process has been changed. The temporary file is no
473 longer created. Also, both the OpenAFS Client install
474 directory as well as %WINDIR% are checked for previous
475 afs_freelance.ini files.
477 * Added support for VL_GetEntryByNameN(). Still need to add
478 support for VL_GetEntryByNameU() for multi-homed support.
480 * Fix a deadlock situation in afscreds.exe when canceling an
481 auto-generated Obtain Tokens dialog
484 * Fix the locking of objects during Directory Searches in the
485 SMB/CIFS server. The failure to properly lock the reference
486 counts was resulting in the premature freeing of smb_dirSearch_t
487 objects while they were still in use by the SMB/CIFS client.
488 This does not solve the "Invalid Handle" problem.
490 * Fix Find Cell By Name pioctl call to return a valid cell
491 name for the Freelance fake root.afs volume.
492 "Freelance.Local.Root".
494 * Fix the Explorer Shell Extension Symlinks->Add operation.
495 The dialog template was missing and the link destination
496 string was too short.
498 * Add support for symlinks to Freelance root.afs volume
499 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
500 <number> = "<linkname>:<relative-path>."
501 Use symlink.exe to create, list, or remove
503 * Remove the fallback to the use of KFW's KRB4 library when obtaining
504 tokens. We never obtain KRB4 tickets.
506 * Fix AFS Client Configuration Control Panel to support new SysName
509 * Fix a bug in afsd_service.exe which could result in the SysName
510 not being read from the registry.
513 * Add code to block the issuance of AFS tokens by aklog.exe or
514 afscreds.exe when the Kerberos 5 principal name contains a dot.
516 * Modify the IsAdmin() function to always treat the local SYSTEM
517 account as an AFS client administrator. Affects fs.exe and
520 * Modify the internal handling of Quota Exceeded errors
522 * Upgrade all reference count fields in the Windows cache manager
523 and the osi library to use unsigned long instead of signed short.
524 A similar fix has been applied to the afs rpc (rx) library.
526 * fix the Windows cache manager to prevent it from replacing the
527 rx_connection object associated with the cm_conn_t object on each
528 and every operation if "fs crypt" was set. This explains the
529 dramatic performance difference when crypt is used vs clear.
530 The problem: 'cryptall', a boolean flag indicating whether or not
531 "fs crypt" is set, was being compared to the rx_connection
532 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
533 1 != 2 and therefore the rx_connection was always destroyed
534 and replaced on each and every operation.
536 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
537 It is not safe for the cm_conn_t object to not be locked because
538 rx_DestroyConnection might be called from another thread if:
539 - the user's tokens have changed or expired
540 - the crypt mode has changed
542 This fix appears to have also taken care of the problems associated
543 with Overlapped Writes resulting in Delayed Write errors.
545 * fix NSIS installer's AdminGroup.exe to properly create and
546 remove groups when given -create or -remove. The string comparison
549 * fs sysname now accepts a list of sysname values
551 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
552 DWORD which when set to a non-zero value will cause error message
553 text to be output to stderr from the pioctl() routine. Useful in
554 debugging failures of fs.exe, tokens.exe, etc.
556 * added a test to the power management code to only perform a
557 flush operation if there is at least one network adapter which
558 is not a loopback adapter.
560 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
561 "EnableKFW". This value will not be read if the key
562 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
563 value under that key does not.
565 * provide mechanisms to force the use of krb524d for Kerberos 5
566 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
567 there is a new registry value "Use524" and for aklog.exe a new
568 command line parameter "-m".
570 * Fix the pattern matching algorithm to properly match patterns
573 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
574 which is used by both the original function and the new
575 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
576 creation of HardLinks in addition to Renaming. smb_Link()
577 is a new function which creates HardLinks via cm_Link().
578 cm_Link() is a new vnodeops function which creates links
581 smb_ReceiveNTRename() does not support the File Copy and
582 Move Cluster Information operations described in its interface.
583 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
585 * When opening files via symlinks, we should follow the symlinks
586 until we reach the actual file stat cache entry. The stat cache
587 entry of the file should then be stored in the FID instead of
588 stat scache entry of the symlink.
590 * return bad operation errors for all unimplemented functions
591 even if we do not know the functions exist.
593 * Log bad packets and unknown operation packets to the trace log
595 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
598 * Update list of known CIFS operations to include all those listed
599 in CIFS-TR-1p00_FINAL.pdf.
601 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
602 to support the REG_EXPAND_SZ type.
605 * A new Windows authorization group "AFS Client Admins" is now
606 created and populated with the members of the "Administrators"
607 group. The group is used to determine which accounts on the
608 machine may be used to modify the AFS Client Configuration via
609 the UI and command line tools. afs_config.exe, fs.exe,
611 * Modify the WinLogon Logoff Event Handler to query NT4 domain
612 controllers for the remote profile path if Active Directory
613 services are not available.
615 * Fix aklog.exe to not add the AFS ID to the username
617 * PTS registration of new users to foreign cells has been added to
620 * The cm_Daemon thread is used to perform checks for
621 down servers, up servers, volumes, callback expirations,
622 lock maintenance and token expiration. Due to a gaff in
623 larger integer division the thread never performed any
624 work. Instead the current time computation would always
625 be less then the trigger times. This had an adverse affect
626 on the client's ability to maintain communication with servers,
627 keep volumes up to date, and flush user tokens and acls
628 when they have expired. This was broken when the 1.3 branch
629 was modified to support VC7 which no longer included
632 * An initialization problem with the Freelance code was
633 detected while fixing the callbackRequest. The cm_rootSCachep
634 object is obtained during afsd_InitDaemons() but the callback
635 information is incomplete. The callback information will not
636 be obtained until cm_MergeStatus is called from within
637 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
638 test for the conditions under which the callback information
641 * Reports have been filed indicating that callbacks were
642 being lost. An examination of the code indicated that the
643 cm_server_t objects were not being properly reference
644 counted by the cm_scache_t and cm_callbackRequest_t objects.
645 In particular, the cm_server_t objects may have been freed
646 from beneath the cm_conn_t objects.
648 All of the reference counting is now done via the functions:
653 this improves the ability to track the referrals.
655 Each cm_BeginCallbackGranting Call now allocates a reference
656 to the cm_server_t. The cm_EndCallbackGrantingCall either
657 frees the reference or transfers it to the cm_scache_t
658 cbServerp field. These are then appropriately tracked
659 through the cm_Analyze call.
661 * Ensure that the dnlc hash table is the same size as the
662 dir name hash table (as per original author's note).
663 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
664 for compatibility with 64-bit systems.
666 * fix smb_ApplyV3DirListPatches to properly apply the hidden
667 attribute to dotfiles when the infoLevel < 0x101 and
668 cm_SyncOp has failed.
670 * Fix the Freelance registry initialization code. There
671 was a possibility that some systems could end up with
672 garbage in the registry during a clean install.
675 * file and directory names beginning with "." will now be given the
676 hidden attribute when the volume access is anonymous. this matches
677 the behavior when the volume access is via an authenticated user.
679 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
680 key. When a change occurs mark the root.afs data as invalid and
681 for it to be reloaded on the next access. This allows administrators
682 to modify the mount point list without restarting the service.
684 The freelance client used to provide a fake modification time for
685 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
686 Added code to extract the last modification time of the Freelance
687 registry key and use that instead. The time now represents the
688 most recent mount point change.
690 * PTS registration of new users to foreign cells has been added to
693 * Additional Cache Control and Credential Manager options have been
694 added to the WiX installer. See deployment guide for details.
696 * The CachePath setting is now optionally a REG_EXPAND_SZ type
698 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
701 * The loopback installation code may have had a problem updating the
702 %ETC%\HOSTS file which could have resulted in a premature failure.
703 Work around code has been added for the case where the file cannot
706 * The default max chunksize was increased from 15 (32K) to 17 (128K)
707 because Windows sends 64K blocks when using overlapped writes.
709 * The default number of server threads was increased from 4 to 25 to
710 better handle overlapped writes.
712 * The "AfscredsShortcutParams" registry value was not being properly
713 loaded by afscreds.exe. Therefore, the default value was always being
714 used instead of the value set by the installer.
