2 * Fix the pattern matching algorithm to properly match patterns
5 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
6 which is used by both the original function and the new
7 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
8 creation of HardLinks in addition to Renaming. smb_Link()
9 is a new function which creates HardLinks via cm_Link().
10 cm_Link() is a new vnodeops function which creates links
13 smb_ReceiveNTRename() does not support the File Copy and
14 Move Cluster Information operations described in its interface.
15 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
17 * When opening files via symlinks, we should follow the symlinks
18 until we reach the actual file stat cache entry. The stat cache
19 entry of the file should then be stored in the FID instead of
20 stat scache entry of the symlink.
22 * return bad operation errors for all unimplemented functions
23 even if we do not know the functions exist.
25 * Log bad packets and unknown operation packets to the trace log
27 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
30 * Update list of known CIFS operations to include all those listed
31 in CIFS-TR-1p00_FINAL.pdf.
34 * A new Windows authorization group "AFS Client Admins" is now
35 created and populated with the members of the "Administrators"
36 group. The group is used to determine which accounts on the
37 machine may be used to modify the AFS Client Configuration via
38 the UI and command line tools. afs_config.exe, fs.exe,
40 * Modify the WinLogon Logoff Event Handler to query NT4 domain
41 controllers for the remote profile path if Active Directory
42 services are not available.
44 * Fix aklog.exe to not add the AFS ID to the username
46 * PTS registration of new users to foreign cells has been added to
49 * The cm_Daemon thread is used to perform checks for
50 down servers, up servers, volumes, callback expirations,
51 lock maintenance and token expiration. Due to a gaff in
52 larger integer division the thread never performed any
53 work. Instead the current time computation would always
54 be less then the trigger times. This had an adverse affect
55 on the client's ability to maintain communication with servers,
56 keep volumes up to date, and flush user tokens and acls
57 when they have expired. This was broken when the 1.3 branch
58 was modified to support VC7 which no longer included
61 * An initialization problem with the Freelance code was
62 detected while fixing the callbackRequest. The cm_rootSCachep
63 object is obtained during afsd_InitDaemons() but the callback
64 information is incomplete. The callback information will not
65 be obtained until cm_MergeStatus is called from within
66 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
67 test for the conditions under which the callback information
70 * Reports have been filed indicating that callbacks were
71 being lost. An examination of the code indicated that the
72 cm_server_t objects were not being properly reference
73 counted by the cm_scache_t and cm_callbackRequest_t objects.
74 In particular, the cm_server_t objects may have been freed
75 from beneath the cm_conn_t objects.
77 All of the reference counting is now done via the functions:
82 this improves the ability to track the referrals.
84 Each cm_BeginCallbackGranting Call now allocates a reference
85 to the cm_server_t. The cm_EndCallbackGrantingCall either
86 frees the reference or transfers it to the cm_scache_t
87 cbServerp field. These are then appropriately tracked
88 through the cm_Analyze call.
90 * Ensure that the dnlc hash table is the same size as the
91 dir name hash table (as per original author's note).
92 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
93 for compatibility with 64-bit systems.
95 * fix smb_ApplyV3DirListPatches to properly apply the hidden
96 attribute to dotfiles when the infoLevel < 0x101 and
99 * Fix the Freelance registry initialization code. There
100 was a possibility that some systems could end up with
101 garbage in the registry during a clean install.
104 * file and directory names beginning with "." will now be given the
105 hidden attribute when the volume access is anonymous. this matches
106 the behavior when the volume access is via an authenticated user.
108 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
109 key. When a change occurs mark the root.afs data as invalid and
110 for it to be reloaded on the next access. This allows administrators
111 to modify the mount point list without restarting the service.
113 The freelance client used to provide a fake modification time for
114 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
115 Added code to extract the last modification time of the Freelance
116 registry key and use that instead. The time now represents the
117 most recent mount point change.
119 * PTS registration of new users to foreign cells has been added to
122 * Additional Cache Control and Credential Manager options have been
123 added to the WiX installer. See deployment guide for details.
125 * The CachePath setting is now optionally a REG_EXPAND_SZ type
127 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
130 * The loopback installation code may have had a problem updating the
131 %ETC%\HOSTS file which could have resulted in a premature failure.
