Hi! While investigating into the PR1782 I spent some time analyzing BasicAliasAnalysis.cpp. While the mentioned problem should be fixed now (I hope), I have discovered some other possibilities for a bug to occur. In the case of checking for aliasing of two pointer values, where at least one of them is a GEP instruction with out-of-bound indices, BasicAliasAnalysis can return NoAlias, even if the

This introduces vringh, which are generic accessors for virtio rings (host side). There's a host-side implementation in vhost, but it assumes that the rings are in userspace, and is tied to the vhost implementation. I have patches to adapt it to use vringh, but I'm pushing this in the next merge window for Sjur, who has CAIF patches which need it. This also includes a test program in

v1 -> v2: - Fixed everything mentioned in the review. Rich.

Somewhat invasive but mostly mechanical change to how plugins are called. This patch is in preparation for adding a second backend subtype for filters. Rich.

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix
