Hi: This series tries to fix various issues of vhost: - Patch 1 adds a missing write barrier between used idx updating and logging. - Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries. - Patch 4 fixes the diry page logging when device IOTLB is enabled. We should done through GPA instead of GIOVA, this was done through logging through iovec and traversing GPA->HPA list for the GPA. Please consider them for -stable. Thanks Jason Wang (4): vhost: make sure used idx is seen before log in vhost_add_used_n() vhost_net: rework on the lock ordering for busy polling Revert "net: vhost: lock the vqs one by one" vhost: log dirty page correctly drivers/vhost/net.c | 21 +++++++-- drivers/vhost/vhost.c | 101 ++++++++++++++++++++++++++++++++++-------- drivers/vhost/vhost.h | 3 +- 3 files changed, 102 insertions(+), 23 deletions(-) -- 2.17.1