132 Work around code has been added for the case where the file cannot
135 * The default max chunksize was increased from 15 (32K) to 17 (128K)
136 because Windows sends 64K blocks when using overlapped writes.
138 * The default number of server threads was increased from 4 to 25 to
139 better handle overlapped writes.
141 * The "AfscredsShortcutParams" registry value was not being properly
142 loaded by afscreds.exe. Therefore, the default value was always being
143 used instead of the value set by the installer.
145 * Windows XP provides downgrade attack detection to prevent an attacker
146 from being able to force the use of NTLM simply by disrupting
147 communication with the KDC. This attack cannot exist between the
148 Windows CIFS client and the AFS Client Service. Therefore, when a
149 downgrade has been detected the afs pioctl library will force the
150 establishment of a new CIFS connection using NTLM.
152 * A locking error was discovered surrounding all references to volume
153 server lists within the cm_cell.c source file.
155 * The logged into Windows username was incorrect on Terminal Server
158 * A new registry value "NonPersistentCaching" was added to the service
159 parameters key. When set to a non-zero value, the afs cache is stored
160 in the Windows paging file. There are two limitations to choosing
162 1. when persistent caching is implemented it won't work with
163 this flag set since there will be nothing to persist.
164 2. with this flag set the initial paging allocation cannot be
165 changed while the service is running
167 * An initialization bug was discovered in aklog.exe which affected users
168 who have a domain name for their afs servers which could not be mapped
172 * afs_config.exe now validates cell names against DNS in addition
173 to the CellServDB file.
175 * In order to allow the freelance client to connect to a volume with ID
176 equal to 1 on the default cell we changed the fake root.afs volume ID
177 once again. This time we choose 0xFFFFFFFF. In addition, we change
178 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
179 It will now be impossible for a volume ID to match that of another
180 cell unless the client is connected to 0xFFFFFFFD cells. That should
181 be enough room for growth.
183 * Fix "fs mkmount" command to work with UNC paths and when
184 started from non-AFS drives. It is now possible to create a mount
185 point in the freelance fake root.afs volume with the command
187 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
191 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
192 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
194 * The algorithm used to re-attempt access to the servers associated with
195 a volume has been altered to properly address the case in which all
196 servers have been marked down. The previous algorithm did not reset
197 the server's down flags so the servers were never actually retried.
198 This caused a problem with active volumes if the network connectivity
199 was lost as could be the case with a network cable removal, wireless
200 drop, or laptop hibernation. With the fix volume access is restored
201 almost instantenously when network connectivity becomes available.
203 * Support for SMB/CIFS browsing has been added to the AFS Client Service
204 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
205 listing of AFS submounts and freelance mount points. Support for
206 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
207 significantly enhances the behavior of AFS volumes within the Explorer
208 Shell. For instance, "AFS" now shows up as server in the Explorer
209 with each submount or freelance mount point visible as a share.
210 The right click menu in each folder now works with full functionality
211 on a consistent basis.
213 * The network provider can be configured to have different behavior
214 depending on the domain that the user logs into. These settings are
215 only relevant when using integrated login. A domain refers to an
216 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
217 local machine (i.e. local account logins). The domain name that is
218 used for selecting the domain would be the domain that is passed into
219 the NPLogonNotify function of the network provider. (see registry.txt
222 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
223 "Authentication Cell" which may be used to specify a default
224 authentication cell for afscreds.exe which is different from
225 the default cell for the AFS Client Service daemon.
227 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
228 afslogon.dll moved to %WINDIR%\System32\.
229 New registry entries added to register the dll for Winlogon events.
231 The logoff event will now force a call to ktc_ForgetAllTokens()
232 using the context of the user being logged off as long as the
233 user's profile is not loaded from within AFS. If the profile
234 was loaded from AFS we can't release the tokens since the Logoff
235 event is triggered prior to the profile being written back to
236 the its source location. This is now performed in an XP SP2
239 * Windows XP SP2 Internet Connection Firewall interoperability
242 * The %WINDIR%\afsdsbmt.ini contains four sections:
243 Submounts, Drive Mappings, Active Maps and CSC Policies.
244 The Submounts and CSC policies are now stored in the registry under
245 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
246 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
247 The Drive Mappings and Active Maps are stored in the registry under
248 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
249 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
251 There is no automatic migration of this data as it would be impossible
252 to consistently migrate data to user profiles which may not be active
253 when the machine is updated.
