Akira Fujita 4a58579b9e ext4: Fix insufficient checks in EXT4_IOC_MOVE_EXT ... This patch fixes three problems in the handling of the EXT4_IOC_MOVE_EXT ioctl: 1. In current EXT4_IOC_MOVE_EXT, there are read access mode checks for original and donor files, but they allow the illegal write access to donor file, since donor file is overwritten by original file data. To fix this problem, change access mode checks of original (r->r/w) and donor (r->w) files. 2. Disallow the use of donor files that have a setuid or setgid bits. 3. Call mnt_want_write() and mnt_drop_write() before and after ext4_move_extents() calling to get write access to a mount.
