2 * Add code to block the issuance of AFS tokens by aklog.exe or
3 afscreds.exe when the Kerberos 5 principal name contains a dot.
5 * Modify the IsAdmin() function to always treat the local SYSTEM
6 account as an AFS client administrator. Affects fs.exe and
9 * Modify the internal handling of Quota Exceeded errors
11 * Upgrade all reference count fields in the Windows cache manager
12 and the osi library to use unsigned long instead of signed short.
13 A similar fix has been applied to the afs rpc (rx) library.
15 * fix the Windows cache manager to prevent it from replacing the
16 rx_connection object associated with the cm_conn_t object on each
17 and every operation if "fs crypt" was set. This explains the
18 dramatic performance difference when crypt is used vs clear.
19 The problem: 'cryptall', a boolean flag indicating whether or not
20 "fs crypt" is set, was being compared to the rx_connection
21 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
22 1 != 2 and therefore the rx_connection was always destroyed
23 and replaced on each and every operation.
25 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
26 It is not safe for the cm_conn_t object to not be locked because
27 rx_DestroyConnection might be called from another thread if:
28 - the user's tokens have changed or expired
29 - the crypt mode has changed
31 This fix appears to have also taken care of the problems associated
32 with Overlapped Writes resulting in Delayed Write errors.
34 * fix NSIS installer's AdminGroup.exe to properly create and
35 remove groups when given -create or -remove. The string comparison
38 * fs sysname now accepts a list of sysname values
40 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
41 DWORD which when set to a non-zero value will cause error message
42 text to be output to stderr from the pioctl() routine. Useful in
43 debugging failures of fs.exe, tokens.exe, etc.
45 * added a test to the power management code to only perform a
46 flush operation if there is at least one network adapter which
47 is not a loopback adapter.
49 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
50 "EnableKFW". This value will not be read if the key
51 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
52 value under that key does not.
54 * provide mechanisms to force the use of krb524d for Kerberos 5
55 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
56 there is a new registry value "Use524" and for aklog.exe a new
57 command line parameter "-m".
59 * Fix the pattern matching algorithm to properly match patterns
62 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
63 which is used by both the original function and the new
64 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
65 creation of HardLinks in addition to Renaming. smb_Link()
66 is a new function which creates HardLinks via cm_Link().
67 cm_Link() is a new vnodeops function which creates links
70 smb_ReceiveNTRename() does not support the File Copy and
71 Move Cluster Information operations described in its interface.
72 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
74 * When opening files via symlinks, we should follow the symlinks
75 until we reach the actual file stat cache entry. The stat cache
76 entry of the file should then be stored in the FID instead of
77 stat scache entry of the symlink.
79 * return bad operation errors for all unimplemented functions
80 even if we do not know the functions exist.
82 * Log bad packets and unknown operation packets to the trace log
84 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
87 * Update list of known CIFS operations to include all those listed
88 in CIFS-TR-1p00_FINAL.pdf.
90 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
91 to support the REG_EXPAND_SZ type.
94 * A new Windows authorization group "AFS Client Admins" is now
95 created and populated with the members of the "Administrators"
96 group. The group is used to determine which accounts on the
97 machine may be used to modify the AFS Client Configuration via
98 the UI and command line tools. afs_config.exe, fs.exe,
100 * Modify the WinLogon Logoff Event Handler to query NT4 domain
101 controllers for the remote profile path if Active Directory
102 services are not available.
