ipv6_tunnel: Allow receiving packets on the fallback tunnel if they pass sanity checks

At Facebook, we do Layer-3 DSR via IP-in-IP tunneling. Our load balancers wrap
an extra IP header on incoming packets so they can be routed to the backend.
In the v4 tunnel driver, when these packets fall on the default tunl0 device,
the behavior is to decapsulate them and drop them back on the stack. So our
setup is that tunl0 has the VIP and eth0 has (obviously) the backend's real
address.

In IPv6 we do the same thing, but the v6 tunnel driver didn't have this same
behavior - if you didn't have an explicit tunnel setup, it would drop the
packet.

This patch brings that v4 feature to the v6 driver.

The same IPv6 address checks are performed as with any normal tunnel,
but as the fallback tunnel endpoint addresses are unspecified, the checks
must be performed on a per-packet basis, rather than at tunnel
configuration time.

net: qmi_wwan: fix Oops while disconnecting

usbnet_disconnect() will set intfdata to NULL before calling
the minidriver unbind function.  The cdc_wdm subdriver cannot
know that it is disconnecting until the qmi_wwan unbind
function has called its disconnect function.  This means that
we must be able to support the cdc_wdm subdriver operating
normally while usbnet_disconnect() is running, and in
particular that intfdata may be NULL.

The only place this matters is in qmi_wwan_cdc_wdm_manage_power
which is called from cdc_wdm.  Simply testing for NULL
intfdata there is sufficient to allow it to continue working
at all times.

Fixes this Oops where a cdc-wdm device was closed while the
USB device was disconnecting, causing wdm_release to call
qmi_wwan_cdc_wdm_manage_power after intfdata was set to
NULL by usbnet_disconnect:

If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we
indicate this so that get_phy_device() can properly probe the device.

If get_phy_device() fails, it was probably due to failing the probe of
the PHY identifier registers.  Since we have the device tree telling
us the PHY exists, go ahead and add it anyhow with a phy_id of zero.
There may be a driver match based on the "compatible" property.

12 years agonetdev/phy: Handle IEEE802.3 clause 45 Ethernet PHYs

netdev/phy: Handle IEEE802.3 clause 45 Ethernet PHYs

The IEEE802.3 clause 45 MDIO bus protocol allows for directly
addressing PHY registers using a 21 bit address, and is used by many
10G Ethernet PHYS.  Already existing is the ability of MDIO bus
drivers to use clause 45, with the MII_ADDR_C45 flag.  Here we add
struct phy_c45_device_ids to hold the device identifier registers
present in clause 45. struct phy_device gets a couple of new fields:
c45_ids to hold the identifiers and is_c45 to signal that it is clause
45.

get_phy_device() gets a new parameter is_c45 to indicate that the PHY
device should use the clause 45 protocol, and its callers are adjusted
to pass false.  The follow-on patch to of_mdio.c will pass true where
appropriate.

EXPORT phy_device_create() so that the follow-on patch to of_mdio.c
can use it to create phy devices for PHYs, that have non-standard
device identifier registers, based on the device tree bindings.

cnic: Fix occasional NULL pointer dereference during reboot.

We register with bnx2x before we allocate ctx_tbl structure, so it is
possible for bnx2x to call cnic_ctl before the structure is allocated.
This can sometimes cause NULL pointer dereference of cp->ctx_tbl.  We
fix this by adding simple checking for valid state before proceeding.
The cnic_ctl call is RCU protected so we don't have to deal with race
conditions.

Because of the additional checking, we need to finish the shutdown
before clearing the CNIC_UP flag.