255 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
256 fake root.afs volume. For the same reasons as for the cellservdb file,
257 this information should not be in %WINDIR%. This information is now
258 kept under the registry key
259 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
261 The data from the afs_freelance.ini file will be automatically
262 migrated to the registry on first execution of afsd_service.exe
264 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
265 troublesome for several reasons. One, it is confusing for those who
266 expect the file to be named "CellServDB" instead of "afsdcell.ini".
267 Two, this file is not a Windows Profile formatted file. Three,
268 applications should not be reading or writing to %WINDIR%. It causes
269 problems for Windows Terminal Server.
271 The new location of CellServDB will be the OpenAFS Client install
272 directory which is by default C:\Program Files\OpenAFS\Client and can
273 be determined by querying the registry for
274 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
276 The existing afsdcell.ini will be migrated by the NSIS installer.
277 The Wix installer must still be updated to do the same.
279 * Change NSIS installer to use DNS by default; to remove Integrated Logon
280 High Security mode; and to add Terminal Services compatibility registry
281 entries to allow the OpenAFS tools to find the afsdcell.ini and other
282 configuration files in %WINDIR%.
284 * Add support for authenticated SMB connections. This will remove
285 the need for high security mode in most situations. Both NTLM
286 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
287 only NTLM can be used even though Kerberos is now supported. The
288 reason is that it is not possible to construct a service principal
289 which is unique to each individual machine.
291 SMB Extended Auth does not work on XP SP2 unless one of two registry
292 modifications are made:
294 (1) To disable the check for matching host names on loopback connections
295 set this key. This does not require a reboot:
297 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
298 "DisableLoopbackCheck"=dword:00000001
300 (2) To add the AFS SMB/CIFS service name to an approved list. This
301 does require a reboot:
303 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
304 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
306 afsd_service.exe will automatically add the current Netbios Name
307 to the BackConnectionHostNames list and then temporarily disable
308 the loopback check for one cycle of startup/shutdown of the service.
309 We assume most folks do not start/stop without a reboot so this
310 will be adequate in most cases.
312 * Fix security hole in afslogon.dll which allowed passwords to be
313 sent in clear text to the KDC in a misformed principal name.
315 * Fix cm_GetCell() to properly handle expired dns entries
318 * If Freelance mode is active and the afs_freelance.ini
319 file does not exist, do not create an empty file.
320 Instead create a file containing ro and rw mountpoints
321 to the default cell using the standard conventions.
323 * Modify the Freelance support to handle the ability
324 to create rw mount points in the fake root.afs volume.
326 * Changed the RPC mechanism used for token setting from
327 named pipes to local. Use of named pipes can be restored
328 by setting the environment variable AFS_RPC_PROTSEQ to
331 Named pipes were required when a Windows 9x system was
332 using a NT system in gateway mode which is incompatible
333 with our use of local loopback adapters.
335 * In afscreds.exe, if a username of the form user@REALM is
336 specified and no password is specified, do not perform a
337 kinit operation. Only perform the aklog functionality.
339 * Add a new registry value which allows the number of processors
340 on which afsd_service.exe executes to be restricted. Valid
341 values are 1..numOfProcessors
343 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
347 * A second MSI based installer option is now available.
349 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
350 request tickets for user/instance@REALM instead of just user@REALM
352 * Modify the Power Management Notify routine to wait for the Hard Dead
353 timeout period instead of a fixed 19 seconds. With the longer timeout
354 periods Hibernation and Standby could never succeed when network
355 connectivity is not available.
357 * The following fs.exe commands are now restricted to Administrator:
358 - checkservers with a non-zero timer value
361 - sysname with a new sysname list
370 setting the default sysname for a machine should be done via the
371 registry and not via "fs sysname".
373 * NSIS installer adds options to install Debugging Symbols
374 and the Microsoft Loopback Adapter; the user is now also
375 given the ability to select the afscreds.exe startup options.
