2016-09-15f2fs: exclude special cases for f2fs_move_file_rangeFan Li1-0/+7
When src and dst is the same file, and the latter part of source region overlaps with the former part of destination region, current implement will overwrite data which hasn't been moved yet and truncate data in overlapped region. This patch return -EINVAL when such cases occur and return 0 when source region and destination region is actually the same part of the same file.

2016-09-13f2fs: fix to set PageUptodate in f2fs_write_end correctlyJaegeuk Kim1-10/+19
Previously, f2fs_write_begin sets PageUptodate all the time. But, when user tries to update the entire page (i.e., len == PAGE_SIZE), we need to consider that the page is able to be copied partially afterwards. In such the case, we will lose the remaing region in the page. This patch fixes this by setting PageUptodate in f2fs_write_end as given copied result. In the short copy case, it returns zero to let generic_perform_write retry copying user data again. As a result, f2fs_write_end() works: PageUptodate len copied return retry 1. no 4096 4096 4096 false -> return 4096 2. no 4096 1024 0 true -> goto #1 case 3. yes 2048 2048 2048 false -> return 2048 4. yes 2048 1024 1024 false -> return 1024 Suggested-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2016-09-08f2fs: fix to detect temporary name of multimedia fileChao Yu1-4/+9
Some applications may create multimeida file with temporary name like '*.jpg.tmp' or '*.mp4.tmp', then rename to '*.jpg' or '*.mp4'. Now, f2fs can only detect multimedia filename with specified format: "filename + '.' + extension", so it will make f2fs missing to detect multimedia file with special temporary name, result in failing to set cold flag on file. This patch enhances detection flow for enabling lookup extension in the middle of temporary filename.

This patch enhances the xattr consistency of dirs from suddern power-cuts. Possible scenario would be: 1. dir->setxattr used by per-file encryption 2. file->setxattr goes into inline_xattr 3. file->fsync In that case, we should do checkpoint for #1.

2016-09-08f2fs: support async discardChao Yu4-2/+99

filename When creating new inode, security_inode_init_security will be called for initializing security info related to the inode, and filename is passed to security module, it helps security module such as SElinux to know which rule or label could be applied for the inode with specified name. Previously, if new inode is created as an encrypted one, f2fs will transfer encrypted filename to security module which may fail the check of security policy belong to the inode. So in order to this issue, alter to transfer original unencrypted filename instead. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Thread A Thread B - inode_lock fileA - inode_lock fileB - inode_lock fileA - inode_lock fileB We may encounter above potential deadlock during moving file range in concurrent scenario. This patch fixes the issue by using inode_trylock instead. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
