When the bottom qdisc decides to, for example, drop some packet,
it calls qdisc_tree_decrease_qlen() to update the queue length
for all its ancestors, we need to update the backlog too to
keep the stats on root qdisc accurate.

1GbE Intel Wired LAN Driver Updates 2016-02-24
This series contains updates to e1000e, igb and igbvf.
Raanan provides updates for e1000e, first increases the ULP timer since it
now takes longer for the ULP exit to complete on Skylake. Fixes the
configuration of the internal hardware PHY clock gating mechanism, which was
causing packet loss due to mis configuring. Fixed additional ULP
configuration settings which were not being properly cleared after cable
connect in V-Pro capable systems. Added support for more i219 devices.
Takuma Ueba provides a fix for I210 where IPv6 autoconf test sometimes
fails due to DAD NS for link-local is not transmitted. To avoid this
issue, we need to wait until 1000BASE-T status register "Remote receiver
status OK".
Todd provides a patch to override EEPROM WoL settings for specific OEM
devices. Then renamed igb defines to be more generic, since the define
E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part.
Roland Hii fixes an issue where only the half cycle time of less than or
equal to 70 millisecond uses the I210 clock output function. His patch
adds additional conditions when half cycle time is equal to 125 or 250 or
500 millisecond to use the clock output function.
Alex Duyck adds support for generic transmit checksums for igb and igbvf.
Jon Maxwell fixes an issues where customer applications are registering
and un-registering multicast addresses every few seconds which is leading
to many "Link is up" messages in the logs as a result of the
netif_carrier_off(netdev) in igbvf_msix_other(). So remove the
link is up message when registering multicast addresses.
Corinna Vinschen provides a fix for when switching off VLAN offloading on
i350, the VLAN interface becomes unusable.
Stefan Assmann updates the driver to use ndo_stop() instead of
dev_close() when running ethtool offline self test. Since dev_close()
causes IFF_UP to be cleared which will remove the interfaces routes
and some addresses.
v2: Dropped patches 6-10 in the original series. Patch 6-7 added support
for character device for AVB and based on community feedback, we do not
want to do this. Patches 8-10 provided fixes to the problematic code
added in patches 6 & 7. So all of them must go!

On reviewing the code I realized that GRE and UDP tunnels could cause a
kernel panic if we used GSO to segment a large UDP frame that was sent
through the tunnel with an outer checksum and hardware offloads were not
available.
In order to correct this we need to update the feature flags that are
passed to the skb_segment function so that in the event of UDP
fragmentation being requested for the inner header the segmentation
function will correctly generate the checksum for the payload if we cannot
segment the outer header.

net: l3mdev: Fix source address for unnumbered deployments
David Lamparter noted a use case where the source address selection fails
to pick an address from a VRF interface - unnumbered interfaces. The use
case has the VRF device as the VRF local loopback with addresses and
interfaces enslaved without an address themselves. e.g,
ip addr add 9.9.9.9/32 dev lo
ip link set lo up
ip link add name vrf0 type vrf table 101

ip rule add iif vrf0 table 101
ip link set vrf0 up
ip addr add 10.0.0.3/32 dev vrf0
ip link add name dummy2 type dummy
ip link set dummy2 master vrf0 up
--> note dummy2 has no address - unnumbered device
ip route add 10.2.2.2/32 dev dummy2 table 101
ip neigh add 10.2.2.2 dev dummy2 lladdr 02:00:00:00:00:02
ping to the 10.2.2.2 through the L3 domain:
$ ping -I vrf0 -c1 10.2.2.2
ping: Warning: source address might be selected on device other than vrf0.
PING 10.2.2.2 (10.2.2.2) from 9.9.9.9 vrf0: 56(84) bytes of data.
picks up the wrong address -- the one from 'lo' not vrf0. And from tcpdump:
12:57:29.449128 IP 9.9.9.9 > 10.2.2.2: ICMP echo request, id 2491, seq 1, length 64
This patch series changes address selection to only consider devices in
the same L3 domain and to use the VRF device as the L3 domains loopback.
$ ping -I vrf0 -c1 10.2.2.2
PING 10.2.2.2 (10.2.2.2) from 10.0.0.3 vrf0: 56(84) bytes of data.

When selecting an address in context of a VRF, the vrf master should be
preferred for address selection. If it isn't, the user has a hard time
getting the system to select to their preference - the code will pick
the address off the first in-VRF interface it can find, which on a
router could well be a non-routable address.

