2 * provide mechanisms to force the use of krb524d for Kerberos 5
3 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
4 there is a new registry value "Use524" and for aklog.exe a new
5 command line parameter "-m".
7 * Fix the pattern matching algorithm to properly match patterns
10 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
11 which is used by both the original function and the new
12 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
13 creation of HardLinks in addition to Renaming. smb_Link()
14 is a new function which creates HardLinks via cm_Link().
15 cm_Link() is a new vnodeops function which creates links
18 smb_ReceiveNTRename() does not support the File Copy and
19 Move Cluster Information operations described in its interface.
20 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
22 * When opening files via symlinks, we should follow the symlinks
23 until we reach the actual file stat cache entry. The stat cache
24 entry of the file should then be stored in the FID instead of
25 stat scache entry of the symlink.
27 * return bad operation errors for all unimplemented functions
28 even if we do not know the functions exist.
30 * Log bad packets and unknown operation packets to the trace log
32 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
35 * Update list of known CIFS operations to include all those listed
36 in CIFS-TR-1p00_FINAL.pdf.
39 * A new Windows authorization group "AFS Client Admins" is now
40 created and populated with the members of the "Administrators"
41 group. The group is used to determine which accounts on the
42 machine may be used to modify the AFS Client Configuration via
43 the UI and command line tools. afs_config.exe, fs.exe,
45 * Modify the WinLogon Logoff Event Handler to query NT4 domain
46 controllers for the remote profile path if Active Directory
47 services are not available.
49 * Fix aklog.exe to not add the AFS ID to the username
51 * PTS registration of new users to foreign cells has been added to
54 * The cm_Daemon thread is used to perform checks for
55 down servers, up servers, volumes, callback expirations,
56 lock maintenance and token expiration. Due to a gaff in
57 larger integer division the thread never performed any
58 work. Instead the current time computation would always
59 be less then the trigger times. This had an adverse affect
60 on the client's ability to maintain communication with servers,
61 keep volumes up to date, and flush user tokens and acls
62 when they have expired. This was broken when the 1.3 branch
63 was modified to support VC7 which no longer included
66 * An initialization problem with the Freelance code was
67 detected while fixing the callbackRequest. The cm_rootSCachep
68 object is obtained during afsd_InitDaemons() but the callback
69 information is incomplete. The callback information will not
70 be obtained until cm_MergeStatus is called from within
71 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
72 test for the conditions under which the callback information
75 * Reports have been filed indicating that callbacks were
76 being lost. An examination of the code indicated that the
77 cm_server_t objects were not being properly reference
78 counted by the cm_scache_t and cm_callbackRequest_t objects.
79 In particular, the cm_server_t objects may have been freed
80 from beneath the cm_conn_t objects.
82 All of the reference counting is now done via the functions:
87 this improves the ability to track the referrals.
89 Each cm_BeginCallbackGranting Call now allocates a reference
90 to the cm_server_t. The cm_EndCallbackGrantingCall either
91 frees the reference or transfers it to the cm_scache_t
92 cbServerp field. These are then appropriately tracked
93 through the cm_Analyze call.
95 * Ensure that the dnlc hash table is the same size as the
96 dir name hash table (as per original author's note).
97 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
98 for compatibility with 64-bit systems.
100 * fix smb_ApplyV3DirListPatches to properly apply the hidden
101 attribute to dotfiles when the infoLevel < 0x101 and
102 cm_SyncOp has failed.
104 * Fix the Freelance registry initialization code. There
105 was a possibility that some systems could end up with
106 garbage in the registry during a clean install.
109 * file and directory names beginning with "." will now be given the
110 hidden attribute when the volume access is anonymous. this matches
111 the behavior when the volume access is via an authenticated user.
113 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
114 key. When a change occurs mark the root.afs data as invalid and
115 for it to be reloaded on the next access. This allows administrators
116 to modify the mount point list without restarting the service.
118 The freelance client used to provide a fake modification time for
119 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
120 Added code to extract the last modification time of the Freelance
121 registry key and use that instead. The time now represents the
122 most recent mount point change.
124 * PTS registration of new users to foreign cells has been added to
127 * Additional Cache Control and Credential Manager options have been
128 added to the WiX installer. See deployment guide for details.