104 * Fix aklog.exe to not add the AFS ID to the username
106 * PTS registration of new users to foreign cells has been added to
109 * The cm_Daemon thread is used to perform checks for
110 down servers, up servers, volumes, callback expirations,
111 lock maintenance and token expiration. Due to a gaff in
112 larger integer division the thread never performed any
113 work. Instead the current time computation would always
114 be less then the trigger times. This had an adverse affect
115 on the client's ability to maintain communication with servers,
116 keep volumes up to date, and flush user tokens and acls
117 when they have expired. This was broken when the 1.3 branch
118 was modified to support VC7 which no longer included
121 * An initialization problem with the Freelance code was
122 detected while fixing the callbackRequest. The cm_rootSCachep
123 object is obtained during afsd_InitDaemons() but the callback
124 information is incomplete. The callback information will not
125 be obtained until cm_MergeStatus is called from within
126 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
127 test for the conditions under which the callback information
130 * Reports have been filed indicating that callbacks were
131 being lost. An examination of the code indicated that the
132 cm_server_t objects were not being properly reference
133 counted by the cm_scache_t and cm_callbackRequest_t objects.
134 In particular, the cm_server_t objects may have been freed
135 from beneath the cm_conn_t objects.
137 All of the reference counting is now done via the functions:
142 this improves the ability to track the referrals.
144 Each cm_BeginCallbackGranting Call now allocates a reference
145 to the cm_server_t. The cm_EndCallbackGrantingCall either
146 frees the reference or transfers it to the cm_scache_t
147 cbServerp field. These are then appropriately tracked
148 through the cm_Analyze call.
150 * Ensure that the dnlc hash table is the same size as the
151 dir name hash table (as per original author's note).
152 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
153 for compatibility with 64-bit systems.
155 * fix smb_ApplyV3DirListPatches to properly apply the hidden
156 attribute to dotfiles when the infoLevel < 0x101 and
157 cm_SyncOp has failed.
159 * Fix the Freelance registry initialization code. There
160 was a possibility that some systems could end up with
161 garbage in the registry during a clean install.
164 * file and directory names beginning with "." will now be given the
165 hidden attribute when the volume access is anonymous. this matches
166 the behavior when the volume access is via an authenticated user.
168 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
169 key. When a change occurs mark the root.afs data as invalid and
170 for it to be reloaded on the next access. This allows administrators
171 to modify the mount point list without restarting the service.
173 The freelance client used to provide a fake modification time for
174 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
175 Added code to extract the last modification time of the Freelance
176 registry key and use that instead. The time now represents the
177 most recent mount point change.
179 * PTS registration of new users to foreign cells has been added to
182 * Additional Cache Control and Credential Manager options have been
183 added to the WiX installer. See deployment guide for details.
185 * The CachePath setting is now optionally a REG_EXPAND_SZ type
187 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
190 * The loopback installation code may have had a problem updating the
191 %ETC%\HOSTS file which could have resulted in a premature failure.
192 Work around code has been added for the case where the file cannot
195 * The default max chunksize was increased from 15 (32K) to 17 (128K)
196 because Windows sends 64K blocks when using overlapped writes.
198 * The default number of server threads was increased from 4 to 25 to
199 better handle overlapped writes.
201 * The "AfscredsShortcutParams" registry value was not being properly
202 loaded by afscreds.exe. Therefore, the default value was always being
203 used instead of the value set by the installer.
205 * Windows XP provides downgrade attack detection to prevent an attacker
206 from being able to force the use of NTLM simply by disrupting
207 communication with the KDC. This attack cannot exist between the
208 Windows CIFS client and the AFS Client Service. Therefore, when a
209 downgrade has been detected the afs pioctl library will force the
210 establishment of a new CIFS connection using NTLM.
212 * A locking error was discovered surrounding all references to volume
213 server lists within the cm_cell.c source file.
215 * The logged into Windows username was incorrect on Terminal Server
218 * A new registry value "NonPersistentCaching" was added to the service
219 parameters key. When set to a non-zero value, the afs cache is stored
220 in the Windows paging file. There are two limitations to choosing
222 1. when persistent caching is implemented it won't work with
223 this flag set since there will be nothing to persist.
224 2. with this flag set the initial paging allocation cannot be
225 changed while the service is running
227 * An initialization bug was discovered in aklog.exe which affected users
228 who have a domain name for their afs servers which could not be mapped
232 * afs_config.exe now validates cell names against DNS in addition
233 to the CellServDB file.
