pci: use security_capable() when checking capablities during config space read
This reintroduces commit
47970b1b which was subsequently reverted
as
f00eaeea. The original change was broken and caused X startup
failures and generally made privileged processes incapable of reading
device dependent config space. The normal capable() interface returns
true on success, but the LSM interface returns 0 on success. This thinko
is now fixed in this patch, and has been confirmed to work properly.
So, once again...Eric Paris noted that commit de139a3 ("pci: check caps
from sysfs file open to read device dependent config space") caused the
capability check to bypass security modules and potentially auditing.
Rectify this by calling security_capable() when checking the open file's
capabilities for config space reads.

btrfs: prevent heap corruption in btrfs_ioctl_space_info()
Commit
bf5fc093c5b625e4259203f1cee7ca73488a5620 refactored
btrfs_ioctl_space_info() and introduced several security issues.
space_args.space_slots is an unsigned 64-bit type controlled by a
possibly unprivileged caller. The comparison as a signed int type
allows providing values that are treated as negative and cause the
subsequent allocation size calculation to wrap, or be truncated to 0.
By providing a size that's truncated to 0, kmalloc() will return
ZERO_SIZE_PTR. It's also possible to provide a value smaller than the
slot count. The subsequent loop ignores the allocation size when
copying data in, resulting in a heap overflow or write to ZERO_SIZE_PTR.
The fix changes the slot count type and comparison typecast to u64,
which prevents truncation or signedness errors, and also ensures that we
don't copy more data than we've allocated in the subsequent loop. Note
that zero-size allocations are no longer possible since there is already
an explicit check for space_args.space_slots being 0 and truncation of
this value is no longer an issue.

Btrfs: don't release pages when we can't clear the uptodate bits
Btrfs tracks uptodate state in an rbtree as well as in the
page bits. This is supposed to enable us to use block sizes other than
the page size, but there are a few parts still missing before that
completely works.
But, our readpage routine trusts this additional range based tracking
of uptodateness, much in the same way the buffer head up to date bits
are trusted for the other filesystems.
The problem is that sometimes we need to allocate memory in order to
split records in the rbtree, even when we are just clearing bits. This
can be difficult when our clearing function is called GFP_ATOMIC, which
can happen in the releasepage path.
So, what happens today looks like this:
releasepage called with GFP_ATOMIC
btrfs_releasepage calls clear_extent_bit
clear_extent_bit fails to allocate ram, leaving the up to date bit set
btrfs_releasepage returns success
The end result is the page being gone, but btrfs thinking the range is
up to date. Later on if someone tries to read that same page, the
btrfs readpage code will return immediately thinking the page is already
up to date.
This commit fixes things to fail the releasepage when we can't clear the
extent state bits. It covers both data pages and metadata tree blocks.

dma: ipu_idmac: do not lose valid received data in the irq handler
Currently when two or more buffers are queued by the camera driver
and so the double buffering is enabled in the idmac, we lose one
frame comming from CSI since the reporting of arrival of the first
frame is deferred by the DMAIC_7_EOF interrupt handler and reporting
of the arrival of the last frame is not done at all. So when requesting
N frames from the image sensor we actually receive N - 1 frames in
user space.
The reason for this behaviour is that the DMAIC_7_EOF interrupt
handler misleadingly assumes that the CUR_BUF flag is pointing to the
buffer used by the IDMAC. Actually it is not the case since the
CUR_BUF flag will be flipped by the FSU when the FSU is sending the
<TASK>_NEW_FRM_RDY signal when new frame data is delivered by the CSI.
When sending this singal, FSU updates the DMA_CUR_BUF and the
DMA_BUFx_RDY flags: the DMA_CUR_BUF is flipped, the DMA_BUFx_RDY
is cleared, indicating that the frame data is beeing written by
the IDMAC to the pointed buffer. DMA_BUFx_RDY is supposed to be
set to the ready state again by the MCU, when it has handled the
received data. DMAIC_7_CUR_BUF flag won't be flipped here by the
IPU, so waiting for this event in the EOF interrupt handler is wrong.
Actually there is no spurious interrupt as described in the comments,
this is the valid DMAIC_7_EOF interrupt indicating reception of the
frame from CSI.
The patch removes code that waits for flipping of the DMAIC_7_CUR_BUF
flag in the DMAIC_7_EOF interrupt handler. As the comment in the
current code denotes, this waiting doesn't help anyway. As a result
of this removal the reporting of the first arrived frame is not
deferred to the time of arrival of the next frame and the drivers
software flag 'ichan->active_buffer' is in sync with DMAIC_7_CUR_BUF
flag, so the reception of all requested frames works.
This has been verified on the hardware which is triggering the
image sensor by the programmable state machine, allowing to
obtain exact number of frames. On this hardware we do not tolerate
losing frames.
This patch also removes resetting the DMA_BUFx_RDY flags of
all channels in ipu_disable_channel() since transfers on other
DMA channels might be triggered by other running tasks and the
buffers should always be ready for data sending or reception.

klist: Fix object alignment on 64-bit.
Commit
c0e69a5bbc6f ("klist.c: bit 0 in pointer can't be used as flag")
intended to make sure that all klist objects were at least pointer size
aligned, but used the constant "4" which only works on 32-bit.
Use "sizeof(void *)" which is correct in all cases.

drm/radeon/kms: check AA resolve registers on r300
This is an important security fix because we allowed arbitrary values
to be passed to AARESOLVE_OFFSET. This also puts the right buffer address
in the register.

drm/radeon/kms: use linear aligned for evergreen/ni bo blits
Not only is linear aligned supposedly more performant,
linear general is only supported by the CB in single
slice mode. The texture hardware doesn't support
linear general, but I think the hw automatically
upgrades it to linear aligned.

drm/radeon: fix race between GPU reset and TTM delayed delete thread.
My evergreen has been in a remote PC for week and reset has never once
saved me from certain doom, I finally relocated to the box with a
serial cable and noticed an oops when the GPU resets, and the TTM
delayed delete thread tries to remove something from the GTT.
This stops the delayed delete thread from executing across the GPU
reset handler, and woot I can GPU reset now.