130 * The CachePath setting is now optionally a REG_EXPAND_SZ type
132 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
135 * The loopback installation code may have had a problem updating the
136 %ETC%\HOSTS file which could have resulted in a premature failure.
137 Work around code has been added for the case where the file cannot
140 * The default max chunksize was increased from 15 (32K) to 17 (128K)
141 because Windows sends 64K blocks when using overlapped writes.
143 * The default number of server threads was increased from 4 to 25 to
144 better handle overlapped writes.
146 * The "AfscredsShortcutParams" registry value was not being properly
147 loaded by afscreds.exe. Therefore, the default value was always being
148 used instead of the value set by the installer.
150 * Windows XP provides downgrade attack detection to prevent an attacker
151 from being able to force the use of NTLM simply by disrupting
152 communication with the KDC. This attack cannot exist between the
153 Windows CIFS client and the AFS Client Service. Therefore, when a
154 downgrade has been detected the afs pioctl library will force the
155 establishment of a new CIFS connection using NTLM.
157 * A locking error was discovered surrounding all references to volume
158 server lists within the cm_cell.c source file.
160 * The logged into Windows username was incorrect on Terminal Server
163 * A new registry value "NonPersistentCaching" was added to the service
164 parameters key. When set to a non-zero value, the afs cache is stored
165 in the Windows paging file. There are two limitations to choosing
167 1. when persistent caching is implemented it won't work with
168 this flag set since there will be nothing to persist.
169 2. with this flag set the initial paging allocation cannot be
170 changed while the service is running
172 * An initialization bug was discovered in aklog.exe which affected users
173 who have a domain name for their afs servers which could not be mapped
177 * afs_config.exe now validates cell names against DNS in addition
178 to the CellServDB file.
180 * In order to allow the freelance client to connect to a volume with ID
181 equal to 1 on the default cell we changed the fake root.afs volume ID
182 once again. This time we choose 0xFFFFFFFF. In addition, we change
183 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
184 It will now be impossible for a volume ID to match that of another
185 cell unless the client is connected to 0xFFFFFFFD cells. That should
186 be enough room for growth.
188 * Fix "fs mkmount" command to work with UNC paths and when
189 started from non-AFS drives. It is now possible to create a mount
190 point in the freelance fake root.afs volume with the command
192 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
196 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
197 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
199 * The algorithm used to re-attempt access to the servers associated with
200 a volume has been altered to properly address the case in which all
201 servers have been marked down. The previous algorithm did not reset
202 the server's down flags so the servers were never actually retried.
203 This caused a problem with active volumes if the network connectivity
204 was lost as could be the case with a network cable removal, wireless
205 drop, or laptop hibernation. With the fix volume access is restored
206 almost instantenously when network connectivity becomes available.
208 * Support for SMB/CIFS browsing has been added to the AFS Client Service
209 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
210 listing of AFS submounts and freelance mount points. Support for
211 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
212 significantly enhances the behavior of AFS volumes within the Explorer
213 Shell. For instance, "AFS" now shows up as server in the Explorer
214 with each submount or freelance mount point visible as a share.
215 The right click menu in each folder now works with full functionality
216 on a consistent basis.
218 * The network provider can be configured to have different behavior
219 depending on the domain that the user logs into. These settings are
220 only relevant when using integrated login. A domain refers to an
221 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
222 local machine (i.e. local account logins). The domain name that is
223 used for selecting the domain would be the domain that is passed into
224 the NPLogonNotify function of the network provider. (see registry.txt
227 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
228 "Authentication Cell" which may be used to specify a default
229 authentication cell for afscreds.exe which is different from
230 the default cell for the AFS Client Service daemon.
232 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
233 afslogon.dll moved to %WINDIR%\System32\.