235 * In order to allow the freelance client to connect to a volume with ID
236 equal to 1 on the default cell we changed the fake root.afs volume ID
237 once again. This time we choose 0xFFFFFFFF. In addition, we change
238 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
239 It will now be impossible for a volume ID to match that of another
240 cell unless the client is connected to 0xFFFFFFFD cells. That should
241 be enough room for growth.
243 * Fix "fs mkmount" command to work with UNC paths and when
244 started from non-AFS drives. It is now possible to create a mount
245 point in the freelance fake root.afs volume with the command
247 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
251 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
252 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
254 * The algorithm used to re-attempt access to the servers associated with
255 a volume has been altered to properly address the case in which all
256 servers have been marked down. The previous algorithm did not reset
257 the server's down flags so the servers were never actually retried.
258 This caused a problem with active volumes if the network connectivity
259 was lost as could be the case with a network cable removal, wireless
260 drop, or laptop hibernation. With the fix volume access is restored
261 almost instantenously when network connectivity becomes available.
263 * Support for SMB/CIFS browsing has been added to the AFS Client Service
264 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
265 listing of AFS submounts and freelance mount points. Support for
266 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
267 significantly enhances the behavior of AFS volumes within the Explorer
268 Shell. For instance, "AFS" now shows up as server in the Explorer
269 with each submount or freelance mount point visible as a share.
270 The right click menu in each folder now works with full functionality
271 on a consistent basis.
273 * The network provider can be configured to have different behavior
274 depending on the domain that the user logs into. These settings are
275 only relevant when using integrated login. A domain refers to an
276 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
277 local machine (i.e. local account logins). The domain name that is
278 used for selecting the domain would be the domain that is passed into
279 the NPLogonNotify function of the network provider. (see registry.txt
282 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
283 "Authentication Cell" which may be used to specify a default
284 authentication cell for afscreds.exe which is different from
285 the default cell for the AFS Client Service daemon.
287 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
288 afslogon.dll moved to %WINDIR%\System32\.
289 New registry entries added to register the dll for Winlogon events.
291 The logoff event will now force a call to ktc_ForgetAllTokens()
292 using the context of the user being logged off as long as the
293 user's profile is not loaded from within AFS. If the profile
294 was loaded from AFS we can't release the tokens since the Logoff
295 event is triggered prior to the profile being written back to
296 the its source location. This is now performed in an XP SP2
299 * Windows XP SP2 Internet Connection Firewall interoperability
302 * The %WINDIR%\afsdsbmt.ini contains four sections:
303 Submounts, Drive Mappings, Active Maps and CSC Policies.
304 The Submounts and CSC policies are now stored in the registry under
305 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
306 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
307 The Drive Mappings and Active Maps are stored in the registry under
308 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
309 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
311 There is no automatic migration of this data as it would be impossible
312 to consistently migrate data to user profiles which may not be active
313 when the machine is updated.
315 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
316 fake root.afs volume. For the same reasons as for the cellservdb file,
317 this information should not be in %WINDIR%. This information is now
318 kept under the registry key
319 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
321 The data from the afs_freelance.ini file will be automatically
322 migrated to the registry on first execution of afsd_service.exe
324 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
325 troublesome for several reasons. One, it is confusing for those who
326 expect the file to be named "CellServDB" instead of "afsdcell.ini".
327 Two, this file is not a Windows Profile formatted file. Three,
328 applications should not be reading or writing to %WINDIR%. It causes
329 problems for Windows Terminal Server.
331 The new location of CellServDB will be the OpenAFS Client install
332 directory which is by default C:\Program Files\OpenAFS\Client and can
333 be determined by querying the registry for
334 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
336 The existing afsdcell.ini will be migrated by the NSIS installer.
337 The Wix installer must still be updated to do the same.
339 * Change NSIS installer to use DNS by default; to remove Integrated Logon
340 High Security mode; and to add Terminal Services compatibility registry
341 entries to allow the OpenAFS tools to find the afsdcell.ini and other
342 configuration files in %WINDIR%.
