3 * Support has been added for multi-homed servers
6 * Added a new registry value, "StoreAnsiFilenames", which can be used
7 to force the use of ANSI character sets instead of OEM Code Pages.
8 This feature is useful when users require the ability to create
9 filenames with 8-bit characters and need to access the files from
10 both Latin-1 based Unix systems as well as from Windows.
12 Activation of this feature will prevent access to files stored with
15 * Shutdown all SMB threads in a synchronized manner when stopping the
18 * There is currently a maximum cache size of 1.3GB. The limit is imposed
19 by the largest contiguous block of unused memory within the 2GB process
20 space which can be assigned to the memory mapped file. Unfortunately,
21 when the executable digital signature verification code is activated
22 Windows sees fit to further segment the process memory which in turn
23 reduces the size of the maximum cache file to less then 800MB. If
24 larger cache sizes are desired, a new registry value should be set:
26 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
28 Setting this value will disable the runtime verification of digital
29 signatures on afsd_service.exe and the afs dlls which it loads. It
30 will not disable the the version number check on those same files.
31 The signature verification is not a security messure and is only meant
32 to enhance the ability to afsd_service.exe to detect potential
33 destablizing mixtures of DLLs from incompatible distributions.
35 Added code to auto-disable the signature verification check if
36 the desired cache size is greater then 700MB.
38 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
39 used to verify the validity of the afsd_service.exe binary
40 as well as each of the AFS DLLs loaded by the service. Not only
41 must the digital signature be valid but the signatures of the
42 DLL must be signed by the same entity as the service.
44 * Implement new functions: cm_freelanceMountPointExists and
45 cm_freelanceSymlinkExists. Use them along with other validity
46 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
47 ensure that name collisions do not occur and that empty strings
48 are not valid file names.
50 A symlink may not have a name which would resolve to a valid
51 cell name. Doing so would prevent access to the cell.
53 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
54 re-initialization code. The reference counts of the fake root.afs
55 volume scache object(s) would become invalid when the mount point
56 or symlink lists were altered.
58 * Add registry entries to provide mappings from the afsdsbmt.ini
59 to the new locations for applications which count on the use
60 of the old Profile file APIs. These apps are likely to fail
61 if the user does not have administrator privileges and the
62 registry is locked down.
64 * The afs_config.exe submounts dialog had two errors.
65 First, attempts to remove entries failed because the registry
66 key was being opened without KEY_WRITE privileges.
67 Second, when editing a submount entry, changing the name
68 would add a new key and leave the original one in place.
69 Now the original submount will be removed if its name is
72 * In recent months there have been several incidents in which
73 users have experienced problems starting or accessing
74 afsd_service.exe and after significant effort has been spent
75 it has turned out that they have two versions of AFS on the
76 machine or an inconsistent set of DLLs.
78 Code has now been added to afsd_service.exe which will walk
79 the list of modules loaded by afsd_service.exe and validate
80 that the version of the AFS DLLs matches the version of the
81 afsd_service.exe executable. If they do not match the service
84 * When Freelance mode is enabled and there is no registry
85 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
86 will attempt to import the afs_freelance.ini file contents.
87 If the file does not exist, it was creating a dummy file
88 with a r/o and r/w entry for the default cell and then
89 importing those values.
91 This process has been changed. The temporary file is no
92 longer created. Also, both the OpenAFS Client install
93 directory as well as %WINDIR% are checked for previous
94 afs_freelance.ini files.
96 * Added support for VL_GetEntryByNameN(). Still need to add
97 support for VL_GetEntryByNameU() for multi-homed support.
99 * Fix a deadlock situation in afscreds.exe when canceling an
100 auto-generated Obtain Tokens dialog
103 * Fix the locking of objects during Directory Searches in the
104 SMB/CIFS server. The failure to properly lock the reference
105 counts was resulting in the premature freeing of smb_dirSearch_t
106 objects while they were still in use by the SMB/CIFS client.
107 This does not solve the "Invalid Handle" problem.
109 * Fix Find Cell By Name pioctl call to return a valid cell
110 name for the Freelance fake root.afs volume.
111 "Freelance.Local.Root".
113 * Fix the Explorer Shell Extension Symlinks->Add operation.
114 The dialog template was missing and the link destination
115 string was too short.
117 * Add support for symlinks to Freelance root.afs volume
118 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
119 <number> = "<linkname>:<relative-path>."
120 Use symlink.exe to create, list, or remove
122 * Remove the fallback to the use of KFW's KRB4 library when obtaining
123 tokens. We never obtain KRB4 tickets.