234 New registry entries added to register the dll for Winlogon events.
236 The logoff event will now force a call to ktc_ForgetAllTokens()
237 using the context of the user being logged off as long as the
238 user's profile is not loaded from within AFS. If the profile
239 was loaded from AFS we can't release the tokens since the Logoff
240 event is triggered prior to the profile being written back to
241 the its source location. This is now performed in an XP SP2
244 * Windows XP SP2 Internet Connection Firewall interoperability
247 * The %WINDIR%\afsdsbmt.ini contains four sections:
248 Submounts, Drive Mappings, Active Maps and CSC Policies.
249 The Submounts and CSC policies are now stored in the registry under
250 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
251 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
252 The Drive Mappings and Active Maps are stored in the registry under
253 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
254 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
256 There is no automatic migration of this data as it would be impossible
257 to consistently migrate data to user profiles which may not be active
258 when the machine is updated.
260 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
261 fake root.afs volume. For the same reasons as for the cellservdb file,
262 this information should not be in %WINDIR%. This information is now
263 kept under the registry key
264 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
266 The data from the afs_freelance.ini file will be automatically
267 migrated to the registry on first execution of afsd_service.exe
269 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
270 troublesome for several reasons. One, it is confusing for those who
271 expect the file to be named "CellServDB" instead of "afsdcell.ini".
272 Two, this file is not a Windows Profile formatted file. Three,
273 applications should not be reading or writing to %WINDIR%. It causes
274 problems for Windows Terminal Server.
276 The new location of CellServDB will be the OpenAFS Client install
277 directory which is by default C:\Program Files\OpenAFS\Client and can
278 be determined by querying the registry for
279 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
281 The existing afsdcell.ini will be migrated by the NSIS installer.
282 The Wix installer must still be updated to do the same.
284 * Change NSIS installer to use DNS by default; to remove Integrated Logon
285 High Security mode; and to add Terminal Services compatibility registry
286 entries to allow the OpenAFS tools to find the afsdcell.ini and other
287 configuration files in %WINDIR%.
289 * Add support for authenticated SMB connections. This will remove
290 the need for high security mode in most situations. Both NTLM
291 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
292 only NTLM can be used even though Kerberos is now supported. The
293 reason is that it is not possible to construct a service principal
294 which is unique to each individual machine.
296 SMB Extended Auth does not work on XP SP2 unless one of two registry
297 modifications are made:
299 (1) To disable the check for matching host names on loopback connections
300 set this key. This does not require a reboot:
302 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
303 "DisableLoopbackCheck"=dword:00000001
305 (2) To add the AFS SMB/CIFS service name to an approved list. This
306 does require a reboot:
308 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
309 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
311 afsd_service.exe will automatically add the current Netbios Name
312 to the BackConnectionHostNames list and then temporarily disable
313 the loopback check for one cycle of startup/shutdown of the service.
314 We assume most folks do not start/stop without a reboot so this
315 will be adequate in most cases.
317 * Fix security hole in afslogon.dll which allowed passwords to be
318 sent in clear text to the KDC in a misformed principal name.
320 * Fix cm_GetCell() to properly handle expired dns entries
323 * If Freelance mode is active and the afs_freelance.ini
324 file does not exist, do not create an empty file.
325 Instead create a file containing ro and rw mountpoints
326 to the default cell using the standard conventions.
328 * Modify the Freelance support to handle the ability
329 to create rw mount points in the fake root.afs volume.
331 * Changed the RPC mechanism used for token setting from
332 named pipes to local. Use of named pipes can be restored
333 by setting the environment variable AFS_RPC_PROTSEQ to
336 Named pipes were required when a Windows 9x system was
337 using a NT system in gateway mode which is incompatible
338 with our use of local loopback adapters.
340 * In afscreds.exe, if a username of the form user@REALM is
341 specified and no password is specified, do not perform a
342 kinit operation. Only perform the aklog functionality.
344 * Add a new registry value which allows the number of processors
345 on which afsd_service.exe executes to be restricted. Valid
346 values are 1..numOfProcessors
348 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
352 * A second MSI based installer option is now available.
354 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
355 request tickets for user/instance@REALM instead of just user@REALM
357 * Modify the Power Management Notify routine to wait for the Hard Dead
358 timeout period instead of a fixed 19 seconds. With the longer timeout
359 periods Hibernation and Standby could never succeed when network
360 connectivity is not available.
362 * The following fs.exe commands are now restricted to Administrator:
363 - checkservers with a non-zero timer value
366 - sysname with a new sysname list
375 setting the default sysname for a machine should be done via the
376 registry and not via "fs sysname".
