Ensure that we correctly handle racing invocations of the channel callback when the channel is being closed. We do this using the channel's inbound_lock. A side-effect of this strategy is that we avoid repeatedly picking up this lock as we drain the inbound ring-buffer. Signed-off-by:
-
K. Y. Srinivasan authored
When we close a channel, we set the corresponding callback function to NULL. Check before invoking the channel callback. Signed-off-by:

The current code was adjusting guest time in interrupt context; do this in process context since we may have to initiate cross-processor interrupts as part of setting time. Signed-off-by:

When we do get fatal errors from the host, offline the device since the host has already tried all possible recovery actions. Signed-off-by:

The current VHD handler on the Windows Host does not correctly handle INQUIRY and MODE_SENSE commands with some options. Fixup srb_status in these cases since the failure is not fatal. Signed-off-by:

Now, enable handling of all IDE devices by extending the storvsc device id table to handle IDE guid. As part of this cleanup Kconfig and Hyper-V Makefile to not build the IDE driver (blkvsc). Signed-off-by:
-
K. Y. Srinivasan authored
Add code to handle IDE devices using the storvsc driver. The storvsc_probe() is modified so that the storvsc driver can surface all disks presented to the guest as scsi devices using generic upper level Linux scsi drivers. Signed-off-by:

Get rid of the refcnt field in struct netvsc_device. We implement the following logic to manage the life cycle of the device: If the device is being destroyed, we do not allow any outgoing traffic. Furthermore, if the device is being destroyed, we allow incoming traffic only to drain outgoing traffic. Note that the driver may send some book keeping messages to the host not known to upper level Linux code. Signed-off-by:

Get rid of the reference counting in struct storvsc_device. We manage the lifecycle with the following logic: If the device is marked for destruction, we dot allow any outgoing traffic on the device. Incoming traffic is allowed only to drain pending outgoing traffic. Note that while the upper level code in Linux deals with outstanding I/Os, we may have situations on Hyper-V where some book keeping messages are sent out that the upper level Linux code may not be aware of.