125 * Fix AFS Client Configuration Control Panel to support new SysName
127 * Fix a bug in afsd_service.exe which could result in the SysName
128 not being read from the registry.
131 * Add code to block the issuance of AFS tokens by aklog.exe or
132 afscreds.exe when the Kerberos 5 principal name contains a dot.
134 * Modify the IsAdmin() function to always treat the local SYSTEM
135 account as an AFS client administrator. Affects fs.exe and
138 * Modify the internal handling of Quota Exceeded errors
140 * Upgrade all reference count fields in the Windows cache manager
141 and the osi library to use unsigned long instead of signed short.
142 A similar fix has been applied to the afs rpc (rx) library.
144 * fix the Windows cache manager to prevent it from replacing the
145 rx_connection object associated with the cm_conn_t object on each
146 and every operation if "fs crypt" was set. This explains the
147 dramatic performance difference when crypt is used vs clear.
148 The problem: 'cryptall', a boolean flag indicating whether or not
149 "fs crypt" is set, was being compared to the rx_connection
150 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
151 1 != 2 and therefore the rx_connection was always destroyed
152 and replaced on each and every operation.
154 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
155 It is not safe for the cm_conn_t object to not be locked because
156 rx_DestroyConnection might be called from another thread if:
157 - the user's tokens have changed or expired
158 - the crypt mode has changed
160 This fix appears to have also taken care of the problems associated
161 with Overlapped Writes resulting in Delayed Write errors.
163 * fix NSIS installer's AdminGroup.exe to properly create and
164 remove groups when given -create or -remove. The string comparison
167 * fs sysname now accepts a list of sysname values
169 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
170 DWORD which when set to a non-zero value will cause error message
171 text to be output to stderr from the pioctl() routine. Useful in
172 debugging failures of fs.exe, tokens.exe, etc.
174 * added a test to the power management code to only perform a
175 flush operation if there is at least one network adapter which
176 is not a loopback adapter.
178 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
179 "EnableKFW". This value will not be read if the key
180 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
181 value under that key does not.
183 * provide mechanisms to force the use of krb524d for Kerberos 5
184 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
185 there is a new registry value "Use524" and for aklog.exe a new
186 command line parameter "-m".
188 * Fix the pattern matching algorithm to properly match patterns
191 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
192 which is used by both the original function and the new
193 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
194 creation of HardLinks in addition to Renaming. smb_Link()
195 is a new function which creates HardLinks via cm_Link().
196 cm_Link() is a new vnodeops function which creates links
199 smb_ReceiveNTRename() does not support the File Copy and
200 Move Cluster Information operations described in its interface.
201 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
203 * When opening files via symlinks, we should follow the symlinks
204 until we reach the actual file stat cache entry. The stat cache
205 entry of the file should then be stored in the FID instead of
206 stat scache entry of the symlink.
208 * return bad operation errors for all unimplemented functions
209 even if we do not know the functions exist.
211 * Log bad packets and unknown operation packets to the trace log
213 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
216 * Update list of known CIFS operations to include all those listed
217 in CIFS-TR-1p00_FINAL.pdf.
219 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
220 to support the REG_EXPAND_SZ type.
223 * A new Windows authorization group "AFS Client Admins" is now
224 created and populated with the members of the "Administrators"
225 group. The group is used to determine which accounts on the
226 machine may be used to modify the AFS Client Configuration via
227 the UI and command line tools. afs_config.exe, fs.exe,
229 * Modify the WinLogon Logoff Event Handler to query NT4 domain
230 controllers for the remote profile path if Active Directory
231 services are not available.
233 * Fix aklog.exe to not add the AFS ID to the username
235 * PTS registration of new users to foreign cells has been added to
238 * The cm_Daemon thread is used to perform checks for
239 down servers, up servers, volumes, callback expirations,
240 lock maintenance and token expiration. Due to a gaff in
241 larger integer division the thread never performed any
242 work. Instead the current time computation would always
243 be less then the trigger times. This had an adverse affect
244 on the client's ability to maintain communication with servers,
245 keep volumes up to date, and flush user tokens and acls
246 when they have expired. This was broken when the 1.3 branch
247 was modified to support VC7 which no longer included
250 * An initialization problem with the Freelance code was
251 detected while fixing the callbackRequest. The cm_rootSCachep
252 object is obtained during afsd_InitDaemons() but the callback
253 information is incomplete. The callback information will not
254 be obtained until cm_MergeStatus is called from within
255 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
256 test for the conditions under which the callback information
259 * Reports have been filed indicating that callbacks were
260 being lost. An examination of the code indicated that the
261 cm_server_t objects were not being properly reference
262 counted by the cm_scache_t and cm_callbackRequest_t objects.
