tcp: plug dst leak in tcp_v6_conn_request()
The code in tcp_v6_conn_request() was implicitly assuming that
tcp_v6_send_synack() would take care of dst_release(), much as
tcp_v4_send_synack() already does. This resulted in
tcp_v6_conn_request() leaking a dst if sysctl_tw_recycle is enabled.
This commit restructures tcp_v6_send_synack() so that it accepts a dst
pointer and takes care of releasing the dst that is passed in, to plug
the leak and avoid future surprises by bringing the IPv6 behavior in

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:

The routing cache precomputes this value, but we want to remove that

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.

ipv4: tcp: dont cache unconfirmed intput dst
DDOS synflood attacks hit badly IP route cache.
On typical machines, this cache is allowed to hold up to 8 Millions dst
entries, 256 bytes for each, for a total of 2GB of memory.
rt_garbage_collect() triggers and tries to cleanup things.
Eventually route cache is disabled but machine is under fire and might
OOM and crash.
This patch exploits the new TCP early demux, to set a nocache
boolean in case incoming TCP frame is for a not yet ESTABLISHED or
TIMEWAIT socket.
This 'nocache' boolean is then used in case dst entry is not found in
route cache, to create an unhashed dst entry (DST_NOCACHE)
SYN-cookie-ACK sent use a similar mechanism (ipv4: tcp: dont cache
output dst for syncookies), so after this patch, a machine is able to
absorb a DDOS synflood attack without polluting its IP route cache.

receiver is required to return it to the sender. mac80211
