With some mss values, it is possible tcp_xmit_size_goal() puts
one segment more in TSO packet than tcp_tso_autosize().
We send then one TSO packet followed by one single MSS.
It is not a serious bug, but we can do slightly better, especially
for drivers using netif_set_gso_max_size() to lower gso_max_size.
Using same formula avoids these corner cases and makes
tcp_xmit_size_goal() a bit faster.

Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:
1) Don't truncate ethernet protocol type to u8 in nft_compat, from
Arturo Borrero.
2) Fix several problems in the addition/deletion of elements in nf_tables.
3) Fix module refcount leak in ip_vs_sync, from Julian Anastasov.
4) Fix a race condition in the abort path in the nf_tables transaction
infrastructure. Basically aborted rules can show up as active rules
until changes are unrolled, oneliner from Patrick McHardy.
5) Check for overflows in the data area of the rule, also from Patrick.
6) Fix off-by-one in the per-rule user data size field. This introduces
a new nft_userdata structure that is placed at the beginning of the
user data area that contains the length to save some bits from the
rule and we only need one bit to indicate its presence, from Patrick.
7) Fix rule replacement error path, the replaced rule is deleted on
error instead of leaving it in place. This has been fixed by relying
on the abort path to undo the incomplete replacement.

IEEE 802.11 Proxy ARP") with optional set of rules that are needed to
meet the IEEE 802.11 and Hotspot 2.0 requirements for ProxyARP. The
previously added BR_PROXYARP behavior is left as-is and a new
BR_PROXYARP_WIFI alternative is added so that this behavior can be
configured from user space when required.
In addition, this enables proxyarp functionality for unicast ARP
requests for both BR_PROXYARP and BR_PROXYARP_WIFI since it is possible
to use unicast as well as broadcast for these frames.
The key differences in functionality:
BR_PROXYARP:
- uses the flag on the bridge port on which the request frame was
received to determine whether to reply
- block bridge port flooding completely on ports that enable proxy ARP
BR_PROXYARP_WIFI:
- uses the flag on the bridge port to which the target device of the
request belongs
- block bridge port flooding selectively based on whether the proxyarp
functionality replied

This patch fixes service discovery behaviour, when provided uuid filter
is empty and HCI_QUIRK_STRICT_DUPLICATE_FILTER is set. Before this
patch, empty uuid filter was unable to trigger scan restart, and that
caused inconsistent behaviour in applications.
Example: two DBus clients call BlueZ, one to find all devices with
service abcd, second to find all devices with rssi smaller than -90.
Sum of those filters, that is passed to mgmt_service_scan is empty
filter, with no rssi or uuids set.
That caused kernel not to restart scan when quirk was set.
That was inconsistent with what happen when there's only one of those
two filters set (scan is restarted and reports devices).
To fix that, new variable hdev->discovery.result_filtering was
introduced. It can indicate that filtered scan is running, no matter
what uuid or rssi filter is set.

1. For an IPv4 ping socket, ping_check_bind_addr does not check
the family of the socket address that's passed in. Instead,
make it behave like inet_bind, which enforces either that the
address family is AF_INET, or that the family is AF_UNSPEC and
the address is 0.0.0.0.
2. For an IPv6 ping socket, ping_check_bind_addr returns EINVAL
if the socket family is not AF_INET6. Return EAFNOSUPPORT
instead, for consistency with inet6_bind.
3. Make ping_v4_sendmsg and ping_v6_sendmsg return EAFNOSUPPORT
instead of EINVAL if an incorrect socket address structure is
passed in.
4. Make IPv6 ping sockets be IPv6-only. The code does not support

the protocol numbers for ICMP and ICMPv6 are different. This
makes connect(::ffff:192.0.2.1) fail with EAFNOSUPPORT instead
of making the socket unusable.
Among other things, this fixes an oops that can be triggered by:

