2 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
3 "EnableKFW". This value will not be read if the key
4 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
5 value under that key does not.
7 * provide mechanisms to force the use of krb524d for Kerberos 5
8 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
9 there is a new registry value "Use524" and for aklog.exe a new
10 command line parameter "-m".
12 * Fix the pattern matching algorithm to properly match patterns
15 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
16 which is used by both the original function and the new
17 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
18 creation of HardLinks in addition to Renaming. smb_Link()
19 is a new function which creates HardLinks via cm_Link().
20 cm_Link() is a new vnodeops function which creates links
23 smb_ReceiveNTRename() does not support the File Copy and
24 Move Cluster Information operations described in its interface.
25 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
27 * When opening files via symlinks, we should follow the symlinks
28 until we reach the actual file stat cache entry. The stat cache
29 entry of the file should then be stored in the FID instead of
30 stat scache entry of the symlink.
32 * return bad operation errors for all unimplemented functions
33 even if we do not know the functions exist.
35 * Log bad packets and unknown operation packets to the trace log
37 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
40 * Update list of known CIFS operations to include all those listed
41 in CIFS-TR-1p00_FINAL.pdf.
44 * A new Windows authorization group "AFS Client Admins" is now
45 created and populated with the members of the "Administrators"
46 group. The group is used to determine which accounts on the
47 machine may be used to modify the AFS Client Configuration via
48 the UI and command line tools. afs_config.exe, fs.exe,
50 * Modify the WinLogon Logoff Event Handler to query NT4 domain
51 controllers for the remote profile path if Active Directory
52 services are not available.
54 * Fix aklog.exe to not add the AFS ID to the username
56 * PTS registration of new users to foreign cells has been added to
59 * The cm_Daemon thread is used to perform checks for
60 down servers, up servers, volumes, callback expirations,
61 lock maintenance and token expiration. Due to a gaff in
62 larger integer division the thread never performed any
63 work. Instead the current time computation would always
64 be less then the trigger times. This had an adverse affect
65 on the client's ability to maintain communication with servers,
66 keep volumes up to date, and flush user tokens and acls
67 when they have expired. This was broken when the 1.3 branch
68 was modified to support VC7 which no longer included
71 * An initialization problem with the Freelance code was
72 detected while fixing the callbackRequest. The cm_rootSCachep
73 object is obtained during afsd_InitDaemons() but the callback
74 information is incomplete. The callback information will not
75 be obtained until cm_MergeStatus is called from within
76 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
77 test for the conditions under which the callback information
80 * Reports have been filed indicating that callbacks were
81 being lost. An examination of the code indicated that the
82 cm_server_t objects were not being properly reference
83 counted by the cm_scache_t and cm_callbackRequest_t objects.
84 In particular, the cm_server_t objects may have been freed
85 from beneath the cm_conn_t objects.
87 All of the reference counting is now done via the functions:
92 this improves the ability to track the referrals.
94 Each cm_BeginCallbackGranting Call now allocates a reference
95 to the cm_server_t. The cm_EndCallbackGrantingCall either
96 frees the reference or transfers it to the cm_scache_t
97 cbServerp field. These are then appropriately tracked
98 through the cm_Analyze call.
100 * Ensure that the dnlc hash table is the same size as the
101 dir name hash table (as per original author's note).
102 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
103 for compatibility with 64-bit systems.
105 * fix smb_ApplyV3DirListPatches to properly apply the hidden
106 attribute to dotfiles when the infoLevel < 0x101 and
107 cm_SyncOp has failed.
109 * Fix the Freelance registry initialization code. There
110 was a possibility that some systems could end up with
111 garbage in the registry during a clean install.
114 * file and directory names beginning with "." will now be given the
115 hidden attribute when the volume access is anonymous. this matches
116 the behavior when the volume access is via an authenticated user.
118 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
119 key. When a change occurs mark the root.afs data as invalid and
120 for it to be reloaded on the next access. This allows administrators
121 to modify the mount point list without restarting the service.
123 The freelance client used to provide a fake modification time for
124 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
125 Added code to extract the last modification time of the Freelance
126 registry key and use that instead. The time now represents the
127 most recent mount point change.
