Hi folks,

This is an update of the previous patches I sent here:

http://oss.sgi.com/pipermail/xfs/2013-September/030390.html
http://oss.sgi.com/pipermail/xfs/2013-September/030398.html

I've addressed the review comments from Eric, Ben and Christoph
and fixed the non-debug build failure that Michael Semon reported.

Removing an inode from the namespace involves removing the directory
entry and dropping the link count on the inode. Removing the
directory entry can result in locking an AGF (directory blocks were
freed) and removing a link count can result in placing the inode on
an unlinked list which results in locking an AGI.

The big problem here is that we have an ordering constraint on AGF
and AGI locking - inode allocation locks the AGI, then can allocate
a new extent for new inodes, locking the AGF after the AGI.
Similarly, freeing the inode removes the inode from the unlinked
list, requiring that we lock the AGI first, and then freeing the
inode can result in an inode chunk being freed and hence freeing
disk space requiring that we lock an AGF.

Hence the ordering that is imposed by other parts of the code is AGI
before AGF. This means we cannot remove the directory entry before
we drop the inode reference count and put it on the unlinked list as
this results in a lock order of AGF then AGI, and this can deadlock
against inode allocation and freeing. Therefore we must drop the
link counts before we remove the directory entry.

This is still safe from a transactional point of view - it is not
until we get to xfs_bmap_finish() that we have the possibility of
multiple transactions in this operation. Hence as long as we remove
the directory entry and drop the link count in the first transaction
of the remove operation, there are no transactional constraints on
the ordering here.

Change the ordering of the operations in the xfs_remove() function
to align the ordering of AGI and AGF locking to match that of the
rest of the code.

Michael L Semon reported that generic/069 runtime increased on v5
superblocks by 100% compared to v4 superblocks. his perf-based
analysis pointed directly at the timestamp updates being done by the
write path in this workload. The append writers are doing 4-byte
writes, so there are lots of timestamp updates occurring.

The thing is, they aren't being triggered by timestamp changes -
they are being triggered by the inode change counter needing to be
updated. That is, every write(2) system call needs to bump the inode
version count, and it does that through the timestamp update
mechanism. Hence for v5 filesystems, test generic/069 is running 3
orders of magnitude more timestmap update transactions on v5
filesystems due to the fact it does a huge number of *4 byte*
write(2) calls.

This isn't a real world scenario we really need to address - anyone
doing such sequential IO should be using fwrite(3), not write(2).
i.e. fwrite(3) buffers the writes in userspace to minimise the
number of write(2) syscalls, and the problem goes away.

However, there is a small change we can make to improve the
situation - removing the expensive lock operation on the change
counter update.  All inode version counter changes in XFS occur
under the ip->i_ilock during a transaction, and therefore we
don't actually need the spin lock that provides exclusive access to
it through inc_inode_iversion().

Hence avoid the lock and just open code the increment ourselves when
logging the inode.

Recent analysis of a deadlocked XFS filesystem from a kernel
crash dump indicated that the filesystem was stuck waiting for log
space. The short story of the hang on the RHEL6 kernel is this:

	- the tail of the log is pinned by an inode
	- the inode has been pushed by the xfsaild
	- the inode has been flushed to it's backing buffer and is
	  currently flush locked and hence waiting for backing
	  buffer IO to complete and remove it from the AIL
	- the backing buffer is marked for write - it is on the
	  delayed write queue
	- the inode buffer has been modified directly and logged
	  recently due to unlinked inode list modification
	- the backing buffer is pinned in memory as it is in the
	  active CIL context.
	- the xfsbufd won't start buffer writeback because it is
	  pinned
	- xfssyncd won't force the log because it sees the log as
	  needing to be covered and hence wants to issue a dummy
	  transaction to move the log covering state machine along.

Hence there is no trigger to force the CIL to the log and hence
unpin the inode buffer and therefore complete the inode IO, remove
it from the AIL and hence move the tail of the log along, allowing
transactions to start again.

Mainline kernels also have the same deadlock, though the signature
is slightly different - the inode buffer never reaches the delayed
write lists because xfs_buf_item_push() sees that it is pinned and
hence never adds it to the delayed write list that the xfsaild
flushes.

