Subject: Q: a bogus set_fs(USER_DS) in setup_frame/setup_rt_frame ?
Date: Tue, 17 Jul 2007 19:46:38 +0400 [thread overview]
Message-ID: <20070717154638.GA342@tv-sign.ru> (raw)
I am really puzzled by set_fs(USER_DS) in setup_frame/setup_rt_frame.
How is it possible that current->addr_limit != USER_DS ? If this _is_
possible, how can can we trust the result of access_ok() above?
Thanks in advance,
Oleg.