716 * Windows XP provides downgrade attack detection to prevent an attacker
717 from being able to force the use of NTLM simply by disrupting
718 communication with the KDC. This attack cannot exist between the
719 Windows CIFS client and the AFS Client Service. Therefore, when a
720 downgrade has been detected the afs pioctl library will force the
721 establishment of a new CIFS connection using NTLM.
723 * A locking error was discovered surrounding all references to volume
724 server lists within the cm_cell.c source file.
726 * The logged into Windows username was incorrect on Terminal Server
729 * A new registry value "NonPersistentCaching" was added to the service
730 parameters key. When set to a non-zero value, the afs cache is stored
731 in the Windows paging file. There are two limitations to choosing
733 1. when persistent caching is implemented it won't work with
734 this flag set since there will be nothing to persist.
735 2. with this flag set the initial paging allocation cannot be
736 changed while the service is running
738 * An initialization bug was discovered in aklog.exe which affected users
739 who have a domain name for their afs servers which could not be mapped
743 * afs_config.exe now validates cell names against DNS in addition
744 to the CellServDB file.
746 * In order to allow the freelance client to connect to a volume with ID
747 equal to 1 on the default cell we changed the fake root.afs volume ID
748 once again. This time we choose 0xFFFFFFFF. In addition, we change
749 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
750 It will now be impossible for a volume ID to match that of another
751 cell unless the client is connected to 0xFFFFFFFD cells. That should
752 be enough room for growth.
754 * Fix "fs mkmount" command to work with UNC paths and when
755 started from non-AFS drives. It is now possible to create a mount
756 point in the freelance fake root.afs volume with the command
758 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
762 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
763 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
765 * The algorithm used to re-attempt access to the servers associated with
766 a volume has been altered to properly address the case in which all
767 servers have been marked down. The previous algorithm did not reset
768 the server's down flags so the servers were never actually retried.
769 This caused a problem with active volumes if the network connectivity
770 was lost as could be the case with a network cable removal, wireless
771 drop, or laptop hibernation. With the fix volume access is restored
772 almost instantenously when network connectivity becomes available.
774 * Support for SMB/CIFS browsing has been added to the AFS Client Service
775 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
776 listing of AFS submounts and freelance mount points. Support for
777 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
778 significantly enhances the behavior of AFS volumes within the Explorer
779 Shell. For instance, "AFS" now shows up as server in the Explorer
780 with each submount or freelance mount point visible as a share.
781 The right click menu in each folder now works with full functionality
782 on a consistent basis.
784 * The network provider can be configured to have different behavior
785 depending on the domain that the user logs into. These settings are
786 only relevant when using integrated login. A domain refers to an
787 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
788 local machine (i.e. local account logins). The domain name that is
789 used for selecting the domain would be the domain that is passed into
790 the NPLogonNotify function of the network provider. (see registry.txt
793 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
794 "Authentication Cell" which may be used to specify a default
795 authentication cell for afscreds.exe which is different from
796 the default cell for the AFS Client Service daemon.
798 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
799 afslogon.dll moved to %WINDIR%\System32\.
800 New registry entries added to register the dll for Winlogon events.
802 The logoff event will now force a call to ktc_ForgetAllTokens()
803 using the context of the user being logged off as long as the
804 user's profile is not loaded from within AFS. If the profile
805 was loaded from AFS we can't release the tokens since the Logoff
806 event is triggered prior to the profile being written back to
807 the its source location. This is now performed in an XP SP2
810 * Windows XP SP2 Internet Connection Firewall interoperability
813 * The %WINDIR%\afsdsbmt.ini contains four sections:
814 Submounts, Drive Mappings, Active Maps and CSC Policies.
815 The Submounts and CSC policies are now stored in the registry under
816 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
817 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
818 The Drive Mappings and Active Maps are stored in the registry under
819 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
820 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
822 There is no automatic migration of this data as it would be impossible
823 to consistently migrate data to user profiles which may not be active
824 when the machine is updated.
