In practice struct netns_ipvs is as meaningful as struct net and more
useful as it holds the ipvs specific data. So store a pointer to
struct netns_ipvs.Update the accesses of param->net to access param->ipvs->net instead.
In functions where we are searching for an svc and filtering by net
filter by ipvs instead.Signed-off-by: "Eric W. Biederman"

====================
Netfilter/IPVS updates for net-nextThe following patchset contains Netfilter/IPVS updates for your net-next tree
in this 4.4 development cycle, they are:1) Schedule ICMP traffic to IPVS instances, this introduces a new schedule_icmp
proc knob to enable/disable it. By default is off to retain the old
behaviour. Patchset from Alex Gartrell.I'm also including what Alex originally said for the record:
"The configuration of ipvs at Facebook is relatively straightforward. All
ipvs instances bgp advertise a set of VIPs and the network prefers the
nearest one or uses ECMP in the event of a tie. For the uninitiated, ECMP
deterministically and statelessly load balances by hashing the packet
(usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using
that number as an index (basic hash table type logic).The problem is that ICMP packets (which contain really important
information like whether or not an MTU has been exceeded) will get a
different hash value and may end up at a different ipvs instance. With no
information about where to route these packets, they are dropped, creating
ICMP black holes and breaking Path MTU discovery. Suddenly, my mom's
pictures can't load and I'm fielding midday calls that I want nothing to do
with.To address this, this patch set introduces the ability to schedule icmp
packets which is gated by a sysctl net.ipv4.vs.schedule_icmp. If set to 0,
the old behavior is maintained -- otherwise ICMP packets are scheduled."2) Add another proc entry to ignore tunneled packets to avoid routing loops
from IPVS, also from Alex.3) Fifteen patches from Eric Biederman to:
* Stop passing nf_hook_ops as parameter to the hook and use the state hook
object instead all around the netfilter code, so only the private data
pointer is passed to the registered hook function.* Now that we've got state->net, propagate the netns pointer to netfilter hook
clients to avoid its computation over and over again. A good example of how
this has been simplified is the former TEE target (now nf_dup infrastructure)
since it has killed the ugly pick_net() function.There's another round of netns updates from Eric Biederman making the line. To
avoid the patchbomb again to almost all the networking mailing list (that is 84
patches) I'd suggest we send you a pull request with no patches or let me know
if you prefer a better way.

This patch makes TLP to use 1 sec timer by default when RTT is
not available due to SYN/ACK retransmission or SYN cookies.Prior to this change, the lack of RTT prevents TLP so the first
data packets sent can only be recovered by fast recovery or RTO.
If the fast recovery fails to trigger the RTO is 3 second when
SYN/ACK is retransmitted. With this patch we can trigger fast
recovery in 1sec instead.Note that we need to check Fast Open more properly. A Fast Open
connection could be (accepted then) closed before it receives
the final ACK of 3WHS so the state is FIN_WAIT_1. Without the
new check, TLP will retransmit FIN instead of SYN/ACK.Signed-off-by: Yuchung Cheng

Currently SYN/ACK RTT is measured in jiffies. For LAN the SYN/ACK
RTT is often measured as 0ms or sometimes 1ms, which would affect
RTT estimation and min RTT samping used by some congestion control.This patch improves SYN/ACK RTT to be usec resolution if platform
supports it. While the timestamping of SYN/ACK is done in request
sock, the RTT measurement is carefully arranged to avoid storing
another u64 timestamp in tcp_sock.For regular handshake w/o SYNACK retransmission, the RTT is sampled
right after the child socket is created and right before the request
sock is released (tcp_check_req() in tcp_minisocks.c)For Fast Open the child socket is already created when SYN/ACK was
sent, the RTT is sampled in tcp_rcv_state_process() after processing
the final ACK an right before the request socket is released.If the SYN/ACK was retransmistted or SYN-cookie was used, we rely
on TCP timestamps to measure the RTT. The sample is taken at the
same place in tcp_rcv_state_process() after the timestamp values
are validated in tcp_validate_incoming(). Note that we do not store
TS echo value in request_sock for SYN-cookies, because the value
is already stored in tp->rx_opt used by tcp_ack_update_rtt().One side benefit is that the RTT measurement now happens before
initializing congestion control (of the passive side). Therefore
the congestion control can use the SYN/ACK RTT.Signed-off-by: Yuchung Cheng

s390: qeth and iucv patcheshere is version 2 of some s390 related qeth patches for net-next. The patch by
Thomas Richter adds a new feature to the qeth layer2 code; the remaining
patches are minor improvements.
Version 2 of patch 4 uses the desired indentation in function declarations
and definitions spanning multiple lines in almost all cases. Thomas run into a
conflict with the maximum number of columns once. Thus you will still see one
function definition using an earlier column before the opening paranthesis.

The iucv code uses arrays as arguments. Even though this does not

Checksum offloading for send and receive is already
supported for layer 3 (IP layer). This patch
adds support for RX and TX hardware checksum offloading
for layer 2 (MAC layer). The hardware calculates the checksum
for IP UDP and TCP packets.This patch moves the hardware checksum offloading setup
to the set of common functions in qeth_core_main.c.
Layer 2 and layer 3 now simply call the same common functions.Also note that TX checksum offloading is always enabled.
The device driver relies on the TCP/IP stack to make use of
this feature.Signed-off-by: Thomas Richter