263 In particular, the cm_server_t objects may have been freed
264 from beneath the cm_conn_t objects.
266 All of the reference counting is now done via the functions:
271 this improves the ability to track the referrals.
273 Each cm_BeginCallbackGranting Call now allocates a reference
274 to the cm_server_t. The cm_EndCallbackGrantingCall either
275 frees the reference or transfers it to the cm_scache_t
276 cbServerp field. These are then appropriately tracked
277 through the cm_Analyze call.
279 * Ensure that the dnlc hash table is the same size as the
280 dir name hash table (as per original author's note).
281 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
282 for compatibility with 64-bit systems.
284 * fix smb_ApplyV3DirListPatches to properly apply the hidden
285 attribute to dotfiles when the infoLevel < 0x101 and
286 cm_SyncOp has failed.
288 * Fix the Freelance registry initialization code. There
289 was a possibility that some systems could end up with
290 garbage in the registry during a clean install.
293 * file and directory names beginning with "." will now be given the
294 hidden attribute when the volume access is anonymous. this matches
295 the behavior when the volume access is via an authenticated user.
297 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
298 key. When a change occurs mark the root.afs data as invalid and
299 for it to be reloaded on the next access. This allows administrators
300 to modify the mount point list without restarting the service.
302 The freelance client used to provide a fake modification time for
303 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
304 Added code to extract the last modification time of the Freelance
305 registry key and use that instead. The time now represents the
306 most recent mount point change.
308 * PTS registration of new users to foreign cells has been added to
311 * Additional Cache Control and Credential Manager options have been
312 added to the WiX installer. See deployment guide for details.
314 * The CachePath setting is now optionally a REG_EXPAND_SZ type
316 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
319 * The loopback installation code may have had a problem updating the
320 %ETC%\HOSTS file which could have resulted in a premature failure.
321 Work around code has been added for the case where the file cannot
324 * The default max chunksize was increased from 15 (32K) to 17 (128K)
325 because Windows sends 64K blocks when using overlapped writes.
327 * The default number of server threads was increased from 4 to 25 to
328 better handle overlapped writes.
330 * The "AfscredsShortcutParams" registry value was not being properly
331 loaded by afscreds.exe. Therefore, the default value was always being
332 used instead of the value set by the installer.
334 * Windows XP provides downgrade attack detection to prevent an attacker
335 from being able to force the use of NTLM simply by disrupting
336 communication with the KDC. This attack cannot exist between the
337 Windows CIFS client and the AFS Client Service. Therefore, when a
338 downgrade has been detected the afs pioctl library will force the
339 establishment of a new CIFS connection using NTLM.
341 * A locking error was discovered surrounding all references to volume
342 server lists within the cm_cell.c source file.
344 * The logged into Windows username was incorrect on Terminal Server
347 * A new registry value "NonPersistentCaching" was added to the service
348 parameters key. When set to a non-zero value, the afs cache is stored
349 in the Windows paging file. There are two limitations to choosing
351 1. when persistent caching is implemented it won't work with
352 this flag set since there will be nothing to persist.
353 2. with this flag set the initial paging allocation cannot be
354 changed while the service is running
356 * An initialization bug was discovered in aklog.exe which affected users
357 who have a domain name for their afs servers which could not be mapped
361 * afs_config.exe now validates cell names against DNS in addition
362 to the CellServDB file.
364 * In order to allow the freelance client to connect to a volume with ID
365 equal to 1 on the default cell we changed the fake root.afs volume ID
366 once again. This time we choose 0xFFFFFFFF. In addition, we change
367 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
368 It will now be impossible for a volume ID to match that of another
369 cell unless the client is connected to 0xFFFFFFFD cells. That should
370 be enough room for growth.
372 * Fix "fs mkmount" command to work with UNC paths and when
373 started from non-AFS drives. It is now possible to create a mount
374 point in the freelance fake root.afs volume with the command
376 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
380 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
381 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
383 * The algorithm used to re-attempt access to the servers associated with
384 a volume has been altered to properly address the case in which all
385 servers have been marked down. The previous algorithm did not reset
386 the server's down flags so the servers were never actually retried.
387 This caused a problem with active volumes if the network connectivity
388 was lost as could be the case with a network cable removal, wireless
389 drop, or laptop hibernation. With the fix volume access is restored
390 almost instantenously when network connectivity becomes available.
