12 years agoafs: Clear VHardMount on ResetVolumeInfo
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.

12 years agorx: Make CALL_RELE and CALL_HOLD lock refcnt mutex
Simon Wilkinson [Sun, 20 Nov 2011 23:11:53 +0000]
rx: Make CALL_RELE and CALL_HOLD lock refcnt mutex

The reference count mutex must always be held when calling CALL_RELE
or CALL_HOLD. Instead of requiring that the caller obtain, and release
the mutex, do so within the HOLD and RELE macros, greatly simplifying
calling code. Provide CALL_RELE_R and CALL_HOLD_R as versions of these
macros which can be used by callers who already hold the reference
count mutex for other purposes.

12 years agoFBSD: switch afsi_SetServerIPRank implementation
Ben Kaduk [Sat, 3 Dec 2011 19:37:09 +0000]
FBSD: switch afsi_SetServerIPRank implementation

Upstream has removed the ia_net{,mask} elements from
struct in_ifaddr, so we can no longer use them directly.
Switch to passing an rx_ifaddr_t (i.e. struct ifaddr*) in instead,
as that uses a slightly different codepath which still works
for our purposes.

We compile the kernel module with -Werror, so storing a pointer
(memcpy return value) in an int is forbidden, hence the conditional
declaration of 't'.

12 years agoWindows: buf_CleanAsync is not async; rename it
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.

integrated logon without configuring the cell, CellServDB,
installing Kerberos v5 and configuring krb5.conf can result
in a very long wait at logon.  Now that NSIS is no longer
being supported and cannot be supported as a native 64-bit
installer mechanism we must disable integrated logon by
default to prevent more bad end user experiences like

12 years agorx: Use a red black tree for the event stack

rx: Use a red black tree for the event stack

Instead of the current event stack, which uses a sorted linked
list, use a red/black tree to maintain the timer stack. This
dramatically improves event insertion times, at the expense of
some additional implementation complexity.

This change also adds reference counting to the rxevent
structure. We've always had a race between an event being
fired, and that event being simultaneously cancelled by
the user thread. Reference counting avoids that race resulting
in the structure appearing twice in the free list.

Ben Kaduk [Sun, 13 Nov 2011 18:12:50 +0000]
FBSD: cleanup dvp locking for ISDOTDOT

This is a more correct version of
c2ed2577f9c16df3088158fb593d7aab6e8690d0, which was reverted since
it caused build issues on some versions and kernel panics on others.

We do want to always unlock dvp before calling over the network
in the ISDOTDOT case, but be sure to use the proper spelling
for this operation (as the syntax has changed between FreeBSD versions).
This requires not unlocking dvp right after the afs_lookup() call if
it succeeds, letting us just lock the "child" vp (which is actually
the parent starting from '/') first, and then re-lock dvp.

The error case of afs_lookup() was already handled correctly in
this logic, which is to say that it was incorrect before this change,
attempting to recursively lock dvp which causes a panic.

Windows: _._AFS_IOCTL_._ size is zero

When replying to a FileStandardInformation query on the pioctl
special file, the size of the file is 0.  Failure to return 0
can result in an anti-virus program attempting to read the file
via a paging request which will fail.

12 years agoopr: Add Bob Jenkins's hash functions
Simon Wilkinson [Sun, 20 Nov 2011 23:40:51 +0000]
opr: Add Bob Jenkins's hash functions

This imports a small subset of Bob Jenkins lookup3.c hash functions
into the opr library. At present we only import the subset of this
that deals with aligned arrays of integers, as this addresses our
immediate need.

It seems likely that if we're interested in a hash function for string
arrays (or other arbitrary data), that more recent functions such like
SpookyHash (from Bob Jenkins, again) or CityHash (from Google) may be
a better solution.

The immediate use case for this is removing the use of the '%' operator
when indexing speed critical hash tables, as well as ensuring fairer
distribution of entries across these tables.

A short set of test cases is also provided

afs: Leave cellnum alone for explicit mtpt cell

When a mountpoint is given an explicit cell, don't alter cellnum.
Cellnum represents the cell for the parent, and is used for
determining whether or not we're crossing a cell boundary.

Previously, this code forced the mount point to always be treated as
foreign (for a mountpoint prefixed with a cell name), or to always be
treated as local (for a mountpoint prefixed with a cell number).
