vhost-vsock: fix orphan connection reset

2016-12-09T02:24:30Z

local_addr.svm_cid is host cid. We should check guest cid instead, which is remote_addr.svm_cid. Otherwise we end up resetting all connections to all guests. Cc: stable@vger.kernel.org [4.8+] Reviewed-by: Stefan Hajnoczi Signed-off-by: Peng Tao Signed-off-by: David S. Miller

miscdevice: Add helper macro for misc device boilerplate

2016-08-31T12:12:35Z

Many modules call misc_register and misc_deregister in its module init and exit methods without any additional code. This ends up being boilerplate. This patch adds helper macro module_misc_device(), that replaces module_init()/ module_exit() with template functions. This patch also converts drivers to use new macro. Change since v1: Add device.h include in miscdevice.h as module_driver macro was not available from other include files in some architectures.

vhost/scsi: fix reuse of &vq->iov[out] in response

2016-08-23T14:16:57Z

The address of the iovec &vq->iov[out] is not guaranteed to contain the scsi command's response iovec throughout the lifetime of the command. Rather, it is more likely to contain an iovec from an immediately following command after looping back around to vhost_get_vq_desc(). Pass along the iovec entirely instead.

vhost/vsock: fix vhost virtio_vsock_pkt use-after-free

2016-08-09T10:42:37Z

Stash the packet length in a local variable before handing over ownership of the packet to virtio_transport_recv_pkt() or virtio_transport_free_pkt(). This patch solves the use-after-free since pkt is no longer guaranteed to be alive. Reported-by: Dan Carpenter Signed-off-by: Stefan Hajnoczi Signed-off-by: Michael S. Tsirkin

VSOCK: Use kvfree()

vhost: split out vringh Kconfig

2016-08-02T13:54:28Z

vringh is pulled in by caif and mic, but the other vhost config does not need to be there. In particular, it makes no sense to have vhost net/scsi/sock under caif/mic. Create a separate Kconfig file and put vringh bits there. Signed-off-by: Michael S. Tsirkin
