commit 4abc996 upstream. Syzkaller managed to trigger concurrent calls to kernfs_remove_by_name_ns() for the same file resulting in a KASAN detected use-after-free. The race occurs when the root node is freed during kernfs_drain(). To prevent this acquire an additional reference for the root of the tree that is removed before calling __kernfs_remove(). Found by syzkaller with the following reproducer (slab_nomerge is required): syz_mount_image$ext4(0x0, &(0x7f0000000100)='./file0\x00', 0x100000, 0x0, 0x0, 0x0, 0x0) r0 = openat(0xffffffffffffff9c,

commit 98bea25 upstream. Log load and replay is part of the metadata handle flow during mount operation. The $MFT record will be loaded and used while replaying logs. However, a malformed $MFT record, say, has RECORD_FLAG_DIR flag set and contains an ATTR_ROOT attribute will misguide kernel to treat it as a directory, and try to free the allocated resources when the corresponding inode is freed, which will cause an invalid kfree because the memory hasn't actually been allocated.