129 * PTS registration of new users to foreign cells has been added to
132 * Additional Cache Control and Credential Manager options have been
133 added to the WiX installer. See deployment guide for details.
135 * The CachePath setting is now optionally a REG_EXPAND_SZ type
137 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
140 * The loopback installation code may have had a problem updating the
141 %ETC%\HOSTS file which could have resulted in a premature failure.
142 Work around code has been added for the case where the file cannot
145 * The default max chunksize was increased from 15 (32K) to 17 (128K)
146 because Windows sends 64K blocks when using overlapped writes.
148 * The default number of server threads was increased from 4 to 25 to
149 better handle overlapped writes.
151 * The "AfscredsShortcutParams" registry value was not being properly
152 loaded by afscreds.exe. Therefore, the default value was always being
153 used instead of the value set by the installer.
155 * Windows XP provides downgrade attack detection to prevent an attacker
156 from being able to force the use of NTLM simply by disrupting
157 communication with the KDC. This attack cannot exist between the
158 Windows CIFS client and the AFS Client Service. Therefore, when a
159 downgrade has been detected the afs pioctl library will force the
160 establishment of a new CIFS connection using NTLM.
162 * A locking error was discovered surrounding all references to volume
163 server lists within the cm_cell.c source file.
165 * The logged into Windows username was incorrect on Terminal Server
168 * A new registry value "NonPersistentCaching" was added to the service
169 parameters key. When set to a non-zero value, the afs cache is stored
170 in the Windows paging file. There are two limitations to choosing
172 1. when persistent caching is implemented it won't work with
173 this flag set since there will be nothing to persist.
174 2. with this flag set the initial paging allocation cannot be
175 changed while the service is running
177 * An initialization bug was discovered in aklog.exe which affected users
178 who have a domain name for their afs servers which could not be mapped
182 * afs_config.exe now validates cell names against DNS in addition
183 to the CellServDB file.
185 * In order to allow the freelance client to connect to a volume with ID
186 equal to 1 on the default cell we changed the fake root.afs volume ID
187 once again. This time we choose 0xFFFFFFFF. In addition, we change
188 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
189 It will now be impossible for a volume ID to match that of another
190 cell unless the client is connected to 0xFFFFFFFD cells. That should
191 be enough room for growth.
193 * Fix "fs mkmount" command to work with UNC paths and when
194 started from non-AFS drives. It is now possible to create a mount
195 point in the freelance fake root.afs volume with the command
197 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
201 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
202 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
204 * The algorithm used to re-attempt access to the servers associated with
205 a volume has been altered to properly address the case in which all
206 servers have been marked down. The previous algorithm did not reset
207 the server's down flags so the servers were never actually retried.
208 This caused a problem with active volumes if the network connectivity
209 was lost as could be the case with a network cable removal, wireless
210 drop, or laptop hibernation. With the fix volume access is restored
211 almost instantenously when network connectivity becomes available.
213 * Support for SMB/CIFS browsing has been added to the AFS Client Service
214 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
215 listing of AFS submounts and freelance mount points. Support for
216 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
217 significantly enhances the behavior of AFS volumes within the Explorer
218 Shell. For instance, "AFS" now shows up as server in the Explorer
219 with each submount or freelance mount point visible as a share.
220 The right click menu in each folder now works with full functionality
221 on a consistent basis.
223 * The network provider can be configured to have different behavior
224 depending on the domain that the user logs into. These settings are
225 only relevant when using integrated login. A domain refers to an
226 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
227 local machine (i.e. local account logins). The domain name that is
228 used for selecting the domain would be the domain that is passed into
229 the NPLogonNotify function of the network provider. (see registry.txt
232 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
233 "Authentication Cell" which may be used to specify a default
234 authentication cell for afscreds.exe which is different from
235 the default cell for the AFS Client Service daemon.
237 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
238 afslogon.dll moved to %WINDIR%\System32\.
