2 * Added a new registry value, "StoreAnsiFilenames", which can be used
3 to force the use of ANSI character sets instead of OEM Code Pages.
4 This feature is useful when users require the ability to create
5 filenames with 8-bit characters and need to access the files from
6 both Latin-1 based Unix systems as well as from Windows.
8 Activation of this feature will prevent access to files stored with
11 * Shutdown all SMB threads in a synchronized manner when stopping the
14 * There is currently a maximum cache size of 1.3GB. The limit is imposed
15 by the largest contiguous block of unused memory within the 2GB process
16 space which can be assigned to the memory mapped file. Unfortunately,
17 when the executable digital signature verification code is activated
18 Windows sees fit to further segment the process memory which in turn
19 reduces the size of the maximum cache file to less then 800MB. If
20 larger cache sizes are desired, a new registry value should be set:
22 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
24 Setting this value will disable the runtime verification of digital
25 signatures on afsd_service.exe and the afs dlls which it loads. It
26 will not disable the the version number check on those same files.
27 The signature verification is not a security messure and is only meant
28 to enhance the ability to afsd_service.exe to detect potential
29 destablizing mixtures of DLLs from incompatible distributions.
31 Added code to auto-disable the signature verification check if
32 the desired cache size is greater then 700MB.
34 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
35 used to verify the validity of the afsd_service.exe binary
36 as well as each of the AFS DLLs loaded by the service. Not only
37 must the digital signature be valid but the signatures of the
38 DLL must be signed by the same entity as the service.
40 * Implement new functions: cm_freelanceMountPointExists and
41 cm_freelanceSymlinkExists. Use them along with other validity
42 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
43 ensure that name collisions do not occur and that empty strings
44 are not valid file names.
46 A symlink may not have a name which would resolve to a valid
47 cell name. Doing so would prevent access to the cell.
49 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
50 re-initialization code. The reference counts of the fake root.afs
51 volume scache object(s) would become invalid when the mount point
52 or symlink lists were altered.
54 * Add registry entries to provide mappings from the afsdsbmt.ini
55 to the new locations for applications which count on the use
56 of the old Profile file APIs. These apps are likely to fail
57 if the user does not have administrator privileges and the
58 registry is locked down.
60 * The afs_config.exe submounts dialog had two errors.
61 First, attempts to remove entries failed because the registry
62 key was being opened without KEY_WRITE privileges.
63 Second, when editing a submount entry, changing the name
64 would add a new key and leave the original one in place.
65 Now the original submount will be removed if its name is
68 * In recent months there have been several incidents in which
69 users have experienced problems starting or accessing
70 afsd_service.exe and after significant effort has been spent
71 it has turned out that they have two versions of AFS on the
72 machine or an inconsistent set of DLLs.
74 Code has now been added to afsd_service.exe which will walk
75 the list of modules loaded by afsd_service.exe and validate
76 that the version of the AFS DLLs matches the version of the
77 afsd_service.exe executable. If they do not match the service
80 * When Freelance mode is enabled and there is no registry
81 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
82 will attempt to import the afs_freelance.ini file contents.
83 If the file does not exist, it was creating a dummy file
84 with a r/o and r/w entry for the default cell and then
85 importing those values.
87 This process has been changed. The temporary file is no
88 longer created. Also, both the OpenAFS Client install
89 directory as well as %WINDIR% are checked for previous
90 afs_freelance.ini files.
92 * Added support for VL_GetEntryByNameN(). Still need to add
93 support for VL_GetEntryByNameU() for multi-homed support.
95 * Fix a deadlock situation in afscreds.exe when canceling an
96 auto-generated Obtain Tokens dialog
99 * Fix the locking of objects during Directory Searches in the
100 SMB/CIFS server. The failure to properly lock the reference
101 counts was resulting in the premature freeing of smb_dirSearch_t
102 objects while they were still in use by the SMB/CIFS client.
103 This does not solve the "Invalid Handle" problem.
105 * Fix Find Cell By Name pioctl call to return a valid cell
106 name for the Freelance fake root.afs volume.
107 "Freelance.Local.Root".
109 * Fix the Explorer Shell Extension Symlinks->Add operation.
110 The dialog template was missing and the link destination
111 string was too short.
113 * Add support for symlinks to Freelance root.afs volume
114 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
115 <number> = "<linkname>:<relative-path>."
116 Use symlink.exe to create, list, or remove
118 * Remove the fallback to the use of KFW's KRB4 library when obtaining
119 tokens. We never obtain KRB4 tickets.
121 * Fix AFS Client Configuration Control Panel to support new SysName
123 * Fix a bug in afsd_service.exe which could result in the SysName
124 not being read from the registry.
127 * Add code to block the issuance of AFS tokens by aklog.exe or
128 afscreds.exe when the Kerberos 5 principal name contains a dot.
130 * Modify the IsAdmin() function to always treat the local SYSTEM
131 account as an AFS client administrator. Affects fs.exe and
134 * Modify the internal handling of Quota Exceeded errors
136 * Upgrade all reference count fields in the Windows cache manager
137 and the osi library to use unsigned long instead of signed short.
138 A similar fix has been applied to the afs rpc (rx) library.
140 * fix the Windows cache manager to prevent it from replacing the
141 rx_connection object associated with the cm_conn_t object on each
142 and every operation if "fs crypt" was set. This explains the
143 dramatic performance difference when crypt is used vs clear.
144 The problem: 'cryptall', a boolean flag indicating whether or not
145 "fs crypt" is set, was being compared to the rx_connection
146 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
147 1 != 2 and therefore the rx_connection was always destroyed
148 and replaced on each and every operation.
150 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
151 It is not safe for the cm_conn_t object to not be locked because
152 rx_DestroyConnection might be called from another thread if:
153 - the user's tokens have changed or expired
154 - the crypt mode has changed
156 This fix appears to have also taken care of the problems associated
157 with Overlapped Writes resulting in Delayed Write errors.
159 * fix NSIS installer's AdminGroup.exe to properly create and
160 remove groups when given -create or -remove. The string comparison
163 * fs sysname now accepts a list of sysname values
165 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
166 DWORD which when set to a non-zero value will cause error message
167 text to be output to stderr from the pioctl() routine. Useful in
168 debugging failures of fs.exe, tokens.exe, etc.
170 * added a test to the power management code to only perform a
171 flush operation if there is at least one network adapter which
172 is not a loopback adapter.
174 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
175 "EnableKFW". This value will not be read if the key
176 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
177 value under that key does not.
179 * provide mechanisms to force the use of krb524d for Kerberos 5
180 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
181 there is a new registry value "Use524" and for aklog.exe a new
182 command line parameter "-m".
184 * Fix the pattern matching algorithm to properly match patterns
187 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
188 which is used by both the original function and the new
189 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
190 creation of HardLinks in addition to Renaming. smb_Link()
191 is a new function which creates HardLinks via cm_Link().
192 cm_Link() is a new vnodeops function which creates links
195 smb_ReceiveNTRename() does not support the File Copy and
196 Move Cluster Information operations described in its interface.
197 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
199 * When opening files via symlinks, we should follow the symlinks
200 until we reach the actual file stat cache entry. The stat cache
201 entry of the file should then be stored in the FID instead of
202 stat scache entry of the symlink.
204 * return bad operation errors for all unimplemented functions
205 even if we do not know the functions exist.
207 * Log bad packets and unknown operation packets to the trace log
209 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
212 * Update list of known CIFS operations to include all those listed
213 in CIFS-TR-1p00_FINAL.pdf.
215 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
216 to support the REG_EXPAND_SZ type.
219 * A new Windows authorization group "AFS Client Admins" is now
220 created and populated with the members of the "Administrators"
221 group. The group is used to determine which accounts on the
222 machine may be used to modify the AFS Client Configuration via
223 the UI and command line tools. afs_config.exe, fs.exe,
225 * Modify the WinLogon Logoff Event Handler to query NT4 domain
226 controllers for the remote profile path if Active Directory
227 services are not available.
229 * Fix aklog.exe to not add the AFS ID to the username
231 * PTS registration of new users to foreign cells has been added to
234 * The cm_Daemon thread is used to perform checks for
235 down servers, up servers, volumes, callback expirations,
236 lock maintenance and token expiration. Due to a gaff in
237 larger integer division the thread never performed any
238 work. Instead the current time computation would always
239 be less then the trigger times. This had an adverse affect
240 on the client's ability to maintain communication with servers,
241 keep volumes up to date, and flush user tokens and acls
242 when they have expired. This was broken when the 1.3 branch
243 was modified to support VC7 which no longer included
246 * An initialization problem with the Freelance code was
247 detected while fixing the callbackRequest. The cm_rootSCachep
248 object is obtained during afsd_InitDaemons() but the callback
249 information is incomplete. The callback information will not
250 be obtained until cm_MergeStatus is called from within
251 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
252 test for the conditions under which the callback information
255 * Reports have been filed indicating that callbacks were
256 being lost. An examination of the code indicated that the
257 cm_server_t objects were not being properly reference
258 counted by the cm_scache_t and cm_callbackRequest_t objects.