826 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
827 fake root.afs volume. For the same reasons as for the cellservdb file,
828 this information should not be in %WINDIR%. This information is now
829 kept under the registry key
830 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
832 The data from the afs_freelance.ini file will be automatically
833 migrated to the registry on first execution of afsd_service.exe
835 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
836 troublesome for several reasons. One, it is confusing for those who
837 expect the file to be named "CellServDB" instead of "afsdcell.ini".
838 Two, this file is not a Windows Profile formatted file. Three,
839 applications should not be reading or writing to %WINDIR%. It causes
840 problems for Windows Terminal Server.
842 The new location of CellServDB will be the OpenAFS Client install
843 directory which is by default C:\Program Files\OpenAFS\Client and can
844 be determined by querying the registry for
845 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
847 The existing afsdcell.ini will be migrated by the NSIS installer.
848 The Wix installer must still be updated to do the same.
850 * Change NSIS installer to use DNS by default; to remove Integrated Logon
851 High Security mode; and to add Terminal Services compatibility registry
852 entries to allow the OpenAFS tools to find the afsdcell.ini and other
853 configuration files in %WINDIR%.
855 * Add support for authenticated SMB connections. This will remove
856 the need for high security mode in most situations. Both NTLM
857 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
858 only NTLM can be used even though Kerberos is now supported. The
859 reason is that it is not possible to construct a service principal
860 which is unique to each individual machine.
862 SMB Extended Auth does not work on XP SP2 unless one of two registry
863 modifications are made:
865 (1) To disable the check for matching host names on loopback connections
866 set this key. This does not require a reboot:
868 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
869 "DisableLoopbackCheck"=dword:00000001
871 (2) To add the AFS SMB/CIFS service name to an approved list. This
872 does require a reboot:
874 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
875 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
877 afsd_service.exe will automatically add the current Netbios Name
878 to the BackConnectionHostNames list and then temporarily disable
879 the loopback check for one cycle of startup/shutdown of the service.
880 We assume most folks do not start/stop without a reboot so this
881 will be adequate in most cases.
883 * Fix security hole in afslogon.dll which allowed passwords to be
884 sent in clear text to the KDC in a misformed principal name.
886 * Fix cm_GetCell() to properly handle expired dns entries
889 * If Freelance mode is active and the afs_freelance.ini
890 file does not exist, do not create an empty file.
891 Instead create a file containing ro and rw mountpoints
892 to the default cell using the standard conventions.
894 * Modify the Freelance support to handle the ability
895 to create rw mount points in the fake root.afs volume.
897 * Changed the RPC mechanism used for token setting from
898 named pipes to local. Use of named pipes can be restored
899 by setting the environment variable AFS_RPC_PROTSEQ to
902 Named pipes were required when a Windows 9x system was
903 using a NT system in gateway mode which is incompatible
904 with our use of local loopback adapters.
906 * In afscreds.exe, if a username of the form user@REALM is
907 specified and no password is specified, do not perform a
908 kinit operation. Only perform the aklog functionality.
910 * Add a new registry value which allows the number of processors
911 on which afsd_service.exe executes to be restricted. Valid
912 values are 1..numOfProcessors
914 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
918 * A second MSI based installer option is now available.
920 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
921 request tickets for user/instance@REALM instead of just user@REALM
923 * Modify the Power Management Notify routine to wait for the Hard Dead
924 timeout period instead of a fixed 19 seconds. With the longer timeout
925 periods Hibernation and Standby could never succeed when network
926 connectivity is not available.
928 * The following fs.exe commands are now restricted to Administrator:
929 - checkservers with a non-zero timer value
932 - sysname with a new sysname list
941 setting the default sysname for a machine should be done via the
942 registry and not via "fs sysname".
944 * NSIS installer adds options to install Debugging Symbols
945 and the Microsoft Loopback Adapter; the user is now also
946 given the ability to select the afscreds.exe startup options.
948 * Build system modified to generate symbols for FREE (aka RELEASE)
949 builds as well as CHECKED (aka DEBUG) builds
951 * Sites which have a volume ID of 0x20000001 assigned to their
952 root.cell volumes have been experiencing problems with accessing
953 the root.cell volume of their cell when Freelance mode has been
954 active. This was because 0x20000001 was assigned to the fake
955 root.afs volume created by freelance. The fake volume id is
956 now set to 0x00000001 to prevent conflicts.