392 * Support for SMB/CIFS browsing has been added to the AFS Client Service
393 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
394 listing of AFS submounts and freelance mount points. Support for
395 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
396 significantly enhances the behavior of AFS volumes within the Explorer
397 Shell. For instance, "AFS" now shows up as server in the Explorer
398 with each submount or freelance mount point visible as a share.
399 The right click menu in each folder now works with full functionality
400 on a consistent basis.
402 * The network provider can be configured to have different behavior
403 depending on the domain that the user logs into. These settings are
404 only relevant when using integrated login. A domain refers to an
405 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
406 local machine (i.e. local account logins). The domain name that is
407 used for selecting the domain would be the domain that is passed into
408 the NPLogonNotify function of the network provider. (see registry.txt
411 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
412 "Authentication Cell" which may be used to specify a default
413 authentication cell for afscreds.exe which is different from
414 the default cell for the AFS Client Service daemon.
416 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
417 afslogon.dll moved to %WINDIR%\System32\.
418 New registry entries added to register the dll for Winlogon events.
420 The logoff event will now force a call to ktc_ForgetAllTokens()
421 using the context of the user being logged off as long as the
422 user's profile is not loaded from within AFS. If the profile
423 was loaded from AFS we can't release the tokens since the Logoff
424 event is triggered prior to the profile being written back to
425 the its source location. This is now performed in an XP SP2
428 * Windows XP SP2 Internet Connection Firewall interoperability
431 * The %WINDIR%\afsdsbmt.ini contains four sections:
432 Submounts, Drive Mappings, Active Maps and CSC Policies.
433 The Submounts and CSC policies are now stored in the registry under
434 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
435 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
436 The Drive Mappings and Active Maps are stored in the registry under
437 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
438 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
440 There is no automatic migration of this data as it would be impossible
441 to consistently migrate data to user profiles which may not be active
442 when the machine is updated.
444 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
445 fake root.afs volume. For the same reasons as for the cellservdb file,
446 this information should not be in %WINDIR%. This information is now
447 kept under the registry key
448 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
450 The data from the afs_freelance.ini file will be automatically
451 migrated to the registry on first execution of afsd_service.exe
453 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
454 troublesome for several reasons. One, it is confusing for those who
455 expect the file to be named "CellServDB" instead of "afsdcell.ini".
456 Two, this file is not a Windows Profile formatted file. Three,
457 applications should not be reading or writing to %WINDIR%. It causes
458 problems for Windows Terminal Server.
460 The new location of CellServDB will be the OpenAFS Client install
461 directory which is by default C:\Program Files\OpenAFS\Client and can
462 be determined by querying the registry for
463 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
465 The existing afsdcell.ini will be migrated by the NSIS installer.
466 The Wix installer must still be updated to do the same.
468 * Change NSIS installer to use DNS by default; to remove Integrated Logon
469 High Security mode; and to add Terminal Services compatibility registry
470 entries to allow the OpenAFS tools to find the afsdcell.ini and other
471 configuration files in %WINDIR%.
473 * Add support for authenticated SMB connections. This will remove
474 the need for high security mode in most situations. Both NTLM
475 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
476 only NTLM can be used even though Kerberos is now supported. The
477 reason is that it is not possible to construct a service principal
478 which is unique to each individual machine.
480 SMB Extended Auth does not work on XP SP2 unless one of two registry
481 modifications are made:
483 (1) To disable the check for matching host names on loopback connections
484 set this key. This does not require a reboot:
486 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
487 "DisableLoopbackCheck"=dword:00000001
489 (2) To add the AFS SMB/CIFS service name to an approved list. This
490 does require a reboot:
492 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
493 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
495 afsd_service.exe will automatically add the current Netbios Name
496 to the BackConnectionHostNames list and then temporarily disable
497 the loopback check for one cycle of startup/shutdown of the service.
498 We assume most folks do not start/stop without a reboot so this
499 will be adequate in most cases.
501 * Fix security hole in afslogon.dll which allowed passwords to be
502 sent in clear text to the KDC in a misformed principal name.
504 * Fix cm_GetCell() to properly handle expired dns entries
507 * If Freelance mode is active and the afs_freelance.ini
508 file does not exist, do not create an empty file.
509 Instead create a file containing ro and rw mountpoints
510 to the default cell using the standard conventions.
512 * Modify the Freelance support to handle the ability
513 to create rw mount points in the fake root.afs volume.