259 In particular, the cm_server_t objects may have been freed
260 from beneath the cm_conn_t objects.
262 All of the reference counting is now done via the functions:
267 this improves the ability to track the referrals.
269 Each cm_BeginCallbackGranting Call now allocates a reference
270 to the cm_server_t. The cm_EndCallbackGrantingCall either
271 frees the reference or transfers it to the cm_scache_t
272 cbServerp field. These are then appropriately tracked
273 through the cm_Analyze call.
275 * Ensure that the dnlc hash table is the same size as the
276 dir name hash table (as per original author's note).
277 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
278 for compatibility with 64-bit systems.
280 * fix smb_ApplyV3DirListPatches to properly apply the hidden
281 attribute to dotfiles when the infoLevel < 0x101 and
282 cm_SyncOp has failed.
284 * Fix the Freelance registry initialization code. There
285 was a possibility that some systems could end up with
286 garbage in the registry during a clean install.
289 * file and directory names beginning with "." will now be given the
290 hidden attribute when the volume access is anonymous. this matches
291 the behavior when the volume access is via an authenticated user.
293 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
294 key. When a change occurs mark the root.afs data as invalid and
295 for it to be reloaded on the next access. This allows administrators
296 to modify the mount point list without restarting the service.
298 The freelance client used to provide a fake modification time for
299 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
300 Added code to extract the last modification time of the Freelance
301 registry key and use that instead. The time now represents the
302 most recent mount point change.
304 * PTS registration of new users to foreign cells has been added to
307 * Additional Cache Control and Credential Manager options have been
308 added to the WiX installer. See deployment guide for details.
310 * The CachePath setting is now optionally a REG_EXPAND_SZ type
312 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
315 * The loopback installation code may have had a problem updating the
316 %ETC%\HOSTS file which could have resulted in a premature failure.
317 Work around code has been added for the case where the file cannot
320 * The default max chunksize was increased from 15 (32K) to 17 (128K)
321 because Windows sends 64K blocks when using overlapped writes.
323 * The default number of server threads was increased from 4 to 25 to
324 better handle overlapped writes.
326 * The "AfscredsShortcutParams" registry value was not being properly
327 loaded by afscreds.exe. Therefore, the default value was always being
328 used instead of the value set by the installer.
330 * Windows XP provides downgrade attack detection to prevent an attacker
331 from being able to force the use of NTLM simply by disrupting
332 communication with the KDC. This attack cannot exist between the
333 Windows CIFS client and the AFS Client Service. Therefore, when a
334 downgrade has been detected the afs pioctl library will force the
335 establishment of a new CIFS connection using NTLM.
337 * A locking error was discovered surrounding all references to volume
338 server lists within the cm_cell.c source file.
340 * The logged into Windows username was incorrect on Terminal Server
343 * A new registry value "NonPersistentCaching" was added to the service
344 parameters key. When set to a non-zero value, the afs cache is stored
345 in the Windows paging file. There are two limitations to choosing
347 1. when persistent caching is implemented it won't work with
348 this flag set since there will be nothing to persist.
349 2. with this flag set the initial paging allocation cannot be
350 changed while the service is running
352 * An initialization bug was discovered in aklog.exe which affected users
353 who have a domain name for their afs servers which could not be mapped
357 * afs_config.exe now validates cell names against DNS in addition
358 to the CellServDB file.
360 * In order to allow the freelance client to connect to a volume with ID
361 equal to 1 on the default cell we changed the fake root.afs volume ID
362 once again. This time we choose 0xFFFFFFFF. In addition, we change
363 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
364 It will now be impossible for a volume ID to match that of another
365 cell unless the client is connected to 0xFFFFFFFD cells. That should
366 be enough room for growth.
368 * Fix "fs mkmount" command to work with UNC paths and when
369 started from non-AFS drives. It is now possible to create a mount
370 point in the freelance fake root.afs volume with the command
372 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
376 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
377 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
379 * The algorithm used to re-attempt access to the servers associated with
380 a volume has been altered to properly address the case in which all
381 servers have been marked down. The previous algorithm did not reset
382 the server's down flags so the servers were never actually retried.
383 This caused a problem with active volumes if the network connectivity
384 was lost as could be the case with a network cable removal, wireless
385 drop, or laptop hibernation. With the fix volume access is restored
386 almost instantenously when network connectivity becomes available.
