2 * Added support for VL_GetEntryByNameN(). Still need to add
3 support for VL_GetEntryByNameU() for multi-homed support.
5 * Fix a deadlock situation in afscreds.exe when canceling an
6 auto-generated Obtain Tokens dialog
9 * Fix the locking of objects during Directory Searches in the
10 SMB/CIFS server. The failure to properly lock the reference
11 counts was resulting in the premature freeing of smb_dirSearch_t
12 objects while they were still in use by the SMB/CIFS client.
13 This does not solve the "Invalid Handle" problem.
15 * Fix Find Cell By Name pioctl call to return a valid cell
16 name for the Freelance fake root.afs volume.
17 "Freelance.Local.Root".
19 * Fix the Explorer Shell Extension Symlinks->Add operation.
20 The dialog template was missing and the link destination
23 * Add support for symlinks to Freelance root.afs volume
24 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
25 <number> = "<linkname>:<relative-path>."
26 Use symlink.exe to create, list, or remove
28 * Remove the fallback to the use of KFW's KRB4 library when obtaining
29 tokens. We never obtain KRB4 tickets.
31 * Fix AFS Client Configuration Control Panel to support new SysName
33 * Fix a bug in afsd_service.exe which could result in the SysName
34 not being read from the registry.
37 * Add code to block the issuance of AFS tokens by aklog.exe or
38 afscreds.exe when the Kerberos 5 principal name contains a dot.
40 * Modify the IsAdmin() function to always treat the local SYSTEM
41 account as an AFS client administrator. Affects fs.exe and
44 * Modify the internal handling of Quota Exceeded errors
46 * Upgrade all reference count fields in the Windows cache manager
47 and the osi library to use unsigned long instead of signed short.
48 A similar fix has been applied to the afs rpc (rx) library.
50 * fix the Windows cache manager to prevent it from replacing the
51 rx_connection object associated with the cm_conn_t object on each
52 and every operation if "fs crypt" was set. This explains the
53 dramatic performance difference when crypt is used vs clear.
54 The problem: 'cryptall', a boolean flag indicating whether or not
55 "fs crypt" is set, was being compared to the rx_connection
56 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
57 1 != 2 and therefore the rx_connection was always destroyed
58 and replaced on each and every operation.
60 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
61 It is not safe for the cm_conn_t object to not be locked because
62 rx_DestroyConnection might be called from another thread if:
63 - the user's tokens have changed or expired
64 - the crypt mode has changed
66 This fix appears to have also taken care of the problems associated
67 with Overlapped Writes resulting in Delayed Write errors.
69 * fix NSIS installer's AdminGroup.exe to properly create and
70 remove groups when given -create or -remove. The string comparison
73 * fs sysname now accepts a list of sysname values
75 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
76 DWORD which when set to a non-zero value will cause error message
77 text to be output to stderr from the pioctl() routine. Useful in
78 debugging failures of fs.exe, tokens.exe, etc.
80 * added a test to the power management code to only perform a
81 flush operation if there is at least one network adapter which
82 is not a loopback adapter.
84 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
85 "EnableKFW". This value will not be read if the key
86 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
87 value under that key does not.
89 * provide mechanisms to force the use of krb524d for Kerberos 5
90 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
91 there is a new registry value "Use524" and for aklog.exe a new
92 command line parameter "-m".
94 * Fix the pattern matching algorithm to properly match patterns
97 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
98 which is used by both the original function and the new
99 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
100 creation of HardLinks in addition to Renaming. smb_Link()
101 is a new function which creates HardLinks via cm_Link().
102 cm_Link() is a new vnodeops function which creates links
105 smb_ReceiveNTRename() does not support the File Copy and
106 Move Cluster Information operations described in its interface.
107 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
109 * When opening files via symlinks, we should follow the symlinks
110 until we reach the actual file stat cache entry. The stat cache
111 entry of the file should then be stored in the FID instead of
112 stat scache entry of the symlink.
114 * return bad operation errors for all unimplemented functions
115 even if we do not know the functions exist.
