Don't assume that WM_DESTROY is the final message received by a
window. Verify dialog data structures when handling messages and
reset the window data field when freeing the data structure.
Zero should be considered a valid credentials type identifier in
Network Identity Manager.
When checking if an identity is configured to obtain a token for a
specific cell, don't go through the list of cells if AFS tokens
are disabled for the identity.
Similarly, when removing a token for a specific cell from all
identities, don't bother modifying identities for whom AFS tokens
are disabled.
Keep track of whether a specific cell was added to the list of
cells to authenticate for an identity because it was listed in the
configuration or because a token for the cell already existed.
Correct an off-by-one error when calculating buffer sizes for
multi strings which failed to account for a double NULL
terminator.
Don't update the cell->identity mapping if a token for that cell
could not be obtained.
If the list of cell to authenticate for an identity is empty, we
still need to write the empty string to the configuration.
Otherwise, removing all the tokens from an identity will not
result in a configuration change reflecting that.

windows-volume-status-tracking-
20070610
* changed the enum values for cm_serverRef_t state info to use a
private name space to avoid collisions (srv_)
* added a srv_deleted state for cm_serverRef_t objects. This
state is set when cm_FreeServerList() is called with the
CM_FREESERVERLIST_DELETE flag set. cm_FreeServerList() may
not always delete the cm_serverRef_t from the list if it is
still in use by another thread. the srv_deleted state means
the object's contents are no longer valid and it must be
skipped. It will be deleted the next time the object is
freed and the refcount hits zero.
* the srv_deleted state is also used when a file server reports
either VNOVOL or VMOVED instead of marking the cm_serverRef_t
as offline. This is done to prevent additional usage of the
stale vldb data while waiting for the update volume request
to complete.
* added a state field to the cm_volume_t object (enum volstate
vl_ name space) that maintains the state of the volume based
upon the states of all of the cm_serverRef_t and cm_server_t
objects.
* modified cm_UpdateVolume() to set the state of the cm_volume_t
RW, RO, and BK to either vl_alldown or vl_online. There can't
be any other states because cm_UpdateVolume() destroys any
previous knowledge we might have had regarding busy or offline
volume status
* modified cm_UpdateVolume() to update the volume name in the
cm_volume_t to the volume base name if the previous value was
a volume ID.
* modified cm_FollowMountPoint() to check to see if the volume
name is a volume ID and if so call cm_GetVolumeByID instead
of cm_GetVolumeByName. This ensures that volume IDs are always
looked up as numeric values. There is no longer a need to
maintain a separate cm_volume_t containing the string representation
of the ID value.
* Added a flags parameter to cm_GetVolumeByName() and cm_GetVolumeByID().
The first flag is a "CREATE" flag which is set by all existing
calls. The flag is not set by calls to cm_GetVolumeByID() from
the server probe code when volume status is being updated. We
do not want the server probe operation to result in additional
turnover in the cached volume data. The second flag is NO_LRU_UPDATE
which is set when the server probe code updates the volume status.
This flag will be used to prevent the server probe operation from
changing the order of the least recently used queue.
* Modified cm_GetVolumeByName to ensure that only one cm_volume_t is
allocated for a given set of normal, readonly, and backup volumes
regardless of whether or not the volume is accessed via name or
ID number. The cm_volume_t namep field is always the base name
of the volume.
* Added a new volume state, vl_unknown. This state is used as
the initial state for all cm_volume_t when the cache manager starts,
for each cm_volume_t at creation, and for each cm_volume_t when
recycling. The cache manager does not know the state of all
volumes in the world, only those that are in the cache and for
which it has queried the VLDB and hosting file servers.
* modified cm_GetVolumeByName() to initialize the state of a
volume to vl_unknown. The actual state will be set when a
cm_VolumeUpdate() call completes successfully.
* changed name of scache hash table variables to avoid ambiguity
when adding hash tables for volumes
* fix a buffer overrun in sys\pioctl_nt.c pioctl().
(thanks Asanka)
* modified cm_UpdateVolume() to handle the case in which there is
no RW volume but there is are RO volumes for a given base name.
This is done by querying for the ".readonly" volume name if the
base name does not exist in the VLDB. We never query for the
.backup name because under the current usage model a .backup
volume may only exist on the server that the read-write volume
is located. If there is no RW volume, there can be no .backup.
* Added four hash tables for cm_volume_t objects to improve the
search time of cm_GetVolumeByID(), cm_GetVolumeByName() and
cm_ForceUpdateVolume(). One each for Name, RWID, ROID, and
BKID. Three ID hash tables are necessary as long as it is
desireable to maintain a single cm_volume_t containing all
of the related RW, RO, and BK volume data. Having the RW and
RO volume data in the same object is necessary for the
implementation of cm_GetROVolumeID() which returns either the
RO or RW ID depending upon the existence of RO volume instances.
* Added a volume LRU queue so that volume reuse becomes fairer.
This does not replace the all Volumes list which is used when
it is desireable to walk a list of all the volumes whose order
is not going to change out from underneath you which makes it
safe to drop the cm_volumeLock.
* handles volume hash table updates where volume name to
volume ID number changes. The volume name remains
constant in the cm_volume_t. if a vos rename is performed,
the name of the volume will change and the volume IDs will be
updated. Subsequent access to the old volume ID will create a
new cm_volume_t with the new name.
* Added a daemon thread operation to query the state of volumes
listed as busy or offline. cm_CheckBusyVolumes() calls
RXAFS_GetVolumeStatus() for each volume ID that is marked vl_busy
or vl_offline. If the volume is now online, the status on the
volume is updated. The default period is 600 seconds. This can
be configured with the BusyVolumeCheckInterval registry value.
* Added prototype for smb_IoctlPrepareRead() which was missing a
return type in the function definition.
* Added volume id lists to the cm_server_t. These lists are
allocated in blocks of ~32 IDs. When a cm_PingServer()
detects a change in server state, the state of the cm_volume_t
is updated.
* Added volID to the cm_serverRef_t object. volID is used
to identify the volume for which the object is a referral.
cm_FreeServerList() uses the volID to remove the volume
from the cm_server_t.
* In cm_Analyze, when VNOVOL or VMOVED are received,
call cm_ForceVolumeUpdate() to force a refresh of the volume
location data.
* Added cm_VolumeStatusNotification() which is used at the moment
to log volume status changes to the trace log. It will also
be used as the access point to the File System Filter driver
notification engine.
* Added an all cm_scache_t list to cm_data. This replaces the use
of the stat cache LRU queue when we need to enumerate all
entries. The LRU list order is not static and when using it to
enumerate all entries it can result in items being missed or
items being processed more than once.
* Modified cm_Analyze(). Instead of reseting the busy or offline
state of a volume and forcing a retry of the operation
cm_Analyze will defer to the background daemon thread that will
update the state once every 600 seconds.
* Added the automatic generation of a Freelance ".root" read-write
mountpoint that refers to the root.afs volume of the workstation
cellname at the time the mountpoint is created.