239 New registry entries added to register the dll for Winlogon events.
241 The logoff event will now force a call to ktc_ForgetAllTokens()
242 using the context of the user being logged off as long as the
243 user's profile is not loaded from within AFS. If the profile
244 was loaded from AFS we can't release the tokens since the Logoff
245 event is triggered prior to the profile being written back to
246 the its source location. This is now performed in an XP SP2
249 * Windows XP SP2 Internet Connection Firewall interoperability
252 * The %WINDIR%\afsdsbmt.ini contains four sections:
253 Submounts, Drive Mappings, Active Maps and CSC Policies.
254 The Submounts and CSC policies are now stored in the registry under
255 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
256 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
257 The Drive Mappings and Active Maps are stored in the registry under
258 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
259 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
261 There is no automatic migration of this data as it would be impossible
262 to consistently migrate data to user profiles which may not be active
263 when the machine is updated.
265 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
266 fake root.afs volume. For the same reasons as for the cellservdb file,
267 this information should not be in %WINDIR%. This information is now
268 kept under the registry key
269 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
271 The data from the afs_freelance.ini file will be automatically
272 migrated to the registry on first execution of afsd_service.exe
274 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
275 troublesome for several reasons. One, it is confusing for those who
276 expect the file to be named "CellServDB" instead of "afsdcell.ini".
277 Two, this file is not a Windows Profile formatted file. Three,
278 applications should not be reading or writing to %WINDIR%. It causes
279 problems for Windows Terminal Server.
281 The new location of CellServDB will be the OpenAFS Client install
282 directory which is by default C:\Program Files\OpenAFS\Client and can
283 be determined by querying the registry for
284 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
286 The existing afsdcell.ini will be migrated by the NSIS installer.
287 The Wix installer must still be updated to do the same.
289 * Change NSIS installer to use DNS by default; to remove Integrated Logon
290 High Security mode; and to add Terminal Services compatibility registry
291 entries to allow the OpenAFS tools to find the afsdcell.ini and other
292 configuration files in %WINDIR%.
294 * Add support for authenticated SMB connections. This will remove
295 the need for high security mode in most situations. Both NTLM
296 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
297 only NTLM can be used even though Kerberos is now supported. The
298 reason is that it is not possible to construct a service principal
299 which is unique to each individual machine.
301 SMB Extended Auth does not work on XP SP2 unless one of two registry
302 modifications are made:
304 (1) To disable the check for matching host names on loopback connections
305 set this key. This does not require a reboot:
307 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
308 "DisableLoopbackCheck"=dword:00000001
310 (2) To add the AFS SMB/CIFS service name to an approved list. This
311 does require a reboot:
313 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
314 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
316 afsd_service.exe will automatically add the current Netbios Name
317 to the BackConnectionHostNames list and then temporarily disable
318 the loopback check for one cycle of startup/shutdown of the service.
319 We assume most folks do not start/stop without a reboot so this
320 will be adequate in most cases.
322 * Fix security hole in afslogon.dll which allowed passwords to be
323 sent in clear text to the KDC in a misformed principal name.
325 * Fix cm_GetCell() to properly handle expired dns entries
328 * If Freelance mode is active and the afs_freelance.ini
329 file does not exist, do not create an empty file.
330 Instead create a file containing ro and rw mountpoints
331 to the default cell using the standard conventions.
333 * Modify the Freelance support to handle the ability
334 to create rw mount points in the fake root.afs volume.
336 * Changed the RPC mechanism used for token setting from
337 named pipes to local. Use of named pipes can be restored
338 by setting the environment variable AFS_RPC_PROTSEQ to
341 Named pipes were required when a Windows 9x system was
342 using a NT system in gateway mode which is incompatible
343 with our use of local loopback adapters.
345 * In afscreds.exe, if a username of the form user@REALM is
346 specified and no password is specified, do not perform a
347 kinit operation. Only perform the aklog functionality.
349 * Add a new registry value which allows the number of processors
350 on which afsd_service.exe executes to be restricted. Valid
351 values are 1..numOfProcessors
353 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
357 * A second MSI based installer option is now available.
359 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
360 request tickets for user/instance@REALM instead of just user@REALM
362 * Modify the Power Management Notify routine to wait for the Hard Dead
363 timeout period instead of a fixed 19 seconds. With the longer timeout
364 periods Hibernation and Standby could never succeed when network
365 connectivity is not available.
367 * The following fs.exe commands are now restricted to Administrator:
368 - checkservers with a non-zero timer value
371 - sysname with a new sysname list
380 setting the default sysname for a machine should be done via the
381 registry and not via "fs sysname".