388 * Support for SMB/CIFS browsing has been added to the AFS Client Service
389 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
390 listing of AFS submounts and freelance mount points. Support for
391 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
392 significantly enhances the behavior of AFS volumes within the Explorer
393 Shell. For instance, "AFS" now shows up as server in the Explorer
394 with each submount or freelance mount point visible as a share.
395 The right click menu in each folder now works with full functionality
396 on a consistent basis.
398 * The network provider can be configured to have different behavior
399 depending on the domain that the user logs into. These settings are
400 only relevant when using integrated login. A domain refers to an
401 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
402 local machine (i.e. local account logins). The domain name that is
403 used for selecting the domain would be the domain that is passed into
404 the NPLogonNotify function of the network provider. (see registry.txt
407 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
408 "Authentication Cell" which may be used to specify a default
409 authentication cell for afscreds.exe which is different from
410 the default cell for the AFS Client Service daemon.
412 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
413 afslogon.dll moved to %WINDIR%\System32\.
414 New registry entries added to register the dll for Winlogon events.
416 The logoff event will now force a call to ktc_ForgetAllTokens()
417 using the context of the user being logged off as long as the
418 user's profile is not loaded from within AFS. If the profile
419 was loaded from AFS we can't release the tokens since the Logoff
420 event is triggered prior to the profile being written back to
421 the its source location. This is now performed in an XP SP2
424 * Windows XP SP2 Internet Connection Firewall interoperability
427 * The %WINDIR%\afsdsbmt.ini contains four sections:
428 Submounts, Drive Mappings, Active Maps and CSC Policies.
429 The Submounts and CSC policies are now stored in the registry under
430 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
431 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
432 The Drive Mappings and Active Maps are stored in the registry under
433 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
434 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
436 There is no automatic migration of this data as it would be impossible
437 to consistently migrate data to user profiles which may not be active
438 when the machine is updated.
440 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
441 fake root.afs volume. For the same reasons as for the cellservdb file,
442 this information should not be in %WINDIR%. This information is now
443 kept under the registry key
444 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
446 The data from the afs_freelance.ini file will be automatically
447 migrated to the registry on first execution of afsd_service.exe
449 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
450 troublesome for several reasons. One, it is confusing for those who
451 expect the file to be named "CellServDB" instead of "afsdcell.ini".
452 Two, this file is not a Windows Profile formatted file. Three,
453 applications should not be reading or writing to %WINDIR%. It causes
454 problems for Windows Terminal Server.
456 The new location of CellServDB will be the OpenAFS Client install
457 directory which is by default C:\Program Files\OpenAFS\Client and can
458 be determined by querying the registry for
459 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
461 The existing afsdcell.ini will be migrated by the NSIS installer.
462 The Wix installer must still be updated to do the same.
464 * Change NSIS installer to use DNS by default; to remove Integrated Logon
465 High Security mode; and to add Terminal Services compatibility registry
466 entries to allow the OpenAFS tools to find the afsdcell.ini and other
467 configuration files in %WINDIR%.
469 * Add support for authenticated SMB connections. This will remove
470 the need for high security mode in most situations. Both NTLM
471 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
472 only NTLM can be used even though Kerberos is now supported. The
473 reason is that it is not possible to construct a service principal
474 which is unique to each individual machine.
476 SMB Extended Auth does not work on XP SP2 unless one of two registry
477 modifications are made:
479 (1) To disable the check for matching host names on loopback connections
480 set this key. This does not require a reboot:
482 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
483 "DisableLoopbackCheck"=dword:00000001
485 (2) To add the AFS SMB/CIFS service name to an approved list. This
486 does require a reboot:
488 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
489 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
491 afsd_service.exe will automatically add the current Netbios Name
492 to the BackConnectionHostNames list and then temporarily disable
493 the loopback check for one cycle of startup/shutdown of the service.
494 We assume most folks do not start/stop without a reboot so this
495 will be adequate in most cases.
497 * Fix security hole in afslogon.dll which allowed passwords to be
498 sent in clear text to the KDC in a misformed principal name.
500 * Fix cm_GetCell() to properly handle expired dns entries
503 * If Freelance mode is active and the afs_freelance.ini
504 file does not exist, do not create an empty file.
505 Instead create a file containing ro and rw mountpoints
506 to the default cell using the standard conventions.
508 * Modify the Freelance support to handle the ability
509 to create rw mount points in the fake root.afs volume.
