Commit 016818d0 (tcp: TCP Fast Open Server - take SYNACK RTT after

when a SYNACK transmit or retransmit succeeds. This behaviour is later
broken by commit 843f4a55 (tcp: use tcp_v4_send_synack on first

fails.

Also, commit 3a19ce0e (tcp: IPv6 support for fastopen server) misses
the required IPv6 updates for 016818d0.

Intel Wired LAN Driver Updates 2014-06-26

This series contains updates to i40e and i40evf.

Kamil provides a cleanup patch to i40e where we do not need to acquire the
NVM for shadow RAM checksum calculation, since we only read the shadow RAM
through SRCTL register.

Paul provides a fix for handling HMC for big endian architectures for i40e
and i40evf.

Mitch provides four cleanup and fixes for i40evf.  Fix an issue where if
the VF driver fails to complete early init, then rmmod can cause a softlock
when the driver tries to stop a watchdog timer that never got initialized.
So add a check to see if the timer is actually initialized before stopping
it.  Make the function i40evf_send_api_ver() return more useful information,
instead of just returning -EIO by propagating firmware errors back to the
caller and log a message if the PF sends an invalid reply.  Fix up a log
message that was missing a word, which makes the log message more readable.
Fix an initialization failure if many VFs are instantiated at the same time
and the VF module is autoloaded by simply resending firmware request if
there is no response the first time.

Jacob does a rename of the function i40e_ptp_enable() to
i40e_ptp_feature_enable(), like he did for ixgbe, to reduce possible
confusion and ambugity in the purpose of the function.  Does follow on
PTP work on i40e, like he did for ixgbe, by breaking the PTP hardware
control from the ioctl command for timestamping mode.  By doing this,
we can maintain state about the 1588 timestamping mode and properly
re-enable to the last known mode during a re-initialization of 1588 bits.

Anjali cleans up the i40e driver where TCP-IPv4 filters were being added
twice, which seems to be left over from when we had to add two PTYPEs for
one filter.  Fixes the flow director sideband logic to detect when there
is a full flow director table.  Also fixes the programming of FDIR where
a couple of fields in the descriptor setup that were not being
programmed, which left the opportunity for stale data to be pushed as
part of the descriptor next time it was used.

tipc: new unicast transmission code

As a step towards making the data transmission code more maintainable
and performant, we introduce a number of new functions, both for
building, sending and rejecting messages. The new functions will
eventually be used for alla data transmission, user data unicast,
service internal messaging, and multicast/broadcast.

We start with this series, where we introduce the functions, and
let user data unicast and the internal connection protocol use them.
The remaining users will come in a later series.

There are only minor changes to data structures, and no protocol
changes, so the older functions can still be used in parallel for
some time. Until the old functions are removed, we use temporary
names for the new functions, such as tipc_build_msg2, tipc_link_xmit2.

It should be noted that the first two commits are unrelated to the
rest of the series.

As a consequence of the recently introduced serialized access
to the socket in commit 8d94168a761819d10252bab1f8de6d7b202c3baa
("tipc: same receive code path for connection protocol and data
messages") we can make a number of simplifications in the
detection and handling of connection congestion situations.

- We don't need to keep two counters, one for sent messages and one
  for acked messages. There is no longer any risk for races between
  acknowledge messages arriving in BH and data message sending
  running in user context. So we merge this into one counter,
  'sent_unacked', which is incremented at sending and subtracted
  from at acknowledge reception.

- We don't need to set the 'congested' field in tipc_port to
  true before we sent the message, and clear it when sending
  is successful. (As a matter of fact, it was never necessary;
  the field was set in link_schedule_port() before any wakeup
  could arrive anyway.)

- We keep the conditions for link congestion and connection connection
  congestion separated. There would otherwise be a risk that an arriving
  acknowledge message may wake up a user sleeping because of link
  congestion.

- We can simplify reception of acknowledge messages.

We also make some cosmetic/structural changes:

- We rename the 'congested' field to the more correct 'link_cong´.

- We rename 'conn_unacked' to 'rcv_unacked'

- We move the above mentioned fields from struct tipc_port to
  struct tipc_sock.

We simplify the code for receiving connection probes, leveraging the
recently introduced tipc_msg_reverse() function. We also stick to
the principle of sending a possible response message directly from
the calling (tipc_sk_rcv or backlog_rcv) functions, hence making
the call chain shallower and easier to follow.

We make one small protocol change here, allowed according to
the spec. If a protocol message arrives from a remote socket that
is not the one we are connected to, we are currently generating a
connection abort message and send it to the source. This behavior
is unnecessary, and might even be a security risk, so instead we
now choose to only ignore the message. The consequnce for the sender
is that he will need longer time to discover his mistake (until the
next timeout), but this is an extreme corner case, and may happen
anyway under other circumstances, so we deem this change acceptable.

When a message arrives in a node and finds no destination
socket, we may need to drop it, reject it, or forward it after
a secondary destination lookup. The latter two cases currently
results in a code path that is perceived as complex, because it
follows a deep call chain via obscure functions such as
net_route_named_msg() and net_route_msg().

We now introduce a function, tipc_msg_eval(), that takes the
decision about whether such a message should be rejected or
forwarded, but leaves it to the caller to actually perform
the indicated action.

If the decision is 'reject', it is still the task of the recently
introduced function tipc_msg_reverse() to take the final decision
about whether the message is rejectable or not. In the latter case
it drops the message.

As a result of this change, we can finally eliminate the function
net_route_named_msg(), and hence become independent of net_route_msg().

also ensure that all calls to tipc_link_xmit2() are made outside
port_lock/bh_lock_sock.

Finally, we replace all calls to tipc_reject_msg() with the two new

Fragmentation at message sending is currently performed in two
places in link.c, depending on whether data to be transmitted
is delivered in the form of an iovec or as a big sk_buff. Those
functions are also tightly entangled with the send functions
that are using them.

We now introduce a re-entrant, standalone function, tipc_msg_build2(),
that builds a packet chain directly from an iovec. Each fragment is
sized according to the MTU value given by the caller, and is prepended
with a correctly built fragment header, when needed. The function is
independent from who is calling and where the chain will be delivered,
as long as the caller is able to indicate a correct MTU.

The function is tested, but not called by anybody yet. Since it is
incompatible with the existing tipc_msg_build(), and we cannot yet

such as handle reception of new packets.

In this commit, we make the MTUs of each active link become easily
accessible from the socket level, i.e., without taking any spinlock
or dereferencing the target link pointer. This way, we make it possible
to perform fragmentation in the sending socket, before sending the

The current link implementation provides several different transmit
functions, depending on the characteristics of the message to be
sent: if it is an iovec or an sk_buff, if it needs fragmentation or
not, if the caller holds the node_lock or not. The permutation of
these options gives us an unwanted amount of unnecessarily complex
code.

As a first step towards simplifying the send path for all messages,
we introduce two new send functions at link level, tipc_link_xmit2()
and __tipc_link_xmit2(). The former looks up a link to the message
destination, and if one is found, it grabs the node lock and calls
the second function, which works exclusively inside the node lock
protection. If no link is found, and the destination is on the same
node, it delivers the message directly to the local destination
socket.

The new functions take a buffer chain where all packet headers are
already prepared, and the correct MTU has been used. These two
functions will later replace all other link-level transmit functions.

The functions are not backwards compatible, so we have added them
as new functions with temporary names. They are tested, but have no
users yet. Those will be added later in this series.