383 * NSIS installer adds options to install Debugging Symbols
384 and the Microsoft Loopback Adapter; the user is now also
385 given the ability to select the afscreds.exe startup options.
387 * Build system modified to generate symbols for FREE (aka RELEASE)
388 builds as well as CHECKED (aka DEBUG) builds
390 * Sites which have a volume ID of 0x20000001 assigned to their
391 root.cell volumes have been experiencing problems with accessing
392 the root.cell volume of their cell when Freelance mode has been
393 active. This was because 0x20000001 was assigned to the fake
394 root.afs volume created by freelance. The fake volume id is
395 now set to 0x00000001 to prevent conflicts.
397 * The timeout logic in the AFS Client Service has been wrong
398 for sometime. It is based on two different assumptions.
399 First, the SMB client timeout is a fix value as was the case
400 with OS/2 Lan Manager. This assumption is incorrect. The
401 SMB timeout in Windows is a dynamic value computed based upon
402 a fixed minimum timeout to which is added time based upon the
403 size of the request and the performance characteristics of
404 the connection. Second, it is the responsibility of the
405 SMB Server to enforce the timeout requirements of the client.
406 This is untrue. The SMB Server cannot be expected to know
407 the requirements of the client. More importantly, if the
408 SMB server uses the SMB client timeout as a value to restrict
409 its behavior as an RX client, the performance characteristics
410 of the local SMB session would be used to prematurely terminate
411 WAN connections with significantly different performance
414 The timeout logic has therefore been modified in the following
416 . the Lan Manager Workstation (SMB) Session Timeout is used only
417 as a basis for configuring the Connection Dead Timeout
418 and Hard Dead Timeout values. The Connection Dead Timeout
419 must be at least 15 seconds longer than the SMB Timeout
420 and the Hard Dead Timeout must be at least double the
421 Connection Dead Timeout.
422 . New registry entries have been added to allow the Connection
423 Dead Timeout and Hard Dead Timeout values independent of the
424 Lan Manager Workstation Session Timeout
425 . The test to enforce the SMB Client Timeout has been removed.
427 One of the side-effects of removing the enforcement of the SMB
428 Client Timeout is that regardless of whether or not the SMB client
429 is available to receive the response (and how would the SMB server
430 know) the RX protocol response can be used to update the AFS
431 Client Service state for ready access by future SMB client
434 This should be the end of the "Server paused or restarting messages"
436 * Add support for arbitrary UNC paths to the pioctl() support.
437 This enables the fs commands as well as the AFS Shell Extension
438 to work correctly when UNC paths are being used.
440 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
441 DNS if the cell configuration cannot be determined via CellServDB
443 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
444 are ever set more than once at a time
446 * Fix the management of lists of cm_cell_t structures when using
447 DNS to lookup cell information. The previous code would fail to
448 reuse the same cellID for a cell if DNS was used more than once
449 for a given cell name. When the ttl expired, a single cm_cell_t
450 could be inserted into the cm_allCellsp list more than once
451 producing a loop. In addition, the vlServerp list belonging to
452 the cell was not freed resulting in improper refCounting of the
455 * Add DNS support to cm_IoctlNewCell() which previous only examined
458 * Add cm_FreeServer() function and call it from cm_FreeServerList()
459 to properly garbage collect cm_server_t objects
461 * Add numVCs variable to smb.c to track the number of smb_vc_t
462 objects created and use it to initialize the vcID field which
463 previously was set to 0 in all objects resulting in FindByID
466 * Fixed DNS lookups to work consistently throughout the OpenAFS
467 product instead of just from within the afsd_service.exe
469 * Added a runtime check to ensure that AFS Client Service SMB
470 Server is accepting connections before attempting to mount
473 * Read IP addresses for volume servers out of the CellServDB
474 file if gethostbyname() on the hostname fails.
476 * Fix getcellconfig() to populate both the Hostnames as well
477 as IP addresses when loading cell data via DNS
479 * Increase the Connection Dead Time to 50 from 20 seconds
480 Increase the Hard Dead Time to 120 from 40 seconds
481 (matches the Unix values)
483 * Fixed an assertion validating the number of allocated NCBs
485 * Fixed the build environment to consistently build for
486 Windows 2000 and above. (APPVER = 5.0)
488 * Fixed rx_debug to properly validate the receipt in incoming
489 data with select() and recvfrom(). Do not copy data out of
490 the socket buffer unless success is indicated.