378 * NSIS installer adds options to install Debugging Symbols
379 and the Microsoft Loopback Adapter; the user is now also
380 given the ability to select the afscreds.exe startup options.
382 * Build system modified to generate symbols for FREE (aka RELEASE)
383 builds as well as CHECKED (aka DEBUG) builds
385 * Sites which have a volume ID of 0x20000001 assigned to their
386 root.cell volumes have been experiencing problems with accessing
387 the root.cell volume of their cell when Freelance mode has been
388 active. This was because 0x20000001 was assigned to the fake
389 root.afs volume created by freelance. The fake volume id is
390 now set to 0x00000001 to prevent conflicts.
392 * The timeout logic in the AFS Client Service has been wrong
393 for sometime. It is based on two different assumptions.
394 First, the SMB client timeout is a fix value as was the case
395 with OS/2 Lan Manager. This assumption is incorrect. The
396 SMB timeout in Windows is a dynamic value computed based upon
397 a fixed minimum timeout to which is added time based upon the
398 size of the request and the performance characteristics of
399 the connection. Second, it is the responsibility of the
400 SMB Server to enforce the timeout requirements of the client.
401 This is untrue. The SMB Server cannot be expected to know
402 the requirements of the client. More importantly, if the
403 SMB server uses the SMB client timeout as a value to restrict
404 its behavior as an RX client, the performance characteristics
405 of the local SMB session would be used to prematurely terminate
406 WAN connections with significantly different performance
409 The timeout logic has therefore been modified in the following
411 . the Lan Manager Workstation (SMB) Session Timeout is used only
412 as a basis for configuring the Connection Dead Timeout
413 and Hard Dead Timeout values. The Connection Dead Timeout
414 must be at least 15 seconds longer than the SMB Timeout
415 and the Hard Dead Timeout must be at least double the
416 Connection Dead Timeout.
417 . New registry entries have been added to allow the Connection
418 Dead Timeout and Hard Dead Timeout values independent of the
419 Lan Manager Workstation Session Timeout
420 . The test to enforce the SMB Client Timeout has been removed.
422 One of the side-effects of removing the enforcement of the SMB
423 Client Timeout is that regardless of whether or not the SMB client
424 is available to receive the response (and how would the SMB server
425 know) the RX protocol response can be used to update the AFS
426 Client Service state for ready access by future SMB client
429 This should be the end of the "Server paused or restarting messages"
431 * Add support for arbitrary UNC paths to the pioctl() support.
432 This enables the fs commands as well as the AFS Shell Extension
433 to work correctly when UNC paths are being used.
435 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
436 DNS if the cell configuration cannot be determined via CellServDB
438 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
439 are ever set more than once at a time
441 * Fix the management of lists of cm_cell_t structures when using
442 DNS to lookup cell information. The previous code would fail to
443 reuse the same cellID for a cell if DNS was used more than once
444 for a given cell name. When the ttl expired, a single cm_cell_t
445 could be inserted into the cm_allCellsp list more than once
446 producing a loop. In addition, the vlServerp list belonging to
447 the cell was not freed resulting in improper refCounting of the
450 * Add DNS support to cm_IoctlNewCell() which previous only examined
453 * Add cm_FreeServer() function and call it from cm_FreeServerList()
454 to properly garbage collect cm_server_t objects
456 * Add numVCs variable to smb.c to track the number of smb_vc_t
457 objects created and use it to initialize the vcID field which
458 previously was set to 0 in all objects resulting in FindByID
461 * Fixed DNS lookups to work consistently throughout the OpenAFS
462 product instead of just from within the afsd_service.exe
464 * Added a runtime check to ensure that AFS Client Service SMB
465 Server is accepting connections before attempting to mount
468 * Read IP addresses for volume servers out of the CellServDB
469 file if gethostbyname() on the hostname fails.
471 * Fix getcellconfig() to populate both the Hostnames as well
472 as IP addresses when loading cell data via DNS
474 * Increase the Connection Dead Time to 50 from 20 seconds
475 Increase the Hard Dead Time to 120 from 40 seconds
476 (matches the Unix values)
478 * Fixed an assertion validating the number of allocated NCBs
480 * Fixed the build environment to consistently build for
481 Windows 2000 and above. (APPVER = 5.0)
483 * Fixed rx_debug to properly validate the receipt in incoming
484 data with select() and recvfrom(). Do not copy data out of
485 the socket buffer unless success is indicated.
