2 * Fixed a locking error in cm_TryBulkStat() which had the
3 potential of deadlocking the system for the length of time
4 it takes to perform a bulk status fetch operation.
6 * Replaced time conversion code (UnixTime <-> FILETIME) to
7 be completely arithmetic instead of relying on a bizarre
8 algorithm involving a variety of C RTL time functions.
10 * Fixed a invalid memory access under a bizarre circumstance.
11 Windows will allow a physical mass media device to be
12 installed via Plug N Play to the system and will assign it
13 the lowest available drive letter. This is true even if the
14 drive letter is currently assigned in the user session to
15 a network device via NET USE (or its equivalent.) When this
16 happens, queries sent to the CIFS server will contain invalid
17 data. This invalid data was not being caught by the AFS
18 Client Service and was resulting in a crash when Freelance
21 * Fixed a reference count error when registering callbacks
22 on a stat cache object if the callback was already registered
24 * Add a case to cm_Analyze() in order to handle the case where
25 cm_GetConnByMServers() returns CM_ERROR_NOSUCHVOLUME because
26 the server list for the volume is empty. In this case, force
27 an update of the volume info and retry.
29 * Insert a missing cm_EndCallbackGrantingCall() which could
30 result in threads waiting for a callback to complete to never
33 * In the persistent cache, there is a maximum number of volume
34 entries. Allow volume entries to be reused if the maximum
35 number have been allocated and their reference count is zero.
37 * If we already have a dead virtual connection object, don't
38 ignore the fact that additional dead vc objects must be taken
41 * Removed a deadlock condition introduced in the summer of 2004.
42 Do not hold mx locks around calls to RX functions including
43 rx_NewCall(). That is what reference counts on the rx_connection
46 * Fixed an initialization error in afslogon.dll which could
47 result in random behavior including a failure to terminate
48 the NPLogon function. (1.3.80b)
50 * Fixed an error preventing the use of SMB authentication
51 on Windows 2000. (1.3.80a)
54 * Updated CellServDB to Public CellServDB 16 Mar 2005
56 * Fixed DNS AFSDB queries to ensure that "csail" cannot be
57 misinterpretted as "csail.mit.edu" when the resolver
58 is configured to append ".mit.edu" to failed DNS queries.
60 * Fixed another case in which the client would replace connections
61 to the host when it was not necessary. In this case the
62 situation would occur if cryptall was on and the connections
63 were unauthenticated due to lack of an appropriate token.
65 * OpenAFS for Windows has failed to work at sites which are
66 utilizing a cross-realm trust between an MIT/Heimdal realm
67 and a multi-domain Windows forest when the workstation being
68 accessed is not located in the root domain. This is caused
69 by a bug in the workstation which was triggered after the
70 introduction of Windows 2003 Server. When the bug is triggered,
71 the workstation attempts to authenticate users to afsd_service.exe
72 by contacting the Domain Controller instead of using the
73 LSA loopback authentication mechanism.
75 One of the reasons this bug occurs is because the workstation
76 does not have a reliable way of knowing that the service whose
77 netbios name is "AFS" is located on the workstation. This will
78 be fixed starting in Longhorn Beta 1 by Microsoft. The
79 "BackConnectionHostNames" registry value will be used to
80 indicate that the authentications to that service name should
81 be performed using the loopback authentication mechanism.
83 In the meantime, when Logon Caching is enabled, we can force
84 afsd_service.exe to authenticate using the logon cache before
85 contacting the Domain Controller. This will work with both
86 password and smart card based logons.
88 * The allDown logic in cm_ConnByMServers() was wrong. The allDown
89 flag should not be cleared if a volume's server reference is
90 marked as "offline". In the case where all of the volume's
91 servers are either "down" or the volumes are "offline", we want
92 cm_Analyze() to process the condition as CM_ERROR_ALLOFFLINE
93 instead of as CM_ERROR_TIMEDOUT. In fact, CM_ERROR_TIMEDOUT
94 should never occur in practice.
96 In the case of CM_ERROR_ALLOFFLINE, cm_Analyze() will sleep for
97 5 seconds, clear the server down and volume busy flags, and
98 then force an update from the VLDB. This allows the client to
99 update the location of a volume if the reason for it being
100 marked offline is because it is being moved. Calls to
101 cm_ConnByMServers() will be retried either until success or
102 the RDRtimeout period is reached.
104 * Correct the Power Management code behavior in response to
105 Standby, Suspend, and Shutdown events. Instead of flushing the
106 buffers associated with the mounted SMB submounts, simply write
107 all buffers which are marked dirty.
109 * Added support for "TheseCells" to afslogon.dll. "TheseCells"
110 provides a list of cells other than the default cell for which
111 tokens should be obtained using the default Kerberos principal.
112 This functionality is logon domain specific and is only available
113 when using KFW for authentication.
115 * Fixed FindNext Invalid Handle error caused by over agressive
116 attempts at garbage collecting dirSearch entries when the
117 dirSearch ID wraps from the maximum value to 1.
119 * Add support for registry defined server preferences for VLDB and
120 File servers. See registry.txt for details.
122 * Increased default cache size to 96MB and default number of cache
125 * Fixed refCount leaks related to directory lookups and pioctl calls.
127 * Callbacks revoked during a race condition with an attempt to
128 obtain the same callback no longer result in an inaccessible
131 * New command line tool:
133 afsdacl : Set or reset the DACL to allow starting or stopping
134 the afsd service by any ordinary user.
136 Usage : afsdacl [-set | -reset] [-show]
138 -reset : Reset the DACL
139 -show : Show current DACL (SDSF)
141 * IP addresses are no longer queried once at startup. Instead IP
142 addresses are obtained as needed. Loopback adapter addresses are
143 no longer published to the server.
