On Windows there is no chown or chgrp command that can be used to
change the owner or group of an object in AFS. Therefore we
add them to the fs command.
Usage: fs chown -owner <user name or id> [-path <dir/file path>+] [-literal] [-help]
Where: -literal literal evaluation of mountpoints and symlinks
Usage: fs chgrp -group <user/group name or id> [-path <dir/file path>+] [-literal] [-help]
Where: -literal literal evaluation of mountpoints and symlinks

Add a debug log warning if the target volume is a DFS File Set.
If so, the client will not properly protect against information
leakage or properly deal with directory name caching, symlinks,

libafsconf.dll has been present since OpenAFS 1.0. However,
for some unknown reason the components that it consists of
(cm_dns.obj, cm_config.obj, cm_nls.obj) have been staticly
linked into exes and dlls all over the code base. This commit
removes all of the static references and replaces them with
libafsconf.lib.
libafsconf.dll is also moved from Client\Program to Common
because it is now linked to by server and utility components.

cm_Link() is used to create hard links. It did not apply the updated
link target status info to the target cm_scache_t object. As a result
the linkCount would be incorrect.
cm_Unlink() did not take linkCount into account. It did not reduce the
locally known linkCount, nor did it invalidate any currently known
callback. As a result the linkCount would be incorrect.

Change the PathInAfs test to use VIOCGETFID instead of VIOC_GET_CELL_NAME.
VIOCGETFID permits a literal test of the specified object. This is needed

Change how BPlusDir enumerations behave with regards to bulk stat
operations. If the number of entries in the enumeration is larger
than the number of cm_scache objects, then using the previous model
of cm_BPlusDirEnumBulkStat being called for the entire enumeration
list results in the early objects being recycled and the status
info discarded before the caller of cm_BPlusDirNextEnumEntry()
receives the name.
The revised model triggers bulk stat operations from within
NextEnumEntry() as objects requiring status fetching are about
to be returned to the caller. This reduces the thrashing of the
stat cache.
We should consider adding a flag field to cm_BPlusDirEnumerate()
or cm_BPlusDirNextEnumEntry() to permit enumeration without
status fetching.

Unlike the unix cache manager, on Windows the server uuid was not
recorded as part of the cm_server object. This commit adds the uuid
and a flag to indicate if it is set or not.
A check is made in cm_UpdateVolumeLocation it confirm that the uuid
known to the CM is the same as the one being reported by the vl server.
If they differ, this is logged but no action is taken.
The contents of the cm_allServers list is now dumped in response to
"fs memdump" or a crash. This includes the uuid, addr, type, flags,
downtime, caps, etc.
The server uuid is not useful at the moment because there is nothing
that the CM can use it for. However, it might be useful for debugging
and it will be needed for extended callback support.

A readonly volume with multiple instances was being marked alldown
when one of the instances resulted in VNOVOL because the vldb and
the indicated file server were out of sync. The cache manager would
then attempt to re-obtain the volume location info from the vldb
for the entire timeout period.
This patch:
adds trace logging to cm_Analyze indicating which server references
are being deleted and which remain in response to a VNOVOL/VMOVED error.
adds trace logging to cm_UpdateVolumeStatusInt showing how the
new volume status value is determined.
corrects cm_Analyze() so that it doesn't corrupt the server reference
list during cm_FreeServerList() calls; doesn't orphan the server reference
list by setting *serverpp to NULL; and only re-obtains the volume info
list once per request.

* remove the cm_scache_t * from the cm_BPlusDirEnumBulkStat call
now that it is part of the cm_direnum_t object
* maintain a reference to the cm_scache_t for the life of the
cm_direnum_t object. This ensures that the object cannot be
recycled while the enumeration is in use.

which is still referring to the last symlink in the chain.

torn down.

Bring a bit more sanity to the Freelance code:
1. Add functions cm_FreelanceFetchMountPointString and
cm_FreelanceFetchFileType to cm_freelance.c. These functions
permit the MountPointString and FileType to be obtained within
cm_GetSCache without requiring knowledge of data structures
that should be private to cm_freelance.c
2. Enforce the rule that odd vnode values are directory objects.
The root directory is 1 and everything else must be a multiple
of two.
3. Use the unique field as an index into the localMountPoints
array.
4. Fix cm_GetCallback to process freelance data refreshes on
all objects in the freelance volume not just the root directory.
If this is not done, an access to \\afs\foo prior to \\afs\all
being evaluated will cause an unnecessary attempt to send a
fetch status request to a file server and produce an alldown
error.
