Jeffrey Altman [Tue, 27 Dec 2011 01:51:33 +0000]
Windows: add osi_TWaitExt(), fix osi_TWait()

osi_TWait() was adding new locks to the turnstile at the tail
which is the end of the queue locks are removed from.  This
implemented LIFO instead of FIFO when FIFO is the "fair" order
to service lock requests.

osi_TWaitExt() is added to permit the Reader to Writer upgrade
request to use LIFO when more than one reader is present.

12 years agoafs: Do not always ignore errors in afs_GetDSlot
Andrew Deason [Wed, 21 Dec 2011 20:04:32 +0000]
afs: Do not always ignore errors in afs_GetDSlot

Currently afs_UFSGetDSlot will silently swallow any error in reading
the specified dslot from disk, and will return a "blank" dcache to the
caller. However, many callers of afs_GetDSlot will be asking for a
dcache that we know exists, and more importantly, we know is on the
global hash table. If a disk error is encountered and we're given a
"blank" dcache, we will erroneously believe the dcache entry is not on
the hash table, causing corruption of the hash table later on.

So instead, modify all callers of afs_GetDSlot to use either
afs_GetValidDSlot or afs_GetNewDSlot. Calling afs_GetValidDSlot
indicates that the given dentry index is known to be valid, and any
error encountered while reading the entry from disk should result in
an error (for disk I/O errors we have no control over, this results in
a NULL dentry returned; for internal consistency errors we panic).
Calling afs_GetNewDSlot indicates that the specified index may not
exist or may not be valid, and so returning a "blank" dentry in that
case is fine.

For memcache, the situation is the same, except any time we go to
"disk" it is an (internal) error, since there is no disk.

12 years agoafsd: Parse cacheinfo during argument parsing
Andrew Deason [Thu, 22 Dec 2011 03:00:12 +0000]
afsd: Parse cacheinfo during argument parsing

Currently we parse cacheinfo in afsd_run, when the client is
initialized and started. Parsing cacheinfo can change
afsd_cacheMountDir, however, which may be of interest to afsd.o users;
in particular, libuafs exposes this via uafs_MountDir(). This means
that if a mount dir is not explicitly specified in the libcmd
arguments to afsd, a libuafs-using program will see the mountpoint as
the empty string if it is queried after afsd_parse but before
afsd_run. For afsd.fuse, this causes the cryptic error message:

    fuse: bad mount point `': No such file or directory

since the mountpoint is the empty string if it is not specified
explicitly on the command line.

To fix this, move cacheinfo parsing to effectively near the end of
afsd_parse, so the mountpoint is calculated in afsd_parse().

12 years agoWindows: Use AuthGroups for extent request error reporting
Jeffrey Altman [Thu, 22 Dec 2011 02:17:33 +0000]
Windows: Use AuthGroups for extent request error reporting

The afs redirector current tracks the most recent extent error
in the File Control Block.  Prior to this patchset the error
was returned to the requesting thread when the process Id matched
the most recent Process to issue a request.  This approach resulted
in a couple of problems.

 1. There are multiple threads that can issue an extent request
    on the same file at the same time representing different processes.
    Resetting the process Id with each new request could clear the
    error prior to its receipt.

 2. The failure may be due to inappropriate permissions.  Permissions
    are not associated with proceses but with Authentication Groups.

This patchset makes several changes:

 1. It enables the afsd_service to track the active authgroup as
    part of the cm_user_t structure and associates that object with
    the BIOD object to ensure that the active authgroup can be
    reported to the afs redirector.

 2. It modifies the AFSExtentFailureCB structure to include the
    AuthGroup GUID.

 3. It tracks the AuthGroup GUID associated with the extent
    failure in the non-paged file control block.

 4. It converts all tests on Process Id to use AuthGroup instead.

 5. It alters the behavior of error delivery such that reported
    error is only cleared after it has been reported once to a
    thread using the matching AuthGroup.

These changes make the situation better but not perfect as error
states can still be lost.  However, it avoids the case most often
seen in production where two processes (a end user process and an
anti-malware process) are fighting over a file and the anti-malware

12 years agoWindows: Explicit permission check on extent release
Jeffrey Altman [Thu, 22 Dec 2011 02:10:45 +0000]
Windows: Explicit permission check on extent release

When a data extent is released by the afs redirector or the
afsd_service performs an extent claw back during a cleanup
operation, perform an explicit permission check before attempting
to store dirty buffers to the file server.   Instead of waiting
for the file server to fail the request, fail it immediately.

The permission check is performed using the currently active
authentication group.

the Fcb ends up with the AuthGroup set to the anti-virus value
and not the one that belongs to the writing application.

