The cadence UART attempts to avoid allowing the guest to set invalid
baud rate register values in the uart_write() function. However it
does the "mask to the size of the register field" and "check for
invalid values" in the wrong order, which means that a malicious
guest can get a bogus value into the register by setting also some
high bits in the value, and cause QEMU to crash by division-by-zero.
Do the mask before the bounds check instead of afterwards.

A Linux guest will perform IRQ migration after the IRQ has happened,
updating the RTE to point to the new destination CPU and then unmasking
the interrupt.
However, when the guest updates the RTE, ioapic_mem_write() calls
ioapic_service(), which redelivers the pending level interrupt via
kvm_set_irq(), *before* calling ioapic_update_kvm_routes() which sets
the new target CPU.
Thus, the IRQ which is supposed to go to the new target CPU is instead
misdelivered to the previous target. An example where the guest kernel
is attempting to migrate from CPU#2 to CPU#0 shows:

There are no other code paths in ioapic_mem_write() which need the KVM
IRQ routing table to be updated, so just shift the call from the end
of the function to happen right before the call to ioapic_service()
and thus deliver the re-enabled IRQ to the right place.
Alternative fixes might have been just to remove the part in
ioapic_service() which delivers the IRQ via kvm_set_irq() because
surely delivering as MSI ought to work just fine anyway in all cases?
That code lacks a comment justifying its existence.
Or maybe in the specific case shown in the above log, it would have
sufficed for ioapic_update_kvm_routes() to update the route *even*
when the IRQ is masked. It's not like it's actually going to get
triggered unless QEMU deliberately does so, anyway? But that only
works because the target CPU happens to be in the high word of the
RTE; if something in the *low* word (vector, perhaps) was changed
at the same time as the unmask, we'd still trigger with stale data.

The values returned by eth_get_protocols() are used to perform RSS,
checksumming and segmentation. Even when a packet signals the use of the
protocols which these operations can be applied to, the headers for them
may not be present because of too short packet or fragmentation, for
example. In such a case, the operations cannot be applied safely.
Report the presence of headers instead of whether the use of the
protocols are indicated with eth_get_protocols(). This also makes
corresponding changes to the callers of eth_get_protocols() to match
with its new signature and to remove redundant checks for fragmentation.

of generated interrupts. This also removes the need of

change, and net_tx_pkt relied solely on IPv4 fragmentation. Not only
this is not aligned with the specification, but it also resulted in

e1000e didn't perform software segmentation for loopback if virtio-net
header is enabled, which is wrong.
To fix the problem, introduce net_tx_pkt_send_custom(), which allows the
caller to specify whether offloading should be assumed or not.
net_tx_pkt_send_custom() also allows the caller to provide a custom
sending function. Packets with virtio-net headers and ones without
virtio-net headers will be provided at the same time so the function
can choose the preferred version. In case of e1000e loopback, it prefers
to have virtio-net headers as they allows to skip the checksum
verification if VIRTIO_NET_HDR_F_DATA_VALID is set.

Use memcpy instead of memmove to initialize registers. The initial
register templates and register table instances will never overlap.

When a register has effective bits fewer than their width, the old code
inconsistently masked when writing or reading. Make the code consistent
by always masking when writing, and remove some code duplication.