515 * Changed the RPC mechanism used for token setting from
516 named pipes to local. Use of named pipes can be restored
517 by setting the environment variable AFS_RPC_PROTSEQ to
520 Named pipes were required when a Windows 9x system was
521 using a NT system in gateway mode which is incompatible
522 with our use of local loopback adapters.
524 * In afscreds.exe, if a username of the form user@REALM is
525 specified and no password is specified, do not perform a
526 kinit operation. Only perform the aklog functionality.
528 * Add a new registry value which allows the number of processors
529 on which afsd_service.exe executes to be restricted. Valid
530 values are 1..numOfProcessors
532 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
536 * A second MSI based installer option is now available.
538 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
539 request tickets for user/instance@REALM instead of just user@REALM
541 * Modify the Power Management Notify routine to wait for the Hard Dead
542 timeout period instead of a fixed 19 seconds. With the longer timeout
543 periods Hibernation and Standby could never succeed when network
544 connectivity is not available.
546 * The following fs.exe commands are now restricted to Administrator:
547 - checkservers with a non-zero timer value
550 - sysname with a new sysname list
559 setting the default sysname for a machine should be done via the
560 registry and not via "fs sysname".
562 * NSIS installer adds options to install Debugging Symbols
563 and the Microsoft Loopback Adapter; the user is now also
564 given the ability to select the afscreds.exe startup options.
566 * Build system modified to generate symbols for FREE (aka RELEASE)
567 builds as well as CHECKED (aka DEBUG) builds
569 * Sites which have a volume ID of 0x20000001 assigned to their
570 root.cell volumes have been experiencing problems with accessing
571 the root.cell volume of their cell when Freelance mode has been
572 active. This was because 0x20000001 was assigned to the fake
573 root.afs volume created by freelance. The fake volume id is
574 now set to 0x00000001 to prevent conflicts.
576 * The timeout logic in the AFS Client Service has been wrong
577 for sometime. It is based on two different assumptions.
578 First, the SMB client timeout is a fix value as was the case
579 with OS/2 Lan Manager. This assumption is incorrect. The
580 SMB timeout in Windows is a dynamic value computed based upon
581 a fixed minimum timeout to which is added time based upon the
582 size of the request and the performance characteristics of
583 the connection. Second, it is the responsibility of the
584 SMB Server to enforce the timeout requirements of the client.
585 This is untrue. The SMB Server cannot be expected to know
586 the requirements of the client. More importantly, if the
587 SMB server uses the SMB client timeout as a value to restrict
588 its behavior as an RX client, the performance characteristics
589 of the local SMB session would be used to prematurely terminate
590 WAN connections with significantly different performance
593 The timeout logic has therefore been modified in the following
595 . the Lan Manager Workstation (SMB) Session Timeout is used only
596 as a basis for configuring the Connection Dead Timeout
597 and Hard Dead Timeout values. The Connection Dead Timeout
598 must be at least 15 seconds longer than the SMB Timeout
599 and the Hard Dead Timeout must be at least double the
600 Connection Dead Timeout.
601 . New registry entries have been added to allow the Connection
602 Dead Timeout and Hard Dead Timeout values independent of the
603 Lan Manager Workstation Session Timeout
604 . The test to enforce the SMB Client Timeout has been removed.
606 One of the side-effects of removing the enforcement of the SMB
607 Client Timeout is that regardless of whether or not the SMB client
608 is available to receive the response (and how would the SMB server
609 know) the RX protocol response can be used to update the AFS
610 Client Service state for ready access by future SMB client
613 This should be the end of the "Server paused or restarting messages"
615 * Add support for arbitrary UNC paths to the pioctl() support.
616 This enables the fs commands as well as the AFS Shell Extension
617 to work correctly when UNC paths are being used.
619 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
620 DNS if the cell configuration cannot be determined via CellServDB
622 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
623 are ever set more than once at a time
625 * Fix the management of lists of cm_cell_t structures when using
626 DNS to lookup cell information. The previous code would fail to
627 reuse the same cellID for a cell if DNS was used more than once
628 for a given cell name. When the ttl expired, a single cm_cell_t
629 could be inserted into the cm_allCellsp list more than once
630 producing a loop. In addition, the vlServerp list belonging to
631 the cell was not freed resulting in improper refCounting of the
634 * Add DNS support to cm_IoctlNewCell() which previous only examined
637 * Add cm_FreeServer() function and call it from cm_FreeServerList()
638 to properly garbage collect cm_server_t objects
640 * Add numVCs variable to smb.c to track the number of smb_vc_t
641 objects created and use it to initialize the vcID field which
642 previously was set to 0 in all objects resulting in FindByID
645 * Fixed DNS lookups to work consistently throughout the OpenAFS
646 product instead of just from within the afsd_service.exe
648 * Added a runtime check to ensure that AFS Client Service SMB
649 Server is accepting connections before attempting to mount
652 * Read IP addresses for volume servers out of the CellServDB
653 file if gethostbyname() on the hostname fails.
