net: Improve code coverage of syzkaller

This patch series is intended to improve code coverage of syzkaller on
the early receive path, specifically including flow dissector, GRO,
and GRO with frags parts of the networking stack. Syzkaller exercises
the stack through the TUN driver and this is therefore where changes
reside. Current coverage through netif_receive_skb() is limited as it
does not touch on any of the aforementioned code paths. Furthermore,
for full coverage, it is necessary to have more flexibility over the
linear and non-linear data of the skbs.

The following patches address this by providing the user(syzkaller)
with the ability to send via napi_gro_receive() and napi_gro_frags().
Additionally, syzkaller can specify how many fragments there are and
how much data per fragment there is. This is done by exploiting the
convenient structure of iovecs. Finally, this patch series adds
support for exercising the flow dissector during fuzzing.

The code path including napi_gro_receive() can be enabled via the
IFF_NAPI flag.  The remainder of the changes in this patch series give
the user significantly more control over packets entering the kernel.
To avoid potential security vulnerabilities, hide the ability to send
custom skbs and the flow dissector code paths behind a
capable(CAP_NET_ADMIN) check to require special user privileges.

Changes since v2 based on feedback from Willem de Bruijn and Mahesh
Bandewar:

Patch 1/ No changes.
Patch 2/ Check if the preconditions for IFF_NAPI_FRAGS (IFF_NAPI and
	 IFF_TAP) are met before opening/attaching rather than after.
	 If they are not, change the behavior from discarding the
	 flag to rejecting the command with EINVAL.
====================

Add a TUN/TAP receive mode that exercises the napi_gro_frags()
interface. This mode is available only in TAP mode, as the interface
expects packets with Ethernet headers.

Furthermore, packets follow the layout of the iovec_iter that was
received. The first iovec is the linear data, and every one after the
first is a fragment. If there are more fragments than the max number,
drop the packet. Additionally, invoke eth_get_headlen() to exercise flow
dissector code and to verify that the header resides in the linear data.

The napi_gro_frags() mode requires setting the IFF_NAPI_FRAGS option.
This is imposed because this mode is intended for testing via tools like
syzkaller and packetdrill, and the increased flexibility it provides can
introduce security vulnerabilities. This flag is accepted only if the
device is in TAP mode and has the IFF_NAPI flag set as well. This is
done because both of these are explicit requirements for correct
operation in this mode.

Changes TUN driver to use napi_gro_receive() upon receiving packets
rather than netif_rx_ni(). Adds flag IFF_NAPI that enables these
changes and operation is not affected if the flag is disabled.  SKBs
are constructed upon packet arrival and are queued to be processed
later.

The new path was evaluated with a benchmark with the following setup:
Open two tap devices and a receiver thread that reads in a loop for
each device. Start one sender thread and pin all threads to different
CPUs. Send 1M minimum UDP packets to each device and measure sending
time for each of the sending methods:
	napi_gro_receive():	4.90s
	netif_rx_ni():		4.90s
	netif_receive_skb():	7.20s

These two drivers (dummy and ifb) call ether_setup(), after commit
61e84623 ("net: centralize net_device min/max MTU checking"), the
range of mtu is [min_mtu, max_mtu], which is [68, 1500] by default.

These two devices should not have limits on MTU. This patch set their
min_mtu/max_mtu to 0. So that dev_set_mtu() will not check the mtu range,
and can be set with any value.

cxgb4: add support to offload tc flower

This series of patches add support to offload tc flower onto Chelsio
NICs.

Patch 1 adds basic skeleton to prepare for offloading tc flower flows.

Patch 2 adds support to add/remove flows for offload.  Flows can have
accompanying masks.  Following match and action are currently supported
for offload:
Match:  ether-protocol, IPv4/IPv6 addresses, L4 ports (TCP/UDP)
Action: drop, redirect to another port on the device.

Patch 3 adds support to offload tc-flower flows having
vlan actions: pop, push, and modify.

Patch 4 adds support to fetch stats for the offloaded tc flower flows
from hardware.

Support for offloading more match and action types are to be followed
in subsequent series.

v2:
- Setting ftid to -1 not required after bitmap_find_free_region
  in cxgb4_get_free_ftid.
- Direct return can be used as jumping to error path is not needed
  if flower entry allocation failed in cxgb4_tc_flower_replace.
  Same applies if flower entry not found in cxgb4_tc_flower_destroy.
- Also, removed an extra return from cxgb4_tc_flower_destroy.
- Avoid wrapping line for netdev_err message. Also, use
  consistent error message string.

net: fix reuseaddr regression

I introduced a regression when reworking the fastreuse port stuff that allows
bind conflicts to occur once a reuseaddr successfully opens on an existing tb.
The root cause is I reversed an if statement which caused us to set the tb as if
there were no owners on the socket if there were, which obviously is not
correct.

This is obviously bad as all of the reuseport/reuse logic was reversed,
which caused weird problems like allowing an ipv4 bind conflict if we
opened an ipv4 only socket on a port followed by an ipv6 only socket on
the same port.
