kernel: ext4: make sure the first directory block is not a hole

The syzbot constructs a directory that has no dirblock but is non-inline, i.e. the first directory block is a hole. And no errors are reported when creating files in this directory. Then, we get a directory block without '.' and '..' but with a valid dentry. This may cause some code that relies o...

CVE-2024-42304

In CVE-2024-42304, the Linux kernel ext4 filesystem had a hole-handling bug: if the first directory block is a hole (no dirblock) but a valid dentry exists, code relying on "."/".." could crash. The fix is to report filesystem corruption and return an error when ext4_read_dirblock() detects a hol...
