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().

By default, fuse mountpoints are only accessible by the same uid as

Windows: Avoid bottleneck on VolumeLock
The VolumeLock resource was obtained during each AFSParseName()
and held across a wide range of operations including volume
info queries, renames, and extent requests. These operations can
take a long time to complete and as long as the VolumeLock was
held exclusively there could only be one operation in flight at
a time on a given volume. This significantly reduced the parallelism
of operations.
The VolumeLock was not required in almost all cases. This patchset
adjusts the use of the VolumeLock and avoids the bottleneck.

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
process has no permission to access the file under its own credentials.

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.

viced: Yell when we GetSomeSpace_r
A GetSomeSpace_r call indicates we don't have enough callbacks
configured. For many people, this can happen without the administrator
realizing anything is wrong, since we never give any indication that
something is amiss, unless the administrator checks the xstat
statistics.
Since this can indicate a serious performance problem, yell in the log
when this happens. Only do it once, so we don't spam the log.

cs_CZ localization cannot be committed to the repository until:
1. Resource DLLs for all components are built in the tree.
2. All built components have been successfully tested so that OpenAFS is not shipping code that caused executable components to crash in the cs_CZ locale.

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.

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.

rx: Refactor MaxMTU error checking
The error checking on the rxMaxMTU parameter was done individually by
every server that sets it, using "internal" RX #defines to do so.
Instead, do the error checking within the function that actually sets
the MTU, reducing both the amount of code duplication, and the amount
of RX knowledge held within the servers.

salvager: Create link table with volume group id
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
'parent' and 'volume' volume ids, not just the 'parent' id, since
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.

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.
