VMWare adapters have proven unreliable replacements for the Microsoft
loopback adapter. Registering AFS often results in a name space collision.
Add cm_DumpCells() function and dump the cells as part of "fs memdump"
Dump all cm_scache_t and cm_volume_t regardless of reference counts
Fix cm_GetCell_Gen() to not allocate a new cm_cell_t when evaluating
mount points to aliases. Instead, after looking up the alias successfully
search the allCellsp list for the fullname of the cell. If found, use
the existing entry and cleanup the one we were about to allocate.
Use read locks whenever possible instead of write locks when searching
the allCellsp list.

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.

When the system's IP address list changes we invalidate the existing
RX connections and probe all of the servers. A better algorithm is
to probe all vldb servers, invalidate the rx connections, and then
probe all file servers.

Access to AFS volumes via magic share names
\\afs\<cell><type><volume>
<cell> = cellname
<type> = % or #
<volume> = volume name or id
(cherry picked from commit 5ac7a7db9a)
* re-write cm_Analyze to make better use of the known volume
status. VL_Server queries cannot result in CM_ERROR_ALLOFFLINE
messages.
* renamed cm_CheckBusyVolumes to cm_CheckOfflineVolumes.
busy volumes will be reset to srv_non_busy by the function
but there is no mechanism for querying the busy state other
than by attempting to access the resource.
* cm_Analyze will query the state of an offline volume before
deciding whether or not to retry when all volume instances
are offline.

1 - task_struct loses thread_info, which is now accessible through the
task_thread_info() macro. A configure test is added to deal with this.
2 - the SLAB_CTOR_VERIFY flag is gone
(cherry picked from commit 37a0b14e01)
* 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.

Do not return access denied when applying directory patches if the
