Discovered by Atuin - Automated Vulnerability Discovery Engine. Reject DataReply payload lengths that cannot fit in recv_dless_read()'s signed size argument so a bogus remote peer cannot wrap the length negative and turn it into a huge heap OOB-write. Fixes: b411b36 ("The DRBD driver") Cc: stable@vger.kernel.org Signed-off-by: Tianchu Chen <flynnnchen@tencent.com>