145 * Pay attention to the MIT KFW registry configuration for automatic
146 importation of MSLSA credentials. (SOFTWARE\MIT\Leash32,MsLsaImport)
148 * Fix (once again) case-sensitive comparisons which was apparently
151 * Activate support for vos listvol -format
153 * Population of the "AFS Client Admins" group failed on non-English
154 versions of Windows because the name of the "Administrators" group
155 is localized. Now we lookup the name of the group by using the
156 Administrators Group Alias Relative ID.
158 * Multiple cell token acquisition within afscreds.exe was broken in the
159 case of Kerberos 5 cross realm authentication. Instead of contacting
160 the KDC associated with the cell's realm, afscreds would obtain a
161 token from the KDC of the user's realm. This would result in
162 "invalid kvno errors" while authenticating to the AFS servers.
163 Unauthenticated access would work. The symptoms would vary based upon
164 whether or not the VLDB servers had been contacted using unauthenticated
165 connections prior to the user obtaining tokens.
167 * The list of ACL entries was becoming corrupted. It appears as if
168 an ACL when it expires was not being appropriately cleaned up. In
169 fact, it was left in the list of ACLs associated with the scache
172 * Changed the default @sys name list to "x86_win32 i386_w2k i386_nt40"
173 for 32-bit x86 systems. The default for itanium will be "ia64_win64"
174 and "amd64_win64" for amd 64-bit processors.
176 * When executing executables, Windows provides a mechanisms by which
177 the normal search for DLLs can be bypassed. If a file foo.exe is
178 being executed and there exists a file or directory "foo.exe.local"
179 (the contents are ignored if a file), then Windows will search for
180 DLLs first in the "foo.exe.local" directory and second in the
181 directory in which the "foo.exe" file is located.
183 Previous releases of OAFW would improperly return
184 STATUS_NOT_A_DIRECTORY instead of the expected
185 STATUS_OBJECT_PATH_NOT_FOUND. This would cause the Windows SMB client
186 to terminate the search for the DLL causing the execution of the
189 * Rework the reference counting of smb_vc_t objects. The references
190 stored in the waiting locks were not counted. This could result in
191 an assertion if the reference count drops to zero.
193 * "fs wscell" returns "Freelance.Local.Root" for the workstation cell
194 when running in freelance mode.
196 * Added support for persistent caching of file contents, stat entries,
197 volume data, cell data, and name lookup data. When the registry
198 value, "NonPersistentCaching", is not defined or set to 0 the file
199 specified by "CachePath" becomes a persistent cache file. The
200 size of the cache file is computed at run time. It has a maximum
201 size of approximately 1.2GB. The contents of the file will be
202 validated according to the rules specified by the "ValidateCache"
205 * Added support for UUIDs. UUIDs are kept for as long as the
206 cache file is intact.
208 * Added cmdebug.exe and support cache manager debugging callback
209 interfaces in afsd_service.exe.
211 Usage: cmdebug -servers <server machine> [-port <IP port>] [-long]
212 [-addrs] [-cache] [-help]
213 Where: -long print all info
214 -addrs print only host interfaces
215 -cache print only cache configuration
217 * Symlinks to \\AFS\[all\]... will now be treated the same as
218 symlinks to /afs/.... However, please use /afs/... as otherwise
219 the symlinks won't work on Unix.
221 * Correct a problem with local CellID allocation for cells whose
222 server list is obtained via DNS instead of a CellServDB file. If
223 the DNS information expires the CellID assigned to the entry will
224 be changed. This causes all of the cm_scache_t objects which refer
225 to the old cellID number to become useless. Attempts to access
226 files or directories with cm_scache_t objects using the old cellID
227 will fail since the server list cannot be obtained.
229 * Correct deadlock condition in cm_EndCallbackGrantingCall which can
230 be triggered if the volume referenced by the cm_scache_t object is
233 * The AFS Service needs to respond to SERVICE_ACCEPT_SHUTDOWN messages
234 in addition to SERVICE_ACCEPT_STOP.
236 * Move RPC shutdown until after the SMB and RX shutdown procedures
237 complete. Block until RPC shutdown is complete.
239 * Modify afslogon.dll (integrated logon) to wait for service if its
240 state is START_PENDING. If the timeout period occurs, reset to
241 the retry interval and not the sleep interval.
243 * When renewing the server list for a cell obtained via DNS AFSDB
244 records, the cm_cell_t entry must be removed from the list of all
245 cells. Otherwise, the list of cells will be corrupted.
247 * In the dcache and scache modules, use the cm_scache_t dataVersion
248 instead of the cm_fakeDirVersion.
250 * Synchronize fs.c with the unix version.
252 * The variable used to determine whether a file or virtual memory
253 mapped cache is used was not properly initialized to a default
254 value. If the registry setting "NonPersistentCaching" was not
255 set, the choice would be random. Properly initialized to be
258 * The memory mapped view was never unmapped before closing the file
259 at service shutdown. This is now properly cleaned up.
261 * Default location of Cache file is now %TEMP%\AFSCache
265 * A bug affecting new installations of 1.3.75/76 would result in
266 the creating of incorrect mountpoints in the freelance root.afs
267 volume for the default cell.
269 If "fs \\afs\all\<cellname>" lists a volume name of "root" instead
270 of "root.cell", you have been affected by the bug. To correct the
271 problem, execute the following commands:
273 fs rmmount \\afs\all\<cellname>
274 fs rmmount \\afs\all\.<cellname>
276 fs mkmount \\afs\all\<cellname> root.cell <cellname>
277 fs mkmount \\afs\all\.<cellname> root.cell <cellname> -rw
281 * A bug has been fixed in the auto-generation of Freelance root.afs
282 symlinks which produced random entries in the \\AFS\all directory.
284 * Support has been added for multi-homed servers
287 * Added a new registry value, "StoreAnsiFilenames", which can be used
288 to force the use of ANSI character sets instead of OEM Code Pages.
289 This feature is useful when users require the ability to create
290 filenames with 8-bit characters and need to access the files from
291 both Latin-1 based Unix systems as well as from Windows.
293 Activation of this feature will prevent access to files stored with
294 8-bit OEM characters.
