Vipul Pandya 94dace1014 cxgb4vf: Support CPL_SGE_EGR_UPDATEs encapsulated in a CPL_FW4_MSG
Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a
CPL_FW4_MSG as follows

flit0 rss_header (if DropRSS == 0 in IQ context)
flit1 CPL_FW4_MSG cpl
flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE
flit3 CPL_SGE_EGR_UPDATE cpl

So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the
CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still
post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle
both.

This patch also writes a new parameter to firmware requesting encapsulated
EGR_UPDATE. This allows firmware with this support to not break older drivers.

Yuchung Cheng cd75eff64d tcp: reset timer after any SYNACK retransmit
Linux immediately returns SYNACK on (spurious) SYN retransmits, but
keeps the SYNACK timer running independently. Thus the timer may
fire right after the SYNACK retransmit and causes a SYN-SYNACK
cross-fire burst.

Adopt the fast retransmit/recovery idea in established state by
re-arming the SYNACK timer after the fast (SYNACK) retransmit. The
timer may fire late up to 500ms due to the current SYNACK timer wheel,
but it's OK to be conservative when network is congested. Eric's new
listener design should address this issue.

John W. Linville a8a48e60a4 With this one we have:
- One patch for moving the LLCP code into net/nfc.
   It fixes a build annoyance reported by Dave Miller caused by the fact
   that the LLCP code object targets are not in the same directory as the
   Makefile trying to build them is. It prevents us from doing e.g.
 
         make net/nfc/llcp/sock.o
 
   Moving the LLCP code into net/nfc and not making it optional anymore
   makes sense as LLCP is a fundamental piece of the NFC specifications
   and thus should be in the core NFC directory.
 
 - One patch that fixes the missing dependency against RFKILL. Without it NFC
   fails to properly build when it's builtin and CONFIG_RFKILL=m.

Pablo Neira Ayuso says:

====================
The following patchset contains relevant updates for the Netfilter
tree, they are:

* Enhancements for ipset: Add the counter extension for sets, this
  information can be used from the iptables set match, to change
  the matching behaviour. Jozsef required to add the extension
  infrastructure and moved the existing timeout support upon it.
  This also includes a change in net/sched/em_ipset to adapt it to
  the new extension structure.

* Enhancements for performance boosting in nfnetlink_queue: Add new
  configuration flags that allows user-space to receive big packets (GRO)
  and to disable checksumming calculation. This were proposed by Eric
  Dumazet during the Netfilter Workshop 2013 in Copenhagen. Florian
  Westphal was kind enough to find the time to materialize the proposal.

* A sparse fix from Simon, he noticed it in the SCTP NAT helper, the fix
  required a change in the interface of sctp_end_cksum.

Simon Horman eee1d5a147 sctp: Correct type and usage of sctp_end_cksum()
Change the type of the crc32 parameter of sctp_end_cksum()
from __be32 to __u32 to reflect that fact that it is passed
to cpu_to_le32().

There are five in-tree users of sctp_end_cksum().
The following four had warnings flagged by sparse which are
no longer present with this change.

net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_nat_csum()
net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_csum_check()
net/sctp/input.c:sctp_rcv_checksum()
net/sctp/output.c:sctp_packet_transmit()

The fifth user is net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt().
It has been updated to pass a __u32 instead of a __be32,
the value in question was already calculated in cpu byte-order.

net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt() has also
been updated to assign the return value of sctp_end_cksum()
directly to a variable of type __le32, matching the
type of the return value. Previously the return value
was assigned to a variable of type __be32 and then that variable
was finally assigned to another variable of type __le32.

Problems flagged by sparse.
Compile and sparse tested only.

Once we allow userspace to receive gso/gro packets, userspace
needs to be able to determine when checksums appear to be
broken, but are not.

NFQA_SKB_CSUMNOTREADY means 'checksums will be fixed in kernel
later, pretend they are ok'.

NFQA_SKB_GSO could be used for statistics, or to determine when
packet size exceeds mtu.

Florian Westphal a5fedd43d5 netfilter: move skb_gso_segment into nfnetlink_queue module
skb_gso_segment is expensive, so it would be nice if we could
avoid it in the future. However, userspace needs to be prepared
to receive larger-than-mtu-packets (which will also have incorrect
l3/l4 checksums), so we cannot simply remove it.

The plan is to add a per-queue feature flag that userspace can
set when binding the queue.

The problem is that in nf_queue, we only have a queue number,
not the queue context/configuration settings.

This patch should have no impact other than the skb_gso_segment
call now being in a function that has access to the queue config
data.

A new size attribute in nf_queue_entry is needed so
nfnetlink_queue can duplicate the entry of the gso skb
when segmenting the skb while also copying the route key.

The follow up patch adds switch to disable skb_gso_segment when
queue config says so.

Haiyang Zhang 00ca8f0c9d hyperv: Fix a compiler warning in netvsc_send()
Fixed: warning: cast from pointer to integer of different size

The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64
bit pointers which equal to the ulong type size. So we cast it to ulong type.
And, assigning 32bit integer to 64 bit variable works fine.

The VMBus returns the same id in the completion packet. But the value has no
effect on the host side.

Special flags were employed to distinguish between both, but due to flawed

[get|set]_registers() are now much simpler.  Async write is also leaner
and does not use single, statically allocated memory for usb_ctrlrequest,

Note that we check CAP_SYS_ADMIN before allowing to dump this info.

For now, only AF_PACKET sockets use this feature.

Nicolas Dichtel 76d0eeb1a1 packet_diag: disclose meminfo values
sk_rmem_alloc is disclosed via /proc/net/packet but not via netlink messages.
The goal is to have the same level of information.

Daniel Borkmann fdd5f43a1b selftests: psock_tpacket: fix status check
Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug
since it always returns true. Fix this by only checking for flags
where the kernel owns the packet and negate this result, since we
also could run into the non-zero status TP_STATUS_WRONG_FORMAT
and need to reclaim frames.

stephen hemminger 7d836a7679 vxlan: compute source port in network byte order
Rather than computing source port and returning it in host order
then swapping later, go ahead and compute it in network order to
start with. Cleaner and less error prone.

stephen hemminger 5d174dd80c vxlan: source compatiablity with IFLA_VXLAN_GROUP (v2)
Source compatiability for build iproute2 was broken by:
  commit c7995c43fa
  Author: Atzm Watanabe <atzm@stratosphere.co.jp>
    vxlan: Allow setting destination to unicast address.

Since this commit has not made it upstream (still net-next),
and better to avoid gratitious changes to exported API's;
go back to original definition, and add a comment.

stephen hemminger 73cf331706 vxlan: fix byte order issues with NDA_PORT
The NDA_PORT attribute was added, but the author wasn't careful
about width (port is 16 bits), or byte order.  The attribute was
being dumped as 16 bits, but only 32 bit value would be accepted
when setting up a device. Also, the remote port is in network
byte order and was being compared with default port in host byte
order.