344 * Add support for authenticated SMB connections. This will remove
345 the need for high security mode in most situations. Both NTLM
346 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
347 only NTLM can be used even though Kerberos is now supported. The
348 reason is that it is not possible to construct a service principal
349 which is unique to each individual machine.
351 SMB Extended Auth does not work on XP SP2 unless one of two registry
352 modifications are made:
354 (1) To disable the check for matching host names on loopback connections
355 set this key. This does not require a reboot:
357 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
358 "DisableLoopbackCheck"=dword:00000001
360 (2) To add the AFS SMB/CIFS service name to an approved list. This
361 does require a reboot:
363 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
364 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
366 afsd_service.exe will automatically add the current Netbios Name
367 to the BackConnectionHostNames list and then temporarily disable
368 the loopback check for one cycle of startup/shutdown of the service.
369 We assume most folks do not start/stop without a reboot so this
370 will be adequate in most cases.
372 * Fix security hole in afslogon.dll which allowed passwords to be
373 sent in clear text to the KDC in a misformed principal name.
375 * Fix cm_GetCell() to properly handle expired dns entries
378 * If Freelance mode is active and the afs_freelance.ini
379 file does not exist, do not create an empty file.
380 Instead create a file containing ro and rw mountpoints
381 to the default cell using the standard conventions.
383 * Modify the Freelance support to handle the ability
384 to create rw mount points in the fake root.afs volume.
386 * Changed the RPC mechanism used for token setting from
387 named pipes to local. Use of named pipes can be restored
388 by setting the environment variable AFS_RPC_PROTSEQ to
391 Named pipes were required when a Windows 9x system was
392 using a NT system in gateway mode which is incompatible
393 with our use of local loopback adapters.
395 * In afscreds.exe, if a username of the form user@REALM is
396 specified and no password is specified, do not perform a
397 kinit operation. Only perform the aklog functionality.
399 * Add a new registry value which allows the number of processors
400 on which afsd_service.exe executes to be restricted. Valid
401 values are 1..numOfProcessors
403 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
407 * A second MSI based installer option is now available.
409 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
410 request tickets for user/instance@REALM instead of just user@REALM
412 * Modify the Power Management Notify routine to wait for the Hard Dead
413 timeout period instead of a fixed 19 seconds. With the longer timeout
414 periods Hibernation and Standby could never succeed when network
415 connectivity is not available.
417 * The following fs.exe commands are now restricted to Administrator:
418 - checkservers with a non-zero timer value
421 - sysname with a new sysname list
430 setting the default sysname for a machine should be done via the
431 registry and not via "fs sysname".
433 * NSIS installer adds options to install Debugging Symbols
434 and the Microsoft Loopback Adapter; the user is now also
435 given the ability to select the afscreds.exe startup options.
437 * Build system modified to generate symbols for FREE (aka RELEASE)
438 builds as well as CHECKED (aka DEBUG) builds
440 * Sites which have a volume ID of 0x20000001 assigned to their
441 root.cell volumes have been experiencing problems with accessing
442 the root.cell volume of their cell when Freelance mode has been
443 active. This was because 0x20000001 was assigned to the fake
444 root.afs volume created by freelance. The fake volume id is
445 now set to 0x00000001 to prevent conflicts.
447 * The timeout logic in the AFS Client Service has been wrong
448 for sometime. It is based on two different assumptions.
