Subject: [PATCH 0/9] strict user copy checks on x86_64
Date: Thu, 12 May 2011 16:50:03 -0700 [thread overview]
Message-ID: <1305244212-19183-1-git-send-email-sboyd@codeaurora.org> (raw)
It turns out that strict user copy checks (also known as
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS) isn't actually implemented
on x86_64 and thus we aren't catching potential security holes
at compile time.
This series adds support for strict user copy checks on x86_64
and silences all the benign warnings in the x86_64 allyesconfig.
The final patch consolidates the config option as its duplicated
across mutliple arches. I don't know what tree this series should
go through so I tried to send the individual driver patches to the
respective maintainers.
