[RADEON]: Fix blanking return value.
If you'll recall, over a year ago, I pointed out that the current
Radeon driver erroneously returns -EINVAL for valid blanking codes,
here is a link to that thread:
http://lkml.org/lkml/2006/1/28/6
No other driver does this, and it confuses the X server into thinking
that the device does not support blanking properly.
I looked again and there is simply no reason for the Radeon driver to
return -EINVAL for FB_BLANK_NORMAL. It claims it wants to do this in
order to convince fbcon to blank in software, right here:
if (fb_blank(info, blank))
fbcon_generic_blank(vc, info, blank);
to software blank the screen. But it only causes that to happen
in the FB_BLANK_NORMAL case.
That makes no sense because the Radeon code does this:
val |= CRTC_DISPLAY_DIS;
in the FB_BLANK_NORMAL case so should be blanking the hardware, and
there is therefore no reason to SW blank by returning -EINVAL.

[PATCH] tty_io: fix race in master pty close/slave pty close path
This patch fixes a possible race that leads to double freeing an idr index.
When the master begin to close, release_dev() is called and then
pty_close() is called:
if (tty->driver->close)
tty->driver->close(tty, filp);
This is done without helding any locks other than BKL. Inside pty_close(),
being a master close, the devpts entry will be removed:
#ifdef CONFIG_UNIX98_PTYS
if (tty->driver == ptm_driver)
devpts_pty_kill(tty->index);
#endif
But devpts_pty_kill() will call get_node() that may sleep while waiting for
&devpts_root->d_inode->i_sem. When this happens and the slave is being
opened, tty_open() just found the driver and index:
driver = get_tty_driver(device, &index);
if (!driver) {
mutex_unlock(&tty_mutex);
return -ENODEV;
}
This part of the code is already protected under tty_mute. The problem is
that the slave close already got an index. Then init_dev() is called and
blocks waiting for the same &devpts_root->d_inode->i_sem.
When the master close resumes, it removes the devpts entry, and the
relation between idr index and the tty is gone. The master then sleeps
waiting for the tty_mutex on release_dev().
Slave open resumes and found no tty for that index. As result, a NULL tty
is returned and init_dev() doesn't flow to fast_track:
/* check whether we're reopening an existing tty */
if (driver->flags & TTY_DRIVER_DEVPTS_MEM) {
tty = devpts_get_tty(idx);
if (tty && driver->subtype == PTY_TYPE_MASTER)
tty = tty->link;
} else {
tty = driver->ttys[idx];
}
if (tty) goto fast_track;
The result of this, is that a new tty will be created and init_dev() returns
sucessfull. After returning, tty_mutex is dropped and master close may resume.
Master close finds it's the only use and both sides are closing, then releases
the tty and the index. At this point, the idr index is free, but slave still
has it.
Slave open then calls pty_open() and finds that tty->link->count is 0,
because there's no master and returns error. Then tty_open() calls
release_dev() which executes without any warning, as it was a case of last
slave close when the master is already closed (master->count == 0,
slave->count == 1). The tty is then released with the already released idr
index.
This normally would only issue a warning on idr_remove() but in case of a
customer's critical application, it's never too simple:
thread1: opens master, gets index X
thread1: begin closing master
thread2: begin opening slave with index X
thread1: finishes closing master, index X released
thread3: opens master, gets index X, just released
thread2: fails opening slave, releases index X <----
thread4: opens master, gets index X, init_dev() then find an already in use
and healthy tty and fails
If no more indexes are released, ptmx_open() will keep failing, as the
first free index available is X, and it will make init_dev() fail because
you're trying to "reopen a master" which isn't valid.
The patch notices when this race happens and make init_dev() fail
imediately. The init_dev() function is called with tty_mutex held, so it's
safe to continue with tty till the end of function because release_dev()
won't make any further changes without grabbing the tty_mutex.
Without the patch, on some machines it's possible get easily idr warnings
like this one:
idr_remove called for id=15 which is not allocated.