511 * Changed the RPC mechanism used for token setting from
512 named pipes to local. Use of named pipes can be restored
513 by setting the environment variable AFS_RPC_PROTSEQ to
516 Named pipes were required when a Windows 9x system was
517 using a NT system in gateway mode which is incompatible
518 with our use of local loopback adapters.
520 * In afscreds.exe, if a username of the form user@REALM is
521 specified and no password is specified, do not perform a
522 kinit operation. Only perform the aklog functionality.
524 * Add a new registry value which allows the number of processors
525 on which afsd_service.exe executes to be restricted. Valid
526 values are 1..numOfProcessors
528 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
532 * A second MSI based installer option is now available.
534 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
535 request tickets for user/instance@REALM instead of just user@REALM
537 * Modify the Power Management Notify routine to wait for the Hard Dead
538 timeout period instead of a fixed 19 seconds. With the longer timeout
539 periods Hibernation and Standby could never succeed when network
540 connectivity is not available.
542 * The following fs.exe commands are now restricted to Administrator:
543 - checkservers with a non-zero timer value
546 - sysname with a new sysname list
555 setting the default sysname for a machine should be done via the
556 registry and not via "fs sysname".
558 * NSIS installer adds options to install Debugging Symbols
559 and the Microsoft Loopback Adapter; the user is now also
560 given the ability to select the afscreds.exe startup options.
562 * Build system modified to generate symbols for FREE (aka RELEASE)
563 builds as well as CHECKED (aka DEBUG) builds
565 * Sites which have a volume ID of 0x20000001 assigned to their
566 root.cell volumes have been experiencing problems with accessing
567 the root.cell volume of their cell when Freelance mode has been
568 active. This was because 0x20000001 was assigned to the fake
569 root.afs volume created by freelance. The fake volume id is
570 now set to 0x00000001 to prevent conflicts.
572 * The timeout logic in the AFS Client Service has been wrong
573 for sometime. It is based on two different assumptions.
574 First, the SMB client timeout is a fix value as was the case
575 with OS/2 Lan Manager. This assumption is incorrect. The
576 SMB timeout in Windows is a dynamic value computed based upon
577 a fixed minimum timeout to which is added time based upon the
578 size of the request and the performance characteristics of
579 the connection. Second, it is the responsibility of the
580 SMB Server to enforce the timeout requirements of the client.
581 This is untrue. The SMB Server cannot be expected to know
582 the requirements of the client. More importantly, if the
583 SMB server uses the SMB client timeout as a value to restrict
584 its behavior as an RX client, the performance characteristics
585 of the local SMB session would be used to prematurely terminate
586 WAN connections with significantly different performance
589 The timeout logic has therefore been modified in the following
591 . the Lan Manager Workstation (SMB) Session Timeout is used only
592 as a basis for configuring the Connection Dead Timeout
593 and Hard Dead Timeout values. The Connection Dead Timeout
594 must be at least 15 seconds longer than the SMB Timeout
595 and the Hard Dead Timeout must be at least double the
596 Connection Dead Timeout.
597 . New registry entries have been added to allow the Connection
598 Dead Timeout and Hard Dead Timeout values independent of the
599 Lan Manager Workstation Session Timeout
600 . The test to enforce the SMB Client Timeout has been removed.
602 One of the side-effects of removing the enforcement of the SMB
603 Client Timeout is that regardless of whether or not the SMB client
604 is available to receive the response (and how would the SMB server
605 know) the RX protocol response can be used to update the AFS
606 Client Service state for ready access by future SMB client
609 This should be the end of the "Server paused or restarting messages"
611 * Add support for arbitrary UNC paths to the pioctl() support.
612 This enables the fs commands as well as the AFS Shell Extension
613 to work correctly when UNC paths are being used.
615 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
616 DNS if the cell configuration cannot be determined via CellServDB
618 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
619 are ever set more than once at a time
621 * Fix the management of lists of cm_cell_t structures when using
622 DNS to lookup cell information. The previous code would fail to
623 reuse the same cellID for a cell if DNS was used more than once
624 for a given cell name. When the ttl expired, a single cm_cell_t
625 could be inserted into the cm_allCellsp list more than once
626 producing a loop. In addition, the vlServerp list belonging to
627 the cell was not freed resulting in improper refCounting of the
630 * Add DNS support to cm_IoctlNewCell() which previous only examined
633 * Add cm_FreeServer() function and call it from cm_FreeServerList()
634 to properly garbage collect cm_server_t objects
636 * Add numVCs variable to smb.c to track the number of smb_vc_t
637 objects created and use it to initialize the vcID field which
638 previously was set to 0 in all objects resulting in FindByID
641 * Fixed DNS lookups to work consistently throughout the OpenAFS
642 product instead of just from within the afsd_service.exe
644 * Added a runtime check to ensure that AFS Client Service SMB
645 Server is accepting connections before attempting to mount
648 * Read IP addresses for volume servers out of the CellServDB
649 file if gethostbyname() on the hostname fails.
