In commit cd7d8498c9a5 ("tcp: change tcp_skb_pcount() location") we stored
gso_segs in a temporary cache hot location.
This patch does the same for gso_size.
This allows to save 2 cache line misses in tcp xmit path for
the last packet that is considered but not sent because of
various conditions (cwnd, tso defer, receiver window, TSQ...)

Our goal is to touch skb_shinfo(skb) only when absolutely needed,
to avoid two cache line misses in TCP output path for last skb
that is considered but not sent because of various conditions
(cwnd, tso defer, receiver window, TSQ...)
A packet is GSO only when skb_shinfo(skb)->gso_size is not zero.
We can set skb_shinfo(skb)->gso_type to sk->sk_gso_type even for
non GSO packets.

tcp_gso_segment() and tcp_gro_receive() are not strictly
part of TCP stack. They should not assume tcp_skb_mss(skb)
is in fact skb_shinfo(skb)->gso_size.
This will allow us to change tcp_skb_mss() in following patches.

Fix a BUG_ON() where CONFIG_NET_SWITCHDEV is set but the driver for a
bridged port does not support switchdev_port_attr_set op. Don't BUG_ON()
if -EOPNOTSUPP is returned.
Also change BUG_ON() to netdev_err since this is a normal error path and
does not warrant the use of BUG_ON(), which is reserved for unrecoverable

Some NFC controller supports UART as host interface.
As with SPI, a lot of code can be shared between vendor
drivers. This patch add the generic support of UART and
provides some extension API for vendor specific needs.
This code is strongly inspired by the Bluetooth HCI ldisc

themselves to this layer via nci_uart_register.

CAIA Delay-Gradient (CDG) is a TCP congestion control that modifies
the TCP sender in order to [1]:
o Use the delay gradient as a congestion signal.
o Back off with an average probability that is independent of the RTT.
o Coexist with flows that use loss-based congestion control, i.e.,
flows that are unresponsive to the delay signal.
o Tolerate packet loss unrelated to congestion. (Disabled by default.)
Its FreeBSD implementation was presented for the ICCRG in July 2012;
slides are available at http://www.ietf.org/proceedings/84/iccrg.html
Running the experiment scenarios in [1] suggests that our implementation
achieves more goodput compared with FreeBSD 10.0 senders, although it also
causes more queueing delay for a given backoff factor.
The loss tolerance heuristic is disabled by default due to safety concerns
for its use in the Internet [2, p. 45-46].
We use a variant of the Hybrid Slow start algorithm in tcp_cubic to reduce
the probability of slow start overshoot.

If CONFIG_NET_SWITCHDEV is enabled, but port driver does not implement
support for IPv4 FIB add/del ops, don't fail route add/del offload
operations. Route adds will not be marked as OFFLOAD. Routes will be
installed in the kernel FIB, as usual.
This was report/fixed by Florian when testing DSA driver with net-next on
devices with L2 offload support but no L3 offload support. What he reported
was an initial route installed from DHCP client would fail (route not
installed to kernel FIB). This was triggering the setting of
ipv4.fib_offload_disabled, which would disable route offloading after the
first failure. So subsequent attempts to install the route would succeed.
There is follow-on work/discussion to address the handling of route install
failures, but for now, let's differentiate between no support and failed
support.

Also, playing with small dctcp_shift_g (like 1), can expose

Since the addition of sysfs multicast router support if one set
multicast_router to "2" more than once, then the port would be added to
the hlist every time and could end up linking to itself and thus causing an
endless loop for rlist walkers.
So to reproduce just do:
echo 2 > multicast_router; echo 2 > multicast_router;
in a bridge port and let some igmp traffic flow, for me it hangs up
in br_multicast_flood().
Fix this by adding a check in br_multicast_add_router() if the port is
already linked.
The reason this didn't happen before the addition of multicast_router
sysfs entries is because there's a !hlist_unhashed check that prevents
it.

