"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix f2fs_bug_on when uninstalling filesystem call f2fs_evict_inode.\n\ncreating a large files during checkpoint disable until it runs out of\nspace and then delete it, then remount to enable checkpoint again, and\nthen unmount the filesystem triggers the f2fs_bug_on as below:\n\n------------[ cut here ]------------\nkernel BUG at fs/f2fs/inode.c:896!\nCPU: 2 UID: 0 PID: 1286 Comm: umount Not tainted 6.11.0-rc7-dirty #360\nOops: invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\nRIP: 0010:f2fs_evict_inode+0x58c/0x610\nCall Trace:\n __die_body+0x15/0x60\n die+0x33/0x50\n do_trap+0x10a/0x120\n f2fs_evict_inode+0x58c/0x610\n do_error_trap+0x60/0x80\n f2fs_evict_inode+0x58c/0x610\n exc_invalid_op+0x53/0x60\n f2fs_evict_inode+0x58c/0x610\n asm_exc_invalid_op+0x16/0x20\n f2fs_evict_inode+0x58c/0x610\n evict+0x101/0x260\n dispose_list+0x30/0x50\n evict_inodes+0x140/0x190\n generic_shutdown_super+0x2f/0x150\n kill_block_super+0x11/0x40\n kill_f2fs_super+0x7d/0x140\n deactivate_locked_super+0x2a/0x70\n cleanup_mnt+0xb3/0x140\n task_work_run+0x61/0x90\n\nThe root cause is: creating large files during disable checkpoint\nperiod results in not enough free segments, so when writing back root\ninode will failed in f2fs_enable_checkpoint. When umount the file\nsystem after enabling checkpoint, the root inode is dirty in\nf2fs_evict_inode function, which triggers BUG_ON. The steps to\nreproduce are as follows:\n\ndd if=/dev/zero of=f2fs.img bs=1M count=55\nmount f2fs.img f2fs_dir -o checkpoint=disable:10%\ndd if=/dev/zero of=big bs=1M count=50\nsync\nrm big\nmount -o remount,checkpoint=enable f2fs_dir\numount f2fs_dir\n\nLet's redirty inode when there is not free segments during checkpoint\nis disable."
