3 * A bug has been fixed in the auto-generation of Freelance root.afs
4 symlinks which produced random entries in the \\AFS\all directory.
6 * Support has been added for multi-homed servers
9 * Added a new registry value, "StoreAnsiFilenames", which can be used
10 to force the use of ANSI character sets instead of OEM Code Pages.
11 This feature is useful when users require the ability to create
12 filenames with 8-bit characters and need to access the files from
13 both Latin-1 based Unix systems as well as from Windows.
15 Activation of this feature will prevent access to files stored with
18 * Shutdown all SMB threads in a synchronized manner when stopping the
21 * There is currently a maximum cache size of 1.3GB. The limit is imposed
22 by the largest contiguous block of unused memory within the 2GB process
23 space which can be assigned to the memory mapped file. Unfortunately,
24 when the executable digital signature verification code is activated
25 Windows sees fit to further segment the process memory which in turn
26 reduces the size of the maximum cache file to less then 800MB. If
27 larger cache sizes are desired, a new registry value should be set:
29 HKLM\SOFTWARE\OpenAFS\Client (DWORD) "VerifyServiceSignature" = 0x0
31 Setting this value will disable the runtime verification of digital
32 signatures on afsd_service.exe and the afs dlls which it loads. It
33 will not disable the the version number check on those same files.
34 The signature verification is not a security messure and is only meant
35 to enhance the ability to afsd_service.exe to detect potential
36 destablizing mixtures of DLLs from incompatible distributions.
38 Added code to auto-disable the signature verification check if
39 the desired cache size is greater then 700MB.
41 * Windows' WinTrustVerify(WIN_SPUB_ACTION_PUBLISHED_SOFTWARE) is
42 used to verify the validity of the afsd_service.exe binary
43 as well as each of the AFS DLLs loaded by the service. Not only
44 must the digital signature be valid but the signatures of the
45 DLL must be signed by the same entity as the service.
47 * Implement new functions: cm_freelanceMountPointExists and
48 cm_freelanceSymlinkExists. Use them along with other validity
49 checks in cm_freelanceAddMount and cm_freelanceAddSymlink to
50 ensure that name collisions do not occur and that empty strings
51 are not valid file names.
53 A symlink may not have a name which would resolve to a valid
54 cell name. Doing so would prevent access to the cell.
56 * Add missing cm_HoldSCacheNoLock call to Freelance mount point
57 re-initialization code. The reference counts of the fake root.afs
58 volume scache object(s) would become invalid when the mount point
59 or symlink lists were altered.
61 * Add registry entries to provide mappings from the afsdsbmt.ini
62 to the new locations for applications which count on the use
63 of the old Profile file APIs. These apps are likely to fail
64 if the user does not have administrator privileges and the
65 registry is locked down.
67 * The afs_config.exe submounts dialog had two errors.
68 First, attempts to remove entries failed because the registry
69 key was being opened without KEY_WRITE privileges.
70 Second, when editing a submount entry, changing the name
71 would add a new key and leave the original one in place.
72 Now the original submount will be removed if its name is
75 * In recent months there have been several incidents in which
76 users have experienced problems starting or accessing
77 afsd_service.exe and after significant effort has been spent
78 it has turned out that they have two versions of AFS on the
79 machine or an inconsistent set of DLLs.
81 Code has now been added to afsd_service.exe which will walk
82 the list of modules loaded by afsd_service.exe and validate
83 that the version of the AFS DLLs matches the version of the
84 afsd_service.exe executable. If they do not match the service
87 * When Freelance mode is enabled and there is no registry
88 key HKLM\SOFTWARE\OpenAFS\Client\Freelance, afsd_service.exe
89 will attempt to import the afs_freelance.ini file contents.
90 If the file does not exist, it was creating a dummy file
91 with a r/o and r/w entry for the default cell and then
92 importing those values.
94 This process has been changed. The temporary file is no
95 longer created. Also, both the OpenAFS Client install
96 directory as well as %WINDIR% are checked for previous
97 afs_freelance.ini files.
99 * Added support for VL_GetEntryByNameN(). Still need to add
100 support for VL_GetEntryByNameU() for multi-homed support.
102 * Fix a deadlock situation in afscreds.exe when canceling an
103 auto-generated Obtain Tokens dialog
106 * Fix the locking of objects during Directory Searches in the
107 SMB/CIFS server. The failure to properly lock the reference
108 counts was resulting in the premature freeing of smb_dirSearch_t
109 objects while they were still in use by the SMB/CIFS client.
110 This does not solve the "Invalid Handle" problem.
112 * Fix Find Cell By Name pioctl call to return a valid cell
113 name for the Freelance fake root.afs volume.
114 "Freelance.Local.Root".
116 * Fix the Explorer Shell Extension Symlinks->Add operation.
117 The dialog template was missing and the link destination
118 string was too short.
120 * Add support for symlinks to Freelance root.afs volume
121 Stored at HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks
122 <number> = "<linkname>:<relative-path>."
123 Use symlink.exe to create, list, or remove
125 * Remove the fallback to the use of KFW's KRB4 library when obtaining
126 tokens. We never obtain KRB4 tickets.
