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.

The former is used to send - * UMAC commands (see UMAC_CMD_OPCODE_* from umac.h) - * while the latter is used for sending commands to the - * LMAC. If you look at LMAC commands you'll se that they - * are actually regular iwlwifi target commands encapsulated - * into a special UMAC command called UMAC passthrough. - * This is due to the fact the host talks exclusively - * to the UMAC and so there needs to be a special UMAC - * command for talking to the LMAC. - * This is how a wifi command is laid out: - * ------------------------ - * | iwm_udma_out_wifi_hdr | - * ------------------------ - * | SW meta_data (32 bits) | - * ------------------------ - * | iwm_dev_cmd_hdr | - * ------------------------ - * | payload | - * | .... | - * - * - non-wifi, or general commands: - * Those commands are handled by the device's bootrom, - * and are typically sent when the UMAC and the LMAC - * are not yet available. - * * This is how a non-wifi command is laid out: - * --------------------------- - * | iwm_udma_out_nonwifi_hdr | - * --------------------------- - * | payload | - * | .... | - - * - * All the commands start with a UDMA header, which is - * basically a 32 bits field.

When we do receive - * a command response from the UMAC, we go through the list - * of pending command, and pass both the command and the answer - * to the rx handler. Each command is sent with a unique - * sequence id, and the answer is sent with the same one.