296 * Shutdown all SMB threads in a synchronized manner when stopping the
299 * There is currently a maximum cache size of 1.3GB. The limit is imposed
300 by the largest contiguous block of unused memory within the 2GB process
301 space which can be assigned to the memory mapped file. Unfortunately,
302 when the executable digital signature verification code is activated
303 Windows sees fit to further segment the process memory which in turn
304 reduces the size of the maximum cache file to less then 800MB. If
305 larger cache sizes are desired, a new registry value should be set:
307 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
309 Setting this value will disable the runtime verification of digital
310 signatures on afsd_service.exe and the afs dlls which it loads. It
311 will not disable the the version number check on those same files.
312 The signature verification is not a security messure and is only meant
313 to enhance the ability to afsd_service.exe to detect potential
314 destablizing mixtures of DLLs from incompatible distributions.
316 Added code to auto-disable the signature verification check if
317 the desired cache size is greater then 700MB.
319 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
320 used to verify the validity of the afsd_service.exe binary
321 as well as each of the AFS DLLs loaded by the service. Not only
322 must the digital signature be valid but the signatures of the
323 DLL must be signed by the same entity as the service.
325 * Implement new functions: cm_freelanceMountPointExists and
326 cm_freelanceSymlinkExists. Use them along with other validity
327 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
328 ensure that name collisions do not occur and that empty strings
329 are not valid file names.
331 A symlink may not have a name which would resolve to a valid
332 cell name. Doing so would prevent access to the cell.
334 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
335 re-initialization code. The reference counts of the fake root.afs
336 volume scache object(s) would become invalid when the mount point
337 or symlink lists were altered.
339 * Add registry entries to provide mappings from the afsdsbmt.ini
340 to the new locations for applications which count on the use
341 of the old Profile file APIs. These apps are likely to fail
342 if the user does not have administrator privileges and the
343 registry is locked down.
345 * The afs_config.exe submounts dialog had two errors.
346 First, attempts to remove entries failed because the registry
347 key was being opened without KEY_WRITE privileges.
348 Second, when editing a submount entry, changing the name
349 would add a new key and leave the original one in place.
350 Now the original submount will be removed if its name is
353 * In recent months there have been several incidents in which
354 users have experienced problems starting or accessing
355 afsd_service.exe and after significant effort has been spent
356 it has turned out that they have two versions of AFS on the
357 machine or an inconsistent set of DLLs.
359 Code has now been added to afsd_service.exe which will walk
360 the list of modules loaded by afsd_service.exe and validate
361 that the version of the AFS DLLs matches the version of the
362 afsd_service.exe executable. If they do not match the service
365 * When Freelance mode is enabled and there is no registry
366 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
367 will attempt to import the afs_freelance.ini file contents.
368 If the file does not exist, it was creating a dummy file
369 with a r/o and r/w entry for the default cell and then
370 importing those values.
372 This process has been changed. The temporary file is no
373 longer created. Also, both the OpenAFS Client install
374 directory as well as %WINDIR% are checked for previous
375 afs_freelance.ini files.
377 * Added support for VL_GetEntryByNameN(). Still need to add
378 support for VL_GetEntryByNameU() for multi-homed support.
380 * Fix a deadlock situation in afscreds.exe when canceling an
381 auto-generated Obtain Tokens dialog
384 * Fix the locking of objects during Directory Searches in the
385 SMB/CIFS server. The failure to properly lock the reference
386 counts was resulting in the premature freeing of smb_dirSearch_t
387 objects while they were still in use by the SMB/CIFS client.
388 This does not solve the "Invalid Handle" problem.
390 * Fix Find Cell By Name pioctl call to return a valid cell
391 name for the Freelance fake root.afs volume.
392 "Freelance.Local.Root".
394 * Fix the Explorer Shell Extension Symlinks->Add operation.
395 The dialog template was missing and the link destination
396 string was too short.
398 * Add support for symlinks to Freelance root.afs volume
399 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
400 <number> = "<linkname>:<relative-path>."
401 Use symlink.exe to create, list, or remove
403 * Remove the fallback to the use of KFW's KRB4 library when obtaining
404 tokens. We never obtain KRB4 tickets.
406 * Fix AFS Client Configuration Control Panel to support new SysName
409 * Fix a bug in afsd_service.exe which could result in the SysName
410 not being read from the registry.
413 * Add code to block the issuance of AFS tokens by aklog.exe or
414 afscreds.exe when the Kerberos 5 principal name contains a dot.
416 * Modify the IsAdmin() function to always treat the local SYSTEM
417 account as an AFS client administrator. Affects fs.exe and
420 * Modify the internal handling of Quota Exceeded errors
422 * Upgrade all reference count fields in the Windows cache manager
423 and the osi library to use unsigned long instead of signed short.
424 A similar fix has been applied to the afs rpc (rx) library.
426 * fix the Windows cache manager to prevent it from replacing the
427 rx_connection object associated with the cm_conn_t object on each
428 and every operation if "fs crypt" was set. This explains the
429 dramatic performance difference when crypt is used vs clear.
430 The problem: 'cryptall', a boolean flag indicating whether or not
431 "fs crypt" is set, was being compared to the rx_connection
432 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
433 1 != 2 and therefore the rx_connection was always destroyed
434 and replaced on each and every operation.
436 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
437 It is not safe for the cm_conn_t object to not be locked because
438 rx_DestroyConnection might be called from another thread if:
439 - the user's tokens have changed or expired
440 - the crypt mode has changed
442 This fix appears to have also taken care of the problems associated
443 with Overlapped Writes resulting in Delayed Write errors.
445 * fix NSIS installer's AdminGroup.exe to properly create and
446 remove groups when given -create or -remove. The string comparison
449 * fs sysname now accepts a list of sysname values
451 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
452 DWORD which when set to a non-zero value will cause error message
453 text to be output to stderr from the pioctl() routine. Useful in
454 debugging failures of fs.exe, tokens.exe, etc.
456 * added a test to the power management code to only perform a
457 flush operation if there is at least one network adapter which
458 is not a loopback adapter.