117 * Log bad packets and unknown operation packets to the trace log
119 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
122 * Update list of known CIFS operations to include all those listed
123 in CIFS-TR-1p00_FINAL.pdf.
125 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
126 to support the REG_EXPAND_SZ type.
129 * A new Windows authorization group "AFS Client Admins" is now
130 created and populated with the members of the "Administrators"
131 group. The group is used to determine which accounts on the
132 machine may be used to modify the AFS Client Configuration via
133 the UI and command line tools. afs_config.exe, fs.exe,
135 * Modify the WinLogon Logoff Event Handler to query NT4 domain
136 controllers for the remote profile path if Active Directory
137 services are not available.
139 * Fix aklog.exe to not add the AFS ID to the username
141 * PTS registration of new users to foreign cells has been added to
144 * The cm_Daemon thread is used to perform checks for
145 down servers, up servers, volumes, callback expirations,
146 lock maintenance and token expiration. Due to a gaff in
147 larger integer division the thread never performed any
148 work. Instead the current time computation would always
149 be less then the trigger times. This had an adverse affect
150 on the client's ability to maintain communication with servers,
151 keep volumes up to date, and flush user tokens and acls
152 when they have expired. This was broken when the 1.3 branch
153 was modified to support VC7 which no longer included
156 * An initialization problem with the Freelance code was
157 detected while fixing the callbackRequest. The cm_rootSCachep
158 object is obtained during afsd_InitDaemons() but the callback
159 information is incomplete. The callback information will not
160 be obtained until cm_MergeStatus is called from within
161 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
162 test for the conditions under which the callback information
165 * Reports have been filed indicating that callbacks were
166 being lost. An examination of the code indicated that the
167 cm_server_t objects were not being properly reference
168 counted by the cm_scache_t and cm_callbackRequest_t objects.
169 In particular, the cm_server_t objects may have been freed
170 from beneath the cm_conn_t objects.
172 All of the reference counting is now done via the functions:
177 this improves the ability to track the referrals.
179 Each cm_BeginCallbackGranting Call now allocates a reference
180 to the cm_server_t. The cm_EndCallbackGrantingCall either
181 frees the reference or transfers it to the cm_scache_t
182 cbServerp field. These are then appropriately tracked
183 through the cm_Analyze call.
185 * Ensure that the dnlc hash table is the same size as the
186 dir name hash table (as per original author's note).
187 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
188 for compatibility with 64-bit systems.
190 * fix smb_ApplyV3DirListPatches to properly apply the hidden
191 attribute to dotfiles when the infoLevel < 0x101 and
192 cm_SyncOp has failed.
194 * Fix the Freelance registry initialization code. There
195 was a possibility that some systems could end up with
196 garbage in the registry during a clean install.
199 * file and directory names beginning with "." will now be given the
200 hidden attribute when the volume access is anonymous. this matches
201 the behavior when the volume access is via an authenticated user.
203 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
204 key. When a change occurs mark the root.afs data as invalid and
205 for it to be reloaded on the next access. This allows administrators
206 to modify the mount point list without restarting the service.
208 The freelance client used to provide a fake modification time for
209 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
210 Added code to extract the last modification time of the Freelance
211 registry key and use that instead. The time now represents the
212 most recent mount point change.
214 * PTS registration of new users to foreign cells has been added to
217 * Additional Cache Control and Credential Manager options have been
218 added to the WiX installer. See deployment guide for details.
220 * The CachePath setting is now optionally a REG_EXPAND_SZ type
222 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
225 * The loopback installation code may have had a problem updating the
226 %ETC%\HOSTS file which could have resulted in a premature failure.
227 Work around code has been added for the case where the file cannot
230 * The default max chunksize was increased from 15 (32K) to 17 (128K)
231 because Windows sends 64K blocks when using overlapped writes.
233 * The default number of server threads was increased from 4 to 25 to
234 better handle overlapped writes.
236 * The "AfscredsShortcutParams" registry value was not being properly
237 loaded by afscreds.exe. Therefore, the default value was always being
238 used instead of the value set by the installer.