.sin6_family = AF_INET6,
.sin6_addr = in6addr_any,

A race condition exists in the rule transaction code for rules that
get added and removed within the same transaction.
The new rule starts out as inactive in the current and active in the
next generation and is inserted into the ruleset. When it is deleted,
it is additionally set to inactive in the next generation as well.
On commit the next generation is begun, then the actions are finalized.
For the new rule this would mean clearing out the inactive bit for
the previously current, now next generation.
However nft_rule_clear() clears out the bits for *both* generations,
activating the rule in the current generation, where it should be
deactivated due to being deleted. The rule will thus be active until
the deletion is finalized, removing the rule from the ruleset.
Similarly, when aborting a transaction for the same case, the undo
of insertion will remove it from the RCU protected rule list, the
deletion will clear out all bits. However until the next RCU
synchronization after all operations have been undone, the rule is
active on CPUs which can still see the rule on the list.
Generally, there may never be any modifications of the current
generations' inactive bit since this defeats the entire purpose of
atomicity. Change nft_rule_clear() to only touch the next generations
bit to fix this.

This change adds two new netlink routing attributes:
RTA_VIA and RTA_NEWDST.
RTA_VIA specifies the specifies the next machine to send a packet to
like RTA_GATEWAY. RTA_VIA differs from RTA_GATEWAY in that it
includes the address family of the address of the next machine to send
a packet to. Currently the MPLS code supports addresses in AF_INET,
AF_INET6 and AF_PACKET. For AF_INET and AF_INET6 the destination mac
address is acquired from the neighbour table. For AF_PACKET the
destination mac_address is specified in the netlink configuration.
I think raw destination mac address support with the family AF_PACKET
will prove useful. There is MPLS-TP which is defined to operate
on machines that do not support internet packets of any flavor. Further
seem to be corner cases where it can be useful. At this point
I don't care much either way.
RTA_NEWDST specifies the destination address to forward the packet
with. MPLS typically changes it's destination address at every hop.
For a swap operation RTA_NEWDST is specified with a length of one label.
For a push operation RTA_NEWDST is specified with two or more labels.
For a pop operation RTA_NEWDST is not specified or equivalently an emtpy
RTAN_NEWDST is specified.
Those new netlink attributes are used to implement handling of rt-netlink
RTM_NEWROUTE, RTM_DELROUTE, and RTM_GETROUTE messages, to maintain the
MPLS label table.
rtm_to_route_config parses a netlink RTM_NEWROUTE or RTM_DELROUTE message,
verify no unhandled attributes or unhandled values are present and sets
up the data structures for mpls_route_add and mpls_route_del.
I did my best to match up with the existing conventions with the caveats
that MPLS addresses are all destination-specific-addresses, and so
don't properly have a scope.

Reading and writing addresses in network byte order in netlink is
traditional and I see no reason to change that. MPLS is interesting
as effectively it has variabely length addresses (the MPLS label
stack). To represent these variable length addresses in netlink
I use a valid MPLS label stack (complete with stop bit).
This achieves two things: a well defined existing format is used,
and the data can be interpreted without looking at it's length.
Not needed to look at the length to decode the variable length
network representation allows existing userspace functions
such as inet_ntop to be used without needed to change their
prototype.

mpls_route_add and mpls_route_del implement the basic logic for adding
and removing Next Hop Label Forwarding Entries from the MPLS input
label map. The addition and subtraction is done in a way that is
consistent with how the existing routing table in Linux are
maintained. Thus all of the work to deal with NLM_F_APPEND,
NLM_F_EXCL, NLM_F_REPLACE, and NLM_F_CREATE.
Cases that are not clearly defined such as changing the interpretation
of the mpls reserved labels is not allowed.
Because it seems like the right thing to do adding an MPLS route without
specifying an input label and allowing the kernel to pick a free label
table entry is supported. The implementation is currently less than optimal
but that can be changed.
As I don't have anything else to test with only ethernet and the loopback
device are the only two device types currently supported for forwarding
MPLS over.

This sysctl gives two benefits. By defaulting the table size to 0
mpls even when compiled in and enabled defaults to not forwarding
any packets. This prevents unpleasant surprises for users.
The other benefit is that as mpls labels are allocated locally a dense
table a small dense label table may be used which saves memory and
is extremely simple and efficient to implement.
This sysctl allows userspace to choose the restrictions on the label
table size userspace applications need to cope with.

