15 years agodrm: Add dirty ioctl and property
Jakob Bornecrantz [Thu, 3 Dec 2009 23:25:47 +0000 (23:25 +0000)]
drm: Add dirty ioctl and property

This commit adds a ioctl and property to allow userspace
to notify the kernel that a framebuffer has changed. Instead
of snooping the command stream this allows finer grained
tracking of which areas have changed.

The primary user for this functionality is virtual hardware
like the vmware svga device, but also Xen hardware likes to
be notify. There is also real hardware like DisplayLink and
DisplayPort that might take advantage of this ioctl.

The oops was caused by a bug of error path in

nilfs_ioctl_clean_segments().

nilfs_ioctl_move_blocks checks duplication of blocks which will be

ipip: Fix handling of DF packets when pmtudisc is OFF

RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel.  Our implementation does exactly that.

For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set.  As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.

Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.

This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set.  This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur.  For
hosts behind the IPIP gateway it is readily visible with a simple
ping.

This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.

cifs: don't use CIFSGetSrvInodeNumber in is_path_accessible

Because it's lighter weight, CIFS tries to use CIFSGetSrvInodeNumber to
verify the accessibility of the root inode and then falls back to doing a
full QPathInfo if that fails with -EOPNOTSUPP. I have at least a report
of a server that returns NT_STATUS_INTERNAL_ERROR rather than something
that translates to EOPNOTSUPP.

Rather than trying to be clever with that call, just have
is_path_accessible do a normal QPathInfo. That call is widely
supported and it shouldn't increase the overhead significantly.

In this situation turn off querying for server inode numbers, generate a

Once we generate any inode number with iunique we can no longer use any

ASoC: OMAP: Don't try to set unsupported OMAP_DMA_DATA_BURST_16 on OMAP1

After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c,
omap_pcm_prepare() unconditionally calls:

        omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
        omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);

Current implementation of those two functions found in
arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at

ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta.

Revert "ide: try to use PIO Mode 0 during probe if possible"

This reverts commit 6029336426a2b43e4bc6f4a84be8789a047d139e.

Ok, we really do need to revert this, even with Bart's sis5513.c
fix in there.

The problem is that several driver's ->set_pio_mode() method
depends upon the drive->media type being set properly.  Most
of them use this to enable prefetching, which can only be done
for disk media.

But the commit being reverted here calls ->set_pio_mode() before
it's setup.  Actually it considers everything disk because that
is the default media type set by ide_port_init_devices_data().

The set of drivers that depend upon the media type in their
->set_pio_method() are:

drivers/ide/alim15x3.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/qd65xx.c
drivers/ide/sis5513.c
drivers/ide/slc90e66.c

And it is possible that we could fix this by guarding the prefetching
and other media dependent setting changes with a test on
IDE_PFLAG_PROBING in hwif->port_flags, that's simply too risky for
2.6.32-rcX and -stable.

netfilter: nf_nat: fix NAT issue in 2.6.30.4+

Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work
over NAT. The "cause" of the problem was a fix of unacknowledged data
detection with NAT (commit a3a9f79e361e864f0e9d75ebe2a0cb43d17c4272).
However, actually, that fix uncovered a long standing bug in TCP conntrack:
when NAT was enabled, we simply updated the max of the right edge of
the segments we have seen (td_end), by the offset NAT produced with
changing IP/port in the data. However, we did not update the other parameter
(td_maxend) which is affected by the NAT offset. Thus that could drift
away from the correct value and thus resulted breaking active FTP.

The patch below fixes the issue by *not* updating the conntrack parameters
from NAT, but instead taking into account the NAT offsets in conntrack in a
consistent way. (Updating from NAT would be more harder and expensive because
it'd need to re-calculate parameters we already calculated in conntrack.)

until a resync (or reshape or recovery ...) actually reached that
point.
So if a resync is interrupted (e.g. by device failure),
leave 'resync_max' unchanged.

This is particularly important for 'reshape' operations that do not

monitor the reshape taking rolling backups of the section being

ACPI: Move dereference after NULL test

If the NULL test on pr is needed, then the dereference should be after the
NULL test.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;

@@

* x->fld
  ... when != \(x = E\|&x\)

ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine."

Ensure that memory mappings created for operation regions
do not cross page boundaries.  Crossing a page boundary
while mapping regions can cause warnings if the pages have different attributes.

Such regions are probably BIOS bugs, and this is the workaround.

ACPI: add __cpuinit to acpi_processor_add()

Annote acpi_processor_add with cpuinit since it calls a cpuinit function
acpi_processor_power_init and fixes a section mismatch warning.

 We were warned by the following warning:

 LD      drivers/acpi/processor.o
WARNING: drivers/acpi/processor.o(.text+0x1829): Section mismatch in
reference from the function acpi_processor_add() to the function
.cpuinit.text:acpi_processor_power_init()
The function acpi_processor_add() references
the function __cpuinit acpi_processor_power_init().
This is often because acpi_processor_add lacks a __cpuinit
annotation or the annotation of acpi_processor_power_init is wrong.