240 * Windows XP provides downgrade attack detection to prevent an attacker
241 from being able to force the use of NTLM simply by disrupting
242 communication with the KDC. This attack cannot exist between the
243 Windows CIFS client and the AFS Client Service. Therefore, when a
244 downgrade has been detected the afs pioctl library will force the
245 establishment of a new CIFS connection using NTLM.
247 * A locking error was discovered surrounding all references to volume
248 server lists within the cm_cell.c source file.
250 * The logged into Windows username was incorrect on Terminal Server
253 * A new registry value "NonPersistentCaching" was added to the service
254 parameters key. When set to a non-zero value, the afs cache is stored
255 in the Windows paging file. There are two limitations to choosing
257 1. when persistent caching is implemented it won't work with
258 this flag set since there will be nothing to persist.
259 2. with this flag set the initial paging allocation cannot be
260 changed while the service is running
262 * An initialization bug was discovered in aklog.exe which affected users
263 who have a domain name for their afs servers which could not be mapped
267 * afs_config.exe now validates cell names against DNS in addition
268 to the CellServDB file.
270 * In order to allow the freelance client to connect to a volume with ID
271 equal to 1 on the default cell we changed the fake root.afs volume ID
272 once again. This time we choose 0xFFFFFFFF. In addition, we change
273 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
274 It will now be impossible for a volume ID to match that of another
275 cell unless the client is connected to 0xFFFFFFFD cells. That should
276 be enough room for growth.
278 * Fix "fs mkmount" command to work with UNC paths and when
279 started from non-AFS drives. It is now possible to create a mount
280 point in the freelance fake root.afs volume with the command
282 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
286 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
287 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
289 * The algorithm used to re-attempt access to the servers associated with
290 a volume has been altered to properly address the case in which all
291 servers have been marked down. The previous algorithm did not reset
292 the server's down flags so the servers were never actually retried.
293 This caused a problem with active volumes if the network connectivity
294 was lost as could be the case with a network cable removal, wireless
295 drop, or laptop hibernation. With the fix volume access is restored
296 almost instantenously when network connectivity becomes available.
298 * Support for SMB/CIFS browsing has been added to the AFS Client Service
299 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
300 listing of AFS submounts and freelance mount points. Support for
301 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
302 significantly enhances the behavior of AFS volumes within the Explorer
303 Shell. For instance, "AFS" now shows up as server in the Explorer
304 with each submount or freelance mount point visible as a share.
305 The right click menu in each folder now works with full functionality
306 on a consistent basis.
308 * The network provider can be configured to have different behavior
309 depending on the domain that the user logs into. These settings are
310 only relevant when using integrated login. A domain refers to an
311 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
312 local machine (i.e. local account logins). The domain name that is
313 used for selecting the domain would be the domain that is passed into
314 the NPLogonNotify function of the network provider. (see registry.txt
317 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
318 "Authentication Cell" which may be used to specify a default
319 authentication cell for afscreds.exe which is different from
320 the default cell for the AFS Client Service daemon.
322 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
323 afslogon.dll moved to %WINDIR%\System32\.
324 New registry entries added to register the dll for Winlogon events.
326 The logoff event will now force a call to ktc_ForgetAllTokens()
327 using the context of the user being logged off as long as the
328 user's profile is not loaded from within AFS. If the profile
329 was loaded from AFS we can't release the tokens since the Logoff
330 event is triggered prior to the profile being written back to
331 the its source location. This is now performed in an XP SP2
334 * Windows XP SP2 Internet Connection Firewall interoperability
337 * The %WINDIR%\afsdsbmt.ini contains four sections:
338 Submounts, Drive Mappings, Active Maps and CSC Policies.
339 The Submounts and CSC policies are now stored in the registry under
340 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
341 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
342 The Drive Mappings and Active Maps are stored in the registry under
343 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
344 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
346 There is no automatic migration of this data as it would be impossible
347 to consistently migrate data to user profiles which may not be active
348 when the machine is updated.
