RCU-based dcache locking model
==============================
On many workloads, the most common operation on dcache is to look up a
dentry, given a parent dentry and the name of the child. Typically,
for every open(), stat() etc., the dentry corresponding to the
pathname will be looked up by walking the tree starting with the first
component of the pathname and using that dentry along with the next
component to look up the next level and so on. Since it is a frequent
operation for workloads like multiuser environments and web servers,
it is important to optimize this path.
Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
every component during path look-up. Since 2.5.10 onwards, fast-walk
algorithm changed this by holding the dcache_lock at the beginning and
walking as many cached path component dentries as possible. This
significantly decreases the number of acquisition of
dcache_lock. However it also increases the lock hold time
significantly and affects performance in large SMP machines. Since
2.5.62 kernel, dcache has been using a new locking model that uses RCU
to make dcache look-up lock-free.
The current dcache locking model is not very different from the
existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
protected the hash chain, d_child, d_alias, d_lru lists as well as
d_inode and several other things like mount look-up. RCU-based changes
affect only the way the hash chain is protected. For everything else
the dcache_lock must be taken for both traversing as well as
updating. The hash chain updates too take the dcache_lock. The
significant change is the way d_lookup traverses the hash chain, it
doesn't acquire the dcache_lock for this and rely on RCU to ensure
that the dentry has not been *freed*.
Dcache locking details
======================
For many multi-user workloads, open() and stat() on files are very
frequently occurring operations. Both involve walking of path names to
find the dentry corresponding to the concerned file. In 2.4 kernel,
dcache_lock was held during look-up of each path component. Contention
and cache-line bouncing of this global lock caused significant
scalability problems. With the introduction of RCU in Linux kernel,
this was worked around by making the look-up of path components during
path walking lock-free.
Safe lock-free look-up of dcache hash table
===========================================
Dcache is a complex data structure with the hash table entries also
linked together in other lists. In 2.4 kernel, dcache_lock protected
all the lists. We applied RCU only on hash chain walking. The rest of
the lists are still protected by dcache_lock. Some of the important
changes are :
1. The deletion from hash chain is done using hlist_del_rcu() macro
which doesn't initialize next pointer of the deleted dentry and
this allows us to walk safely lock-free while a deletion is
happening.
2. Insertion of a dentry into the hash table is done using
hlist_add_head_rcu() which take care of ordering the writes - the
writes to the dentry must be visible before the dentry is
inserted. This works in conjunction with hlist_for_each_rcu(),
which has since been replaced by hlist_for_each_entry_rcu(), while
walking the hash chain. The only requirement is that all
initialization to the dentry must be done before
hlist_add_head_rcu() since we don't have dcache_lock protection
while traversing the hash chain. This isn't different from the
existing code.
3. The dentry looked up without holding dcache_lock by cannot be
returned for walking if it is unhashed. It then may have a NULL
d_inode or other bogosity since RCU doesn't protect the other
fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
indicate unhashed dentries and use this in conjunction with a
per-dentry lock (d_lock). Once looked up without the dcache_lock,
we acquire the per-dentry lock (d_lock) and check if the dentry is
unhashed. If so, the look-up is failed. If not, the reference count
of the dentry is increased and the dentry is returned.
4. Once a dentry is looked up, it must be ensured during the path walk
for that component it doesn't go away. In pre-2.5.10 code, this was
done holding a reference to the dentry. dcache_rcu does the same.
In some sense, dcache_rcu path walking looks like the pre-2.5.10
version.
5. All dentry hash chain updates must take the dcache_lock as well as
the per-dentry lock in that order. dput() does this to ensure that
a dentry that has just been looked up in another CPU doesn't get
deleted before dget() can be done on it.