449 First, the SMB client timeout is a fix value as was the case
450 with OS/2 Lan Manager. This assumption is incorrect. The
451 SMB timeout in Windows is a dynamic value computed based upon
452 a fixed minimum timeout to which is added time based upon the
453 size of the request and the performance characteristics of
454 the connection. Second, it is the responsibility of the
455 SMB Server to enforce the timeout requirements of the client.
456 This is untrue. The SMB Server cannot be expected to know
457 the requirements of the client. More importantly, if the
458 SMB server uses the SMB client timeout as a value to restrict
459 its behavior as an RX client, the performance characteristics
460 of the local SMB session would be used to prematurely terminate
461 WAN connections with significantly different performance
464 The timeout logic has therefore been modified in the following
466 . the Lan Manager Workstation (SMB) Session Timeout is used only
467 as a basis for configuring the Connection Dead Timeout
468 and Hard Dead Timeout values. The Connection Dead Timeout
469 must be at least 15 seconds longer than the SMB Timeout
470 and the Hard Dead Timeout must be at least double the
471 Connection Dead Timeout.
472 . New registry entries have been added to allow the Connection
473 Dead Timeout and Hard Dead Timeout values independent of the
474 Lan Manager Workstation Session Timeout
475 . The test to enforce the SMB Client Timeout has been removed.
477 One of the side-effects of removing the enforcement of the SMB
478 Client Timeout is that regardless of whether or not the SMB client
479 is available to receive the response (and how would the SMB server
480 know) the RX protocol response can be used to update the AFS
481 Client Service state for ready access by future SMB client
484 This should be the end of the "Server paused or restarting messages"
486 * Add support for arbitrary UNC paths to the pioctl() support.
487 This enables the fs commands as well as the AFS Shell Extension
488 to work correctly when UNC paths are being used.
490 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
491 DNS if the cell configuration cannot be determined via CellServDB
493 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
494 are ever set more than once at a time
496 * Fix the management of lists of cm_cell_t structures when using
497 DNS to lookup cell information. The previous code would fail to
498 reuse the same cellID for a cell if DNS was used more than once
499 for a given cell name. When the ttl expired, a single cm_cell_t
500 could be inserted into the cm_allCellsp list more than once
501 producing a loop. In addition, the vlServerp list belonging to
502 the cell was not freed resulting in improper refCounting of the
505 * Add DNS support to cm_IoctlNewCell() which previous only examined
508 * Add cm_FreeServer() function and call it from cm_FreeServerList()
509 to properly garbage collect cm_server_t objects
511 * Add numVCs variable to smb.c to track the number of smb_vc_t
512 objects created and use it to initialize the vcID field which
513 previously was set to 0 in all objects resulting in FindByID
516 * Fixed DNS lookups to work consistently throughout the OpenAFS
517 product instead of just from within the afsd_service.exe
519 * Added a runtime check to ensure that AFS Client Service SMB
520 Server is accepting connections before attempting to mount
523 * Read IP addresses for volume servers out of the CellServDB
524 file if gethostbyname() on the hostname fails.
526 * Fix getcellconfig() to populate both the Hostnames as well
527 as IP addresses when loading cell data via DNS
529 * Increase the Connection Dead Time to 50 from 20 seconds
530 Increase the Hard Dead Time to 120 from 40 seconds
531 (matches the Unix values)
533 * Fixed an assertion validating the number of allocated NCBs
535 * Fixed the build environment to consistently build for
536 Windows 2000 and above. (APPVER = 5.0)
538 * Fixed rx_debug to properly validate the receipt in incoming
539 data with select() and recvfrom(). Do not copy data out of
540 the socket buffer unless success is indicated.
543 * afsd_service.exe will now display a message box to the
544 desktop when it terminates due to an IP Address Change.
546 * installer no longer deletes AFS Server configuration data
549 * installer generates a warning dialog if the RPC service
550 is not properly configured
552 * installer compressed with lzma instead of bzip2
554 * afsd_service.exe shutdown crash solved once and for all
556 * reference counting of smb_vc_t data structures improved
558 * name space collision of smb_fid_t event objects corrected
560 * the output of "fs memdump" is now written to
561 %WINDIR%\TEMP\afsd_alloc.log
563 * the file TaAfsApp_1033.dll is now properly installed allowing
564 the User Manager to start
566 * a new algorithm is used for computing filename pattern matches
568 * afscreds.exe now accepts user names containing instance
571 * Fix the Directory Name Lookup Cache to be case-sensitive.