350 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
351 fake root.afs volume. For the same reasons as for the cellservdb file,
352 this information should not be in %WINDIR%. This information is now
353 kept under the registry key
354 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
356 The data from the afs_freelance.ini file will be automatically
357 migrated to the registry on first execution of afsd_service.exe
359 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
360 troublesome for several reasons. One, it is confusing for those who
361 expect the file to be named "CellServDB" instead of "afsdcell.ini".
362 Two, this file is not a Windows Profile formatted file. Three,
363 applications should not be reading or writing to %WINDIR%. It causes
364 problems for Windows Terminal Server.
366 The new location of CellServDB will be the OpenAFS Client install
367 directory which is by default C:\Program Files\OpenAFS\Client and can
368 be determined by querying the registry for
369 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
371 The existing afsdcell.ini will be migrated by the NSIS installer.
372 The Wix installer must still be updated to do the same.
374 * Change NSIS installer to use DNS by default; to remove Integrated Logon
375 High Security mode; and to add Terminal Services compatibility registry
376 entries to allow the OpenAFS tools to find the afsdcell.ini and other
377 configuration files in %WINDIR%.
379 * Add support for authenticated SMB connections. This will remove
380 the need for high security mode in most situations. Both NTLM
381 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
382 only NTLM can be used even though Kerberos is now supported. The
383 reason is that it is not possible to construct a service principal
384 which is unique to each individual machine.
386 SMB Extended Auth does not work on XP SP2 unless one of two registry
387 modifications are made:
389 (1) To disable the check for matching host names on loopback connections
390 set this key. This does not require a reboot:
392 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
393 "DisableLoopbackCheck"=dword:00000001
395 (2) To add the AFS SMB/CIFS service name to an approved list. This
396 does require a reboot:
398 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
399 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
401 afsd_service.exe will automatically add the current Netbios Name
402 to the BackConnectionHostNames list and then temporarily disable
403 the loopback check for one cycle of startup/shutdown of the service.
404 We assume most folks do not start/stop without a reboot so this
405 will be adequate in most cases.
407 * Fix security hole in afslogon.dll which allowed passwords to be
408 sent in clear text to the KDC in a misformed principal name.
410 * Fix cm_GetCell() to properly handle expired dns entries
413 * If Freelance mode is active and the afs_freelance.ini
414 file does not exist, do not create an empty file.
415 Instead create a file containing ro and rw mountpoints
416 to the default cell using the standard conventions.
418 * Modify the Freelance support to handle the ability
419 to create rw mount points in the fake root.afs volume.
421 * Changed the RPC mechanism used for token setting from
422 named pipes to local. Use of named pipes can be restored
423 by setting the environment variable AFS_RPC_PROTSEQ to
426 Named pipes were required when a Windows 9x system was
427 using a NT system in gateway mode which is incompatible
428 with our use of local loopback adapters.
430 * In afscreds.exe, if a username of the form user@REALM is
431 specified and no password is specified, do not perform a
432 kinit operation. Only perform the aklog functionality.
434 * Add a new registry value which allows the number of processors
435 on which afsd_service.exe executes to be restricted. Valid
436 values are 1..numOfProcessors
438 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
442 * A second MSI based installer option is now available.
444 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
445 request tickets for user/instance@REALM instead of just user@REALM
447 * Modify the Power Management Notify routine to wait for the Hard Dead
448 timeout period instead of a fixed 19 seconds. With the longer timeout
449 periods Hibernation and Standby could never succeed when network
450 connectivity is not available.
452 * The following fs.exe commands are now restricted to Administrator:
453 - checkservers with a non-zero timer value
456 - sysname with a new sysname list
465 setting the default sysname for a machine should be done via the
466 registry and not via "fs sysname".
468 * NSIS installer adds options to install Debugging Symbols
469 and the Microsoft Loopback Adapter; the user is now also
470 given the ability to select the afscreds.exe startup options.
472 * Build system modified to generate symbols for FREE (aka RELEASE)
473 builds as well as CHECKED (aka DEBUG) builds
475 * Sites which have a volume ID of 0x20000001 assigned to their
476 root.cell volumes have been experiencing problems with accessing
477 the root.cell volume of their cell when Freelance mode has been
478 active. This was because 0x20000001 was assigned to the fake
479 root.afs volume created by freelance. The fake volume id is
480 now set to 0x00000001 to prevent conflicts.