460 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
461 "EnableKFW". This value will not be read if the key
462 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
463 value under that key does not.
465 * provide mechanisms to force the use of krb524d for Kerberos 5
466 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
467 there is a new registry value "Use524" and for aklog.exe a new
468 command line parameter "-m".
470 * Fix the pattern matching algorithm to properly match patterns
473 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
474 which is used by both the original function and the new
475 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
476 creation of HardLinks in addition to Renaming. smb_Link()
477 is a new function which creates HardLinks via cm_Link().
478 cm_Link() is a new vnodeops function which creates links
481 smb_ReceiveNTRename() does not support the File Copy and
482 Move Cluster Information operations described in its interface.
483 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
485 * When opening files via symlinks, we should follow the symlinks
486 until we reach the actual file stat cache entry. The stat cache
487 entry of the file should then be stored in the FID instead of
488 stat scache entry of the symlink.
490 * return bad operation errors for all unimplemented functions
491 even if we do not know the functions exist.
493 * Log bad packets and unknown operation packets to the trace log
495 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
498 * Update list of known CIFS operations to include all those listed
499 in CIFS-TR-1p00_FINAL.pdf.
501 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
502 to support the REG_EXPAND_SZ type.
505 * A new Windows authorization group "AFS Client Admins" is now
506 created and populated with the members of the "Administrators"
507 group. The group is used to determine which accounts on the
508 machine may be used to modify the AFS Client Configuration via
509 the UI and command line tools. afs_config.exe, fs.exe,
511 * Modify the WinLogon Logoff Event Handler to query NT4 domain
512 controllers for the remote profile path if Active Directory
513 services are not available.
515 * Fix aklog.exe to not add the AFS ID to the username
517 * PTS registration of new users to foreign cells has been added to
520 * The cm_Daemon thread is used to perform checks for
521 down servers, up servers, volumes, callback expirations,
522 lock maintenance and token expiration. Due to a gaff in
523 larger integer division the thread never performed any
524 work. Instead the current time computation would always
525 be less then the trigger times. This had an adverse affect
526 on the client's ability to maintain communication with servers,
527 keep volumes up to date, and flush user tokens and acls
528 when they have expired. This was broken when the 1.3 branch
529 was modified to support VC7 which no longer included
532 * An initialization problem with the Freelance code was
533 detected while fixing the callbackRequest. The cm_rootSCachep
534 object is obtained during afsd_InitDaemons() but the callback
535 information is incomplete. The callback information will not
536 be obtained until cm_MergeStatus is called from within
537 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
538 test for the conditions under which the callback information
541 * Reports have been filed indicating that callbacks were
542 being lost. An examination of the code indicated that the
543 cm_server_t objects were not being properly reference
544 counted by the cm_scache_t and cm_callbackRequest_t objects.
545 In particular, the cm_server_t objects may have been freed
546 from beneath the cm_conn_t objects.
548 All of the reference counting is now done via the functions:
553 this improves the ability to track the referrals.
555 Each cm_BeginCallbackGranting Call now allocates a reference
556 to the cm_server_t. The cm_EndCallbackGrantingCall either
557 frees the reference or transfers it to the cm_scache_t
558 cbServerp field. These are then appropriately tracked
559 through the cm_Analyze call.
561 * Ensure that the dnlc hash table is the same size as the
562 dir name hash table (as per original author's note).
563 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
564 for compatibility with 64-bit systems.
566 * fix smb_ApplyV3DirListPatches to properly apply the hidden
567 attribute to dotfiles when the infoLevel < 0x101 and
568 cm_SyncOp has failed.
570 * Fix the Freelance registry initialization code. There
571 was a possibility that some systems could end up with
572 garbage in the registry during a clean install.
575 * file and directory names beginning with "." will now be given the
576 hidden attribute when the volume access is anonymous. this matches
577 the behavior when the volume access is via an authenticated user.
579 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
580 key. When a change occurs mark the root.afs data as invalid and
581 for it to be reloaded on the next access. This allows administrators
582 to modify the mount point list without restarting the service.
584 The freelance client used to provide a fake modification time for
585 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
586 Added code to extract the last modification time of the Freelance
587 registry key and use that instead. The time now represents the
588 most recent mount point change.
590 * PTS registration of new users to foreign cells has been added to
593 * Additional Cache Control and Credential Manager options have been
594 added to the WiX installer. See deployment guide for details.
596 * The CachePath setting is now optionally a REG_EXPAND_SZ type
598 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
601 * The loopback installation code may have had a problem updating the
602 %ETC%\HOSTS file which could have resulted in a premature failure.
603 Work around code has been added for the case where the file cannot
606 * The default max chunksize was increased from 15 (32K) to 17 (128K)
607 because Windows sends 64K blocks when using overlapped writes.
609 * The default number of server threads was increased from 4 to 25 to
610 better handle overlapped writes.
612 * The "AfscredsShortcutParams" registry value was not being properly
613 loaded by afscreds.exe. Therefore, the default value was always being
614 used instead of the value set by the installer.
616 * Windows XP provides downgrade attack detection to prevent an attacker
617 from being able to force the use of NTLM simply by disrupting
618 communication with the KDC. This attack cannot exist between the
619 Windows CIFS client and the AFS Client Service. Therefore, when a
620 downgrade has been detected the afs pioctl library will force the
621 establishment of a new CIFS connection using NTLM.
623 * A locking error was discovered surrounding all references to volume
624 server lists within the cm_cell.c source file.
626 * The logged into Windows username was incorrect on Terminal Server
629 * A new registry value "NonPersistentCaching" was added to the service
630 parameters key. When set to a non-zero value, the afs cache is stored
631 in the Windows paging file. There are two limitations to choosing
633 1. when persistent caching is implemented it won't work with
634 this flag set since there will be nothing to persist.
635 2. with this flag set the initial paging allocation cannot be
636 changed while the service is running
638 * An initialization bug was discovered in aklog.exe which affected users
639 who have a domain name for their afs servers which could not be mapped
643 * afs_config.exe now validates cell names against DNS in addition
644 to the CellServDB file.