493 * afsd_service.exe will now display a message box to the
494 desktop when it terminates due to an IP Address Change.
496 * installer no longer deletes AFS Server configuration data
499 * installer generates a warning dialog if the RPC service
500 is not properly configured
502 * installer compressed with lzma instead of bzip2
504 * afsd_service.exe shutdown crash solved once and for all
506 * reference counting of smb_vc_t data structures improved
508 * name space collision of smb_fid_t event objects corrected
510 * the output of "fs memdump" is now written to
511 %WINDIR%\TEMP\afsd_alloc.log
513 * the file TaAfsApp_1033.dll is now properly installed allowing
514 the User Manager to start
516 * a new algorithm is used for computing filename pattern matches
518 * afscreds.exe now accepts user names containing instance
521 * Fix the Directory Name Lookup Cache to be case-sensitive.
522 This is crucial in environments in which a Windows client
523 is accessing a directory with more than one filename that
524 differs only by case. If the directory contains "FOO"
525 and "Foo". You want "DEL Foo" to delete the correct one.
526 We still have a problem in that "DEL foo" will delete a
527 random filename. This will be addressed in a future release.
529 * Fix afscreds.exe -M option (renewMaps) to work when High
530 Security mode is off. Also, remember to disable the ActiveMap
531 flag in afsdsbmt.ini when a drive mapping is removed.
533 * Updates to NSIS installer script. AFS Server configuration
534 data will not be destroyed on un-install or re-install.
535 Use a better compression algorithm.
537 * afslogon.dll now uses KFW to obtain tokens when available
539 * afslogon.dll when given an all uppercase username will
540 attempt to authenticate with both the uppercase name
541 and an all lowercase variation
543 * DST modification removed. The fix appears to make things
544 worse after a reboot of the machine.
546 * fs.exe: added "cscpolicy" which is used to
547 change client side caching policy for AFS shares
549 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
550 [-documents] [-disable] [-help]
552 * Several uninitialized variables have been initialized
554 * It is now possible to obtain tokens using cross realm
555 Kerberos within afscreds.exe:
557 user: jaltman@ATHENA.MIT.EDU
559 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
560 will will in turn be used to obtain afs@DEMENTIA.ORG.
561 The resulting token will be stored with the display name
562 jaltman@ATHENA.MIT.EDU@dementia.org
564 * aklog.exe has been added to the client
566 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
567 [[-p | -path] pathname]
571 -d gives debugging information.
572 krb_realm is the kerberos realm of a cell.
573 pathname is the name of a directory to which you wish to authenticate.
574 -noprdb means don't try to determine AFS ID.
575 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
576 (default is Kerberos V)
577 No commandline arguments means authenticate to the local cell.
580 * All of the resource files have been restructured to adhere to
581 a set of rules IBM implemented for loading string resources.
582 These rules had either been forgotten or were not discovered
583 by folks working on the OpenAFS sources. The end result was
584 memory corruption. This is primary item which was preventing
585 the AFS Server from working.
587 * Increased the size of the maximum ticket size stored in a token
588 from 344 bytes to 12,000. Increased the buffers used to convey
589 messages between the pioctl() caller and the SMB Server from
590 1000 bytes to 12,512. The code appeared to have been writing
591 above the top of the stack by quite a few number of bytes.
592 (The increased ticket size is necessary for the next item.)
594 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
595 Instead the raw Kerberos 5 ticket is used in its entirety. This
596 is extremely important as it allows us to use pure Kerberos 5 KDCs
597 as the source of the AFS authentication. The use of up to 12,000 byte
598 tickets will allow tickets produced by all versions of Microsoft
599 Active Directory to be used.
600 - create a user account.
601 - designate it DES only
603 - specify its UPN to be "afs@realm"
604 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
606 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
607 is special when using long file names. (you must use "*.*" and not "*")
608 Instead only enforce it when performing 8dot3 searches.
610 * Fixed the DST problem with creation times being set one hour ahead
612 * Fixed the problem when using \\afs\cell-alias. For example,
613 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
614 for the alias name; instead simply expand the name. One of the
615 symptoms of this problem was a loss of acquired tokens.