377 * Build system modified to generate symbols for FREE (aka RELEASE)
378 builds as well as CHECKED (aka DEBUG) builds
380 * Sites which have a volume ID of 0x20000001 assigned to their
381 root.cell volumes have been experiencing problems with accessing
382 the root.cell volume of their cell when Freelance mode has been
383 active. This was because 0x20000001 was assigned to the fake
384 root.afs volume created by freelance. The fake volume id is
385 now set to 0x00000001 to prevent conflicts.
387 * The timeout logic in the AFS Client Service has been wrong
388 for sometime. It is based on two different assumptions.
389 First, the SMB client timeout is a fix value as was the case
390 with OS/2 Lan Manager. This assumption is incorrect. The
391 SMB timeout in Windows is a dynamic value computed based upon
392 a fixed minimum timeout to which is added time based upon the
393 size of the request and the performance characteristics of
394 the connection. Second, it is the responsibility of the
395 SMB Server to enforce the timeout requirements of the client.
396 This is untrue. The SMB Server cannot be expected to know
397 the requirements of the client. More importantly, if the
398 SMB server uses the SMB client timeout as a value to restrict
399 its behavior as an RX client, the performance characteristics
400 of the local SMB session would be used to prematurely terminate
401 WAN connections with significantly different performance
404 The timeout logic has therefore been modified in the following
406 . the Lan Manager Workstation (SMB) Session Timeout is used only
407 as a basis for configuring the Connection Dead Timeout
408 and Hard Dead Timeout values. The Connection Dead Timeout
409 must be at least 15 seconds longer than the SMB Timeout
410 and the Hard Dead Timeout must be at least double the
411 Connection Dead Timeout.
412 . New registry entries have been added to allow the Connection
413 Dead Timeout and Hard Dead Timeout values independent of the
414 Lan Manager Workstation Session Timeout
415 . The test to enforce the SMB Client Timeout has been removed.
417 One of the side-effects of removing the enforcement of the SMB
418 Client Timeout is that regardless of whether or not the SMB client
419 is available to receive the response (and how would the SMB server
420 know) the RX protocol response can be used to update the AFS
421 Client Service state for ready access by future SMB client
424 This should be the end of the "Server paused or restarting messages"
426 * Add support for arbitrary UNC paths to the pioctl() support.
427 This enables the fs commands as well as the AFS Shell Extension
428 to work correctly when UNC paths are being used.
430 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
431 DNS if the cell configuration cannot be determined via CellServDB
433 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
434 are ever set more than once at a time
436 * Fix the management of lists of cm_cell_t structures when using
437 DNS to lookup cell information. The previous code would fail to
438 reuse the same cellID for a cell if DNS was used more than once
439 for a given cell name. When the ttl expired, a single cm_cell_t
440 could be inserted into the cm_allCellsp list more than once
441 producing a loop. In addition, the vlServerp list belonging to
442 the cell was not freed resulting in improper refCounting of the
445 * Add DNS support to cm_IoctlNewCell() which previous only examined
448 * Add cm_FreeServer() function and call it from cm_FreeServerList()
449 to properly garbage collect cm_server_t objects
451 * Add numVCs variable to smb.c to track the number of smb_vc_t
452 objects created and use it to initialize the vcID field which
453 previously was set to 0 in all objects resulting in FindByID
456 * Fixed DNS lookups to work consistently throughout the OpenAFS
457 product instead of just from within the afsd_service.exe
459 * Added a runtime check to ensure that AFS Client Service SMB
460 Server is accepting connections before attempting to mount
463 * Read IP addresses for volume servers out of the CellServDB
464 file if gethostbyname() on the hostname fails.
466 * Fix getcellconfig() to populate both the Hostnames as well
467 as IP addresses when loading cell data via DNS
469 * Increase the Connection Dead Time to 50 from 20 seconds
470 Increase the Hard Dead Time to 120 from 40 seconds
471 (matches the Unix values)
473 * Fixed an assertion validating the number of allocated NCBs
475 * Fixed the build environment to consistently build for
476 Windows 2000 and above. (APPVER = 5.0)
478 * Fixed rx_debug to properly validate the receipt in incoming
479 data with select() and recvfrom(). Do not copy data out of
480 the socket buffer unless success is indicated.