128 * Fix AFS Client Configuration Control Panel to support new SysName
130 * Fix a bug in afsd_service.exe which could result in the SysName
131 not being read from the registry.
134 * Add code to block the issuance of AFS tokens by aklog.exe or
135 afscreds.exe when the Kerberos 5 principal name contains a dot.
137 * Modify the IsAdmin() function to always treat the local SYSTEM
138 account as an AFS client administrator. Affects fs.exe and
141 * Modify the internal handling of Quota Exceeded errors
143 * Upgrade all reference count fields in the Windows cache manager
144 and the osi library to use unsigned long instead of signed short.
145 A similar fix has been applied to the afs rpc (rx) library.
147 * fix the Windows cache manager to prevent it from replacing the
148 rx_connection object associated with the cm_conn_t object on each
149 and every operation if "fs crypt" was set. This explains the
150 dramatic performance difference when crypt is used vs clear.
151 The problem: 'cryptall', a boolean flag indicating whether or not
152 "fs crypt" is set, was being compared to the rx_connection
153 cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
154 1 != 2 and therefore the rx_connection was always destroyed
155 and replaced on each and every operation.
157 Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
158 It is not safe for the cm_conn_t object to not be locked because
159 rx_DestroyConnection might be called from another thread if:
160 - the user's tokens have changed or expired
161 - the crypt mode has changed
163 This fix appears to have also taken care of the problems associated
164 with Overlapped Writes resulting in Delayed Write errors.
166 * fix NSIS installer's AdminGroup.exe to properly create and
167 remove groups when given -create or -remove. The string comparison
170 * fs sysname now accepts a list of sysname values
172 * added a new registry value HKLM\SOFTWARE\OpenAFS\Client "IoctlDebug"
173 DWORD which when set to a non-zero value will cause error message
174 text to be output to stderr from the pioctl() routine. Useful in
175 debugging failures of fs.exe, tokens.exe, etc.
177 * added a test to the power management code to only perform a
178 flush operation if there is at least one network adapter which
179 is not a loopback adapter.
181 * Fix bug in loading of registry value HKLM\SOFTWARE\OpenAFS\Client
182 "EnableKFW". This value will not be read if the key
183 HKCU\SOFTWARE\OpenAFS\Client exists; even if the "EnableKFW"
184 value under that key does not.
186 * provide mechanisms to force the use of krb524d for Kerberos 5
187 ticket to AFS token conversion. For afslogon.dll and afscreds.exe
188 there is a new registry value "Use524" and for aklog.exe a new
189 command line parameter "-m".
191 * Fix the pattern matching algorithm to properly match patterns
194 * smb_ReceiveCoreRename() was factored to produce smb_Rename()
195 which is used by both the original function and the new
196 smb_ReceiveNTRename(). smb_ReceiveNTRename() supports the
197 creation of HardLinks in addition to Renaming. smb_Link()
198 is a new function which creates HardLinks via cm_Link().
199 cm_Link() is a new vnodeops function which creates links
202 smb_ReceiveNTRename() does not support the File Copy and
203 Move Cluster Information operations described in its interface.
204 ReceiveNTRename is under documented in CIFS-TR-1p00_FINAL.pdf.
206 * When opening files via symlinks, we should follow the symlinks
207 until we reach the actual file stat cache entry. The stat cache
208 entry of the file should then be stored in the FID instead of
209 stat scache entry of the symlink.
211 * return bad operation errors for all unimplemented functions
212 even if we do not know the functions exist.
214 * Log bad packets and unknown operation packets to the trace log
216 * Map CM_ERROR_BADOP to STATUS_NOT_SUPPORTED instead of
219 * Update list of known CIFS operations to include all those listed
220 in CIFS-TR-1p00_FINAL.pdf.
222 * Modify the handling of HKLM\SOFTWARE\OpenAFS\Client\Submounts
223 to support the REG_EXPAND_SZ type.
226 * A new Windows authorization group "AFS Client Admins" is now
227 created and populated with the members of the "Administrators"
228 group. The group is used to determine which accounts on the
229 machine may be used to modify the AFS Client Configuration via
230 the UI and command line tools. afs_config.exe, fs.exe,
232 * Modify the WinLogon Logoff Event Handler to query NT4 domain
233 controllers for the remote profile path if Active Directory
234 services are not available.
236 * Fix aklog.exe to not add the AFS ID to the username
238 * PTS registration of new users to foreign cells has been added to
241 * The cm_Daemon thread is used to perform checks for
242 down servers, up servers, volumes, callback expirations,
243 lock maintenance and token expiration. Due to a gaff in
244 larger integer division the thread never performed any
245 work. Instead the current time computation would always
246 be less then the trigger times. This had an adverse affect
247 on the client's ability to maintain communication with servers,
248 keep volumes up to date, and flush user tokens and acls
249 when they have expired. This was broken when the 1.3 branch
250 was modified to support VC7 which no longer included
253 * An initialization problem with the Freelance code was
254 detected while fixing the callbackRequest. The cm_rootSCachep
255 object is obtained during afsd_InitDaemons() but the callback
256 information is incomplete. The callback information will not
257 be obtained until cm_MergeStatus is called from within
258 cm_GetCallback. Unfortunately, cm_SyncOp did not properly
259 test for the conditions under which the callback information
262 * Reports have been filed indicating that callbacks were
263 being lost. An examination of the code indicated that the
264 cm_server_t objects were not being properly reference
265 counted by the cm_scache_t and cm_callbackRequest_t objects.
