Subject: Re: Non-Exec stack patches
Date: Wed, 14 Apr 2004 10:47:02 +0100 [thread overview]
Message-ID: <20040414094702.GC8888@mail.shareable.org> (raw)
In-Reply-To: <9AB83E4717F13F419BD880F5254709E5011EBABA@scsmsx402.sc.intel.com>
People looking at PROT_EXEC page table flags might want to be aware
that <asm-um/pgtable.h> mimics the behaviour of i386: read implies and
is implied by exec, write implies read.
That might mean user-mode linux doesn't provide no-exec-stack
protection even when the underlying kernel does offer it. I'm not sure.
