749d14f782 target/hppa: Add emulation of a C3700 HP-PARISC workstation
This series adds a new PA-RISC machine emulation for the HP-PARISC
 C3700 workstation.
 
 The physical HP C3700 machine has a PA2.0 (64-bit) CPU, in contrast to
 the existing emulation of a B160L workstation which is a 32-bit only
 machine and where it's Dino PCI controller isn't 64-bit capable.
 
 With the HP C3700 machine emulation (together with the emulated Astro
 Memory controller and the Elroy PCI bridge) it's now possible to
 enhance the hppa CPU emulation to support the 64-bit instruction set
 in upcoming patches.

 v4 changes:
 - Fix testsuite error in astro by adding a realize() implementation
 
 v3 changes:
 based on feedback from BALATON Zoltan <balaton@eik.bme.hu>:
 - apply paches in different order to bring them logically closer to each other
 - update comments in lasips2
 - rephrased title and commit message of MAINTAINERS patch

d9cda21303 migration: simplify notifiers
Pass the callback function to add_migration_state_change_notifier so
that migration can initialize the notifier on add and clear it on
delete, which simplifies the call sites.  Shorten the function names
so the extra arg can be added more legibly.  Hide the global notifier
list in a new function migration_call_notifiers, and make it externally
visible so future live update code can call it.

No functional change.

1257065783 hw/net/rocker: Avoid variable length array
Replace an on-stack variable length array in of_dpa_ig() with
a g_autofree heap allocation.

The codebase has very few VLAs, and if we can get rid of them all we
can make the compiler error on new additions.  This is a defensive
measure against security bugs where an on-stack dynamic allocation
isn't correctly size-checked (e.g.  CVE-2021-3527).

2a6cb383e2 hw/net/fsl_etsec/rings.c: Avoid variable length array
In fill_rx_bd() we create a variable length array of size
etsec->rx_padding. In fact we know that this will never be
larger than 64 bytes, because rx_padding is set in rx_init_frame()
in a way that ensures it is only that large. Use a fixed sized
array and assert that it is big enough.

Since padd[] is now potentially rather larger than the actual
padding required, adjust the memset() we do on it to match the
size that we write with cpu_physical_memory_write(), rather than
clearing the entire array.

The codebase has very few VLAs, and if we can get rid of them all we

The assert() that checks for valid MTU sizes can be triggered by

e414270000 e1000e: Add ICR clearing by corresponding IMS bit
The datasheet does not say what happens when interrupt was asserted
(ICR.INT_ASSERT=1) and auto mask is *not* active.
However, section of 13.3.27 the PCIe* GbE Controllers Open Source
Software Developer’s Manual, which were written for older devices,
namely 631xESB/632xESB, 82563EB/82564EB, 82571EB/82572EI &
82573E/82573V/82573L, does say:
> If IMS = 0b, then the ICR register is always clear-on-read. If IMS is
> not 0b, but some ICR bit is set where the corresponding IMS bit is not
> set, then a read does not clear the ICR register. For example, if
> IMS = 10101010b and ICR = 01010101b, then a read to the ICR register
> does not clear it. If IMS = 10101010b and ICR = 0101011b, then a read
> to the ICR register clears it entirely (ICR.INT_ASSERTED = 1b).

Linux does no longer activate auto mask since commit
0a8047ac68e50e4ccbadcfc6b6b070805b976885 and the real hardware clears
ICR even in such a case so we also should do so.

4271f40383 virtio-net: correctly report maximum tx_queue_size value
Maximum value for tx_queue_size depends on the backend type.
1024 for vDPA/vhost-user, 256 for all the others.

The value is returned by virtio_net_max_tx_queue_size() to set the
parameter:

    n->net_conf.tx_queue_size = MIN(virtio_net_max_tx_queue_size(n),
                                    n->net_conf.tx_queue_size);

But the parameter checking uses VIRTQUEUE_MAX_SIZE (1024).

So the parameter is silently ignored and ethtool reports a different
value than the one provided by the user.

   ... -netdev tap,... -device virtio-net,tx_queue_size=1024

    # ethtool -g enp0s2
    Ring parameters for enp0s2:
    Pre-set maximums:
    RX:		256
    RX Mini:	n/a
    RX Jumbo:	n/a
    TX:		256
    Current hardware settings:
    RX:		256
    RX Mini:	n/a
    RX Jumbo:	n/a
    TX:		256

   ... -netdev vhost-user,... -device virtio-net,tx_queue_size=2048

    Invalid tx_queue_size (= 2048), must be a power of 2 between 256 and 1024

With this patch the correct maximum value is checked and displayed.