There are two possible solutions here. The first is to simply force
the log before trying to cover the log and so ensure that the CIL is
emptied before we try to reserve space for the dummy transaction in
the xfs_log_worker(). While this might work most of the time, it is
still racy and is no guarantee that we don't get stuck in
xfs_trans_reserve waiting for log space to come free. Hence it's not
the best way to solve the problem.

The second solution is to modify xfs_log_need_covered() to be aware
of the CIL. We only should be attempting to cover the log if there
is no current activity in the log - covering the log is the process
of ensuring that the head and tail in the log on disk are identical
(i.e. the log is clean and at idle). Hence, by definition, if there
are items in the CIL then the log is not at idle and so we don't
need to attempt to cover it.

When we don't need to cover the log because it is active or idle, we
issue a log force from xfs_log_worker() - if the log is idle, then
this does nothing.  However, if the log is active due to there being
items in the CIL, it will force the items in the CIL to the log and
unpin them.

In the case of the above deadlock scenario, instead of
xfs_log_worker() getting stuck in xfs_trans_reserve() attempting to
cover the log, it will instead force the log, thereby unpinning the
inode buffer, allowing IO to be issued and complete and hence
removing the inode that was pinning the tail of the log from the
AIL. At that point, everything will start moving along again. i.e.
the xfs_log_worker turns back into a watchdog that can alleviate
deadlocks based around pinned items that prevent the tail of the log
from being moved...

All of the buffer operations structures are needed to be exported
for xfs_db, so move them all to a common location rather than
spreading them all over the place. They are verifying the on-disk
format, so while xfs_format.h might be a good place, it is not part
of the on disk format.

Hence we need to create a new header file that we centralise these
related definitions. Start by moving the bffer operations
structures, and then also move all the other definitions that have
crept into xfs_log_format.h and xfs_format.h as there was no other
shared header file to put them in.

From: Dave Chinner @ 2013-10-14 22:17 UTC (permalink / raw)
  To: xfs

From: Dave Chinner <dchinner@redhat.com>

The on-disk format definitions for the directory and attribute
structures are spread across 3 header files right now, only one of
which is dedicated to defining on-disk structures and their
manipulation (xfs_dir2_format.h). Pull all the format definitions
into a single header file - xfs_da_format.h - and switch all the
code over to point at that.

- * for the free bytes after the leaf_entry's, but only the N largest such,
- * smaller runs are dropped.  When the freemap doesn't show enough space
- * for an allocation, we compact the name/value area and try again.  If we
- * still don't have enough space, then we have to split the block.  The

- * nodes until the hash key changes or the attribute name is found.
- *
- * We store the fact that an attribute is a ROOT/USER/SECURE attribute in
- * the leaf_entry.  The namespaces are independent only because we also look
- * at the namespace bit when we are looking for a matching attribute name.
- *
- * We also store an "incomplete" bit in the leaf_entry.  It shows that an
- * attribute is in the middle of being created and should not be shown to
- * the user if we crash during the time that the bit is set.  We clear the
- * bit when we have finished setting up the attribute.  We do this because

+ *========================================================================
+ * Attribute structure when equal to XFS_LBSIZE(mp) bytes.
+ *========================================================================
+ *
+ * Struct leaf_entry's are packed from the top.  Name/values grow from the
+ * bottom but are not packed.  The freemap contains run-length-encoded entries
+ * for the free bytes after the leaf_entry's, but only the N largest such,
+ * smaller runs are dropped.  When the freemap doesn't show enough space
+ * for an allocation, we compact the name/value area and try again.  If we
+ * still don't have enough space, then we have to split the block.  The
+ * name/value structs (both local and remote versions) must be 32bit aligned.
+ *
+ * Since we have duplicate hash keys, for each key that matches, compare
+ * the actual name string.  The root and intermediate node search always
+ * takes the first-in-the-block key match found, so we should only have
+ * to work "forw"ard.  If none matches, continue with the "forw"ard leaf
+ * nodes until the hash key changes or the attribute name is found.
+ *
+ * We store the fact that an attribute is a ROOT/USER/SECURE attribute in
+ * the leaf_entry.  The namespaces are independent only because we also look
+ * at the namespace bit when we are looking for a matching attribute name.
+ *
+ * We also store an "incomplete" bit in the leaf_entry.  It shows that an
+ * attribute is in the middle of being created and should not be shown to
+ * the user if we crash during the time that the bit is set.  We clear the
+ * bit when we have finished setting up the attribute.  We do this because
+ * we cannot create some large attributes inside a single transaction, and we
+ * need some indication that we weren't finished if we crash in the middle.