266 In particular, the cm_server_t objects may have been freed
267 from beneath the cm_conn_t objects.
269 All of the reference counting is now done via the functions:
274 this improves the ability to track the referrals.
276 Each cm_BeginCallbackGranting Call now allocates a reference
277 to the cm_server_t. The cm_EndCallbackGrantingCall either
278 frees the reference or transfers it to the cm_scache_t
279 cbServerp field. These are then appropriately tracked
280 through the cm_Analyze call.
282 * Ensure that the dnlc hash table is the same size as the
283 dir name hash table (as per original author's note).
284 Increase the dnlc CM_AFSNCNAMESIZE to a multiple of 8
285 for compatibility with 64-bit systems.
287 * fix smb_ApplyV3DirListPatches to properly apply the hidden
288 attribute to dotfiles when the infoLevel < 0x101 and
289 cm_SyncOp has failed.
291 * Fix the Freelance registry initialization code. There
292 was a possibility that some systems could end up with
293 garbage in the registry during a clean install.
296 * file and directory names beginning with "." will now be given the
297 hidden attribute when the volume access is anonymous. this matches
298 the behavior when the volume access is via an authenticated user.
300 * Added a change monitor to the HKLM\SOFTWARE\OpenAFS\Client\Freelance
301 key. When a change occurs mark the root.afs data as invalid and
302 for it to be reloaded on the next access. This allows administrators
303 to modify the mount point list without restarting the service.
305 The freelance client used to provide a fake modification time for
306 the root.afs volume data and its mount points of 7/09/2001 14:24 EDT.
307 Added code to extract the last modification time of the Freelance
308 registry key and use that instead. The time now represents the
309 most recent mount point change.
311 * PTS registration of new users to foreign cells has been added to
314 * Additional Cache Control and Credential Manager options have been
315 added to the WiX installer. See deployment guide for details.
317 * The CachePath setting is now optionally a REG_EXPAND_SZ type
319 * The WiX installer has been upgraded. Version 2.0.1927.1 is now
322 * The loopback installation code may have had a problem updating the
323 %ETC%\HOSTS file which could have resulted in a premature failure.
324 Work around code has been added for the case where the file cannot
327 * The default max chunksize was increased from 15 (32K) to 17 (128K)
328 because Windows sends 64K blocks when using overlapped writes.
330 * The default number of server threads was increased from 4 to 25 to
331 better handle overlapped writes.
333 * The "AfscredsShortcutParams" registry value was not being properly
334 loaded by afscreds.exe. Therefore, the default value was always being
335 used instead of the value set by the installer.
337 * Windows XP provides downgrade attack detection to prevent an attacker
338 from being able to force the use of NTLM simply by disrupting
339 communication with the KDC. This attack cannot exist between the
340 Windows CIFS client and the AFS Client Service. Therefore, when a
341 downgrade has been detected the afs pioctl library will force the
342 establishment of a new CIFS connection using NTLM.
344 * A locking error was discovered surrounding all references to volume
345 server lists within the cm_cell.c source file.
347 * The logged into Windows username was incorrect on Terminal Server
350 * A new registry value "NonPersistentCaching" was added to the service
351 parameters key. When set to a non-zero value, the afs cache is stored
352 in the Windows paging file. There are two limitations to choosing
354 1. when persistent caching is implemented it won't work with
355 this flag set since there will be nothing to persist.
356 2. with this flag set the initial paging allocation cannot be
357 changed while the service is running
359 * An initialization bug was discovered in aklog.exe which affected users
360 who have a domain name for their afs servers which could not be mapped
364 * afs_config.exe now validates cell names against DNS in addition
365 to the CellServDB file.
367 * In order to allow the freelance client to connect to a volume with ID
368 equal to 1 on the default cell we changed the fake root.afs volume ID
369 once again. This time we choose 0xFFFFFFFF. In addition, we change
370 the cell ID of the fake root.afs volume from 1 to 0xFFFFFFFF as well.
371 It will now be impossible for a volume ID to match that of another
372 cell unless the client is connected to 0xFFFFFFFD cells. That should
373 be enough room for growth.
375 * Fix "fs mkmount" command to work with UNC paths and when
376 started from non-AFS drives. It is now possible to create a mount
377 point in the freelance fake root.afs volume with the command
379 fs mkmount \\AFS\all\<directory-name> <volume-name> <cellname>
383 fs mkmount \\AFS\all\openafs.org root.cell openafs.org
384 fs mkmount \\AFS\all\.openafs.org root.cell openafs.org -rw
386 * The algorithm used to re-attempt access to the servers associated with
387 a volume has been altered to properly address the case in which all
388 servers have been marked down. The previous algorithm did not reset
389 the server's down flags so the servers were never actually retried.