6. There are several ways to do reference counting of RCU protected
objects. One such example is in ipv4 route cache where deferred
freeing (using call_rcu()) is done as soon as the reference count
goes to zero. This cannot be done in the case of dentries because
tearing down of dentries require blocking (dentry_iput()) which
isn't supported from RCU callbacks. Instead, tearing down of
dentries happen synchronously in dput(), but actual freeing happens
later when RCU grace period is over. This allows safe lock-free
walking of the hash chains, but a matched dentry may have been
partially torn down. The checking of DCACHE_UNHASHED flag with
d_lock held detects such dentries and prevents them from being
returned from look-up.
Maintaining POSIX rename semantics
==================================
Since look-up of dentries is lock-free, it can race against a
concurrent rename operation. For example, during rename of file A to
B, look-up of either A or B must succeed. So, if look-up of B happens
after A has been removed from the hash chain but not added to the new
hash chain, it may fail. Also, a comparison while the name is being
written concurrently by a rename may result in false positive matches
violating rename semantics. Issues related to race with rename are
handled as described below :
1. Look-up can be done in two ways - d_lookup() which is safe from
simultaneous renames and __d_lookup() which is not. If
__d_lookup() fails, it must be followed up by a d_lookup() to
correctly determine whether a dentry is in the hash table or
not. d_lookup() protects look-ups using a sequence lock
(rename_lock).
2. The name associated with a dentry (d_name) may be changed if a
rename is allowed to happen simultaneously. To avoid memcmp() in
__d_lookup() go out of bounds due to a rename and false positive
comparison, the name comparison is done while holding the
per-dentry lock. This prevents concurrent renames during this
operation.
3. Hash table walking during look-up may move to a different bucket as
the current dentry is moved to a different bucket due to rename.
But we use hlists in dcache hash table and they are
null-terminated. So, even if a dentry moves to a different bucket,
hash chain walk will terminate. [with a list_head list, it may not
since termination is when the list_head in the original bucket is
reached]. Since we redo the d_parent check and compare name while
holding d_lock, lock-free look-up will not race against d_move().
4. There can be a theoretical race when a dentry keeps coming back to
original bucket due to double moves. Due to this look-up may
consider that it has never moved and can end up in a infinite loop.
But this is not any worse that theoretical livelocks we already
have in the kernel.
Important guidelines for filesystem developers related to dcache_rcu
====================================================================
1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
don't change. Only dcache internal implementation changes. However
filesystems *must not* delete from the dentry hash chains directly
using the list macros like allowed earlier. They must use dcache
APIs like d_drop() or __d_drop() depending on the situation.
2. d_flags is now protected by a per-dentry lock (d_lock). All access
to d_flags must be protected by it.
3. For a hashed dentry, checking of d_count needs to be protected by
d_lock.

Path walking and name lookup locking
====================================
Path resolution is the finding a dentry corresponding to a path name string, by
performing a path walk. Typically, for every open(), stat() etc., the path name
will be resolved. Paths are resolved by walking the namespace tree, starting
with the first component of the pathname (eg. root or cwd) with a known dentry,
then finding the child of that dentry, which is named the next component in the
path string. Then repeating the lookup from the child dentry and finding its
child with the next element, and so on.
Since it is a frequent operation for workloads like multiuser environments and
web servers, it is important to optimize this code.
Path walking synchronisation history:
Prior to 2.5.10, dcache_lock was acquired in d_lookup (dcache hash lookup) and
thus in every component during path look-up. Since 2.5.10 onwards, fast-walk
algorithm changed this by holding the dcache_lock at the beginning and walking
as many cached path component dentries as possible. This significantly
decreases the number of acquisition of dcache_lock. However it also increases
the lock hold time significantly and affects performance in large SMP machines.
Since 2.5.62 kernel, dcache has been using a new locking model that uses RCU to
make dcache look-up lock-free.
All the above algorithms required taking a lock and reference count on the
dentry that was looked up, so that may be used as the basis for walking the
next path element. This is inefficient and unscalable. It is inefficient
because of the locks and atomic operations required for every dentry element
slows things down. It is not scalable because many parallel applications that
are path-walk intensive tend to do path lookups starting from a common dentry
(usually, the root "/" or current working directory). So contention on these
common path elements causes lock and cacheline queueing.