Tracking the AuthGroup by Ccb provides the ability to select

Andrew Deason [Wed, 14 Dec 2011 20:42:08 +0000]
afs: Clear VHardMount on ResetVolumeInfo

afs_Analyze sets VHardMount on a volume struct when a hard-mount
scenario is encountered, and clears it after sleeping. However, if the
volume struct has VRecheck set, or if it's not in memory, afs_Analyze
cannot retrieve the volume struct in order to clear VHardMount again.

For the VRecheck case, this can results in VHardMount never getting
cleared, and so hard-mount messages for the volume seem to disappear.
So, clear VHardMount when we set VRecheck so this does not occur.

For the case where the volume struct is not in memory, this is not a
problem, since when we allocate a volume struct again, the VHardMount
state will not be retained.

Jeffrey Altman [Fri, 9 Dec 2011 23:40:42 +0000]
Windows: Suspend/Resume for afsd_service

The power mgmt events are received in the service.  The service
can block all requests from the redirector from being processed
until it knows that it is safe to process them.

The service will receive a SERVICE_CONTROL_APMSUSPEND just before
the system goes to sleep.  The service has two seconds to respond
and it uses that time to attempt to send RXAFS_GiveUpAllCallBacks
to all file servers as an rx_multi with no wait.  It also marks
all servers down and updates the callback expirations to be just
after the servers were marked down so that they will be forced to
be refreshed when the server is marked up.

Upon resume the service receives two events.  First,
SERVICE_CONTROL_APMRESUMEAUTOMATIC which is used to perform an
SMB lan adapter change detection and perform a probe of all down
servers.  The second, SERVICE_CONTROL_APMRESUMESUSPEND is used to
resume SMB listeners, perform a 2nd lan adapter change check (just
in case), check the status of all down servers in additional
networks have come up, and finally resume processing of redirector
requests.

With these changes no special logic in the redirector is required.

12 years agoWindows: increase timeout for extent request retries
Jeffrey Altman [Thu, 8 Dec 2011 15:00:57 +0000]
Windows: increase timeout for extent request retries

The AFS Redirector requests file data extents from the afsd_service.exe.  If
it does not receive the requested extent within 10 seconds it issues another
request for that extent.  Extent processing in the afsd_service is handled
by background daemons that process tasks serially from a work queue.   When
the load on the system is large enough that satisfying the work queue takes
longer than 10 seconds, the redirector would retry the request.  This would
increase the length of the work queue and increase lock contention.

Increasing the timeout period for extent retries to two minutes
significantly reduces the number of retry attempts while maintaining
protection against a lost extent request.  Two minutes is selected because
that is the rx hard dead call timeout.

The link table needs to be created with the VG id or RW vol id, not
the non-RW vol id. Unlike other special inodes, this goes for both the

there is only one link table per VG.

Without this, the salvager can generate invalid linktable special
inodes if it encounters a VG with no inodes for the RW vol.

DAFS: Do not transition to ERROR on trivial errors

attach2 can result in many different errors; some indicate that the
volume is in an inconsistent state, but many others just indicate that
the volume cannot be attached for benign reasons (such as VNOVOL if
the volume doesn't exist, or VOFFLINE if the volume is being used by a
volume utility). Currently, for DAFS, attach2 transitions the relevant
volume to the VOL_STATE_ERROR state for almost all errors encountered,
even the benign ones. Instead, skip the error state transition for
error handling paths that do not reflect a "broken" volume.

Windows: buf_GetNewLocked should use cleaned cm_buf

buf_GetNewLocked() searches the free buffer list for a buffer
that has a 0 refcnt, is not in the chunk that is being populated,
is not actively having I/O performed on it and is not dirty.
If it comes across a dirty buffer, it calls buf_Clean() with
the assumption that buf_CleanAsync() (as it was previously called)
was in fact asynchronous and would return immediately.  Instead
buf_Clean() is synchronous and when it completes the buffer will
in most cases be clean.  buf_GetNewLocked() should use the newly
cleaned buffer if it is still available and not continue the
search from the next entry in the free buffer list.

Jeffrey Altman [Fri, 2 Dec 2011 16:14:11 +0000]
Windows: buf_CleanAsync is not async; rename it

buf_CleanAsync() calls cm_BufWrite() which stores the dirty
buffers synchronously.  There is nothing asynchronous about
buf_CleanAsync() so rename it to buf_Clean() and buf_CleanAsyncLocked()
to buf_CleanLocked().   Update the comments to remove the references
to the asynchronous processing which doesn't exist.

That is not to say that the call to buf_Clean() in buf_GetNewLocked()
should not be asynchronous; it should.  There is no such functionality
at the moment.  One approach would be to modify buf_IncrSyncer to
trigger on an event set by buf_GetNewLocked() instead of the call
to buf_Clean().  Another approach would be registering a background
store event.  In any case, that is for another patchset.
