Pull networking fixes from Jakub Kicinski:
"Cross-tree/merge window issues:
- rtl8150: don't incorrectly assign random MAC addresses; fix late in
the 5.9 cycle started depending on a return code from a function
which changed with the 5.10 PR from the usb subsystem
Current release regressions:
- Revert "virtio-net: ethtool configurable RXCSUM", it was causing
crashes at probe when control vq was not negotiated/available
Previous release regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
bus, only first device would be probed correctly
- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu() to
synchronize_rcu_expedited()
- netsec: ignore 'phy-mode' device property on ACPI systems; the
property is not populated correctly by the firmware, but firmware
configures the PHY so just keep boot settings
Previous releases - always broken:
- tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
bulk transfers getting "stuck"
- icmp: randomize the global rate limiter to prevent attackers from
getting useful signal
- r8169: fix operation under forced interrupt threading, make the
driver always use hard irqs, even on RT, given the handler is light
and only wants to schedule napi (and do so through a _irqoff()
variant, preferably)
- bpf: Enforce pointer id generation for all may-be-null register
type to avoid pointers erroneously getting marked as null-checked
- tipc: re-configure queue limit for broadcast link
- net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
tunnels
- fix various issues in chelsio inline tls driver
Misc:
- bpf: improve just-added bpf_redirect_neigh() helper api to support
supplying nexthop by the caller - in case BPF program has already
done a lookup we can avoid doing another one
- remove unnecessary break statements

Pull clk updates from Stephen Boyd:
"This contains no changes to the core framework. It is a collection of
various clk driver updates.
The biggest driver updates in terms of lines of code is the Allwinner
driver, closely followed by the Qualcomm and Mediatek drivers. All of
those hit high because we add so many lines of clk data. Coming in
fourth place is i.MX which also adds a bunch of clk data. This
accounts for the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for
various clk drivers that have baked in linux-next for a while. I
suppose one highlight or theme is that more clk drivers are being
updated to work as modules, which is interesting to see such critical
SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being
dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module

This driver calls ether_setup to set up the network device.
The ether_setup function would add the IFF_TX_SKB_SHARING flag to the
device. This flag indicates that it is safe to transmit shared skbs to
the device.
However, this is not true. This driver may pad the frame (in eth_tx)
before transmission, so the skb may be modified.

The hdlc_rcv function is used as hdlc_packet_type.func to process any
skb received in the kernel with skb->protocol == htons(ETH_P_HDLC).
The purpose of this function is to provide second-stage processing for
skbs not assigned a "real" L3 skb->protocol value in the first stage.
This function assumes the device from which the skb is received is an
HDLC device (a device created by this module). It assumes that
netdev_priv(dev) returns a pointer to "struct hdlc_device".
However, it is possible that some driver in the kernel (not necessarily
in our control) submits a received skb with skb->protocol ==
htons(ETH_P_HDLC), from a non-HDLC device. In this case, the skb would
still be received by hdlc_rcv. This will cause problems.
hdlc_rcv should be able to recognize and drop invalid skbs. It should
first make sure "dev" is actually an HDLC device, before starting its
processing. This patch adds this check to hdlc_rcv.

The pci_save_state() call in vmd_suspend() can be performed by
pci_pm_suspend_irq(). This also allows VMD to benefit from the call into
pci_prepare_to_sleep().
The pci_restore_state() call in vmd_resume() was restoring state after
pci_pm_resume()::pci_restore_standard_config() had already restored state.
It's also been suspected that the config state should have been restored
before re-requesting IRQs instead of afterwards.
Remove the pci_save_state()/pci_restore_state() calls in
vmd_suspend()/vmd_resume() to allow proper flow through generic PCI core
Power Management code.

If riov and wiov are both defined and they point to different
objects, only riov is initialized. If the wiov is not initialized
by the caller, the function fails returning -EINVAL and printing
"Readable desc 0x... after writable" error message.
This issue happens when descriptors have both readable and writable
buffers (eg. virtio-blk devices has virtio_blk_outhdr in the readable
buffer and status as last byte of writable buffer) and we call
__vringh_iov() to get both type of buffers in two different iovecs.
Let's replace the 'else if' clause with 'if' to initialize both
riov and wiov if they are not NULL.
As checkpatch pointed out, we also avoid crashing the kernel
when riov and wiov are both NULL, replacing BUG() with WARN_ON()
and returning -EINVAL.

set_map() is used by mlx5 vdpa to create a memory region based on the
address map passed by the iotlb argument. If we get successive calls, we
will destroy the current memory region and build another one based on
the new address mapping. We also need to setup the hardware resources
since they depend on the memory region.
If these calls happen before DRIVER_OK, It means that driver VQs may
also not been setup and we may not create them yet. In this case we want
to avoid setting up the other resources and defer this till we get
DRIVER OK.

An architecture may restrict host access to guest memory,
e.g. IBM s390 Secure Execution or AMD SEV.
Provide a new Kconfig entry the architecture can select,
CONFIG_ARCH_HAS_RESTRICTED_VIRTIO_MEMORY_ACCESS, when it provides
the arch_has_restricted_virtio_memory_access callback to advertise
to VIRTIO common code when the architecture restricts memory access
from the host.
The common code can then fail the probe for any device where
VIRTIO_F_ACCESS_PLATFORM is required, but not set.