390 This caused a problem with active volumes if the network connectivity
391 was lost as could be the case with a network cable removal, wireless
392 drop, or laptop hibernation. With the fix volume access is restored
393 almost instantenously when network connectivity becomes available.
395 * Support for SMB/CIFS browsing has been added to the AFS Client Service
396 SMB server. It is now possible to use "NET VIEW \\AFS" to obtain a
397 listing of AFS submounts and freelance mount points. Support for
398 NETSHAREENUM, NETSHAREGETINFO, NETSERVERENUM2, NETSERVERGETINFO
399 significantly enhances the behavior of AFS volumes within the Explorer
400 Shell. For instance, "AFS" now shows up as server in the Explorer
401 with each submount or freelance mount point visible as a share.
402 The right click menu in each folder now works with full functionality
403 on a consistent basis.
405 * The network provider can be configured to have different behavior
406 depending on the domain that the user logs into. These settings are
407 only relevant when using integrated login. A domain refers to an
408 Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
409 local machine (i.e. local account logins). The domain name that is
410 used for selecting the domain would be the domain that is passed into
411 the NPLogonNotify function of the network provider. (see registry.txt
414 * Added a new registry value [HKCU\SOFTWARE\OpenAFS\Client]
415 "Authentication Cell" which may be used to specify a default
416 authentication cell for afscreds.exe which is different from
417 the default cell for the AFS Client Service daemon.
419 * Added a Logoff WinLogon Event Notification function to afslogon.dll.
420 afslogon.dll moved to %WINDIR%\System32\.
421 New registry entries added to register the dll for Winlogon events.
423 The logoff event will now force a call to ktc_ForgetAllTokens()
424 using the context of the user being logged off as long as the
425 user's profile is not loaded from within AFS. If the profile
426 was loaded from AFS we can't release the tokens since the Logoff
427 event is triggered prior to the profile being written back to
428 the its source location. This is now performed in an XP SP2
431 * Windows XP SP2 Internet Connection Firewall interoperability
434 * The %WINDIR%\afsdsbmt.ini contains four sections:
435 Submounts, Drive Mappings, Active Maps and CSC Policies.
436 The Submounts and CSC policies are now stored in the registry under
437 [HKLM\SOFTWARE\OpenAFS\Client\Submounts]
438 [HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
439 The Drive Mappings and Active Maps are stored in the registry under
440 [HKCU\SOFTWARE\OpenAFS\Client\Mappings]
441 [HKCU\SOFTWARE\OpenAFS\Client\Active Maps]
443 There is no automatic migration of this data as it would be impossible
444 to consistently migrate data to user profiles which may not be active
445 when the machine is updated.
447 * The %WINDIR%\afs_freelance.ini contains lists of mountpoints for the
448 fake root.afs volume. For the same reasons as for the cellservdb file,
449 this information should not be in %WINDIR%. This information is now
450 kept under the registry key
451 [HKLM\SOFTWARE\OpenAFS\Client\Freelance]
453 The data from the afs_freelance.ini file will be automatically
454 migrated to the registry on first execution of afsd_service.exe
456 * Keeping the CellServDB file in the location %WINDIR%\afsdcell.ini is
457 troublesome for several reasons. One, it is confusing for those who
458 expect the file to be named "CellServDB" instead of "afsdcell.ini".
459 Two, this file is not a Windows Profile formatted file. Three,
460 applications should not be reading or writing to %WINDIR%. It causes
461 problems for Windows Terminal Server.
463 The new location of CellServDB will be the OpenAFS Client install
464 directory which is by default C:\Program Files\OpenAFS\Client and can
465 be determined by querying the registry for
466 [HKLM\SOFTWARE\TransarcCorporation\AFS Client\CurrentVersion]PathName
468 The existing afsdcell.ini will be migrated by the NSIS installer.
469 The Wix installer must still be updated to do the same.
471 * Change NSIS installer to use DNS by default; to remove Integrated Logon
472 High Security mode; and to add Terminal Services compatibility registry
473 entries to allow the OpenAFS tools to find the afsdcell.ini and other
474 configuration files in %WINDIR%.
476 * Add support for authenticated SMB connections. This will remove
477 the need for high security mode in most situations. Both NTLM
478 and Extended Security (GSS SPNEGO) modes are supported. Effectively,
479 only NTLM can be used even though Kerberos is now supported. The
480 reason is that it is not possible to construct a service principal
481 which is unique to each individual machine.
483 SMB Extended Auth does not work on XP SP2 unless one of two registry
484 modifications are made:
486 (1) To disable the check for matching host names on loopback connections
487 set this key. This does not require a reboot:
489 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
490 "DisableLoopbackCheck"=dword:00000001
492 (2) To add the AFS SMB/CIFS service name to an approved list. This
493 does require a reboot:
495 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
496 "BackConnectionHostNames"=multi-sz "AFS" "MACHINE-AFS"
498 afsd_service.exe will automatically add the current Netbios Name
499 to the BackConnectionHostNames list and then temporarily disable
500 the loopback check for one cycle of startup/shutdown of the service.
