SubjectRe: Stack growing and buffer overflows
The OpenBSD guys have been working on closing  buffer overflow holes.
Slashdot has this pointer to a msg from Theo de Raadt:

In the last while, a couple of people in OpenBSD have
been putting some buffer overflow "solutions" into our
source tree; under my continual prodding. I thought I
would summarize some of these and how they fit together,
since what I have seen written up so far has been
wildly inaccurate. (Bad reporter, no cookie).

These are, in short form:

1) PROT_* purity
2) W^X
3) .rodata
4) propolice


I like the idea of turning off execute permission on the stack pages.