482 * The timeout logic in the AFS Client Service has been wrong
483 for sometime. It is based on two different assumptions.
484 First, the SMB client timeout is a fix value as was the case
485 with OS/2 Lan Manager. This assumption is incorrect. The
486 SMB timeout in Windows is a dynamic value computed based upon
487 a fixed minimum timeout to which is added time based upon the
488 size of the request and the performance characteristics of
489 the connection. Second, it is the responsibility of the
490 SMB Server to enforce the timeout requirements of the client.
491 This is untrue. The SMB Server cannot be expected to know
492 the requirements of the client. More importantly, if the
493 SMB server uses the SMB client timeout as a value to restrict
494 its behavior as an RX client, the performance characteristics
495 of the local SMB session would be used to prematurely terminate
496 WAN connections with significantly different performance
499 The timeout logic has therefore been modified in the following
501 . the Lan Manager Workstation (SMB) Session Timeout is used only
502 as a basis for configuring the Connection Dead Timeout
503 and Hard Dead Timeout values. The Connection Dead Timeout
504 must be at least 15 seconds longer than the SMB Timeout
505 and the Hard Dead Timeout must be at least double the
506 Connection Dead Timeout.
507 . New registry entries have been added to allow the Connection
508 Dead Timeout and Hard Dead Timeout values independent of the
509 Lan Manager Workstation Session Timeout
510 . The test to enforce the SMB Client Timeout has been removed.
512 One of the side-effects of removing the enforcement of the SMB
513 Client Timeout is that regardless of whether or not the SMB client
514 is available to receive the response (and how would the SMB server
515 know) the RX protocol response can be used to update the AFS
516 Client Service state for ready access by future SMB client
519 This should be the end of the "Server paused or restarting messages"
521 * Add support for arbitrary UNC paths to the pioctl() support.
522 This enables the fs commands as well as the AFS Shell Extension
523 to work correctly when UNC paths are being used.
525 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
526 DNS if the cell configuration cannot be determined via CellServDB
528 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
529 are ever set more than once at a time
531 * Fix the management of lists of cm_cell_t structures when using
532 DNS to lookup cell information. The previous code would fail to
533 reuse the same cellID for a cell if DNS was used more than once
534 for a given cell name. When the ttl expired, a single cm_cell_t
535 could be inserted into the cm_allCellsp list more than once
536 producing a loop. In addition, the vlServerp list belonging to
537 the cell was not freed resulting in improper refCounting of the
540 * Add DNS support to cm_IoctlNewCell() which previous only examined
543 * Add cm_FreeServer() function and call it from cm_FreeServerList()
544 to properly garbage collect cm_server_t objects
546 * Add numVCs variable to smb.c to track the number of smb_vc_t
547 objects created and use it to initialize the vcID field which
548 previously was set to 0 in all objects resulting in FindByID
551 * Fixed DNS lookups to work consistently throughout the OpenAFS
552 product instead of just from within the afsd_service.exe
554 * Added a runtime check to ensure that AFS Client Service SMB
555 Server is accepting connections before attempting to mount
558 * Read IP addresses for volume servers out of the CellServDB
559 file if gethostbyname() on the hostname fails.
561 * Fix getcellconfig() to populate both the Hostnames as well
562 as IP addresses when loading cell data via DNS
564 * Increase the Connection Dead Time to 50 from 20 seconds
565 Increase the Hard Dead Time to 120 from 40 seconds
566 (matches the Unix values)
568 * Fixed an assertion validating the number of allocated NCBs
570 * Fixed the build environment to consistently build for
571 Windows 2000 and above. (APPVER = 5.0)
573 * Fixed rx_debug to properly validate the receipt in incoming
574 data with select() and recvfrom(). Do not copy data out of
575 the socket buffer unless success is indicated.
578 * afsd_service.exe will now display a message box to the
579 desktop when it terminates due to an IP Address Change.
