Subject: [PATCH] kprobe: kprobe-booster fix for NX support on i386
Date: Wed, 01 Mar 2006 04:41:00 -0000 [thread overview]
Message-ID: <440525CD.4090505@sdl.hitachi.co.jp> (raw)
In-Reply-To: <4403E894.4050300@sdl.hitachi.co.jp>
Hi, Andrew
Here is the patch to fix kprobe-booster against linux-2.6.16-rc5-mm1.
- Fix to assign the correct address of the instruction buffer.
From linux-2.6.16-rc5, the ainsn.insn on i386 arch became a pointer
instead of an array itself.
Best regards,
