security: avoid calling a NULL function pointer in drivers/video/tvaudio.c
commit 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1 upstream
NULL function pointers are very bad security wise. This one got caught by
kerneloops.org quite a few times, so it's happening in the field....
Fix is simple, check the function pointer for NULL, like 6 other places
in the same function are already doing.

drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)
commit 4b40893918203ee1a1f6a114316c2a19c072e9bd upstream
Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.
It only affects the Intel G33 series and newer.

ACPI: Ignore _BQC object when registering backlight device
upstream commmit: c2c789057f075022658b38b498755c29c1ba8055
According to acpi spec , the objectes of _BCL and _BCM are required if
integrated LCD is present and supports brightness level and the _BQC is
the optional object. So the _BQC object will be ignored when the backlight
device is registered.
At the same time when there is no _BQC object, the current brightness will
be
set to the maximum.

hwmon: (it87) Prevent power-off on Shuttle SN68PT
based on commit 98dd22c3e086d76058083432d4d8fb85f04bab90 upstream
On the Shuttle SN68PT, FAN_CTL2 is apparently not connected to a fan,
but to something else. One user has reported instant system power-off
when changing the PWM2 duty cycle, so we disable it.
I use the board name string as the trigger in case the same board is
ever used in other systems.

Check mapped ranges on sysfs resource files
commit b5ff7df3df9efab511244d5a299fce706c71af48 upstream
Check mapped ranges on sysfs resource files
This is loosely based on a patch by Jesse Barnes to check the user-space
PCI mappings though the sysfs interfaces. Quoting Jesse's original
explanation:
It's fairly common for applications to map PCI resources through sysfs.
However, with the current implementation, it's possible for an application
to map far more than the range corresponding to the resourceN file it
opened. This patch plugs that hole by checking the range at mmap time,
similar to what is done on platforms like sparc64 in their lower level
PCI remapping routines.
It was initially put together to help debug the e1000e NVRAM corruption
problem, since we initially thought an X driver might be walking past the
end of one of its mappings and clobbering the NVRAM. It now looks like
that's not the case, but doing the check is still important for obvious
reasons.
and this version of the patch differs in that it uses a helper function
to clarify the code, and does all the checks in pages (instead of bytes)
in order to avoid overflows when doing "<< PAGE_SHIFT" etc.

Don't allow splice() to files opened with O_APPEND
commit efc968d450e013049a662d22727cf132618dcb2f upstream
This is debatable, but while we're debating it, let's disallow the
combination of splice and an O_APPEND destination.
It's not entirely clear what the semantics of O_APPEND should be, and
POSIX apparently expects pwrite() to ignore O_APPEND, for example. So
we could make up any semantics we want, including the old ones.
But Miklos convinced me that we should at least give it some thought,
and that accepting writes at arbitrary offsets is wrong at least for
IS_APPEND() files (which always have O_APPEND set, even if the reverse
isn't true: you can obviously have O_APPEND set on a regular file).
So disallow O_APPEND entirely for now. I doubt anybody cares, and this
way we have one less gray area to worry about.

V4L: bttv: Prevent NULL pointer dereference in radio_open
(cherry picked from commit c37396c19403e249f12626187d51e92c915f2bc9)
Fix the following crash in the bttv driver:
BUG: unable to handle kernel NULL pointer dereference at 000000000000036c
IP: [<ffffffffa037860a>] radio_open+0x3a/0x170 [bttv]
This happens because radio_open assumes that all present bttv devices
have a radio function. If a bttv device without radio and one with
radio are installed on the same system, and the one without radio is
registered first, then radio_open checks for the radio device number
of a bttv device that has no radio function, and this breaks. All we
have to do to fix it is to skip bttv devices without a radio function.

libata: LBA28/LBA48 off-by-one bug in ata.h
commit 97b697a11b07e2ebfa69c488132596cc5eb24119 upstream
I recently bought 3 HGST P7K500-series 500GB SATA drives and
had trouble accessing the block right on the LBA28-LBA48 border.
Here's how it fails (same for all 3 drives):
# dd if=/dev/sdc bs=512 count=1 skip=268435455 > /dev/null
dd: reading `/dev/sdc': Input/output error

