This patch adds support for ECMP hash policy choice via a new sysctl
called fib_multipath_hash_policy and also adds support for L4 hashes.
The current values for fib_multipath_hash_policy are:
0 - layer 3 (default)
1 - layer 4
If there's an skb hash already set and it matches the chosen policy then it
will be used instead of being calculated (currently only for L4).
In L3 mode we always calculate the hash due to the ICMP error special
case, the flow dissector's field consistentification should handle the
address order thus we can remove the address reversals.
If the skb is provided we always use it for the hash calculation,
otherwise we fallback to fl4, that is if skb is NULL fl4 has to be set.

wanted_features is a set of features which have to be enabled if a
hardware allows that.
Currently when a vlan device is created, its wanted_features is set to
current features of its base device.
The problem is that the base device can get new features and they are
not propagated to vlan-s of this device.
If we look at bonding devices, they doesn't have this problem and this
patch suggests to fix this issue by the same way how it works for bonding
devices.
We meet this problem, when we try to create a vlan device over a bonding
device. When a system are booting, real devices require time to be
initialized, so bonding devices created without slaves, then vlan
devices are created and only then ethernet devices are added to the
bonding device. As a result we have vlan devices with disabled
scatter-gather.
* create a bonding device
$ ip link add bond0 type bond
$ ethtool -k bond0 | grep scatter
scatter-gather: off
tx-scatter-gather: off [requested on]
tx-scatter-gather-fraglist: off [requested on]
* create a vlan device
$ ip link add link bond0 name bond0.10 type vlan id 10
$ ethtool -k bond0.10 | grep scatter
scatter-gather: off
tx-scatter-gather: off
tx-scatter-gather-fraglist: off
* Add a slave device to bond0
$ ip link set dev eth0 master bond0
And now we can see that the bond0 device has got the scatter-gather
feature, but the bond0.10 hasn't got it.
[root@laptop linux-task-diag]# ethtool -k bond0 | grep scatter
scatter-gather: on
tx-scatter-gather: on
tx-scatter-gather-fraglist: on
[root@laptop linux-task-diag]# ethtool -k bond0.10 | grep scatter
scatter-gather: off
tx-scatter-gather: off
tx-scatter-gather-fraglist: off
With this patch the vlan device will get all new features from the
bonding device.
Here is a call trace how features which are set in this patch reach
dev->wanted_features.

Dmitry has reported that a BUG_ON() condition in unix_notinflight()
may be triggered by a simple code that forwards unix socket in an
SCM_RIGHTS message.
That is caused by incorrect unix socket GC implementation in unix_gc().
The GC first collects list of candidates, then (a) decrements their
"children's" inflight counter, (b) checks which inflight counters are
now 0, and then (c) increments all inflight counters back.
(a) and (c) are done by calling scan_children() with inc_inflight or
dec_inflight as the second argument.
Commit 6209344f5a ("net: unix: fix inflight counting bug in garbage
collector") changed scan_children() such that it no longer considers
sockets that do not have UNIX_GC_CANDIDATE flag. It also added a block
of code that that unsets this flag _before_ invoking
scan_children(, dec_iflight, ). This may lead to incorrect inflight
counters for some sockets.
This change fixes this bug by changing order of operations:
UNIX_GC_CANDIDATE is now unset only after all inflight counters are
restored to the original state.

vsock: cancel connect packets when failing to connect
Currently, if a connect call fails on a signal or timeout (e.g., guest is still
in the process of starting up), we'll just return to caller and leave the connect
packet queued and they are sent even though the connection is considered a failure,
which can confuse applications with unwanted false connect attempt.
The patchset enables vsock (both host and guest) to cancel queued packets when
a connect attempt is considered to fail.
v5 changelog:
- change virtio_vsock_pkt->cancel_token back to virtio_vsock_pkt->vsk
v4 changelog:
- drop two unnecessary void * cast
- update new callback comment
v3 changelog:
- define cancel_pkt callback in struct vsock_transport rather than struct virtio_transport
- rename virtio_vsock_pkt->vsk to virtio_vsock_pkt->cancel_token

Otherwise we'll leave the packets queued until releasing vsock device.
E.g., if guest is slow to start up, resulting ETIMEDOUT on connect, guest
will get the connect requests from failed host sockets.

Subject: netlink: Annotate nlk cb_mutex by protocol
Currently all occurences of nlk->cb_mutex are annotated by lockdep
as a single class. This causes a false lcokdep cycle involving
genl and crypto_user.
This patch fixes it by dividing cb_mutex into individual classes
based on the netlink protocol. As genl and crypto_user do not
use the same netlink protocol this breaks the false dependency
loop.

