Date: Wed, 22 Oct 2014 14:08:52 +0100 From: David Vrabel <david.vrabel@...rix.com> To: <netdev@...r.kernel.org> CC: David Vrabel <david.vrabel@...rix.com>, <xen-devel@...ts.xenproject.org>, Ian Campbell <ian.campbell@...rix.com>, Wei Liu <wei.liu2@...rix.com> Subject: [PATCHv1 0/3 net-next] xen-netback: guest Rx queue drain and stall fixes This series fixes two critical xen-netback bugs. 1. Netback may consume all of host memory by queuing an unlimited number of skb on the internal guest Rx queue. This behaviour is guest triggerable. 2. Carrier flapping under high traffic rates which reduces performance. The first patch is a prerequite. Removing support for frontends with feature-rx-notify makes it easier to reason about the correctness of netback since it no longer has to support this outdated and broken mode.