646 * In order to allow the freelance client to connect to a volume with ID
647 equal to 1 on the default cell we changed the fake root.afs volume ID
648 once again. This time we choose 0xFFFFFFFF. In addition, we change
649 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
650 It will now be impossible for a volume ID to match that of another
651 cell unless the client is connected to 0xFFFFFFFD cells. That should
652 be enough room for growth.
654 * Fix "fs mkmount" command to work with UNC paths and when
655 started from non-AFS drives. It is now possible to create a mount
656 point in the freelance fake root.afs volume with the command
658 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
662 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
663 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
665 * The algorithm used to re-attempt access to the servers associated with
666 a volume has been altered to properly address the case in which all
667 servers have been marked down. The previous algorithm did not reset
668 the server's down flags so the servers were never actually retried.
669 This caused a problem with active volumes if the network connectivity
670 was lost as could be the case with a network cable removal, wireless
671 drop, or laptop hibernation. With the fix volume access is restored
672 almost instantenously when network connectivity becomes available.
674 * Support for SMB/CIFS browsing has been added to the AFS Client Service
675 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
676 listing of AFS submounts and freelance mount points. Support for
677 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
678 significantly enhances the behavior of AFS volumes within the Explorer
679 Shell. For instance, "AFS" now shows up as server in the Explorer
680 with each submount or freelance mount point visible as a share.
681 The right click menu in each folder now works with full functionality
682 on a consistent basis.
684 * The network provider can be configured to have different behavior
685 depending on the domain that the user logs into. These settings are
686 only relevant when using integrated login. A domain refers to an
687 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
688 local machine (i.e. local account logins). The domain name that is
689 used for selecting the domain would be the domain that is passed into
690 the NPLogonNotify function of the network provider. (see registry.txt
693 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
694 "Authentication Cell" which may be used to specify a default
695 authentication cell for afscreds.exe which is different from
696 the default cell for the AFS Client Service daemon.
698 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
699 afslogon.dll moved to %WINDIR%\System32\.
700 New registry entries added to register the dll for Winlogon events.
702 The logoff event will now force a call to ktc_ForgetAllTokens()
703 using the context of the user being logged off as long as the
704 user's profile is not loaded from within AFS. If the profile
705 was loaded from AFS we can't release the tokens since the Logoff
706 event is triggered prior to the profile being written back to
707 the its source location. This is now performed in an XP SP2
710 * Windows XP SP2 Internet Connection Firewall interoperability
713 * The %WINDIR%\afsdsbmt.ini contains four sections:
714 Submounts, Drive Mappings, Active Maps and CSC Policies.
715 The Submounts and CSC policies are now stored in the registry under
716 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
717 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
718 The Drive Mappings and Active Maps are stored in the registry under
719 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
720 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
722 There is no automatic migration of this data as it would be impossible
723 to consistently migrate data to user profiles which may not be active
724 when the machine is updated.
726 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
727 fake root.afs volume. For the same reasons as for the cellservdb file,
728 this information should not be in %WINDIR%. This information is now
729 kept under the registry key
730 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
732 The data from the afs_freelance.ini file will be automatically
733 migrated to the registry on first execution of afsd_service.exe
735 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
736 troublesome for several reasons. One, it is confusing for those who
737 expect the file to be named "CellServDB" instead of "afsdcell.ini".
738 Two, this file is not a Windows Profile formatted file. Three,
739 applications should not be reading or writing to %WINDIR%. It causes
740 problems for Windows Terminal Server.
742 The new location of CellServDB will be the OpenAFS Client install
743 directory which is by default C:\Program Files\OpenAFS\Client and can
744 be determined by querying the registry for
745 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
747 The existing afsdcell.ini will be migrated by the NSIS installer.
748 The Wix installer must still be updated to do the same.
750 * Change NSIS installer to use DNS by default; to remove Integrated Logon
751 High Security mode; and to add Terminal Services compatibility registry
752 entries to allow the OpenAFS tools to find the afsdcell.ini and other
753 configuration files in %WINDIR%.
755 * Add support for authenticated SMB connections. This will remove
756 the need for high security mode in most situations. Both NTLM
757 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
758 only NTLM can be used even though Kerberos is now supported. The
759 reason is that it is not possible to construct a service principal
760 which is unique to each individual machine.
762 SMB Extended Auth does not work on XP SP2 unless one of two registry
763 modifications are made:
765 (1) To disable the check for matching host names on loopback connections
766 set this key. This does not require a reboot:
768 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
769 "DisableLoopbackCheck"=dword:00000001
771 (2) To add the AFS SMB/CIFS service name to an approved list. This
772 does require a reboot:
774 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
775 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
777 afsd_service.exe will automatically add the current Netbios Name
778 to the BackConnectionHostNames list and then temporarily disable
779 the loopback check for one cycle of startup/shutdown of the service.
780 We assume most folks do not start/stop without a reboot so this
781 will be adequate in most cases.
783 * Fix security hole in afslogon.dll which allowed passwords to be
784 sent in clear text to the KDC in a misformed principal name.
786 * Fix cm_GetCell() to properly handle expired dns entries
789 * If Freelance mode is active and the afs_freelance.ini
790 file does not exist, do not create an empty file.
791 Instead create a file containing ro and rw mountpoints
792 to the default cell using the standard conventions.
794 * Modify the Freelance support to handle the ability
795 to create rw mount points in the fake root.afs volume.
797 * Changed the RPC mechanism used for token setting from
798 named pipes to local. Use of named pipes can be restored
799 by setting the environment variable AFS_RPC_PROTSEQ to
802 Named pipes were required when a Windows 9x system was
803 using a NT system in gateway mode which is incompatible
804 with our use of local loopback adapters.
806 * In afscreds.exe, if a username of the form user@REALM is
807 specified and no password is specified, do not perform a
808 kinit operation. Only perform the aklog functionality.