488 * afsd_service.exe will now display a message box to the
489 desktop when it terminates due to an IP Address Change.
491 * installer no longer deletes AFS Server configuration data
494 * installer generates a warning dialog if the RPC service
495 is not properly configured
497 * installer compressed with lzma instead of bzip2
499 * afsd_service.exe shutdown crash solved once and for all
501 * reference counting of smb_vc_t data structures improved
503 * name space collision of smb_fid_t event objects corrected
505 * the output of "fs memdump" is now written to
506 %WINDIR%\TEMP\afsd_alloc.log
508 * the file TaAfsApp_1033.dll is now properly installed allowing
509 the User Manager to start
511 * a new algorithm is used for computing filename pattern matches
513 * afscreds.exe now accepts user names containing instance
516 * Fix the Directory Name Lookup Cache to be case-sensitive.
517 This is crucial in environments in which a Windows client
518 is accessing a directory with more than one filename that
519 differs only by case. If the directory contains "FOO"
520 and "Foo". You want "DEL Foo" to delete the correct one.
521 We still have a problem in that "DEL foo" will delete a
522 random filename. This will be addressed in a future release.
524 * Fix afscreds.exe -M option (renewMaps) to work when High
525 Security mode is off. Also, remember to disable the ActiveMap
526 flag in afsdsbmt.ini when a drive mapping is removed.
528 * Updates to NSIS installer script. AFS Server configuration
529 data will not be destroyed on un-install or re-install.
530 Use a better compression algorithm.
532 * afslogon.dll now uses KFW to obtain tokens when available
534 * afslogon.dll when given an all uppercase username will
535 attempt to authenticate with both the uppercase name
536 and an all lowercase variation
538 * DST modification removed. The fix appears to make things
539 worse after a reboot of the machine.
541 * fs.exe: added "cscpolicy" which is used to
542 change client side caching policy for AFS shares
544 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
545 [-documents] [-disable] [-help]
547 * Several uninitialized variables have been initialized
549 * It is now possible to obtain tokens using cross realm
550 Kerberos within afscreds.exe:
552 user: jaltman@ATHENA.MIT.EDU
554 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
555 will will in turn be used to obtain afs@DEMENTIA.ORG.
556 The resulting token will be stored with the display name
557 jaltman@ATHENA.MIT.EDU@dementia.org
559 * aklog.exe has been added to the client
561 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
562 [[-p | -path] pathname]
566 -d gives debugging information.
567 krb_realm is the kerberos realm of a cell.
568 pathname is the name of a directory to which you wish to authenticate.
569 -noprdb means don't try to determine AFS ID.
570 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
571 (default is Kerberos V)
572 No commandline arguments means authenticate to the local cell.
575 * All of the resource files have been restructured to adhere to
576 a set of rules IBM implemented for loading string resources.
577 These rules had either been forgotten or were not discovered
578 by folks working on the OpenAFS sources. The end result was
579 memory corruption. This is primary item which was preventing
580 the AFS Server from working.
582 * Increased the size of the maximum ticket size stored in a token
583 from 344 bytes to 12,000. Increased the buffers used to convey
584 messages between the pioctl() caller and the SMB Server from
585 1000 bytes to 12,512. The code appeared to have been writing
586 above the top of the stack by quite a few number of bytes.
587 (The increased ticket size is necessary for the next item.)
589 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
590 Instead the raw Kerberos 5 ticket is used in its entirety. This
591 is extremely important as it allows us to use pure Kerberos 5 KDCs
592 as the source of the AFS authentication. The use of up to 12,000 byte
593 tickets will allow tickets produced by all versions of Microsoft
594 Active Directory to be used.
595 - create a user account.
596 - designate it DES only
598 - specify its UPN to be "afs@realm"
599 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
601 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
602 is special when using long file names. (you must use "*.*" and not "*")
603 Instead only enforce it when performing 8dot3 searches.
605 * Fixed the DST problem with creation times being set one hour ahead
607 * Fixed the problem when using \\afs\cell-alias. For example,
608 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
609 for the alias name; instead simply expand the name. One of the
610 symptoms of this problem was a loss of acquired tokens.