- * Directory Version 3 With CRCs.
- *
- * The tree formats are the same as for version 2 directories.  The difference
- * is in the block header and dirent formats. In many cases the v3 structures
- * use v2 definitions as they are no different and this makes code sharing much
- * easier.
- *
- * Also, the xfs_dir3_*() functions handle both v2 and v3 formats - if the
- * format is v2 then they switch to the existing v2 code, or the format is v3
- * they implement the v3 functionality. This means the existing dir2 is a mix of
- * xfs_dir2/xfs_dir3 calls and functions. The xfs_dir3 functions are called
- * where there is a difference in the formats, otherwise the code is unchanged.
- *
- * Where it is possible, the code decides what to do based on the magic numbers
- * in the blocks rather than feature bits in the superblock. This means the code
- * is as independent of the external XFS code as possible as doesn't require
- * passing struct xfs_mount pointers into places where it isn't really
- * necessary.
- *
- * Version 3 includes:
- *
- *	- a larger block header for CRC and identification purposes and so the
- *	offsets of all the structures inside the blocks are different.
- *
- *	- new magic numbers to be able to detect the v2/v3 types on the fly.

  To: xfs

From: Dave Chinner <dchinner@redhat.com>

Parts of userspace want to be able to read and modify dquot buffers
(e.g. xfs_db) so we need to split out the reading and writing of
these buffers so it is easy to shared code with libxfs in userspace.

We don't do callbacks at transaction commit time, no do we have any
infrastructure to set up or run such callbacks, so remove the
variables and typedefs for these operations. If we ever need to add
callbacks, we can reintroduce the variables at that time.

From: Dave Chinner @ 2013-10-14 22:17 UTC (permalink / raw)

From: Dave Chinner <dchinner@redhat.com>

xfs_trans.h has a dependency on xfs_log.h for a couple of
structures. Most code that does transactions doesn't need to know
anything about the log, bu this dependency means that they have to
include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header
files and clean up the includes to be in dependency order.

In doing this, remove the direct include of xfs_trans_reserve.h from
xfs_trans.h so that we remove the dependency between xfs_trans.h and
xfs_mount.h. Hence the xfs_trans.h include can be moved to the
indicate the actual dependencies oher header files have on it.

Note that these are kernel only header files, so this does not
translate to any userspace changes at all.

From: Dave Chinner @ 2013-10-14 22:17 UTC (permalink / raw)
  To: xfs

From: Dave Chinner <dchinner@redhat.com>

Currently the xfs_inode.h header has a dependency on the definition
of the BMAP btree records as the inode fork includes an array of
xfs_bmbt_rec_host_t objects in it's definition.

Move all the btree format definitions from xfs_btree.h,
xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to
xfs_format.h to continue the process of centralising the on-disk
format definitions. With this done, the xfs inode definitions are no
longer dependent on btree header files.

The enables a massive culling of unnecessary includes, with close to
200 #include directives removed from the XFS kernel code base.

  To: xfs

From: Dave Chinner <dchinner@redhat.com>

xfs_rtalloc.c is partially shared with userspace. Split the file up
into two parts - one that is kernel private and the other which is
wholly shared with userspace.

From: Dave Chinner <dchinner@redhat.com>

Lots of the dir code now goes through switches to determine what is
the correct on-disk format to parse. It generally involves a
"xfs_sbversion_hasfoo" check, deferencing the superblock version and
feature fields and hence touching several cache lines per operation
in the process. Some operations do multiple checks because they nest
conditional operations and they don't pass the information in a
direct fashion between each other.

Hence, add an ops vector to the xfs_inode structure that is
configured when the inode is initialised to point to all the correct
decode and encoding operations.  This will significantly reduce the
branchiness and cacheline footprint of the directory object decoding
and encoding.

This is the first patch in a series of conversion patches. It will
introduce the ops structure, the setup of it and add the first
operation to the vector. Subsequent patches will convert directory
ops one at a time to keep the changes simple and obvious.

