Proper Subject prefix here would be "tcp: ", not "net: "
and maybe adjust the subject line to also mention the
specific function being fixed, which in this case would
be tcp_parse_options().  So:

	tcp: Validate length of data before dereference in tcp_parse_options().

and then you can make the commit message just be your signoff.
