Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

Pull networking changes from David S Miller:

1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
trie and use prebuilt routes cached there.

No more garbage collection, no more rDOS attacks on the routing
cache. Instead we now get predictable and consistent performance,
no matter what the pattern of traffic we service.

This has been almost 2 years in the making. Special thanks to
Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
have helped along the way.

I'm sure that with a change of this magnitude there will be some
kind of fallout, but such things ought the be simple to fix at this
point. Luckily I'm not European so I'll be around all of August to
fix things :-)

The major stages of this work here are each fronted by a forced
merge commit whose commit message contains a top-level description
of the motivations and implementation issues.

2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
input.

3) TCP SYN/ACK performance tweaks from Eric Dumazet.

4) Add namespace support for netfilter L4 conntrack helpers, from Gao
Feng.

5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
Yuval Mintz.

6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.

7) Support for connection tracker helpers in userspace, from Pablo
Neira Ayuso.

8) Allow userspace driven TX load balancing functions in TEAM driver,
from Jiri Pirko.

9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
embedded gotos.

10) TCP Small Queues, essentially minimize the amount of TCP data queued
up in the packet scheduler layer. Whereas the existing BQL (Byte
Queue Limits) limits the pkt_sched --> netdevice queuing levels,
this controls the TCP --> pkt_sched queueing levels.

From Eric Dumazet.

11) Reduce the number of get_page/put_page ops done on SKB fragments,
from Alexander Duyck.

12) Implement protection against blind resets in TCP (RFC 5961), from
Eric Dumazet.

13) Support the client side of TCP Fast Open, basically the ability to
send data in the SYN exchange, from Yuchung Cheng.

Basically, the sender queues up data with a sendmsg() call using
MSG_FASTOPEN, then they do the connect() which emits the queued up
fastopen data.

14) Avoid all the problems we get into in TCP when timers or PMTU events
hit a locked socket. The TCP Small Queues changes added a
tcp_release_cb() that allows us to queue work up to the
release_sock() caller, and that's what we use here too. From Eric
Dumazet.

15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

1) Get rid of the error prone NLA_PUT*() macros that used an embedded
goto.

2) Kill off the token-ring and MCA networking drivers, from Paul
Gortmaker.

3) Reduce high-order allocations made by datagram AF_UNIX sockets, from
Eric Dumazet.

4) Add PTP hardware clock support to IGB and IXGBE, from Richard
Cochran and Jacob Keller.

5) Allow users to query timestamping capabilities of a card via
ethtool, from Richard Cochran.

6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part
of this is that we can now have BPF filters not attached to sockets,
and the loadbalancing function is calculated using one.

7) Francois Romieu went through the network drivers removing gratuitous
uses of netdev->base_addr, perhaps some day we can remove it
completely but it's used for ISA probing still.

8) Add a BPF JIT for sparc. I know, who cares, right? :-)

9) Move networking sysctl registry away from using the compatability
mode interfaces in the sysctl code. From Eric W Biederman.

10) Pavel Emelyanov added a way to save and restore TCP socket state via
TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as
well as a way to forcefully bind a socket to a port via the
sk->sk_reuse value SK_FORCE_REUSE. There is also a
TCP_REPAIR_OPTIONS which allows to reinstante the TCP options
enabled on the connection.

11) Several enhancements from Eric Dumazet that, in particular, can
enhance splice performance on TCP sockets significantly.

a) Reset the offset of the per-socket sendmsg page when we know
we're the only use of the page in linear_to_page().

b) Add facilities such that skb->data can be backed a page rather
than SLAB kmalloc'd memory. In particular devices which were
receiving into linear RX buffers can now end up providing paged
data.

The big result is that code like splice and GRO do not have to copy
any more.

12) Allow a pure sender to more gracefully handle ACK backlogs in TCP.
What can happen at high rates is that the sender hasn't grown his
receive buffer limits at all (he's not receiving data so really
doesn't need to), but the non-data ACKs consume receive buffer
space.

sk_add_backlog() is too aggressive in dropping frames in this case,
so relax it's requirements by using the receive buffer plus the send
buffer limit as the backlog limit instead of just the former.

Also from Eric Dumazet.

13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and
Chris Elston.

14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng.
Basically, we can start fast retransmit before hiting the dupack
threshold under certain conditions.

15) New CODEL active queue management packet scheduler, from Eric
Dumazet based upon initial work by Dave Taht.

Basically, the big feature is that packets are dropped (or ECN bits
are set) based upon how long packets live in the queue, rather than
the queue length (which is what RED uses).

Merge tag 'isci-for-3.5' into misc

isci update for 3.5

1/ Rework remote-node-context (RNC) handling for proper management of
the silicon state machine in error handling and hot-plug conditions.
Further details below, suffice to say if the RNC is mismanaged the
silicon state machines may lock up.

2/ Refactor the initialization code to be reused for suspend/resume support

3/ Miscellaneous bug fixes to address discovery issues and hardware
compatibility.

RNC rework details from Jeff Skirvin:

In the controller, devices as they appear on a SAS domain (or
direct-attached SATA devices) are represented by memory structures known
as "Remote Node Contexts" (RNCs). These structures are transferred from
main memory to the controller using a set of register commands; these
commands include setting up the context ("posting"), removing the
context ("invalidating"), and commands to control the scheduling of
commands and connections to that remote device ("suspensions" and
"resumptions"). There is a similar path to control RNC scheduling from
the protocol engine, which interprets the results of command and data
transmission and reception.

In general, the controller chooses among non-suspended RNCs to find one
that has work requiring scheduling the transmission of command and data
frames to a target. Likewise, when a target tries to return data back
to the initiator, the state of the RNC is used by the controller to
determine how to treat the incoming request. As an example, if the RNC
is in the state "TX/RX Suspended", incoming SSP connection requests from
the target will be rejected by the controller hardware. When an RNC is
"TX Suspended", it will not be selected by the controller hardware to
start outgoing command or data operations (with certain priority-based
exceptions).

As mentioned above, there are two sources for management of the RNC
states: commands from driver software, and the result of transmission
and reception conditions of commands and data signaled by the controller
hardware. As an example of the latter, if an outgoing SSP command ends
with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will
transition to the "TX Suspended" state, and this is signaled by the
controller hardware in the status to the completion of the pending
command as well as signaled in a controller hardware event. Examples of
the former are included in the patch changelogs.

Driver software is required to suspend the RNC in a "TX/RX Suspended"
condition before any outstanding commands can be terminated. Failure to
guarantee this can lead to a complete hardware hang condition. Earlier
versions of the driver software did not guarantee that an RNC was
correctly managed before I/O termination, and so operated in an unsafe
way.

Further, the driver performed unnecessary contortions to preserve the
remote device command state and so was more complicated than it needed
to be. A simplifying driver assumption is that once an I/O has entered
the error handler path without having completed in the target, the
requirement on the driver is that all use of the sas_task must end.
Beyond that, recovery of operation is dependent on libsas and other
components to reset, rediscover and reconfigure the device before normal
operation can restart. In the driver, this simplifying assumption meant
that the RNC management could be reduced to entry into the suspended
state, terminating the targeted I/O request, and resuming the RNC as
needed for device-specific management such as an SSP Abort Task or LUN
Reset Management request.