581 * installer no longer deletes AFS Server configuration data
584 * installer generates a warning dialog if the RPC service
585 is not properly configured
587 * installer compressed with lzma instead of bzip2
589 * afsd_service.exe shutdown crash solved once and for all
591 * reference counting of smb_vc_t data structures improved
593 * name space collision of smb_fid_t event objects corrected
595 * the output of "fs memdump" is now written to
596 %WINDIR%\TEMP\afsd_alloc.log
598 * the file TaAfsApp_1033.dll is now properly installed allowing
599 the User Manager to start
601 * a new algorithm is used for computing filename pattern matches
603 * afscreds.exe now accepts user names containing instance
606 * Fix the Directory Name Lookup Cache to be case-sensitive.
607 This is crucial in environments in which a Windows client
608 is accessing a directory with more than one filename that
609 differs only by case. If the directory contains "FOO"
610 and "Foo". You want "DEL Foo" to delete the correct one.
611 We still have a problem in that "DEL foo" will delete a
612 random filename. This will be addressed in a future release.
614 * Fix afscreds.exe -M option (renewMaps) to work when High
615 Security mode is off. Also, remember to disable the ActiveMap
616 flag in afsdsbmt.ini when a drive mapping is removed.
618 * Updates to NSIS installer script. AFS Server configuration
619 data will not be destroyed on un-install or re-install.
620 Use a better compression algorithm.
622 * afslogon.dll now uses KFW to obtain tokens when available
624 * afslogon.dll when given an all uppercase username will
625 attempt to authenticate with both the uppercase name
626 and an all lowercase variation
628 * DST modification removed. The fix appears to make things
629 worse after a reboot of the machine.
631 * fs.exe: added "cscpolicy" which is used to
632 change client side caching policy for AFS shares
634 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
635 [-documents] [-disable] [-help]
637 * Several uninitialized variables have been initialized
639 * It is now possible to obtain tokens using cross realm
640 Kerberos within afscreds.exe:
642 user: jaltman@ATHENA.MIT.EDU
644 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
645 will will in turn be used to obtain afs@DEMENTIA.ORG.
646 The resulting token will be stored with the display name
647 jaltman@ATHENA.MIT.EDU@dementia.org
649 * aklog.exe has been added to the client
651 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
652 [[-p | -path] pathname]
656 -d gives debugging information.
657 krb_realm is the kerberos realm of a cell.
658 pathname is the name of a directory to which you wish to authenticate.
659 -noprdb means don't try to determine AFS ID.
660 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
661 (default is Kerberos V)
662 No commandline arguments means authenticate to the local cell.
665 * All of the resource files have been restructured to adhere to
666 a set of rules IBM implemented for loading string resources.
667 These rules had either been forgotten or were not discovered
668 by folks working on the OpenAFS sources. The end result was
669 memory corruption. This is primary item which was preventing
670 the AFS Server from working.
672 * Increased the size of the maximum ticket size stored in a token
673 from 344 bytes to 12,000. Increased the buffers used to convey
674 messages between the pioctl() caller and the SMB Server from
675 1000 bytes to 12,512. The code appeared to have been writing
676 above the top of the stack by quite a few number of bytes.
677 (The increased ticket size is necessary for the next item.)
679 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
680 Instead the raw Kerberos 5 ticket is used in its entirety. This
681 is extremely important as it allows us to use pure Kerberos 5 KDCs
682 as the source of the AFS authentication. The use of up to 12,000 byte
683 tickets will allow tickets produced by all versions of Microsoft
684 Active Directory to be used.
685 - create a user account.
686 - designate it DES only
688 - specify its UPN to be "afs@realm"
689 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
691 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
692 is special when using long file names. (you must use "*.*" and not "*")
693 Instead only enforce it when performing 8dot3 searches.
695 * Fixed the DST problem with creation times being set one hour ahead
697 * Fixed the problem when using \\afs\cell-alias. For example,
698 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
699 for the alias name; instead simply expand the name. One of the
700 symptoms of this problem was a loss of acquired tokens.
702 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
703 of strings. (Only English strings provided.)
705 * Fixed the installer to properly replace in use files.