810 * Add a new registry value which allows the number of processors
811 on which afsd_service.exe executes to be restricted. Valid
812 values are 1..numOfProcessors
814 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
818 * A second MSI based installer option is now available.
820 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
821 request tickets for user/instance@REALM instead of just user@REALM
823 * Modify the Power Management Notify routine to wait for the Hard Dead
824 timeout period instead of a fixed 19 seconds. With the longer timeout
825 periods Hibernation and Standby could never succeed when network
826 connectivity is not available.
828 * The following fs.exe commands are now restricted to Administrator:
829 - checkservers with a non-zero timer value
832 - sysname with a new sysname list
841 setting the default sysname for a machine should be done via the
842 registry and not via "fs sysname".
844 * NSIS installer adds options to install Debugging Symbols
845 and the Microsoft Loopback Adapter; the user is now also
846 given the ability to select the afscreds.exe startup options.
848 * Build system modified to generate symbols for FREE (aka RELEASE)
849 builds as well as CHECKED (aka DEBUG) builds
851 * Sites which have a volume ID of 0x20000001 assigned to their
852 root.cell volumes have been experiencing problems with accessing
853 the root.cell volume of their cell when Freelance mode has been
854 active. This was because 0x20000001 was assigned to the fake
855 root.afs volume created by freelance. The fake volume id is
856 now set to 0x00000001 to prevent conflicts.
858 * The timeout logic in the AFS Client Service has been wrong
859 for sometime. It is based on two different assumptions.
860 First, the SMB client timeout is a fix value as was the case
861 with OS/2 Lan Manager. This assumption is incorrect. The
862 SMB timeout in Windows is a dynamic value computed based upon
863 a fixed minimum timeout to which is added time based upon the
864 size of the request and the performance characteristics of
865 the connection. Second, it is the responsibility of the
866 SMB Server to enforce the timeout requirements of the client.
867 This is untrue. The SMB Server cannot be expected to know
868 the requirements of the client. More importantly, if the
869 SMB server uses the SMB client timeout as a value to restrict
870 its behavior as an RX client, the performance characteristics
871 of the local SMB session would be used to prematurely terminate
872 WAN connections with significantly different performance
875 The timeout logic has therefore been modified in the following
877 . the Lan Manager Workstation (SMB) Session Timeout is used only
878 as a basis for configuring the Connection Dead Timeout
879 and Hard Dead Timeout values. The Connection Dead Timeout
880 must be at least 15 seconds longer than the SMB Timeout
881 and the Hard Dead Timeout must be at least double the
882 Connection Dead Timeout.
883 . New registry entries have been added to allow the Connection
884 Dead Timeout and Hard Dead Timeout values independent of the
885 Lan Manager Workstation Session Timeout
886 . The test to enforce the SMB Client Timeout has been removed.
888 One of the side-effects of removing the enforcement of the SMB
889 Client Timeout is that regardless of whether or not the SMB client
890 is available to receive the response (and how would the SMB server
891 know) the RX protocol response can be used to update the AFS
892 Client Service state for ready access by future SMB client
895 This should be the end of the "Server paused or restarting messages"
897 * Add support for arbitrary UNC paths to the pioctl() support.
898 This enables the fs commands as well as the AFS Shell Extension
899 to work correctly when UNC paths are being used.
901 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
902 DNS if the cell configuration cannot be determined via CellServDB
904 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
905 are ever set more than once at a time
907 * Fix the management of lists of cm_cell_t structures when using
908 DNS to lookup cell information. The previous code would fail to
909 reuse the same cellID for a cell if DNS was used more than once
910 for a given cell name. When the ttl expired, a single cm_cell_t
911 could be inserted into the cm_allCellsp list more than once
912 producing a loop. In addition, the vlServerp list belonging to
913 the cell was not freed resulting in improper refCounting of the
916 * Add DNS support to cm_IoctlNewCell() which previous only examined
919 * Add cm_FreeServer() function and call it from cm_FreeServerList()
920 to properly garbage collect cm_server_t objects
922 * Add numVCs variable to smb.c to track the number of smb_vc_t
923 objects created and use it to initialize the vcID field which
924 previously was set to 0 in all objects resulting in FindByID
927 * Fixed DNS lookups to work consistently throughout the OpenAFS
928 product instead of just from within the afsd_service.exe
930 * Added a runtime check to ensure that AFS Client Service SMB
931 Server is accepting connections before attempting to mount
934 * Read IP addresses for volume servers out of the CellServDB
935 file if gethostbyname() on the hostname fails.
937 * Fix getcellconfig() to populate both the Hostnames as well
938 as IP addresses when loading cell data via DNS
940 * Increase the Connection Dead Time to 50 from 20 seconds
941 Increase the Hard Dead Time to 120 from 40 seconds
942 (matches the Unix values)
944 * Fixed an assertion validating the number of allocated NCBs
946 * Fixed the build environment to consistently build for
947 Windows 2000 and above. (APPVER = 5.0)
949 * Fixed rx_debug to properly validate the receipt in incoming
950 data with select() and recvfrom(). Do not copy data out of
951 the socket buffer unless success is indicated.
954 * afsd_service.exe will now display a message box to the
955 desktop when it terminates due to an IP Address Change.
957 * installer no longer deletes AFS Server configuration data
960 * installer generates a warning dialog if the RPC service
961 is not properly configured
963 * installer compressed with lzma instead of bzip2
965 * afsd_service.exe shutdown crash solved once and for all
967 * reference counting of smb_vc_t data structures improved
969 * name space collision of smb_fid_t event objects corrected
971 * the output of "fs memdump" is now written to
972 %WINDIR%\TEMP\afsd_alloc.log
974 * the file TaAfsApp_1033.dll is now properly installed allowing
975 the User Manager to start
977 * a new algorithm is used for computing filename pattern matches
979 * afscreds.exe now accepts user names containing instance
982 * Fix the Directory Name Lookup Cache to be case-sensitive.