612 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
613 of strings. (Only English strings provided.)
615 * Fixed the installer to properly replace in use files.
617 * Fixed the build system to cleanup generated component version files
619 * The release build compiled with MSVC 6.0 compiler to avoid the
620 afsd_service.exe shutdown crash. This does not solve the problem
621 but simply avoids it for the time being.
625 * fix afslogon.dll to not corrupt memory when High Security mode
628 * fix afsd_service.exe to not attempt to restore the stack when
629 an exception occurs. (not safe in multi-threaded programs)
631 * fix uninstaller to properly remove the CRT and MFC DLLs
633 * remove a Message Box from afscreds.exe when getcellconfig()
634 fails on a kerberos realm which is not a cell
636 The following is a list of changes to the OpenAFS for Window client
639 * "fs setserverprefs" will leave afsd service deadlocked
641 * "vos listaddrs" will core dump
643 * installer sets the appropriate keys to support Integrated Logon
645 * installer disables the "Find Lana by Name" functionality as it
646 was causing headaches for many users
648 * fix the intermittent crash of the power management thread when
649 shutting down the AFS Client Service
651 * optimizes the obtain drive mount list functionality which is
652 executed every time the mount tab in afscreds.exe and afs_config.exe
653 are refreshed. (this happens a lot)
655 * fix the service shutdown logic. add the STOP_PENDING state
656 and do not accept additional service events after we declare
659 The following is a list of changes to the OpenAFS for Window client
662 * flexelint was run against the source tree and hundreds (perhaps
663 thousands) of corrections were applied to ensure prototypes
664 were in use; types were used consistently; variables were
665 initialized; unused variables were removed; etc.
667 * A wide variety of instrumentation was added including the
668 ability to produce a stack trace from within afsd_service.exe
671 * Dynamic configuration of the RDRtimeout value based upon the
672 LanMan Workstation Session Timeout
674 * The mount root no longer needs to be called "/afs". This
675 is now set by a registry value "MountRoot" within the key
676 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
678 * The cell list is now only read out of afsdcell.ini when the
679 file changes instead of each time a cell is resolved.
681 * Thread synchronization was added to cm_server.c and ktc_nt.c
683 * All calls to GlobalAlloc()/GlobalFree() were replaced with
684 calloc()/free(). The Global functions were needed on Windows 3.x
685 but have caused a variety of problems on the Win32 platforms.
686 Avoiding them is highly recommended by several Microsoft
687 Knowledgebase articles
689 * Support for Symbolic Links added to the AFS Shell Extension
691 * Added a registry value "OverlayEnabled" to determine if
692 Shell Extension Overlays should be enabled.
693 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
695 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
696 separate trees for checked and free builds. Build system supports
697 a custom directory src\WINNT\extra which can be used as a grafting
698 location of organization specific additions to the build tree.
700 * New installer built using NSIS 2.0.
702 * Named all kernel objects in order to allow them to be monitored
703 with tools such as SysInternals' ProcExp.exe.
705 * Introduced new EventLog framework for AFSD
707 * Introduced Power Management interface to AFSD for Standby and
708 Hibernate modes to allow cache to be flushed prior to network
711 * Utilize Win32 DNSQuery API instead of internal routines. This
712 allows DNS SRV queries to be sent to all current domain name
713 servers. Not just one specified in an INI file. DNS is now
716 * "NetbiosName" registry value may be used to specify a fixed
717 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
718 when the loopback adapter is in use. If you need to use the
719 old notation with a loopback adapter installed specify a registry
722 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
724 * Refactor all modules which depend on LAN Adapter and NetbiosName
725 determination in a new library: lanahelper.lib. This allows for
726 consistent behavior throughout the product.
728 * Move the afsd.log and afsd_init.log files to the directory specified
729 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
730 for services. Added the Date to the log entries.
732 * New registry value "RxMaxMTU" used to limit the size of the RX
733 packets sent by the AFS Client Service to the Server. In order
734 to enable OpenAFS to work across the Cisco IPSec VPN the packet
735 size must be restricted to 1264 or smaller. The latest NSIS
736 installer sets a value of 1260 by default.
