10 years agofreeze_bdev: grab active reference to frozen superblocks

freeze_bdev: grab active reference to frozen superblocks

Currently we held s_umount while a filesystem is frozen, despite that we
might return to userspace and unlock it from a different process.  Instead
grab an active reference to keep the file system busy and add an explicit
check for frozen filesystems in remount and reject the remount instead
of blocking on s_umount.

Add a new get_active_super helper to super.c for use by freeze_bdev that
grabs an active reference to a superblock from a given block device.

10 years agofreeze_bdev: kill bd_mount_sem

freeze_bdev: kill bd_mount_sem

Now that we have the freeze count there is not much reason for bd_mount_sem
anymore.  The actual freeze/thaw operations are serialized using the
bd_fsfreeze_mutex, and the only other place we take bd_mount_sem is
get_sb_bdev which tries to prevent mounting a filesystem while the block
device is frozen.  Instead of add a check for bd_fsfreeze_count and
return -EBUSY if a filesystem is frozen.  While that is a change in user
visible behaviour a failing mount is much better for this case rather
than having the mount process stuck uninterruptible for a long time.

10 years agoexofs: remove BKL from super operations
Boaz Harrosh [Wed, 19 Aug 2009 14:56:46 +0000]
exofs: remove BKL from super operations

the two places inside exofs that where taking the BKL were:
exofs_put_super() - .put_super
and
exofs_sync_fs() - which is .sync_fs and is also called from
                  .write_super.

Now exofs_sync_fs() is protected from itself by also taking
the sb_lock.

exofs_put_super() directly calls exofs_sync_fs() so there is no
danger between these two either.

In anyway there is absolutely nothing dangerous been done
inside exofs_sync_fs().

Unless there is some subtle race with the actual lifetime of
the super_block in regard to .put_super and some other parts
of the VFS. Which is highly unlikely.

10 years agovfs: change sb->s_maxbytes to a loff_t
Jeff Layton [Fri, 18 Sep 2009 20:05:53 +0000]
vfs: change sb->s_maxbytes to a loff_t

sb->s_maxbytes is supposed to indicate the maximum size of a file that can
exist on the filesystem.  It's declared as an unsigned long long.

Even if a filesystem has no inherent limit that prevents it from using
every bit in that unsigned long long, it's still problematic to set it to
anything larger than MAX_LFS_FILESIZE.  There are places in the kernel
that cast s_maxbytes to a signed value.  If it's set too large then this
cast makes it a negative number and generally breaks the comparison.

Change s_maxbytes to be loff_t instead.  That should help eliminate the
temptation to set it too large by making it a signed value.

Also, add a warning for couple of releases to help catch filesystems that
set s_maxbytes too large.  Eventually we can either convert this to a
BUG() or just remove it and in the hope that no one will get it wrong now
that it's a signed value.

vfs: optimization for touch_atime()

Some benchmark testing shows touch_atime to be high up in profile logs for
IO intensive workloads.  Most likely that's due to the lock in
mnt_want_write().  Unfortunately touch_atime first takes the lock, and
then does all the other tests that could avoid atime updates (like noatime
or relatime).

Do it the other way round -- first try to avoid the update and only then
if that didn't succeed take the lock.  That works because none of the
atime avoidance tests rely on locking.

This also eliminates a goto.

Revert "kmod: fix race in usermodehelper code"

This reverts commit c02e3f361c7 ("kmod: fix race in usermodehelper code")

The patch is wrong.  UMH_WAIT_EXEC is called with VFORK what ensures
that the child finishes prior returing back to the parent.  No race.

In fact, the patch makes it even worse because it does the thing it
claims not do:

 - It calls ->complete() on UMH_WAIT_EXEC

 - the complete() callback may de-allocated subinfo as seen in the
   following call chain:

    [<c009f904>] (__link_path_walk+0x20/0xeb4) from [<c00a094c>] (path_walk+0x48/0x94)

    [<c0026a80>] (kernel_execve+0x34/0x80) from [<c004b514>] (____call_usermodehelper+0x130/0x148)
    [<c004b514>] (____call_usermodehelper+0x130/0x148) from [<c0024858>] (kernel_thread_exit+0x0/0x8)

   and the path pointer was NULL.  Good that ARM's kernel_execve()
   doesn't check the pointer for NULL or else I wouldn't notice it.

The only race there might be is with UMH_NO_WAIT but it is too late for
me to investigate it now.  UMH_WAIT_PROC could probably also use VFORK
and we could save one exec.  So the only race I see is with UMH_NO_WAIT
and recent scheduler changes where the child does not always run first
might have trigger here something but as I said, it is late....

10 years agocpumask: remove unused mask field from struct irqaction.
Rusty Russell [Thu, 24 Sep 2009 15:34:37 +0000]
cpumask: remove unused mask field from struct irqaction.

Up until 1.1.83, the primitive human tribes used struct sigaction for
interrupts.  The sa_mask field was overloaded to hold a pointer to the
name.

