Subject: [PATCH 0/2] Fix and re-enable vsyscall=emulate
Date: Mon, 7 Nov 2011 16:33:39 -0800 [thread overview]
Message-ID: <cover.1320712291.git.luto@amacapital.net> (raw)
In-Reply-To: <CALCETrXAiHs9PyziHBm-gZRiyahYafbxxUSxJUcFh=a-0th0EQ@mail.gmail.com>
The really nice fix (wiring up access_ok failures to be able to raise
signals) won't be ready on time for 3.2, so let's try the simpler fix
for now.
Changes from the earlier version:
- Clean up the odd ptr==0 check.
- Flip the default back to vsyscall=emulate
Andy Lutomirski (2):
x86-64: Set siginfo and context on vsyscall emulation faults
x86: Default to vsyscall=emulate