Since 2.6.38, RCU is used to make a significant part of the entire path walk
(including dcache look-up) completely "store-free" (so, no locks, atomics, or
even stores into cachelines of common dentries). This is known as "rcu-walk"
path walking.
Path walking overview
=====================
A name string specifies a start (root directory, cwd, fd-relative) and a
sequence of elements (directory entry names), which together refer to a path in
the namespace. A path is represented as a (dentry, vfsmount) tuple. The name
elements are sub-strings, seperated by '/'.
Name lookups will want to find a particular path that a name string refers to
(usually the final element, or parent of final element). This is done by taking
the path given by the name's starting point (which we know in advance -- eg.
current->fs->cwd or current->fs->root) as the first parent of the lookup. Then
iteratively for each subsequent name element, look up the child of the current
parent with the given name and if it is not the desired entry, make it the
parent for the next lookup.
A parent, of course, must be a directory, and we must have appropriate
permissions on the parent inode to be able to walk into it.
Turning the child into a parent for the next lookup requires more checks and
procedures. Symlinks essentially substitute the symlink name for the target
name in the name string, and require some recursive path walking. Mount points
must be followed into (thus changing the vfsmount that subsequent path elements
refer to), switching from the mount point path to the root of the particular
mounted vfsmount. These behaviours are variously modified depending on the
exact path walking flags.
Path walking then must, broadly, do several particular things:
- find the start point of the walk;
- perform permissions and validity checks on inodes;
- perform dcache hash name lookups on (parent, name element) tuples;
- traverse mount points;
- traverse symlinks;
- lookup and create missing parts of the path on demand.
Safe store-free look-up of dcache hash table
============================================
Dcache name lookup
------------------
In order to lookup a dcache (parent, name) tuple, we take a hash on the tuple
and use that to select a bucket in the dcache-hash table. The list of entries
in that bucket is then walked, and we do a full comparison of each entry
against our (parent, name) tuple.
The hash lists are RCU protected, so list walking is not serialised with
concurrent updates (insertion, deletion from the hash). This is a standard RCU
list application with the exception of renames, which will be covered below.
Parent and name members of a dentry, as well as its membership in the dcache
hash, and its inode are protected by the per-dentry d_lock spinlock. A
reference is taken on the dentry (while the fields are verified under d_lock),
and this stabilises its d_inode pointer and actual inode. This gives a stable
point to perform the next step of our path walk against.
These members are also protected by d_seq seqlock, although this offers
read-only protection and no durability of results, so care must be taken when
using d_seq for synchronisation (see seqcount based lookups, below).
Renames
-------
Back to the rename case. In usual RCU protected lists, the only operations that
will happen to an object is insertion, and then eventually removal from the
list. The object will not be reused until an RCU grace period is complete.
This ensures the RCU list traversal primitives can run over the object without
problems (see RCU documentation for how this works).
However when a dentry is renamed, its hash value can change, requiring it to be
moved to a new hash list. Allocating and inserting a new alias would be
expensive and also problematic for directory dentries. Latency would be far to
high to wait for a grace period after removing the dentry and before inserting
it in the new hash bucket. So what is done is to insert the dentry into the
new list immediately.
However, when the dentry's list pointers are updated to point to objects in the
new list before waiting for a grace period, this can result in a concurrent RCU
lookup of the old list veering off into the new (incorrect) list and missing
the remaining dentries on the list.
There is no fundamental problem with walking down the wrong list, because the
dentry comparisons will never match. However it is fatal to miss a matching
dentry. So a seqlock is used to detect when a rename has occurred, and so the
lookup can be retried.
1 2 3
+---+ +---+ +---+
hlist-->| N-+->| N-+->| N-+->
head <--+-P |<-+-P |<-+-P |
+---+ +---+ +---+
Rename of dentry 2 may require it deleted from the above list, and inserted
into a new list. Deleting 2 gives the following list.