501 We assume most folks do not start/stop without a reboot so this
502 will be adequate in most cases.
504 * Fix security hole in afslogon.dll which allowed passwords to be
505 sent in clear text to the KDC in a misformed principal name.
507 * Fix cm_GetCell() to properly handle expired dns entries
510 * If Freelance mode is active and the afs_freelance.ini
511 file does not exist, do not create an empty file.
512 Instead create a file containing ro and rw mountpoints
513 to the default cell using the standard conventions.
515 * Modify the Freelance support to handle the ability
516 to create rw mount points in the fake root.afs volume.
518 * Changed the RPC mechanism used for token setting from
519 named pipes to local. Use of named pipes can be restored
520 by setting the environment variable AFS_RPC_PROTSEQ to
523 Named pipes were required when a Windows 9x system was
524 using a NT system in gateway mode which is incompatible
525 with our use of local loopback adapters.
527 * In afscreds.exe, if a username of the form user@REALM is
528 specified and no password is specified, do not perform a
529 kinit operation. Only perform the aklog functionality.
531 * Add a new registry value which allows the number of processors
532 on which afsd_service.exe executes to be restricted. Valid
533 values are 1..numOfProcessors
535 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAfsDaemon\Parameters
539 * A second MSI based installer option is now available.
541 * Fixed Kerberos 5 kinit functionality in afscreds.exe to properly
542 request tickets for user/instance@REALM instead of just user@REALM
544 * Modify the Power Management Notify routine to wait for the Hard Dead
545 timeout period instead of a fixed 19 seconds. With the longer timeout
546 periods Hibernation and Standby could never succeed when network
547 connectivity is not available.
549 * The following fs.exe commands are now restricted to Administrator:
550 - checkservers with a non-zero timer value
553 - sysname with a new sysname list
562 setting the default sysname for a machine should be done via the
563 registry and not via "fs sysname".
565 * NSIS installer adds options to install Debugging Symbols
566 and the Microsoft Loopback Adapter; the user is now also
567 given the ability to select the afscreds.exe startup options.
569 * Build system modified to generate symbols for FREE (aka RELEASE)
570 builds as well as CHECKED (aka DEBUG) builds
572 * Sites which have a volume ID of 0x20000001 assigned to their
573 root.cell volumes have been experiencing problems with accessing
574 the root.cell volume of their cell when Freelance mode has been
575 active. This was because 0x20000001 was assigned to the fake
576 root.afs volume created by freelance. The fake volume id is
577 now set to 0x00000001 to prevent conflicts.
579 * The timeout logic in the AFS Client Service has been wrong
580 for sometime. It is based on two different assumptions.
581 First, the SMB client timeout is a fix value as was the case
582 with OS/2 Lan Manager. This assumption is incorrect. The
583 SMB timeout in Windows is a dynamic value computed based upon
584 a fixed minimum timeout to which is added time based upon the
585 size of the request and the performance characteristics of
586 the connection. Second, it is the responsibility of the
587 SMB Server to enforce the timeout requirements of the client.
588 This is untrue. The SMB Server cannot be expected to know
589 the requirements of the client. More importantly, if the
590 SMB server uses the SMB client timeout as a value to restrict
591 its behavior as an RX client, the performance characteristics
592 of the local SMB session would be used to prematurely terminate
593 WAN connections with significantly different performance
596 The timeout logic has therefore been modified in the following
598 . the Lan Manager Workstation (SMB) Session Timeout is used only
599 as a basis for configuring the Connection Dead Timeout
600 and Hard Dead Timeout values. The Connection Dead Timeout
601 must be at least 15 seconds longer than the SMB Timeout
602 and the Hard Dead Timeout must be at least double the
603 Connection Dead Timeout.
604 . New registry entries have been added to allow the Connection
605 Dead Timeout and Hard Dead Timeout values independent of the
606 Lan Manager Workstation Session Timeout
607 . The test to enforce the SMB Client Timeout has been removed.
609 One of the side-effects of removing the enforcement of the SMB
610 Client Timeout is that regardless of whether or not the SMB client
611 is available to receive the response (and how would the SMB server
612 know) the RX protocol response can be used to update the AFS
613 Client Service state for ready access by future SMB client
616 This should be the end of the "Server paused or restarting messages"
618 * Add support for arbitrary UNC paths to the pioctl() support.
619 This enables the fs commands as well as the AFS Shell Extension
620 to work correctly when UNC paths are being used.
622 * Fix afscreds.exe (by updating afskfw.lib) to search for cells via
623 DNS if the cell configuration cannot be determined via CellServDB
625 * Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
626 are ever set more than once at a time
628 * Fix the management of lists of cm_cell_t structures when using
629 DNS to lookup cell information. The previous code would fail to
630 reuse the same cellID for a cell if DNS was used more than once
631 for a given cell name. When the ttl expired, a single cm_cell_t
632 could be inserted into the cm_allCellsp list more than once
633 producing a loop. In addition, the vlServerp list belonging to
634 the cell was not freed resulting in improper refCounting of the
637 * Add DNS support to cm_IoctlNewCell() which previous only examined
640 * Add cm_FreeServer() function and call it from cm_FreeServerList()
641 to properly garbage collect cm_server_t objects
643 * Add numVCs variable to smb.c to track the number of smb_vc_t
644 objects created and use it to initialize the vcID field which
645 previously was set to 0 in all objects resulting in FindByID
648 * Fixed DNS lookups to work consistently throughout the OpenAFS
649 product instead of just from within the afsd_service.exe
651 * Added a runtime check to ensure that AFS Client Service SMB
652 Server is accepting connections before attempting to mount
655 * Read IP addresses for volume servers out of the CellServDB
656 file if gethostbyname() on the hostname fails.