572 This is crucial in environments in which a Windows client
573 is accessing a directory with more than one filename that
574 differs only by case. If the directory contains "FOO"
575 and "Foo". You want "DEL Foo" to delete the correct one.
576 We still have a problem in that "DEL foo" will delete a
577 random filename. This will be addressed in a future release.
579 * Fix afscreds.exe -M option (renewMaps) to work when High
580 Security mode is off. Also, remember to disable the ActiveMap
581 flag in afsdsbmt.ini when a drive mapping is removed.
583 * Updates to NSIS installer script. AFS Server configuration
584 data will not be destroyed on un-install or re-install.
585 Use a better compression algorithm.
587 * afslogon.dll now uses KFW to obtain tokens when available
589 * afslogon.dll when given an all uppercase username will
590 attempt to authenticate with both the uppercase name
591 and an all lowercase variation
593 * DST modification removed. The fix appears to make things
594 worse after a reboot of the machine.
596 * fs.exe: added "cscpolicy" which is used to
597 change client side caching policy for AFS shares
599 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
600 [-documents] [-disable] [-help]
602 * Several uninitialized variables have been initialized
604 * It is now possible to obtain tokens using cross realm
605 Kerberos within afscreds.exe:
607 user: jaltman@ATHENA.MIT.EDU
609 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
610 will will in turn be used to obtain afs@DEMENTIA.ORG.
611 The resulting token will be stored with the display name
612 jaltman@ATHENA.MIT.EDU@dementia.org
614 * aklog.exe has been added to the client
616 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
617 [[-p | -path] pathname]
621 -d gives debugging information.
622 krb_realm is the kerberos realm of a cell.
623 pathname is the name of a directory to which you wish to authenticate.
624 -noprdb means don't try to determine AFS ID.
625 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
626 (default is Kerberos V)
627 No commandline arguments means authenticate to the local cell.
630 * All of the resource files have been restructured to adhere to
631 a set of rules IBM implemented for loading string resources.
632 These rules had either been forgotten or were not discovered
633 by folks working on the OpenAFS sources. The end result was
634 memory corruption. This is primary item which was preventing
635 the AFS Server from working.
637 * Increased the size of the maximum ticket size stored in a token
638 from 344 bytes to 12,000. Increased the buffers used to convey
639 messages between the pioctl() caller and the SMB Server from
640 1000 bytes to 12,512. The code appeared to have been writing
641 above the top of the stack by quite a few number of bytes.
642 (The increased ticket size is necessary for the next item.)
644 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
645 Instead the raw Kerberos 5 ticket is used in its entirety. This
646 is extremely important as it allows us to use pure Kerberos 5 KDCs
647 as the source of the AFS authentication. The use of up to 12,000 byte
648 tickets will allow tickets produced by all versions of Microsoft
649 Active Directory to be used.
650 - create a user account.
651 - designate it DES only
653 - specify its UPN to be "afs@realm"
654 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
656 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
657 is special when using long file names. (you must use "*.*" and not "*")
658 Instead only enforce it when performing 8dot3 searches.
660 * Fixed the DST problem with creation times being set one hour ahead
662 * Fixed the problem when using \\afs\cell-alias. For example,
663 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
664 for the alias name; instead simply expand the name. One of the
665 symptoms of this problem was a loss of acquired tokens.
667 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
668 of strings. (Only English strings provided.)
670 * Fixed the installer to properly replace in use files.
672 * Fixed the build system to cleanup generated component version files
674 * The release build compiled with MSVC 6.0 compiler to avoid the
675 afsd_service.exe shutdown crash. This does not solve the problem
676 but simply avoids it for the time being.
