pull request: wireless-next 2014-01-01

These patches were tucked-in with me for my long winter's nap!
Please pull them for the 3.14 stream...

For the mac80211 bits, Johannes says:

"Here I just have a collection of fixes/improvements/cleanups, very
little really stands out apart from CSA fixes, vendor command support
and the RCU speedups."

For the iwlwifi bits, Emmanuel says:

"I have hear quite a few things. Alex continues his work on power
management. Arik is reworking the transport API by unifying redudant
APIs and making error handling more generic. Eyal keeps on digging in
the rate scaling code.
We also have two new features - Max is using the brand new generic
cipher infrastructure in mac80211, and Lilach implements the smart fifo
which allows to save power by making interrupt coalescing smarter."

Along with those, Arend and company bring a batch of brcmfmac.
Sujith and Felix bring the usual high level of ath9k activity as well.
Bing gives mwifiex some love as well, and a handful of other bits
get updates here and there.

The buffer that is used to pass doorbell offset to the userspace UIO
driver may contain nonzero value in older versions of bnx2x driver.
Userspace cannot easily tell whether it contains a valid doorbell
offset or not.  With the added signature, userspace will only use
the doorbell offset if the signature is present.

Update version to 2.5.19.

The current code does not reset the advertisement register when the speed
is forced, leaving the default advertisement value of 10 Mbps.  This does
not work with some link partners when the next patch enables auto-mdix.

slight optimization of addr compare for net modules

This is the second patchset for slight optimization of address compare,
mainly for net tree, just following the Joe's opinion, it will help review
the code for maintainers and supports.

v2: Change some style for patch 2.
    According Eric's suggestion, use the ether_addr_equal_64bits to instead
    of ether_addr_equal for patch 19.
    In fact, there are a lot of places which could use ether_addr_equal_64bits
    to instead of ether_addr_equal, but not this time, thanks for Joe's
    opinion.

v3: Change some style for patch 11/19:
    (net: packetengines: slight optimization of addr compare).
    Joe pointed out that is_broadcast_ether_addr(addr) would be appropriate here,
    but this should be left alone and not in this patch, so fix it later.

    In the patch (net: caif: slight optimization of addr compare), the operand for
    memcmp is not mac address, so it is unsuitable to use the ether_addr_equal
    to compare a non mac address, so remove the patch from the series.

When the device tunneling offloads mode is vxlan do the following

 - call SET_PORT with the relevant setting

 - add DMFS steering vxlan rule for the device self and multicast mac addresses
   of the form: {<ETH, outer-mac> <VXLAN, ANY vnid> <ETH, ANY mac>} --> RSS QP

 - set relevant QPC fields in RSS context and RX ring QPs

 - in TX flow, set WQE fields to generate HW checksum, and handle gso skbs
   which are marked for encapsulation such that the HW will segment them properly.

 - in RX flow, read HW offloaded checksum for encapsulated packets from the CQE

 - advertize hw_enc_features and NETIF_F_GSO_UDP_TUNNEL to the networking stack

Add the low-level device commands and definitions used for TCP/IP HW offloads
of tunneled/vxlan traffic which are supported by the ConnectX3-pro NIC.

This is done through the following elements:

 - read tunneling device caps in QUERY_DEV_CAP
 - add helper function to do SET_PORT for tunneling
 - add DMFS VXLAN steering rule definitions
 - add CQE and WQE checksum offload field definitions

In order to facilitate development for netlink protocol dissector,
fill the unused field skb->pkt_type of the cloned skb with a hint
of the address space of the new owner (receiver) socket in the
notion of "to kernel" resp. "to user".

At the time we invoke __netlink_deliver_tap_skb(), we already have
set the new skb owner via netlink_skb_set_owner_r(), so we can use
that for netlink_is_kernel() probing.

In normal PF_PACKET network traffic, this field denotes if the
packet is destined for us (PACKET_HOST), if it's broadcast
(PACKET_BROADCAST), etc.

As we only have 3 bit reserved, we can use the value (= 6) of
PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel
and not supported anywhere, and packets of such type were never
exposed to user space, so there are no overlapping users of such
kind. Thus, as wished, that seems the only way to make both
PACKET_* values non-overlapping and therefore device agnostic.

By using those two flags for netlink skbs on nlmon devices, they
can be made available and picked up via sll_pkttype (previously
unused in netlink context) in struct sockaddr_ll. We now have
these two directions:

 - PACKET_USER (= 6)    ->  to user space
 - PACKET_KERNEL (= 7)  ->  to kernel space

Partial `ip a` example strace for sa_family=AF_NETLINK with
detected nl msg direction:

syscall:                     direction:
sendto(3,  ...) = 40         /* to kernel */
recvmsg(3, ...) = 3404       /* to user */
recvmsg(3, ...) = 1120       /* to user */
recvmsg(3, ...) = 20         /* to user */
sendto(3,  ...) = 40         /* to kernel */
recvmsg(3, ...) = 168        /* to user */
recvmsg(3, ...) = 144        /* to user */
recvmsg(3, ...) = 20         /* to user */

We should also deliver packets to nlmon devices when we are in

sctp: Consolidate and ratelimit deprecation warnings

The SCTP protocol has several deprecation warnings in its setsockopt path that
can be triggered by unprivlidged users.  Since these are not ratelimited, we can
spam the logs quite easily here.  Since these are all deprecation warnings, and
that type of warning isn't uncommon in the rest of the kernel, lets make a
common pr_warn_deprecated macro to produce somewhat generalized ratelimited
deprecation warnings easily
====================
Signed-off-by: Neil Horman <nhorman@tuxdriver.com>
Signed-off-by: David S. Miller <davem@davemloft.net>

During a recent discussion regarding some sctp socket options, it was noted that
we have several points at which we issue log warnings that can be flooded at an
unbounded rate by any user.  Fix this by converting all the pr_warns in the
sctp_setsockopt path to be pr_warn_ratelimited.

Note there are several debug level messages as well.  I'm leaving those alone,
as, if you turn on pr_debug, you likely want lots of verbosity.
