| | | | | | | | | | | | | | | | | | | | | | | | | | | I add the check on the return value of alloc_extent_map() to several places. In addition, alloc_extent_map() returns only the address or NULL.

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 bitsChris Mason2011-02-141-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Chris Mason <chris.mason@oracle.com>
| * | Btrfs: fix page->private racesChris Mason2011-02-142-5/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race where btrfs_releasepage can drop the page->private contents just as alloc_extent_buffer is setting up pages for metadata. Because of how the Btrfs page flags work, this results in us skipping the crc on the page during IO. This patch sovles the race by waiting until after the extent buffer is inserted into the radix tree before it sets page private. Signed-off-by: Chris Mason <chris.mason@oracle.com>

Re-enable the use of V6K instructions on such kernels, and let such kernels running on V6 CPUs eat undefined instruction faults which will be much safer than filesystem corruption. Next merge window we can fix this properly (as it requires a much bigger set of changes.) Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

With the recent virtualization of the RTC layer, its now important that the generic layer always be used. This patch moved the rtc driver ioctl method call to after the generic ioctl processing is done. This allows hardware specific features or ioctls to still function, while relying on the generic code for handling everything else. This patch on its own may more obviously break rtc drivers that implement the alarm irq enablement via their ioctl method instead of implementing the alarm_irq_eanble method. Those drivers will be fixed in a following patch. Additionaly, those drivers are already likely to not be functioning reliably without this patch.

This is different from the DA850/OMAP-L138 platform which uses McASP0. This is fixed by adding a new snd_soc_dai_link struct.

This has changed, probably unintentionally, after recent refactorings. Since the function implementations are free to make use of this pointer, move its assignment back before the function is called to avoid NULL pointer dereferences.