680 * fix afslogon.dll to not corrupt memory when High Security mode
683 * fix afsd_service.exe to not attempt to restore the stack when
684 an exception occurs. (not safe in multi-threaded programs)
686 * fix uninstaller to properly remove the CRT and MFC DLLs
688 * remove a Message Box from afscreds.exe when getcellconfig()
689 fails on a kerberos realm which is not a cell
691 The following is a list of changes to the OpenAFS for Window client
694 * "fs setserverprefs" will leave afsd service deadlocked
696 * "vos listaddrs" will core dump
698 * installer sets the appropriate keys to support Integrated Logon
700 * installer disables the "Find Lana by Name" functionality as it
701 was causing headaches for many users
703 * fix the intermittent crash of the power management thread when
704 shutting down the AFS Client Service
706 * optimizes the obtain drive mount list functionality which is
707 executed every time the mount tab in afscreds.exe and afs_config.exe
708 are refreshed. (this happens a lot)
710 * fix the service shutdown logic. add the STOP_PENDING state
711 and do not accept additional service events after we declare
714 The following is a list of changes to the OpenAFS for Window client
717 * flexelint was run against the source tree and hundreds (perhaps
718 thousands) of corrections were applied to ensure prototypes
719 were in use; types were used consistently; variables were
720 initialized; unused variables were removed; etc.
722 * A wide variety of instrumentation was added including the
723 ability to produce a stack trace from within afsd_service.exe
726 * Dynamic configuration of the RDRtimeout value based upon the
727 LanMan Workstation Session Timeout
729 * The mount root no longer needs to be called "/afs". This
730 is now set by a registry value "MountRoot" within the key
731 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
733 * The cell list is now only read out of afsdcell.ini when the
734 file changes instead of each time a cell is resolved.
736 * Thread synchronization was added to cm_server.c and ktc_nt.c
738 * All calls to GlobalAlloc()/GlobalFree() were replaced with
739 calloc()/free(). The Global functions were needed on Windows 3.x
740 but have caused a variety of problems on the Win32 platforms.
741 Avoiding them is highly recommended by several Microsoft
742 Knowledgebase articles
744 * Support for Symbolic Links added to the AFS Shell Extension
746 * Added a registry value "OverlayEnabled" to determine if
747 Shell Extension Overlays should be enabled.
748 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
750 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
751 separate trees for checked and free builds. Build system supports
752 a custom directory src\WINNT\extra which can be used as a grafting
753 location of organization specific additions to the build tree.
755 * New installer built using NSIS 2.0.
757 * Named all kernel objects in order to allow them to be monitored
758 with tools such as SysInternals' ProcExp.exe.
760 * Introduced new EventLog framework for AFSD
762 * Introduced Power Management interface to AFSD for Standby and
763 Hibernate modes to allow cache to be flushed prior to network
766 * Utilize Win32 DNSQuery API instead of internal routines. This
767 allows DNS SRV queries to be sent to all current domain name
768 servers. Not just one specified in an INI file. DNS is now
771 * "NetbiosName" registry value may be used to specify a fixed
772 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
773 when the loopback adapter is in use. If you need to use the
774 old notation with a loopback adapter installed specify a registry
777 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
779 * Refactor all modules which depend on LAN Adapter and NetbiosName
780 determination in a new library: lanahelper.lib. This allows for
781 consistent behavior throughout the product.
783 * Move the afsd.log and afsd_init.log files to the directory specified
784 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
785 for services. Added the Date to the log entries.
787 * New registry value "RxMaxMTU" used to limit the size of the RX
788 packets sent by the AFS Client Service to the Server. In order
789 to enable OpenAFS to work across the Cisco IPSec VPN the packet
790 size must be restricted to 1264 or smaller. The latest NSIS
791 installer sets a value of 1260 by default.
793 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
794 packets. This is not needed in order to work across the Cisco
795 VPN but might be needed for other network environments. This
796 value is not set by the NSIS installer.
798 * New registry value "HideDotFiles" is used to apply the Hidden
799 attribute to files whose names begin with a '.'. This value
800 is set by the NSIS installer.