617 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
618 of strings. (Only English strings provided.)
620 * Fixed the installer to properly replace in use files.
622 * Fixed the build system to cleanup generated component version files
624 * The release build compiled with MSVC 6.0 compiler to avoid the
625 afsd_service.exe shutdown crash. This does not solve the problem
626 but simply avoids it for the time being.
630 * fix afslogon.dll to not corrupt memory when High Security mode
633 * fix afsd_service.exe to not attempt to restore the stack when
634 an exception occurs. (not safe in multi-threaded programs)
636 * fix uninstaller to properly remove the CRT and MFC DLLs
638 * remove a Message Box from afscreds.exe when getcellconfig()
639 fails on a kerberos realm which is not a cell
641 The following is a list of changes to the OpenAFS for Window client
644 * "fs setserverprefs" will leave afsd service deadlocked
646 * "vos listaddrs" will core dump
648 * installer sets the appropriate keys to support Integrated Logon
650 * installer disables the "Find Lana by Name" functionality as it
651 was causing headaches for many users
653 * fix the intermittent crash of the power management thread when
654 shutting down the AFS Client Service
656 * optimizes the obtain drive mount list functionality which is
657 executed every time the mount tab in afscreds.exe and afs_config.exe
658 are refreshed. (this happens a lot)
660 * fix the service shutdown logic. add the STOP_PENDING state
661 and do not accept additional service events after we declare
664 The following is a list of changes to the OpenAFS for Window client
667 * flexelint was run against the source tree and hundreds (perhaps
668 thousands) of corrections were applied to ensure prototypes
669 were in use; types were used consistently; variables were
670 initialized; unused variables were removed; etc.
672 * A wide variety of instrumentation was added including the
673 ability to produce a stack trace from within afsd_service.exe
676 * Dynamic configuration of the RDRtimeout value based upon the
677 LanMan Workstation Session Timeout
679 * The mount root no longer needs to be called "/afs". This
680 is now set by a registry value "MountRoot" within the key
681 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
683 * The cell list is now only read out of afsdcell.ini when the
684 file changes instead of each time a cell is resolved.
686 * Thread synchronization was added to cm_server.c and ktc_nt.c
688 * All calls to GlobalAlloc()/GlobalFree() were replaced with
689 calloc()/free(). The Global functions were needed on Windows 3.x
690 but have caused a variety of problems on the Win32 platforms.
691 Avoiding them is highly recommended by several Microsoft
692 Knowledgebase articles
694 * Support for Symbolic Links added to the AFS Shell Extension
696 * Added a registry value "OverlayEnabled" to determine if
697 Shell Extension Overlays should be enabled.
698 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
700 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
701 separate trees for checked and free builds. Build system supports
702 a custom directory src\WINNT\extra which can be used as a grafting
703 location of organization specific additions to the build tree.
705 * New installer built using NSIS 2.0.
707 * Named all kernel objects in order to allow them to be monitored
708 with tools such as SysInternals' ProcExp.exe.
710 * Introduced new EventLog framework for AFSD
712 * Introduced Power Management interface to AFSD for Standby and
713 Hibernate modes to allow cache to be flushed prior to network
716 * Utilize Win32 DNSQuery API instead of internal routines. This
717 allows DNS SRV queries to be sent to all current domain name
718 servers. Not just one specified in an INI file. DNS is now
721 * "NetbiosName" registry value may be used to specify a fixed
722 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
723 when the loopback adapter is in use. If you need to use the
724 old notation with a loopback adapter installed specify a registry
727 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
729 * Refactor all modules which depend on LAN Adapter and NetbiosName
730 determination in a new library: lanahelper.lib. This allows for
731 consistent behavior throughout the product.
733 * Move the afsd.log and afsd_init.log files to the directory specified
734 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
735 for services. Added the Date to the log entries.
737 * New registry value "RxMaxMTU" used to limit the size of the RX
738 packets sent by the AFS Client Service to the Server. In order
739 to enable OpenAFS to work across the Cisco IPSec VPN the packet
740 size must be restricted to 1264 or smaller. The latest NSIS
741 installer sets a value of 1260 by default.