483 * afsd_service.exe will now display a message box to the
484 desktop when it terminates due to an IP Address Change.
486 * installer no longer deletes AFS Server configuration data
489 * installer generates a warning dialog if the RPC service
490 is not properly configured
492 * installer compressed with lzma instead of bzip2
494 * afsd_service.exe shutdown crash solved once and for all
496 * reference counting of smb_vc_t data structures improved
498 * name space collision of smb_fid_t event objects corrected
500 * the output of "fs memdump" is now written to
501 %WINDIR%\TEMP\afsd_alloc.log
503 * the file TaAfsApp_1033.dll is now properly installed allowing
504 the User Manager to start
506 * a new algorithm is used for computing filename pattern matches
508 * afscreds.exe now accepts user names containing instance
511 * Fix the Directory Name Lookup Cache to be case-sensitive.
512 This is crucial in environments in which a Windows client
513 is accessing a directory with more than one filename that
514 differs only by case. If the directory contains "FOO"
515 and "Foo". You want "DEL Foo" to delete the correct one.
516 We still have a problem in that "DEL foo" will delete a
517 random filename. This will be addressed in a future release.
519 * Fix afscreds.exe -M option (renewMaps) to work when High
520 Security mode is off. Also, remember to disable the ActiveMap
521 flag in afsdsbmt.ini when a drive mapping is removed.
523 * Updates to NSIS installer script. AFS Server configuration
524 data will not be destroyed on un-install or re-install.
525 Use a better compression algorithm.
527 * afslogon.dll now uses KFW to obtain tokens when available
529 * afslogon.dll when given an all uppercase username will
530 attempt to authenticate with both the uppercase name
531 and an all lowercase variation
533 * DST modification removed. The fix appears to make things
534 worse after a reboot of the machine.
536 * fs.exe: added "cscpolicy" which is used to
537 change client side caching policy for AFS shares
539 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
540 [-documents] [-disable] [-help]
542 * Several uninitialized variables have been initialized
544 * It is now possible to obtain tokens using cross realm
545 Kerberos within afscreds.exe:
547 user: jaltman@ATHENA.MIT.EDU
549 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
550 will will in turn be used to obtain afs@DEMENTIA.ORG.
551 The resulting token will be stored with the display name
552 jaltman@ATHENA.MIT.EDU@dementia.org
554 * aklog.exe has been added to the client
556 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
557 [[-p | -path] pathname]
561 -d gives debugging information.
562 krb_realm is the kerberos realm of a cell.
563 pathname is the name of a directory to which you wish to authenticate.
564 -noprdb means don't try to determine AFS ID.
565 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
566 (default is Kerberos V)
567 No commandline arguments means authenticate to the local cell.
570 * All of the resource files have been restructured to adhere to
571 a set of rules IBM implemented for loading string resources.
572 These rules had either been forgotten or were not discovered
573 by folks working on the OpenAFS sources. The end result was
574 memory corruption. This is primary item which was preventing
575 the AFS Server from working.
577 * Increased the size of the maximum ticket size stored in a token
578 from 344 bytes to 12,000. Increased the buffers used to convey
579 messages between the pioctl() caller and the SMB Server from
580 1000 bytes to 12,512. The code appeared to have been writing
581 above the top of the stack by quite a few number of bytes.
582 (The increased ticket size is necessary for the next item.)
584 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
585 Instead the raw Kerberos 5 ticket is used in its entirety. This
586 is extremely important as it allows us to use pure Kerberos 5 KDCs
587 as the source of the AFS authentication. The use of up to 12,000 byte
588 tickets will allow tickets produced by all versions of Microsoft
589 Active Directory to be used.
590 - create a user account.
591 - designate it DES only
593 - specify its UPN to be "afs@realm"
594 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
596 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
597 is special when using long file names. (you must use "*.*" and not "*")
598 Instead only enforce it when performing 8dot3 searches.
600 * Fixed the DST problem with creation times being set one hour ahead
602 * Fixed the problem when using \\afs\cell-alias. For example,
603 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
604 for the alias name; instead simply expand the name. One of the
605 symptoms of this problem was a loss of acquired tokens.
