git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Al Viro says: ==================== netdev-related stuff in vfs.git There are several commits sitting in vfs.git that probably ought to go in via net-next.git. First of all, there's merge with vfs.git#iocb - that's Christoph's aio rework, which has triggered conflicts with the ->sendmsg() and ->recvmsg() patches a while ago. It's not so much Christoph's stuff that ought to be in net-next, as (pretty simple) conflict resolution on merge. The next chunk is switch to {compat_,}import_iovec/import_single_range - new safer primitives for initializing iov_iter. The primitives themselves come from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue), conversion of net/socket.c syscalls belongs in net-next, IMO. Next there's afs and rxrpc stuff from dhowells. And then there's sanitizing kernel_sendmsg et.al. + missing inlined helper for "how much data is left in msg->msg_iter" - this stuff is used in e.g. cifs stuff, but it belongs in net-next. That pile is pullable from git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem I'll post the individual patches in there in followups; could you take a look and tell if everything in there is OK with you? ==================== Signed-off-by: David S.

2015-04-13tcp/dccp: get rid of central timewait timerEric Dumazet11-386/+69
Using a timer wheel for timewait sockets was nice ~15 years ago when memory was expensive and machines had a single processor. This does not scale, code is ugly and source of huge latencies (Typically 30 ms have been seen, cpus spinning on death_lock spinlock.) We can afford to use an extra 64 bytes per timewait sock and spread timewait load to all cpus to have better behavior. Tested: On following test, /proc/sys/net/ipv4/tcp_tw_recycle is set to 1 on the target (lpaa24) Before patch : lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0 419594 lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0 437171 While test is running, we can observe 25 or even 33 ms latencies. lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23 ... 1000 packets transmitted, 1000 received, 0% packet loss, time 20601ms rtt min/avg/max/mdev = 0.020/0.217/25.771/1.535 ms, pipe 2 lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23 ... 1000 packets transmitted, 1000 received, 0% packet loss, time 20702ms rtt min/avg/max/mdev = 0.019/0.183/33.761/1.441 ms, pipe 2 After patch : About 90% increase of throughput : lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0 810442 lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0 800992 And latencies are kept to minimal values during this load, even if network utilization is 90% higher : lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23 ... 1000 packets transmitted, 1000 received, 0% packet loss, time 19991ms rtt min/avg/max/mdev = 0.023/0.064/0.360/0.042 ms Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2015-04-13tcp: fix bogus RTT for CC when retransmissions are ackedKenneth Klette Jonassen1-6/+4
Since retransmitted segments are not used for RTT estimation, previously SACKed segments present in the rtx queue are used. This estimation can be several times larger than the actual RTT. When a cumulative ack covers both previously SACKed and retransmitted segments, CC may thus get a bogus RTT. Such segments previously had an RTT estimation in tcp_sacktag_one(), so it seems reasonable to not reuse them in tcp_clean_rtx_queue() at all. Afaik, this has had no effect on SRTT/RTO because of Karn's check.

2015-04-13net: use jump label patching for ingress qdisc in __netif_receive_skb_coreDaniel Borkmann3-8/+47
Even if we make use of classifier and actions from the egress path, we're going into handle_ing() executing additional code on a per-packet cost for ingress qdisc, just to realize that nothing is attached on ingress. Instead, this can just be blinded out as a no-op entirely with the use of a static key. On input fast-path, we already make use of static keys in various places, e.g. skb time stamping, in RPS, etc. It makes sense to not waste time when we're assured that no ingress qdisc is attached anywhere. Enabling/disabling of that code path is being done via two helpers, namely net_{inc,dec}_ingress_queue(), that are being invoked under RTNL mutex when a ingress qdisc is being either initialized or destructed.

The entire set of changes come from Vlad Zolotarov to ultimately add the ethtool ops to VF driver to allow querying the RSS indirection table and RSS random key. Currently we support only 82599 and x540 devices. On those devices, VFs share the RSS redirection table and hash key with a PF. Letting the VF query this information may introduce some security risks, therefore this feature will be disabled by default.

Add this new command for 82599 and x540 devices only. Support for other devices will be added later. 82599 and x540 VFs and PF share the same RSS redirection table (RETA). Therefore we just return it for all VFs. For 82599 and x540 RETA table is an array of 32 registers (128 bytes) and the maximum number of registers that may be delivered in a single VF-PF channel command is 15. On the other hand VFs of these devices can be configured to have up to 4 RSS queues. Therefore we will "compress" the RETA by transferring only 2 bits per entry and thereby it will take only 8 registers (DWORDS) to transfer the whole VF RETA. Thus this patch does the following: - Adds a new API version (to specify a new commands set). - Adds the IXGBE_VF_GET_RETA command to the VF-PF commands set.
