Ok, thanks for making an effort to look into this more thoroughly.

I'll apply this series to net-next, thank you.

This looks like a bug fix, completely unrelated to the feature being added
by this patch set.

Please submit this targetting the 'net' tree, then when that fix propagates
into 'net-next' you can rebase this series on top of that.

Thank you.

Adding Greg here.

Greg, apparently a backport of 46f1c52e66db is needed in 4.9 according
to the thread below. It was merged in 4.13 so 4.14 already has it.

It is indeed a lot of dup lines with sock_ops_convert_ctx_access()
as you mentioned in the cover.

Other than that, LGTM.

This ordering inconsistency could be a trap to write bpf_prog
but I guess it is too late to change now considering
bpf_sock_ops is also using this convention.

Just curious, we cannot always assume inet_sk and then uses
its inet_sport?

I think BPF_TASK_FD_QUERY is okay. Using BPF_ATTACH_QUERY indeed seems
a little bit broader to me as other query subcommands are possible to
query attachments with different input.

BPF_PROG_QUERY is also trying to query attachment. Currently, given a 
cgroup fd, it will query prog array attached. Sean has the patch to 
attach bpf programs to a RC device, and given a device fd, it will
query prog array attached to that device.

Totally agree.

Libvirt may pick any device under sys/bus/pci/devices/$vf/physfn/net/
to run legacy SR-IOV NDOs on.  nfp currently exposes those on all
representors.  

Or correctly points out that running SR-IOV NDOs on non-PF reprs makes
very limited amount of sense and we should fix libvirt and remove the
NDOs for non-PF nfp reprs.

AFAICT since nfp does provide the NDOs on all reprs nothing should
break with this patch, but ip link will now start listing VF state on
each representor.  Meaning that if we have 100 VFs enabled simple "ip
link list" will produce upwards of 10,000 lines of output.

* [PATCH v2 net-next 6/6] tcp: add tcp_comp_sack_nr sysctl

This per netns sysctl allows for TCP SACK compression fine-tuning.

This limits number of SACK that can be compressed.
Using 0 disables SACK compression.

This per netns sysctl allows for TCP SACK compression fine-tuning.

Its default value is 1,000,000, or 1 ms to meet TSO autosizing period.

* [PATCH v2 net-next 4/6] tcp: add TCPAckCompressed SNMP counter

This counter tracks number of ACK packets that the host has not sent,
thanks to ACK compression.

Sample output :

$ nstat -n;sleep 1;nstat|egrep "IpInReceives|IpOutRequests|TcpInSegs|TcpOutSegs|TcpExtTCPAckCompressed"
IpInReceives                    123250             0.0
IpOutRequests                   3684               0.0
TcpInSegs                       123251             0.0
TcpOutSegs                      3684               0.0

* [PATCH v2 net-next 3/6] tcp: add SACK compression
From: Eric Dumazet @ 2018-05-17 17:47 UTC (permalink / raw)
  To: David S . Miller
  Cc: netdev, Toke Høiland-Jørgensen, Neal Cardwell,
	Yuchung Cheng, Soheil Hassas Yeganeh, Eric Dumazet, Eric Dumazet
In-Reply-To: <20180517174739.192489-1-edumazet@google.com>

When TCP receives an out-of-order packet, it immediately sends
a SACK packet, generating network load but also forcing the
receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.

Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.

This patch adds a high resolution timer and tp->compressed_ack counter.

Instead of sending a SACK, we program this timer with a small delay,
based on SRTT and capped to 1 ms :

	delay = min ( 5 % of SRTT, 1 ms)

If subsequent SACKs need to be sent while the timer has not yet
expired, we simply increment tp->compressed_ack.

When timer expires, a SACK is sent with the latest information.
Whenever an ACK is sent (if data is sent, or if in-order
data is received) timer is canceled.

Note that tcp_sack_new_ofo_skb() is able to force a SACK to be sent
if the sack blocks need to be shuffled, even if the timer has not
expired.

A new SNMP counter is added in the following patch.

Two other patches add sysctls to allow changing the 1,000,000 and 44
values that this commit hard-coded.

* [PATCH v2 net-next 2/6] tcp: do not force quickack when receiving out-of-order packets

In-Reply-To: <20180517174739.192489-1-edumazet@google.com>

As explained in commit 9f9843a751d0 ("tcp: properly handle stretch
acks in slow start"), TCP stacks have to consider how many packets
are acknowledged in one single ACK, because of GRO, but also
because of ACK compression or losses.

We plan to add SACK compression in the following patch, we
must therefore not call tcp_enter_quickack_mode()

* [PATCH v2 net-next 0/6] tcp: implement SACK compression
From: Eric Dumazet @ 2018-05-17 17:47 UTC (permalink / raw)
  To: David S . Miller
  Cc: netdev, Toke Høiland-Jørgensen, Neal Cardwell,
	Yuchung Cheng, Soheil Hassas Yeganeh, Eric Dumazet, Eric Dumazet

When TCP receives an out-of-order packet, it immediately sends
a SACK packet, generating network load but also forcing the
receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.

Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.

This patch series adds SACK compression, but the infrastructure
could be leveraged to also compress ACK in the future.

v2: Addressed Neal feedback.
    Added two sysctls to allow fine tuning, or even disabling the feature.

Eric Dumazet (6):
  tcp: use __sock_put() instead of sock_put() in tcp_clear_xmit_timers()
  tcp: do not force quickack when receiving out-of-order packets
  tcp: add SACK compression
  tcp: add TCPAckCompressed SNMP counter
  tcp: add tcp_comp_sack_delay_ns sysctl
  tcp: add tcp_comp_sack_nr sysctl

I guess this one got lost somewhere as it doesn't appear in linux-4.9.y
(other trees aren't relevant).
If that's unintentional, than can you please re-queue
46f1c52e66db ("nfp: TX time stamp packets before HW doorbell is rung")
to -stable?

Sorry for noticing so late.

* [PATCH] selftests/bpf: check return value of fopen in test_verifier.c
From: Jesper Dangaard Brouer @ 2018-05-17 17:39 UTC (permalink / raw)
  To: netdev, Jesper Dangaard Brouer; +Cc: Daniel Borkmann, joe, Alexei Starovoitov

Commit 0a6748740368 ("selftests/bpf: Only run tests if !bpf_disabled")
forgot to check return value of fopen.

This caused some confusion, when running test_verifier (from
tools/testing/selftests/bpf/) on an older kernel (< v4.4) as it will
simply seqfault.

This fix avoids the segfault and prints an error, but allow program to
continue.  Given the sysctl was introduced in 1be7f75d1668 ("bpf:
enable non-root eBPF programs"), we know that the running kernel
cannot support unpriv, thus continue with unpriv_disabled = true.

Fixes: 0a6748740368 ("selftests/bpf: Only run tests if !bpf_disabled")

Now I have it compiled as module, and after modprobe dsa_loop I see:
[ 1168.129202] libphy: Fixed MDIO Bus: probed
[ 1168.222716] dsa-loop fixed-0:1f: DSA mockup driver: 0x1f

This messages I did not see when I had fixed_phy compiled as buildin.

But I still see no netdevs :/

Thanks for catching this and the quick fix. The path to hit this case
is to add a sock to a map (without a BPF program) where the sock already
has been added to another map. I don't have any tests for the case with
socks in multiple maps so I'll add some to the selftests so I remember
this case.

The alternative fix would be to always 'return 0' at the end of the
function, but I think its probably better to init err here like above.