1 3
+---+ +---+ (don't worry, the longer pointers do not
hlist-->| N-+-------->| N-+-> impose a measurable performance overhead
head <--+-P |<--------+-P | on modern CPUs)
+---+ +---+
^ 2 ^
| +---+ |
| | N-+----+
+----+-P |
+---+
This is a standard RCU-list deletion, which leaves the deleted object's
pointers intact, so a concurrent list walker that is currently looking at
object 2 will correctly continue to object 3 when it is time to traverse the
next object.
However, when inserting object 2 onto a new list, we end up with this:
1 3
+---+ +---+
hlist-->| N-+-------->| N-+->
head <--+-P |<--------+-P |
+---+ +---+
2
+---+
| N-+---->
<----+-P |
+---+
Because we didn't wait for a grace period, there may be a concurrent lookup
still at 2. Now when it follows 2's 'next' pointer, it will walk off into
another list without ever having checked object 3.
A related, but distinctly different, issue is that of rename atomicity versus
lookup operations. If a file is renamed from 'A' to 'B', a lookup must only
find either 'A' or 'B'. So if a lookup of 'A' returns NULL, a subsequent lookup
of 'B' must succeed (note the reverse is not true).
Between deleting the dentry from the old hash list, and inserting it on the new
hash list, a lookup may find neither 'A' nor 'B' matching the dentry. The same
rename seqlock is also used to cover this race in much the same way, by
retrying a negative lookup result if a rename was in progress.
Seqcount based lookups
----------------------
In refcount based dcache lookups, d_lock is used to serialise access to
the dentry, stabilising it while comparing its name and parent and then
taking a reference count (the reference count then gives a stable place to
start the next part of the path walk from).
As explained above, we would like to do path walking without taking locks or
reference counts on intermediate dentries along the path. To do this, a per
dentry seqlock (d_seq) is used to take a "coherent snapshot" of what the dentry
looks like (its name, parent, and inode). That snapshot is then used to start
the next part of the path walk. When loading the coherent snapshot under d_seq,
care must be taken to load the members up-front, and use those pointers rather
than reloading from the dentry later on (otherwise we'd have interesting things
like d_inode going NULL underneath us, if the name was unlinked).
Also important is to avoid performing any destructive operations (pretty much:
no non-atomic stores to shared data), and to recheck the seqcount when we are
"done" with the operation. Retry or abort if the seqcount does not match.
Avoiding destructive or changing operations means we can easily unwind from
failure.
What this means is that a caller, provided they are holding RCU lock to
protect the dentry object from disappearing, can perform a seqcount based
lookup which does not increment the refcount on the dentry or write to
it in any way. This returned dentry can be used for subsequent operations,
provided that d_seq is rechecked after that operation is complete.
Inodes are also rcu freed, so the seqcount lookup dentry's inode may also be
queried for permissions.
With this two parts of the puzzle, we can do path lookups without taking
locks or refcounts on dentry elements.
RCU-walk path walking design
============================
Path walking code now has two distinct modes, ref-walk and rcu-walk. ref-walk
is the traditional[*] way of performing dcache lookups using d_lock to
serialise concurrent modifications to the dentry and take a reference count on
it. ref-walk is simple and obvious, and may sleep, take locks, etc while path
walking is operating on each dentry. rcu-walk uses seqcount based dentry
lookups, and can perform lookup of intermediate elements without any stores to
shared data in the dentry or inode. rcu-walk can not be applied to all cases,
eg. if the filesystem must sleep or perform non trivial operations, rcu-walk
must be switched to ref-walk mode.
[*] RCU is still used for the dentry hash lookup in ref-walk, but not the full
path walk.