651 * Fix getcellconfig() to populate both the Hostnames as well
652 as IP addresses when loading cell data via DNS
654 * Increase the Connection Dead Time to 50 from 20 seconds
655 Increase the Hard Dead Time to 120 from 40 seconds
656 (matches the Unix values)
658 * Fixed an assertion validating the number of allocated NCBs
660 * Fixed the build environment to consistently build for
661 Windows 2000 and above. (APPVER = 5.0)
663 * Fixed rx_debug to properly validate the receipt in incoming
664 data with select() and recvfrom(). Do not copy data out of
665 the socket buffer unless success is indicated.
668 * afsd_service.exe will now display a message box to the
669 desktop when it terminates due to an IP Address Change.
671 * installer no longer deletes AFS Server configuration data
674 * installer generates a warning dialog if the RPC service
675 is not properly configured
677 * installer compressed with lzma instead of bzip2
679 * afsd_service.exe shutdown crash solved once and for all
681 * reference counting of smb_vc_t data structures improved
683 * name space collision of smb_fid_t event objects corrected
685 * the output of "fs memdump" is now written to
686 %WINDIR%\TEMP\afsd_alloc.log
688 * the file TaAfsApp_1033.dll is now properly installed allowing
689 the User Manager to start
691 * a new algorithm is used for computing filename pattern matches
693 * afscreds.exe now accepts user names containing instance
696 * Fix the Directory Name Lookup Cache to be case-sensitive.
697 This is crucial in environments in which a Windows client
698 is accessing a directory with more than one filename that
699 differs only by case. If the directory contains "FOO"
700 and "Foo". You want "DEL Foo" to delete the correct one.
701 We still have a problem in that "DEL foo" will delete a
702 random filename. This will be addressed in a future release.
704 * Fix afscreds.exe -M option (renewMaps) to work when High
705 Security mode is off. Also, remember to disable the ActiveMap
706 flag in afsdsbmt.ini when a drive mapping is removed.
708 * Updates to NSIS installer script. AFS Server configuration
709 data will not be destroyed on un-install or re-install.
710 Use a better compression algorithm.
712 * afslogon.dll now uses KFW to obtain tokens when available
714 * afslogon.dll when given an all uppercase username will
715 attempt to authenticate with both the uppercase name
716 and an all lowercase variation
718 * DST modification removed. The fix appears to make things
719 worse after a reboot of the machine.
721 * fs.exe: added "cscpolicy" which is used to
722 change client side caching policy for AFS shares
724 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
725 [-documents] [-disable] [-help]
727 * Several uninitialized variables have been initialized
729 * It is now possible to obtain tokens using cross realm
730 Kerberos within afscreds.exe:
732 user: jaltman@ATHENA.MIT.EDU
734 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
735 will will in turn be used to obtain afs@DEMENTIA.ORG.
736 The resulting token will be stored with the display name
737 jaltman@ATHENA.MIT.EDU@dementia.org
739 * aklog.exe has been added to the client
741 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
742 [[-p | -path] pathname]
746 -d gives debugging information.
747 krb_realm is the kerberos realm of a cell.
748 pathname is the name of a directory to which you wish to authenticate.
749 -noprdb means don't try to determine AFS ID.
750 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
751 (default is Kerberos V)
752 No commandline arguments means authenticate to the local cell.
755 * All of the resource files have been restructured to adhere to
756 a set of rules IBM implemented for loading string resources.
757 These rules had either been forgotten or were not discovered
758 by folks working on the OpenAFS sources. The end result was
759 memory corruption. This is primary item which was preventing
760 the AFS Server from working.
762 * Increased the size of the maximum ticket size stored in a token
763 from 344 bytes to 12,000. Increased the buffers used to convey
764 messages between the pioctl() caller and the SMB Server from
765 1000 bytes to 12,512. The code appeared to have been writing
766 above the top of the stack by quite a few number of bytes.
767 (The increased ticket size is necessary for the next item.)
