minimize the number of RPCs sent to the file server. only request

we do not already have status for the object

not so much that it exceeds the RDR timeout

define DEBUG_SMB_REFCOUNT in smb.h to activate refcount debugging
versions of the functions that log the file and line number as
well as object and refcount. This is for use in debugging refcount
leaks.
rename GetPacket and GetNCB to smb_GetPacket and smb_GetNCB, etc.,
to enforce the name space. Do not confuse with similar Win32 API
functions.
restructure some code that refers to smb_vc_t references in order
to clarify where the refcount is dropped.

deltas windows-smb-dead-vc-gc-20080627 and
windows-dead-vc-cleanup-take-two-20080703 attempted to
protect against an infinite recursion when cleaning up
dead smb virtual circuits. they failed to address the
incrementing of the vc refcount in smb_ReleaseVCInternal
when it is about to call smb_CleanupDeadVC. If the vc
is already being cleaned, then smb_ReleaseVCInternal
should not increment the refCount and should not call
smb_CleanupDeadVC.
(This commit was committed incorrectly to the 1-5
branch first. delta name on the head was modified
to avoid the delta name collision.)

validate the specified volume to make sure it exists before permitting
the mount point to be created. This will catch many instances in which
the user swaps the parameters to "fs mkmount".

When recycling cm_volume_t objects, avoid a race condition that could
result in the same cm_volume_t object being recycling simultaneously
in two threads. The end result would be a reference count miscount
and an undercount assertion being thrown.

When an error such as access denied, out of space, out of quota,
invalid fid, etc. is received while writing a dirty buffer to the
file server, apply that error code to all outstanding dirty buffers
immediately instead of attempting to write each buffer to the file
server only to obtain the same error.

as part of the restructuring of code to separate the smb layer
from the cm layer, large file support was broken. Define AFS_LARGEFILES
in the right place so that it will be used in the cm.

The ioctl-prefix-data can be accessed either via a char_t or a wchar_t.
Copy the data buffer with memcpy() and not strcpy() because we need to
copy the entire string if it happens to be Unicode.

Everytime the CM_BUF_DIRTY flag is set on a cm_buf_t, the userp field
on the cm_buf_t must also be set. Add a cm_user_t parameter to buf_SetDirty()
so that each function that calls it doesn't have to manually set the
last write user. This improves code readability and the abstraction layering.
LICENSE MIT
Extend the cm_MakeDir() function signature to permit the (optional)
return of the cm_scache_t object that was created by the operation
in the same way that cm_Create() does.
Make the return of the cm_scache_t by cm_Create() optional although
it is never used that way.
In both cm_Create() and cm_MakeDir() avoid releasing the cm_scache_t
object until we are actually finished with it.
LICENSE MIT
Add smb_InitReq() calls cm_InitReq() and then sets the new
CM_REQ_SOURCE_SMB flag. When this flag is set, the source of the
request is known to be the SMB interface. This flag will not be
set on requests generated by the various background daemons.
LICENSE MIT
When updating the volume location information, if a new server must
be allocated and the server is down, then it is possible for a deadlock
to occur on the cm_volume_t rw lock. Prevent that from happening.

convert additional 'connp' instances to 'rxconnp'
in cm_volume.c, make sure that we hold a reference to the rxconnp
whenever we use it to perform an RPC.

There has been long time confusion in the windows cache manager because
there are cm_conn object ptrs call connp and rx_connection object ptrs
call connp and rx_call object ptrs called callp and rx_connection object
ptrs called callp.
From now on, rxconnp is a ptr to an rx_connection object;
rxcallp is a ptr to an rx_call object; and connp is a ptr to an
cm_conn object.

During cm_InitVolume() clear CM_VOLUMEFLAG_UPDATING_VL if we are reusing
the cache data just in case.
In cm_UpdateVolumeLocation() add trace logging to the sleeping, waking,
and awaking states; move the destruction of the old server list into
the region protected by the CM_VOLUMEFLAG_UPDATING_VL flag.
LICENSE MIT
When calling ctime on an afs_int32, always use a wrapper that assigns the
variable to a time_t before passing it in rather than conditionally doing
so on hosts with a large time_t. This eliminates a configure test,
removes a bunch of warnings in vos.c on platforms with 32-bit time_t, and
will make no difference in generated code with any decent compiler.
LICENSE BSD
Everywhere AFS_PTHREAD_ENV was defined, UBIK_PTHREAD_ENV was defined as
well, so don't make them separate. Building pthreaded Ubik is controlled
by deciding whether to build the t* versions of various directories, not
by the preprocessor directives. AFS_PTHREAD_ENV is only defined when
building in those directories.
This change eliminates UBIK_PTHREAD_ENV and uses AFS_PTHREAD_ENV to mean
the same thing.
As a side effect, fixes compiles on arm with --enable-pthreaded-ubik, since
arm never defined UBIK_PTHREAD_ENV.

If during volume location updating, the VL_GetAddrsU call fails for any

No longer set the rx_SetConnDeadTime and rx_SetConnHardDeadTime to
the remaining request SMB RDR timeout within cm_ConnByMServers().
There are not per-call timeouts so simultaneous requests on the same
connection will race with each other either resulting in premature
timeouts or significantly extended timeouts.

The volume state is perfectly consistent. FSYNC_NEEDVOLUME (and the
other state in the pending_vol_op object) is perfectly normal -- it
simply means the volser has exclusive access to the volume for the
purposes of cloning. The bug is that during the DAFS development, I
changed the semantics of the VGetVolume interface without updating the
control logic in afsfileprocs accordingly:
In 1_4_x:
vp->specialstatus != 0 results in returning vp with nUsers incremented
and *ec = vp->sepcialstatus
In DAFS:
V_AttachState(vp) == VOL_STATE_UNATTACHED results in returning a NULL
vp. Since (vp->specialstatus != 0), *ec = vp->specialstatus.
The net result is we need to modify the VBUSY logic in CheckVnode().