983 This is crucial in environments in which a Windows client
984 is accessing a directory with more than one filename that
985 differs only by case. If the directory contains "FOO"
986 and "Foo". You want "DEL Foo" to delete the correct one.
987 We still have a problem in that "DEL foo" will delete a
988 random filename. This will be addressed in a future release.
990 * Fix afscreds.exe -M option (renewMaps) to work when High
991 Security mode is off. Also, remember to disable the ActiveMap
992 flag in afsdsbmt.ini when a drive mapping is removed.
994 * Updates to NSIS installer script. AFS Server configuration
995 data will not be destroyed on un-install or re-install.
996 Use a better compression algorithm.
998 * afslogon.dll now uses KFW to obtain tokens when available
1000 * afslogon.dll when given an all uppercase username will
1001 attempt to authenticate with both the uppercase name
1002 and an all lowercase variation
1004 * DST modification removed. The fix appears to make things
1005 worse after a reboot of the machine.
1007 * fs.exe: added "cscpolicy" which is used to
1008 change client side caching policy for AFS shares
1010 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
1011 [-documents] [-disable] [-help]
1013 * Several uninitialized variables have been initialized
1015 * It is now possible to obtain tokens using cross realm
1016 Kerberos within afscreds.exe:
1018 user: jaltman@ATHENA.MIT.EDU
1020 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
1021 will will in turn be used to obtain afs@DEMENTIA.ORG.
1022 The resulting token will be stored with the display name
1023 jaltman@ATHENA.MIT.EDU@dementia.org
1025 * aklog.exe has been added to the client
1027 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
1028 [[-p | -path] pathname]
1032 -d gives debugging information.
1033 krb_realm is the kerberos realm of a cell.
1034 pathname is the name of a directory to which you wish to authenticate.
1035 -noprdb means don't try to determine AFS ID.
1036 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
1037 (default is Kerberos V)
1038 No commandline arguments means authenticate to the local cell.
1041 * All of the resource files have been restructured to adhere to
1042 a set of rules IBM implemented for loading string resources.
1043 These rules had either been forgotten or were not discovered
1044 by folks working on the OpenAFS sources. The end result was
1045 memory corruption. This is primary item which was preventing
1046 the AFS Server from working.
1048 * Increased the size of the maximum ticket size stored in a token
1049 from 344 bytes to 12,000. Increased the buffers used to convey
1050 messages between the pioctl() caller and the SMB Server from
1051 1000 bytes to 12,512. The code appeared to have been writing
1052 above the top of the stack by quite a few number of bytes.
1053 (The increased ticket size is necessary for the next item.)
1055 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
1056 Instead the raw Kerberos 5 ticket is used in its entirety. This
1057 is extremely important as it allows us to use pure Kerberos 5 KDCs
1058 as the source of the AFS authentication. The use of up to 12,000 byte
1059 tickets will allow tickets produced by all versions of Microsoft
1060 Active Directory to be used.
1061 - create a user account.
1062 - designate it DES only
1064 - specify its UPN to be "afs@realm"
1065 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
1067 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
1068 is special when using long file names. (you must use "*.*" and not "*")
1069 Instead only enforce it when performing 8dot3 searches.
1071 * Fixed the DST problem with creation times being set one hour ahead
1073 * Fixed the problem when using \\afs\cell-alias. For example,
1074 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
1075 for the alias name; instead simply expand the name. One of the
1076 symptoms of this problem was a loss of acquired tokens.
1078 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
1079 of strings. (Only English strings provided.)
1081 * Fixed the installer to properly replace in use files.
1083 * Fixed the build system to cleanup generated component version files
1085 * The release build compiled with MSVC 6.0 compiler to avoid the
1086 afsd_service.exe shutdown crash. This does not solve the problem
1087 but simply avoids it for the time being.
1091 * fix afslogon.dll to not corrupt memory when High Security mode
1094 * fix afsd_service.exe to not attempt to restore the stack when
1095 an exception occurs. (not safe in multi-threaded programs)
1097 * fix uninstaller to properly remove the CRT and MFC DLLs
1099 * remove a Message Box from afscreds.exe when getcellconfig()
1100 fails on a kerberos realm which is not a cell
1102 The following is a list of changes to the OpenAFS for Window client
1105 * "fs setserverprefs" will leave afsd service deadlocked
1107 * "vos listaddrs" will core dump
1109 * installer sets the appropriate keys to support Integrated Logon
1111 * installer disables the "Find Lana by Name" functionality as it
1112 was causing headaches for many users
1114 * fix the intermittent crash of the power management thread when
1115 shutting down the AFS Client Service
1117 * optimizes the obtain drive mount list functionality which is
1118 executed every time the mount tab in afscreds.exe and afs_config.exe
1119 are refreshed. (this happens a lot)
1121 * fix the service shutdown logic. add the STOP_PENDING state
1122 and do not accept additional service events after we declare
1125 The following is a list of changes to the OpenAFS for Window client
1128 * flexelint was run against the source tree and hundreds (perhaps
1129 thousands) of corrections were applied to ensure prototypes
1130 were in use; types were used consistently; variables were
1131 initialized; unused variables were removed; etc.
1133 * A wide variety of instrumentation was added including the
1134 ability to produce a stack trace from within afsd_service.exe
1137 * Dynamic configuration of the RDRtimeout value based upon the
1138 LanMan Workstation Session Timeout
1140 * The mount root no longer needs to be called "/afs". This
1141 is now set by a registry value "MountRoot" within the key
1142 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1144 * The cell list is now only read out of afsdcell.ini when the
1145 file changes instead of each time a cell is resolved.
1147 * Thread synchronization was added to cm_server.c and ktc_nt.c
1149 * All calls to GlobalAlloc()/GlobalFree() were replaced with
1150 calloc()/free(). The Global functions were needed on Windows 3.x
1151 but have caused a variety of problems on the Win32 platforms.
