| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: compress: don't allow unaligned truncation on released compress inode\n\nf2fs image may be corrupted after below testcase:\n- mkfs.f2fs -O extra_attr,compression -f /dev/vdb\n- mount /dev/vdb /mnt/f2fs\n- touch /mnt/f2fs/file\n- f2fs_io setflags compression /mnt/f2fs/file\n- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=4\n- f2fs_io release_cblocks /mnt/f2fs/file\n- truncate -s 8192 /mnt/f2fs/file\n- umount /mnt/f2fs\n- fsck.f2fs /dev/vdb\n\n[ASSERT] (fsck_chk_inode_blk:1256) --> ino: 0x5 has i_blocks: 0x00000002, but has 0x3 blocks\n[FSCK] valid_block_count matching with CP [Fail] [0x4, 0x5]\n[FSCK] other corrupted bugs [Fail]\n\nThe reason is: partial truncation assume compressed inode has reserved\nblocks, after partial truncation, valid block count may change w/o\n.i_blocks and .total_valid_block_count update, result in corruption.\n\nThis patch only allow cluster size aligned truncation on released\ncompress inode for fixing." |