658 * Fix getcellconfig() to populate both the Hostnames as well
659 as IP addresses when loading cell data via DNS
661 * Increase the Connection Dead Time to 50 from 20 seconds
662 Increase the Hard Dead Time to 120 from 40 seconds
663 (matches the Unix values)
665 * Fixed an assertion validating the number of allocated NCBs
667 * Fixed the build environment to consistently build for
668 Windows 2000 and above. (APPVER = 5.0)
670 * Fixed rx_debug to properly validate the receipt in incoming
671 data with select() and recvfrom(). Do not copy data out of
672 the socket buffer unless success is indicated.
675 * afsd_service.exe will now display a message box to the
676 desktop when it terminates due to an IP Address Change.
678 * installer no longer deletes AFS Server configuration data
681 * installer generates a warning dialog if the RPC service
682 is not properly configured
684 * installer compressed with lzma instead of bzip2
686 * afsd_service.exe shutdown crash solved once and for all
688 * reference counting of smb_vc_t data structures improved
690 * name space collision of smb_fid_t event objects corrected
692 * the output of "fs memdump" is now written to
693 %WINDIR%\TEMP\afsd_alloc.log
695 * the file TaAfsApp_1033.dll is now properly installed allowing
696 the User Manager to start
698 * a new algorithm is used for computing filename pattern matches
700 * afscreds.exe now accepts user names containing instance
703 * Fix the Directory Name Lookup Cache to be case-sensitive.
704 This is crucial in environments in which a Windows client
705 is accessing a directory with more than one filename that
706 differs only by case. If the directory contains "FOO"
707 and "Foo". You want "DEL Foo" to delete the correct one.
708 We still have a problem in that "DEL foo" will delete a
709 random filename. This will be addressed in a future release.
711 * Fix afscreds.exe -M option (renewMaps) to work when High
712 Security mode is off. Also, remember to disable the ActiveMap
713 flag in afsdsbmt.ini when a drive mapping is removed.
715 * Updates to NSIS installer script. AFS Server configuration
716 data will not be destroyed on un-install or re-install.
717 Use a better compression algorithm.
719 * afslogon.dll now uses KFW to obtain tokens when available
721 * afslogon.dll when given an all uppercase username will
722 attempt to authenticate with both the uppercase name
723 and an all lowercase variation
725 * DST modification removed. The fix appears to make things
726 worse after a reboot of the machine.
728 * fs.exe: added "cscpolicy" which is used to
729 change client side caching policy for AFS shares
731 Usage: fs cscpolicy [-share <AFS share>] [-manual] [-programs]
732 [-documents] [-disable] [-help]
734 * Several uninitialized variables have been initialized
736 * It is now possible to obtain tokens using cross realm
737 Kerberos within afscreds.exe:
739 user: jaltman@ATHENA.MIT.EDU
741 Will obtain a cross realm ticket for jaltman/DEMENTIA.ORG@ATHENA.MIT.EDU
742 will will in turn be used to obtain afs@DEMENTIA.ORG.
743 The resulting token will be stored with the display name
744 jaltman@ATHENA.MIT.EDU@dementia.org
746 * aklog.exe has been added to the client
748 Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]]
749 [[-p | -path] pathname]
753 -d gives debugging information.
754 krb_realm is the kerberos realm of a cell.
755 pathname is the name of a directory to which you wish to authenticate.
756 -noprdb means don't try to determine AFS ID.
757 -5 or -4 selects whether to use Kerberos V or Kerberos IV.
758 (default is Kerberos V)
759 No commandline arguments means authenticate to the local cell.
762 * All of the resource files have been restructured to adhere to
763 a set of rules IBM implemented for loading string resources.
764 These rules had either been forgotten or were not discovered
765 by folks working on the OpenAFS sources. The end result was
766 memory corruption. This is primary item which was preventing
767 the AFS Server from working.
769 * Increased the size of the maximum ticket size stored in a token
770 from 344 bytes to 12,000. Increased the buffers used to convey
771 messages between the pioctl() caller and the SMB Server from
772 1000 bytes to 12,512. The code appeared to have been writing
773 above the top of the stack by quite a few number of bytes.
774 (The increased ticket size is necessary for the next item.)
776 * When obtaining AFS Tokens via KFW, krb524 is no longer required.
777 Instead the raw Kerberos 5 ticket is used in its entirety. This
778 is extremely important as it allows us to use pure Kerberos 5 KDCs
779 as the source of the AFS authentication. The use of up to 12,000 byte
780 tickets will allow tickets produced by all versions of Microsoft
781 Active Directory to be used.
782 - create a user account.
