The function cm_SyncOp() can cause threads to wait either because there
is a state conflict on the current use of the cm_scache_t object or
a state conflict on the cm_buf_t object. Waiting is always performed
on the cm_scache_t object. However, if the conflict was with the cm_buf_t
object there was no method for waking up the thread when the conflict is
cleared. Now all of the cm_buf_t waiting functions also take a cm_scache_t
and waiting threads are woken if necessary.
cm_scache_t and cm_buf_t objects now have waitCount and waitRequest fields.
The WAITING flag is now cleared by the waking thread who sets waitCount to
zero.
Many improvements to trace logging for these issues.

a couple of more locations at which cm_SyncOpDone() either was not
called or was called without holding the scache mutex.
(cherry picked from commit 528c511aabaefcafc01361c8038766ce56fe8e45)
(1) Replace all calls to getenv() with GetEnvironment(). getenv() does
not read from the real environment but instead from a copy created by
the C RTL.
(2) Add support for preserving Kerberos 5 tickets during the Integrated
Logon process. Now when Integrated Logon is used, the tickets will
be stored into the default ccache within the user session.
(3) Stress testing at MIT uncovered two code paths that could leave
threads in a permanent sleep state under heavy load. Calls to
cm_SyncOpDone were added to plug this hole.

Add "replace_afs.cmd" file
cm_EndCallbackGrantingCall contained a race condition due to the release
of the cm_callbackLock in the middle of the for() loop. The race was
removed by optimizing out the call to cm_CallbackNotifyChange(). There
is no reason this needed to be called once per callback revoke in the
list.

or not the selected item(s) contain mount points
(cherry picked from commit 9198f00b19d0ba793d62241973403d7d1e8acfab)
Add new hooks from "AfsdHook.dll" to the afsd_service.exe
AfsdInitHook - where you currently have one
AfsdRxStartedHook - after RxInit but before SmbInit
AfsdSmbStartedHook - after SmbInit
AfsdBkDaemonHook - called by the BkDaemon thread and is executed once per
cycle
AfsdStoppingHook - called just after a shutdown event has been
received but before any shutdown has been performed
AfsdStoppedHook - called just after all shutdown operations after
completed but before the service terminates
The type of the function is
BOOL ( APIENTRY * AfsdHook )(void)
in all cases. Returning FALSE will cause the service to shutdown.

Ran more stress tests against 1.3.80b on a dual processor machine and
found a number of additional errors which could be fixed.
cm_callback.c: correct the refCount handling of server lists when
processing registering callbacks on the scache entry
cm_conn.c: cm_Analyze was not handling the CM_ERROR_NOSUCHVOLUME case.
In this case force a retry and Force Update the Volume info
cm_dcache.c; do not hold mx locks around calls to rx_NewCall(). That is
why we have reference counting on the rx_connection objects.
cm_ioctl.c: replace references to afsdcell.ini with CellServDB
cm_utils.c: formatting
cm_vnodeops.c: improve the logging and add a missing call to
cm_EndCallbackGrantingCall()
cm_volume.c: allows cm_volume_t objects to be reused if their
ref count is 0 and we have hit the maximum number allowed.
smb.c: improve the logging and the handling of dead_vcp references.
If all of the SMB sessions and NCBs are in use, return BUSY to the
CIFS client.
smb3.c: convert constants to preprocessor symbols
(cherry picked from commit b9bf7ee01acc7f2646fbc6e09c1ca8d41cc59d55)
the use logon cache hack only works on xp and above. do not give up

conditionalize the assertions on smb_vc_t refcounts as they are only

it for the 1.3.80 release.

Found another case in which the windows client could break connections
which should not be broken if cryptall is on. If the connection is
unauthenticated because there are no tokens, the connections will be
broken.
If a site relies on AFSDB records and the client machine is configured
to append a domain suffix to all queries it is possible for "foo" and
"foo.bar" to appear to be separate cells. fixed by appending a trailing
'.' to all AFSDB queries if there is not already one.

smb3.c: another fix for pattern matching. Patterns can include '<' and '>'
instead of '*' and '?'. Treat any pattern with angle bracket as
star patterns
afslogon.c: instead of retrying the username lowercased if it is all

lowercased. this captures the mixedcase username case.
afskfw.c: If Leash is configured to not import tickets from the MSLSA,
neither should we.

being held.