Just this patch shows the benefit of such an approach on code size.
Just converting the two shortform dir operations as this patch does
decreases the built binary size by ~1500 bytes:

$ size fs/xfs/xfs.o.orig fs/xfs/xfs.o.p1
   text    data     bss     dec     hex filename
 794490   96802    1096  892388   d9de4 fs/xfs/xfs.o.orig
 792986   96802    1096  890884   d9804 fs/xfs/xfs.o.p1
$

That's a significant decrease in the instruction cache footprint of
the directory code for such a simple change, and indicates that this
approach is definitely worth pursuing further.

From: Dave Chinner @ 2013-10-14 22:17 UTC (permalink / raw)
  To: xfs

From: Dave Chinner <dchinner@redhat.com>

Following from the initial patch to introduce the directory
operations vector, convert the rest of the shortform directory
operations to use vectored ops rather than superblock feature
checks. This further reduces the size of the built binary:

   text    data     bss     dec     hex filename

From: Dave Chinner <dchinner@redhat.com>

Following from the initial patches to vectorise the shortform
directory encode/decode operations, convert half the data block
operations to use the vector. The rest will be done in a second
patch.

This further reduces the size of the built binary:

From: Dave Chinner <dchinner@redhat.com>

Convert the rest of the directory data block encode/decode
operations to vector format.

This further reduces the size of the built binary:

Next step in the vectorisation process is the leaf block
encode/decode operations. Most of the operations on leaves are
handled by the data block vectors, so there are relatively few of
them here.

Because of all the shuffling of code and having to pass more state
to some functions, this patch doesn't directly reduce the size of
the binary. It does open up many more opportunities for factoring
and optimisation, however.

  To: xfs

The remaining non-vectorised code for the directory structure is the
node format blocks. This is shared with the attribute tree, and so
is slightly more complex to vectorise.

Introduce a "non-directory" directory ops structure that is attached
to all non-directory inodes so that attribute operations can be
vectorised for all inodes.

Once we do this, we can vectorise all the da btree operations.
Because this patch adds more infrastructure than it removes the
binary size does not decrease:

  To: xfs

From: Dave Chinner <dchinner@redhat.com>

Conversion from on-disk structures to in-core header structures
currently relies on magic number checks. If the magic number is
wrong, but one of the supported values, we do the wrong thing with
the encode/decode operation. Split these functions so that there are
discrete operations for the specific directory format we are
handling.

In doing this, move all the header encode/decode functions to
xfs_da_format.c as they are directly manipulating the on-disk
format. It should be noted that all the growth in binary size is
from xfs_da_format.c - the rest of the code actaully shrinks.

Next step in the vectorisation process is the directory free block
encode/decode operations. There are relatively few of these, though
there are quite a numberof calls to them.

Binary sizes:

From: Dave Chinner <dchinner@redhat.com>

Many of the vectorised function calls now take no parameters and
return a constant value. There is no reason for these to be vectored
functions, so convert them to constants

Binary sizes:

xfs: vectorise directory leaf operations

From: Dave Chinner <dchinner@redhat.com>

Next step in the vectorisation process is the leaf block
encode/decode operations. Most of the operations on leaves are
handled by the data block vectors, so there are relatively few of
them here.

Because of all the shuffling of code and having to pass more state
to some functions, this patch doesn't directly reduce the size of
the binary. It does open up many more opportunities for factoring
and optimisation, however.

IIRC Christoph had some concerns with this one, but it wasn't very clear
exactly what they were.  This looks ok to me.  Christoph did you have anything
more to add?

I pulled some of the btree specific definitions back into
xfs_btree.h (key, ptr unions), but I left the bmbt_rec-host
definitions in the header as I haven't worked out exactly how to
relocate them without introducing new dependencies everywhere. Hence
I've cleaned up most of what Christoph asked for, but I'm leaving
the hard part for a separate patch(set) where it will be (hopefully)
much clearer what is being moved and what dependencies it
reintroduces.

Cheers,

Dave.

Yes, please go ahead with merging it for now, we can sort out any minor

From: Dave Chinner <dchinner@redhat.com>

All of the buffer operations structures are needed to be exported
for xfs_db, so move them all to a common location rather than
spreading them all over the place. They are verifying the on-disk
format, so while xfs_format.h might be a good place, it is not part
of the on disk format.