738 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
739 packets. This is not needed in order to work across the Cisco
740 VPN but might be needed for other network environments. This
741 value is not set by the NSIS installer.
743 * New registry value "HideDotFiles" is used to apply the Hidden
744 attribute to files whose names begin with a '.'. This value
745 is set by the NSIS installer.
747 * New registry value "MaxMpxRequests" allows the maximum number
748 of multiplexed sessions to be configured at run time. This
749 value is not set by the NSIS installer. The default value is
752 * New registry value "MaxVCPerServer" allows the maxmimum number
753 of VCs per server to be configured at run time. This value is
754 not set by the NSIS installer. The default value is 100.
756 * New registry value "AllSubmount" allows the "all" submount to
757 be disabled by setting its value to 0x00.
759 * Allow cells names to be valid mount points
760 \\<netbiosName>\<cellname>
762 * Store the active state of drive mappings in order for afscreds.exe
763 to restore them upon startup
765 * Add exception handling to generate a Stack Trace to the afsd_init.log
766 file if one happens to occur.
768 * Add lots of logging to help detect the cause of invalid SMB packets
770 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
771 conversion of Kerberos 5 "afs" service tickets. Supports auto-
772 renewal of expiring tokens as long as afscreds.exe is running.
774 * New afscreds.exe command line options:
776 -M = renew drive maps
777 -N = ip address change detection
780 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
781 determines whether or not MIT Kerberos for Windows should be used
782 to obtain tokens via Kerberos 5 tickets.
784 * New registry value "AfscredsShortcutParams" in
785 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
786 determines the command line parameters to be specified when "fixing"
787 the AFS Shortcut in the user's startup folder.
789 * The "ShowTrayIcon" registry value has been moved from
790 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
791 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
793 * The <cell name> registry values used to store the token expiration
794 reminders have been moved from
795 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
796 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
798 * Obtain the Logon User Name from the Explorer key when available
800 * new text document doc\txt\winnotes\registry.txt lists all registry
801 values used by OpenAFS (excluding the AFS Server)
803 * BUG: rx_securityClass objects were not properly reference
804 counted and were never freed.
806 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
807 would be generated. The existence of a server does not imply
808 that it is not down. If all of the servers for a cell are down
809 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
812 * BUG: the directory name lookup cache failed to free the entries
813 in the cache when the name cache entries cycled. The entries
814 in the cache would become dereferenced without being freed.
816 * BUG: fs setserverprefs could be executed without Administrator
819 * BUG: the number of allocated NCB objects (100) exceeded the number
820 which could actually be waited upon by the kernel (64). Any objects
821 which were utilized above the limit could never have event completions
824 * BUG: smb_username_t objects were not being reference counted and
825 were not properly freed.
827 * BUG: smb_tid_t objects could under unusual circumstances be freed
828 before they were no longer referenced.
830 * BUG: smb_fid_t object pointer were frequently used even when
831 their value could be NULL. They were not properly released and
832 therefore they were never freed.
834 * BUG: smb_packet_t data structures were not completely initialized
837 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
838 Denied" because that causes the Explorer Shell to try again until
839 access is obtained. Instead return "Remote Resources" which allows
840 the shell to move on and treat the error as transient.
842 * BUG: when initializing the NCBreturns structure, separate Event objects
843 were created for each NCB although a single Event object was supposed
846 * BUG: smb_dirSearch_t objects were not being properly referenced counted
849 * BUG: smb_tran2Packet_t objects were not being properly referenced
852 * BUG: directory path creation did not handle the case of multiple
853 directories requiring creation in one attempt
855 * BUG: SMB requests which required an Extended Response were ignored.
856 This prevented some files from being written to AFS volumes.
858 * BUG: character strings were being freed even after they were
859 inserted into in use data structures
861 * BUG: inconsistent usernames were used when High Security mode was
862 enabled. (there is still much to do in this area)
864 * BUG: pioctl() calls which require out of band RPC operations were
865 susceptible to race conditions when performed by multiple processes
867 * BUG: memory allocation and deallocation crossed instances of the
868 C Runtime Library producing memory leakage and corruption in
869 afscreds and the client configurator.