707 * Fixed the build system to cleanup generated component version files
709 * The release build compiled with MSVC 6.0 compiler to avoid the
710 afsd_service.exe shutdown crash. This does not solve the problem
711 but simply avoids it for the time being.
715 * fix afslogon.dll to not corrupt memory when High Security mode
718 * fix afsd_service.exe to not attempt to restore the stack when
719 an exception occurs. (not safe in multi-threaded programs)
721 * fix uninstaller to properly remove the CRT and MFC DLLs
723 * remove a Message Box from afscreds.exe when getcellconfig()
724 fails on a kerberos realm which is not a cell
726 The following is a list of changes to the OpenAFS for Window client
729 * "fs setserverprefs" will leave afsd service deadlocked
731 * "vos listaddrs" will core dump
733 * installer sets the appropriate keys to support Integrated Logon
735 * installer disables the "Find Lana by Name" functionality as it
736 was causing headaches for many users
738 * fix the intermittent crash of the power management thread when
739 shutting down the AFS Client Service
741 * optimizes the obtain drive mount list functionality which is
742 executed every time the mount tab in afscreds.exe and afs_config.exe
743 are refreshed. (this happens a lot)
745 * fix the service shutdown logic. add the STOP_PENDING state
746 and do not accept additional service events after we declare
749 The following is a list of changes to the OpenAFS for Window client
752 * flexelint was run against the source tree and hundreds (perhaps
753 thousands) of corrections were applied to ensure prototypes
754 were in use; types were used consistently; variables were
755 initialized; unused variables were removed; etc.
757 * A wide variety of instrumentation was added including the
758 ability to produce a stack trace from within afsd_service.exe
761 * Dynamic configuration of the RDRtimeout value based upon the
762 LanMan Workstation Session Timeout
764 * The mount root no longer needs to be called "/afs". This
765 is now set by a registry value "MountRoot" within the key
766 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
768 * The cell list is now only read out of afsdcell.ini when the
769 file changes instead of each time a cell is resolved.
771 * Thread synchronization was added to cm_server.c and ktc_nt.c
773 * All calls to GlobalAlloc()/GlobalFree() were replaced with
774 calloc()/free(). The Global functions were needed on Windows 3.x
775 but have caused a variety of problems on the Win32 platforms.
776 Avoiding them is highly recommended by several Microsoft
777 Knowledgebase articles
779 * Support for Symbolic Links added to the AFS Shell Extension
781 * Added a registry value "OverlayEnabled" to determine if
782 Shell Extension Overlays should be enabled.
783 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
785 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
786 separate trees for checked and free builds. Build system supports
787 a custom directory src\WINNT\extra which can be used as a grafting
788 location of organization specific additions to the build tree.
790 * New installer built using NSIS 2.0.
792 * Named all kernel objects in order to allow them to be monitored
793 with tools such as SysInternals' ProcExp.exe.
795 * Introduced new EventLog framework for AFSD
797 * Introduced Power Management interface to AFSD for Standby and
798 Hibernate modes to allow cache to be flushed prior to network
801 * Utilize Win32 DNSQuery API instead of internal routines. This
802 allows DNS SRV queries to be sent to all current domain name
803 servers. Not just one specified in an INI file. DNS is now
806 * "NetbiosName" registry value may be used to specify a fixed
807 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
808 when the loopback adapter is in use. If you need to use the
809 old notation with a loopback adapter installed specify a registry
812 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
814 * Refactor all modules which depend on LAN Adapter and NetbiosName
815 determination in a new library: lanahelper.lib. This allows for
816 consistent behavior throughout the product.
818 * Move the afsd.log and afsd_init.log files to the directory specified
819 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
820 for services. Added the Date to the log entries.
822 * New registry value "RxMaxMTU" used to limit the size of the RX
823 packets sent by the AFS Client Service to the Server. In order
824 to enable OpenAFS to work across the Cisco IPSec VPN the packet
825 size must be restricted to 1264 or smaller. The latest NSIS
826 installer sets a value of 1260 by default.
