<div dir="ltr">Hi list<div><br></div><div>I'm using strace running in Ubuntu on a Samsung ARM chromebook. It's using the 3.4.0 kernel from here: <a href="http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git">http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git</a> (the one the comes with Chrome OS).</div>
<div><br></div><div>When I run a program that is executed via strace, I see a lot of "stray syscall entry/exit" messages, and the paths of the filenames reported by the -eopen filter aren't present. I'm attaching the full output of "strace ls" to this mail. Here's a snippet of the output. I've cut away all of the "pid <pid> stray syscall [...]" messages from this snipped. 332 lines out of the 513 line output are "stray syscall" messages.</div>