Now the source address comes from vrf0.
The ipv4 function for selecting source address takes a const argument.
Removing the const requires touching a lot of places, so instead
l3mdev_master_ifindex_rcu is changed to take a const argument and then
do the typecast to non-const as required by netdev_master_upper_dev_get_rcu.
This is similar to what l3mdev_fib_table_rcu does.
IPv6 for unnumbered interfaces appears to be selecting the addresses
properly.

v4
- removed typedef for link mode bitmaps
- moved bitmap<->u32[] conversion routines to bitmap.c . This is the
naive implementation. I have an endian-aware version that uses
memcpy/memset as much as possible, but I find it harder to follow
(see http://paste.ubuntu.com/13863722/). Please let me know if I
should use it instead.
- fixes suggested by Ben Hutchings
v3
- rebased v2 on top of latest net-next, minor checkpatch/printf %*pb
updates
v2
- keep return 0 in get_settings when successful, instead of
propagating positive result from driver's get_settings callback.
v1
- original submission
The main goal of this series is to support ethtool link mode masks
larger than 32 bits. It implements a new ioctl pair
(ETHTOOL_GLINKSETTINGS/SLINKSETTINGS), its associated callbacks
(get/set_link_ksettings) and a new struct ethtool_link_settings, which
should eventually replace legacy ethtool_cmd. Internally, the kernel
uses fixed length link mode masks defined at compilation time in
ethtool.h (for now: 31 bits), that can be increased by changing
__ETHTOOL_LINK_MODE_LAST in ethtool.h (absolute max is 4064 bits,
checked at compile time), and the user/kernel interface allows this
length to be arbitrary within 1..4064. This should allow some
flexibility without using too much heap/stack space, at the cost of a
small kernel/user handshake for the user to determine the sizes of
those bitmaps.
Along the way, I chose to drop in the new structure the 3 ethtool_cmd
fields marked "deprecated" (transceiver/maxrxpkt/maxtxpkt). They are
still available for old drivers via the (old) ETHTOOL_GSET/SSET API,
but are not available to drivers that switch to new API. Of those 3
fields, ethtool_cmd::transceiver seems to be still actively used by
several drivers, maybe we should not consider this field deprecated?
The 2 other fields are basically not used. This transition requires
some care in the way old and new ethtool talk to the kernel.
More technical details provided in the description for main patch. In
particular details about backward compatibility properties.
Some open questions:
- the kernel/interface multiplexes the "tell me the bitmap length"
handshake and the "give me the settings" inside the new
ETHTOOL_GLINKSETTINGS cmd. I was thinking of making this into 2
separate cmds: 1 cmd ETHTOOL_GKERNELPROPERTIES which would be
kernel-wide rather than device-specific, would return properties
like "length of the link mode bitmaps", and possibly others. And
ETHTOOL_GLINKSETTINGS would expect the proper bitmaps
- the link mode bitmaps are piggybacked at tail of the new struct
ethtool_link_settings. Since its user-visible definition does not
assume specific bitmap width, I am using a 0-length array as the
publicly visible placeholder. But then, the kernel needs to
specialize it (struct ethtool_link_ksettings) to specify its
current link mode masks. This means that kernel code is "littered"
with "ksettings->base.field" to access "field" inside
ethtool_settings:
+ I could use ethtool_link_settings everywhere (instead of a new
ethtool_ksettings) and an container_of accessor (or a plain cast)
to retrieve the link mode masks?
+ or: we could decide to make the link mode masks statically
bounded again, ie. make their width public, but larger than
current 32, and unchangeable forever. This would make everything
straightforward, but we might hit limits later, or have an
unneeded memory/stack usage for unused bits.
any preference?
- I foresee bugs where people use the legacy/deprecated SUPPORTED_x
macros instead of the new ETHTOOL_LINK_MODE_x_BIT enums in the new
get/set_link_ksettings callbacks. Not sure how to prevent problems
with this.
The only driver which was converted for now is mlx4. I am not
considering fcoe as fully converted, but I updated it a minima to be
able to remove __ethtool_get_settings, now known as
__ethtool_get_link_ksettings.
Tested with legacy and "future" ethtool on 64b x86 kernel and 32+64b
ethtool, and on a 32b x86 kernel + 32b ethtool.