655 * Fix getcellconfig() to populate both the Hostnames as well
656 as IP addresses when loading cell data via DNS
658 * Increase the Connection Dead Time to 50 from 20 seconds
659 Increase the Hard Dead Time to 120 from 40 seconds
660 (matches the Unix values)
662 * Fixed an assertion validating the number of allocated NCBs
664 * Fixed the build environment to consistently build for
665 Windows 2000 and above. (APPVER = 5.0)
667 * Fixed rx_debug to properly validate the receipt in incoming
668 data with select() and recvfrom(). Do not copy data out of
669 the socket buffer unless success is indicated.
672 * afsd_service.exe will now display a message box to the
673 desktop when it terminates due to an IP Address Change.
675 * installer no longer deletes AFS Server configuration data
678 * installer generates a warning dialog if the RPC service
679 is not properly configured
681 * installer compressed with lzma instead of bzip2
683 * afsd_service.exe shutdown crash solved once and for all
685 * reference counting of smb_vc_t data structures improved
687 * name space collision of smb_fid_t event objects corrected
689 * the output of "fs memdump" is now written to
690 %WINDIR%\TEMP\afsd_alloc.log
692 * the file TaAfsApp_1033.dll is now properly installed allowing
693 the User Manager to start
695 * a new algorithm is used for computing filename pattern matches
697 * afscreds.exe now accepts user names containing instance
700 * Fix the Directory Name Lookup Cache to be case-sensitive.
701 This is crucial in environments in which a Windows client
702 is accessing a directory with more than one filename that
703 differs only by case. If the directory contains "FOO"
704 and "Foo". You want "DEL Foo" to delete the correct one.
705 We still have a problem in that "DEL foo" will delete a
706 random filename. This will be addressed in a future release.
708 * Fix afscreds.exe -M option (renewMaps) to work when High
709 Security mode is off. Also, remember to disable the ActiveMap
710 flag in afsdsbmt.ini when a drive mapping is removed.
712 * Updates to NSIS installer script. AFS Server configuration
713 data will not be destroyed on un-install or re-install.
714 Use a better compression algorithm.
716 * afslogon.dll now uses KFW to obtain tokens when available
718 * afslogon.dll when given an all uppercase username will
719 attempt to authenticate with both the uppercase name
720 and an all lowercase variation
722 * DST modification removed. The fix appears to make things
723 worse after a reboot of the machine.
725 * fs.exe: added "cscpolicy" which is used to
726 change client side caching policy for AFS shares
728 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
729 [-documents] [-disable] [-help]
731 * Several uninitialized variables have been initialized
733 * It is now possible to obtain tokens using cross realm
734 Kerberos within afscreds.exe:
736 user: jaltman@ATHENA.MIT.EDU
738 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
739 will will in turn be used to obtain afs@DEMENTIA.ORG.
740 The resulting token will be stored with the display name
741 jaltman@ATHENA.MIT.EDU@dementia.org
743 * aklog.exe has been added to the client
745 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
746 [[-p | -path] pathname]
750 -d gives debugging information.
751 krb_realm is the kerberos realm of a cell.
752 pathname is the name of a directory to which you wish to authenticate.
753 -noprdb means don't try to determine AFS ID.
754 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
755 (default is Kerberos V)
756 No commandline arguments means authenticate to the local cell.
759 * All of the resource files have been restructured to adhere to
760 a set of rules IBM implemented for loading string resources.
761 These rules had either been forgotten or were not discovered
762 by folks working on the OpenAFS sources. The end result was
763 memory corruption. This is primary item which was preventing
764 the AFS Server from working.
766 * Increased the size of the maximum ticket size stored in a token
767 from 344 bytes to 12,000. Increased the buffers used to convey
768 messages between the pioctl() caller and the SMB Server from
769 1000 bytes to 12,512. The code appeared to have been writing
770 above the top of the stack by quite a few number of bytes.
771 (The increased ticket size is necessary for the next item.)
