2014-04-03nilfs2: verify metadata sizes read from diskRyusuke Konishi5-0/+54
Add code to check sizes of on-disk data of metadata files such as inode size, segment usage size, DAT entry size, and checkpoint size. Although these sizes are read from disk, the current implementation doesn't check them. If these sizes are not sane on disk, it can cause out-of-range access to metadata or memory access overrun on metadata block buffers due to overflow in sundry calculations. Both lower limit and upper limit of metadata sizes are verified to prevent these issues.

2014-04-03nilfs2: implementation of NILFS_IOCTL_SET_SUINFO ioctlAndreas Rohner3-0/+101
With this ioctl the segment usage entries in the SUFILE can be updated from userspace. This is useful, because it allows the userspace GC to modify and update segment usage entries for specific segments, which enables it to avoid unnecessary write operations. If a segment needs to be cleaned, but there is no or very little reclaimable space in it, the cleaning operation basically degrades to a useless moving operation. In the end the only thing that changes is the location of the data and a timestamp in the segment usage information. With this ioctl the GC can skip the cleaning and update the segment usage entries directly instead. This is basically a shortcut to cleaning the segment. It is still necessary to read the segment summary information, but the writing of the live blocks can be skipped if it's not worth it.

2014-04-03drivers/rtc/rtc-da9055.c: remove use of regmap_irq_get_virq()Adam Thomson1-1/+3
Using platform_get_irq_byname() to retrieve the IRQ number returns the VIRQ number rather than the local IRQ number for the device. Passing that value then into regmap_irq_get_virq() causes a failure because the function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc).