Where ref-walk uses a stable, refcounted ``parent'' to walk the remaining
path string, rcu-walk uses a d_seq protected snapshot. When looking up a
child of this parent snapshot, we open d_seq critical section on the child
before closing d_seq critical section on the parent. This gives an interlocking
ladder of snapshots to walk down.
proc 101
/----------------\
/ comm: "vi" \
/ fs.root: dentry0 \
\ fs.cwd: dentry2 /
\ /
\----------------/
So when vi wants to open("/home/npiggin/test.c", O_RDWR), then it will
start from current->fs->root, which is a pinned dentry. Alternatively,
"./test.c" would start from cwd; both names refer to the same path in
the context of proc101.
dentry 0
+---------------------+ rcu-walk begins here, we note d_seq, check the
| name: "/" | inode's permission, and then look up the next
| inode: 10 | path element which is "home"...
| children:"home", ...|
+---------------------+
|
dentry 1 V
+---------------------+ ... which brings us here. We find dentry1 via
| name: "home" | hash lookup, then note d_seq and compare name
| inode: 678 | string and parent pointer. When we have a match,
| children:"npiggin" | we now recheck the d_seq of dentry0. Then we
+---------------------+ check inode and look up the next element.
|
dentry2 V
+---------------------+ Note: if dentry0 is now modified, lookup is
| name: "npiggin" | not necessarily invalid, so we need only keep a
| inode: 543 | parent for d_seq verification, and grandparents
| children:"a.c", ... | can be forgotten.
+---------------------+
|
dentry3 V
+---------------------+ At this point we have our destination dentry.
| name: "a.c" | We now take its d_lock, verify d_seq of this
| inode: 14221 | dentry. If that checks out, we can increment
| children:NULL | its refcount because we're holding d_lock.
+---------------------+
Taking a refcount on a dentry from rcu-walk mode, by taking its d_lock,
re-checking its d_seq, and then incrementing its refcount is called
"dropping rcu" or dropping from rcu-walk into ref-walk mode.
It is, in some sense, a bit of a house of cards. If the seqcount check of the
parent snapshot fails, the house comes down, because we had closed the d_seq
section on the grandparent, so we have nothing left to stand on. In that case,
the path walk must be fully restarted (which we do in ref-walk mode, to avoid
live locks). It is costly to have a full restart, but fortunately they are
quite rare.
When we reach a point where sleeping is required, or a filesystem callout
requires ref-walk, then instead of restarting the walk, we attempt to drop rcu
at the last known good dentry we have. Avoiding a full restart in ref-walk in
these cases is fundamental for performance and scalability because blocking
operations such as creates and unlinks are not uncommon.
The detailed design for rcu-walk is like this:
* LOOKUP_RCU is set in nd->flags, which distinguishes rcu-walk from ref-walk.
* Take the RCU lock for the entire path walk, starting with the acquiring
of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are
not required for dentry persistence.
* synchronize_rcu is called when unregistering a filesystem, so we can
access d_ops and i_ops during rcu-walk.
* Similarly take the vfsmount lock for the entire path walk. So now mnt
refcounts are not required for persistence. Also we are free to perform mount
lookups, and to assume dentry mount points and mount roots are stable up and
down the path.
* Have a per-dentry seqlock to protect the dentry name, parent, and inode,
so we can load this tuple atomically, and also check whether any of its
members have changed.
* Dentry lookups (based on parent, candidate string tuple) recheck the parent
sequence after the child is found in case anything changed in the parent
during the path walk.
* inode is also RCU protected so we can load d_inode and use the inode for
limited things.
* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.
* i_op can be loaded.
* When the destination dentry is reached, drop rcu there (ie. take d_lock,
verify d_seq, increment refcount).
* If seqlock verification fails anywhere along the path, do a full restart
of the path lookup in ref-walk mode. -ECHILD tends to be used (for want of
a better errno) to signal an rcu-walk failure.
The cases where rcu-walk cannot continue are:
* NULL dentry (ie. any uncached path element)
* Following links
It may be possible eventually to make following links rcu-walk aware.
Uncached path elements will always require dropping to ref-walk mode, at the
very least because i_mutex needs to be grabbed, and objects allocated.
