Subject: ptrace question
Date: Wed, 17 Oct 2001 09:23:38 -0700 [thread overview]
Message-ID: <GIEMIEJKPLDGHDJKJELAEEBLCNAA.rajeev_bector@yahoo.com> (raw)
I have a question on the ptrace system call
implementation:
In kernel/ptrace.c in the function access_one_page(),
why is read access denied to pages which are
marked PG_reserved ?
I have some pages in my driver which are reserved
and memory mapped to user applications which I'd
like to access in gdb.
Any clues to what is the risk if I were to enable
accessing of pages which are marked "reserved"
Thanks in advance !
Rajeev
