  "message": "ext3: Fix an overflow in ext3_trim_fs.\n\nIn a bs\u003d4096 volume, if we call FITRIM with the following parameter as\nfstrim_range(start \u003d 102400, len \u003d 134144000, minlen \u003d 10240), with the\nfollowing code:\nif (len \u003e\u003d EXT3_BLOCKS_PER_GROUP(sb))\n        len -\u003d (EXT3_BLOCKS_PER_GROUP(sb) - first_block);\nelse\n        last_block \u003d first_block + len;\n\nSo if len \u003c EXT3_BLOCKS_PER_GROUP while first_block + len \u003e\nEXT3_BLOCKS_PER_GROUP, last_block will be set to an overflow value\nwhich exceeds EXT3_BLOCKS_PER_GROUP.\n\nThis patch fixes it and adjusts len and last_block accordingly.\n\nCc: Lukas Czerner \u003clczerner@redhat.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Tao Ma \u003cboyu.mt@taobao.com\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n",