743 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
744 packets. This is not needed in order to work across the Cisco
745 VPN but might be needed for other network environments. This
746 value is not set by the NSIS installer.
748 * New registry value "HideDotFiles" is used to apply the Hidden
749 attribute to files whose names begin with a '.'. This value
750 is set by the NSIS installer.
752 * New registry value "MaxMpxRequests" allows the maximum number
753 of multiplexed sessions to be configured at run time. This
754 value is not set by the NSIS installer. The default value is
757 * New registry value "MaxVCPerServer" allows the maxmimum number
758 of VCs per server to be configured at run time. This value is
759 not set by the NSIS installer. The default value is 100.
761 * New registry value "AllSubmount" allows the "all" submount to
762 be disabled by setting its value to 0x00.
764 * Allow cells names to be valid mount points
765 \\<netbiosName>\<cellname>
767 * Store the active state of drive mappings in order for afscreds.exe
768 to restore them upon startup
770 * Add exception handling to generate a Stack Trace to the afsd_init.log
771 file if one happens to occur.
773 * Add lots of logging to help detect the cause of invalid SMB packets
775 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
776 conversion of Kerberos 5 "afs" service tickets. Supports auto-
777 renewal of expiring tokens as long as afscreds.exe is running.
779 * New afscreds.exe command line options:
781 -M = renew drive maps
782 -N = ip address change detection
785 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
786 determines whether or not MIT Kerberos for Windows should be used
787 to obtain tokens via Kerberos 5 tickets.
789 * New registry value "AfscredsShortcutParams" in
790 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
791 determines the command line parameters to be specified when "fixing"
792 the AFS Shortcut in the user's startup folder.
794 * The "ShowTrayIcon" registry value has been moved from
795 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
796 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
798 * The <cell name> registry values used to store the token expiration
799 reminders have been moved from
800 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
801 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
803 * Obtain the Logon User Name from the Explorer key when available
805 * new text document doc\txt\winnotes\registry.txt lists all registry
806 values used by OpenAFS (excluding the AFS Server)
808 * BUG: rx_securityClass objects were not properly reference
809 counted and were never freed.
811 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
812 would be generated. The existence of a server does not imply
813 that it is not down. If all of the servers for a cell are down
814 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
817 * BUG: the directory name lookup cache failed to free the entries
818 in the cache when the name cache entries cycled. The entries
819 in the cache would become dereferenced without being freed.
821 * BUG: fs setserverprefs could be executed without Administrator
824 * BUG: the number of allocated NCB objects (100) exceeded the number
825 which could actually be waited upon by the kernel (64). Any objects
826 which were utilized above the limit could never have event completions
829 * BUG: smb_username_t objects were not being reference counted and
830 were not properly freed.
832 * BUG: smb_tid_t objects could under unusual circumstances be freed
833 before they were no longer referenced.
835 * BUG: smb_fid_t object pointer were frequently used even when
836 their value could be NULL. They were not properly released and
837 therefore they were never freed.
839 * BUG: smb_packet_t data structures were not completely initialized
842 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
843 Denied" because that causes the Explorer Shell to try again until
844 access is obtained. Instead return "Remote Resources" which allows
845 the shell to move on and treat the error as transient.
847 * BUG: when initializing the NCBreturns structure, separate Event objects
848 were created for each NCB although a single Event object was supposed
851 * BUG: smb_dirSearch_t objects were not being properly referenced counted
854 * BUG: smb_tran2Packet_t objects were not being properly referenced
857 * BUG: directory path creation did not handle the case of multiple
858 directories requiring creation in one attempt
860 * BUG: SMB requests which required an Extended Response were ignored.
861 This prevented some files from being written to AFS volumes.
863 * BUG: character strings were being freed even after they were
864 inserted into in use data structures
866 * BUG: inconsistent usernames were used when High Security mode was
867 enabled. (there is still much to do in this area)
869 * BUG: pioctl() calls which require out of band RPC operations were
870 susceptible to race conditions when performed by multiple processes
872 * BUG: memory allocation and deallocation crossed instances of the
873 C Runtime Library producing memory leakage and corruption in
874 afscreds and the client configurator.
