Fabian reports a possible conntrack memory leak (could not reproduce so
far), however, one minor issue can be easily resolved:
> cat /proc/net/nf_conntrack | wc -l = 5
> 4 minutes required to clean up the table.
We should not report those timed-out entries to the user in first place.
And instead of just skipping those timed-out entries while iterating over
the table we can also zap them (we already do this during ctnetlink
walks, but I forgot about the /proc interface).

Create a new revision for the hashlimit iptables extension module. Rev 2
will support higher pps of upto 1 million, Version 1 supports only 10k.
To support this we have to increase the size of the variables avg and
burst in hashlimit_cfg to 64-bit. Create two new structs hashlimit_cfg2
and xt_hashlimit_mtinfo2 and also create newer versions of all the
functions for match, checkentry and destroy.
Some of the functions like hashlimit_mt, hashlimit_mt_check etc are very
similar in both rev1 and rev2 with only minor changes, so I have split
those functions and moved all the common code to a *_common function.

Currently, if the user want to match ct l3proto, we must specify the
direction, for example:
# nft add rule filter input ct original l3proto ipv4
^^^^^^^^
Otherwise, error message will be reported:
# nft add rule filter input ct l3proto ipv4
nft add rule filter input ct l3proto ipv4
<cmdline>:1:1-38: Error: Could not process rule: Invalid argument
add rule filter input ct l3proto ipv4
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Actually, there's no need to require NFTA_CT_DIRECTION attr, because
ct l3proto and protocol are unrelated to direction.
And for compatibility, even if the user specify the NFTA_CT_DIRECTION
attr, do not report error, just skip it.

It is valid that the TCP RST packet which does not set ack flag, and bytes
of ack number are zero. But current seqadj codes would adjust the "0" ack
to invalid ack number. Actually seqadj need to check the ack flag before
adjust it for these RST packets.
The following is my test case
client is 10.26.98.245, and add one iptable rule:
iptables -I INPUT -p tcp --sport 12345 -m connbytes --connbytes 2:
--connbytes-dir reply --connbytes-mode packets -j REJECT --reject-with
tcp-reset
This iptables rule could generate on TCP RST without ack flag.
server:10.172.135.55
Enable the synproxy with seqadjust by the following iptables rules
iptables -t raw -A PREROUTING -i eth0 -p tcp -d 10.172.135.55 --dport 12345
-m tcp --syn -j CT --notrack
iptables -A INPUT -i eth0 -p tcp -d 10.172.135.55 --dport 12345 -m conntrack

40GbE Intel Wired LAN Driver Updates 2016-09-24
This series contains updates to i40e and i40evf only.
Harshitha removes the ability to set or advertise X722 to 100 Mbps,
since it is not supported, so we should not be able to advertise or
set the NIC to 100 Mbps.
Alan fixes an issue where deleting a MAC filter did not really delete the
filter in question. The reason being that the wrong cmd_flag is passed to
the firmware.
Preethi adds the encapsulation checksum offload negotiation flag, so that
we can control it.
Jake cleans up the ATR auto_disable_flags use, since some locations
disable ATR accidentally using the "full" disable by disabling the flag
in the standard flags field. This permanently forces ATR off instead of
temporarily disabling it. Then updated checks to include when there are
TCP/IP4 sideband rules in effect, where ATR should be disabled. Lastly,
adds support to the i40evf driver for setting interrupt moderation values
per queue, like in i40e.
Henry cleans up unreachable code, since i40e_shutdown_adminq() is always
true.
Mitch enables support for adaptive interrupt throttling, since all the
code for it is already in the interrupt handler. The fixes a rare
case where we might get a VSI with no queues and we try to configure
RSS, which would result in a divide by zero.
Alex fixes an issue where transmit cleanup flow was incorrectly assuming
it could check for the flow director bits after it had unmapped the
buffer. Then adds a txring_txq() to allow us to convert a i40e_ring/
i40evf_ring to a netdev_tx_queue structure, like ixgbe and fm10k. This
avoids having to make a multi-line function call for all the areas that
need access to it. Re-factors the Flow Director filter configuration
out into a separate function, like we did for the standard xmit path.
Cleans up the debugfs hook for Flow Director since it was meant for
debug only.

rxrpc: Implement slow-start and other bits
This set of patches implements the RxRPC slow-start feature for AF_RXRPC to
improve performance and handling of occasional packet loss. This is more or
less the same as TCP slow start [RFC 5681]. Firstly, there are some ACK
generation improvements:
(1) Send ACKs regularly to apprise the peer of our state so that they can do
congestion management of their own.
(2) Send an ACK when we fill in a hole in the buffer so that the peer can
find out that we did this thus forestalling retransmission.
(3) Note the final DATA packet's serial number in the final ACK for
correlation purposes.
and a couple of bug fixes:
(4) Reinitialise the ACK state and clear the ACK and resend timers upon
entering the client reply reception phase to kill off any pending probe
ACKs.
(5) Delay the resend timer to allow for nsec->jiffies conversion errors.
and then there's the slow-start pieces:
(6) Summarise an ACK.
(7) Schedule a PING or IDLE ACK if the reply to a client call is overdue to
try and find out what happened to it.
(8) Implement the slow start feature.

The 8xx has two special registers called EID (External Interrupt
Disable) and EIE (External Interrupt Enable) for clearing/setting
EE in MSR. It avoids the three instructions set mfmsr/ori/mtmsr or
mfmsr/rlwinm/mtmsr and it avoids using a general register.
We just have to write something in the special register to change MSR EE
bit. So we write r0 into the register, regardless of r0 value.
Writing to one of those two special registers also set the MSR RI bit,
but this bit is only unset during beginning of exception prolog and end
of exception epilog. When executing C-functions MSR RI is always set.

Commit 0e6e01ff69 ("CPM/QE: use genalloc to manage CPM/QE muram")
has changed the way muram is managed.
genalloc uses kmalloc(), hence requires the SLAB to be up and running.
On powerpc 8xx, cpm_reset() is called early during startup.
cpm_reset() then calls cpm_muram_init() before SLAB is available,
hence the following Oops.
cpm_reset() cannot be called during initcalls because the CPM is
needed for console.
This patch removes the call to cpm_muram_init() from cpm_reset().
cpm_muram_init() will be called from a new function called cpm_init()
which is declared as subsys_initcall, unless cpm_muram_alloc() is
called earlier for the serial console in which case cpm_muram_init()
will be called from there.
The reason for calling it from two places is that some drivers
(e.g. i2c-cpm) need some of the initialisations done by
cpm_muram_init() but don't call cpm_muram_alloc(). The console
driver calls cpm_muram_alloc() but some platforms might not use
the CPM serial ports for console.
