Subject: [Qemu-devel] RFC: [0/11] EFAULT patch
Date: Tue, 18 Sep 2007 20:59:12 -0400 (EDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0709182050320.20150@trantor.stuart.netsweng.com> (raw)
Following this message, are the 11 parts of the patch that implements
EFAULT detection in the linux-user mode. Hopefully, this reflects what
was discussed following the first RFC of this patch. Also, hopefully, it
is easier to digest in smaller pieces like this.
In short, the (un)lock_user*() interfaces have been replaced by access_ok
and copy_(to|from)_user() style interfaces. This code should now look
more like some of the 32_on_64 code in the Linux kernel.
As a side effect of these changes, and the more thorough testing that
went along with them, several other bugs have been fixed in areas such
as IPC and sockets.
As before, the Linux Test Project test suite was used in an armel on
x86_64 environment.
Your comments would be appreciated as I'd like to finish beating these
changes into shape so they can be accepted into the repository.
