net: Fix two use-after-free bugs

The two patches fix two use-after-free bugs related to cleaning up
network namespaces, one in sit and one in ip6_tunnel. They are easy to
trigger if the user has the ability to create network namespaces.

The bugs can be used to trigger null pointer dereferences. I am not
sure if they can be exploited further, but I would guess that they
can. I am not sending them to the mailing list without confirmation
that doing so would be OK.

941ea91e87 net: ip6_tunnel: Unregister catch-all devices
Similarly to the sit case, we need to remove the tunnels with no
addresses that have been moved to another network namespace.

610f8c0fc8 net: sit: Unregister catch-all devices
A sit interface created without a local or a remote address is linked
into the `sit_net::tunnels_wc` list of its original namespace. When
deleting a network namespace, delete the devices that have been moved.

The following script triggers a null pointer dereference if devices
linked in a deleted `sit_net` remain:

    for i in `seq 1 30`; do
        ip netns add ns-test
        ip netns exec ns-test ip link add dev veth0 type veth peer veth1
        ip netns exec ns-test ip link add dev sit$i type sit dev veth0
        ip netns exec ns-test ip link set dev sit$i netns $$
        ip netns del ns-test
    done
    for i in `seq 1 30`; do
        ip link del dev sit$i
    done

1fe976d308 net: phy: marvell: fix detection of PHY on Topaz switches
Since commit fee2d54641 ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.

This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.

This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.

Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.

Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.

Prior this change Topaz's internal PHY is detected by kernel as:

  PHY [...] driver [Marvell 88E6390] (irq=63)

And afterwards as:

  PHY [...] driver [Marvell 88E6341 Family] (irq=63)

d163a925eb netfilter: arp_tables: add pre_exit hook for table unregister
Same problem that also existed in iptables/ip(6)tables, when
arptable_filter is removed there is no longer a wait period before the
table/ruleset is free'd.

Unregister the hook in pre_exit, then remove the table in the exit
function.
This used to work correctly because the old nf_hook_unregister API
did unconditional synchronize_net.

The per-net hook unregister function uses call_rcu instead.

7ee3c61dcd netfilter: bridge: add pre_exit hooks for ebtable unregistration
Just like ip/ip6/arptables, the hooks have to be removed, then
synchronize_rcu() has to be called to make sure no more packets are being
processed before the ruleset data is released.

Place the hook unregistration in the pre_exit hook, then call the new
ebtables pre_exit function from there.

Years ago, when first netns support got added for netfilter+ebtables,
this used an older (now removed) netfilter hook unregister API, that did
a unconditional synchronize_rcu().

Now that all is done with call_rcu, ebtable_{filter,nat,broute} pernet exit
handlers may free the ebtable ruleset while packets are still in flight.

This can only happens on module removal, not during netns exit.

The new function expects the table name, not the table struct.

This is because upcoming patch set (targeting -next) will remove all
net->xt.{nat,filter,broute}_table instances, this makes it necessary
to avoid external references to those member variables.

The existing APIs will be converted, so follow the upcoming scheme of
passing name + hook type instead.

27f0ad7169 net: fix hangup on napi_disable for threaded napi
napi_disable() is subject to an hangup, when the threaded
mode is enabled and the napi is under heavy traffic.

If the relevant napi has been scheduled and the napi_disable()
kicks in before the next napi_threaded_wait() completes - so
that the latter quits due to the napi_disable_pending() condition,
the existing code leaves the NAPI_STATE_SCHED bit set and the
napi_disable() loop waiting for such bit will hang.

This patch addresses the issue by dropping the NAPI_STATE_DISABLE
bit test in napi_thread_wait(). The later napi_threaded_poll()
iteration will take care of clearing the NAPI_STATE_SCHED.

This also addresses a related problem reported by Jakub:
before this patch a napi_disable()/napi_enable() pair killed
the napi thread, effectively disabling the threaded mode.
On the patched kernel napi_disable() simply stops scheduling
the relevant thread.

v1 -> v2:
  - let the main napi_thread_poll() loop clear the SCHED bit

3bc41d6d27 lan743x: fix ethernet frame cutoff issue
The ethernet frame length is calculated incorrectly. Depending on
the value of RX_HEAD_PADDING, this may result in ethernet frames
that are too short (cut off at the end), or too long (garbage added
to the end).

Fix by calculating the ethernet frame length correctly. For added
clarity, use the ETH_FCS_LEN constant in the calculation.

Many thanks to Heiner Kallweit for suggesting this solution.

d473d32c2f of: property: fw_devlink: do not link ".*,nr-gpios"
[<vendor>,]nr-gpios property is used by some GPIO drivers[0] to indicate
the number of GPIOs present on a system, not define a GPIO. nr-gpios is
not configured by #gpio-cells and can't be parsed along with other
"*-gpios" properties.

nr-gpios without the "<vendor>," prefix is not allowed by the DT
spec[1], so only add exception for the ",nr-gpios" suffix and let the
error message continue being printed for non-compliant implementations.

[0] nr-gpios is referenced in Documentation/devicetree/bindings/gpio:
 - gpio-adnp.txt
 - gpio-xgene-sb.txt
 - gpio-xlp.txt

bc04d93ea3 vdpa/mlx5: Fix suspend/resume index restoration
When we suspend the VM, the VDPA interface will be reset. When the VM is
resumed again, clear_virtqueues() will clear the available and used
indices resulting in hardware virqtqueue objects becoming out of sync.
We can avoid this function alltogether since qemu will clear them if
required, e.g. when the VM went through a reboot.

Moreover, since the hw available and used indices should always be
identical on query and should be restored to the same value same value
for virtqueues that complete in order, we set the single value provided
by set_vq_state(). In get_vq_state() we return the value of hardware
used index.

When feature VIRTIO_NET_F_MTU is negotiated on mlx5_vdpa,
22 extra bytes worth of MTU length is shown in guest.
This is because the mlx5_query_port_max_mtu API returns
the "hardware" MTU value, which does not just contain the
 Ethernet payload, but includes extra lengths starting
from the Ethernet header up to the FCS altogether.

Fix the MTU so packets won't get dropped silently.

drivers/usb/core/hub.c: usb_new_device() contains the following:

        /* By default, forbid autosuspend for all devices.  It will be
         * allowed for hubs during binding.
         */
        usb_disable_autosuspend(udev);

So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.

This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.

This reverts commit 7bd9fb058d.

2d1b50abf8 Merge branch 'lantiq-GSWIP-fixes'
Martin Blumenstingl says:

====================
lantiq: GSWIP: two more fixes

after my last patch got accepted and is now in net as commit
3e6fdeb28f ("net: dsa: lantiq_gswip: Let GSWIP automatically set
the xMII clock") [0] some more people from the OpenWrt community
(many thanks to everyone involved) helped test the GSWIP driver: [1]

It turns out that the previous fix does not work for all boards.
There's no regression, but it doesn't fix as many problems as I
thought. This is why two more fixes are needed:
- the first one solves many (four known but probably there are
  a few extra hidden ones) reported bugs with the GSWIP where no
  traffic would flow. Not all circumstances are fully understood
  but testing shows that switching away from PHY auto polling
  solves all of them
- while investigating the different problems which are addressed
  by the first patch some small issues with the existing code were
  found. These are addressed by the second patch

Changes since v1 at [0]:
- Don't configure the link parameters in gswip_phylink_mac_config
  (as we're using the "modern" way in gswip_phylink_mac_link_up).
  Thanks to Andrew for the hint with the phylink documentation.
- Clarify that GSWIP_MII_CFG_RMII_CLK is ignored by the hardware in
  the description of the second patch as suggested by Hauke
- Don't set GSWIP_MII_CFG_RGMII_IBS in the second patch as we don't
  have any hardware available for testing this. The patch
  description now also reflects this.
- Added Andrew's Reviewed-by to the first patch (thank you!)

4b5923249b net: dsa: lantiq_gswip: Configure all remaining GSWIP_MII_CFG bits
There are a few more bits in the GSWIP_MII_CFG register for which we
did rely on the boot-loader (or the hardware defaults) to set them up
properly.

For some external RMII PHYs we need to select the GSWIP_MII_CFG_RMII_CLK
bit and also we should un-set it for non-RMII PHYs. The
GSWIP_MII_CFG_RMII_CLK bit is ignored for other PHY connection modes.

The GSWIP IP also supports in-band auto-negotiation for RGMII PHYs when
the GSWIP_MII_CFG_RGMII_IBS bit is set. Clear this bit always as there's
no known hardware which uses this (so it is not tested yet).

Clear the xMII isolation bit when set at initialization time if it was
previously set by the bootloader. Not doing so could lead to no traffic
(neither RX nor TX) on a port with this bit set.

While here, also add the GSWIP_MII_CFG_RESET bit. We don't need to
manage it because this bit is self-clearning when set. We still add it
here to get a better overview of the GSWIP_MII_CFG register.

3e9005be87 net: dsa: lantiq_gswip: Don't use PHY auto polling
PHY auto polling on the GSWIP hardware can be used so link changes
(speed, link up/down, etc.) can be detected automatically. Internally
GSWIP reads the PHY's registers for this functionality. Based on this
automatic detection GSWIP can also automatically re-configure it's port
settings. Unfortunately this auto polling (and configuration) mechanism
seems to cause various issues observed by different people on different
devices:
- FritzBox 7360v2: the two Gbit/s ports (connected to the two internal
  PHY11G instances) are working fine but the two Fast Ethernet ports
  (using an AR8030 RMII PHY) are completely dead (neither RX nor TX are
  received). It turns out that the AR8030 PHY sets the BMSR_ESTATEN bit
  as well as the ESTATUS_1000_TFULL and ESTATUS_1000_XFULL bits. This
  makes the PHY auto polling state machine (rightfully?) think that the
  established link speed (when the other side is Gbit/s capable) is
  1Gbit/s.
- None of the Ethernet ports on the Zyxel P-2812HNU-F1 (two are
  connected to the internal PHY11G GPHYs while the other three are
  external RGMII PHYs) are working. Neither RX nor TX traffic was
  observed. It is not clear which part of the PHY auto polling state-
  machine caused this.
- FritzBox 7412 (only one LAN port which is connected to one of the
  internal GPHYs running in PHY22F / Fast Ethernet mode) was seeing
  random disconnects (link down events could be seen). Sometimes all
  traffic would stop after such disconnect. It is not clear which part
  of the PHY auto polling state-machine cauased this.
- TP-Link TD-W9980 (two ports are connected to the internal GPHYs
  running in PHY11G / Gbit/s mode, the other two are external RGMII
  PHYs) was affected by similar issues as the FritzBox 7412 just without
  the "link down" events

Switch to software based configuration instead of PHY auto polling (and
letting the GSWIP hardware configure the ports automatically) for the
following link parameters:
- link up/down
- link speed
- full/half duplex
- flow control (RX / TX pause)

After a big round of manual testing by various people (who helped test
this on OpenWrt) it turns out that this fixes all reported issues.

Additionally it can be considered more future proof because any
"quirk" which is implemented for a PHY on the driver side can now be
used with the GSWIP hardware as well because Linux is in control of the
link parameters.

As a nice side-effect this also solves a problem where fixed-links were
not supported previously because we were relying on the PHY auto polling
mechanism, which cannot work for fixed-links as there's no PHY from
where it can read the registers. Configuring the link settings on the
GSWIP ports means that we now use the settings from device-tree also for
ports with fixed-links.

48d499bd89 of: unittest: overlay: ensure proper alignment of copied FDT
The Devicetree standard specifies an 8 byte alignment of the FDT.
Code in libfdt expects this alignment for an FDT image in memory.
kmemdup() returns 4 byte alignment on openrisc.  Replace kmemdup()
with kmalloc(), align pointer, memcpy() to get proper alignment.

The 4 byte alignment exposed a related bug which triggered a crash
on openrisc with:
commit 79edff1206 ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9")

Null pointer dereference happens on master->slaves dereference in
teql_destroy() as master is null-pointer.

When qdisc_create() calls teql_qdisc_init() it imediately fails after
check "if (m->dev == dev)" because both devices are teql0, and it does
not set qdisc_priv(sch)->m leaving it zero on error path, then
qdisc_create() imediately calls teql_destroy() which does not expect
zero master pointer and we get OOPS.