958 * The timeout logic in the AFS Client Service has been wrong
959 for sometime. It is based on two different assumptions.
960 First, the SMB client timeout is a fix value as was the case
961 with OS/2 Lan Manager. This assumption is incorrect. The
962 SMB timeout in Windows is a dynamic value computed based upon
963 a fixed minimum timeout to which is added time based upon the
964 size of the request and the performance characteristics of
965 the connection. Second, it is the responsibility of the
966 SMB Server to enforce the timeout requirements of the client.
967 This is untrue. The SMB Server cannot be expected to know
968 the requirements of the client. More importantly, if the
969 SMB server uses the SMB client timeout as a value to restrict
970 its behavior as an RX client, the performance characteristics
971 of the local SMB session would be used to prematurely terminate
972 WAN connections with significantly different performance
975 The timeout logic has therefore been modified in the following
977 . the Lan Manager Workstation (SMB) Session Timeout is used only
978 as a basis for configuring the Connection Dead Timeout
979 and Hard Dead Timeout values. The Connection Dead Timeout
980 must be at least 15 seconds longer than the SMB Timeout
981 and the Hard Dead Timeout must be at least double the
982 Connection Dead Timeout.
983 . New registry entries have been added to allow the Connection
984 Dead Timeout and Hard Dead Timeout values independent of the
985 Lan Manager Workstation Session Timeout
986 . The test to enforce the SMB Client Timeout has been removed.
988 One of the side-effects of removing the enforcement of the SMB
989 Client Timeout is that regardless of whether or not the SMB client
990 is available to receive the response (and how would the SMB server
991 know) the RX protocol response can be used to update the AFS
992 Client Service state for ready access by future SMB client
995 This should be the end of the "Server paused or restarting messages"
997 * Add support for arbitrary UNC paths to the pioctl() support.
998 This enables the fs commands as well as the AFS Shell Extension
999 to work correctly when UNC paths are being used.
1001 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
1002 DNS if the cell configuration cannot be determined via CellServDB
1004 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
1005 are ever set more than once at a time
1007 * Fix the management of lists of cm_cell_t structures when using
1008 DNS to lookup cell information. The previous code would fail to
1009 reuse the same cellID for a cell if DNS was used more than once
1010 for a given cell name. When the ttl expired, a single cm_cell_t
1011 could be inserted into the cm_allCellsp list more than once
1012 producing a loop. In addition, the vlServerp list belonging to
1013 the cell was not freed resulting in improper refCounting of the
1016 * Add DNS support to cm_IoctlNewCell() which previous only examined
1019 * Add cm_FreeServer() function and call it from cm_FreeServerList()
1020 to properly garbage collect cm_server_t objects
1022 * Add numVCs variable to smb.c to track the number of smb_vc_t
1023 objects created and use it to initialize the vcID field which
1024 previously was set to 0 in all objects resulting in FindByID
1027 * Fixed DNS lookups to work consistently throughout the OpenAFS
1028 product instead of just from within the afsd_service.exe
1030 * Added a runtime check to ensure that AFS Client Service SMB
1031 Server is accepting connections before attempting to mount
1034 * Read IP addresses for volume servers out of the CellServDB
1035 file if gethostbyname() on the hostname fails.
1037 * Fix getcellconfig() to populate both the Hostnames as well
1038 as IP addresses when loading cell data via DNS
1040 * Increase the Connection Dead Time to 50 from 20 seconds
1041 Increase the Hard Dead Time to 120 from 40 seconds
1042 (matches the Unix values)
1044 * Fixed an assertion validating the number of allocated NCBs
1046 * Fixed the build environment to consistently build for
1047 Windows 2000 and above. (APPVER = 5.0)
1049 * Fixed rx_debug to properly validate the receipt in incoming
1050 data with select() and recvfrom(). Do not copy data out of
1051 the socket buffer unless success is indicated.
1054 * afsd_service.exe will now display a message box to the
1055 desktop when it terminates due to an IP Address Change.
