Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
virtio_net: Fix error unwinding of XDP initialization<br />
<br />
When initializing XDP in virtnet_open(), some rq xdp initialization<br />
may hit an error causing net device open failed. However, previous<br />
rqs have already initialized XDP and enabled NAPI, which is not the<br />
expected behavior. Need to roll back the previous rq initialization<br />
to avoid leaks in error unwinding of init code.<br />
<br />
Also extract helper functions of disable and enable queue pairs.<br />
Use newly introduced disable helper function in error unwinding and<br />
virtnet_close. Use enable helper function in virtnet_open.
