This implements SOCK_DESTROY for TCP sockets. It causes all
blocking calls on the socket to fail fast with ECONNABORTED and
causes a protocol close of the socket. It informs the other end
of the connection by sending a RST, i.e., initiating a TCP ABORT
as per RFC 793. ECONNABORTED was chosen for consistency with
FreeBSD.

This passes the SOCK_DESTROY operation to the underlying protocol
diag handler, or returns -EOPNOTSUPP if that handler does not
define a destroy operation.
Most of this patch is just renaming functions. This is not
strictly necessary, but it would be fairly counterintuitive to
have the code to destroy inet sockets be in a function whose name
starts with inet_diag_get.

This patch implements an ILA tanslation table. This table can be
configured with identifier to locator mappings, and can be be queried
to resolve a mapping. Queries can be parameterized based on interface,
direction (incoming or outoing), and matching locator. The table is
implemented using rhashtable and is configured via netlink (through
"ip ila .." in iproute).
The table may be used as alternative means to do do ILA tanslations
other than the lw tunnels

Add skb_csum_offload_chk driver helper function to determine if a
device with limited checksum offload capabilities is able to offload the
checksum for a given packet.
This patch includes:
- The skb_csum_offload_chk function. Returns true if checksum is
offloadable, else false. Optionally, in the case that the checksum
is not offloable, the function can call skb_checksum_help to resolve
the checksum. skb_csum_offload_chk also returns whether the checksum
refers to an encapsulated checksum.
- Definition of skb_csum_offl_spec structure that caller uses to
indicate rules about what it can offload (e.g. IPv4/v6, TCP/UDP only,
whether encapsulated checksums can be offloaded, whether checksum with
IPv6 extension headers can be offloaded).
- Ancilary functions called skb_csum_offload_chk_help,
skb_csum_off_chk_help_cmn, skb_csum_off_chk_help_cmn_v4_only.

In tcp_send_sendpage and tcp_sendmsg we check the route capabilities to
determine if checksum offload can be performed. This check currently
does not take the IP protocol into account for devices that advertise
only one of NETIF_F_IPV6_CSUM or NETIF_F_IP_CSUM. This patch adds a
function to check capabilities for checksum offload with a socket
called sk_check_csum_caps. This function checks for specific IPv4 or
IPv6 offload support based on the family of the socket.

These netif flags are unnecessary convolutions. It is more
straightforward to just use NETIF_F_HW_CSUM, NETIF_F_IP_CSUM,

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.
This patch:
- Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
NETIF_F_ALL_CSUM is being used as a mask).
- Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

The SCTP checksum is really a CRC and is very different from the
standards 1's complement checksum that serves as the checksum
for IP protocols. This offload interface is also very different.
Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these
differences. The term CSUM should be reserved in the stack to refer
to the standard 1's complement IP checksum.

switchdev drivers need to know the netdev on which the switchdev op was
invoked. For example, the STP state of a VLAN interface configured on top
of a port can change while being member in a bridge. In this case, the
underlying driver should only change the STP state of that particular
VLAN and not of all the VLANs configured on the port.
However, current switchdev infrastructure only passes the port netdev down
to the driver. Solve that by passing the original device down to the
driver as part of the required switchdev object / attribute.
This doesn't entail any change in current switchdev drivers. It simply
enables those supporting stacked devices to know the originating device
and act accordingly.

We need to be able to propagate static FDB entries and certain bridge
port attributes (e.g. learning, flooding) down to the port netdev
driver when bridge port is a VLAN interface.
Achieve that by setting ndo_bridge* and ndo_fdb* in vlan_netdev_ops to
the corresponding switchdev_port* functions. This is consistent with
team and bond devices.

When the linear buffer of the received sk_buff is shorter than
the header, use skb_linearize(). sk_buffs with short linear buffer
happen on the sending side under high traffic, and some kernel
configurations, when allocated buffer starts just before page
boundary, and IUCV transport has to send it as two separate QDIO
buffer elements, with fist element shorter than the header.

This patch removes ARPHRD_IEEE802154 from addrconf handling. In the
earlier days of 802.15.4 6LoWPAN, the interface type was ARPHRD_IEEE802154
which introduced several issues, because 802.15.4 interfaces used the
same type.
Since commit 965e613d299c ("ieee802154: 6lowpan: fix ARPHRD to
ARPHRD_6LOWPAN") we use ARPHRD_6LOWPAN for 6LoWPAN interfaces. This
patch will remove ARPHRD_IEEE802154 which is currently deadcode, because
ARPHRD_IEEE802154 doesn't reach the minimum 1280 MTU of IPv6.
Also we use 6LoWPAN EUI64 specific defines instead using link-layer
constanst from 802.15.4 link-layer header.