607 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
608 of strings. (Only English strings provided.)
610 * Fixed the installer to properly replace in use files.
612 * Fixed the build system to cleanup generated component version files
614 * The release build compiled with MSVC 6.0 compiler to avoid the
615 afsd_service.exe shutdown crash. This does not solve the problem
616 but simply avoids it for the time being.
620 * fix afslogon.dll to not corrupt memory when High Security mode
623 * fix afsd_service.exe to not attempt to restore the stack when
624 an exception occurs. (not safe in multi-threaded programs)
626 * fix uninstaller to properly remove the CRT and MFC DLLs
628 * remove a Message Box from afscreds.exe when getcellconfig()
629 fails on a kerberos realm which is not a cell
631 The following is a list of changes to the OpenAFS for Window client
634 * "fs setserverprefs" will leave afsd service deadlocked
636 * "vos listaddrs" will core dump
638 * installer sets the appropriate keys to support Integrated Logon
640 * installer disables the "Find Lana by Name" functionality as it
641 was causing headaches for many users
643 * fix the intermittent crash of the power management thread when
644 shutting down the AFS Client Service
646 * optimizes the obtain drive mount list functionality which is
647 executed every time the mount tab in afscreds.exe and afs_config.exe
648 are refreshed. (this happens a lot)
650 * fix the service shutdown logic. add the STOP_PENDING state
651 and do not accept additional service events after we declare
654 The following is a list of changes to the OpenAFS for Window client
657 * flexelint was run against the source tree and hundreds (perhaps
658 thousands) of corrections were applied to ensure prototypes
659 were in use; types were used consistently; variables were
660 initialized; unused variables were removed; etc.
662 * A wide variety of instrumentation was added including the
663 ability to produce a stack trace from within afsd_service.exe
666 * Dynamic configuration of the RDRtimeout value based upon the
667 LanMan Workstation Session Timeout
669 * The mount root no longer needs to be called "/afs". This
670 is now set by a registry value "MountRoot" within the key
671 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
673 * The cell list is now only read out of afsdcell.ini when the
674 file changes instead of each time a cell is resolved.
676 * Thread synchronization was added to cm_server.c and ktc_nt.c
678 * All calls to GlobalAlloc()/GlobalFree() were replaced with
679 calloc()/free(). The Global functions were needed on Windows 3.x
680 but have caused a variety of problems on the Win32 platforms.
681 Avoiding them is highly recommended by several Microsoft
682 Knowledgebase articles
684 * Support for Symbolic Links added to the AFS Shell Extension
686 * Added a registry value "OverlayEnabled" to determine if
687 Shell Extension Overlays should be enabled.
688 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
690 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
691 separate trees for checked and free builds. Build system supports
692 a custom directory src\WINNT\extra which can be used as a grafting
693 location of organization specific additions to the build tree.
695 * New installer built using NSIS 2.0.
697 * Named all kernel objects in order to allow them to be monitored
698 with tools such as SysInternals' ProcExp.exe.
700 * Introduced new EventLog framework for AFSD
702 * Introduced Power Management interface to AFSD for Standby and
703 Hibernate modes to allow cache to be flushed prior to network
706 * Utilize Win32 DNSQuery API instead of internal routines. This
707 allows DNS SRV queries to be sent to all current domain name
708 servers. Not just one specified in an INI file. DNS is now
711 * "NetbiosName" registry value may be used to specify a fixed
712 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
713 when the loopback adapter is in use. If you need to use the
714 old notation with a loopback adapter installed specify a registry
717 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
719 * Refactor all modules which depend on LAN Adapter and NetbiosName
720 determination in a new library: lanahelper.lib. This allows for
721 consistent behavior throughout the product.
723 * Move the afsd.log and afsd_init.log files to the directory specified
724 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
725 for services. Added the Date to the log entries.
727 * New registry value "RxMaxMTU" used to limit the size of the RX
728 packets sent by the AFS Client Service to the Server. In order
729 to enable OpenAFS to work across the Cisco IPSec VPN the packet
730 size must be restricted to 1264 or smaller. The latest NSIS
731 installer sets a value of 1260 by default.