783 - designate it DES only
785 - specify its UPN to be "afs@realm"
786 - assign a SPN of "afs/cellname" to the UPN with setspn.exe
788 * Do not enforce the funky 8dot3 pattern matching rule that the first "."
789 is special when using long file names. (you must use "*.*" and not "*")
790 Instead only enforce it when performing 8dot3 searches.
792 * Fixed the DST problem with creation times being set one hour ahead
794 * Fixed the problem when using \\afs\cell-alias. For example,
795 \\afs\uncc instead of \\afs\uncc.edu. Do not a new cell struct
796 for the alias name; instead simply expand the name. One of the
797 symptoms of this problem was a loss of acquired tokens.
799 * Fixed the AFS Shell Extension. The Symbolic Link menu was empty
800 of strings. (Only English strings provided.)
802 * Fixed the installer to properly replace in use files.
804 * Fixed the build system to cleanup generated component version files
806 * The release build compiled with MSVC 6.0 compiler to avoid the
807 afsd_service.exe shutdown crash. This does not solve the problem
808 but simply avoids it for the time being.
812 * fix afslogon.dll to not corrupt memory when High Security mode
815 * fix afsd_service.exe to not attempt to restore the stack when
816 an exception occurs. (not safe in multi-threaded programs)
818 * fix uninstaller to properly remove the CRT and MFC DLLs
820 * remove a Message Box from afscreds.exe when getcellconfig()
821 fails on a kerberos realm which is not a cell
823 The following is a list of changes to the OpenAFS for Window client
826 * "fs setserverprefs" will leave afsd service deadlocked
828 * "vos listaddrs" will core dump
830 * installer sets the appropriate keys to support Integrated Logon
832 * installer disables the "Find Lana by Name" functionality as it
833 was causing headaches for many users
835 * fix the intermittent crash of the power management thread when
836 shutting down the AFS Client Service
838 * optimizes the obtain drive mount list functionality which is
839 executed every time the mount tab in afscreds.exe and afs_config.exe
840 are refreshed. (this happens a lot)
842 * fix the service shutdown logic. add the STOP_PENDING state
843 and do not accept additional service events after we declare
846 The following is a list of changes to the OpenAFS for Window client
849 * flexelint was run against the source tree and hundreds (perhaps
850 thousands) of corrections were applied to ensure prototypes
851 were in use; types were used consistently; variables were
852 initialized; unused variables were removed; etc.
854 * A wide variety of instrumentation was added including the
855 ability to produce a stack trace from within afsd_service.exe
858 * Dynamic configuration of the RDRtimeout value based upon the
859 LanMan Workstation Session Timeout
861 * The mount root no longer needs to be called "/afs". This
862 is now set by a registry value "MountRoot" within the key
863 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
865 * The cell list is now only read out of afsdcell.ini when the
866 file changes instead of each time a cell is resolved.
868 * Thread synchronization was added to cm_server.c and ktc_nt.c
870 * All calls to GlobalAlloc()/GlobalFree() were replaced with
871 calloc()/free(). The Global functions were needed on Windows 3.x
872 but have caused a variety of problems on the Win32 platforms.
873 Avoiding them is highly recommended by several Microsoft
874 Knowledgebase articles
876 * Support for Symbolic Links added to the AFS Shell Extension
878 * Added a registry value "OverlayEnabled" to determine if
879 Shell Extension Overlays should be enabled.
880 HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
882 * New Build system to support VC6, VC.NET, VC.NET2003 compilers and
883 separate trees for checked and free builds. Build system supports
884 a custom directory src\WINNT\extra which can be used as a grafting
885 location of organization specific additions to the build tree.
887 * New installer built using NSIS 2.0.
889 * Named all kernel objects in order to allow them to be monitored
890 with tools such as SysInternals' ProcExp.exe.
892 * Introduced new EventLog framework for AFSD
894 * Introduced Power Management interface to AFSD for Standby and
895 Hibernate modes to allow cache to be flushed prior to network
898 * Utilize Win32 DNSQuery API instead of internal routines. This
899 allows DNS SRV queries to be sent to all current domain name
900 servers. Not just one specified in an INI file. DNS is now
903 * "NetbiosName" registry value may be used to specify a fixed
904 Netbios Name such as "AFS" to be used instead of "HOSTNAME-AFS"
905 when the loopback adapter is in use. If you need to use the
906 old notation with a loopback adapter installed specify a registry
909 "NetbiosName" REG_EXPAND_SZ = "%COMPUTERNAME%-AFS"
911 * Refactor all modules which depend on LAN Adapter and NetbiosName
912 determination in a new library: lanahelper.lib. This allows for
913 consistent behavior throughout the product.
915 * Move the afsd.log and afsd_init.log files to the directory specified
916 by the "TEMP" environment variable. This is usually %WINDIR%\TEMP
917 for services. Added the Date to the log entries.