A Linux PC is connected with another device over Bluetooth PAN using a
BNEP interface.
Whenever a packet is tried to be sent over the BNEP interface, the
function "bnep_net_xmit()" in "net/bluetooth/bnep/netdev.c" is called.
This function calls "bnep_net_mc_filter()", which checks (if the
destination address is multicast) if the address is set in a certain
multicast filter (&s->mc_filter). If it is not, then it is not sent out.
This filter is only changed in two other functions, found in
net/bluetooth/bnep/core.c": in "bnep_ctrl_set_mc_filter()", which is
only called if a message of type "BNEP_FILTER_MULTI_ADDR_SET" is
received. Otherwise, it is set in "bnep_add_connection()", where it is
set to a default value which only adds the broadcast address to the
filter:
set_bit(bnep_mc_hash(dev->broadcast), (ulong *) &s->mc_filter);
To sum up, if the BNEP interface does not receive any message of type
"BNEP_FILTER_MULTI_ADDR_SET", it will not send out any messages with
multicast destination addresses except for broadcast.
However, in the BNEP specification (page 27 in
http://grouper.ieee.org/groups/802/15/Bluetooth/BNEP.pdf), it is said
that per default, all multicast addresses should not be filtered, i.e.
the BNEP interface should be able to send packets with any multicast
destination address.
It seems that the default case is wrong: the multicast filter should not
block almost all multicast addresses, but should not filter out any.
This leads to the problem that e.g. Neighbor Solicitation messages sent
with Bluetooth PAN over the BNEP interface to a multicast destination
address other than broadcast are blocked and not sent out.
Therefore, in the default case, we set the mc_filter to ~0LL to not
filter out any multicast addresses.

This patch reverts 6001d52 ("mac802154: tx: don't allow if down while
sync tx"). This has side effects with stop callback which flush the
transmit workqueue. The stop callback will wait until the workqueue is
flushed and holding the rtnl lock. That means it can happen that the stop
callback waits forever because it try to lock the rtnl mutex which is
already hold by stop callback.

When we're doing background scanning and connection attempts it's
possible we timeout trying to connect and go back to scanning again.
The timeout triggers a HCI_LE_Create_Connection_Cancel which will
trigger a Connection Complete with "Unknown Connection Identifier"
error status. Since we go back to scanning this isn't really a failure
and shouldn't be presented as such to user space through mgmt.
The exception to this is if the connection attempt was due to an
explicit request on an L2CAP socket (indicated by
params->explicit_connect being true). Since the socket will get an
error it's consistent to also notify the failure on mgmt in this case.

All LE connections are now triggered through a preceding passive scan
and waiting for a connectable advertising report. This means we've got
the best possible guarantee that the device is within range and should
be able to request the controller to perform continuous scanning. This
way we minimize the risk that we miss out on any advertising packets.

The logic in powered_update_hci() to initialize the advertising data &
state is a bit more complicated than it needs to be. It was previously
not doing anything if HCI_LE_ENABLED wasn't set, but this was not
obvious by quickly looking at the code. Now the conditions for the
various actions are more explicit. Another simplification is due to
the fact that __hci_req_schedule_adv_instance() takes care of setting
hdev->cur_adv_instance so there's no need to set it before calling the

This flag just tells us whether hdev->adv_instances is empty or not.
We can equally well use the list_empty() function to get this
information.

The request to update HCI during power on is always coming either from
hdev->req_workqueue or through an ioctl, so it's safe to use
hci_req_sync for it. This way we also eliminate potential races with
incoming mgmt commands or other actions while powering on.
Part of this refactoring is the splitting of mgmt_powered() into
mgmt_power_on() and __mgmt_power_off() functions. The main reason is
the different requirements as far as hdev locking is concerned, as
highlighted with the __ prefix of the power off API.
Since the power on in the case of clearing the AUTO_OFF flag cannot be
done synchronously in the set_powered mgmt handler, the hci_power_on
work callback is extended to cover this (which also simplifies the
set_powered helper a lot).

We'll soon need this both in hci_request.c and mgmt.c so move it to
hci_request.c as a generic helper.

Since the other discoverable changes are behind req_workqueue now it
only makes sense to move the discoverable timeout there as well.

The discoverable mode is intrinsically linked with the connectable
mode e.g. through sharing the same HCI command (Write Scan Enable) for
BR/EDR. It makes therefore sense to move it to hci_request.c and run
the changes through the same hdev->req_workqueue.

The Class of Device needs to be changed e.g. for limited discoverable

This way the connectable changes are synchronized against each other,
which helps avoid potential races. The connectable mode is also linked
together with LE advertising which makes is more convenient to have it
behind the same workqueue.

This paves the way for eventually performing advertising changes
through the hdev->req_workqueue. Some new APIs need to be exposed from
mgmt.c to hci_request.c and vice-versa, but many of them will go away
once hdev->req_workqueue gets used.

Since Add/Remove Device perform the page scan updates independently
from the HCI command completion we've introduced a potential race when
multiple mgmt commands are queued. Doing the page scan updates through
the req_workqueue ensures that the state changes are performed in a
race-free manner.
At the same time, to make the request helper more widely usable,
extend it to also cover Inquiry Scan changes since those are behind
the same HCI command. This is also reflected in the new name of the
API as well as the work struct name.