733 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
734 packets. This is not needed in order to work across the Cisco
735 VPN but might be needed for other network environments. This
736 value is not set by the NSIS installer.
738 * New registry value "HideDotFiles" is used to apply the Hidden
739 attribute to files whose names begin with a '.'. This value
740 is set by the NSIS installer.
742 * New registry value "MaxMpxRequests" allows the maximum number
743 of multiplexed sessions to be configured at run time. This
744 value is not set by the NSIS installer. The default value is
747 * New registry value "MaxVCPerServer" allows the maxmimum number
748 of VCs per server to be configured at run time. This value is
749 not set by the NSIS installer. The default value is 100.
751 * New registry value "AllSubmount" allows the "all" submount to
752 be disabled by setting its value to 0x00.
754 * Allow cells names to be valid mount points
755 \\<netbiosName>\<cellname>
757 * Store the active state of drive mappings in order for afscreds.exe
758 to restore them upon startup
760 * Add exception handling to generate a Stack Trace to the afsd_init.log
761 file if one happens to occur.
763 * Add lots of logging to help detect the cause of invalid SMB packets
765 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
766 conversion of Kerberos 5 "afs" service tickets. Supports auto-
767 renewal of expiring tokens as long as afscreds.exe is running.
769 * New afscreds.exe command line options:
771 -M = renew drive maps
772 -N = ip address change detection
775 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
776 determines whether or not MIT Kerberos for Windows should be used
777 to obtain tokens via Kerberos 5 tickets.
779 * New registry value "AfscredsShortcutParams" in
780 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
781 determines the command line parameters to be specified when "fixing"
782 the AFS Shortcut in the user's startup folder.
784 * The "ShowTrayIcon" registry value has been moved from
785 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
786 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
788 * The <cell name> registry values used to store the token expiration
789 reminders have been moved from
790 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
791 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
793 * Obtain the Logon User Name from the Explorer key when available
795 * new text document doc\txt\winnotes\registry.txt lists all registry
796 values used by OpenAFS (excluding the AFS Server)
798 * BUG: rx_securityClass objects were not properly reference
799 counted and were never freed.
801 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
802 would be generated. The existence of a server does not imply
803 that it is not down. If all of the servers for a cell are down
804 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
807 * BUG: the directory name lookup cache failed to free the entries
808 in the cache when the name cache entries cycled. The entries
809 in the cache would become dereferenced without being freed.
811 * BUG: fs setserverprefs could be executed without Administrator
814 * BUG: the number of allocated NCB objects (100) exceeded the number
815 which could actually be waited upon by the kernel (64). Any objects
816 which were utilized above the limit could never have event completions
819 * BUG: smb_username_t objects were not being reference counted and
820 were not properly freed.
822 * BUG: smb_tid_t objects could under unusual circumstances be freed
823 before they were no longer referenced.
825 * BUG: smb_fid_t object pointer were frequently used even when
826 their value could be NULL. They were not properly released and
827 therefore they were never freed.
829 * BUG: smb_packet_t data structures were not completely initialized
832 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
833 Denied" because that causes the Explorer Shell to try again until
834 access is obtained. Instead return "Remote Resources" which allows
835 the shell to move on and treat the error as transient.
837 * BUG: when initializing the NCBreturns structure, separate Event objects
838 were created for each NCB although a single Event object was supposed
841 * BUG: smb_dirSearch_t objects were not being properly referenced counted
844 * BUG: smb_tran2Packet_t objects were not being properly referenced
847 * BUG: directory path creation did not handle the case of multiple
848 directories requiring creation in one attempt
850 * BUG: SMB requests which required an Extended Response were ignored.
851 This prevented some files from being written to AFS volumes.
853 * BUG: character strings were being freed even after they were
854 inserted into in use data structures
856 * BUG: inconsistent usernames were used when High Security mode was
857 enabled. (there is still much to do in this area)
859 * BUG: pioctl() calls which require out of band RPC operations were
860 susceptible to race conditions when performed by multiple processes
862 * BUG: memory allocation and deallocation crossed instances of the
863 C Runtime Library producing memory leakage and corruption in
864 afscreds and the client configurator.
