11 years agoprevent cifs_writepages() from skipping unwritten pages
Dave Kleikamp [Tue, 18 Nov 2008 03:49:05 +0000]
prevent cifs_writepages() from skipping unwritten pages

Fixes a data corruption under heavy stress in which pages could be left
dirty after all open instances of a inode have been closed.

In order to write contiguous pages whenever possible, cifs_writepages()
asks pagevec_lookup_tag() for more pages than it may write at one time.
Normally, it then resets index just past the last page written before calling
pagevec_lookup_tag() again.

If cifs_writepages() can't write the first page returned, it wasn't resetting
index, and the next call to pagevec_lookup_tag() resulted in skipping all of
the pages it previously returned, even though cifs_writepages() did nothing
with them.  This can result in data loss when the file descriptor is about
to be closed.

This patch ensures that index gets set back to the next returned page so
that none get skipped.

11 years agoFix inotify watch removal/umount races
Al Viro [Sat, 15 Nov 2008 01:15:43 +0000]
Fix inotify watch removal/umount races

Inotify watch removals suck violently.

To kick the watch out we need (in this order) inode->inotify_mutex and
ih->mutex.  That's fine if we have a hold on inode; however, for all
other cases we need to make damn sure we don't race with umount.  We can
*NOT* just grab a reference to a watch - inotify_unmount_inodes() will
happily sail past it and we'll end with reference to inode potentially
outliving its superblock.

Ideally we just want to grab an active reference to superblock if we
can; that will make sure we won't go into inotify_umount_inodes() until
we are done.  Cleanup is just deactivate_super().

However, that leaves a messy case - what if we *are* racing with
umount() and active references to superblock can't be acquired anymore?
We can bump ->s_count, grab ->s_umount, which will almost certainly wait
until the superblock is shut down and the watch in question is pining
for fjords.  That's fine, but there is a problem - we might have hit the
window between ->s_active getting to 0 / ->s_count - below S_BIAS (i.e.
the moment when superblock is past the point of no return and is heading
for shutdown) and the moment when deactivate_super() acquires
->s_umount.

We could just do drop_super() yield() and retry, but that's rather
antisocial and this stuff is luser-triggerable.  OTOH, having grabbed
->s_umount and having found that we'd got there first (i.e.  that
->s_root is non-NULL) we know that we won't race with
inotify_umount_inodes().

So we could grab a reference to watch and do the rest as above, just
with drop_super() instead of deactivate_super(), right? Wrong.  We had
to drop ih->mutex before we could grab ->s_umount.  So the watch
could've been gone already.

That still can be dealt with - we need to save watch->wd, do idr_find()
and compare its result with our pointer.  If they match, we either have
the damn thing still alive or we'd lost not one but two races at once,
the watch had been killed and a new one got created with the same ->wd
at the same address.  That couldn't have happened in inotify_destroy(),
but inotify_rm_wd() could run into that.  Still, "new one got created"
is not a problem - we have every right to kill it or leave it alone,
whatever's more convenient.

So we can use idr_find(...) == watch && watch->inode->i_sb == sb as
"grab it and kill it" check.  If it's been our original watch, we are
fine, if it's a newcomer - nevermind, just pretend that we'd won the
race and kill the fscker anyway; we are safe since we know that its
superblock won't be going away.

And yes, this is far beyond mere "not very pretty"; so's the entire
concept of inotify to start with.

Introduce a pr_fmt() macro that is applied for every pr_xyz macro to the

("PCI/iommu: blacklist DMAR on Intel G31/G33 chipsets"), where we do

moving to a per-server list. This entails adding a new list head to the
TCP_Server_Info struct. The refcounting for the cifsSesInfo is moved to
a non-atomic variable. We have to protect it by a lock anyway, so there's
no benefit to making it an atomic. The list and refcount are protected
by the global cifs_tcp_ses_lock.

libata: improve phantom device detection

Currently libata uses four methods to detect device presence.

1. PHY status if available.
2. TF register R/W test (only promotes presence, never demotes)
3. device signature after reset
4. IDENTIFY failure detection in SFF state machine

Combination of the above works well in most cases but recently there
have been a few reports where a phantom device causes unnecessary
delay during probe.  In both cases, PHY status wasn't available.  In
one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which
didn't qualify as #4.  The other failed #2 but as it passed #3 and #4,
it still caused failure.

In both cases, phantom device reported diagnostic failure, so these
cases can be safely worked around by considering any !ATA_DRQ IDENTIFY
failure as NODEV_HINT if diagnostic failure is set.