802 * New registry value "MaxMpxRequests" allows the maximum number
803 of multiplexed sessions to be configured at run time. This
804 value is not set by the NSIS installer. The default value is
807 * New registry value "MaxVCPerServer" allows the maxmimum number
808 of VCs per server to be configured at run time. This value is
809 not set by the NSIS installer. The default value is 100.
811 * New registry value "AllSubmount" allows the "all" submount to
812 be disabled by setting its value to 0x00.
814 * Allow cells names to be valid mount points
815 \\<netbiosName>\<cellname>
817 * Store the active state of drive mappings in order for afscreds.exe
818 to restore them upon startup
820 * Add exception handling to generate a Stack Trace to the afsd_init.log
821 file if one happens to occur.
823 * Add lots of logging to help detect the cause of invalid SMB packets
825 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
826 conversion of Kerberos 5 "afs" service tickets. Supports auto-
827 renewal of expiring tokens as long as afscreds.exe is running.
829 * New afscreds.exe command line options:
831 -M = renew drive maps
832 -N = ip address change detection
835 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
836 determines whether or not MIT Kerberos for Windows should be used
837 to obtain tokens via Kerberos 5 tickets.
839 * New registry value "AfscredsShortcutParams" in
840 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
841 determines the command line parameters to be specified when "fixing"
842 the AFS Shortcut in the user's startup folder.
844 * The "ShowTrayIcon" registry value has been moved from
845 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
846 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
848 * The <cell name> registry values used to store the token expiration
849 reminders have been moved from
850 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
851 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
853 * Obtain the Logon User Name from the Explorer key when available
855 * new text document doc\txt\winnotes\registry.txt lists all registry
856 values used by OpenAFS (excluding the AFS Server)
858 * BUG: rx_securityClass objects were not properly reference
859 counted and were never freed.
861 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
862 would be generated. The existence of a server does not imply
863 that it is not down. If all of the servers for a cell are down
864 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
867 * BUG: the directory name lookup cache failed to free the entries
868 in the cache when the name cache entries cycled. The entries
869 in the cache would become dereferenced without being freed.
871 * BUG: fs setserverprefs could be executed without Administrator
874 * BUG: the number of allocated NCB objects (100) exceeded the number
875 which could actually be waited upon by the kernel (64). Any objects
876 which were utilized above the limit could never have event completions
879 * BUG: smb_username_t objects were not being reference counted and
880 were not properly freed.
882 * BUG: smb_tid_t objects could under unusual circumstances be freed
883 before they were no longer referenced.
885 * BUG: smb_fid_t object pointer were frequently used even when
886 their value could be NULL. They were not properly released and
887 therefore they were never freed.
889 * BUG: smb_packet_t data structures were not completely initialized
892 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
893 Denied" because that causes the Explorer Shell to try again until
894 access is obtained. Instead return "Remote Resources" which allows
895 the shell to move on and treat the error as transient.
897 * BUG: when initializing the NCBreturns structure, separate Event objects
898 were created for each NCB although a single Event object was supposed
901 * BUG: smb_dirSearch_t objects were not being properly referenced counted
904 * BUG: smb_tran2Packet_t objects were not being properly referenced
907 * BUG: directory path creation did not handle the case of multiple
908 directories requiring creation in one attempt
910 * BUG: SMB requests which required an Extended Response were ignored.
911 This prevented some files from being written to AFS volumes.
913 * BUG: character strings were being freed even after they were
914 inserted into in use data structures
916 * BUG: inconsistent usernames were used when High Security mode was
917 enabled. (there is still much to do in this area)
919 * BUG: pioctl() calls which require out of band RPC operations were
920 susceptible to race conditions when performed by multiple processes
922 * BUG: memory allocation and deallocation crossed instances of the
923 C Runtime Library producing memory leakage and corruption in
924 afscreds and the client configurator.