This change adds a new Kconfig option MPLS_ROUTING.
The core of this change is the code to look at an mpls packet received
from another machine. Look that packet up in a routing table and
forward the packet on.
Support of MPLS over ATM is not considered or attempted here. This
implemntation follows RFC3032 and implements the MPLS shim header that
can pass over essentially any network.
What RFC3021 refers to as the as the Incoming Label Map (ILM) I call
net->mpls.platform_label[]. What RFC3031 refers to as the Next Label
Hop Forwarding Entry (NHLFE) I call mpls_route. Though calling it the
label fordwarding information base (lfib) might also be valid.
Further the implemntation forwards packets as described in RFC3032.
There is no need and given the original motivation for MPLS a strong
discincentive to have a flexible label forwarding path. In essence
the logic is the topmost label is read, looked up, removed, and
replaced by 0 or more new lables and the sent out the specified
interface to it's next hop.
Quite a few optional features are not implemented here. Among them
are generation of ICMP errors when the TTL is exceeded or the packet
is larger than the next hop MTU (those conditions are detected and the
packets are dropped instead of generating an icmp error). The traffic
class field is always set to 0. The implementation focuses on IP over
MPLS and does not handle egress of other kinds of protocols.
Instead of implementing coordination with the neighbour table and
sorting out how to input next hops in a different address family (for
which there is value). I was lazy and implemented a next hop mac
address instead. The code is simpler and there are flavor of MPLS
such as MPLS-TP where neither an IPv4 nor an IPv6 next hop is
appropriate so a next hop by mac address would need to be implemented
at some point.
Two new definitions AF_MPLS and PF_MPLS are exposed to userspace.
Decoding the mpls header must be done by first byeswapping a 32bit bit
endian word into the local cpu endian and then bit shifting to extract
the pieces. There is no C bit-field that can represent a wire format
mpls header on a little endian machine as the low bits of the 20bit
label wind up in the wrong half of third byte. Therefore internally
everything is deal with in cpu native byte order except when writing
to and reading from a packet.
For management simplicity if a label is configured to forward out
an interface that is down the packet is dropped early. Similarly
if an network interface is removed rt_dev is updated to NULL
(so no reference is preserved) and any packets for that label
are dropped. Keeping the label entries in the kernel allows
the kernel label table to function as the definitive source
of which labels are allocated and which are not.

The kind of next hop we have is indicated by the neighbour table
pointer. A neighbour table pointer of NULL is a link layer address.
A non-NULL neighbour table pointer indicates which neighbour table and
thus which address family the next hop address is in that we need to

tasks, wrt testing the MSG_CMSG_COMPAT bit. Just ignore it if the
user happened to set it in a native binary as that was always the
behavior we had. From Catalin Marinas.
14) Check genlmsg_unicast() return valud in hwsim netlink tx frame
handling, from Bob Copeland.
15) Fix stale ->radar_required setting in mac80211 that can prevent
starting new scans, from Eliad Peller.
16) Fix memory leak in nl80211 monitor, from Johannes Berg.
17) Fix race in TX index handling in xen-netback, from David Vrabel.
18) Don't enable interrupts in amx-xgbe driver until all software et al.
state is ready for the interrupt handler to run. From Thomas
Lendacky.
19) Add missing netlink_ns_capable() checks to rtnl_newlink(), from Eric
W Biederman.
20) The amount of header space needed in macvtap was not calculated
properly, fix it otherwise we splat past the beginning of the
packet. From Eric Dumazet.
21) Fix bcmgenet TCP TX perf regression, from Jaedon Shin.
22) Don't raw initialize or mod timers, use setup_timer() and
mod_timer() instead. From Vaishali Thakkar.
23) Fix software maintained statistics in bcmgenet and systemport
drivers, from Florian Fainelli.
24) DMA descriptor updates in sh_eth need proper memory barriers, from
Ben Hutchings.
25) Don't do UDP Fragmentation Offload on RAW sockets, from Michal
Kubecek.
