2010-04-29kgdb: don't needlessly skip PAGE_USER test for Fsl bookeWufei1-5/+0
The bypassing of this test is a leftover from 2.4 vintage kernels, and is no longer appropriate, or even used by KGDB. Currently KGDB uses probe_kernel_write() for all access to memory via the KGDB core, so it can simply be deleted. This fixes CVE-2010-1446.

2010-04-29spi: spidev_test gives error upon 1-byte transferHector Palacios1-1/+1
The sample application spidev_test.c is using SPI_IOC_MESSAGE ioctl to do an SPI transfer. This ioctl returns the number of bytes successfully transmitted or a negative error code upon erroneous completion. The application however is returning an error if the result of the ioclt if the return value is 1. This makes the application to fail upon 1-byte length transfers.

2010-04-29xfs: add a shrinker to background inode reclaimDave Chinner6-9/+120
On low memory boxes or those with highmem, kernel can OOM before the background reclaims inodes via xfssyncd. Add a shrinker to run inode reclaim so that it inode reclaim is expedited when memory is low. This is more complex than it needs to be because the VM folk don't want a context added to the shrinker infrastructure. Hence we need to add a global list of XFS mount structures so the shrinker can traverse them. Signed-off-by: Dave Chinner <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>

2010-04-28nfs d_revalidate() is too trigger-happy with d_drop()Al Viro1-0/+2
If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that. Bug had been there since at least 2006 (commit c636eb already has it), so it's definitely -stable fodder.

2010-04-28x86/PCI: compute Address Space length rather than using _LENBjorn Helgaas1-38/+2
ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <[email protected]> Signed-off-by: Jesse Barnes <[email protected]>

2010-04-28drivers/gpu/drm/drm_sysfs.c: sysfs files error handlingDan Carpenter1-9/+12
In the original code we used "j" as an iterator but we used "i" as an index. - for (j = 0; j < i; j++) - device_remove_file(&connector->kdev, - &connector_attrs[i]); Smatch complained about that because "i" was potentially passed the end of the array. Which makes sense if we should be using "j" there. I also thought that we should remove the files for &connector_attrs_opt1 but to do that I had to add separate iterators for &connector_attrs and &connector_attrs_opt1.

2010-04-28drm/radeon/kms/agp The wrong AGP chipset can cause a NULL pointer dereferenceRobert Fitzsimons1-6/+4
Selecting the wrong or no CONFIG_AGP_* chipset can cause a NULL pointer dereference when combined with CONFIG_DRM_RADEON_KMS and an old system with a R100 AGP card (should effect other cards too). The agp field will be set to NULL if no suitable AGP chipset driver is loaded, drm_agp_acquire already preforms a suitable NULL check so it can be used directly.