919 * New registry value "RxMaxMTU" used to limit the size of the RX
920 packets sent by the AFS Client Service to the Server. In order
921 to enable OpenAFS to work across the Cisco IPSec VPN the packet
922 size must be restricted to 1264 or smaller. The latest NSIS
923 installer sets a value of 1260 by default.
925 * New registry value "RxNoJumbo" to disable the use of Jumbo Rx
926 packets. This is not needed in order to work across the Cisco
927 VPN but might be needed for other network environments. This
928 value is not set by the NSIS installer.
930 * New registry value "HideDotFiles" is used to apply the Hidden
931 attribute to files whose names begin with a '.'. This value
932 is set by the NSIS installer.
934 * New registry value "MaxMpxRequests" allows the maximum number
935 of multiplexed sessions to be configured at run time. This
936 value is not set by the NSIS installer. The default value is
939 * New registry value "MaxVCPerServer" allows the maxmimum number
940 of VCs per server to be configured at run time. This value is
941 not set by the NSIS installer. The default value is 100.
943 * New registry value "AllSubmount" allows the "all" submount to
944 be disabled by setting its value to 0x00.
946 * Allow cells names to be valid mount points
947 \\<netbiosName>\<cellname>
949 * Store the active state of drive mappings in order for afscreds.exe
950 to restore them upon startup
952 * Add exception handling to generate a Stack Trace to the afsd_init.log
953 file if one happens to occur.
955 * Add lots of logging to help detect the cause of invalid SMB packets
957 * Enable Kerberos for Windows to be used to obtain AFS Tokens via
958 conversion of Kerberos 5 "afs" service tickets. Supports auto-
959 renewal of expiring tokens as long as afscreds.exe is running.
961 * New afscreds.exe command line options:
963 -M = renew drive maps
964 -N = ip address change detection
967 * New registry value "EnableKFW" in {HKCU,HKLM}SOFTWARE\OpenAFS\Client
968 determines whether or not MIT Kerberos for Windows should be used
969 to obtain tokens via Kerberos 5 tickets.
971 * New registry value "AfscredsShortcutParams" in
972 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
973 determines the command line parameters to be specified when "fixing"
974 the AFS Shortcut in the user's startup folder.
976 * The "ShowTrayIcon" registry value has been moved from
977 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
978 {HKCU,HKLM}SOFTWARE\OpenAFS\Client
980 * The <cell name> registry values used to store the token expiration
981 reminders have been moved from
982 HKLM\Software\TransarcCorporation\AFS Client\AfsCreds to
983 {HKCU,HKLM}SOFTWARE\OpenAFS\Client\Reminders
985 * Obtain the Logon User Name from the Explorer key when available
987 * new text document doc\txt\winnotes\registry.txt lists all registry
988 values used by OpenAFS (excluding the AFS Server)
990 * BUG: rx_securityClass objects were not properly reference
991 counted and were never freed.
993 * BUG: reduce the number of conditions under which CM_ERROR_TIMEOUT
994 would be generated. The existence of a server does not imply
995 that it is not down. If all of the servers for a cell are down
996 return CM_ERROR_NOSUCHVOLUME instead. This prevents the Explorer
999 * BUG: the directory name lookup cache failed to free the entries
1000 in the cache when the name cache entries cycled. The entries
1001 in the cache would become dereferenced without being freed.
1003 * BUG: fs setserverprefs could be executed without Administrator
1006 * BUG: the number of allocated NCB objects (100) exceeded the number
1007 which could actually be waited upon by the kernel (64). Any objects
1008 which were utilized above the limit could never have event completions
1011 * BUG: smb_username_t objects were not being reference counted and
1012 were not properly freed.
1014 * BUG: smb_tid_t objects could under unusual circumstances be freed
1015 before they were no longer referenced.
1017 * BUG: smb_fid_t object pointer were frequently used even when
1018 their value could be NULL. They were not properly released and
1019 therefore they were never freed.
1021 * BUG: smb_packet_t data structures were not completely initialized
1024 * BUG: when Rx produces a CM_ERROR_NOIPC error do not return "Access
1025 Denied" because that causes the Explorer Shell to try again until
1026 access is obtained. Instead return "Remote Resources" which allows
1027 the shell to move on and treat the error as transient.
1029 * BUG: when initializing the NCBreturns structure, separate Event objects
1030 were created for each NCB although a single Event object was supposed
1031 to be shared by all.
1033 * BUG: smb_dirSearch_t objects were not being properly referenced counted
1036 * BUG: smb_tran2Packet_t objects were not being properly referenced
1039 * BUG: directory path creation did not handle the case of multiple
1040 directories requiring creation in one attempt
1042 * BUG: SMB requests which required an Extended Response were ignored.
1043 This prevented some files from being written to AFS volumes.
1045 * BUG: character strings were being freed even after they were
1046 inserted into in use data structures
1048 * BUG: inconsistent usernames were used when High Security mode was
1049 enabled. (there is still much to do in this area)
1051 * BUG: pioctl() calls which require out of band RPC operations were
1052 susceptible to race conditions when performed by multiple processes
1054 * BUG: memory allocation and deallocation crossed instances of the
1055 C Runtime Library producing memory leakage and corruption in
1056 afscreds and the client configurator.