11 years agophylib: fix premature freeing of struct mii_bus
Lennert Buytenhek [Sun, 9 Nov 2008 04:34:47 +0000]
phylib: fix premature freeing of struct mii_bus

Commit 46abc02175b3c246dd5141d878f565a8725060c9 ("phylib: give mdio
buses a device tree presence") added a call to device_unregister() in
a situation where the caller did not intend for the device to be
freed yet, but apart from just unregistering the device from the
system, device_unregister() does an additional put_device() that is
intended to free it.

The right function to use in this situation is device_del(), which
unregisters the device from the system like device_unregister() does,
but without dropping the reference count an additional time.

scm: fix scm_fp_list->list initialization made in wrong place

This is the next page of the scm recursion story (the commit
f8d570a4 net: Fix recursive descent in __scm_destroy()).

In function scm_fp_dup(), the INIT_LIST_HEAD(&fpl->list) of newly
created fpl is done *before* the subsequent memcpy from the old
structure and thus the freshly initialized list is overwritten.

But that's OK, since this initialization is not required at all,
since the fpl->list is list_add-ed at the destruction time in any
case (and is unused in other code), so I propose to drop both
initializations, rather than moving it after the memcpy.

Please, correct me if I miss something significant.

With CONFIG_IRQSOFF_TRACER the trace_hardirqs_off() function includes

from early entry code. There we have just a single stack frame.
So this results in a kernel stack backchain walk that would walk beyond
the kernel stack. Following the NULL terminated backchain this results
in a lowcore read access.

V4L/DVB (9624): CVE-2008-5033: fix OOPS on tvaudio when controlling bass/treble

This bug were supposed to be fixed by 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1,
where a call to NULL happens.

Not all tvaudio chips allow controlling bass/treble. So, the driver
has a table with a flag to indicate if the chip does support it.

Unfortunately, the handling of this logic were broken for a very long
time (probably since the first module version). Due to that, an OOPS
were generated for devices that don't support bass/treble.

This were the resulting OOPS message before the patch, with debug messages
enabled:

There were no check about the limits of shadow.bytes array. This offers
a risk of writing values outside the limits, overriding other data
areas.

Instead of storing the pointer for the proper entry at chip description
table, the driver were storing an indirect reference, by using an index.

V4L/DVB (9618): tvaudio: add additional logic to avoid OOPS

This patch checks for volume, bass, treble, set mode and get mode
callbacks before actually enabling the code that would use them.

Instead of aborting the driver for load, this patch will allow it to
load with a reduced number of functionatities.

This prevents OOPS if some board entry is missing a needed callback.

V4L/DVB (9617): tvtime: remove generic_checkmode callback

generic_checkmode() were called, via a callback, for some tvaudio chips.
There's just one callback code used on all those boards. So, it makes no
sense on keeping this as a callback.

Since there were some OOPS reported on tvaudio on kerneloops.org, this
patch removes this callback, adding the code at the only place were it
is called: inside chip_tread. A flag were added to indicate the need for
a kernel thread to set stereo mode on cards that needs it.

Using this more direct approach simplifies the code, making it more
robust against human errors.

[CIFS] clean up server protocol handling

We're currently declaring both a sockaddr_in and sockaddr6_in on the
stack, but we really only need storage for one of them. Declare a
sockaddr struct and cast it to the proper type. Also, eliminate the
protocolType field in the TCP_Server_Info struct. It's redundant since
we have a sa_family field in the sockaddr anyway.

We may need to revisit this if SCTP is ever implemented, but for now
this will simplify the code.

CIFS over IPv6 also has a number of problems currently. This fixes all
of them that I found. Eventually, it would be nice to move more of the
code to be protocol independent, but this is a start.

dm: avoid destroying table in dm_any_congested

dm_any_congested() just checks for the DMF_BLOCK_IO and has no
code to make sure that suspend waits for dm_any_congested() to
complete.  This patch adds such a check.

Without it, a race can occur with dm_table_put() attempting to
destroying the table in the wrong thread, the one running
dm_any_congested() which is meant to be quick and return
immediately.

Two examples of problems:
1. Sleeping functions called from congested code, the caller
   of which holds a spin lock.
2. An ABBA deadlock between pdflush and multipathd. The two locks
   in contention are inode lock and kernel lock.

This doesn't fix any bug, just moves wake_up immediately after decrementing
md->pending, for better code readability.

It must be clear to anyone manipulating md->pending to wake up