1057 * installer no longer deletes AFS Server configuration data
1060 * installer generates a warning dialog if the RPC service
1061 is not properly configured
1063 * installer compressed with lzma instead of bzip2
1065 * afsd_service.exe shutdown crash solved once and for all
1067 * reference counting of smb_vc_t data structures improved
1069 * name space collision of smb_fid_t event objects corrected
1071 * the output of "fs memdump" is now written to
1072 %WINDIR%\TEMP\afsd_alloc.log
1074 * the file TaAfsApp_1033.dll is now properly installed allowing
1075 the User Manager to start
1077 * a new algorithm is used for computing filename pattern matches
1079 * afscreds.exe now accepts user names containing instance
1082 * Fix the Directory Name Lookup Cache to be case-sensitive.
1083 This is crucial in environments in which a Windows client
1084 is accessing a directory with more than one filename that
1085 differs only by case. If the directory contains "FOO"
1086 and "Foo". You want "DEL Foo" to delete the correct one.
1087 We still have a problem in that "DEL foo" will delete a
1088 random filename. This will be addressed in a future release.
1090 * Fix afscreds.exe -M option (renewMaps) to work when High
1091 Security mode is off. Also, remember to disable the ActiveMap
1092 flag in afsdsbmt.ini when a drive mapping is removed.
1094 * Updates to NSIS installer script. AFS Server configuration
1095 data will not be destroyed on un-install or re-install.
1096 Use a better compression algorithm.
1098 * afslogon.dll now uses KFW to obtain tokens when available
1100 * afslogon.dll when given an all uppercase username will
1101 attempt to authenticate with both the uppercase name
1102 and an all lowercase variation
1104 * DST modification removed. The fix appears to make things
1105 worse after a reboot of the machine.
1107 * fs.exe: added "cscpolicy" which is used to
1108 change client side caching policy for AFS shares
1110 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1111 [-documents] [-disable] [-help]
1113 * Several uninitialized variables have been initialized
1115 * It is now possible to obtain tokens using cross realm
1116 Kerberos within afscreds.exe:
1118 user: jaltman@ATHENA.MIT.EDU
1120 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1121 will will in turn be used to obtain afs@DEMENTIA.ORG.
1122 The resulting token will be stored with the display name
1123 jaltman@ATHENA.MIT.EDU@dementia.org
1125 * aklog.exe has been added to the client
1127 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1128 [[-p | -path] pathname]
1132 -d gives debugging information.
1133 krb_realm is the kerberos realm of a cell.
1134 pathname is the name of a directory to which you wish to authenticate.
1135 -noprdb means don't try to determine AFS ID.
1136 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1137 (default is Kerberos V)
1138 No commandline arguments means authenticate to the local cell.
1141 * All of the resource files have been restructured to adhere to
1142 a set of rules IBM implemented for loading string resources.
1143 These rules had either been forgotten or were not discovered
1144 by folks working on the OpenAFS sources. The end result was
1145 memory corruption. This is primary item which was preventing
1146 the AFS Server from working.
1148 * Increased the size of the maximum ticket size stored in a token
1149 from 344 bytes to 12,000. Increased the buffers used to convey
1150 messages between the pioctl() caller and the SMB Server from
1151 1000 bytes to 12,512. The code appeared to have been writing
1152 above the top of the stack by quite a few number of bytes.
1153 (The increased ticket size is necessary for the next item.)
1155 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1156 Instead the raw Kerberos 5 ticket is used in its entirety. This
1157 is extremely important as it allows us to use pure Kerberos 5 KDCs
1158 as the source of the AFS authentication. The use of up to 12,000 byte
1159 tickets will allow tickets produced by all versions of Microsoft
1160 Active Directory to be used.
1161 - create a user account.
1162 - designate it DES only
1164 - specify its UPN to be "afs@realm"
1165 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1167 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1168 is special when using long file names. (you must use "*.*" and not "*")
1169 Instead only enforce it when performing 8dot3 searches.
1171 * Fixed the DST problem with creation times being set one hour ahead
1173 * Fixed the problem when using \\afs\cell-alias. For example,
1174 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1175 for the alias name; instead simply expand the name. One of the
1176 symptoms of this problem was a loss of acquired tokens.
1178 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1179 of strings. (Only English strings provided.)
1181 * Fixed the installer to properly replace in use files.
