Description
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: cancle set bad inode after removing name fails
The reproducer uses a file0 on a ntfs3 file system with a corrupted i_link.
When renaming, the file0's inode is marked as a bad inode because the file
name cannot be deleted.
The underlying bug is that make_bad_inode() is called on a live inode.
In some cases it's "icache lookup finds a normal inode, d_splice_alias()
is called to attach it to dentry, while another thread decides to call
make_bad_inode() on it - that would evict it from icache, but we'd already
found it there earlier".
In some it's outright "we have an inode attached to dentry - that's how we
got it in the first place; let's call make_bad_inode() on it just for shits
and giggles".