Hence we need to create a new header file that we centralise these
related definitions. Start by moving the bffer operations
structures, and then also move all the other definitions that have
crept into xfs_log_format.h and xfs_format.h as there was no other
shared header file to put them in.

From: Dave Chinner @ 2013-10-22 23:40 UTC (permalink / raw)
  To: Ben Myers; +Cc: xfs

From: Dave Chinner <dchinner@redhat.com>

xfs_trans.h has a dependency on xfs_log.h for a couple of
structures. Most code that does transactions doesn't need to know
anything about the log, bu this dependency means that they have to
include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header
files and clean up the includes to be in dependency order.

In doing this, remove the direct include of xfs_trans_reserve.h from
xfs_trans.h so that we remove the dependency between xfs_trans.h and
xfs_mount.h. Hence the xfs_trans.h include can be moved to the
indicate the actual dependencies oher header files have on it.

Note that these are kernel only header files, so this does not
translate to any userspace changes at all.

V2: rebase due to changed fs/xfs/xfs_file.c include files as a
result of the fallocate rework.

Ignore this patch - it's a rebase for 08/19, not 09/19. I'll send
the rebase for this patch in a minute.

* [PATCH 08/19, V2] xfs: decouple log and transaction headers

From: Dave Chinner <dchinner@redhat.com>

xfs_trans.h has a dependency on xfs_log.h for a couple of
structures. Most code that does transactions doesn't need to know
anything about the log, bu this dependency means that they have to
include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header
files and clean up the includes to be in dependency order.

In doing this, remove the direct include of xfs_trans_reserve.h from
xfs_trans.h so that we remove the dependency between xfs_trans.h and
xfs_mount.h. Hence the xfs_trans.h include can be moved to the
indicate the actual dependencies oher header files have on it.

Note that these are kernel only header files, so this does not
translate to any userspace changes at all.

* [PATCH 09/19, V3] xfs: decouple inode and bmap btree header files

  To: Ben Myers; +Cc: xfs

From: Dave Chinner <dchinner@redhat.com>

Currently the xfs_inode.h header has a dependency on the definition
of the BMAP btree records as the inode fork includes an array of
xfs_bmbt_rec_host_t objects in it's definition.

Move all the btree format definitions from xfs_btree.h,
xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to
xfs_format.h to continue the process of centralising the on-disk
format definitions. With this done, the xfs inode definitions are no
longer dependent on btree header files.

The enables a massive culling of unnecessary includes, with close to
200 #include directives removed from the XFS kernel code base.

V3: rebase due to changed fs/xfs/xfs_file.c include files as a
result of the fallocate rework.

(Wrong patch sent as v2, ignore it)

Generally looks pretty good, I have a question below...

appear not to be accounting for the modified entry size due to the file
type field.  Am I missing something?

The ftype field is handled by the alignment roundup. i.e. namelen is
1 or two bytes, plus ftype is 2 or 3 bytes, roundup is to 8 bytes.
Hence adding a byte for the ftype field is not a problem for these
first entries because of their small, fixed size.

Cheers,

Dave.

It should either be explicitly correct (and I think it is today), or we need a
comment to explain why it's not.  I would prefer the former.

I should point out that this code is functionally identical to the
way the original macros treated the v4 ftype code. You reviewed that
code and tested it and it as such this implicit use of padding was
considered perfectly OK just a couple of months ago.....

Well, I'll add a patch at the end of the series to change it. I
don't want to have to rebase the rest of the patches in the series
just because of the don't apply because of context mismatches.

Besides, the last patch in the series it replaces the offset
functions with precalculated values. That replacement fixes the
offset calculation to explicitly use dir2 hdrs and dir3 entsizes, so
the problem goes away for those entries.

Cheers,

Dave.

It is a detail that I overlooked.  I try to do a thorough review... but
sometimes things don't register.

Ok, I'll look out for it then.

Ah.  Looks like it snuck into the next patch.

Other than that it looks good.

That looks like it fixes a bug introduced in one of the earlier patches.  Other
than that this looks good.

I like how . and .. offsets changed into constants.