828 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
829 packets. This is not needed in order to work across the Cisco
830 VPN but might be needed for other network environments. This
831 value is not set by the NSIS installer.
833 * New registry value "HideDotFiles" is used to apply the Hidden
834 attribute to files whose names begin with a '.'. This value
835 is set by the NSIS installer.
837 * New registry value "MaxMpxRequests" allows the maximum number
838 of multiplexed sessions to be configured at run time. This
839 value is not set by the NSIS installer. The default value is
842 * New registry value "MaxVCPerServer" allows the maxmimum number
843 of VCs per server to be configured at run time. This value is
844 not set by the NSIS installer. The default value is 100.
846 * New registry value "AllSubmount" allows the "all" submount to
847 be disabled by setting its value to 0x00.
849 * Allow cells names to be valid mount points
850 \\<netbiosName>\<cellname>
852 * Store the active state of drive mappings in order for afscreds.exe
853 to restore them upon startup
855 * Add exception handling to generate a Stack Trace to the afsd_init.log
856 file if one happens to occur.
858 * Add lots of logging to help detect the cause of invalid SMB packets
860 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
861 conversion of Kerberos 5 "afs" service tickets. Supports auto-
862 renewal of expiring tokens as long as afscreds.exe is running.
864 * New afscreds.exe command line options:
866 -M = renew drive maps
867 -N = ip address change detection
870 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
871 determines whether or not MIT Kerberos for Windows should be used
872 to obtain tokens via Kerberos 5 tickets.
874 * New registry value "AfscredsShortcutParams" in
875 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
876 determines the command line parameters to be specified when "fixing"
877 the AFS Shortcut in the user's startup folder.
879 * The "ShowTrayIcon" registry value has been moved from
880 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
881 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
883 * The <cell name> registry values used to store the token expiration
884 reminders have been moved from
885 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
886 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
888 * Obtain the Logon User Name from the Explorer key when available
890 * new text document doc\txt\winnotes\registry.txt lists all registry
891 values used by OpenAFS (excluding the AFS Server)
893 * BUG: rx_securityClass objects were not properly reference
894 counted and were never freed.
896 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
897 would be generated. The existence of a server does not imply
898 that it is not down. If all of the servers for a cell are down
899 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
902 * BUG: the directory name lookup cache failed to free the entries
903 in the cache when the name cache entries cycled. The entries
904 in the cache would become dereferenced without being freed.
906 * BUG: fs setserverprefs could be executed without Administrator
909 * BUG: the number of allocated NCB objects (100) exceeded the number
910 which could actually be waited upon by the kernel (64). Any objects
911 which were utilized above the limit could never have event completions
914 * BUG: smb_username_t objects were not being reference counted and
915 were not properly freed.
917 * BUG: smb_tid_t objects could under unusual circumstances be freed
918 before they were no longer referenced.
920 * BUG: smb_fid_t object pointer were frequently used even when
921 their value could be NULL. They were not properly released and
922 therefore they were never freed.
924 * BUG: smb_packet_t data structures were not completely initialized
927 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
928 Denied" because that causes the Explorer Shell to try again until
929 access is obtained. Instead return "Remote Resources" which allows
930 the shell to move on and treat the error as transient.
932 * BUG: when initializing the NCBreturns structure, separate Event objects
933 were created for each NCB although a single Event object was supposed
936 * BUG: smb_dirSearch_t objects were not being properly referenced counted
939 * BUG: smb_tran2Packet_t objects were not being properly referenced
942 * BUG: directory path creation did not handle the case of multiple
943 directories requiring creation in one attempt
945 * BUG: SMB requests which required an Extended Response were ignored.
946 This prevented some files from being written to AFS volumes.
948 * BUG: character strings were being freed even after they were
949 inserted into in use data structures
951 * BUG: inconsistent usernames were used when High Security mode was
952 enabled. (there is still much to do in this area)
954 * BUG: pioctl() calls which require out of band RPC operations were
955 susceptible to race conditions when performed by multiple processes
957 * BUG: memory allocation and deallocation crossed instances of the
958 C Runtime Library producing memory leakage and corruption in
959 afscreds and the client configurator.
