Subject: [gentoo-dev] Porting PaX to the amd64

1 Quote from the PaX docs.

3 The goal of the PaX project is to research various defense mechanisms
4 against the exploitation of software bugs that give an attacker
5 arbitrary read/write access to the attacked task's address space. This
6 class of bugs contains among others various forms of buffer overflow
7 bugs (be they stack or heap based), user supplied format string bugs,
8 etc.

11 If you have an amd64 and your bold, brave and want to be on the bleeding
12 edge of security solutions then your in luck. The PaX Team has come up
13 with an experimental patch for the amd64 that needs some testing
14 from a few somebody's that own or have root access to amd64
16 Grab yourself these three files to begin testing.

21 unpack the kernel
22 tar jxvf linux-2.4.22.tar.bz2
23 add the pax-linux-2.4.22-200308271615.patch
24 add the pax-linux-2.4.22.patch.amd64
26 Enable pax in your kernel with as many options as your willing to help
27 test.
29 Compile the kernel
31 # make menuconfig
32 # make dep bzImage modules modules_install
33 tell your bootloader to use the arch/amd64/bzImage file
35 reboot and report success/failures via email to pageexec@××××××××.hu and
36 or real-time on in #pax
