However, since the device is already gone by the point we try to unregister the netdevice from the driver due to a hotplug we end up seeing that the netif isn't present and thus, forget to free any of the device IRQs. So: make sure that if we're in the process of dismantling the netdev, we always allow __igb_close() to be called so that IRQs may be freed normally. Additionally, only allow igb_close() to be called from __igb_close() if it hasn't already been called for the given adapter.

GCM can be invoked with a zero destination buffer. This is possible if the AAD and the ciphertext have zero lengths and only the tag exists in the source buffer (i.e. a source buffer cannot be zero). In this case, the GCM cipher only performs the authentication and no decryption operation. When the destination buffer has zero length, it is possible that no page is mapped to the SG pointing to the destination. In this case, sg_page(req->dst) is an invalid access. Therefore, page accesses should only be allowed if the req->dst->length is non-zero which is the indicator that a page must exist. This fixes a crash that can be triggered by user space via AF_ALG.