1183 * Fixed the build system to cleanup generated component version files
1185 * The release build compiled with MSVC 6.0 compiler to avoid the
1186 afsd_service.exe shutdown crash. This does not solve the problem
1187 but simply avoids it for the time being.
1191 * fix afslogon.dll to not corrupt memory when High Security mode
1194 * fix afsd_service.exe to not attempt to restore the stack when
1195 an exception occurs. (not safe in multi-threaded programs)
1197 * fix uninstaller to properly remove the CRT and MFC DLLs
1199 * remove a Message Box from afscreds.exe when getcellconfig()
1200 fails on a kerberos realm which is not a cell
1202 The following is a list of changes to the OpenAFS for Window client
1205 * "fs setserverprefs" will leave afsd service deadlocked
1207 * "vos listaddrs" will core dump
1209 * installer sets the appropriate keys to support Integrated Logon
1211 * installer disables the "Find Lana by Name" functionality as it
1212 was causing headaches for many users
1214 * fix the intermittent crash of the power management thread when
1215 shutting down the AFS Client Service
1217 * optimizes the obtain drive mount list functionality which is
1218 executed every time the mount tab in afscreds.exe and afs_config.exe
1219 are refreshed. (this happens a lot)
1221 * fix the service shutdown logic. add the STOP_PENDING state
1222 and do not accept additional service events after we declare
1225 The following is a list of changes to the OpenAFS for Window client
1228 * flexelint was run against the source tree and hundreds (perhaps
1229 thousands) of corrections were applied to ensure prototypes
1230 were in use; types were used consistently; variables were
1231 initialized; unused variables were removed; etc.
1233 * A wide variety of instrumentation was added including the
1234 ability to produce a stack trace from within afsd_service.exe
1237 * Dynamic configuration of the RDRtimeout value based upon the
1238 LanMan Workstation Session Timeout
1240 * The mount root no longer needs to be called "/afs". This
1241 is now set by a registry value "MountRoot" within the key
1242 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1244 * The cell list is now only read out of afsdcell.ini when the
1245 file changes instead of each time a cell is resolved.
1247 * Thread synchronization was added to cm_server.c and ktc_nt.c
1249 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1250 calloc()/free(). The Global functions were needed on Windows 3.x
1251 but have caused a variety of problems on the Win32 platforms.
1252 Avoiding them is highly recommended by several Microsoft
1253 Knowledgebase articles
1255 * Support for Symbolic Links added to the AFS Shell Extension
1257 * Added a registry value "OverlayEnabled" to determine if
1258 Shell Extension Overlays should be enabled.
1259 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1261 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1262 separate trees for checked and free builds. Build system supports
1263 a custom directory src\WINNT\extra which can be used as a grafting
1264 location of organization specific additions to the build tree.
1266 * New installer built using NSIS 2.0.
1268 * Named all kernel objects in order to allow them to be monitored
1269 with tools such as SysInternals' ProcExp.exe.
1271 * Introduced new EventLog framework for AFSD
1273 * Introduced Power Management interface to AFSD for Standby and
1274 Hibernate modes to allow cache to be flushed prior to network
1277 * Utilize Win32 DNSQuery API instead of internal routines. This
1278 allows DNS SRV queries to be sent to all current domain name
1279 servers. Not just one specified in an INI file. DNS is now
1282 * "NetbiosName" registry value may be used to specify a fixed
1283 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1284 when the loopback adapter is in use. If you need to use the
1285 old notation with a loopback adapter installed specify a registry
1288 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1290 * Refactor all modules which depend on LAN Adapter and NetbiosName
1291 determination in a new library: lanahelper.lib. This allows for
1292 consistent behavior throughout the product.
1294 * Move the afsd.log and afsd_init.log files to the directory specified
1295 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1296 for services. Added the Date to the log entries.
1298 * New registry value "RxMaxMTU" used to limit the size of the RX
1299 packets sent by the AFS Client Service to the Server. In order
1300 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1301 size must be restricted to 1264 or smaller. The latest NSIS
1302 installer sets a value of 1260 by default.