When someone created the new "struct irqaction" they carried across
the "mask" field as a kind of ancestor worship: the fact that it was
unused makes clear its spiritual significance.

cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL.: mips

(Thanks to Al Viro for reminding me of this, via Ingo)

CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:

#define CPU_MASK_ALL (cpumask_t) { { ... } }

Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:

#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)

Which formalizes this practice.  One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).

So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real struct cpumask *), and remove
CPU_MASK_ALL_PTR altogether.

faults. The faults are not yet exposed via sysfs, however it may be useful
for userspace to read the fault register directly with the i2cget command.
Clear the fault register when the driver is installed so userspace doesn't
have to worry about spurious fault indications.

NFS: Propagate 'fsc' mount option through automounts

commit c02d7adf8c5429727a98bad1d039bccad4c61c50
Author: Trond Myklebust <Trond.Myklebust@netapp.com>

NFSv4: Replace nfs4_path_walk() with VFS path lookup in a private namespace

uses VFS-driven automounting to reach all submounts barring the root, thus
preventing fscaching from being enabled on any submount other than the root.

This patch gets around that by propagating the NFS_OPTION_FSCACHE flag across

10 years agoNFS/RPC: fix problems with reestablish_timeout and related code.
Neil Brown [Wed, 23 Sep 2009 18:36:37 +0000]
NFS/RPC: fix problems with reestablish_timeout and related code.

[[resending with correct cc:  - "vfs.kernel.org" just isn't right!]]

xprt->reestablish_timeout is used to cause TCP connection attempts to
back off if the connection fails so as not to hammer the network,
but to still allow immediate connections when there is no reason to
believe there is a problem.

It is not used for the first connection (when transport->sock is NULL)
but only on reconnects.

It is currently set:

 a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1
    on the assumption that the client has closed the connection
    so the reconnect should be immediate when needed.
 b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change
    detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the
    server closed the connection so a small delay at least is
    required.
 c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that
    it is never 0 while a connection has been attempted, else
    the doubling will produce 0 and there will be no backoff.
 d/ to double is value (up to a limit) when delaying a connection,
    thus providing exponential backoff and
 e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation.

So you can see it is highly dependant on xs_tcp_state_change being
called as expected.  However experimental evidence shows that
xs_tcp_state_change does not see all state changes.
("rpcdebug -m rpc trans" can help show what actually happens).

Results show:
 TCP_ESTABLISHED is reported when a connection is made.  TCP_SYN_SENT
 is never reported, so rule 'c' above is never effective.

 When the server closes the connection, TCP_CLOSE_WAIT and
 TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always
 reported.  This rule 'b' above will sometimes be effective, but
 not reliably.

 When the client closes the connection, it used to result in
 TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE.  However since commit
 f75e674 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on
 reconnect) we don't see *any* events on client-close.  I think this
 is because xs_restore_old_callbacks is called to disconnect
 xs_tcp_state_change before the socket is closed.
 In any case, rule 'a' no longer applies.

So all that is left are rule d, which successfully doubles the
timeout which is never rest, and rule e which initialises the timeout.

Even if the rules worked as expected, there would be a problem because
a successful connection does not reset the timeout, so a sequence
of events where the server closes the connection (e.g. during failover
testing) will cause longer and longer timeouts with no good reason.

This patch:

 - sets reestablish_timeout to 0 in xs_close thus effecting rule 'a'
 - sets it to 0 in xs_tcp_data_ready to ensure that a successful
   connection resets the timeout
 - sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,
   thus effecting rule c

I have not reimplemented rule b and the new version of rule c
seems sufficient.

I suspect other code in xs_tcp_data_ready needs to be revised as well.
For example I don't think connect_cookie is being incremented as often
as it should be.

KEYS: Have the garbage collector set its timer for live expired keys

The key garbage collector sets a timer to start a new collection cycle at the
point the earliest key to expire should be considered garbage.  However, it
currently only does this if the key it is considering hasn't yet expired.

If the key being considering has expired, but hasn't yet reached the collection
time then it is ignored, and won't be collected until some other key provokes a
round of collection.

Make the garbage collector set the timer for the earliest key that hasn't yet
passed its collection time, rather than the earliest key that hasn't yet
expired.

9p: Add fscache support to 9p

This patch adds a persistent, read-only caching facility for
9p clients using the FS-Cache caching backend.

When the fscache facility is enabled, each inode is associated
with a corresponding vcookie which is an index into the FS-Cache
indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
- session object associated with each mount.
- inode/vcookie
- actual data (pages)

A cache tag is chosen randomly for each session. These tags can
be read off /sys/fs/9p/caches and can be passed as a mount-time
parameter to re-attach to the specified caching session.

updated correctly on a remote write. Thus subsequent reads of
the whole file resulted in a truncated read. Fix it.

9p: Use the i_size_[read, write]() macros instead of using inode->i_size directly.

Change all occurrence of inode->i_size with i_size_read() or i_size_write()
as appropriate.