40GbE Intel Wired LAN Driver Updates 2017-03-20
This series contains updates to i40e and i40evf only.
Philippe Reynes updates i40e and i40evf to use the new ethtool API for
{get|set}_link_ksettings.
Jake provides the remaining patches in the series, starting with a fix
for i40e where the firmware expected the port numbers for the offloaded
UDP tunnels in Little Endian format and we were sending them in Big Endian
format which put the wrong port number to be put in the UDP tunnel list.
Changed the driver to use __be32 values instead of arrays for
(src|dst)_ip. Refactored the exit flow of i40e_add_fdir_ethtool() which
removes the dependency on having a non-zero return value. Fixed a memory
leak by running kfree() and returning immediately when we fail to add
flow director filter. Fixed a potential issue where could update the
filter count without actually succeeding in adding a filter, by moving
the ATR exit check to after we have sent the TCP/IPv4 filter to the ring
successfully. Ensures that the fd_tcp_rule count is reset to 0, before
we reprogram the filters so that we do not end up with a stale count
which does not correctly reflect the number of programmed filters. Added
a check whether we have TCP/IPv4 filters before re-enabling ATR after
flushing and replaying FDIR filters. Added counters for each filter
type in preparation for adding code to properly check the mask value.
Fixed potential issues by explicitly checking the flow type at the
start of i40e_add_fdir_ethtool(). To avoid possible memory leaks,
we now unconditionally delete the old filter, even if it is identical to
the new filter and ensures will always update the filters as expected.

1GbE Intel Wired LAN Driver Updates 2017-03-17
This series contains updates to mainly igb, with one fix for ixgbe.
Alex does all the changes in the series, starting with adding support
for DMA_ATTR_WEAK_ORDERING to improve performance on some platforms.
Modified igb to use the length of the packet instead of the DD status
bit to determine if a new descriptor is ready to be processed. Modified
the driver to only go through the region in the receive ring that was
designated to be cleaned up, instead of going through the entire ring
on cleanup. Cleaned up the transmit side, by clearing the transmit
buffer_info only when resetting the rings. Added a new upper limit for
receive, which is based on the size of a 2K buffer minus padding, which
will allow us to support build_skb going forward. Fixed ethtool testing
to only sync on the size of the frame that is being tested, instead of
the entire receive buffer. Updated the handling of page addresses to
always use a void pointer with the consistent name of "va" to indicate
that we are working with a virtual address. Added a "chicken bit" so
that we can turn off the new receive allocation feature, in the case
where we need to fallback to the legacy receive path. Added support for
using 3K buffers in order 1 pages the same way we were using 2K buffers
in 4K pages. Added support for padding packet, since we limit the size
of the frame, we are able to write to an offset within the buffer instead
of having to write at the very start of the buffer. This allows us to
leaving padding room for things like supporting XDP in the future.
Refactored the receive buffer page management, since there are 2-3 paths
that can be taken depending on what receive modes are enabled, so to
improve maintainability, break out the common bits into their own
functions. Add support for build_skb, again. Lastly, fixed a typo in
igb and ixgbe code comments.

This is raised by the BUG_ON(!swap_slot_cache_initialized) in
free_swap_slot(). This is incorrect, because even if the swap slots
cache fails to be initialized, the swap should operate properly without
the swap slots cache. And the use_swap_slot_cache check later in the
function will protect the uninitialized swap slots cache case.
In commit 452b94b8c8, the BUG_ON() is replaced by WARN_ON_ONCE(). In
the patch, the WARN_ON_ONCE() is removed too.

This hits the ST serial driver in drivers/tty/serial and that has an

smoothen things in the merge Windod and those have now served their

When snd_seq_pool_done() is called, it marks the closing flag to
refuse the further cell insertions. But snd_seq_pool_done() itself
doesn't clear the cells but just waits until all cells are cleared by
the caller side. That is, it's racy, and this leads to the endless
stall as syzkaller spotted.
This patch addresses the racy by splitting the setup of pool->closing
flag out of snd_seq_pool_done(), and calling it properly before
snd_seq_pool_done().

CONFIG_SND_X86 is a menu config to filter only for x86-specific
drivers in its sub-menu, and this doesn't have to be tristate but
rather it should be a bool. Also, like other sub-menu configs, it's
more user-friendly to be default=y; it's merely a menu config and the
actual drivers are configured in the sub-menu, after all.

The previous code relied on i40e_match_fdir_input_set to determine when
determining whether to free the old filter. Change this code so that we
simply unconditionally delete the old filter, even if it's identical to
the new filter. This ensures that we don't leak any memory, and that we
always update the filters as expected.

Although we will fail the filter later due to checking flow_type which
will have a bogus invalid type, it is possible future refactoring will
remove this hidden failure case. Avoid a possible issue in the future by
explicitly checking the flow type at the start.

In preparation for adding code to properly check the mask values, we
will need to know the number of active filters for each type. Add
counters for each filter type. Rename the already existing fd_tcp_rule
to fd_tcp4_filter_cnt to match the style of other names. To avoid style
warnings, avoid assigning multiple parameters at once, and fix up one
other case where we did so previously.

When flushing and replaying FDIR filters, it is possible we would
disable ATR, and then re-enable it even though we should have kept
it disabled due to existing TCP/IPv4 filters. Fix this by checking
whether we have TCP4/IPv4 filters before re-enabling.
Alternatively, we could instead restore ATR and then replay filters,
however, this would cause us to rapidly enable and then disable ATR in
some cases.

Move ATR exit check after we have sent the TCP/IPv4 filter to the ring
successfully. This avoids an issue where we potentially update the
filter count without actually succeeding in adding the filter. Now, we
only increment the fd_tcp_rule after we've succeeded. Additionally, we
will re-enable ATR mode only after deletion of the filter is actually
posted to the FDIR ring.

Instead of setting err=true and checking this to determine when to free
the raw_packet near the end of the function, simply kfree and return
immediately. The resulting code is a bit cleaner and has one less
variable. This also resolves a subtle bug in the ipv4 case which could
fail to add the first filter and then never free the memory, resulting
in a small memory leak.