1304 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1305 packets. This is not needed in order to work across the Cisco
1306 VPN but might be needed for other network environments. This
1307 value is not set by the NSIS installer.
1309 * New registry value "HideDotFiles" is used to apply the Hidden
1310 attribute to files whose names begin with a '.'. This value
1311 is set by the NSIS installer.
1313 * New registry value "MaxMpxRequests" allows the maximum number
1314 of multiplexed sessions to be configured at run time. This
1315 value is not set by the NSIS installer. The default value is
1318 * New registry value "MaxVCPerServer" allows the maxmimum number
1319 of VCs per server to be configured at run time. This value is
1320 not set by the NSIS installer. The default value is 100.
1322 * New registry value "AllSubmount" allows the "all" submount to
1323 be disabled by setting its value to 0x00.
1325 * Allow cells names to be valid mount points
1326 \\<netbiosName>\<cellname>
1328 * Store the active state of drive mappings in order for afscreds.exe
1329 to restore them upon startup
1331 * Add exception handling to generate a Stack Trace to the afsd_init.log
1332 file if one happens to occur.
1334 * Add lots of logging to help detect the cause of invalid SMB packets
1336 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1337 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1338 renewal of expiring tokens as long as afscreds.exe is running.
1340 * New afscreds.exe command line options:
1342 -M = renew drive maps
1343 -N = ip address change detection
1346 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1347 determines whether or not MIT Kerberos for Windows should be used
1348 to obtain tokens via Kerberos 5 tickets.
1350 * New registry value "AfscredsShortcutParams" in
1351 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1352 determines the command line parameters to be specified when "fixing"
1353 the AFS Shortcut in the user's startup folder.
1355 * The "ShowTrayIcon" registry value has been moved from
1356 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1357 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1359 * The <cell name> registry values used to store the token expiration
1360 reminders have been moved from
1361 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1362 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1364 * Obtain the Logon User Name from the Explorer key when available
1366 * new text document doc\txt\winnotes\registry.txt lists all registry
1367 values used by OpenAFS (excluding the AFS Server)
1369 * BUG: rx_securityClass objects were not properly reference
1370 counted and were never freed.
1372 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1373 would be generated. The existence of a server does not imply
1374 that it is not down. If all of the servers for a cell are down
1375 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1378 * BUG: the directory name lookup cache failed to free the entries
1379 in the cache when the name cache entries cycled. The entries
1380 in the cache would become dereferenced without being freed.
1382 * BUG: fs setserverprefs could be executed without Administrator
1385 * BUG: the number of allocated NCB objects (100) exceeded the number
1386 which could actually be waited upon by the kernel (64). Any objects
1387 which were utilized above the limit could never have event completions
1390 * BUG: smb_username_t objects were not being reference counted and
1391 were not properly freed.
1393 * BUG: smb_tid_t objects could under unusual circumstances be freed
1394 before they were no longer referenced.
1396 * BUG: smb_fid_t object pointer were frequently used even when
1397 their value could be NULL. They were not properly released and
1398 therefore they were never freed.
1400 * BUG: smb_packet_t data structures were not completely initialized
1403 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1404 Denied" because that causes the Explorer Shell to try again until
1405 access is obtained. Instead return "Remote Resources" which allows
1406 the shell to move on and treat the error as transient.
1408 * BUG: when initializing the NCBreturns structure, separate Event objects
1409 were created for each NCB although a single Event object was supposed
1410 to be shared by all.
1412 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1415 * BUG: smb_tran2Packet_t objects were not being properly referenced
1418 * BUG: directory path creation did not handle the case of multiple
1419 directories requiring creation in one attempt
1421 * BUG: SMB requests which required an Extended Response were ignored.
1422 This prevented some files from being written to AFS volumes.
1424 * BUG: character strings were being freed even after they were
1425 inserted into in use data structures
1427 * BUG: inconsistent usernames were used when High Security mode was
1428 enabled. (there is still much to do in this area)
1430 * BUG: pioctl() calls which require out of band RPC operations were
1431 susceptible to race conditions when performed by multiple processes
1433 * BUG: memory allocation and deallocation crossed instances of the
1434 C Runtime Library producing memory leakage and corruption in
1435 afscreds and the client configurator.