For vDPA/vhost-user:

    Invalid tx_queue_size (= 2048), must be a power of 2 between 256 and 1024

For all the others:

    Invalid tx_queue_size (= 512), must be a power of 2 between 256 and 256

ca3fcdeeee net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()
When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore
vhost_net pointer within the tap device state structure remains NULL. Hence,
assertion here on a NULL pointer return from tap_get_vhost_net() would not be
correct. Remove it and fix the crash generated by qemu upon initialization in
the following call chain :

qdev_realize() -> pci_qdev_realize() -> virtio_device_realize() ->
virtio_bus_device_plugged() -> virtio_net_get_features() -> get_vhost_net()

0b545b1e42 virtio-net: expose virtio_net_supported_guest_offloads()
To support restoring offloads state in vdpa, it is necessary to
expose the function virtio_net_supported_guest_offloads().

According to VirtIO standard, "Upon feature negotiation
corresponding offload gets enabled to preserve backward compatibility.".
Therefore, QEMU uses this function to get the device supported offloads.
This allows QEMU to know the device's defaults and skip the control
message sending if these defaults align with the driver's configuration.

Note that the device's defaults can mismatch the driver's configuration
only at live migration.

792676c165 rtl8139: fix large_send_mss divide-by-zero
If the driver sets large_send_mss to 0 then a divide-by-zero occurs.
Even if the division wasn't a problem, the for loop that emits MSS-sized
packets would never terminate.

Solve these issues by skipping offloading when large_send_mss=0.

This issue was found by OSS-Fuzz as part of Alexander Bulekov's device
fuzzing work. The reproducer is:

ad431f0f82 e1000e: Notify only new interrupts
In MSI-X mode, if there are interrupts already notified but not cleared
and a new interrupt arrives, e1000e incorrectly notifies the notified
ones again along with the new one.

To fix this issue, replace e1000e_update_interrupt_state() with
two new functions: e1000e_raise_interrupts() and
e1000e_lower_interrupts(). These functions don't only raise or lower
interrupts, but it also performs register writes which updates the
interrupt state. Before it performs a register write, these function
determines the interrupts already raised, and compares with the
interrupts raised after the register write to determine the interrupts
to notify.

The introduction of these functions made tracepoints which assumes that
the caller of e1000e_update_interrupt_state() performs register writes
obsolete. These tracepoints are now removed, and alternative ones are
added to the new functions.

dc9ef1bf45 igb: Always copy ethernet header
igb_receive_internal() used to check the iov length to determine
copy the iovs to a contiguous buffer, but the check is flawed in two
ways:
- It does not ensure that iovcnt > 0.
- It does not take virtio-net header into consideration.

The size of this copy is just 22 octets, which can be even less than
the code size required for checks. This (wrong) optimization is probably
not worth so just remove it. Removing this also allows igb to assume
aligned accesses for the ethernet header.

e209716749 igb: Do not require CTRL.VME for tx VLAN tagging
While the datasheet of e1000e says it checks CTRL.VME for tx VLAN
tagging, igb's datasheet has no such statements. It also says for
"CTRL.VLE":
> This register only affects the VLAN Strip in Rx it does not have any
> influence in the Tx path in the 82576.
(Appendix A. Changes from the 82575)

There is no "CTRL.VLE" so it is more likely that it is a mistake of
CTRL.VME.

ed447c60b3 igb: Fix Rx packet type encoding
igb's advanced descriptor uses a packet type encoding different from
one used in e1000e's extended descriptor. Fix the logic to encode
Rx packet type accordingly.

f3f9b726af e1000x: Fix BPRC and MPRC
Before this change, e1000 and the common code updated BPRC and MPRC
depending on the matched filter, but e1000e and igb decided to update
those counters by deriving the packet type independently. This
inconsistency caused a multicast packet to be counted twice.

Updating BPRC and MPRC depending on are fundamentally flawed anyway as
a filter can be used for different types of packets. For example, it is
possible to filter broadcast packets with MTA.

Always determine what counters to update by inspecting the packets.

This is intended to be followed by another change for the interface.
It also fixes the leak of memory mapping when the specified memory is
partially mapped.

8d689f6aae e1000e: Fix tx/rx counters
The bytes and packets counter registers are cleared on read.

Copying the "total counter" registers to the "good counter" registers has
side effects.
If the "total" register is never read by the OS, it only gets incremented.
This leads to exponential growth of the "good" register.

This commit increments the counters individually to avoid this.