Final note:
"store-free" path walking is not strictly store free. We take vfsmount lock
and refcounts (both of which can be made per-cpu), and we also store to the
stack (which is essentially CPU-local), and we also have to take locks and
refcount on final dentry.
The point is that shared data, where practically possible, is not locked
or stored into. The result is massive improvements in performance and
scalability of path resolution.
Interesting statistics
======================
The following table gives rcu lookup statistics for a few simple workloads
(2s12c24t Westmere, debian non-graphical system). Ungraceful are attempts to
drop rcu that fail due to d_seq failure and requiring the entire path lookup
again. Other cases are successful rcu-drops that are required before the final
element, nodentry for missing dentry, revalidate for filesystem revalidate
routine requiring rcu drop, permission for permission check requiring drop,
and link for symlink traversal requiring drop.
rcu-lookups restart nodentry link revalidate permission
bootup 47121 0 4624 1010 10283 7852
dbench 25386793 0 6778659(26.7%) 55 549 1156
kbuild 2696672 10 64442(2.3%) 108764(4.0%) 1 1590
git diff 39605 0 28 2 0 106
vfstest 24185492 4945 708725(2.9%) 1076136(4.4%) 0 2651
What this shows is that failed rcu-walk lookups, ie. ones that are restarted
entirely with ref-walk, are quite rare. Even the "vfstest" case which
specifically has concurrent renames/mkdir/rmdir/ creat/unlink/etc to excercise
such races is not showing a huge amount of restarts.
Dropping from rcu-walk to ref-walk mean that we have encountered a dentry where
the reference count needs to be taken for some reason. This is either because
we have reached the target of the path walk, or because we have encountered a
condition that can't be resolved in rcu-walk mode. Ideally, we drop rcu-walk
only when we have reached the target dentry, so the other statistics show where
this does not happen.
Note that a graceful drop from rcu-walk mode due to something such as the
dentry not existing (which can be common) is not necessarily a failure of
rcu-walk scheme, because some elements of the path may have been walked in
rcu-walk mode. The further we get from common path elements (such as cwd or
root), the less contended the dentry is likely to be. The closer we are to
common path elements, the more likely they will exist in dentry cache.

dcache_lock is gone, replaced by fine grained locks. See fs/dcache.c
for details of what locks to replace dcache_lock with in order to protect
particular things. Most of the time, a filesystem only needs ->d_lock, which
protects *all* the dcache state of a given dentry.

Filesystems must RCU-free their inodes, if they can have been accessed
via rcu-walk path walk (basically, if the file can have had a path name in the
vfs namespace).
i_dentry and i_rcu share storage in a union, and the vfs expects
i_dentry to be reinitialized before it is freed, so an:
INIT_LIST_HEAD(&inode->i_dentry);
must be done in the RCU callback.
--
[recommended]
vfs now tries to do path walking in "rcu-walk mode", which avoids
atomic operations and scalability hazards on dentries and inodes (see
Documentation/filesystems/path-walk.txt). d_hash and d_compare changes (above)
are examples of the changes required to support this. For more complex
filesystem callbacks, the vfs drops out of rcu-walk mode before the fs call, so
no changes are required to the filesystem. However, this is costly and loses
the benefits of rcu-walk mode. We will begin to add filesystem callbacks that
are rcu-walk aware, shown below. Filesystems should take advantage of this
where possible.
--
[mandatory]
d_revalidate is a callback that is made on every path element (if
the filesystem provides it), which requires dropping out of rcu-walk mode. This
may now be called in rcu-walk mode (nd->flags & LOOKUP_RCU). -ECHILD should be
returned if the filesystem cannot handle rcu-walk. See
Documentation/filesystems/vfs.txt for more details.
permission and check_acl are inode permission checks that are called
on many or all directory inodes on the way down a path walk (to check for
exec permission). These must now be rcu-walk aware (flags & IPERM_RCU). See
Documentation/filesystems/vfs.txt for more details.
