Linux 4.5: don't access i_mutex directly
Linux commit 5955102c, in preparation for future work, introduced
wrapper functions to lock/unlock inode mutexes. This is to
prepare for converting it to a read-write semaphore, so that
lookup can be done with only the shared lock held.
Adopt the afs_linux_*lock_inode() functions accordingly, and
convert afs_linux_fsync() to using those wrappers, since the
FOP_FSYNC_TAKES_RANGE case appears to be the current case.
Amusingly, afs_linux_*lock_inode() already have a branch to
handle the case when inode serialization is protected by a
semaphore; it seems that this is going to come full-circle.

Linux 4.5: get_link instead of follow_link+put_link
In linux commit 6b255391, the follow_link inode operation was
replaced by the get_link operation, which is basically the same
but takes the inode and dentry separately, allowing for the

In 1.4, a 'vos backup' command looked like this:
$ vos backup root.cell -verbose

As of 1.6.1, this output now looks like this:
$ vos backup root.cell -verbose

done

Note the extra " done". This change can break scripts that parse "vos"
output, but mainly it just looks confusing and doesn't make any sense.
This extra " done" appeared in verbose output for 'vos backup', 'vos
backupsys', and 'vos clone'. It was introduced by commit 13a4f2b1,
which added a VDONE to DoVolClone. This new VDONE call does make
sense, as this does make DoVolClone more self-contained, but the old
VDONE messages were not removed, so an extra " done" got printed.
In addition, commit 13a4f2b1 introduced a new call to DoVolDelete
followed by a VDONE, even though DoVolDelete calls VDONE itself,
causing another redundant " done".
To get rid of all of these redundant " done" messages, remove some
extra VDONE calls in UV_BackupVolume and UV_CloneVolume.
Almost all other calls to VDONE in vsprocs.c are matched by a
preceding message that says what we are doing. The sole exception is
UV_ChangeLocation, which outputs a " done" without any preceding
message. However, this is the behavior that UV_ChangeLocation (and
thus 'vos changeloc') has always has since it was introduced in 0c03f860.

afs: shake harder in shake-loose-vcaches
Linux based cache managers will allocate vcaches on demand and
deallocate batches of vcaches in the background. This feature is called
dynamic vcaches.
Vcaches to be deallocated are found by traversing the vcache LRU list
(VLRU) from the oldest vcache to the newest. Up to a target number of
vcaches are attempted to be evicted. The afs_xvcache lock protecting
the VLRU may be dropped and re-acquired while attempting to evict a
vcache. When this happens, it is possible the VLRU may have changed, so
the traversal of the VLRU is restarted. This restarting of the VLRU
transversal is limited to 100 iterations to avoid looping indefinitely.
Vcaches which are busy cannot be evicted and remain in the VLRU. When a
busy cache was not evicted and the afs_xvache lock was dropped, the VLRU
traversal is restarted from the end of the VLRU. When the busy vcache is
encountered on the retry, it will trigger additional retries until the
loop limit is reached, at which point the target number of vcaches will
not be deallocated.
This can leave a very large number of unbusy vcaches which are never
deallocated. On a busy machine, tens of millions of unused vcaches can
remain in memory. When the busy vcache at the end of the VLRU is finally
evicted, the log jam is broken, and the background deamon will hold the
afs_xvcache lock for an excessively long time, hanging the system.
Fix this by moving busy vcaches to the head of the VLRU before
restarting the VLRU traversal. These busy vcaches will be skipped when
retrying the VLRU traversal, allowing the cache manager to make progress
deallocating vcaches down to the target level.
This was already done on the mac osx platform while attempting to evict
vcaches. Move the code to move busy vcaches to the head of the VLRU up
the the platform agnostic caller.
Thanks to Andrew Deason for the initial version of this patch.

Note: This crash was exposed by other bugs (to be addressed in future
commits) in OpenAFS large volume support. However, there may
be other failure paths (unrelated to large volumes) that expose
this error as well.
When VAllocVnode() must allocate a new vnode but fails while
updating the vnode index file (e.g. an "addled bitmap" due to other
bugs in working with a vnode index larger than 2^31 bytes), it branches
to common recovery logic at label error_encountered:.
Part of this recovery is to call VFreeBitmapEntry_r(). Commit 08ffe3e81d875b58ae5fe4c5733845d5132913a0 added a VOL_FREE_BITMAP_WAIT
flag to VFreeBitmapEntry() in order to prevent races with VAllocBitmapEntry().
If the caller specifies VOL_FREE_BITMAP_WAIT, VFreeBitmapEntry_r will
call VCreateReservation_r() and VWaitExclusiveState_r(). However, the
exit from VFreeBitmapEntry_r() calls VCancelReservation_r() unconditionally.
This works correctly with the majority of callers to VFreeBitmapEntry_r,
which do specify the VOL_FREE_BITMAP_WAIT flag.
However, the VAllocVnode() error_encountered logic must specify 0 for
this flag because the thread is already in an exclusive state
(VOL_STATE_VNODE_ALLOC). This correctly causes VFreeBitmapEntry_r() to
forgo both the reservation and wait-for-exclusive-state. However, before
exit it erroneously calls VCancelReservation_r(). We now have unbalanced
reservations (nWaiters); this causes an assert when the VAllocVnode()
error_encountered recovery code later calls VCancelReservation_r()
for what it believes is its own prior reservation.
Modify VFreeBitmapEntry_r() to make its final VCancelReservation_r()
conditional on flag VOL_FREE_BITMAP_WAIT.

