Subject: [PATCH 0/2] Fixes and cleanups in PTRACE_SETOPTIONS
Date: Fri, 9 Sep 2011 08:22:30 +0200 [thread overview]
Message-ID: <201109090822.30063.vda.linux@googlemail.com> (raw)
This patchset has two changes.
First patch makes ptrace(PTRACE_SETOPTIONS, pid, 0, <bogus value>)
to error out *without* changing any task->ptrace bits.
Second patch is a cleanup: PTRACE_SETOPTIONS code
clears all option bits in task->ptrace, then sets bits one-by-one.
This is butt-ugly.
