Steffen Klassert says:

====================
1) Don't use a wildcard SA if a more precise one is in acquire state,
   from Fan Du.

2) Simplify the SA lookup when using wildcard source. We need to check
   only the destination in this case, from Fan Du.

3) Add a receive path hook for IPsec virtual tunnel interfaces
   to xfrm6_mode_tunnel.

4) Add support for IPsec virtual tunnel interfaces to ipv6.

60d3c47310 qlcnic: Skip unknown entry type while collecting firmware dump
o Driver aborts the minidump collection operation when it finds
  an unknown entry opcode. This patch skips unknown entry type
  and resumes the minidump collection operation.
o Removed a comparision of collected dump size with expected dump size.
  Size may differ when driver decides to skip an entry.

bbfbe47cc9 tipc: simplify the link lookup routine
When checking statistics or changing parameters on a link, the
link_find_link function is used to locate the link with a given
name. The complex method of deconstructing the name into local
and remote address/interface is error prone and may fail if the
interface names contains special characters. We change the lookup
method to iterate over the list of nodes and compare the link
names.

636c0371a7 tipc: correct return value of link_cmd_set_value routine
link_cmd_set_value() takes commands for link, bearer and media related
configuration. Genereally the function returns 0 when a command is
recognized, and -EINVAL when it is not. However, in the switch for link
related commands it returns 0 even when the command is unrecognized. This
will sometimes make it look as if a failed configuration command has been
successful, but has otherwise no negative effects.

We remove this anomaly by returning -EINVAL even for link commands. We also
rework all three switches to make them  conforming to common kernel coding
style.

6798158348 tipc: correct return value of recv_msg routine
Currently, rcv_msg() always returns zero on a packet delivery upcall
from net_device.

To make its behavior more compliant with the way this API should be
used, we change this to let it return NET_RX_SUCCESS (which is zero
anyway) when it is able to handle the packet, and NET_RX_DROP otherwise.
The latter does not imply any functional change, it only enables the
driver to keep more accurate statistics about the fate of delivered
packets.

f2875c3cc4 tipc: avoid unnecessary lookup for tipc bearer instance
tipc_block_bearer() currently takes a bearer name (const char*)
as argument. This requires the function to make a lookup to find
the pointer to the corresponding bearer struct. In the current
code base this is not necessary, since the only two callers
(tipc_continue(),recv_notification()) already have validated
copies of this pointer, and hence can pass it directly in the
function call.

We change tipc_block_bearer() to directly take struct tipc_bearer*
as argument instead.

4babbaa8a1 tipc: make bearer and media naming consistent
TIPC 'bearer' exists as an abstract concept, while 'media'
is deemed a specific implementation of a bearer, such as Ethernet
or Infiniband media. When a component inside TIPC wants to control
a specific media, it only needs to access the generic bearer API
to achieve this. However, in the current media implementations,
the 'bearer' name is also extensively used in media specific
function and variable names.

This may create confusion, so we choose to replace the term 'bearer'
with 'media' in all function names, variable names, and prefixes
where this is what really is meant.

Note that this change is cosmetic only, and no runtime behaviour
changes are made here.

5c0a0fc81f tipc: don't use memcpy to copy from user space
tipc_msg_build() calls skb_copy_to_linear_data_offset() to copy data
from user space to kernel space. However, the latter function does
in its turn call memcpy() to perform the actual copying. This poses
an obvious security and robustness risk, since memcpy() never makes
any validity check on the pointer it is copying from.

To correct this, we the replace the offending function call with
a call to memcpy_fromiovecend(), which uses copy_from_user() to
perform the copying.

400dfd3ae8 net: refactor sk_page_frag_refill()
While working on virtio_net new allocation strategy to increase
payload/truesize ratio, we found that refactoring sk_page_frag_refill()
was needed.

This patch splits sk_page_frag_refill() into two parts, adding
skb_page_frag_refill() which can be used without a socket.

While we are at it, add a minimum frag size of 32 for
sk_page_frag_refill()

Michael will either use netdev_alloc_frag() from softirq context,
or skb_page_frag_refill() from process context in refill_work()
 (GFP_KERNEL allocations)

====================
This is a batch of updates intended for the 3.13 stream...

The biggest item of interest in here is wcn36xx, the new mac80211
driver for Qualcomm WCN3660/WCN3680 hardware.

Regarding the mac80211 bits, Johannes says:

"We have an assortment of cleanups and new features, of which the
biggest one is probably the channel-switch support in IBSS. Nothing
else really stands out much."

On top of that, the ath9k and rt2x00 get a lot of update action from
Felix Fietkau and Gabor Juhos, respectively.  There are a handful of
updates to other drivers here and there as well.

Please let me know if there are problems!

a946858768 xen-netback: handle IPv6 TCP GSO packets from the guest
This patch adds a xenstore feature flag, festure-gso-tcpv6, to advertise
that netback can handle IPv6 TCP GSO packets. It creates SKB_GSO_TCPV6 skbs
if the frontend passes an extra segment with the new type
XEN_NETIF_GSO_TYPE_TCPV6 added to netif.h.

7365bcfa32 xen-netback: Unconditionally set NETIF_F_RXCSUM
There is no mechanism to insist that a guest always generates a packet
with good checksum (at least for IPv4) so we must handle checksum
offloading from the guest and hence should set NETIF_F_RXCSUM.

2eba61d55e xen-netback: add support for IPv6 checksum offload from guest
For performance of VM to VM traffic on a single host it is better to avoid
calculation of TCP/UDP checksum in the sending frontend. To allow this this
patch adds the code necessary to set up partial checksum for IPv6 packets
and xenstore flag feature-ipv6-csum-offload to advertise that fact to
frontends.

Check xenstore flag feature-ipv6-csum-offload to determine if a
guest is happy to accept IPv6 packets with only partial checksum.

c0f4ace79e Merge branch 'bonding_rcu'
bonding: patchset for rcu use in bonding

====================
The Patch Set convert the xmit of 3ad and alb mode to use rcu lock.
dd rtnl lock and remove read lock for bond sysfs.

v2 because the bond_for_each_slave_rcu without rcu_read_lock() will occurs one warming, so
add new function for alb xmit path to avoid warming.

4d1ae5fb75 bonding: add rtnl lock and remove read lock for bond sysfs
The bond_for_each_slave() will not be protected by read_lock(),
only protected by rtnl_lock(), so need to replace read_lock()
with rtnl_lock().

The commit 278b208375
(bonding: initial RCU conversion) has convert the roundrobin,
active-backup, broadcast and xor xmit path to rcu protection,
the performance will be better for these mode, so this time,
convert xmit path for alb mode.