without issues. The aforementioned issue with afs_DoPartialWrite does
not apply, since directory chunks cannot be dirty (we only locally
modify the chunk if we modify the dir on the server, and the DVs
match).

afs: Fix fetchInit for negative/large lengths
Currently, the 'length64' variable in rxfs_fetchInit is almost
completely unused (it just goes into an icl logging function). For the
length that we actually use ('*alength'), we just take the lower 32
bits of the length that the fileserver told us. This method is
incorrect in at least the following cases:
- If the fileserver returns a length that is larger than 2^32-1,
we'll just take the lower 32 bits of the 64-bit length the
fileserver told us about. The client currently never requests a
fetch larger than 2^32-1, so this would be an error, but if this
occurred, we would not detect it until much later in the fetch.
- If the fileserver returns a length that is larger than 2^31-1, but
smaller than 2^32, we'll interpret the length as negative (which we
assume is just 0, due to bugs in older fileservers). This is also
incorrect.
- If the fileserver returns a negative length smaller than -2^31+1,
we may interpret the give length as a positive value instead of a
negative one. Older fileservers can do this if we fetch data beyond
the file's EOF (this was fixed in the fileserver in commit 529d487d65d8561f5d0a43a4dc71f72b86efd975). This positive length
will cause an error (usually), instead of proceeding without error
(which is what would happen if we correctly interpreted the length
as negative).
On Solaris, this can manifest as a failed write, when writing to a
location far beyond the file's EOF from the fileserver's point of
view, because Solaris writes can trigger a fetch for the same area.
Seeking to a location far beyond the file's EOF and writing can
trigger this, as can a normal copy into AFS, if the file is large
enough and the cache is large enough. To explain in more detail:
When copying a file into AFS, the cache manager will buffer the dirty
data in the disk cache until the file is synced/closed, or we run out
of cache space. While this data is buffering, the application will
write into an offset, say, 3GiB into the file. On Solaris, this can
trigger a read for the same region, which will trigger a fetch from
the fileserver at the offset 3GiB into the file. If the fileserver
does not contain the fix in commit 529d487d65d8561f5d0a43a4dc71f72b86efd975, it will respond with a large
negative number, which we interpret as a large positive number; much
larger than the requested length. This will cause the fetch to fail,
which then causes the whole write() call to fail. Specifically this
will fail with EINVAL on Solaris, since that is the error code we
return from afs_GetOnePage when we fail to acquire a dcache. If the
cache is small enough, this will not happen, since we will flush data
to the fileserver before we have a large amount of dirty data,
e.g., 3GiB. (The actual error occurs closer to 2GiB, but this is just
for illustrative purposes.)
To fix this, detect the various ranges of values mentioned above, and
handle them specially. Lengths that are too large will yield an error,
since we cannot handle values over 2^31-1 in the rxfs_* framework
currently.
For lengths that are negative, just act as if we received a length of
0. Do this for both the 64-bit codepath and the non-64-bit codepath,
just so they remain identical.

Most of the time, this is fine. However, if 'position' is more than
2GiB greater than file_length, 'size' will calculated to be smaller
than -2GiB. Since 'size' in this code is a signed 32-bit integer, this
can cause 'size' to underflow, and result in a value closer to
(positive) 2GiB.
This has two potential effects:
The afs_AdjustSize call in afs_GetDCache will cause the underlying
cache file for this dcache to be very large (if our offset is around
2GiB larger than the file size). This can confuse other parts of the
client, since our cache usage reporting will be incorrect (and can be
even way larger than the max configured cache size).
This will also cause a read request to the fileserver that is larger
than necessary. Although 'size' will be capped at our chunksize, it
should be 0 in this situation, since we know there is no data to
fetch. At worst, this currently can just result in worse performance
in rare situations, but it can also just be very confusing.
Note that an afs_GetDCache request beyond EOF can currently happen in
non-race conditions on at least Solaris when performing a file write.

trigger the overflow in 'size' in most cases:

LINUX: don't cache negative entries for dynroot
The dynroot volume lacks any callbacks that would invalidate the directory
or change the data version. Further, the data version for the dynroot
is only updated for when a new cell is found or added (a positive lookup).

afs: do not allow two shutdown sequences in parallel
Often, ‘afsd -shutdown’ is called right after ‘umount’.
Both commands hold the glock before calling ‘afs_shutdown’.
However, one of the functions called by 'afs_shutdown', namely,
‘afs_FlushVCBs’, might drop the glock when the global
'afs_shuttingdown' is still equal to 0. As a result, a scenario
with two shutdown sequences proceeding in parallel is possible.
To fix the problem, the global ‘afs_shuttingdown’ is used as an
enumerated type to make sure that the second thread will not run
‘afs_shutdown’ while the first one is stuck inside ‘afs_FlushVCBs’.

redhat: Correct permissions on systemd unit files
Change the systemd unit file permissions created via
openafs.spec to be 0644 instead of 0755. Having the
systemd unit files be executable will trigger a systemd
warning.
