2017-07-04f2fs: measure inode.i_blocks as generic filesystemChao Yu4-14/+17
Both in memory or on disk, generic filesystems record i_blocks with 512bytes sized sector count, also VFS sub module such as disk quota follows this rule, but f2fs records it with 4096bytes sized block count, this difference leads to that once we use dquota's function which inc/dec iblocks, it will make i_blocks of f2fs being inconsistent between in memory and on disk. In order to resolve this issue, this patch changes to make in-memory i_blocks of f2fs recording sector count instead of block count, meanwhile leaving on-disk i_blocks recording block count.

2017-07-04f2fs: require key for truncate(2) of encrypted fileEric Biggers1-3/+7
Currently, filesystems allow truncate(2) on an encrypted file without the encryption key. However, it's impossible to correctly handle the case where the size being truncated to is not a multiple of the filesystem block size, because that would require decrypting the final block, zeroing the part beyond i_size, then encrypting the block. As other modifications to encrypted file contents are prohibited without the key, just prohibit truncate(2) as well, making it fail with ENOKEY.

2017-07-04f2fs: dax: fix races between page faults and truncating pagesQiuyang Sun4-9/+43
Currently in F2FS, page faults and operations that truncate the pagecahe or data blocks, are completely unsynchronized. This can result in page fault faulting in a page into a range that we are changing after truncating, and thus we can end up with a page mapped to disk blocks that will be shortly freed. Filesystem corruption will shortly follow. This patch fixes the problem by creating new rw semaphore i_mmap_sem in f2fs_inode_info and grab it for functions removing blocks from extent tree and for read over page faults. The mechanism is similar to that in ext4. Signed-off-by: Qiuyang Sun <[email protected]> Reviewed-by: Chao Yu <[email protected]> Signed-off-by: Jaegeuk Kim <[email protected]>