[PATCH] ext[34]: EA block reference count racing fix
There are race issues around ext[34] xattr block release code.
ext[34]_xattr_release_block() checks the reference count of xattr block
(h_refcount) and frees that xattr block if it is the last one reference it.
Unlike ext2, the check of this counter is unprotected by any lock.
ext[34]_xattr_release_block() will free the mb_cache entry before freeing
that xattr block. There is a small window between the check for the re
h_refcount ==1 and the call to mb_cache_entry_free(). During this small
window another inode might find this xattr block from the mbcache and reuse
it, racing a refcount updates. The xattr block will later be freed by the
first inode without notice other inode is still use it. Later if that
block is reallocated as a datablock for other file, then more serious
problem might happen.
We need put a lock around places checking the refount as well to avoid
racing issue. Another place need this kind of protection is in
ext3_xattr_block_set(), where it will modify the xattr block content in-
the-fly if the refcount is 1 (means it's the only inode reference it).
This will also fix another issue: the xattr block may not get freed at all
if no lock is to protect the refcount check at the release time. It is
possible that the last two inodes could release the shared xattr block at
the same time. But both of them think they are not the last one so only
decreased the h_refcount without freeing xattr block at all.
We need to call lock_buffer() after ext3_journal_get_write_access() to
avoid deadlock (because the later will call lock_buffer()/unlock_buffer
() as well).

[PATCH] uml: host VDSO fix
This fixes a problem seen by a number of people running UML on newer host
kernels. init would hang with an infinite segfault loop.
It turns out that the host kernel was providing a AT_SYSINFO_EHDR of
0xffffe000, which faked UML into believing that the host VDSO page could be
reused. However, AT_SYSINFO pointed into the middle of the address space, and
was unmapped as a result. Because UML was providing AT_SYSINFO_EHDR and
AT_SYSINFO to its own processes, these would branch to nowhere when trying to
use the VDSO.
The fix is to also check the location of AT_SYSINFO when deciding whether to
use the host's VDSO.

To avoid restarting when it is not possible to do work, we call into the

to fail if there are too many failed devices.

There are two errors that can lead to recovery problems with raid10
when used in 'far' more (not the default).
Due to a '>' instead of '>=' the wrong block is located which would result in
garbage being written to some random location, quite possible outside the
range of the device, causing the newly reconstructed device to fail.
The device size calculation had some rounding errors (it didn't round when it
should) and so recovery would go a few blocks too far which would again cause
a write to a random block address and probably a device error.
The code for working with device sizes was fairly confused and spread out, so
this has been tided up a bit.

HID: fix Logitech DiNovo Edge touchwheel and Logic3 /SpectraVideo middle button
Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.
The commit
35068976916fdef82d6e69ef1f8c9a1c47732759 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.
To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we
disable remapping for key, abs and rel events only for this hardware.

HID: fix broken Logitech S510 keyboard report descriptor; make extra keys work
This patch makes extra keys (F1-F12 in special mode, zooming, rotate, shuffle)
on Logitech S510 keyboard work.
Logitech S510 keyboard sends in report no. 3 keys which are far above the
logical maximum described in descriptor for given report.
This patch introduces a HID quirk for this wireless USB receiver/keyboard
in order to fix the report descriptor before it's being parsed - the logical
maximum and the number of usages is bumped up to 0x104d). The values are in the
"Reserved" area of consumer HUT, so HID_MAX_USAGE had to be changed too.
In addition to proper extracting of the values from report descriptor, proper
HID-input mapping is introduced for them.

[PATCH] x86_64/i386 irq: Fix !CONFIG_SMP compilation
When removing set_native_irq I missed the fact that it was
called in a couple of places that were compiled even when
SMP support is disabled. And since the irq_desc[].affinity
field only exists in SMP things broke.
Thanks to Simon Arlott <simon@arlott.org> for spotting this.
There are a couple of ways to fix this but the simplest one
is to just remove the assignments. The affinity field is only
used to display a value to the user, and nothing on either i386
or x86_64 reads it or depends on it being any particlua value,
so skipping the assignment is safe. The assignment that
is being removed is just for the initial affinity value before
the user explicitly sets it. The irq_desc array initializes
this field to CPU_MASK_ALL so the field is initialized to
a reasonable value in the SMP case without being set.