769 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
770 Instead the raw Kerberos 5 ticket is used in its entirety. This
771 is extremely important as it allows us to use pure Kerberos 5 KDCs
772 as the source of the AFS authentication. The use of up to 12,000 byte
773 tickets will allow tickets produced by all versions of Microsoft
774 Active Directory to be used.
775 - create a user account.
776 - designate it DES only
778 - specify its UPN to be "afs@realm"
779 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
781 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
782 is special when using long file names. (you must use "*.*" and not "*")
783 Instead only enforce it when performing 8dot3 searches.
785 * Fixed the DST problem with creation times being set one hour ahead
787 * Fixed the problem when using \\afs\cell-alias. For example,
788 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
789 for the alias name; instead simply expand the name. One of the
790 symptoms of this problem was a loss of acquired tokens.
792 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
793 of strings. (Only English strings provided.)
795 * Fixed the installer to properly replace in use files.
797 * Fixed the build system to cleanup generated component version files
799 * The release build compiled with MSVC 6.0 compiler to avoid the
800 afsd_service.exe shutdown crash. This does not solve the problem
801 but simply avoids it for the time being.
805 * fix afslogon.dll to not corrupt memory when High Security mode
808 * fix afsd_service.exe to not attempt to restore the stack when
809 an exception occurs. (not safe in multi-threaded programs)
811 * fix uninstaller to properly remove the CRT and MFC DLLs
813 * remove a Message Box from afscreds.exe when getcellconfig()
814 fails on a kerberos realm which is not a cell
816 The following is a list of changes to the OpenAFS for Window client
819 * "fs setserverprefs" will leave afsd service deadlocked
821 * "vos listaddrs" will core dump
823 * installer sets the appropriate keys to support Integrated Logon
825 * installer disables the "Find Lana by Name" functionality as it
826 was causing headaches for many users
828 * fix the intermittent crash of the power management thread when
829 shutting down the AFS Client Service
831 * optimizes the obtain drive mount list functionality which is
832 executed every time the mount tab in afscreds.exe and afs_config.exe
833 are refreshed. (this happens a lot)
835 * fix the service shutdown logic. add the STOP_PENDING state
836 and do not accept additional service events after we declare
839 The following is a list of changes to the OpenAFS for Window client
842 * flexelint was run against the source tree and hundreds (perhaps
843 thousands) of corrections were applied to ensure prototypes
844 were in use; types were used consistently; variables were
845 initialized; unused variables were removed; etc.
847 * A wide variety of instrumentation was added including the
848 ability to produce a stack trace from within afsd_service.exe
851 * Dynamic configuration of the RDRtimeout value based upon the
852 LanMan Workstation Session Timeout
854 * The mount root no longer needs to be called "/afs". This
855 is now set by a registry value "MountRoot" within the key
856 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
858 * The cell list is now only read out of afsdcell.ini when the
859 file changes instead of each time a cell is resolved.
861 * Thread synchronization was added to cm_server.c and ktc_nt.c
863 * All calls to GlobalAlloc()/GlobalFree() were replaced with
864 calloc()/free(). The Global functions were needed on Windows 3.x
865 but have caused a variety of problems on the Win32 platforms.
866 Avoiding them is highly recommended by several Microsoft
867 Knowledgebase articles
869 * Support for Symbolic Links added to the AFS Shell Extension
871 * Added a registry value "OverlayEnabled" to determine if
872 Shell Extension Overlays should be enabled.
873 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
875 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
876 separate trees for checked and free builds. Build system supports
877 a custom directory src\WINNT\extra which can be used as a grafting
878 location of organization specific additions to the build tree.
880 * New installer built using NSIS 2.0.
882 * Named all kernel objects in order to allow them to be monitored
883 with tools such as SysInternals' ProcExp.exe.
885 * Introduced new EventLog framework for AFSD
887 * Introduced Power Management interface to AFSD for Standby and
888 Hibernate modes to allow cache to be flushed prior to network
891 * Utilize Win32 DNSQuery API instead of internal routines. This
892 allows DNS SRV queries to be sent to all current domain name
893 servers. Not just one specified in an INI file. DNS is now
896 * "NetbiosName" registry value may be used to specify a fixed
897 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
898 when the loopback adapter is in use. If you need to use the
899 old notation with a loopback adapter installed specify a registry
902 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
904 * Refactor all modules which depend on LAN Adapter and NetbiosName
905 determination in a new library: lanahelper.lib. This allows for
906 consistent behavior throughout the product.
908 * Move the afsd.log and afsd_init.log files to the directory specified
909 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
910 for services. Added the Date to the log entries.