773 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
774 Instead the raw Kerberos 5 ticket is used in its entirety. This
775 is extremely important as it allows us to use pure Kerberos 5 KDCs
776 as the source of the AFS authentication. The use of up to 12,000 byte
777 tickets will allow tickets produced by all versions of Microsoft
778 Active Directory to be used.
779 - create a user account.
780 - designate it DES only
782 - specify its UPN to be "afs@realm"
783 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
785 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
786 is special when using long file names. (you must use "*.*" and not "*")
787 Instead only enforce it when performing 8dot3 searches.
789 * Fixed the DST problem with creation times being set one hour ahead
791 * Fixed the problem when using \\afs\cell-alias. For example,
792 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
793 for the alias name; instead simply expand the name. One of the
794 symptoms of this problem was a loss of acquired tokens.
796 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
797 of strings. (Only English strings provided.)
799 * Fixed the installer to properly replace in use files.
801 * Fixed the build system to cleanup generated component version files
803 * The release build compiled with MSVC 6.0 compiler to avoid the
804 afsd_service.exe shutdown crash. This does not solve the problem
805 but simply avoids it for the time being.
809 * fix afslogon.dll to not corrupt memory when High Security mode
812 * fix afsd_service.exe to not attempt to restore the stack when
813 an exception occurs. (not safe in multi-threaded programs)
815 * fix uninstaller to properly remove the CRT and MFC DLLs
817 * remove a Message Box from afscreds.exe when getcellconfig()
818 fails on a kerberos realm which is not a cell
820 The following is a list of changes to the OpenAFS for Window client
823 * "fs setserverprefs" will leave afsd service deadlocked
825 * "vos listaddrs" will core dump
827 * installer sets the appropriate keys to support Integrated Logon
829 * installer disables the "Find Lana by Name" functionality as it
830 was causing headaches for many users
832 * fix the intermittent crash of the power management thread when
833 shutting down the AFS Client Service
835 * optimizes the obtain drive mount list functionality which is
836 executed every time the mount tab in afscreds.exe and afs_config.exe
837 are refreshed. (this happens a lot)
839 * fix the service shutdown logic. add the STOP_PENDING state
840 and do not accept additional service events after we declare
843 The following is a list of changes to the OpenAFS for Window client
846 * flexelint was run against the source tree and hundreds (perhaps
847 thousands) of corrections were applied to ensure prototypes
848 were in use; types were used consistently; variables were
849 initialized; unused variables were removed; etc.
851 * A wide variety of instrumentation was added including the
852 ability to produce a stack trace from within afsd_service.exe
855 * Dynamic configuration of the RDRtimeout value based upon the
856 LanMan Workstation Session Timeout
858 * The mount root no longer needs to be called "/afs". This
859 is now set by a registry value "MountRoot" within the key
860 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
862 * The cell list is now only read out of afsdcell.ini when the
863 file changes instead of each time a cell is resolved.
865 * Thread synchronization was added to cm_server.c and ktc_nt.c
867 * All calls to GlobalAlloc()/GlobalFree() were replaced with
868 calloc()/free(). The Global functions were needed on Windows 3.x
869 but have caused a variety of problems on the Win32 platforms.
870 Avoiding them is highly recommended by several Microsoft
871 Knowledgebase articles
873 * Support for Symbolic Links added to the AFS Shell Extension
875 * Added a registry value "OverlayEnabled" to determine if
876 Shell Extension Overlays should be enabled.
877 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
879 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
880 separate trees for checked and free builds. Build system supports
881 a custom directory src\WINNT\extra which can be used as a grafting
882 location of organization specific additions to the build tree.
884 * New installer built using NSIS 2.0.
886 * Named all kernel objects in order to allow them to be monitored
887 with tools such as SysInternals' ProcExp.exe.
889 * Introduced new EventLog framework for AFSD
891 * Introduced Power Management interface to AFSD for Standby and
892 Hibernate modes to allow cache to be flushed prior to network
895 * Utilize Win32 DNSQuery API instead of internal routines. This
896 allows DNS SRV queries to be sent to all current domain name
897 servers. Not just one specified in an INI file. DNS is now
900 * "NetbiosName" registry value may be used to specify a fixed
901 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
902 when the loopback adapter is in use. If you need to use the
903 old notation with a loopback adapter installed specify a registry
906 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
908 * Refactor all modules which depend on LAN Adapter and NetbiosName
909 determination in a new library: lanahelper.lib. This allows for
910 consistent behavior throughout the product.
912 * Move the afsd.log and afsd_init.log files to the directory specified
913 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
914 for services. Added the Date to the log entries.