If the TIPC connection timer expires in a probing state, a
self abort message is supposed to be generated and delivered
to the local socket. This is currently broken, and the abort
message is actually sent out to the peer node with invalid
addressing information. This will cause the link to enter
a constant retransmission state and eventually reset.
We fix this by removing the self-abort message creation and
tear down connection immediately instead.

bridge fdb add 00:11:22:33:44:55 dev eth0 master
bridge fdb del 00:11:22:33:44:55 dev eth1 master

This introduces a number of helper functions/macros to set and to

This patch fixes a bug in hwmp_preq_frame_process where the wrong metric
can be used when forwarding a PREQ. This happens because the code uses
the same metric variable to record the value of the metric to the source
of the PREQ and the value of the metric to the target of the PREQ.
This comes into play when both reply and forward are set which happens
when IEEE80211_PREQ_PROACTIVE_PREP_FLAG is set and when MP_F_DO | MP_F_RF
is set. The original code had a special case to handle the first case
but not the second.
The patch uses distinct variables for the two metrics which makes the
code flow much clearer and removes the need to restore the original
value of metric when forwarding.

Until recently, mac80211 overwrote all the statistics it could
provide when getting called, but it now relies on the struct
having been zeroed by the caller. This was always the case in
nl80211, but wext used a static struct which could even cause
values from one device leak to another.
Using a static struct is OK (as even documented in a comment)
since the whole usage of this function and its return value is
always locked under RTNL. Not clearing the struct for calling
the driver has always been wrong though, since drivers were
free to only fill values they could report, so calling this
for one device and then for another would always have leaked
values from one to the other.
Fix this by initializing the structure in question before the
driver method call.

Channels in 2.4GHz band overlap, this means that if we
send a probe request on channel 1 and then move to channel
2, we will hear the probe response on channel 2. In this
case, the RSSI will be lower than if we had heard it on
the channel on which it was sent (1 in this case).
The scan result ignores those invalid values and the
station last signal should not be updated as well.
In case the scan determines the signal to be invalid turn on
the flag so the station last signal will not be updated with
the value and thus user space probing for NL80211_STA_INFO_SIGNAL
and NL80211_STA_INFO_SIGNAL_AVG will not get this invalid RSSI

The UID is an optional non-zero value which can be provided at routing job
creation time. When the UID is set the UID replaces the data modification
configuration as job identification attribute e.g. at job removal time.

The encryption key size for LTKs is supposed to be applied only at the
moment of encryption. When generating a Link Key (using LE SC) from
the LTK the full non-shortened value should be used. This patch
modifies the code to always keep the full value around and only apply
the key size when passing the value to HCI.

Vendor commands are passed from userspace through the
NFC_CMD_VENDOR netlink command, allowing driver and hardware
specific operations implementations like for example RF tuning
or production line calibration.
Drivers will associate a set of vendor commands to a vendor
id, which could typically be an OUI. The netlink kernel
implementation will try to match the received vendor id
and sub command attributes with the registered ones. When
such match is found, the driver defined sub command routine
is called.

Several of these goto exit; uses should be direct returns
as skb is not yet initialized by nci_hci_get_param().
Miscellanea:
o Use !memcmp instead of memcmp() == 0
o Remove unnecessary goto from if () {... goto exit;} else {...} exit:

Commit 70008aa50e92 ("skbuff: convert to skb_orphan_frags") replaced
open coded tests of SKBTX_DEV_ZEROCOPY and skb_copy_ubufs with calls
to helper function skb_orphan_frags. Apply that to the last remaining
open coded site.

UDP encapsulation is broken on IPv6. This is because the logic to resubmit
the nexthdr is inverted, checking for a ret value > 0 instead of < 0. Also,
the resubmit label is in the wrong position since we already get the
nexthdr value when performing decapsulation. In addition the skb pull is no
longer necessary either.
This changes the return value check to look for < 0, using it for the
nexthdr on the next iteration, and moves the resubmit label to the proper
location.
With these changes the v6 code now matches what we do in the v4 ip input
code wrt resubmitting when decapsulating.
