From: Victor van der Veen To: linux-kernel@vger.kernel.org Content-Type: text/plain; charset="UTF-8" Date: Tue, 30 Nov 2010 12:47:40 +0100 Message-ID: <1291117660.3206.11.camel@D430> Mime-Version: 1.0 X-Mailer: Evolution 2.30.3 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, - When was ASLR introduced in the Linux kernel (not PaX/ExecShield)? - When was ASLR enabled by default? - What's the current state of ASLR in the Linux kernel? Is it still under development? Or should we rely on the PaX/ExecShield patches? Wikipedia states that "a weak form of ASLR exists in the linux kernel since version 2.6.12 (June 2005)", but I could not find any proof that backs this up. I grepped changelogs of the entire 2.6 kernel, but I was unable to find any relevant information. Grepping the source code did not help either. Any more Google results all quote the same wikipedia line. Thanks, Victor van der Veen