1152 Avoiding them is highly recommended by several Microsoft
1153 Knowledgebase articles
1155 * Support for Symbolic Links added to the AFS Shell Extension
1157 * Added a registry value "OverlayEnabled" to determine if
1158 Shell Extension Overlays should be enabled.
1159 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
1161 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
1162 separate trees for checked and free builds. Build system supports
1163 a custom directory src\WINNT\extra which can be used as a grafting
1164 location of organization specific additions to the build tree.
1166 * New installer built using NSIS 2.0.
1168 * Named all kernel objects in order to allow them to be monitored
1169 with tools such as SysInternals' ProcExp.exe.
1171 * Introduced new EventLog framework for AFSD
1173 * Introduced Power Management interface to AFSD for Standby and
1174 Hibernate modes to allow cache to be flushed prior to network
1177 * Utilize Win32 DNSQuery API instead of internal routines. This
1178 allows DNS SRV queries to be sent to all current domain name
1179 servers. Not just one specified in an INI file. DNS is now
1182 * "NetbiosName" registry value may be used to specify a fixed
1183 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
1184 when the loopback adapter is in use. If you need to use the
1185 old notation with a loopback adapter installed specify a registry
1188 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
1190 * Refactor all modules which depend on LAN Adapter and NetbiosName
1191 determination in a new library: lanahelper.lib. This allows for
1192 consistent behavior throughout the product.
1194 * Move the afsd.log and afsd_init.log files to the directory specified
1195 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
1196 for services. Added the Date to the log entries.
1198 * New registry value "RxMaxMTU" used to limit the size of the RX
1199 packets sent by the AFS Client Service to the Server. In order
1200 to enable OpenAFS to work across the Cisco IPSec VPN the packet
1201 size must be restricted to 1264 or smaller. The latest NSIS
1202 installer sets a value of 1260 by default.
1204 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
1205 packets. This is not needed in order to work across the Cisco
1206 VPN but might be needed for other network environments. This
1207 value is not set by the NSIS installer.
1209 * New registry value "HideDotFiles" is used to apply the Hidden
1210 attribute to files whose names begin with a '.'. This value
1211 is set by the NSIS installer.
1213 * New registry value "MaxMpxRequests" allows the maximum number
1214 of multiplexed sessions to be configured at run time. This
1215 value is not set by the NSIS installer. The default value is
1218 * New registry value "MaxVCPerServer" allows the maxmimum number
1219 of VCs per server to be configured at run time. This value is
1220 not set by the NSIS installer. The default value is 100.
1222 * New registry value "AllSubmount" allows the "all" submount to
1223 be disabled by setting its value to 0x00.
1225 * Allow cells names to be valid mount points
1226 \\<netbiosName>\<cellname>
1228 * Store the active state of drive mappings in order for afscreds.exe
1229 to restore them upon startup
1231 * Add exception handling to generate a Stack Trace to the afsd_init.log
1232 file if one happens to occur.
1234 * Add lots of logging to help detect the cause of invalid SMB packets
1236 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
1237 conversion of Kerberos 5 "afs" service tickets. Supports auto-
1238 renewal of expiring tokens as long as afscreds.exe is running.
1240 * New afscreds.exe command line options:
1242 -M = renew drive maps
1243 -N = ip address change detection
1246 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1247 determines whether or not MIT Kerberos for Windows should be used
1248 to obtain tokens via Kerberos 5 tickets.
1250 * New registry value "AfscredsShortcutParams" in
1251 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1252 determines the command line parameters to be specified when "fixing"
1253 the AFS Shortcut in the user's startup folder.
1255 * The "ShowTrayIcon" registry value has been moved from
1256 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1257 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
1259 * The <cell name> registry values used to store the token expiration
1260 reminders have been moved from
1261 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
1262 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
1264 * Obtain the Logon User Name from the Explorer key when available
1266 * new text document doc\txt\winnotes\registry.txt lists all registry
1267 values used by OpenAFS (excluding the AFS Server)
1269 * BUG: rx_securityClass objects were not properly reference
1270 counted and were never freed.
1272 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
1273 would be generated. The existence of a server does not imply
1274 that it is not down. If all of the servers for a cell are down
1275 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
1278 * BUG: the directory name lookup cache failed to free the entries
1279 in the cache when the name cache entries cycled. The entries
1280 in the cache would become dereferenced without being freed.
1282 * BUG: fs setserverprefs could be executed without Administrator
1285 * BUG: the number of allocated NCB objects (100) exceeded the number
1286 which could actually be waited upon by the kernel (64). Any objects
1287 which were utilized above the limit could never have event completions
1290 * BUG: smb_username_t objects were not being reference counted and
1291 were not properly freed.
1293 * BUG: smb_tid_t objects could under unusual circumstances be freed
1294 before they were no longer referenced.
1296 * BUG: smb_fid_t object pointer were frequently used even when
1297 their value could be NULL. They were not properly released and
1298 therefore they were never freed.
1300 * BUG: smb_packet_t data structures were not completely initialized
1303 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1304 Denied" because that causes the Explorer Shell to try again until
1305 access is obtained. Instead return "Remote Resources" which allows
1306 the shell to move on and treat the error as transient.
1308 * BUG: when initializing the NCBreturns structure, separate Event objects
1309 were created for each NCB although a single Event object was supposed
1310 to be shared by all.
1312 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1315 * BUG: smb_tran2Packet_t objects were not being properly referenced
1318 * BUG: directory path creation did not handle the case of multiple
1319 directories requiring creation in one attempt
1321 * BUG: SMB requests which required an Extended Response were ignored.
1322 This prevented some files from being written to AFS volumes.
1324 * BUG: character strings were being freed even after they were
1325 inserted into in use data structures
1327 * BUG: inconsistent usernames were used when High Security mode was
1328 enabled. (there is still much to do in this area)
1330 * BUG: pioctl() calls which require out of band RPC operations were
1331 susceptible to race conditions when performed by multiple processes
1333 * BUG: memory allocation and deallocation crossed instances of the
1334 C Runtime Library producing memory leakage and corruption in
1335 afscreds and the client configurator.