FIXES 60161
A dropbox is a directory with ACLs 'li' that permits a user to create
a new file but not be able to read other files within the same directory.
The 1.5 Windows clients have not been able to write to dropboxes since
the addition of the locking code. The lock acquisition test assumed
that if the user did not have PRSFS_LOCK or PRSFS_WRITE that it would
be unable to obtain a lock. It did not take into account the special
treatment of PRSFS_INSERT by the file server and so never bothered to
ask.
As it turns out though, the locking situation is more complex than one
might think. If the server is 1.4.1 or earlier, it will not grant
any locks for users with INSERT. The PRSFS_LOCK privilege is required.
For 1.4.2 through 1.4.4, write locks will be granted if the user has
PRSFS_INSERT but a read lock will not be granted unless the user has
PRSFS_LOCK. Therefore, if the server advertises the WRITELOCKACL
capability bit if the read lock is not granted a write lock can be
attempted.
For 1.4.5 and 1.5.20 and above, the file server will grant read locks
if the user has PRSFS_WRITE or PRSFS_INSERT. (Insert only applies if
the user is the creator of the file).
This patch handles all of the above possibilities. In the pre-1.4.2
case a read-lock request will be faked locally.

20070423
the permission to obtain a write-lock is granted either by having the
"w" permission or the "i" when owning the file. The permission to obtain
a read-lock has been granted by having the "k" permission. However it
makes no sense that someone can obtain a write-lock but not a read-lock.
This patch grants permission to obtain read-locks to those who can obtain
write-locks.

linux-symlink-handling-avoid-crash-
20070418
Background: OpenAFS is vulnerable to crashing in the linux kernel symlink
code when running on kernel versions between 2.6.10 to 2.6.12. This also
includes all RHEL4 kernels, because RHEL4 includes the code from 2.6.10. The
problem is that the symlink text caching API, page_follow_link() et al, is
unsuitable for network filesystems where the page cache may be invalidated
in parallel with a path lookup.
This crash can be triggered easily by doing a bunch of path lookups
involving symlinks (e.g., stat() on various files pointed to through links),
while simultaneously running 'fs flushvol' on the volume containing the
symlinks.
The simplest way to fix this problem is to disable the use of symlink text
caching when the kernel does not provide a usable symlink API.

vmalloc-no-glock-
20070418
Based on Chris Wing's analysis which stated in part:
GFP_NOFS tells the allocator not to recurse back into the filesystem if it's
necessary to free up memory. However, vmalloc() does not have such an
option. Therefore, calling osi_Alloc() to request more than a page of
memory may end up recursing back into AFS to try to free unused inodes or
dentries.
In this case, what happened was that osi_Alloc() is called within an
AFS_GLOCK(); osi_Alloc() calls vmalloc() which tries to free dentry objects,
which then calls back into the AFS module. Unfortunately, AFS_GLOCK() is
already held and we deadlock.

windows-afskfw-bluescreen-
20070418
The afskfw library contains an unprotected call to krb5_free_context
which can result in krb5_free_context being called with a NULL pointer.
MIT's Kerberos libraries do not check that the pointer is non-NULL and
will attempt to use it as a valid pointer which will in turn result
in an invalid memory access error.
This library is used by afslogon.dll which is loaded by winlogon.exe.
If the krb5 profile is invalid, the krb5_init_context call will fail
to allocate a krb5_context structure which can then result in
krb5_free_context being called with a NULL pointer.
An unhandled exception within winlogon.exe will cause a blue screen event
on Windows 2000, XP and 2003.

windows-afslogon-
20070328
There are two serious problems with integrated logon:
(1) openafs afslogon.dll obtains Kerberos v5 tickets and then forwards them
into the logon session. This was done because MIT KFW did not have
such functionality. As of KFW 3.1, KFW does, so we are removing it.
the functionality worked by copying the credentials to a FILE ccache
and then using the Logon Event Handler to move the credentials into
an API ccache and delete the temporary file. For non-interactive
logons the Logon Event handlers do not get triggered. Neither do
LogonScripts get executed. As a side effect, for each logon a
credential cache file was left behind.
(2) when combined with non-interactive logons, there are some very bad
side effects if a network provider performs Kerberos v5 operations.
Each logon occurs in a new logon session and will spawn a private
copy of krbcc32s.exe.
As a result, integrated logon is being disabled for non-interactive
logons.
