Windows: AFSVolumeCB track RefCount reasons

Introduct AFSVolumeIncrement and AFSVolumeDecrement functions
which are used to increment not only the AFSVolumeCB.VolumeReferenceCount
but also a new VolumeReferences[Reason] counter.  In the future when
a VolumeReferenceCount error occurs it may be possible to isolate the
cause to a subset of the code.

In the process, the VolumeReferenceCount necessary to free the
AFSVolumeCB object is changed from 1 to 0 and AFSInitVolume no longer
initializes the AFSVolumeCB count to 2.

The signature for AFSInitVolume and AFSLocateNameEntry are modified
to permit a volume reference reason to be provided.  This permits
the reference to be allocated in one function and released in another
without resulting in count imbalances.

8 years agodafs: preattach should wait for exclusive states
Mark Vitale [Fri, 21 Dec 2012 22:56:14 +0000]
dafs: preattach should wait for exclusive states

In rare circumstances an FSYNC_VOL_ON operation may fail silently,
leaving the volume in its previous state.  The only clue is a FileLog
message "volume <nnnn> not in quiescent state".

This is caused by a race condition in the volume package: an
FSYNC_VOL_ON operation is attempting to preattach a volume
(in VPreAttachVolumeByVp_r()) at the same time a fileserver RPC
(e.g. FetchStatus) is detaching the volume (in VReleaseVolumeHandles_r())
at the conclusion of attach2() logic.

The fix calls VWaitExclusiveState_r() before calling
VPreAttachVolumeByVp_r().

was purged from the tree and replaced with a more complete
implementation based upon the Kernel Drivers's File System
framework rawops.c was left behind.

Although the source file has been compiled as part of the build,
its functions ReadData and WriteData have never been called.  This
patchset:

 1. renames the functions to raw_ReadData and raw_WriteData

 2. modifies the function signatures and provides a header
    with prototypes

 3. requires that cm_scache.rw be write-locked upon entry

 4. renames variables

 5. removes the #define CM_BUF_BUFSIZE and relies upon
    cm_data.blockSize instead

 6. Always write back the current range as an async store
    instead of the previous chunk as random write patterns
    will fail to store all of the dirty buffers.

Jeffrey Altman [Wed, 19 Dec 2012 21:52:34 +0000]
Windows: Disable hard dead timeout for RDR File Server connections

The UNIX cache manager does not implement hard dead timeouts
on file server connections.  The Windows cache manager had to
because of the SMB connection timeout requirements.  For the
AFS redirector there is no timeout requirement.  Therefore,
when the SMB stack is disabled the Windows cache manager can
disable the hard dead timeout.

The idle dead timeouts are in place to cancel connections when
file servers stop replying with real data.

handling.  Now that every AFSCcb is given a refCount in AFSInitCcb()

call sequences.

Wherever possible releasing of DirOpenReferenceCounts occur in a
functions try_exit block.  AFSCommonCreate() uses the new variables
bReleaseDir and bReleaseParentDir to track whether these refcounts
need to be released.  Additional comments document the decision
making.

There was at least one code path in AFSLocateNameEntry() where
the DirOpenReferenceCount could be dropped when it should not have
been. (pExistingDirNode == pDirNode).

When we get a IOCTL_AFS_GET_TRACE_BUFFER, a IOCTL_AFS_CONFIGURE_DEBUG_TRACE

NOTE that this does not check whether the user has done the "run as admin"
thing.  We actually need to determine which priviledges are appropriate to
this action and use that rather than group membership to police these actions
and this will be added in a later patch.  Meanwhile this represents a

Improve libroken configure check

It is not sufficient to just check if libroken is available; we need
to check if the specific functionality we want is there. So, try to
compile and link while referencing specific functions.

As mentioned in the comments, testing every single function we use may
not be practical, and we should perhaps just add functions to test as
we find breakage. This commit tests rk_rename, which is missing in at
least the Debian package heimdal-dev, version
1.4.0~git20100726.dfsg.1-2+squeeze1.

8 years agoOpenBSD: Add support for missing routine memmove() in kernel.
Antoine Verheijen [Mon, 21 Jan 2013 08:48:01 +0000]
OpenBSD: Add support for missing routine memmove() in kernel.

OpenBSD does not have the memmove() routine available to dynamically
loaded modules in its kernel. It exists but is not exported so it
winds up "mia" on dynamic load of the kernel module. It's needed for
the Heimdal code that's been added into OpenAFS. This patch deals
with this issue by creating an inline version in the OS-specific
param.h file.

Note that this issue does not seem to exist in the amd64 version of
OpenBSD so (at least for now) tis fix is only applied to the i386
version of the header files.

Antoine Verheijen [Mon, 21 Jan 2013 06:27:02 +0000]
OpenBSD 4.6/4.7: Define curproc for rx_atomic.h.

For OpenBSD 4.6 and 4.7, the rx_atomic.h header ultimately resorts
to the use of the default atomic routines that rely on MUTEX
macros. Those macros require that 'curproc' be defined, which in
turn requires the presence of the 'sys/proc.h' header. This patch
inserts that header into the param.h file for those systems.

Note that subsequent versions of OpenBSD have __sync_fetch_and_add
and don't require 'curproc' as a result.