912 * New registry value "RxMaxMTU" used to limit the size of the RX
913 packets sent by the AFS Client Service to the Server. In order
914 to enable OpenAFS to work across the Cisco IPSec VPN the packet
915 size must be restricted to 1264 or smaller. The latest NSIS
916 installer sets a value of 1260 by default.
918 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
919 packets. This is not needed in order to work across the Cisco
920 VPN but might be needed for other network environments. This
921 value is not set by the NSIS installer.
923 * New registry value "HideDotFiles" is used to apply the Hidden
924 attribute to files whose names begin with a '.'. This value
925 is set by the NSIS installer.
927 * New registry value "MaxMpxRequests" allows the maximum number
928 of multiplexed sessions to be configured at run time. This
929 value is not set by the NSIS installer. The default value is
932 * New registry value "MaxVCPerServer" allows the maxmimum number
933 of VCs per server to be configured at run time. This value is
934 not set by the NSIS installer. The default value is 100.
936 * New registry value "AllSubmount" allows the "all" submount to
937 be disabled by setting its value to 0x00.
939 * Allow cells names to be valid mount points
940 \\<netbiosName>\<cellname>
942 * Store the active state of drive mappings in order for afscreds.exe
943 to restore them upon startup
945 * Add exception handling to generate a Stack Trace to the afsd_init.log
946 file if one happens to occur.
948 * Add lots of logging to help detect the cause of invalid SMB packets
950 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
951 conversion of Kerberos 5 "afs" service tickets. Supports auto-
952 renewal of expiring tokens as long as afscreds.exe is running.
954 * New afscreds.exe command line options:
956 -M = renew drive maps
957 -N = ip address change detection
960 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
961 determines whether or not MIT Kerberos for Windows should be used
962 to obtain tokens via Kerberos 5 tickets.
964 * New registry value "AfscredsShortcutParams" in
965 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
966 determines the command line parameters to be specified when "fixing"
967 the AFS Shortcut in the user's startup folder.
969 * The "ShowTrayIcon" registry value has been moved from
970 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
971 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
973 * The <cell name> registry values used to store the token expiration
974 reminders have been moved from
975 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
976 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
978 * Obtain the Logon User Name from the Explorer key when available
980 * new text document doc\txt\winnotes\registry.txt lists all registry
981 values used by OpenAFS (excluding the AFS Server)
983 * BUG: rx_securityClass objects were not properly reference
984 counted and were never freed.
986 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
987 would be generated. The existence of a server does not imply
988 that it is not down. If all of the servers for a cell are down
989 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
992 * BUG: the directory name lookup cache failed to free the entries
993 in the cache when the name cache entries cycled. The entries
994 in the cache would become dereferenced without being freed.
996 * BUG: fs setserverprefs could be executed without Administrator
999 * BUG: the number of allocated NCB objects (100) exceeded the number
1000 which could actually be waited upon by the kernel (64). Any objects
1001 which were utilized above the limit could never have event completions
1004 * BUG: smb_username_t objects were not being reference counted and
1005 were not properly freed.
1007 * BUG: smb_tid_t objects could under unusual circumstances be freed
1008 before they were no longer referenced.
1010 * BUG: smb_fid_t object pointer were frequently used even when
1011 their value could be NULL. They were not properly released and
1012 therefore they were never freed.
1014 * BUG: smb_packet_t data structures were not completely initialized
1017 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1018 Denied" because that causes the Explorer Shell to try again until
1019 access is obtained. Instead return "Remote Resources" which allows
1020 the shell to move on and treat the error as transient.
1022 * BUG: when initializing the NCBreturns structure, separate Event objects
1023 were created for each NCB although a single Event object was supposed
1024 to be shared by all.
1026 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1029 * BUG: smb_tran2Packet_t objects were not being properly referenced
1032 * BUG: directory path creation did not handle the case of multiple
1033 directories requiring creation in one attempt
1035 * BUG: SMB requests which required an Extended Response were ignored.
1036 This prevented some files from being written to AFS volumes.
1038 * BUG: character strings were being freed even after they were
1039 inserted into in use data structures
1041 * BUG: inconsistent usernames were used when High Security mode was
1042 enabled. (there is still much to do in this area)
1044 * BUG: pioctl() calls which require out of band RPC operations were
1045 susceptible to race conditions when performed by multiple processes
1047 * BUG: memory allocation and deallocation crossed instances of the
1048 C Runtime Library producing memory leakage and corruption in
1049 afscreds and the client configurator.