916 * New registry value "RxMaxMTU" used to limit the size of the RX
917 packets sent by the AFS Client Service to the Server. In order
918 to enable OpenAFS to work across the Cisco IPSec VPN the packet
919 size must be restricted to 1264 or smaller. The latest NSIS
920 installer sets a value of 1260 by default.
922 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
923 packets. This is not needed in order to work across the Cisco
924 VPN but might be needed for other network environments. This
925 value is not set by the NSIS installer.
927 * New registry value "HideDotFiles" is used to apply the Hidden
928 attribute to files whose names begin with a '.'. This value
929 is set by the NSIS installer.
931 * New registry value "MaxMpxRequests" allows the maximum number
932 of multiplexed sessions to be configured at run time. This
933 value is not set by the NSIS installer. The default value is
936 * New registry value "MaxVCPerServer" allows the maxmimum number
937 of VCs per server to be configured at run time. This value is
938 not set by the NSIS installer. The default value is 100.
940 * New registry value "AllSubmount" allows the "all" submount to
941 be disabled by setting its value to 0x00.
943 * Allow cells names to be valid mount points
944 \\<netbiosName>\<cellname>
946 * Store the active state of drive mappings in order for afscreds.exe
947 to restore them upon startup
949 * Add exception handling to generate a Stack Trace to the afsd_init.log
950 file if one happens to occur.
952 * Add lots of logging to help detect the cause of invalid SMB packets
954 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
955 conversion of Kerberos 5 "afs" service tickets. Supports auto-
956 renewal of expiring tokens as long as afscreds.exe is running.
958 * New afscreds.exe command line options:
960 -M = renew drive maps
961 -N = ip address change detection
964 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
965 determines whether or not MIT Kerberos for Windows should be used
966 to obtain tokens via Kerberos 5 tickets.
968 * New registry value "AfscredsShortcutParams" in
969 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
970 determines the command line parameters to be specified when "fixing"
971 the AFS Shortcut in the user's startup folder.
973 * The "ShowTrayIcon" registry value has been moved from
974 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
975 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
977 * The <cell name> registry values used to store the token expiration
978 reminders have been moved from
979 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
980 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
982 * Obtain the Logon User Name from the Explorer key when available
984 * new text document doc\txt\winnotes\registry.txt lists all registry
985 values used by OpenAFS (excluding the AFS Server)
987 * BUG: rx_securityClass objects were not properly reference
988 counted and were never freed.
990 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
991 would be generated. The existence of a server does not imply
992 that it is not down. If all of the servers for a cell are down
993 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
996 * BUG: the directory name lookup cache failed to free the entries
997 in the cache when the name cache entries cycled. The entries
998 in the cache would become dereferenced without being freed.
1000 * BUG: fs setserverprefs could be executed without Administrator
1003 * BUG: the number of allocated NCB objects (100) exceeded the number
1004 which could actually be waited upon by the kernel (64). Any objects
1005 which were utilized above the limit could never have event completions
1008 * BUG: smb_username_t objects were not being reference counted and
1009 were not properly freed.
1011 * BUG: smb_tid_t objects could under unusual circumstances be freed
1012 before they were no longer referenced.
1014 * BUG: smb_fid_t object pointer were frequently used even when
1015 their value could be NULL. They were not properly released and
1016 therefore they were never freed.
1018 * BUG: smb_packet_t data structures were not completely initialized
1021 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1022 Denied" because that causes the Explorer Shell to try again until
1023 access is obtained. Instead return "Remote Resources" which allows
1024 the shell to move on and treat the error as transient.
1026 * BUG: when initializing the NCBreturns structure, separate Event objects
1027 were created for each NCB although a single Event object was supposed
1028 to be shared by all.
1030 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1033 * BUG: smb_tran2Packet_t objects were not being properly referenced
1036 * BUG: directory path creation did not handle the case of multiple
1037 directories requiring creation in one attempt
1039 * BUG: SMB requests which required an Extended Response were ignored.
1040 This prevented some files from being written to AFS volumes.
1042 * BUG: character strings were being freed even after they were
1043 inserted into in use data structures
1045 * BUG: inconsistent usernames were used when High Security mode was
1046 enabled. (there is still much to do in this area)
1048 * BUG: pioctl() calls which require out of band RPC operations were
1049 susceptible to race conditions when performed by multiple processes
1051 * BUG: memory allocation and deallocation crossed instances of the
1052 C Runtime Library producing memory leakage and corruption in
1053 afscreds and the client configurator.
