| In the Linux kernel, the following vulnerability has been resolved:
xfs: fix exchange-range-to-eof file size exchange
Norbert Szetei posted a patch containing an incomplete description of a
bug in XFS_IOC_EXCHANGE_RANGE's TO_EOF flag. The bug tricks
exchange-range into modifying a file so that it has shared blocks
starting beyond EOF, which is never allowed because files never have
written data beyond EOF, and you can only share written data blocks.
This is key to all the incorrect behavior that follows.
Eventually I got from Norbert a description of what's going wrong:

> that gets rewritten and file1 is the one that ends up with the flag

So yes, TO_EOF is screwing up the file size even if it's actually
exchanging the data block correctly. The following is the intended
behavior of XFS_EXCHANGE_RANGE_TO_EOF, as described by its manpage:
"Ignore the length parameter. All bytes in file1_fd from file1_offset
to EOF are moved to file2_fd, and file2's size is set to
(file2_offset+(file1_length-file1_offset)). Meanwhile, all bytes in
file2 from file2_offset to EOF are moved to file1 and file1's size is
set to (file1_offset+(file2_length-file2_offset))."
In other words, if we only exchange a portion of the file data, then we
should only exchange the portion of the file size that relates to the
exchanged data. Unfortunately, the code swaps the ondisk file size and
the incore file sizes, which is incorrect if the caller passes in a
nonzero offset.
Having confused the file sizes, the PoC uses a second exchange-range
call on what looks like a non-reflinked single-block file. Because the
file size is set incorrectly, exchange-range thinks it's exchanging the
full contents of two files and clears the reflink flag on the broken
file. That enables an extending write of the broken file to rewrite the
shared block that's just past EOF. This has become known colloquially
as refluxfs.
Once the file sizes are set correctly, the second exchange-range no
longer thinks that it's doing a full-contents swap, so it won't clear
the reflink flag on either of its file arguments.
Norbert followed up to an earlier version of this patch with a second
complaint about us not handling the i_disk_size state correctly:
> The offsets are bounded against the incore i_size but subtracted from
>