ata1.00: status: { DRDY ERR }
ata1.00: error: { ABRT }
ata1.00: configured for UDMA/33
ata1: EH complete
...
After some investigations, it turned out this seems to be caused
by misinterpretation of the ATA specification on LBA28 access.
Following part is the code in question:
=== include/linux/ata.h ===
static inline int lba_28_ok(u64 block, u32 n_block)
{
/* check the ending block number */
return ((block + n_block - 1) < ((u64)1 << 28)) && (n_block <= 256);
}
HGST drive (sometimes) fails with LBA28 access of {block = 0xfffffff,
n_block = 1}, and this behavior seems to be comformant. Other drives,
including other HGST drives are not that strict, through.
>From the ATA specification:
(http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf)
8.15.29 Word (61:60): Total number of user addressable sectors
This field contains a value that is one greater than the total number
of user addressable sectors (see 6.2). The maximum value that shall
be placed in this field is 0FFFFFFFh.
So the driver shouldn't use the value of 0xfffffff for LBA28 request
as this exceeds maximum user addressable sector. The logical maximum
value for LBA28 is 0xffffffe.
The obvious fix is to cut "- 1" part, and the patch attached just do
that. I've been using the patched kernel for about a month now, and
the same fix is also floating on the net for some time. So I believe
this fix works reliably.
Just FYI, many Windows/Intel platform users also seems to be struck
by this, and HGST has issued a note pointing to Intel ICH8/9 driver.
"28-bit LBA command is being used to access LBAs 29-bits in length"

Also, *BSDs seems to have similar fix included sometime around ~2004,
through I have not checked out exact portion of the code.

libata: always do follow-up SRST if hardreset returned -EAGAIN
commit 5dbfc9cb59d4ad75199949d7dd8a8c6d7bc518df upstream
As an optimization, follow-up SRST used to be skipped if
classification wasn't requested even when hardreset requested it via
-EAGAIN. However, some hardresets can't wait for device readiness and
skipping SRST can cause timeout or other failures during revalidation.
Always perform follow-up SRST if hardreset returns -EAGAIN. This
makes reset paths more predictable and thus less error-prone.
While at it, move hardreset error checking such that it's done right
after hardreset is finished. This simplifies followup SRST condition
check a bit and makes the reset path easier to modify.

CIFS: make sure we have the right resume info before calling CIFSFindNext
commit 0752f1522a9120f731232919f7ad904e9e22b8ce upstream
When we do a seekdir() or equivalent, we usually end up doing a
FindFirst call and then call FindNext until we get to the offset that we
want. The problem is that when we call FindNext, the code usually
doesn't have the proper info (mostly, the filename of the entry from the
last search) to resume the search.
Add a "last_entry" field to the cifs_search_info that points to the last
entry in the search. We calculate this pointer by using the
LastNameOffset field from the search parms that are returned. We then
use that info to do a cifs_save_resume_key before we call CIFSFindNext.
This patch allows CIFS to reliably pass the "telldir" connectathon test.

sched_rt.c: resch needed in rt_rq_enqueue() for the root rt_rq
commit f6121f4f8708195e88cbdf8dd8d171b226b3f858 upstream
While working on the new version of the code for SCHED_SPORADIC I
noticed something strange in the present throttling mechanism. More
specifically in the throttling timer handler in sched_rt.c
(do_sched_rt_period_timer()) and in rt_rq_enqueue().
The problem is that, when unthrottling a runqueue, rt_rq_enqueue() only
asks for rescheduling if the runqueue has a sched_entity associated to
it (i.e., rt_rq->rt_se != NULL).
Now, if the runqueue is the root rq (which has a rt_se = NULL)
rescheduling does not take place, and it is delayed to some undefined
instant in the future.
This imply some random bandwidth usage by the RT tasks under throttling.
For instance, setting rt_runtime_us/rt_period_us = 950ms/1000ms an RT
task will get less than 95%. In our tests we got something varying
between 70% to 95%.
Using smaller time values, e.g., 95ms/100ms, things are even worse, and
I can see values also going down to 20-25%!!
The tests we performed are simply running 'yes' as a SCHED_FIFO task,
and checking the CPU usage with top, but we can investigate thoroughly
if you think it is needed.
Things go much better, for us, with the attached patch... Don't know if
it is the best approach, but it solved the issue for us.

x86, early_ioremap: fix fencepost error
commit c613ec1a7ff3714da11c7c48a13bab03beb5c376 upstream
The x86 implementation of early_ioremap has an off by one error. If we get
an object which ends on the first byte of a page we undermap by one page and
this causes a crash on boot with the ASUS P5QL whose DMI table happens to
fit
this alignment.
The size computation is currently
last_addr = phys_addr + size - 1;
npages = (PAGE_ALIGN(last_addr) - phys_addr)
(Consider a request for 1 byte at alignment 0...)

Disabled CPUs are not in the cpu_present_map, so we can use

x86: Reserve FIRST_DEVICE_VECTOR in used_vectors bitmap.
Not in upstream above 2.6.27 due to change in the way this code works
(has been fixed differently there.)
Someone from the community found out, that after repeatedly unloading
and loading a device driver that uses MSI IRQs, the system eventually
assigned the vector initially reserved for IRQ0 to the device driver.
The reason for this is, that although IRQ0 is tied to the
FIRST_DEVICE_VECTOR when declaring the irq_vector table, the
corresponding bit in the used_vectors map is not set. So, if vectors are
released and assigned often enough, the vector will get assigned to
another interrupt. This happens more often with MSI interrupts as those
are exclusively using a vector.
Fix this by setting the bit for the FIRST_DEVICE_VECTOR in the bitmap.