This patch defines a new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API,
handled by the new get_link_ksettings/set_link_ksettings callbacks.
This API provides support for most legacy ethtool_cmd fields, adds
support for larger link mode masks (up to 4064 bits, variable length),
and removes ethtool_cmd deprecated
fields (transceiver/maxrxpkt/maxtxpkt).
This API is deprecating the legacy ETHTOOL_GSET/SSET API and provides
the following backward compatibility properties:
- legacy ethtool with legacy drivers: no change, still using the
get_settings/set_settings callbacks.
- legacy ethtool with new get/set_link_ksettings drivers: the new
driver callbacks are used, data internally converted to legacy
ethtool_cmd. ETHTOOL_GSET will return only the 1st 32b of each link
mode mask. ETHTOOL_SSET will fail if user tries to set the
ethtool_cmd deprecated fields to
non-0 (transceiver/maxrxpkt/maxtxpkt). A kernel warning is logged if
driver sets higher bits.
- future ethtool with legacy drivers: no change, still using the
get_settings/set_settings callbacks, internally converted to new data
structure. Deprecated fields (transceiver/maxrxpkt/maxtxpkt) will be
ignored and seen as 0 from user space. Note that that "future"
ethtool tool will not allow changes to these deprecated fields.
- future ethtool with new drivers: direct call to the new callbacks.
By "future" ethtool, what is meant is:
- query: first try ETHTOOL_GLINKSETTINGS, and revert to ETHTOOL_GSET if
fails
- set: query first and remember which of ETHTOOL_GLINKSETTINGS or
ETHTOOL_GSET was successful
+ if ETHTOOL_GLINKSETTINGS was successful, then change config with
ETHTOOL_SLINKSETTINGS. A failure there is final (do not try
ETHTOOL_SSET).
+ otherwise ETHTOOL_GSET was successful, change config with
ETHTOOL_SSET. A failure there is final (do not try
ETHTOOL_SLINKSETTINGS).
The interaction user/kernel via the new API requires a small
ETHTOOL_GLINKSETTINGS handshake first to agree on the length of the link
mode bitmaps. If kernel doesn't agree with user, it returns the bitmap
length it is expecting from user as a negative length (and cmd field is
0). When kernel and user agree, kernel returns valid info in all
fields (ie. link mode length > 0 and cmd is ETHTOOL_GLINKSETTINGS).
Data structure crossing user/kernel boundary is 32/64-bit
agnostic. Converted internally to a legal kernel bitmap.
The internal __ethtool_get_settings kernel helper will gradually be
replaced by __ethtool_get_link_ksettings by the time the first
"link_settings" drivers start to appear. So this patch doesn't change
it, it will be removed before it needs to be changed.

This patch add the SO_CNX_ADVICE socket option (setsockopt only). The
purpose is to allow an application to give feedback to the kernel about
the quality of the network path for a connected socket. The value
argument indicates the type of quality report. For this initial patch
the only supported advice is a value of 1 which indicates "bad path,
please reroute"-- the action taken by the kernel is to call
dst_negative_advice which will attempt to choose a different ECMP route,
reset the TX hash for flow label and UDP source port in encapsulation,
etc.
This facility should be useful for connected UDP sockets where only the
application can provide any feedback about path quality. It could also
be useful for TCP applications that have additional knowledge about the
path outside of the normal TCP control loop.

flush all addresses to maintain backwards compatibility. When the set global
addresses with no expire times are not flushed on an admin down. The sysctl
is per-interface or system-wide for all interfaces
$ sysctl -w net.ipv6.conf.eth1.keep_addr_on_down=1

When the TIPC module is unloaded, we have identified a race condition
that allows a node reference counter to go to zero and the node instance
being freed before the node timer is finished with accessing it. This
leads to occasional crashes, especially in multi-namespace environments.
The scenario goes as follows:
CPU0:(node_stop) CPU1:(node_timeout) // ref == 2
1: if(!mod_timer())
2: if (del_timer())
3: tipc_node_put() // ref -> 1
4: tipc_node_put() // ref -> 0
5: kfree_rcu(node);
6: tipc_node_get(node)
7: // BOOM!
We now clean up this functionality as follows:
1) We remove the node pointer from the node lookup table before we
attempt deactivating the timer. This way, we reduce the risk that
tipc_node_find() may obtain a valid pointer to an instance marked
for deletion; a harmless but undesirable situation.
2) We use del_timer_sync() instead of del_timer() to safely deactivate
the node timer without any risk that it might be reactivated by the
timeout handler. There is no risk of deadlock here, since the two
functions never touch the same spinlocks.
3: We remove a pointless tipc_node_get() + tipc_node_put() from the
timeout handler.

any risk of post-mortem access.

A bug was introduced in the merge commit b633353115 ("Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net")
The generic marvell_config_init (and therefore marvell_of_reg_init) is
not called anymore for the Marvell 88E1510 (in net-next).
This patch calls marvell_config_init and moves the specific init
function for the 88E1510 below the marvell_config_init function to avoid
adding a function predeclaration.

net: dsa: add port VLAN dump operation
The VLAN GetNext approach is specific to some switches and thus hard to
implement for others. This patchset replaces it with a simpler port VLAN dump
operation, similar to the corresponding FDB operation.
The mv88e6xxx driver is the only one currently affected by the change.
The documentation is updated accordingly.
Note: this patchset uses http://www.spinics.net/lists/kernel/msg2186705.html

The VLAN GetNext operation is specific to some switches, and thus can be
complicated to implement for some drivers.
Remove the support for the vlan_getnext/port_pvid_get approach in favor
of the generic and simpler port_vlan_dump function.
